FORWARD-LOOKING STATEMENTS This report contains forward-looking statements regarding the business and industry of Comfort Systems USA, Inc., a Delaware corporation ("Comfort Systems" and collectively with its subsidiaries, the "Company"), within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are based on the current plans and expectations of the Company and involve risks and uncertainties that could cause actual future activities and results of operations to be materially different from those set forth in the forward-looking statements. Important factors that could cause actual results to differ are discussed under "Management's Discussion and Analysis of Financial Condition and Results of Operations - Factors Which May Affect Future Results." PART I ITEM 1. BUSINESS Comfort Systems is a leading national provider of comprehensive heating, ventilation and air conditioning ("HVAC") installation, maintenance, repair and replacement services. Founded in December 1996, the Company is consolidating the fragmented commercial and industrial HVAC markets, and performs most of its services within office buildings, retail centers, apartment complexes, hotels, manufacturing plants and government facilities. In addition to standard HVAC services, the Company also provides specialized applications such as process cooling, control systems, electronic monitoring and process piping. Certain locations also perform related services such as electrical and plumbing. Approximately 94% of the Company's pro forma combined 1997 revenues were derived from commercial and industrial customers. On June 27, 1997, Comfort Systems completed the initial public offering (the "Offering") of its common stock (the "Common Stock") and simultaneously acquired in separate concurrent transactions twelve companies (collectively referred to as the "Founding Companies") engaged in providing HVAC services. The Founding Companies had operations in ten states and pro forma combined revenues in 1996 of $167.5 million. Subsequent to June 30, 1997, and through December 31, 1997, the Company acquired 27 HVAC and related businesses. These companies added approximately $190 million of annualized revenues to Comfort Systems and added operating locations in an additional 10 states, (which includes Puerto Rico). These acquisitions included six "tuck-in" operations which were combined with existing Comfort Systems locations in 1997. In addition, during the first two months of 1998, the Company acquired five HVAC businesses with aggregate 1997 annual revenues of approximately $109 million. 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 HVAC industry as a whole 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, and older HVAC systems result in significantly higher energy costs than do modern systems. 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 air quality and the effectiveness of the HVAC system. These factors are causing facility owners to examine replacement of older systems. 1 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, (iii) growing attention to indoor air quality resulting in the consideration of higher indoor air quality standards, and (iv) 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. The Company believes that these factors also mitigate the effect on the HVAC industry of the cyclicality inherent in the traditional construction industry. The HVAC industry is subject to seasonal variations. Specifically, the demand for new installations and for replacement is generally lower during the winter months due to reduced construction activity 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 calendar quarters due to increased construction activity and 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 calendar 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. 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 relatively 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 to excel in the HVAC 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 the specific needs of the building owner. Costs and other project terms are normally negotiated between the building owner or their representative and the HVAC firm. Firms which specialize in "design and build" projects generally have specially-trained HVAC engineers, CAD/CAM design systems and 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 systems 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 by a third party and resulting bid process often take months to complete. Furthermore, in "plan and spec" projects, the HVAC firm is not responsible for project design and any changes must be approved by several parties, thereby increasing overall project time and cost. Approximately 55% of the Company's pro forma combined 1997 revenues related to installation services and the majority of the revenues from installation projects were performed on a "design and build" basis. MAINTENANCE, REPAIR AND REPLACEMENT SEGMENT. This segment includes the maintenance, repair, replacement, reconfiguration and monitoring of previously installed HVAC systems and controls. The aging of the installed base of HVAC systems and the increasing demand for more efficient, sophisticated and complex systems and controls have fueled growth in this segment. 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 2 service providers. In addition, increasing restrictions are being placed on the use of certain types of refrigerants used in HVAC systems, which, along with indoor air quality concerns, may increase demand for the reconfiguration and replacement of existing HVAC systems. State-of-the-art control and monitoring systems feature electronic sensors and microprocessors. These systems require specialized training to install, maintain and repair and the typical building engineer has not received this training. 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. Approximately 45% of the Company's pro forma combined 1997 revenues related to maintenance, repair and replacement services. STRATEGY The Company has implemented an aggressive operating strategy that emphasizes continued internal growth and expansion through acquisitions. OPERATING STRATEGY. The key elements of the Company's operating strategy are: FOCUS ON COMMERCIAL AND INDUSTRIAL MARKETS. The Company focuses principally on the commercial and industrial markets with particular emphasis on the "design and build" installation segment 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, reduced weather exposure as compared to residential markets, attractive margins and potential for long-term relationships with building owners, property managers, general contractors and architects. OPERATE ON A DECENTRALIZED BASIS. The Company manages its subsidiaries on a decentralized basis, with local management maintaining responsibility for day-to-day operations, profitability and growth. While it maintains strong operating and financial controls, the Company believes that its decentralized operating structure allows local management of each Company to capitalize on their knowledge of local and regional markets and on customer relationships possessed by each acquired company. ACHIEVE OPERATING EFFICIENCIES. The Company believes there are opportunities to achieve operating efficiencies and cost savings through purchasing economies and the adoption of "best practices" operating programs. The Company seeks to use its growing purchasing power to gain volume discounts on products and services such as HVAC components, raw materials, service vehicles, advertising, bonding, insurance and benefits. Moreover, the Company reviews 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 attracts and retains 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) attractive benefits packages. INTERNAL GROWTH. A key component of the Company's strategy is to continue the internal growth at the Company's subsidiaries. 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 continue to expand the services it offers in its markets by leveraging the specialized technical and marketing strengths of individual acquired companies. The Company also believes its growing geographical coverage will enable it to serve existing customers' needs in new regions that may have been beyond the service area of the Company's operations that originated the existing customer relationship. In addition, a number of acquired companies currently focus primarily on installation and, 3 therefore, have only limited maintenance, repair and replacement operations. The Company believes there are significant opportunities for these acquired companies to provide maintenance, repair and replacement services, particularly by offering these services to customers for whom those companies have already designed and built systems. Several of the acquired companies have specific expertise in HVAC control and monitoring systems, process cooling, replacement and other service strengths. This expertise has been and will be increasingly shared within the Company's family of HVAC businesses. ESTABLISH REGIONAL AND NATIONAL MARKET COVERAGE. The Company believes that significant demand exists from large regional and 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 acquired 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 it can expand these existing relationships as it develops a nationwide network to provide these customers with a single source for all of their HVAC needs to promote consistent service, improve control and reduce cost. ACQUISITIONS. Based on available industry data, the Company believes the HVAC industry is highly fragmented, with small, owner-operated businesses with limited capital resources, which outnumber larger enterprises. The key elements of the Company's acquisition strategy are: ENTER NEW GEOGRAPHIC MARKETS. In new markets, Comfort Systems targets one or more leading local or regional companies providing HVAC services. The acquisition target has the customer base, technical skills and infrastructure necessary to be a core business into which other HVAC and/or complimentary service operations can be consolidated or "tucked-in." The Company chooses 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 seeks to acquire other well-established HVAC businesses to expand its market penetration and range of services offered. The Company also pursues "tuck-in" acquisitions of smaller companies, whose operations can be integrated into an existing operation to leverage the existing infrastructure of the previously acquired company. ACQUIRE COMPLIMENTARY BUSINESSES. The Company acquires companies providing complimentary services to the same customer base, such as commercial and industrial control systems, process piping, plumbing and electrical services. This enables 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 is regarded by acquisition candidates as an attractive acquirer because of; (i) the Company's strategy to become a national, comprehensive and professionally managed HVAC service provider focused on commercial and industrial markets; (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. As consideration for acquisitions, the Company will 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 include historical operating results, future prospects of the acquiree and the ability of a business to complement the services offered by the Company. 4 OPERATIONS SERVICES PROVIDED The Company provides a wide range of installation, maintenance, repair and replacement services for HVAC and related systems in commercial, industrial and, to a lesser extent, residential properties. Daily operations are managed on a local basis by the management team at each acquired company. In addition to senior management, acquired companies' personnel generally include design engineers, sales personnel, customer service personnel, installation service technicians, sheet metal and prefabrication technicians, estimators and administrative personnel. The Company manages the acquired companies on a decentralized basis, with local management maintaining responsibility for day-to-day operating decisions. The Company is in the process of centralizing certain administrative functions to enable the management of each acquired company to focus on pursuing new business opportunities and improving operating efficiencies. Administrative functions which the Company is centralizing include company-wide training and safety programs, certain accounting functions, risk management programs, cash management programs, purchasing programs and employee benefits. INSTALLATION SEGMENT. The Company's installation business comprised approximately 55% of the Company's 1997 pro forma combined revenues. This segment consists of the design, engineering, integration, installation and start-up of HVAC and related 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 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. The drawings are prepared in a format appropriate for submission to local building inspectors. The 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 practice enables the Company to limit the amount of fieldwork required for installation, reduce the labor associated with the installation process and, therefore, 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 and, in most cases, with a 10% retainage held back until completion and successful start-up of the HVAC system. 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 bid on more of these projects when "design and build" projects are in lower demand and when additional on-the-job training is needed for apprentice or less-experienced technicians. 5 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 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. This monitoring can be performed on-site or remotely through a PC-based communications system. The monitoring system will communicate an exception 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 material, support utilities and finished products. MAINTENANCE, REPAIR AND REPLACEMENT SEGMENT. The Company's maintenance, repair and replacement segment comprised approximately 45% of the Company's 1997 pro forma combined revenues, and includes the maintenance, repair, replacement, reconfiguration and monitoring of HVAC systems and industrial process piping. Approximately two-thirds of the Company's maintenance, repair and replacement segment revenues were 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 communication technology to process orders, arrange service calls, communicate with customers, dispatch technicians and invoice customers. Service technicians work from service vehicles 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. 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. 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 extend to a month or more. 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 does not have any significant contracts for the supply of raw materials or components. 6 SALES AND MARKETING The Company has a diverse customer base, with no single customer accounting for more than 6% of the Company's historical consolidated 1997 revenues or 4% of pro forma combined 1997 revenues. Management and a dedicated sales force at the acquired companies have been responsible for developing and maintaining successful long-term relationships with key customers. Customers of the acquired 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 their customers. The Company also intends to capitalize on cross-marketing and business development opportunities that management believes are available to the Company as a national provider of comprehensive commercial and industrial HVAC and related services. Management believes that it will be able to leverage the diverse technical and marketing strengths of individual acquired companies to expand the services offered in other local markets. Eventually, the Company intends to offer comprehensive services from many of its regional locations. EMPLOYEES As of December 31, 1997, the Company had 3,119 employees, including 198 management personnel, 2,430 engineers and service and installation technicians, 130 sales personnel and 361 administrative personnel. As it executes its internal growth and acquisition strategies, the Company expects the number of employees to increase. Certain of the Company's subsidiaries have collective bargaining agreements that cover, in the aggregate, approximately 370 employees. The Company has not experienced any strikes or work stoppages and believes its relations with employees covered by collective bargaining agreements are good. RECRUITING, TRAINING AND SAFETY The Company's continued 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. Additionally, Comfort Systems provides on-the-job training, apprenticeship programs, attractive benefit packages, steady employment and opportunities for advancement. The Company intends to establish "best practices" safety programs throughout its operations to ensure that all technicians comply with safety standards established by the Company 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. 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 which will provide additional guidance in safety related matters such as proper lifting techniques and eye safety in an effort to reduce the number of preventable accidents. 7 RISK MANAGEMENT, INSURANCE AND LITIGATION The primary risks in the Company's operations are bodily injury, property damage and injured workers' compensation. The Company has obtained and intends to 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 Company is subject to certain claims and lawsuits arising in the normal course of business and maintains various insurance coverages to minimize financial risk associated with these claims. The Company has provided accruals for probable losses and legal fees associated with certain of these actions in the accompanying consolidated financial statements. In the opinion of management, uninsured losses, if any, resulting from the ultimate resolution of these matters will not have a material effect on the Company's financial position or results of operations. The Company's subsidiaries typically warrant labor for the first year after installation on new air conditioning and heating systems and pass to the customer warranties on equipment purchased from manufacturers. The Company's subsidiaries generally warrant labor for 30 days after servicing of existing air conditioning and heating systems. The Company does not expect warranty claims to have a material adverse effect on its financial position 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, however, a few public companies focused on providing HVAC services in some of the same service lines provided by the Company. In addition, there are other 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. 8 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 of 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 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 utilize CFCs to systems using alternative refrigerants is expected to increase. The Company is not aware of any material environmental liabilities associated with its properties. EXECUTIVE OFFICERS The Company has five executive officers. Fred M.

