(b) Within 60 days following the Closing Date, the Buyer (i) shall prepare, or cause to be prepared, financial statements (the "Closing Financial Statements") of the Company and the Company Subsidiaries on a consolidated basis as of the close of business on the Closing Date and for the period from December 31, 2001 through the close of business on the Closing Date on the same basis and applying the same accounting principles, policies and practices that were used in preparing the Financial Statements, including the principles, policies and practices set forth on Schedule 2.5 (determined on a pro forma basis as though the parties had not consummated the transactions contemplated by this Agreement); (ii) shall determine the Net Asset Value as of the Closing Date (the "Closing Net Asset Value") based on the Closing Financial Statements and using the same methodology as was used to prepare the Financial Statements, including the principles, policies and practices set forth on Schedule 2.5; and (iii) shall deliver to the Seller a signed statement that includes the Closing Financial Statements and the Buyer's calculation of the Closing Net Asset Value.

During the Objection Period, the Buyer (1) shall promptly furnish or cause to be furnished to the Seller such work papers and other documents and information relating to the Closing Financial -10-

Statements and the Buyer's calculation of the Closing Net Asset Value as the Seller may request and are available to the Buyer or its agents, including consolidating financial statements, work-in-progress schedules, receivables agings and a schedule of adjustments, and (2) shall promptly respond in reasonable detail to reasonable inquiries by the Buyer with respect to such work papers, documents and information. (d) If, during the Objection Period, the Seller delivers to the Buyer each of the Objection Notice and the Seller's calculation of the Closing Net Asset Value, then the Buyer and the Seller will use reasonable efforts to agree upon the calculation of the Closing Net Asset Value. If the parties fail to agree upon the calculation of the Closing Net Asset Value within 30 days of the Buyer's receipt of the Objection Notice and the Seller's calculation of the Closing Net Asset Value, then the Buyer and the Seller shall submit the matter to PricewaterhouseCoopers in Washington, D.C., certified public accountants (the "Independent Accountants"), for resolution applying the principles, policies and practices set forth in Section 2.5(b).

Immediately following such determination, the Independent Accountants shall provide written notice of their determination that (1) the Buyer's calculation of the Closing Net Asset Value or the Seller's calculation of the Closing Net Asset Value, as the case may be, more closely approximates the Net Asset Value as of the Closing Date based on the principles, policies and practices set forth in Section 2.5(b) and (2) such closer approximation of the Net Asset Value as of the Closing Date shall be deemed to be the Closing Net Asset Value for all purposes of this Agreement, shall be final, binding and conclusive on the parties and shall be used in computing the Adjustment Amount. The sole duty of the Independent Accountants shall be to determine whether the Buyer's calculation of the Closing Net Asset Value or the Seller's calculation of the Closing Net Asset Value more closely approximates the Net Asset Value as of the Closing Date based on the principles, policies and practices set forth in Section 2.5(b) and to provide written notice of such determination to the parties in accordance with this Section 2.5(d). The Buyer and the Seller shall split all the fees and expenses of the Independent Accountants. SECTION 2.6. Escrow Amount.

In the event the Buyer has not exercised such option to reduce the Purchase Price, the Seller further agrees to indemnify and hold the Buyer and its Affiliates harmless for any and all liabilities or obligations, now existing or which may subsequently arise, in connection with the tenant's use, occupancy, possession and/or operation of business under the Hillside lease and in connection with the Seller's obligations under this Section 6.14(b).

(unless the requesting party is entitled to indemnification therefor under Article X). On the Closing Date, the Seller will deliver to the Buyer all documents, books, records (including Tax records), agreements (including all Predecessor Acquisition Agreements), and financial data of any sort relating to the Company and the Company Subsidiaries; provided, however, that the Seller may retain a copy of any such documents, books, records, agreements and financial data.

Upon the transfer of such account balances, the Buyer shall assume responsibility for such account balances and shall indemnify the Seller against all Liability with respect to such account balances, but only to the extent such Liability arises from actions taken by the Buyer after the transfer of such account balances. The Buyer shall waive any limitations with respect to participation requirements applicable to such Company Employees under the applicable provisions of the EMCOR Group, Inc. Welfare Plan other than limitations that are already in effect with respect to such Company Employees and their covered dependents and that have not been satisfied as of the Closing Date under the Reimbursement Account Plans.

The Seller shall be responsible for, and shall indemnify the Buyer against, all expenses and Liability, including attorneys' fees, if applicable, incurred under the WARN Act or any other Law requiring notice prior to termination of employment with respect to any employee who experiences a layoff, employment termination, reduction in hours or other employment related loss prior to the Closing.

contemplated under this Agreement or (ii) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction on or prior to the Closing Date involving any of the Company or the Company Subsidiaries, the other party will cooperate with it and its counsel in the contest or defense, make available their personnel, and provide such testimony and access to their books and records as shall be necessary in connection with the contest or defense, all at the sole cost and expense (including reimbursement for any wages or other out-of-pocket expenses relating to providing such support) of the contesting or defending party (unless the contesting or defending party is entitled to indemnification therefor under Article X). Notwithstanding the provisions of the preceding sentence, to the extent a claim under any Action is within the deductible amount covered by insurance, the other party shall provide such reasonable cooperation as such party would be obliged to provide to an insurance company if such claim exceeded the deductible without any reimbursement obligations by the party contesting or defending such Action so long as such cooperation does not interfere unreasonably with the conduct of such other party's business. SECTION 7.6. Transition. Neither the Buyer nor the Seller will take any action that is designed or intended to have the effect of discouraging any lessor, licensor, customer, supplier, or other business associate of any of the Company and the Company Subsidiaries from maintaining the same business relationships with the Company and the Company Subsidiaries after the Closing as it maintained with the Company and the Company Subsidiaries prior to the Closing.

The Buyer agrees to use its reasonable best efforts to remove, redact, strike through or cover the Comfort Names from any such assets, products or materials before the first anniversary of the Closing Date; provided that Buyer and its Subsidiaries may continue to use the Comfort Names in a -40-

neutral, non-trademark sense to communicate the historical affiliation of the Company Subsidiaries. SECTION 7.11. Vehicle Leases. The Seller at its own expense shall transfer leases for each vehicle currently used by a Company Subsidiary and not leased directly by such Company Subsidiary to such respective Company Subsidiary.

SECTION 7.13. Tax Treatment of the Company.

SECTION 7.14. Surety Bonds. The Buyer shall use commercially reasonable efforts to replace those surety bonds listed on Schedule 7.14 or any replacement bonds thereof for which the Seller is the indemnitor. SECTION 7.15. National Servicing Organization Transition Issues. With respect to Comfort Systems USA National Service Organization, Inc., a Delaware corporation ("NSO"), the parties agree as follows: (a) For a period of one year from the Closing Date, the Seller shall cause the NSO to offer work for its national service account clients ("Clients"), whether such national account clients are currently or hereafter become clients of the NSO, to the Company Subsidiaries in the same manner as such work is currently offered to Subsidiaries of the Seller whether or not such Subsidiaries are Company Subsidiaries. In the case of work for existing Clients, the rates payable by the NSO to the Company Subsidiaries shall be no less favorable to the Company Subsidiaries than those presently offered by the NSO to the Subsidiaries of the Seller for comparable work and the terms of payment shall be commercially reasonable and no less favorable to the Company Subsidiaries than those presently offered by the NSO to third parties for comparable work. In the case of work for new Clients or for different types of work for existing Clients, the rates offered to be paid by the NSO to the Company Subsidiaries and the terms of payment shall be fair and reasonable under the circumstances, and in no event no less favorable to the Company Subsidiaries than those offered from time to time by the NSO to the Subsidiaries of the Seller or to unrelated parties of the Seller. Notwithstanding the foregoing, -41-

