To Our Stockholders:

     You are cordially invited to attend the annual meeting of the stockholders
of Comfort Systems USA, Inc., which will be held on Thursday, May 23, 2002 at
the DoubleTree Hotel, 2001 Post Oak Boulevard, Houston, Texas, 77056, at 11:00
a.m.

     At this meeting stockholders are being asked to elect three Class II
directors to serve for three years and to approve an amendment to our
Non-Employee Directors' Stock Plan to increase the number shares that are
available and to increase the number of shares that are annually issued to our
outside directors. During the past year we have fundamentally restructured our
Board of Directors, and it now has a majority of members from outside of the
Company. I believe that the proposed changes are important to help us maintain
and strengthen a Board of Directors that will provide strong leadership in
maximizing stockholder value.

     Please read the proxy statement, which describes the proposals to be voted
on and also presents other important information. When you have finished reading
the statement, please promptly mark, sign, and return your proxy card in the
enclosed envelope so that your shares will be represented.

look forward to seeing you there.

                             ---------------------

                         ANNUAL MEETING OF STOCKHOLDERS
                                  MAY 23, 2002

                             ---------------------

                                PROXY STATEMENT

     The Annual Report to Stockholders, which includes the Company's Annual
Report on Form 10-K for the Company's fiscal year ended December 31, 2001,
accompanies this proxy statement. This proxy statement and the enclosed proxy
are being mailed to stockholders on or about April 15, 2002.

     The enclosed proxy is solicited by and on behalf of the Board of Directors
of Comfort Systems USA, Inc. (the "Company"), to be voted at the Annual Meeting
of Stockholders (the "Meeting") to be held at the DoubleTree Hotel, 2001 Post
Oak Boulevard, Houston, Texas, 77056, at 11:00 a.m. on Thursday, May 23, 2002,
and at any adjournments thereof. A proxy may be revoked by a stockholder at any
time before it is voted by (i) returning to the Company another properly signed
proxy bearing a later date, (ii) delivering a written revocation to the
Secretary of the Company or (iii) attending the Meeting or any adjourned session
thereof and voting the shares covered by the proxy in person. Shares represented
by the enclosed form of proxy properly executed and returned, and not revoked,
will be voted at the Meeting by the person named in the proxy for the proposals
set forth below.

     The Company will pay the expense of soliciting proxies. In addition to the
solicitation of proxies by use of the mails, the Company may use the services of
its officers and regular employees as well as brokerage houses and other
stockholders to solicit proxies personally and by mail and telephone. The
Company will reimburse brokers and other persons for their reasonable charges
and expenses in forwarding soliciting materials to their principals. Officers
and employees of the Company will receive no compensation in addition to their
regular salaries to solicit proxies.

     The holders of record of shares of the common stock, $.01 par value per
share (the "Common Stock"), and of the restricted common stock, $.01 par value
per share (the "Restricted Common Stock"), of the Company at the close of
business on April 9, 2002 (the "Record Date") are entitled to receive notice of
and to vote at the Meeting. As of the Record Date, the Company had issued and
outstanding 36,560,253 shares of Common Stock and 1,191,112 shares of Restricted
Common Stock, for a total of 37,751,365 shares outstanding. Each share of Common
Stock is entitled to one vote on each matter before the Meeting, except for the
election of one director designated to be elected solely by holders of the
Restricted Common Stock. Each share of Restricted Common Stock is entitled to
.55 of one vote on each matter before the Meeting; except that holders of
Restricted Common Stock are not eligible to vote for any directors other than
the one Class II director designated to be elected by them.

     Consistent with Delaware law and the Company's Bylaws, a majority of the
voting power of shares entitled to be cast on a particular matter, present in
person or represented by proxy, constitutes a quorum as to such matter. Votes
cast by proxy or in person at the meeting will be counted by two persons
appointed by the Company to act as election inspectors for the meeting. In the
absence of contrary instructions, the persons named as proxies will vote FOR all
nominees listed in Proposal 1 and FOR Proposal 2.