HIGH LOW ---- --- June 27-30, 1997............................. $ 16.125 $ 13.00 Third Quarter, 1997.......................... $ 21.5625 $ 15.50 Fourth Quarter, 1997......................... $ 20.0625 $ 15.00 As of March 24, 1998, there were approximately 278 stockholders of record of the Company's Common Stock, and the last reported sale price on that date was $20.625 per share. The Company has never declared or paid a dividend on its Common Stock. The Company expects to retain all future earnings in order to finance its acquisition program and, consequently, does not intend to declare any dividend on the Common Stock for the foreseeable future. In addition, the Company's revolving credit agreement restricts the ability of the Company to pay dividends without the lender's consent. No market exists for the Company's Restricted Voting Common Stock, which converts to Common Stock upon transfer. SALE OF UNREGISTERED SECURITIES On January 6, 1997, Comfort Systems issued and sold shares of Common Stock to the following parties in the amounts and for the consideration indicated.

Each of these transactions was complete without registration under the Securities Act in reliance on the exemption provided by Section 4(2), no public offering being involved. ITEM 6. SELECTED FINANCIAL DATA Comfort Systems acquired the twelve Founding Companies in connection with the Offering on June 27, 1997. During the remainder of 1997, the Company completed 27 acquisitions, 14 of which were accounted for as pooling-of-interests (the "Pooled Companies") and 13 of which were accounted for as purchases (the "Purchased Companies"). The following selected historical financial data has been derived from the audited financial statements of the Company for each of the three years ended December 31, 1995, 1996, and 1997, and retroactively reflects the Pooled Companies as appropriate. The remaining selected historical financial data of the Company has been derived from unaudited financial statements of the Company. These unaudited financial statements have been prepared on the same basis as the audited financial statements of the Company, and in the opinion of the Company, reflect all adjustments necessary for a fair presentation of that historical information. The historical financial statement data reflects the acquisitions of the Founding Companies and Purchased Companies as of their respective acquisition dates and reflects eight of the Pooled Companies (the "Restated Companies") for all periods presented. Certain of the Pooled Companies are considered immaterial poolings based upon the relative significance of their individual operations and have not been restated for all periods presented. The selected historical financial data below should be read in conjunction with the historical financial statements and related notes.

12 ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS INTRODUCTION The following discussion should be read in conjunction with the consolidated historical financial statements of the Company and related notes thereto. This discussion contains forward-looking statements regarding the business and industry of Comfort Systems within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are based on the current plans and expectations of the Company and involve risks and uncertanties that could cause actual future activities and results of operations to be materially different from those set forth in the forward-looking statements. Important factors that could cause actual results to differ include, among others, risks associated with the difficulty of integrating newly acquired companies while maintaining their financial performance, seasonal or cyclical variation in demand for the Company's products and services, the ability to obtain acquisition financing, increasing competition for acquisition targets as new companies enter the market for HVAC consolidation, labor availability, and the continued issuance of new shares and the resulting overhang of saleable stock and other risks detailed in the Company's continuing reports filed with the Securities and Exchange Commission. Comfort Systems was founded in December 1996 to become a leading national provider of HVAC services, focusing primarily on commercial and industrial markets. On June 27, 1997, Comfort Systems completed the Offering of its Common Stock and simultaneously acquired the twelve Founding Companies, which are engaged in providing HVAC services. The closing of the acquisitions of the Founding Companies and the Offering occurred on July 2, 1997. Subsequent to June 30, 1997, and through December 31, 1997, the Company acquired 27 additional HVAC businesses. Of these additional acquisitions, fourteen acquisitions were accounted for as poolings-of-interests and are referred to herein as the Pooled Companies, and the remaining thirteen acquisitions were accounted for as purchases and are referred to herein as the Purchased Companies. The historical financial statements of the Company have been retroactively restated to give effect to the operations of the Restated Companies. Certain of the Pooled Companies are considered immaterial poolings and have not been restated for all periods presented based upon the relative significance of their individual operations as discussed in Item 6. Pro forma and historical results are not necessarily indicative of future results of the Company because, among other things, the acquired companies were not under common control or management prior to their acquisition. The results of the Company have historically been subject to seasonal fluctuations. These pro forma combined and historical statements of operations should be read in conjunction with the consolidated financial statements and related notes of Comfort Systems, filed herewith, and the additional information and the respective financial statements and related notes of Comfort Systems and the Founding Companies included in the Company's Registration Statement on Form S-1 (File No. 333-24021) (the "Registration Statement"), as amended, filed with the Securities and Exchange Commission in connection with the Offering. The timing and magnitude of acquisitions, assimilation costs and the seasonal nature of the HVAC industry may materially affect operating results. Accordingly, the operating results for any period are not necessarily indicative of the results that may be achieved for any subsequent period. PRO FORMA The following pro forma information is presented supplementally to reflect the pro forma results of operations as if the acquisition of the Founding Companies occurred on January 1 of the respective years, as presented in the Registration Statement. Therefore, the accompanying unaudited pro forma combined statements of operations and the related management's discussion and analysis of the Company for the years ended December 31, 1997 and 1996, respectively, include the combined operations of the Restated 13 Companies and the Founding Companies from January 1, 1996, and the Purchased Companies from the dates of their acquisition. Certain of the Pooled Companies are considered immaterial poolings and have not been restated for all periods presented. The Founding Companies, Pooled Companies and Purchased Companies were managed prior to their acquisitions as independent private companies. Therefore, historical selling, general, and administrative expenses for the periods presented in the consolidated financial statements of the Company reflect compensation and related benefits the owners of those businesses received prior to acquisition. Historical selling, general and administrative expenses also include the non-recurring non-cash compensation charge of $11.6 million recorded by Comfort Systems in the first quarter of 1997 related to Common Stock issued to management of and consultants to the Company. The following pro forma combined results of operations have been presented for the purpose of reflecting net income as if the merger of the Founding Companies and the acquisition of the Restated Companies occurred January 1, 1996 and 1997. The pro forma adjustments reflect: (a) certain reductions in salaries and benefits to the former owners ("the Compensation Differential") of the Founding and Purchased Companies which they agreed would take effect as of the date of the acquisitions, (b) pro forma compensation expense of $430,000 for the six months ended June 30, 1997, to reflect the ongoing salaries received by corporate management as though those salaries were being paid prior to the Offering, (c) interest expense on borrowings of $11.0 million that would have been necessary to fund the S Corporation Distributions if they had occurred at the beginning of each period presented, (d) the elimination of the $11.6 million non-recurring non-cash compensation charge referred to above, and (e) the reduction of the acquisition-related costs incurred in the acquisition of the Pooled Companies. In addition, an incremental tax provision has been recorded as if all applicable Purchased and Founding Companies, and Pooled Companies which were C Corporations had been subject to federal and state income taxes. RESULTS OF OPERATIONS - PRO FORMA COMBINED (UNAUDITED)

