THE COMPANY Comfort Systems was founded in 1996 to become a leading national provider of comprehensive HVAC installation services and maintenance, repair and replacement of HVAC systems, focusing primarily on the commercial and industrial markets. The Company's commercial and industrial applications include office buildings, retail centers, apartment complexes, hotels, manufacturing plants and government facilities. The Company also provides specialized HVAC applications such as process cooling, control systems, electronic monitoring and process piping. Approximately 90% of the Company's pro forma combined 1996 revenues of $167.5 million was derived from commercial and industrial customers, with approximately 53% of combined revenues attributable to installation services and 47% attributable to maintenance, repair and replacement services. Combined revenues of the Founding Companies, which have been in business an average of 39 years, increased at a compound annual growth rate of approximately 16% from 1994 through 1996. Based on available industry data, the Company believes that the HVAC industry is highly fragmented with over 40,000 companies, most of which are small, owner-operated businesses with limited access to capital for modernization and expansion. The overall HVAC industry, including the commercial, industrial and residential markets, is estimated to generate annual revenues in excess of $75 billion, over $35 billion of which is in the commercial and industrial markets. The Company believes there is a significant opportunity for a well-capitalized national company to provide comprehensive HVAC services and that the fragmented nature of the HVAC industry will provide it with significant opportunities to consolidate commercial, industrial and residential HVAC businesses. The Company's commercial and industrial installation business targets "design and build" projects where the Company is responsible for designing, engineering and installing a cost-effective, energy-efficient system, customized to meet the specific needs of the building owner. Management believes that the "design and build" segment represents a faster growing and more profitable segment of the HVAC business than traditional "plan and spec" installation. The cost and other terms of "design and build" projects are normally negotiated between the building owner or its representative and the Company, thereby providing single point responsibility for the building owner and enabling the Company to reduce the customer's cost as well as overall design and installation time. "Plan and spec" installation refers to projects where an architect or a consulting engineer designs the HVAC system and the installation project is put out for bid. In recent years, the Company has undertaken a shift from "plan and spec" to "design and 3 build" projects with "design and build" revenues increasing from approximately 65% of installation revenues in 1994 to approximately 80% in 1996. Growth in the maintenance, repair and replacement business is driven by a number of factors, particularly (i) the aging of the installed base, (ii) the increasing energy efficiency, sophistication and complexity of HVAC systems and (iii) the increasing restrictions on the use of refrigerants commonly used in older HVAC systems. The energy efficiency and sophistication of new HVAC systems are encouraging building owners to upgrade and reconfigure their current HVAC systems. Moreover, the increasing sophistication and complexity of these HVAC systems are leading many commercial and industrial building owners and property managers to outsource maintenance and repair through service agreements with HVAC service providers. Service agreements lead to better utilization of personnel, link the customer with the Company should a major repair or replacement be needed and result in recurring revenues. The Company believes there is also an opportunity to expand its presence in the highly fragmented residential maintenance, repair and replacement market. The replacement segment of the residential HVAC market has grown significantly in recent years as a result of the aging of the installed base of residential HVAC systems, the introduction of more energy-efficient systems and the upgrading of older homes with central air conditioning. The Company plans to achieve its goal of becoming a leading national provider of comprehensive HVAC services by improving operations, emphasizing continued internal growth and expanding through acquisitions. OPERATING STRATEGY. The Company believes there are significant opportunities to increase the profitability of the Founding Companies and subsequently acquired businesses. The key elements of the Company's operating strategy are: FOCUS ON COMMERCIAL AND INDUSTRIAL MARKETS. The Company believes that the commercial and industrial HVAC markets are attractive because of their growth opportunities, diverse customer base, attractive margins and potential for long-term relationships with building owners and managers, general contractors and architects. OPERATE ON DECENTRALIZED BASIS. The Company believes that, while maintaining strong operating and financial controls, a decentralized operating structure will retain the entrepreneurial spirit present in each of the Founding Companies and will allow the Company to capitalize on the considerable local and regional market knowledge and customer relationships possessed by each Founding Company. ACHIEVE OPERATING EFFICIENCIES. The Company intends to use its increased purchasing power to gain volume discounts in areas such as HVAC components, raw materials, service vehicles, advertising, bonding and insurance. In addition, the Company will identify "best practices" that can be successfully implemented throughout its operations. ATTRACT AND RETAIN QUALITY EMPLOYEES. The Company intends to attract and retain quality employees by providing them (i) an enhanced career path from working for a larger public company, (ii) additional training, education and apprenticeships to allow talented employees to advance to higher-paying positions, (iii) the opportunity to realize a more stable income and (iv) improved benefits packages. INTERNAL GROWTH. A key component of the Company's strategy is to continue the internal growth at the Founding Companies and subsequently acquired businesses. The key elements of the Company's internal growth strategy are: CAPITALIZE ON SPECIALIZED TECHNICAL AND MARKETING STRENGTHS. The Company believes it will be able to expand the services it offers in its local markets by leveraging the specialized technical and marketing strengths of individual Founding Companies. 4 ESTABLISH NATIONAL MARKET COVERAGE. The Company believes that significant demand exists from large national companies to utilize the services of a single HVAC service provider and believes existing local and regional relationships can be expanded as it develops a nationwide network. ACQUISITIONS. The Company believes that, due to the highly fragmented nature of the HVAC industry, it has a significant opportunity to achieve its acquisition strategy. The Company anticipates that acquisition candidates in the commercial and industrial markets will typically have annual revenues ranging from $5 million to $35 million. The key elements of the Company's acquisition strategy are: ENTER NEW GEOGRAPHIC MARKETS. The Company will pursue acquisitions that are located in new geographic markets, are financially stable, and which will have the customer base, technical skills and infrastructure necessary to be a core business into which other HVAC service operations can be consolidated. EXPAND WITHIN EXISTING MARKETS. Once the Company has entered a market, it will seek to acquire other well-established HVAC businesses operating within that region and will also pursue "tuck-in" acquisitions of smaller companies, whose operations can be integrated into an existing operation to leverage the Company's infrastructure. ACQUIRE COMPLEMENTARY BUSINESSES. The Company will focus on the HVAC industry and may also acquire companies providing complementary services to the same customer base, such as commercial and industrial process piping and plumbing and electrical companies.

RECENT DEVELOPMENTS During January and February 1997, Comfort Systems sold an aggregate of 1,269,935 shares of Common Stock to management of and consultants to the Company for $0.01 per share. As a result, the Company will record a non-recurring, non-cash compensation charge of $6.5 million in the first quarter of 1997, representing the difference between the amount paid for the shares and the estimated fair value of the shares on the date of sale.

IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING AN INVESTMENT IN THE COMMON STOCK. THIS PROSPECTUS CONTAINS CERTAIN FORWARD-LOOKING STATEMENTS. ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE PROJECTED IN THE FORWARD-LOOKING STATEMENTS AS A RESULT OF ANY NUMBER OF FACTORS, INCLUDING THE RISK FACTORS SET FORTH BELOW AND ELSEWHERE IN THIS PROSPECTUS. ABSENCE OF COMBINED OPERATING HISTORY. Comfort Systems was founded in 1996 but has conducted no operations and generated no revenues to date. Comfort Systems has entered into definitive agreements to acquire the Founding Companies simultaneously with and as a condition to the closing of this Offering. The Founding Companies have been operating as separate independent entities, and there can be no assurance that the Company will be able to integrate the operations of these businesses successfully or to institute the necessary systems and procedures, including accounting and financial reporting systems, to manage the combined enterprise on a profitable basis. The Company's management group has been assembled only recently, and there can be no assurance that the management group will be able to manage the combined entity or to implement effectively the Company's operating strategy, internal growth strategy and acquisition program. The pro forma combined historical financial results of the Founding Companies cover periods when the Founding Companies and Comfort Systems were not under common control or management and may not be indicative of the Company's future financial or operating results. The inability of the Company to integrate the Founding Companies successfully would have a material adverse effect on the Company's business, financial condition and results of operations and would make it unlikely that the Company's acquisition program will be successful. See "Business -- Strategy" and "Management." RISKS RELATED TO THE COMPANY'S ACQUISITION STRATEGY. The Company intends to grow significantly through the acquisition of additional HVAC and complementary businesses. The Company expects to face competition for acquisition candidates, which may limit the number of acquisition opportunities and may lead to higher acquisition prices. There can be no assurance that the Company will be able to identify, acquire or manage profitably additional businesses or to integrate successfully any acquired businesses into the Company without substantial costs, delays or other operational or financial problems. Further, acquisitions involve a number of special risks, including failure of the acquired business to achieve expected results, diversion of management's attention, failure to retain key personnel of the acquired business and risks associated with unanticipated events or liabilities, some or all of which could have a material adverse effect on the Company's business, financial condition and results of operations. Customer dissatisfaction or performance problems at a single acquired company could have an adverse effect on the reputation of the Company generally and render ineffective the Company's national sales and marketing initiatives. The Company may consider acquiring complementary businesses in the electrical, process piping and plumbing industries, and there can be no assurance that these complementary businesses can be successfully integrated. In addition, there can be no assurance that the Founding Companies or other businesses acquired in the future will achieve anticipated revenues and earnings. See "Business -- Strategy." RISKS RELATED TO ACQUISITION FINANCING. The timing, size and success of the Company's acquisition efforts and the associated capital commitments cannot be readily predicted. The Company currently intends to finance future acquisitions by using shares of its Common Stock for all or a substantial portion of the consideration to be paid. If the Common Stock does not maintain a sufficient market value, or if potential acquisition candidates are otherwise unwilling to accept Common Stock as part of the consideration for the sale of their businesses, the Company may be required to utilize more of its cash resources, if available, in order to initiate and maintain its acquisition program. Upon completion of this Offering, the Company will have $24.4 million of net proceeds remaining for future acquisitions and working capital after payment of Merger and Offering expenses and the cash portion of the purchase price for the Founding Companies. If the Company does not have sufficient cash resources, its growth could be limited unless it is able to obtain additional capital through debt or equity financings. Upon consummation of this Offering, the Company intends to obtain a bank line of credit of at least $50 million for working capital and acquisitions. However, 11 there can be no assurance that the Company will be able to obtain the line of credit or additional financing it will need for its acquisition program on terms that the Company deems acceptable. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." RISKS RELATED TO OPERATING AND INTERNAL GROWTH STRATEGY. Key elements of the Company's strategy are to improve the profitability of the Founding Companies and subsequently acquired businesses and to continue to expand the revenues of the Founding Companies and any subsequently acquired businesses. The Company intends to seek to improve the profitability of the Founding Companies and any subsequently acquired businesses by various means, including a reduction, in some cases, of duplicative operating costs and overhead and purchasing efficiencies. The Company's ability to increase the revenues of the Founding Companies and any subsequently acquired company will be affected by various factors, including demand for new or replacement HVAC systems, the level of new construction, the Company's ability to expand the range of services offered to customers of individual Founding Companies and other acquired businesses, the Company's ability to develop national accounts and other marketing programs in order to attract new customers and the Company's ability to attract and retain a sufficient number of qualified HVAC technicians and other necessary personnel. Many of these factors are beyond the control of the Company, and there can be no assurance that the Company's operating and internal growth strategies will be successful or that it will be able to generate cash flow adequate for its operation and to support internal growth. See "Business -- Strategy." COMPETITION. The HVAC industry is highly competitive and is served by small, owner-operated private companies and several large companies. Certain of these competitors may have lower overhead cost structures and may, therefore, be able to provide their services at lower rates than the Company. The HVAC industry is currently undergoing rapid consolidation on both a national and a regional level by other companies which have acquisition objectives the same as or similar to the Company's objectives. These companies and other consolidators may have greater financial resources than the Company to finance acquisition and internal growth opportunities and might be willing to pay higher prices than the Company for the same acquisition opportunities. Additionally, HVAC equipment manufacturers and certain public utilities are beginning to enter the maintenance, repair and replacement segment of the HVAC industry. These companies generally are better capitalized, have greater name recognition and may be able to provide these services at a lower cost. Consequently, the Company may encounter significant competition in its efforts to achieve both its acquisition and internal growth objectives as well as its operating strategy to increase the profitability of the Founding Companies and subsequently acquired companies. See "Business -- Competition." AVAILABILITY OF HVAC TECHNICIANS. The timely provision of high-quality installation service and maintenance, repair and replacement of HVAC systems by the Company requires an adequate supply of skilled HVAC technicians. Accordingly, the Company's ability to increase its productivity and profitability will be limited by its ability to employ, train and retain the skilled technicians necessary to meet the Company's service requirements. From time to time, there are shortages of qualified HVAC technicians, and there can be no assurance that the Company will be able to maintain an adequate skilled labor force necessary to operate efficiently, that the Company's labor expenses will not increase as a result of a shortage in the supply of skilled technicians or that the Company will not have to curtail its planned internal growth as a result of labor shortages. See "Business -- Employees" and " -- Recruiting, Training and Safety." SEASONAL AND CYCLICAL NATURE OF THE HVAC INDUSTRY. The HVAC industry is subject to seasonal variations. Specifically, the demand for new installations is generally lower during the winter months due to reduced construction activities during inclement weather and less use of air conditioning during the colder months. Demand for HVAC maintenance, repair and replacement services is generally higher in the second and third quarters due to the increased use of air conditioning during the warmer months. Accordingly, the Company expects its revenues and operating results generally will be lower in the first and fourth quarters. Historically, the construction industry has been highly cyclical. As a result, the Company's volume of 12 business may be adversely affected by declines in new installation projects in various geographic regions of the United States. REGULATION. HVAC systems are subject to various environmental statutes and regulations, including the Clean Air Act and those regulating the production, servicing and disposal of certain ozone depleting refrigerants used in HVAC systems. There can be no assurance that the regulatory environment in which the Company operates will not change significantly in the future. Various local, state and federal laws and regulations impose licensing standards on technicians who install and service HVAC systems. The Company's failure to comply with these laws and regulations could subject it to substantial fines and the loss of its licenses. See "Business -- Governmental Regulation and Environmental Matters." RELIANCE ON KEY PERSONNEL. The Company will be highly dependent on the continuing efforts of its executive officers and the senior management of the Founding Companies, and the Company likely will depend on the senior management of any significant business it acquires in the future. The business or prospects of the Company could be affected adversely if any of these persons does not continue in his management role until the Company is able to attract and retain qualified replacements. See "Management." CONTROL BY EXISTING MANAGEMENT AND STOCKHOLDERS. Following the completion of the Mergers and this Offering, the Company's executive officers and directors, former stockholders of the Founding Companies and entities affiliated with them will beneficially own approximately 69.6% of the outstanding shares of Common Stock (66.6% if the Underwriters' over-allotment option is exercised in full). These persons, if acting in concert, will be able to exercise control over the Company's affairs, to elect the entire Board of Directors and to control the outcome of any matter submitted to a vote of stockholders. See "Principal Stockholders." SUBSTANTIAL PROCEEDS OF OFFERING PAYABLE TO AFFILIATES OF FOUNDING COMPANIES. Of the net proceeds of this Offering, $45.3 million, or approximately 65%, of the net proceeds of this Offering will be paid as the cash portion of the purchase price for the Founding Companies. Some of the recipients of these funds will become directors of the Company or holders of more than 5% of the Common Stock. Additionally, Notre has advanced to Comfort Systems certain organization expenses and Offering costs and will be reimbursed approximately $825,000 from the proceeds of this Offering. See "Use of Proceeds" and "Certain Transactions." NO PRIOR PUBLIC MARKET AND DETERMINATION OF OFFERING PRICE. Prior to this Offering, there has been no public market for the Common Stock. Therefore, the initial public offering price for the Common Stock will be determined by negotiation between the Company and the Representatives of the Underwriters and may bear no relationship to the price at which the Common Stock will trade after the Offering. See "Underwriting" for the factors to be considered in determining the initial public offering price. The Common Stock has been approved for quotation on The New York Stock Exchange, subject to official notice of issuance. However, there can be no assurance that an active trading market will develop subsequent to this Offering or, if developed, that it will be sustained. After this Offering, the market price of the Common Stock may be subject to significant fluctuations in response to numerous factors, including the timing of any acquisitions by the Company, variations in the Company's annual or quarterly financial results or those of its competitors, changes by financial research analysts in their estimates of the future earnings of the Company, conditions in the economy in general or in the Company's industry in particular, unfavorable publicity or changes in applicable laws and regulations (or judicial or administrative interpretations thereof) affecting the Company or the HVAC, process piping and plumbing and electrical services industries. From time to time, the stock market experiences significant price and volume volatility, which may affect the market price of the Common Stock for reasons unrelated to the Company's performance. POTENTIAL EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE ON PRICE OF COMMON STOCK. Upon consummation of the Mergers and this Offering, 20,060,774 shares of Common Stock will be outstanding. The 6,100,000 shares sold in this Offering (other than shares that may be purchased by affiliates of the Company) will be freely tradable. The remaining outstanding shares may be resold publicly only following their registration under the Securities Act of 1933, as amended (the "Securities Act"), or pursuant to an available exemption 13 from registration (such as provided by Rule 144 following a one year holding period for previously unregistered shares). The holders of these remaining shares have certain rights to have their shares registered in the future under the Securities Act, but may not exercise such registration rights, and have agreed with the Company that they will not sell, transfer or otherwise dispose of any of their shares, for one year following the closing of this Offering. See "Shares Eligible for Future Sale." On completion of this Offering, the Company also will have outstanding options to purchase up to a total of 1,976,954 shares of Common Stock. The Company intends to register all the shares subject to these options under the Securities Act for public resale. The Company intends to register 8,000,000 additional shares of Common Stock under the Securities Act within 90 days after completion of its offering for issuance in connection with future acquisitions. These shares generally will be freely tradable after their issuance by persons not affiliated with the Company unless the Company contractually restricts their resale. POSSIBLE ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER PROVISIONS. Comfort Systems' Amended and Restated Certificate of Incorporation (the "Certificate of Incorporation"), authorizes the Board of Directors to issue, without stockholder approval, one or more series of preferred stock having such preferences, powers and relative, participating, optional and other rights (including preferences over the Common Stock respecting dividends and distributions and voting rights) as the Board of Directors may determine. The existence of this "blank-check" preferred stock could render more difficult or discourage an attempt to obtain control of the Company by means of a tender offer, merger, proxy contest or otherwise. In addition, the Certificate of Incorporation provides for a classified Board of Directors, which may also have the effect of inhibiting or delaying a change in control of the Company. Certain provisions of the Delaware General Corporation Law may also discourage takeover attempts that have not been approved by the Board of Directors. See "Description of Capital Stock." IMMEDIATE AND SUBSTANTIAL DILUTION. Purchasers of Common Stock in this Offering will experience immediate, substantial dilution in the net tangible book value of their stock of $11.52 per share and may experience further dilution in that value from issuances of Common Stock in connection with future acquisitions. See "Dilution." 14 USE OF PROCEEDS The net proceeds from the sale of the 6,100,000 shares of Common Stock offered hereby, after deducting underwriting discounts and commissions and estimated Offering and Merger expenses, are estimated to be $69.7 million ($80.8 million if the Underwriters' over-allotment option is exercised in full). Of the net proceeds, $45.3 million will be used to pay the cash portion of the purchase price for the Founding Companies, some of which will be paid to stockholders who will become directors or holders of more than 5% of the Common Stock. The $24.4 million of remaining net proceeds will be used for working capital and other general corporate purposes, which are expected to include future acquisitions. The Company currently has no binding agreements to effect any future acquisitions. Pending such uses, the net proceeds will be invested in short-term, interest-bearing, investment grade securities. The Company is currently negotiating with a group of banks to obtain a credit facility of at least $50 million, which would be available upon the consummation of this Offering. There can be no assurance that any line of credit will be obtained or that, if obtained, it will be on terms that are favorable to the Company. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Combined Results of Operations." DIVIDEND POLICY The Company intends to retain all of its future earnings, if any, to finance the expansion of its business and for general corporate purposes, including future acquisitions, and does not anticipate paying any cash dividends on its Common Stock for the foreseeable future. In addition, if the Company is successful in obtaining a credit facility, it is likely that such facility will include restrictions on the ability of the Company to pay dividends without the consent of the lender. In connection with the consummation of the Mergers, certain of the Founding Companies intend to make S Corporation Distributions, aggregating $16.6 million, to their former stockholders. In addition, each of the Founding Companies, except Atlas, will make Interim Earnings Distributions immediately prior to the Mergers. 15 CAPITALIZATION The following table sets forth the current maturities of long-term obligations and capitalization at December 31, 1996 (i) of the Founding Companies combined; (ii) of Comfort Systems on a pro forma combined basis to give effect to the issuance of 1,269,935 shares of Common Stock to management of and consultants to Comfort Systems, the Mergers and the S Corporation Distributions; and (iii) of Comfort Systems, pro forma combined, as adjusted to give effect to the Mergers, the S Corporation Distributions, this Offering and the application of a portion of the estimated net proceeds therefrom. This table should be read in conjunction with the Unaudited Pro Forma Combined Financial Statements of the Company and the Notes thereto included elsewhere in this Prospectus.

See "Management -- 1997 Long-Term Incentive Plan" and "-- 1997 Non-Employee Directors' Stock Plan." 16 DILUTION The deficit in pro forma combined net tangible book value of the Company at December 31, 1996 was $40.0 million or $2.87 per share of Common Stock. The deficit in pro forma combined net tangible book value per share represents the amount by which the Company's pro forma combined total liabilities exceeds the Company's pro forma combined net tangible assets, divided by the number of shares of Common Stock to be outstanding after giving effect to the Mergers. After giving effect to the sale of the 6,100,000 shares of Common Stock in this Offering and after deduction of the underwriting discounts and commissions and estimated Offering and Merger expenses, the pro forma combined net tangible book value of the Company at December 31, 1996 would have been approximately $29.8 million or $1.48 per share. This represents an immediate increase in pro forma combined net tangible book value of $4.35 per share to existing stockholders and an immediate dilution of $11.52 per share to purchasers of Common Stock in this Offering. The following table illustrates this pro forma dilution: Assumed initial public offering price per share............................. $ 13.00 Pro forma combined deficit in net tangible book value per share before this Offering.............. $ (2.87) Increase in pro forma combined net tangible book value per share attributable to new investors..... 4.35 --------- Pro forma combined net tangible book value per share after this Offering... 1.48 --------- Dilution per share to new investors..... $ 11.52 ========= The following table sets forth, on a pro forma combined basis to give effect to the Mergers at December 31, 1996, the number of shares of Common Stock purchased from the Company, the total consideration paid and the average price per share paid by existing stockholders and the new investors purchasing shares of Common Stock from the Company in this Offering, before deducting underwriting discounts and commissions and estimated Offering and Merger expenses:

INTRODUCTION The Company's revenues are derived from providing comprehensive HVAC installation services and maintenance, repair and replacement of HVAC systems primarily for commercial and industrial customers. The Company's commercial and industrial applications include office buildings, retail centers, apartment complexes, hotels, manufacturing plants and government facilities. The Company also provides specialized HVAC applications such as process cooling, control systems, electronic monitoring and process piping. Approximately 90% of the Company's pro forma combined 1996 revenues of $167.5 million was derived from commercial and industrial customers, with approximately 53% of total revenues attributable to installation services and 47% attributable to maintenance, repair and replacement services. Revenues related to commercial and industrial installation are of two types: "design and build" and "plan and spec." Approximately 80% of the commercial and industrial installation revenues for 1996 were generated from "design and build" projects, which generally yield higher margins than "plan and spec" projects because the Company is responsible for designing, engineering and installing a cost-effective, energy-efficient system that is customized to the specific needs of the building owner. This enables the Company to control the customer's cost and reduce overall design and installation time. Additionally, the costs and other terms of "design and build" projects are normally established through relationship-based negotiation with the building owner or its representative rather than through a competitive bid process. "Plan and spec" installation projects typically yield lower margins than "design and build" projects because the building's architect or consulting engineer designs the HVAC system and the installation project is put out for bid. Most installation and reconfiguration projects are completed within one year. Generally, these contracts are accounted for under the percentage-of-completion method of accounting. Revenues are recorded based on the percentage of costs incurred during a particular period, in proportion to total estimated costs for each contract. Maintenance, repair and replacement service revenues are recorded as services are performed. Costs of services consist primarily of HVAC components, parts and materials related to new installation, equipment maintenance and rental, salaries and benefits payable to service and repair technicians, as well as supervisory and subcontract labor. Selling, general and administrative expenses consist primarily of compensation and benefits to owners as well as to sales and administrative employees, fees for professional services, depreciation of equipment and other general office expenses. Selling, general and administrative expenses also include incentive and discretionary bonuses paid to owners, significant portions of which were paid in lieu of S Corporation distributions to enable stockholders to meet their income tax obligations. The Founding Companies have operated throughout the periods presented as independent, privately-owned entities, and their results of operations reflect varying tax structures (S Corporations or C Corporations) which have influenced the historical level of owners' compensation. Gross profit margins and selling, general and administrative expenses as a percentage of revenues may not be comparable among the individual Founding Companies. The owners of the Founding Companies have agreed to certain reductions in their compensation and benefits in connection with the organization of the Company. The Compensation Differential for 1996 of $6.6 million has been reflected as a pro forma adjustment in the Unaudited Pro Forma Combined Statements of Operations. The Company anticipates that following the Mergers it will realize savings from (i) greater volume discounts from suppliers of HVAC components, parts and raw materials; (ii) consolidation of insurance and bonding programs; (iii) other general and administrative areas such as training and advertising; and (iv) the Company's ability to borrow at lower interest rates than most of the Founding Companies. It is anticipated 20 that these savings will be offset by costs related to the Company's new corporate management and by the costs associated with being a public company. However, because these savings and costs cannot be accurately quantified at this time, they have not been included in the pro forma financial information included herein. During January and February 1997, Comfort Systems sold an aggregate of 1,269,935 shares of Common Stock to management and consultants. As a result, the Company will record a non-recurring, non-cash compensation charge of $6.5 million in the first quarter of 1997, representing the difference between the amount paid for the shares and the estimated fair value of the shares on the date of sale. In July 1996, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 97 ("SAB 97") relating to business combinations immediately prior to an initial public offering. SAB 97 requires that these combinations be accounted for using the purchase method of acquisition accounting. Under the purchase method, one of the Founding Companies must be designated as the accounting acquiror. For the remaining Founding Companies, $103.2 million, representing the excess of the fair value of the Merger consideration received over the fair value of the net assets to be acquired, will be recorded as "goodwill" on the Company's balance sheet. Goodwill will be amortized as a non-cash charge to the income statement over a 40-year period. The pro forma impact of this amortization expense, which is non-deductible for tax purposes, is $2.6 million per year on an after-tax basis. Prior to the issuance of SAB 97, goodwill and related amortization expense were not required to be recorded for most business combinations similar to the Mergers. The amount of goodwill to be recorded and the related amortization expense will depend in part on the actual Offering price. See "Certain Transactions -- Organization of the Company." COMBINED RESULTS OF OPERATIONS The combined results of operations of the Founding Companies for the periods presented do not represent combined results of operations presented in accordance with generally accepted accounting principles, but are only a summation of the revenues, cost of services and selling, general and administrative expenses of the individual Founding Companies on a historical basis. The combined results also exclude the effect of pro forma adjustments and may not be comparable to, and may not be indicative of, the Company's post-combination results of operations because (i) the Founding Companies were not under common control or management during the periods presented; (ii) the Founding Companies used different tax structures (S Corporations or C Corporations) during the periods presented; (iii) the Company will incur incremental costs related to its new corporate management and the costs of being a public company; (iv) the Company will use the purchase method to record the Mergers, resulting in the recording of goodwill which will be amortized over 40 years; and (v) the combined data do not reflect the Compensation Differential and potential benefits and cost savings the Company expects to realize when operating as a combined entity. The following table sets forth the combined results of operations of the Founding Companies on a historical basis and such results as a percentage of revenues.

- ------------ (1) The fiscal years presented are as follows: Quality -- the fiscal years ended March 31, 1995 and 1996 and the year ended December 31, 1996; Atlas and Accurate -- the fiscal years ended June 30, 1994 and 1995 and the year ended December 31, 1996; Lawrence -- the fiscal years ended October 31, 1994, 1995 and 1996; and Tri-City, Eastern, CSI/Bonneville,, Tech, Seasonair and Western -- the years ended December 31 for all periods presented. (2) The financial data for 1995 and 1996 both include Quality's results for the three months ended March 31, 1996 which were as follows: revenues of $6.3 million, cost of services of $4.3 million, and selling, general and administrative expenses of $1.6 million. 21 COMBINED RESULTS FOR 1996 COMPARED TO 1995 REVENUES. Combined revenues increased approximately $21.0 million, or 14.3%, from $146.5 million in 1995 to $167.5 million in 1996. The increase in combined revenues occurred primarily at Atlas, Accurate and Lawrence. This increase in combined revenues was primarily attributable to an increase in commercial and industrial "design and build" revenues of approximately 15% and an increase in maintenance, repair and replacement revenues of approximately 30%. Revenues for Atlas increased $7.6 million from 1995 to 1996 due to increasing demand by several large national customers for HVAC "design and build" installation services provided by Atlas for multi-unit facilities. Revenues for Accurate increased $4.6 million from 1995 to 1996 reflecting the success of an increased marketing effort along with the addition of sales personnel and project managers. Revenues at Lawrence increased by $4.6 million from 1995 to 1996 due to a management decision in 1995 to expand the number of general contractors for which Lawrence provides industrial installation services and due to a large "design and build" installation contract obtained in 1996 for a food processing facility. Seven of the other Founding Companies reported an increase in revenues from 1995 and 1996, partially offset by a decline in revenues at Quality and Tri-City. GROSS PROFIT. Combined gross profit increased $6.3 million, or 15.3%, from $41.5 million in 1995 to $47.8 million in 1996, due principally to increases in gross profit of $2.2 million at Atlas, $1.5 million at Lawrence and $1.1 million at Western. As a percentage of revenues, combined gross profit increased from 28.3% in 1995 to 28.5% in 1996. Gross profit as a percentage of revenues at Atlas increased from 12.5% of revenues in 1995 to 16.5% of revenues in 1996 as increasing demand for Atlas' specialized installation services enabled Atlas to earn higher margins. Gross profit as a percentage of revenues at Accurate decreased from 26.1% of revenues in 1995 to 21.0% of revenues in 1996 as a result of an increase in overtime and subcontract labor necessary to support the increased number of "design and build" projects. Gross profit as a percentage of revenues at Western increased from 17.1% to 28.2% from 1995 to 1996, one-half of which resulted from Western's participation in an incentive program sponsored by the Public Service Company of Colorado. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Combined selling, general and administrative expenses increased $3.4 million, or 10.8%, from $31.0 million in 1995 to $34.4 million in 1996. Selling, general and administrative expenses increased $1.4 million at Lawrence, approximately one-half of which was related to increases in salary and incentive compensation paid to the owners, and the other half of which was related to increases in incentive compensation and discretionary profit sharing contributions for employees. Selling, general and administrative expenses increased $0.7 million at Tri-City as a result of a $1.1 million increase in compensation to the owners in lieu of S Corporation distributions, offset by $0.4 million of reductions in other overhead expenses. As a percentage of combined revenues, selling, general and administrative expenses decreased from 21.2% in 1995 to 20.5% in 1996. COMBINED RESULTS FOR 1995 COMPARED TO 1994 REVENUES. Combined revenues increased approximately $21.8 million, or 17.5%, from $124.7 million in 1994 to $146.5 million in 1995, primarily due to an increase in commercial and industrial "design and build" revenues of approximately 40% and an increase of approximately 10% in maintenance, repair and replacement revenues. Revenues at Quality increased $8.2 million from 1994 to 1995 as a result of management's focus on obtaining more "design and build" projects and related service work. Revenues at Tri-City increased $8.1 million from 1994 to 1995 as a result of a strategy implemented in late 1994 to focus on larger "design and build" projects and the related service relationships. To accomplish its strategy, Tri-City increased the size of its sales and project management staff. GROSS PROFIT. Combined gross profit increased $9.1 million, or 28.0%, from $32.4 million in 1994 to $41.5 million in 1995. Gross profit increased $3.1 million at Tri-City and $2.9 million at Quality. As a percentage of revenues, combined gross profit increased from 26.0% in 1994 to 28.3% in 1995. Gross profit as a percentage of revenues at Tri-City increased from 15.5% in 1994 to 22.9% in 1995 as a result of an increase in the number of higher-margin "design and build" installation projects. Gross profit as a percentage of revenues at Lawrence increased from 23.2% in fiscal 1994 to 27.3% in fiscal 1995 as 22 management emphasized higher-margin "design and build" projects and successfully implemented an incentive program for project managers to control project costs. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Combined selling, general and administrative expenses increased $3.6 million, or 13.3%, from $27.4 million in 1994 to $31.0 million in 1995. Selling, general and administrative expenses increased $1.0 million at Tri-City from 1994 to 1995 primarily due to a $0.8 million increase in compensation to its owners. Selling, general and administrative expenses at Lawrence increased $0.6 million primarily due to an increase in salary and incentive compensation to its owners. As a percentage of combined revenues, combined selling, general and administrative expenses decreased from 22.0% in 1994 to 21.2% in 1995. COMBINED LIQUIDITY AND CAPITAL RESOURCES On a combined basis, the Founding Companies generated $9.0 million of net cash from operating activities during fiscal 1996, primarily at Quality, Tri-City and CSI/Bonneville. Net cash used in investing activities was $3.0 million on a combined basis, primarily for equipment purchases. Net cash used in financing activities was $7.3 million on a combined basis, consisting of net reductions in long-term debt of $1.6 million and distributions to stockholders of $5.7 million. At December 31, 1996, the combined Founding Companies had working capital of $18.9 million and total debt of $8.6 million, including debt to stockholders. The Company intends to pursue acquisition opportunities. The Company expects to fund future acquisitions through the issuance of additional Common Stock, borrowings, including use of amounts available under the proposed credit facility and cash flow from operations. The Company anticipates that its cash flow from operations will provide cash in excess of the Company's normal working capital needs, debt service requirements and planned capital expenditures for equipment. On a combined basis, the Founding Companies made capital expenditures of $2.3 million in fiscal 1996. The Company is currently negotiating with a group of banks to obtain a credit facility which would be available upon the closing of the Offering. The Company expects this facility to be a revolving line of credit of at least $50 million. The facility is intended to be used for acquisitions, capital expenditures, refinancing of debt not paid out of the proceeds of this Offering and for general corporate purposes. It is anticipated that such facility will require the Company to comply with various loan covenants including (i) maintenance of certain financial ratios, (ii) restrictions on additional indebtedness, and (iii) restrictions on liens, guarantees, advances and dividends. 23 QUALITY RESULTS OF OPERATIONS Quality, headquartered in Grand Rapids, Michigan, was founded in 1968 and operates primarily throughout western Michigan. Quality focuses on providing "design and build" installation services and maintenance, repair and replacement of HVAC systems, primarily for medium and large commercial facilities.

QUALITY RESULTS FOR NINE MONTHS ENDED DECEMBER 31, 1996 COMPARED TO NINE MONTHS ENDED DECEMBER 31, 1995 REVENUES. Revenues decreased $3.0 million, or 11.4%, from $26.3 million for the nine months ended December 31, 1995 to $23.3 million for the nine months ended December 31, 1996 due to a decrease in Quality's volume of commercial "design and build" installation projects. Quality's decline in revenues from 1995 to 1996 resulted from management's decision to be more selective in accepting installation projects. Management continues to emphasize project selectivity and expansion of capacity through the addition of technical staff and management rather than through subcontract labor and employee overtime. GROSS PROFIT. Gross profit decreased $0.6 million, or 6.3%, from $9.7 million for the nine months ended December 31, 1995 to $9.1 million for the nine months ended December 31, 1996. As a percentage of revenues, gross profit increased from 37.0% to 39.1% due to management's emphasis on project selection and a decrease in the use of subcontract labor, employee overtime and outside services. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses decreased $0.2 million, or 2.9%, from $5.2 million for the nine months ended December 31, 1995 to $5.0 million for the nine months ended December 31, 1996. As a percentage of revenues, these expenses increased from 19.7% to 21.6% due to the decline in revenues. QUALITY RESULTS FOR YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED MARCH 31, 1996 REVENUES. Revenues decreased $3.0 million, or 9.2%, from $32.6 million for the year ended March 31, 1996 to $29.6 million for the year ended December 31, 1996, for the reasons described above. GROSS PROFIT. Gross profit decreased $0.6 million, or 5.2%, from $11.7 million for the year ended March 31, 1996 to $11.1 million for the year ended December 31, 1996. As a percentage of revenues, gross profit increased from 36.0% to 37.6% due to management's emphasis on project selection and a decrease in the use of subcontract labor, employee overtime and outside services. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses decreased $0.2 million, or 2.2%, from $6.8 million for the year ended March 31, 1996 to $6.6 million for the year ended December 31, 1996. As a percentage of revenues, selling, general and administrative expenses increased from 20.8% to 22.4% due to the decline in revenues. 24 QUALITY RESULTS FOR YEAR ENDED MARCH 31, 1996 COMPARED TO YEAR ENDED MARCH 31, 1995 REVENUES. Revenues increased $8.2 million, or 33.4%, from $24.4 million for the fiscal year ended March 31, 1995 to $32.6 for the fiscal year ended March 31, 1996. This increase in revenues was primarily attributable to management's emphasis on obtaining more "design and build" installation projects and the related service work. GROSS PROFIT. Gross profit increased $2.9 million, or 33.5%, from $8.8 million for the fiscal year ended March 31, 1995 to $11.7 million for the fiscal year ended March 31, 1996. As a percentage of revenues, gross profit remained unchanged at 36.0% as the benefits associated with higher revenues were offset by an increase in subcontract labor, employee overtime and outside services. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses increased $0.2 million, or 2.2%, from $6.6 million for the fiscal year ended March 31, 1995 to $6.8 million for the fiscal year ended March 31, 1996. As a percentage of revenues, selling, general and administrative expenses decreased from 27.2% to 20.8% as the Company successfully leveraged its infrastructure to support the significant increase in volume. QUALITY LIQUIDITY AND CAPITAL RESOURCES Quality generated $4.5 million in net cash from operating activities for the twelve months ended December 31, 1996. Net cash used in investing activities was approximately $0.4 million, principally for equipment purchases. Net cash used in financing activities was $4.4 million, of which $3.5 million was distributed to shareholders and $0.9 million was used to repay long-term debt. At December 31, 1996, Quality had working capital of $4.9 million and $1.3 million of total debt outstanding. ATLAS RESULTS OF OPERATIONS Atlas, headquartered in Houston, Texas, was founded in 1947 and operates primarily in the southwest, northeast and mid-Atlantic regions of the United States. Atlas is a leading provider of HVAC installation services for apartment complexes, condominiums, hotels and elder care facilities in the United States and also provides maintenance, repair and replacement of HVAC systems.

Revenues increased $0.8 million, or 5.8%, from $14.7 million for the six months ended December 31, 1995 to $15.5 million for the six months ended December 31, 1996. This increase was primarily attributable to an increase in demand for Atlas' specialized services for multi-unit facilities. GROSS PROFIT. Gross profit increased $1.2 million, or 68.4%, from $1.8 million for the six months ended December 31, 1995 to $3.0 million for the six months ended December 31, 1996. As a percentage of revenues, gross profit increased from 12.3% to 19.5% due to an increase in the proportion of "design and build" projects and management's ability to be more selective in accepting projects. 25 SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses remained unchanged at $1.4 million for the six months ended December 31, 1995 and the six months ended December 31, 1996. As a percentage of revenues, selling, general and administrative expenses decreased from 9.6% to 9.2% as Atlas was able to increase revenues without a commensurate increase in overhead expenses. ATLAS RESULTS FOR YEAR ENDED JUNE 30, 1996 COMPARED TO YEAR ENDED JUNE 30, 1995 REVENUES. Revenues increased $6.8 million, or 30.0%, from $22.4 million for the year ended June 30, 1995 to $29.2 million for the year ended June 30, 1996 due to an increase in demand for Atlas' specialized services for multi-unit facilities. GROSS PROFIT. Gross profit increased $0.9 million, or 32.6%, from $2.8 million for the year ended June 30, 1995 to $3.7 million for the year ended June 30, 1996. As a percentage of revenues, gross profit increased from 12.5% to 12.8%. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses increased $0.6 million, or 31.3%, from $2.2 million for the year ended June 30, 1995 to $2.8 million for the year ended June 30, 1996, as Atlas increased its infrastructure to support higher volume. As a percentage of revenues, selling, general and administrative expenses increased from 9.7% to 9.8%. ATLAS RESULTS FOR JUNE 30, 1995 COMPARED TO YEAR ENDED JUNE 30, 1994 REVENUES. Revenues increased $0.6 million, or 2.7%, from $21.8 million for the year ended June 30, 1994 to $22.4 million for the year ended June 30, 1995. GROSS PROFIT. Gross profit increased $0.6 million, or 28.2%, from $2.2 million for the year ended June 30, 1994 to $2.8 million for the year ended June 30, 1995. As a percentage of revenues, gross profit increased from 10.0% to 12.5%. The increase in the gross profit percentage from 1994 to 1995 was primarily related to higher demand for Atlas' specialized installation services for multi-unit facilities and a decrease in lower-margin "plan and spec" projects. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses increased $0.1 million, or 3.8%, from $2.1 million for the twelve months ended June 30, 1994 to $2.2 million for the twelve months ended June 30, 1995. As a percentage of revenues, selling, general and administrative expenses increased from 9.5% to 9.7%. ATLAS LIQUIDITY AND CAPITAL RESOURCES Atlas used $0.3 million in net cash from operating activities for the twelve months ended June 30, 1996 primarily due to an increase in accounts receivable which were collected in subsequent periods. Net cash used in investing activities was approximately $0.1 million for equipment purchases. Net cash provided by financing activities was $0.3 million for the twelve months ended June 30, 1996, principally as a result of a net increase in long-term debt and notes payable. At December 31, 1996, Atlas had working capital of $2.7 million and total debt of $1.7 million. TRI-CITY RESULTS OF OPERATIONS Tri-City, headquartered in Tempe, Arizona, was founded in 1962 and operates in Arizona, California and Nevada. Tri-City focuses on providing "design and build" installation services and maintenance, repair and replacement of HVAC systems primarily for large commercial and industrial facilities, as well as process piping for industrial facilities. 26 The following table sets forth selected statement of operations data and such data as a percentage of revenues for the periods indicated:

TRI-CITY RESULTS FOR YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995 REVENUES. Revenues decreased $0.8 million, or 3.2%, from $25.0 million in 1995 to $24.2 million in 1996, primarily due to a decrease in "plan and spec" revenues from 1995 to 1996 of approximately $2.0 million, partially offset by an increase of approximately $1.2 million in commercial HVAC maintenance, repair and replacement service revenues. GROSS PROFIT. Gross profit remained constant at $5.7 million for 1995 and 1996. As a percentage of revenues, gross profit increased from 22.9% to 23.4%, due to a decrease in lower margin "plan and spec" projects in 1996. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses increased $0.7 million, or 22.2%, from $3.2 million in 1995 to $3.9 million in 1996 due to a $1.1 million increase in compensation to owners in lieu of S Corporation distributions, offset by a $0.4 million reduction in other overhead expenses. As a percentage of revenues, selling, general and administrative expenses increased from 12.8% in 1995 to 16.1% in 1996, primarily as a result of the increase in owners' compensation. TRI-CITY RESULTS FOR YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994 REVENUES. Revenues increased $8.1 million, or 48.2%, from $16.9 million in 1994 to $25.0 million in 1995 as a result of a strategy implemented in 1994 to emphasize "design and build" projects. To implement its strategy, Tri-City increased its sales and project management staff. GROSS PROFIT. Gross profit increased $3.1 million, or 119.4%, from $2.6 million in 1994 to $5.7 million in 1995. As a percentage of revenues, gross profit increased from 15.5% in 1994 to 22.9% in 1995 as a result of an increase in the proportion of "design and build" installation projects. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses increased $1.0 million, or 43.9%, from $2.2 million in 1994 to $3.2 million in 1995. The increase in selling, general and administrative expenses in 1995 was primarily attributable to a $0.8 million increase in compensation to owners in lieu of S Corporation distributions and an increase in the number of the sales personnel and project managers. As a percentage of revenues, selling, general and administrative expenses decreased from 13.2% in 1994 to 12.8% in 1995 as Tri-City was able to substantially increase its volume without a commensurate increase in overhead expenses. TRI-CITY LIQUIDITY AND CAPITAL RESOURCES Tri-City generated $1.4 million in net cash from operating activities in 1996.

WESTERN RESULTS OF OPERATIONS Western, headquartered in Denver, Colorado, was founded in 1980 and operates primarily in Colorado. Western focuses on providing "design and build" installation services and maintenance, repair and replacement of HVAC systems for commercial facilities. 31 The following table sets forth selected statement of operations data and such data as a percentage of revenues for the periods indicated: YEAR ENDED DECEMBER 31, ---------------------------------------- 1995 1996 ------------------- ------------------- (IN THOUSANDS) Revenues............................. $ 4,112 100.0% $ 6,494 100.0% Cost of services..................... 3,408 82.9 4,662 71.8 -------- --------- --------- -------- Gross profit......................... 704 17.1 1,832 28.2 Selling, general and administrative expenses........................... 855 20.8 1,088 16.7 -------- --------- --------- -------- Income (loss) from operations........ (151) (3.7) 744 11.5 WESTERN RESULTS FOR YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995 REVENUES. Revenues increased $2.4 million, or 57.9%, from $4.1 million in 1995 to $6.5 million in 1996. This increase was primarily attributable to an increase in commercial replacement revenues of $1.5 million related to the Demand Side Management ("DSM") incentive program developed by the Public Service Company of Colorado ("PSC"). This program provided incentives for commercial PSC customers to replace existing HVAC systems with more energy-efficient systems and ended in November 1996. Management believes that a significant portion of the revenues generated under the DSM program can be replaced by redeploying Western's sales force to emphasize installation of commercial control systems and commercial maintenance, repair and replacement services. Western also intends to bid for participation in another PSC incentive program commencing in the second half of 1997. GROSS PROFIT. Gross profit increased $1.1 million, or 160.2%, from $0.7 million in 1995 to $1.8 million in 1996. As a percentage of revenues, gross profit increased from 17.1% in 1995 to 28.2% in 1996, primarily due to an increase in maintenance, repair and replacement revenues, including revenues generated under the DSM program. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and administrative expenses increased $0.2 million in 1995, or 27.3%, from $0.9 million in 1995 to $1.1 million in 1996. As a percentage of revenues, selling, general and administrative expenses decreased from 20.8% to 16.7% as a result of the substantial revenue increase without a commensurate increase in overhead expenses. WESTERN LIQUIDITY AND CAPITAL RESOURCES Western generated $0.6 million in net cash from operating activities in 1996. Net cash used in investing activities was approximately $0.1 million, principally for equipment purchases. Net cash used in financing activities was $0.4 million, as a result of distributions to shareholders and net repayments of long-term debt. Working capital at December 31, 1996 was $0.4 million and total long-term debt outstanding was $0.3 million. SEASONAL AND CYCLICAL NATURE OF THE HVAC INDUSTRY The HVAC industry is subject to seasonal variations. Specifically, the demand for new installations is generally lower during the winter months due to reduced construction activities during inclement weather and less use of air conditioning during the colder months. Demand for HVAC services is generally higher in the second and third quarters due to the increased use of air conditioning during the warmer months. Accordingly, the Company expects its revenues and operating results generally will be lower in the first and fourth quarters. Historically, the construction industry has been highly cyclical. As a result, the Company's volume of business may be adversely affected by declines in new installation projects in various geographic regions of the United States. INFLATION Inflation did not have a significant effect on the results of operations of the combined Founding Companies for 1994, 1995 or 1996. 32 BUSINESS Comfort Systems was founded in 1996 to become a leading national provider of comprehensive HVAC installation services and maintenance, repair and replacement of HVAC systems, focusing primarily on the commercial and industrial markets. The Company's commercial and industrial applications include office buildings, retail centers, apartment complexes, hotels, manufacturing plants and government facilities. The Company also provides specialized HVAC applications such as process cooling, control systems, electronic monitoring and process piping. Approximately 90% of the Company's pro forma combined 1996 revenues of $167.5 million was derived from commercial and industrial customers, with approximately 53% of combined revenues attributable to installation services and 47% attributable to maintenance, repair and replacement services. Combined revenues of the Founding Companies, which have been in business an average of 39 years, increased at a compound annual growth rate of approximately 16% from 1994 through 1996. INDUSTRY OVERVIEW Based on available industry data, the Company believes that the HVAC industry is highly fragmented with over 40,000 companies, most of which are small, owner-operated businesses with limited access to capital for modernization and expansion. The overall HVAC industry, including the commercial, industrial and residential markets, is estimated to generate annual revenues in excess of $75 billion, over $35 billion of which is in the commercial and industrial markets. HVAC systems have become a necessity in virtually all commercial and industrial buildings as well as homes. Because most commercial buildings are sealed, HVAC systems provide the primary method of addressing air quality concerns and injecting fresh air. Older industrial facilities often have poor air quality as well as inadequate air conditioning, factors which are causing industrial facility owners to consider replacement options. Operation of older HVAC systems represents a significant cost due to their energy inefficiency. In many instances, the replacement of an aging system with a modern, energy-efficient system will significantly reduce a building's operating costs while also improving the effectiveness of the HVAC system and air quality. Growth in the HVAC industry is being positively affected by a number of factors, particularly (i) the aging of the installed base, (ii) the increasing efficiency, sophistication and complexity of HVAC systems and (iii) the increasing restrictions on the use of refrigerants commonly used in older HVAC systems. These factors are expected to increase demand for the reconfiguration or replacement of existing HVAC systems. These factors also mitigate the effect on the HVAC industry of the cyclicality inherent in the traditional construction industry. The HVAC industry can be broadly divided into the installation segment and the maintenance, repair and replacement segment. INSTALLATION SEGMENT. The installation segment consists of "design and build" and "plan and spec" projects. In "design and build" projects, the commercial HVAC firm is responsible for designing, engineering and installing a cost-effective, energy-efficient system customized to meet the specific needs of the building owner. Costs and other project terms are normally negotiated between the building owner or its representative and the HVAC firm. Firms which specialize in "design and build" projects generally have specially trained HVAC engineers, CAD/CAM design systems, in-house sheet metal and prefabrication capabilities. These firms utilize a consultative approach with customers and tend to develop long-term relationships with building owners and developers, general contractors, architects and property managers. "Plan and spec" installation refers to projects where an architect or a consulting engineer designs the HVAC system and the installation project is put out for bid. The Company believes that "plan and spec" projects usually take longer to complete than "design and build" projects because the preparation of the system design and the bid process often take months to complete. Furthermore, in "plan and spec" projects, the HVAC firm is not responsible for project design and changes must be approved by several parties, thereby increasing overall project time and cost. MAINTENANCE, REPAIR AND REPLACEMENT SEGMENT. This segment includes the maintenance, repair, replacement, reconfiguration and monitoring of previously installed HVAC systems and controls. Growth in 33 this segment has been fueled by the aging of the installed base of HVAC systems and the increasing demand for more efficient, sophisticated and complex systems and controls. The increasing sophistication and complexity of these HVAC systems is leading many commercial and industrial building owners and property managers to outsource maintenance and repair, often through service agreements with HVAC service providers. In addition, increasing restrictions are being placed on the use of certain types of refrigerants used in HVAC systems, which, along with air quality concerns, are expected to increase demand for the reconfiguration and replacement of existing HVAC systems. State-of-the-art control and monitoring systems feature electronic sensors and microprocessors and require specialized training to install, maintain and repair, which the typical building engineer does not have. Increasingly, HVAC systems in commercial and industrial buildings are being remotely monitored through PC-based communications systems to improve energy efficiency and expedite problem diagnosis and correction. The Company believes that the majority of business owners in the HVAC industry have limited access to capital for expansion of their businesses and that few have attractive liquidity options. In addition, the increasing complexity of HVAC systems has led to a need for better trained technicians to install, monitor and service these systems. The cost of recruiting, training and retaining a sufficient number of qualified technicians makes it more difficult for smaller HVAC companies to expand their businesses. The Company believes that significant opportunities exist for a well-capitalized, national company operating in the commercial, industrial and residential markets of the HVAC industry and that the highly fragmented nature of this industry should allow it to consolidate existing HVAC businesses. STRATEGY The Company plans to achieve its goal of becoming a leading national provider of comprehensive HVAC services by implementing its operating strategy, emphasizing continued internal growth and expanding through acquisitions. OPERATING STRATEGY. The Company believes there are significant opportunities to increase the profitability of the Founding Companies and subsequently acquired businesses. The key elements of the Company's operating strategy are: FOCUS ON COMMERCIAL AND INDUSTRIAL MARKETS. The Company intends to focus principally on the commercial and industrial markets with particular emphasis on the "design and build" installation and the maintenance, repair and replacement segments. The Company believes that the commercial and industrial HVAC markets are attractive because of their growth opportunities, diverse customer base, attractive margins and potential for long-term relationships with building owners and managers, general contractors and architects. OPERATE ON DECENTRALIZED BASIS. The Company intends to manage the Founding Companies on a decentralized basis, with local management assuming responsibility for the day-to-day operations, profitability and growth of the business. The Company believes that, while maintaining strong operating and financial controls, a decentralized operating structure will retain the entrepreneurial spirit present in each of the Founding Companies and will allow the Company to capitalize on the considerable local and regional market knowledge and customer relationships possessed by each Founding Company. ACHIEVE OPERATING EFFICIENCIES. The Company believes there are significant opportunities to achieve operating efficiencies and cost savings through purchasing economies and the adoption of "best practices" operating programs. The Company intends to use its increased purchasing power to gain volume discounts in areas such as HVAC components, raw materials, service vehicles, advertising, bonding and insurance. Moreover, the Company will review its operations and training programs at the local and regional operating levels in order to identify those "best practices" that can be successfully implemented throughout its operations. ATTRACT AND RETAIN QUALITY EMPLOYEES. The Company intends to attract and retain quality employees by providing them (i) an enhanced career path from working for a larger public company, (ii) additional training, education and apprenticeships to allow talented employees to advance to 34 higher-paying positions, (iii) the opportunity to realize a more stable income and (iv) improved benefits packages. INTERNAL GROWTH. A key component of the Company's strategy is to continue the internal growth at the Founding Companies and subsequently acquired businesses. The key elements of the Companys internal growth strategy are: CAPITALIZE ON SPECIALIZED TECHNICAL AND MARKETING STRENGTHS. The Company believes it will be able to expand the services it offers in its markets by leveraging the specialized technical and marketing strengths of individual Founding Companies. For example, one of the Founding Companies has developed significant industry recognition for its technical expertise within apartment complexes, condominiums, hotels and elder care facilities which may be transferable to other Founding Companies. A number of Founding Companies currently focus primarily on installation and, therefore, have only limited maintenance, repair and replacement operations. The Company believes there are significant opportunities for these Founding Companies to provide maintenance, repair and replacement services, particularly by offering those services to its "design and build" customers. Several of the Founding Companies have specific expertise in HVAC control and monitoring systems, process cooling, replacement and other service strengths, many of which can be shared with other Founding Companies and subsequently acquired businesses. ESTABLISH NATIONAL MARKET COVERAGE. The Company believes that significant demand exists from large national companies to utilize the services of a single HVAC service company capable of providing comprehensive commercial and industrial services on a regional or national basis. Many of the Founding Companies already provide local or regional coverage to companies with nationwide locations, such as commercial real estate developers and managers, retailers and manufacturers. The Company believes these existing relationships can be expanded as it develops a nationwide network since these customers often desire a single source for all of their HVAC needs to promote consistency, improve control and reduce cost. ACQUISITIONS. The Company believes the HVAC industry is highly fragmented with over 40,000 companies, most of which are small, owner-operated businesses with limited access to adequate capital for modernization and expansion. The Company anticipates that acquisition candidates in the commercial and industrial markets will typically have annual revenues ranging from $5 million to $35 million. The key elements of the Company's acquisition strategy are: ENTER NEW GEOGRAPHIC MARKETS. In new markets, the Company intends to target one or more leading local or regional companies providing HVAC or complementary services. The acquisition target will have the customer base, technical skills and infrastructure necessary to be a core business into which other HVAC service operations can be consolidated. The Company will choose businesses that are located in attractive markets, are financially stable, are experienced in the industry and have management willing to participate in the future growth of the Company. EXPAND WITHIN EXISTING MARKETS. Once the Company has entered a market, it will seek to acquire other well-established HVAC businesses to expand its market penetration and range of services offered. The Company also will pursue "tuck-in" acquisitions of smaller companies, whose operations can be integrated into an existing Company operation to leverage the existing infrastructure. ACQUIRE COMPLEMENTARY BUSINESSES. The Company will focus on its traditional markets in the HVAC industry and may acquire companies providing complementary services to the same customer base, such as commercial and industrial process piping and plumbing as well as electrical companies. This will enable the Company to offer, on a comprehensive basis and from a single provider, HVAC, mechanical and electrical services in certain markets. ACQUISITION PROGRAM The Company believes it will be regarded by acquisition candidates as an attractive acquiror because of: (i) the Company's strategy for creating a national, comprehensive and professionally managed HVAC 35 service provider that capitalizes on cross-marketing and business development opportunities; (ii) the Company's decentralized operating strategy; (iii) the Company's increased visibility and access to financial resources as a public company; (iv) the potential for increased profitability due to certain centralized administrative functions, enhanced systems capabilities and access to increased marketing resources; and (v) the potential for the owners of the businesses being acquired to participate in the Company's planned internal growth and growth through acquisitions, while realizing liquidity. The Company believes the management teams of the Founding Companies will be instrumental in identifying and completing future acquisitions. The Company's visibility within the HVAC industry will increase the awareness and interest of acquisition candidates in the Company and its acquisition program. Within the past several months, the Company has contacted the owners of a number of acquisition candidates, several of whom have expressed interest in having their business acquired by the Company. The Company currently has no binding agreements to effect any acquisition other than the Founding Companies. As consideration for future acquisitions, the Company intends to use various combinations of its Common Stock, cash and notes. The consideration for each future acquisition will vary on a case-by-case basis. The major factors in establishing the purchase price for each acquisition will be historical operating results, future prospects of the acquiree and the ability of that business to complement the services offered by the Company. Management believes that companies providing commercial and industrial HVAC services are larger than those providing residential services, with commercial and industrial companies generating annual revenues ranging from $5 million to $35 million, compared to companies providing residential HVAC services which generally have annual revenues ranging from $500,000 to $3 million. The Company intends to register 8,000,000 additional shares of Common Stock under the Securities Act for its use in connection with future acquisitions. OPERATIONS AND SERVICES PROVIDED The Company provides a wide range of installation, maintenance, repair and replacement services for HVAC systems in commercial, industrial and residential properties. Daily operations are managed on a local basis by the management team at each Founding Company. In addition to senior management, the Founding Companies' personnel generally include design engineers, sales personnel, customer service personnel, installation service technicians, sheet metal and prefabrication technicians, estimators and administrative personnel. Upon consummation of the Mergers, the Company will manage the Founding Companies on a decentralized basis, with local management being responsible for day-to-day operating decisions. The Company intends to centralize certain administrative functions to enable the management of each Founding Company to focus on pursuing new business opportunities and to improve operating efficiencies. Administrative functions which the Company expects to centralize include Company-wide training and safety programs, accounting programs, risk management programs, purchasing programs and employee benefits. INSTALLATION SEGMENT. The Company's installation business comprised approximately 53% of the Company's 1996 revenues. This segment consists of the design, engineering, integration, installation and start-up of HVAC systems. The commercial and industrial installation services performed by the Company consist primarily of "design and build" systems for office buildings, retail centers, apartment complexes, hotels, manufacturing plants and government facilities. In a "design and build" project, the customer typically has an overall design for the facility prepared by an architect or a consulting engineer who then enlists the Company's sales and engineering personnel to prepare a specific design for the HVAC system. The Company determines the needed capacity, energy efficiency and type of controls that best suit the proposed facility. The Company's engineer then estimates the amount of time, labor, materials and equipment needed to build the specified system. Materials and equipment for a typical commercial or industrial project include ductwork, compressors, blowers, chillers, cooling towers, air handling equipment and the associated pumps and piping necessary to complete the system. The Company utilizes CAD/CAM systems in the design and engineering phases of the project to calculate the material and labor costs of the project based on previously established Company standards and to generate mechanical drawings for each project. The drawings are prepared in a format appropriate for submission to local building inspectors. The 36 final design, terms, price and timing of the project are then negotiated with the customer or its representatives, after which any necessary modifications are made to the system. Once an agreement has been reached, the Company orders the necessary materials and equipment for delivery to meet the project schedule. In most instances, the Company fabricates in its own facilities the ductwork and piping and assembles certain components for the system based on the mechanical drawing specifications, thereby eliminating the need to subcontract ductwork or piping fabrication. The Company's CAD/CAM systems are capable of automatically cutting ductboard, sheet metal and piping, thereby reducing the amount of labor necessary to produce the ductwork and piping for the system. Project specific components are then fabricated at the Company's facilities in sections small enough to be transported to the job site. This enables the Company to limit the amount of field work required for installation, reduce the labor associated with the actual installation process and meet the shorter time requirements increasingly demanded by commercial and industrial customers. The Company installs the system at the project site, working closely with the general contractor. Most commercial and industrial installation projects last from two weeks to one year and generate revenues from $25,000 to $2,000,000 per project. These projects are generally billed periodically as costs are incurred throughout the project, with a 10% retainage until completion and successful start-up of the HVAC system. Atlas, one of the Founding Companies, specializes in the design and installation of HVAC systems for apartment complexes, condominiums, hotels and elder care facilities. Because the room layouts in these types of buildings are typically very similar, Atlas is able to design a single HVAC system, or a few systems, suitable for installation in all units within the project. This permits Atlas to prepare a "kit" containing all parts for an individual unit and ship all of the kits for a particular project to the job site, thereby significantly decreasing installation time. The Company also performs selected "plan and spec" installation services when a bidder prequalification process has been used by the customer to limit the number of potential bidders for an attractive project. The Company may use these projects when "design and build" projects are in lower demand and to provide additional on-the-job training to apprentice or less-experienced technicians. The Company also installs process cooling systems, control and monitoring systems and industrial process piping. Process cooling systems are utilized primarily in industrial facilities to provide heating and/or cooling to precise temperature and climate standards for products being manufactured and for the manufacturing equipment. Control systems are used in HVAC and process cooling systems in order to maintain pre-established temperature or climate standards for commercial or industrial facilities. These systems use direct digital technology integrated with computer terminals. HVAC control systems are capable not only of controlling a facility's entire HVAC system, often on a room-by-room basis, but can be programmed to integrate energy management, security, fire, card key access, lighting and overall facility monitoring. Monitoring can be performed on-site or remotely through a PC-based communications system. The monitoring system will sound an alarm when the HVAC system is operating outside pre-established parameters. Diagnosis of potential problems can be performed from the computer terminal which often can remotely adjust the control system. Industrial process piping is utilized in manufacturing facilities to convey required raw materials, support utilities and finished products. The Company's residential services consist of installing complete central HVAC systems in new and existing homes, often through agreements with housing developers. In 1996, residential installation comprised approximately 2% of the Company's revenues. The Founding Companies generally warrant their labor for the first year after installation on new HVAC systems and for 30 days after servicing of existing HVAC systems. A reserve for warranty costs is recorded based on a percentage of material costs. MAINTENANCE, REPAIR AND REPLACEMENT SEGMENT. The Company's maintenance, repair and replacement segment comprised approximately 47% of the Company's 1996 combined revenues and includes the maintenance, repair, replacement, reconfiguration and monitoring of HVAC systems and industrial process piping. Over one-half of the Company's maintenance, repair and replacement segment revenues were 37 derived from reconfiguring existing HVAC systems for commercial and industrial customers. Reconfiguration often utilizes consultative expertise similar to that provided in the "design and build" installation market. The Company believes that the reconfiguration of an existing system results in a more cost-effective, energy-efficient system that better meets the specific needs of the building owner. The reconfiguration also enables the Company to utilize its design and engineering personnel as well as its sheet metal and pre-fabrication facilities. Maintenance and repair services are provided either in response to service calls or pursuant to a service agreement. Service calls are coordinated by customer service representatives or dispatchers that use computer and communications technology to process orders, arrange service calls, communicate with customers, dispatch technicians and invoice customers. Service technicians work out of service vans equipped with commonly used parts, supplies and tools to complete a variety of jobs. Commercial and industrial service agreements usually have terms of one to three years, with automatic annual renewals, and typically provide fees from $3,000 to $20,000 per year. The Company also provides remote monitoring of temperature, pressure, humidity and air flow for HVAC systems for commercial and industrial customers. If the system is not operating within the specifications set forth by the customer and cannot be remotely adjusted, a service crew is dispatched to analyze and repair the system, as appropriate. Residential service agreements generally have one year terms, automatic renewal provisions and provide annual fees between $100 and $200. SOURCES OF SUPPLY The raw materials and components used by the Company include HVAC system components, ductwork, steel, sheet metal and copper tubing and piping. These raw materials and components are generally available from a variety of domestic or foreign suppliers at competitive prices. Delivery times are typically short for most raw materials and standard components, but during periods of peak demand may take a month or more to obtain. Chillers for large units typically have the longest delivery time and generally have lead times of up to six months. The major components of HVAC systems are compressors and chillers that are manufactured primarily by York Heating and Air Conditioning Corporation ("York"), Carrier Corporation and Trane Air Conditioning Company. The major suppliers of control systems are Honeywell Inc., Johnson Controls Inc., York and Andover Control Corporation. The Company believes that it will be able to reduce costs on raw materials and components through volume purchases. The Company does not currently have any significant contracts for the supply of raw materials or components. SALES AND MARKETING The Company has a diverse customer base, with no single customer accounting for more than 4% of the Company's pro forma combined 1996 revenues. Management and a dedicated sales force at the Founding Companies have been responsible for developing and maintaining successful long-term relationships with key customers. Customers of the Founding Companies generally include building owners and developers and property managers, as well as general contractors, architects and consulting engineers. The Company intends to continue its emphasis on developing and maintaining long-term relationships with its customers by providing superior, high-quality service in a professional manner. Moreover, the dedicated sales force will receive additional technical and sales training to enhance the comprehensive selling skills necessary to serve the HVAC needs of its customers. The Company also intends to capitalize on cross-marketing and business development opportunities that management believes will be available to the Company as a national provider of comprehensive commercial, industrial and residential HVAC services. Management believes that it will be able to leverage the diverse technical and marketing strengths of individual Founding Companies to expand the services offered in other local markets. Eventually, the Company intends to offer comprehensive services from many of its regional locations. 38 EMPLOYEES As of December 31, 1996, the Company had 1,426 employees, including 74 management personnel, 1,126 engineers and service and installation technicians, 71 sales personnel and 155 administrative personnel. The Company does not anticipate any reductions in staff as a result of the consolidation of the Founding Companies. Rather, as it implements its internal growth and acquisition strategies, the Company expects that the number of employees will increase. Three of the Founding Companies have collective bargaining agreements which cover, in the aggregate, fewer than 50 employees. Under these agreements, these Founding Companies make payments to multi-employer pension plans. The Company has not experienced any strikes or work stoppages and believes its relationship with its employees and union representatives is satisfactory. RECRUITING, TRAINING AND SAFETY The Company's future success will depend, in part, on its ability to continue to attract, retain and motivate qualified service technicians, field supervisors and project managers. The Company believes that its success in retaining qualified employees will be based on the quality of its recruiting, training, compensation, employee benefits programs and opportunities for advancement. The Company recruits at local technical schools and community colleges where students focus on learning basic HVAC and related skills, and provides on-the-job training, apprenticeship programs, improved benefit packages, steady employment and opportunities for advancement. The Company intends to establish "best practices" throughout its operations to ensure that all technicians comply with safety standards established by the Company, its insurance carriers and federal, state and local laws and regulations. The Company's employment screening process seeks to determine that prospective employees have the requisite skills, sufficient background references and acceptable driving records, if applicable. The Company believes that these employment criteria effectively identify potential employees committed to safety and quality. Additionally, the Company intends to implement a "best practices" safety program throughout its operations, which will provide employees with incentives to improve safety performance and decrease workplace accidents. The Company intends to implement job site safety meetings and instruct personnel in proper lifting techniques and eye safety in an effort to reduce the number of preventable accidents. FACILITIES AND VEHICLES All of the Company's facilities will be leased. Prior to the Mergers, Accurate owned the building it uses for its offices and operations. As part of the agreement pursuant to which Accurate is being acquired, it will transfer ownership of that building to its stockholder who will enter into a long-term lease of the building to the Company. See "Certain Transactions -- Leases of Real Property by Founding Companies." The Founding Companies collectively lease approximately 250,000 square feet of commercial property, which they utilize for office, warehouse, fabrication and storage space. Leased premises range in size from 50,200 square feet, in the case of Quality, to 7,000 square feet and 6,500 square feet in the case of Eastern and Seasonair, respectively. In addition, Atlas currently leases 14 one-bedroom apartments for technicians and installation crews working on projects around the country. After consummation of the Mergers, the Company believes that the opportunities for some of the Founding Companies to use fabrication and storage facilities of other Founding Companies for sheet metal cutting, equipment fabrication and inventory storage will increase operating efficiencies for the Company as a whole. The Company operates a fleet of approximately 600 owned or leased service trucks, vans and support vehicles. It believes these vehicles generally are well-maintained and adequate for the Company's current operations. The Company expects it will be able to purchase vehicles at lower prices due to its increased purchasing volume. After the consummation of this Offering, the Company will lease its principal executive and administrative offices in Houston, Texas and is currently in the process of obtaining office space for this purpose. 39 RISK MANAGEMENT, INSURANCE AND LITIGATION The primary risks in the Company's operations are bodily injury, property damage and injured workers' compensation. Upon completion of the Offering, the Company intends to obtain and maintain liability insurance for bodily injury and third party property damage which it considers sufficient to insure against these risks, subject to self-insured amounts. The workers' compensation insurance policies held by the Founding Companies generally provide for first dollar coverage. The Company is, from time to time, a party to litigation arising in the normal course of its business, most of which involves claims for personal injury and property damage incurred in connection with its operations. The Company is not currently involved in any litigation the Company believes will have a material adverse effect on its financial condition or results of operations. COMPETITION The HVAC industry is highly competitive. The Company believes that purchasing decisions in the commercial and industrial markets are based on (i) long-term customer relationships, (ii) quality, timeliness and reliability of services provided, (iii) competitive price, (iv) range of services provided, and (v) scale of operation. The Company believes its strategy of becoming a leading national provider of comprehensive HVAC installation services as well as maintenance, repair and replacement of HVAC systems directly addresses these factors. Specifically, the Company's strategy to focus on the highly consultative "design and build" installation segment and the maintenance, repair and replacement segment, as well as its strategy to operate on a decentralized basis, should promote the development and strengthening of long-term customer relationships. In addition, the Company's focus on attracting, training and retaining quality employees by utilizing professionally managed recruiting, training and benefits programs should allow it to offer high quality, comprehensive HVAC services at a competitive price. Most of the Company's competitors are small, owner-operated companies that typically operate in a limited geographic area. There are a few public companies focused on providing HVAC services in some of the same services lines provided by the Company. In addition, there are a number of private companies attempting to consolidate HVAC companies on a regional or national basis. In the future, competition may be encountered from new entrants, such as public utilities and HVAC manufacturers. Certain of the Company's competitors and potential competitors may have greater financial resources than the Company to finance acquisition and development opportunities, to pay higher prices for the same opportunities or to develop and support their own operations. GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS The Company's operations are subject to various federal, state and local laws and regulations, including, (i) licensing requirements applicable to service technicians, (ii) building and HVAC codes and zoning ordinances, (iii) regulations relating to consumer protection, including those governing residential service agreements and (iv) regulations relating to worker safety and protection of the environment. The Company believes it has all required licenses to conduct its operations and is in substantial compliance with applicable regulatory requirements. Failure of the Company to comply with applicable regulations could result in substantial fines or revocation of the Company's operating licenses. Many state and local regulations governing the HVAC services trades require permits and licenses to be held by individuals. In some cases, a required permit or license held by a single individual may be sufficient to authorize specified activities for all the Company's service technicians who work in the state or county that issued the permit or license. The Company intends to implement a policy to ensure that, where possible, any such permits or licenses that may be material to the Company's operations in a particular geographic region are held by at least two Company employees within that region. The Company's operations are subject to the federal Clean Air Act, as amended (the "Clean Air Act"), which governs air emissions and imposes specific requirements on the use and handling of chlorofluorocarbons ("CFCs") and certain other refrigerants. Clean Air Act regulations require the certification of service technicians involved in the service or repair of equipment containing these 40 refrigerants and also regulate the containment and recycling of these refrigerants. These requirements have increased the Company's training expenses and expenditures for containment and recycling equipment. The Clean Air Act is intended ultimately to eliminate the use of CFCs in the United States and to require alternative refrigerants to be used in replacement HVAC systems. As a result, the number of conversions of existing HVAC systems which use CFCs to systems using alternative refrigerants is expected to increase. Prior to entering into the agreements relating to the Mergers, the Company evaluated the properties owned or leased by the Founding Companies and engaged an independent environmental consulting firm to conduct or review assessments of environmental conditions at these properties. No material environmental problems were discovered in these reviews, and the Company is not aware of any material environmental liabilities associated with these properties. 41 MANAGEMENT DIRECTORS AND EXECUTIVE OFFICERS The following table sets forth information concerning the Company's directors, executive officers and key employees upon completion of this Offering.