nothing contained herein shall require (i) any Company Subsidiary to accept NSO work offered to it by the NSO, (ii) the NSO to accept work assignments from Clients with respect to work assignments on which the NSO reasonably expects to lose money or (iii) the NSO to accept work assignments from any Client which, in the NSO's reasonable judgment, the NSO believes may be unable or unwilling to pay for such work on reasonably commercial terms. The Buyer shall cause each Company Subsidiary offered a work assignment by the NSO to respond promptly to the NSO whether such Company Subsidiary is willing to accept such work assignment. The NSO shall not be required to offer work to any Company Subsidiary where the rate to be received by the NSO from the Client is less than the acceptable hourly rate specified by the Company Subsidiary from time to time. (b) With respect to work that has been or may be undertaken pursuant to contracts or other arrangements between the NSO and Bank One for performance within one year of the Closing Date in the states of Ohio or Indiana or in the greater Detroit, Michigan metropolitan area, the Seller shall cause such work assignments to be offered to Shambaugh & Son L.P. or its direct or indirect subsidiaries (collectively, "S&S") at the rates that have been previously quoted in writing by S&S to the NSO (the "Rates") and on terms of payment that are fair and reasonable under the circumstances. However, the Buyer acknowledges that it has been advised by the Seller that the terms for performing work for Bank One have not yet been agreed to between the NSO and Bank One, and, accordingly, under the circumstances the NSO may request that the Rates be reduced. The NSO shall consult with S&S on, and keep S&S advised on the status of, negotiations between the NSO and Bank One as to rates and related matters. In the case of rates negotiated between Bank One and S&S that would result in a reduction of the Rates, the NSO shall negotiate such proposed reduction in good faith with S&S, and the Buyer shall cause S&S to negotiate such reduction in good faith with the NSO. Nothing herein contained shall require S&S to perform work for Bank One at such reduced rates or require S&S to perform any type of work assignments for Bank One. The Buyer shall cause S&S to respond promptly to the NSO as to whether S&S is willing to accept any work assignment for Bank One offered to it by the NSO. (c) The Buyer and the Seller acknowledge that the Company Subsidiary, American Mechanical, Inc. ("AMC"), and the Seller have, in the past, shared two employees with respect to NSO work, and that from and after the Closing Date such two employees shall be employed solely by AMC. For a period of two years after the Closing Date, the Seller shall not solicit such employees to work for the Seller or any of its Affiliates so long as such employees remain employees of AMC or seek to influence them to leave the employ of AMC. The NSO shall continue to offer work to AMC as provided in subsection (a) hereof. The Seller will make available to AMC any data in the Seller's possession with respect to any customers that originated with AMC and for which AMC currently performs, or within the last three years has performed, work. The Seller shall assign to the Buyer all right, title and interest in the name of "American Mechanical Network" ("AMN") or any variation thereof, the telephone numbers for AMN and the clients of AMN set forth on Schedule 7.15(c) ("AMN Clients"). In the event any AMN Client contacts the Seller or any of its Affiliates for services after the Closing Date, the Seller shall, and shall cause any such Affiliate to, refer such AMN Client to AMC for such requested services. For -42-

The Seller shall maintain insurance policies covering each of the Company Subsidiaries for a period of three years after the Closing Date with respect to professional liability (errors and omissions), contractors' pollution and employment practices on terms and conditions, including coverage and exclusions, substantially similar to those in effect prior to the Closing. Within 30 days after the end of each fiscal year, the Seller shall provide evidence to the Buyer that such policies are in full force and effect. Within 30 days prior to the renewal date of each such insurance policy, the Seller shall provide evidence to the Buyer that such policies have been renewed and shall provide copies of such renewed policies to the Buyer. The Seller agrees to provide copies of any written notices or correspondence that the Seller may receive from each insurance provider, including but not limited to notices or correspondence relating to a failure by the Seller to comply with the applicable terms of the insurance policies or relating to any actual or anticipated changes or modifications to coverage, limits, terms, conditions, exclusions and insureds. In the event the Seller fails to comply with the provisions of this Section 7.16, including but not limited to a failure to renew any insurance policy on or prior to its applicable renewal date, the Seller shall promptly provide written notice of such failure to the Buyer. SECTION 7.17. Bonding Company Reports. The Buyer will cause each Company Subsidiary (i) to prepare and forward to Federal Insurance Company (Chubb) ("Chubb") job status reports, at such intervals as each Company Subsidiary has previously submitted such reports, indicating, in the case of completed contracts, the final contract price and, in the case of uncompleted contracts, the then currently estimated completion date and the then percentage of the contract completed and such other information as Chubb may reasonably request concerning bonded jobs and (ii) with respect to each job as to which a performance bond has been issued by Chubb prior to the Closing Date, upon completion of each such job, to use its best efforts to obtain evidence of substantial completion of each such job from the party with whom such Company Subsidiary contracted and forward such evidence to Chubb.

ARTICLE VIII TAX MATTERS SECTION 8.1. Tax Indemnification. (a) The Seller shall be responsible for, shall pay or cause to be paid, and shall indemnify and hold harmless the Buyer from and against any and all Losses for or in respect of each of the following, without duplication: (i) any and all liability for Taxes of the Company and each of the Company Subsidiaries for all taxable periods (or portions thereof) ending on or before the Closing Date (a "Pre-Closing Tax Period") and with respect to any taxable period that begins on or before and ends after the Closing Date (a "Straddle Period"), for the portion thereof ending on the Closing Date; (ii) all liability (as a result of Treasury Regulation ss. 1.1502-6 or any similar provision of state, local or foreign law or as a transferee or successor by contract or otherwise) imposed on the Company or any of the Company Subsidiaries for the Taxes of the Seller or any other person or entity (other than the Company or any of the Company Subsidiaries) which is or has been an Affiliate of the Company or any of the Company Subsidiaries prior to the Closing Date; (iii) any and all liability for Taxes attributable to the making of Elections (as described under Section 8.9(a)) and any Taxes arising out of any failure by the Seller to pay such Tax; (iv) all Taxes arising out of a breach of any representation or warranty set forth in Section 5.17 other than Section 5.17(b), (v) any payment to be made after the Closing Date under any Tax sharing, Tax indemnity, Tax allocation or similar contract (whether or not written and in each case covering the sharing of income or income-based taxes reported on a combined, unitary or consolidated Tax Return) to which the Company or any of the Company Subsidiaries was obligated or was a party on or prior to the Closing Date, and (vi) all liability for reasonable legal fees and other third-party expenses for any item attributable to any item in clause (i) through (v) above. (b) The Buyer shall be liable for and shall indemnify the Seller for (i) all liability for Taxes of the Company and each of the Company Subsidiaries for any taxable period or portion thereof beginning after the Closing Date and, with respect to a Straddle Period, the portion of such Straddle Period beginning after the Closing Date (the "Post-Closing Tax Period"), (ii) any Taxes to the extent that such Taxes were paid with respect to periods after the Closing by the Seller and not reflected as an asset on the Most Recent Balance Sheet (in which case the amount of such Taxes shall be subject to indemnification when such Taxes would otherwise have become due and payable), (iii) any Taxes attributable to any failure by the Buyer to make any Election and -44-

(iv) all liability for reasonable legal fees and other third-party expenses for any item attributable to any item in clause (i), (ii) or (iii). (c) Payment of any amount due under this Section 8.1 shall be made within thirty days following written notice by the other party that payment of such amounts to the appropriate taxing authority is due. In the case of a Tax that is contested in accordance with the provisions of Section 8.2, payment of Tax to the appropriate taxing authority will not be considered to be due earlier than the date a final determination to such effect is made by the appropriate taxing authority or a court. (d) For purposes of this Section 8.1, whenever it is necessary to determine the liability for Taxes of the Company and the Company Subsidiaries for a portion of a Straddle Period: (i) in the case of any Taxes other than Taxes based upon or related to income or receipts, such Tax shall be deemed to be the amount of such Tax for the entire Taxable period multiplied by a fraction the numerator of which is the number of days during the Straddle Period that are in the Pre-Closing Tax Period or Post-Closing Tax Period, as applicable, and the denominator of which is the number of days in the entire Straddle Period; and (ii) all other Taxes for the Pre-Closing Period or Post-Closing Period, as the case may be, shall be determined by assuming that for purposes of the Pre-Closing Period, the Company and the Company Subsidiaries had a taxable year or period that ended at the close of the Closing Date and for purposes of the Post-Closing Period, the Company and the Company Subsidiaries had a taxable year or period that began at the beginning of the day after the Closing Date. SECTION 8.2. Procedures Relating to Indemnification of Tax Claims. (a) If an audit, investigation or similar proceeding with respect to Tax matters shall be commenced, or a claim shall be made, by any taxing authority, which might result in an indemnity payment pursuant to Section 8.1, the party receiving notice of such audit, investigation, similar proceeding or claim shall promptly notify the other party in writing of such audit, investigation, similar proceeding or claim (a "Tax Proceeding"); provided, however, that failure to give such notice shall not affect the indemnification obligations under Section 8.1 unless such failure materially prejudices the indemnifying party. (b) With respect to any Tax Proceeding which might result in an indemnity payment pursuant to Section 8.1(a), the Seller shall have the right to control all proceedings taken in connection with such Tax Proceeding (including selection of counsel) and, without limiting the foregoing, may with the consent of the other party (which consent shall not be unreasonably withheld) pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any taxing authority with respect thereto, and may, in its reasonable discretion, either pay the Tax claimed and sue for a refund where applicable Law permits such refund suits or contest the Tax Proceeding in any permissible manner. The Buyer shall be entitled to participate -45-