1997 COMPARED TO 1996 PRO FORMA REVENUES - Pro forma combined revenues increased 23% to $324.6 million for the year ended December 31, 1997. Revenues of $16.7 million for the Purchased Companies acquired in 1997 are included in 1997. No results for these companies are included in 1996. Excluding these amounts, revenues increased 16.7% from 1996 to 1997. This increase was primarily attributable to significant "design and build" projects in the Company's Phoenix operations for a new medical center and a semiconductor fabrication facility, broad growth in commercial and industrial "design and build" activities in Tennessee operations, increased general demand for the Company's services in the Grand Rapids, Michigan market, greater demand for specialized multi-unit installation services in Texas and the Northeast, and increased demand for the Company's commercial service capabilities in the Cincinnati market. 14 PRO FORMA GROSS PROFIT - Pro forma combined gross profit increased 25.4% to $90.3 million for the year ended December 31,1997, primarily due to increased revenue volume. Gross profit from certain Purchased Companies, which are not reported in 1996 results, accounted for 4.4% of the pro forma gross profit in the current year. Pro forma combined gross profit as a percentage of revenues increased from 27.3% to 27.8% in 1997. This increase in gross profit margin was primarily attributable to an overall improvement from the Companies' operations in Mobile, Alabama, associated with its specialized "design and build" HVAC installation capabilities, and the somewhat higher gross margins resulting from the installation and service of HVAC controls-based energy management systems at two locations. These increases in gross profit margin were slightly offset by certain lower margin "design and build" installation projects, which were accepted as a strategic enhancement to the Company's portfolio of "design and build" projects. PRO FORMA SELLING, GENERAL AND ADMINISTRATION EXPENSES (SG&A) - Pro forma combined SG&A expenses, excluding goodwill amortization and non-recurring acquisition related costs, increased $14.2 million or 34.1% to $56.0 million for the year ended December 31,1997, compared to the prior year. Approximately $2.5 million of this increase is attributable to the Purchased Companies, which are not included in 1996 results. The Company's establishment as a public company in 1997 resulted in $2.2 million of corporate office and management expenses in 1997, whereas no such corporate expenses are reflected in 1996 as the Company was not yet public. The remaining increases in SG&A were due principally to additions of personnel and infrastructure to support growth in revenues. PRO FORMA OTHER INCOME (EXPENSE) - Pro forma net other expense decreased due to the increase in interest income of $0.7 million resulting from the investment of temporary excess cash following the Company's Offering of Common Stock in June 1997. HISTORICAL The following historical consolidated financial information represents the operations of the Restated Companies for all periods presented and the Founding Companies and Purchased Companies from their respective date of acquisitions. Certain of the Pooled Companies are considered immaterial poolings and have not been restated for all periods presented. The following historical financial information for 1997 includes the non-recurring non-cash compensation charge of $11.6 million recorded by Comfort Systems in the first quarter of 1997, non-recurring acquisition-related costs and reflects normal recurring corporate costs of Comfort Systems subsequent to the initial public offering. This compensation charge is not deductible for federal and state income taxes. This historical consolidated information has been derived from the audited Consolidated Financial Statements of the Company. RESULTS OF OPERATIONS - HISTORICAL

15 1997 COMPARED TO 1996 REVENUES - Revenues increased $141.4 million, or 146.9%, over 1996, to $237.7 million for the year ended December 31, 1997. The acquisition of the Founding Companies as of July 2, 1997, and the acquisition of the Purchased Companies in the second half of 1997, accounted for 88.2% of the increase in revenues over the prior year. The remaining increase in revenues over the prior year is primarily attributable to increased demand for the Company's commercial service capabilities in the Cincinnati market. GROSS PROFIT - Gross profit increased $41.6 million, or 172.1%, over 1996, to $65.8 million for the year ended December 31, 1997. The acquisition of the Founding Companies and Purchased Companies accounted for 81.5% of the increase over the prior year. Gross profit as a percentage of revenues increased as a result of the Founding Companies' positive impact on the overall gross profit percentage in the second half of 1997 and an overall improvement from the Pooled Companies compared to the prior year. The Company's operations in Mobile, Alabama contributed the largest increase as a percentage of revenues among the Pooled Companies due to higher margins associated with its specialized "design and build" HVAC installation capabilities. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES - SG&A, excluding goodwill amortization, increased $40.3 million, or 211.0%, over 1996, to $59.4 million for 1997. Approximately one half of this increase is related to the acquisition of the Founding and Purchased Companies. Historical SG&A for 1997 includes the non-recurring, non-cash compensation charge of $11.6 million recorded by Comfort Systems in the first quarter of 1997 related to Common Stock issued to management of and consultants to the Company. The Company's establishment as a public company in 1997 resulted in $2.8 million of corporate office and management expenses in 1997 whereas no such corporate expenses are reflected in 1996 as the Company was not yet public. Of this amount, approximately $0.6 million was non-recurring acquisition costs related to the Pooled Companies. The remaining increase related to increases in personnel and infrastructure to support growth at certain of the Pooled Companies, and does not reflect the reduction in management compensation and benefits as a result of the mergers of these Pooled Companies with Comfort Systems. OTHER INCOME (EXPENSE) - Net other income increased to $0.1 million for the year ended December 31, 1997 due primarily to the increase in interest income of $0.7 million resulting from the investment of temporary excess cash following the Company's Offering of Common Stock in June. 1996 COMPARED TO 1995 REVENUES - Revenues increased $31.1 million, or 47.8%, to $96.3 million for the year ended December 31, 1996, compared to the year ended December 31, 1995. Certain Pooled Companies representing $12.3 million, or 39.5%, of the increase in revenue over 1995 are not included in 1995 results. The remaining increase in revenues over 1995 is primarily attributable to increased demand for the Company's commercial service capabilities in the Memphis market and commercial installation service capabilities in the Alabama market. GROSS PROFIT - Gross Profit increased $7.7 million, or 47.2%, to $24.2 million for the year ended December 31, 1996, compared to the year 16 ended December 31, 1995. Certain Pooled Companies representing $4.1 million, or 52.7%, of the increase over 1995 are not included in 1995 results. The remaining increase in gross profit was partially a result of increased demand for the Company's commercial service capabilities while maintaining gross profit margins in the Memphis market area and an improvement in gross profit margins in the Cincinnati operations. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES - SG&A, excluding goodwill amortization, increased $4.4 million, or 29.8%, to $19.1 million for the year ended December 31, 1996 compared to the year ended December 31, 1995. Certain Pooled Companies representing $2.3 million, or 52.6%, of the increase over 1995 are not included in the 1995 results. The majority of the remaining increase is due to an addition of personnel in the Cincinnati market area to capitalize on revenue growth opportunities. SG&A for the Pooled Companies in 1995 and 1996 reflects the compensation and related benefits those owners received from their respective businesses prior to the acquisition. LIQUIDITY AND CAPITAL RESOURCES - HISTORICAL For the year ended December 31, 1997, net cash used in operating activities was $1.7 million due to a decrease in accounts payable of $3.8 million and an increase in accounts receivables of $10.9 million. Accounts payable balances decreased from the date of acquisition at various locations as certain companies took advantage of the consolidated cash management system to receive cash discounts for early payments. Cash provided from operations for 1996 and 1995 was $3.3 million and $1.0 million, respectively, primarily as a result of net income for the periods. Cash used in investing activities was $57.5 million for the year ended 1997, primarily in connection with the acquisition of the Founding Companies and Purchased Companies for $54.1 million, net of cash acquired. Cash flows used in investing activities for 1996 and 1995 were $1.8 million and $0.7 million, respectively, primarily for additions to equipment. Cash provided by financing activities for the year ended December 31, 1997 was $67.7 million and was primarily attributable to the $79.9 million from the Offering which was partially offset by a net reduction in debt of $10.7 million in the second half of 1997. Net cash used in financing activities in 1996 was $0.8 million from a net reduction in outstanding debt. Net cash provided by financing activities in 1995 was $1.1 million due to the net increase in outstanding debt of $1.3 million. On June 27, 1997, Comfort Systems completed the offering of 6,100,000 shares of Common Stock to the public at $13.00 per share. The net proceeds to Comfort Systems from the Offering (after deducting underwriting commissions and offering expenses) were $68.8 million. Of this amount, $45.3 million was used to pay the cash portion of the purchase prices of the Founding Companies. In connection with the Offering, the Company granted its underwriters an option to sell an additional 915,000 shares at $13.00 per share. On July 9, the underwriters exercised this option. Net proceeds to the Company from this sale of shares were $11.1 million after deducting underwriting commissions. Subsequent to December 31, 1997, and through February 25, 1998, the Company completed acquisitions of five companies for approximately $15.1 million in cash, 2,002,894 shares of Common Stock and approximately $1.3 million in Convertible Subordinated Notes. The Company has filed a Current Report on Form 8-K related to one of these acquisitions. These acquisitions will be accounted for as purchase transactions. In July 1997, the Company entered into a credit agreement with Bank One, Texas, N.A. (the "Credit Facility"). The Credit Facility was amended and restated in September 1997 primarily to provide for additional banks to lend to the Company under the Credit Facility. The Credit Facility provides the Company with an unsecured revolving line of credit of $75 million. The Company has a choice of two interest rate options when borrowing under the Credit Facility. Under one option, the interest rate is determined based on the higher of the Federal Funds Rate plus one-half percentage point or the bank's prime rate. An additional margin of zero to one-quarter percentage point is then added to the higher of these two rates. The additional margin depends on the ratio of the Company's debt to earnings before interest, taxes, depreciation and amortization for the preceding twelve months ("EBITDA"). For purposes of this ratio, EBITDA may include the preceding twelve months' results for any companies acquired during the last year. Under the other interest rate option, borrowings bear interest based on designated short-term Eurodollar rates (which generally approximate the London Interbank Offered Rates or LIBOR, as published 17 in major financial media) plus one to two percentage points, again depending on the ratio of debt to EBITDA. In addition, commitment fees of 0.125% to 0.375% per annum, also depending on the ratio of debt to EBITDA, are payable on the unused portion of the line of credit. The Credit Facility prohibits the payment of dividends by the Company without lender's approval and requires the Company to comply with certain financial covenants. The Credit Facility expires on July 2, 2000, at which time, all amounts outstanding under the facility are due. As of December 31, 1997, $15.3 million was outstanding under the Credit Facility at an average interest rate of approximately 6.7% per annum for the second half of 1997. As of March 24, 1998, $43.8 million was outstanding under the Credit Facility. The Company is currently in discussion with existing and potential lenders to significantly increase the Credit Facility and extend its maturity to three years from the date of increase. The Company believes that all other terms and conditions of the Credit Facility will remain substantially unchanged if the Credit Facility is increased. The Company intends to pursue additional acquisition opportunities. The Company anticipates that available borrowings under its Credit Facility and 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. Should the Company accelerate or revise its acquisition program, the Company may need to seek additional financing through the public or private sale of equity or debt securities. There can be no assurance that the Company will secure such financing if and when it is needed, or that such financing will be available on terms that the Company deems acceptable. YEAR 2000 The Company is currently assessing the impact of "Year 2000" related issues on its operational and financial computer systems. The Company has not yet determined the operational impact, if any, which may result in the future. Therefore, the Company is unable to determine the potential impact, if any, on its results of operations or financial condition. SEASONALITY AND CYCLICALITY The HVAC industry is subject to seasonal variations. Specifically, the demand for new installation and replacement is generally lower during the winter months due to reduced construction activity 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 calendar quarters due to increased construction activity and 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 calendar 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. FACTORS WHICH MAY AFFECT FUTURE RESULTS The Company's future operating results are difficult to predict and may be affected by a number of factors, including the lack of a combined operating history and the difficulty of integrating acquired businesses, difficulties in implementing its acquisition strategy, seasonal and cyclical fluctuations in the demand for HVAC systems and the availability of acquisition financing. As a result of these and other factors, there can be no assurance that the Company will not experience material fluctuations in future operating results on a quarterly or annual basis. The Company's success depends in part on its ability to integrate the businesses that it acquires. The acquired businesses operated as separate, independent entities prior to their affiliation with the Company, and there can be no assurance that the Company will be able to integrate the operations of these businesses successfully or institute the necessary systems and procedures, including accounting and financial reporting 18 systems, to effectively manage the combined enterprise on a profitable basis. The pro forma combined historical financial results of the acquired businesses primarily cover periods when such businesses were not under common control or management and, therefore, may not be indicative of the Company's future financial or operating results. The Company has grown and intends to continue to grow significantly through the acquisition of additional HVAC and complementary businesses, but in the future it could face difficulties in implementing its acquisition strategy. The Company faces increasing competition for acquisition candidates, a fact that may limit the number of acquisition opportunities and may lead to higher acquisition prices. The HVAC industry is currently undergoing rapid consolidation on both a national and a regional level by the Company and by other companies that have acquisition objectives that are similar to the Company's objectives. 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. Acquisitions also involve a number of special risks, including failure of the acquired business to achieve expected results, diversion of management's attention and failure to retain key personnel of the acquired business. There are also risks associated with unanticipated events or liabilities resulting from the acquired businesses' operations prior to their acquisition. Any of these risks, or a combination of them, could have a material adverse effect on the Company's business, financial condition and results of operations. The timing, size and success of the Company's acquisition efforts depend in large part on the availability of financing. The Company intends to continue to finance future acquisitions by using shares of its Common Stock for 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, to maintain its acquisition program. One factor that may affect the Common Stock's market price in the future, and thus its usefulness as acquisition currency, is the dilutive effect of the continued issuance of shares in connection with acquisitions. The availability of such shares in the market when they become eligible for sale could affect the Company's stock valuation (i.e., upon the expiration of contractual restrictions or of specified holding periods for unregistered shares). If the Company fails to maintain its stock valuation, and 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 financing. Key elements of the Company's strategy are to both maintain and improve the profitability of the acquired businesses and to continue to expand the revenues of acquired businesses. The Company's level of success in this strategy, if any, will be affected by demand for new or replacement HVAC systems. In part, such demand will turn on factors outside the Company's control, such as the level of new construction or the potential for slower replacement based upon the overall level of activity in the economy. The HVAC industry is subject to both seasonal and cyclical variations, meaning that temperate weather and downturns in the domestic or a regional economy will negatively affect overall demand for the Company's services. 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. In addition, the Company depends on the senior management of the businesses it acquires to remain committed to the success of the business after its acquisition and through a transition period. Accordingly, the Company's ability to increase its productivity and profitability are also affected by its ability to employ, train and retain the skilled technicians necessary to meet the Company's service requirements, and to retain senior management in acquired businesses. 19 HVAC systems are also 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. The Company's failure to comply, or the costs of compliance, with such laws and regulations could adversely affect the Company's future results. Because of these and other factors, past financial performance should not necessarily be considered an indicator of future performance. Investors should not rely solely on historical trends to anticipate future results and should be aware that the trading price of the Company's Common Stock may be subject to wide fluctuations in response to quarter-to-quarter variations in operating results, general conditions in the HVAC industry, the increasing supply of tradable stock, changes in analysts' earnings estimates, and recommendations by analysts or other events. 20 ITEM 8.