EXECUTIVE COMPENSATION; EMPLOYMENT AGREEMENTS; COVENANTS-NOT-TO-COMPETE The Company was incorporated in December 1996, has conducted limited operations and generated no revenue to date and did not pay any of its executive officers compensation during 1996. The Company anticipates that during 1997 its five most highly compensated executive officers will be Messrs. Ferreira, Beittenmiller, George, Nothum and Powers. Each of Messrs. Ferreira, Beittenmiller and George will enter into an employment agreement upon consummation of this Offering with the Company providing for an annual base salary of $150,000. Each employment agreement will be for a term of three years, and unless terminated or not renewed by the Company or not renewed by the employee, the term will continue thereafter on a year-to-year basis on the same terms and conditions existing at the time of renewal. Each of these agreements will provide that, in the event of a termination of employment by the Company without cause, the employee will be entitled to receive from the Company an amount equal to one year's salary, payable in one lump sum on the effective date of termination. In the event of a change in control of the Company (as defined in the agreement) during the initial three-year term, if the employee is not given at least five days' notice of such change in control, the employee may elect to terminate his employment and receive in one lump sum three times the amount he would receive pursuant to a termination without cause during such initial term. The non-competition provisions of the employment agreement do not apply to a termination without such notice. In the event the employee is given at least five days' notice of such change in control, the employee may elect to terminate his employment and receive in one lump sum three times the amount he would receive pursuant to a termination without cause during such initial term. In such event, the non-competition provisions of the employment agreement would apply for two years from the effective date of termination. Each employment agreement contains a covenant not to compete with the Company for a period of two years immediately following termination of employment or, in the case of a termination by the Company without cause in the absence of a change in control, for a period of one year following termination of employment. Each of Messrs. Nothum and Powers will enter into an employment agreement with their respective Founding Company providing for an annual base salary of $150,000. Each employment agreement will be for a term of five years, and unless terminated or not renewed by the Founding Company or not renewed by the employee, the term will continue thereafter on a year-to-year basis on the same terms and conditions existing at the time of renewal. Each of these agreements will provide that, in the event of a termination of employment by the Founding Company without cause during the first three years of the employment term (the "Initial Term"), the employee will be entitled to receive from the Founding Company an amount equal to his then current salary for the remainder of the Initial Term or for one year, whichever is greater. In the event of a termination of employment with cause during the final two years of the initial five year term of the employment agreement, the employee will be entitled to receive an amount equal to his then current salary for one year. In either case, payment is due in one lump sum on the effective date of termination. In the event of a change in control of the Company (as defined in the agreement) during the Initial Term, if the employee is not given at least five days' notice of such change in control, the employee may elect to terminate his employment and receive in one lump sum three times the amount he would receive pursuant to a termination without cause during the Initial Term. The non-competition provisions of the employment agreement do not apply to a termination without such notice. In the event the employee is given at least five days' notice of such change in control, the employee may elect to terminate his employment agreement and receive in one lump sum two times the amount he would receive pursuant to a termination without cause during the Initial Term. In such event, the non-competition provisions of the employment agreement would 45 apply for two years from the effective date of termination. Each employment agreement contains a covenant not to compete with the Company for a period of two years immediately following termination of employment or, in the case of a termination by the Company without cause in the absence of a change in control, for a period of one year following termination of employment. At least one principal executive officer of each of the other Founding Companies will enter into an employment agreement, containing substantially the same provisions, including a covenant not to compete, as Messrs. Nothum's and Power's employment agreements. 1997 LONG-TERM INCENTIVE PLAN No stock options were granted to, or exercised by or held by any executive officer in 1996. In March 1997, the Board of Directors and the Company's stockholders approved the Company's 1997 Long-Term Incentive Plan (the "Plan"). The purpose of the Plan is to provide directors, officers, key employees, consultants and other service providers with additional incentives by increasing their ownership interests in the Company. Individual awards under the Plan may take the form of one or more of: (i) either incentive stock options ("ISOs") or non-qualified stock options ("NQSOs"), (ii) stock appreciation rights ("SARs"), (iii) restricted or deferred stock, (iv) dividend equivalents and (v) other awards not otherwise provided for, the value of which is based in whole or in part upon the value of the Common Stock. The Compensation Committee will administer the Plan and select the individuals who will receive awards and establish the terms and conditions of those awards. The maximum number of shares of Common Stock that may be subject to outstanding awards, determined immediately after the grant of any award, may not exceed the greater of 2,500,000 shares or 13% of the aggregate number of shares of Common Stock outstanding. Shares of Common Stock which are attributable to awards which have expired, terminated or been canceled or forfeited are available for issuance or use in connection with future awards. The Plan will remain in effect until terminated by the Board of Directors. The Plan may be amended by the Board of Directors without the consent of the stockholders of the Company, except that any amendment, although effective when made, will be subject to stockholder approval if required by any Federal or state law or regulation or by the rules of any stock exchange or automated quotation system on which the Common Stock may then be listed or quoted. At the closing of this Offering, NQSOs to purchase a total of 675,000 shares of Common Stock will be granted as follows: 200,000 shares to Mr. Ferreira, 100,000 shares to Mr. Beittenmiller, 100,000 shares to Mr. Busbee, 100,000 shares to Mr. Lemmon, 75,000 shares to Mr. George, 50,000 shares to Mr. Honeycutt and 50,000 shares to Mr. Vensel. In addition, at the closing of this Offering, options to purchase 1,271,954 shares will be granted to certain employees of the Founding Companies. Each of the foregoing options will have an exercise price equal to the initial public offering price per share. These options will vest at the rate of 20% per year, commencing on the first anniversary of this Offering and will expire at the earlier of seven years from the date of grant or three months following termination of employment. 1997 NON-EMPLOYEE DIRECTORS' STOCK PLAN The Company's 1997 Non-Employee Directors' Stock Plan (the "Directors' Plan"), which was adopted by the Board of Directors and approved by the Company's stockholders in March 1997, provides for (i) the automatic grant to each non-employee director serving at the commencement of this Offering of an option to purchase 10,000 shares, (ii) the automatic grant to each non-employee director of an option to purchase 10,000 shares upon such person's initial election as a director and (iii) an automatic annual grant to each non-employee director of an option to purchase 5,000 shares at each annual meeting of stockholders thereafter at which such director is re-elected or remains a director, unless such annual meeting is held within three months of such person's initial election as a director. All options will have an exercise price per share equal to the fair market value of the Common Stock on the date of grant and are immediately vested and expire on the earlier of ten years from the date of grant or one year after termination of service as a director. The Directors' Plan also permits non-employee directors to elect to receive, in lieu of cash directors' fees, shares or credits representing "deferred shares" at future settlement dates, as selected by the director. The number of shares or deferred shares received will equal the number of shares of Common Stock which, at the date the fees would otherwise be payable, will have an aggregate fair market value equal to the amount of such fees. 46 CERTAIN TRANSACTIONS ORGANIZATION OF THE COMPANY In connection with the formation of Comfort Systems, Comfort Systems issued to Notre a total of 2,969,912 shares of Common Stock for an aggregate cash consideration of $29,699. Mr. Harter is the President of Notre and a director of the Company. In March 1997, Notre exchanged its 2,969,912 shares of Common Stock for an equal number of shares of Restricted Common Stock. On the consummation of this Offering, a portion of the Restricted Common Stock will convert automatically into Common Stock. See "Description of Capital Stock." Notre has agreed to advance whatever funds are necessary to effect the Mergers and this Offering. As of March 26, 1997, Notre had outstanding advances to the Company in the aggregate amount of approximately $825,000, all of which is on a non-interest-bearing basis.

In addition, immediately prior to the Mergers certain of the Founding Companies will make the S Corporation Distributions of $16.6 million, and the Interim Earnings Distributions. Also, prior to the Mergers, Accurate will distribute to Thomas Beaty real property having a net book value of approximately $370,000.

These conditions include, among others, the continuing accuracy on the closing date of the Mergers of the representations and warranties of the Founding Companies and the principal stockholders thereof and of Comfort Systems, the performance by each of them of all covenants included in the agreements relating to the Mergers and the nonexistence of a material adverse change in the results of operations, financial condition or business of each Founding Company. There can be no assurance that the conditions to closing of the Mergers will be satisfied or waived or that the acquisition agreements will not be terminated prior to consummation. If any of the Mergers is terminated for any reason, the Company does not intend to consummate this Offering on the terms described herein. 47 The following table sets forth the consideration to be paid by Comfort Systems for each of the Founding Companies: SHARES OF COMMON CASH STOCK --------- ----------- (DOLLARS IN THOUSANDS) Quality.............................. $ 10,082 2,207,158 Tri-City............................. 8,680 1,557,962 Atlas................................ 6,864 1,432,000 Lawrence............................. 4,500 1,197,796 Tech................................. 3,997 717,408 Accurate............................. 3,145 564,537 CSI/Bonneville....................... 1,813 493,672 Western.............................. 2,022 362,939 Freeway.............................. 1,039 319,698 Seasonair............................ 1,516 272,084 Standard............................. 947 291,457 Eastern.............................. 698 304,216 --------- ----------- Total...................... $ 45,303 9,720,927 ========= =========== In connection with the Mergers, and as consideration for their interests in the Founding Companies, certain officers, directors, key employees and holders of more than 5% of the outstanding shares of the Company, together with their spouses and trusts for which they act as trustees, will receive cash and shares of Common Stock of the Company as follows: SHARES OF COMMON NAME CASH STOCK - ------------------------------------- --------- ----------- (DOLLARS IN THOUSANDS) Robert J.

Certain of the Founding Companies have incurred indebtedness which has been personally guaranteed by their stockholders or by entities controlled by its stockholders. At December 31, 1996, the aggregate amount of indebtedness of these Founding Companies that was subject to personal guarantees was approximately $2.8 million. The Company intends to use its best efforts to have the personal guarantees of this indebtedness released within 60 days after the closing of this Offering and, in the event that any guarantee cannot be released, to repay such indebtedness. See "Use of Proceeds." 48 LEASES OF REAL PROPERTY BY FOUNDING COMPANIES Following the Mergers, Atlas will continue to lease its office space in Houston, Texas, as well as mobile homes located in Austin, Texas; Phoenix, Arizona; and Antioch, Tennessee. These properties are owned by M & B Interests, Inc., a corporation wholly-owned by Mr. Brian Atlas, who will become a director of the Company upon consummation of this Offering, and Mr. Michael Atlas ("M & B"). The lease for the real property in Houston expires on September 30, 1997 and provides for an annual rental of $90,000. The three single family residences are leased on a month-to-month basis, at an annual aggregate rental of $36,780. In March 1997, Atlas entered into an agreement with M & B to lease a newly constructed office and warehouse facility to be constructed by M & B in Houston for an annual rental of $204,000. When construction is completed, this new office and warehouse facility will replace Atlas' existing facility. The Company believes that the rent for these properties does not exceed fair market value. Following the Mergers, Tri-City will continue to lease its office space in Tempe, Arizona from Mr. Nothum, Jr. and his father. Mr. Nothum, Jr. is a trustee of a family trust that is a stockholder of Tri-City and will become a director of the Company upon consummation of this Offering.

Additionally, Tri-City provides liability insurance on the property and is responsible for any increases in real property taxes due to its improvement of the leased property. Tri-City has a verbal commitment with a limited liability corporation owned by Mr. Nothum, Jr. and his father to construct new office, operations and warehouse facilities. The Company believes that the rent for these properties does not and will not exceed fair market value.

The other leased premise is used by Accurate as a sheet metal shop under a lease that expires on May 31, 2002 and provides for an annual rental of $72,000. The rental rate on these premises in subsequent years of the lease term will be adjusted in accordance with the Consumer Price Index (the "CPI"). Additionally, Accurate will pay all utility, taxes and insurance costs on both leased premises. Accurate has options to renew each lease for two additional five-year terms. The Company believes that the rent for both properties does not exceed fair market value. Accurate previously owned the property it uses for its sheet metal shop. Prior to the Mergers, Accurate will distribute this property having a net book value of approximately $370,000 to Mr. Beaty and his wife. Following the Mergers, Eastern will continue to lease its office and warehouse space in Albany, New York, owned by 60 Loudonville Road Associates ("Loudonville"), a partnership of Mr. Alfred J.

The Company believes that the rent for this property does not exceed the fair market value thereof. The lease expires on December 31, 1999. Prior to expiration, however, Eastern intends to enter into a 10-year lease with Loudonville for a new building and terminate the existing lease. Eastern has agreed to install the HVAC systems in the new building at a price which the Company believes to be at a fair market value. The Company's annual rental in the new building will be at fair market value, as determined by an appraisal. Following the Mergers, CSI/Bonneville will continue to lease its office and warehouse space in Salt Lake Valley, Utah from J & J Investments, a joint venture partly owned by Mr. Phillips, who will become a 49 director of the Company upon consummation of this Offering.

Tech is responsible for its utility costs, 15% of common utility costs and 50% of the landlord's cost of servicing and maintaining the premises and providing comprehensive liability insurance for the leased premises. The Company believes that the rent for such property does not exceed fair market value. Following the Mergers, Quality will continue to lease its warehouse facility in Grand Rapids, Michigan from Mr. Powers, who will become a director of the Company upon consummation of this Offering. Construction of the warehouse facility was financed with the proceeds of a public bond issue. The lease expires on April 30, 2005, and provides for an annual rental of the greater of $216,000 or Mr. Powers' costs for the leased warehouse, including bond debt service or mortgage payments, utilities, insurance, ad valorem taxes, maintenance and repairs. Quality has an option to renew the lease for one additional three-year term on the same terms. The Company believes that the rent for such property does not exceed fair market value. Quality has guaranteed the payment of two series of public bonds issued in 1985 and 1990, respectively, by the Michigan Strategic Fund on behalf of two real property development entities owned by Mr. Powers, the proceeds of which were used to fund the construction of Quality's leased warehouse facility and a second adjacent warehouse. As of March 1997, approximately $1.6 million of the bond debt remained outstanding. The Company has adopted a policy that, whenever possible, it will not own any real estate. Accordingly, in connection with future acquisitions, the Company may require the distribution of real property owned by acquired companies to its stockholders and the leaseback of such property at fair market value.

Mr. Harter is the President of Notre. (2) Includes 10,000 shares of Common Stock which may be issued upon exercise of options granted under the Directors' Plan. (3) Includes 7,692 shares of Common Stock issuable on conversion of a convertible note issued by Notre which is convertible into Common Stock of the Company owned by Notre. 52 DESCRIPTION OF CAPITAL STOCK GENERAL The authorized capital stock of the Company consists of 57,969,912 shares of capital stock, consisting of 50,000,000 shares of Common Stock, 2,969,912 shares of Restricted Common Stock and 5,000,000 shares of Preferred Stock. Upon completion of the Mergers and this Offering, the Company will have outstanding 20,060,774 shares of Common Stock, which includes 2,969,912 shares of Restricted Common Stock (all of which are owned by Notre) and no shares of Preferred Stock. The following discussion is qualified in its entirety by reference to the Restated Certificate of Incorporation of Comfort Systems, which is included as an exhibit to the Registration Statement of which this Prospectus is a part. COMMON STOCK AND RESTRICTED COMMON STOCK The holders of Common Stock are each entitled to one vote for each share held on all matters to which they are entitled to vote, including the election of directors. The holders of Restricted Common Stock, voting together as a single class, are entitled to elect one member of the Company's Board of Directors and to one-half of one vote for each share held on all other matters which they are entitled to vote including the election of all other directors. Upon consummation of this Offering, the Board of Directors will be classified into three classes as nearly equal in number as possible, with the term of each class expiring on a staggered basis. The classification of the Board of Directors may make it more difficult to change the composition of the Board of Directors and thereby may discourage or make more difficult an attempt by a person or group to obtain control of the Company. Cumulative voting for the election of directors is not permitted. Any director, or the entire Board of Directors, may be removed at any time, with cause, by of a majority of the aggregate number of votes which may be cast by the holders of all of the outstanding shares of Common Stock and Restricted Common Stock entitled to vote for the election of directors, except that only the holder of the Restricted Common Stock may remove the director such holder is entitled to elect. Subject to the rights of any then outstanding shares of Preferred Stock, holders of Common Stock and Restricted Voting Common Stock are together entitled to participate pro rata in such dividends as may be declared in the discretion of the Board of Directors out of funds legally available therefor. Holders of Common Stock and Restricted Common Stock together are entitled to share ratably in the net assets of the Company upon liquidation after payment or provision for all liabilities and any preferential liquidation rights of any Preferred Stock then outstanding. Holders of Common Stock and holders of Restricted Common Stock have no preemptive rights to purchase shares of stock of the Company. Shares of Common Stock are not subject to any redemption provisions and are not convertible into any other securities of the Company. Shares of Restricted Common Stock are not subject to any redemption provisions and are convertible into Common Stock as described below. All outstanding shares of Common Stock and Restricted Common Stock are, and the shares of Common Stock to be issued pursuant to this Offering and the Mergers will be, upon payment therefor, fully paid and non-assessable. Each share of Restricted Common Stock will automatically convert to Common Stock on a share for share basis (i) in the event of a disposition of such share of Restricted Common Stock by Notre, (ii) in the event any person acquires beneficial ownership of 15% or more of the total number of outstanding shares of Common Stock, (iii) in the event any person offers to acquire 15% or more of the total number of outstanding shares of Common Stock, (iv) at any time after the second anniversary of this Offering, at the election of Notre, (v) on the fifth anniversary of the date of this Prospectus or (vi) earlier, upon the affirmative vote of a majority of the aggregate number of votes which may be cast by the holders of the total number of outstanding shares of Common Stock and Restricted Common Stock. Following exercise or expiration of the Underwriters' over-allotment option, a number of shares of Restricted Common Stock will be automatically converted to shares of Common Stock so that the aggregate number of votes attributable to (i) the shares of Common Stock issued and outstanding prior to this Offering (excluding shares issued in the Mergers), (ii) the shares of Common Stock issuable on conversion of such shares of Restricted Common Stock, and (iii) unconverted shares of Restricted Common Stock, equals 19.9% of the aggregate number of votes attributable to all shares of Common Stock and Restricted Common Stock outstanding immediately 53 following the exercise or expiration of the Underwriters' over-allotment option. After July 1, 1998, the Board of Directors may elect to convert any remaining shares of Restricted Common Stock into shares of Common Stock in the event 80% or more of the originally outstanding shares of Restricted Common Stock have been previously converted into shares of Common Stock. The Common Stock has been approved for listing on The New York Stock Exchange under the symbol " ," subject to official notice of issuance. The Restricted Common Stock will not be listed on any exchange. PREFERRED STOCK The Preferred Stock may be issued from time to time by the Board of Directors in one or more series. Subject to the provisions of the Company's Certificate of Incorporation and limitations prescribed by law, the Board of Directors is expressly authorized to adopt resolutions to issue the shares, to fix the number of shares and to change the number of shares constituting any series and to provide for or change the voting powers, designations, preferences and relative, participating, optional or other special rights, qualifications, limitations or restrictions thereof, including dividend rights (including whether dividends are cumulative), dividend rates, terms of redemption (including sinking fund provisions), redemption prices, conversion rights and liquidation preferences of the shares constituting any series of the Preferred Stock, in each case without any further action or vote by the stockholders. The Company has no current plans to issue any shares of Preferred Stock. One of the effects of undesignated Preferred Stock may be to enable the Board of Directors to render more difficult or to discourage an attempt to obtain control of the Company by means of a tender offer, proxy contest, merger or otherwise, and thereby to protect the continuity of the Company's management. The issuance of shares of the Preferred Stock pursuant to the Board of Directors' authority described above may adversely affect the rights of the holders of Common Stock. For example, Preferred Stock issued by the Company may rank prior to the Common Stock and Restricted Common Stock as to dividend rights, liquidation preference or both, may have full or limited voting rights and may be convertible into shares of Common Stock. Accordingly, the issuance of shares of Preferred Stock may discourage bids for the Common Stock or may otherwise adversely affect the market price of the Common Stock. STATUTORY BUSINESS COMBINATION PROVISION The Company is subject to Section 203 of the DGCL which, with certain exceptions, prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any "interested stockholder" for a period of three years following the date that such stockholder became an interested stockholder, unless: (i) prior to such date, the Board of Directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder, (ii) upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned (a) by persons who are directors and officers and (b) by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer, or (iii) on or after such date, the business combination is approved by the Board of Directors and authorized at an annual or special meeting of stockholders by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder. An "interested stockholder" is defined as any person that is (a) the owner of 15% or more of the outstanding voting stock of the corporation or (b) an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within the three-year period immediately prior to the date on which it is sought to be determined whether such person is an interested stockholder. 54 CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BYLAWS Pursuant to the Company's Certificate of Incorporation and as permitted by Delaware law, directors of the Company are not liable to the Company or its stockholders for monetary damages for breach of fiduciary duty, except for liability in connection with a breach of duty of loyalty, for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, for dividend payments or stock repurchases illegal under Delaware law or any transaction in which a director has derived an improper personal benefit. Additionally, the Certificate of Incorporation of the Company provides that directors and officers of the Company shall be, and at the discretion of the Board of Directors non-officer employees and agents may be, indemnified by the Company to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended, against all expenses and liabilities actually and reasonably incurred in connection with service for or on behalf of the Company, and further permits the advancing of expenses incurred in defense of claims. The Certificate of Incorporation also provides that any action required or permitted to be taken by the stockholders of the Company at an annual or special meeting of stockholders must be effected at a duly called meeting and may not be taken or effected by a written consent of stockholders in lieu thereof. The Company's Bylaws provide that a special meeting of stockholders may be called only by the Chief Executive Officer, by a majority of the Board of Directors, or by a majority of the Executive Committee of the Board of Directors. The Bylaws provide that only those matters set forth in the notice of the special meeting may be considered or acted upon at that special meeting. To amend or repeal the Company's Bylaws, an amendment or repeal thereof must first be approved by the Board of Directors or by affirmative vote of the holders of at least 66 2/3% of the total votes eligible to be cast by holders of voting stock with respect to such amendment or repeal. The Company's Bylaws establish an advance notice procedure with regard to the nomination, other than by or at the direction of the Board of Directors or a committee thereof, of candidates for election as directors (the "Nomination Procedure") and with regard to other matters to be brought by stockholders before an annual meeting of stockholders of the Company (the "Business Procedure"). The Nomination Procedure requires that a stockholder give prior written notice, in proper form, of a planned nomination for the Board of Directors to the Secretary of the Company. The requirements as to the form and timing of that notice are specified in the Company's Bylaws. If the Chairman of the Board of Directors determines that a person was not nominated in accordance with the Nomination Procedure, such person will not be eligible for election as a director. Under the Business Procedure, a stockholder seeking to have any business conducted at an annual meeting must give prior written notice, in proper form, to the Secretary of the Company. The requirements as to the form and timing of that notice are specified in the Company's Bylaws. If the Chairman of the Board of Directors determines that the other business was not properly brought before such meeting in accordance with the Business Procedure, such business will not be conducted at such meeting. Although the Company's Bylaws do not give the Board of Directors any power to approve or disapprove stockholder nominations for the election of directors or of any other business desired by stockholders to be conducted at an annual or any other meeting, the Company's Bylaws (i) may have the effect of precluding a nomination for the election of directors or precluding the conduct of business at a particular meeting if the proper procedures are not followed or (ii) may discourage or deter a third party from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of the Company, even if the conduct of such solicitation or such attempt might be beneficial to the Company and its stockholders. TRANSFER AGENT AND REGISTRAR The Transfer Agent and Registrar for the Common Stock is 55 SHARES ELIGIBLE FOR FUTURE SALE Upon consummation of the Mergers and completion of this Offering, the Company will have outstanding 20,060,774 shares of Common Stock. The 6,100,000 shares sold in this Offering (plus any additional shares sold upon exercise of the Underwriters' over-allotment option) will be freely tradeable without restriction unless acquired by affiliates of the Company. None of the remaining outstanding shares of Common Stock or Restricted Common Stock have been registered under the Securities Act, which means that they may be resold publicly only upon registration under the Securities Act or in compliance with an exemption from the registration requirements of the Securities Act, including the exemption provided by Rule 144 thereunder. In general, under Rule 144, if a period of at least one year has elapsed between the later of the date on which restricted securities were acquired from the Company or the date on which they were acquired from an affiliate, the holder of such restricted securities (including an affiliate) is entitled to sell a number of shares within any three-month period that does not exceed the greater of (i) one percent of the then outstanding shares of the Common Stock (approximately 200,608 shares upon completion of this Offering) or (ii) the average weekly reported volume of trading of the Common Stock during the four calendar weeks preceding such sale. Sales under Rule 144 are also subject to certain requirements pertaining to the manner of such sales, notices of such sales and the availability of current public information concerning the Company. Affiliates may sell shares not constituting restricted securities in accordance with the foregoing volume limitations and other requirements but without regard to the one year holding period. Under Rule 144(k), if a period of at least two years has elapsed between the later of the date on which restricted securities were acquired from the Company and the date on which they were acquired from an affiliate, a holder of such restricted securities who is not an affiliate at the time of the sale and has not been an affiliate for a least three months prior to the sale is entitled to sell the shares immediately without regard to the volume limitations and other conditions described above. The Company and its officers, directors and certain stockholders, who beneficially own 4,239,847 shares in the aggregate, have agreed not to sell or otherwise dispose of any shares of Common Stock or Restricted Common Stock for a period of 180 days after the date of this Prospectus without the prior written consent of Alex. Brown & Sons Incorporated, except that the Company may issue Common Stock in connection with acquisitions, in connection with its 1997 Long-Term Incentive Plan and its 1997 Non-Employee Directors' Stock Plan (the "Plans") or upon conversion of shares of the Restricted Common Stock. See "Underwriting." In addition, all of the stockholders of the Founding Companies and the Company's officers, directors and certain stockholders have agreed with the Company that they will not sell any of their shares for a period of one year after the closing of this Offering. These stockholders, however, have the right, in the event the Company proposes to register under the Securities Act any Common Stock for its own account or for the account of others, subject to certain exceptions, to require the Company to include their shares in the registration, subject to the right of the Company to exclude some or all of the shares in the offering upon the advice of the managing underwriter. In addition, certain of such stockholders have certain limited demand registration rights to require the Company to register shares held by them following the first anniversary of the closing of this Offering. Within 90 days after the closing of this Offering, the Company intends to register 8,000,000 shares of its Common Stock under the Securities Act for use by the Company in connection with future acquisitions. Upon such registration, these shares will generally be freely tradeable after their issuance. In some instances, however, the Company may contractually restrict the sale of shares issued in connection with future acquisitions. The piggyback registration rights described above do not apply to the registration statement relating to these 8,000,000 shares. Prior to this Offering, there has been no public market for the Common Stock, and no prediction can be made as to the effect, if any, that the sale of shares or the availability of shares for sale will have on the market price for the Common Stock prevailing from time to time. Nevertheless, sales, or the availability for sale of, substantial amounts of the Common Stock in the public market could adversely affect prevailing market prices and the future ability of the Company to raise equity capital and complete any additional acquisitions for Common Stock. 56 UNDERWRITING Subject to the terms and conditions of the Underwriting Agreement, the underwriters named below (the "Underwriters"), through their representatives, Alex. Brown & Sons Incorporated, Bear, Stearns & Co. Inc., Donaldson, Lufkin & Jenrette Securities Corporation and Sanders Morris Mundy Inc. (together, the "Representatives"), have severally agreed to purchase from the Company the following respective number of shares of Common Stock at the initial public offering price less the underwriting discounts and commissions set forth on the cover page of this Prospectus: NUMBER OF UNDERWRITERS SHARES - ---------------------------------------- --------- Alex. Brown & Sons Incorporated......... Bear, Stearns & Co. Inc................. Donaldson, Lufkin & Jenrette Securities Corporation........................... Sanders Morris Mundy Inc................ --------- Total.............................. 6,100,000 ========= The Underwriting Agreement provides that the obligations of the Underwriters are subject to certain conditions precedent and that the Underwriters will purchase all of the shares of Common Stock offered hereby if any of such shares are purchased. The Company has been advised by the Representatives that the Underwriters propose to offer the shares of Common Stock to the public at the initial public offering price set forth on the cover page of this Prospectus and to certain dealers at such price less a concession not in excess of $ per share. The Underwriters may allow, and such dealers may re-allow, a concession not in excess of $ per share to certain other dealers. After commencement of the initial public offering, the offering price and other selling terms may be changed by the Representatives. The Company has granted the Underwriters an option, exercisable not later than 30 days after the date of this Prospectus, to purchase up to 915,000 additional shares of Common Stock at the initial public offering price less the underwriting discounts and commissions set forth on the cover page of this Prospectus. To the extent that the Underwriters exercise such option, each of the Underwriters will have a firm commitment to purchase approximately the same percentage thereof that the number of shares of Common Stock to be purchased by it in the above table bears to 6,100,000, and the Company will be obligated, pursuant to the option, to sell such shares to the Underwriters. The Underwriters may exercise such option only to cover over-allotments made in connection with the sale of the Common Stock offered hereby. If purchased, the Underwriters will offer such additional shares on the same terms as those on which the 6,100,000 shares are being offered. The Underwriting Agreement contains covenants of indemnity and contribution between the Underwriters and the Company regarding certain liabilities, including liabilities under the Securities Act. To facilitate the Offering of the Common Stock, the Underwriters may engage in transactions that stabilize, maintain or otherwise affect the market price of the Common Stock. Specifically, the Underwriters 57 may over-allot shares of the Common Stock in connection with this Offering, thereby creating a short position in the Underwriters' syndicate account. Additionally, to cover such over-allotments or to stabilize the market price of the Common Stock, the Underwriters may bid for, and purchase, shares of the Common Stock in the open market. Any of these activities may maintain the market price of the Common Stock at a level above that which might otherwise prevail in the open market. The Underwriters are not required to engage in these activities, and, if commenced, any such activities may be discontinued at any time. The Representatives, on behalf of the Underwriters, also may reclaim selling concessions allowed to an Underwriter or dealer, if the syndicate repurchases shares distributed by that Underwriter or dealer. The Company has agreed that it will not sell or offer any shares of Common Stock or options, rights or warrants to acquire any Common Stock for a period of 180 days after the date of this Prospectus without the prior written consent of Alex. Brown & Sons Incorporated, except for shares issued (i) in connection with acquisitions, (ii) pursuant to the exercise of options granted under the Plans, and (iii) upon conversion of shares of Restricted Common Stock. Further, the Company's directors, officers and certain stockholders, who beneficially own 4,239,847 shares in the aggregate, have agreed not to directly or indirectly sell or offer for sale or otherwise dispose of any Common Stock for a period of 180 days after the date of this Prospectus without the prior written consent of Alex. Brown & Sons Incorporated. The Representatives have advised the Company that the Underwriters do not intend to confirm sales to any account over which they exercise discretionary authority. Certain employees of Donaldson, Lufkin & Jenrette Securities Corporation, one of the Representatives, are investors in Notre, and as a result beneficially own an aggregate of less than 1% of the Common Stock to be outstanding after this Offering. A principal of Sanders Morris Mundy Inc., one of the Representatives, is also an investor in Notre. In February 1997, that principal and an investment fund affiliated with Sanders Morris Mundy Inc. each purchased notes from Notre which are convertible into shares of Common Stock upon consummation of this Offering. The shares of Common Stock beneficially owned by that principal and that investment fund also represent less than 1% of the Common Stock to be outstanding after this Offering. Prior to this Offering, there has been no public market for the Common Stock. Consequently, the initial public offering price for the Common Stock has been determined by negotiations between the Company and the Representatives. Among the factors considered in such negotiations were prevailing market conditions, the results of operations of the Founding Companies in recent periods, the market capitalization and stages of development of other companies which the Company and the Representatives believed to be comparable to the Company, estimates of the business potential of the Company, the present state of the Company's development and other factors deemed relevant by the Company and the Representatives. LEGAL MATTERS The validity of the Common Stock offered hereby will be passed on for the Company by Bracewell & Patterson, L.L.P., Houston, Texas. Certain legal matters related to this Offering will be passed on for the Underwriters by Piper & Marbury, L.L.P., Baltimore, Maryland.

AND FOUNDING COMPANIES UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS BASIS OF PRESENTATION The following unaudited pro forma combined financial statements give effect to the acquisitions by Comfort Systems USA, Inc. ("Comfort Systems") of the outstanding capital stock of Quality, Atlas, Tri-City, Lawrence, Accurate, Eastern, CSI/Bonneville, Seasonair, Western, Freeway and Standard (together, the "Founding Companies"). These acquisitions (the "Mergers") will occur simultaneously with the closing of Comfort Systems' initial public offering (the "Offering") and will be accounted for using the purchase method of accounting. Quality, one of the Founding Companies, has been identified as the accounting acquiror for financial statement presentation purposes. The unaudited pro forma combined balance sheet gives effect to the Mergers and the Offering as if they had occurred on December 31, 1996. The unaudited pro forma combined statements of operations gives effect to these transactions as if they had occurred on January 1, 1996. Comfort Systems has preliminarily analyzed the savings that it expects to be realized from reductions in salaries and certain benefits to the owners. To the extent the owners of the Founding Companies have agreed prospectively to reductions in salary, bonuses and benefits, these reductions have been reflected in the pro forma combined statements of operations. With respect to other potential cost savings, Comfort Systems has not and cannot quantify these savings until completion of the combination of the Founding Companies. It is anticipated that these savings will be offset by costs related to Comfort Systems' new corporate management and by the costs associated with being a public company. However because these costs cannot be accurately quantified at this time, they have not been included in the pro forma financial information of Comfort Systems. The pro forma adjustments are based on estimates, available information and certain assumptions and may be revised as additional information becomes available. The pro forma financial data do not purport to represent what Comfort Systems' financial position or results of operations would actually have been if such transactions in fact had occurred on those dates and are not necessarily representative of the Comfort Systems' financial position or results of operations for any future period. Since the Founding Companies were not under common control or management, historical combined results may not be comparable to, or indicative of, future performance. The unaudited pro forma combined financial statements should be read in conjunction with the other financial statements and notes thereto included elsewhere in this Prospectus. See "Risk Factors" included elsewhere herein. F-2 COMFORT SYSTEMS USA, INC. UNAUDITED PRO FORMA COMBINED BALANCE SHEETS DECEMBER 31, 1996 (AMOUNTS IN THOUSANDS)

The accompanying notes are an integral part of this financial statement. F-9 COMFORT SYSTEMS USA, INC. NOTES TO FINANCIAL STATEMENTS 1. BUSINESS AND ORGANIZATION: Comfort Systems USA, Inc., a Delaware corporation, ("Comfort Systems" or the "Company") was founded in December 1996 to become a national provider of comprehensive HVAC installation services and maintenance, repair and replacement of HVAC systems, focusing primarily on the commercial and industrial markets. Comfort intends to acquire 12 U.S. businesses (the "Mergers"), complete an initial public offering (the "Offering") of its common stock and, subsequent to the Offering, continue to acquire through merger or purchase, similar companies to expand its national operations. Comfort has not conducted any operations, and all activities to date have related to the Offering and the Mergers. Cash of $1,000 was generated from the initial capitalization of the Company (see Note 2). All other expenditures to date have been funded by the primary stockholder, Notre Capital Ventures II, LLC ("Notre"), on behalf of the Company. Accordingly, statements of operations, changes in stockholder's equity and cash flows would not provide meaningful information and have been omitted. Notre has committed to fund the organization expenses and offering costs. As of December 31, 1996, costs of approximately $177,000 have been incurred by Notre in connection with the Offering. Comfort Systems has treated these costs as deferred offering costs. Comfort Systems is dependent upon the Offering to execute the pending Mergers. There is no assurance that the pending Mergers discussed below will be completed or that Comfort Systems will be able to generate future operating revenues. 2. STOCKHOLDER'S EQUITY: COMMON STOCK AND PREFERRED STOCK Comfort Systems effected a 121.1387-for-one stock split on March 19, 1997 for each share of common stock of the Company ("Common Stock") then outstanding. In addition, the Company increased the number of authorized shares of Common Stock to 52,969,912 and authorized 5,000,000 shares of $.01 par value preferred stock. The effects of the Common Stock split and the increase in the shares of authorized Common Stock have been retroactively reflected on the balance sheet and in the accompanying notes. In connection with the organization and initial capitalization of Comfort Systems, the Company issued 121,139 shares of common stock at $.01 per share to Notre. In January 1997, the Company issued 2,848,773 additional shares to Notre for $.01 per share. In January and February 1997, the Company issued a total of 1,269,935 shares of Common Stock to management and consultants to the Company at a price of $.01 per share. As a result, the Company will record a non-recurring, non-cash compensation charge of $6.5 million in the first quarter of 1997, representing the difference between the amount paid for the shares and an estimated fair value of the shares on the date of sale. RESTRICTED COMMON STOCK In March 1997, the primary stockholder exchanged its 2,969,912 shares of Common Stock for an equal number of shares of restricted voting common stock ("Restricted Common Stock"). The holder of Restricted Common Stock is entitled to elect one member of the Company's Board of Directors and to one-half of one vote for each share on all other matters. Each share of Restricted Common Stock will automatically convert to Common Stock on a share for share basis (i) in the event of a disposition of such share of Restricted Common Stock by Notre, (ii) in the event any person acquires beneficial ownership of 15% or more of the total outstanding shares of Common Stock, (iii) in the event any person offers to acquire 15% or more of the total outstanding shares of Common Stock, (iv) at any time after the second anniversary of this Offering, at the election of Notre, (v) on the fifth anniversary of the consummation of the Offering or (vi) in the event a majority of the aggregate number of votes which may be cast by the holders of the total outstanding shares of Common Stock and Restricted Common Stock entitled to vote appprove such conversion. Following exercise or expiration of the Underwriters' over-allotment option granted in connection with the Offering, a number of shares of Restricted Common Stock will be automatically converted into shares of Common Stock so that the aggregate number of votes attributable to (i) the shares of Common Stock issued and outstanding prior to F-10 COMFORT SYSTEMS USA, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) this Offering (excluding shares issued in the Mergers), (ii) the shares of Common Stock issuable on conversion of such shares of Restricted Common Stock, and (iii) unconverted shares of Restricted Common Stock, equals 19.9% of the aggregate number of votes attributable to all shares of Common Stock and Restricted Common Stock outstanding immediately following the exercise or expiration of the Underwriters' over-allotment option. After July 1, 1998, the Board of Directors may elect to convert any remaining shares of Restricted Common Stock into shares of Common Stock in the event 80% or more of the originally outstanding shares of Restricted Common Stock have been previously converted into shares of Common Stock. LONG-TERM INCENTIVE PLAN In March 1997, the Company's stockholders approved the Company's 1997 Long-Term Incentive Plan (the "Plan"), which provides for the granting or awarding of incentive or non-qualified stock options, stock appreciation rights, restricted or deferred stock, dividend equivalents and other incentive awards to directors, officers, key employees and consultants to the Company. The number of shares authorized and reserved for issuance under the Plan is the greater of 2,500,000 shares or 13% of the aggregate number of shares of Common Stock outstanding. The terms of the option awards will be established by the Compensation Committee of the Company's Board of Directors. The Company intends to file a registration statement on Form S-8 under the Securities Act registering the issuance of shares upon exercise of options granted under this Plan. The Company expects to grant non-qualified stock options to purchase a total of 675,000 shares of Common Stock to key employees of the Company at the initial public offering price upon consummation of the Offering. In addition, the Company expects to grant options to purchase a total of 1,271,602 shares of Common Stock to certain employees of the Founding Companies at the initial Offering price per share. These options will vest at the rate of 20% per year, commencing on the first anniversary of the Offering and will expire seven years from the date of grant or three months following termination of employment. NON-EMPLOYEE DIRECTORS STOCK PLAN In March 1997, the Company's stockholders approved the 1997 Non-Employee Directors' Plan (the "Directors' Plan"), which provides for the granting or awarding of stock options and stock appreciation rights to nonemployees. The number of shares authorized and reserved for issuance under the Stock Plan is 250,000 shares. The Directors' Plan provides for the automatic grant of options to purchase 10,000 shares to each non-employee director serving at the commencement of the Offering. Each non-employee director will be granted options to purchase an additional 10,000 shares at the time of the initial election. In addition, each director will be automatically granted options to purchase 5,000 shares at each annual meeting of the stockholders occurring more than two months after the date of the director's initial election. All options will be exercised at the fair market value at the date of grant and are immediately vested upon grant. Options were granted to each of the future and two current members of the board of directors to purchase 10,000 shares of Common Stock at the initial Offering price per share effective upon the consummation of this Offering. These options will expire the earlier of 10 years from the date of grant or one year after termination of service as a director. The Directors' Plan allows non-employee directors to receive shares ("deferred shares") at future settlement dates in lieu of cash. The number of deferred shares will have an aggregate fair market value equal to the fees payable to the directors. 3. STOCK BASED COMPENSATION: Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation," allows entities to choose between a new fair value based method of accounting for employee stock options or similar equity instruments and the current intrinsic, value-based method of accounting prescribed by Accounting Principles Board Opinion No. 25 ("APB No. 25"). Entities electing to remain with the accounting in APB Opinion No. 25 must make pro forma disclosures of net income and F-11 COMFORT SYSTEMS USA, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) earnings per share as if the fair value method of accounting had been applied. The Company will provide pro forma disclosure of net income and earnings per share, as applicable, in the notes to future consolidated financial statements. 4. SUBSEQUENT TO THE DATE OF AUDITORS' REPORT (UNAUDITED): Wholly-owned subsidiaries of Comfort Systems have signed definitive agreements to acquire by merger or share exchange 12 companies ("Founding Companies") to be effective with the Offering. The companies to be acquired are Accurate Air Systems, Inc., Atlas Comfort Services USA, Inc. and Subsidiary, Contract Service, Inc., Eastern Heating and Cooling, Inc., Freeway Heating and Air Conditioning, Inc., Quality Air Heating & Cooling, Inc., Seasonair, Inc., S.M. Lawrence Inc. and Related Company, Standard Heating and Air Conditioning Company, Tech Heating and Air Conditioning, Inc. and Related Company, Tri-City Mechanical, Inc. and Western Building Services, Inc.

On March 26, 1997, Comfort Systems filed a registration statement on Form S-1 for the sale of its common stock. See "Risk Factors" included elsewhere herein. The Company is negotiating with a group of banks to obtain a credit facility which would be available upon the closing of the Offering.

The facility is intended to be used for acquisitions, capital expenditures, refinancing of debt not paid out of the proceeds of this Offering and for general corporate purposes. There can be no assurance that any line of credit will be obtained or that, if obtained, it will be on terms that are favorable to the Company.

The accompanying notes are an integral part of these financial statements. F-17 QUALITY AIR HEATING & COOLING, INC. NOTES TO FINANCIAL STATEMENTS 1. BUSINESS AND ORGANIZATION: Quality Air Heating & Cooling, Inc., a Michigan corporation, (the "Company") focuses on providing "design and build" installation services and maintenance, repair and replacement of HVAC systems primarily for mid-sized to large commercial facilities. Quality primarily operates throughout western Michigan. The Company and its shareholders intend to enter into a definitive agreement with Comfort Systems USA, Inc. ("Comfort Systems"), pursuant to which all outstanding shares of the Company's common stock will be exchanged for cash and shares of Comfort Systems common stock concurrently with the consummation of the initial public offering (the "Offering") of the common stock of Comfort Systems. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. INVENTORIES Inventories consist of parts and supplies held for use in the ordinary course of business and are stated at the lower of cost or market using the first-in, first-out (FIFO) method. PROPERTY AND EQUIPMENT Property and equipment are stated at cost, and depreciation is computed using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the estimated useful life of the asset. Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures for major renewals and betterments, which extend the useful lives of existing equipment, are capitalized and depreciated. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the statement of operations. REVENUE RECOGNITION The Company recognizes revenue when services are performed except when work is being performed under a construction contract. Revenues from construction contracts are recognized on the percentage-of-completion method measured by the percentage of costs incurred to total estimated costs for each contract. Provisions for the total estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, estimated profitability and final contract settlements may result in revisions to costs and income and their effects are recognized in the period in which the revisions are determined. The balances billed but not paid by customers pursuant to retainage provisions in construction contracts will be due upon completion of the contracts and acceptance by the customer. Based on the Company's experience with similar contracts in recent years, the retention balance will be billed and collected in the upcoming fiscal year. WARRANTY COSTS The Company warrants labor for the first year after installation on new air conditioning and heating systems. The Company generally warrants labor for 30 days after servicing of existing air conditioning and heating systems. A reserve for warranty costs is recorded upon completion of installation or service. F-18 QUALITY AIR HEATING & COOLING, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) INCOME TAXES The Company has elected S Corporation status as defined by the Internal Revenue Code, whereby the Company is not subject to taxation for federal purposes. Under S Corporation status, the shareholders report their share of the Company's taxable earnings or losses in their personal tax returns. The Company will terminate its S Corporation status concurrently with the effective date of this Offering. Included in current assets are deposits to prepay certain of the shareholders' federal income taxes. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NEW ACCOUNTING PRONOUNCEMENT Effective January 1, 1996, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that facts and circumstances indicate that property and equipment or other assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset is compared to the asset's carrying amount to determine if a write-down to market value is necessary. Adoption of this standard did not have a material effect on the financial position or results of operations of the Company. 3.

The rent paid under this lease was approximately $20,000 for each of the years ended March 31, 1995 and 1996, and December 31, 1996.

F-21 QUALITY AIR HEATING & COOLING, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) INSURANCE The Company carries a broad range of insurance coverage, including business auto liability, general liability and an umbrella policy. The Company has not incurred significant claims or losses on any of these insurance policies. The Company is self-insured for medical claims up to $30,000 per year per covered individual. Additionally, the Company is part of the state's workers' compensation plan and is responsible for claims up to $275,000 per accident with a maximum aggregate exposure for twenty four months of $648,000. Claims in excess of these amounts are covered by a stop-loss policy. Under the state's policy, the Company has a $300,000 letter of credit which expires December 31, 1997. The Company has recorded reserves for its portion of self-insured claims based on estimated claims incurred through March 31, 1995 and 1996 and December 31, 1996. ROYALTY AGREEMENT The Company is obligated to pay royalties ranging from 1% to 4.5% based on the level of service revenues through December 1, 2001, for management systems support.

EVENT SUBSEQUENT TO DATE OF AUDITORS' REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS (UNAUDITED): In March 1997, the Company and its shareholders entered into a definitive agreement with a wholly-owned subsidiary of Comfort Systems, providing for the merger of the Company with the subsidiary of Comfort Systems. In connection with the merger, the Company will make a cash distribution of approximately $5,914,000 prior to the merger which represents the Company's estimated S Corporation accumulated adjustment account. Had these transactions been recorded at December 31, 1996, the effect on the accompanying balance sheet would be a decrease in assets of $2,351,000, an increase in liabilities of $3,563,000 and a decrease in shareholders' equity of $5,914,000. F-22 REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To Atlas Comfort Services USA, Inc.: We have audited the accompanying consolidated balance sheets of Atlas Comfort Services USA, Inc.

The accompanying notes are an integral part of these consolidated financial statements. F-27 ATLAS COMFORT SERVICES USA, INC. AND SUBSIDIARY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. BUSINESS AND ORGANIZATION: Atlas Comfort Services USA, Inc., a Texas corporation, and its subsidiary (the "Company") is a leading provider of HVAC installation services for apartment complexes, condominiums and hotels in the United States and also provides maintenance, repair and replacement of HVAC systems. Atlas primarily operates in the southwest, northeast, and the mid-Atlantic regions of the United States. The Company and its shareholders intend to enter into a definitive agreement with Comfort Systems USA, Inc. ("Comfort Systems"), pursuant to which all outstanding shares of the Company's common stock will be exchanged for cash and shares of Comfort Systems common stock concurrently with the consummation of the initial public offering (the "Offering") of the common stock of Comfort. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: BASIS OF PRESENTATION The consolidated financial statements include the accounts and results of operations of the Company and its subsidiary which are under common control and management of two individuals. All significant intercompany transactions and balances have been eliminated in combination. CASH AND CASH EQUIVALENTS The Company considers all highly liquid debt investments purchased with an original maturity of three months or less to be cash equivalents. INVENTORIES Inventories consist of duct materials, air conditioning equipment, refrigeration supplies and accessories held for use in the ordinary course of business and are stated at the lower of cost or market using the first-in, first-out (FIFO) method. PROPERTY AND EQUIPMENT Property and equipment are stated at cost, and depreciation is computed using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the estimated useful life of the asset. Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures for major renewals and betterments, which extend the useful lives of existing equipment, are capitalized and depreciated. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the statements of operations. REVENUE RECOGNITION The Company recognizes revenue when services are performed except when work is being performed under a construction contract. Revenues from construction contracts are recognized on the percentage-of-completion method measured by the percentage of costs incurred to total estimated costs for each contract. Provisions for the total estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, estimated profitability and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. The balances billed but not paid by customers pursuant to retainage provisions in construction contracts will be due upon completion of the contracts and acceptance by the customer. Based on the F-28 ATLAS COMFORT SERVICES USA, INC. AND SUBSIDIARY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Company's experience with similar contracts in recent years, the retention balance will be billed and collected in the upcoming fiscal year. WARRANTY COSTS The Company warrants labor for the first year after installation on new air conditioning and heating units. The Company generally warrants labor for 30 days after servicing of existing air conditioning and heating units. A reserve for warranty costs is recorded upon completion of installation or service. INCOME TAXES The Company follows the liability method of accounting for income taxes in accordance with Statement of Financial Accounting Standards (SFAS) No. 109. Under this method, deferred income taxes are recorded based upon the differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the underlying assets or liabilities are recovered or settled. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. GOODWILL Goodwill, in the amount of $33,000, represents the excess of cost over the fair value of net assets acquired and is amortized using the straight-line method over 40 years. The Company assesses the recoverability of its goodwill whenever adverse events occur and believes that no material impairment exists. NEW ACCOUNTING PRONOUNCEMENTS Effective July 1, 1996, the Company adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that facts and circumstances indicate that property and equipment, and intangible or other assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset's carrying amount to determine if a write-down to market value is necessary. Adoption of this standard did not have a material effect on the financial position or results of operations of the Company. F-29 ATLAS COMFORT SERVICES USA, INC.

F-40 TRI-CITY MECHANICAL, INC. NOTES TO FINANCIAL STATEMENTS 1. BUSINESS AND ORGANIZATION: Tri-City Mechanical, Inc., an Arizona corporation, (the "Company") focuses on providing "design and build" installation services and maintenance, repair and replacement of HVAC systems primarily for large commercial and industrial facilities, as well as process piping for industrial facilities. In addition, Tri-City operates a full service sheet metal and ductwork fabrication facility for its installation services. Tri-City primarily operates in Arizona, California, and Nevada. The Company and its shareholders intend to enter into a definitive agreement with Comfort Systems USA, Inc. ("Comfort Systems") pursuant to which all outstanding shares of the Company's common stock will be exchanged for cash and shares of Comfort Systems common stock concurrently with the consummation of the initial public offering (the "Offering") of the common stock of Comfort Systems. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. RESTRICTED CASH The Company also maintains restricted cash which consists of certificates of deposit. These certificates of deposit are held in a joint checking account between the contractors and Tri-City for the retainage balance due from contractors at the completion of the job. INVENTORIES Inventories consist of duct materials, air conditioning equipment, refrigeration supplies and accessories held for use in the ordinary course of business and are stated at the lower of cost or market using the first-in, first-out (FIFO) method. INVESTMENTS The Company has adopted Statement of Financial Accounting Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and Equity Securities," which requires that investments in debt securities and marketable equity securities be designated as trading, held-to-maturity or available-for-sale. At December 31, 1996, investments have been categorized as held-to-maturity, are stated at cost, and are classified in the balance sheet as current assets. Investments at December 31, 1996 consist of U.S. Treasury Bills. PROPERTY AND EQUIPMENT Property and equipment are stated at cost, and depreciation is computed using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the estimated useful life of the asset. Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures for major renewals and betterments, which extend the useful lives of existing equipment, are capitalized and depreciated. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the statement of operations. F-41 TRI-CITY MECHANICAL, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) REVENUE RECOGNITION The Company recognizes revenue when services are performed except when work is being performed under a construction contract. Revenues from construction contracts are recognized on the percentage-of-completion method measured by the percentage of costs incurred to total estimated costs for each contract. Provisions for the total estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, estimated profitability and final contract settlements may result in revisions to costs and income and their effects are recognized in the period in which the revisions are determined. The balances billed but not paid by customers pursuant to retainage provisions in construction contracts will be due upon completion of the contracts and acceptance by the customer. Based on the Company's experience with similar contracts in recent years, the retention balance will be billed and collected in the upcoming fiscal year. WARRANTY COSTS The Company warrants labor for the first year after installation on new air conditioning and heating systems. The Company generally warrants labor for 30 days after servicing of existing air conditioning and heating systems. A reserve for warranty costs is recorded upon completion of installation or service. INCOME TAXES The Company has elected S Corporation status as defined by the Internal Revenue Code, whereby the Company is not subject to taxation for federal purposes. Under S Corporation status, the shareholders report their share of the Company's taxable earnings or losses in their personal tax returns. The Company will terminate its S Corporation status concurrently with the effective date of the Offering. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NEW ACCOUNTING PRONOUNCEMENT Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that facts and circumstances indicate that property and equipment may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset is compared to the asset's carrying amount to determine if a write-down to market value is necessary. Adoption of this standard did not have a material effect on the financial position or results of operations of the Company. F-42 TRI-CITY MECHANICAL, INC.

The Company has not incurred significant claims or losses on any of its insurance policies. 10.

EVENT SUBSEQUENT TO DATE OF AUDITORS' REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS (UNAUDITED): In March 1997, the Company and its shareholders entered into a definitive agreement with a wholly-owned subsidiary of Comfort Systems, providing for the merger of the Company with the subsidiary of Comfort Systems. In connection with the merger the Company will make a cash distribution of approximately $6,019,000 prior to the merger which represents the Company's estimated S Corporation accumulated adjustment account. Had these transactions been recorded at December 31, 1996, the effect on the accompanying balance sheet would be a decrease in assets of $2,477,000, an increase in liabilities of $3,542,000 and a decrease in shareholders' equity of $6,019,000. Concurrently with the merger, the Company will enter into agreements with the shareholders to lease land and buildings used in the Company's operations for a negotiated amount and term. Tri-City has a verbal commitment with a limited liability corporation owned by Mr. Nothum, Jr. and his father to construct new office, operations and warehouse facilities.

F-50 S.M. LAWRENCE INC. AND RELATED COMPANY NOTES TO COMBINED FINANCIAL STATEMENTS 1. BUSINESS AND ORGANIZATION: S.M. Lawrence Inc., a Tennessee corporation (the "Company") focuses on providing "design and build" installation services and process piping primarily for industrial facilities and maintenance, repair and replacement of commercial and industrial HVAC systems. S.M. Lawrence primarily operates in Tennessee and the immediately surrounding states. The Company and its shareholders intend to enter into a definitive agreement with Comfort Systems USA, Inc. ("Comfort Systems") pursuant to which all outstanding shares of the Company's common stock will be exchanged for cash and shares of Comfort Systems common stock concurrently with the consummation of the initial public offering (the "Offering") of the common stock of Comfort Systems. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: BASIS OF PRESENTATION The financial statements include the accounts and results of operations of S.M. Lawrence Inc. and Lawrence Services, Inc. which are under common control and management of two individuals. All significant intercompany transactions and balances have been eliminated in combination. CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. INVENTORIES Inventories consist of duct materials, air conditioning equipment, refrigeration supplies and accessories held for use in the ordinary course of business and are stated at the lower of cost or market using the first-in, first-out (FIFO) method. PROPERTY AND EQUIPMENT Property and equipment are stated at cost, and depreciation is computed using an accelerated method of depreciation. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the estimated useful life of the asset. Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures for major renewals and betterments, which extend the useful lives of existing equipment, are capitalized and depreciated. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the statements of operations. REVENUE RECOGNITION The Company recognizes revenue when services are performed except when work is being performed under a construction contract. Revenues from construction contracts are recognized on the percentage-of-completion method measured by the percentage of costs incurred to total estimated costs for each contract. Provisions for the total estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, estimated profitability and final contract settlements may result in revisions to costs and income and their effects are recognized in the period in which the revisions are determined. The balances billed but not paid by customers pursuant to retainage provisions in construction contracts will be due upon completion of the contracts and acceptance by the customer. Based on the Company's experience with similar contracts in recent years, the retention balance will be billed and collected in the upcoming fiscal year. F-51 S.M. LAWRENCE INC. AND RELATED COMPANY NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED) WARRANTY COSTS The Company warrants labor and parts for one year after installation of new air conditioning and heating systems. A reserve for warranty costs is recorded upon completion of installation or service. INCOME TAXES The Company follows the liability method of accounting for income taxes in accordance with Statement of Financial Accounting Standards (SFAS) No. 109. Under this method, deferred income taxes are recorded based upon the differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the underlying assets or liabilities are recovered or settled. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NEW ACCOUNTING PRONOUNCEMENT Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that facts and circumstances indicate that property and equipment, and intangible or other assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset's carrying amount to determine if a write-down to market value is necessary. Adoption of this standard did not have a material effect on the financial position or results of operations of the Company. 3.

The accompanying notes are an integral part of these financial statements. F-61 ACCURATE AIR SYSTEMS, INC. NOTES TO FINANCIAL STATEMENTS 1. BUSINESS AND ORGANIZATION: Accurate Air Systems, Inc., a Texas corporation, (the "Company") focuses on providing "design and build" installation services and maintenance, repair and replacement of HVAC systems for commercial facilities. Accurate primarily operates in Texas, Oklahoma and New Mexico. The Company and its shareholder intend to enter into a definitive agreement with Comfort Systems USA, Inc. ("Comfort Systems") pursuant to which all outstanding shares of the Company's common stock will be exchanged for cash and shares of Comfort Systems common stock concurrently with the consummation of the initial public offering (the "Offering") of the common stock of Comfort Systems. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: CHANGE IN FISCAL YEAR END Effective July 1, 1995, the Company changed its fiscal year end from June 30 to December 31. The statements of operations, shareholder's equity and cash flows for the six months ended December 31, 1995 are presented in the accompanying financial statements. The results of operations for the six month period are not necessarily indicative of the results for a full year period. CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. INVENTORIES Inventories consist of duct materials, air conditioning equipment, refrigeration supplies and accessories held for use in the ordinary course of business and are stated at the lower of cost or market using the weighted-average method. PROPERTY AND EQUIPMENT Property and equipment are stated at cost, and depreciation is computed using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the estimated useful life of the asset. Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures for major renewals and betterments, which extend the useful lives of existing equipment, are capitalized and depreciated. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the statement of operations. REVENUE RECOGNITION The Company recognizes revenue when services are performed except when work is being performed under a construction contract. Revenues from construction contracts are recognized on the percentage-of-completion method measured by the percentage of costs incurred to total estimated costs for each contract. Provisions for the total estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, estimated profitability and final contract settlements may result in revisions to costs and income and their effects are recognized in the period in which the revisions are determined. The balances billed but not paid by customers pursuant to retainage provisions in construction contracts will be due upon completion of the contracts and acceptance by the customer. Based on the Company's experience with similar contracts in recent years, the retention balance will be billed and collected in the upcoming fiscal year. F-62 ACCURATE AIR SYSTEMS, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) WARRANTY COSTS The Company warrants labor for the first year after installation on new air conditioning and heating systems. The Company generally warrants labor for 90 days after the servicing of existing air conditioning and heating systems. A reserve for warranty costs is recorded upon completion of installation or service. INCOME TAXES Effective July 1, 1995, the Company elected S Corporation status as defined by the Internal Revenue Code whereby the Company is not subject to taxation for federal purposes. Under S Corporation status, each shareholder reports his share of the Company's taxable earnings or losses in his personal federal and state tax returns. The balance in the deferred tax liability account at July 1, 1995 was credited to income during the six month period ended December 31, 1995. Prior to July 1, 1995, the Company followed the liability method of accounting for income taxes in accordance with Statement of Financial Accounting Standards (SFAS) No. 109. Under this method, deferred income taxes were recorded based upon differences between the financial reporting and tax bases of assets and liabilities and were measured using the enacted tax rates and laws that would have been in effect when the underlying assets or liabilities were recovered or settled. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NEW ACCOUNTING PRONOUNCEMENT Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that facts and circumstances indicate that property and equipment, and intangible or other assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset's carrying amount to determine if a write-down to market value is necessary. Adoption of this standard did not have a material effect on the financial position or results of operations of the Company. 3.

The agreement provides that the Company may borrow up to 70 percent of its accounts receivable that are less than sixty days past due. The revolving line of credit is secured by accounts receivable and the personal guaranty of the sole shareholder, and requires the Company to maintain certain minimum tangible net worth and cash flow ratios.

NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) 10. SALES TO SIGNIFICANT CUSTOMER: During 1996, one customer accounted for approximately 12 percent of the Company's sales. 11. SUBSEQUENT EVENT: Effective January 2, 1997, an affiliate of the Company acquired the business and certain operating assets of RECC, Inc., a New York corporation. This affiliate agreed to pay $10,000 over a period of one year. 12. EVENT SUBSEQUENT TO DATE OF AUDITORS' REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS (UNAUDITED): In March 1997, the Company and its shareholder entered into a definitive agreement with a wholly-owned subsidiary of Comfort Systems, providing for the merger of the Company with the subsidiary of Comfort Systems. In connection with the merger, the Company will make a cash distribution of approximately $416,000 prior to the merger which represents the Company's estimated S Corporation accumulated adjustment account. Had these transactions been recorded at December 31, 1996, the effect on the accompanying balance sheet would be an increase in liabilities of $416,000 and a decrease in shareholder's equity of $416,000. Concurrently with the merger, the Company will enter into agreements with the shareholders to lease land and buildings used in the Company's operations for the negotiated amount and term. Eastern intends to enter into a 10-year lease with 60 Loudonville Road Associates for a new building and terminate the existing lease. Eastern has agreed to install the HVAC systems in the new building at a price which the Company believes to be at a fair market value. The Company's annual rental in the new building will be at fair market value, as determined by appraisal.

F-83 CONTRACT SERVICE, INC. NOTES TO FINANCIAL STATEMENTS 1. BUSINESS AND ORGANIZATION: Contract Service, Inc., a Utah corporation, (the "Company") focuses on providing comprehensive maintenance, repair and replacement of HVAC systems for commercial and residential facilities primarily in Utah. The Company and its shareholders intend to enter into a definitive agreement with Comfort Systems USA, Inc. ("Comfort Systems"), pursuant to which all outstanding shares of the Company's common stock will be exchanged for cash and shares of Comfort Systems common stock concurrently with the consummation of the initial public offering (the "Offering") of the common stock of Comfort Systems. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. INVENTORIES Inventories consist of duct materials, air conditioning equipment, refrigeration supplies and accessories held for use in the ordinary course of business and are stated at the lower of cost or market using the first-in, first-out (FIFO) method. PROPERTY AND EQUIPMENT Property and equipment are stated at cost, and depreciation is computed using the straight-line method over the estimated useful lives of the assets. Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures for major renewals and betterments, which extend the useful lives of existing equipment, are capitalized and depreciated. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the statement of operations. REVENUE RECOGNITION The Company recognizes revenue when services are performed except when work is being performed under a construction contract. Revenues from construction contracts are recognized on the percentage-of-completion method measured by the percentage of costs incurred to total estimated costs for each contract. Provisions for the total estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, estimated profitability and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. The balances billed but not paid by customers pursuant to retainage provisions in construction contracts will be due upon completion of the contracts and acceptance by the customer. Based on the Company's experience with similar contracts in recent years, the retention balance will be billed and collected in the upcoming fiscal year. WARRANTY COSTS The Company warrants labor for the first year after installation of new air conditioning and heating units. The Company generally warrants labor for 30 days after the servicing of existing air conditioning and heating units. A reserve for warranty costs is recorded upon completion of installation or service. F-84 CONTRACT SERVICE, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) INCOME TAXES The Company has elected S Corporation status as defined by the Internal Revenue Code, whereby the Company is not subject to taxation for federal purposes. Under S Corporation status, the shareholders report their share of the Company's taxable earnings or losses in their personal tax returns. The Company will terminate its S Corporation status concurrently with the effective date of the Offering. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NEW ACCOUNTING PRONOUNCEMENT Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that facts and circumstances indicate that property and equipment, and intangible or other assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset is compared to the asset's carrying amount to determine if a write-down to market value is necessary. Adoption of this standard did not have a material effect on the financial position or results of operations of the Company. 3.

The Company has not incurred significant claims or losses on any of its insurance policies. 9. EMPLOYEE BENEFIT PLAN: Beginning January 1, 1994, the Company adopted a 401(k) plan. The plan allows employees to contribute a portion of their gross wages into the plan as a salary deferral and requires the Company to match 25% of the employee contribution up to 5% of employee's gross wages. The Company's matching contributions for the years ended December 31, 1995 and 1996 were $17,000 and $19,000. The Company has also adopted a cafeteria plan pursuant to Section 125 of the Internal Revenue Code that covers all employees from 90 days after the commencement of employment. Under this plan, the employees may reduce their compensation to fund medical insurance, dental and dependent care/day care benefits. The funds withheld are used to pay actual claims or medical insurance, based on the employees' elections. 10. FINANCIAL INSTRUMENTS: The Company's financial instruments consist of cash and cash equivalents, and debt.

EVENT SUBSEQUENT TO DATE OF AUDITORS' REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS (UNAUDITED): In March 1997, the Company and its shareholders entered into a definitive agreement with a wholly-owned subsidiary of Comfort Systems, providing for the merger of the Company with the subsidiary of Comfort Systems.

The Company will terminate its S Corporation status concurrently with the effective date of the Offering. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NEW ACCOUNTING PRONOUNCEMENT Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that facts and circumstances indicate that property and equipment may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset's carrying amount to determine if a write-down to market value is necessary. Adoption of this standard did not have a material effect on the financial position or combined results of operations of the Company. 3.

F-102 SEASONAIR, INC. NOTES TO FINANCIAL STATEMENTS 1. BUSINESS AND ORGANIZATION: Seasonair, Inc., a Maryland corporation, (the "Company") focuses on providing installation services and maintenance, repair and replacement of HVAC systems for light commercial facilities. Seasonair primarily operates in Maryland, the District of Columbia and Virginia. The Company and its shareholders intend to enter into a definitive agreement with Comfort Systems, USA, Inc. ("Comfort Systems") pursuant to which all outstanding shares of the Company's common stock will be exchanged for cash and shares of Comfort Systems common stock concurrently with the consummation of the initial public offering (the "Offering") of the common stock of Comfort Systems. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. INVENTORIES Inventories consist of duct materials, air conditioning equipment, refrigeration supplies and accessories held for use in the ordinary course of business and are stated at the lower of cost or market using the weighted-average method. PROPERTY AND EQUIPMENT Property and equipment are stated at cost, and depreciation is computed using an accelerated method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the estimated useful life of the asset. Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures for major renewals and betterments, which extend the useful lives of existing equipment, are capitalized and depreciated. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the statement of operations. REVENUE RECOGNITION The Company recognizes revenue when services are performed except when work is being performed under a construction contract. Revenue from construction contracts is recognized on the completed-contract method. This method is used because the typical contract is completed within a twelve-month period, and the Company's current financial position and results of operations do not vary significantly from those which would result from use of the percentage-of-completion method. A contract is considered complete when all costs except insignificant items have been incurred, and the installation is operating according to specifications or has been accepted by the customer. The balances billed but not paid by customers pursuant to retainage provision in construction contracts will be due upon completion of the contracts and acceptance by the customer. Based on the Company's experience with similar contracts in recent years, the retention balance will be billed and collected in the upcoming fiscal year. Contract costs include all direct equipment, material, labor, and subcontract costs. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. F-103 SEASONAIR, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) WARRANTY COSTS The Company warrants labor for the first year after installation on new air conditioning and heating systems. The Company generally warrants labor for 30 days after servicing of existing air conditioning and heating systems. A reserve for warranty costs is recorded upon completion of installation or service. INCOME TAXES The Company follows the liability method of accounting for income taxes in accordance with Statement of Financial Accounting Standards (SFAS) No. 109 "Accounting for Income Taxes". Under this method, deferred income taxes are recorded based upon differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the underlying assets or liabilities are recovered or settled. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NEW ACCOUNTING PRONOUNCEMENT Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that facts and circumstances indicate that property and equipment and intangible or other assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset's carrying amount to determine if a write-down to market value is necessary. Adoption of this standard did not have a material effect on the financial position or results of operations of the Company. 3.

The terms of the notes range from 51 months to 80 months with monthly payments of principal and interest of approximately $3,598. The notes bear interest at rates ranging from 10 percent to 12.7 percent. The aggregate maturities of long-term debt as of December 31, 1996, are as follows (in thousands): Year ending December 31 -- 1997............................... $ 34 1998............................... 37 1999............................... 38 2000............................... 1 --------- $ 110 ========= The Company has a $150,000 line of credit with a financial services company.

WARRANTY COSTS The Company warrants labor for the first year after installation on new air conditioning and heating units. The Company generally warrants labor for 30 days after servicing of existing air conditioning and heating units. A reserve for warranty costs is recorded upon completion of installation or service. INCOME TAXES The Company has elected S Corporation status as defined by the Internal Revenue Code, whereby the Company is not subject to taxation for federal purposes. Under S Corporation status, the shareholders report their share of the Company's taxable earnings or losses in their personal tax returns. The Company will terminate its S Corporation status concurrently with the effective date of this Offering. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NEW ACCOUNTING PRONOUNCEMENT Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that facts and circumstances indicate that property and equipment, and intangible or other assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset's carrying amount to determine if a write-down to market value is necessary. Adoption of this standard did not have a material effect on the financial position or results of operations of the Company. 3.

EMPLOYEE BENEFIT PLANS: The Company has adopted a 401(k) plan which allows the Company to make discretionary contributions and discretionary profit sharing contributions. No contributions were made by the Company under this plan in 1995 and 1996. However, expenses of $2,733 and $3,903 were paid by the Company during 1995 and 1996, respectively. 8.

COMMITMENTS AND CONTINGENCIES: LITIGATION The Company is involved in legal actions arising in the ordinary course of business. Management does not believe the outcome of such legal actions will have a material adverse effect on the Company's financial position or results of operations.

EVENT SUBSEQUENT TO DATE OF AUDITORS' REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS (UNAUDITED): In March 1997, the Company and its shareholders entered into a definitive agreement with a wholly-owned subsidiary of Comfort Systems, providing for the merger of the Company with the subsidiary of Comfort Systems. In connection with the merger, the Company will make a cash distribution of approximately $355,000 prior to the merger which represents the Company's estimated S Corporation accumulated adjustment account. Had these transactions been recorded at December 31, 1996, the effect on the accompanying balance sheet would be a decrease in assets of $77,000, an increase in liabilities of $278,000 and a decrease in shareholders' equity of $355,000.

INDEMNIFICATION OF OFFICERS AND DIRECTORS. The Company's Certificate of Incorporation, as amended, and Bylaws incorporate substantially the provisions of the Delaware General Corporation Law ("DGCL") providing for indemnification of directors and officers of the Company against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding arising by reason of the fact that such person is or was an officer or director of the Company or is or was serving at the request of the Company as a director, officer or employee of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. As permitted by Section 102 of the DGCL, the Company's Certificate of Incorporation, as amended, contains provisions eliminating a director's personal liability for monetary damages to the Company and its stockholders arising from a breach of a director's fiduciary duty except for liability (a) for any breach of the director's duty of loyalty to the Company or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the DGCL, or (d) for any transaction from which the director derived an improper personal benefit. Section 145 of the DGCL provides generally that a person sued as a director, officer, employee or agent of a corporation may be indemnified by the corporation for reasonable expenses, including attorneys' fees, if in the case of other than derivative suits such person has acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation (and, in the case of a criminal proceeding, had no reasonable cause to believe that such person's conduct was unlawful). In the case of a derivative suit, an officer, employee or agent of the corporation which is not protected by the Certificate of Incorporation may be indemnified by the corporation for reasonable expenses, including attorneys' fees, if such person has acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in the case of a derivative suit in respect of any claim as to which an officer, employee or agent has been adjudged to be liable to the corporation unless that person is fairly and reasonably entitled to indemnity for proper expenses. Indemnification is mandatory in the case of a director, officer, employee, or agent who is successful on the merits in defense of a suit against such person. The Company intends to enter into Indemnity Agreements with its directors and certain key officers pursuant to which the Company generally is obligated to indemnify its directors and such officers to the full extent permitted by the DGCL as described above. II-1 The Company intends to purchase liability insurance policies covering directors and officers in certain circumstances. ITEM 15. RECENT SALES OF UNRESTRICTED SECURITIES.

II-4 ITEM 17. UNDERTAKINGS. (a) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the provisions described in Item 14, or otherwise, the Company has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. (b) The undersigned registrant hereby undertakes to provide to the underwriter at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each purchaser. (c) The undersigned registrant hereby undertakes that: (i) for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective; (ii) for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

owned or leased by the COMPANY at the date hereof and all other real property,
if any, used by the COMPANY in the

                                      -18-

conduct of its business. Any such real property owned by the COMPANY will be
sold by the COMPANY and leased back by the COMPANY on terms no less favorable to
the COMPANY than those available from an unaffiliated party and otherwise
reasonably acceptable to CSI at or prior to the Closing Date. True, complete and
correct copies of all leases and agreements in respect of such real property
leased by the COMPANY are attached to Schedule 5.16, and an indication as to
which such properties, if any, are currently owned, or were formerly owned, by
STOCKHOLDER or affiliates of the COMPANY or STOCKHOLDER is included in Schedule
5.16. Except as set forth on Schedule 5.16, all of such leases included on
Schedule 5.16 are in full force and effect and constitute valid and binding
agreements of the parties (and their successors) thereto in accordance with
their respective terms.

        5.17 INSURANCE. The COMPANY has delivered to CSI (i) an accurate list as
of the Balance Sheet Date of all insurance policies carried by the COMPANY, (ii)
an accurate list of all insurance loss runs or workers compensation claims
received for the past three (3) policy years and (iii) true, complete and
correct copies of all insurance policies currently in effect. Such insurance
policies evidence all of the insurance that the COMPANY is required to carry
pursuant to all of its contracts and other agreements and pursuant to all
applicable laws. All of such insurance policies are currently in full force and
effect and shall remain in full force and effect through the Funding and
Consummation Date. Since January 1, 1994, no insurance carried by the COMPANY
has been canceled by the insurer and the COMPANY has not been denied coverage.

        5.18 COMPENSATION; EMPLOYMENT AGREEMENTS; ORGANIZED LABOR MATTERS. The
COMPANY has delivered to CSI an accurate list (which is set forth on Schedule
5.18) showing all officers, directors and key employees of the COMPANY, listing
all employment agreements with such officers, directors and key employees and
the rate of compensation (and the portions thereof attributable to salary, bonus
and other compensation, respectively) of each of such persons as of (i) the
Balance Sheet Date and (ii) the date hereof. The COMPANY has provided to CSI
true, complete and correct copies of any employment agreements for persons
listed on Schedule 5.18. Since the Balance Sheet Date, there have been no
increases in the compensation payable or any special

                                      -19-

bonuses to any officer, director, key employee or other employee, except
ordinary salary increases implemented on a basis consistent with past practices.

               Except as set forth on Schedule 5.18, (i) the COMPANY is not
bound by or subject to (and none of its respective assets or properties is bound
by or subject to) any arrangement with any labor union, (ii) no employees of the
COMPANY are represented by any labor union or covered by any collective
bargaining agreement, (iii) to the knowledge of the COMPANY, no campaign to
establish such representation is in progress and (iv) there is no pending or, to
the best of the COMPANY's knowledge, threatened labor dispute involving the
COMPANY and any group of its employees nor has the COMPANY experienced any labor
interruptions over the past three years. The COMPANY believes its relationship
with employees to be good.

        5.19 EMPLOYEE PLANS. The STOCKHOLDER have delivered to CSI an accurate
schedule (Schedule 5.19) showing all employee benefit plans of COMPANY
(including COMPANY's Subsidiaries), including all employment agreements and
other agreements or arrangements containing "golden parachute" or other similar
provisions, and deferred compensation agreements, together with true, complete
and correct copies of such plans, agreements and any trusts related thereto, and
classifications of employees covered thereby as of the Balance Sheet Date.
Except for the employee benefit plans, if any, described on Schedule 5.19,
COMPANY (including the COMPANY's Subsidiaries) does not sponsor, maintain or
contribute to any plan program, fund or arrangement that constitutes an
"employee pension benefit plan," nor has COMPANY or any Subsidiary any
obligation to contribute to or accrue or pay any benefits under any deferred
compensation or retirement funding arrangement on behalf of any employee or
employees (such as, for example, and without limitation, any individual
retirement account or annuity, any "excess benefit plan" (within the meaning of
Section 3(36) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) or any non-qualified deferred compensation arrangement). For the
purposes of this Agreement, the term "employee pension benefit plan" shall have
the same meaning as is given that term in Section 3(2) of ERISA. Neither COMPANY
nor any Subsidiary has sponsored, maintained or contributed to any employee
pension benefit plan other than the plans set

                                      -20-

forth on Schedule 5.19, nor is COMPANY or any Subsidiary required to contribute
to any retirement plan pursuant to the provisions of any collective bargaining
agreement establishing the terms and conditions or employment of any of
COMPANY's or any Subsidiary's employees.

        Neither the COMPANY nor any Subsidiary is now, or can as a result of its
past activities become, liable to the Pension Benefit Guaranty Corporation or to
any multiemployer employee pension benefit plan under the provisions of Title IV
of ERISA.

        All employee benefit plans listed on Schedule 5.19 and the
administration thereof are in substantial compliance with their terms and all
applicable provisions of ERISA and the regulations issued thereunder, as well as
with all other applicable federal, state and local statutes, ordinances and
regulations.

        All accrued contribution obligations of COMPANY or any Subsidiary with
respect to any plan listed on Schedule 5.19 have either been fulfilled in their
entirety or are fully reflected on the balance sheet of the COMPANY as of the
Balance Sheet Date.

        5.20 COMPLIANCE WITH ERISA. All such plans listed on Schedule 5.19 that
are intended to qualify (the "Qualified Plans") under Section 401(a) of the Code
are, and have been so qualified and have been determined by the Internal Revenue
Service to be so qualified, and copies of such determination letters are
included as part of Schedule 5.19 hereof. Except as disclosed on Schedule 5.20,
all reports and other documents required to be filed with any governmental
agency or distributed to plan participants or beneficiaries (including, but not
limited to, actuarial reports, audits or tax returns) have been timely filed or
distributed, and copies thereof are included as part of Schedule 5.19 hereof.
Neither STOCKHOLDER, any such plan listed in Schedule 5.19, nor COMPANY
(including the COMPANY's Subsidiaries) has engaged in any transaction prohibited
under the provisions of Section 4975 of the Code or Section 406 of ERISA. No
such Plan listed in Schedule 5.19 has incurred an accumulated funding
deficiency, as defined in Section 412(a) of the Code and Section 302(1) of
ERISA; and COMPANY (including the COMPANY's Subsidiaries) has not incurred any
liability for excise tax or penalty due to the Internal Revenue Service nor any
liability to the Pension Benefit Guaranty Corporation. The STOCKHOLDER further
represent that:

                                      -21-

                (i) there have been no terminations, partial terminations or
        discontinuance of contributions to any such Qualified Plan intended to
        qualify under Section 401(a) of the Code without notice to and approval
        by the Internal Revenue Service;

                (ii) no such plan listed in Schedule 5.19 subject to the
        provisions of Title IV of ERISA has been terminated;

                (iii) there have been no "reportable events" (as that phrase is
        defined in Section 4043 of ERISA) with respect to any such plan listed
        in Schedule 5.19;

                (iv) COMPANY (including the COMPANY's Subsidiaries) has not
        incurred liability under Section 4062 of ERISA; and

                (v) No circumstances exist pursuant to which the COMPANY could
        have any direct or indirect liability whatsoever (including, but not
        limited to, any liability to any multiemployer plan or the PBGC under
        Title IV of ERISA or to the Internal Revenue Service for any excise tax
        or penalty, or being subject to any statutory lien to secure payment of
        any such liability) with respect to any plan now or heretofore
        maintained or contributed to by any entity other than the COMPANY that
        is, or at any time was, a member of a "controlled group" (as defined in
        Section 412(n)(6)(B) of the Code) that includes the COMPANY. 