in all proceedings with respect to any such Tax Proceeding (at its expense) and to employ counsel of its choice for such purpose. (c) With respect to any Tax Proceeding which might result in an indemnity payment pursuant to Section 8.1(b), the Buyer shall have the right to control all proceedings taken in connection with such Tax Proceeding (including selection of counsel) and, without limiting the foregoing, may with the consent of the other party (which consent shall not be unreasonably withheld) pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any taxing authority with respect thereto, and may, in its reasonable discretion, either pay the Tax claimed and sue for a refund where applicable Law permits such refund suits or contest the Tax Proceeding in any permissible manner. The Seller shall be entitled to participate in all proceedings with respect to any such Tax Proceeding (at its expense) and to employ counsel of its choice for such purpose. (d) The Seller and the Buyer shall each provide the other (and, in the case of the Buyer, shall cause the Company or Company Subsidiaries, as appropriate, to provide the Seller) with copies of all material documents with respect to the aforementioned Tax Proceedings. Notwithstanding the foregoing, the Buyer and the Seller shall jointly control all proceedings taken in connection with (i) any Tax Proceeding relating solely to Taxes for a Straddle Period and (ii) any Tax Proceeding which might result in both an indemnity payment pursuant to Section 8.1(a) and an indemnity payment pursuant to Section 8.1(b). In no case shall any party settle or otherwise compromise any Tax Proceeding without the other party's prior written consent (which consent may not be unreasonably withheld). (e) The Buyer, the Company and the Company Subsidiaries, on the one hand, and the Seller, on the other hand, shall cooperate with each other in contesting any Tax Proceeding, which cooperation shall include the retention and (upon the other party's request) the provision of records and information which are reasonably relevant to such Tax Proceeding, and making employees available on a mutually convenient basis to provide additional information or explanation of any material provided hereunder or to testify at proceedings relating to such Tax Proceeding and, in the case of the Buyer, causing the Company and the Company Subsidiaries to so cooperate. SECTION 8.3. Adjustment to Purchase Price. The parties agree to treat all payments made under this Article VIII and under any other indemnity provisions contained in this Agreement as adjustments to the Purchase Price for Tax purposes, unless otherwise required by Law. SECTION 8.4. Filing of Tax Returns. (a) Tax Periods Ending on or Before the Closing Date. The Seller shall prepare or cause to be prepared, and the Buyer shall timely file or cause to be timely filed, all Tax Returns (including all amended Tax Returns) that are required to be filed for or with respect to the Company and each Company Subsidiary for all taxable periods ending on or prior to the Closing Date which are filed after the Closing Date other than income Tax Returns with respect to periods for which a consolidated, unitary or combined income Tax Return of the Seller will -46-

include the operations of the Company and the Company Subsidiaries. Such Tax Returns shall be prepared in a manner consistent with prior practice, except to the extent required by GAAP or applicable Law. The Seller will allow the Buyer an opportunity to review and comment upon any such Tax Returns (including any amended returns). The Seller shall reimburse within fifteen days after payment by Buyer or the Company or the Company Subsidiaries of such Taxes. Such Tax Returns shall be prepared in a manner consistent with prior practice except to the extent required by GAAP or applicable Law. (b) Returns for Periods through the Closing Date. The Seller will include the income of the Company and the Company Subsidiaries (including any deferred income triggered into income by Treasury Regulation ss. 1.1502-13 and ss. 1.1502-14 and any income, gain, loss, deduction or other tax item resulting from the Elections (as described in Section 8.9(a)) on the Seller's consolidated unitary, combined or other income Tax Returns for all periods through the Closing Date and pay any income tax attributable to such income. The Buyer shall cause the Company and the Company Subsidiaries to furnish Tax information to the Seller for inclusion in the Seller's consolidated unitary, combined or other income Tax Return for the period which includes the Closing Date in accordance with the past custom and practice of the Company and the Company Subsidiaries. The Seller will allow the Buyer an opportunity to review and comment upon such Tax Returns (including any amended returns) to the extent that they relate to the Company and the Company Subsidiaries. The Seller will take no position on such returns that relate to the Company and the Company Subsidiaries that is inconsistent with prior practice and that would adversely affect the Company and the Company Subsidiaries after the Closing Date. The income of the Company and the Subsidiaries will be apportioned to the period up to and including the Closing Date and the period after the Closing Date by closing the books of the Company and the Company Subsidiaries as of the end of the Closing Date. (c) Tax Periods Beginning Before and Ending After the Closing Date. The Buyer shall prepare or cause to be prepared and file or cause to be filed any Tax Returns for or with respect to the Company and each Company Subsidiary that are required to be filed for Taxable Periods which are Straddle Periods. Such Tax Returns shall be prepared in a manner consistent with prior practice except to the extent required by GAAP or by applicable Law. The Buyer will allow the Seller an opportunity to review and comment upon any such Straddle Period Tax Return (including any amended return). If the Seller objects to the treatment of any item on any such Tax Return or to any amount owed to or by the Seller with respect to any Straddle Period Taxes, the Seller shall, as promptly as practicable, notify the Buyer in writing that it so objects, specifying with particularity any such item and stating the specific factual or legal basis for any such objection. If a notice of objection shall be duly delivered, the Seller and the Buyer shall negotiate in good faith to resolve their disagreement. If the Seller and the Buyer have not resolved their disagreement within five Business Days after receipt by Buyer of such notice, they shall refer the matter for resolution to a mutually acceptable nationally recognized independent accounting firm, the decision of which shall be binding on the Seller and the Buyer. The costs, fees and expenses of the accounting firm shall be borne by (i) the Seller if the net resolution of the disputed items favors the Buyer, (ii) the Buyer if the net resolution of the disputed items favors the Seller and (iii) otherwise equally by the Buyer and the Seller. The Seller shall pay to the Buyer within 15 days after the date on which Taxes are paid with respect to such periods an amount equal to the portion of such Taxes which relates to the Pre-Closing Tax Period, including -47-

any income or gain resulting from the Elections; provided, however, that if the Seller has delivered a notice of objection in respect of any item on the Tax Return or to any amount owed to or by the Seller with respect to any Straddle Period Taxes, and such disagreement is not resolved prior to the filing of the Tax Return, the Seller shall not be required to pay any amount to the Buyer in respect of such disputed item until the dispute has been resolved either by agreement of the parties or by the above-described independent accounting firm. For purposes of this Section 8.4(c), the portion of any such Tax that relates to the Pre-Closing Tax Period shall be determined as prescribed in Section 8.1(d). SECTION 8.5. Cooperation on Tax Matters. The Seller, the Company, the Company Subsidiaries and the Buyer shall reasonably cooperate, and shall cause their respective Affiliates, officers, employees, agents, auditors and other representatives reasonably to cooperate, in preparing and filing all Tax Returns, including providing powers of attorney, maintaining and making available to each other all records necessary in connection with Taxes and in resolving all disputes and audits with respect to all taxable periods relating to Taxes. Such cooperation shall include the retention and (upon the other party's request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Buyer and the Seller agree to retain (and, in the case of the Buyer, to cause the Company and each Company Subsidiary to retain) all books and records with respect to Tax matters pertinent to the Company and the Company Subsidiaries relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by the Buyer or the Seller, any extensions thereof) of the respective taxable periods. SECTION 8.6. Certain Taxes and Fees. All transfer, documentary, sales, use, registration and other such Taxes (including all applicable real estate transfer or gains Taxes) and related fees (including any penalties, interest and additions to Tax) incurred in connection with the transactions contemplated by this Agreement, shall be paid by the Seller when due, and the Seller will, at its own expense, file all necessary Tax Returns and other documentation with respect to all such Taxes, fees and charges, and, if required by applicable law, the Buyer will, and will cause its Affiliates to, join in the execution of any such Tax Returns and other documentation. SECTION 8.7. Carrybacks. The Seller will immediately pay to the Buyer the value of any Tax refund (or reduction in Tax liability) resulting from a carryback of a post-acquisition Tax attribute of any of the Company or the Company Subsidiaries into the Seller's combined or unitary Tax Return, when such refund or reduction is realized by the Seller's group. The Seller will cooperate with the Company and the Company Subsidiaries in obtaining such refunds (or reduction in Tax liability), including through the filing of amended Tax Returns or refund claims. The Buyer agrees to indemnify the Seller for any Taxes resulting from the disallowance of such post-acquisition Tax attribute on audit or otherwise. In computing the value of any Tax refund (or reduction in Tax liability) resulting from a carryback of a post-acquisition Tax attribute of any of the Company or the Company Subsidiaries, the Seller and its Subsidiaries shall be deemed to recognize all other items of gross income, gain, loss, deduction and credit before recognizing any post-acquisition Tax attribute carried back. Notwithstanding the foregoing, the Buyer shall use its best efforts to waive all carryback periods. -48-