     With respect to Proposal 1, there are three nominees for election as Class
II director. Two of these nominees, J. Gordon Beittenmiller and Robert D.
Wagner, Jr., are the nominees for the two Class II directors to be elected
solely by the holders of Common Stock. One nominee, Steven S. Harter, is the
nominee for the one director to be elected solely by the holders of Restricted
Common Stock. Consequently, a vote by a holder of Common Stock FOR the nominees
identified on the proxy card is a vote in favor of Messrs. Beittenmiller and
Wagner only; and a vote by a holder of Restricted Common Stock FOR the nominees
identified on the proxy card is a vote in favor of Steven S. Harter only. The
two nominees for election as Class II directors


receiving the greatest number of votes properly cast on behalf of holders of
Common Stock for the election of directors at the Meeting will be elected. The
one nominee for election as a Class II director receiving the greatest number of
votes properly cast on behalf of all holders of Restricted Common Stock will be
elected. Mr. Harter owns a majority of the Restricted Common Stock and therefore
a vote by Mr. Harter in favor of his own reelection will ensure that result. In
the election of directors, votes may be cast in favor of or withheld with
respect to any or all nominees; votes that are withheld will be excluded
entirely from the vote and will have no effect on the outcome of the vote.

     Proposal 2 is to approve an amendment to the Company's 1997 Non-Employee
Directors' Stock Plan to (i) increase the number of shares issuable pursuant to
that Plan by 250,000 shares and (ii) change the number of shares underlying
options that are automatically granted to non-employee directors at the time of
each annual meeting from 5,000 to 10,000. Approval of Proposal 2 requires the
affirmative vote of the majority of the votes properly cast by holders of shares
of Common Stock and Restricted Common Stock, voting together at the Meeting.
Abstentions therefore will have no effect on Proposal 2. Each share of
Restricted Common Stock is entitled to .55 of one vote with respect to this
Proposal. Shares represented by proxies in the form enclosed, if properly
executed and returned and not revoked, will be voted as specified, but where no
specification is made, the shares will be voted in favor of Proposal 2.

                               PROPOSAL NUMBER 1

                         ELECTION OF CLASS II DIRECTORS

     The Board of Directors is divided into three classes, as nearly equal in
number as possible, with each class serving a three-year term. At each Annual
Meeting of Stockholders, one class of directors will be elected for a full term
of three years to succeed that class of directors whose terms are expiring. The
terms of the current Class II, III and I directors expire at the Annual Meeting
of Stockholders in 2002, 2003 and 2004, respectively. All officers serve at the
discretion of the Board of Directors.

     The three nominees for election as Class II directors are J. Gordon
Beittenmiller, Robert D. Wagner, Jr. and Steven S. Harter (collectively the
"Nominees"). The Nominees presently serve as the three directors designated as
Class II directors and their current terms expire at the Meeting. Holders of
Common Stock are entitled to vote in favor of two directors. Messrs
Beittenmiller and Wagner are the nominees for the holders of Common Stock. A
vote by a holder of Common Stock FOR the nominees identified on the proxy card
is a vote in favor of Messrs. Beittenmiller and Wagner only. Holders of
Restricted Common Stock are entitled to vote in favor of one director only.
Steven S. Harter is the Nominee for the holders of Restricted Common Stock. A
vote by a holder of Restricted Common Stock FOR the nominees identified on the
proxy card is a vote in favor of Steven S. Harter only. Mr. Harter owns a
majority of the Restricted Common Stock and therefore a vote by Mr. Harter in
favor of his reelection will ensure that result.

     If elected, each nominee would serve for a term of three years expiring at
the 2005 Annual Meeting of Stockholders, and until his or her respective
successor is elected and qualified to serve. It is expected that all of the
Nominees will be able to serve, but if any Nominee is unable to serve, the
proxies reserve discretion to vote, or refrain from voting, for a substitute
nominee.

                                    NOMINEES

of the Board, evaluate new members as appropriate with an emphasis on diversity
of viewpoint and background, review the compensation structure and meeting
frequency and content, and to make recommendations to the Board on all such
matters. Stockholders may contact the Committee in care of the Company's General
Counsel's office with suggestions regarding governance or board membership.

                             DIRECTOR COMPENSATION

     Directors who are also employees of the Company or one of its subsidiaries
are not entitled to receive additional compensation for serving as directors.
Each director who is not an employee of the Company or one of its subsidiaries
receives a fee of $2,000 for attendance at each Board of Directors meeting and
$1,000 for each committee meeting (unless held on the same day as a Board of
Directors meeting). Directors are also reimbursed for out-of-pocket expenses
incurred in attending meetings of the Board of Directors or committees thereof.