        5.21 CONFORMITY WITH LAW; LITIGATION. Except to the extent set forth on
Schedule 5.21 or 5.13, the COMPANY is not in violation of any law or regulation
or any order of any court or Federal, state, municipal or other governmental
department, commission, board, bureau, agency or instrumentality having
jurisdiction over any of them which would have a Material Adverse Effect; and
except to the extent set forth on Schedule 5.10 or 5.13, there are no material
claims, actions, suits or proceedings, pending or, to the knowledge of the
COMPANY, threatened against or affecting, the COMPANY, at law or in equity, or
before or by any Federal, state, municipal or other governmental department,
commission, board, bureau, agency or instrumentality having jurisdiction over
any of them and no notice of any claim, action, suit or proceeding, whether
pending or threatened, has been received. The COMPANY has conducted and is
conducting its business in substantial compliance with the requirements,
standards, criteria and conditions set forth in

permits, licenses, orders and other governmental approvals set forth on
Schedules 5.12 and 5.13, and is not in violation of any of the foregoing which

        5.22 TAXES. COMPANY (including the COMPANY's Subsidiaries) has timely
filed all requisite federal, state and other tax returns or extension requests
for all fiscal periods ended on or before the Balance Sheet Date; and except as
set forth on Schedule 5.22, there are no examinations in progress or claims
against any of them for federal, state and other taxes (including penalties and
interest) for any period or periods prior to and including the Balance Sheet
Date and no notice of any claim for taxes, whether pending or threatened, has
been received. All tax, including interest and penalties (whether or not shown
on any tax return) owed by the COMPANY, any of the COMPANY's Subsidiaries, any
member of an affiliated or consolidated group which includes or included the
COMPANY or any of the COMPANY's Subsidiaries, or with respect to any payment
made or deemed made by the COMPANY or any of the COMPANY's Subsidiaries herein
been paid. The amounts shown as accruals for taxes on the COMPANY Financial

that date. Copies of (i) any tax examinations, (ii) extensions of statutory
limitations and (iii) the federal and local income tax returns and franchise tax
returns of COMPANY (including the COMPANY Subsidiaries) for their last three (3)
fiscal years, or such shorter period of time as any of them shall have existed,
are attached hereto as Schedule 5.22. The STOCKHOLDER made a valid election
under the provisions of Subchapter S of the Code and the COMPANY has not, within
the past five years, been taxed under the provisions of Subchapter C of the
Code. The COMPANY has a taxable year ended December 31 and has not made an

Code. The COMPANY's methods of accounting have not changed in the past five
years. The COMPANY is not an investment company as defined in Section 351(e)(1)

                                      -23-

        5.23 NO VIOLATIONS. The COMPANY is not in violation of any Charter

the consent or approval of, any governmental agency or other third party with
respect to any of the transactions contemplated hereby in order to remain in
full force and effect and consummation of the transactions contemplated hereby
will not give rise to any right to termination, cancellation or acceleration or
loss of any right or benefit. Except as set forth on Schedule 5.23, none of the
Material Documents prohibits the use or publication by the COMPANY, CSI or NEWCO
of the name of any other party to such Material Document, and none of the

or any Other Founding Company.

affect the accuracy of a representation or warranty of COMPANY or STOCKHOLDER in
this Agreement, in any material respect, the COMPANY and the STOCKHOLDER shall
immediately give notice of such fact or circumstance to CSI. However, subject to
the provisions of Section 7.8, such notification shall not relieve either the
COMPANY or the STOCKHOLDER of their respective obligations under this Agreement,
and, subject to the provisions of Section 7.8, at the sole option of CSI, the
truth and accuracy of any and all warranties and representations of the COMPANY,
or on behalf of the COMPANY and of STOCKHOLDER at the date of this Agreement and
on the Closing Date and on the Funding and Consummation Date, shall be a
precondition to the consummation of this transaction.

                      (b) The COMPANY and the STOCKHOLDER acknowledge and agree
(i) that there exists no firm commitment, binding agreement, or promise or other
assurance of any kind, whether express or implied, oral or written, that a
Registration Statement will become effective or that the IPO pursuant thereto
will occur at a particular price or within a particular range of prices or occur
at all; (ii) that neither CSI or any of its officers, directors, agents or
representatives nor any

                                      -27-

Underwriter shall have any liability to the COMPANY, the STOCKHOLDER or any
other person affiliated or associated with the COMPANY for any failure of the
Registration Statement to become effective, the IPO to occur at a particular
price or within a particular range of prices or to occur at all; and (iii) that
the decision of STOCKHOLDER to enter into this Agreement, or to vote in favor of
or consent to the proposed Merger, has been or will be made independent of, and
without reliance upon, any statements, opinions or other communications, or due
diligence investigations which have been or will be made or performed by any
prospective Underwriter, relative to CSI or the prospective IPO.

thereto.

        7.7 NOTIFICATION OF CERTAIN MATTERS. The STOCKHOLDER and the COMPANY
shall give prompt notice to CSI of (i) the occurrence or non-occurrence of any
event the occurrence or non-occurrence of which would be likely to cause any
representation or warranty of the COMPANY or the STOCKHOLDER contained herein to
be untrue or inaccurate in any material respect at or prior to the Closing and
(ii) any material failure of the STOCKHOLDER or the COMPANY to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
such person hereunder. CSI and NEWCO shall give prompt notice to the COMPANY of
(i) the occurrence or non-occurrence of any event the occurrence or
non-occurrence of which would be likely to cause any representation or warranty
of CSI or NEWCO contained herein to be untrue or inaccurate in any material
respect at or prior to the Closing and (ii) any material failure of CSI or NEWCO
to comply with or satisfy any covenant, condition or agreement to be complied
with or satisfied by it hereunder. The delivery of any notice pursuant to this

to (i) modify the representations or warranties hereunder of the party
delivering such notice, which modification may only be made pursuant to Section

        7.8 AMENDMENT OF SCHEDULES. Each party hereto agrees that, with respect
to the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the COMPANY that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless CSI and
a majority of the Founding Companies other than the COMPANY consent to such
amendment or supplement; and provided further, that no amendment or supplement
to a Schedule prepared by CSI or NEWCO that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless a
majority of the Founding Companies consent to such amendment or supplement. For
all purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other
Founding Companies seeks to amend or supplement a Schedule pursuant to Section
7.8 of one of the Other Agreements, and such amendment or supplement constitutes
or reflects an event or occurrence that would have a Material Adverse Effect on
such Other Founding Company, CSI shall give the COMPANY notice promptly after it
has knowledge thereof. If CSI and a majority of the

                                      -41-

Founding Companies consent to such amendment or supplement, which consent shall
have been deemed given by CSI or any Founding Company if no response is received
within 24 hours following receipt of notice of such amendment or supplement (or
sooner if required by the circumstances under which such consent is requested),
but the COMPANY does not give its consent, the COMPANY may terminate this
Agreement pursuant to Section 12.1(iv) hereof. In the event that the COMPANY
seeks to amend or supplement a Schedule pursuant to this Section 7.8, and CSI
and a majority of the Other Founding Companies do not consent to such amendment
or supplement, this Agreement shall be deemed terminated by mutual consent as
set forth in Section 12.1(i) hereof. In the event that CSI or NEWCO seeks to
amend or supplement a Schedule pursuant to this Section 7.8 and a majority of
the Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. No party to this Agreement shall be liable to any other party if
this Agreement shall be terminated pursuant to the provisions of this Section
7.8. No amendment of or supplement to a Schedule shall be made later than 24
hours prior to the anticipated effectiveness of the Registration Statement.

        7.9 COOPERATION IN PREPARATION OF REGISTRATION STATEMENT. The COMPANY

Underwriters all of the information concerning the COMPANY and the STOCKHOLDER
required for inclusion in, and will cooperate with CSI and the Underwriters in
the preparation of, the Registration Statement and the prospectus included
therein (including audited and unaudited financial statements, prepared in
accordance with generally accepted accounting principles, in form suitable for
inclusion in the Registration Statement). The COMPANY and the STOCKHOLDER agree
promptly to advise CSI if at any time during the period in which a prospectus
relating to the offering is required to be delivered under the Securities Act,
any information contained in the prospectus concerning the COMPANY or the
STOCKHOLDER becomes incorrect or incomplete in any material respect, and to
provide the information needed to correct such inaccuracy. Insofar as the
information relates solely to the COMPANY or the STOCKHOLDER, the COMPANY
represents and warrants as to

                                      -42-

such information with respect to itself, and each Stockholder represents and
warrants, as to such information with respect to the COMPANY and himself or
herself, that the Registration Statement will not include an untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

        7.10 FINAL FINANCIAL STATEMENTS. The COMPANY shall provide prior to the
Funding and Consummation Date, and CSI shall have had sufficient time to review
the unaudited consolidated balance sheets of the COMPANY as of the end of all
fiscal quarters following the Balance Sheet Date, and the unaudited consolidated
statement of income, cash flows and retained earnings of the COMPANY for all
fiscal quarters ended after the Balance Sheet Date, disclosing no material
adverse change in the financial condition of the COMPANY or the results of its
operations from the financial statements as of the Balance Sheet Date. Such
financial statements shall have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis throughout the
periods indicated (except as noted therein). Except as noted in such financial
statements, all of such financial statements will present fairly the results of
operations of the COMPANY for the periods indicated therein.

        7.11 FURTHER ASSURANCES. The parties hereto agree to execute and
deliver, or cause to be executed and delivered, such further instruments or
documents or take such other action as may be reasonably necessary or convenient
to carry out the transactions contemplated hereby.

        7.12 AUTHORIZED CAPITAL. CSI shall maintain its authorized capital stock
as set forth in the Registration Statement filed with the SEC except for such
changes in authorized capital stock as are made to respond to comments made by
the SEC or requirements of any exchange or automated trading system for which
application is made to register the CSI Stock.

        7.13 COMPLIANCE WITH THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF
1976 (THE "HART-SCOTT ACT"). All parties to this Agreement hereby recognize that
one or more filings under the Hart-Scott Act may be required in connection with
the transactions contemplated herein.

                                      -43-

If it is determined by the parties to this Agreement that filings under the
Hart-Scott Act are required, then: (i) each of the parties hereto agrees to
cooperate and use its best efforts to comply with the Hart-Scott Act, (ii) such
compliance by the STOCKHOLDER and the COMPANY shall be deemed a condition
precedent in addition to the conditions precedent set forth in Section 9 of this
Agreement, and such compliance by CSI and NEWCO shall be deemed a condition
precedent in addition to the conditions precedent set forth in Section 8 of this
Agreement, and (iii) the parties agree to cooperate and use their best efforts
to cause all filings required under the Hart-Scott Act to be made. If filings
under the Hart-Scott Act are required, the costs and expenses thereof (including
filing fees) shall be borne by CSI.

shall use its best efforts to have the STOCKHOLDER released from any and all
guarantees on any indebtedness that he personally guaranteed and from any and
all pledges of assets that he pledged to secure such indebtedness for the
benefit of the COMPANY, with all such guarantees on indebtedness being assumed
by CSI. In the event that CSI cannot obtain such releases from the lenders of
any such guaranteed indebtedness on or prior to 120 days subsequent to the
Funding and Consummation Date, CSI shall pay off or otherwise refinance or
retire such indebtedness. From and after the Funding and Consummation Date and
until such time as all of such indebtedness is paid off, refinanced or retired,
CSI shall maintain unencumbered funds in amounts sufficient to provide for such
pay off, refinancing or retirement, provided that CSI may use such funds for
other purposes, in its sole discretion, with the prior written consent of each
STOCKHOLDER who has not as of that time been

                                      -50-

released from his or her guarantee as described above and whose indebtedness as
described above has not as of that time been paid off, refinanced or retired.

        10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as
contemplated by this Agreement or the Registration Statement, after the Funding
and Consummation Date, CSI shall not and shall not permit any of its
subsidiaries to undertake any act that would jeopardize the tax-free status of
the organization, including without limitation:

               (a) the retirement or reacquisition, directly or indirectly, of
        all or part of the CSI Stock issued in connection with the transactions
        contemplated hereby; or

               (b) the entering into of financial arrangements for the benefit
        of the STOCKHOLDER.

        10.3   PREPARATION AND FILING OF TAX RETURNS.

               (i) The COMPANY shall, if possible, file or cause to be filed all
        separate Returns of any Acquired Party for all taxable periods that end
        on or before the Funding and Consummation Date. Notwithstanding the
        foregoing, the STOCKHOLDER shall file or cause to be filed all separate
        federal income Tax Returns (and any State and local Tax Returns filed on
        the basis similar to that of S corporations under federal income Tax
        rules) of any Acquired Party for all taxable periods that end on or
        before the Funding and Consummation Date. The STOCKHOLDER shall pay or
        cause to be paid all Tax liabilities (in excess of all amounts already
        paid with respect thereto or properly accrued or reserved with respect
        thereto on the COMPANY Financial Statements) shown by such Returns to be
        due.

               (ii) CSI shall file or cause to be filed all separate Returns of,
        or that include, any Acquired Party for all taxable periods ending after
        the Funding and Consummation Date.

               (iii) Each party hereto shall, and shall cause its subsidiaries
        and affiliates to, provide to each of the other parties hereto such
        cooperation and information as any of them reasonably may request in
        filing any Return, amended Return or claim for refund,

                                      -51-

        determining a liability for Taxes or a right to refund of Taxes or in
        conducting any audit or other proceeding in respect of Taxes. Such
        cooperation and information shall include providing copies of all
        relevant portions of relevant Returns, together with relevant
        accompanying schedules and relevant work papers, relevant documents
        relating to rulings or other determinations by Taxing Authorities and
        relevant records concerning the ownership and Tax basis of property,
        which such party may possess. Each party shall make its employees
        reasonably available on a mutually convenient basis at its cost to
        provide explanation of any documents or information so provided. Subject
        to the preceding sentence, each party required to file Returns pursuant
        to this Agreement shall bear all costs of filing such Returns.

               (iv) Each of the COMPANY, NEWCO, CSI and the STOCKHOLDER shall
        comply with the tax reporting requirements of Section 1.351-3 of the
        Treasury Regulations promulgated under the Code, and treat the
        transaction as a tax-free contribution under Section 351(a) of the Code
        subject to gain, if any, recognized on the receipt of cash or other
        property under Section 351(b) of the Code. 10.4 DIRECTORS. The persons
        named in the draft of the Registration Statement shall be

appointed as directors and elected as officers of CSI, as and to the extent set
forth in the draft of the Registration Statement, promptly following the Funding
and Consummation Date. This provision shall not imply that the STOCKHOLDERS have
any power or duty to elect officers of CSI.

        10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation to provide
replacement plans that have the same terms and provisions as the existing plans,
provided, further, that any new health insurance plan shall provide for coverage
for preexisting conditions. On the Funding and Consummation Date, the employees
of the COMPANY will be the employees of

                                      -52-

the Surviving Corporation (provided that this provision is for purposes of
clarifying that the Merger, in and of itself, will not have any impact on the
employment status of any employee and provided, further that this provision
shall not in any way limit the management rights of the Surviving Corporation or
CSI to assess workforce needs and make appropriate adjustments as necessary or
desirable within their discretion subject to applicable laws and collective
bargaining agreements).

        10.6 DIVIDENDS. If the COMPANY is an S corporation, the COMPANY may pay
to each STOCKHOLDER as a dividend the full amount of his or her "accumulated
adjustments account" (as defined in Section 1368(e) of the Code) as of the
Balance Sheet Date, and may also pay to the STOCKHOLDER as a dividend the full
amount of the COMPANY's earnings taxable to such STOCKHOLDER for the period
after the Balance Sheet Date to the Funding and Consummation Date. If the
COMPANY is a C corporation, the COMPANY may pay to the STOCKHOLDER as a dividend
the full amount of the COMPANY's earnings for the period after the Balance Sheet
Date to the Funding and Consummation Date. The COMPANY may borrow funds to the
extent necessary to make the payments contemplated by this Section 10.6 and to
the extent necessary to ensure that the COMPANY has cash on hand to adequately
fund operations on the Funding and Consummation Date.

11.     INDEMNIFICATION

        The STOCKHOLDER, CSI and NEWCO each make the following covenants that
are applicable to them, respectively:

        11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDER. The STOCKHOLDER
covenants and agrees that he will indemnify, defend, protect and hold harmless
CSI, NEWCO, the COMPANY and the Surviving Corporation at all times, from and
after the date of this Agreement until the Expiration Date, from and against all
claims, damages, actions, suits, proceedings, demands, assessments, adjustments,
costs and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by CSI, NEWCO, the
COMPANY

                                      -53-

or the Surviving Corporation as a result of or arising from (i) any breach of
the representations and warranties of the STOCKHOLDER or the COMPANY set forth
herein or on the schedules or certificates delivered in connection herewith,
(ii) any breach of any agreement on the part of the STOCKHOLDER or the COMPANY
under this Agreement, or (iii) any liability under the 1933 Act, the 1934 Act or
other Federal or state law or regulation, at common law or otherwise, arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact relating to the COMPANY or the STOCKHOLDER, and provided to CSI or
its counsel by the COMPANY or the STOCKHOLDER (but in the case of the
STOCKHOLDER, only if such statement was provided in writing) contained in the
Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to the
COMPANY or the STOCKHOLDER required to be stated therein or necessary to make
the statements therein not misleading, provided, however, that such indemnity
shall not inure to the benefit of CSI, NEWCO, the COMPANY or the Surviving
Corporation to the extent that such untrue statement (or alleged untrue
statement) was made in, or omission (or alleged omission) occurred in, any
preliminary prospectus and the STOCKHOLDER provided, in writing, corrected
information to CSI counsel and to CSI for inclusion in the final prospectus, and
such information was not so included or properly delivered.

        11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDER at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
STOCKHOLDER as a result of or arising from (i) any breach by CSI or NEWCO of
their representations and warranties set forth herein or on the schedules or
certificates attached hereto, (ii) any nonfulfillment of any agreement on the
part of CSI or NEWCO under this Agreement, (iii) any liabilities which the
STOCKHOLDER may incur due to CSI's or NEWCO's failure to be responsible

                                      -54-

for the liabilities and obligations of the COMPANY as provided in Section 1
hereof (except to the extent that CSI or NEWCO has claims against the
STOCKHOLDER by reason of such liabilities); or (iv) any liability under the 1933
Act, the 1934 Act or other Federal or state law or regulation, at common law or
otherwise, arising out of or based upon any untrue statement or alleged untrue
statement of a material fact relating to CSI, NEWCO or any of the Other Founding
Companies contained in any preliminary prospectus, the Registration Statement or
any prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or arising out of or based upon any omission or alleged omission to
state therein a material fact relating to CSI or NEWCO or any of the Other
Founding Companies required to be stated therein or necessary to make the
statements therein not misleading.

        11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified Party
of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or

                                      -55-

control. All Indemnified Parties shall use the same counsel, which shall be the
counsel selected by Indemnifying Party, provided that if counsel to the
Indemnifying Party shall have a conflict of interest that prevents counsel for
the Indemnifying Party from representing Indemnified Party, Indemnified Party
shall have the right to participate in such matter through counsel of its own
choosing and Indemnifying Party will reimburse the Indemnified Party for the
reasonable expenses of its counsel. After the Indemnifying Party has notified
the Indemnified Party of its intention to undertake to defend or settle any such
asserted liability, and for so long as the Indemnifying Party diligently pursues
such defense, the Indemnifying Party shall not be liable for any additional
legal expenses incurred by the Indemnified Party in connection with any defense
or settlement of such asserted liability, except (i) as set forth in the
preceding sentence and (ii) to the extent such participation is requested by the
Indemnifying Party, in which event the Indemnified Party shall be reimbursed by
the Indemnifying Party for reasonable additional legal expenses and
out-of-pocket expenses. If the Indemnifying Party desires to accept a final and
complete settlement of any such Third Person claim and the Indemnified Party
refuses to consent to such settlement, then the Indemnifying Party's liability
under this Section with respect to such Third Person claim shall be limited to
the amount so offered in settlement by said Third Person. Upon agreement as to
such settlement between said Third Person and the Indemnifying Party, the
Indemnifying Party shall, in exchange for a complete release from the
Indemnified Party, promptly pay to the Indemnified Party the amount agreed to in
such settlement and the Indemnified Party shall, from that moment on, bear full
responsibility for any additional costs of defense which it subsequently incurs
with respect to such claim and all additional costs of settlement or judgment.
If the Indemnifying Party does not undertake to defend such matter to which the
Indemnified Party is entitled to indemnification hereunder, or fails diligently
to pursue such defense, the Indemnified Party may undertake such defense through
counsel of its choice, at the cost and expense of the Indemnifying Party, and
the Indemnified Party may settle such matter, and the Indemnifying Party shall
reimburse the Indemnified Party for the amount paid in such settlement and any
other liabilities or expenses

                                      -56-

incurred by the Indemnified Party in connection therewith, provided, however,
that under no circumstances shall the Indemnified Party settle any Third Person
claim without the written consent of the Indemnifying Party, which consent shall
not be unreasonably withheld or delayed. All settlements hereunder shall effect
a complete release of the Indemnified Party, unless the Indemnified Party
otherwise agrees in writing. The parties hereto will make appropriate
adjustments for insurance proceeds in determining the amount of any
indemnification obligation under this Section.

        11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section
11 shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

        11.5 LIMITATIONS ON INDEMNIFICATION. CSI, NEWCO, the Surviving
Corporation and the other persons or entities indemnified pursuant to Section
11.1 or 11.2 shall not assert any claim for indemnification hereunder against
the STOCKHOLDER until such time as, and solely to the extent that, the aggregate
of all claims which such persons may have against such the STOCKHOLDER shall
exceed the greater of (a) 1.0% of the sum of the cash paid to STOCKHOLDER plus
the value of the CSI Stock delivered to STOCKHOLDER (calculated as provided in
this Section 11.5) or (b) $50,000 (the "Indemnification Threshold"). STOCKHOLDER
shall not assert any claim for indemnification hereunder against CSI or NEWCO
until such time as, and solely to the extent that, the aggregate of all claims
which STOCKHOLDER may have against CSI or NEWCO shall exceed $50,000.

        No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

                                      -57-

        Notwithstanding any other term of this Agreement, no STOCKHOLDER shall
be liable under this Section 11 for an amount which exceeds the amount of
proceeds received by such STOCKHOLDER in connection with the Merger. For
purposes of calculating the value of the CSI Stock received by a STOCKHOLDER,
CSI Stock shall be valued at its initial public offering price as set forth in
the Registration Statement. It is hereby understood and agreed that a
STOCKHOLDER may satisfy an indemnification obligation through payment of a
combination of stock and cash in proportion equal to the proportion of stock and
cash received by such STOCKHOLDER in connection with the Merger, valued as
described immediately above.

12.     TERMINATION OF AGREEMENT

        12.1 TERMINATION. This Agreement may be terminated at any time prior to
the Funding and Consummation Date solely:

        (i) by mutual consent of the boards of directors of CSI and the COMPANY;

        (ii) by the STOCKHOLDER or the COMPANY (acting through its board of
directors), on the one hand, or by CSI (acting through its board of directors),
on the other hand, if the transactions contemplated by this Agreement to take
place at the Closing shall not have been consummated by September 30, 1997,
unless the failure of such transactions to be consummated is due to the willful
failure of the party seeking to terminate this Agreement to perform any of its
obligations under this Agreement to the extent required to be performed by it
prior to or on the Funding and Consummation Date;

        (iii) by the STOCKHOLDER or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due and timely performance of any of the covenants or
agreements contained herein, and the curing of such default shall not have been
made on or before the Funding and Consummation Date or by the STOCKHOLDER, or
the COMPANY, if the conditions set forth in Section 8 hereof have not been
satisfied or waived as of the Closing Date or the Funding and Consummation Date,
as applicable,

                                      -58-

or by CSI, if the conditions set forth in Section 9 hereof have not been
satisfied or waived as of the Closing Date or the Funding and Consummation Date,
as applicable;

        (iv) pursuant to Section 7.8 hereof; or

        (v) pursuant to Section 4 hereof.

        12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.     NONCOMPETITION

        13.1 PROHIBITED ACTIVITIES. The STOCKHOLDER will not, for a period of
five (5) years following the Funding and Consummation Date, for any reason
whatsoever, directly or indirectly, for himself or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

        (i) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial capacity, whether as an employee, independent
contractor, consultant or advisor, or as a sales representative, in any heating,
ventilating or air conditioning services business in direct competition with CSI
or any of the subsidiaries thereof, within 100 miles of where the COMPANY or any
of its subsidiaries conducted business prior to the effectiveness of the Merger
(the "Territory");

        (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the subsidiaries
thereof), provided that the STOCKHOLDER shall be permitted to call upon and hire
any member of his immediate family;

                                      -59-

        (iii) call upon any person or entity which is, at that time, or which
has been, within one (1) year prior to the Funding and Consummation Date, a
customer of CSI (including the subsidiaries thereof), of the COMPANY or of any
of the Other Founding Companies within the Territory for the purpose of
soliciting or selling products or services in direct competition with CSI within
the Territory;

        (iv) call upon any prospective acquisition candidate, on the
STOCKHOLDER'S own behalf or on behalf of any competitor in the heating,
ventilation or air conditioning services business, which candidate, to the
actual knowledge of the STOCKHOLDER after due inquiry, was called upon by CSI
(including the subsidiaries thereof) or for which, to the actual knowledge of
such STOCKHOLDER after due inquiry, CSI (or any subsidiary thereof) made an
acquisition analysis, for the purpose of acquiring such entity; or

        (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

        Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit the STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

        13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to CSI for which it would
have no other adequate remedy, the STOCKHOLDER agrees that the foregoing
covenant may be enforced by CSI in the event of breach by the STOCKHOLDER, by
injunctions and restraining orders.

        13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDER in light of the activities and

                                      -60-

business of CSI (including the subsidiaries thereof) on the date of the
execution of this Agreement and the current plans of CSI.

        13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

        13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of the STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of the STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which the
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

        13.6 MATERIALITY. The COMPANY and the STOCKHOLDER hereby agree that this
covenant is a material and substantial part of this transaction.

14.     NONDISCLOSURE OF CONFIDENTIAL INFORMATION

        14.1 STOCKHOLDER. The STOCKHOLDER recognizes and acknowledges that he
had in the past, currently has, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational

                                      -61-

policies, and pricing and cost policies that are valuable, special and unique
assets of the COMPANY's, the Other Founding Companies' and/or CSI's respective
businesses. The STOCKHOLDER agrees that he will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
CSI, (b) following the Closing, such information may be disclosed by the
STOCKHOLDER as is required in the course of performing his duties for CSI or the
Surviving Corporation and (c) to counsel and other advisers, provided that such
advisers (other than counsel) agree to the confidentiality provisions of this
Section 14.1, unless (i) such information becomes known to the public generally
through no fault of the STOCKHOLDER, (ii) disclosure is required by law or the
order of any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii), the STOCKHOLDER shall,
if possible, give prior written notice thereof to CSI and provide CSI with the
opportunity to contest such disclosure, or (iii) the disclosing party reasonably
believes that such disclosure is required in connection with the defense of a
lawsuit against the disclosing party. In the event of a breach or threatened
breach by the STOCKHOLDER of the provisions of this Section, CSI shall be
entitled to an injunction restraining the STOCKHOLDER from disclosing, in whole
or in part, such confidential information. Nothing herein shall be construed as
prohibiting CSI from pursuing any other available remedy for such breach or
threatened breach, including the recovery of damages. In the event the
transactions contemplated by this Agreement are not consummated, STOCKHOLDER
shall have none of the above-mentioned restrictions on their ability to
disseminate confidential information with respect to the COMPANY.

        14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they
had in the past and currently have access to certain confidential information of
the COMPANY, such as operational policies, and pricing and cost policies that
are valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential

                                      -62-

information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, (c) to the Other Founding Companies and their representatives pursuant to
Section 7.1(a), unless (i) such information becomes known to the public
generally through no fault of CSI or NEWCO, (ii) disclosure is required by law
or the order of any governmental authority under color of law, provided, that
prior to disclosing any information pursuant to this clause (ii), CSI and NEWCO
shall, if possible, give prior written notice thereof to the COMPANY and the
STOCKHOLDER and provide the COMPANY and the STOCKHOLDER with the opportunity to
contest such disclosure, or (iii) the disclosing party reasonably believes that
such disclosure is required in connection with the defense of a lawsuit against
the disclosing party, and (d) to the public to the extent necessary or advisable
in connection with the filing of the Registration Statement and the IPO and the
securities laws applicable thereto and to the operation of CSI as a publicly
held entity after the IPO. In the event of a breach or threatened breach by CSI
or NEWCO of the provisions of this Section, the COMPANY and the STOCKHOLDER
shall be entitled to an injunction restraining CSI and NEWCO from disclosing, in
whole or in part, such confidential information. Nothing herein shall be
construed as prohibiting the COMPANY and the STOCKHOLDER from pursuing any other
available remedy for such breach or threatened breach, including the recovery of
damages.

        14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

        14.4 SURVIVAL. The obligations of the parties under this Article 14
shall survive the termination of this Agreement for a period of five years from
the Funding and Consummation Date.

                                      -63-

15.     TRANSFER RESTRICTIONS

        15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDER or family members, the trustees of
which so agree), for a period of one year from the Closing, except pursuant to
Section 17 hereof, the STOCKHOLDER shall not sell, assign, exchange, transfer,
encumber, pledge, distribute, appoint, or otherwise dispose of any shares of CSI
Stock as described in Section 3.1 received by the STOCKHOLDER in the Merger. The
certificates evidencing the CSI Stock delivered to the STOCKHOLDER pursuant to
Section 3 of this Agreement will bear a legend substantially in the form set
forth below and containing such other information as CSI may deem necessary or
appropriate: THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR
OTHERWISE DISPOSED OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO
ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE,
DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION PRIOR TO THE FIRST ANNIVERSARY OF
CLOSING DATE. UPON THE WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE
ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH
THE TRANSFER AGENT) AFTER THE DATE SPECIFIED ABOVE.

16.     FEDERAL SECURITIES ACT REPRESENTATIONS

        16.1 COMPLIANCE WITH LAW. The STOCKHOLDER acknowledges that the shares
of CSI Stock to be delivered to the STOCKHOLDER pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and may not be resold without compliance with the Act. The CSI Stock
to be acquired by the STOCKHOLDER pursuant

                                      -64-

to this Agreement is being acquired solely for his own respective accounts, for
investment purposes only, and with no present intention of distributing, selling
or otherwise disposing of it in connection with a distribution. The STOCKHOLDER
covenants, warrants and represents that none of the shares of CSI Stock issued
to the STOCKHOLDER will be offered, sold, assigned, pledged, hypothecated,
transferred or otherwise disposed of except after full compliance with all of
the applicable provisions of the Act and the rules and regulations of the SEC.
All the CSI Stock shall bear the following legend in addition to the legend
required under Section 15 of this Agreement:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

        16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDER is able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and has such
knowledge and experience in financial and business matters that he is capable of
evaluating the merits and risks of the proposed investment in the CSI Stock. The
STOCKHOLDER has had an adequate opportunity to ask questions and receive answers
from the officers of CSI concerning any and all matters relating to the
transactions described herein including, without limitation, the background and
experience of the current and proposed officers and directors of CSI, the plans
for the operations of the business of CSI, the business, operations and
financial condition of the Founding Companies other than the COMPANY, and any
plans for additional acquisitions and the like. The STOCKHOLDER has asked any
and all questions in the nature described in the preceding sentence and all
questions have been answered to his satisfaction.

17.     REGISTRATION RIGHTS

                                      -65-

        17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
the STOCKHOLDER prompt written notice of its intent to do so. Upon the written
request of the STOCKHOLDER given within 30 days after receipt of such notice,
CSI shall cause to be included in such registration all of the CSI Stock issued
to the STOCKHOLDER pursuant to this Agreement (including any stock issued as (or
issuable upon the conversion or exchange of any convertible security, warrant,
right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) which the STOCKHOLDER requests, provided that CSI shall have the right to
reduce the number of shares included in such registration to the extent that
inclusion of such shares could, in the opinion of tax counsel to CSI or its
independent auditors, jeopardize the status of the transactions contemplated
hereby and by the Registration Statement as a tax-free organization. In
addition, if CSI is advised in writing in good faith by any managing underwriter
of an underwritten offering of the securities being offered pursuant to any
registration statement under this Section 17.1 that the number of shares to be
sold by persons other than CSI is greater than the number of such shares which
can be offered without adversely affecting the offering, CSI may reduce pro rata
the number of shares offered for the accounts of such persons (based upon the
number of shares held by such person) to a number deemed satisfactory by such
managing underwriter, provided, that, for each such offering made by CSI after
the IPO, such reduction shall be made first by reducing the number of shares to
be sold by persons other than CSI, the STOCKHOLDER and the stockholders of the
Other Founding Companies (collectively, the STOCKHOLDER and the stockholders of
the other Founding Companies being referred to herein as the "Founding
Stockholders"), and thereafter, if a further reduction is required, by reducing
the number of shares to be sold by the Founding Stockholders.

                                      -66-

        17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year
after the Closing and prior to the date three years after the Closing, the
holders of a majority of the shares of CSI Stock issued to the Founding
Stockholders pursuant to this Agreement and the Other Agreements which have not
been previously registered or sold and which are not entitled to be sold under
Rule 144(k) (or any similar or successor provision) promulgated under the 1933
Act may request in writing that CSI file a registration statement under the 1933
Act covering the registration of the shares of CSI Stock issued to the
STOCKHOLDER pursuant to this Agreement and the Other Agreements (including any
stock issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) then held by such Founding Stockholders (a "Demand
Registration"). Within ten (10) days of the receipt of such request, CSI shall
give written notice of such request to all other Founding Stockholders and
shall, as soon as practicable but in no event later than 45 days after notice
from the STOCKHOLDER, file and use its best efforts to cause to become effective
a registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

        Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the date on which CSI
would otherwise be required to make such filing pursuant to the foregoing
paragraph.

        If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective

                                      -67-

date of such registration unless CSI is no longer proceeding diligently to
effect such registration; provided that CSI shall provide the Founding
Stockholders the right to participate in such public offering pursuant to, and
subject to, Section 17.1 hereof.

        17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with
the registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

        17.4 UNDERWRITING AGREEMENT. In connection with each registration
pursuant to Sections 17.1 and 17.2 covering an underwritten registered offering,
CSI and each participating holder agree to enter into a written agreement with
the managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
managing underwriters and companies of CSI's size and investment stature,
including indemnification.

        17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by the STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to the STOCKHOLDER.

                                      -68-

        17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

               (i) make and keep public information regarding CSI available as
        those terms are understood and defined in Rule 144 under the 1933 Act
        for a period of four years beginning 90 days following the effective
        date of the Registration Statement;

               (ii) file with the SEC in a timely manner all reports and other
        documents required of CSI under the 1933 Act and the 1934 Act at any
        time after it has become subject to such reporting requirements; and

               (iii) so long as a STOCKHOLDER owns any restricted CSI Common
        Stock, furnish to each STOCKHOLDER forthwith upon written request a
        written statement by CSI as to its compliance with the reporting
        requirements of Rule 144 (at any time from and after 90 days following
        the effective date of the Registration Statement, and of the 1933 Act
        and the 1934 Act (at any time after it has become subject to such
        reporting requirements), a copy of the most recent annual or quarterly
        report of CSI, and such other reports and documents so filed as a
        STOCKHOLDER may reasonably request in availing itself of any rule or
        regulation of the SEC allowing a STOCKHOLDER to sell any such shares
        without registration.

        18.    GENERAL

        18.1 COOPERATION. The COMPANY, STOCKHOLDER, CSI and NEWCO shall each
deliver or cause to be delivered to the other on the Funding and Consummation
Date, and at such other times and places as shall be reasonably agreed to, such
additional instruments as the other may reasonably request for the purpose of
carrying out this Agreement. The COMPANY will cooperate and use its reasonable
efforts to have the present officers, directors and employees of the COMPANY
cooperate with CSI on and after the Funding and Consummation Date in furnishing

                                      -69-

return filing obligations, actions, proceedings, arrangements or disputes of any

and Consummation Date.

        18.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law) and shall be
binding upon and shall inure to the benefit of the parties hereto, the
successors of CSI, and the heirs and legal representatives of the STOCKHOLDER.

        18.3 ENTIRE AGREEMENT. This Agreement (including the schedules, exhibits
and annexes attached hereto) and the documents delivered pursuant hereto
constitute the entire agreement and understanding among the STOCKHOLDER, the
COMPANY, NEWCO and CSI and supersede any prior agreement and understanding
relating to the subject matter of this Agreement. This Agreement, upon

enforceable in accordance with its terms and may be modified or amended only by
a written instrument executed by the STOCKHOLDER, the COMPANY, NEWCO and CSI,
acting through their respective officers or trustees, duly authorized by their
respective Boards of Directors. Any disclosure made on any Schedule delivered
pursuant hereto shall be deemed to have been disclosed for purposes of any other
Schedule required hereby, provided that the COMPANY shall make a good faith
effort to cross reference disclosure, as necessary or advisable, between related
Schedules.

        18.4 COUNTERPARTS. This Agreement may be executed simultaneously in two
(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

        18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each
party represents and warrants that it employed no broker or agent in connection
with this transaction and agrees to indemnify the other parties hereto against
all loss, cost, damages or expense arising out of claims for fees or commission
of brokers employed or alleged to have been employed by such indemnifying party.

                                      -70-

        18.6 EXPENSES. Whether or not the transactions herein contemplated shall

similar taxes and fees ("Transfer Taxes") imposed in connection with the Merger,
other than Transfer Taxes, if any, imposed by the State of Delaware. The
STOCKHOLDER shall file all necessary documentation and Returns with respect to

the COMPANY or CSI, will pay all taxes due upon receipt of the consideration
payable pursuant to Section 2 hereof, and will assume all tax risks and
liabilities of the STOCKHOLDER in connection with the transactions contemplated
hereby.

entirety or are fully reflected on the balance sheet of the COMPANY as of the
Balance Sheet Date.

      ERISA or to the Internal Revenue Service for any excise tax or penalty, or
      being subject to any statutory lien to secure payment of any such
      liability) with respect to any plan now or heretofore maintained or
      contributed to by any entity other than the COMPANY that is, or at any
      time was, a member of a "controlled group" (as defined in Section
      412(n)(6)(B) of the Code) that includes the COMPANY.

agreements are listed on Schedule 7.6 and copies thereof shall be attached
thereto.

      7.7 NOTIFICATION OF CERTAIN MATTERS. The STOCKHOLDERS and the COMPANY
shall give prompt notice to CSI of (i) the occurrence or non-occurrence of any
event the occurrence or non-occurrence of which would be likely to cause any
representation or warranty of the COMPANY or the STOCKHOLDERS contained herein
to be untrue or inaccurate in any material respect at or

                                      -41-

prior to the Closing and (ii) any material failure of any STOCKHOLDER or the
COMPANY to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by such person hereunder. CSI and NEWCO shall give
prompt notice to the COMPANY of (i) the occurrence or non-occurrence of any
event the occurrence or non-occurrence of which would be likely to cause any
representation or warranty of CSI or NEWCO contained herein to be untrue or
inaccurate in any material respect at or prior to the Closing and (ii) any
material failure of CSI or NEWCO to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder. The

modify the representations or warranties hereunder of the party delivering such
notice, which modification may only be made pursuant to Section 7.8, (ii) modify
the conditions set forth in Sections 8 and 9, or (iii) limit or otherwise affect
the remedies available hereunder to the party receiving such notice.

      7.8 AMENDMENT OF SCHEDULES. Each party hereto agrees that, with respect to
the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the COMPANY that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless CSI and
a majority of the Founding Companies other than the COMPANY consent to such
amendment or supplement; and provided further, that no amendment or supplement
to a Schedule prepared by CSI or NEWCO that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless a
majority of

                                      -42-

the Founding Companies consent to such amendment or supplement. For all purposes
of this Agreement, including without limitation for purposes of determining
whether the conditions set forth in Sections 8.1 and 9.1 have been fulfilled,
the Schedules hereto shall be deemed to be the Schedules as amended or
supplemented pursuant to this Section 7.8. In the event that one of the Other
Founding Companies seeks to amend or supplement a Schedule pursuant to Section
7.8 of one of the Other Agreements, and such amendment or supplement constitutes
or reflects an event or occurrence that would have a Material Adverse Effect on
such Other Founding Company, CSI shall give the COMPANY notice promptly after it
has knowledge thereof. If CSI and a majority of the Founding Companies consent
to such amendment or supplement, which consent shall have been deemed given by
CSI or any Founding Company if no response is received within 24 hours following
receipt of notice of such amendment or supplement (or sooner if required by the
circumstances under which such consent is requested), but the COMPANY does not
give its consent, the COMPANY may terminate this Agreement pursuant to Section
12.1(iv) hereof. In the event that the COMPANY seeks to amend or supplement a
Schedule pursuant to this Section 7.8, and CSI and a majority of the Other
Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. In the event that CSI or NEWCO seeks to amend or supplement a
Schedule pursuant to this Section 7.8 and a majority of the Founding Companies
do not consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the
anticipated effectiveness of the Registration Statement.

      7.9 COOPERATION IN PREPARATION OF REGISTRATION STATEMENT. The COMPANY and
STOCKHOLDERS shall furnish or cause to be furnished to CSI and the Underwriters
all of the information concerning the COMPANY and the STOCKHOLDERS required for
inclusion in, and will cooperate with CSI and the Underwriters in the
preparation of, the Registration Statement and

                                      -43-

the prospectus included therein (including audited and unaudited financial
statements, prepared in accordance with generally accepted accounting
principles, in form suitable for inclusion in the Registration Statement). The
COMPANY and the STOCKHOLDERS agree promptly to advise CSI if at any time during
the period in which a prospectus relating to the offering is required to be
delivered under the Securities Act, any information contained in the prospectus
concerning the COMPANY or the STOCKHOLDERS becomes incorrect or incomplete in
any material respect, and to provide the information needed to correct such
inaccuracy. Insofar as the information relates solely to the COMPANY or the
STOCKHOLDERS, the COMPANY represents and warrants as to such information with
respect to itself, and each Stockholder represents and warrants, as to such
information with respect to the COMPANY and himself or herself, that the
Registration Statement will not include an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

      7.10 FINAL FINANCIAL STATEMENTS. The COMPANY shall provide prior to the
Funding and Consummation Date, and CSI shall have had sufficient time to review
the unaudited consolidated balance sheets of the COMPANY as of the end of all
fiscal quarters following the Balance Sheet Date, and the unaudited consolidated
statement of income, cash flows and retained earnings of the COMPANY for all
fiscal quarters ended after the Balance Sheet Date, disclosing no material
adverse change in the financial condition of the COMPANY or the results of its
operations from the financial statements as of the Balance Sheet Date. Such
financial statements shall have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis throughout the
periods indicated (except as noted therein). Except as noted in such financial
statements, all of such financial statements will present fairly the results of
operations of the COMPANY for the periods indicated therein.

      7.11 FURTHER ASSURANCES. The parties hereto agree to execute and deliver,

take such other action as may be reasonably necessary or convenient to carry out
the transactions contemplated hereby.

      7.12 AUTHORIZED CAPITAL. CSI shall maintain its authorized capital stock
as set forth in the Registration Statement filed with the SEC except for such
changes in authorized capital stock as are made to respond to comments made by
the SEC or requirements of any exchange or automated trading system for which
application is made to register the CSI Stock.

      7.13 COMPLIANCE WITH THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF
1976 (THE "HART-SCOTT ACT"). All parties to this Agreement hereby recognize that
one or more filings under the Hart-Scott Act may be required in connection with
the transactions contemplated herein. If it is determined by the parties to this
Agreement that filings under the Hart-Scott Act are required, then: (i) each of
the parties hereto agrees to cooperate and use its best efforts to comply with
the Hart-Scott Act, (ii) such compliance by the STOCKHOLDERS and the COMPANY
shall be deemed a condition precedent in addition to the conditions precedent
set forth in Section 9 of this Agreement, and such compliance by CSI and NEWCO
shall be deemed a condition precedent in addition to the conditions precedent
set forth in Section 8 of this Agreement, and (iii) the parties agree to
cooperate and use their best efforts to cause all filings required under the
Hart-Scott Act to be made. If filings under the Hart-Scott Act are required, the
costs and expenses thereof (including filing fees) shall be borne by CSI.

                                      -51-

funds in amounts sufficient to provide for such pay off, refinancing or
retirement, provided that CSI may use such funds for other purposes, in its sole
discretion, with the prior written consent of each STOCKHOLDER who has not as of

      foregoing, the STOCKHOLDERS shall file or cause to be filed all separate
      federal income Tax Returns of any Acquired Party for all taxable periods
      that end on or before the Funding and Consummation Date. Each STOCKHOLDER
      shall pay or cause to be paid all Tax liabilities (in excess of all
      amounts already paid with respect thereto or properly accrued or reserved
      with respect thereto on the COMPANY Financial Statements) shown by such
      Returns to be due.

            (ii) CSI shall file or cause to be filed all separate Returns of, or
      that include, any Acquired Party for all taxable periods ending after the

      filing any Return, amended Return or claim for refund, determining a

      audit or other proceeding in respect of Taxes. Such cooperation and
      information shall include providing copies of all relevant portions of
      relevant Returns, together with relevant accompanying schedules and
      relevant work papers, relevant documents relating to rulings or other
      determinations by Taxing Authorities and relevant records concerning the
      ownership and Tax basis of property, which such party may possess. Each
      party shall make its employees reasonably available on a mutually
      convenient basis at its cost to provide explanation of any documents or
      information so provided. Subject to the preceding sentence, each party
      required to file Returns pursuant to this Agreement shall bear all costs
      of filing such Returns.

            (iv) Each of the COMPANY, NEWCO, CSI and each STOCKHOLDER shall
      comply with the tax reporting requirements of Section 1.351-3 of the
      Treasury Regulations promulgated under the Code, and treat the transaction
      as a tax-free contribution under Section 351(a) of the Code subject to
      gain, if any, recognized on the receipt of cash or other property under
      Section 351(b) of the Code subject to gain, if any, recognized on the

Statement shall be appointed as directors and elected as officers of CSI, as and
to the extent set forth in the draft of the Registration Statement, promptly
following the Funding and Consummation Date. This provision shall not imply that
the STOCKHOLDERS have any power or duty to elect officers of CSI.

      10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is

                                      -53-

applicable to CSI and all of its then existing subsidiaries, provided that CSI
shall have no obligation to provide replacement plans that have the same terms
and provisions as the existing plans, provided, further, that any new health
insurance plan shall provide for coverage for preexisting conditions. On the
Funding and Consummation Date, the employees of the COMPANY will be the
employees of the Surviving Corporation (provided that this provision is for
purposes of clarifying that the Merger, in and of itself, will not have any
impact on the employment status of any employee and provided, further that this
provision shall not in any way limit the management rights of the Surviving
Corporation or CSI to assess workforce needs and make appropriate adjustments as
necessary or desirable within their discretion subject to applicable laws and
collective bargaining agreements).

Federal or state law or regulation, at common law or otherwise, arising out of
or based upon any untrue statement or alleged untrue statement of a material

                                      -54-

fact relating to the COMPANY or the STOCKHOLDERS, and provided to CSI or its
counsel by the COMPANY or the STOCKHOLDERS (but in the case of the STOCKHOLDERS,
only if such statement was provided in writing) contained in the Registration
Statement or any prospectus forming a part thereof, or any amendment thereof or
supplement thereto, or arising out of or based upon any omission or alleged
omission to state therein a material fact relating to the COMPANY or the
STOCKHOLDERS required to be stated therein or necessary to make the statements
therein not misleading, provided, however, that such indemnity shall not inure
to the benefit of CSI, NEWCO, the COMPANY or the Surviving Corporation to the
extent that such untrue statement (or alleged untrue statement) was made in, or
omission (or alleged omission) occurred in, any preliminary prospectus and the
STOCKHOLDERS provided, in writing, corrected information to CSI counsel and to
CSI for inclusion in the final prospectus, and such information was not so
included or properly delivered, and provided further, that no STOCKHOLDER shall
be liable for any indemnification obligation pursuant to this Section 11.1 to
the extent attributable to a breach of any representation, warranty or agreement
made herein individually by any other STOCKHOLDER.

      11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDERS at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
STOCKHOLDERS as a result of or arising from (i) any breach by CSI or NEWCO of
their representations and warranties set forth herein or on the schedules or
certificates attached hereto, (ii) any nonfulfillment of any agreement on the
part of CSI or NEWCO under this Agreement, (iii) any liabilities which the
STOCKHOLDERS may incur due to CSI's or NEWCO's failure to be responsible for the
liabilities and obligations of the COMPANY as provided in Section 1 hereof
(except to the extent that CSI or NEWCO has claims against the STOCKHOLDERS by
reason of such liabilities); or (iv) any liability under the 1933 Act, the 1934
Act or other Federal or state law

                                      -55-

or regulation, at common law or otherwise, arising out of or based upon any
untrue statement or alleged untrue statement of a material fact relating to CSI,
NEWCO or any of the Other Founding Companies contained in any preliminary
prospectus, the Registration Statement or any prospectus forming a part thereof,
or any amendment thereof or supplement thereto, or arising out of or based upon
any omission or alleged omission to state therein a material fact relating to
CSI or NEWCO or any of the Other Founding Companies required to be stated
therein or necessary to make the statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has knowledge of any claim by a
person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified Party
of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or control. All Indemnified Parties shall use the same counsel, which
shall be the counsel selected by Indemnifying Party, provided that if counsel to
the Indemnifying Party shall have a conflict of interest that prevents counsel
for the Indemnifying Party from representing Indemnified Party,

                                      -56-

Indemnified Party shall have the right to participate in such matter through
counsel of its own choosing and Indemnifying Party will reimburse the
Indemnified Party for the reasonable expenses of its counsel. After the
Indemnifying Party has notified the Indemnified Party of its intention to
undertake to defend or settle any such asserted liability, and for so long as
the Indemnifying Party diligently pursues such defense, the Indemnifying Party
shall not be liable for any additional legal expenses incurred by the
Indemnified Party in connection with any defense or settlement of such asserted
liability, except (i) as set forth in the preceding sentence and (ii) to the
extent such participation is requested by the Indemnifying Party, in which event
the Indemnified Party shall be reimbursed by the Indemnifying Party for
reasonable additional legal expenses and out-of-pocket expenses. If the
Indemnifying Party desires to accept a final and complete settlement of any such
Third Person claim and the Indemnified Party refuses to consent to such
settlement, then the Indemnifying Party's liability under this Section with
respect to such Third Person claim shall be limited to the amount so offered in
settlement by said Third Person. Upon agreement as to such settlement between
said Third Person and the Indemnifying Party, the Indemnifying Party shall, in
exchange for a complete release from the Indemnified Party, promptly pay to the
Indemnified Party the amount agreed to in such settlement and the Indemnified
Party shall, from that moment on, bear full responsibility for any additional
costs of defense which it subsequently incurs with respect to such claim and all
additional costs of settlement or judgment. If the Indemnifying Party does not
undertake to defend such matter to which the Indemnified Party is entitled to
indemnification hereunder, or fails diligently to pursue such defense, the
Indemnified Party may undertake such defense through counsel of its choice, at
the cost and expense of the Indemnifying Party, and the Indemnified Party may
settle such matter, and the Indemnifying Party shall reimburse the Indemnified
Party for the amount paid in such settlement and any other liabilities or
expenses incurred by the Indemnified Party in connection therewith, provided,
however, that under no circumstances shall the Indemnified Party settle any
Third Person claim without the written consent of the Indemnifying Party, which
consent shall not be unreasonably withheld or delayed. All

                                      -57-

settlements hereunder shall effect a complete release of the Indemnified Party,
unless the Indemnified Party otherwise agrees in writing. The parties hereto
will make appropriate adjustments for insurance proceeds in determining the
amount of any indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section 11
shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

      11.5 LIMITATIONS ON INDEMNIFICATION. CSI, NEWCO, the Surviving Corporation
and the other persons or entities indemnified pursuant to Section 11.1 or 11.2
shall not assert any claim for indemnification hereunder against the
STOCKHOLDERS until such time as, and solely to the extent that, the aggregate of
all claims which such persons may have against such the STOCKHOLDERS shall
exceed the greater of (a) 1.0% of the sum of the cash paid to STOCKHOLDERS plus
the value of the CSI Stock delivered to STOCKHOLDERS (calculated as provided in
this Section 11.5) or (b) $50,000 (the "Indemnification Threshold").
STOCKHOLDERS shall not assert any claim for indemnification hereunder against
CSI or NEWCO until such time as, and solely to the extent that, the aggregate of
all claims which STOCKHOLDERS may have against CSI or NEWCO shall exceed
$50,000.

      No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

      Notwithstanding any other term of this Agreement, no STOCKHOLDER shall be
liable under this Section 11 for an amount which exceeds the amount of proceeds
received by such STOCKHOLDER in connection with the Merger. For purposes of
calculating the value of the CSI Stock received by a STOCKHOLDER, CSI Stock
shall be valued at its initial public offering price

                                      -58-

as set forth in the Registration Statement. It is hereby understood and agreed
that a STOCKHOLDER may satisfy an indemnification obligation through payment of
a combination of stock and cash in proportion equal to the proportion of stock
and cash received by such STOCKHOLDER in connection with the Merger, valued as
described immediately above.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION.This Agreement may be terminated at any time prior to the
Funding and Consummation Date solely:

      (i) by mutual consent of the boards of directors of CSI and the COMPANY;

      (ii) by the STOCKHOLDERS or the COMPANY (acting through its board of
directors), on the one hand, or by CSI (acting through its board of directors),
on the other hand, if the transactions contemplated by this Agreement to take
place at the Closing shall not have been consummated by September 30, 1997,
unless the failure of such transactions to be consummated is due to the willful
failure of the party seeking to terminate this Agreement to perform any of its
obligations under this Agreement to the extent required to be performed by it
prior to or on the Funding and Consummation Date;

      (iii) by the STOCKHOLDERS or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due and timely performance of any of the covenants or
agreements contained herein, and the curing of such default shall not have been
made on or before the Funding and Consummation Date or by the STOCKHOLDERS or
the COMPANY, if the conditions set forth in Section 8 hereof have not been
satisfied or waived as of the Closing Date or the Funding and Consummation Date,
as applicable, or by CSI, if the conditions set forth in Section 9 hereof have
not been satisfied or waived as of the Closing Date or the Funding and
Consummation Date, as applicable;

      (iv)  pursuant to Section 7.8 hereof; or

      (v)   pursuant to Section 4 hereof.

                                      -59-

      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. The STOCKHOLDERS will not, for a period of
five (5) years following the Funding and Consummation Date, for any reason
whatsoever, directly or indirectly, for themselves or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

      (i) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial capacity, whether as an employee, independent
contractor, consultant or advisor, or as a sales representative, in any heating,
ventilating or air conditioning services business in direct competition with CSI
or any of the subsidiaries thereof, within 100 miles of where the COMPANY or any
of its subsidiaries conducted business prior to the effectiveness of the Merger
(the "Territory");

      (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the subsidiaries
thereof), provided that each STOCKHOLDER shall be permitted to call upon and
hire any member of his or her immediate family;

      (iii) call upon any person or entity which is, at that time, or which has
been, within one (1) year prior to the Funding and Consummation Date, a customer
of CSI (including the subsidiaries thereof), of the COMPANY or of any of the
Other Founding Companies within the Territory for the

                                      -60-

purpose of soliciting or selling products or services in direct competition with
CSI within the Territory;

      (iv) call upon any prospective acquisition candidate, on any STOCKHOLDER's
own behalf or on behalf of any competitor in the heating, ventilation or air
conditioning services business, which candidate, to the actual knowledge of such
STOCKHOLDER after due inquiry, was called upon by CSI (including the
subsidiaries thereof) or for which, to the actual knowledge of such STOCKHOLDER
after due inquiry, CSI (or any subsidiary thereof) made an acquisition analysis,
for the purpose of acquiring such entity; or

      (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to CSI for which it would
have no other adequate remedy, each STOCKHOLDER agrees that the foregoing
covenant may be enforced by CSI in the event of breach by such STOCKHOLDER, by
injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDERS in light of the activities and business of CSI (including the
subsidiaries thereof) on the date of the execution of this Agreement and the
current plans of CSI.

                                      -61-

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of each STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which such
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

      13.6 MATERIALITY. The COMPANY and the STOCKHOLDERS hereby agree that this
covenant is a material and substantial part of this transaction.

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1 STOCKHOLDERS. The STOCKHOLDERS recognize and acknowledge that they
had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. The

                                      -62-

STOCKHOLDERS agree that they will not disclose such confidential information to
any person, firm, corporation, association or other entity for any purpose or
reason whatsoever, except (a) to authorized representatives of CSI, (b)
following the Closing, such information may be disclosed by the STOCKHOLDERS as
is required in the course of performing their duties for CSI or the Surviving
Corporation and (c) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, unless (i) such information becomes known to the public generally through
no fault of the STOCKHOLDERS, (ii) disclosure is required by law or the order of
any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii), the STOCKHOLDERS shall,
if possible, give prior written notice thereof to CSI and provide CSI with the
opportunity to contest such disclosure, or (iii) the disclosing party reasonably
believes that such disclosure is required in connection with the defense of a
lawsuit against the disclosing party. In the event of a breach or threatened
breach by any of the STOCKHOLDERS of the provisions of this Section, CSI shall
be entitled to an injunction restraining such STOCKHOLDERS from disclosing, in
whole or in part, such confidential information. Nothing herein shall be
construed as prohibiting CSI from pursuing any other available remedy for such
breach or threatened breach, including the recovery of damages. In the event the
transactions contemplated by this Agreement are not consummated, STOCKHOLDERS
shall have none of the above-mentioned restrictions on their ability to
disseminate confidential information with respect to the COMPANY.

      14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they had
in the past and currently have access to certain confidential information of the
COMPANY, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other

                                      -63-

advisers, provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 14.1, (c) to the Other Founding
Companies and their representatives pursuant to Section 7.1(a), unless (i) such
information becomes known to the public generally through no fault of CSI or
NEWCO, (ii) disclosure is required by law or the order of any governmental
authority under color of law, provided, that prior to disclosing any information
pursuant to this clause (ii), CSI and NEWCO shall, if possible, give prior
written notice thereof to the COMPANY and the STOCKHOLDERS and provide the
COMPANY and the STOCKHOLDERS with the opportunity to contest such disclosure, or
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, and
(d) to the public to the extent necessary or advisable in connection with the
filing of the Registration Statement and the IPO and the securities laws
applicable thereto and to the operation of CSI as a publicly held entity after
the IPO. In the event of a breach or threatened breach by CSI or NEWCO of the
provisions of this Section, the COMPANY and the STOCKHOLDERS shall be entitled
to an injunction restraining CSI and NEWCO from disclosing, in whole or in part,
such confidential information. Nothing herein shall be construed as prohibiting
the COMPANY and the STOCKHOLDERS from pursuing any other available remedy for
such breach or threatened breach, including the recovery of damages.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Funding and Consummation Date.

                                      -64-

15.   TRANSFER RESTRICTIONS

      15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDERS or family members, the trustees
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the STOCKHOLDERS shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of CSI Stock as described in Section 3.1 received by the STOCKHOLDERS in
the Merger. The certificates evidencing the CSI Stock delivered to the
STOCKHOLDERS pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as CSI may deem necessary or appropriate: THE SHARES REPRESENTED BY THIS
CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED,
PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL
NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE,
TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION
PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE WRITTEN REQUEST OF THE
HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND
(AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED
ABOVE.

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The STOCKHOLDERS acknowledge that the shares of
CSI Stock to be delivered to the STOCKHOLDERS pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and therefore may not be resold without compliance with the Act. The
CSI Stock to be acquired by such STOCKHOLDERS

                                      -65-

pursuant to this Agreement is being acquired solely for their own respective
accounts, for investment purposes only, and with no present intention of
distributing, selling or otherwise disposing of it in connection with a
distribution. The STOCKHOLDERS covenant, warrant and represent that none of the
shares of CSI Stock issued to such STOCKHOLDERS will be offered, sold, assigned,
pledged, hypothecated, transferred or otherwise disposed of except after full
compliance with all of the applicable provisions of the Act and the rules and
regulations of the SEC. All the CSI Stock shall bear the following legend in
addition to the legend required under Section 15 of this Agreement: THE SHARES
REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
(THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER HEREOF
COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

      16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDERS are able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and have
such knowledge and experience in financial and business matters that they are
capable of evaluating the merits and risks of the proposed investment in the CSI
Stock. The STOCKHOLDERS party hereto have had an adequate opportunity to ask
questions and receive answers from the officers of CSI concerning any and all
matters relating to the transactions described herein including, without
limitation, the background and experience of the current and proposed officers
and directors of CSI, the plans for the operations of the business of CSI, the
business, operations and financial condition of the Founding Companies other
than the COMPANY, and any plans for additional acquisitions and the like. The
STOCKHOLDERS have asked any and all questions in the nature described in the
preceding sentence and all questions have been answered to their satisfaction.

                                      -66-

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
each of the STOCKHOLDERS prompt written notice of its intent to do so. Upon the
written request of any of the STOCKHOLDERS given within 30 days after receipt of
such notice, CSI shall cause to be included in such registration all of the CSI
Stock issued to the STOCKHOLDERS pursuant to this Agreement (including any stock
issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) which any such STOCKHOLDER requests, provided that CSI shall
have the right to reduce the number of shares included in such registration to
the extent that inclusion of such shares could, in the opinion of tax counsel to
CSI or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Registration Statement as a tax-free
organization. In addition, if CSI is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1 that the number
of shares to be sold by persons other than CSI is greater than the number of
such shares which can be offered without adversely affecting the offering, CSI
may reduce pro rata the number of shares offered for the accounts of such
persons (based upon the number of shares held by such person) to a number deemed
satisfactory by such managing underwriter, provided, that, for each such
offering made by CSI after the IPO, such reduction shall be made first by
reducing the number of shares to be sold by persons other than CSI, the
STOCKHOLDERS and the stockholders of the Other Founding Companies (collectively,
the STOCKHOLDERS and the stockholders of the other Founding Companies being
referred to herein as the "Founding Stockholders"), and thereafter, if a

                                      -67-

further reduction is required, by reducing the number of shares to be sold by
the Founding Stockholders.

      17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year after
the Closing and prior to the date three years after the Closing, the holders of
a majority of the shares of CSI Stock issued to the Founding Stockholders
pursuant to this Agreement and the Other Agreements which have not been
previously registered or sold and which are not entitled to be sold under Rule
144(k) (or any similar or successor provision) promulgated under the 1933 Act
may request in writing that CSI file a registration statement under the 1933 Act
covering the registration of the shares of CSI Stock issued to the STOCKHOLDERS
pursuant to this Agreement and the Other Agreements (including any stock issued
as (or issuable upon the conversion or exchange of any convertible security,
warrant, right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) then held by such Founding Stockholders (a "Demand Registration"). Within
ten (10) days of the receipt of such request, CSI shall give written notice of
such request to all other Founding Stockholders and shall, as soon as
practicable but in no event later than 45 days after notice from any
STOCKHOLDER, file and use its best efforts to cause to become effective a
registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

      Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the date on which CSI
would otherwise be required to make such filing pursuant to the foregoing
paragraph.

      If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of

                                      -68-

any of its securities in a public offering under the 1933 Act, no registration
of the Founding Stockholders' CSI Stock shall be initiated under this Section
17.2 until 90 days after the effective date of such registration unless CSI is
no longer proceeding diligently to effect such registration; provided that CSI
shall provide the Founding Stockholders the right to participate in such public
offering pursuant to, and subject to, Section 17.1 hereof.

      17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with the
registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold

under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Sections 17.1 and 17.2 covering an underwritten registered offering, CSI and
each participating holder agree to enter into a written agreement with the
managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
managing underwriters and companies of CSI's size and investment stature,
including indemnification.

      17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by any STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated

      17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

            (i) make and keep public information regarding CSI available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of CSI under the 1933 Act and the 1934 Act at any time
      after it has become subject to such reporting requirements; and

            (iii) so long as a STOCKHOLDER owns any restricted CSI Common Stock,
      furnish to each STOCKHOLDER forthwith upon written request a written
      statement by CSI as to its compliance with the reporting requirements of
      Rule 144 (at any time from and after 90 days following the effective date
      of the Registration Statement, and of the 1933 Act and the 1934 Act (any
      time after it has become subject to such reporting requirements), a copy
      of the most recent annual or quarterly report of CSI, and such other
      reports and documents so filed as a STOCKHOLDER may reasonably request in
      availing itself of any rule or regulation of the SEC allowing a
      STOCKHOLDER to sell any such shares without registration.

other applicable federal, state and local statutes, ordinances and regulations.

      All accrued contribution obligations of COMPANY or any Subsidiary with
respect to any plan listed on Schedule 5.19 have either been fulfilled in their
entirety or are fully reflected on the balance sheet of the COMPANY as of the
Balance Sheet Date.

Service to be so qualified, and copies of such determination letters are
included as part of Schedule 5.19 hereof. Except as disclosed on Schedule 5.20,

liability for excise tax or penalty due to the Internal Revenue Service nor any
liability to the Pension Benefit Guaranty Corporation. The STOCKHOLDERS further
represent that:

      discontinuance of contributions to any such Qualified Plan intended to
      qualify under Section 401(a) of the Code without notice to and approval by
      the Internal Revenue Service;

            (ii) no such plan listed in Schedule 5.19 subject to the provisions
      of Title IV of ERISA has been terminated;

                                    -22-

            (iii) there have been no "reportable events" (as that phrase is
      defined in Section 4043 of ERISA) with respect to any such plan listed in
      Schedule 5.19;

            (iv) COMPANY (including the COMPANY's Subsidiaries) has not incurred
      liability under Section 4062 of ERISA; and

            (v) No circumstances exist pursuant to which the COMPANY could have
      any direct or indirect liability whatsoever (including, but not limited
      to, any liability to any multiemployer plan or the PBGC under Title IV of
      ERISA or to the Internal Revenue Service for any excise tax or penalty, or
      being subject to any statutory lien to secure payment of any such
      liability) with respect to any plan now or heretofore maintained or
      contributed to by any entity other than the COMPANY that is, or at any
      time was, a member of a "controlled group" (as defined in Section
      412(n)(6)(B) of the Code) that includes the COMPANY. 5.21 CONFORMITY WITH
      LAW; LITIGATION. Except to the extent set forth on Schedule 5.21

or 5.13, the COMPANY is not in violation of any law or regulation or any order

      7.7 NOTIFICATION OF CERTAIN MATTERS. The STOCKHOLDERS and the COMPANY
shall give prompt notice to CSI of (i) the occurrence or non-occurrence of any

respect at or prior to the Closing and (ii) any material failure of CSI or NEWCO
to comply with or satisfy any covenant, condition or agreement to be complied

such party shall have the continuing obligation until 24 hours prior to the

promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of

a Schedule prepared by the COMPANY that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless CSI and
a majority of the Founding Companies other than the COMPANY consent to such
amendment or supplement; and provided further, that no amendment or supplement
to a Schedule prepared by CSI or NEWCO that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless a

determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other

such Other Founding Company, CSI shall give the COMPANY notice promptly after it
has knowledge thereof. If CSI and a majority of the

                                    -42-

Founding Companies consent to such amendment or supplement, which consent shall
have been deemed given by CSI or any Founding Company if no response is received
within 24 hours following receipt of notice of such amendment or supplement (or
sooner if required by the circumstances under which such consent is requested),
but the COMPANY does not give its consent, the COMPANY may terminate this
Agreement pursuant to Section 12.1(iv) hereof. In the event that the COMPANY
seeks to amend or supplement a Schedule pursuant to this Section 7.8, and CSI
and a majority of the Other Founding Companies do not consent to such amendment
or supplement, this Agreement shall be deemed terminated by mutual consent as
set forth in Section 12.1(i) hereof. In the event that CSI or NEWCO seeks to
amend or supplement a Schedule pursuant to this Section 7.8 and a majority of
the Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. No party to this Agreement shall be liable to any other party if
this Agreement shall be terminated pursuant to the provisions of this Section
7.8. No amendment of or supplement to a Schedule shall be made later than 24

warrants, as to such information with respect to the COMPANY and himself or
herself, that the Registration Statement will not include an untrue statement of

statements, all of such financial statements will present fairly the results of
operations of the COMPANY for the periods indicated therein.

If it is determined by the parties to this Agreement that filings under the
Hart-Scott Act are required, then: (i) each of the parties hereto agrees to
cooperate and use its best efforts to comply with the Hart-Scott Act, (ii) such
compliance by the STOCKHOLDERS and the COMPANY shall be deemed a condition

      9.13 CLOSING OF IPO. The closing of the sale of the CSI Stock to the
Underwriters in the IPO shall have occurred simultaneously with the Funding and
Consummation Date hereunder.

      9.14  FIRPTA CERTIFICATE.  Each STOCKHOLDER shall have delivered to CSI a

certificate to the effect that he is not a foreign person pursuant to Section
1.1445-2(b) of the Treasury regulations.

10.   COVENANTS OF CSI AND THE STOCKHOLDERS AFTER CLOSING

      10.1 RELEASE FROM GUARANTEES; REPAYMENT OF CERTAIN OBLIGATIONS. CSI shall
use its best efforts to have the STOCKHOLDERS released from any and all
guarantees on any indebtedness that they personally guaranteed and from any and
all pledges of assets that they pledged to secure such indebtedness for the
benefit of the COMPANY, with all such guarantees on indebtedness being assumed
by CSI. In the event that CSI cannot obtain such releases from the lenders of
any such guaranteed indebtedness on or prior to 120 days subsequent to the
Funding and Consummation Date, CSI shall pay off or otherwise refinance or
retire such indebtedness. From and after the Funding and Consummation Date and
until such time as all of such indebtedness is paid off, refinanced or retired,
CSI shall maintain unencumbered funds in amounts sufficient to provide for such
pay off, refinancing or retirement, provided that CSI may use such funds for
other purposes, in its sole discretion, with the prior written consent of each
STOCKHOLDER who has not as of that time been released from his or her guarantee
as described above and whose indebtedness as described above has not as of that
time been paid off, refinanced or retired.

      10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as contemplated
by this Agreement or the Registration Statement, after the Funding and
Consummation Date, CSI shall not

                                    -51-

and shall not permit any of its subsidiaries to undertake any act that would
jeopardize the tax-free status of the organization, including without
limitation:

            (a) the retirement or reacquisition, directly or indirectly, of all
      or part of the CSI Stock issued in connection with the transactions
      contemplated hereby; or

            (b) the entering into of financial arrangements for the benefit of
      the STOCKHOLDERS.

      10.3  PREPARATION AND FILING OF TAX RETURNS.

            (i) The COMPANY shall, if possible, file or cause to be filed all
      separate Returns of any Acquired Party for all taxable periods that end on
      or before the Funding and Consummation Date. Notwithstanding the
      foregoing, the STOCKHOLDERS shall file or cause to be filed all separate
      federal income Tax Returns (and any State and local Tax Returns filed on
      the basis similar to that of S corporations under federal income Tax
      rules) of any Acquired Party for all taxable periods that end on or before
      the Funding and Consummation Date. Each STOCKHOLDER shall pay or cause to
      be paid all Tax liabilities (in excess of all amounts already paid with
      respect thereto or properly accrued or reserved with respect thereto on
      the COMPANY Financial Statements) shown by such Returns to be due.

            (ii) CSI shall file or cause to be filed all separate Returns of, or
      that include, any Acquired Party for all taxable periods ending after the
      Funding and Consummation Date.

            (iii) Each party hereto shall, and shall cause its subsidiaries and
      affiliates to, provide to each of the other parties hereto such
      cooperation and information as any of them reasonably may request in
      filing any Return, amended Return or claim for refund, determining a
      liability for Taxes or a right to refund of Taxes or in conducting any
      audit or other proceeding in respect of Taxes. Such cooperation and
      information shall include providing copies of all relevant portions of
      relevant Returns, together with relevant accompanying schedules and
      relevant work papers, relevant documents relating to rulings

                                    -52-

      or other determinations by Taxing Authorities and relevant records
      concerning the ownership and Tax basis of property, which such party may
      possess. Each party shall make its employees reasonably available on a
      mutually convenient basis at its cost to provide explanation of any
      documents or information so provided. Subject to the preceding sentence,
      each party required to file Returns pursuant to this Agreement shall bear
      all costs of filing such Returns.

            (iv) Each of the COMPANY, NEWCO, CSI and each STOCKHOLDER shall
      comply with the tax reporting requirements of Section 1.351-3 of the
      Treasury Regulations promulgated under the Code, and treat the transaction
      as a tax-free contribution under Section 351(a) of the Code subject to
      gain, if any, recognized on the receipt of cash or other property under
      Section 351(b) of the Code. 10.4 DIRECTORS. The persons named in the draft
      of the Registration Statement shall be

appointed as directors and elected as officers of CSI, as and to the extent set
forth in the draft of the Registration Statement, promptly following the Funding
and Consummation Date. This provision shall not imply that the STOCKHOLDERS have
any power or duty to elect officers of CSI.

      10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation to provide
replacement plans that have the same terms and provisions as the existing plans,
provided, further, that any new health insurance plan shall provide for coverage
for preexisting conditions. On the Funding and Consummation Date, the employees
of the COMPANY will be the employees of the Surviving Corporation (provided that
this provision is for purposes of clarifying that the Merger, in and of itself,
will not have any impact on the employment status of any employee and provided,
further that this provision shall not in any way limit the management rights of
the Surviving

                                    -53-

Corporation or CSI to assess workforce needs and make appropriate adjustments as
necessary or desirable within their discretion subject to applicable laws and
collective bargaining agreements).

      10.6 DIVIDENDS. If the COMPANY is an S corporation, the COMPANY may pay to
each STOCKHOLDER as a dividend the full amount of his or her retained earnings
as of the Balance Sheet Date, and may also pay to the STOCKHOLDERS as a dividend
the full amount of the COMPANY's earnings taxable to such STOCKHOLDERS for the
period after the Balance Sheet Date to the Funding and Consummation Date. If the
COMPANY is a C corporation, the COMPANY may pay to the STOCKHOLDERS as a
dividend the full amount of the COMPANY's earnings for the period after the
Balance Sheet Date to the Funding and Consummation Date. The COMPANY may borrow
funds to the extent necessary to make the payments contemplated by this Section
10.6 and to the extent necessary to ensure that the COMPANY has cash on hand to
adequately fund operations on the Funding and Consummation Date.

11.   INDEMNIFICATION

      The STOCKHOLDERS, CSI and NEWCO each make the following covenants that are
applicable to them, respectively:

      11.1  GENERAL INDEMNIFICATION BY THE STOCKHOLDERS.  The STOCKHOLDERS

covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless CSI, NEWCO, the COMPANY and the Surviving Corporation
at all times, from and after the date

                                    -54-

of this Agreement until the Expiration Date, from and against all claims,
damages, actions, suits, proceedings, demands, assessments, adjustments, costs
and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by CSI, NEWCO, the
COMPANY or the Surviving Corporation as a result of or arising from (i) any
breach of the representations and warranties of the STOCKHOLDERS or the COMPANY
set forth herein or on the schedules or certificates delivered in connection
herewith, (ii) any breach of any agreement on the part of the STOCKHOLDERS or
the COMPANY under this Agreement, or (iii) any liability under the 1933 Act, the
1934 Act or other Federal or state law or regulation, at common law or
otherwise, arising out of or based upon any untrue statement or alleged untrue
statement of a material fact relating to the COMPANY or the STOCKHOLDERS, and
provided to CSI or its counsel by the COMPANY or the STOCKHOLDERS (but in the
case of the STOCKHOLDERS, only if such statement was provided in writing)
contained in the Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or arising out of or
based upon any omission or alleged omission to state therein a material fact
relating to the COMPANY or the STOCKHOLDERS required to be stated therein or
necessary to make the statements therein not misleading, provided, however, that
such indemnity shall not inure to the benefit of CSI, NEWCO, the COMPANY or the
Surviving Corporation to the extent that such untrue statement (or alleged
untrue statement) was made in, or omission (or alleged omission) occurred in,
any preliminary prospectus and the STOCKHOLDERS provided, in writing, corrected
information to CSI counsel and to CSI for inclusion in the final prospectus, and
such information was not so included or properly delivered, and provided
further, that no STOCKHOLDER shall be liable for any indemnification obligation
pursuant to this Section 11.1 to the extent attributable to a breach of any
representation, warranty or agreement made herein individually by any other
STOCKHOLDER.