SECTION 8.8. Refunds and Credits. Any Tax refund and any amounts credited against Tax that are actually realized by or with respect to the Company or a Company Subsidiary that relate to Tax periods prior to Closing shall be for the account of the Seller, and the Buyer shall pay over to the Seller the net amount of any such refund or credit within thirty days after receipt of such refund or utilization of such credit. SECTION 8.9. Allocation of Purchase Price; Section 338(h)(10) Elections.

The Seller shall reasonably cooperate with the Buyer to take all actions necessary and appropriate (including, timely preparing and filing such additional forms, Tax Returns, elections, schedules and other documents separately or jointly with the Buyer) as may be required to effect and preserve timely Elections in accordance with section 338(h)(10) of the Code, and the regulations promulgated thereunder, and any corresponding provisions of state, local or foreign Tax Law. The Seller, the Buyer, the Company and the Company Subsidiaries shall report the purchase by the Buyer of the Shares in a manner consistent with the Elections and shall take no position inconsistent therewith in any Tax Return or Tax audit or otherwise. (b) To the extent possible, the Buyer, the Seller, the Company and the Company Subsidiaries shall execute at the Closing any and all forms necessary to effectuate the Elections (including IRS Form 8023 and, as applicable, appropriate forms required pursuant to state or local Tax Law) with respect to the purchase and sale of the Shares. In the event, however, any such form or forms are not executed at the Closing, the Buyer, the Seller, the Company and the Company Subsidiaries shall prepare and complete each such form no later than 15 days prior to the date such form is required to be filed. The Buyer, the Seller, the Company and the Company Subsidiaries shall each cause the forms to be duly executed by an authorized person for the Buyer, the Seller, the Company and the Company Subsidiaries in each case, and shall duly and timely file the forms in accordance with applicable tax laws and the terms of this Agreement.

Such Allocations shall be set forth on a schedule to be prepared jointly by the Buyer and the Seller within 135 days of the Closing. If during such period the Buyer and the Seller cannot agree on such Allocations, such dispute shall be submitted to a mutually acceptable nationally recognized accounting firm. If an Allocation is submitted to such accounting firm, it shall be adjusted to reflect all agreed upon changes and the resolution of -49-

all disputed items by the accounting firm (such allocation as adjusted either as a result of negotiation between the parties or as a result of the accounting firm's decision). The Buyer, the Seller and the Company Subsidiaries (A) shall be bound by, (B) shall file all Tax Returns on a basis consistent with, and (C) shall take no position in any Tax Return or Tax audit or otherwise which is inconsistent with the Allocations.

or warranty shall be deemed to occur if there would have been a breach of such representation or warranty absent such qualification; (ii) the breach, or default in the performance by the Seller, of any covenant, agreement or obligation to be performed by the Seller pursuant to this Agreement or the Transition Services Agreement; (iii) any Losses resulting from any third party claims or Actions or any other conditions (including, but not limited to, taxes, environmental conditions, litigation, product and service warranty and liability matters and employment-related matters) to the extent such Losses relate to an act, event or condition occurring or existing at or prior to the Closing Date; provided, however, that any Liability that is covered by the Purchase Price adjustment provisions of Section 2.5 shall not give rise to any indemnification obligation under this Section 10.2(a)(iii) to the extent such Liability is covered by the adjustment provisions of Section 2.5; provided, further, that indemnification rights under this Section 10.2(a)(iii) shall survive the Closing for a period of two years beginning on the Closing Date, but not longer, except with respect to indemnification rights for any third party claims or Actions or environmental conditions which shall survive indefinitely; (iv) any Losses resulting from violations of plumbing licensing requirements; (v) (A) any Losses in connection with any Company Plan that is not a Transferred Company Plan, (B) any Losses in connection with a Transferred Company Plan to the extent such Losses arise from an act, event or condition occurring or existing at or prior to the Closing Date, except for employment agreements with respect to which Losses arise from an act, event or condition occurring after the Closing Date (C) any Losses resulting from the failure to file GUST amendments that were required to be filed on or before February 28, 2002 and (D) any Losses resulting from the participation in employment benefit plans pursuant to a collective bargaining agreement or any other agreement with any labor union or association by employees who are not members of any labor union, association or other representative of employees during periods at or prior to the Closing Date; (vi) any Losses (A) resulting from third party claims or Actions that would have been covered by any type of insurance to the extent such claim or Action is not covered as a result of denials of coverage or inadequate insurance coverage, (B) resulting from deductibles, retrospectively rated insurance policies, self-insured retentions, risk-retention groups or other similar arrangements or (C) resulting from claims incurred on or prior to the Closing Date (whether or not reported) by Company Employees and not paid on or prior to the Closing Date with respect to any life insurance, health, medical, dental, disability or other similar welfare plan, agreement, program, policy or other arrangement; -54-

(vii) any Losses resulting from the failure to hold a sufficient, valid and enforceable license to use any Intellectual Property used in the business of any Company Subsidiary as currently conducted or that has been used in such business at any time prior to the Closing, including but not limited to any remediation costs, which, to the extent that is commercially reasonable, shall be the cost of obtaining a license of the currently available version of such Intellectual Property; and (viii) any Losses relating to the failure to collect in the aggregate the full amount of the Receivables outstanding as of the Closing Date (other than the Scheduled Amounts) (net of the allowance for doubtful accounts set forth on the Most Recent Balance Sheet) within 14 months after the Closing Date (provided that each Company Subsidiary has used its commercially reasonable efforts to collect such Receivables). Notwithstanding the foregoing, the first parenthetical to this subparagraph (viii) shall not apply to any amount set forth on Schedule 5.19(a) to the extent (A) such amount has been included as accounts receivable in the calculation of assets for determining Closing Net Asset Value and (B) there has not been included as billings in excess of costs in respect of such amount an equal or greater number in the calculation of liabilities for determining Closing Net Asset Value. (b) Promptly after receipt by a Buyer Indemnified Party of notice of the commencement of an Action or other event giving rise to a Buyer Claim with respect to which such Buyer Indemnified Party is entitled to indemnification under this Section 10.2, such Buyer Indemnified Party shall notify (the "Buyer Claim Notice") the Seller in writing of the commencement of such Action or the assertion of such Buyer Claim; provided, however, that if such Buyer Claim Notice is given within the period prescribed in Section 10.1, then the failure to give such Buyer Claim Notice promptly shall not affect the right to indemnification hereunder except to the extent of actual prejudice to the Seller. The Seller shall have the option, and shall notify such Buyer Indemnified Party in writing within 20 Business Days after the date of the Buyer Claim Notice of its election, either (i) to participate (at the expense of the Seller) in the defense of such Action or Buyer Claim (in which case the defense of such Action or Buyer Claim shall be controlled by such Buyer Indemnified Party) or (ii) to take charge of and control the defense of such Action or Buyer Claim (at the expense of the Seller) with counsel reasonably acceptable to such Buyer Indemnified Party; provided, however, that the Seller shall not be entitled to control any Buyer Claim already covered by insurance or relating to construction, warranty or service disputes, except for a contractual dispute with a customer with whom a Company Subsidiary does not have a material ongoing relationship. Any such construction, warranty or service disputes shall be handled by the Buyer and its counsel at the expense of the Seller; provided, however, that the Buyer and its counsel shall act in a manner consistent with a duty to protect the Seller's interests as if they were the Buyer's own interests and shall keep the Seller reasonably informed of the status of any such disputes. If the Seller fails to notify such Buyer Indemnified Party of its election within the applicable response period, then the Seller shall be deemed to have elected not to control the defense of such Action or Buyer Claim. If the Seller elects to assume the defense of such Action or Buyer Claim, the Buyer Indemnified Party shall have the right to employ separate counsel and participate in the defense of such Action or Buyer Claim, but the fees and expenses of such counsel shall be at the expense of such Buyer -55-