The accompanying notes are an integral part of these consolidated financial statements. 26 COMFORT SYSTEMS USA, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 1997 1. BUSINESS AND ORGANIZATION: Comfort Systems USA, Inc., a Delaware corporation, ("Comfort Systems" and collectively with its subsidiaries, the "Company"), is a national provider of comprehensive heating, ventilation and air conditioning ("HVAC") installation, maintenance, repair and replacement services. Founded in December 1996, the Company is consolidating the fragmented commercial and industrial HVAC markets, executing most of its applications within office buildings, retail centers, apartment complexes, hotels, manufacturing plants and government facilities. In addition to standard HVAC services, the Company also provides specialized applications such as process cooling, control systems, electronic monitoring and process piping. Certain locations also perform related services such as electrical and plumbing. On June 27, 1997, Comfort Systems completed the initial public offering (the "Offering") of its common stock (the "Common Stock") and simultaneously acquired in separate concurrent transactions twelve companies (collectively referred to as the "Founding Companies") engaged in providing HVAC services. The Founding Companies had operations in ten states. Subsequent to June 30, 1997, and through December 31, 1997, the Company acquired 27 HVAC and related businesses. These companies added operating locations in an additional 10 states (which includes Puerto Rico). These acquisitions included six "tuck-in" operations which were combined with existing Comfort Systems locations in 1997. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: BASIS OF PRESENTATION For financial statement purposes, Comfort Systems has been identified as the accounting acquirer. Accordingly, the historical financial statements include those of Comfort Systems since December 1996. Of the 27 acquisitions noted above, 14 were accounted for as poolings-of-interests (the "Pooled Companies") and 13 were accounted for as purchases (the "Purchased Companies"). These consolidated financial statements reflect the acquisitions of the Founding Companies and Purchased Companies as of their respective acquisition dates and reflects eight of the Pooled Companies (the "Restated Companies") for all periods presented. Certain of the Pooled Companies are considered immaterial poolings based upon the relative significance of their individual operations and have not been restated for all periods presented. The acquisitions of the Founding and Purchased Companies were accounted for using the purchase method of accounting. The allocations of the purchase prices to the assets acquired and liabilities assumed of these companies have been recorded based on preliminary estimates of fair value and may be changed as additional information becomes available. Prior to their acquisition by Comfort Systems, three of the Pooled Companies reported annual results based on fiscal year-ends other than December 31. An adjustment to conform the year-ends of these companies to December 31 year-ends was made in 1996 resulting in an increase of approximately $376,000 to retained earnings and cash flows for 1996. PRINCIPLES OF CONSOLIDATION The accompanying consolidated financial statements include the accounts of Comfort Systems and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. 27 CASH FLOW INFORMATION The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash paid for interest in 1995, 1996 and 1997 was approximately $242,000, $246,000, and $492,000, respectively. Cash paid for income taxes in 1995, 1996 and 1997 was approximately $228,000, $697,000, and $985,000, respectively. The Company recorded capital leases in 1995, 1996 and 1997 of approximately $--, $--, and $114,000, respectively. 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 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 expected 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 over the remaining useful life of the equipment. 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. GOODWILL Goodwill represents the excess of the aggregate purchase price paid by the Company in acquisitions accounted for as purchases over the fair value of the net tangible assets acquired. Goodwill is amortized on a straight-line basis over 40 years. The Company periodically evaluates the recoverability of the remaining balance of goodwill recorded from business acquisitions. The Company uses an estimate of future income from operations and cash flows, as well as other economic and business factors as a measure of recoverability of these assets. As of December 31, 1997, accumulated amortization of goodwill was approximately $1.9 million. 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 revenues, and their effects are recognized in the period in which the revisions are determined. 28 Receivable 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 typically 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 will file a consolidated return for federal income tax purposes. Income taxes are provided for under the liability method, which takes into account differences between financial statement treatment and tax treatment of certain transactions. Deferred tax assets represent the tax effect of activity that has been reflected in the financial statements but which will not be deductible for tax purposes until future periods. Deferred tax liabilities represent the tax effect of activity that has been reflected in the financial statements but which will not be taxable until future periods. Certain of the Pooled Companies were S Corporations for income tax purposes and, accordingly, any income tax liabilities for the periods prior to the acquisition date are the responsibility of the respective stockholders. All acquired entities are subject to corporate income taxes subsequent to their acquisition. 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 revenues, expenses, assets, liabilities and contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. CONCENTRATIONS OF CREDIT RISK The Company provides services to a broad range of geographical regions. The Company's credit risk primarily consists of receivables from a variety of customers including, general contractors, property owners and developers, and commercial and industrial companies. The Company reviews its accounts receivable and provides allowances as deemed necessary. IMPAIRMENT OF LONG-LIVED ASSETS 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 are compared to the asset's carrying amount to determine if a write-down to fair value is necessary. Adoption of this standard did not have a material effect on the financial position or results of operations of the Company. 29 3. BUSINESS COMBINATIONS: POOLINGS During 1997, the Company acquired all of the outstanding stock of the Pooled Companies in exchange for 4,507,406 shares of Common Stock. These acquisitions have been accounted for as poolings-of-interests as described in Note 2. These companies provide HVAC and related services. The historical financial statements for 1995 and 1996 represent the operations of the Restated Companies prior to their acquisition by the Company. The combined revenues and net income of the Pooled Companies for the preacquisition period in 1997 were $94.6 million and $5.5 million, respectively. PURCHASES Subsequent to the Offering, Comfort Systems acquired the thirteen Purchased Companies, which were accounted for as purchase transactions. These companies provide HVAC and related services. The aggregate consideration paid in these transactions was $14.5 million in cash, 1,092,489 shares of Common Stock with a market value at the date of acquisition totaling $13.3 million and $5.0 million in the form of convertible subordinated notes (the "Notes"). These notes are convertible at various dates in 1998 or 1999 and thereafter into 225,473 or 220,449 shares of Common Stock, respectively. The accompanying balance sheet as of December 31, 1997 includes allocations of the respective purchase prices to the assets acquired and liabilities assumed based on preliminary estimates of fair value and is subject to final adjustment. The allocations resulted in $25.4 million of goodwill, which represents the excess of purchase price over the estimated fair value of the net assets acquired for the Purchased Companies. In conjunction with the acquisitions, goodwill was determined as follows (in thousands): Fair value of assets acquired, net of cash acquired ............ $(21,677) Liabilities assumed ............................................ 17,010 Cash paid, net of cash acquired ................................ 11,781 Estimated market value of stock consideration .................. 13,264 Issuance of convertible notes .................................. 4,978 -------- Goodwill ....................................................... $ 25,356 ======== The unaudited pro forma data presented below consists of the income statement data presented in these consolidated financial statements plus (a) income statement data for the Founding Companies for the year ended December 31, 1996, and the six months ended June 30, 1997, and (b) income statement data for the Purchased Companies as if they were effective on January 1, 1996 through the respective dates of acquisitions (in thousands, except per share data): YEAR ENDED DECEMBER 31, --------------------------- 1996 1997 -------- -------- (UNAUDITED) Revenues ........................... $327,721 $381,528 Net income ......................... 16,374 19,294 Net income per share ............... 0.64 0.76 Pro forma adjustments included in the preceding tables regarding the Founding Companies and the Purchased Companies primarily relate to (a) certain reductions in salaries and benefits to the former owners (the "Compensation Differential") of the Founding Companies, Pooled Companies and Purchased Companies which they agreed would take effect as of the acquisition date, (b) pro forma compensation expense of $430,000 for the six months ended June 30, 1997, to reflect the ongoing salaries received by corporate management as though these salaries were being paid prior to the Offering, (c) elimination of merger costs in connection with the acquisition of the Pooled Companies, (d) amortization of goodwill 30 related to the Purchased and Founding Companies, (e) elimination of the non-recurring, non-cash compensation charge of $11.6 million recorded by Comfort Systems in the first quarter of 1997 related to Common Stock issued to management of and consultants to the Company, and (f) interest expense on borrowings of $11.0 million that would have been necessary to fund certain S Corporation distributions as if they had occurred at the beginning of each period presented. In addition, an incremental tax provision has been recorded as if all applicable Purchased and Founding Companies and Pooled Companies which were C Corporations had been subject to federal and state income taxes. The pro forma combined results presented above are not necessarily indicative of actual results which might have occurred had the operations and management teams of the Company, the Founding Companies, the Purchased Companies and Pooled Companies been combined at the beginning of the periods presented. ADDITIONAL ACQUISITIONS Subsequent to December 31, 1997, and through February 25, 1998, the Company completed five additional acquisitions (the "Additional Acquisitions") for approximately $15.1 million in cash, 2,002,894 shares of Common Stock and approximately $1.3 million in Notes. The Company filed a Current Report on Form 8-K related to one of these Additional Acquisitions. Annualized revenues from the businesses acquired in the Additional Acquisitions were approximately $109 million. All of these acquisitions will be accounted for as purchase transactions. 4.