      11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDERS at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits,

                                    -55-

proceedings, demands, assessments, adjustments, costs and expenses (including
specifically, but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by the STOCKHOLDERS as a result of or arising from (i)
any breach by CSI or NEWCO of their representations and warranties set forth
herein or on the schedules or certificates attached hereto, (ii) any
nonfulfillment of any agreement on the part of CSI or NEWCO under this
Agreement, (iii) any liabilities which the STOCKHOLDERS may incur due to CSI's
or NEWCO's failure to be responsible for the liabilities and obligations of the
COMPANY as provided in Section 1 hereof (except to the extent that CSI or NEWCO
has claims against the STOCKHOLDERS by reason of such liabilities); or (iv) any
liability under the 1933 Act, the 1934 Act or other Federal or state law or
regulation, at common law or otherwise, arising out of or based upon any untrue
statement or alleged untrue statement of a material fact relating to CSI, NEWCO
or any of the Other Founding Companies contained in any preliminary prospectus,
the Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to CSI or
NEWCO or any of the Other Founding Companies required to be stated therein or
necessary to make the statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has knowledge of any claim by a
person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying

                                    -56-

Party shall not settle any criminal proceeding without the written consent of
the Indemnified Party. If the Indemnifying Party undertakes to defend or settle,
it shall promptly notify the Indemnified Party of its intention to do so, and
the Indemnified Party shall cooperate with the Indemnifying Party and its
counsel in the defense thereof and in any settlement thereof. Such cooperation
shall include, but shall not be limited to, furnishing the Indemnifying Party
with any books, records or information reasonably requested by the Indemnifying
Party that are in the Indemnified Party's possession or control. All Indemnified
Parties shall use the same counsel, which shall be the counsel selected by
Indemnifying Party, provided that if counsel to the Indemnifying Party shall
have a conflict of interest that prevents counsel for the Indemnifying Party
from representing Indemnified Party, Indemnified Party shall have the right to
participate in such matter through counsel of its own choosing and Indemnifying
Party will reimburse the Indemnified Party for the reasonable expenses of its
counsel. After the Indemnifying Party has notified the Indemnified Party of its
intention to undertake to defend or settle any such asserted liability, and for
so long as the Indemnifying Party diligently pursues such defense, the
Indemnifying Party shall not be liable for any additional legal expenses
incurred by the Indemnified Party in connection with any defense or settlement
of such asserted liability, except (i) as set forth in the preceding sentence
and (ii) to the extent such participation is requested by the Indemnifying
Party, in which event the Indemnified Party shall be reimbursed by the
Indemnifying Party for reasonable additional legal expenses and out-of-pocket
expenses. If the Indemnifying Party desires to accept a final and complete
settlement of any such Third Person claim and the Indemnified Party refuses to
consent to such settlement, then the Indemnifying Party's liability under this
Section with respect to such Third Person claim shall be limited to the amount
so offered in settlement by said Third Person. Upon agreement as to such
settlement between said Third Person and the Indemnifying Party, the
Indemnifying Party shall, in exchange for a complete release from the
Indemnified Party, promptly pay to the Indemnified Party the amount agreed to in
such settlement and the Indemnified Party shall, from that moment on, bear full
responsibility for any additional costs of defense which it subsequently incurs
with respect to

                                    -57-

such claim and all additional costs of settlement or judgment. If the
Indemnifying Party does not undertake to defend such matter to which the
Indemnified Party is entitled to indemnification hereunder, or fails diligently
to pursue such defense, the Indemnified Party may undertake such defense through
counsel of its choice, at the cost and expense of the Indemnifying Party, and
the Indemnified Party may settle such matter, and the Indemnifying Party shall
reimburse the Indemnified Party for the amount paid in such settlement and any
other liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the Indemnified Party otherwise agrees in writing. The parties
hereto will make appropriate adjustments for insurance proceeds in determining
the amount of any indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section 11
shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

      11.5 LIMITATIONS ON INDEMNIFICATION. CSI, NEWCO, the Surviving Corporation
and the other persons or entities indemnified pursuant to Section 11.1 or 11.2
shall not assert any claim for indemnification hereunder against the
STOCKHOLDERS until such time as, and solely to the extent that, the aggregate of
all claims which such persons may have against such the STOCKHOLDERS shall
exceed the greater of (a) 1.0% of the sum of the cash paid to STOCKHOLDERS plus
the value of the CSI Stock delivered to STOCKHOLDERS (calculated as provided in
this Section 11.5) or (b) $50,000 (the "Indemnification Threshold").
STOCKHOLDERS shall not assert any claim for indemnification hereunder against
CSI or NEWCO until such time as, and solely to the extent that,

                                    -58-

the aggregate of all claims which STOCKHOLDERS may have against CSI or NEWCO
shall exceed $50,000.

      No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

      Notwithstanding any other term of this Agreement, no STOCKHOLDER shall be
liable under this Section 11 for an amount which exceeds the amount of proceeds
received by such STOCKHOLDER in connection with the Merger. For purposes of
calculating the value of the CSI Stock received by a STOCKHOLDER, CSI Stock
shall be valued at its initial public offering price as set forth in the
Registration Statement. It is hereby understood and agreed that a STOCKHOLDER
may satisfy an indemnification obligation through payment of a combination of
stock and cash in proportion equal to the proportion of stock and cash received
by such STOCKHOLDER in connection with the Merger, valued as described
immediately above.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION.This Agreement may be terminated at any time prior to the
Funding and Consummation Date solely:

      (i)   by mutual consent of the boards of directors of CSI and the COMPANY;

      (ii) by the STOCKHOLDERS or the COMPANY (acting through its board of
directors), on the one hand, or by CSI (acting through its board of directors),
on the other hand, if the transactions contemplated by this Agreement to take
place at the Closing shall not have been consummated by September 30, 1997,
unless the failure of such transactions to be consummated is due to the willful
failure of the party seeking to terminate this Agreement to perform any of its
obligations under this Agreement to the extent required to be performed by it
prior to or on the Funding and Consummation Date;

                                    -59-

      (iii) by the STOCKHOLDERS or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due and timely performance of any of the covenants or
agreements contained herein, and the curing of such default shall not have been
made on or before the Funding and Consummation Date or by the STOCKHOLDERS or
the COMPANY, if the conditions set forth in Section 8 hereof have not been
satisfied or waived as of the Closing Date or the Funding and Consummation Date,
as applicable, or by CSI, if the conditions set forth in Section 9 hereof have
not been satisfied or waived as of the Closing Date or the Funding and
Consummation Date, as applicable;

      (iv)  pursuant to Section 7.8 hereof; or
      (v)   pursuant to Section 4 hereof.

      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. The STOCKHOLDERS will not, for a period of
five (5) years following the Funding and Consummation Date, for any reason
whatsoever, directly or indirectly, for themselves or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

      (i) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial capacity, whether as an employee, independent
contractor, consultant or advisor, or as a sales representative, in any heating,
ventilating or air conditioning services business in direct competition with CSI
or any of the subsidiaries thereof, within 100 miles of where the COMPANY

                                    -60-

or any of its subsidiaries conducted business prior to the effectiveness of the
Merger (the "Territory");

      (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the subsidiaries
thereof), provided that each STOCKHOLDER shall be permitted to call upon and
hire any member of his or her immediate family;

      (iii) call upon any person or entity which is, at that time, or which has
been, within one (1) year prior to the Funding and Consummation Date, a customer
of CSI (including the subsidiaries thereof), of the COMPANY or of any of the
Other Founding Companies within the Territory for the purpose of soliciting or
selling products or services in direct competition with CSI within the
Territory;

      (iv) call upon any prospective acquisition candidate, on any STOCKHOLDER's
own behalf or on behalf of any competitor in the heating, ventilation or air
conditioning services business, which candidate, to the actual knowledge of such
STOCKHOLDER after due inquiry, was called upon by CSI (including the
subsidiaries thereof) or for which, to the actual knowledge of such STOCKHOLDER
after due inquiry, CSI (or any subsidiary thereof) made an acquisition analysis,
for the purpose of acquiring such entity; or

      (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

                                    -61-

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to CSI for which it would
have no other adequate remedy, each STOCKHOLDER agrees that the foregoing
covenant may be enforced by CSI in the event of breach by such STOCKHOLDER, by
injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDERS in light of the activities and business of CSI (including the
subsidiaries thereof) on the date of the execution of this Agreement and the
current plans of CSI.

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of each STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which such
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

                                    -62-

      13.6 MATERIALITY. The COMPANY and the STOCKHOLDERS hereby agree that this
covenant is a material and substantial part of this transaction.

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1  STOCKHOLDERS. The STOCKHOLDERS recognize and acknowledge that they

had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. The STOCKHOLDERS agree that they
will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except (a) to authorized representatives of CSI, (b) following the Closing, such
information may be disclosed by the STOCKHOLDERS as is required in the course of
performing their duties for CSI or the Surviving Corporation and (c) to counsel
and other advisers, provided that such advisers (other than counsel) agree to
the confidentiality provisions of this Section 14.1, unless (i) such information
becomes known to the public generally through no fault of the STOCKHOLDERS, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), the STOCKHOLDERS shall, if possible, give prior written notice
thereof to CSI and provide CSI with the opportunity to contest such disclosure,
or (iii) the disclosing party reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party. In the event of a breach or threatened breach by any of the STOCKHOLDERS
of the provisions of this Section, CSI shall be entitled to an injunction
restraining such STOCKHOLDERS from disclosing, in whole or in part, such
confidential information. Nothing herein shall be construed as prohibiting CSI
from pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. In the event the transactions contemplated by
this Agreement are not consummated,

                                    -63-

STOCKHOLDERS shall have none of the above-mentioned restrictions on their
ability to disseminate confidential information with respect to the COMPANY.

      14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they had
in the past and currently have access to certain confidential information of the
COMPANY, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, (c) to the Other Founding Companies and their representatives pursuant to
Section 7.1(a), unless (i) such information becomes known to the public
generally through no fault of CSI or NEWCO, (ii) disclosure is required by law
or the order of any governmental authority under color of law, provided, that
prior to disclosing any information pursuant to this clause (ii), CSI and NEWCO
shall, if possible, give prior written notice thereof to the COMPANY and the
STOCKHOLDERS and provide the COMPANY and the STOCKHOLDERS with the opportunity
to contest such disclosure, or (iii) the disclosing party reasonably believes
that such disclosure is required in connection with the defense of a lawsuit
against the disclosing party, and (d) to the public to the extent necessary or
advisable in connection with the filing of the Registration Statement and the
IPO and the securities laws applicable thereto and to the operation of CSI as a
publicly held entity after the IPO. In the event of a breach or threatened
breach by CSI or NEWCO of the provisions of this Section, the COMPANY and the
STOCKHOLDERS shall be entitled to an injunction restraining CSI and NEWCO from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting the COMPANY and the STOCKHOLDERS from pursuing
any other available remedy for such breach or threatened breach, including the
recovery of damages.

                                    -64-

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Funding and Consummation Date.

15.   TRANSFER RESTRICTIONS

      15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDERS or family members, the trustees
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the STOCKHOLDERS shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of CSI Stock as described in Section 3.1 received by the STOCKHOLDERS in
the Merger. The certificates evidencing the CSI Stock delivered to the
STOCKHOLDERS pursuant to Section 3 of this Agreement will bear a legend

as CSI may deem necessary or appropriate: THE SHARES REPRESENTED BY THIS
CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED,
PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL
NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE,
TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION
PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE WRITTEN REQUEST OF THE
HOLDER OF THIS

                                    -65-

CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY STOP
ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED ABOVE.

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The STOCKHOLDERS acknowledge that the shares of
CSI Stock to be delivered to the STOCKHOLDERS pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and may not be resold without compliance with the Act. The CSI Stock
to be acquired by such STOCKHOLDERS pursuant to this Agreement is being acquired
solely for their own respective accounts, for investment purposes only, and with
no present intention of distributing, selling or otherwise disposing of it in
connection with a distribution. The STOCKHOLDERS covenant, warrant and represent
that none of the shares of CSI Stock issued to such STOCKHOLDERS will be
offered, sold, assigned, pledged, hypothecated, transferred or otherwise
disposed of except after full compliance with all of the applicable provisions
of the Act and the rules and regulations of the SEC. All the CSI Stock shall
bear the following legend in addition to the legend required under Section 15 of
this Agreement: THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED
IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

      16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDERS are able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and have
such knowledge and experience in financial and business matters that they are
capable of evaluating the merits and risks of the proposed

                                    -66-

investment in the CSI Stock. The STOCKHOLDERS party hereto have had an adequate
opportunity to ask questions and receive answers from the officers of CSI
concerning any and all matters relating to the transactions described herein
including, without limitation, the background and experience of the current and
proposed officers and directors of CSI, the plans for the operations of the
business of CSI, the business, operations and financial condition of the
Founding Companies other than the COMPANY, and any plans for additional
acquisitions and the like. The STOCKHOLDERS have asked any and all questions in
the nature described in the preceding sentence and all questions have been
answered to their satisfaction.

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
each of the STOCKHOLDERS prompt written notice of its intent to do so. Upon the
written request of any of the STOCKHOLDERS given within 30 days after receipt of
such notice, CSI shall cause to be included in such registration all of the CSI
Stock issued to the STOCKHOLDERS pursuant to this Agreement (including any stock
issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) which any such STOCKHOLDER requests, provided that CSI shall
have the right to reduce the number of shares included in such registration to
the extent that inclusion of such shares could, in the opinion of tax counsel to
CSI or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Registration Statement as a tax-free
organization. In addition, if CSI is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1

                                    -67-

that the number of shares to be sold by persons other than CSI is greater than
the number of such shares which can be offered without adversely affecting the
offering, CSI may reduce pro rata the number of shares offered for the accounts
of such persons (based upon the number of shares held by such person) to a
number deemed satisfactory by such managing underwriter, provided, that, for
each such offering made by CSI after the IPO, such reduction shall be made first
by reducing the number of shares to be sold by persons other than CSI, the
STOCKHOLDERS and the stockholders of the Other Founding Companies (collectively,
the STOCKHOLDERS and the stockholders of the other Founding Companies being
referred to herein as the "Founding Stockholders"), and thereafter, if a further
reduction is required, by reducing the number of shares to be sold by the
Founding Stockholders.

      17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year after
the Closing and prior to the date three years after the Closing, the holders of
a majority of the shares of CSI Stock issued to the Founding Stockholders
pursuant to this Agreement and the Other Agreements which have not been
previously registered or sold and which are not entitled to be sold under Rule
144(k) (or any similar or successor provision) promulgated under the 1933 Act
may request in writing that CSI file a registration statement under the 1933 Act
covering the registration of the shares of CSI Stock issued to the STOCKHOLDERS
pursuant to this Agreement and the Other Agreements (including any stock issued
as (or issuable upon the conversion or exchange of any convertible security,
warrant, right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) then held by such Founding Stockholders (a "Demand Registration"). Within
ten (10) days of the receipt of such request, CSI shall give written notice of
such request to all other Founding Stockholders and shall, as soon as
practicable but in no event later than 45 days after notice from any
STOCKHOLDER, file and use its best efforts to cause to become effective a
registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will

                                    -68-

keep such Demand Registration current and effective for not less than 90 days
(or such shorter period as is required to sell all of the shares registered
thereby).

      Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the date on which CSI
would otherwise be required to make such filing pursuant to the foregoing
paragraph.

      If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective date of such registration unless CSI is no longer proceeding
diligently to effect such registration; provided that CSI shall provide the
Founding Stockholders the right to participate in such public offering pursuant
to, and subject to, Section 17.1 hereof.

      17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with the
registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

                                    -69-

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Sections 17.1 and 17.2 covering an underwritten registered offering, CSI and
each participating holder agree to enter into a written agreement with the
managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
managing underwriters and companies of CSI's size and investment stature,
including indemnification.

      17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by any STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to such STOCKHOLDER.

      17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

            (i) make and keep public information regarding CSI available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of CSI under the 1933 Act and the 1934 Act at any time
      after it has become subject to such reporting requirements; and

            (iii) so long as a STOCKHOLDER owns any restricted CSI Common Stock,
      furnish to each STOCKHOLDER forthwith upon written request a written
      statement by CSI as to its compliance with the reporting requirements of
      Rule 144 (at any time from and after 90 days following the effective date
      of the Registration Statement, and of the 1933 Act and the 1934 Act (at
      any time after it has become subject to such reporting requirements), a
      copy of the most recent annual or quarterly report of CSI, and such other
      reports and documents so filed as a STOCKHOLDER may reasonably request in
      availing itself of any rule or

                                    -70-

      regulation of the SEC allowing a STOCKHOLDER to sell any such shares
      without registration.

18.   GENERAL

strategic alliances and options to purchase land), other than agreements listed
on Schedule 5.10, 5.14 or 5.16, (a) in existence as of the Balance Sheet Date
and (b) entered into since the Balance Sheet Date, and in each case has

      5.16 REAL PROPERTY. Schedule 5.16 includes a list of all real property
owned or leased by the COMPANY at the date hereof, and all other real property,
if any, used by the COMPANY in the conduct of its business. Any such real

received for the past three (3) policy years and

                                    -20-

(iii) true, complete and correct copies of all insurance policies currently in
effect. Such insurance policies evidence all of the insurance that the COMPANY
is required to carry pursuant to all of its contracts and other agreements and
pursuant to all applicable laws. All of such insurance policies are currently in
full force and effect and shall remain in full force and effect through the
Funding and Consummation Date. Since January 1, 1994, no insurance carried by
the COMPANY has been canceled by the insurer and the COMPANY has not been denied
coverage.

      5.18 COMPENSATION; EMPLOYMENT AGREEMENTS; ORGANIZED LABOR MATTERS. The
COMPANY has delivered to CSI an accurate list (which is set forth on Schedule
5.18) showing all officers, directors and key employees of the COMPANY, listing
all employment agreements with such officers, directors and key employees and

Balance Sheet Date and (ii) the date hereof. The COMPANY has provided to CSI
true, complete and correct copies of any employment agreements for persons
listed on Schedule 5.18. Since the Balance Sheet Date, there have been no
increases in the compensation payable or any special bonuses to any officer,
director, key employee or other employee, except ordinary salary increases
implemented on a basis consistent with past practices.

            Except as set forth on Schedule 5.18, (i) the COMPANY is not bound
by or subject to (and none of its respective assets or properties is bound by or
subject to) any arrangement with any labor union, (ii) no employees of the
COMPANY are represented by any labor union or covered by any collective
bargaining agreement, (iii) to the knowledge of the COMPANY, no campaign to
establish such representation is in progress and (iv) there is no pending or, to
the best of the COMPANY's knowledge, threatened labor dispute involving the
COMPANY and any group of its employees nor has the COMPANY experienced any labor
interruptions over the past three years.

The COMPANY believes its relationship with employees to be good.

      5.19 EMPLOYEE PLANS. The STOCKHOLDER have delivered to CSI an accurate
schedule (Schedule 5.19) showing all employee benefit plans of COMPANY
(including COMPANY's

                                    -21-

Subsidiaries), including all employment agreements and other agreements or
arrangements containing "golden parachute" or other similar provisions, and
deferred compensation agreements, together with true, complete and correct
copies of such plans, agreements and any trusts related thereto, and
classifications of employees covered thereby as of the Balance Sheet Date.
Except for the employee benefit plans, if any, described on Schedule 5.19,
COMPANY (including the COMPANY's Subsidiaries) does not sponsor, maintain or
contribute to any plan program, fund or arrangement that constitutes an
"employee pension benefit plan," nor has COMPANY or any Subsidiary any
obligation to contribute to or accrue or pay any benefits under any deferred
compensation or retirement funding arrangement on behalf of any employee or
employees (such as, for example, and without limitation, any individual
retirement account or annuity, any "excess benefit plan" (within the meaning of
Section 3(36) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) or any non-qualified deferred compensation arrangement). For the
purposes of this Agreement, the term "employee pension benefit plan" shall have
the same meaning as is given that term in Section 3(2) of ERISA. Neither COMPANY
nor any Subsidiary has sponsored, maintained or contributed to any employee
pension benefit plan other than the plans set forth on Schedule 5.19, nor is
COMPANY or any Subsidiary required to contribute to any retirement plan pursuant
to the provisions of any collective bargaining agreement establishing the terms
and conditions or employment of any of COMPANY's or any Subsidiary's employees.

      Neither the COMPANY nor any Subsidiary is now, or can as a result of its
past activities become, liable to the Pension Benefit Guaranty Corporation or to
any multiemployer employee pension benefit plan under the provisions of Title IV
of ERISA.

      All employee benefit plans listed on Schedule 5.19 and the administration
thereof are in substantial compliance with their terms and all applicable
provisions of ERISA and the regulations issued thereunder, as well as with all
other applicable federal, state and local statutes, ordinances and regulations.

                                    -22-

      All accrued contribution obligations of COMPANY or any Subsidiary with
respect to any plan listed on Schedule 5.19 have either been fulfilled in their
entirety or are fully reflected on the balance sheet of the COMPANY as of the
Balance Sheet Date.

      5.20 COMPLIANCE WITH ERISA. All such plans listed on Schedule 5.19 that
are intended to qualify (the "Qualified Plans") under Section 401(a) of the Code
are, and have been so qualified and have been determined by the Internal Revenue
Service to be so qualified, and copies of such determination letters are
included as part of Schedule 5.19 hereof. Except as disclosed on Schedule 5.20,
all reports and other documents required to be filed with any governmental
agency or distributed to plan participants or beneficiaries (including, but not
limited to, actuarial reports, audits or tax returns) have been timely filed or
distributed, and copies thereof are included as part of Schedule 5.19 hereof.
Neither STOCKHOLDER, any such plan listed in Schedule 5.19, nor COMPANY
(including the COMPANY's Subsidiaries) has engaged in any transaction prohibited
under the provisions of Section 4975 of the Code or Section 406 of ERISA. No
such Plan listed in Schedule 5.19 has incurred an accumulated funding
deficiency, as defined in Section 412(a) of the Code and Section 302(1) of
ERISA; and COMPANY (including the COMPANY's Subsidiaries) has not incurred any
liability for excise tax or penalty due to the Internal Revenue Service nor any
liability to the Pension Benefit Guaranty Corporation. The STOCKHOLDER further
represent that:

            (i) there have been no terminations, partial terminations or
      discontinuance of contributions to any such Qualified Plan intended to
      qualify under Section 401(a) of the Code without notice to and approval by
      the Internal Revenue Service;

            (ii) no such plan listed in Schedule 5.19 subject to the provisions
      of Title IV of ERISA has been terminated;

            (iii) there have been no "reportable events" (as that phrase is
      defined in Section 4043 of ERISA) with respect to any such plan listed in
      Schedule 5.19;

            (iv) COMPANY (including the COMPANY's Subsidiaries) has not incurred
      liability under Section 4062 of ERISA; and

                                    -23-

            (v) No circumstances exist pursuant to which the COMPANY could have
      any direct or indirect liability whatsoever (including, but not limited
      to, any liability to any multiemployer plan or the PBGC under Title IV of
      ERISA or to the Internal Revenue Service for any excise tax or penalty, or
      being subject to any statutory lien to secure payment of any such
      liability) with respect to any plan now or heretofore maintained or
      contributed to by any entity other than the COMPANY that is, or at any
      time was, a member of a "controlled group" (as defined in Section
      412(n)(6)(B) of the Code) that includes the COMPANY. 

      5.21 CONFORMITY WITH LAW; LITIGATION. Except to the extent set forth on
Schedule 5.21 or 5.13, the COMPANY is not in violation of any law or regulation

jurisdiction over any of them which would have a Material Adverse Effect; and
except to the extent set forth on Schedule 5.10 or 5.13, there are no material
claims, actions, suits or proceedings, pending or, to the knowledge of the
COMPANY, threatened against or affecting, the COMPANY, at law or in equity, or
before or by any Federal, state, municipal or other governmental department,
commission, board, bureau, agency or instrumentality having jurisdiction over
any of them and no notice of any claim, action, suit or proceeding, whether
pending or threatened, has been received. The COMPANY has conducted and is
conducting its business in substantial compliance with the requirements,
standards, criteria and conditions set forth in applicable Federal, state and
local statutes, ordinances, permits, licenses, orders, approvals, variances,
rules and regulations, including all such permits, licenses, orders and other
governmental approvals set forth on Schedules 5.12 and 5.13, and is not in
violation of any of the foregoing which would have a Material Adverse Effect.

      5.22 TAXES. COMPANY (including the COMPANY's Subsidiaries) has timely
filed all requisite federal, state and other tax returns or extension requests
for all fiscal periods ended on or before the Balance Sheet Date; and except as
set forth on Schedule 5.22, there are no examinations in progress or claims
against any of them for federal, state and other taxes (including penalties and

                                    -24-

interest) for any period or periods prior to and including the Balance Sheet
Date and no notice of any claim for taxes, whether pending or threatened, has
been received. All tax, including interest and penalties (whether or not shown
on any tax return) owed by the COMPANY, any of the COMPANY's Subsidiaries, any
member of an affiliated or consolidated group which includes or included the
COMPANY or any of the COMPANY's Subsidiaries, or with respect to any payment
made or deemed made by the COMPANY or any of the COMPANY's Subsidiaries herein
been paid. The amounts shown as accruals for taxes on the COMPANY Financial
Statements are sufficient for the payment of all taxes of the kinds indicated
(including penalties and interest) for all fiscal periods ended on or before
that date. Copies of (i) any tax examinations, (ii) extensions of statutory
limitations and (iii) the federal and local income tax returns and franchise tax
returns of COMPANY (including the COMPANY Subsidiaries) for their last three (3)
fiscal years, or such shorter period of time as any of them shall have existed,
are attached hereto as Schedule 5.22. The STOCKHOLDER made valid elections under
the provisions of Subchapter S of the Code with respect to each Company and the
COMPANY has not, within the past five years, been taxed under the provisions of
Subchapter C of the Code. The COMPANY has a taxable year ended December 31 and

Section 444 of the Code. The COMPANY's methods of accounting have not changed in
the past five years. The COMPANY is not an investment company as defined in
Section 351(e)(1) of the Code.

      5.23 NO VIOLATIONS. The COMPANY is not in violation of any Charter

party thereto, is in material default under any lease, instrument, agreement,
license, or permit set forth on Schedule 5.12, 5.13, 5.14, 5.15 or 5.16, or any

publication by the COMPANY, CSI or NEWCO of the name of any other party to such
Material Document, and none of the Material Documents prohibits or restricts the

truth and accuracy of any and all warranties and representations of the COMPANY,
or on behalf of the COMPANY and of STOCKHOLDER at the date of this Agreement and

at all; (ii) that neither CSI or any of its officers, directors, agents or

                                    -42-

hereafter arising or discovered which, if existing or known at the date of this
Agreement, would have been required to be set forth or described in the
Schedules, provided however, that supplements and amendments to Schedules 5.10,
5.11, 5.14 and 5.15 shall only have to be delivered at the Closing Date, unless
such Schedule is to be amended to reflect an event occurring other than in the
ordinary course of business. Notwithstanding the foregoing sentence, no
amendment or supplement to a Schedule prepared by either COMPANY that
constitutes or reflects an event or occurrence that would have a Material
Adverse Effect may be made unless CSI and a majority of the Founding Companies
other than the COMPANIES consent to such amendment or supplement; and provided
further, that no amendment or supplement to a Schedule prepared by CSI or any
NEWCO that constitutes or reflects an event or occurrence that would have a

set forth in Sections 8.1 and 9.1 have been fulfilled, the Schedules hereto
shall be deemed to be the Schedules as amended or supplemented pursuant to this
Section 7.8. In the event that one of the Other Founding Companies seeks to

occurrence that would have a Material Adverse Effect on such Other Founding
Company, CSI shall give the COMPANY notice promptly after it has knowledge
thereof. If CSI and a majority of the Founding Companies consent to such
amendment or supplement, which consent shall have been deemed given by CSI or
any Founding Company if no response is received within 24 hours following
receipt of notice of such amendment or supplement (or sooner if required by the
circumstances under which such consent is requested), but the COMPANY does not
give its consent (provided that consent shall be deemed given if any COMPANY
consents), the COMPANY may terminate this Agreement pursuant to Section 12.1(iv)
hereof. In the event that any COMPANY seeks to amend or supplement a Schedule
pursuant to this Section 7.8, and CSI and a majority of the Other Founding
Companies do not consent to such amendment or supplement, this Agreement shall

                                    -43-

be deemed terminated by mutual consent as set forth in Section 12.1(i) hereof.
In the event that CSI or any NEWCO seeks to amend or supplement a Schedule
pursuant to this Section 7.8 and a majority of the Founding Companies do not
consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the
anticipated effectiveness of the Registration Statement.

represents and warrants as to such information with respect to itself, and each
Stockholder represents and warrants, as to such information with respect to such
COMPANY and himself or herself, that the Registration Statement will not include
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading.

Funding and Consummation Date, and CSI shall have had sufficient time to review

following the Balance Sheet Date, and the unaudited consolidated statement of
income, cash flows and retained earnings of such COMPANY for all fiscal quarters
ended after the Balance Sheet Date, disclosing no material adverse change in the
financial condition of such COMPANY or the results of its operations from the

such financial statements will present fairly the results of operations of each
COMPANY for the periods indicated therein.

as set forth in the Registration Statement filed with the SEC except for such
changes in authorized capital stock as are made to respond to comments made by
the SEC or requirements of any exchange or automated trading system for which

Agreement that filings under the Hart-Scott Act are required, then: (i) each of

use its best efforts to have the STOCKHOLDER released from any and all
guarantees on any indebtedness that he personally guaranteed and from any and
all pledges of assets that he pledged to secure such indebtedness for the
benefit of the COMPANY, with all such guarantees on indebtedness being assumed
by CSI. In the event that CSI cannot obtain such releases from the lenders of
any such guaranteed indebtedness on or prior to 120 days subsequent to the
Funding and Consummation Date, CSI shall pay off or otherwise refinance or
retire such indebtedness. From and after the Funding and Consummation Date and
until such time as all of such indebtedness is paid off, refinanced or retired,
CSI shall maintain unencumbered funds in amounts sufficient to provide for such
pay off, refinancing or retirement, provided that CSI may use such funds for
other purposes, in its sole discretion, with the prior written consent of each
STOCKHOLDER who has not as of that time been released from his or her guarantee
as described above and whose indebtedness as described above has not as of that
time been paid off, refinanced or retired.

      10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as contemplated
by this Agreement or the Registration Statement, after the Funding and
Consummation Date, CSI shall not and shall not permit any of its subsidiaries to
undertake any act that would jeopardize the tax-free status of the organization,
including without limitation:

                                    -52-

            (a) the retirement or reacquisition, directly or indirectly, of all
      or part of the CSI Stock issued in connection with the transactions
      contemplated hereby; or

            (b) the entering into of financial arrangements for the benefit of
      the STOCKHOLDER.

      10.3  PREPARATION AND FILING OF TAX RETURNS.

            (i) The COMPANY shall, if possible, file or cause to be filed all
      separate Returns of any Acquired Party for all taxable periods that end on
      or before the Funding and Consummation Date. Notwithstanding the
      foregoing, the STOCKHOLDER shall file or cause to be filed all separate
      federal income Tax Returns (and any State and local Tax Returns filed on
      the basis similar to that of S corporations under federal income Tax
      rules) of any Acquired Party for all taxable periods that end on or before
      the Funding and Consummation Date. The STOCKHOLDER shall pay or cause to
      be paid all Tax liabilities (in excess of all amounts already paid with
      respect thereto or properly accrued or reserved with respect thereto on
      the COMPANY Financial Statements) shown by such Returns to be due.

            (ii) CSI shall file or cause to be filed all separate Returns of, or
      that include, any Acquired Party for all taxable periods ending after the
      Funding and Consummation Date.

            (iii) Each party hereto shall, and shall cause its subsidiaries and
      affiliates to, provide to each of the other parties hereto such
      cooperation and information as any of them reasonably may request in
      filing any Return, amended Return or claim for refund, determining a
      liability for Taxes or a right to refund of Taxes or in conducting any
      audit or other proceeding in respect of Taxes. Such cooperation and
      information shall include providing copies of all relevant portions of
      relevant Returns, together with relevant accompanying schedules and
      relevant work papers, relevant documents relating to rulings or other
      determinations by Taxing Authorities and relevant records concerning the
      ownership and Tax basis of property, which such party may possess. Each
      party shall make its

                                    -53-

      employees reasonably available on a mutually convenient basis at its cost
      to provide explanation of any documents or information so provided.
      Subject to the preceding sentence, each party required to file Returns
      pursuant to this Agreement shall bear all costs of filing such Returns.

            (iv) Each of the COMPANY, NEWCO, CSI and the STOCKHOLDER shall
      comply with the tax reporting requirements of Section 1.351-3 of the
      Treasury Regulations promulgated under the Code, and treat the transaction
      as a tax-free contribution under Section 351(a) of the Code subject to
      gain, if any, recognized on the receipt of cash or other property under
      Section 351(b) of the Code. 10.4 DIRECTORS. The persons named in the draft
      of the Registration Statement shall be appointed as directors and elected
      as officers of CSI, as and to the extent set forth in the draft of the
      Registration Statement, promptly following the Funding and Consummation
      Date. This provision shall not imply that the STOCKHOLDERS have any power
      or duty to elect officers of CSI.

      10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation to provide
replacement plans that have the same terms and provisions as the existing plans,
provided, further, that any new health insurance plan shall provide for coverage
for preexisting conditions. On the Funding and Consummation Date, the employees
of each COMPANY will be the employees of the respective Surviving Corporation
(provided that this provision is for purposes of clarifying that the Merger, in
and of itself, will not have any impact on the employment status of any employee
and provided, further that this provision shall not in any way limit the
management rights of such Surviving Corporation or CSI to assess workforce needs
and make appropriate adjustments as necessary or desirable within their
discretion subject to applicable laws and collective bargaining agreements).

                                    -54-

      10.6 DIVIDENDS. The COMPANY may pay to the STOCKHOLDER as a dividend the
full amount of his "accumulated adjustments account" (as defined in Section
1368(e) of the Code) as of the Balance Sheet Date, and may also pay to the
STOCKHOLDER as a dividend the full amount of the COMPANY's earnings taxable to
such STOCKHOLDER for the period after the Balance Sheet Date to the Funding and
Consummation Date. The COMPANY may pay to the STOCKHOLDERS as a dividend the
full amount of the COMPANY's retained earnings as of the Balance Sheet Date. The
COMPANY may borrow funds to the extent necessary to make the payments
contemplated by this Section 10.6 and to the extent necessary to ensure that the
COMPANY has cash on hand to adequately fund operations on the Funding and
Consummation Date.

11.   INDEMNIFICATION

      The STOCKHOLDER, CSI and NEWCO each make the following covenants that are
applicable to them, respectively:

      11.1  GENERAL INDEMNIFICATION BY THE STOCKHOLDER.  The STOCKHOLDER
covenants and agrees that he will indemnify, defend, protect and hold harmless
CSI, NEWCO, the COMPANY and the Surviving Corporation at all times, from and
after the date of this Agreement until the Expiration Date, from and against all
claims, damages, actions, suits, proceedings, demands, assessments, adjustments,
costs and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by CSI, NEWCO, the
COMPANY or the Surviving Corporation as a result of or arising from (i) any
breach of the representations and warranties of the STOCKHOLDER or either
COMPANY set forth herein or on the schedules or certificates delivered in
connection herewith, (ii) any breach of any agreement on the part of the
STOCKHOLDER or either COMPANY under this Agreement, or (iii) any liability under
the 1933 Act, the 1934 Act or other Federal or state law or regulation, at
common law or otherwise, arising

                                    -55-

out of or based upon any untrue statement or alleged untrue statement of a
material fact relating to either COMPANY or the STOCKHOLDER, and provided to CSI
or its counsel by either COMPANY or the STOCKHOLDER (but in the case of the
STOCKHOLDER, only if such statement was provided in writing) contained in the
Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to either
COMPANY or the STOCKHOLDER required to be stated therein or necessary to make
the statements therein not misleading, provided, however, that such indemnity
shall not inure to the benefit of CSI, NEWCO, the COMPANY or the Surviving
Corporation to the extent that such untrue statement (or alleged untrue
statement) was made in, or omission (or alleged omission) occurred in, any
preliminary prospectus and the STOCKHOLDER provided, in writing, corrected
information to CSI counsel and to CSI for inclusion in the final prospectus, and
such information was not so included or properly delivered.

      11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDER at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
STOCKHOLDER as a result of or arising from (i) any breach by CSI or NEWCO of
their representations and warranties set forth herein or on the schedules or
certificates attached hereto, (ii) any nonfulfillment of any agreement on the
part of CSI or NEWCO under this Agreement, (iii) any liabilities which the
STOCKHOLDER may incur due to CSI's or NEWCO's failure to be responsible for the
liabilities and obligations of the COMPANY as provided in Section 1 hereof
(except to the extent that CSI or NEWCO has claims against the STOCKHOLDER by
reason of such liabilities); or (iv) any liability under the 1933 Act, the 1934
Act or other Federal or state law or regulation, at common law or otherwise,
arising out of or based upon any untrue statement or alleged untrue

                                    -56-

statement of a material fact relating to CSI, NEWCO or any of the Other Founding
Companies contained in any preliminary prospectus, the Registration Statement or
any prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or arising out of or based upon any omission or alleged omission to
state therein a material fact relating to CSI or NEWCO or any of the Other
Founding Companies required to be stated therein or necessary to make the
statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has knowledge of any claim by a
person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified Party
of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or control. All Indemnified Parties shall use the same counsel, which
shall be the counsel selected by Indemnifying Party, provided that if counsel to
the Indemnifying Party shall have a conflict of interest that prevents counsel
for the Indemnifying Party from representing Indemnified Party, Indemnified
Party shall have the right to participate in such matter through counsel of its
own

                                    -57-

choosing and Indemnifying Party will reimburse the Indemnified Party for the
reasonable expenses of its counsel. After the Indemnifying Party has notified
the Indemnified Party of its intention to undertake to defend or settle any such
asserted liability, and for so long as the Indemnifying Party diligently pursues
such defense, the Indemnifying Party shall not be liable for any additional
legal expenses incurred by the Indemnified Party in connection with any defense
or settlement of such asserted liability, except (i) as set forth in the
preceding sentence and (ii) to the extent such participation is requested by the
Indemnifying Party, in which event the Indemnified Party shall be reimbursed by
the Indemnifying Party for reasonable additional legal expenses and
out-of-pocket expenses. If the Indemnifying Party desires to accept a final and
complete settlement of any such Third Person claim and the Indemnified Party
refuses to consent to such settlement, then the Indemnifying Party's liability
under this Section with respect to such Third Person claim shall be limited to
the amount so offered in settlement by said Third Person. Upon agreement as to
such settlement between said Third Person and the Indemnifying Party, the
Indemnifying Party shall, in exchange for a complete release from the
Indemnified Party, promptly pay to the Indemnified Party the amount agreed to in
such settlement and the Indemnified Party shall, from that moment on, bear full
responsibility for any additional costs of defense which it subsequently incurs
with respect to such claim and all additional costs of settlement or judgment.
If the Indemnifying Party does not undertake to defend such matter to which the
Indemnified Party is entitled to indemnification hereunder, or fails diligently
to pursue such defense, the Indemnified Party may undertake such defense through
counsel of its choice, at the cost and expense of the Indemnifying Party, and
the Indemnified Party may settle such matter, and the Indemnifying Party shall
reimburse the Indemnified Party for the amount paid in such settlement and any
other liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the

                                    -58-

Indemnified Party otherwise agrees in writing. The parties hereto will make
appropriate adjustments for insurance proceeds in determining the amount of any
indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section 11
shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

      11.5 LIMITATIONS ON INDEMNIFICATION. None of CSI, any NEWCO, any Surviving
Corporation nor any other persons or entities indemnified pursuant to Section
11.1 or 11.2 shall assert any claim for indemnification hereunder against the
STOCKHOLDER until such time as, and solely to the extent that, the aggregate of
all claims which such persons may have against such the STOCKHOLDER shall exceed
the greater of (a) 1.0% of the sum of the cash paid to STOCKHOLDER plus the
value of the CSI Stock delivered to STOCKHOLDER (calculated as provided in this
Section 11.5) or (b) $50,000 (the "Indemnification Threshold"). STOCKHOLDER
shall not assert any claim for indemnification hereunder against CSI or any
NEWCO until such time as, and solely to the extent that, the aggregate of all
claims which STOCKHOLDER may have against CSI or any or all NEWCOs shall exceed
$50,000.

      No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

      Notwithstanding any other term of this Agreement, no STOCKHOLDER shall be
liable under this Section 11 for an amount which exceeds the amount of proceeds
received by such STOCKHOLDER in connection with the Merger. For purposes of
calculating the value of the CSI Stock received by a STOCKHOLDER, CSI Stock
shall be valued at its initial public offering price as set forth in the
Registration Statement. It is hereby understood and agreed that a

                                    -59-

STOCKHOLDER may satisfy an indemnification obligation through payment of a
combination of stock and cash in proportion equal to the proportion of stock and
cash received by such STOCKHOLDER in connection with the Merger, valued as
described immediately above.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION.This Agreement may be terminated (it being understood and
agreed that, for purposes of this Section 12, the term "COMPANY" means both of
the COMPANIES which shall, for purposes of this Section 12, act only in unison)

      (i)   by mutual consent of the boards of directors of CSI and the COMPANY;

      (ii) by the STOCKHOLDER or the COMPANY (acting through its board of
directors), on the one hand, or by CSI (acting through its board of directors),
on the other hand, if the transactions contemplated by this Agreement to take
place at the Closing shall not have been consummated by September 30, 1997,
unless the failure of such transactions to be consummated is due to the willful
failure of the party seeking to terminate this Agreement to perform any of its
obligations under this Agreement to the extent required to be performed by it
prior to or on the Funding and Consummation Date;

      (iii) by the STOCKHOLDER or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due and timely performance of any of the covenants or
agreements contained herein, and the curing of such default shall not have been
made on or before the Funding and Consummation Date or by the STOCKHOLDERS or
the COMPANY, if the conditions set forth in Section 8 hereof have not been
satisfied or waived as of the Closing Date or the Funding and Consummation Date,
as applicable, or by CSI, if the conditions set forth in Section 9 hereof have
not been satisfied or waived as of the Closing Date or the Funding and
Consummation Date, as applicable;

      (iv)  pursuant to Section 7.8 hereof; or

      (v)   pursuant to Section 4 hereof.

                                    -60-

      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. The STOCKHOLDER will not, for a period of five
(5) years following the Funding and Consummation Date, for any reason
whatsoever, directly or indirectly, for himself or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

      (i) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial capacity, whether as an employee, independent
contractor, consultant or advisor, or as a sales representative, in any heating,
ventilating or air conditioning services business in direct competition with CSI
or any of the subsidiaries thereof, within 100 miles of where the COMPANY or any
of its subsidiaries conducted business prior to the effectiveness of the Merger
(the "Territory");

      (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the subsidiaries
thereof), provided that the STOCKHOLDER shall be permitted to call upon and hire
any member of his immediate family;

      (iii) call upon any person or entity which is, at that time, or which has
been, within one (1) year prior to the Funding and Consummation Date, a customer
of CSI (including the subsidiaries thereof), of the COMPANY or of any of the
Other Founding Companies within the Territory for the

                                    -61-

purpose of soliciting or selling products or services in direct competition with
CSI within the Territory;

      (iv) call upon any prospective acquisition candidate, on the STOCKHOLDER'S
own behalf or on behalf of any competitor in the heating, ventilation or air
conditioning services business, which candidate, to the actual knowledge of the
STOCKHOLDER after due inquiry, was called upon by CSI (including the
subsidiaries thereof) or for which, to the actual knowledge of such STOCKHOLDER
after due inquiry, CSI (or any subsidiary thereof) made an acquisition analysis,
for the purpose of acquiring such entity; or

      (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit the STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to CSI for which it would
have no other adequate remedy, the STOCKHOLDER agrees that the foregoing
covenant may be enforced by CSI in the event of breach by the STOCKHOLDER, by
injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDER in light of the activities and business of CSI (including the
subsidiaries thereof) on the date of the execution of this Agreement and the
current plans of CSI.

                                    -62-

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of the STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of the STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which the
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

      13.6 MATERIALITY. The COMPANY and the STOCKHOLDER hereby agree that this
covenant is a material and substantial part of this transaction.

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1 STOCKHOLDER. The STOCKHOLDER recognizes and acknowledges that he had
in the past, currently has, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. The

                                    -63-

STOCKHOLDER agrees that he will not disclose such confidential information to
any person, firm, corporation, association or other entity for any purpose or
reason whatsoever, except (a) to authorized representatives of CSI, (b)
following the Closing, such information may be disclosed by the STOCKHOLDER as
is required in the course of performing his duties for CSI or the Surviving
Corporation and (c) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, unless (i) such information becomes known to the public generally through
no fault of the STOCKHOLDER, (ii) disclosure is required by law or the order of
any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii), the STOCKHOLDER shall,
if possible, give prior written notice thereof to CSI and provide CSI with the
opportunity to contest such disclosure, or (iii) the disclosing party reasonably
believes that such disclosure is required in connection with the defense of a
lawsuit against the disclosing party. In the event of a breach or threatened
breach by the STOCKHOLDER of the provisions of this Section, CSI shall be
entitled to an injunction restraining the STOCKHOLDER from disclosing, in whole
or in part, such confidential information. Nothing herein shall be construed as
prohibiting CSI from pursuing any other available remedy for such breach or
threatened breach, including the recovery of damages. In the event the
transactions contemplated by this Agreement are not consummated, STOCKHOLDER
shall have none of the above-mentioned restrictions on their ability to
disseminate confidential information with respect to the COMPANY.

      14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they had
in the past and currently have access to certain confidential information of the
COMPANY, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other

                                    -64-

advisers, provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 14.1, (c) to the Other Founding
Companies and their representatives pursuant to Section 7.1(a), unless (i) such
information becomes known to the public generally through no fault of CSI or
NEWCO, (ii) disclosure is required by law or the order of any governmental
authority under color of law, provided, that prior to disclosing any information
pursuant to this clause (ii), CSI and NEWCO shall, if possible, give prior
written notice thereof to the COMPANY and the STOCKHOLDER and provide the
COMPANY and the STOCKHOLDER with the opportunity to contest such disclosure, or
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, and
(d) to the public to the extent necessary or advisable in connection with the
filing of the Registration Statement and the IPO and the securities laws
applicable thereto and to the operation of CSI as a publicly held entity after
the IPO. In the event of a breach or threatened breach by CSI or NEWCO of the
provisions of this Section, the COMPANY and the STOCKHOLDER shall be entitled to
an injunction restraining CSI and NEWCO from disclosing, in whole or in part,
such confidential information. Nothing herein shall be construed as prohibiting
the COMPANY and the STOCKHOLDER from pursuing any other available remedy for
such breach or threatened breach, including the recovery of damages.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Funding and Consummation Date.

15.   TRANSFER RESTRICTIONS

                                    -65-

      15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDER or family members, the trustees of
which so agree), for a period of one year from the Closing, except pursuant to
Section 17 hereof, the STOCKHOLDER shall not sell, assign, exchange, transfer,
encumber, pledge, distribute, appoint, or otherwise dispose of any shares of CSI
Stock as described in Section 3.1 received by the STOCKHOLDER in the Merger. The
certificates evidencing the CSI Stock delivered to the STOCKHOLDER pursuant to
Section 3 of this Agreement will bear a legend substantially in the form set
forth below and containing such other information as CSI may deem necessary or
appropriate: THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR
OTHERWISE DISPOSED OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO
ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE,
DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION PRIOR TO THE FIRST ANNIVERSARY OF
CLOSING DATE. UPON THE WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE
ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH
THE TRANSFER AGENT) AFTER THE DATE SPECIFIED ABOVE.

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The STOCKHOLDER acknowledges that the shares of
CSI Stock to be delivered to the STOCKHOLDER pursuant to this Agreement have not
been and will not be registered under the Act (except as provided in Section 17
hereof) and therefore may not be resold without compliance with the Act. The CSI
Stock to be acquired by the STOCKHOLDER pursuant to this Agreement is being
acquired solely for his own account, for investment purposes

                                    -66-

only, and with no present intention of distributing, selling or otherwise
disposing of it in connection with a distribution. The STOCKHOLDER covenants,
warrants and represents that none of the shares of CSI Stock issued to the
STOCKHOLDER will be offered, sold, assigned, pledged, hypothecated, transferred
or otherwise disposed of except after full compliance with all of the applicable
provisions of the Act and the rules and regulations of the SEC. All the CSI
Stock shall bear the following legend in addition to the legend required under
Section 15 of this Agreement:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

      16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDER is able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and has such
knowledge and experience in financial and business matters that he is capable of
evaluating the merits and risks of the proposed investment in the CSI Stock. The
STOCKHOLDER has had an adequate opportunity to ask questions and receive answers
from the officers of CSI concerning any and all matters relating to the
transactions described herein including, without limitation, the background and
experience of the current and proposed officers and directors of CSI, the plans
for the operations of the business of CSI, the business, operations and
financial condition of the Founding Companies other than the COMPANY, and any
plans for additional acquisitions and the like. The STOCKHOLDER has asked any
and all questions in the nature described in the preceding sentence and all
questions have been answered to his satisfaction.

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public

                                    -67-

offering, other than (i) any shelf registration of shares to be used as
consideration for acquisitions of additional businesses by CSI and (ii)
registrations relating to employee benefit plans, CSI shall give the STOCKHOLDER
prompt written notice of its intent to do so. Upon the written request of the
STOCKHOLDER given within 30 days after receipt of such notice, CSI shall cause
to be included in such registration all of the CSI Stock issued to the
STOCKHOLDER pursuant to this Agreement (including any stock issued as (or
issuable upon the conversion or exchange of any convertible security, warrant,
right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) which the STOCKHOLDER requests, provided that CSI shall have the right to
reduce the number of shares included in such registration to the extent that
inclusion of such shares could, in the opinion of tax counsel to CSI or its
independent auditors, jeopardize the status of the transactions contemplated
hereby and by the Registration Statement as a tax-free organization. In
addition, if CSI is advised in writing in good faith by any managing underwriter
of an underwritten offering of the securities being offered pursuant to any
registration statement under this Section 17.1 that the number of shares to be
sold by persons other than CSI is greater than the number of such shares which
can be offered without adversely affecting the offering, CSI may reduce pro rata
the number of shares offered for the accounts of such persons (based upon the
number of shares held by such person) to a number deemed satisfactory by such
managing underwriter, provided, that, for each such offering made by CSI after
the IPO, such reduction shall be made first by reducing the number of shares to
be sold by persons other than CSI, the STOCKHOLDER and the stockholders of the
Other Founding Companies (collectively, the STOCKHOLDER and the stockholders of
the other Founding Companies being referred to herein as the "Founding
Stockholders"), and thereafter, if a further reduction is required, by reducing
the number of shares to be sold by the Founding Stockholders.

      17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year after
the Closing and prior to the date three years after the Closing, the holders of
a majority of the shares of CSI Stock issued to the Founding Stockholders
pursuant to this Agreement and the Other Agreements

                                    -68-

which have not been previously registered or sold and which are not entitled to
be sold under Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act may request in writing that CSI file a registration statement
under the 1933 Act covering the registration of the shares of CSI Stock issued
to the STOCKHOLDER pursuant to this Agreement and the Other Agreements
(including any stock issued as (or issuable upon the conversion or exchange of
any convertible security, warrant, right or other security which is issued by
CSI as) a dividend or other distribution with respect to, or in exchange for, or
in replacement of such CSI Stock) then held by such Founding Stockholders (a
"Demand Registration"). Within ten (10) days of the receipt of such request, CSI
shall give written notice of such request to all other Founding Stockholders and
shall, as soon as practicable but in no event later than 45 days after notice
from the STOCKHOLDER, file and use its best efforts to cause to become effective
a registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

      Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the date on which CSI
would otherwise be required to make such filing pursuant to the foregoing
paragraph.

      If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective date of such registration unless CSI is no longer proceeding
diligently to effect such registration; provided that CSI shall provide the
Founding Stockholders the right to participate in such public offering pursuant
to, and subject to, Section 17.1 hereof.

                                    -69-

      17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with the
registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Sections 17.1 and 17.2 covering an underwritten registered offering, CSI and
each participating holder agree to enter into a written agreement with the
managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
managing underwriters and companies of CSI's size and investment stature,
including indemnification.

      17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by the STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to the STOCKHOLDER.

      17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

                                    -70-

            (i) make and keep public information regarding CSI available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of CSI under the 1933 Act and the 1934 Act at any time
      after it has become subject to such reporting requirements; and

            (iii) so long as a STOCKHOLDER owns any restricted CSI Common Stock,
      furnish to each STOCKHOLDER forthwith upon written request a written
      statement by CSI as to its compliance with the reporting requirements of
      Rule 144 (at any time from and after 90 days following the effective date
      of the Registration Statement, and of the 1933 Act and the 1934 Act (at
      any time after it has become subject to such reporting requirements), a
      copy of the most recent annual or quarterly report of CSI, and such other
      reports and documents so filed as a STOCKHOLDER may reasonably request in
      availing itself of any rule or regulation of the SEC allowing a
      STOCKHOLDER to sell any such shares without registration.

      18.   GENERAL

      18.1 COOPERATION. Each COMPANY, STOCKHOLDER, CSI and NEWCO shall each
deliver or cause to be delivered to the other on the Funding and Consummation
Date, and at such other times and places as shall be reasonably agreed to, such
additional instruments as the other may reasonably request for the purpose of
carrying out this Agreement. Each COMPANY will cooperate and use its reasonable
efforts to have the present officers, directors and employees of such COMPANY
cooperate with CSI on and after the Funding and Consummation Date in furnishing
information, evidence, testimony and other assistance in connection with any tax
return filing obligations, actions, proceedings, arrangements or disputes of any
nature with respect to matters pertaining to all periods prior to the Funding

      18.3 ENTIRE AGREEMENT. This Agreement (including the schedules, exhibits
and annexes attached hereto) and the documents delivered pursuant hereto
constitute the entire agreement and understanding among the STOCKHOLDER, each
COMPANY, each NEWCO and CSI and supersede any prior agreement and understanding
relating to the subject matter of this Agreement. This Agreement, upon

enforceable in accordance with its terms and may be modified or amended only by
a written instrument executed by the STOCKHOLDER, each COMPANY, each NEWCO and
CSI, acting through their respective officers or trustees, duly authorized by
their respective Boards of Directors. Any disclosure made on any Schedule
delivered pursuant hereto shall be deemed to have been disclosed for purposes of
any other Schedule required hereby, provided that each COMPANY shall make a good
faith effort to cross reference disclosure, as necessary or advisable, between
related Schedules.

      18.4 COUNTERPARTS. This Agreement may be executed simultaneously in two
(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

      18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each party
represents and warrants that it employed no broker or agent in connection with
this transaction and agrees to indemnify the other parties hereto against all
loss, cost, damages or expense arising out of claims for fees or commission of
brokers employed or alleged to have been employed by such indemnifying party.

      18.6 EXPENSES. Whether or not the transactions herein contemplated shall

similar taxes and fees ("Transfer Taxes") imposed in connection with the Merger,
other than Transfer Taxes, if any, imposed by the State of Delaware. The
STOCKHOLDER shall file all necessary documentation and Returns with respect to

payable pursuant to Section 2 hereof, and will assume all tax risks and
liabilities of the STOCKHOLDER in connection with the transactions contemplated
hereby.

this Agreement, and, subject to the provisions of Section 7.8, at the sole
option of CSI, the truth and accuracy of any and all warranties and
representations of the COMPANY, or on behalf of the COMPANY and of STOCKHOLDERS
at the date of this Agreement and on the Closing Date and on the Funding and
Consummation Date, shall be a precondition to the consummation of this

and (iii) that the decision of STOCKHOLDERS to enter into this Agreement, or to
vote in favor of or consent to the proposed Merger, has been or will be made

        7.7 NOTIFICATION OF CERTAIN MATTERS. The STOCKHOLDERS and the COMPANY
shall give prompt notice to CSI of (i) the occurrence or non-occurrence of any

non-occurrence of which would be

                                      -41-


likely to cause any representation or warranty of CSI or NEWCO contained herein

such party shall have the continuing obligation until 24 hours prior to the

promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the COMPANY that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless CSI and
a majority of the Founding Companies other than the COMPANY consent to such
amendment or supplement; and provided further, that no amendment or supplement
to a Schedule prepared by CSI or NEWCO that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless a

all purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other

to such amendment or supplement, which consent shall have been deemed given by
CSI or any Founding Company if no response is received within 24 hours following
receipt of notice of such amendment or supplement (or sooner if required by the
circumstances under which such consent is requested), but the COMPANY does not
give its consent, the COMPANY may terminate this Agreement pursuant to Section
12.1(iv) hereof. In the event that the COMPANY seeks to amend or supplement a
Schedule pursuant to this Section 7.8, and CSI and a majority of the Other
Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. In the event that CSI or NEWCO seeks to amend or supplement a
Schedule pursuant to this Section 7.8 and a majority of the Founding Companies
do not consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the

any material respect, and to provide the information needed to correct such
inaccuracy. Insofar as the information relates solely to the COMPANY or the
STOCKHOLDERS, the COMPANY represents and warrants as to such information with
respect to itself, and each Stockholder represents and warrants, as to such
information with respect to the COMPANY and himself or herself, that the
Registration Statement will not include an untrue statement of a material fact

make the statements therein, in light of the circumstances under which they were
made, not misleading.

one or more filings under the Hart-Scott Act may be required in connection with
the transactions contemplated herein. If it is determined by the parties to this
Agreement that filings under the Hart-Scott Act are required, then: (i) each of
the parties hereto agrees to cooperate and use its best efforts to comply with
the Hart-Scott Act, (ii) such compliance by the STOCKHOLDERS and the COMPANY

                                      -52-


        reasonably may request in filing any Return, amended Return or claim for
        refund, determining a liability for Taxes or a right to refund of Taxes
        or in conducting any audit or other proceeding in respect of Taxes. Such
        cooperation and information shall include providing copies of all
        relevant portions of relevant Returns, together with relevant
        accompanying schedules and relevant work papers, relevant documents
        relating to rulings or other determinations by Taxing Authorities and
        relevant records concerning the ownership and Tax basis of property,
        which such party may possess. Each party shall make its employees
        reasonably available on a mutually convenient basis at its cost to
        provide explanation of any documents or information so provided. Subject
        to the preceding sentence, each party required to file Returns pursuant
        to this Agreement shall bear all costs of filing such Returns.

               (iv) Each of the COMPANY, NEWCO, CSI and each STOCKHOLDER shall
        comply with the tax reporting requirements of Section 1.351-3 of the
        Treasury Regulations promulgated under the Code, and treat the
        transaction as a tax-free contribution under Section 351(a) of the Code
        subject to gain, if any, recognized on the receipt of cash or other
        property under Section 351(b) of the Code. 10.4 DIRECTORS. The persons
        named in the draft of the Registration Statement shall be

appointed as directors and elected as officers of CSI, as and to the extent set
forth in the draft of the Registration Statement, promptly following the Funding
and Consummation Date. This provision shall not imply that the STOCKHOLDERS have
any power or duty to elect officers of CSI.

        10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation to provide
replacement plans that have the same terms and provisions as the existing plans,
provided, further, that any new health insurance plan shall provide for coverage
for preexisting conditions. On

                                      -53-


the Funding and Consummation Date, the employees of the COMPANY will be the
employees of the Surviving Corporation (provided that this provision is for
purposes of clarifying that the Merger, in and of itself, will not have any
impact on the employment status of any employee and provided, further that this
provision shall not in any way limit the management rights of the Surviving
Corporation or CSI to assess workforce needs and make appropriate adjustments as
necessary or desirable within their discretion subject to applicable laws and
collective bargaining agreements).

        10.6 DIVIDENDS. If the COMPANY is an S corporation, the COMPANY may pay
to each STOCKHOLDER as a dividend the full amount of his or her "accumulated
adjustments account" (as defined in Section 1368(e) of the Code) as of the
Balance Sheet Date, and may also pay to the STOCKHOLDERS as a dividend the full
amount of the COMPANY's earnings taxable to such STOCKHOLDERS for the period
after the Balance Sheet Date to the Funding and Consummation Date. If the
COMPANY is a C corporation, the COMPANY may pay to the STOCKHOLDERS as a
dividend the full amount of the COMPANY's earnings for the period after the
Balance Sheet Date to the Funding and Consummation Date. The COMPANY may borrow
funds to the extent necessary to make the payments contemplated by this Section
10.6 and to the extent necessary to ensure that the COMPANY has cash on hand to
adequately fund operations on the Funding and Consummation Date.

11.     INDEMNIFICATION

        The STOCKHOLDERS, CSI and NEWCO each make the following covenants that
are applicable to them, respectively:

        11.1   GENERAL INDEMNIFICATION BY THE STOCKHOLDERS.  The STOCKHOLDERS

covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless CSI, NEWCO, the COMPANY and the Surviving Corporation
at all times, from and after the date of this Agreement until the Expiration
Date, from and against all claims, damages, actions, suits, proceedings,
demands, assessments, adjustments, costs and expenses (including specifically,
but

                                      -54-


without limitation, reasonable attorneys' fees and expenses of investigation)
incurred by CSI, NEWCO, the COMPANY or the Surviving Corporation as a result of
or arising from (i) any breach of the representations and warranties of the
STOCKHOLDERS or the COMPANY set forth herein or on the schedules or certificates
delivered in connection herewith, (ii) any breach of any agreement on the part
of the STOCKHOLDERS or the COMPANY under this Agreement, or (iii) any liability
under the 1933 Act, the 1934 Act or other Federal or state law or regulation, at
common law or otherwise, arising out of or based upon any untrue statement or
alleged untrue statement of a material fact relating to the COMPANY or the
STOCKHOLDERS, and provided to CSI or its counsel by the COMPANY or the
STOCKHOLDERS (but in the case of the STOCKHOLDERS, only if such statement was
provided in writing) contained in the Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto, or
arising out of or based upon any omission or alleged omission to state therein a
material fact relating to the COMPANY or the STOCKHOLDERS required to be stated
therein or necessary to make the statements therein not misleading; provided,
however, that such indemnity shall not inure to the benefit of CSI, NEWCO, the
COMPANY or the Surviving Corporation to the extent that such untrue statement
(or alleged untrue statement) was made in, or omission (or alleged omission)
occurred in, any preliminary prospectus and the STOCKHOLDERS provided, in
writing, corrected information to CSI counsel and to CSI for inclusion in the
final prospectus, and such information was not so included or properly
delivered, and provided further, that no STOCKHOLDER shall be liable for any
indemnification obligation pursuant to this Section 11.1 to the extent
attributable to a breach of any representation, warranty or agreement made
herein individually by any other STOCKHOLDER.

        11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDERS at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the

                                      -55-


STOCKHOLDERS as a result of or arising from (i) any breach by CSI or NEWCO of
their representations and warranties set forth herein or on the schedules or
certificates attached hereto, (ii) any nonfulfillment of any agreement on the
part of CSI or NEWCO under this Agreement, or (iii) any liabilities which the
STOCKHOLDERS may incur due to CSI's or NEWCO's failure to be responsible for the
liabilities and obligations of the COMPANY as provided in Section 1 hereof
(except to the extent that CSI or NEWCO has claims against the STOCKHOLDERS by
reason of such liabilities); or (iv) any liability under the 1933 Act, the 1934
Act or other Federal or state law or regulation, at common law or otherwise,
arising out of or based upon any untrue statement or alleged untrue statement of
a material fact relating to CSI, NEWCO or any of the Other Founding Companies
contained in any preliminary prospectus, the Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or arising out of or based upon any omission or alleged omission to
state therein a material fact relating to CSI or NEWCO or any of the Other
Founding Companies required to be stated therein or necessary to make the
statements therein not misleading.

        11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified

                                      -56-


Party of its intention to do so, and the Indemnified Party shall cooperate with
the Indemnifying Party and its counsel in the defense thereof and in any
settlement thereof. Such cooperation shall include, but shall not be limited to,
furnishing the Indemnifying Party with any books, records or information
reasonably requested by the Indemnifying Party that are in the Indemnified
Party's possession or control. All Indemnified Parties shall use the same
counsel, which shall be the counsel selected by Indemnifying Party, provided
that if counsel to the Indemnifying Party shall have a conflict of interest that
prevents counsel for the Indemnifying Party from representing Indemnified Party,
Indemnified Party shall have the right to participate in such matter through
counsel of its own choosing and Indemnifying Party will reimburse the
Indemnified Party for the reasonable expenses of its counsel. After the
Indemnifying Party has notified the Indemnified Party of its intention to
undertake to defend or settle any such asserted liability, and for so long as
the Indemnifying Party diligently pursues such defense, the Indemnifying Party
shall not be liable for any additional legal expenses incurred by the
Indemnified Party in connection with any defense or settlement of such asserted
liability, except (i) as set forth in the preceding sentence and (ii) to the
extent such participation is requested by the Indemnifying Party, in which event
the Indemnified Party shall be reimbursed by the Indemnifying Party for
reasonable additional legal expenses and out-of-pocket expenses. If the
Indemnifying Party desires to accept a final and complete settlement of any such
Third Person claim and the Indemnified Party refuses to consent to such
settlement, then the Indemnifying Party's liability under this Section with
respect to such Third Person claim shall be limited to the amount so offered in
settlement by said Third Person. Upon agreement as to such settlement between
said Third Person and the Indemnifying Party, the Indemnifying Party shall, in
exchange for a complete release from the Indemnified Party, promptly pay to the
Indemnified Party the amount agreed to in such settlement and the Indemnified
Party shall, from that moment on, bear full responsibility for any additional
costs of defense which it subsequently incurs with respect to such claim and all
additional costs of settlement or judgment. If the Indemnifying Party does not
undertake to defend such matter to which the Indemnified Party is entitled to
indemnification

                                      -57-


hereunder, or fails diligently to pursue such defense, the Indemnified Party may
undertake such defense through counsel of its choice, at the cost and expense of
the Indemnifying Party, and the Indemnified Party may settle such matter, and
the Indemnifying Party shall reimburse the Indemnified Party for the amount paid
in such settlement and any other liabilities or expenses incurred by the
Indemnified Party in connection therewith, provided, however, that under no
circumstances shall the Indemnified Party settle any Third Person claim without
the written consent of the Indemnifying Party, which consent shall not be
unreasonably withheld or delayed. All settlements hereunder shall effect a
complete release of the Indemnified Party, unless the Indemnified Party
otherwise agrees in writing. The parties hereto will make appropriate
adjustments for insurance proceeds in determining the amount of any
indemnification obligation under this Section.

        11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section
11 shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

        11.5 LIMITATIONS ON INDEMNIFICATION. CSI, NEWCO, the Surviving
Corporation and the other persons or entities indemnified pursuant to Section
11.1 or 11.2 shall not assert any claim for indemnification hereunder against
the STOCKHOLDERS until such time as, and solely to the extent that, the
aggregate of all claims which such persons may have against such the
STOCKHOLDERS shall exceed the greater of (a) 1.0% of the sum of the cash paid to
STOCKHOLDERS plus the value of the CSI Stock delivered to STOCKHOLDERS
(calculated as provided in this Section 11.5) or (b) $50,000 (the
"Indemnification Threshold"). STOCKHOLDERS shall not assert any claim for
indemnification hereunder against CSI or NEWCO until such time as, and solely to
the extent that, the aggregate of all claims which STOCKHOLDERS may have against
CSI or NEWCO shall exceed $50,000.

                                      -58-


        No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

        Notwithstanding any other term of this Agreement, no STOCKHOLDER shall
be liable under this Section 11 for an amount which exceeds the amount of
proceeds received by such STOCKHOLDER in connection with the Merger. For
purposes of calculating the value of the CSI Stock received by a STOCKHOLDER,
CSI Stock shall be valued at its initial public offering price as set forth in
the Registration Statement. It is hereby understood and agreed that a
STOCKHOLDER may satisfy an indemnification obligation through payment of a
combination of stock and cash in proportion equal to the proportion of stock and
cash received by such STOCKHOLDER in connection with the Merger, valued as
described immediately above.

12.     TERMINATION OF AGREEMENT

        12.1 TERMINATION. This Agreement may be terminated at any time prior to
the Funding and Consummation Date solely:

        (i) by mutual consent of the boards of directors of CSI and the COMPANY;

        (ii) by the STOCKHOLDERS or the COMPANY (acting through its board of
directors),on the one hand, or by CSI (acting through its board of directors),
on the other hand, if the transactions contemplated by this Agreement to take
place at the Closing shall not have been consummated by September 30, 1997,
unless the failure of such transactions to be consummated is due to the willful
failure of the party seeking to terminate this Agreement to perform any of its
obligations under this Agreement to the extent required to be performed by it
prior to or on the Funding and Consummation Date;

        (iii) by the STOCKHOLDERS or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due and timely performance of any of the covenants or
agreements contained herein, and the curing of such default shall not have been
made on or before the Funding and Consummation Date or by the

                                      -59-


STOCKHOLDERS, or the COMPANY, if the conditions set forth in Section 8 hereof
have not been satisfied or waived as of the Closing Date or the Funding and
Consummation Date, as applicable, or by CSI, if the conditions set forth in
Section 9 hereof have not been satisfied or waived as of the Closing Date or the
Funding and Consummation Date, as applicable;

        (iv)   pursuant to Section 7.8 hereof; or

        (v)    pursuant to Section 4 hereof.

        12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.     NONCOMPETITION

        13.1 PROHIBITED ACTIVITIES. The STOCKHOLDERS will not, for a period of
five (5) years following the Funding and Consummation Date, for any reason
whatsoever, directly or indirectly, for themselves or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

        (i) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial capacity, whether as an employee, independent
contractor, consultant or advisor, or as a sales representative, in any heating,
ventilating or air conditioning services business in direct competition with CSI
or any of the subsidiaries thereof, within 100 miles of where the COMPANY or any
of its subsidiaries conducted business prior to the effectiveness of the Merger
(the "Territory");

        (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the

                                      -60-


subsidiaries thereof), provided that each STOCKHOLDER shall be permitted to call
upon and hire any member of his or her immediate family;

        (iii) call upon any person or entity which is, at that time, or which
has been, within one (1) year prior to the Funding and Consummation Date, a
customer of CSI (including the subsidiaries thereof), of the COMPANY or of any
of the Other Founding Companies within the Territory for the purpose of
soliciting or selling products or services in direct competition with CSI within
the Territory;

        (iv) call upon any prospective acquisition candidate, on any
STOCKHOLDER's own behalf or on behalf of any competitor in the heating,
ventilation or air conditioning services business, which candidate, to the
actual knowledge of such STOCKHOLDER after due inquiry, was called upon by CSI
(including the subsidiaries thereof) or for which, to the actual knowledge of
such STOCKHOLDER after due inquiry, CSI (or any subsidiary thereof) made an
acquisition analysis, for the purpose of acquiring such entity; or

        (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

        Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

        13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to CSI for which it would
have no other adequate remedy, each STOCKHOLDER agrees that the foregoing
covenant may be enforced by CSI in the event of breach by such STOCKHOLDER, by
injunctions and restraining orders.

                                      -61-


        13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDERS in light of the activities and business of CSI (including the
subsidiaries thereof) on the date of the execution of this Agreement and the
current plans of CSI.

        13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

        13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of each STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which such
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

        13.6 MATERIALITY. The COMPANY and the STOCKHOLDERS hereby agree that
this covenant is a material and substantial part of this transaction.

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

                                      -62-


        14.1 STOCKHOLDERS. The STOCKHOLDERS recognize and acknowledge that they
had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. The STOCKHOLDERS agree that they
will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except (a) to authorized representatives of CSI, (b) following the Closing, such
information may be disclosed by the STOCKHOLDERS as is required in the course of
performing their duties for CSI or the Surviving Corporation and (c) to counsel
and other advisers, provided that such advisers (other than counsel) agree to
the confidentiality provisions of this Section 14.1, unless (i) such information
becomes known to the public generally through no fault of the STOCKHOLDERS, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), the STOCKHOLDERS shall, if possible, give prior written notice
thereof to CSI and provide CSI with the opportunity to contest such disclosure,
or (iii) the disclosing party reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party. In the event of a breach or threatened breach by any of the STOCKHOLDERS
of the provisions of this Section, CSI shall be entitled to an injunction
restraining such STOCKHOLDERS from disclosing, in whole or in part, such
confidential information. Nothing herein shall be construed as prohibiting CSI
from pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. In the event the transactions contemplated by
this Agreement are not consummated, STOCKHOLDERS shall have none of the
above-mentioned restrictions on their ability to disseminate confidential
information with respect to the COMPANY.

        14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they
had in the past and currently have access to certain confidential information of
the COMPANY, such as

                                      -63-


operational policies, and pricing and cost policies that are valuable, special
and unique assets of the COMPANY's business. CSI and NEWCO agree that, prior to
the Closing, or if the Transactions contemplated by this Agreement are not
consummated, they will not disclose such confidential information to any person,
firm, corporation, association or other entity for any purpose or reason
whatsoever, except (a) to authorized representatives of the COMPANY, (b) to
counsel and other advisers, provided that such advisers (other than counsel)
agree to the confidentiality provisions of this Section 14.1, (c) to the Other
Founding Companies and their representatives pursuant to Section 7.1(a), unless
(i) such information becomes known to the public generally through no fault of
CSI or NEWCO, (ii) disclosure is required by law or the order of any
governmental authority under color of law, provided, that prior to disclosing
any information pursuant to this clause (ii), CSI and NEWCO shall, if possible,
give prior written notice thereof to the COMPANY and the STOCKHOLDERS and
provide the COMPANY and the STOCKHOLDERS with the opportunity to contest such
disclosure, or (iii) the disclosing party reasonably believes that such
disclosure is required in connection with the defense of a lawsuit against the
disclosing party, and (d) to the public to the extent necessary or advisable in
connection with the filing of the Registration Statement and the IPO and the
securities laws applicable thereto and to the operation of CSI as a publicly
held entity after the IPO. In the event of a breach or threatened breach by CSI
or NEWCO of the provisions of this Section, the COMPANY and the STOCKHOLDERS
shall be entitled to an injunction restraining CSI and NEWCO from disclosing, in
whole or in part, such confidential information. Nothing herein shall be
construed as prohibiting the COMPANY and the STOCKHOLDERS from pursuing any
other available remedy for such breach or threatened breach, including the
recovery of damages.

        14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the

                                      -64-


parties hereto agree that, in the event of a breach by any of them of the
foregoing covenants, the covenant may be enforced against the other parties by
injunctions and restraining orders.

        14.4 SURVIVAL. The obligations of the parties under this Article 14
shall survive the termination of this Agreement for a period of five years from
the Funding and Consummation Date.

15.     TRANSFER RESTRICTIONS

        15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDERS or family members, the trustees
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the STOCKHOLDERS shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of CSI Stock as described in Section 3.1 received by the STOCKHOLDERS in
the Merger. The certificates evidencing the CSI Stock delivered to the
STOCKHOLDERS pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as CSI may deem necessary or appropriate:

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED,
TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED
OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT
OR OTHER DISPOSITION PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE
WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE
THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT)
AFTER THE DATE SPECIFIED ABOVE.

                                      -65-


16.     FEDERAL SECURITIES ACT REPRESENTATIONS

        16.1 COMPLIANCE WITH LAW. The STOCKHOLDERS acknowledge that the shares
of CSI Stock to be delivered to the STOCKHOLDERS pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and may not be resold without compliance with the Act. The CSI Stock
to be acquired by such STOCKHOLDERS pursuant to this Agreement is being acquired
solely for their own respective accounts, for investment purposes only, and with
no present intention of distributing, selling or otherwise disposing of it in
connection with a distribution. The STOCKHOLDERS covenant, warrant and represent
that none of the shares of CSI Stock issued to such STOCKHOLDERS will be
offered, sold, assigned, pledged, hypothecated, transferred or otherwise
disposed of except after full compliance with all of the applicable provisions
of the Act and the rules and regulations of the SEC. All the CSI Stock shall
bear the following legend in addition to the legend required under Section 15 of
this Agreement: THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED
IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

        16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDERS are able to bear
the economic risk of an investment in the CSI Stock to be acquired pursuant to
this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment in the
CSI Stock. The STOCKHOLDERS party hereto have had an adequate opportunity to ask
questions and receive answers from the officers of CSI concerning any and all
matters relating to the transactions described herein including, without
limitation, the background and experience of the current and proposed officers
and directors of CSI, the plans for the operations of the business

                                      -66-


of CSI, the business, operations and financial condition of the Founding
Companies other than the COMPANY, and any plans for additional acquisitions and
the like. The STOCKHOLDERS have asked any and all questions in the nature
described in the preceding sentence and all questions have been answered to
their satisfaction.