     In addition, the Company's 1997 Non-Employee Directors' Stock Plan (the
"Directors' Plan"), which was adopted by the Board of Directors and approved by
the Company's stockholders in March 1997, currently provides for (i) the
automatic grant to each non-employee director of an option to purchase 10,000
shares upon such person's initial election as a director and (ii) an automatic
annual grant to each non-employee director of an option to purchase 5,000 shares
at each annual meeting of stockholders thereafter at which such director is
re-elected or remains a director, unless such annual meeting is held within
three months of such person's initial election as a director. If Proposal 2 is
approved, the shares underlying the automatic annual
                                        5


option grant to non-employee directors will be increased to 10,000 shares. All
options have an exercise price per share equal to the fair market value of the
Common Stock on the date of grant, are immediately vested and expire on the
earlier of ten years from the date of grant or one year after termination of
service as a director. The Directors' Plan also permits non-employee directors
to elect to receive, in lieu of cash directors' fees, shares or credits
representing "deferred shares" at future settlement dates, as selected by the
director. The number of shares or deferred shares received will equal the number
of shares of Common Stock which, at the date the fees would otherwise be
payable, will have an aggregate fair market value equal to the amount of such
fees. Of the 250,000 shares of Common Stock initially available under the
Directors' Plan, and without giving effect to the proposed amendment or
issuances to be made in connection with the 2002 annual meeting of stockholders,
125,000 shares remained available as of the date of this proxy statement.

     The Company has also indemnified each director who was in office at the
time of the initial public offering, as more particularly described in the
section that follows entitled "COMPENSATION OF EXECUTIVE OFFICERS."

     The two nominees for election as Class II directors receiving the greatest
number of votes properly cast on behalf of holders of Common Stock and the one
nominee for election as a Class II director receiving the greatest number of
votes properly cast on behalf of holders of the Restricted Common Stock for the
election of directors at the Meeting will be elected. The persons named in the
enclosed proxy intend to vote each share as to which a proxy has been properly
executed and returned (and not revoked) in favor of the election as a Class II
director of each of the nominees named below, unless authority to vote for the
election of any of such nominees is withheld by marking the proxy to that
effect. The election inspectors will count shares of Common Stock represented by
proxies that withhold authority to vote for one or more nominees for election as
a director only as shares that are present and entitled to vote on the matter
for purposes of determining the presence of a quorum, but withholding authority
to vote for one or more nominees will not have any effect on the outcome of
voting on this proposal.

           THE BOARD OF DIRECTORS RECOMMENDS ELECTION OF THE NOMINEES
                        DESCRIBED IN PROPOSAL NUMBER 1.

                               PROPOSAL NUMBER 2

                       APPROVAL OF THE AMENDMENTS TO THE
                    1997 NON-EMPLOYEE DIRECTORS' STOCK PLAN

     On March 22, 2002 the Company's Board of Directors approved, subject to
stockholder approval, certain amendments to the 1997 Non-Employee Directors'
Stock Plan (the "Plan").

     The purpose of the Plan is to advance the interests of the Company and its
stockholders by providing a means to attract and retain highly qualified persons
to serve as non-employee directors of the Company and to enable those persons to
acquire or increase a proprietary interest in the Company, thereby promoting a
closer identity of interests between those persons and the Company's
stockholders. The Plan is intended to accomplish these goals by providing for
the grant of stock options to non-employee directors and by providing a
mechanism through which non-employee directors may elect to be paid fees in the
form of stock or deferred stock, all as more fully described below. During the
past year the composition of the Board of Directors has changed and non-employee
directors now constitute a majority of the directors. The Board of Directors
believes that the adoption of the amendments is in the stockholders interest in
order to permit the Company to maintain and strengthen independent governance of
the Company.

                              PROPOSED AMENDMENTS

     The proposed amendments to the Plan would (i) increase the number of shares
reserved and available for issuance under the Plan from 250,000 to 500,000 and
(ii) increase the annual automatic stock option grants to non-employee directors
from options to purchase 5,000 shares to options to purchase 10,000 shares. If
the amendments are approved, the increase in the number of shares underlying the
annual automatic stock option

                                        6


grant will be effective for option grants occurring at the close of business of
the May 23, 2002 annual meeting of stockholders. As of April 9, 2002, the
closing price of the Company's Common Stock was $4.88 per share.