Indemnified Party unless (A) the named parties in such Action or Buyer Claim (including any impleaded parties) include both such Buyer Indemnified Party and the Seller, and such Buyer Indemnified Party shall have been reasonably advised by such counsel that there may be one or more legal defenses available to it that are different from or additional to those available to the Seller, (B) such Buyer Indemnified Party has been reasonably advised by counsel that representation by the Seller is inappropriate in light of an actual or potential conflict of interest between them, or (C) such Buyer Indemnified Party has reasonably determined that Losses that may be incurred may exceed either individually, or when aggregated with other Buyer Claims, the Maximum Indemnity Amount (in which case, the Seller shall not have the right to control the defense of such Action or Buyer Claim on behalf of such Buyer Indemnified Party, it being understood, however, that the Seller shall not, in connection with such Action or Buyer Claim, be liable for the fees and expenses of more than one such separate firm of attorneys (in addition to any local counsel) and that all such fees and expenses shall be reimbursed as they are incurred). (c) If the Seller does not control the defense of any Action or Buyer Claim, then the Buyer Indemnified Party may settle such Action or Buyer Claim only with the written consent of the Seller (not to be unreasonably withheld or delayed). If the Seller elects to control the defense of any Action or Buyer Claim, then it will not consent to the entry of judgment or compromise or settle such Action or Buyer Claim without the consent of the Buyer Indemnified Party (not to be unreasonably withheld or delayed). SECTION 10.3. Indemnification by Buyer. (a) Subject to the limitations set forth in Sections 10.1 and 10.4, the Buyer hereby agrees to indemnify and hold the Seller and its directors, officers, employees, stockholders and Affiliates (collectively, the "Seller Indemnified Parties") harmless from and against any and all Losses imposed upon or incurred by the Seller Indemnified Parties (any of such Losses by Seller Indemnified Parties, a "Seller Claim") as a result of or in connection with any of the following: (i) any inaccuracy or breach of a representation or warranty as of the date hereof or as of the Closing Date made by the Buyer in this Agreement or in any certificate delivered pursuant hereto; provided that for purposes of this provision, with respect to any representation or warranty that is qualified by materiality, Material Adverse Effect or knowledge, a breach of such representation or warranty shall be deemed to occur if there would have been a breach of such representation or warranty absent such qualification; and (ii) the breach of, or default in the performance by the Buyer, of any covenant, agreement or obligation to be performed by the Buyer pursuant to this Agreement or the Transition Services Agreement; (iii) any Losses resulting from the Seller's obligations to indemnify any surety company in respect of claims made by reason of the acts or omissions of a Company Subsidiary to the extent such act or omission solely relates to an act, event or condition occurring after the Closing Date; and -56-

(iv) the guarantees of the Seller listed on Schedule 10.3(a)(iv) to the extent each such Loss relates to an act, event or condition occurring after the Closing Date. (b) Promptly after receipt by a Seller Indemnified Party of notice of the commencement of an Action or other event giving rise to a Seller Claim with respect to which the Seller Indemnified Party is entitled to indemnification under this Section 10.3, such Seller Indemnified Party receiving such notice shall notify (the "Seller Claim Notice") the Buyer in writing of the commencement of such Action or the assertion of such Seller Claim; provided, however, that if such Seller Claim Notice is given within the period prescribed in Section 10.1, then the failure to give such Seller Claim Notice promptly shall not affect the right to indemnification hereunder except to the extent of actual prejudice to the Buyer. The Buyer shall have the option, and shall notify such Seller Indemnified Party in writing within 20 Business Days after the date of the Seller Claim Notice of its election, either (i) to participate (at the expense of the Buyer) in the defense of the Action or Seller Claim (in which case the defense of such Action or Seller Claim shall be controlled by such Seller Indemnified Party) or (ii) to take charge of and control defense of such Action or Seller Claim (at the expense of the Buyer) with counsel reasonably acceptable to such Seller Indemnified Party. If the Buyer fails to notify such Seller Indemnified Party of its election within the applicable response period, then the Buyer shall be deemed to have elected not to control the defense of such Action or Seller Claim. If the Buyer elects to assume the defense of such Action or Seller Claim, such Seller Indemnified Party shall have the right to employ separate counsel and participate in the defense of any such Action or Seller Claim, but the fees and expenses of such counsel shall be at the expense of such Seller Indemnified Party unless (A) the named parties in such Action or Seller Claim (including any impleaded parties) include both such Seller Indemnified Party and the Buyer, and such Seller Indemnified Party shall have been reasonably advised by such counsel that there may be one or more legal defenses available to it that are different from or additional to those available to the Buyer, (B) the Seller Indemnified Party has been reasonably advised by counsel that representation by the Buyer is inappropriate in light of an actual or potential conflict of interest between them, or (C) such Seller Indemnified Party has reasonably determined that Losses that may be incurred may exceed either individually, or when aggregated with other Seller Claims, the Maximum Indemnity Amount (in which case, the Buyer shall not have the right to assume the defense of such Action or Seller Claim on behalf of such Seller Indemnified Party, it being understood, however, that the Buyer shall not, in connection with such Action or Seller Claim be liable for the fees and expenses of more than one such separate firm of attorneys (in addition to any local counsel) and that such fees and expenses shall be reimbursed as they are incurred). (c) If the Buyer does not control the defense of any Action or Seller Claim, then the Seller Indemnified Party may settle such Action or Seller Claim only with the written consent of Buyer (not to be unreasonably withheld or delayed). If the Buyer elects to control the defense of any Action or Seller Claim, then it will not consent to the entry of judgment or compromise or settle such Action or Seller Claim without the consent of the Seller Indemnified Party (not to be unreasonably withheld or delayed). SECTION 10.4. Limitation of Liability. Notwithstanding the foregoing, (a) the Seller shall not be obligated to indemnify the Buyer Indemnified Parties pursuant to Section -57-

10.2(a)(i) or 10.2(a)(iii), and Buyer shall not be obligated to indemnify the Seller Indemnified Parties pursuant to Section 10.3(a)(i), in each case, unless and until (i) except as otherwise set forth in clause (ii) below, the amount of all Losses incurred by the Buyer Indemnified Parties, or by the Seller Indemnified Parties, as the case may be, exceeds $1,000,000 in the aggregate (the "Basket"), in which event the party seeking indemnity may recover all Losses incurred in excess of the Basket from the first dollar above the Basket, and (ii) with respect only to Losses incurred by any Buyer Indemnified Party in connection with a breach of the representations and warranties set forth in Section 5.19(a) or the related indemnification set forth in Section 10.3(a)(viii), the amount of such Losses exceeds $1,000,000 in the aggregate (the "Receivables Basket"), such Receivables Basket not to be aggregated with the Basket, in which event the Buyer Indemnified Party may recover all Losses incurred in excess of the Receivables Basket from the first dollar above the Receivables Basket, subject to Section 10.5, and the Seller acknowledges and agrees that any accounts receivable not collected within 14 months of its creation shall be deemed "uncollectible" for purposes of the indemnification provisions of this Agreement; and (b) the Seller's maximum liability for Losses under Sections 10.2(a)(i) and 10.2(a)(iii) and Buyer's maximum liability for Losses under Section 10.3(a)(i) shall be, in each case, an amount equal to the Purchase Price (the "Maximum Indemnity Amount"). The parties hereto acknowledge and agree that this Section 10.4 shall not apply to indemnification obligations of the Seller pursuant to Section 8.1(a), 10.2(a)(ii), 10.2(a)(iv), 10.2(a)(v), 10.2(a)(vi) or 10(a)(vii) hereof, or the indemnification obligations of the Buyer pursuant to Section 8.1(b), 10.3(a)(ii), 10.3(a)(iii) or 10.3(a)(iv), each of which shall be without deduction or limitation. SECTION 10.5. Certain Indemnification Matters With Respect to Receivables. (a) The Buyer agrees to provide updates for the periods ended September 30, 2002 and April 30, 2003, within 45 days after each such period, as to (i) the aggregate amount of the Receivables which have not been collected, (ii) the status of each unpaid Receivable in excess of $50,000 and (iii) to the Buyer's best knowledge, the creditworthiness of any account debtor owing any such unpaid Receivable in excess of $50,000; provided, however, that any failure by the Buyer to deliver such updates in a timely manner shall not affect the Buyer's right to indemnification for Receivables under this Article X except to the extent of actual prejudice to the Seller. (b) With respect to the indemnification provisions of Section 10.2(a)(viii) and Section 10.4(a)(ii), the parties agree as follows: (i) to the extent a Buyer Indemnified Party collects Receivables that had been written off by the Seller prior to the Closing Date, such Buyer Indemnified Party shall credit such Receivables against any indemnification amounts owed by the Seller to the Buyer Indemnified Parties; (ii) to the extent a Buyer Indemnified Party receives payment in respect of indemnification for Receivables, such Buyer Indemnified Party shall assign to the Seller all rights to such Receivables, as well as any associated liens; and -58-