17.     REGISTRATION RIGHTS

        17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
each of the STOCKHOLDERS prompt written notice of its intent to do so. Upon the
written request of any of the STOCKHOLDERS given within 30 days after receipt of
such notice, CSI shall cause to be included in such registration all of the CSI
Stock issued to the STOCKHOLDERS pursuant to this Agreement (including any stock
issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) which any such STOCKHOLDER requests, provided that CSI shall
have the right to reduce the number of shares included in such registration to
the extent that inclusion of such shares could, in the opinion of tax counsel to
CSI or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Registration Statement as a tax-free
organization. In addition, if CSI is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1 that the number
of shares to be sold by persons other than CSI is greater than the number of
such shares which can be offered without adversely affecting the offering, CSI
may reduce pro rata the number of shares offered for the accounts of such
persons (based upon the number of shares held by such person) to a number deemed
satisfactory by such managing underwriter, provided, that, for each

                                      -67-


such offering made by CSI after the IPO, such reduction shall be made first by
reducing the number of shares to be sold by persons other than CSI, the
STOCKHOLDERS and the stockholders of the Other Founding Companies (collectively,
the STOCKHOLDERS and the stockholders of the other Founding Companies being
referred to herein as the "Founding Stockholders"), and thereafter, if a further
reduction is required, by reducing the number of shares to be sold by the
Founding Stockholders.

        17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year
after the Closing and prior to the date three years after the Closing, the
holders of a majority of the shares of CSI Stock issued to the Founding
Stockholders pursuant to this Agreement and the Other Agreements which have not
been previously registered or sold and which are not entitled to be sold under
Rule 144(k) (or any similar or successor provision) promulgated under the 1933
Act may request in writing that CSI file a registration statement under the 1933
Act covering the registration of the shares of CSI Stock issued to the
STOCKHOLDERS pursuant to this Agreement and the Other Agreements (including any
stock issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) then held by such Founding Stockholders (a "Demand
Registration"). Within ten (10) days of the receipt of such request, CSI shall
give written notice of such request to all other Founding Stockholders and
shall, as soon as practicable but in no event later than 45 days after notice
from any STOCKHOLDER, file and use its best efforts to cause to become effective
a registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

        Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the

                                      -68-


date on which CSI would otherwise be required to make such filing pursuant to
the foregoing paragraph.

        If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective date of such registration unless CSI is no longer proceeding
diligently to effect such registration; provided that CSI shall provide the
Founding Stockholders the right to participate in such public offering pursuant
to, and subject to, Section 17.1 hereof.

        17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with
the registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

        17.4 UNDERWRITING AGREEMENT. In connection with each registration
pursuant to Sections 17.1 and 17.2 covering an underwritten registered offering,
CSI and each participating holder agree to enter into a written agreement with
the managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such

                                      -69-


managing underwriters and companies of CSI's size and investment stature,
including indemnification.

        17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by any STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to such STOCKHOLDER.

        17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

               (i) make and keep public information regarding CSI available as
        those terms are understood and defined in Rule 144 under the 1933 Act
        for a period of four years beginning 90 days following the effective
        date of the Registration Statement;

               (ii) file with the SEC in a timely manner all reports and other
        documents required of CSI under the 1933 Act and the 1934 Act at any
        time after it has become subject to such reporting requirements; and

               (iii) so long as a STOCKHOLDER owns any restricted CSI Common
        Stock, furnish to each STOCKHOLDER forthwith upon written request a
        written statement by CSI as to its compliance with the reporting
        requirements of Rule 144 (at any time from and after 90 days following
        the effective date of the Registration Statement, and of the 1933 Act
        and the 1934 Act (at any time after it has become subject to such
        reporting requirements), a copy of the most recent annual or quarterly
        report of CSI, and such other reports and documents so filed as a
        STOCKHOLDER may reasonably request in availing itself of any rule or
        regulation of the SEC allowing a STOCKHOLDER to sell any such shares
        without registration.

        18.    GENERAL

        18.1 COOPERATION. The COMPANY, STOCKHOLDERS, CSI and NEWCO shall each
deliver or cause to be delivered to the other on the Funding and Consummation

instruments as the other may reasonably request for the purpose of carrying out
this Agreement. The COMPANY will cooperate and use its reasonable efforts to

effort to cross reference disclosure, as necessary or advisable, between related
Schedules.

(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

        18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each
party represents and warrants that it employed no broker or agent in connection
with this transaction and agrees to indemnify the other parties hereto against

of brokers employed or alleged to have been employed by such indemnifying party.

hereby.

applicable provisions of ERISA and the regulations issued thereunder, as well as
with all other applicable federal, state and local statutes, ordinances and
regulations.

respect to any plan listed on Schedule 5.19 have either been fulfilled in their
entirety or are fully reflected on the balance sheet of the COMPANY as of the
Balance Sheet Date.

        5.20 COMPLIANCE WITH ERISA. All such plans listed on Schedule 5.19 that

        provisions of Title IV of ERISA has been terminated;

        or penalty, or being subject to any statutory lien to secure payment of
        any such liability) with respect to any plan now or heretofore
        maintained or contributed to by any entity other than the COMPANY that

likely to cause any representation or warranty of CSI or NEWCO contained herein

to such amendment or supplement, which consent shall have been deemed given by
CSI or any Founding Company if no response is received within 24 hours following
receipt of notice of such amendment or supplement (or sooner if required by the
circumstances under which such consent is requested), but the COMPANY does not
give its consent, the COMPANY may terminate this Agreement pursuant to Section
12.1(iv) hereof. In the event that the COMPANY seeks to amend or supplement a
Schedule pursuant to this Section 7.8, and CSI and a majority of the Other
Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. In the event that CSI or NEWCO seeks to amend or supplement a
Schedule pursuant to this Section 7.8 and a majority of the Founding Companies
do not consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the
anticipated effectiveness of the Registration Statement.

        7.9 COOPERATION IN PREPARATION OF REGISTRATION STATEMENT. The COMPANY
and STOCKHOLDERS shall furnish or cause to be furnished to CSI and the
Underwriters all of the information concerning the COMPANY and the STOCKHOLDERS
required for inclusion in, and will cooperate with CSI and the Underwriters in
the preparation of, the Registration Statement and the prospectus included
therein (including audited and unaudited financial statements, prepared in
accordance with generally accepted accounting principles, in form suitable for
inclusion in the Registration Statement). The COMPANY and the STOCKHOLDERS agree
promptly to advise CSI if at any time during the period in which a prospectus
relating to the offering is required to be

                                      -43-

delivered under the Securities Act, any information contained in the prospectus
concerning the COMPANY or the STOCKHOLDERS becomes incorrect or incomplete in
any material respect, and to provide the information needed to correct such
inaccuracy. Insofar as the information relates solely to the COMPANY or the
STOCKHOLDERS, the COMPANY represents and warrants as to such information with
respect to itself, and each Stockholder represents and warrants, as to such
information with respect to the COMPANY and himself or herself, that the
Registration Statement will not include an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

        7.10 FINAL FINANCIAL STATEMENTS. The COMPANY shall provide prior to the
Funding and Consummation Date, and CSI shall have had sufficient time to review
the unaudited consolidated balance sheets of the COMPANY as of the end of all
fiscal quarters following the Balance Sheet Date, and the unaudited consolidated
statement of income, cash flows and retained earnings of the COMPANY for all
fiscal quarters ended after the Balance Sheet Date, disclosing no material
adverse change in the financial condition of the COMPANY or the results of its
operations from the financial statements as of the Balance Sheet Date. Such
financial statements shall have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis throughout the
periods indicated (except as noted therein). Except as noted in such financial
statements, all of such financial statements will present fairly the results of
operations of the COMPANY for the periods indicated therein.

        7.11 FURTHER ASSURANCES. The parties hereto agree to execute and

as are made to respond to comments made by the SEC or requirements of any
exchange or automated trading system for which application is made to register
the CSI Stock.

        7.13 COMPLIANCE WITH THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF
1976 (THE "HART-SCOTT ACT"). All parties to this Agreement hereby recognize that

Agreement that filings under the Hart-Scott Act are required, then: (i) each of

                                      -51-

CSI shall maintain unencumbered funds in amounts sufficient to provide for such
pay off, refinancing or retirement, provided that CSI may use such funds for
other purposes, in its sole discretion, with the prior written consent of each
STOCKHOLDER who has not as of that time been released from his or her guarantee
as described above and whose indebtedness as described above has not as of that
time been paid off, refinanced or retired.

        10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as
contemplated by this Agreement or the Registration Statement, after the Funding

                (a) the retirement or reacquisition, directly or indirectly, of
        all or part of the CSI Stock issued in connection with the transactions
        contemplated hereby; or

                (b) the entering into of financial arrangements for the benefit
        of the STOCKHOLDERS.

        10.3   PREPARATION AND FILING OF TAX RETURNS.

               (i) The COMPANY shall, if possible, file or cause to be filed all
        separate Returns of any Acquired Party for all taxable periods that end
        on or before the Funding and Consummation Date. Notwithstanding the
        foregoing, the STOCKHOLDERS shall file or cause to be filed all separate
        federal income Tax Returns (and any State and local Tax Returns filed on
        the basis similar to that of S corporations under federal income Tax
        rules) of any Acquired Party for all taxable periods that end on or
        before the Funding and Consummation Date. Each STOCKHOLDER shall pay or
        cause to be paid all Tax liabilities (in excess of all amounts already
        paid with respect thereto or properly accrued or reserved with respect
        thereto on the COMPANY Financial Statements) shown by such Returns to be
        due.

               (ii) CSI shall file or cause to be filed all separate Returns of,
        or that include, any Acquired Party for all taxable periods ending after
        the Funding and Consummation Date.

                                      -52-

               (iii) Each party hereto shall, and shall cause its subsidiaries
        and affiliates to, provide to each of the other parties hereto such
        cooperation and information as any of them reasonably may request in
        filing any Return, amended Return or claim for refund, determining a
        liability for Taxes or a right to refund of Taxes or in conducting any
        audit or other proceeding in respect of Taxes. Such cooperation and
        information shall include providing copies of all relevant portions of
        relevant Returns, together with relevant accompanying schedules and
        relevant work papers, relevant documents relating to rulings or other
        determinations by Taxing Authorities and relevant records concerning the
        ownership and Tax basis of property, which such party may possess. Each
        party shall make its employees reasonably available on a mutually
        convenient basis at its cost to provide explanation of any documents or
        information so provided. Subject to the preceding sentence, each party
        required to file Returns pursuant to this Agreement shall bear all costs
        of filing such Returns.

               (iv) Each of the COMPANY, NEWCO, CSI and each STOCKHOLDER shall
        comply with the tax reporting requirements of Section 1.351-3 of the
        Treasury Regulations promulgated under the Code, and treat the
        transaction as a tax-free contribution under Section 351(a) of the Code
        subject to gain, if any, recognized on the receipt of cash or other
        property under Section 351(b) of the Code. 10.4 DIRECTORS. The persons
        named in the draft of the Registration Statement shall be appointed as
        directors and elected as officers of CSI, as and to the extent set forth
        in the draft of the Registration Statement, promptly following the
        Funding and Consummation Date. This provision shall not imply that the
        STOCKHOLDERS have any power or duty to elect officers of CSI.

        10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation

                                      -53-

to provide replacement plans that have the same terms and provisions as the
existing plans, provided, further, that any new health insurance plan shall
provide for coverage for preexisting conditions. On the Funding and Consummation
Date, the employees of the COMPANY will be the employees of the Surviving
Corporation (provided that this provision is for purposes of clarifying that the
Merger, in and of itself, will not have any impact on the employment status of
any employee and provided, further that this provision shall not in any way
limit the management rights of the Surviving Corporation or CSI to assess
workforce needs and make appropriate adjustments as necessary or desirable
within their discretion subject to applicable laws and collective bargaining
agreements).

        10.6 DIVIDENDS. If the COMPANY is an S corporation, the COMPANY may pay
to each STOCKHOLDER as a dividend the full amount of his or her "accumulated
adjustments account" (as defined in Section 1368(e) of the Code) as of the
Balance Sheet Date, and may also pay to the STOCKHOLDERS as a dividend the full
amount of the COMPANY's earnings taxable to such STOCKHOLDERS for the period
after the Balance Sheet Date to the Funding and Consummation Date. If the
COMPANY is a C corporation, the COMPANY may pay to the STOCKHOLDERS as a
dividend the full amount of the COMPANY's earnings for the period after the
Balance Sheet Date to the Funding and Consummation Date. The COMPANY may borrow
funds to the extent necessary to make the payments contemplated by this Section
10.6 and to the extent necessary to ensure that the COMPANY has cash on hand to
adequately fund operations on the Funding and Consummation Date.

11.     INDEMNIFICATION

        The STOCKHOLDERS, CSI and NEWCO each make the following covenants that
are applicable to them, respectively:

of this Agreement until the Expiration Date, from and against all claims,
damages, actions, suits, proceedings, demands, assessments, adjustments, costs
and expenses (including specifically, but without limitation, reasonable

provided to CSI or its counsel by the COMPANY or the STOCKHOLDERS (but in the
case of the STOCKHOLDERS, only if such statement was provided in writing)
contained in the Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or arising out of or
based upon any omission or alleged omission to state therein a material fact
relating to the COMPANY or the STOCKHOLDERS required to be stated therein or
necessary to make the statements therein not misleading, provided, however, that
such indemnity shall not inure to the benefit of CSI, NEWCO, the COMPANY or the
Surviving Corporation to the extent that such untrue statement (or alleged
untrue statement) was made in, or omission (or alleged omission) occurred in,
any preliminary prospectus and the STOCKHOLDERS provided, in writing, corrected
information to CSI counsel and to CSI for inclusion in the final prospectus, and
such information was not so included or properly delivered, and provided
further, that no STOCKHOLDER shall be liable for any indemnification obligation
pursuant to this Section 11.1 to the extent attributable to a breach of any
representation, warranty or agreement made herein individually by any other
STOCKHOLDER.

        11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will

proceedings, demands, assessments, adjustments, costs and expenses (including
specifically, but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by the STOCKHOLDERS as a result of or arising from (i)

has claims against the STOCKHOLDERS by reason of such liabilities); or (iv) any
liability under the 1933 Act, the 1934 Act or other Federal or state law or
regulation, at common law or otherwise, arising out of or based upon any untrue
statement or alleged untrue statement of a material fact relating to CSI, NEWCO
or any of the Other Founding Companies contained in any preliminary prospectus,
the Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to CSI or
NEWCO or any of the Other Founding Companies required to be stated therein or
necessary to make the statements therein not misleading.

        11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a

defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying

                                      -56-

Party shall not settle any criminal proceeding without the written consent of
the Indemnified Party. If the Indemnifying Party undertakes to defend or settle,
it shall promptly notify the Indemnified Party of its intention to do so, and
the Indemnified Party shall cooperate with the Indemnifying Party and its
counsel in the defense thereof and in any settlement thereof. Such cooperation
shall include, but shall not be limited to, furnishing the Indemnifying Party
with any books, records or information reasonably requested by the Indemnifying
Party that are in the Indemnified Party's possession or control. All Indemnified
Parties shall use the same counsel, which shall be the counsel selected by
Indemnifying Party, provided that if counsel to the Indemnifying Party shall
have a conflict of interest that prevents counsel for the Indemnifying Party
from representing Indemnified Party, Indemnified Party shall have the right to
participate in such matter through counsel of its own choosing and Indemnifying
Party will reimburse the Indemnified Party for the reasonable expenses of its
counsel. After the Indemnifying Party has notified the Indemnified Party of its
intention to undertake to defend or settle any such asserted liability, and for
so long as the Indemnifying Party diligently pursues such defense, the
Indemnifying Party shall not be liable for any additional legal expenses
incurred by the Indemnified Party in connection with any defense or settlement
of such asserted liability, except (i) as set forth in the preceding sentence
and (ii) to the extent such participation is requested by the Indemnifying
Party, in which event the Indemnified Party shall be reimbursed by the
Indemnifying Party for reasonable additional legal expenses and out-of-pocket
expenses. If the Indemnifying Party desires to accept a final and complete
settlement of any such Third Person claim and the Indemnified Party refuses to
consent to such settlement, then the Indemnifying Party's liability under this
Section with respect to such Third Person claim shall be limited to the amount
so offered in settlement by said Third Person. Upon agreement as to such
settlement between said Third Person and the Indemnifying Party, the
Indemnifying Party shall, in exchange for a complete release from the
Indemnified Party, promptly pay to the Indemnified Party the amount agreed to in
such settlement and the Indemnified Party shall, from that moment on, bear full
responsibility for any additional costs of defense which it subsequently incurs
with respect to

                                      -57-

such claim and all additional costs of settlement or judgment. If the
Indemnifying Party does not undertake to defend such matter to which the
Indemnified Party is entitled to indemnification hereunder, or fails diligently
to pursue such defense, the Indemnified Party may undertake such defense through
counsel of its choice, at the cost and expense of the Indemnifying Party, and
the Indemnified Party may settle such matter, and the Indemnifying Party shall
reimburse the Indemnified Party for the amount paid in such settlement and any
other liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the Indemnified Party otherwise agrees in writing. The parties
hereto will make appropriate adjustments for insurance proceeds in determining
the amount of any indemnification obligation under this Section.

        11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section
11 shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

        11.5 LIMITATIONS ON INDEMNIFICATION. CSI, NEWCO, the Surviving
Corporation and the other persons or entities indemnified pursuant to Section
11.1 or 11.2 shall not assert any claim for indemnification hereunder against
the STOCKHOLDERS until such time as, and solely to the extent that, the
aggregate of all claims which such persons may have against such the
STOCKHOLDERS shall exceed the greater of (a) 1.0% of the sum of the cash paid to
STOCKHOLDERS plus the value of the CSI Stock delivered to STOCKHOLDERS
(calculated as provided in this Section 11.5) or (b) $50,000 (the
"Indemnification Threshold"). STOCKHOLDERS shall not assert any claim for
indemnification hereunder against CSI or NEWCO until such time as, and solely to
the extent that,

                                      -58-

the aggregate of all claims which STOCKHOLDERS may have against CSI or NEWCO
shall exceed $50,000.

        No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

        Notwithstanding any other term of this Agreement, no STOCKHOLDER shall
be liable under this Section 11 for an amount which exceeds the amount of
proceeds received by such STOCKHOLDER in connection with the Merger. For
purposes of calculating the value of the CSI Stock received by a STOCKHOLDER,
CSI Stock shall be valued at its initial public offering price as set forth in
the Registration Statement. It is hereby understood and agreed that a
STOCKHOLDER may satisfy an indemnification obligation through payment of a
combination of stock and cash in proportion equal to the proportion of stock and
cash received by such STOCKHOLDER in connection with the Merger, valued as
described immediately above.

12.     TERMINATION OF AGREEMENT

        12.1 TERMINATION. This Agreement may be terminated at any time prior to
the Funding and Consummation Date solely:

        (i) by mutual consent of the boards of directors of CSI and the COMPANY;

        (ii) by the STOCKHOLDERS or the COMPANY (acting through its board of
directors), on the one hand, or by CSI (acting through its board of directors),
on the other hand, if the transactions contemplated by this Agreement to take
place at the Closing shall not have been consummated by September 30, 1997,
unless the failure of such transactions to be consummated is due to the willful
failure of the party seeking to terminate this Agreement to perform any of its
obligations under this Agreement to the extent required to be performed by it
prior to or on the Funding and Consummation Date;

        (iii) by the STOCKHOLDERS or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due

                                      -59-

and timely performance of any of the covenants or agreements contained herein,
and the curing of such default shall not have been made on or before the Funding
and Consummation Date or by the STOCKHOLDERS or the COMPANY, if the conditions
set forth in Section 8 hereof have not been satisfied or waived as of the
Closing Date or the Funding and Consummation Date, as applicable, or by CSI, if
the conditions set forth in Section 9 hereof have not been satisfied or waived
as of the Closing Date or the Funding and Consummation Date, as applicable;

        (iv)   pursuant to Section 7.8 hereof; or

        (v)    pursuant to Section 4 hereof.

        12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.     NONCOMPETITION

        13.1 PROHIBITED ACTIVITIES. The STOCKHOLDERS will not, for a period of
five (5) years following the Funding and Consummation Date, for any reason
whatsoever, directly or indirectly, for themselves or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

        (i) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial capacity, whether as an employee, independent
contractor, consultant or advisor, or as a sales representative, in any heating,
ventilating or air conditioning services business in direct competition with CSI
or any of the subsidiaries thereof, within 100 miles of where the COMPANY or any
of its subsidiaries conducted business prior to the effectiveness of the Merger
(the "Territory");

                                      -60-

        (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the subsidiaries
thereof), provided that each STOCKHOLDER shall be permitted to call upon and
hire any member of his or her immediate family;

        (iii) call upon any person or entity which is, at that time, or which
has been, within one (1) year prior to the Funding and Consummation Date, a
customer of CSI (including the subsidiaries thereof), of the COMPANY or of any
of the Other Founding Companies within the Territory for the purpose of
soliciting or selling products or services in direct competition with CSI within
the Territory;

        (iv) call upon any prospective acquisition candidate, on any
STOCKHOLDER's own behalf or on behalf of any competitor in the heating,
ventilation or air conditioning services business, which candidate, to the
actual knowledge of such STOCKHOLDER after due inquiry, was called upon by CSI
(including the subsidiaries thereof) or for which, to the actual knowledge of
such STOCKHOLDER after due inquiry, CSI (or any subsidiary thereof) made an
acquisition analysis, for the purpose of acquiring such entity; or

        (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

        Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

        13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that

                                      -61-

could be caused to CSI for which it would have no other adequate remedy, each
STOCKHOLDER agrees that the foregoing covenant may be enforced by CSI in the
event of breach by such STOCKHOLDER, by injunctions and restraining orders.

        13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDERS in light of the activities and business of CSI (including the
subsidiaries thereof) on the date of the execution of this Agreement and the
current plans of CSI.

        13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

        13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of each STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which such
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

        13.6 MATERIALITY. The COMPANY and the STOCKHOLDERS hereby agree that
this covenant is a material and substantial part of this transaction.

                                      -62-

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

        14.1 STOCKHOLDERS. The STOCKHOLDERS recognize and acknowledge that they
had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. The STOCKHOLDERS agree that they
will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except (a) to authorized representatives of CSI, (b) following the Closing, such
information may be disclosed by the STOCKHOLDERS as is required in the course of
performing their duties for CSI or the Surviving Corporation and (c) to counsel
and other advisers, provided that such advisers (other than counsel) agree to
the confidentiality provisions of this Section 14.1, unless (i) such information
becomes known to the public generally through no fault of the STOCKHOLDERS, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), the STOCKHOLDERS shall, if possible, give prior written notice
thereof to CSI and provide CSI with the opportunity to contest such disclosure,
or (iii) the disclosing party reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party. In the event of a breach or threatened breach by any of the STOCKHOLDERS
of the provisions of this Section, CSI shall be entitled to an injunction
restraining such STOCKHOLDERS from disclosing, in whole or in part, such
confidential information. Nothing herein shall be construed as prohibiting CSI
from pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. In the event the transactions contemplated by
this Agreement are not consummated, STOCKHOLDERS shall have none of the
above-mentioned restrictions on their ability to disseminate confidential
information with respect to the COMPANY.

                                      -63-

        14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they
had in the past and currently have access to certain confidential information of
the COMPANY, such as operational policies, and pricing and cost policies that
are valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, (c) to the Other Founding Companies and their representatives pursuant to
Section 7.1(a), unless (i) such information becomes known to the public
generally through no fault of CSI or NEWCO, (ii) disclosure is required by law
or the order of any governmental authority under color of law, provided, that
prior to disclosing any information pursuant to this clause (ii), CSI and NEWCO
shall, if possible, give prior written notice thereof to the COMPANY and the
STOCKHOLDERS and provide the COMPANY and the STOCKHOLDERS with the opportunity
to contest such disclosure, or (iii) the disclosing party reasonably believes
that such disclosure is required in connection with the defense of a lawsuit
against the disclosing party, and (d) to the public to the extent necessary or
advisable in connection with the filing of the Registration Statement and the
IPO and the securities laws applicable thereto and to the operation of CSI as a
publicly held entity after the IPO. In the event of a breach or threatened
breach by CSI or NEWCO of the provisions of this Section, the COMPANY and the
STOCKHOLDERS shall be entitled to an injunction restraining CSI and NEWCO from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting the COMPANY and the STOCKHOLDERS from pursuing
any other available remedy for such breach or threatened breach, including the
recovery of damages.

        14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and

                                      -64-

irreparable damage that would be caused for which they would have no other
adequate remedy, the parties hereto agree that, in the event of a breach by any
of them of the foregoing covenants, the covenant may be enforced against the
other parties by injunctions and restraining orders.

        14.4 SURVIVAL. The obligations of the parties under this Article 14
shall survive the termination of this Agreement for a period of five years from
the Funding and Consummation Date.

15.     TRANSFER RESTRICTIONS

        15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDERS or family members, the trustees
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the STOCKHOLDERS shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of CSI Stock as described in Section 3.1 received by the STOCKHOLDERS in
the Merger. The certificates evidencing the CSI Stock delivered to the
STOCKHOLDERS pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as CSI may deem necessary or appropriate: THE SHARES REPRESENTED BY THIS
CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED,
PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL
NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE,
TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION
PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE WRITTEN REQUEST OF THE
HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND

                                      -65-

(AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED
ABOVE.

16.     FEDERAL SECURITIES ACT REPRESENTATIONS

        16.1 COMPLIANCE WITH LAW. The STOCKHOLDERS acknowledge that the shares
of CSI Stock to be delivered to the STOCKHOLDERS pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and may not be resold without compliance with the Act. The CSI Stock
to be acquired by such STOCKHOLDERS pursuant to this Agreement is being acquired
solely for their own respective accounts, for investment purposes only, and with
no present intention of distributing, selling or otherwise disposing of it in
connection with a distribution. The STOCKHOLDERS covenant, warrant and represent
that none of the shares of CSI Stock issued to such STOCKHOLDERS will be
offered, sold, assigned, pledged, hypothecated, transferred or otherwise
disposed of except after full compliance with all of the applicable provisions
of the Act and the rules and regulations of the SEC. All the CSI Stock shall
bear the following legend in addition to the legend required under Section 15 of
this Agreement: THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED
IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

        16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDERS are able to bear
the economic risk of an investment in the CSI Stock to be acquired pursuant to
this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment in the
CSI Stock. The STOCKHOLDERS party hereto have had an adequate opportunity

                                      -66-

to ask questions and receive answers from the officers of CSI concerning any and
all matters relating to the transactions described herein including, without
limitation, the background and experience of the current and proposed officers
and directors of CSI, the plans for the operations of the business of CSI, the
business, operations and financial condition of the Founding Companies other
than the COMPANY, and any plans for additional acquisitions and the like. The
STOCKHOLDERS have asked any and all questions in the nature described in the
preceding sentence and all questions have been answered to their satisfaction.

17.     REGISTRATION RIGHTS

        17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
each of the STOCKHOLDERS prompt written notice of its intent to do so. Upon the
written request of any of the STOCKHOLDERS given within 30 days after receipt of
such notice, CSI shall cause to be included in such registration all of the CSI
Stock issued to the STOCKHOLDERS pursuant to this Agreement (including any stock
issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) which any such STOCKHOLDER requests, provided that CSI shall
have the right to reduce the number of shares included in such registration to
the extent that inclusion of such shares could, in the opinion of tax counsel to
CSI or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Registration Statement as a tax-free
organization. In addition, if CSI is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1 that the number
of shares to be sold by persons other than CSI is greater than the number of
such

                                      -67-

shares which can be offered without adversely affecting the offering, CSI may
reduce pro rata the number of shares offered for the accounts of such persons
(based upon the number of shares held by such person) to a number deemed
satisfactory by such managing underwriter, provided, that, for each such
offering made by CSI after the IPO, such reduction shall be made first by
reducing the number of shares to be sold by persons other than CSI, the
STOCKHOLDERS and the stockholders of the Other Founding Companies (collectively,
the STOCKHOLDERS and the stockholders of the other Founding Companies being
referred to herein as the "Founding Stockholders"), and thereafter, if a further
reduction is required, by reducing the number of shares to be sold by the
Founding Stockholders.

        17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year
after the Closing and prior to the date three years after the Closing, the
holders of a majority of the shares of CSI Stock issued to the Founding
Stockholders pursuant to this Agreement and the Other Agreements which have not
been previously registered or sold and which are not entitled to be sold under
Rule 144(k) (or any similar or successor provision) promulgated under the 1933
Act may request in writing that CSI file a registration statement under the 1933
Act covering the registration of the shares of CSI Stock issued to the
STOCKHOLDERS pursuant to this Agreement and the Other Agreements (including any
stock issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) then held by such Founding Stockholders (a "Demand
Registration"). Within ten (10) days of the receipt of such request, CSI shall
give written notice of such request to all other Founding Stockholders and
shall, as soon as practicable but in no event later than 45 days after notice
from any STOCKHOLDER, file and use its best efforts to cause to become effective
a registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

                                      -68-

        Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the date on which CSI
would otherwise be required to make such filing pursuant to the foregoing
paragraph.

        If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective date of such registration unless CSI is no longer proceeding
diligently to effect such registration; provided that CSI shall provide the
Founding Stockholders the right to participate in such public offering pursuant
to, and subject to, Section 17.1 hereof.

        17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with
the registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

        17.4 UNDERWRITING AGREEMENT. In connection with each registration
pursuant to Sections 17.1 and 17.2 covering an underwritten registered offering,
CSI and each participating holder agree

                                      -69-

to enter into a written agreement with the managing underwriters in such form
and containing such provisions as are customary in the securities business for
such an arrangement between such managing underwriters and companies of CSI's
size and investment stature, including indemnification.

        17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by any STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to such STOCKHOLDER.

        17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

               (i) make and keep public information regarding CSI available as
        those terms are understood and defined in Rule 144 under the 1933 Act
        for a period of four years beginning 90 days following the effective
        date of the Registration Statement;

               (ii) file with the SEC in a timely manner all reports and other
        documents required of CSI under the 1933 Act and the 1934 Act at any
        time after it has become subject to such reporting requirements; and

               (iii) so long as a STOCKHOLDER owns any restricted CSI Common
        Stock, furnish to each STOCKHOLDER forthwith upon written request a
        written statement by CSI as to its compliance with the reporting
        requirements of Rule 144 (at any time from and after 90 days following
        the effective date of the Registration Statement, and of the 1933 Act
        and the 1934 Act (at any time after it has become subject to such
        reporting requirements), a copy of the most recent annual or quarterly
        report of CSI, and such other reports and documents so filed as a
        STOCKHOLDER may reasonably request in availing itself of any rule or
        regulation of the SEC allowing a STOCKHOLDER to sell any such shares
        without registration.

                                      -70-

        18.    GENERAL

        18.1 COOPERATION. The COMPANY, STOCKHOLDERS, CSI and NEWCO shall each

contribute to any plan program, fund or arrangement that constitutes an
"employee pension benefit plan," nor has COMPANY or any Subsidiary any
obligation to contribute to or accrue or pay any benefits under any deferred
compensation or retirement funding arrangement on behalf of any employee or
employees (such as, for example, and without limitation, any individual
retirement account or annuity, any "excess benefit plan" (within the meaning of
Section 3(36) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) or any non-qualified deferred compensation arrangement). For the
purposes of this Agreement, the term "employee pension benefit plan" shall have

pension benefit plan other than the plans set forth on Schedule 5.19, nor is
COMPANY or any Subsidiary required to contribute to any retirement plan pursuant

        Neither the COMPANY nor any Subsidiary is now, or can as a result of its
past activities become, liable to the Pension Benefit Guaranty Corporation or to
any multiemployer employee pension benefit plan under the provisions of Title IV
of ERISA.

regulations.

respect to any plan listed on Schedule 5.19 have either been fulfilled in their
entirety or are fully reflected on the balance sheet of the COMPANY as of the
Balance Sheet Date.

        5.20 COMPLIANCE WITH ERISA. All such plans listed on Schedule 5.19 that

Service to be so qualified, and copies of such determination letters are
included as part of Schedule 5.19 hereof. Except as disclosed on Schedule 5.20,

deficiency, as defined in Section 412(a) of the Code and Section 302(1) of
ERISA; and COMPANY (including the COMPANY's Subsidiaries) has not incurred any
liability for excise tax or penalty due to the Internal Revenue Service nor any
liability to the Pension Benefit Guaranty Corporation. The STOCKHOLDERS further

                                      -23-


               (ii) no such plan listed in Schedule 5.19 subject to the
        provisions of Title IV of ERISA has been terminated;

               (iii) there have been no "reportable events" (as that phrase is
        defined in Section 4043 of ERISA) with respect to any such plan listed
        in Schedule 5.19;

               (iv) COMPANY (including the COMPANY's Subsidiaries) has not
        incurred liability under Section 4062 of ERISA; and

               (v) No circumstances exist pursuant to which the COMPANY could
        have any direct or indirect liability whatsoever (including, but not
        limited to, any liability to any multiemployer plan or the PBGC under
        Title IV of ERISA or to the Internal Revenue Service for any excise tax
        or penalty, or being subject to any statutory lien to secure payment of
        any such liability) with respect to any plan now or heretofore
        maintained or contributed to by any entity other than the COMPANY that
        is, or at any time was, a member of a "controlled group" (as defined in
        Section 412(n)(6)(B) of the Code) that includes the COMPANY. 5.21

any failure of the Registration Statement to become

                                      -29-


effective, the IPO to occur at a particular price or within a particular range
of prices or to occur at all; and (iii) that the decision of STOCKHOLDERS to
enter into this Agreement, or to vote in favor of or consent to the proposed

amendment or supplement; and provided further, that no amendment or supplement

supplement, which consent shall have been deemed given by CSI or any Founding
Company if no response is received within 24 hours following receipt of notice
of such amendment or supplement (or sooner if required by the circumstances
under which such consent is requested), but the COMPANY does not give its
consent (provided that consent shall be deemed given if any COMPANY consents),
the COMPANY may terminate this Agreement pursuant to Section 12.1(iv) hereof. In
the event that any COMPANY seeks to amend or supplement a Schedule pursuant to
this Section 7.8, and CSI and a majority of the Other Founding Companies do not

terminated by mutual consent as set forth in Section 12.1(i) hereof. In the
event that CSI or any NEWCO seeks to amend or supplement a Schedule pursuant to
this Section 7.8 and a majority of the Founding Companies do not consent to such
amendment or supplement, this Agreement shall be deemed terminated by mutual
consent as set forth in Section 12.1(i) hereof. No party to this Agreement shall
be liable to any other party if this Agreement shall be terminated pursuant to

Securities Act, any information contained in the prospectus concerning such
COMPANY or the STOCKHOLDERS becomes incorrect or incomplete in any material
respect, and to provide the information needed to correct such inaccuracy.

herself, that the Registration Statement will not include an untrue statement of

statement of income, cash flows and retained earnings of such COMPANY for all
fiscal quarters ended after the Balance Sheet Date, disclosing no material
adverse change in the financial condition of such COMPANY or the results of its
operations from the financial statements as of the Balance Sheet Date. Such
financial statements shall have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis throughout the
periods indicated (except as noted therein). Except as noted in such financial
statements, all of such financial statements will present fairly the results of

filings under the Hart-Scott Act are required, then: (i) each of the parties
hereto agrees to cooperate and use its best efforts to comply with the
Hart-Scott Act, (ii) such compliance by the STOCKHOLDERS and each COMPANY shall

               (b) the entering into of financial arrangements for the benefit
        of the STOCKHOLDERS.

        10.3   PREPARATION AND FILING OF TAX RETURNS.

               (i) The COMPANY shall, if possible, file or cause to be filed all
        separate Returns of any Acquired Party for all taxable periods that end
        on or before the Funding and Consummation Date. Notwithstanding the
        foregoing, the STOCKHOLDERS shall file or cause to be filed all separate
        federal income Tax Returns of any Acquired Party for all taxable periods
        that end on or before the Funding and Consummation Date. The
        STOCKHOLDERS shall pay or cause to be paid all Tax liabilities (in
        excess of all amounts already paid with respect thereto or properly
        accrued or reserved with respect thereto on the COMPANY Financial
        Statements) shown by such Returns to be due.

               (ii) CSI shall file or cause to be filed all separate Returns of,

        cooperation and information as any of them reasonably may request in
        filing any Return, amended Return or claim for refund, determining a

        audit or other proceeding in respect of Taxes. Such cooperation and
        information shall include providing copies of all relevant portions of
        relevant Returns, together with relevant accompanying schedules and
        relevant work papers, relevant documents relating to rulings

                                      -53-


        or other determinations by Taxing Authorities and relevant records
        concerning the ownership and Tax basis of property, which such party may
        possess. Each party shall make its employees reasonably available on a
        mutually convenient basis at its cost to provide explanation of any
        documents or information so provided. Subject to the preceding sentence,
        each party required to file Returns pursuant to this Agreement shall
        bear all costs of filing such Returns.

        10.4 DIRECTORS. The persons named in the draft of the Registration
Statement shall beappointed as directors and elected as officers of CSI, as and

        10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation to provide
replacement plans that have the same terms and provisions as the existing plans,
provided, further, that any new health insurance plan shall provide for coverage
for preexisting conditions. On the Funding and Consummation Date, the employees
of each COMPANY will be the employees of the respective Surviving Corporation
(provided that this provision is for purposes of clarifying that the Merger, in
and of itself, will not have any impact on the employment status of any employee
and provided, further that this provision shall not in any way limit the
management rights of such Surviving Corporation or CSI to assess workforce needs
and make appropriate adjustments as

                                      -54-

covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless CSI, NEWCO, the COMPANY and the Surviving Corporation
at all times, from and after the date of this Agreement until the Expiration
Date, from and against all claims, damages, actions, suits, proceedings,

but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by CSI, NEWCO, the COMPANY or the Surviving Corporation
as a result of or arising from (i) any breach of the representations and
warranties of the STOCKHOLDERS or either COMPANY set forth herein or on the
schedules or certificates delivered in connection herewith, (ii) any breach of
any agreement on the part of the STOCKHOLDERS or either COMPANY under this
Agreement, or (iii) any liability under the 1933 Act, the 1934 Act or other
Federal or state law or regulation, at common law or otherwise, arising out of
or based upon any untrue statement or alleged untrue statement of a material
fact relating to either COMPANY or the STOCKHOLDERS, and provided to CSI or its
counsel by either COMPANY or the STOCKHOLDERS (but in the case of the
STOCKHOLDERS, only if such statement was provided in writing) contained in the
Registration Statement or any

                                      -55-


prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or arising out of or based upon any omission or alleged omission to
state therein a material fact relating to either COMPANY or the STOCKHOLDERS
required to be stated therein or necessary to make the statements therein not
misleading, provided, however, that such indemnity shall not inure to the
benefit of CSI, NEWCO, the COMPANY or the Surviving Corporation to the extent
that such untrue statement (or alleged untrue statement) was made in, or
omission (or alleged omission) occurred in, any preliminary prospectus and the
STOCKHOLDERS provided, in writing, corrected information to CSI counsel and to
CSI for inclusion in the final prospectus, and such information was not so
included or properly delivered, and provided further, that no STOCKHOLDER shall
be liable for any indemnification obligation pursuant to this Section 11.1 to
the extent attributable to a breach of any representation, warranty or agreement
made herein individually by any other STOCKHOLDER.

        11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDERS at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
STOCKHOLDERS as a result of or arising from (i) any breach by CSI or NEWCO of
their representations and warranties set forth herein or on the schedules or
certificates attached hereto, (ii) any nonfulfillment of any agreement on the
part of CSI or NEWCO under this Agreement, (iii) any liabilities which the
STOCKHOLDERS may incur due to CSI's or NEWCO's failure to be responsible for the
liabilities and obligations of the COMPANY as provided in Section 1 hereof
(except to the extent that CSI or NEWCO has claims against the STOCKHOLDERS by
reason of such liabilities); or (iv) any liability under the 1933 Act, the 1934
Act or other Federal or state law or regulation, at common law or otherwise,
arising out of or based upon any untrue statement or alleged untrue statement of
a material fact relating to CSI, NEWCO or any of the Other Founding Companies
contained in any preliminary prospectus, the Registration Statement or any
prospectus

                                      -56-


forming a part thereof, or any amendment thereof or supplement thereto, or
arising out of or based upon any omission or alleged omission to state therein a
material fact relating to CSI or NEWCO or any of the Other Founding Companies
required to be stated therein or necessary to make the statements therein not
misleading.

        11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified Party
of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or control. All Indemnified Parties shall use the same counsel, which
shall be the counsel selected by Indemnifying Party, provided that if counsel to
the Indemnifying Party shall have a conflict of interest that prevents counsel
for the Indemnifying Party from representing Indemnified Party, Indemnified
Party shall have the right to participate in such matter through counsel of its
own choosing and Indemnifying Party will reimburse the Indemnified Party for the
reasonable expenses of its counsel. After the Indemnifying Party has notified
the Indemnified Party of its intention to

                                      -57-


undertake to defend or settle any such asserted liability, and for so long as
the Indemnifying Party diligently pursues such defense, the Indemnifying Party
shall not be liable for any additional legal expenses incurred by the
Indemnified Party in connection with any defense or settlement of such asserted
liability, except (i) as set forth in the preceding sentence and (ii) to the
extent such participation is requested by the Indemnifying Party, in which event
the Indemnified Party shall be reimbursed by the Indemnifying Party for
reasonable additional legal expenses and out-of-pocket expenses. If the
Indemnifying Party desires to accept a final and complete settlement of any such
Third Person claim and the Indemnified Party refuses to consent to such
settlement, then the Indemnifying Party's liability under this Section with
respect to such Third Person claim shall be limited to the amount so offered in
settlement by said Third Person. Upon agreement as to such settlement between
said Third Person and the Indemnifying Party, the Indemnifying Party shall, in
exchange for a complete release from the Indemnified Party, promptly pay to the
Indemnified Party the amount agreed to in such settlement and the Indemnified
Party shall, from that moment on, bear full responsibility for any additional
costs of defense which it subsequently incurs with respect to such claim and all
additional costs of settlement or judgment. If the Indemnifying Party does not
undertake to defend such matter to which the Indemnified Party is entitled to
indemnification hereunder, or fails diligently to pursue such defense, the
Indemnified Party may undertake such defense through counsel of its choice, at
the cost and expense of the Indemnifying Party, and the Indemnified Party may
settle such matter, and the Indemnifying Party shall reimburse the Indemnified
Party for the amount paid in such settlement and any other liabilities or
expenses incurred by the Indemnified Party in connection therewith, provided,
however, that under no circumstances shall the Indemnified Party settle any
Third Person claim without the written consent of the Indemnifying Party, which
consent shall not be unreasonably withheld or delayed. All settlements hereunder
shall effect a complete release of the Indemnified Party, unless the Indemnified
Party otherwise agrees in writing. The parties hereto will make appropriate
adjustments

                                      -58-


for insurance proceeds in determining the amount of any indemnification
obligation under this Section.

        11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section
11 shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

        11.5 LIMITATIONS ON INDEMNIFICATION. None of CSI, any NEWCO, any
Surviving Corporation nor any other persons or entities indemnified pursuant to
Section 11.1 or 11.2 shall assert any claim for indemnification hereunder
against the STOCKHOLDERS until such time as, and solely to the extent that, the
aggregate of all claims which such persons may have against such the
STOCKHOLDERS shall exceed the greater of (a) 1.0% of the sum of the cash paid to
STOCKHOLDERS plus the value of the CSI Stock delivered to STOCKHOLDERS
(calculated as provided in this Section 11.5) or (b) $50,000 (the
"Indemnification Threshold"). STOCKHOLDERS shall not assert any claim for
indemnification hereunder against CSI or any NEWCO until such time as, and
solely to the extent that, the aggregate of all claims which STOCKHOLDERS may
have against CSI or any or all NEWCOs shall exceed $50,000.

        No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

        Notwithstanding any other term of this Agreement, no STOCKHOLDER shall
be liable under this Section 11 for an amount which exceeds the amount of
proceeds received by such STOCKHOLDER in connection with the Merger. For
purposes of calculating the value of the CSI Stock received by a STOCKHOLDER,
CSI Stock shall be valued at its initial public offering price as set forth in
the Registration Statement. It is hereby understood and agreed that a
STOCKHOLDER may satisfy an indemnification obligation through payment of a
combination of

                                      -59-


stock and cash in proportion equal to the proportion of stock and cash received
by such STOCKHOLDER in connection with the Merger, valued as described
immediately above.

12.     TERMINATION OF AGREEMENT

        12.1 TERMINATION. This Agreement may be terminated (it being understood
and agreed that, for purposes of this Section 12, the term "COMPANY" means both

        (ii) by the STOCKHOLDERS or the COMPANY (acting through its board of
directors), on the one hand, or by CSI (acting through its board of directors),
on the other hand, if the transactions contemplated by this Agreement to take
place at the Closing shall not have been consummated by September 30, 1997,
unless the failure of such transactions to be consummated is due to the willful
failure of the party seeking to terminate this Agreement to perform any of its
obligations under this Agreement to the extent required to be performed by it
prior to or on the Funding and Consummation Date;

        (iii) by the STOCKHOLDERS or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due and timely performance of any of the covenants or
agreements contained herein, and the curing of such default shall not have been
made on or before the Funding and Consummation Date or by the STOCKHOLDERS, or
the COMPANY, if the conditions set forth in Section 8 hereof have not been
satisfied or waived as of the Closing Date or the Funding and Consummation Date,
as applicable, or by CSI, if the conditions set forth in Section 9 hereof have
not been satisfied or waived as of the Closing Date or the Funding and
Consummation Date, as applicable;

        (iv)   pursuant to Section 7.8 hereof; or

        (v)    pursuant to Section 4 hereof.

                                      -60-


        12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

                                      -61-


purpose of soliciting or selling products or services in direct competition with
CSI within the Territory;

        (iv) call upon any prospective acquisition candidate, on any
STOCKHOLDER'S own behalf or on behalf of any competitor in the heating,
ventilation or air conditioning services business, which candidate, to the
actual knowledge of such STOCKHOLDER after due inquiry, was called upon by CSI
(including the subsidiaries thereof) or for which, to the actual knowledge of
such STOCKHOLDER after due inquiry, CSI (or any subsidiary thereof) made an
acquisition analysis, for the purpose of acquiring such entity; or

        (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

        Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

        13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to CSI for which it would
have no other adequate remedy, each STOCKHOLDER agrees that the foregoing
covenant may be enforced by CSI in the event of breach by such STOCKHOLDER, by
injunctions and restraining orders.

        13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDERS in light of the activities and business of CSI (including the
subsidiaries thereof) on the date of the execution of this Agreement and the
current plans of CSI.

                                      -62-


        13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

        13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of each STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which such
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

        13.6 MATERIALITY. The COMPANY and the STOCKHOLDERS hereby agree that
this covenant is a material and substantial part of this transaction.

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

        14.1 STOCKHOLDERS. Each STOCKHOLDER recognizes and acknowledges that he
had in the past, currently has, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. Each

                                      -63-


STOCKHOLDER agrees that he will not disclose such confidential information to
any person, firm, corporation, association or other entity for any purpose or
reason whatsoever, except (a) to authorized representatives of CSI, (b)
following the Closing, such information may be disclosed by the STOCKHOLDER as
is required in the course of performing his duties for CSI or the Surviving
Corporation and (c) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, unless (i) such information becomes known to the public generally through
no fault of the STOCKHOLDER, (ii) disclosure is required by law or the order of
any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii), the STOCKHOLDER shall,
if possible, give prior written notice thereof to CSI and provide CSI with the
opportunity to contest such disclosure, or (iii) the disclosing party reasonably
believes that such disclosure is required in connection with the defense of a
lawsuit against the disclosing party. In the event of a breach or threatened
breach by the any STOCKHOLDER of the provisions of this Section, CSI shall be
entitled to an injunction restraining such STOCKHOLDER from disclosing, in whole
or in part, such confidential information. Nothing herein shall be construed as
prohibiting CSI from pursuing any other available remedy for such breach or
threatened breach, including the recovery of damages. In the event the
transactions contemplated by this Agreement are not consummated, STOCKHOLDERS
shall have none of the above-mentioned restrictions on their ability to
disseminate confidential information with respect to the COMPANY.

        14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they
had in the past and currently have access to certain confidential information of
the COMPANY, such as operational policies, and pricing and cost policies that
are valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other

                                      -64-


advisers, provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 14.1, (c) to the Other Founding
Companies and their representatives pursuant to Section 7.1(a), unless (i) such
information becomes known to the public generally through no fault of CSI or
NEWCO, (ii) disclosure is required by law or the order of any governmental
authority under color of law, provided, that prior to disclosing any information
pursuant to this clause (ii), CSI and NEWCO shall, if possible, give prior
written notice thereof to the COMPANY and the STOCKHOLDERS and provide the
COMPANY and the STOCKHOLDERS with the opportunity to contest such disclosure, or
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, and
(d) to the public to the extent necessary or advisable in connection with the
filing of the Registration Statement and the IPO and the securities laws
applicable thereto and to the operation of CSI as a publicly held entity after
the IPO. In the event of a breach or threatened breach by CSI or NEWCO of the
provisions of this Section, the COMPANY and the STOCKHOLDERS shall be entitled
to an injunction restraining CSI and NEWCO from disclosing, in whole or in part,
such confidential information. Nothing herein shall be construed as prohibiting
the COMPANY and the STOCKHOLDERS from pursuing any other available remedy for
such breach or threatened breach, including the recovery of damages.

        14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

        14.4 SURVIVAL. The obligations of the parties under this Article 14
shall survive the termination of this Agreement for a period of five years from
the Funding and Consummation Date.

15.     TRANSFER RESTRICTIONS

                                      -65-


        15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDERS or family members, the trustees
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, the STOCKHOLDERS shall not sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of CSI Stock as described in Section 3.1 received by the STOCKHOLDERS in
the Merger. The certificates evidencing the CSI Stock delivered to the
STOCKHOLDERS pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as CSI may deem necessary or appropriate: THE SHARES REPRESENTED BY THIS
CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED,
PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL
NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE,
TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION
PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE WRITTEN REQUEST OF THE
HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND
(AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED
ABOVE.

16.     FEDERAL SECURITIES ACT REPRESENTATIONS

        16.1 COMPLIANCE WITH LAW. The STOCKHOLDERS acknowledge that the shares
of CSI Stock to be delivered to the STOCKHOLDERS pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and may not be resold without compliance with the Act. The CSI Stock
to be acquired by the STOCKHOLDERS pursuant to this Agreement is being acquired
solely for their own accounts, for investment purposes only, and with no present
intention of distributing, selling or otherwise disposing of it in connection
with a

                                      -66-


distribution. Each STOCKHOLDER covenants, warrants and represents that none of
the shares of CSI Stock issued to such STOCKHOLDER will be offered, sold,
assigned, pledged, hypothecated, transferred or otherwise disposed of except
after full compliance with all of the applicable provisions of the Act and the
rules and regulations of the SEC. All the CSI Stock shall bear the following
legend in addition to the legend required under Section 15 of this Agreement:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

        16.2 ECONOMIC RISK; SOPHISTICATION. Each STOCKHOLDER is able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and has such
knowledge and experience in financial and business matters that he is capable of
evaluating the merits and risks of the proposed investment in the CSI Stock.
Each STOCKHOLDER has had an adequate opportunity to ask questions and receive
answers from the officers of CSI concerning any and all matters relating to the
transactions described herein including, without limitation, the background and
experience of the current and proposed officers and directors of CSI, the plans
for the operations of the business of CSI, the business, operations and
financial condition of the Founding Companies other than the COMPANY, and any
plans for additional acquisitions and the like. Each STOCKHOLDER has asked any
and all questions in the nature described in the preceding sentence and all
questions have been answered to his satisfaction.

                                      -67-


17.     REGISTRATION RIGHTS

        17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
the STOCKHOLDERS prompt written notice of its intent to do so. Upon the written
request of any STOCKHOLDER given within 30 days after receipt of such notice,
CSI shall cause to be included in such registration all of the CSI Stock issued
to such STOCKHOLDER pursuant to this Agreement (including any stock issued as
(or issuable upon the conversion or exchange of any convertible security,
warrant, right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) which the STOCKHOLDER requests, provided that CSI shall have the right to
reduce the number of shares included in such registration to the extent that
inclusion of such shares could, in the opinion of tax counsel to CSI or its
independent auditors, jeopardize the status of the transactions contemplated
hereby and by the Registration Statement as a tax-free organization. In
addition, if CSI is advised in writing in good faith by any managing underwriter
of an underwritten offering of the securities being offered pursuant to any
registration statement under this Section 17.1 that the number of shares to be
sold by persons other than CSI is greater than the number of such shares which
can be offered without adversely affecting the offering, CSI may reduce pro rata
the number of shares offered for the accounts of such persons (based upon the
number of shares held by such person) to a number deemed satisfactory by such
managing underwriter, provided, that, for each such offering made by CSI after
the IPO, such reduction shall be made first by reducing the number of shares to
be sold by persons other than CSI, the STOCKHOLDERS and the stockholders of the
Other Founding Companies (collectively, the STOCKHOLDERS and the stockholders of
the other Founding Companies being referred to herein as the "Founding
Stockholders"), and thereafter, if a further reduction is required, by reducing
the number of shares to be sold by the Founding Stockholders.

                                      -68-


        17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year
after the Closing and prior to the date three years after the Closing, the
holders of a majority of the shares of CSI Stock issued to the Founding
Stockholders pursuant to this Agreement and the Other Agreements which have not
been previously registered or sold and which are not entitled to be sold under
Rule 144(k) (or any similar or successor provision) promulgated under the 1933
Act may request in writing that CSI file a registration statement under the 1933
Act covering the registration of the shares of CSI Stock issued to the
STOCKHOLDERS pursuant to this Agreement and the Other Agreements (including any
stock issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) then held by such Founding Stockholders (a "Demand
Registration"). Within ten (10) days of the receipt of such request, CSI shall
give written notice of such request to all other Founding Stockholders and
shall, as soon as practicable but in no event later than 45 days after notice
from any STOCKHOLDER, file and use its best efforts to cause to become effective
a registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

        Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the date on which CSI
would otherwise be required to make such filing pursuant to the foregoing
paragraph.

        If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective

                                      -69-

date of such registration unless CSI is no longer proceeding diligently to
effect such registration; provided that CSI shall provide the Founding
Stockholders the right to participate in such public offering pursuant to, and
subject to, Section 17.1 hereof.

        17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with
the registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

        17.4 UNDERWRITING AGREEMENT. In connection with each registration
pursuant to Sections 17.1 and 17.2 covering an underwritten registered offering,
CSI and each participating holder agree to enter into a written agreement with
the managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
managing underwriters and companies of CSI's size and investment stature,
including indemnification.

        17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by any STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to such STOCKHOLDER.

                                      -70-


        17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

               (i) make and keep public information regarding CSI available as
        those terms are understood and defined in Rule 144 under the 1933 Act
        for a period of four years beginning 90 days following the effective
        date of the Registration Statement;

               (ii) file with the SEC in a timely manner all reports and other
        documents required of CSI under the 1933 Act and the 1934 Act at any
        time after it has become subject to such reporting requirements; and

               (iii) so long as a STOCKHOLDER owns any restricted CSI Common
        Stock, furnish to each STOCKHOLDER forthwith upon written request a
        written statement by CSI as to its compliance with the reporting
        requirements of Rule 144 (at any time from and after 90 days following
        the effective date of the Registration Statement, and of the 1933 Act
        and the 1934 Act (at any time after it has become subject to such
        reporting requirements), a copy of the most recent annual or quarterly
        report of CSI, and such other reports and documents so filed as a
        STOCKHOLDER may reasonably request in availing itself of any rule or
        regulation of the SEC allowing a STOCKHOLDER to sell any such shares
        without registration.

        18.    GENERAL

        18.1 COOPERATION. The COMPANY, STOCKHOLDERS, CSI and NEWCO shall each
deliver or cause to be delivered to the other on the Funding and Consummation
Date, and at such other times and places as shall be reasonably agreed to, such
additional instruments as the other may reasonably request for the purpose of
carrying out this Agreement. Each COMPANY will cooperate and use its reasonable
efforts to have the present officers, directors and employees of such COMPANY
cooperate with CSI on and after the Funding and Consummation Date in furnishing

                                      -71-

        18.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the

successors of CSI, and the heirs and legal representatives of the STOCKHOLDERS.

        18.3 ENTIRE AGREEMENT. This Agreement (including the schedules, exhibits
and annexes attached hereto) and the documents delivered pursuant hereto
constitute the entire agreement and understanding among the STOCKHOLDERS, each
COMPANY, each NEWCO and CSI and supersede any prior agreement and understanding
relating to the subject matter of this Agreement. This Agreement, upon

enforceable in accordance with its terms and may be modified or amended only by
a written instrument executed by the STOCKHOLDERS, each COMPANY, each NEWCO and
CSI, acting through their respective officers or trustees, duly authorized by
their respective Boards of Directors. Any disclosure made on any Schedule
delivered pursuant hereto shall be deemed to have been disclosed for purposes of
any other Schedule required hereby, provided that each COMPANY shall make a good
faith effort to cross reference disclosure, as necessary or advisable, between
related Schedules.

        18.4 COUNTERPARTS. This Agreement may be executed simultaneously in two
(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

        18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each
party represents and warrants that it employed no broker or agent in connection
with this transaction and agrees to indemnify the other parties hereto against
all loss, cost, damages or expense arising out of claims for

                                      -72-


fees or commission of brokers employed or alleged to have been employed by such
indemnifying party.

        18.6 EXPENSES. Whether or not the transactions herein contemplated shall

be performed by CSI under this Agreement, including the fees and expenses of
Arthur Andersen LLP, Bracewell & Patterson, L.L.P., and any other person or

preparing the Registration Statement. Each STOCKHOLDER shall pay all sales, use,
transfer, real property transfer, recording, gains, stock transfer and other
similar taxes and fees ("Transfer Taxes") imposed in connection with the Merger,
other than Transfer Taxes, if any, imposed by the State of Delaware. Each
STOCKHOLDER shall file all necessary documentation and Returns with respect to
such Transfer Taxes. In addition, each STOCKHOLDER acknowledges that he, and not
the COMPANY or CSI, will pay all taxes due upon receipt of the consideration
payable pursuant to Section 2 hereof, and will assume all tax risks and
liabilities of such STOCKHOLDER in connection with the transactions contemplated
hereby.

single breach or default be deemed a waiver of any other breach or default
occurring before or after that waiver.

        18.12 REFORMATION AND SEVERABILITY. In case any provision of this
Agreement shall beinvalid, illegal or unenforceable, it shall, to the extent
possible, be modified in such manner as to be valid, legal and enforceable but
so as to most nearly retain the intent of the parties, and if such modification
is not possible, such provision shall be severed from this Agreement, and in
either case the validity, legality and enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby.

        18.13 REMEDIES CUMULATIVE. No right, remedy or election given by any

Agreement have the authority to enter into and bind the COMPANY to the terms of

issued, are fully paid and nonassessable, are owned of record by the
STOCKHOLDERS and further, such shares were offered, issued, sold and delivered

      All accrued contribution obligations of COMPANY or any Subsidiary with
respect to any plan listed on Schedule 5.19 have either been fulfilled in their
entirety or are fully reflected on the balance sheet of the COMPANY as of the
Balance Sheet Date.

      or a merger, consolidation or business combination of the COMPANY.

      7.5 NOTICE TO BARGAINING AGENTS. Prior to the Closing Date, the COMPANY
shall satisfy any requirement for notice of the transactions contemplated by

stockholders agreements, voting agreements, voting trusts, options, warrants and
employment agreements between the COMPANY and any employee listed on Schedule
9.12 hereto and (ii) any existing agreement between the COMPANY and any
STOCKHOLDER, on or prior to the Funding and Consummation Date. Such termination
agreements are listed on Schedule 7.6 and copies thereof shall be attached
thereto.

      7.7 NOTIFICATION OF CERTAIN MATTERS. The STOCKHOLDERS and the COMPANY
shall give prompt notice to CSI of (i) the occurrence or non-occurrence of any
event the occurrence or non-occurrence of which would be likely to cause any
representation or warranty of the COMPANY or the STOCKHOLDERS contained herein
to be untrue or inaccurate in any material respect at or prior to the Closing
and (ii) any material failure of any STOCKHOLDER or the COMPANY to comply with
or satisfy any covenant, condition or agreement to be complied with or satisfied
by such person hereunder. CSI shall give prompt notice to the COMPANY of (i) the
occurrence or non-occurrence of any event the occurrence or non-occurrence of
which would be likely to cause any

                                    -38-

representation or warranty of CSI contained herein to be untrue or inaccurate in
any material respect at or prior to the Closing and (ii) any material failure of
CSI to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder. The delivery of any notice pursuant
to this Section 7.7 shall not be deemed to (i) modify the representations or
warranties hereunder of the party delivering such notice, which modification may
only be made pursuant to Section 7.8, (ii) modify the conditions set forth in
Sections 8 and 9, or (iii) limit or otherwise affect the remedies available
hereunder to the party receiving such notice.

      7.8 AMENDMENT OF SCHEDULES. Each party hereto agrees that, with respect to
the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the COMPANY that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless CSI and
a majority of the Founding Companies other than the COMPANY consent to such
amendment or supplement; and provided further, that no amendment or supplement
to a Schedule prepared by CSI that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless a
majority of the Founding Companies consent to such amendment or supplement. For
all purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other
Founding Companies seeks to amend or supplement a Schedule pursuant to Section
7.8 of one of

                                    -39-

the Other Agreements, and such amendment or supplement constitutes or reflects
an event or occurrence that would have a Material Adverse Effect on such Other
Founding Company, CSI shall give the COMPANY notice promptly after it has
knowledge thereof. If CSI and a majority of the Founding Companies consent to
such amendment or supplement, which consent shall have been deemed given by CSI
or any Founding Company if no response is received within 24 hours following
receipt of notice of such amendment or supplement (or sooner if required by the
circumstances under which such consent is requested), but the COMPANY does not
give its consent, the COMPANY may terminate this Agreement pursuant to Section
12.1(iv) hereof. In the event that the COMPANY seeks to amend or supplement a
Schedule pursuant to this Section 7.8, and CSI and a majority of the Other
Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. In the event that CSI seeks to amend or supplement a Schedule
pursuant to this Section 7.8 and a majority of the Founding Companies do not
consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the
anticipated effectiveness of the Registration Statement.

      7.9 COOPERATION IN PREPARATION OF REGISTRATION STATEMENT. The COMPANY and
STOCKHOLDERS shall furnish or cause to be furnished to CSI and the Underwriters
all of the information concerning the COMPANY and the STOCKHOLDERS required for
inclusion in, and will cooperate with CSI and the Underwriters in the
preparation of, the Registration Statement and the prospectus included therein
(including audited and unaudited financial statements, prepared in accordance
with generally accepted accounting principles, in form suitable for inclusion in
the Registration Statement). The COMPANY and the STOCKHOLDERS agree promptly to
advise CSI if at any time during the period in which a prospectus relating to
the offering is required to be delivered under the Securities Act, any
information contained in the prospectus concerning the

                                    -40-

COMPANY or the STOCKHOLDERS becomes incorrect or incomplete in any material
respect, and to provide the information needed to correct such inaccuracy.
Insofar as the information relates solely to the COMPANY or the STOCKHOLDERS,
the COMPANY represents and warrants as to such information with respect to
itself, and each Stockholder represents and warrants, as to such information
with respect to the COMPANY and himself or herself, that the Registration
Statement will not include an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

      7.10 FINAL FINANCIAL STATEMENTS. The COMPANY shall provide prior to the
Funding and Consummation Date, and CSI shall have had sufficient time to review
the unaudited consolidated balance sheets of the COMPANY as of the end of all
fiscal quarters following the Balance Sheet Date, and the unaudited consolidated
statement of income, cash flows and retained earnings of the COMPANY for all
fiscal quarters ended after the Balance Sheet Date, disclosing no material
adverse change in the financial condition of the COMPANY or the results of its
operations from the financial statements as of the Balance Sheet Date. Such
financial statements shall have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis throughout the
periods indicated (except as noted therein). Except as noted in such financial
statements, all of such financial statements will present fairly the results of
operations of the COMPANY for the periods indicated therein.

      7.11 FURTHER ASSURANCES. The parties hereto agree to execute and deliver,
or cause to be executed and delivered, such further instruments or documents or
take such other action as may be reasonably necessary or convenient to carry out
the transactions contemplated hereby.

      7.12 AUTHORIZED CAPITAL. CSI shall maintain its authorized capital stock

application is made to register the CSI Stock.

                                    -41-

      7.13 COMPLIANCE WITH THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF
1976 (THE "HART-SCOTT ACT"). All parties to this Agreement hereby recognize that
one or more filings under the Hart-Scott Act may be required in connection with
the transactions contemplated herein. If it is determined by the parties to this
Agreement that filings under the Hart-Scott Act are required, then: (i) each of
the parties hereto agrees to cooperate and use its best efforts to comply with
the Hart-Scott Act, (ii) such compliance by the STOCKHOLDERS and the COMPANY
shall be deemed a condition precedent in addition to the conditions precedent
set forth in Section 9 of this Agreement, and such compliance by CSI shall be
deemed a condition precedent in addition to the conditions precedent set forth
in Section 8 of this Agreement, and (iii) the parties agree to cooperate and use
their best efforts to cause all filings required under the Hart-Scott Act to be
made. If filings under the Hart-Scott Act are required, the costs and expenses
thereof (including filing fees) shall be borne by CSI.

      7.14 COMPLIANCE WITH AGREEMENT. The STOCKHOLDERS shall cause the COMPANY
to comply with its obligations under this Agreement.

STOCKHOLDER who has not as of that time been released from his or her guarantee
as described above and whose indebtedness as described above has not as of that
time been paid off, refinanced or retired.

                                    -48-

      10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as contemplated

      contemplated hereby; or

            (b) the entering into of financial arrangements for the benefit of
      the STOCKHOLDERS.

      10.3  PREPARATION AND FILING OF TAX RETURNS.

            (i) The COMPANY shall, if possible, file or cause to be filed all
      separate Returns of any Acquired Party for all taxable periods that end on
      or before the Funding and Consummation Date. Notwithstanding the
      foregoing, the STOCKHOLDERS shall file or cause to be filed all separate
      federal income Tax Returns of any Acquired Party for all taxable periods
      that end on or before the Funding and Consummation Date. Each STOCKHOLDER
      shall pay or cause to be paid all Tax liabilities (in excess of all
      amounts already paid with respect thereto or properly accrued or reserved
      with respect thereto on the COMPANY Financial Statements) shown by such
      Returns to be due.

            (ii) CSI shall file or cause to be filed all separate Returns of, or
      that include, any Acquired Party for all taxable periods ending after the
      Funding and Consummation Date.

            (iii) Each party hereto shall, and shall cause its subsidiaries and
      affiliates to, provide to each of the other parties hereto such
      cooperation and information as any of them reasonably may request in
      filing any Return, amended Return or claim for refund, determining a
      liability for Taxes or a right to refund of Taxes or in conducting any
      audit or other proceeding in respect of Taxes. Such cooperation and
      information shall include providing copies of all relevant portions of
      relevant Returns, together with relevant accompanying schedules and
      relevant work papers, relevant documents relating to rulings

                                    -49-

      or other determinations by Taxing Authorities and relevant records
      concerning the ownership and Tax basis of property, which such party may
      possess. Each party shall make its employees reasonably available on a
      mutually convenient basis at its cost to provide explanation of any
      documents or information so provided. Subject to the preceding sentence,
      each party required to file Returns pursuant to this Agreement shall bear
      all costs of filing such Returns.

            (iv) Each of the COMPANY, CSI and each STOCKHOLDER shall comply with
      the tax reporting requirements of Section 1.351-3 of the Treasury
      Regulations promulgated under the Code, and treat the transaction as a
      tax-free contribution under Section 351(a) of the Code subject to gain, if
      any, recognized on the receipt of cash or other property under Section
      351(b) of the Code. 

      10.4 DIRECTORS. The persons named in the draft of the Registration
Statement shall be appointed as directors and elected as officers of CSI, as and
to the extent set forth in the draft of the Registration Statement, promptly
following the Funding and Consummation Date. This provision shall not imply that
the STOCKHOLDERS have any power or duty to elect officers of CSI.

      10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation to provide
replacement plans that have the same terms and provisions as the existing plans,
provided, further, that any new health insurance plan shall provide for coverage
for preexisting conditions. On the Funding and Consummation Date, the employees
of the COMPANY will remain the employees of the COMPANY (provided that this
provision is for purposes of clarifying that the Exchange, in and of itself,
will not have any impact on the employment status of any employee and provided,
further that this provision shall not in any way limit the management rights of
the COMPANY or

                                    -50-

CSI to assess workforce needs and make appropriate adjustments as necessary or
desirable within their discretion subject to applicable laws and collective
bargaining agreements).

      10.6 DIVIDENDS. If the COMPANY is an S corporation, the COMPANY may pay to
each STOCKHOLDER as a dividend the full amount of his or her "accumulated
adjustments account" (as defined in Section 1368(e) of the Code) as of the
Balance Sheet Date, and may also pay to the STOCKHOLDERS as a dividend the full
amount of the COMPANY's earnings taxable to such STOCKHOLDERS for the period
after the Balance Sheet Date to the Funding and Consummation Date. If the
COMPANY is a C corporation, the COMPANY may pay to the STOCKHOLDERS as a
dividend the full amount of the COMPANY's earnings for the period after the
Balance Sheet Date to the Funding and Consummation Date. The COMPANY may borrow
funds to the extent necessary to make the payments contemplated by this Section
10.6 and to the extent necessary to ensure that the COMPANY has cash on hand to
adequately fund operations on the Funding and Consummation Date.

      10.7 ESOP. The COMPANY agrees that it will not make any further
contributions to the ESOP after the date hereof. Subject to applicable law, the
STOCKHOLDERS, the COMPANY and CSI shall use their best efforts:

            (i) to cause the ESOP to refrain from distributing any shares of CSI
      Stock held by the ESOP to any participant therein until such time as the
      shares of CSI Stock held by the ESOP will be, upon distribution to such
      participant, freely tradable without restriction;

            (ii) to cause the interests of all ESOP participants to become fully
      vested on the Funding and Consummation Date or as soon thereafter as may
      be reasonably practicable; and

            (iii) to terminate the ESOP (and distribute the assets thereof to
      the participants therein) as soon as may be reasonably practicable after
      the shares of CSI Stock then held by the ESOP will be, upon distribution
      to the participants in the ESOP, freely tradable without restriction.

                                    -51-

11.   INDEMNIFICATION

      The STOCKHOLDERS and CSI each make the following covenants that are
applicable to them, respectively:

      11.1  GENERAL INDEMNIFICATION BY THE STOCKHOLDERS.  The STOCKHOLDERS

covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless CSI and the COMPANY at all times, from and after the
date of this Agreement until the Expiration Date, from and against all claims,
damages, actions, suits, proceedings, demands, assessments, adjustments, costs
and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by CSI or the COMPANY as
a result of or arising from (i) any breach of the representations and warranties
of the STOCKHOLDERS or the COMPANY set forth herein or on the schedules or
certificates delivered in connection herewith, (ii) any breach of any agreement
on the part of the STOCKHOLDERS or the COMPANY under this Agreement, or (iii)
any liability under the 1933 Act, the 1934 Act or other Federal or state law or
regulation, at common law or otherwise, arising out of or based upon any untrue
statement or alleged untrue statement of a material fact relating to the COMPANY
or the STOCKHOLDERS, and provided to CSI or its counsel by the COMPANY or the
STOCKHOLDERS (but in the case of the STOCKHOLDERS, only if such statement was
provided in writing) contained in the Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto, or
arising out of or based upon any omission or alleged omission to state therein a
material fact relating to the COMPANY or the STOCKHOLDERS required to be stated
therein or necessary to make the statements therein not misleading, provided,
however, that such indemnity shall not inure to the benefit of CSI or the
COMPANY to the extent that such untrue statement (or alleged untrue statement)
was made in, or omission (or alleged omission) occurred in, any preliminary
prospectus and the STOCKHOLDERS provided, in writing, corrected information to
CSI counsel and to CSI for inclusion in the final prospectus, and such
information was not so included or properly delivered, and provided further,
that no STOCKHOLDER shall be liable for any

                                    -52-

indemnification obligation pursuant to this Section 11.1 to the extent
attributable to a breach of any representation, warranty or agreement made
herein individually by any other STOCKHOLDER.

      11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDERS at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
STOCKHOLDERS as a result of or arising from (i) any breach by CSI of its
representations and warranties set forth herein or on the schedules or
certificates attached hereto, (ii) any nonfulfillment of any agreement on the
part of CSI under this Agreement, (iii) any liabilities which the STOCKHOLDERS
may incur due to CSI's failure to be responsible for the liabilities and
obligations of the COMPANY as provided in Section 1 hereof (except to the extent
that CSI has claims against the STOCKHOLDERS by reason of such liabilities); or
(iv) any liability under the 1933 Act, the 1934 Act or other Federal or state
law or regulation, at common law or otherwise, arising out of or based upon any
untrue statement or alleged untrue statement of a material fact relating to CSI
or any of the Other Founding Companies contained in any preliminary prospectus,
the Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to CSI or
any of the Other Founding Companies required to be stated therein or necessary
to make the statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has knowledge of any claim by a
person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or

                                    -53-

the commencement of such action or proceeding. Such notice shall state the
nature and the basis of such claim and a reasonable estimate of the amount
thereof. The Indemnifying Party shall have the right to defend and settle, at
its own expense and by its own counsel, any such matter so long as the
Indemnifying Party pursues the same in good faith and diligently, provided that
the Indemnifying Party shall not settle any criminal proceeding without the
written consent of the Indemnified Party. If the Indemnifying Party undertakes
to defend or settle, it shall promptly notify the Indemnified Party of its
intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or control. All Indemnified Parties shall use the same counsel, which
shall be the counsel selected by Indemnifying Party, provided that if counsel to
the Indemnifying Party shall have a conflict of interest that prevents counsel
for the Indemnifying Party from representing Indemnified Party, Indemnified
Party shall have the right to participate in such matter through counsel of its
own choosing and Indemnifying Party will reimburse the Indemnified Party for the
reasonable expenses of its counsel. After the Indemnifying Party has notified
the Indemnified Party of its intention to undertake to defend or settle any such
asserted liability, and for so long as the Indemnifying Party diligently pursues
such defense, the Indemnifying Party shall not be liable for any additional
legal expenses incurred by the Indemnified Party in connection with any defense
or settlement of such asserted liability, except (i) as set forth in the
preceding sentence and (ii) to the extent such participation is requested by the
Indemnifying Party, in which event the Indemnified Party shall be reimbursed by
the Indemnifying Party for reasonable additional legal expenses and
out-of-pocket expenses. If the Indemnifying Party desires to accept a final and
complete settlement of any such Third Person claim and the Indemnified Party
refuses to consent to such settlement, then the Indemnifying Party's liability
under this Section with respect to such Third Person claim shall be limited to
the amount so offered in settlement by said Third Person. Upon agreement as to
such

                                    -54-

settlement between said Third Person and the Indemnifying Party, the
Indemnifying Party shall, in exchange for a complete release from the
Indemnified Party, promptly pay to the Indemnified Party the amount agreed to in
such settlement and the Indemnified Party shall, from that moment on, bear full
responsibility for any additional costs of defense which it subsequently incurs
with respect to such claim and all additional costs of settlement or judgment.
If the Indemnifying Party does not undertake to defend such matter to which the
Indemnified Party is entitled to indemnification hereunder, or fails diligently
to pursue such defense, the Indemnified Party may undertake such defense through
counsel of its choice, at the cost and expense of the Indemnifying Party, and
the Indemnified Party may settle such matter, and the Indemnifying Party shall
reimburse the Indemnified Party for the amount paid in such settlement and any
other liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the Indemnified Party otherwise agrees in writing. The parties
hereto will make appropriate adjustments for insurance proceeds in determining
the amount of any indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section 11
shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

      11.5 LIMITATIONS ON INDEMNIFICATION. CSI and the other persons or entities
indemnified pursuant to Section 11.1 or 11.2 shall not assert any claim for
indemnification hereunder against the STOCKHOLDERS until such time as, and
solely to the extent that, the aggregate of all claims which such persons may
have against such the STOCKHOLDERS shall exceed the greater of (a) 1.0% of

                                    -55-

the sum of the cash paid to STOCKHOLDERS plus the value of the CSI Stock
delivered to STOCKHOLDERS (calculated as in this Section 11.5) or (b) $50,000
(the "Indemnification Threshold"). STOCKHOLDERS shall not assert any claim for
indemnification hereunder against CSI until such time as, and solely to the
extent that, the aggregate of all claims which STOCKHOLDERS may have against CSI
shall exceed $50,000

      No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

      Notwithstanding any other term of this Agreement, no STOCKHOLDER shall be
liable under this Section 11 for an amount which exceeds the amount of proceeds
received by such STOCKHOLDER in connection with the Exchange. For purposes of
calculating the value of the CSI Stock received by a STOCKHOLDER, CSI Stock
shall be valued at its initial public offering price as set forth in the
Registration Statement. It is hereby understood and agreed that a STOCKHOLDER
may satisfy an indemnification obligation through payment of a combination of
stock and cash in proportion equal to the proportion of stock and cash received
by such STOCKHOLDER in connection with the Exchange, valued as described
immediately above.

