2.                                       Shares Subject to Award.  The Award consists of [NUMBER] shares (the “Shares”) of common stock of the Company (“Stock”).  The undersigned’s rights to the Shares are subject to the restrictions described in this Agreement and the Plan (which is incorporated herein by reference with the same effect as if set forth herein in full) in addition to such other restrictions, if any, as may be imposed by law.

3.                                       Meaning of Certain Terms.  Except as otherwise expressly provided, all terms used herein shall have the same meaning as in the Plan.  The term “vest” as used herein with respect to any Share means the lapsing of the restrictions described herein and in the Plan with respect to such Share.

4.                                       Nontransferability of Shares.  The Shares acquired by the undersigned pursuant to this Agreement shall not be sold, transferred, pledged, assigned or otherwise encumbered or disposed of except as provided below and in the Plan

5.                                       Forfeiture Risk.  Except as provided in Section 7(c) of this Agreement, if the undersigned ceases to be employed by the Company and its subsidiaries for any reason, including death, any then unvested Shares acquired by the undersigned hereunder shall be immediately forfeited.  The undersigned hereby (i) appoints the Company as the attorney-in-fact of the undersigned to take such actions as may be necessary or appropriate to effectuate a transfer of the record owner ship of any such Shares that are unvested and forfeited hereunder, (ii) agrees to deliver to the Company, as a precondition to the issuance of any certificate or certificates with respect to unvested Shares hereunder, one or more stock powers, endorsed in blank, with respect to such Shares, and (iii) agrees to sign such other powers and take such other actions as the Company may reasonably request to accomplish the transfer or forfeiture of any unvested Shares that are forfeited hereunder.

6.                                       Retention of Certificates.  Any certificates representing unvested Shares shall be held by the Company.  The undersigned agrees that the Company may give stop transfer instructions to the depository to ensure compliance with the provisions hereof.

7.                                       Vesting of Shares.  The Shares acquired hereunder shall vest in accordance with the provisions of this Paragraph 7 and applicable provisions of the Plan, as follows:

(a)                                  (i)            If the Committee determines that, for the prior 12-month period preceding the first scheduled vesting date set forth in Section 7(b) herein, the Company did not have positive earnings from its continuing operations, all as determined and reported in accordance with generally accepted accounting principles in the Company’s regularly-prepared financial statements, excluding the following non-cash items: (A) good will impairment; (B) write-off of debt costs; (C) restructuring charges; and (D) any cumulative effect of a change in accounting principles, Employee shall immediately and irrevocably forfeit all of the Shares with no consideration due to Employee.

(ii)           If the Committee determines that for the 12-month period prior to the date that such Shares are scheduled to vest under Section 7(b) herein the Company’s prior 36-month performance did not achieve 60% of the average 3-year trailing EBITDA or EPS target (whichever the case may be) as set by the Committee under the average of the Company’s prior 3-year Senior Management Incentive Programs, then Employee shall immediately and irrevocably forfeit all of the Shares scheduled to vest on such date with no consideration due to Employee.

(iii)          If the Committee determines that for the 12-month period prior to the date that such Shares are scheduled to vest under Section 7(b) herein the Company’s prior 36-month performance achieved between 60% to 80% of the average 3-year trailing EBITDA or EPS target (whichever the case may be) as set by the Committee under the average of the Company’s prior 3-year Senior Management Incentive Programs, then Employee shall immediately and irrevocably forfeit Shares proportionately based on a scale where 60% or less equals 0% of Shares retained by Employee and 80% or greater equals 100% of Shares retained by Employee; and all Shares not forfeited pursuant to the aforementioned scale shall vest on such vesting date.

(b)                             Subject to Section 7(a) above and Sections 7(c) and 7(d) below, and provided that the undersigned is then, and since the date of grant has continuously been, employed by the Company or its subsidiaries, then the Shares shall vest as follows:

[1/3 of NUMBER] on May 15, 2009;

[1/3 of NUMBER] on April 1, 2010; and

[1/3 of NUMBER] on April 1, 2011;

provided, however, that, not withstanding anything to the contrary in Section 7(a) above or this Section 7(b), any unvested Shares that have not earlier been forfeited shall vest immediately in the event of (i) a “Change in Control,” as

defined in the undersigned’s change in control agreement, if any, with the Company, or (ii) if the undersigned and Company have not entered into a change in control agreement, in the event the Company experiences a “Change in Control” as defined herein.

(c)                                  Notwithstanding anything to the contrary in Section 7(b) above, if the undersigned retires from the Company at a time when the sum of his or her age in whole years and his or her years of service with the Company (as determined in a manner consistent with the method used for purposes of determining vesting under the Comfort Systems USA, Inc. 401(k) Plan) is at least 75, the undersigned shall be deemed to satisfy the continuous employment condition set forth in Section 7(b) on each vesting date following retirement.

(d)                                 Notwithstanding anything to the contrary in Sections 7(a), 7(b), or 7(c) above, the Committee may, in its sole discretion, reduce the number of shares vesting on any date pursuant to this Award, and may cause any unvested shares under this Award to be forfeited, based on the individual performance of the undersigned as compared with specific individual goals, which may be based on objective or nonobjective factors related to the performance of the undersigned.

8.                                       Legend.  Any certificates representing unvested Shares shall be held by the Company, and any such certificate shall contain a legend substantially in the following form:

THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES OF STOCK REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS (INCLUDING FORFEITURE) OF THE COMPANY’S 2006 EQUITY INCENTIVE PLAN AND A RESTRICTED STOCK AWARD AGREEMENT ENTERED INTO BETWEEN THE REGISTERED OWNER AND COMFORT SYSTEMS USA, INC.  COPIES OF SUCH PLAN AND AGREEMENT ARE ON FILE IN THE OFFICES OF COMFORT SYSTEMS USA, INC.

a.                                       engage, as an officer, director, shareholder, owner, partner, joint venturer, or in a managerial capacity, whether as an employee, independent contractor, consultant or advisor, or as a sales representative, or make guarantee loans or invest, in or for any business engaged in  the business of mechanical contracting services, including heating, ventilation and air conditioning, plumbing, fire protection, piping and electrical and related services (“Services”) in competition with the Company or any of its affiliates within seventy-five (75) miles of where the Company or any affiliated operation or subsidiary conducts business if within the preceding two (2) years the undersigned has had responsibility for, or material input or participation in, the management or operation of such other operation or subsidiary;

b.                                      call upon any person who is, at that time, an employee of the Company or any of its affiliates in a technical, managerial or sales capacity for the purpose or with the intent of enticing such employee away from or out of the employ of the Company or any affiliate;