(the "Credit Facility"). The Credit Facility was amended and restated in September 1997 primarily to provide for additional banks to lend to the Company under the Credit Facility. The Credit Facility provides the Company with an unsecured revolving line of credit of $75 million. The Company has a choice of two interest rate options when borrowing under the Credit Facility. Under one option, the interest rate is determined based on the higher of the Federal Funds Rate plus one-half percentage point or the bank's prime rate. An additional margin of zero to one-quarter percentage point is then added to the higher of these two rates. The additional margin depends on the ratio of the Company's debt to earnings before interest, taxes, depreciation and amortization for the preceding twelve months ("EBITDA"). For purposes of this ratio, EBITDA may include the preceding twelve months' results for any companies acquired during the last year. Under the other interest rate option, borrowings bear interest based on designated short-term Eurodollar rates (which generally approximate the London Interbank Offered Rates or LIBOR, as published in major financial media) plus one to two percentage points, again depending on the ratio of debt to EBITDA. In addition, commitment fees of 0.125% to 0.375% per annum, also depending on the ratio of debt to EBITDA, are payable on the unused portion of the line of credit. The Credit Facility prohibits the payment of dividends by the Company without lender's approval and requires the Company to comply with certain financial covenants. The Credit Facility expires on July 2, 2000, at which time all amounts outstanding under the facility are due. As of December 31, 1997, the Company had borrowed $15.3 million under the Credit Facility at an average interest rate of approximately 6.7% per annum for the second half of 1997. As of March 24, 1998, $43.8 million (unaudited) was outstanding under this facility. The Notes in the amount of $5 million referred to above were issued to former owners of certain Purchased Companies as partial consideration of the acquisition purchase price. The Notes bear interest, payable quarterly, at a weighted average interest rate of 6.0% and are convertible by the holder into shares of the Company's Common Stock at a weighted average price of $22.08 per share. The terms of the Notes require $0.3 million of principal payments in 1999 and $4.7 million of principal payments at maturity in 2000. The Company estimates the fair value of long-term debt as of December 31, 1997, to be approximately the same as the recorded value. 7. INCOME TAXES: The Company has implemented SFAS No. 109, "Accounting for Income Taxes," which provides for a liability approach to accounting for income taxes. The provision for income taxes consists of the following (in thousands): YEAR ENDED DECEMBER 31, ----------------------- 1995 1996 1997 ------- ------- ----- Current - Federal .......................................... $ 379 $ 893 $6,346 State and Puerto Rico............................. 148 245 1,747 ------- ------- ------ 527 1,138 8,093 ------- ------- ------ Deferred - Federal........................................... 9 243 (710) State and Puerto Rico.............................