      11.6 ADDITIONAL LIMITATION. CSI and the other persons or entities
indemnified pursuant to Section 11.1 or 11.2 shall not assert any claim for
indemnification hereunder against (1) any participant in the ESOP, in his or her
capacity as such, or (2) any trustee of the ESOP in his or her individual
capacity, it being agreed that any claim for indemnification hereunder against
the ESOP shall be made only against the ESOP.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION.This Agreement may be terminated at any time prior to the
Funding and Consummation Date solely:

      (i) by mutual consent of the boards of directors of CSI and the
STOCKHOLDERS;

                                    -56-

      (ii) by the STOCKHOLDERS, on the one hand, or by CSI (acting through its
board of directors), on the other hand, if the transactions contemplated by this
Agreement to take place at the Closing shall not have been consummated by
September 30, 1997, unless the failure of such transactions to be consummated is
due to the willful failure of the party seeking to terminate this Agreement to
perform any of its obligations under this Agreement to the extent required to be
performed by it prior to or on the Funding and Consummation Date;

      (iii) by the STOCKHOLDERS, on the one hand, or by CSI, on the other hand,
if a material breach or default shall be made by the other party in the
observance or in the due and timely performance of any of the covenants or
agreements contained herein, and the curing of such default shall not have been
made on or before the Funding and Consummation Date or by the STOCKHOLDERS or
the COMPANY, if the conditions set forth in Section 8 hereof have not been
satisfied or waived as of the Closing Date or the Funding and Consummation Date,
as applicable, or by CSI, if the conditions set forth in Section 9 hereof have
not been satisfied or waived as of the Closing Date or the Funding and
Consummation Date, as applicable;

      (iv)  pursuant to Section 7.8 hereof; or

      (v)   pursuant to Section 4 hereof.

      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. Mr. Pokorny shall enter into a noncompetition
agreement substantially similar to those described in Section 13 of the Other
Agreements.

                                    -57-

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1  STOCKHOLDERS. The STOCKHOLDERS recognize and acknowledge that they

had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. The STOCKHOLDERS agree that they
will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except (a) to authorized representatives of CSI, (b) following the Closing, such
information may be disclosed by the STOCKHOLDERS as is required in the course of
performing their duties for CSI or the COMPANY and (c) to counsel and other
advisers, provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 14.1, unless (i) such information
becomes known to the public generally through no fault of the STOCKHOLDERS, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), the STOCKHOLDERS shall, if possible, give prior written notice
thereof to CSI and provide CSI with the opportunity to contest such disclosure,
or (iii) the disclosing party reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party. In the event of a breach or threatened breach by any of the STOCKHOLDERS
of the provisions of this Section, CSI shall be entitled to an injunction
restraining such STOCKHOLDERS from disclosing, in whole or in part, such
confidential information. Nothing herein shall be construed as prohibiting CSI
from pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. In the event the transactions contemplated by
this Agreement are not consummated, STOCKHOLDERS shall have none of the
above-mentioned restrictions on their ability to disseminate confidential
information with respect to the COMPANY.

                                    -58-

      14.2 CSI. CSI recognizes and acknowledges it had in the past and currently
has access to certain confidential information of the COMPANY, such as
operational policies, and pricing and cost policies that are valuable, special
and unique assets of the COMPANY's business. CSI agrees that, prior to the
Closing, or if the Transactions contemplated by this Agreement are not
consummated, they will not disclose such confidential information to any person,
firm, corporation, association or other entity for any purpose or reason
whatsoever, except (a) to authorized representatives of the COMPANY, (b) to
counsel and other advisers, provided that such advisers (other than counsel)
agree to the confidentiality provisions of this Section 14.1, (c) to the Other
Founding Companies and their representatives pursuant to Section 7.1(a), unless
(i) such information becomes known to the public generally through no fault of
CSI, (ii) disclosure is required by law or the order of any governmental
authority under color of law, provided, that prior to disclosing any information
pursuant to this clause (ii), CSI shall, if possible, give prior written notice
thereof to the COMPANY and the STOCKHOLDERS and provide the COMPANY and the
STOCKHOLDERS with the opportunity to contest such disclosure, or (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, and (d)
to the public to the extent necessary or advisable in connection with the filing
of the Registration Statement and the IPO and the securities laws applicable
thereto and to the operation of CSI as a publicly held entity after the IPO. In
the event of a breach or threatened breach by CSI of the provisions of this
Section, the COMPANY and the STOCKHOLDERS shall be entitled to an injunction
restraining CSI from disclosing, in whole or in part, such confidential
information. Nothing herein shall be construed as prohibiting the COMPANY and
the STOCKHOLDERS from pursuing any other available remedy for such breach or
threatened breach, including the recovery of damages.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the

                                    -59-

parties hereto agree that, in the event of a breach by any of them of the
foregoing covenants, the covenant may be enforced against the other parties by
injunctions and restraining orders.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Funding and Consummation Date.

15.   TRANSFER RESTRICTIONS

      15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDERS or family members, the trustees
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the STOCKHOLDERS shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of CSI Stock as described in Section 3.1 received by the STOCKHOLDERS in
the Exchange. The certificates evidencing the CSI Stock delivered to the
STOCKHOLDERS pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as CSI may deem necessary or appropriate: THE SHARES REPRESENTED BY THIS
CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED,
PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL
NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE,
TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION
PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE WRITTEN REQUEST OF THE
HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND
(AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED
ABOVE.

                                    -60-

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The STOCKHOLDERS acknowledge that the shares of
CSI Stock to be delivered to the STOCKHOLDERS pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and may not be resold without compliance with the Act. The CSI Stock
to be acquired by such STOCKHOLDERS pursuant to this Agreement is being acquired
solely for their own respective accounts, for investment purposes only, and with
no present intention of distributing, selling or otherwise disposing of it in
connection with a distribution. The STOCKHOLDERS covenant, warrant and represent
that none of the shares of CSI Stock issued to such STOCKHOLDERS will be
offered, sold, assigned, pledged, hypothecated, transferred or otherwise
disposed of except after full compliance with all of the applicable provisions
of the Act and the rules and regulations of the SEC. All the CSI Stock shall
bear the following legend in addition to the legend required under Section 15 of
this Agreement: THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED
IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

      16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDERS are able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and have
such knowledge and experience in financial and business matters that they are
capable of evaluating the merits and risks of the proposed investment in the CSI
Stock. The STOCKHOLDERS party hereto have had an adequate opportunity to ask
questions and receive answers from the officers of CSI concerning any and all
matters relating to the transactions described herein including, without
limitation, the background and experience of the current and proposed officers
and directors of CSI, the plans for the operations of the business

                                    -61-

of CSI, the business, operations and financial condition of the Founding
Companies other than the COMPANY, and any plans for additional acquisitions and
the like. The STOCKHOLDERS have asked any and all questions in the nature
described in the preceding sentence and all questions have been answered to
their satisfaction.

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
each of the STOCKHOLDERS prompt written notice of its intent to do so. Upon the
written request of any of the STOCKHOLDERS given within 30 days after receipt of
such notice, CSI shall cause to be included in such registration all of the CSI
Stock issued to the STOCKHOLDERS pursuant to this Agreement (including any stock
issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) which any such STOCKHOLDER requests, provided that CSI shall
have the right to reduce the number of shares included in such registration to
the extent that inclusion of such shares could, in the opinion of tax counsel to
CSI or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Registration Statement as a tax-free
organization. In addition, if CSI is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1 that the number
of shares to be sold by persons other than CSI is greater than the number of
such shares which can be offered without adversely affecting the offering, CSI
may reduce pro rata the number of shares offered for the accounts of such
persons (based upon the number of shares held by such person) to a number deemed
satisfactory by such managing underwriter, provided, that, for each

                                    -62-

such offering made by CSI after the IPO, such reduction shall be made first by
reducing the number of shares to be sold by persons other than CSI, the
STOCKHOLDERS and the stockholders of the Other Founding Companies (collectively,
the STOCKHOLDERS and the stockholders of the other Founding Companies being
referred to herein as the "Founding Stockholders"), and thereafter, if a further
reduction is required, by reducing the number of shares to be sold by the
Founding Stockholders.

      17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year after
the Closing and prior to the date three years after the Closing, the holders of
a majority of the shares of CSI Stock issued to the Founding Stockholders
pursuant to this Agreement and the Other Agreements which have not been
previously registered or sold and which are not entitled to be sold under Rule
144(k) (or any similar or successor provision) promulgated under the 1933 Act
may request in writing that CSI file a registration statement under the 1933 Act
covering the registration of the shares of CSI Stock issued to the STOCKHOLDERS
pursuant to this Agreement and the Other Agreements (including any stock issued
as (or issuable upon the conversion or exchange of any convertible security,
warrant, right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) then held by such Founding Stockholders (a "Demand Registration"). Within
ten (10) days of the receipt of such request, CSI shall give written notice of
such request to all other Founding Stockholders and shall, as soon as
practicable but in no event later than 45 days after notice from any
STOCKHOLDER, file and use its best efforts to cause to become effective a
registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

      Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the

                                    -63-

date on which CSI would otherwise be required to make such filing pursuant to
the foregoing paragraph.

      If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective date of such registration unless CSI is no longer proceeding
diligently to effect such registration; provided that CSI shall provide the
Founding Stockholders the right to participate in such public offering pursuant
to, and subject to, Section 17.1 hereof.

      17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with the
registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Sections 17.1 and 17.2 covering an underwritten registered offering, CSI and
each participating holder agree to enter into a written agreement with the
managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such

                                    -64-

managing underwriters and companies of CSI's size and investment stature,
including indemnification.

      17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by any STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to such STOCKHOLDER.

      17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

            (i) make and keep public information regarding CSI available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of CSI under the 1933 Act and the 1934 Act at any time
      after it has become subject to such reporting requirements; and

            (iii) so long as a STOCKHOLDER owns any restricted CSI Common Stock,
      furnish to each STOCKHOLDER forthwith upon written request a written
      statement by CSI as to its compliance with the reporting requirements of
      Rule 144 (at any time from and after 90 days following the effective date
      of the Registration Statement, and of the 1933 Act and the 1934 Act (at
      any time after it has become subject to such reporting requirements), a
      copy of the most recent annual or quarterly report of CSI, and such other
      reports and documents so filed as a STOCKHOLDER may reasonably request in
      availing itself of any rule or regulation of the SEC allowing a
      STOCKHOLDER to sell any such shares without registration.

                                    -65-

      18.   GENERAL

      18.1 COOPERATION. The COMPANY, STOCKHOLDERS and CSI shall each deliver or
cause to be delivered to the other on the Funding and Consummation Date, and at
such other times and places as shall be reasonably agreed to, such additional
instruments as the other may reasonably request for the purpose of carrying out
this Agreement. The COMPANY will cooperate and use its reasonable efforts to
have the present officers, directors and employees of the COMPANY cooperate with

promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the COMPANY that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless CSI and
a majority of the Founding Companies other than the COMPANY consent to such
amendment or supplement; and provided further, that no amendment or supplement
to a Schedule prepared by CSI or NEWCO that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless a

determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended

has knowledge thereof. If CSI and a majority of the Founding Companies consent
to such amendment or supplement, which consent shall have been deemed given by
CSI or any Founding Company if no response is received within 24 hours following
receipt of notice of such amendment or supplement (or sooner if required by the
circumstances under which such consent is requested), but the COMPANY does not
give its consent, the COMPANY may terminate this Agreement pursuant to Section
12.1(iv) hereof. In the event that the COMPANY seeks to amend or supplement a
Schedule pursuant to this Section 7.8, and CSI and a majority of the Other
Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. In the event that CSI or NEWCO seeks to amend or supplement a
Schedule pursuant to this Section 7.8 and a majority of the Founding Companies
do not consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the

any material respect, and to provide the information needed to correct such
inaccuracy. Insofar as the information relates solely to the COMPANY or the
STOCKHOLDERS, the COMPANY represents and warrants as to such information with
respect to itself, and each Stockholder represents and warrants, as to such
information with respect to the COMPANY and himself or herself, that the
Registration Statement will not include an untrue statement of a material fact

the transactions contemplated herein. If it is determined by the parties to this
Agreement that filings under the Hart-Scott Act are required, then: (i) each of
the parties hereto agrees to cooperate and use its best efforts to comply with
the Hart-Scott Act, (ii) such compliance by the STOCKHOLDERS and the COMPANY

      foregoing, the STOCKHOLDERS shall file or cause to be filed all separate
      federal income Tax Returns (and any State and local Tax Returns filed on
      the basis similar to that of S corporations under federal income Tax
      rules) of any Acquired Party for all taxable periods that end on or before
      the Funding and Consummation Date. Each STOCKHOLDER shall pay or cause to
      be paid all Tax liabilities (in excess of all amounts already paid with
      respect thereto or properly accrued or reserved with respect thereto on
      the COMPANY Financial Statements) shown by such Returns to be due.

            (ii) CSI shall file or cause to be filed all separate Returns of, or
      that include, any Acquired Party for all taxable periods ending after the
      Funding and Consummation Date.

                                    -52-

            (iii) Each party hereto shall, and shall cause its subsidiaries and
      affiliates to, provide to each of the other parties hereto such
      cooperation and information as any of them reasonably may request in
      filing any Return, amended Return or claim for refund, determining a
      liability for Taxes or a right to refund of Taxes or in conducting any
      audit or other proceeding in respect of Taxes. Such cooperation and
      information shall include providing copies of all relevant portions of
      relevant Returns, together with relevant accompanying schedules and
      relevant work papers, relevant documents relating to rulings or other
      determinations by Taxing Authorities and relevant records concerning the
      ownership and Tax basis of property, which such party may possess. Each
      party shall make its employees reasonably available on a mutually
      convenient basis at its cost to provide explanation of any documents or
      information so provided. Subject to the preceding sentence, each party
      required to file Returns pursuant to this Agreement shall bear all costs
      of filing such Returns.

            (iv) Each of the COMPANY, NEWCO, CSI and each STOCKHOLDER shall
      comply with the tax reporting requirements of Section 1.351-3 of the
      Treasury Regulations promulgated under the Code, and treat the transaction
      as a tax-free contribution under Section 351(a) of the Code subject to
      gain, if any, recognized on the receipt of cash or other property under
      Section 351(b) of the Code. 10.4 DIRECTORS. The persons named in the draft
      of the Registration Statement shall be

appointed as directors and elected as officers of CSI, as and to the extent set
forth in the draft of the Registration Statement, promptly following the Funding
and Consummation Date. This provision shall not imply that the STOCKHOLDERS have
any power or duty to elect officers of CSI.

      10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation

                                    -53-

to provide replacement plans that have the same terms and provisions as the
existing plans, provided, further, that any new health insurance plan shall
provide for coverage for preexisting conditions. On the Funding and Consummation
Date, the employees of the COMPANY will be the employees of the Surviving
Corporation (provided that this provision is for purposes of clarifying that the
Merger, in and of itself, will not have any impact on the employment status of
any employee and provided, further that this provision shall not in any way
limit the management rights of the Surviving Corporation or CSI to assess
workforce needs and make appropriate adjustments as necessary or desirable
within their discretion subject to applicable laws and collective bargaining
agreements).

      10.6 DIVIDENDS. If the COMPANY is an S corporation, the COMPANY may pay to
each STOCKHOLDER as a dividend the full amount of his or her "accumulated
adjustments account" (as defined in Section 1368(e) of the Code) as of the
Balance Sheet Date, and may also pay to the STOCKHOLDERS as a dividend the full
amount of the COMPANY's earnings taxable to such STOCKHOLDERS for the period
after the Balance Sheet Date to the Funding and Consummation Date. If the
COMPANY is a C corporation, the COMPANY may pay to the STOCKHOLDERS as a
dividend the full amount of the COMPANY's earnings for the period after the
Balance Sheet Date to the Funding and Consummation Date. The COMPANY may borrow
funds to the extent necessary to make the payments contemplated by this Section
10.6 and to the extent necessary to ensure that the COMPANY has cash on hand to
adequately fund operations on the Funding and Consummation Date.

11.   INDEMNIFICATION

      The STOCKHOLDERS, CSI and NEWCO each make the following covenants that are
applicable to them, respectively:

      11.1  GENERAL INDEMNIFICATION BY THE STOCKHOLDERS.  The STOCKHOLDERS
covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless CSI, NEWCO, the COMPANY and the Surviving Corporation
at all times, from and after the date

                                    -54-

of this Agreement until the Expiration Date, from and against all claims,
damages, actions, suits, proceedings, demands, assessments, adjustments, costs
and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by CSI, NEWCO, the
COMPANY or the Surviving Corporation as a result of or arising from (i) any
breach of the representations and warranties of the STOCKHOLDERS or the COMPANY
set forth herein or on the schedules or certificates delivered in connection
herewith, (ii) any breach of any agreement on the part of the STOCKHOLDERS or
the COMPANY under this Agreement, or (iii) any liability under the 1933 Act, the
1934 Act or other Federal or state law or regulation, at common law or
otherwise, arising out of or based upon any untrue statement or alleged untrue
statement of a material fact relating to the COMPANY or the STOCKHOLDERS, and
provided to CSI or its counsel by the COMPANY or the STOCKHOLDERS (but in the
case of the STOCKHOLDERS, only if such statement was provided in writing)
contained in the Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or arising out of or
based upon any omission or alleged omission to state therein a material fact
relating to the COMPANY or the STOCKHOLDERS required to be stated therein or
necessary to make the statements therein not misleading, provided, however, that
such indemnity shall not inure to the benefit of CSI, NEWCO, the COMPANY or the
Surviving Corporation to the extent that such untrue statement (or alleged
untrue statement) was made in, or omission (or alleged omission) occurred in,
any preliminary prospectus and the STOCKHOLDERS provided, in writing, corrected
information to CSI counsel and to CSI for inclusion in the final prospectus, and
such information was not so included or properly delivered, and provided
further, that no STOCKHOLDER shall be liable for any indemnification obligation
pursuant to this Section 11.1 to the extent attributable to a breach of any
representation, warranty or agreement made herein individually by any other
STOCKHOLDER.

      11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDERS at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits,

                                    -55-

proceedings, demands, assessments, adjustments, costs and expenses (including
specifically, but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by the STOCKHOLDERS as a result of or arising from (i)
any breach by CSI or NEWCO of their representations and warranties set forth
herein or on the schedules or certificates attached hereto, (ii) any
nonfulfillment of any agreement on the part of CSI or NEWCO under this
Agreement, (iii) any liabilities which the STOCKHOLDERS may incur due to CSI's
or NEWCO's failure to be responsible for the liabilities and obligations of the
COMPANY as provided in Section 1 hereof (except to the extent that CSI or NEWCO
has claims against the STOCKHOLDERS by reason of such liabilities); or (iv) any
liability under the 1933 Act, the 1934 Act or other Federal or state law or
regulation, at common law or otherwise, arising out of or based upon any untrue
statement or alleged untrue statement of a material fact relating to CSI, NEWCO
or any of the Other Founding Companies contained in any preliminary prospectus,
the Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to CSI or
NEWCO or any of the Other Founding Companies required to be stated therein or
necessary to make the statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has knowledge of any claim by a
person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying

                                    -56-

Party shall not settle any criminal proceeding without the written consent of
the Indemnified Party. If the Indemnifying Party undertakes to defend or settle,
it shall promptly notify the Indemnified Party of its intention to do so, and
the Indemnified Party shall cooperate with the Indemnifying Party and its
counsel in the defense thereof and in any settlement thereof. Such cooperation
shall include, but shall not be limited to, furnishing the Indemnifying Party
with any books, records or information reasonably requested by the Indemnifying
Party that are in the Indemnified Party's possession or control. All Indemnified
Parties shall use the same counsel, which shall be the counsel selected by
Indemnifying Party, provided that if counsel to the Indemnifying Party shall
have a conflict of interest that prevents counsel for the Indemnifying Party
from representing Indemnified Party, Indemnified Party shall have the right to
participate in such matter through counsel of its own choosing and Indemnifying
Party will reimburse the Indemnified Party for the reasonable expenses of its
counsel. After the Indemnifying Party has notified the Indemnified Party of its
intention to undertake to defend or settle any such asserted liability, and for
so long as the Indemnifying Party diligently pursues such defense, the
Indemnifying Party shall not be liable for any additional legal expenses
incurred by the Indemnified Party in connection with any defense or settlement
of such asserted liability, except (i) as set forth in the preceding sentence
and (ii) to the extent such participation is requested by the Indemnifying
Party, in which event the Indemnified Party shall be reimbursed by the
Indemnifying Party for reasonable additional legal expenses and out-of-pocket
expenses. If the Indemnifying Party desires to accept a final and complete
settlement of any such Third Person claim and the Indemnified Party refuses to
consent to such settlement, then the Indemnifying Party's liability under this
Section with respect to such Third Person claim shall be limited to the amount
so offered in settlement by said Third Person. Upon agreement as to such
settlement between said Third Person and the Indemnifying Party, the
Indemnifying Party shall, in exchange for a complete release from the
Indemnified Party, promptly pay to the Indemnified Party the amount agreed to in
such settlement and the Indemnified Party shall, from that moment on, bear full
responsibility for any additional costs of defense which it subsequently incurs
with respect to

                                    -57-

such claim and all additional costs of settlement or judgment. If the
Indemnifying Party does not undertake to defend such matter to which the
Indemnified Party is entitled to indemnification hereunder, or fails diligently
to pursue such defense, the Indemnified Party may undertake such defense through
counsel of its choice, at the cost and expense of the Indemnifying Party, and
the Indemnified Party may settle such matter, and the Indemnifying Party shall
reimburse the Indemnified Party for the amount paid in such settlement and any
other liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the Indemnified Party otherwise agrees in writing. The parties
hereto will make appropriate adjustments for insurance proceeds in determining
the amount of any indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section 11
shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

      11.5 LIMITATIONS ON INDEMNIFICATION. CSI, NEWCO, the Surviving Corporation
and the other persons or entities indemnified pursuant to Section 11.1 or 11.2
shall not assert any claim for indemnification hereunder against the
STOCKHOLDERS until such time as, and solely to the extent that, the aggregate of
all claims which such persons may have against such the STOCKHOLDERS shall
exceed the greater of (a) 1.0% of the sum of the cash paid to STOCKHOLDERS plus
the value of the CSI Stock delivered to STOCKHOLDERS (calculated as provided in
the this Section 11.5) or (b) $50,000 (the "Indemnification Threshold").
STOCKHOLDERS shall not assert any claim for indemnification hereunder against
CSI or NEWCO until such time as, and solely to the extent that,

                                    -58-

the aggregate of all claims which STOCKHOLDERS may have against CSI or NEWCO
shall exceed $50,000.

      No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

      Notwithstanding any other term of this Agreement, no STOCKHOLDER shall be
liable under this Section 11 for an amount which exceeds the amount of proceeds
received by such STOCKHOLDER in connection with the Merger. For purposes of
calculating the value of the CSI Stock received by a STOCKHOLDER, CSI Stock
shall be valued at its initial public offering price as set forth in the
Registration Statement. It is hereby understood and agreed that a STOCKHOLDER
may satisfy an indemnification obligation through payment of a combination of
stock and cash in proportion equal to the proportion of stock and cash received
by such STOCKHOLDER in connection with the Merger, valued as described
immediately above.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION.This Agreement may be terminated at any time prior to the
Funding and Consummation Date solely:

      (i)   by mutual consent of the boards of directors of CSI and the COMPANY;

            (ii) by the STOCKHOLDERS or the COMPANY (acting through its board of
      directors),

on the one hand, or by CSI (acting through its board of directors), on the other
hand, if the transactions contemplated by this Agreement to take place at the
Closing shall not have been consummated by September 30, 1997, unless the
failure of such transactions to be consummated is due to the willful failure of
the party seeking to terminate this Agreement to perform any of its obligations
under this Agreement to the extent required to be performed by it prior to or on
the Funding and Consummation Date;

      (iii) by the STOCKHOLDERS or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due

                                    -59-

and timely performance of any of the covenants or agreements contained herein,
and the curing of such default shall not have been made on or before the Funding
and Consummation Date or by the STOCKHOLDERS or the COMPANY, if the conditions
set forth in Section 8 hereof have not been satisfied or waived as of the
Closing Date or the Funding and Consummation Date, as applicable, or by CSI, if
the conditions set forth in Section 9 hereof have not been satisfied or waived
as of the Closing Date or the Funding and Consummation Date, as applicable;

      (iv)  pursuant to Section 7.8 hereof; or

      (v)   pursuant to Section 4 hereof.

      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. The STOCKHOLDERS will not, for a period of
five (5) years following the Funding and Consummation Date, for any reason
whatsoever, directly or indirectly, for themselves or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

      (i) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial capacity, whether as an employee, independent
contractor, consultant or advisor, or as a sales representative, in any heating,
ventilating or air conditioning services business in direct competition with CSI
or any of the subsidiaries thereof, within 100 miles of where the COMPANY or any
of its subsidiaries conducted business prior to the effectiveness of the Merger
(the "Territory");

                                    -60-

      (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the subsidiaries
thereof), provided that each STOCKHOLDER shall be permitted to call upon and
hire any member of his or her immediate family;

      (iii) call upon any person or entity which is, at that time, or which has
been, within one (1) year prior to the Funding and Consummation Date, a customer
of CSI (including the subsidiaries thereof), of the COMPANY or of any of the
Other Founding Companies within the Territory for the purpose of soliciting or
selling products or services in direct competition with CSI within the
Territory;

      (iv) call upon any prospective acquisition candidate, on any STOCKHOLDER's
own behalf or on behalf of any competitor in the heating, ventilation or air
conditioning services business, which candidate, to the actual knowledge of such
STOCKHOLDER after due inquiry, was called upon by CSI (including the
subsidiaries thereof) or for which, to the actual knowledge of such STOCKHOLDER
after due inquiry, CSI (or any subsidiary thereof) made an acquisition analysis,
for the purpose of acquiring such entity; or

      (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that

                                    -61-

could be caused to CSI for which it would have no other adequate remedy, each
STOCKHOLDER agrees that the foregoing covenant may be enforced by CSI in the
event of breach by such STOCKHOLDER, by injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDERS in light of the activities and business of CSI (including the
subsidiaries thereof) on the date of the execution of this Agreement and the
current plans of CSI.

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of each STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which such
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

      13.6 MATERIALITY. The COMPANY and the STOCKHOLDERS hereby agree that this
covenant is a material and substantial part of this transaction.

                                    -62-

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1  STOCKHOLDERS. The STOCKHOLDERS recognize and acknowledge that they

had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. The STOCKHOLDERS agree that they
will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except (a) to authorized representatives of CSI, (b) following the Closing, such
information may be disclosed by the STOCKHOLDERS as is required in the course of
performing their duties for CSI or the Surviving Corporation and (c) to counsel
and other advisers, provided that such advisers (other than counsel) agree to
the confidentiality provisions of this Section 14.1, unless (i) such information
becomes known to the public generally through no fault of the STOCKHOLDERS, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), the STOCKHOLDERS shall, if possible, give prior written notice
thereof to CSI and provide CSI with the opportunity to contest such disclosure,
or (iii) the disclosing party reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party. In the event of a breach or threatened breach by any of the STOCKHOLDERS
of the provisions of this Section, CSI shall be entitled to an injunction
restraining such STOCKHOLDERS from disclosing, in whole or in part, such
confidential information. Nothing herein shall be construed as prohibiting CSI
from pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. In the event the transactions contemplated by
this Agreement are not consummated, STOCKHOLDERS shall have none of the
above-mentioned restrictions on their ability to disseminate confidential
information with respect to the COMPANY.

                                    -63-

      14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they had
in the past and currently have access to certain confidential information of the
COMPANY, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, (c) to the Other Founding Companies and their representatives pursuant to
Section 7.1(a), unless (i) such information becomes known to the public
generally through no fault of CSI or NEWCO, (ii) disclosure is required by law
or the order of any governmental authority under color of law, provided, that
prior to disclosing any information pursuant to this clause (ii), CSI and NEWCO
shall, if possible, give prior written notice thereof to the COMPANY and the
STOCKHOLDERS and provide the COMPANY and the STOCKHOLDERS with the opportunity
to contest such disclosure, or (iii) the disclosing party reasonably believes
that such disclosure is required in connection with the defense of a lawsuit
against the disclosing party, and (d) to the public to the extent necessary or
advisable in connection with the filing of the Registration Statement and the
IPO and the securities laws applicable thereto and to the operation of CSI as a
publicly held entity after the IPO. In the event of a breach or threatened
breach by CSI or NEWCO of the provisions of this Section, the COMPANY and the
STOCKHOLDERS shall be entitled to an injunction restraining CSI and NEWCO from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting the COMPANY and the STOCKHOLDERS from pursuing
any other available remedy for such breach or threatened breach, including the
recovery of damages.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and

                                    -64-

irreparable damage that would be caused for which they would have no other
adequate remedy, the parties hereto agree that, in the event of a breach by any
of them of the foregoing covenants, the covenant may be enforced against the
other parties by injunctions and restraining orders.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Funding and Consummation Date.

15.   TRANSFER RESTRICTIONS

      15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDERS or family members, the trustees
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the STOCKHOLDERS shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of CSI Stock as described in Section 3.1 received by the STOCKHOLDERS in
the Merger. The certificates evidencing the CSI Stock delivered to the
STOCKHOLDERS pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as CSI may deem necessary or appropriate: THE SHARES REPRESENTED BY THIS
CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED,
PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL
NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE,
TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION
PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE WRITTEN REQUEST OF THE
HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND
(AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED
ABOVE.

                                    -65-

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The STOCKHOLDERS acknowledge that the shares of
CSI Stock to be delivered to the STOCKHOLDERS pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and may not be resold without compliance with the Act. The CSI Stock
to be acquired by such STOCKHOLDERS pursuant to this Agreement is being acquired
solely for their own respective accounts, for investment purposes only, and with
no present intention of distributing, selling or otherwise disposing of it in
connection with a distribution. The STOCKHOLDERS covenant, warrant and represent
that none of the shares of CSI Stock issued to such STOCKHOLDERS will be
offered, sold, assigned, pledged, hypothecated, transferred or otherwise
disposed of except after full compliance with all of the applicable provisions
of the Act and the rules and regulations of the SEC. All the CSI Stock shall
bear the following legend in addition to the legend required under Section 15 of
this Agreement: THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED
IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

      16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDERS are able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and have
such knowledge and experience in financial and business matters that they are
capable of evaluating the merits and risks of the proposed investment in the CSI
Stock. The STOCKHOLDERS party hereto have had an adequate opportunity to ask
questions and receive answers from the officers of CSI concerning any and all
matters relating to the transactions described herein including, without
limitation, the background and experience of the current and proposed officers
and directors of CSI, the plans for the operations of the business of CSI, the
business, operations and financial condition of the Founding Companies other
than the

                                    -66-

COMPANY, and any plans for additional acquisitions and the like. The
STOCKHOLDERS have asked any and all questions in the nature described in the
preceding sentence and all questions have been answered to their satisfaction.

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
each of the STOCKHOLDERS prompt written notice of its intent to do so. Upon the
written request of any of the STOCKHOLDERS given within 30 days after receipt of
such notice, CSI shall cause to be included in such registration all of the CSI
Stock issued to the STOCKHOLDERS pursuant to this Agreement (including any stock
issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) which any such STOCKHOLDER requests, provided that CSI shall
have the right to reduce the number of shares included in such registration to
the extent that inclusion of such shares could, in the opinion of tax counsel to
CSI or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Registration Statement as a tax-free
organization. In addition, if CSI is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1 that the number
of shares to be sold by persons other than CSI is greater than the number of
such shares which can be offered without adversely affecting the offering, CSI
may reduce pro rata the number of shares offered for the accounts of such
persons (based upon the number of shares held by such person) to a number deemed
satisfactory by such managing underwriter, provided, that, for each such
offering made by CSI after the IPO, such reduction shall be made first by
reducing the number

                                    -67-

of shares to be sold by persons other than CSI, the STOCKHOLDERS and the
stockholders of the Other Founding Companies (collectively, the STOCKHOLDERS and
the stockholders of the other Founding Companies being referred to herein as the
"Founding Stockholders"), and thereafter, if a further reduction is required, by
reducing the number of shares to be sold by the Founding Stockholders.

      17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year after
the Closing and prior to the date three years after the Closing, the holders of
a majority of the shares of CSI Stock issued to the Founding Stockholders
pursuant to this Agreement and the Other Agreements which have not been
previously registered or sold and which are not entitled to be sold under Rule
144(k) (or any similar or successor provision) promulgated under the 1933 Act
may request in writing that CSI file a registration statement under the 1933 Act
covering the registration of the shares of CSI Stock issued to the STOCKHOLDERS
pursuant to this Agreement and the Other Agreements (including any stock issued
as (or issuable upon the conversion or exchange of any convertible security,
warrant, right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) then held by such Founding Stockholders (a "Demand Registration"). Within
ten (10) days of the receipt of such request, CSI shall give written notice of
such request to all other Founding Stockholders and shall, as soon as
practicable but in no event later than 45 days after notice from any
STOCKHOLDER, file and use its best efforts to cause to become effective a
registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

      Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the

                                    -68-

date on which CSI would otherwise be required to make such filing pursuant to
the foregoing paragraph.

      If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective date of such registration unless CSI is no longer proceeding
diligently to effect such registration; provided that CSI shall provide the
Founding Stockholders the right to participate in such public offering pursuant
to, and subject to, Section 17.1 hereof.

      17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with the
registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Sections 17.1 and 17.2 covering an underwritten registered offering, CSI and
each participating holder agree to enter into a written agreement with the
managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such

                                    -69-

managing underwriters and companies of CSI's size and investment stature,
including indemnification.

      17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by any STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to such STOCKHOLDER.

      17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

            (i) make and keep public information regarding CSI available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of CSI under the 1933 Act and the 1934 Act at any time
      after it has become subject to such reporting requirements; and

            (iii) so long as a STOCKHOLDER owns any restricted CSI Common Stock,
      furnish to each STOCKHOLDER forthwith upon written request a written
      statement by CSI as to its compliance with the reporting requirements of
      Rule 144 (at any time from and after 90 days following the effective date
      of the Registration Statement, and of the 1933 Act and the 1934 Act (at
      any time after it has become subject to such reporting requirements), a
      copy of the most recent annual or quarterly report of CSI, and such other
      reports and documents so filed as a STOCKHOLDER may reasonably request in
      availing itself of any rule or regulation of the SEC allowing a
      STOCKHOLDER to sell any such shares without registration.

      18.   GENERAL

      18.1 COOPERATION. The COMPANY, STOCKHOLDERS, CSI and NEWCO shall each

interruptions over the past three years.

The COMPANY believes its relationship with employees to be good.

        5.19 EMPLOYEE PLANS. The STOCKHOLDER have delivered to CSI an accurate
schedule (Schedule 5.19) showing all employee benefit plans of COMPANY
(including COMPANY's Subsidiaries), including all employment agreements and
other agreements or arrangements containing "golden parachute" or other similar
provisions, and deferred compensation agreements, together with true, complete
and correct copies of such plans, agreements and any trusts related thereto, and
classifications of employees covered thereby as of the Balance Sheet Date.
Except for the employee benefit plans, if any, described on Schedule 5.19,
COMPANY (including the COMPANY's Subsidiaries) does not sponsor, maintain or
contribute to any plan program, fund or arrangement that constitutes an
"employee pension benefit plan," nor has COMPANY or any Subsidiary any
obligation to contribute to or accrue or pay any benefits under any deferred
compensation or retirement funding arrangement on behalf of any employee or
employees (such as, for example, and without limitation, any individual
retirement account or annuity, any "excess benefit plan" (within the meaning of
Section 3(36) of the Employee Retirement Income Security Act

                                      -21-


of 1974, as amended ("ERISA")) or any non-qualified deferred compensation
arrangement). For the purposes of this Agreement, the term "employee pension
benefit plan" shall have the same meaning as is given that term in Section 3(2)
of ERISA. Neither COMPANY nor any Subsidiary has sponsored, maintained or
contributed to any employee pension benefit plan other than the plans set forth
on Schedule 5.19, nor is COMPANY or any Subsidiary required to contribute to any
retirement plan pursuant to the provisions of any collective bargaining
agreement establishing the terms and conditions or employment of any of
COMPANY's or any Subsidiary's employees.

        Neither the COMPANY nor any Subsidiary is now, or can as a result of its
past activities become, liable to the Pension Benefit Guaranty Corporation or to
any multiemployer employee pension benefit plan under the provisions of Title IV
of ERISA.

        All employee benefit plans listed on Schedule 5.19 and the
administration thereof are in substantial compliance with their terms and all
applicable provisions of ERISA and the regulations issued thereunder, as well as
with all other applicable federal, state and local statutes, ordinances and
regulations.

        All accrued contribution obligations of COMPANY or any Subsidiary with
respect to any plan listed on Schedule 5.19 have either been fulfilled in their
entirety or are fully reflected on the balance sheet of the COMPANY as of the
Balance Sheet Date.

        5.20 COMPLIANCE WITH ERISA. All such plans listed on Schedule 5.19 that
are intended to qualify (the "Qualified Plans") under Section 401(a) of the Code
are, and have been so qualified and have been determined by the Internal Revenue
Service to be so qualified, and copies of such determination letters are
included as part of Schedule 5.19 hereof. Except as disclosed on Schedule 5.20,
all reports and other documents required to be filed with any governmental
agency or distributed to plan participants or beneficiaries (including, but not
limited to, actuarial reports, audits or tax returns) have been timely filed or
distributed, and copies thereof are included as part of Schedule 5.19 hereof.
Neither STOCKHOLDER, any such plan listed in Schedule 5.19, nor COMPANY
(including the COMPANY's Subsidiaries) has engaged in any transaction prohibited

                                      -22-


under the provisions of Section 4975 of the Code or Section 406 of ERISA. No
such Plan listed in Schedule 5.19 has incurred an accumulated funding
deficiency, as defined in Section 412(a) of the Code and Section 302(1) of
ERISA; and COMPANY (including the COMPANY's Subsidiaries) has not incurred any
liability for excise tax or penalty due to the Internal Revenue Service nor any
liability to the Pension Benefit Guaranty Corporation. The STOCKHOLDER further
represent that:

               (i) there have been no terminations, partial terminations or
        discontinuance of contributions to any such Qualified Plan intended to
        qualify under Section 401(a) of the Code without notice to and approval
        by the Internal Revenue Service;

               (ii) no such plan listed in Schedule 5.19 subject to the
        provisions of Title IV of ERISA has been terminated;

               (iii) there have been no "reportable events" (as that phrase is
        defined in Section 4043 of ERISA) with respect to any such plan listed
        in Schedule 5.19;

               (iv) COMPANY (including the COMPANY's Subsidiaries) has not
        incurred liability under Section 4062 of ERISA; and

               (v) No circumstances exist pursuant to which the COMPANY could
        have any direct or indirect liability whatsoever (including, but not
        limited to, any liability to any multiemployer plan or the PBGC under
        Title IV of ERISA or to the Internal Revenue Service for any excise tax
        or penalty, or being subject to any statutory lien to secure payment of
        any such liability) with respect to any plan now or heretofore
        maintained or contributed to by any entity other than the COMPANY that
        is, or at any time was, a member of a "controlled group" (as defined in
        Section 412(n)(6)(B) of the Code) that includes the COMPANY.

        5.21 CONFORMITY WITH LAW; LITIGATION. Except to the extent set forth on
Schedule 5.21 or 5.13, the COMPANY is not in violation of any law or regulation
or any order of any court or Federal, state, municipal or other governmental
department, commission, board, bureau, agency or instrumentality having
jurisdiction over any of them which would have a Material Adverse Effect; and
except to the extent set forth on Schedule 5.10 or 5.13, there are no material
claims, actions, suits

                                      -23-


or proceedings, pending or, to the knowledge of the COMPANY, threatened against
or affecting, the COMPANY, at law or in equity, or before or by any Federal,
state, municipal or other governmental department, commission, board, bureau,
agency or instrumentality having jurisdiction over any of them and no notice of
any claim, action, suit or proceeding, whether pending or threatened, has been
received. The COMPANY has conducted and is conducting its business in
substantial compliance with the requirements, standards, criteria and conditions
set forth in applicable Federal, state and local statutes, ordinances, permits,
licenses, orders, approvals, variances, rules and regulations, including all
such permits, licenses, orders and other governmental approvals set forth on
Schedules 5.12 and 5.13, and is not in violation of any of the foregoing which

        5.22 TAXES. COMPANY (including the COMPANY's Subsidiaries) has timely
filed all requisite federal, state and other tax returns or extension requests
for all fiscal periods ended on or before the Balance Sheet Date; and except as
set forth on Schedule 5.22, there are no examinations in progress or claims
against any of them for federal, state and other taxes (including penalties and
interest) for any period or periods prior to and including the Balance Sheet
Date and no notice of any claim for taxes, whether pending or threatened, has
been received. All tax, including interest and penalties (whether or not shown
on any tax return) owed by the COMPANY, any of the COMPANY's Subsidiaries, any
member of an affiliated or consolidated group which includes or included the
COMPANY or any of the COMPANY's Subsidiaries, or with respect to any payment
made or deemed made by the COMPANY or any of the COMPANY's Subsidiaries herein

that date. Copies of (i) any tax examinations, (ii) extensions of statutory
limitations and (iii) the federal and local income tax returns and franchise tax
returns of COMPANY (including the COMPANY Subsidiaries) for their last three (3)
fiscal years, or such shorter period of time as any of them shall have existed,
are attached hereto as Schedule 5.22. The

                                      -24-


STOCKHOLDER made valid elections under the provisions of Subchapter S of the
Code with respect to each Company and the COMPANY has not, within the past five
years, been taxed under the provisions of Subchapter C of the Code. The COMPANY
has a taxable year ended December 31 and has not made an election to retain a
fiscal year other than December 31 under Section 444 of the Code. The COMPANY's
methods of accounting have not changed in the past five years. The COMPANY is
not an investment company as defined in Section 351(e)(1) of the Code.

        5.23 NO VIOLATIONS. The COMPANY is not in violation of any Charter
Document. Neither the COMPANY nor, to the knowledge of the COMPANY, any other
party thereto, is in material default under any lease, instrument, agreement,
license, or permit set forth on Schedule 5.12, 5.13, 5.14, 5.15 or 5.16, or any
other material agreement to which it is a party or by which its properties are

of the name of any other party to such Material Document, and none of the

subject to the provisions of Section 7.8, such notification shall not relieve
either the COMPANY or the STOCKHOLDER of their respective obligations under this
Agreement, and, subject to the provisions of Section 7.8, at the sole option of
CSI, the truth and accuracy of any and all warranties and representations of the
COMPANY, or on behalf of the COMPANY and of STOCKHOLDER at the date of this

assurance of any kind, whether express or implied, oral or written, that a
Registration Statement will become effective or that the IPO pursuant thereto

at all; (ii) that neither CSI or any of its officers, directors, agents or
representatives nor any Underwriter shall have any liability to the COMPANY, the
STOCKHOLDER or any other person affiliated or associated with the COMPANY for
any failure of the Registration Statement to become effective, the IPO to occur
at a particular price or within a particular range of prices or to occur at all;
and (iii) that the decision of STOCKHOLDER to enter into this Agreement, or to
vote in favor of or consent to the proposed Merger, has been or will be made
independent of, and without reliance upon, any statements, opinions or other
communications, or due diligence investigations which have been or will be made
or performed by any prospective Underwriter, relative to CSI or the prospective
IPO.

discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of

amendment or supplement; and provided

Material Adverse Effect may be made unless a majority of the Founding Companies
consent to such amendment or supplement. For all purposes of this Agreement,
including without limitation for purposes of determining whether the conditions
set forth in Sections 8.1 and 9.1 have been fulfilled, the Schedules hereto
shall be deemed to be the Schedules as amended or supplemented pursuant to this

thereof. If CSI and a majority of the Founding Companies consent to such
amendment or supplement, which consent shall have been deemed given by CSI or
any Founding Company if no response is received within 24 hours following
receipt of notice of such amendment or supplement (or sooner if required by the
circumstances under which such consent is requested), but the COMPANY does not
give its consent (provided that consent shall be deemed given if any COMPANY
consents), the COMPANY may terminate this Agreement pursuant to Section 12.1(iv)
hereof. In the event that any COMPANY seeks to amend or supplement a Schedule
pursuant to this Section 7.8, and CSI and a majority of the Other Founding
Companies do not consent to such amendment or supplement, this Agreement shall
be deemed terminated by mutual consent as set forth in Section 12.1(i) hereof.

pursuant to this Section 7.8 and a majority of the Founding Companies do not
consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the
anticipated effectiveness of the Registration Statement.

shall use its best efforts to have the STOCKHOLDER released from any and all
guarantees on any indebtedness that he personally guaranteed and from any and
all pledges of assets that he pledged to secure such indebtedness for the
benefit of the COMPANY, with all such guarantees on indebtedness being assumed
by CSI. In the event that CSI cannot obtain such releases from the lenders of
any such guaranteed indebtedness on or prior to 120 days subsequent to the
Funding and Consummation Date, CSI shall pay off or otherwise refinance or
retire such indebtedness. From and after the Funding and Consummation Date and
until such time as all of such indebtedness is paid off, refinanced or retired,
CSI shall maintain unencumbered funds in amounts sufficient to provide for such
pay off, refinancing or retirement, provided that CSI may use such funds for
other purposes, in its sole discretion, with the prior written consent of each
STOCKHOLDER who has not as of that time been released from his or her guarantee
as described above and whose indebtedness as described above has not as of that
time been paid off, refinanced or retired.

        10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as
contemplated by this Agreement or the Registration Statement, after the Funding
and Consummation Date, CSI shall not and shall not permit any of its
subsidiaries to undertake any act that would jeopardize the tax-free status of
the organization, including without limitation:

               (a) the retirement or reacquisition, directly or indirectly, of
        all or part of the CSI Stock issued in connection with the transactions
        contemplated hereby; or

               (b) the entering into of financial arrangements for the benefit
        of the STOCKHOLDER.

        10.3   PREPARATION AND FILING OF TAX RETURNS.

               (i) The COMPANY shall, if possible, file or cause to be filed all
        separate Returns of any Acquired Party for all taxable periods that end
        on or before the Funding and Consummation Date. Notwithstanding the
        foregoing, the STOCKHOLDER shall file or

                                      -52-


        cause to be filed all separate federal income Tax Returns (and any State
        and local Tax Returns filed on the basis similar to that of S
        corporations under federal income Tax rules) of any Acquired Party for
        all taxable periods that end on or before the Funding and Consummation
        Date. The STOCKHOLDER shall pay or cause to be paid all Tax liabilities
        (in excess of all amounts already paid with respect thereto or properly
        accrued or reserved with respect thereto on the COMPANY Financial
        Statements) shown by such Returns to be due.

               (ii) CSI shall file or cause to be filed all separate Returns of,
        or that include, any Acquired Party for all taxable periods ending after
        the Funding and Consummation Date.

               (iii) Each party hereto shall, and shall cause its subsidiaries
        and affiliates to, provide to each of the other parties hereto such
        cooperation and information as any of them reasonably may request in
        filing any Return, amended Return or claim for refund, determining a
        liability for Taxes or a right to refund of Taxes or in conducting any
        audit or other proceeding in respect of Taxes. Such cooperation and
        information shall include providing copies of all relevant portions of
        relevant Returns, together with relevant accompanying schedules and
        relevant work papers, relevant documents relating to rulings or other
        determinations by Taxing Authorities and relevant records concerning the
        ownership and Tax basis of property, which such party may possess. Each
        party shall make its employees reasonably available on a mutually
        convenient basis at its cost to provide explanation of any documents or
        information so provided. Subject to the preceding sentence, each party
        required to file Returns pursuant to this Agreement shall bear all costs
        of filing such Returns.

               (iv) Each of the COMPANY, NEWCO, CSI and the STOCKHOLDER shall
        comply with the tax reporting requirements of Section 1.351-3 of the
        Treasury Regulations promulgated under the Code, and treat the
        transaction as a tax-free contribution under

                                      -53-


Section 351(a) of the Code subject to gain, if any, recognized on the receipt of
cash or other property under Section 351(b) of the Code.

        10.4 DIRECTORS. The persons named in the draft of the Registration
Statement shall be as directors and elected as officers of CSI, as and to the
extent set forth in the draft of the Registration Statement, promptly following
the Funding and Consummation Date. This provision shall not imply that the
STOCKHOLDERS have any power or duty to elect officers of CSI.

        10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation to provide
replacement plans that have the same terms and provisions as the existing plans,
provided, further, that any new health insurance plan shall provide for coverage
for preexisting conditions. On the Funding and Consummation Date, the employees
of each COMPANY will be the employees of the respective Surviving Corporation
(provided that this provision is for purposes of clarifying that the Merger, in
and of itself, will not have any impact on the employment status of any employee
and provided, further that this provision shall not in any way limit the
management rights of such Surviving Corporation or CSI to assess workforce needs
and make appropriate adjustments as necessary or desirable within their
discretion subject to applicable laws and collective bargaining agreements).

        10.6 DIVIDENDS. If the COMPANY is an S corporation, the COMPANY may pay
to each STOCKHOLDER as a dividend the full amount of his or her "accumulated
adjustments account" (as defined in Section 1368(e) of the Code) as of the
Balance Sheet Date, and may also pay to the STOCKHOLDERS as a dividend the full
amount of the COMPANY's earnings taxable to such STOCKHOLDERS for the period
after the Balance Sheet Date to the Funding and Consummation Date. If the
COMPANY is a C corporation, the COMPANY may pay to the STOCKHOLDERS as a
dividend the full amount of the COMPANY's earnings for the period after the
Balance Sheet Date

                                      -54-


to the Funding and Consummation Date. The COMPANY may borrow funds to the extent
necessary to make the payments contemplated by this Section 10.6 and to the
extent necessary to ensure that the COMPANY has cash on hand to adequately fund
operations on the Funding and Consummation Date.

11.     INDEMNIFICATION

        The STOCKHOLDER, CSI and NEWCO each make the following covenants that
are applicable to them, respectively:

        11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDER. The STOCKHOLDER
covenants and agrees that he will indemnify, defend, protect and hold harmless
CSI, NEWCO, the COMPANY and the Surviving Corporation at all times, from and
after the date of this Agreement until the Expiration Date, from and against all
claims, damages, actions, suits, proceedings, demands, assessments, adjustments,
costs and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by CSI, NEWCO, the
COMPANY or the Surviving Corporation as a result of or arising from (i) any
breach of the representations and warranties of the STOCKHOLDER or either
COMPANY set forth herein or on the schedules or certificates delivered in
connection herewith, (ii) any breach of any agreement on the part of the
STOCKHOLDER or either COMPANY under this Agreement, or (iii) any liability under
the 1933 Act, the 1934 Act or other Federal or state law or regulation, at
common law or otherwise, arising out of or based upon any untrue statement or
alleged untrue statement of a material fact relating to either COMPANY or the
STOCKHOLDER, and provided to CSI or its counsel by either COMPANY or the
STOCKHOLDER (but in the case of the STOCKHOLDER, only if such statement was
provided in writing) contained in the Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto, or
arising out of or based upon any omission or alleged omission to state therein a
material fact relating to either COMPANY or the STOCKHOLDER required to be
stated therein or necessary to make the statements therein

                                      -55-


not misleading, provided, however, that such indemnity shall not inure to the
benefit of CSI, NEWCO, the COMPANY or the Surviving Corporation to the extent
that such untrue statement (or alleged untrue statement) was made in, or
omission (or alleged omission) occurred in, any preliminary prospectus and the
STOCKHOLDER provided, in writing, corrected information to CSI counsel and to
CSI for inclusion in the final prospectus, and such information was not so
included or properly delivered.

        11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDER at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
STOCKHOLDER as a result of or arising from (i) any breach by CSI or NEWCO of
their representations and warranties set forth herein or on the schedules or
certificates attached hereto, (ii) any nonfulfillment of any agreement on the
part of CSI or NEWCO under this Agreement, (iii) any liabilities which the
STOCKHOLDER may incur due to CSI's or NEWCO's failure to be responsible for the
liabilities and obligations of the COMPANY as provided in Section 1 hereof
(except to the extent that CSI or NEWCO has claims against the STOCKHOLDER by
reason of such liabilities); or (iv) any liability under the 1933 Act, the 1934
Act or other Federal or state law or regulation, at common law or otherwise,
arising out of or based upon any untrue statement or alleged untrue statement of
a material fact relating to CSI, NEWCO or any of the Other Founding Companies
contained in any preliminary prospectus, the Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or arising out of or based upon any omission or alleged omission to
state therein a material fact relating to CSI or NEWCO or any of the Other
Founding Companies required to be stated therein or necessary to make the
statements therein not misleading.

                                      -56-


        11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified Party
of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or control. All Indemnified Parties shall use the same counsel, which
shall be the counsel selected by Indemnifying Party, provided that if counsel to
the Indemnifying Party shall have a conflict of interest that prevents counsel
for the Indemnifying Party from representing Indemnified Party, Indemnified
Party shall have the right to participate in such matter through counsel of its
own choosing and Indemnifying Party will reimburse the Indemnified Party for the
reasonable expenses of its counsel. After the Indemnifying Party has notified
the Indemnified Party of its intention to undertake to defend or settle any such
asserted liability, and for so long as the Indemnifying Party diligently pursues
such defense, the Indemnifying Party shall not be liable for any additional
legal expenses incurred by the Indemnified Party in connection with any defense
or settlement of such asserted liability, except (i) as set forth in the
preceding sentence and (ii) to the extent such

                                      -57-


participation is requested by the Indemnifying Party, in which event the
Indemnified Party shall be reimbursed by the Indemnifying Party for reasonable
additional legal expenses and out-of-pocket expenses. If the Indemnifying Party
desires to accept a final and complete settlement of any such Third Person claim
and the Indemnified Party refuses to consent to such settlement, then the
Indemnifying Party's liability under this Section with respect to such Third
Person claim shall be limited to the amount so offered in settlement by said
Third Person. Upon agreement as to such settlement between said Third Person and
the Indemnifying Party, the Indemnifying Party shall, in exchange for a complete
release from the Indemnified Party, promptly pay to the Indemnified Party the
amount agreed to in such settlement and the Indemnified Party shall, from that
moment on, bear full responsibility for any additional costs of defense which it
subsequently incurs with respect to such claim and all additional costs of
settlement or judgment. If the Indemnifying Party does not undertake to defend
such matter to which the Indemnified Party is entitled to indemnification
hereunder, or fails diligently to pursue such defense, the Indemnified Party may
undertake such defense through counsel of its choice, at the cost and expense of
the Indemnifying Party, and the Indemnified Party may settle such matter, and
the Indemnifying Party shall reimburse the Indemnified Party for the amount paid
in such settlement and any other liabilities or expenses incurred by the
Indemnified Party in connection therewith, provided, however, that under no
circumstances shall the Indemnified Party settle any Third Person claim without
the written consent of the Indemnifying Party, which consent shall not be
unreasonably withheld or delayed. All settlements hereunder shall effect a
complete release of the Indemnified Party, unless the Indemnified Party
otherwise agrees in writing. The parties hereto will make appropriate
adjustments for insurance proceeds in determining the amount of any
indemnification obligation under this Section.

        11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section
11 shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided

                                      -58-


that, nothing herein shall be construed to limit the right of a party, in a
proper case, to seek injunctive relief for a breach of this Agreement.

        11.5 LIMITATIONS ON INDEMNIFICATION. None of CSI, any NEWCO, any
Surviving Corporation nor any other persons or entities indemnified pursuant to
Section 11.1 or 11.2 shall assert any claim for indemnification hereunder
against the STOCKHOLDER until such time as, and solely to the extent that, the
aggregate of all claims which such persons may have against such the STOCKHOLDER
shall exceed the greater of 1.0% of the sum of the cash paid to STOCKHOLDER plus
the value of the CSI Stock delivered to STOCKHOLDER (calculated as provided in
this Section 11.5) or (b) $50,000 (the "Indemnification Threshold"). STOCKHOLDER
shall not assert any claim for indemnification hereunder against CSI or any
NEWCO until such time as, and solely to the extent that, the aggregate of all
claims which STOCKHOLDER may have against CSI or any or all NEWCOs shall exceed
$50,000.

        No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

        Notwithstanding any other term of this Agreement, no STOCKHOLDER shall
be liable under this Section 11 for an amount which exceeds the amount of
proceeds received by such STOCKHOLDER in connection with the Merger. For
purposes of calculating the value of the CSI Stock received by a STOCKHOLDER,
CSI Stock shall be valued at its initial public offering price as set forth in
the Registration Statement. It is hereby understood and agreed that a
STOCKHOLDER may satisfy an indemnification obligation through payment of a
combination of stock and cash in proportion equal to the proportion of stock and
cash received by such STOCKHOLDER in connection with the Merger, valued as
described immediately above.

12.     TERMINATION OF AGREEMENT

        12.1 TERMINATION. This Agreement may be terminated (it being understood
and agreed that, for purposes of this Section 12, the term "COMPANY" means both
of the COMPANIES which

                                      -59-


shall, for purposes of this Section 12, at any time prior to the Funding and
Consummation Date solely:

        (i) by mutual consent of the boards of directors of CSI and the COMPANY;

        (ii) by the STOCKHOLDER or the COMPANY (acting through its board of
directors), the one hand, or by CSI (acting through its board of directors), on
the other hand, if the transactions contemplated by this Agreement to take place
at the Closing shall not have been consummated by September 30, 1997, unless the
failure of such transactions to be consummated is due to the willful failure of
the party seeking to terminate this Agreement to perform any of its obligations
under this Agreement to the extent required to be performed by it prior to or on
the Funding and Consummation Date;

        (iii) by the STOCKHOLDER or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due and timely performance of any of the covenants or
agreements contained herein, and the curing of such default shall not have been
made on or before the Funding and Consummation Date or by the STOCKHOLDERS, or
the COMPANY, if the conditions set forth in Section 8 hereof have not been
satisfied or waived as of the Closing Date or the Funding and Consummation Date,
as applicable, or by CSI, if the conditions set forth in Section 9 hereof have
not been satisfied or waived as of the Closing Date or the Funding and
Consummation Date, as applicable;

        (iv)   pursuant to Section 7.8 hereof; or

        (v)    pursuant to Section 4 hereof.

        12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

                                      -60-


13.     NONCOMPETITION

        13.1 PROHIBITED ACTIVITIES. The STOCKHOLDER will not, for a period of
five (5) years following the Funding and Consummation Date, for any reason
whatsoever, directly or indirectly, for himself or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

        (i) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial capacity, whether as an employee, independent
contractor, consultant or advisor, or as a sales representative, in any heating,
ventilating or air conditioning services business in direct competition with CSI
or any of the subsidiaries thereof, within 100 miles of where the COMPANY or any
of its subsidiaries conducted business prior to the effectiveness of the Merger
(the "Territory");

        (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the subsidiaries
thereof), provided that the STOCKHOLDER shall be permitted to call upon and hire
any member of his immediate family;

        (iii) call upon any person or entity which is, at that time, or which
has been, within one (1) year prior to the Funding and Consummation Date, a
customer of CSI (including the subsidiaries thereof), of the COMPANY or of any
of the Other Founding Companies within the Territory for the purpose of
soliciting or selling products or services in direct competition with CSI within
the Territory;

        (iv) call upon any prospective acquisition candidate, on the
STOCKHOLDER'S own behalf or on behalf of any competitor in the heating,
ventilation or air conditioning services business, which candidate, to the
actual knowledge of the STOCKHOLDER after due inquiry, was called upon by CSI
(including the subsidiaries thereof) or for which, to the actual knowledge of
such

                                      -61-


STOCKHOLDER after due inquiry, CSI (or any subsidiary thereof) made an
acquisition analysis, for the purpose of acquiring such entity; or

        (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

        Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit the STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

        13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to CSI for which it would
have no other adequate remedy, the STOCKHOLDER agrees that the foregoing
covenant may be enforced by CSI in the event of breach by the STOCKHOLDER, by
injunctions and restraining orders.

        13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDER in light of the activities and business of CSI (including the
subsidiaries thereof) on the date of the execution of this Agreement and the
current plans of CSI.

        13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

                                      -62-


        13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of the STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of the STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which the
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

        13.6 MATERIALITY. The COMPANY and the STOCKHOLDER hereby agree that this
covenant is a material and substantial part of this transaction.

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

        14.1 STOCKHOLDER. The STOCKHOLDER recognizes and acknowledges that he
had in the past, currently has, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. The STOCKHOLDER agrees that he
will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except (a) to authorized representatives of CSI, (b) following the Closing, such
information may be disclosed by the STOCKHOLDER as is required in the course of
performing his duties for CSI or the Surviving Corporation and (c) to counsel
and other advisers, provided that such advisers (other than counsel) agree to
the confidentiality provisions of this Section 14.1, unless (i) such information
becomes

                                      -63-


known to the public generally through no fault of the STOCKHOLDER, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), the STOCKHOLDER shall, if possible, give prior written notice
thereof to CSI and provide CSI with the opportunity to contest such disclosure,
or (iii) the disclosing party reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party. In the event of a breach or threatened breach by the STOCKHOLDER of the
provisions of this Section, CSI shall be entitled to an injunction restraining
the STOCKHOLDER from disclosing, in whole or in part, such confidential
information. Nothing herein shall be construed as prohibiting CSI from pursuing
any other available remedy for such breach or threatened breach, including the
recovery of damages. In the event the transactions contemplated by this
Agreement are not consummated, STOCKHOLDER shall have none of the
above-mentioned restrictions on their ability to disseminate confidential
information with respect to the COMPANY.

        14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they
had in the past and currently have access to certain confidential information of
the COMPANY, such as operational policies, and pricing and cost policies that
are valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, (c) to the Other Founding Companies and their representatives pursuant to
Section 7.1(a), unless (i) such information becomes known to the public
generally through no fault of CSI or NEWCO, (ii) disclosure is required by law
or the order of any governmental authority under color of law, provided, that
prior to disclosing any information pursuant to this clause (ii), CSI and NEWCO
shall, if possible, give prior written notice thereof to the COMPANY and the

                                      -64-


STOCKHOLDER and provide the COMPANY and the STOCKHOLDER with the opportunity to
contest such disclosure, or (iii) the disclosing party reasonably believes that
such disclosure is required in connection with the defense of a lawsuit against
the disclosing party, and (d) to the public to the extent necessary or advisable
in connection with the filing of the Registration Statement and the IPO and the
securities laws applicable thereto and to the operation of CSI as a publicly
held entity after the IPO. In the event of a breach or threatened breach by CSI
or NEWCO of the provisions of this Section, the COMPANY and the STOCKHOLDER
shall be entitled to an injunction restraining CSI and NEWCO from disclosing, in
whole or in part, such confidential information. Nothing herein shall be
construed as prohibiting the COMPANY and the STOCKHOLDER from pursuing any other
available remedy for such breach or threatened breach, including the recovery of
damages.

        14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

        14.4 SURVIVAL. The obligations of the parties under this Article 14
shall survive the termination of this Agreement for a period of five years from
the Funding and Consummation Date.

15.     TRANSFER RESTRICTIONS

        15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDER or family members, the trustees of
which so agree), for a period of one year from the Closing, except pursuant to
Section 17 hereof, the STOCKHOLDER shall not sell, assign, exchange, transfer,
encumber, pledge, distribute, appoint, or otherwise dispose of any shares of CSI
Stock as described in Section 3.1 received by the STOCKHOLDER in the Merger. The
certificates

                                      -65-


evidencing the CSI Stock delivered to the STOCKHOLDER pursuant to Section 3 of
this Agreement will bear a legend substantially in the form set forth below and
containing such other information as CSI may deem necessary or appropriate:

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED,
TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED
OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT
OR OTHER DISPOSITION PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE
WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE
THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT)
AFTER THE DATE SPECIFIED ABOVE.

16.     FEDERAL SECURITIES ACT REPRESENTATIONS

        16.1 COMPLIANCE WITH LAW. The STOCKHOLDER acknowledges that the shares
of CSI Stock to be delivered to the STOCKHOLDER pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and therefore may not be resold without compliance with the Act. The
CSI Stock to be acquired by the STOCKHOLDER pursuant to this Agreement is being
acquired solely for his own account, for investment purposes only, and with no
present intention of distributing, selling or otherwise disposing of it in
connection with a distribution. The STOCKHOLDER covenants, warrants and
represents that none of the shares of CSI Stock issued to the STOCKHOLDER will
be offered, sold, assigned, pledged, hypothecated, transferred or otherwise
disposed of except after full compliance with all of the

                                      -66-


applicable provisions of the Act and the rules and regulations of the SEC. All
the CSI Stock shall bear the following legend in addition to the legend required
under Section 15 of this Agreement:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

        16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDER is able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and has such
knowledge and experience in financial and business matters that he is capable of
evaluating the merits and risks of the proposed investment in the CSI Stock. The
STOCKHOLDER has had an adequate opportunity to ask questions and receive answers
from the officers of CSI concerning any and all matters relating to the
transactions described herein including, without limitation, the background and
experience of the current and proposed officers and directors of CSI, the plans
for the operations of the business of CSI, the business, operations and
financial condition of the Founding Companies other than the COMPANY, and any
plans for additional acquisitions and the like. The STOCKHOLDER has asked any
and all questions in the nature described in the preceding sentence and all
questions have been answered to his satisfaction.

17.     REGISTRATION RIGHTS

        17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
the STOCKHOLDER prompt written notice of its intent to do so. Upon the written
request of

                                      -67-


the STOCKHOLDER given within 30 days after receipt of such notice, CSI shall
cause to be included in such registration all of the CSI Stock issued to the
STOCKHOLDER pursuant to this Agreement (including any stock issued as (or
issuable upon the conversion or exchange of any convertible security, warrant,
right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) which the STOCKHOLDER requests, provided that CSI shall have the right to
reduce the number of shares included in such registration to the extent that
inclusion of such shares could, in the opinion of tax counsel to CSI or its
independent auditors, jeopardize the status of the transactions contemplated
hereby and by the Registration Statement as a tax-free organization. In
addition, if CSI is advised in writing in good faith by any managing underwriter
of an underwritten offering of the securities being offered pursuant to any
registration statement under this Section 17.1 that the number of shares to be
sold by persons other than CSI is greater than the number of such shares which
can be offered without adversely affecting the offering, CSI may reduce pro rata
the number of shares offered for the accounts of such persons (based upon the
number of shares held by such person) to a number deemed satisfactory by such
managing underwriter, provided, that, for each such offering made by CSI after
the IPO, such reduction shall be made first by reducing the number of shares to
be sold by persons other than CSI, the STOCKHOLDER and the stockholders of the
Other Founding Companies (collectively, the STOCKHOLDER and the stockholders of
the other Founding Companies being referred to herein as the "Founding
Stockholders"), and thereafter, if a further reduction is required, by reducing
the number of shares to be sold by the Founding Stockholders.

        17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year
after the Closing and prior to the date three years after the Closing, the
holders of a majority of the shares of CSI Stock issued to the Founding
Stockholders pursuant to this Agreement and the Other Agreements which have not
been previously registered or sold and which are not entitled to be sold under
Rule 144(k) (or any similar or successor provision) promulgated under the 1933
Act may request in writing that CSI file a registration statement under the 1933
Act covering the registration of the

                                      -68-


shares of CSI Stock issued to the STOCKHOLDER pursuant to this Agreement and the
Other Agreements (including any stock issued as (or issuable upon the conversion
or exchange of any convertible security, warrant, right or other security which
is issued by CSI as) a dividend or other distribution with respect to, or in
exchange for, or in replacement of such CSI Stock) then held by such Founding
Stockholders (a "Demand Registration"). Within ten (10) days of the receipt of
such request, CSI shall give written notice of such request to all other
Founding Stockholders and shall, as soon as practicable but in no event later
than 45 days after notice from the STOCKHOLDER, file and use its best efforts to
cause to become effective a registration statement covering all such shares. CSI
shall be obligated to effect only one Demand Registration for all Founding
Stockholders and will keep such Demand Registration current and effective for
not less than 90 days (or such shorter period as is required to sell all of the
shares registered thereby).

        Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the date on which CSI
would otherwise be required to make such filing pursuant to the foregoing
paragraph.

        If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective date of such registration unless CSI is no longer proceeding
diligently to effect such registration; provided that CSI shall provide the
Founding Stockholders the right to participate in such public offering pursuant
to, and subject to, Section 17.1 hereof.

        17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with
the registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection

                                      -69-


with registrations under Sections 17.1 and 17.2, CSI shall (i) use its best
efforts to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

        17.4 UNDERWRITING AGREEMENT. In connection with each registration
pursuant to Sections 17.1 and 17.2 covering an underwritten registered offering,
CSI and each participating holder agree to enter into a written agreement with
the managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
managing underwriters and companies of CSI's size and investment stature,
including indemnification.

        17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by the STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to the STOCKHOLDER.

        17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

               (i) make and keep public information regarding CSI available as
        those terms are understood and defined in Rule 144 under the 1933 Act
        for a period of four years beginning 90 days following the effective
        date of the Registration Statement;

                                      -70-


               (ii) file with the SEC in a timely manner all reports and other
        documents required of CSI under the 1933 Act and the 1934 Act at any
        time after it has become subject to such reporting requirements; and

               (iii) so long as a STOCKHOLDER owns any restricted CSI Common
        Stock, furnish to each STOCKHOLDER forthwith upon written request a
        written statement by CSI as to its compliance with the reporting
        requirements of Rule 144 (at any time from and after 90 days following
        the effective date of the Registration Statement, and of the 1933 Act
        and the 1934 Act (at any time after it has become subject to such
        reporting requirements), a copy of the most recent annual or quarterly
        report of CSI, and such other reports and documents so filed as a
        STOCKHOLDER may reasonably request in availing itself of any rule or
        regulation of the SEC allowing a STOCKHOLDER to sell any such shares
        without registration.

        18.    GENERAL

        18.1 COOPERATION. Each COMPANY, STOCKHOLDER, CSI and NEWCO shall each
deliver or cause to be delivered to the other on the Funding and Consummation
Date, and at such other times and places as shall be reasonably agreed to, such
additional instruments as the other may reasonably request for the purpose of
carrying out this Agreement. Each COMPANY will cooperate and use its reasonable
efforts to have the present officers, directors and employees of such COMPANY
cooperate with CSI on and after the Funding and Consummation Date in furnishing
information, evidence, testimony and other assistance in connection with any tax
return filing obligations, actions, proceedings, arrangements or disputes of any
nature with respect to matters pertaining to all periods prior to the Funding
and Consummation Date.

        18.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law) and shall be
binding upon and shall inure to the benefit

                                      -71-


of the parties hereto, the successors of CSI, and the heirs and legal
representatives of the STOCKHOLDER.

        18.3 ENTIRE AGREEMENT. This Agreement (including the schedules, exhibits
and annexes attached hereto) and the documents delivered pursuant hereto
constitute the entire agreement and understanding among the STOCKHOLDER, each
COMPANY, each NEWCO and CSI and supersede any prior agreement and understanding
relating to the subject matter of this Agreement. This Agreement, upon
execution, constitutes a valid and binding agreement of the parties hereto
enforceable in accordance with its terms and may be modified or amended only by
a written instrument executed by the STOCKHOLDER, each COMPANY, each NEWCO and
CSI, acting through their respective officers or trustees, duly authorized by
their respective Boards of Directors. Any disclosure made on any Schedule
delivered pursuant hereto shall be deemed to have been disclosed for purposes of
any other Schedule required hereby, provided that each COMPANY shall make a good
faith effort to cross reference disclosure, as necessary or advisable, between
related Schedules.

        18.4 COUNTERPARTS. This Agreement may be executed simultaneously in two
(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

        18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each
party represents and warrants that it employed no broker or agent in connection
with this transaction and agrees to indemnify the other parties hereto against
all loss, cost, damages or expense arising out of claims for fees or commission
of brokers employed or alleged to have been employed by such indemnifying party.

        18.6 EXPENSES. Whether or not the transactions herein contemplated shall
be consummated, CSI will pay the fees, expenses and disbursements of CSI and its
agents, representatives, accountants and counsel incurred in connection with the
subject matter of this Agreement and any amendments thereto, including all costs

      being subject to any statutory lien to secure payment of any such
      liability) with respect to any plan now or heretofore maintained or
      contributed to by any entity other than the COMPANY that is, or at any

agreements are listed on Schedule 7.6 and copies thereof shall be attached
thereto.

      7.7 NOTIFICATION OF CERTAIN MATTERS. The STOCKHOLDERS and the COMPANY
shall give prompt notice to CSI of (i) the occurrence or non-occurrence of any
event the occurrence or non-occurrence of which would be likely to cause any
representation or warranty of the COMPANY or the STOCKHOLDERS contained herein
to be untrue or inaccurate in any material respect at or prior to the Closing
and (ii) any material failure of any STOCKHOLDER or the COMPANY to comply with
or satisfy any covenant, condition or agreement to be complied with or satisfied
by such person hereunder. CSI and NEWCO shall give prompt notice to the COMPANY
of (i) the occurrence or non-occurrence of any event the occurrence or
non-occurrence of which would be likely to cause any representation or warranty
of CSI or NEWCO contained herein to be untrue or inaccurate in any material
respect at or prior to the Closing and (ii) any material failure of CSI or NEWCO
to comply with or satisfy any covenant, condition or agreement to be complied
with or satisfied by it hereunder. The delivery of any notice pursuant to this

the party receiving such notice.

      7.8 AMENDMENT OF SCHEDULES. Each party hereto agrees that, with respect to
the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have

                                    -40-

been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the COMPANY that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless CSI and
a majority of the Founding Companies other than the COMPANY consent to such
amendment or supplement; and provided further, that no amendment or supplement
to a Schedule prepared by CSI or NEWCO that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless a
majority of the Founding Companies consent to such amendment or supplement. For
all purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other
Founding Companies seeks to amend or supplement a Schedule pursuant to Section
7.8 of one of the Other Agreements, and such amendment or supplement constitutes
or reflects an event or occurrence that would have a Material Adverse Effect on
such Other Founding Company, CSI shall give the COMPANY notice promptly after it
has knowledge thereof. If CSI and a majority of the Founding Companies consent
to such amendment or supplement, which consent shall have been deemed given by
CSI or any Founding Company if no response is received within 24 hours following
receipt of notice of such amendment or supplement (or sooner if required by the
circumstances under which such consent is requested), but the COMPANY does not
give its consent, the COMPANY may terminate this Agreement pursuant to Section
12.1(iv) hereof. In the event that the COMPANY seeks to amend or supplement a
Schedule pursuant to this Section 7.8, and CSI and a majority of the Other
Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. In the event that CSI or NEWCO seeks to amend or supplement a
Schedule pursuant to this Section 7.8 and a majority of the Founding Companies
do not consent to such amendment or supplement, this

                                    -41-

Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. No party to this Agreement shall be liable to any other party if
this Agreement shall be terminated pursuant to the provisions of this Section
7.8. No amendment of or supplement to a Schedule shall be made later than 24
hours prior to the anticipated effectiveness of the Registration Statement.