(iii) to the extent a Buyer Indemnified Party collects Receivables for which the Seller has previously indemnified such Buyer Indemnified Party, such Buyer Indemnified Party shall remit such proceeds to the Seller. SECTION 10.6. Exclusive Remedy. After the Closing, the parties' sole and exclusive recourse against each other for any Loss or claim of Losses arising out of or relating to any breach of any representation, warranty or covenant in this Agreement, except for any claim of fraud, shall be expressly limited to the provisions of this Article X and Sections 8.1(a) and 8.1(b). The Seller shall not have any right of contribution from the Company or any Company Subsidiary with respect to any Loss claimed by the Buyer. The Seller hereby agrees that it will not make any claim for indemnification against any of the Company or the Company Subsidiaries by reason of the fact that it was a director, officer, employee, or agent of any such entity or was serving at the request of any such entity as a partner, trustee, director, officer, employee, or agent of another entity (whether such claim is for judgments, damages, penalties, fines, costs, amounts paid in settlement, losses, expenses, or otherwise and whether such claim is pursuant to any statute, charter document, bylaw, agreement, or otherwise) with respect to any action, suit, proceeding, complaint, claim, or demand brought by the Buyer against the Seller (whether such action, suit, proceeding, complaint, claim, or demand is pursuant to this Agreement, applicable law, or otherwise). ARTICLE XI TERMINATION SECTION 11.1. Termination. This Agreement may be terminated and the transactions contemplated by this Agreement may be abandoned at any time, prior to the Closing, only as follows: (a) by mutual written consent of the Buyer and the Seller at any time prior to the Closing; (b) by the Buyer, upon written notice to the Seller at any time prior to the Closing, in the event that the Seller has breached any representation, warranty, or covenant contained in this Agreement that would cause the provisions of Section 9.2 not to be satisfied, the Buyer has notified the Seller of the breach, and the breach has continued without cure for a period of 30 days after the notice of breach; (c) by the Seller, upon written notice to the Buyer at any time prior to the Closing, in the event that the Buyer has breached any representation, warranty, or covenant contained in this Agreement that would cause the provisions of Section 9.3 not to be satisfied, the Seller has notified the Buyer of the breach, and the breach has continued without cure for a period of 30 days after the notice of breach; (d) by the Buyer or the Seller, upon written notice to the other party at any time prior to the Closing, if the Closing Date shall not have occurred on or before June 30, 2002; -59-

provided, however, that the right to terminate this Agreement under this Section 11.1(d) shall not be available to any party whose breach of any obligation under this Agreement has been the cause of, or has resulted in, the failure of the Closing Date to occur on or before such date; (e) by the Buyer or the Seller, upon written notice to the other party at any time prior to the Closing, if any court of competent jurisdiction in the United States or any other Governmental Authority in the United States shall have issued an order, decree or ruling or taken any other action restraining, enjoining or otherwise prohibiting the transactions contemplated hereby and such order, decree, ruling or other action shall have become final and nonappealable; provided, however, that the right to terminate this Agreement under this Section 11.1(e) shall not be available to any party whose breach of any obligation under this Agreement has been the cause of, or has resulted in, such order, decree, ruling or other action; or (f) by the Buyer, in the event that the Seller fails to satisfy the requirements of Section 6.10 by April 1, 2002; provided that, in the event the Seller fails to satisfy the requirements of Section 6.10 by April 1, 2002, and this Agreement is not terminated under this Section 11.1(f), the parties agree that the Target Net Asset Value shall be increased by an amount equal to the consolidated earnings of the Company and the Company Subsidiaries for the period from March 1, 2002 through the Closing Date. SECTION 11.2. Effect of Termination. If this Agreement is terminated pursuant to Section 11.1(a), (e) or (f) and the transactions contemplated by this Agreement are not consummated, all rights and obligations of the parties under or pursuant to this Agreement shall terminate without further liability of either party to the other; provided, however, the obligations contained in this Section 11.2, the publicity provisions contained in Section 6.5, the confidentiality provisions contained in Section 6.6, and the expenses provision contained in Section 12.2 of this Agreement shall survive any such termination; provided, further, that no termination shall relieve any party from liability for any breach of this Agreement. ARTICLE XII MISCELLANEOUS SECTION 12.1. Entire Agreement. Except as set forth in Section 6.6 hereof, this Agreement and the schedules and exhibits hereto and the documents referred to herein and to be delivered pursuant hereto constitute the entire agreement between the parties pertaining to the subject matter hereof, and supersede all prior and contemporaneous agreements, understandings, negotiations and discussions of the parties, whether oral or written, with respect to the subject matter hereof, and there are no warranties, representations or other agreements between the parties in connection with the subject matter hereof, except as specifically set forth herein or therein; provided, however, that the Confidentiality Agreement between the parties shall survive execution and delivery of this Agreement.

WITNESSETH: WHEREAS, the Seller and the Buyer are parties to a Purchase Agreement, dated as of February 11, 2002 (the "Purchase Agreement"); and WHEREAS, pursuant to Sections 2.2 and 2.6 of the Purchase Agreement, the Buyer and the Seller have agreed to deposit $2,500,000 (together with all interest and profits thereon and proceeds therefrom, the "Adjustment Escrow Amount") in an escrow account to be held in escrow during the period commencing on the Closing Date (as defined below) and expiring on the date on which payment of the Adjustment Amount (as defined below) is made in accordance with Sections 2.4 and 2.5 of the Purchase Agreement (such period, the "Adjustment Security Period"); and WHEREAS, pursuant to Sections 2.2 and 2.6 of the Purchase Agreement, the Buyer and the Seller have agreed to deposit $5,000,000 (together with all interest and profits thereon and proceeds therefrom, the "Indemnification Escrow Amount") in an escrow account to be held in escrow during the period commencing on the Closing Date and expiring 18 months after the Closing Date (such period, the "Indemnification Security Period"); and WHEREAS, the Agent is willing to act as escrow agent hereunder; NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereto hereby agree as follows: 1.

EXHIBIT B TRANSITION SERVICES AGREEMENT This Transition Services Agreement (this "Services Agreement") is made as of March [__], 2002, by and between Comfort Systems USA, Inc., a Delaware corporation ("Seller"), and EMCOR-CSI Holding Co., a Delaware corporation ("Buyer"). Pursuant to a Purchase Agreement dated as of February 11, 2002 (the "Purchase Agreement") between Seller and Buyer, Buyer directly acquired all the Interests (as defined below) in the Company (as defined below) and indirectly acquired all the outstanding capital stock of and ownership interests in the Company Subsidiaries (as defined below) on the terms set forth therein. Prior to the Closing (as defined below), the Company and the Company Subsidiaries received certain services from Seller, and Seller received certain services from the Company and the Company Subsidiaries. Seller and Buyer desire that these services continue to be provided to or by the Company and the Company Subsidiaries after the Closing upon the terms and conditions set forth in this Services Agreement. In consideration of the mutual covenants and agreements contained in this Services Agreement, the parties hereby agree as follows: ARTICLE 1 DEFINITIONS 1.1 Definitions Incorporated. All capitalized terms not otherwise defined in this Services Agreement have the meaning ascribed to them in the Purchase Agreement. 1.2 Additional Definitions. Unless the context otherwise requires, the following terms, and their singular or plural, used in this Services Agreement shall have the meanings set forth below: (a) "Buyer" shall have the meaning set forth in the preamble hereto.