EMPLOYEE BENEFIT PLANS: Certain of the Company's subsidiaries sponsor various retirement plans for most full-time and some part-time employees. These plans consist of defined contribution plans and multi-employer pension plans and cover employees at substantially all of the Company's operating locations. The defined contribution plans provide for contributions ranging from 1% to 5% of covered employees' salaries or wages and totaled $1.4 million for 1995, $1.8 million for 1996 and $1.4 million for 1997. Of these amounts, 34 approximately $830,000 and $400,000 was payable to the plans at December 31, 1996, and December 31, 1997, respectively. Certain of the Company's subsidiaries also participate in several multi-employer pension plans for the benefit of their employees who are union members. Company contributions to these plans were approximately $0.7 million for 1995, $0.6 million for 1996 and $0.8 million for 1997. The data available from administrators of the multi-employer pension plans is not sufficient to determine the accumulated benefit obligations, nor the net assets attributable to the multi-employer plans in which Company employees participate. 9. COMMITMENTS AND CONTINGENCIES: LEASES The Company leases certain facilities and equipment under noncancelable operating leases. Rent expense for the years ended December 31, 1995, 1996, and 1997 was $0.5 million, $0.5 million, and $1.8 million, respectively. Concurrent with the acquisitions of certain Founding, Pooled and Purchased Companies, the Company entered into various agreements with previous owners to lease land and buildings used in the Company's operations. The terms of these leases range from five years to twenty years and provide for certain escalations in the rental expenses each year. Included in the 1997 rent expenses above is approximately $1.0 million of rent paid to these related parties. The following represents future minimum rental payments under noncancelable operating leases (in thousands): Year ending December 31 - 1998........................................................ $3,948 1999........................................................ 3,508 2000........................................................ 3,089 2001........................................................ 2,580 2002........................................................ 2,165 Thereafter.................................................. 9,204 ------ $24,494 ======= CLAIMS AND LAWSUITS The Company is from time to time party to litigation in the ordinary course of business. There are currently no pending legal proceedings that, in management's opinion, would have a material adverse effect on the Company's operating results or financial condition. The Company maintains various insurance coverages in order to minimize financial risk associated with certain claims. The Company has provided accruals for probable losses and legal fees associated with certain of these actions in the accompanying consolidated financial statements. 10. 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 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 number of shares of authorized Common Stock have been retroactively reflected on the balance sheet and in the accompanying notes as applicable. 35 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 Captial Ventures II, L.L.C. ("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 of and consultants to the Company at a price of $.01 per share. As a result, the Company recorded a non-recurring, non-cash compensation charge of $11.6 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. RESTRICTED COMMON STOCK In March 1997, Notre exchanged its 2,742,912 shares of Common Stock for an equal number of shares of restricted voting common stock ("Restricted Voting Common Stock"). The holder of Restricted Voting Common Stock is entitled to elect one member of the Company's Board of Directors and to 0.55 of one vote for each share on all other matters on which they are entitled to vote. Holders of Restricted Voting Common Stock are not entitled to vote on the election of any other directors. Each share of Restricted Voting 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 Voting Common Stock by the holder thereof (other than a distribution which is a distribution by a holder to its partners or beneficial owners, or a transfer to a related party of such holders (as defined in Sections 267, 707, 318 and/or 4946 of the Internal Revenue Code of 1986, as amended)), (ii) in the event any person acquires beneficial ownership of 15% or more of the total number of outstanding shares of Common Stock of the Company, or (iii) in the event any person offers to acquire 15% or more of the total number of outstanding shares of Common Stock of the Company. After July 1,1998, the Board of Directors may elect to convert any remaining shares of Restricted Voting Common Stock into shares of Common Stock in the event 80% or more of the originally outstanding shares of Restricted Voting Common Stock have been previously converted into shares of Common Stock. EARNINGS PER SHARE In February 1997, the Financial Accounting Standards Board issued SFAS No. 128, "Earnings Per Share." SFAS No. 128 revises the methodology to be used in computing earnings per share (EPS) such that the computations previously required for primary and fully diluted EPS are to be replaced with "basic" and "diluted" EPS. Basic EPS is computed by dividing net income by the weighted average number of shares of common stock outstanding during the year. Diluted EPS is computed in the same manner as fully diluted EPS, except that, among other changes, the average share price for the period is used in all cases when applying the treasury stock method to potentially dilutive outstanding options. The Notes are not included in the weighted average shares outstanding because they were not significant. The Company has adopted SFAS No. 128 and restated EPS for all periods presented. The following table summarizes weighted average shares outstanding for each of the periods presented (in thousands): 36 YEAR ENDED DECEMBER 31, ----------------------- 1995 1996 1997 ------- ------- ----- Shares issued in connection with the acquisitions of Founding Companies............. -- -- 5,008 Shares sold pursuant to the Offering.............. -- -- 3,142 Shares held by Notre, management and consultants.. 4,240 4,240 4,240 Shares issued in connection with the acquisitions of Pooled Companies............... 3,446 4,295 4,507 Shares issued in connection with the underwriter's overallotment ................... -- -- 434 Shares issued in connection with the acquisitions of the Purchased Companies........ -- -- 184 ------- ------- ------ Weighted average shares outstanding - Basic...... 7,686 8,535 17,515 Weighted average portion of shares related to stock options under the treasury stock method................................... -- -- 193 ------- ------- ------ Weighted average shares outstanding - Diluted..... 7,686 8,535 17,708 ======= ======= ====== 11. STOCK OPTION PLANS: LONG-TERM INCENTIVE PLAN In March 1997, the Company's stockholders approved the Company's 1997 Long-Term Incentive Plan which provides for the granting or awarding of incentive or non-qualified stock options, stock appreciation rights, restricted or deferred stock, dividend equivalents or other incentive awards to directors, officers, key employees and consultants to the Company. The Company's 1997 Long-Term Incentive Plan provides for the granting of options to key employees to purchase an aggregate of not more than 13% of the total number of shares of the Company's Common Stock outstanding at the time of grant. Such options have been issued by the Company at fair market value on the date of grant and become exercisable in five equal annual installments beginning on the first anniversary of the date of grant. The options expire after seven years from the date of grant if unexercised. Outstanding options may be canceled and reissued under terms specified in the plan. The following table summarizes activity under the Company's stock option plan: 1997 --------- Options outstanding, beginning of year...................... -- Granted (range of exercise prices, $13.00 to $17.88)..... 2,537,203 Forfeited (range of exercise prices, $13.00 to $17.88)... -- --------- Options outstanding, end of year............................ 2,537,203 ========= The Company accounts for its stock-based compensation under Accounting Principles Board Statement No. 25, "Accounting for Stock Issued to Employees" (APB 25). Under this accounting method, no expense in connection with a stock option is recognized in the consolidated statements of operations if the exercise price of the option is equal to the market price of the stock on the date of grant. In October 1995, the Financial Accounting Standards Board issued SFAS No. 123, "Accounting for Stock-Based Compensation," which requires that if a company accounts for stock-based compensation in accordance with APB 25, the company must also disclose the effects on its results of operations as if an estimate of the value of stock-based compensation at the date of grant was recorded as an expense in the company's statement of operations. These effects for the Company are as follows (in thousands, except per share data): 37 1997 ------- Net Loss As reported............................... $(2,830) Pro forma for SFAS No. 123................ $(3,229) Loss Per Share As reported............................... $ (.16) Pro forma for SFAS No. 123................ $ (.18) Pro forma basic loss per share and diluted loss per share are the same for SFAS No. 123 purposes. The effects of applying SFAS No. 123 in the pro forma disclosure may not be indicative of future amounts as additional awards in future years are anticipated. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions: Expected dividend yield............................ 0.00% Expected stock price volatility.................... 39.41% Risk free interest rate............................ 5.77% - 6.15% Expected life of options........................... 7 years Options outstanding at December 31, 1997, had exercise prices ranging from $13.00 to $17.88, a weighted average remaining contractual life of 6.6 years, a weighted average fair value of $4.24 per option and a weighted average exercise price of $13.72 per option. NON-EMPLOYEE DIRECTORS STOCK PLAN In March 1997, the Company's stockholders approved the 1997 Non-Employee Directors' Stock Plan (the "Directors' Plan"), which provides for the granting or awarding of stock options and stock appreciation rights to non-employees. The number of shares authorized and reserved for issuance under the Directors' 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 10,000 shares at the time of the initial election. In addition, each director will be automatically granted options to purchase an additional 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 granted with an exercise price equal to the fair market value at the date of grant and are immediately vested upon grant. Options have been granted to three current members of the board of directors to purchase 10,000 shares of Common Stock at the initial Offering price. These options will expire at 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. 12. SIGNIFICANT VENDORS: Significant vendors are defined as those that account for greater than 10% of the Company's purchases. For the year ended December 31, 1997, one vendor accounted for 10.9% of the Company's purchases. There were no significant vendors in 1996 or 1995. The Company believes that an 38 interruption in supply from the significant vendor referred to above would not have a material adverse impact on the financial position or results of operations of the Company. 39 ITEM 9.

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Quality Air Heating & Cooling, Inc., as of March 31, 1995 and 1996, and December 31, 1996, and the results of their operations and their cash flows for the years ended March 31, 1995 and 1996, the nine months ended December 31, 1996, the year ended December 31, 1996, and the six months ended June 30, 1997, in conformity with generally accepted accounting principles.

The accompanying notes are an integral part of these financial statements. F-7 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-8 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 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. PROPERTY AND EQUIPMENT: Property and equipment consist of the following (dollars in thousands):

There was no balance outstanding under this line of credit at March 31, 1995 and 1996, and December 31, 1996. 6. LEASES: The Company leases a facility from a company which is owned by one of the Company's shareholders. The lease expires on April 30, 2005.

The rent paid under this related-party lease was approximately $221,000 for each of the years ended March 31, 1995 and 1996, and December 31, 1996, and $110,400 for the six months ended June 30, 1997. The Company also leases a facility from a third party, which expires on June 30, 1998. 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. The Company 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 a shareholder, the proceeds of which were used to fund the construction of the Company's leased warehouse facility and a second adjacent warehouse. As of March 1997, approximately $1.6 million of the bond debt remained outstanding. Future minimum lease payments under these non-cancellable operating leases are as follows (in thousands): Year ending December 31, 1997............................ $ 241 1998............................ 231 1999............................ 221 2000............................ 221 2001............................ 221 Thereafter...................... 718 --------- $ 1,853 ========= 7.

The accompanying notes are an integral part of these consolidated financial statements. F-17 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 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-18 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-19 ATLAS COMFORT SERVICES USA, INC.

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. 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- F-31 TRI-CITY MECHANICAL, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) 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 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 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-32 TRI-CITY MECHANICAL, INC.

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.

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.

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-52 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.

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.

On July 2, 1997, Comfort Systems completed its initial public offering and the merger with the Company. Concurrently with the merger, the Company entered into agreements with the shareholders to lease land and buildings used in the Company's operations for a 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. In connection with the merger, Comfort Systems assumed all debt of the Company. Subsequent to the IPO, substantially all of the debt has been repaid.

The accompanying notes are an integral part of these financial statements. F-73 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-74 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 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, 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 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 percent of the employee contribution up to 5 percent 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 respectively.