      7.9 COOPERATION IN PREPARATION OF REGISTRATION STATEMENT. The COMPANY and
STOCKHOLDERS shall furnish or cause to be furnished to CSI and the Underwriters
all of the information concerning the COMPANY and the STOCKHOLDERS required for
inclusion in, and will cooperate with CSI and the Underwriters in the
preparation of, the Registration Statement and the prospectus included therein
(including audited and unaudited financial statements, prepared in accordance
with generally accepted accounting principles, in form suitable for inclusion in
the Registration Statement). The COMPANY and the STOCKHOLDERS agree promptly to
advise CSI if at any time during the period in which a prospectus relating to
the offering is required to be delivered under the Securities Act, any
information contained in the prospectus concerning the COMPANY or the
STOCKHOLDERS becomes incorrect or incomplete in any material respect, and to
provide the information needed to correct such inaccuracy. Insofar as the
information relates solely to the COMPANY or the STOCKHOLDERS, the COMPANY
represents and warrants as to such information with respect to itself, and each
Stockholder represents and warrants, as to such information with respect to the
COMPANY and himself or herself, that the Registration Statement will not include
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading.

      7.10 FINAL FINANCIAL STATEMENTS. The COMPANY shall provide prior to the
Funding and Consummation Date, and CSI shall have had sufficient time to review
the unaudited consolidated balance sheets of the COMPANY as of the end of all
fiscal quarters following the Balance Sheet Date, and the unaudited consolidated
statement of income, cash flows and retained earnings of the COMPANY for all
fiscal quarters ended after the Balance Sheet Date, disclosing no material
adverse change in the financial condition of the COMPANY or the results of its
operations from the financial

                                    -42-

statements as of the Balance Sheet Date. Such financial statements shall have
been prepared in accordance with generally accepted accounting principles
applied on a consistent basis throughout the periods indicated (except as noted
therein). Except as noted in such financial statements, all of such financial
statements will present fairly the results of operations of the COMPANY for the
periods indicated therein.

      7.11 FURTHER ASSURANCES. The parties hereto agree to execute and deliver,
or cause to be executed and delivered, such further instruments or documents or
take such other action as may be reasonably necessary or convenient to carry out
the transactions contemplated hereby.

      7.12 AUTHORIZED CAPITAL. CSI shall maintain its authorized capital stock
as set forth in the Registration Statement filed with the SEC except for such
changes in authorized capital stock as are made to respond to comments made by
the SEC or requirements of any exchange or automated trading system for which
application is made to register the CSI Stock.

      7.13 COMPLIANCE WITH THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF
1976 (THE "HART-SCOTT ACT"). All parties to this Agreement hereby recognize that
one or more filings under the Hart-Scott Act may be required in connection with
the transactions contemplated herein. If it is determined by the parties to this
Agreement that filings under the Hart-Scott Act are required, then: (i) each of
the parties hereto agrees to cooperate and use its best efforts to comply with
the Hart-Scott Act, (ii) such compliance by the STOCKHOLDERS and the COMPANY
shall be deemed a condition precedent in addition to the conditions precedent
set forth in Section 9 of this Agreement, and such compliance by CSI and NEWCO
shall be deemed a condition precedent in addition to the conditions precedent
set forth in Section 8 of this Agreement, and (iii) the parties agree to
cooperate and use their best efforts to cause all filings required under the
Hart-Scott Act to be made. If filings under the Hart-Scott Act are required, the
costs and expenses thereof (including filing fees) shall be borne by CSI.

      information shall include providing copies of all relevant portions of
      relevant Returns, together with relevant accompanying schedules and
      relevant work papers, relevant documents relating to rulings or other
      determinations by Taxing Authorities and relevant records concerning the

      party shall make its employees reasonably available on a mutually
      convenient basis at its cost to provide explanation of any documents or
      information so provided. Subject to the preceding sentence, each party
      required to file Returns pursuant to this Agreement shall bear all costs
      of filing such Returns.

            (iv) Each of the COMPANY, NEWCO, CSI and each STOCKHOLDER shall
      comply with the tax reporting requirements of Section 1.351-3 of the
      Treasury Regulations promulgated under the Code, and treat the transaction
      as a tax-free contribution under Section 351(a) of the Code subject to
      gain, if any, recognized on the receipt of cash or other property under
      Section 351(b) of the Code. 10.4 DIRECTORS. The persons named in the draft
      of the Registration Statement (including Michael Nothum, Jr.) shall be
      appointed as directors and elected as officers of CSI, as and to the
      extent set forth in the draft of the Registration Statement, promptly
      following the Funding and Consummation Date. This provision shall not
      imply that the STOCKHOLDERS have any power or duty to elect officers of
      CSI.

      10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in

                                    -51-

effect at the COMPANY until such time as CSI is able to replace such plan with a
plan that is applicable to CSI and all of its then existing subsidiaries,
provided that CSI shall have no obligation to provide replacement plans that
have the same terms and provisions as the existing plans, provided, further,
that any new health insurance plan shall provide for coverage for preexisting
conditions. On the Funding and Consummation Date, the employees of the COMPANY
will be the employees of the Surviving Corporation (provided that this provision
is for purposes of clarifying that the Merger, in and of itself, will not have
any impact on the employment status of any employee and provided, further that
this provision shall not in any way limit the management rights of the Surviving
Corporation or CSI to assess workforce needs and make appropriate adjustments as
necessary or desirable within their discretion subject to applicable laws and
collective bargaining agreements).

      10.6 DIVIDENDS. If the COMPANY is an S corporation, the COMPANY may pay to
each STOCKHOLDER as a dividend the full amount of his or her "accumulated
adjustments account" (as defined in Section 1368(e) of the Code) as of the
Balance Sheet Date, and may also pay to the STOCKHOLDERS as a dividend the full
amount of the COMPANY's earnings taxable to such STOCKHOLDERS for the period
after the Balance Sheet Date to the Funding and Consummation Date. If the
COMPANY is a C corporation, the COMPANY may pay to the STOCKHOLDERS as a
dividend the full amount of the COMPANY's earnings for the period after the
Balance Sheet Date to the Funding and Consummation Date. The COMPANY may borrow
funds to the extent necessary to make the payments contemplated by this Section
10.6 and to the extent necessary to ensure that the COMPANY has cash on hand to
adequately fund operations on the Funding and Consummation Date.

11.   INDEMNIFICATION

      The STOCKHOLDERS, CSI and NEWCO each make the following covenants that are
applicable to them, respectively:

      11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDERS. The STOCKHOLDERS
covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless

                                    -52-

CSI, NEWCO, the COMPANY and the Surviving Corporation at all times, from and
after the date of this Agreement until the Expiration Date, from and against all
claims, damages, actions, suits, proceedings, demands, assessments, adjustments,
costs and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by CSI, NEWCO, the
COMPANY or the Surviving Corporation as a result of or arising from (i) any
breach of the representations and warranties of the STOCKHOLDERS or the COMPANY
set forth herein or on the schedules or certificates delivered in connection
herewith, (ii) any breach of any agreement on the part of the STOCKHOLDERS or
the COMPANY under this Agreement, or (iii) any liability under the 1933 Act, the
1934 Act or other Federal or state law or regulation, at common law or
otherwise, arising out of or based upon any untrue statement or alleged untrue
statement of a material fact relating to the COMPANY or the STOCKHOLDERS, and
provided to CSI or its counsel by the COMPANY or the STOCKHOLDERS (but in the
case of the STOCKHOLDERS, only if such statement was provided in writing)
contained in the Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or arising out of or
based upon any omission or alleged omission to state therein a material fact
relating to the COMPANY or the STOCKHOLDERS required to be stated therein or
necessary to make the statements therein not misleading, provided, however, that
such indemnity shall not inure to the benefit of CSI, NEWCO, the COMPANY or the
Surviving Corporation to the extent that such untrue statement (or alleged
untrue statement) was made in, or omission (or alleged omission) occurred in,
any preliminary prospectus and the STOCKHOLDERS provided, in writing, corrected
information to CSI counsel and to CSI for inclusion in the final prospectus, and
such information was not so included or properly delivered, and provided
further, that no STOCKHOLDER shall be liable for any indemnification obligation
pursuant to this Section 11.1 to the extent attributable to a breach of any
representation, warranty or agreement made herein individually by any other
STOCKHOLDER.

      11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDERS at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits,

                                    -53-

proceedings, demands, assessments, adjustments, costs and expenses (including
specifically, but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by the STOCKHOLDERS as a result of or arising from (i)
any breach by CSI or NEWCO of their representations and warranties set forth
herein or on the schedules or certificates attached hereto, (ii) any
nonfulfillment of any agreement on the part of CSI or NEWCO under this
Agreement, (iii) any liabilities which the STOCKHOLDERS may incur due to CSI's
or NEWCO's failure to be responsible for the liabilities and obligations of the
COMPANY as provided in Section 1 hereof (except to the extent that CSI or NEWCO
has claims against the STOCKHOLDERS by reason of such liabilities); or (iv) any
liability under the 1933 Act, the 1934 Act or other Federal or state law or
regulation, at common law or otherwise, arising out of or based upon any untrue
statement or alleged untrue statement of a material fact relating to CSI, NEWCO
or any of the Other Founding Companies contained in any preliminary prospectus,
the Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to CSI or
NEWCO or any of the Other Founding Companies required to be stated therein or
necessary to make the statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has knowledge of any claim by a
person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party.

                                    -54-

If the Indemnifying Party undertakes to defend or settle, it shall promptly
notify the Indemnified Party of its intention to do so, and the Indemnified
Party shall cooperate with the Indemnifying Party and its counsel in the defense
thereof and in any settlement thereof. Such cooperation shall include, but shall
not be limited to, furnishing the Indemnifying Party with any books, records or
information reasonably requested by the Indemnifying Party that are in the
Indemnified Party's possession or control. All Indemnified Parties shall use the
same counsel, which shall be the counsel selected by Indemnifying Party,
provided that if counsel to the Indemnifying Party shall have a conflict of
interest that prevents counsel for the Indemnifying Party from representing
Indemnified Party, Indemnified Party shall have the right to participate in such
matter through counsel of its own choosing and Indemnifying Party will reimburse
the Indemnified Party for the reasonable expenses of its counsel. After the
Indemnifying Party has notified the Indemnified Party of its intention to
undertake to defend or settle any such asserted liability, and for so long as
the Indemnifying Party diligently pursues such defense, the Indemnifying Party
shall not be liable for any additional legal expenses incurred by the
Indemnified Party in connection with any defense or settlement of such asserted
liability, except (i) as set forth in the preceding sentence and (ii) to the
extent such participation is requested by the Indemnifying Party, in which event
the Indemnified Party shall be reimbursed by the Indemnifying Party for
reasonable additional legal expenses and out-of-pocket expenses. If the
Indemnifying Party desires to accept a final and complete settlement of any such
Third Person claim and the Indemnified Party refuses to consent to such
settlement, then the Indemnifying Party's liability under this Section with
respect to such Third Person claim shall be limited to the amount so offered in
settlement by said Third Person. Upon agreement as to such settlement between
said Third Person and the Indemnifying Party, the Indemnifying Party shall, in
exchange for a complete release from the Indemnified Party, promptly pay to the
Indemnified Party the amount agreed to in such settlement and the Indemnified
Party shall, from that moment on, bear full responsibility for any additional
costs of defense which it subsequently incurs with respect to such claim and all
additional costs of settlement or judgment. If the Indemnifying Party does not
undertake to defend such matter to which the Indemnified Party is entitled to
indemnification

                                    -55-

hereunder, or fails diligently to pursue such defense, the Indemnified Party may
undertake such defense through counsel of its choice, at the cost and expense of
the Indemnifying Party, and the Indemnified Party may settle such matter, and
the Indemnifying Party shall reimburse the Indemnified Party for the amount paid
in such settlement and any other liabilities or expenses incurred by the
Indemnified Party in connection therewith, provided, however, that under no
circumstances shall the Indemnified Party settle any Third Person claim without
the written consent of the Indemnifying Party, which consent shall not be
unreasonably withheld or delayed. All settlements hereunder shall effect a
complete release of the Indemnified Party, unless the Indemnified Party
otherwise agrees in writing. The parties hereto will make appropriate
adjustments for insurance proceeds in determining the amount of any
indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section 11
shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

      11.5 LIMITATIONS ON INDEMNIFICATION. CSI, NEWCO, the Surviving Corporation
and the other persons or entities indemnified pursuant to Section 11.1 or 11.2
shall not assert any claim for indemnification hereunder against the
STOCKHOLDERS until such time as, and solely to the extent that, the aggregate of
all claims which such persons may have against such the STOCKHOLDERS shall
exceed the greater of (a) 1.0% of the sum of the cash paid to STOCKHOLDERS plus
the value of the CSI Stock delivered to STOCKHOLDERS (calculated as provided in
this Section 11.5) or (b) $50,000 (the "Indemnification Threshold").
STOCKHOLDERS shall not assert any claim for indemnification hereunder against
CSI or NEWCO until such time as, and solely to the extent that, the aggregate of
all claims which STOCKHOLDERS may have against CSI or NEWCO shall exceed
$50,000.

                                    -56-

      No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

      Notwithstanding any other term of this Agreement, no STOCKHOLDER shall be
liable under this Section 11 for an amount which exceeds the amount of proceeds
received by such STOCKHOLDER in connection with the Merger. For purposes of
calculating the value of the CSI Stock received by a STOCKHOLDER, CSI Stock
shall be valued at its initial public offering price as set forth in the
Registration Statement. It is hereby understood and agreed that a STOCKHOLDER
may satisfy an indemnification obligation through payment of a combination of
stock and cash in proportion equal to the proportion of stock and cash received
by such STOCKHOLDER in connection with the Merger, valued as described
immediately above.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION.This Agreement may be terminated at any time prior to the
Funding and Consummation Date solely:

      (i)   by mutual consent of the boards of directors of CSI and the COMPANY;

      (ii) by the STOCKHOLDERS or the COMPANY (acting through its board of
directors), on the one hand, or by CSI (acting through its board of directors),
on the other hand, if the transactions contemplated by this Agreement to take
place at the Closing shall not have been consummated by September 30, 1997,
unless the failure of such transactions to be consummated is due to the willful
failure of the party seeking to terminate this Agreement to perform any of its
obligations under this Agreement to the extent required to be performed by it
prior to or on the Funding and Consummation Date;

      (iii) by the STOCKHOLDERS or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due and timely performance of any of the covenants or
agreements contained herein, and the curing of such default shall not have been
made on or before the Funding and Consummation Date or by the STOCKHOLDERS or
the COMPANY, if the conditions set forth in Section 8 hereof have not been

                                    -57-

satisfied or waived as of the Closing Date or the Funding and Consummation Date,
as applicable, or by CSI, if the conditions set forth in Section 9 hereof have
not been satisfied or waived as of the Closing Date or the Funding and
Consummation Date, as applicable;

      (iv)  pursuant to Section 7.8 hereof; or

      (v)   pursuant to Section 4 hereof.

      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. The STOCKHOLDERS will not, for a period of
five (5) years following the Funding and Consummation Date, for any reason
whatsoever, directly or indirectly, for themselves or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

      (i) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial capacity, whether as an employee, independent
contractor, consultant or advisor, or as a sales representative, in any heating,
ventilating or air conditioning services business in direct competition with CSI
or any of the subsidiaries thereof, within 100 miles of where the COMPANY or any
of its subsidiaries conducted business prior to the effectiveness of the Merger
(the "Territory");

      (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the subsidiaries
thereof), provided that each STOCKHOLDER shall be permitted to call upon and
hire any member of his or her immediate family;

                                    -58-

      (iii) call upon any person or entity which is, at that time, or which has
been, within one (1) year prior to the Funding and Consummation Date, a customer
of CSI (including the subsidiaries thereof), of the COMPANY or of any of the
Other Founding Companies within the Territory for the purpose of soliciting or
selling products or services in direct competition with CSI within the
Territory;

      (iv) call upon any prospective acquisition candidate, on any STOCKHOLDER's
own behalf or on behalf of any competitor in the heating, ventilation or air
conditioning services business, which candidate, to the actual knowledge of such
STOCKHOLDER after due inquiry, was called upon by CSI (including the
subsidiaries thereof) or for which, to the actual knowledge of such STOCKHOLDER
after due inquiry, CSI (or any subsidiary thereof) made an acquisition analysis,
for the purpose of acquiring such entity; or

      (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to CSI for which it would
have no other adequate remedy, each STOCKHOLDER agrees that the foregoing
covenant may be enforced by CSI in the event of breach by such STOCKHOLDER, by
injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDERS in light of the activities

                                    -59-

and business of CSI (including the subsidiaries thereof) on the date of the
execution of this Agreement and the current plans of CSI.

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of each STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which such
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

      13.6 MATERIALITY. The COMPANY and the STOCKHOLDERS hereby agree that this
covenant is a material and substantial part of this transaction.

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1  STOCKHOLDERS. The STOCKHOLDERS recognize and acknowledge that they

had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the

                                    -60-

COMPANY's, the Other Founding Companies' and/or CSI's respective businesses. The
STOCKHOLDERS agree that they will not disclose such confidential information to
any person, firm, corporation, association or other entity for any purpose or
reason whatsoever, except (a) to authorized representatives of CSI, (b)
following the Closing, such information may be disclosed by the STOCKHOLDERS as
is required in the course of performing their duties for CSI or the Surviving
Corporation and (c) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, unless (i) such information becomes known to the public generally through
no fault of the STOCKHOLDERS, (ii) disclosure is required by law or the order of
any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii), the STOCKHOLDERS shall,
if possible, give prior written notice thereof to CSI and provide CSI with the
opportunity to contest such disclosure, or (iii) the disclosing party reasonably
believes that such disclosure is required in connection with the defense of a
lawsuit against the disclosing party. In the event of a breach or threatened
breach by any of the STOCKHOLDERS of the provisions of this Section, CSI shall
be entitled to an injunction restraining such STOCKHOLDERS from disclosing, in
whole or in part, such confidential information. Nothing herein shall be
construed as prohibiting CSI from pursuing any other available remedy for such
breach or threatened breach, including the recovery of damages. In the event the
transactions contemplated by this Agreement are not consummated, STOCKHOLDERS
shall have none of the above-mentioned restrictions on their ability to
disseminate confidential information with respect to the COMPANY.

      14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they had
in the past and currently have access to certain confidential information of the
COMPANY, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other

                                    -61-

advisers, provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 14.1, (c) to the Other Founding
Companies and their representatives pursuant to Section 7.1(a), unless (i) such
information becomes known to the public generally through no fault of CSI or
NEWCO, (ii) disclosure is required by law or the order of any governmental
authority under color of law, provided, that prior to disclosing any information
pursuant to this clause (ii), CSI and NEWCO shall, if possible, give prior
written notice thereof to the COMPANY and the STOCKHOLDERS and provide the
COMPANY and the STOCKHOLDERS with the opportunity to contest such disclosure, or
(iii) the disclosing party reasonably believes that such disclosure is required
in connection with the defense of a lawsuit against the disclosing party, and
(d) to the public to the extent necessary or advisable in connection with the
filing of the Registration Statement and the IPO and the securities laws
applicable thereto and to the operation of CSI as a publicly held entity after
the IPO. In the event of a breach or threatened breach by CSI or NEWCO of the
provisions of this Section, the COMPANY and the STOCKHOLDERS shall be entitled
to an injunction restraining CSI and NEWCO from disclosing, in whole or in part,
such confidential information. Nothing herein shall be construed as prohibiting
the COMPANY and the STOCKHOLDERS from pursuing any other available remedy for
such breach or threatened breach, including the recovery of damages.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Funding and Consummation Date.

15.   TRANSFER RESTRICTIONS

                                    -62-

      15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDERS or family members, the trustees
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the STOCKHOLDERS shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of CSI Stock as described in Section 3.1 received by the STOCKHOLDERS in
the Merger. The certificates evidencing the CSI Stock delivered to the
STOCKHOLDERS pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as CSI may deem necessary or appropriate: THE SHARES REPRESENTED BY THIS
CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED,
PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL
NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE,
TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION
PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE WRITTEN REQUEST OF THE
HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND
(AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED
ABOVE.

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The STOCKHOLDERS acknowledge that the shares of
CSI Stock to be delivered to the STOCKHOLDERS pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and therefore may not be resold without compliance with the Act. The
CSI Stock to be acquired by such STOCKHOLDERS pursuant to this Agreement is
being acquired solely for their own respective accounts, for investment

                                    -63-

purposes only, and with no present intention of distributing, selling or
otherwise disposing of it in connection with a distribution. The STOCKHOLDERS
covenant, warrant and represent that none of the shares of CSI Stock issued to
such STOCKHOLDERS will be offered, sold, assigned, pledged, hypothecated,
transferred or otherwise disposed of except after full compliance with all of
the applicable provisions of the Act and the rules and regulations of the SEC.
All the CSI Stock shall bear the following legend in addition to the legend
required under Section 15 of this Agreement: THE SHARES REPRESENTED HEREBY HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE
SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND
APPLICABLE SECURITIES LAW.

      16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDERS are able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and have
such knowledge and experience in financial and business matters that they are
capable of evaluating the merits and risks of the proposed investment in the CSI
Stock. The STOCKHOLDERS party hereto have had an adequate opportunity to ask
questions and receive answers from the officers of CSI concerning any and all
matters relating to the transactions described herein including, without
limitation, the background and experience of the current and proposed officers
and directors of CSI, the plans for the operations of the business of CSI, the
business, operations and financial condition of the Founding Companies other
than the COMPANY, and any plans for additional acquisitions and the like. The
STOCKHOLDERS have asked any and all questions in the nature described in the
preceding sentence and all questions have been answered to their satisfaction.

17.   REGISTRATION RIGHTS

                                    -64-

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
each of the STOCKHOLDERS prompt written notice of its intent to do so. Upon the
written request of any of the STOCKHOLDERS given within 30 days after receipt of
such notice, CSI shall cause to be included in such registration all of the CSI
Stock issued to the STOCKHOLDERS pursuant to this Agreement (including any stock
issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) which any such STOCKHOLDER requests, provided that CSI shall
have the right to reduce the number of shares included in such registration to
the extent that inclusion of such shares could, in the opinion of tax counsel to
CSI or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Registration Statement as a tax-free
organization. In addition, if CSI is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1 that the number
of shares to be sold by persons other than CSI is greater than the number of
such shares which can be offered without adversely affecting the offering, CSI
may reduce pro rata the number of shares offered for the accounts of such
persons (based upon the number of shares held by such person) to a number deemed
satisfactory by such managing underwriter, provided, that, for each such
offering made by CSI after the IPO, such reduction shall be made first by
reducing the number of shares to be sold by persons other than CSI, the
STOCKHOLDERS and the stockholders of the Other Founding Companies (collectively,
the STOCKHOLDERS and the stockholders of the other Founding Companies being
referred to herein as the "Founding Stockholders"), and thereafter, if a further
reduction is required, by reducing the number of shares to be sold by the
Founding Stockholders.

                                    -65-

      17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year after
the Closing and prior to the date three years after the Closing, the holders of
a majority of the shares of CSI Stock issued to the Founding Stockholders
pursuant to this Agreement and the Other Agreements which have not been
previously registered or sold and which are not entitled to be sold under Rule
144(k) (or any similar or successor provision) promulgated under the 1933 Act
may request in writing that CSI file a registration statement under the 1933 Act
covering the registration of the shares of CSI Stock issued to the STOCKHOLDERS
pursuant to this Agreement and the Other Agreements (including any stock issued
as (or issuable upon the conversion or exchange of any convertible security,
warrant, right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) then held by such Founding Stockholders (a "Demand Registration"). Within
ten (10) days of the receipt of such request, CSI shall give written notice of
such request to all other Founding Stockholders and shall, as soon as
practicable but in no event later than 45 days after notice from any
STOCKHOLDER, file and use its best efforts to cause to become effective a
registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

      Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the date on which CSI
would otherwise be required to make such filing pursuant to the foregoing
paragraph.

      If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective date of such registration unless CSI is no longer proceeding
diligently to effect such registration;

                                    -66-

provided that CSI shall provide the Founding Stockholders the right to
participate in such public offering pursuant to, and subject to, Section 17.1
hereof.

      17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with the
registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Sections 17.1 and 17.2 covering an underwritten registered offering, CSI and
each participating holder agree to enter into a written agreement with the
managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
managing underwriters and companies of CSI's size and investment stature,
including indemnification.

      17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by any STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to such STOCKHOLDER.

      17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

                                    -67-

            (i) make and keep public information regarding CSI available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of CSI under the 1933 Act and the 1934 Act at any time
      after it has become subject to such reporting requirements; and

            (iii) so long as a STOCKHOLDER owns any restricted CSI Common Stock,
      furnish to each STOCKHOLDER forthwith upon written request a written
      statement by CSI as to its compliance with the reporting requirements of
      Rule 144 (at any time from and after 90 days following the effective date
      of the Registration Statement, and of the 1933 Act and the 1934 Act (at
      any time after it has become subject to such reporting requirements), a
      copy of the most recent annual or quarterly report of CSI, and such other
      reports and documents so filed as a STOCKHOLDER may reasonably request in
      availing itself of any rule or regulation of the SEC allowing a
      STOCKHOLDER to sell any such shares without registration. 18. GENERAL 18.1
      COOPERATION. The COMPANY, STOCKHOLDERS, CSI and NEWCO shall each

deliver or cause to be delivered to the other on the Funding and Consummation
Date, and at such other times and places as shall be reasonably agreed to, such
additional instruments as the other may reasonably request for the purpose of
carrying out this Agreement. The COMPANY will cooperate and use its reasonable
efforts to have the present officers, directors and employees of the COMPANY
cooperate with CSI on and after the Funding and Consummation Date in furnishing

return filing obligations, actions, proceedings, arrangements or disputes of any
nature with respect to matters pertaining to all periods prior to the Funding

effect and shall remain in full force and effect through the Funding and
Consummation Date. Since January 1, 1994, no insurance carried by the COMPANY

      5.18 COMPENSATION; EMPLOYMENT AGREEMENTS; ORGANIZED LABOR MATTERS. The
COMPANY has delivered to CSI an accurate list (which is set forth on Schedule
5.18) showing all officers, directors and key employees of the COMPANY, listing
all employment agreements with such officers, directors and key employees and

Balance Sheet Date and (ii) the date hereof. The COMPANY has provided to CSI
true, complete and correct copies of any employment agreements for persons

no campaign to establish such representation is in progress and (iv) there is no
pending or, to the best of the COMPANY's knowledge, threatened labor dispute
involving the COMPANY and any group of its employees nor has the COMPANY
experienced any labor interruptions over the past three years. The COMPANY

      5.19 EMPLOYEE PLANS. The STOCKHOLDERS have delivered to CSI an accurate
schedule (Schedule 5.19) showing all employee benefit plans of COMPANY
(including COMPANY's Subsidiaries), including all employment agreements and
other agreements or arrangements containing "golden parachute" or other similar
provisions, and deferred compensation agreements, together with true, complete
and correct copies of such plans, agreements and any trusts related thereto, and
classifications of employees covered thereby as of the Balance Sheet Date.
Except for the employee benefit plans, if any, described on Schedule 5.19,
COMPANY (including the COMPANY's Subsidiaries) does not sponsor, maintain or
contribute to any plan program, fund or arrangement that constitutes an
"employee pension benefit plan," nor has COMPANY or any Subsidiary any
obligation to contribute to or accrue or pay any benefits under any deferred
compensation or retirement funding arrangement on behalf of any employee or
employees (such as, for example, and without limitation, any individual
retirement account or annuity, any "excess benefit plan" (within the meaning of
Section 3(36) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) or any non-qualified deferred compensation arrangement). For the
purposes of this Agreement, the term "employee pension benefit plan" shall have
the same meaning as is given that term in Section 3(2) of ERISA. Neither COMPANY
nor any Subsidiary has sponsored, maintained or contributed to any employee
pension benefit plan other than the plans set forth on Schedule 5.19, nor is
COMPANY or any Subsidiary required to contribute to any retirement plan pursuant
to the provisions of any collective bargaining agreement establishing the terms
and conditions or employment of any of COMPANY's or any Subsidiary's employees.

                                      -21-

      Neither the COMPANY nor any Subsidiary is now, or can as a result of its
past activities become, liable to the Pension Benefit Guaranty Corporation or to
any multiemployer employee pension benefit plan under the provisions of Title IV
of ERISA.

      All employee benefit plans listed on Schedule 5.19 and the administration
thereof are in substantial compliance with their terms and all applicable
provisions of ERISA and the regulations issued thereunder, as well as with all
other applicable federal, state and local statutes, ordinances and regulations.

      All accrued contribution obligations of COMPANY or any Subsidiary with
respect to any plan listed on Schedule 5.19 have either been fulfilled in their
entirety or are fully reflected on the balance sheet of the COMPANY as of the
Balance Sheet Date.

      5.20 COMPLIANCE WITH ERISA. All such plans listed on Schedule 5.19 that
are intended to qualify (the "Qualified Plans") under Section 401(a) of the Code
are, and have been so qualified and have been determined by the Internal Revenue
Service to be so qualified, and copies of such determination letters are
included as part of Schedule 5.19 hereof. Except as disclosed on Schedule 5.20,
all reports and other documents required to be filed with any governmental
agency or distributed to plan participants or beneficiaries (including, but not
limited to, actuarial reports, audits or tax returns) have been timely filed or
distributed, and copies thereof are included as part of Schedule 5.19 hereof.
Neither STOCKHOLDERS, any such plan listed in Schedule 5.19, nor COMPANY
(including the COMPANY's Subsidiaries) has engaged in any transaction prohibited
under the provisions of Section 4975 of the Code or Section 406 of ERISA. No
such Plan listed in Schedule 5.19 has incurred an accumulated funding
deficiency, as defined in Section 412(a) of the Code and Section 302(1) of
ERISA; and COMPANY (including the COMPANY's Subsidiaries) has not incurred any
liability for excise tax or penalty due to the Internal Revenue Service nor any
liability to the Pension Benefit Guaranty Corporation. The STOCKHOLDERS further
represent that:

                                      -22-

            (i) there have been no terminations, partial terminations or
      discontinuance of contributions to any such Qualified Plan intended to
      qualify under Section 401(a) of the Code without notice to and approval by
      the Internal Revenue Service;

            (ii) no such plan listed in Schedule 5.19 subject to the provisions
      of Title IV of ERISA has been terminated;

            (iii) there have been no "reportable events" (as that phrase is
      defined in Section 4043 of ERISA) with respect to any such plan listed in
      Schedule 5.19;

            (iv) COMPANY (including the COMPANY's Subsidiaries) has not incurred
      liability under Section 4062 of ERISA; and

            (v) No circumstances exist pursuant to which the COMPANY could have
      any direct or indirect liability whatsoever (including, but not limited
      to, any liability to any multiemployer plan or the PBGC under Title IV of
      ERISA or to the Internal Revenue Service for any excise tax or penalty, or
      being subject to any statutory lien to secure payment of any such
      liability) with respect to any plan now or heretofore maintained or
      contributed to by any entity other than the COMPANY that is, or at any
      time was, a member of a "controlled group" (as defined in Section
      412(n)(6)(B) of the Code) that includes the COMPANY.

this Agreement, and, subject to the provisions of Section 7.8, at the sole
option of CSI, the truth and accuracy of any and all warranties

                                      -28-

Registration Statement will become effective or that the IPO pursuant thereto
will occur at a particular price or within a particular range of prices or occur
at all; (ii) that neither CSI or any of its officers, directors, agents or
representatives nor any Underwriter shall have any liability to the COMPANY, the

thereto.

      7.7 NOTIFICATION OF CERTAIN MATTERS. The STOCKHOLDERS and the COMPANY
shall give prompt notice to CSI of (i) the occurrence or non-occurrence of any

or satisfy any covenant, condition or agreement to be complied with or satisfied
by such person hereunder. CSI and NEWCO shall give prompt notice to the COMPANY
of (i) the occurrence or non-occurrence of any event the occurrence or
non-occurrence of which would be

                                      -41-

likely to cause any representation or warranty of CSI or NEWCO contained herein

the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the COMPANY that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless CSI and
a majority of the Founding Companies other than the COMPANY consent to such
amendment or supplement; and provided further, that no amendment or supplement
to a Schedule prepared by CSI or NEWCO that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect may be made unless a
majority of the Founding Companies consent to such amendment or supplement. For
all purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other

                                      -42-

Founding Companies seeks to amend or supplement a Schedule pursuant to Section
7.8 of one of the Other Agreements, and such amendment or supplement constitutes
or reflects an event or occurrence that would have a Material Adverse Effect on
such Other Founding Company, CSI shall give the COMPANY notice promptly after it
has knowledge thereof. If CSI and a majority of the Founding Companies consent
to such amendment or supplement, which consent shall have been deemed given by
CSI or any Founding Company if no response is received within 24 hours following
receipt of notice of such amendment or supplement (or sooner if required by the
circumstances under which such consent is requested), but the COMPANY does not
give its consent, the COMPANY may terminate this Agreement pursuant to Section
12.1(iv) hereof. In the event that the COMPANY seeks to amend or supplement a
Schedule pursuant to this Section 7.8, and CSI and a majority of the Other
Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. In the event that CSI or NEWCO seeks to amend or supplement a
Schedule pursuant to this Section 7.8 and a majority of the Founding Companies
do not consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the
anticipated effectiveness of the Registration Statement.

with generally accepted accounting principles, in form suitable for inclusion in
the Registration Statement). The COMPANY and the STOCKHOLDERS agree promptly to

delivered under the Securities Act, any information contained in the prospectus
concerning the COMPANY or the STOCKHOLDERS becomes incorrect or incomplete in
any material respect, and to provide the information needed to correct such
inaccuracy. Insofar as the information relates solely to the COMPANY or the
STOCKHOLDERS, the COMPANY represents and warrants as to such information with
respect to itself, and each Stockholder represents and warrants, as to such
information with respect to the COMPANY and himself or herself, that the
Registration Statement will not include an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

      7.10 FINAL FINANCIAL STATEMENTS. The COMPANY shall provide prior to the
Funding and Consummation Date, and CSI shall have had sufficient time to review

fiscal quarters following the Balance Sheet Date, and the unaudited consolidated
statement of income, cash flows and retained earnings of the COMPANY for all
fiscal quarters ended after the Balance Sheet Date, disclosing no material
adverse change in the financial condition of the COMPANY or the results of its
operations from the financial statements as of the Balance Sheet Date. Such

one or more filings under the Hart-Scott Act may be required in connection with
the transactions contemplated herein. If it is determined by the parties to this
Agreement that filings under the Hart-Scott Act are required, then: (i) each of
the parties hereto agrees to cooperate and use its best efforts to comply with
the Hart-Scott Act, (ii) such compliance by the STOCKHOLDERS and the COMPANY

use its best efforts to have the STOCKHOLDERS released from any and all
guarantees on any indebtedness that they personally guaranteed and from any and
all pledges of assets that they pledged to secure such indebtedness for the
benefit of the COMPANY, with all such guarantees on indebtedness being assumed
by CSI. In the event that CSI cannot obtain such releases from the lenders of
any such guaranteed indebtedness on or prior to 120 days subsequent to the
Funding and Consummation Date, CSI shall pay off or otherwise refinance or
retire such indebtedness. From and after the Funding and Consummation Date and
until such time as all of such indebtedness is paid off, refinanced or retired,

                                      -51-

CSI shall maintain unencumbered funds in amounts sufficient to provide for such
pay off, refinancing or retirement, provided that CSI may use such funds for
other purposes, in its sole discretion, with the prior written consent of each
STOCKHOLDER who has not as of that time been released from his or her guarantee
as described above and whose indebtedness as described above has not as of that
time been paid off, refinanced or retired.

      10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as contemplated
by this Agreement or the Registration Statement, after the Funding and
Consummation Date, CSI shall not and shall not permit any of its subsidiaries to
undertake any act that would jeopardize the tax-free status of the organization,
including without limitation:

            (a) the retirement or reacquisition, directly or indirectly, of all
      or part of the CSI Stock issued in connection with the transactions
      contemplated hereby; or

            (b) the entering into of financial arrangements for the benefit of
      the STOCKHOLDERS.

      10.3  PREPARATION AND FILING OF TAX RETURNS.

            (i) The COMPANY shall, if possible, file or cause to be filed all
      separate Returns of any Acquired Party for all taxable periods that end on
      or before the Funding and Consummation Date. Notwithstanding the
      foregoing, the STOCKHOLDERS shall file or cause to be filed all separate
      federal income Tax Returns (and any State and local Tax Returns filed on
      the basis similar to that of S corporations under federal income Tax
      rules) of any Acquired Party for all taxable periods that end on or before
      the Funding and Consummation Date. Each STOCKHOLDER shall pay or cause to
      be paid all Tax liabilities (in excess of all amounts already paid with
      respect thereto or properly accrued or reserved with respect thereto on
      the COMPANY Financial Statements) shown by such Returns to be due.

            (ii) CSI shall file or cause to be filed all separate Returns of, or
      that include, any Acquired Party for all taxable periods ending after the
      Funding and Consummation Date.

                                      -52-

            (iii) Each party hereto shall, and shall cause its subsidiaries and
      affiliates to, provide to each of the other parties hereto such
      cooperation and information as any of them reasonably may request in
      filing any Return, amended Return or claim for refund, determining a
      liability for Taxes or a right to refund of Taxes or in conducting any
      audit or other proceeding in respect of Taxes. Such cooperation and
      information shall include providing copies of all relevant portions of
      relevant Returns, together with relevant accompanying schedules and
      relevant work papers, relevant documents relating to rulings or other
      determinations by Taxing Authorities and relevant records concerning the
      ownership and Tax basis of property, which such party may possess. Each
      party shall make its employees reasonably available on a mutually
      convenient basis at its cost to provide explanation of any documents or
      information so provided. Subject to the preceding sentence, each party
      required to file Returns pursuant to this Agreement shall bear all costs
      of filing such Returns.

            (iv) Each of the COMPANY, NEWCO, CSI and each STOCKHOLDER shall
      comply with the tax reporting requirements of Section 1.351-3 of the
      Treasury Regulations promulgated under the Code, and treat the transaction
      as a tax-free contribution under Section 351(a) of the Code subject to
      gain, if any, recognized on the receipt of cash or other property under
      Section 351(b) of the Code. 

      10.4 DIRECTORS. The persons named in the draft of the Registration
Statement shall be appointed as directors and elected as officers of CSI, as and
to the extent set forth in the draft of the Registration Statement, promptly
following the Funding and Consummation Date. This provision shall not imply that
the STOCKHOLDERS have any power or duty to elect officers of CSI.

      10.5 PRESERVATION OF EMPLOYEE BENEFIT PLANS. Following the Funding and
Consummation Date, CSI shall not terminate any health insurance, life insurance
or 401(k) plan in effect at the COMPANY until such time as CSI is able to
replace such plan with a plan that is applicable to CSI and all of its then
existing subsidiaries, provided that CSI shall have no obligation

                                      -53-

to provide replacement plans that have the same terms and provisions as the
existing plans, provided, further, that any new health insurance plan shall
provide for coverage for preexisting conditions. On the Funding and Consummation
Date, the employees of the COMPANY will be the employees of the Surviving
Corporation (provided that this provision is for purposes of clarifying that the
Merger, in and of itself, will not have any impact on the employment status of
any employee and provided, further that this provision shall not in any way
limit the management rights of the Surviving Corporation or CSI to assess
workforce needs and make appropriate adjustments as necessary or desirable
within their discretion subject to applicable laws and collective bargaining
agreements).

      10.6 DIVIDENDS. If the COMPANY is an S corporation, the COMPANY may pay to
each STOCKHOLDER as a dividend the full amount of his or her "accumulated
adjustments account" (as defined in Section 1368(e) of the Code) as of the
Balance Sheet Date, and may also pay to the STOCKHOLDERS as a dividend the full
amount of the COMPANY's earnings taxable to such STOCKHOLDERS for the period
after the Balance Sheet Date to the Funding and Consummation Date. If the
COMPANY is a C corporation, the COMPANY may pay to the STOCKHOLDERS as a
dividend the full amount of the COMPANY's earnings for the period after the
Balance Sheet Date to the Funding and Consummation Date. The COMPANY may borrow
funds to the extent necessary to make the payments contemplated by this Section
10.6 and to the extent necessary to ensure that the COMPANY has cash on hand to
adequately fund operations on the Funding and Consummation Date.

11.   INDEMNIFICATION

      The STOCKHOLDERS, CSI and NEWCO each make the following covenants that are
applicable to them, respectively:

      11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDERS. The STOCKHOLDERS
covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless CSI, NEWCO, the COMPANY and the Surviving Corporation
at all times, from and after the date

                                      -54-

of this Agreement until the Expiration Date, from and against all claims,
damages, actions, suits, proceedings, demands, assessments, adjustments, costs
and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by CSI, NEWCO, the
COMPANY or the Surviving Corporation as a result of or arising from (i) any
breach of the representations and warranties of the STOCKHOLDERS or the COMPANY
set forth herein or on the schedules or certificates delivered in connection
herewith, (ii) any breach of any agreement on the part of the STOCKHOLDERS or
the COMPANY under this Agreement, or (iii) any liability under the 1933 Act, the
1934 Act or other Federal or state law or regulation, at common law or
otherwise, arising out of or based upon any untrue statement or alleged untrue
statement of a material fact relating to the COMPANY or the STOCKHOLDERS, and
provided to CSI or its counsel by the COMPANY or the STOCKHOLDERS (but in the
case of the STOCKHOLDERS, only if such statement was provided in writing)
contained in the Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or arising out of or
based upon any omission or alleged omission to state therein a material fact
relating to the COMPANY or the STOCKHOLDERS required to be stated therein or
necessary to make the statements therein not misleading, provided, however, that
such indemnity shall not inure to the benefit of CSI, NEWCO, the COMPANY or the
Surviving Corporation to the extent that such untrue statement (or alleged
untrue statement) was made in, or omission (or alleged omission) occurred in,
any preliminary prospectus and the STOCKHOLDERS provided, in writing, corrected
information to CSI counsel and to CSI for inclusion in the final prospectus, and
such information was not so included or properly delivered, and provided
further, that no STOCKHOLDER shall be liable for any indemnification obligation
pursuant to this Section 11.1 to the extent attributable to a breach of any
representation, warranty or agreement made herein individually by any other
STOCKHOLDER.

      11.2 INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the STOCKHOLDERS at all times from
and after the date of this Agreement until the Expiration Date, from and against
all claims, damages, actions, suits,

                                      -55-

proceedings, demands, assessments, adjustments, costs and expenses (including
specifically, but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by the STOCKHOLDERS as a result of or arising from (i)
any breach by CSI or NEWCO of their representations and warranties set forth
herein or on the schedules or certificates attached hereto, (ii) any
nonfulfillment of any agreement on the part of CSI or NEWCO under this
Agreement, (iii) any liabilities which the STOCKHOLDERS may incur due to CSI's
or NEWCO's failure to be responsible for the liabilities and obligations of the
COMPANY as provided in Section 1 hereof (except to the extent that CSI or NEWCO
has claims against the STOCKHOLDERS by reason of such liabilities); or (iv) any
liability under the 1933 Act, the 1934 Act or other Federal or state law or
regulation, at common law or otherwise, arising out of or based upon any untrue
statement or alleged untrue statement of a material fact relating to CSI, NEWCO
or any of the Other Founding Companies contained in any preliminary prospectus,
the Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to CSI or
NEWCO or any of the Other Founding Companies required to be stated therein or
necessary to make the statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has knowledge of any claim by a
person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 11.1 or 11.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying

                                      -56-

Party shall not settle any criminal proceeding without the written consent of
the Indemnified Party. If the Indemnifying Party undertakes to defend or settle,
it shall promptly notify the Indemnified Party of its intention to do so, and
the Indemnified Party shall cooperate with the Indemnifying Party and its
counsel in the defense thereof and in any settlement thereof. Such cooperation
shall include, but shall not be limited to, furnishing the Indemnifying Party
with any books, records or information reasonably requested by the Indemnifying
Party that are in the Indemnified Party's possession or control. All Indemnified
Parties shall use the same counsel, which shall be the counsel selected by
Indemnifying Party, provided that if counsel to the Indemnifying Party shall
have a conflict of interest that prevents counsel for the Indemnifying Party
from representing Indemnified Party, Indemnified Party shall have the right to
participate in such matter through counsel of its own choosing and Indemnifying
Party will reimburse the Indemnified Party for the reasonable expenses of its
counsel. After the Indemnifying Party has notified the Indemnified Party of its
intention to undertake to defend or settle any such asserted liability, and for
so long as the Indemnifying Party diligently pursues such defense, the
Indemnifying Party shall not be liable for any additional legal expenses
incurred by the Indemnified Party in connection with any defense or settlement
of such asserted liability, except (i) as set forth in the preceding sentence
and (ii) to the extent such participation is requested by the Indemnifying
Party, in which event the Indemnified Party shall be reimbursed by the
Indemnifying Party for reasonable additional legal expenses and out-of-pocket
expenses. If the Indemnifying Party desires to accept a final and complete
settlement of any such Third Person claim and the Indemnified Party refuses to
consent to such settlement, then the Indemnifying Party's liability under this
Section with respect to such Third Person claim shall be limited to the amount
so offered in settlement by said Third Person. Upon agreement as to such
settlement between said Third Person and the Indemnifying Party, the
Indemnifying Party shall, in exchange for a complete release from the
Indemnified Party, promptly pay to the Indemnified Party the amount agreed to in
such settlement and the Indemnified Party shall, from that moment on, bear full
responsibility for any additional costs of defense which it subsequently incurs
with respect to

                                      -57-

such claim and all additional costs of settlement or judgment. If the
Indemnifying Party does not undertake to defend such matter to which the
Indemnified Party is entitled to indemnification hereunder, or fails diligently
to pursue such defense, the Indemnified Party may undertake such defense through
counsel of its choice, at the cost and expense of the Indemnifying Party, and
the Indemnified Party may settle such matter, and the Indemnifying Party shall
reimburse the Indemnified Party for the amount paid in such settlement and any
other liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the Indemnified Party otherwise agrees in writing. The parties
hereto will make appropriate adjustments for insurance proceeds in determining
the amount of any indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. The indemnification provided for in this Section 11
shall (except as prohibited by ERISA) be the exclusive remedy in any action
seeking damages or any other form of monetary relief brought by any party to
this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement.

      11.5 LIMITATIONS ON INDEMNIFICATION. CSI, NEWCO, the Surviving Corporation
and the other persons or entities indemnified pursuant to Section 11.1 or 11.2
shall not assert any claim for indemnification hereunder against the
STOCKHOLDERS until such time as, and solely to the extent that, the aggregate of
all claims which such persons may have against such the STOCKHOLDERS shall
exceed the greater of (a) 1.0% of the sum of the cash paid to STOCKHOLDERS plus
the value of the CSI Stock delivered to STOCKHOLDERS (calculated as provided in
this Section 11.5) or (b) $50,000 (the "Indemnification Threshold").
STOCKHOLDERS shall not assert any claim for indemnification hereunder against
CSI or NEWCO until such time as, and solely to the extent that,

                                      -58-

the aggregate of all claims which STOCKHOLDERS may have against CSI or NEWCO
shall exceed $50,000.

      No person shall be entitled to indemnification under this Section 11 if
and to the extent that such person's claim for indemnification is directly or
indirectly related to a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

      Notwithstanding any other term of this Agreement, no STOCKHOLDER shall be
liable under this Section 11 for an amount which exceeds the amount of proceeds
received by such STOCKHOLDER in connection with the Merger. For purposes of
calculating the value of the CSI Stock received by a STOCKHOLDER, CSI Stock
shall be valued at its initial public offering price as set forth in the
Registration Statement. It is hereby understood and agreed that a STOCKHOLDER
may satisfy an indemnification obligation through payment of a combination of
stock and cash in proportion equal to the proportion of stock and cash received
by such STOCKHOLDER in connection with the Merger, valued as described
immediately above.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION.This Agreement may be terminated at any time prior to the
Funding and Consummation Date solely:

directors), on the one hand, or by CSI (acting through its board of directors),
on the other hand, if the transactions contemplated by this Agreement to take
place at the Closing shall not have been consummated by September 30, 1997,
unless the failure of such transactions to be consummated is due to the willful
failure of the party seeking to terminate this Agreement to perform any of its
obligations under this Agreement to the extent required to be performed by it
prior to or on the Funding and Consummation Date;

      (iii) by the STOCKHOLDERS or COMPANY, on the one hand, or by CSI, on the
other hand, if a material breach or default shall be made by the other party in
the observance or in the due

                                      -59-

and timely performance of any of the covenants or agreements contained herein,
and the curing of such default shall not have been made on or before the Funding
and Consummation Date or by the STOCKHOLDERS, or the COMPANY, if the conditions
set forth in Section 8 hereof have not been satisfied or waived as of the
Closing Date or the Funding and Consummation Date, as applicable, or by CSI, if
the conditions set forth in Section 9 hereof have not been satisfied or waived
as of the Closing Date or the Funding and Consummation Date, as applicable;

      (iv) pursuant to Section 7.8 hereof; or

      (v) pursuant to Section 4 hereof.

      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

(the "Territory");

                                      -60-

      (ii) call upon any person who is, at that time, within the Territory, an
employee of CSI (including the subsidiaries thereof) in a sales representative
or managerial capacity for the purpose or with the intent of enticing such
employee away from or out of the employ of CSI (including the subsidiaries
thereof), provided that each STOCKHOLDER shall be permitted to call upon and
hire any member of his or her immediate family;

      (iii) call upon any person or entity which is, at that time, or which has
been, within one (1) year prior to the Funding and Consummation Date, a customer
of CSI (including the subsidiaries thereof), of the COMPANY or of any of the
Other Founding Companies within the Territory for the purpose of soliciting or
selling products or services in direct competition with CSI within the
Territory;

      (iv) call upon any prospective acquisition candidate, on any STOCKHOLDER's
own behalf or on behalf of any competitor in the heating, ventilation or air
conditioning services business, which candidate, to the actual knowledge of such
STOCKHOLDER after due inquiry, was called upon by CSI (including the
subsidiaries thereof) or for which, to the actual knowledge of such STOCKHOLDER
after due inquiry, CSI (or any subsidiary thereof) made an acquisition analysis,
for the purpose of acquiring such entity; or

      (v) disclose customers, whether in existence or proposed, of the COMPANY
to any person, firm, partnership, corporation or business for any reason or
purpose whatsoever except to the extent that the COMPANY has in the past
disclosed such information to the public for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any STOCKHOLDER from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or over-the-counter.

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
CSI as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that

                                      -61-

could be caused to CSI for which it would have no other adequate remedy, each
STOCKHOLDER agrees that the foregoing covenant may be enforced by CSI in the
event of breach by such STOCKHOLDER, by injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
STOCKHOLDERS in light of the activities and business of CSI (including the
subsidiaries thereof) on the date of the execution of this Agreement and the
current plans of CSI.

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any STOCKHOLDER
against CSI (including the subsidiaries thereof), whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by CSI
of such covenants. It is specifically agreed that the period of five (5) years
stated at the beginning of this Section 13, during which the agreements and
covenants of each STOCKHOLDER made in this Section 13 shall be effective, shall
be computed by excluding from such computation any time during which such
STOCKHOLDER is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

      13.6 MATERIALITY. The COMPANY and the STOCKHOLDERS hereby agree that this
covenant is a material and substantial part of this transaction.

                                      -62-

14.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1 STOCKHOLDERS. The STOCKHOLDERS recognize and acknowledge that they
had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the COMPANY, the Other Founding Companies,
and/or CSI, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's, the Other Founding
Companies' and/or CSI's respective businesses. The STOCKHOLDERS agree that they
will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except (a) to authorized representatives of CSI, (b) following the Closing, such
information may be disclosed by the STOCKHOLDERS as is required in the course of
performing their duties for CSI or the Surviving Corporation and (c) to counsel
and other advisers, provided that such advisers (other than counsel) agree to
the confidentiality provisions of this Section 14.1, unless (i) such information
becomes known to the public generally through no fault of the STOCKHOLDERS, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), the STOCKHOLDERS shall, if possible, give prior written notice
thereof to CSI and provide CSI with the opportunity to contest such disclosure,
or (iii) the disclosing party reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party. In the event of a breach or threatened breach by any of the STOCKHOLDERS
of the provisions of this Section, CSI shall be entitled to an injunction
restraining such STOCKHOLDERS from disclosing, in whole or in part, such
confidential information. Nothing herein shall be construed as prohibiting CSI
from pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. In the event the transactions contemplated by
this Agreement are not consummated, STOCKHOLDERS shall have none of the
above-mentioned restrictions on their ability to disseminate confidential
information with respect to the COMPANY.

                                      -63-

      14.2 CSI AND NEWCO. CSI and NEWCO recognize and acknowledge that they had
in the past and currently have access to certain confidential information of the
COMPANY, such as operational policies, and pricing and cost policies that are
valuable, special and unique assets of the COMPANY's business. CSI and NEWCO
agree that, prior to the Closing, or if the Transactions contemplated by this
Agreement are not consummated, they will not disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except (a) to authorized representatives of
the COMPANY, (b) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, (c) to the Other Founding Companies and their representatives pursuant to
Section 7.1(a), unless (i) such information becomes known to the public
generally through no fault of CSI or NEWCO, (ii) disclosure is required by law
or the order of any governmental authority under color of law, provided, that
prior to disclosing any information pursuant to this clause (ii), CSI and NEWCO
shall, if possible, give prior written notice thereof to the COMPANY and the
STOCKHOLDERS and provide the COMPANY and the STOCKHOLDERS with the opportunity
to contest such disclosure, or (iii) the disclosing party reasonably believes
that such disclosure is required in connection with the defense of a lawsuit
against the disclosing party, and (d) to the public to the extent necessary or
advisable in connection with the filing of the Registration Statement and the
IPO and the securities laws applicable thereto and to the operation of CSI as a
publicly held entity after the IPO. In the event of a breach or threatened
breach by CSI or NEWCO of the provisions of this Section, the COMPANY and the
STOCKHOLDERS shall be entitled to an injunction restraining CSI and NEWCO from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting the COMPANY and the STOCKHOLDERS from pursuing
any other available remedy for such breach or threatened breach, including the
recovery of damages.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and

                                      -64-

irreparable damage that would be caused for which they would have no other
adequate remedy, the parties hereto agree that, in the event of a breach by any
of them of the foregoing covenants, the covenant may be enforced against the
other parties by injunctions and restraining orders.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Funding and Consummation Date.

15.   TRANSFER RESTRICTIONS

      15.1 TRANSFER RESTRICTIONS. Except for transfers to immediate family
members who agree to be bound by the restrictions set forth in this Section 15.1
(or trusts for the benefit of the STOCKHOLDERS or family members, the trustees
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the STOCKHOLDERS shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of CSI Stock as described in Section 3.1 received by the STOCKHOLDERS in
the Merger. The certificates evidencing the CSI Stock delivered to the
STOCKHOLDERS pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as CSI may deem necessary or appropriate: THE SHARES REPRESENTED BY THIS
CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED,
PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL
NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE,
TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION
PRIOR TO THE FIRST ANNIVERSARY OF CLOSING DATE. UPON THE WRITTEN REQUEST OF THE
HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND
(AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED
ABOVE.

                                      -65-

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The STOCKHOLDERS acknowledge that the shares of
CSI Stock to be delivered to the STOCKHOLDERS pursuant to this Agreement have
not been and will not be registered under the Act (except as provided in Section
17 hereof) and may not be resold without compliance with the Act. The CSI Stock
to be acquired by such STOCKHOLDERS pursuant to this Agreement is being acquired
solely for their own respective accounts, for investment purposes only, and with
no present intention of distributing, selling or otherwise disposing of it in
connection with a distribution. The STOCKHOLDERS covenant, warrant and represent
that none of the shares of CSI Stock issued to such STOCKHOLDERS will be
offered, sold, assigned, pledged, hypothecated, transferred or otherwise
disposed of except after full compliance with all of the applicable provisions
of the Act and the rules and regulations of the SEC. All the CSI Stock shall
bear the following legend in addition to the legend required under Section 15 of
this Agreement: THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED
IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

      16.2 ECONOMIC RISK; SOPHISTICATION. The STOCKHOLDERS are able to bear the
economic risk of an investment in the CSI Stock to be acquired pursuant to this
Agreement and can afford to sustain a total loss of such investment and have
such knowledge and experience in financial and business matters that they are
capable of evaluating the merits and risks of the proposed investment in the CSI
Stock. The STOCKHOLDERS party hereto have had an adequate opportunity to ask
questions and receive answers from the officers of CSI concerning any and all
matters relating to the transactions described herein including, without
limitation, the background and experience of the current and proposed officers
and directors of CSI, the plans for the operations of the business of CSI, the
business, operations and financial condition of the Founding Companies other
than the

                                      -66-

COMPANY, and any plans for additional acquisitions and the like. The
STOCKHOLDERS have asked any and all questions in the nature described in the
preceding sentence and all questions have been answered to their satisfaction.

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever CSI proposes to register any CSI Stock for its own or others account
under the 1933 Act for a public offering, other than (i) any shelf registration
of shares to be used as consideration for acquisitions of additional businesses
by CSI and (ii) registrations relating to employee benefit plans, CSI shall give
each of the STOCKHOLDERS prompt written notice of its intent to do so. Upon the
written request of any of the STOCKHOLDERS given within 30 days after receipt of
such notice, CSI shall cause to be included in such registration all of the CSI
Stock issued to the STOCKHOLDERS pursuant to this Agreement (including any stock
issued as (or issuable upon the conversion or exchange of any convertible
security, warrant, right or other security which is issued by CSI as) a dividend
or other distribution with respect to, or in exchange for, or in replacement of
such CSI Stock) which any such STOCKHOLDER requests, provided that CSI shall
have the right to reduce the number of shares included in such registration to
the extent that inclusion of such shares could, in the opinion of tax counsel to
CSI or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Registration Statement as a tax-free
organization. In addition, if CSI is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1 that the number
of shares to be sold by persons other than CSI is greater than the number of
such shares which can be offered without adversely affecting the offering, CSI
may reduce pro rata the number of shares offered for the accounts of such
persons (based upon the number of shares held by such person) to a number deemed
satisfactory by such managing underwriter, provided, that, for each such
offering made by CSI after the IPO, such reduction shall be made first by
reducing the number

                                      -67-

of shares to be sold by persons other than CSI, the STOCKHOLDERS and the
stockholders of the Other Founding Companies (collectively, the STOCKHOLDERS and
the stockholders of the other Founding Companies being referred to herein as the
"Founding Stockholders"), and thereafter, if a further reduction is required, by
reducing the number of shares to be sold by the Founding Stockholders.

      17.2 DEMAND REGISTRATION RIGHTS. At any time after the date one year after
the Closing and prior to the date three years after the Closing, the holders of
a majority of the shares of CSI Stock issued to the Founding Stockholders
pursuant to this Agreement and the Other Agreements which have not been
previously registered or sold and which are not entitled to be sold under Rule
144(k) (or any similar or successor provision) promulgated under the 1933 Act
may request in writing that CSI file a registration statement under the 1933 Act
covering the registration of the shares of CSI Stock issued to the STOCKHOLDERS
pursuant to this Agreement and the Other Agreements (including any stock issued
as (or issuable upon the conversion or exchange of any convertible security,
warrant, right or other security which is issued by CSI as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such CSI
Stock) then held by such Founding Stockholders (a "Demand Registration"). Within
ten (10) days of the receipt of such request, CSI shall give written notice of
such request to all other Founding Stockholders and shall, as soon as
practicable but in no event later than 45 days after notice from any
STOCKHOLDER, file and use its best efforts to cause to become effective a
registration statement covering all such shares. CSI shall be obligated to
effect only one Demand Registration for all Founding Stockholders and will keep
such Demand Registration current and effective for not less than 90 days (or
such shorter period as is required to sell all of the shares registered
thereby).

      Notwithstanding the foregoing paragraph, following any such a demand, a
majority of CSI's disinterested directors (i.e. directors who have not demanded
or elected to sell shares in any such public offering) may defer the filing of
the registration statement for up to a 30 day period after the

                                      -68-

date on which CSI would otherwise be required to make such filing pursuant to
the foregoing paragraph.

      If at the time of any request by the Founding Stockholders for a Demand
Registration CSI has fixed plans to file within 60 days after such request a
registration statement covering the sale of any of its securities in a public
offering under the 1933 Act, no registration of the Founding Stockholders' CSI
Stock shall be initiated under this Section 17.2 until 90 days after the
effective date of such registration unless CSI is no longer proceeding
diligently to effect such registration; provided that CSI shall provide the
Founding Stockholders the right to participate in such public offering pursuant
to, and subject to, Section 17.1 hereof.

      17.3 REGISTRATION PROCEDURES. All expenses incurred in connection with the
registrations under this Article 17 (including all registration, filing,
qualification, legal, printer and accounting fees, but excluding underwriting
commissions and discounts), shall be borne by CSI. In connection with
registrations under Sections 17.1 and 17.2, CSI shall (i) use its best efforts
to prepare and file with the SEC as soon as reasonably practicable, a
registration statement with respect to the CSI Stock and use its best efforts to
cause such registration to promptly become and remain effective for a period of
at least 90 days (or such shorter period during which holders shall have sold
all CSI Stock which they requested to be registered); (ii) use its best efforts
to register and qualify the CSI Stock covered by such registration statement
under applicable state securities laws as the holders shall reasonably request
for the distribution for the CSI Stock; and (iii) take such other actions as are
reasonable and necessary to comply with the requirements of the 1933 Act and the
regulations thereunder.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Sections 17.1 and 17.2 covering an underwritten registered offering, CSI and
each participating holder agree to enter into a written agreement with the
managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such

                                      -69-

managing underwriters and companies of CSI's size and investment stature,
including indemnification.

      17.5 AVAILABILITY OF RULE 144. CSI shall not be obligated to register
shares of CSI Stock held by any STOCKHOLDER at any time when the resale
provisions of Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act are available to such STOCKHOLDER.

      17.6 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of CSI stock
to the public without registration, CSI agrees to use its best efforts to:

            (i) make and keep public information regarding CSI available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of CSI under the 1933 Act and the 1934 Act at any time
      after it has become subject to such reporting requirements; and

            (iii) so long as a STOCKHOLDER owns any restricted CSI Common Stock,
      furnish to each STOCKHOLDER forthwith upon written request a written
      statement by CSI as to its compliance with the reporting requirements of
      Rule 144 (at any time from and after 90 days following the effective date
      of the Registration Statement, and of the 1933 Act and the 1934 Act (at
      any time after it has become subject to such reporting requirements), a
      copy of the most recent annual or quarterly report of CSI, and such other
      reports and documents so filed as a STOCKHOLDER may reasonably request in
      availing itself of any rule or regulation of the SEC allowing a
      STOCKHOLDER to sell any such shares without registration.

      18.   GENERAL

      18.1 COOPERATION. The COMPANY, STOCKHOLDERS, CSI and NEWCO shall each
deliver or cause to be delivered to the other on the Funding and Consummation
Date, and at such

                                      -70-

other times and places as shall be reasonably agreed to, such additional
instruments as the other may reasonably request for the purpose of carrying out
this Agreement. The COMPANY will cooperate and use its reasonable efforts to
have the present officers, directors and employees of the COMPANY cooperate with
CSI on and after the Funding and Consummation Date in furnishing information,

      18.3 ENTIRE AGREEMENT. This Agreement (including the schedules, exhibits
and annexes attached hereto) and the documents delivered pursuant hereto
constitute the entire agreement and understanding among the STOCKHOLDERS, the
COMPANY, NEWCO and CSI and supersede any prior agreement and understanding
relating to the subject matter of this Agreement. This Agreement, upon

a written instrument executed by the STOCKHOLDERS, the COMPANY, NEWCO and CSI,
acting through their respective officers or trustees, duly authorized by their
respective Boards of Directors. Any disclosure made on any Schedule delivered

Schedules.

      18.4 COUNTERPARTS. This Agreement may be executed simultaneously in two
(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

                                      -71-

      18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each party
represents and warrants that it employed no broker or agent in connection with
this transaction and agrees to indemnify the other parties hereto against all
loss, cost, damages or expense arising out of claims for fees or commission of
brokers employed or alleged to have been employed by such indemnifying party.

      18.6 EXPENSES. Whether or not the transactions herein contemplated shall

similar taxes and fees ("Transfer Taxes") imposed in connection with the Merger,
other than Transfer Taxes, if any, imposed by the State of Delaware. Each
STOCKHOLDER shall file all necessary documentation and Returns with respect to
such Transfer Taxes. In addition, each STOCKHOLDER acknowledges that he, and not

payable pursuant to Section 2 hereof, and will assume all tax risks and
liabilities of such STOCKHOLDER in connection with the transactions contemplated
hereby.

provisions of this Agreement shall not in any way be affected or impaired
thereby.

        The name of the corporation is:

                            Comfort Systems USA, Inc.

qualifications, limitations or restrictions thereof, in respect of each class of
stock of the Corporation is as follows:

                                 PREFERRED STOCK

        The Preferred Stock may be issued from time to time by the Board of
Directors as shares of one or more classes or series. Subject to the provisions
of this Certificate of Incorporation and the limitations prescribed by law, the
Board of Directors is expressly authorized by adopting resolutions to issue the
shares, fix the number of shares and change the number of shares constituting
any series, and to provide for or change the voting powers, designations,
preferences and relative, participating, optional or other special rights,
qualifications, limitations or restrictions thereof, including dividend

                                       -2-

rights (and whether dividends are cumulative), dividend rates, terms of
redemption (including sinking fund provisions), a redemption price or prices,
conversion rights and liquidation preferences of the shares constituting any
class or series of the Preferred Stock, without any further action or vote by
the stockholders.

                                  COMMON STOCK

        1.     DIVIDENDS.

        Subject to the preferred rights of the holders of shares of any class or
series of Preferred Stock as provided by the Board of Directors with respect to
any such class or series of Preferred Stock, the holders of the Common Stock
shall be entitled to receive, as and when declared by the Board of Directors out
of the funds of the Corporation legally available therefor, such dividends
(payable in cash, stock or otherwise) as the Board of Directors may from time to
time determine, payable to stockholders of record on such dates, not exceeding
60 days preceding the dividend payment dates, as shall be fixed for such purpose
by the Board of Directors in advance of payment of each particular dividend. All
dividends on Common Stock shall be paid PARI PASSU with dividends on Restricted
Voting Common Stock.

        2.     LIQUIDATION.

        In the event of any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, after the distribution or payment
to the holders of shares of any class or series of Preferred Stock as provided
by the Board of Directors with respect to any such class or series of Preferred
Stock, the remaining assets of the Corporation available for distribution to
stockholders shall be distributed among and paid to the holders of Common Stock
and Restricted Voting Common Stock ratably in proportion to the number of shares
of Common Stock and Restricted Voting Common Stock held by them respectively.

        3.     VOTING RIGHTS.

        Except as otherwise required by law, each holder of shares of Common
Stock shall be entitled to one vote for each share of Common Stock standing in
such holder's name of the books of the Corporation.

                         RESTRICTED VOTING COMMON STOCK

        1.     DIVIDENDS.

                                       -3-

        Subject to the preferred rights of the holders of shares of any class or
series of Preferred Stock as provided by the Board of Directors with respect to
any such class or series of Preferred Stock, the holders of the Restricted
Voting Common Stock shall be entitled to receive, as and when declared by the
Board of Directors out of the funds of the Corporation legally available
therefor, such dividends (payable in cash, stock or otherwise) as the Board of
Directors may from time to time determine, payable to stockholders of record on
such dates, not exceeding 60 days preceding the dividend payment dates, as shall
be fixed for such purpose by the Board of Directors in advance of payment of
each particular dividend. All dividends on Restricted Voting Common Stock shall
be paid PARI PASSU with dividends on Common Stock.

        2.     LIQUIDATION.

        In the event of any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, after the distribution or payment
to the holders of shares of any class or series of Preferred Stock as provided
by the Board of Directors with respect to any such class or series of Preferred
Stock, the remaining assets of the Corporation available for distribution to
stockholders shall be distributed among and paid to the holders of Restricted
Voting Common Stock and Common Stock ratably in proportion to the number of
shares of Restricted Voting Common Stock and Common Stock held by them
respectively.

        3.     VOTING RIGHTS.

        Except as otherwise required by law, each holder of shares of Restricted
Voting Common Stock shall be entitled to one-half vote for each share of
Restricted Voting Common Stock standing in such holder's name of the books of
the Corporation.

        4.     CONVERSION OF THE RESTRICTED VOTING COMMON STOCK.

        Each share of Restricted Voting Common Stock will automatically convert
into Common Stock on a share for share basis (a) in the event of a disposition
of such share of Restricted Voting Common Stock by the holder thereof, (b) in
the event any person acquires beneficial ownership of 15% or more of the
outstanding shares of Common Stock of the Corporation, (c) in the event any
person offers to acquire 15% or more of the outstanding shares of Common Stock
of the Corporation, (d) in the event the holder of Restricted Voting Common
Stock elects to convert it into Common Stock at any time after the second
anniversary of the consummation of the Corporation's initial public offering of
its Common Stock (the "Public Offering"), (e) on the fifth anniversary of the
date of the consummation of the Corporation's Public Offering, or (f) in the
event a majority of the aggregate number of votes which may be cast by the
holders of outstanding shares of Common Stock and Restricted Voting Common Stock
entitled to vote approve such conversion. In addition,

                                       -4-

at such time as the over-allotment option granted in favor of the Underwriters
of the Corporation's Public Offering has been exercised in full or expires, a
number of shares of Restricted Voting Common Stock determined in accordance with
the following sentence will automatically convert into Common Stock. The number
of shares of Restricted Voting Common Stock to be converted automatically
following the exercise in full or expiration of such Underwriters'
over-allotment option will be equal to that number of shares of Restricted
Voting Common Stock so that the aggregate number of votes attributable to (i)
the shares of Common Stock issued and outstanding prior to the Public Offering
(excluding for purposes of the preceding clause any shares of Common Stock
issued contemporaneously with the consummation of the Public Offering in
connection with mergers with or acquisitions of corporations), (ii) shares of
Common Stock issued on conversion of shares of Restricted Voting Common Stock,
and (iii) unconverted shares of Restricted Voting Common Stock, equals 19.9
percent of the aggregate number of votes attributable to all shares of Common
Stock and Restricted Voting Common Stock issued and outstanding immediately
following the exercise in full or expiration of the Underwriters' over-allotment
option.

        After July 1, 1998, the Corporation may elect to convert any outstanding
shares of Restricted Voting Common Stock into shares of Common Stock in the
event 80% or more of the outstanding shares of Restricted Voting Common Stock
have been converted into shares of Common Stock.

                                  ARTICLE FIVE

        1.     BOARD OF DIRECTORS.

        The Directors shall be classified with respect to the time for which
they shall severally hold office into three classes as nearly equal in number as
possible. The Class I directors shall be elected to hold office for an initial
term expiring at the 1998 annual meeting of stockholders, the Class II Directors
shall be elected to hold office for an initial term expiring at the 1999 annual
meeting of stockholders and the Class III Directors shall be elected to hold
office for an initial term expiring at the 2000 annual meeting of stockholders,
with the members of each class of directors to hold office until their
successors have been duly elected and qualified. At each annual meeting of
stockholders, the successors to the class of directors whose term expires at
that meeting shall be elected to hold office for a term expiring at the annual
meeting of stockholders held in the third year following the year of their
election and until their successors have been duly elected and qualified. At
each annual meeting of stockholders at which a quorum is present, the persons
receiving a plurality of the votes cast shall be directors. No director or class
of directors may be removed from office by a vote of the stockholders at any
time except for cause. Election of directors need not be by written ballot
unless the Bylaws of the Corporation so provide.

                                       -5-

        Notwithstanding the foregoing, the holders of Restricted Voting Common
Stock shall be entitled to elect one member of the Board of Directors, and only
the holders of the Restricted Voting Common Stock shall be entitled to remove
such member from the Board of Directors.

        2.     VACANCIES.

        Any vacancy on the Board of Directors resulting from death, retirement,
resignation, disqualification or removal from office or other cause, as well as
any vacancy resulting from an increase in the number of directors which occurs
between annual meetings of the stockholders at which directors are elected,
shall be filled only by a majority vote of the remaining directors then in
office, though less than a quorum, except that those vacancies resulting from
removal from office by a vote of the stockholders may be filled by a vote of the
stockholders at the same meeting at which such removal occurs. The directors
chosen to fill vacancies shall hold office for a term expiring at the end of the
next annual meeting of stockholders at which the term of the class to which they
have been elected expires. No decrease in the number of directors constituting
the Board of Directors shall shorten the term of any incumbent director. If the
vacancy on the Board of Directors results from the death, retirement,
resignation, disqualification or removal from office of the director elected by
the holders of the Restricted Voting Common Stock, only the holders of the
Restricted Voting Common Stock shall be entitled to fill such vacancy.

        Notwithstanding the foregoing, whenever the holders of one or more
classes or series of Preferred Stock shall have the right, voting separately, as
a class or series, to elect directors, the election, term of office, filling of
vacancies, removal and other features of such directorships shall be governed by
the terms of the resolution or resolutions adopted by the Board of Directors
pursuant to ARTICLE FOUR applicable thereto, and each director so elected shall
not be subject to the provisions of this ARTICLE FIVE unless otherwise provided
therein.

        3.     POWER TO MAKE, ALTER AND REPEAL BYLAWS.

        In furtherance and not in limitation of the powers conferred by statute,
the Board of Directors is expressly authorized to make, alter and repeal the
Bylaws of the Corporation.

        4.     AMENDMENT AND REPEAL OF ARTICLE FIVE.

        Notwithstanding any provision of this Certificate of Incorporation and
of the Bylaws, and notwithstanding the fact that a lesser percentage may be
specified by Delaware law, unless such action has been approved by a majority
vote of the full Board of Directors, the affirmative vote of 66 2/3 percent of
the votes which all stockholders of the then outstanding shares of capital stock
of the Corporation would be entitled to cast thereon, voting together as a
single class, shall be required

                                       -6-

to amend or repeal any provisions of this ARTICLE FIVE or to adopt any provision
inconsistent with this ARTICLE FIVE. In the event such action has been
previously approved by a majority vote of the full Board of Directors, the
affirmative vote of a majority of the outstanding stock entitled to vote thereon
shall be sufficient to amend or repeal any provision of this ARTICLE FIVE or
adopt any provision inconsistent with this ARTICLE FIVE.

                                   ARTICLE SIX

        The Corporation reserves the right to amend, alter, change or repeal any
provision in this Certificate of Incorporation, in the manner now or hereafter
prescribed by statute.

                                  ARTICLE SEVEN

        No director of the Corporation shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law or (iv) for any transaction
from which the director derived an improper personal benefit.

                                  ARTICLE EIGHT

        The Corporation shall, to the fullest extent permitted by Section 145 of
the Delaware General Corporation Law, as the same may be amended and
supplemented, indemnify each director and officer of the Corporation from and
against any and all of the expenses, liabilities or other matters referred to in
or covered by said section and the indemnification provided for herein shall not
be deemed exclusive of any other rights to which those indemnified may be
entitled under any Bylaw, agreement, vote of stockholders, vote of disinterested
directors or otherwise, and shall continue as to a person who has ceased to be a
director or officer and shall inure to the benefit of the heirs, executors and
administrators of such persons and the Corporation may purchase and maintain

                      timely, a Stockholder's notice

                      shall be delivered to the Secretary at the principal
                      executive offices of the Corporation not later than the
                      close of business on the sixtieth (60th) day nor earlier
                      than the close of business on the ninetieth (90th) day
                      prior to the first (1st) anniversary of the preceding
                      year's annual meeting; PROVIDED, HOWEVER, that in the
                      event that the date of the annual meeting is more than
                      thirty (30) days before or more than sixty (60) days after

                      timely must be so delivered not earlier than the close of
                      business on the ninetieth (90th) day prior to such annual

                      public announcement of the date of such meeting is first
                      made by the Corporation. In no event shall the public
                      announcement of an adjournment of an annual meeting
                      commence a new time period for the giving of a
                      Stockholders's notice as described above. Such
                      Stockholder's notice shall set forth:

                             (A) as to each person whom the Stockholder proposes
                             to nominate for election or reelection as a
                             Director all information relating to such person
                             that is required to be disclosed in solicitations
                             of proxies for election of Directors in an election
                             contest, or is otherwise required, in each case
                             pursuant to Regulation 14A under the Securities
                             Exchange Act of 1934, as amended (the "EXCHANGE
                             ACT") and Rule 14a-11 thereunder (including such
                             person's written consent to being named in the
                             proxy statement as a nominee and to serving as a
                             Director if elected);

                             (B) as to any other business that the Stockholder
                             proposes to bring before the meeting, a brief
                             description of the business desired to be brought
                             before the meeting, the reasons for conducting such
                             business at the meeting and any material interest
                             in such business of such Stockholder and the
                             beneficial owner, if any, on whose behalf the
                             proposal is made; and

                             (C) as to the Stockholder giving the notice and the
                             beneficial owner, if any, on whose behalf the
                             nomination or proposal is made (1) the name and
                             address of such Stockholder, as they appear on the
                             Corporations's books, and of such beneficial owner
                             and (2) the class and number of shares of the
                             Corporation which are owned beneficially and of

                             owner.