(k) "Services" shall mean, collectively, the Buyer Provided Services and the Seller Provided Services. (l) "Services Agreement" shall have the meaning set forth in the preamble hereto. (m) "Term" shall have the meaning set forth in Section 4.1. ARTICLE 2 SERVICES 2.1 Seller Provided Services. Pursuant to the terms of this Services Agreement, Seller will provide, or cause to be provided, to Buyer for the Company and the Company Subsidiaries the services described on Schedule 2.1(A) hereto and Schedule 2.1(B) hereto (individually or in the aggregate, the "Seller Provided Services"). 2.2 Buyer Provided Services. Pursuant to the terms of this Services Agreement, Buyer will provide, or cause to be provided, to Seller the services described on Schedule 2.2 hereto (individually or in the aggregate, the "Buyer Provided Services"). 2.3 Other Services. If, after the execution of this Services Agreement, (a) the parties determine that (i) a service provided by Seller to the Company or any Company Subsidiary or (ii) a service provided by the Company or any Company Subsidiary to Seller, in each case in accordance with the practice of Seller, the Company or such Company Subsidiary, as applicable, prior to the Closing, was inadvertently omitted from the Schedules hereto, and (b) Buyer or Seller, as the case may be, desires to temporarily continue receiving such service, then the parties shall negotiate in good faith to attempt to agree to the terms and conditions upon which such service shall be added to this Services Agreement, it being agreed that the charges for such service should be determined on a basis consistent with the methodology for determining the initial compensation for the Services described on the Schedules hereto. ARTICLE 3 COMPENSATION 3.1 Compensation for Services. Subject to Section 3.3, the compensation for any Service for the duration of the Term shall be as specified on the Schedules hereto. 2

3.2 Cost of Consents. Unless otherwise specified on the Schedules hereto, in the case of software applications and other intellectual property that are provided by Seller to, are owned by, or are licensed to, the Company or any Company Subsidiary, (a) Seller shall bear all costs and expenses of obtaining any and all consents, waivers and licenses which may be necessary in connection with Seller's providing software Services to Buyer for the Company and the Company Subsidiaries; and (b) Buyer and Seller shall cooperate in good faith to minimize the costs and expenses to be incurred by Seller pursuant to this Section 3.2. 3.3 Terms of Payment; Dispute Resolution. (a) Except as otherwise expressly provided herein or on the Schedules hereto, each Provider shall invoice the applicable Recipient monthly (or, if mutually agreeable to such Provider and such Recipient, quarterly or semi-annually) for the Services provided by such Provider under this Services Agreement. Payment in United States dollars shall be made by the applicable Recipient within 15 days after receipt of invoice. No Recipient shall withhold or set-off any payments to any Provider under this Services Agreement, and no Provider shall withhold the provision of any Services to any Recipient, notwithstanding any dispute that may be pending between them, whether under this Services Agreement or otherwise (any required adjustment being made on subsequent invoices), unless such withholding is provided for in a judgment by a court of competent jurisdiction in accordance with Section 7.7. (b) If there is a dispute between any Recipient and any Provider regarding the amounts shown as billed to such Recipient on any invoice from such Provider, such Provider shall furnish to such Recipient reasonable documentation to substantiate the amounts so billed including, but not limited to, listings of the dates, times and amounts of the Services in question, if applicable and practicable. Upon delivery of such documentation, such Recipient and such Provider shall cooperate and each use its reasonable best efforts to resolve such dispute between themselves. If (i) such Recipient and such Provider are unable to resolve their dispute within 30 calendar days of the initiation of such procedure, (ii) such Recipient believes in good faith and with a reasonable basis that the amounts shown as billed to such Recipient are inaccurate or are otherwise not in accordance with the terms of this Services Agreement and (iii) such Recipient has previously paid such invoice in accordance with Section 3.3(a), then such Recipient shall have the right, at its own expense, to commence litigation in accordance with Section 7.7. ARTICLE 4 TERM 4.1 Term. Except as expressly otherwise provided in this Services Agreement, (a) the term with respect to any particular individual Service shall be as indicated on the applicable Schedule hereto and (b) the term of this Services Agreement (the "Term") shall end on the date on which the respective separate terms for all Services as indicated on the Schedules hereto shall have expired. The obligation of any Recipient to make a payment for Services previously 3

rendered shall not be affected by the expiration of the Term and shall continue until full payment is made. 4.2 Termination of Individual Services. Each individual Service has a separate term as provided in Schedule 2.1(A), Schedule 2.1(B) or Schedule 2.2, as applicable, which term may, in the case of Services listed on Schedule 2.1(A) and Schedule 2.2, include a right of extension as described in such Schedule. Unless earlier terminated pursuant to the immediately succeeding sentence, the obligation of a Provider to provide any applicable Service will terminate upon the expiration of the separate term for such Service as provided in the applicable Schedule. At any time during the Term, a Recipient may terminate any individual Service provided to such Recipient under this Services Agreement on a Service-by-Service basis (and/or a location-by-location basis, where an individual Service is provided to multiple locations of a Recipient) upon written notice to the Provider identifying (a) the particular Service (or location) to be terminated and (b) the effective date of termination, which date shall not be less than three Business Days after receipt of such notice unless the applicable Provider otherwise agrees. ARTICLE 5 CERTAIN COVENANTS 5.1 Points of Contact. Each Provider and Recipient shall name a point of contact, which shall be added to the Schedules hereto, and which may be amended from time to time upon prior written notice to the other party. Such points of contact shall be responsible for the implementation of this Services Agreement between such Provider and such Recipient, including resolution of any issues that may arise during the performance of such Provider and such Recipient hereunder on a day-to-day basis. Issues that cannot be resolved by the respective points of contact will be escalated through the respective parties' management. 5.2 Cooperation; Reasonable Care. (a) The parties will cooperate (using reasonable best efforts) to effect a smooth and orderly transition of each Service provided hereunder from the applicable Provider to the applicable Recipient; provided, however, that this Section 5.2 shall not require any party hereto to incur any out-of-pocket expenses unless and except as expressly otherwise provided herein. The parties will cooperate in good faith toward completing the transition of the Services provided hereunder prior to the expiration of their respective terms. (b) Each Provider shall (i) perform the Services that it is required to provide to the applicable Recipient under this Services Agreement with reasonable skill and care and (ii) use at least that degree of skill and care that it would exercise in similar circumstances in carrying out its own business. Each Provider shall take necessary measures to protect the applicable Recipient's data that is processed by such Provider from destruction, deletion or unauthorized change; provided, however, that a Provider shall be deemed to have satisfied this obligation if the measures taken to protect and recover the Recipient's data are equivalent to what it uses in carrying out its own business. 4

5.3 Migration Projects. Each Provider will provide the applicable Recipient with reasonable support necessary to transition the Services that such Provider is required to provide to such Recipient under this Services Agreement, which may include providing reasonable access to data and other information and to such Provider's employees; provided, however, that such activities shall not unduly burden or interfere with such Provider's business and operations. Illustrations of migration services are costs of transferring documentation (including procedures and manuals), removing data from the Provider's systems and records for access by the Recipient and responding to inquiries associated with software mapping. Each party shall bear the costs that it incurs in effecting the migration of such Services. 5.4 Further Assurances. From time to time after the date hereof, without further consideration, each party shall, upon the reasonable written request of the other party, execute and deliver such formal lease or license agreements or any other documentation which may be required to further the intents and purposes of this Services Agreement with respect to any lease or license provided for herein or contemplated hereby. ARTICLE 6 INDEMNITIES AND WARRANTIES 6.1 Indemnity. (a) Each party will indemnify and hold harmless the other party and the officers, directors, agents, employees and invitees of such other party, against all liabilities, claims, losses, damages, death or personal injury of whatever nature or kind, arising out of such party's performance of this Services Agreement or the entry of such party's agents, employees or invitees in the premises of the other party, to the extent occasioned by such party's own willful misconduct or negligent actions or omissions or the willful misconduct or negligent actions or omissions of the agents, employees or invitees of such party. (b) Seller shall indemnify and hold harmless Buyer and its Related Parties from and against any and all liabilities, claims, losses or damages arising from or relating to any intellectual property infringement, including, but not limited to, such claims based upon Seller's infringement or misuse of trademarks, copyrights, trade secrets, patents or other proprietary rights, arising out of Seller's performance of the Seller Provided Services. 6.2 Warranties. (a) Each Provider warrants that each Service provided hereunder by such Provider or its Subsidiaries shall be performed at an equivalent level of quality in respect of such Service to that provided by such Provider or its Subsidiaries, as the case may be, prior to the execution date of this Services Agreement. THERE ARE NO OTHER WARRANTIES OR REPRESENTATIONS WITH RESPECT TO THE PROVISION OF SERVICES PROVIDED HEREUNDER, WHETHER EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. 5