F-93 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-94 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.

LONG-TERM DEBT: Long-term debt consists of two notes payable to officers and an installment note payable for transportation equipment, which is secured by the related transportation equipment. 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. The line of credit expires August 5, 1997, and bears interest at prime plus one percent per annum. There was no balance outstanding under this line of credit at December 31, 1996. 6. LEASES: The Company leases facilities from a partnership which is partially owned by one of the shareholders. The lease expires in October, 2006. The rent paid under this lease was approximately $62,640 for the year ended December 31, 1996, and $31,320 for the six months ended June 30, 1997. The lease requires the Company to pay taxes, maintenance, insurance and certain other operating costs of the leased property. The Company leases vehicles for operations. The payments under these vehicle leases were approximately $189,000 for the year ended December 31, 1996, and $92,500 for the six months ended June 30, 1997 . F-96 SEASONAIR, INC.

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 action will have a material adverse effect on the Company's financial position or results of operations. INSURANCE The Company carries a broad range of insurance coverage, including general and business auto liability, commercial property, workers' compensation and a general umbrella policy. The Company has not incurred significant claims or losses on any of its insurance policies. 9. EMPLOYEE BENEFIT PLAN: The Company has a 401(k) profit-sharing plan which provides for the Company to match employee contributions up to a maximum of $260 per person per year as well as an employee stock ownership plan. Total contributions for both plans by the Company under the plan were approximately $80,000 for purchase of treasury stock for the employee stock ownership plan, and $5,000 for the 401(k) plan for the year ended December 31, 1996. 10. FINANCIAL INSTRUMENTS: The Company's financial instruments consist of cash and cash equivalents, notes receivable, investments, notes payable, and debt.

SUBSEQUENT EVENTS: In March 1997, the Company and its shareholders entered into a definitive agreement with a wholly-owned subsidiary of Comfort Systems, providing for the exchange of shares by the Company with the subsidiary of Comfort Systems. On July 2, 1997, Comfort Systems completed its initial public offering and the merger with the Company. In connection with the merger, Comfort Systems assumed all debt of the Company.

("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 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 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 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. Revenues of approximately $783,000 and $2,291,000 with gross profits of $339,000 and $874,000 were recognized by the Company in 1995 and 1996, respectively, for energy conversions and new installations related to an incentive program developed by the Public Service Company of Colorado (PSC).

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 Statement of Financial Accounting Standard (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.

If an Event of Default shall have occurred and be continuing, if and to the extent that the Lender shall so notify any Pledgor in writing, only the Lender shall be entitled to vote or consent or take any other action with respect to the Pledged Stock pledged by such Pledgor (and such Pledgor will, if so requested, execute or cause to be executed appropriate proxies therefor). 2.4. RIGHT TO REALIZE UPON COLLATERAL. Except to the extent prohibited by applicable law that cannot be waived, this Section 2.4 shall govern the Lender's right to realize upon the Collateral if any Event of Default shall have occurred and be continuing. The provisions of this Section 2.4 are in addition to any rights and remedies available at law or in equity and in addition to the provisions of the Note. 2.4.1. GENERAL AUTHORITY. To the extent specified in written notice from the Lender to the Pledgor in question, each Pledgor grants the Lender full and exclusive power and authority, subject to the other terms hereof and applicable law, to take any of the following actions (for the sole benefit of the Lender and the holders from time to time of any Obligations, but at such Pledgor's expense): (a) to ask for, demand, take, collect, sue for and receive all payments in respect of any Pledged Stock which such Pledgor could otherwise ask for, demand, take, collect, sue for and receive for his own use; (b) to extent the time of payment of any amounts in respect of the Pledged Stock and to make any allowance or other adjustment with respect thereto; -4- (c) to settle, compromise, prosecute or defend any action or proceeding with respect to any Pledged Stock and to enforce all rights and remedies thereunder which such Pledgor could otherwise enforce; (d) to notify the third party payor with respect to any Pledged Stock of the existence of the security interest created hereby and to cause all payments in respect thereof thereafter to be made directly to the Lender; and (e) to sell, transfer, assign or otherwise deal in or with any Collateral or the proceeds thereof, as fully as such Pledgor otherwise could do. 2.4.2. MARSHALING, ETC. The Lender shall not be required to make any demand upon, or pursue or exhaust any of its rights or remedies against, the Pledgor or any other Person with respect to the payment of the Obligations or to pursue or exhaust any of its rights or remedies with respect to any collateral therefor or any direct or indirect guarantee thereof. The Lender shall not be required to marshal the Collateral or any guarantee of the Obligations or to resort to the Collateral or any such guarantee in any particular order, and all of its rights hereunder or under the Note shall be cumulative. To the extent it may lawfully do so, each Pledgor absolutely and irrevocably waives and relinquishes the benefit and advantage of, and covenants not to assert against the Lender, any valuation, stay, appraisement, extension, redemption or similar laws now or hereafter existing which, but for this provision, might be applicable to the sale of any Collateral made under the judgment, order or decree of any court, or privately under the power of sale conferred by this Agreement, or otherwise. Without limiting the generality of the foregoing, each Pledgor (a) agrees that it will not invoke or utilize any law which might prevent, cause a delay in or otherwise impede the enforcement of the rights of the Lender in the Collateral, (b) waives all such laws, and (c) agrees that it will not invoke or raise as a defense to any enforcement by the Lender of any rights and remedies relating to the Collateral or the Obligations any legal or contractual requirement with which the Lender may have in good faith failed to comply. In addition, each Pledgor waives any right to prior notice (except to the extent expressly required by this Agreement) or judicial hearing in connection with foreclosure on or disposition of any Collateral, including any such right which such Pledgor would otherwise have under the Constitution of the United States of America, any state or territory thereof or any other jurisdiction. 2.4.3. SALES OF COLLATERAL. All or any part of the Collateral may be sold for cash or other value in any number of lots at public or private sale, without demand, advertisement or notice; PROVIDED, HOWEVER, unless the Collateral to be sold threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Lender shall give the Pledgor granting the security interest in such Collateral 10 days' prior written notice of the time and place of any public sale, or the time after which a -5- private sale may be made, which notice each of the Pledgors and the Lender hereby agrees to be reasonable. At any sale of Collateral, the Lender or any of its respective officers acting on its behalf, or the Lender's assigns, may bid for and purchase all or any part of the Collateral, may use all or any portion of the Obligations owed to the Lender as payment for the Collateral so purchased, and upon compliance with the terms of such sale may hold and dispose of the Collateral without further accountability to any Pledgor, except for the proceeds of such sale or sales pursuant to Section 2.4.5. Each Pledgor will execute and deliver or cause to be executed and delivered such instruments, documents, assignments, waivers, certificates and affidavits, will supply or cause to be supplied such further information and will take such further action as the Lender shall request in connection with any such sale. 2.4.4. SALE WITHOUT REGISTRATION. If, at any time when the Lender shall determine to exercise its rights hereunder to sell all or part of the Collateral, the Collateral shall not be effectively registered under the Securities Act (or other applicable law), the Lender may, in its sole discretion, sell such securities by private or other sale not requiring such registration in such manner and in such circumstances as the Lender may deem necessary or advisable in order that such sale may be effected in accordance with applicable securities laws without such registration and the related delays, uncertainty and expense. Without limiting the generality of the foregoing, in any event the Lender may, in its sole discretion, (a) approach and negotiate with a single purchaser or one or more possible purchasers to effect such sale, (b) restrict such sale to one or more purchasers each of whom will represent and agree that such purchaser is purchasing for its own account, for investment and not with a view to the distribution or sale of such securities and (c) cause to be placed on certificates representing the securities in question a legend to the effect that such securities have not been registered under the Securities Act (or other applicable law) and may not be disposed of in violation of the provisions thereof. Each Pledgor agrees that such manner of disposition is commercially reasonable, that he will upon the Lender's request give any such purchaser access to such information regarding the issuer of the Collateral as the Lender may reasonably request and that the Lender shall not incur any responsibility for selling all or part of the Collateral at any private or other sale not requiring such registration, notwithstanding the possibility that a substantially higher price might be realized if the sale were deferred until after registration under the Securities Act (or other applicable law) or until made in compliance with certain other rules or exemptions from the registration provisions under the Securities Act (or other applicable law). Each Pledgor acknowledges that no adequate remedy at law exists for breach by him of this Section 2.4.4 and that such breach would not be adequately compensable in damages and therefore agrees that this Section 2.4.4 may be specifically enforced. 2.4.5. APPLICATION OF PROCEEDS. The proceeds of all sales and collections in respect of any Collateral shall be applied as follows: -6- (a) first, to the payment of the costs and expenses of such sales and collections, the reasonable expenses of the Lender and the reasonable fees and expenses of its special counsel; (b) second, any surplus then remaining to the payment of the Obligations in such order and manner as the Lender may in its reasonable discretion determine; and (c) third, any surplus then remaining shall be paid to the Pledgors, subject, however, to the rights of the holder of any then existing lien of which the Lender has actual notice. 2.5. CUSTODY OF COLLATERAL. Except as provided by applicable law that cannot be waived, the Lender will have no duty as to the custody and protection of the Collateral, the collection of any part thereof or of any income thereon or the preservation or exercise of any rights pertaining thereto, including rights against prior parties, except for the use of reasonable care in the custody and physical preservation of any Collateral in its possession. The Lender will not be liable or responsible for any loss or damage to any Collateral, or for any diminution in the value thereof, by reason of the act or omission of any agent selected by the Lender acting in good faith. 3. WAIVERS WITH RESPECT TO COLLATERAL. Each Pledgor waives, to the fullest extent permitted by the provisions of applicable law, all of the following (including all defenses, counterclaims and other rights of any nature based upon any of the following): (a) presentment, demand for payment and protest of nonpayment of any of the Obligations and notice of protest, dishonor or nonperformance; (b) notice of acceptance of, and notice that credit has been extended in reliance on, this Agreement; (c) notice of any default or any inability to enforce performance of the obligations of the Borrower or any other Person with respect to the Note, or notice of any acceleration of maturity of the Note; (d) demand for performance or observance of, and any enforcement of any provision of, the Obligations, this Agreement or the Note or any pursuit or exhaustion of rights or remedies with respect to any Collateral or against the Borrower or any other Person in respect of the Obligations or any requirement of diligence or promptness on the part of the Lender in connection with any of the foregoing; (e) any act or omission on the part of the Lender which may impair or prejudice such rights of such Pledgor, including rights to obtain subrogation, exoneration, -7- contribution, indemnification or any other reimbursement from the Borrower or any other Person, or otherwise operate as a deemed release or discharge; (f) failure or delay to perfect or continue the perfection of any security interest in any Collateral or any other action which harms or impairs the value of, or any failure to preserve or protect the value of, any Collateral; (g) any statute of limitations or any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than the obligation of the principal; (h) any "single action" or "anti-deficiency" law which would otherwise prevent the Lender from bringing any action, including any claim for a deficiency, against such Pledgor before or after the Lender's commencement or completion of any foreclosure action, whether judicially, by exercise of power of sale or otherwise, or any other law which would otherwise require any election of remedies by the Lender; (i) all demands and notices of every kind with respect to the foregoing; and (j) to the extent not referred to above, all defenses (other than payment) which the Borrower or such Pledgor may now or hereafter have to the payment of the Obligations, together with all suretyship defenses, which could otherwise be asserted by such Pledgor. Each Pledgor represents that it has obtained the advice of counsel as to the extent to which suretyship and other defenses may be available to it with respect to its obligations hereunder in the absence of the waivers contained in this Section 3. No delay or omission on the part of the Lender in exercising any right under this Agreement or the Note or under any guarantee of the Obligations or with respect to the Collateral shall operate as a waiver or relinquishment of such right. No action which the Lender or the Borrower may take or refrain from taking with respect to the Obligations, including any amendments thereto or modifications thereof or waivers with respect thereto, shall affect the provisions of this Agreement or the obligations of any Pledgor hereunder. None of the Lender's rights shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of any Obligor, or by any noncompliance by the Borrower with the terms, provisions and covenants of the Note, regardless of any knowledge thereof which the Lender may have or otherwise be charged with. 4. LENDERS' POWER TO WAIVE, ETC. Each Pledgor grants to the Lender full power in its discretion, without notice to or consent of such Pledgor, such notice and consent being expressly waived to the fullest extent permitted by applicable law, and without in any way affecting the liability of any Pledgor under its pledge hereunder: -8- (a) to waive compliance with, and any default under, and to consent to any amendment to or modification or termination of any terms or provisions of, or to give any waiver in respect of, this Agreement, the Note, the Collateral, the Obligations or any guarantee thereof (each as from time to time in effect); (b) to grant any extensions of the Obligations (for any duration), and any other indulgence with respect thereto, and to effect any total or partial release (by operation of law or otherwise), discharge, compromise or settlement with respect to the obligations of the Obligors or any other Person in respect of the Obligations, whether or not rights against any Pledgor under this Agreement are reserved in connection therewith; (c) to take security in any form for the Obligations, and to consent to the addition to or the substitution, exchange, release or other disposition of, or to deal in any other manner with, any part of any property contained in the Collateral whether or not the property, if any, received upon the exercise of such power shall be of a character or value the same as or different from the character or value of any property disposed of, and to obtain, modify or release any present or future guarantees of the Obligations and to proceed against any of the Collateral or such guarantees in any order; (d) to collect or liquidate or realize upon any of the Obligations or the Collateral in any manner or to refrain from collecting or liquidating or realizing upon any of the Obligations or the Collateral; and (e) to extend credit under the Note or otherwise in such amount as the Lender may determine, including increasing the amount of credit and the interest rate and fees with respect thereto, even though the condition of the Obligors (financial or otherwise on an individual or consolidated basis) may have deteriorated since the date hereof. 5. INFORMATION REGARDING THE BORROWER, ETC. Each Pledgor has made such investigation as it deems desirable of the risks undertaken by it in entering into this Agreement and is fully satisfied that it understands all such risks. Each Pledgor waives any obligation which may now or hereafter exist on the part of the Lender to inform it of the risks being undertaken by entering into this Agreement or of any changes in such risks and, from and after the date hereof, each Pledgor undertakes to keep itself informed of such risks and any changes therein. Each Pledgor expressly waives any duty which may now or hereafter exist on the part of the Lender to disclose to such Pledgor any matter related to the business, operations, character, collateral, credit, condition (financial or otherwise), income or prospects of the Borrower or its properties or management, whether now or hereafter known by the Lender. Each Pledgor represents, warrants and agrees that it assumes sole responsibility for obtaining from the -9- Borrower all information concerning the Note and all other information as to the Borrower or its properties or management as such Pledgor deems necessary or desirable. 6. DEFAULTS. 6.1. EVENTS OF DEFAULT. The following events are referred to as "EVENTS OF DEFAULT": 6.1.1. PAYMENT. The Borrower shall fail to make any payment in respect of principal of, or interest in respect of, any of the Obligations owed by it as the same shall become due and payable, whether at maturity or by acceleration or otherwise, and such failure shall continue for a period of 10 days after notice thereof by the Lender to the Pledgors. 6.1.2. COVENANTS. Any Obligor shall fail to perform or observe any other covenant, agreement or provision to be performed or observed by it under this Agreement or the Note, and such failure shall not be rectified or cured to the written satisfaction of the Lender within 30 days after the earlier of (a) notice thereof by the Lender to such Obligor or (b) such Obligor shall have actual knowledge thereof. 6.1.3.