                                       -2-

                      (iii) Notwithstanding anything in the second sentence of
                      Section 3(a)(ii) of this ARTICLE I to the contrary, in the
                      event that the number of Directors to be elected to the
                      Board of Directors is increased and there is no public
                      announcement by the Corporation naming all of the nominees
                      for Director or specifying the size of the increased Board
                      of Directors at least seventy (70) days prior to the first
                      (1st) anniversary of the preceding year's annual meeting,
                      a Stockholder's notice required by this Section shall also
                      be considered timely, but only with respect to nominees
                      for any new positions created by such increase, if it
                      shall be delivered to the Secretary at the principal
                      executive offices of the Corporation not later than the
                      close of business on the tenth (10th) day following the
                      day on which such public announcement is first made by the
                      Corporation.

               (b) SPECIAL MEETINGS OF STOCKHOLDERS. Only such business shall be
               conducted at a special meeting of Stockholders as shall have been
               brought before the meeting pursuant to the Corporation's notice
               of meeting. Nominations of persons for election to the Board of
               Directors may be made at a special meeting of Stockholders at
               which Directors are to be elected pursuant to the Corporation's
               notice of meeting (a) by or at the direction of the Board of
               Directors or (b) provided that the Board of Directors has
               determined that Directors shall be elected at such meeting, by
               any Stockholder who is a Stockholder of record at the time of
               giving of notice provided for in this Section 3, who shall be
               entitled to vote at the meeting and who complies with the notice
               procedures set forth in this Section 3. In the event the
               Corporation calls a special meeting of Stockholders for the
               purpose of electing one or more Directors to the Board of
               Directors, any such Stockholder may nominate a person or persons
               (as the case may be), for election to such positions(s) as
               specified in the Corporation's notice of meeting, if the
               Stockholder's notice required by Section 3(a)(ii) of this ARTICLE
               I shall be delivered to the Secretary at the principal executive
               offices of the Corporation not earlier than the close of business
               on the ninetieth (90th) day prior to such special meeting and not
               later than the close of business on the later of the sixtieth
               (60th) day prior to such special meeting or the tenth (10th) day
               following the day on which public announcement is first made of
               the date of the special meeting and of the nominees proposed by
               the Board of Directors to be elected at such meeting. In no event
               shall the public announcement of an adjournment of a special
               meeting commence a new time period for the giving of a
               Stockholder's notice as described above.

                                       -3-

               (c)    GENERAL.

                      (i) Only such persons who are nominated in accordance with
                      the procedures set forth in this Section 3 shall be
                      eligible to serve as Directors and only such business
                      shall be conducted at a meeting of Stockholders as shall
                      have been brought before the meeting in accordance with
                      the procedures set forth in this Section 3. Except as
                      otherwise provided by applicable law, the Chairman of the
                      meeting shall have the power and duty to determine whether
                      a nomination or any business proposed to be brought before
                      the meeting was made or proposed, as the case may be, in
                      accordance with the procedures set forth in this Section 3
                      and, if any proposed nomination or business is not in
                      compliance with this Section 3, to declare that such
                      defective proposal or nomination shall be disregarded.

                      (ii) For purposes of this Section 3, "public announcement"
                      shall mean disclosure in a press release reported by the
                      Dow Jones News Service, Associate Press or comparable
                      national news service or in a document publicly filed by
                      the Corporation with the Securities and Exchange
                      Commission pursuant to Section 13, 14 or 15(d) of the
                      Exchange Act.

                      (iii) Notwithstanding the foregoing provisions of this
                      Section 3, a Stockholder shall also comply with all
                      applicable requirements of the Exchange Act and the rules
                      and regulations thereunder with respect to the matters set
                      forth in this Section 3. Nothing in this Section 3 shall
                      be deemed to affect any rights (A) of Stockholders to
                      request inclusion of proposals in the Corporation's proxy
                      statement pursuant to Rule 14a-8 under the Exchange Act;
                      or (B) of the holders of any series of Common Stock or
                      Preferred Stock or any outstanding voting indebtedness to
                      elect Directors under specified circumstances.

        Notwithstanding any other provisions of the Certificate of Incorporation
of the Corporation, and notwithstanding that a lesser percentage may be
permitted from time to time by applicable law, no provision of this Section 3 of
ARTICLE I may be altered, amended or repealed in any respect, nor may any
provision inconsistent therewith be adopted, unless such alteration, amendment,
repeal or adoption is approved by the affirmative vote of the holders of at
least 80 percent of the combined voting power of the then outstanding shares of
the Corporation's stock entitled to vote generally at elections of Directors
voting together as a single class, and at least 80 percent of each class, series
and issuance of combined voting power of the then outstanding shares of the
Corporation's stock entitled to vote generally at elections of Directors voting
separately as a class, series and issuance.

                                       -4-

        SECTION 4. QUORUM. At any meeting of the stockholders, the holders of a
majority in number of the total outstanding shares of stock of the Corporation
entitled to vote at such meeting, present in person or represented by proxy,
shall constitute a quorum of the stockholders for all purposes, unless the
representation of a larger number of shares shall be required by law, by the
Certificate of Incorporation or by these Bylaws, in which case the
representation of the number of shares so required shall constitute a quorum;
provided that at any meeting of the stockholders at which the holders of any
class of stock of the Corporation shall be entitled to vote separately as a
class, the holders of a majority in number of the total outstanding shares of
such class, present in person or represented by proxy, shall constitute a quorum
for purposes of such class vote unless the representation of a larger number of
shares of such class shall be required by law, by the Certificate of
Incorporation or by these Bylaws.

        SECTION 5. ADJOURNED MEETINGS. Whether or not a quorum shall be present
in person or represented at any meeting of the stockholders, the holders of a
majority in number of the shares of stock of the Corporation present in person
or represented by proxy and entitled to vote at such meeting may adjourn from
time to time; provided, however, that if the holders of any class of stock of
the Corporation are entitled to vote separately as a class upon any matter at
such meeting, any adjournment of the meeting in respect of action by such class
upon such matter shall be determined by the holders of a majority of the shares
of such class present in person or represented by proxy and entitled to vote at
such meeting. When a meeting is adjourned to another time or place, notice need
not be given of the adjourned meeting if the time and place thereof are
announced at the meeting at which the adjournment is taken. At the adjourned
meeting the stockholders, or the holders of any class of stock entitled to vote
separately as a class, as the case may be, may transact any business which might
have been transacted by them at the original meeting. If the adjournment is for
more than thirty days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each stockholder of record entitled to vote at the adjourned meeting.

        SECTION 6. ORGANIZATION. Each annual and special meeting of Stockholders
held in person shall be presided over by a chairman, who shall have the
exclusive authority to, among other things, determine (a) whether business and
nominations have been properly brought before such meetings, and (b) the order
in which business and nominations properly brought before such meeting shall be
considered. The chairman of each annual and special meeting shall be the
Chairman of the Board of Directors, or such person as shall be appointed by the
resolution approved by the majority of the Board of Directors.

        The Secretary of the Corporation shall act as Secretary of all meetings
of the stockholders; but in the absence of the Secretary, the Chairman may
appoint any person to act as Secretary of the meeting. It shall be the duty of
the Secretary to prepare and make, at least ten (10) days before every meeting
of stockholders, a complete list of stockholders entitled to vote at such
meeting, arranged
                                       -5-

in alphabetical order and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open,
either at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting or, if not so specified, at the
place where the meeting is to be held, for the ten (10) days next preceding the
meeting, to the examination of any stockholder, for any purpose germane to the
meeting, during ordinary business hours, and shall be produced and kept at the
time and place of the meeting during the whole time thereof and subject to the
inspection of any stockholder who may be present.

        SECTION 7. VOTING. Except as otherwise provided in the Certificate of
Incorporation or by law, each stockholder shall be entitled to one vote for each
share of the capital stock of the Corporation registered in the name of such
stockholder upon the books of the Corporation. Each stockholder entitled to vote
at a meeting of stockholders or to express consent or dissent to corporate
action in writing without a meeting may authorize another person or persons to
act for him by proxy, but no such proxy shall be voted or acted upon after three
years from its date, unless the proxy provides for a longer period. When
directed by the presiding officer or upon the demand of any stockholder, the
vote upon any matter before a meeting of stockholders shall be by ballot. Except
as otherwise provided by law or by the Certificate of Incorporation, Directors
shall be elected by a plurality of the votes cast at a meeting of stockholders
by the stockholders entitled to vote in the election and, whenever any corporate
action, other than the election of Directors is to be taken, it shall be
authorized by a majority of the votes cast at a meeting of stockholders by the
stockholders entitled to vote thereon.

        Shares of the capital stock of the Corporation belonging to the
Corporation or to another corporation, if a majority of the shares entitled to
vote in the election of directors of such other corporation is held, directly or
indirectly, by the Corporation, shall neither be entitled to vote nor be counted
for quorum purposes.

        SECTION 8. INSPECTORS. When required by law or directed by the presiding
officer or upon the demand of any stockholder entitled to vote, but not
otherwise, the polls shall be opened and closed, the proxies and ballots shall
be received and taken in charge, and all questions touching the qualification of
voters, the validity of proxies and the acceptance or rejection of votes shall
be decided at any meeting of the stockholders by two or more Inspectors who may
be appointed by the Board of Directors before the meeting, or if not so
appointed, shall be appointed by the presiding officer at the meeting. If any
person so appointed fails to appear or act, the vacancy may be filled by
appointment in like manner.

        SECTION 9. ACTION WITHOUT MEETING. Unless otherwise provided in the
Certificate of Incorporation of the Corporation, prior to a firm commitment
underwritten public offering of the Corporation's Common Stock in which gross
proceeds equal or exceed $25 million before deducting underwriters' discounts
and other expenses of the offering (the "Offering"), any action permitted or

                                       -6-

required by law, the Certificate of Incorporation of the Corporation or these
Bylaws to be taken at a meeting of stockholders, may be taken without a meeting,
without prior notice and without a vote, if a consent or consents in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted and shall be delivered to the Corporation by
delivery to its registered office in the state of incorporation, its principal
place of business, or an officer or agent of the Corporation having custody of
the book in which proceedings of meetings of stockholders are recorded. Delivery
made to the Corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested.

        Every written consent shall bear the date of signature of each
stockholder who signs the consent, and no written consent shall be effective to
take the corporate action referred to therein unless, within sixty (60) days of
the earliest dated consent delivered in the manner required by this Section to
the Corporation, written consents signed by a sufficient number of holders to
take action are delivered to the Corporation by delivery to its registered
office in the state of incorporation, its principal place of business, or an
officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to the
Corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested.

        Prompt notice of the taking of corporation action without a meeting by
less than a unanimous written consent shall be given by the Secretary to those

        Subsequent to the Offering, any action required or permitted to be taken
by the Stockholders must be effected at a duly called annual or special meeting
of Stockholders and may not be effected without such a meeting by any consent in
writing by such holders.

                                   ARTICLE II
                               BOARD OF DIRECTORS

        SECTION 1. NUMBER AND TERM OF OFFICE. The business and affairs of the
Corporation shall be managed by or under the direction of a Board of Directors,
none of whom need be stockholders of the Corporation. The number of Directors
constituting the Board of Directors shall be fixed from time to time by
resolution passed by a majority of the Board of Directors. The Directors shall,
except as hereinafter otherwise provided for filling vacancies or as otherwise
provided in the Certificate of Incorporation, be elected at the annual meeting
of stockholders, and shall hold office until their respective successors are
elected and qualified or until their earlier resignation or removal.

                                       -7-

        SECTION 2. REMOVAL, VACANCIES AND ADDITIONAL DIRECTORS. Except as
otherwise provided in the Certificate of Incorporation, the stockholders may, at
any special meeting the notice of which shall state that it is called for that
purpose, remove, with or without cause, any Director and fill the vacancy;
provided that whenever any Director shall have been elected by the holders of
any class of stock of the Corporation voting separately as a class under the
provisions of the Certificate of Incorporation, such Director may be removed and
the vacancy filled only by the holders of that class of stock voting separately
as a class. Except as otherwise provided in the Certificate of Incorporation,
vacancies caused by any such removal and not filled by the stockholders at the
meeting at which such removal shall have been made, or any vacancy caused by the
death or resignation of any Director or for any other reason, and any newly
created directorship resulting from any increase in the authorized number of
Directors, may be filled by the affirmative vote of a majority of the Directors
then in office, although less than a quorum, and any Director so elected to fill
any such vacancy or newly created directorship shall hold office until his
successor is elected and qualified or until his earlier resignation or removal.

        When one or more Directors shall resign effective at a future date, a
majority of the Directors then in office, including those who have so resigned,
shall have power to fill such vacancy or vacancies, the vote thereon to take
effect when such resignation or resignations shall become effective, and each
Director so chosen shall hold office as herein provided in connection with the
filling of other vacancies.

        SECTION 3. PLACE OF MEETING. The Board of Directors may hold its
meetings in such place or places in the State of Delaware or outside the State
of Delaware as the Board from time to time shall determine.

        SECTION 4. REGULAR MEETINGS. Regular meetings of the Board of Directors
shall be held at such times and places as the Board from time to time by
resolution shall determine. No notice shall be required for any regular meeting
of the Board of Directors; but a copy of every resolution fixing or changing the
time or place of regular meetings shall be mailed to every Director at least
five (5) days before the first meeting held in pursuance thereof.

        SECTION 5. SPECIAL MEETINGS. Special meetings of the Board of Directors
shall be held whenever called by direction of the Chairman of the Board, the
Vice Chairman of the Board, the President or by any two of the Directors then in
office.

        Notice of the day, hour and place of holding of each special meeting
shall be given by mailing the same at least two (2) days before the meeting or
by causing the same to be transmitted by telegraph, cable or wireless at least
one day before the meeting to each Director. Unless otherwise indicated in the
notice thereof, any and all business other than an amendment of these Bylaws may
be transacted at any special meeting, and an amendment of these Bylaws may be
acted upon if the

                                       -8-

notice of the meeting shall have stated that the amendment of these Bylaws is
one of the purposes of the meeting. At any meeting at which every Director shall
be present, even though without any notice, any business may be transacted,
including the amendment of these Bylaws.

        SECTION 6. QUORUM. Subject to the provisions of Section 2 of this
Article II, a majority of the members of the Board of Directors in office (but,
unless the Board shall consist solely of one Director, in no case less than
one-third of the total number of Directors nor less than two Directors) shall
constitute a quorum for the transaction of business and the vote of the majority
of the Directors present at any meeting of the Board of Directors at which a
quorum is present shall be the act of the Board of Directors. If at any meeting
of the Board there is less than a quorum present, a majority of those present
may adjourn the meeting from time to time.

        SECTION 7. ORGANIZATION. The Chairman of the Board, or in his absence,
the Vice Chairman of the Board, or in his absence, the President shall preside
at all meetings of the Board of Directors. In the absence of the Chairman of the
Board, the Vice Chairman of the Board and the President, a Chairman shall be
elected from the Directors present. The Secretary of the Corporation shall act
as Secretary of all meetings of the Directors; but in the absence of the
Secretary, the Chairman may appoint any person to act as Secretary of the
meeting.

        SECTION 8. COMMITTEE. The Board of Directors may, by resolution passed
by a majority of the whole Board, designate one or more committees, each
committee to consist of one or more of the Directors of the Corporation. The
Board may designate one or more Directors as alternate members of any committee,
who may replace any absent or disqualified member at any meeting of the
committee. In the absence or disqualification of a member of a committee, the
member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member. Any such committee, to the extent
provided by resolution passed by a majority of the whole Board, shall have and
may exercise all the powers and authority of the Board of Directors in the
management of the business and the affairs of the Corporation, and may authorize
the seal of the Corporation to be affixed to all papers which may require it;
but no such committee shall have the power or authority in reference to amending
the Certificate of Incorporation, adopting an agreement of merger or
consolidation, recommending to the stockholders the sale, lease or exchange of
all or substantially all of the Corporation's property and assets, recommending
to the stockholders a dissolution of the Corporation or a revocation of a
dissolution, or amending these Bylaws; and unless such resolution, these Bylaws,
or the Certificate of Incorporation expressly so provide, no such committee
shall have the power or authority to declare a dividend or to authorize the
issuance of stock.

        SECTION 9. CONFERENCE TELEPHONE MEETINGS. Unless otherwise restricted by
the Certificate of Incorporation or by these Bylaws, the members of the Board of
Directors or any

                                       -9-

committee designated by the Board, may participate in a meeting of the Board or
such committee, as the case may be, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation shall constitute presence in
person at such meeting.

        SECTION 10. CONSENT OF DIRECTORS OR COMMITTEE IN LIEU OF MEETING. Unless
otherwise restricted by the Certificate of Incorporation or by these Bylaws, any
action required or permitted to be taken at any meeting of the Board of
Directors, or of any committee thereto, may be taken without a meeting if all
members of the Board or committee, as the case may be, consent thereto in
writing and the writing or writings are filed with the minutes of proceedings of
the Board or committee, as the case may be.

                                   ARTICLE III
                                    OFFICERS

        SECTION 1. OFFICERS. The officers of the Corporation shall be a Chairman
of the Board, a Vice Chairman of the Board, a President, one or more Vice
Presidents, a Secretary and a Treasurer, and such additional officers, if any,
as shall be elected by the Board of Directors pursuant to the provisions of
Section 8 of this Article III. The Chairman of the Board, the Vice Chairman of
the Board, the President, one or more Vice Presidents, the Secretary and the
Treasurer shall be elected by the Board of Directors at its first meeting after
each annual meeting of the stockholders. The failure to hold such election shall
not of itself terminate the term of office of any officer. All officers shall
hold office at the pleasure of the Board of Directors. Any officer may resign at
any time upon written notice to the Corporation. Officers may, but need not, be
Directors. Any number of offices may be held by the same person.

        All officers, agents and employees shall be subject to removal, with or
without cause, at any time by the Board of Directors. The removal of an officer
without cause shall be without prejudice to his contract rights, if any. The
election or appointment of an officer shall not of itself create contract
rights. All agents and employees other than officers elected by the Board of
Directors shall also be subject to removal, with or without cause, at any time
by the officers appointing them.

        Any vacancy caused by the death of any officer, his resignation, his
removal, or otherwise, may be filled by the Board of Directors, and any officer
so elected shall hold office at the pleasure of the Board of Directors.

        In addition to the powers and duties of the officers of the Corporation
as set forth in these Bylaws, the officers shall have such authority and shall
perform such duties as from time to time may be determined by the Board of
Directors.

                                      -10-

perform all duties incident to the office of Vice Chairman of the Board. In the
absence of the Chairman of the Board, he shall preside at all meetings of the
stockholders and at all meetings of the Board of Directors and shall have such
other powers and perform such other duties as may from time to time be assigned
to him by these Bylaws or by the Board of Directors or the Chairman of the
Board.

        SECTION 4. POWERS AND DUTIES OF THE PRESIDENT. The President shall be
the chief operating officer of the Corporation and, subject to the control of
the Board of Directors, the Chairman of the Board and the Vice Chairman of the
Board, shall have general charge and control of all its operations and shall
have all powers and shall perform all duties incident to the office of

by the Board of Directors, the Chairman of the Board or the Vice Chairman of the
Board.

        SECTION 5. POWERS AND DUTIES OF THE VICE PRESIDENTS. Each Vice President

        SECTION 6. POWERS AND DUTIES OF THE SECRETARY. The Secretary shall keep
the minutes of all meetings of the Board of Directors and the minutes of all
meetings of the stockholders in books provided for that purpose; he shall attend
to the giving or serving of all notices of the Corporation; he shall have
custody of the corporate seal of the Corporation and shall affix the same to
such documents and other papers as the Board of Directors or the President shall
authorize and direct; he shall have charge of the stock certificate books,
transfer books and stock ledgers and such other books and papers as the Board of
Directors or the President shall direct, all of which shall at all

                                      -11-

reasonable times be open to the examination of any Director, upon application,
at the office of the Corporation during business hours; and whenever required by
the Board of Directors, the Chairman of the Board, the Vice Chairman of the
Board or the President shall render statements of such accounts; and he shall
have all powers and shall perform all duties incident to the office of Secretary
and shall also have such other powers and shall perform such other duties as may
from time to time be assigned to him by these Bylaws or by the Board of
Directors, the Chairman of the Board, the Vice Chairman of the Board or the

the President shall render statements of such accounts; he shall, at all
reasonable times, exhibit his books and accounts to any Director of the

such other duties as may from time to time be assigned to him by these Bylaws or
by the Board of Directors, the Chairman of the Board, the Vice Chairman of the

        SECTION 8. ADDITIONAL OFFICERS. The Board of Directors may from time to
time elect such other officers (who may but need not be Directors), including a

Directors may from time to time, by resolution, confer like powers upon any
other person or persons.

        SECTION 11. COMPENSATION OF OFFICERS. The officers of the Corporation

                                   ARTICLE IV
                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

        SECTION 1. NATURE OF INDEMNITY. The Corporation shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was or has agreed to become a Director or officer of the Corporation, or is or
was serving or has agreed to serve at the request of the Corporation as a
Director or officer of another corporation, partnership, joint venture, trust or
other enterprise, or by reason of any action alleged to have been taken or
omitted in such capacity, and may indemnify any person who was or is a party or
is threatened to be made a party to such an action, suit or proceeding by reason
of the fact that he is or was or has agreed to become an employee or agent of
the Corporation, or is or was serving or has agreed to serve at the request of
the Corporation as an employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or on his behalf in connection with such action, suit or
proceeding and any appeal therefrom, if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful; except that in the case of
an action or suit by or in the right of the Corporation to procure a judgment in
its favor (1) such indemnification shall be limited to expenses (including
attorneys' fees) actually and reasonably incurred by such person in the defense
or settlement of such action or suit, and (2) no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Delaware Court of Chancery or the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Delaware Court of
Chancery or such other court shall deem proper.

                                      -13-

        The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Corporation, and, with respect to any criminal action
or proceeding, had reasonable cause to believe that his conduct was unlawful.

        SECTION 2. SUCCESSFUL DEFENSE. To the extent that a Director, officer,
employee or agent of the Corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in Section 1
of this Article IV or in defense of any claim, issue or matter therein, he shall
be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.

        SECTION 3. DETERMINATION THAT INDEMNIFICATION IS PROPER. Any
indemnification of a Director or officer of the Corporation under Section 1 of
this Article IV (unless ordered by a court) shall be made by the Corporation
unless a determination is made that indemnification of the Director or officer
is not proper in the circumstances because he has not met the applicable
standard of conduct set forth in Section 1. Any indemnification of an employee
or agent of the Corporation under Section 1 (unless ordered by a court) may be
made by the Corporation upon a determination that indemnification of the
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Section 1. Any such determination
shall be made (1) by the Board of Directors by a majority vote of a quorum
consisting of Directors who were not parties to such action, suit or proceeding,
or (2) if such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested Directors so directs, by independent legal counsel in a written
opinion, or (3) by the stockholders.

        SECTION 4. ADVANCE PAYMENT OF EXPENSES. Unless the Board of Directors
otherwise determines in a specific case, expenses incurred by a Director or
officer in defending a civil or criminal action, suit or proceeding shall be
paid by the Corporation in advance of the final disposition of such action, suit
or proceeding upon receipt of an undertaking by or on behalf of the Director or
officer to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation as authorized in this Article IV.
Such expenses incurred by other employees and agents may be so paid upon such
terms and conditions, if any, as the Board of Directors deems appropriate. The
Board of Directors may authorize the Corporation's legal counsel to represent
such Director, officer, employee or agent in any action, suit or proceeding,
whether or not the Corporation is a party to such action, suit or proceeding.

        SECTION 5. SURVIVAL; PRESERVATION OF OTHER RIGHTS. The foregoing
indemnification provisions shall be deemed to be a contract between the
Corporation and each Director, officer, employee and agent who serves in any
such capacity at any time while these provisions as well as the relevant
provisions of the Delaware General Corporation Law are in effect and any repeal
or

                                      -14-

modification thereof shall not affect any right or obligation then existing with
respect to any state of facts then or previously existing or any action, suit,
or proceeding previously or thereafter brought or threatened based in whole or
in part upon any such state of facts. Such a contract right may not be modified
retroactively without the consent of such Director, officer, employee or agent.

        The indemnification provided by this Article IV shall not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any bylaw, agreement, vote of stockholders or disinterested Directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be a Director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person. The
Corporation may enter into an agreement with any of its Directors, officers,
employees or agents providing for indemnification and advancement of expenses,
including attorneys fees, that may change, enhance, qualify or limit any right
to indemnification or advancement of expenses created by this Article IV.

        SECTION 6. SEVERABILITY. If this Article IV or any portion hereof shall
be invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Director or officer and may
indemnify each employee or agent of the Corporation as to costs, charges and
expenses (including attorneys' fees), judgment, fines and amounts paid in
settlement with respect to any action, suit or proceeding, whether civil,
criminal, administrative or investigative, including an action by or in the
right of the Corporation, to the fullest extent permitted by any applicable
portion of this Article IV that shall not have been invalidated and to the
fullest extent permitted by applicable law.

        SECTION 7. SUBROGATION. In the event of payment of indemnification to a
person described in Section 1 of this Article IV, the Corporation shall be
subrogated to the extent of such payment to any right of recovery such person
may have and such person, as a condition of receiving indemnification from the
Corporation, shall execute all documents and do all things that the Corporation
may deem necessary or desirable to perfect such right of recovery, including the
execution of such documents necessary to enable the Corporation effectively to
enforce any such recovery.

        SECTION 8. NO DUPLICATION OF PAYMENTS. The Corporation shall not be
liable under this Article IV to make any payment in connection with any claim
made against a person described in Section 1 of this Article IV to the extent
such person has otherwise received payment (under any insurance policy, bylaw or
otherwise) of the amounts otherwise indemnifiable hereunder.

                                    ARTICLE V
                             STOCK-SEAL-FISCAL YEAR

                                      -15-

        SECTION 1. CERTIFICATES FOR SHARES OF STOCK. The certificates for shares
of stock of the Corporation shall be in such form, not inconsistent with the
Certificate of Incorporation, as shall be approved by the Board of Directors.
All certificates shall be signed by the Chairman of the Board, the Vice Chairman
of the Board, the President or a Vice President and by the Secretary or an
Assistant Secretary or the Treasurer or an Assistant Treasurer, and shall not be
valid unless so signed.

        In case any officer or officers who shall have signed any such
certificate or certificates shall cease to be such officer or officers of the
Corporation, whether because of death, resignation or otherwise, before such
certificate or certificates shall have been delivered by the Corporation, such
certificate or certificates may nevertheless be issued and delivered as though
the person or persons who signed such certificate or certificates had not ceased
to be such officer or officers of the Corporation.

        All certificates for shares of stock shall be consecutively numbered as
the same are issued. The name of the person owning the shares represented
thereby with the number of such shares and the date of issue thereof shall be
entered on the books of the Corporation.

        Except as hereinafter provided, all certificates surrendered to the
Corporation for transfer shall be canceled, and no new certificates shall be
issued until former certificates for the same number of shares have been
surrendered and canceled.

        SECTION 2. LOST, STOLEN OR DESTROYED CERTIFICATES. Whenever a person
owning a certificate for shares of stock of the Corporation alleges that it has
been lost, stolen or destroyed, he shall file in the office of the Corporation
an affidavit setting forth, to the best of his knowledge and belief, the time,
place and circumstances of the loss, theft or destruction, and, if required by
the Board of Directors, a bond of indemnity or other indemnification sufficient
in the opinion of the Board of Directors to indemnify the Corporation and its
agents against any claim that may be made against it or them on account of the
alleged loss, theft or destruction of any such certificate or the issuance of a
new certificate in replacement therefor. Thereupon the Corporation may cause to
be issued to such person a new certificate in replacement for the certificate
alleged to have been lost, stolen or destroyed. Upon the stub of every new
certificate so issued shall be noted the fact of such issue and the number, date
and the name of the registered owner of the lost, stolen or destroyed
certificate in lieu of which the new certificate is issued.

        SECTION 3. TRANSFER OF SHARES. Shares of stock of the Corporation shall
be transferred on the books of the Corporation by the holder thereof, in person
or by his attorney duly authorized in writing, upon surrender and cancellation
of certificates for the number of shares of stock to be transferred, except as
provided in Section 2 of this Article IV.

                                      -16-

        SECTION 4. REGULATIONS. The Board of Directors shall have power and
authority to make such rules and regulations as it may deem expedient concerning
the issue, transfer and registration of certificates for shares of stock of the
Corporation.

        SECTION 5. RECORD DATE. In order that the Corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or to express consent to corporate action in writing
without a meeting or to receive payment of any dividend or other distribution or
allotment of any rights, or to exercise any rights in respect of any change,
conversion or exchange of stock or for the purpose of any other lawful action,
as the case may be, the Board of Directors may fix, in advance, a record date,
which shall not be (i) more than sixty (60) nor less than ten (10) days before
the date of such meeting, or (ii) in the case of corporate action to be taken by
consent in writing without a meeting prior to, or more than ten (10) days after,
the date upon which the resolution fixing the record date is adopted by the
Board of Directors, or (iii) more than sixty (60) days prior to any other
action.

        If no record date is fixed, the record date for determining stockholders
entitled to notice of or to vote at a meeting of stockholders shall be at the
close of business on the day next preceding the day on which notice is given or,
if notice is waived, at the close of business on the day next preceding the day
on which the meeting is held; the record date for determining stockholders
entitled to express consent to corporate action in writing without a meeting,
when no prior action by the Board of Directors is necessary, shall be the day on
which the first written consent is delivered to the Corporation; and the record
date for determining stockholders for any other purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolution
relating thereto. A determination of stockholders of record entitled to notice
of or to vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board of Directors may fix a new record
date for the adjourned meeting.

        SECTION 6. DIVIDENDS. Subject to the provisions of the Certificate of
Incorporation, the Board of Directors shall have power to declare and pay
dividends upon shares of stock of the Corporation, but only out of funds
available for the payment of dividends as provided by law.

        Subject to the provisions of the Certificate of Incorporation, any
dividends declared upon the stock of the Corporation shall be payable on such
date or dates as the Board of Directors shall determine. If the date fixed for
the payment of any dividend shall in any year fall upon a legal holiday, then
the dividend payable on such date shall be paid on the next day not a legal

Committee. The Committee shall have full and final authority to take the
following actions, in each case subject to and consistent with the provisions of
the Plan:

            (i) to select persons to whom Awards may be granted;

            (ii) to determine the type or types of Awards to be granted to each
such person;

                                    -3-

            (iii) to determine the number of Awards to be granted, the number of
shares of Stock to which an Award will relate, the terms and conditions of any
Award granted under the Plan (including, but not limited to, any exercise price,
grant price or purchase price, any restriction or condition, any schedule for
lapse of restrictions or conditions relating to transferability or forfeiture,
exercisability or settlement of an Award, and waivers or accelerations thereof,
performance conditions relating to an Award (including performance conditions
relating to Awards not intended to be governed by Section 7(f) and waivers and
modifications thereof), based in each case on such considerations as the
Committee shall determine), and all other matters to be determined in connection
with an Award;

            (iv) to determine whether, to what extent and under what
circumstances an Award may be settled, or the exercise price of an Award may be
paid, in cash, Stock, other Awards, or other property, or an Award may be
canceled, forfeited, or surrendered;

            (v) to determine whether, to what extent and under what
circumstances cash, Stock, other Awards or other property payable with respect
to an Award will be deferred either automatically, at the election of the
Committee or at the election of the Participant;

            (vi) to prescribe the form of each Award Agreement, which need not
be identical for each Participant;

            (vii) to adopt, amend, suspend, waive and rescind such rules and
regulations and appoint such agents as the Committee may deem necessary or
advisable to administer the Plan;

            (viii) to correct any defect or supply any omission or reconcile any
inconsistency in the Plan and to construe and interpret the Plan and any Award,
rules and regulations, Award Agreement or other instrument hereunder; and

            (ix) to make all other decisions and determinations as may be
required under the terms of the Plan or as the Committee may deem necessary or
advisable for the administration of the Plan.

      (b) MANNER OF EXERCISE OF COMMITTEE AUTHORITY. Unless authority is
specifically reserved to the Board under the terms of the Plan, the Company's
Certificate of Incorporation or Bylaws, or applicable law, the Committee shall
have sole discretion in exercising authority under the Plan. Any action of the
Committee with respect to the Plan shall be final, conclusive and binding on all
persons, including the Company, subsidiaries of the Company, Participants, any
person claiming any rights under the Plan from or through any Participant and
stockholders, except to the extent the Committee may subsequently modify, or
take further action

                                    -4-

not consistent with, its prior action. If not specified in the Plan, the time at
which the Committee must or may make any determination shall be determined by
the Committee, and any such determination may thereafter by modified by the
Committee (subject to Section 8(e)). The express grant of any specific power to
the Committee, and the taking of any action by the Committee, shall not be
construed as limiting any power or authority of the Committee. The Committee may
delegate to officers or managers of the Company or any subsidiary of the Company
the authority, subject to such terms as the Committee shall determine, to
perform administrative functions and, with respect to Participants not subject
to Section 16 of the Exchange Act, to perform such other functions as the
Committee may determine, to the extent permitted under Rule 16b-3, if
applicable, and other applicable law.

      (c) LIMITATION OF LIABILITY. Each member of the Committee shall be
entitled to, in good faith, rely or act upon any report or other information
furnished to him by any officer or other employee of the Company or any
subsidiary, the Company's independent certified public accountants or any
executive compensation consultant, legal counsel or other professional retained
by the Company to assist in the administration of the Plan. No member of the
Committee, nor any officer or employee of the Company acting on behalf of the
Committee, shall be personally liable for any action, determination or
interpretation taken or made in good faith with respect to the Plan, and all
members of the Committee and any officer or employee of the Company acting on
its behalf shall, to the extent permitted by law, be fully indemnified and
protected by the Company with respect to any such action, determination or
interpretation.

      4.    STOCK SUBJECT TO PLAN.

      (a) AMOUNT OF STOCK RESERVED. The total amount of Stock that may be
subject to outstanding awards, determined immediately after the grant of any
Award, shall not exceed the greater of 2,500,000 shares of Stock or 13% of the
total number of shares of Stock outstanding at the time of such grant.
Notwithstanding the foregoing, the number of shares that may be delivered upon
the exercise of ISOs shall not exceed 500,000, subject in each case to
adjustment as provided in Section 4(c), and the number of shares that may be
delivered as Restricted Stock and Deferred Stock (other than pursuant to an
Award granted under Section 7(f)) shall not in the aggregate exceed 500,000,
provided, however, that shares subject to ISOs, Restricted Stock or Deferred
Stock Awards shall not be deemed delivered if such Awards are forfeited, expire
or otherwise terminate without delivery of shares to the Participant. To the
extent that an Award is only to be paid in cash or is paid in cash, any shares
of Stock subject to such Award shall again be available for the grant of an
Award. Any shares of Stock delivered pursuant to an Award may consist, in whole
or in part, of authorized and unissued shares, treasury shares or shares
acquired in the market for a Participant's Account.

                                    -5-

      (b) ANNUAL PER-PARTICIPANT LIMITATIONS. During any calendar year, no
Participant may be granted Awards that may be settled by delivery of more than
250,000 shares of Stock, subject to adjustment as provided in Section 4(c). In
addition, with respect to Awards that may be settled in cash (in whole or in
part), no Participant may be paid during any calendar year cash amounts relating
to such Awards that exceed the greater of the Fair Market Value of the number of
shares of Stock set forth in the preceding sentence at the date of grant or the
date of settlement of Award. This provision sets forth two separate limitations,
so that Awards that may be settled solely by delivery of Stock will not operate
to reduce the amount of cash-only Awards, and vice versa; nevertheless, Awards
that may be settled in Stock or cash must not exceed either limitation.

      (c) ADJUSTMENTS. In the event that the Committee shall determine that any
dividend or other distribution (whether in the form of cash, Stock or other
property), recapitalization, forward or reverse split, reorganization, merger,
consolidation, spin-off, combination, repurchase or exchange of Stock or other
securities, liquidation, dissolution, or other similar corporate transaction or
event, affects the Stock such that an adjustment is appropriate in order to
prevent dilution or enlargement of the rights of Participants under the Plan,
then the Committee shall, in such manner as it may deem equitable, adjust any or
all of (i) the number and kind of shares of Stock reserved and available for
Awards under Section 4(a), including shares reserved for the ISOs and Restricted
and Deferred Stock, (ii) the number and kind of shares of Stock specified in the
Annual Per-Participant Limitations under Section 4(b), (iii) the number and kind
of shares of outstanding Restricted Stock or other outstanding Award in
connection with which shares have been issued, (iv) the number and kind of
shares that may be issued in respect of other outstanding Awards and (v) the
exercise price, grant price or purchase price relating to any Award (or, if
deemed appropriate, the Committee may make provision for a cash payment with
respect to any outstanding Award). In addition, the Committee is authorized to
make adjustments in the terms and conditions of, and the criteria included in,
Awards in recognition of unusual or nonrecurring events (including, without
limitation, events described in the preceding sentence) affecting the Company or
any subsidiary or the financial statements of the Company or any subsidiary, or
in response to changes in applicable laws, regulations, or accounting
principles. The foregoing notwithstanding, no adjustments shall be authorized
under this Section 4(c) with respect to ISOs or SARs in tandem therewith to the
extent that such authority would cause the Plan to fail to comply with Section
422(b)(1) of the Code, and no such adjustment shall be authorized with respect
to Options, SARs or other Awards subject to Section 7(f) to the extent that such
authority would cause such Awards to fail to qualify as "qualified
performance-based compensation" under Section 162(m)(4)(C) of the Code.

      5. ELIGIBILITY. Executive officers and other key employees of the Company
and its subsidiaries, including any director or officer who is also such an
employee, and persons who provide consulting or other services to the Company
deemed by the Committee to be of substantial value to the Company, are eligible
to be granted Awards under the Plan. In addition, a person who

                                    -6-

has been offered employment by the Company or its subsidiaries is eligible to be
granted an Award under the Plan, provided that such Award shall be cancelled if
such person fails to commence such employment, and no payment of value may be
made in connection with such Award until such person has commenced such
employment. The foregoing notwithstanding, no member of the Committee shall be
eligible to be granted Awards under the Plan.

      6.    SPECIFIC TERMS OF AWARDS.

      (a) GENERAL. Awards may be granted on the terms and conditions set forth
in this Section 6. In addition, the Committee may impose on any Award or the
exercise thereof such additional terms and conditions, not inconsistent with the
provisions of the Plan, as the Committee shall determine, including terms
requiring forfeiture of Awards in the event of termination of employment or
service of the Participant. Except as provided in Section 6(f), 6(h), or 7(a),
or to the extent required to comply with requirements of the Delaware General
Corporation Law that lawful consideration be paid for Stock, only services may
be required as consideration for the grant (but not the exercise) of any Award.

      (b) OPTIONS. The Committee is authorized to grant Options (including
"reload" options automatically granted to offset specified exercises of Options)
on the following terms and conditions ("Options"):

            (i) EXERCISE PRICE. The exercise price per share of Stock
purchasable under an Option shall be determined by the Committee; PROVIDED,
HOWEVER, that, except as provided in Section 7(a), such exercise price shall be
not less than the Fair Market Value of a share on the date of grant of such
Option.

            (ii) TIME AND METHOD OF EXERCISE. The Committee shall determine the
time or times at which an Option may be exercised in whole or in part, the
methods by which such exercise price may be paid or deemed to be paid, the form
of such payment, including, without limitation, cash, Stock, other Awards or
awards granted under other Company plans or other property (including notes or
other contractual obligations of Participants to make payment on a deferred
basis, such as through "cashless exercise" arrangements, to the extent permitted
by applicable law), and the methods by which Stock will be delivered or deemed
to be delivered to Participants.

            (iii) ISOS. The terms of any ISO granted under the Plan shall comply
in all respects with the provisions of Section 422 of the Code, including but
not limited to the requirement that no ISO shall be granted more than ten years
after the effective date of the Plan. Anything in the Plan to the contrary
notwithstanding, no term of the Plan relating to ISOs shall be interpreted,

                                    -7-

amended, or altered, nor shall any discretion or authority granted under the
Plan be exercised, so as to disqualify either the Plan or any ISO under Section
422 of the Code, unless requested by the affected Participant.

            (iv) TERMINATION OF EMPLOYMENT. Unless otherwise determined by the
Committee, upon termination of a Participant's employment with the Company and
its subsidiaries, such Participant may exercise any Options during the
three-month period following such termination of employment, but only to the
extent such Option was exercisable immediately prior to such termination of
employment. Notwithstanding the foregoing, if the Committee determines that such
termination is for cause, all Options held by the Participant shall terminate as
of the termination of employment.

      (c) STOCK APPRECIATION RIGHTS. The Committee is authorized to grant SARs
on the following terms and conditions ("SARs"):

            (i) RIGHT TO PAYMENT. An SAR shall confer on the Participant to whom
it is granted a right to receive, upon exercise thereof, the excess of (A) the
Fair Market Value of one share of Stock on the date of exercise (or, if the
Committee shall so determine in the case of any such right other than one
related to an ISO, the Fair Market Value of one share at any time during a
specified period before or after the date of exercise), over (B) the grant price
of the SAR as determined by the Committee as of the date of grant of the SAR,
which, except as provided in Section 7(a), shall be not less than the Fair
Market Value of one share of Stock on the date of grant.

            (ii) OTHER TERMS. The Committee shall determine the time or times at
which an SAR may be exercised in whole or in part, the method of exercise,
method of settlement, form of consideration payable in settlement, method by
which Stock will be delivered or deemed to be delivered to Participants, whether
or not an SAR shall be in tandem with any other Award, and any other terms and
conditions of any SAR. Limited SARs that may only be exercised upon the
occurrence of a Change in Control may be granted on such terms, not inconsistent
with this Section 6(c), as the Committee may determine. Limited SARs may be
either freestanding or in tandem with other Awards.

      (d) RESTRICTED STOCK. The Committee is authorized to grant Restricted
Stock on the following terms and conditions ("Restricted Stock"):

            (i) GRANT AND RESTRICTIONS. Restricted Stock shall be subject to
such restrictions on transferability and other restrictions, if any, as the
Committee may impose, which restrictions may lapse separately or in combination
at such times, under such circumstances, in such

                                    -8-

installments, or otherwise, as the Committee may determine. Except to the extent
restricted under the terms of the Plan and any Award Agreement relating to the
Restricted Stock, a Participant granted Restricted Stock shall have all of the
rights of a stockholder including, without limitation, the right to vote
Restricted Stock or the right to receive dividends thereon.

            (ii) FORFEITURE. Except as otherwise determined by the Committee,
upon termination of employment or service (as determined under criteria
established by the Committee) during the applicable restriction period,
Restricted Stock that is at that time subject to restrictions shall be forfeited
and reacquired by the Company; PROVIDED, HOWEVER, that the Committee may
provide, by rule or regulation or in any Award Agreement, or may determine in
any individual case, that restrictions or forfeiture conditions relating to
Restricted Stock will be waived in whole or in part in the event of termination
resulting from specified causes.

            (iii) CERTIFICATES FOR STOCK. Restricted Stock granted under the
Plan may be evidenced in such manner as the Committee shall determine. If
certificates representing Restricted Stock are registered in the name of the
Participant, such certificates may bear an appropriate legend referring to the
terms, conditions, and restrictions applicable to such Restricted Stock, the
Company may retain physical possession of the certificate, and the Participant
shall have delivered a stock power to the Company, endorsed in blank, relating
to the Restricted Stock.

            (iv) DIVIDENDS. Dividends paid on Restricted Stock shall be either
paid at the dividend payment date in cash or in shares of unrestricted Stock
having a Fair Market Value equal to the amount of such dividends, or the payment
of such dividends shall be deferred and/or the amount or value thereof
automatically reinvested in additional Restricted Stock, other Awards, or other
investment vehicles, as the Committee shall determine or permit the Participant
to elect. Stock distributed in connection with a Stock split or Stock dividend,
and other property distributed as a dividend, shall be subject to restrictions
and a risk of forfeiture to the same extent as the Restricted Stock with respect
to which such Stock or other property has been distributed, unless otherwise
determined by the Committee.

      (e) DEFERRED STOCK. The Committee is authorized to grant Deferred Stock
subject to the following terms and conditions ("Deferred Stock"):

            (i)   AWARD AND RESTRICTIONS.  Delivery of Stock will occur upon
expiration of the deferral period specified for an Award of Deferred Stock by
the Committee (or, if permitted by the Committee, as elected by the
Participant). In addition, Deferred Stock shall be subject to such restrictions
as the Committee may impose, if any, which restrictions may lapse at the
expiration of the deferral period or at earlier specified times, separately or
in combination, in installments or otherwise, as the Committee may determine.

                                    -9-

            (ii) FORFEITURE. Except as otherwise determined by the Committee,
upon termination of employment or service (as determined under criteria
established by the Committee) during the applicable deferral period or portion
thereof to which forfeiture conditions apply (as provided in the Award Agreement
evidencing the Deferred Stock), all Deferred Stock that is at that time subject
to such forfeiture conditions shall be forfeited; PROVIDED, HOWEVER, that the
Committee may provide, by rule or regulation or in any Award Agreement, or may
determine in any individual case, that restrictions or forfeiture conditions
relating to Deferred Stock will be waived in whole or in part in the event of
termination resulting from specified causes.

      (f)   BONUS STOCK AND AWARDS IN LIEU OF CASH OBLIGATIONS.  The
Committee is authorized to grant Stock as a bonus, or to grant Stock or other
Awards in lieu of Company obligations to pay cash under other plans or
compensatory arrangements. Stock or Awards granted hereunder shall be subject to
such other terms as shall be determined by the Committee.

      (g)   DIVIDEND EQUIVALENTS.  The Committee is authorized to grant Dividend
Equivalents entitling the Participant to receive cash, Stock, other Awards or
other property equal in value to dividends paid with respect to a specified
number of shares of Stock ("Dividend Equivalents"). Dividend Equivalents may be
awarded on a free-standing basis or in connection with another Award. The
Committee may provide that Dividend Equivalents shall be paid or distributed
when accrued or shall be deemed to have been reinvested in additional Stock,
Awards or other investment vehicles, and subject to such restrictions on
transferability and risks of forfeiture, as the Committee may specify.

      (h) OTHER STOCK-BASED AWARDS. The Committee is authorized, subject to
limitations under applicable law, to grant such other Awards that may be
denominated or payable in, valued in whole or in part by reference to, or
otherwise based on, or related to, Stock and factors that may influence the
value of Stock, as deemed by the Committee to be consistent with the purposes of
the Plan, including, without limitation, convertible or exchangeable debt
securities, other rights convertible or exchangeable into Stock, purchase rights
for Stock, Awards with value and payment contingent upon performance of the
Company or any other factors designated by the Committee and Awards valued by
reference to the book value of Stock or the value of securities of or the
performance of specified subsidiaries ("Other Stock Based Awards"). The
Committee shall determine the terms and conditions of such Awards. Stock issued
pursuant to an Award in the nature of a purchase right granted under this
Section 6(h) shall be purchased for such consideration, paid for at such times,
by such methods, and in such forms, including, without limitation, cash, Stock,
other Awards, or other property, as the Committee shall determine. Cash awards,
as an element of or supplement to any other Award under the Plan, may be granted
pursuant to this Section 6(h).

                                    -10-

      7.    CERTAIN PROVISIONS APPLICABLE TO AWARDS.

      (a)   STAND-ALONE, ADDITIONAL, TANDEM, AND SUBSTITUTE AWARDS.
Awards granted under the Plan may, in the discretion of the Committee, be
granted either alone or in addition to, in tandem with or in substitution for
any other Award granted under the Plan or any award granted under any other plan
of the Company, any subsidiary or any business entity to be acquired by the
Company or a subsidiary, or any other right of a Participant to receive payment
from the Company or any subsidiary. Awards granted in addition to or in tandem
with other Awards or awards may be granted either as of the same time as or a
different time from the grant of such other Awards or awards.

      (b) TERM OF AWARDS. The term of each Award shall be for such period as may
be determined by the Committee; PROVIDED, HOWEVER, that in no event shall the
term of any ISO or an SAR granted in tandem therewith exceed a period of seven
years from the date of its grant (or such shorter period as may be applicable
under Section 422 of the Code).

      (c) FORM OF PAYMENT UNDER AWARDS. Subject to the terms of the Plan and any
applicable Award Agreement, payments to be made by the Company or a subsidiary
upon the grant, exercise or settlement of an Award may be made in such forms as
the Committee shall determine, including, without limitation, cash, Stock, other
Awards or other property, and may be made in a single payment or transfer, in
installments or on a deferred basis. Such payments may include, without
limitation, provisions for the payment or crediting of reasonable interest on
installment or deferred payments or the grant or crediting of Dividend
Equivalents in respect of installment or deferred payments denominated in Stock.

      (d) LOAN PROVISIONS. With the consent of the Committee, and subject at all
times to, and only to the extent, if any, permitted under and in accordance
with, laws and regulations and other binding obligations or provisions
applicable to the Company, the Company may make, guarantee or arrange for a loan
or loans to a Participant with respect to the exercise of any Option or other
payment in connection with any Award, including the payment by a Participant of
any or all federal, state or local income or other taxes due in connection with
any Award. Subject to such limitations, the Committee shall have full authority
to decide whether to make a loan or loans hereunder and to determine the amount,
terms and provisions of any such loan or loans, including the interest rate to
be charged in respect of any such loan or loans, whether the loan or loans are
to be with or without recourse against the borrower, the terms on which the loan
is to be repaid and conditions, if any, under which the loan or loans may be
forgiven.

      (e) PERFORMANCE-BASED AWARDS. The Committee may, in its discretion,
designate any Award the exercisability or settlement of which is subject to the
achievement of

                                    -11-

performance conditions as a performance-based Award subject to this Section
7(f), in order to qualify such Award as "qualified performance-based
compensation" within the meaning of Code Section 162(m) and regulations
thereunder. The performance objectives for an Award subject to this Section 7(f)
shall consist of one or more business criteria and a targeted level or levels of
performance with respect to such criteria, as specified by the Committee but
subject to this Section 7(f). Performance objectives shall be objective and
shall otherwise meet the requirements of Section 162(m)(4)(C) of the Code.
Business criteria used by the Committee in establishing performance objectives
for Awards subject to this Section 7(f) shall be selected exclusively from among
the following:

            (1)   Annual return on capital;

            (2)   Annual earnings per share;

            (3)   Annual cash flow provided by operations;

            (4)   Changes in annual revenues; and/or

            (5) Strategic business criteria, consisting of one or more
objectives based on meeting specified revenue, market penetration, geographic
business expansion goals, cost targets, and goals relating to acquisitions or
divestitures.

      The levels of performance required with respect to such business criteria
may be expressed in absolute or relative levels. Achievement of performance
objectives with respect to such Awards shall be measured over a period of not
less than one year nor more than five years, as the Committee may specify.
Performance objectives may differ for such Awards to different Participants. The
Committee shall specify the weighting to be given to each performance objective
for purposes of determining the final amount payable with respect to any such
Award. The Committee may, in its discretion, reduce the amount of a payout
otherwise to be made in connection with an Award subject to this Section 7(f),
but may not exercise discretion to increase such amount, and the Committee may
consider other performance criteria in exercising such discretion. All
determinations by the Committee as to the achievement of performance objectives
shall be in writing. The Committee may not delegate any responsibility with
respect to an Award subject to this Section 7(f).

      (f) ACCELERATION UPON A CHANGE OF CONTROL. Notwithstanding anything
contained herein to the contrary, unless otherwise provided by the Committee in
an Award Agreement, all conditions and restrictions relating to an Award,
including limitations on exercisability, risks of forfeiture and conditions and
restrictions requiring the continued performance

                                    -12-

of services or the achievement of performance objectives with respect to the
exercisability or settlement of such Award, shall immediately lapse upon a
Change in Control.

      8.    GENERAL PROVISIONS.

      (a)   COMPLIANCE WITH LAWS AND OBLIGATIONS. The Company shall not be
obligated to issue or deliver Stock in connection with any Award or take any
other action under the Plan in a transaction subject to the registration
requirements of the Securities Act of 1933, as amended, or any other federal or
state securities law, any requirement under any listing agreement between the
Company and any national securities exchange or automated quotation system or
any other law, regulation or contractual obligation of the Company until the
Company is satisfied that such laws, regulations, and other obligations of the
Company have been complied with in full. Certificates representing shares of
Stock issued under the Plan will be subject to such stop-transfer orders and
other restrictions as may be applicable under such laws, regulations and other
obligations of the Company, including any requirement that a legend or legends
be placed thereon.

      (b) LIMITATIONS ON TRANSFERABILITY. Awards and other rights under the Plan
will not be transferable by a Participant except by will or the laws of descent
and distribution or to a Beneficiary in the event of the Participant's death,
and, if exercisable, shall be exercisable during the lifetime of a Participant
only by such Participant or his guardian or legal representative; PROVIDED,
HOWEVER, that such Awards and other rights (other than ISOs and SARs in tandem
therewith) may be transferred to one or more transferees during the lifetime of
the Participant, and may be exercised by such transferees in accordance with the
terms of such Award consistent with the registration of the offer and sale of
Stock on Form S-8 or Form S-3 or a successor registration form of the Securities
and Exchange Commission, and permitted by the Committee. Awards and other rights
under the Plan may not be pledged, mortgaged, hypothecated or otherwise
encumbered, and shall not be subject to the claims of creditors.

      (c)   NO RIGHT TO CONTINUED EMPLOYMENT OR SERVICE.  Neither the Plan
nor any action taken hereunder shall be construed as giving any employee or
other person the right to be retained in the employ or service of the Company or
any of its subsidiaries, nor shall it interfere in any way with the right of the
Company or any of its subsidiaries to terminate any employee's employment or
other person's service at any time.

      (d) TAXES. The Company and any subsidiary is authorized to withhold from
any Award granted or to be settled, any delivery of Stock in connection with an
Award, any other payment relating to an Award or any payroll or other payment to
a Participant amounts of withholding and other taxes due or potentially payable
in connection with any transaction involving an Award, and to take such other
action as the Committee may deem advisable to enable the Company and

                                    -13-

Participants to satisfy obligations for the payment of withholding taxes and
other tax obligations relating to any Award. This authority shall include
authority to withhold or receive Stock or other property and to make cash
payments in respect thereof in satisfaction of a Participant's tax obligations.

      (e) CHANGES TO THE PLAN AND AWARDS. The Board may amend, alter, suspend,
discontinue or terminate the Plan or the Committee's authority to grant Awards
under the Plan without the consent of stockholders or Participants, except that
any such action shall be subject to the approval of the Company's stockholders
at or before the next annual meeting of stockholders for which the record date
is after such Board action if such stockholder approval is required by any
federal or state law or regulation or the rules of any stock exchange or
automated quotation system on which the Stock may then be listed or quoted, and
the Board may otherwise, in its discretion, determine to submit other such
changes to the Plan to stockholders for approval; PROVIDED, HOWEVER, that,
without the consent of an affected Participant, no such action may materially
impair the rights of such Participant under any Award theretofore granted to
him. The Committee may waive any conditions or rights under, or amend, alter,
suspend, discontinue, or terminate, any Award theretofore granted and any Award
Agreement relating thereto; PROVIDED, HOWEVER, that, without the consent of an
affected Participant, no such action may materially impair the rights of such
Participant under such Award.

      (f)   NO RIGHTS TO AWARDS; NO STOCKHOLDER RIGHTS.  No Participant or
employee shall have any claim to be granted any Award under the Plan, and there
is no obligation for uniformity of treatment of Participants and employees. No
Award shall confer on any Participant any of the rights of a stockholder of the
Company unless and until Stock is duly issued or transferred and delivered to
the Participant in accordance with the terms of the Award or, in the case of an
Option, the Option is duly exercised.

      (g)   UNFUNDED STATUS OF AWARDS; CREATION OF TRUSTS.  The Plan is
intended to constitute an "unfunded" plan for incentive and deferred
compensation. With respect to any payments not yet made to a Participant
pursuant to an Award, nothing contained in the Plan or any Award shall give any
such Participant any rights that are greater than those of a general creditor of
the Company; PROVIDED, HOWEVER, that the Committee may authorize the creation of
trusts or make other arrangements to meet the Company's obligations under the
Plan to deliver cash, Stock, other Awards, or other property pursuant to any
Award, which trusts or other arrangements shall be consistent with the
"unfunded" status of the Plan unless the Committee otherwise determines with the
consent of each affected Participant.

      (h) NONEXCLUSIVITY OF THE PLAN. Neither the adoption of the Plan by the
Board nor its submission to the stockholders of the Company for approval shall
be construed as creating

                                    -14-

any limitations on the power of the Board to adopt such other compensatory
arrangements as it may deem desirable, including, without limitation, the
granting of stock options otherwise than under the Plan, and such arrangements
may be either applicable generally or only in specific cases.

      (i) NO FRACTIONAL SHARES. No fractional shares of Stock shall be issued or
delivered pursuant to the Plan or any Award. The Committee shall determine
whether cash, other Awards, or other property shall be issued or paid in lieu of
such fractional shares or whether such fractional shares or any rights thereto
shall be forfeited or otherwise eliminated.

      (j) COMPLIANCE WITH CODE SECTION 162(M). It is the intent of the Company
that employee Options, SARs and other Awards designated as Awards subject to
Section 7(f) shall constitute "qualified performance-based compensation" within
the meaning of Code Section 162(m). Accordingly, if any provision of the Plan or
any Award Agreement relating to such an Award does not comply or is inconsistent
with the requirements of Code Section 162(m), such provision shall be construed
or deemed amended to the extent necessary to conform to such requirements, and
no provision shall be deemed to confer upon the Committee or any other person
discretion to increase the amount of compensation otherwise payable in
connection with any such Award upon attainment of the performance objectives.

      (k) GOVERNING LAW. The validity, construction and effect of the Plan, any
rules and regulations relating to the Plan and any Award Agreement shall be
determined in accordance with the laws of the State of Delaware, without giving
effect to principles of conflicts of laws, and applicable federal law.

      (l) EFFECTIVE DATE; PLAN TERMINATION. The Plan shall become effective as
of the date of its adoption by the Board, subject to stockholder approval prior
to the commencement of the Initial Public Offering, and shall continue in effect
until terminated by the Board.

                                    -15-

                                                                    EXHIBIT 10.2

                           COMFORT SYSTEMS USA, INC.

      1. PURPOSE. The purpose of this 1997 Non-Employee Directors' Stock Plan
(the "Plan") of Comfort Systems USA, Inc., a Delaware corporation (the
"Company"), is to advance the interests of the Company and its stockholders by
providing a means to attract and retain highly qualified persons to serve as
non-employee directors of the Company and to enable such persons to acquire or
increase a proprietary interest in the Company, thereby promoting a closer
identity of interests between such persons and the Company's stockholders.

      2. DEFINITIONS. In addition to terms defined elsewhere in the Plan, the
following are defined terms under the Plan:

      (a) "Code" means the Internal Revenue Code of 1986, as amended from time
to time. References to any provision of the Code shall be deemed to include
regulations thereunder and successor provisions and regulations thereto.

      (b) "Deferred Share" means a credit to a Participant's deferral account
under Section 7 which represents the right to receive one Share upon settlement
of the deferral account. Deferral accounts, and Deferred Shares credited
thereto, are maintained solely as bookkeeping entries by the Company evidencing
unfunded obligations of the Company.

      (c) "Exchange Act" means the Securities Exchange Act of 1934, as amended.
References to any provision of the Exchange Act shall be deemed to include rules
thereunder and successor provisions and rules thereto.

      (d) "Fair Market Value" of a Share on a given date mean the last sales
price or, if last sales information is generally unavailable, the average of the
closing bid and asked prices per Share on such date (or, if there was no trading
or quotation in the stock on such date, on the next preceding date on which
there was trading or quotation) as reported in the WALL STREET JOURNAL;
PROVIDED, HOWEVER, that the "Fair Market Value" of a Share subject to Options
granted effective on the date on which the Company commences an Initial Public
Offering shall be the price of the shares so issued and sold, as set forth in
the first final prospectus used in such Initial Public Offering.

      (e) "Initial Public Offering" means an initial public offering of shares
in a firm commitment underwriting registered with the Securities and Exchange
Commission in compliance with the provisions of the Securities Act of 1933, as
amended.

      (f) "Option" means the right, granted to a director under Section 6, to
purchase a specified number of Shares at the specified exercise price for a
specified period of time under the Plan. All Options will be non-qualified stock
options.

      (g) "Participant" means a person who, as a non-employee director of the
Company, has been granted an Option or Deferred Shares which remain outstanding
or who has elected to be paid fees in the form of Shares or Deferred Shares
under the Plan.

      (h) "Rule 16b-3" means Rule 16b-3, as from time to time in effect and
applicable to the Plan and Participants, promulgated by the Securities and
Exchange Commission under Section 16 of the Exchange Act.

      (i) "Share" means a share of common stock, $.01 par value, of the Company
and such other securities as may be substituted for such Share or such other
securities pursuant to Section 8.

      3. SHARES AVAILABLE UNDER THE PLAN. Subject to adjustment as provided in
Section 8, the total number of Shares reserved and available for issuance under
the Plan is 250,000. Such Shares may be authorized but unissued Shares, treasury
Shares, or Shares acquired in the market for the account of the Participant. For
purposes of the Plan, Shares that may be purchased upon exercise of an Option or
delivered in settlement of Deferred Shares will not be considered to be
available after such Option has been granted or Deferred Share credited, except
for purposes of issuance in connection with such Option or Deferred Share;
PROVIDED, HOWEVER, that, if an Option expires for any reason without having been
exercised in full, the Shares subject to the unexercised portion of such Option
will again be available for issuance under the Plan.

      4. ADMINISTRATION OF THE PLAN. The Plan will be administered by the Board
of Directors of the Company; PROVIDED, HOWEVER, that any action by the Board
relating to the Plan will be taken only if, in addition to any other required
vote, such action is approved by the affirmative vote of a majority of the
directors.

      5. ELIGIBILITY. Each director of the Company who, on any date on which an
Option is to be granted under Section 6 or on which fees are to be paid which
could be received in the form of Shares or deferred in the form of Deferred
Shares under Section 7, is not an employee of the Company or any subsidiary of
the Company will be eligible, at such date, to be granted an Option under
Section 6 or receive fees in the form of Shares or defer fees in the form of
Deferred Shares under Section 7. No person other than those specified in this
Section 5 will be eligible to participate in the Plan.

      6. OPTIONS. An Option to purchase 10,000 Shares, subject to adjustment as
provided in Section 8, will be automatically granted, (i) at the commencement of
the Initial Public

                                    -2-

Offering, to each person who is serving as a director of the Company at that
time or who becomes a director of the Company at that time and who is eligible
under Section 5 at that time, and thereafter (ii) at the effective date of
initial election to the Board of Directors, to each person so elected who is
eligible under Section 5 at that date. In addition, an Option to purchase 5,000
Shares, subject to adjustment as provided in Section 8, will be automatically
granted, at the close of business of each annual meeting of stockholders of the
Company, to each member of the Board of Directors who is eligible under Section
5 at the close of business of such annual meeting. Notwithstanding the
foregoing, any person who was automatically granted an Option to purchase 10,000
Shares at the effective date of initial election to the Board of Directors shall
not be automatically granted an Option to purchase 5,000 shares at the first
annual meeting of stockholders following such initial election if such annual
meeting takes place within three months of the effective date of such person's
initial election to the Board of Directors.

      (a) EXERCISE PRICE. The exercise price per Share purchasable upon exercise
of an Option will be equal to 100% of the Fair Market Value of a Share on the
date of grant of the Option.

      (b) OPTION EXPIRATION. A Participant's Option will expire at the earlier
of (i) 10 years after the date of grant or (ii) one year after the date the
Participant ceases to serve as a director of the Company for any reason.

      (c) EXERCISABILITY. Each Option may be exercised commencing immediately
upon its grant.

      (d) METHOD OF EXERCISE. A Participant may exercise an Option, in whole or
in part, at such time as it is exercisable and prior to its expiration, by
giving written notice of exercise to the Secretary of the Company, specifying
the Option to be exercised and the number of Shares to be purchased, and paying
in full the exercise price in cash (including by check) or by surrender of
Shares already owned by the Participant having a Fair Market Value at the time
of exercise equal to the exercise price, or by a combination of cash and Shares.

      7. RECEIPT OF SHARES OR DEFERRED SHARES IN LIEU OF FEES. Each director of
the Company may elect to be paid fees, in his or her capacity as a director
(including annual retainer fees for service on the Board, fees for service on a
Board committee, fees for service as chairman of a Board committee, and any
other fees paid to directors) in the form of Shares or Deferred Shares in lieu
of cash payment of such fees, if such director is eligible to do so under
Section 5 at the date any such fee is otherwise payable. If so elected, payment
of fees in the form of Shares or Deferred Shares shall be made in accordance
with this Section 7.

      (a) ELECTIONS. Each director who elects to be paid fees for a given
calendar year in the form of Shares or to defer such payment of fees in the form
of Deferred Shares for such

                                    -3-

year must file an irrevocable written election with the Secretary of the Company
no later than December 31 of the year preceding such calendar year; PROVIDED,
HOWEVER, that any newly elected or appointed director may file an election for
any year not later than 30 days after the date such person first became a
director, and a director may file an election for the year in which the Plan
became effective not later than 30 days after the date of effectiveness. An
election by a director shall be deemed to be continuing and therefore applicable
to subsequent Plan years unless the director revokes or changes such election by
filing a new election form by the due date for such form specified in this
Section 7(a). The election must specify the following:

            (i) A percentage of fees to be received in the form of Shares or
      deferred in the form of Deferred Shares under the Plan; and

            (ii) In the case of a deferral, the period or periods during which
      settlement of Deferred Shares will be deferred (subject to such
      limitations as may be specified by counsel to the Company).

      Certain elections may not result in receipt of Shares or deferral of fees
as Deferred Shares.

      (b) PAYMENT OF FEES IN THE FORM OF SHARES. At any date on which fees are
payable to a Participant who has elected to receive such fees in the form of
Shares, the Company will issue to such Participant, or to a designated third
party for the account of such Participant, a number of Shares having an
aggregate Fair Market Value at that date equal to the fees, or as nearly as
possible equal to the fees (but in no event greater than the fees), that would
have been payable at such date but for the Participant's election to receive
Shares in lieu thereof. If the Shares are to be credited to an account
maintained by the Participant and to the extent reasonably practicable without
requiring the actual issuance of fractional Shares, the Company shall cause
fractional Shares to be credited to the Participant's account. If fractional
Shares are not so credited, any part of the Participant's fees not paid in the
form of whole Shares will be payable in cash to the Participant (either paid
separately or included in a subsequent payment of fees, including a subsequent
payment of fees subject to an election under this Section 7).

      (c) DEFERRAL OF FEES IN THE FORM OF DEFERRED SHARES. The Company will
establish a deferral account for each Participant who elects to defer fees in
the form of Deferred Shares under this Section 7. At any date on which fees are
payable to a Participant who has elected to defer fees in the form of Deferred
Shares, the Company will credit such Participant's deferral account with a
number of Deferred Shares equal to the number of Shares having an aggregate Fair
Market Value at that date equal to the fees that otherwise would have been
payable at such date but for the Participant's election to defer receipt of such
fees in the form of Deferred Shares. The amount of Deferred Shares so credited
shall include fractional Shares calculated to at least three decimal places.

                                    -4-

      (d) CREDITING OF DIVIDEND EQUIVALENTS. Whenever dividends are paid or
distributions made with respect to Shares, a Participant to whom Deferred Shares
are then credited in a deferral account shall be entitled to receive, as
dividend equivalents, an amount equal in value to the amount of the dividend
paid or property distributed on a single Share multiplied by the number of
Deferred Shares (including any fractional Share) credited to his or her deferral
account as of the record date for such dividend or distribution. Such dividend
equivalents shall be credited to the Participant's deferral account as a number
of Deferred Shares determined by dividing the aggregate value of such dividend
equivalents by the Fair Market Value of a Share at the payment date of the
dividend or distribution.

      (e) SETTLEMENT OF DEFERRED SHARES. The Company will settle the
Participant's deferral account by delivering to the Participant (or his or her
beneficiary) a number of Shares equal to the number of whole Deferred Shares
then credited to his or her deferral account (or a specified portion in the
event of any partial settlement), together with cash in lieu of any fractional
Share remaining at a time that less than one whole Deferred Share is credited to
such deferral account. Such settlement shall be made within 30 days of the
Participant's resignation from Board of Directors of the Company.

      (f)   DELAYED EFFECTIVENESS OF ELECTIONS IN ORDER TO COMPLY WITH
RULE 16B-3. Other provisions of this Section 7 notwithstanding, if any payment
of fees in the form of Shares or deferral of fees in the form of Deferred Shares
would occur (i) less than six months after the Participant filed the election
which would result in such payment or deferral, (ii) at a time when the
Company's employee benefit plans are being operated in conformity with Rule
16b-3 as in effect on and after May 1, 1991, and (iii) at a time that Rule 16b-3
imposes a requirement that participant-directed transactions occur more than six
months after the participant's making of an irrevocable election in order for
such transactions to be exempt from Section 16(b) liability, then such fees
instead shall be paid in cash on a non-deferred basis.

      (g) NONFORFEITABILITY. The interest of each Participant in any fees paid
in the form of Shares or Deferred Shares (and any deferral account relating
thereto) at all times will be nonforfeitable.

8.    ADJUSTMENT PROVISIONS.

      (a) CORPORATE TRANSACTIONS AND EVENTS. In the event any dividend or other
distribution (whether in the form of cash, Shares or other property),
recapitalization, forward or reverse split, reorganization, merger,
consolidation, spin-off, combination, repurchase, exchange of Shares or other
securities of the Company, extraordinary dividend (whether in the form of cash,
Shares, or other property), liquidation, dissolution, or other similar corporate
transaction or event affects the Shares such that an adjustment is appropriate
in order to prevent dilution or enlargement

                                    -5-

of each Participant's rights under the Plan, then an adjustment shall be made,
in a manner that is proportionate to the change to the Shares and otherwise
equitable, in (i) the number and kind of Shares remaining reserved and available
for issuance under Section 3, (ii) the number and kind of Shares to be subject
to each automatic grant of an Option under Section 6, (iii) the number and kind
of Shares issuable upon exercise of outstanding Options, and/or the exercise
price per Share thereof (provided that no fractional Shares will be issued upon
exercise of any Option), (iv) the kind of Shares to be issued in lieu of fees
under Section 7, and (v) the number and kind of Shares to be issued upon
settlement of Deferred Shares under Section 7. In addition, the Board of
Directors is authorized to make such adjustments in recognition of unusual or
non-recurring events (including, without limitation, events described in the
preceding sentence) affecting the Company or any subsidiary or the financial
statements of the Company or any subsidiary, or in response to changes in
applicable laws, regulations or accounting principles. The foregoing
notwithstanding, no adjustment may be made hereunder except as will be necessary
to maintain the proportionate interest of the Participant under the Plan and to
preserve, without exceeding, the value of outstanding Options and potential
grants of Options and the value of outstanding Deferred Shares.

      (b) INSUFFICIENT NUMBER OF SHARES. If at any date an insufficient number
of Shares are available under the Plan for the automatic grant of Options or the
receipt of fees in the form of Shares or deferral of fees in the form of
Deferred Shares at that date, Options will first be automatically granted
proportionately to each eligible director, to the extent Shares are then
available (provided that no fractional Shares will be issued upon exercise of
any Option) and otherwise as provided under Section 6, and then, if any Shares
remain available, fees shall be paid in the form of Shares or deferred in the
form of Deferred Shares proportionately among directors then eligible to
participate to the extent Shares are then available and otherwise as provided
under Section 7.

      9. CHANGES TO THE PLAN. The Board of Directors may amend, alter, suspend,
discontinue, or terminate the Plan or authority to grant Options or pay fees in
the form of Shares or Deferred Shares under the Plan without the consent of
stockholders or Participants, except that any amendment or alteration will be
subject to the approval of the Company's stockholders at or before the next
annual meeting of stockholders for which the record date is after the date of
such Board action if such stockholder approval is required by any federal or
state law or regulation or the rules of any stock exchange or automated
quotation system as then in effect, and the Board may otherwise determine to
submit other such amendments or alterations to stockholders for approval;
PROVIDED, HOWEVER, that, without the consent of an affected Participant, no such
action may materially impair the rights of such Participant with respect to any
previously granted Option or any previous payment of fees in the form of Shares
or Deferred Shares.

                                    -6-

      10.   GENERAL PROVISIONS.

      (a) AGREEMENTS. Options, Deferred Shares, and any other right or
obligation under the Plan may be evidenced by agreements or other documents
executed by the Company and the Participant incorporating the terms and
conditions set forth in the Plan, together with such other terms and conditions
not inconsistent with the Plan, as the Board of Directors may from time to time
approve.

      (b) COMPLIANCE WITH LAWS AND OBLIGATIONS. The Company will not be
obligated to issue or deliver Shares in connection with any Option, in payment
of any directors' fees, or in settlement of Deferred Shares in a transaction
subject to the registration requirements of the Securities Act of 1933, as
amended, or any other federal or state securities law, any requirement under any
listing agreement between the Company and any stock exchange or automated
quotation system, or any other law, regulation, or contractual obligation of the
Company, until the Company is satisfied that such laws, regulations, and other
obligations of the Company have been complied with in full. Certificates
representing Shares issued under the Plan will be subject to such stop-transfer
orders and other restrictions as may be applicable under such laws, regulations,
and other obligations of the Company, including any requirement that a legend or
legends be placed thereon.

      (c) LIMITATIONS ON TRANSFERABILITY. Options, Deferred Shares, and any
other right under the Plan will not be transferable by a Participant except by
will or the laws of descent and distribution (or to a designated beneficiary in
the event of a Participant's death), and will be exercisable during the lifetime
of the Participant only by such Participant or his or her guardian or legal
representative; PROVIDED, HOWEVER, that Options and Deferred Shares (and rights
relating thereto) may be transferred to one or more trusts or other
beneficiaries during the lifetime of the Participant for purposes of the
Participant's estate planning or at the Participant's death, and such
transferees may exercise rights thereunder in accordance with the terms thereof,
but only if and to the extent then permitted under Rule 16b-3 and consistent
with the registration of the offer and sale of Shares related thereto on Form
S-8, Form S-3, or such other registration form of the Securities and Exchange
Commission as may then be filed and effective with respect to the Plan. The
Company may rely upon the beneficiary designation last filed in accordance with
this Section 10(c). Options, Deferred Shares, and other rights under the Plan
may not be pledged, mortgaged, hypothecated, or otherwise encumbered, and shall
not be subject to the claims of creditors of any Participant.

      (d) NO RIGHT TO CONTINUE AS A DIRECTOR. Nothing contained in the Plan or
any agreement hereunder will confer upon any Participant any right to continue
to serve as a director of the Company.

                                    -7-

      (e) NO STOCKHOLDER RIGHTS CONFERRED. Nothing contained in the Plan or any
agreement hereunder will confer upon any Participant (or any person or entity
claiming rights by or through a Participant) any rights of a stockholder of the
Company unless and until Shares are in fact issued to such Participant (or
person) or, in the case an Option, such Option is validly exercised in
accordance with Section 6.

      (f) NONEXCLUSIVITY OF THE PLAN. Neither the adoption of the Plan by the
Board of Directors nor its submission to the stockholders of the Company for
approval shall be construed as creating any limitations on the power of the
Board to adopt such other compensatory arrangements for directors as it may deem
desirable.

      (g) GOVERNING LAW. The validity, construction, and effect of the Plan and
any agreement hereunder will be determined in accordance with the laws of the
State of Delaware, without giving effect to principles of conflicts of laws, and
applicable federal law.

11. STOCKHOLDER APPROVAL, EFFECTIVE DATE, AND PLAN TERMINATION. The Plan will be
effective as of the date of its adoption by the Board, subject to stockholder
approval prior to the commencement of the Initial Public Offering, and, unless
earlier terminated by action of the Board of Directors, shall terminate at such
time as no Shares remain available for issuance under the Plan and the Company
and Participants have no further rights or obligations under the Plan.