(b) Each Provider shall (i) pass through to the applicable Recipient the benefits of any express warranties received from third parties relating to any Service provided by such Provider to such Recipient and (ii) assist such Recipient with any warranty claim related to such Service. ARTICLE 7 MISCELLANEOUS 7.1 Resolution of Disputes; Continuation of Services Pending Outcome of Dispute. In the event of any dispute between the parties, the parties agree to be bound by the litigation procedures set forth in Section 7.7. Unless otherwise specified in the Schedules hereto, notwithstanding the existence of any dispute between the parties, no Provider shall withhold the provision of any Service to any Recipient under this Services Agreement, unless so provided in a judicial determination that such Recipient is in default of a material obligation under this Services Agreement. 7.2 Independent Contractor. In providing Services hereunder, each Provider and each of its Subsidiaries shall act solely as an independent contractor. Nothing herein shall constitute or be construed to be or create a partnership, joint venture or principal/agent relationship between Buyer or any of its Related Parties, on the one hand, and Seller or any of its Related Parties, on the other. 7.3 Notices. Other than the routine administrative actions in furtherance of the Services to be provided hereunder, all notices, consents, waivers, claims and other communications hereunder (each a "Notice") shall be in writing and shall be (a) personally delivered, (b) deposited, prepaid in a nationally established overnight delivery firm such as Federal Express, (c) mailed by certified mail, return receipt requested, or (d) transmitted by facsimile as follows: If to Seller: Comfort Systems USA, Inc. 777 Post Oak Boulevard Suite 500 Houston, Texas 77056 Attn: General Counsel Fax No.: (713) 830-9659 If to Buyer: EMCOR-CSI Holding, Co. c/o EMCOR Group, Inc. 101 Merritt Seven, 7th Floor Norwalk, Connecticut 06851 Attn: Sheldon I.

In any such suit, action or proceeding, each party waives, to the fullest extent it may effectively do so, personal service of any summons, complaint or other 7

process and agrees that the service thereof may be made by certified or registered mail, addressed to such party at its address set forth in Section 7.3.

The signature of any party to one counterpart shall be deemed to be a signature to and may be appended to any other counterpart. 7.9 Assignment. This Services Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns; provided, however, that this Services Agreement may not be assigned by either party to any Person without the prior written consent of the other party, which consent shall not be unreasonably withheld or delayed.

EXHBIT 99.1 [COMFORT SYSTEMS LOGO] - -------------------------------------------------------------------------------- CONTACT: Gordon Beittenmiller Chief Financial Officer (713) 830-9600 FOR IMMEDIATE RELEASE COMFORT SYSTEMS USA TO DIVEST OPERATIONS, STRENGTHEN BALANCE SHEET --- ANNOUNCES PRELIMINARY FOURTH QUARTER INFORMATION --- HOUSTON, TX - FEBRUARY 12, 2002 - COMFORT SYSTEMS USA, INC. (NYSE: FIX), a leading provider of commercial/industrial heating, ventilation and air conditioning ("HVAC") services, today announced that it has signed a definitive agreement to sell 19 of its operations to EMCOR Group, Inc. (NYSE: EME) ("EMCOR") for $186.25 million. The Company expects that net of taxes, transaction costs, and escrows, approximately $160 million of this amount will be used to reduce debt and substantially strengthen the Company's balance sheet. The transaction, which is subject to regulatory approval, is expected to close in the first quarter of 2002. The 19 operations being divested posted 2001 revenues of approximately $650 million and are predominantly located in the Midwest and in the New York metropolitan area. Included in the divestiture is the Company's largest current operating unit, Shambaugh and Son, based in Fort Wayne, Indiana, with 2001 revenues of approximately $247 million. Bill Murdy, Comfort Systems USA's Chairman and CEO, said, "This step will greatly improve Comfort Systems USA's balance sheet and significantly enhance our operating and financial flexibility. Our core strategies remain unchanged: a strong foundation of premier commercial HVAC operations together with growth initiatives in multi-location service, energy efficiency, and building automation. Our service, energy and automation initiatives can now take an even greater role in our operating profile, with added protection to our financial position during a time of continuing near-term economic uncertainty in our industry."

To provide a more complete picture of Comfort Systems USA in connection with this transaction, the Company also released preliminary unaudited information regarding fourth quarter and full year 2001 results. This information excludes any impairment to goodwill or other long-lived assets that may be associated with the EMCOR transaction. The Company expects to report fourth quarter revenues of $370 million to $380 million, and earnings before interest, taxes, depreciation and amortization ("EBITDA") of $15.5 million to $18.5 million. Net income for the fourth quarter is expected to be $1.6 million to $3.4 million, and earnings per share are expected to be $0.04 to $0.09 per share. Full year 2001 revenues are expected to be $1.54 billion to $1.55 billion, and EBITDA to be $72.5 million to $75.5 million. Full year net income is expected to be $11.7 million to $13.5 million, and earnings per share are expected to be $0.31 to $0.36 per share. The above results include a charge relating to the Company's receivables with Kmart, in light of that company's recent bankruptcy filing. This charge is expected to be $3.5 million to $4.5 million. Excluding this charge, EBITDA in the fourth quarter is expected to be $20 million to $22 million, and for the full year, $77 million to $79 million. Net income excluding this charge is expected to be $4.3 million to $5.5 million for the fourth quarter, and $14.3 million to $15.5 million for the full year. Earnings per share excluding this charge are expected to be $0.12 to $0.15 per share in the fourth quarter, and $0.39 to $0.42 for the full year. Excluding the Kmart charge as well as charges recorded last year for restructuring and nonoperating items, the Company expects to report increased EBITDA, net income, and earnings per share for the fourth quarter. Full year 2001 EBITDA, net income and earnings per share are expected to exceed comparable 2000 results with and without the Kmart charge. Free cash flow for the fourth quarter was approximately $24 million and for the full year approximately $62 million. Total debt declined approximately $29 million during the fourth quarter and approximately $69 million during the year to end 2001 at approximately $205 million. The Company's lenders have agreed to exclude the Kmart charge from covenant consideration. Accordingly, the Company expects to be in compliance with all bank covenants as of yearend. Full fourth quarter and annual results for 2001 are expected to be announced by the Company in the first half of March. Excluding the results of the 19 operations being divested as well as the Kmart charge, the Company's adjusted revenues would have been $880 million to $890 million, and adjusted EBITDA would have been $31 million to $33 million. This adjusted EBITDA amount includes full actual 2001 corporate costs and reflects no estimate of any potential reductions in such costs in response to this major change in the Company. Substantially all of the Kmart charge relates to operations not being divested and would reduce adjusted EBITDA accordingly. Following closing of this transaction, the Company expects total debt to be $45 million to $55 million, and total debt to EBITDA (based on trailing twelve month results excluding divested entities) of 1.40 to 1.80. The Company has agreed with its lenders to a reduction in its revolving credit facility to $100 million upon closing. Borrowings under the revolver are expected to be $30 million to $40 million subsequent to closing.

Bill Murdy continued, "We are parting with some excellent people and organizations that have been valuable members of our team. We thank them for their important contributions to Comfort Systems USA's success. Going forward, the Company retains a broad national footprint that includes substantially the same technical and operating capabilities it has today. Moreover, we have put the Company on a very firm financial footing that allows for even greater emphasis on service, energy and automation growth in our business. We look forward to renewed performance and success at Comfort Systems USA." Comfort Systems USA is a premier provider of business solutions addressing workplace comfort, environments, processes and energy services.