Any Obligor shall: (a) commence a voluntary case under the Bankruptcy Code or authorize, by appropriate proceedings of its board of directors or other governing body, the commencement of such a voluntary case; (b) (i) have filed against it a petition commencing an involuntary case under the Bankruptcy Code that shall not have been dismissed within 60 days after the date on which such petition is filed, or (ii) file an answer or other pleading within such 60-day period admitting or failing to deny the material allegations of such a petition or seeking, consenting to or acquiescing in the relief therein provided, or (iii) have entered against it an order for relief in any involuntary case commenced under the Bankruptcy Code; -10- (c) seek relief as a debtor under any applicable law, other than the Bankruptcy Code, of any jurisdiction relating to the liquidation or reorganization of debtors or to the modification or alteration of the rights of creditors, or consent to or acquiesce in such relief; (d) have entered against it an order by a court of competent jurisdiction (i) finding it to be bankrupt or insolvent, (ii) ordering or approving its liquidation or reorganization as a debtor or any modification or alteration of the rights of its creditors or (iii) assuming custody of, or appointing a receiver or other custodian for, all or a substantial portion of its property; or (e) make an assignment for the benefit of, or enter into a composition with, its creditors, or appoint, or consent to the appointment of, or suffer to exist a receiver or other custodian for, all or a substantial portion of its property. 6.2. CERTAIN ACTIONS FOLLOWING AN EVENT OF DEFAULT. If any one or more Events of Default shall occur and be continuing, then, subject to Section 7, in each and every such case the Lender may proceed: (a) to protect and enforce the Lender's rights by suit in equity, action at law and/or other appropriate proceeding, either for specific performance of any covenant or condition contained in this Agreement or in any instrument or assignment delivered to the Lender pursuant to this Agreement, or in aid of the exercise of any power granted in this Agreement or any such instrument or assignment; and (b) to realize upon any and all rights in the Collateral. To the extent not prohibited by applicable law which cannot be waived, all of the Lender's rights under this Agreement and the Note shall be cumulative. 7. NON-RECOURSE OBLIGATION. Notwithstanding any provision of this Agreement to the contrary, (a) this Agreement shall be without recourse to the Pledgors, (b) the Obligations shall be recourse only to the Collateral and, upon issuance of any Guarantee, the Pledgor issuing such Guarantee and the assets of such Pledgor and (c) the Pledgors shall be liable for payment of the Obligations only to the extent of any foreclosure, suit (including any suit for collection hereunder), proceeding or other action against the Collateral or, upon issuance of any Guarantee, the Pledgor issuing such Guarantee and the assets of such Pledgor. 8. REPRESENTATIONS AND WARRANTIES. In order to induce the Lender to extend credit to the Borrower under the Note, the Pledgors jointly and severally represent and warrant that: 8.1. ENFORCEABILITY. This Agreement constitutes the legal, valid and binding obligation of each Pledgor, enforceable against each Pledgor in accordance with its terms. -11- 8.2. NO LEGAL OBSTACLE TO AGREEMENTS. Neither the execution, delivery and performance of this Agreement, nor the consummation of any transaction referred to in or contemplated by this Agreement or the Note, has constituted or resulted, or will constitute or result, in: (a) any breach or termination of the provisions of any agreement, instrument, deed or lease to which any Pledgor is a party or by which any Pledgor is bound; or (b) the violation of any law, statute, judgment, decree or governmental order, rule or regulation applicable to any Pledgor. No approval, authorization or other action by, or declaration to or filing with, any governmental or administrative authority or any other Person is required to be obtained or made by any Pledgor in connection with the execution, delivery and performance of this Agreement or the transactions contemplated hereby. 9.