                            DESCRIPTION OF THE PLAN

     The Board of Directors administers the Plan. A total of 250,000 shares of
Stock currently are reserved for issuance under the Plan. If Proposal 2 is
approved, this total will increase to 500,000 shares. Directors of the Company
who are not employees of the Company or any subsidiary of the Company are
eligible to participate in the Plan. Currently, there are five non-employee
directors on the Board.

     Stock Options.  The Plan currently provides for (i) the automatic grant to
each non-employee director of an option to purchase 10,000 shares upon such
person's initial election as a director, and (ii) an automatic annual grant to
each non-employee director of an option to purchase 5,000 shares at the close of
business of each annual meeting of stockholders thereafter at which such
director is re-elected or remains a director, unless such annual meeting is held
within three months of such person's initial election as a director. If Proposal
2 is approved, the automatic annual grant will be increased to an option to
purchase 10,000 shares. All options have an exercise price per share equal to
the fair market value of the Common Stock on the date of the grant, are
immediately vested, and expire on the earlier of ten years from the date of
grant or one year after termination of service as a director. Options may be
exercised by giving notice to the Company and paying the exercise price in cash,
by check, by surrender of shares already owned by the participant, or through a
combination of the foregoing.

     Receipt of Shares or Deferred Shares in Lieu of Fees.  The Plan provides
that non-employee directors may elect to receive, in lieu of cash directors'
fees, shares of Common Stock or credits representing "deferred shares" of Common
Stock. The number of shares or deferred share credits received by an electing
non-employee director is equal to the number of shares of Common Stock that have
an aggregate fair market value equal to the amount of such fees as of the date
that such fees would be payable in the absence of an election to receive shares
or deferred shares. In a case in which a non-employee director elects to receive
shares currently, fractional share amounts may be paid in cash. Non-employee
directors who maintain a deferred share account are credited with additional
deferred share credits for dividends paid on the Common Stock. Deferred share
accounts are settled with the delivery of shares and, in the case of fractional
shares, cash. The Company will settle any deferred share account balance that
remains outstanding at the time of a participant's resignation from the Board of
Directors within 30 days of such participant's resignation from the Board of
Directors.

     Adjustments and Amendment.  In the event of any recapitalization, stock
split, reorganization, merger, or similar transaction, adjustments to the Plan
shall be made as necessary to maintain the proportionate interests of the
participants. Adjustments may include changes in the number and kind of shares
available under the Plan, the number and kind of shares issued under options and
the exercise price of such options, and the number and kind of shares to be
delivered in settlement of deferred share accounts. Except to the extent that
stockholder approval is required by law, regulation, or exchange or automated
quotation system rules, the Board may amend, suspend, or terminate the Plan
without stockholder or participant approval, except that no such action may
materially impair the rights of a participant with respect to previously granted
options or previous payment of fees in the form of shares or deferred shares
without the consent of such participant.

     Transferability.  Options, deferred shares, and other rights under the Plan
are not transferable by the participant other than by will, by the laws of
descent and distribution, or to a designated beneficiary in the event of a
participant's death, and are exercisable during the lifetime of a participant
only by the participant or his or her guardian or legal representative. However,
a participant may transfer options and deferred shares to a trust or trusts or
to other beneficiaries for the purposes of the participant's estate planning,
and such transferees may exercise the rights provided in the Plan to the extent
permitted and consistent with the rules of the Securities and Exchange
Commission.

                                        7


                               NEW PLAN BENEFITS

     If the proposed amendments to the Plan are approved, each non-employee
director who is eligible to receive an automatic annual option will receive an
option to purchase 10,000 shares of stock at the close of the May 23, 2002
annual meeting of stockholders, instead of an option to purchase 5,000 shares.

                              FEDERAL TAX EFFECTS

     The following discussion summarizes certain federal income tax consequences
of participation in the Plan. The summary does not purport to cover federal
employment tax or other federal tax consequences that may be associated with the
Plan, nor does it cover state, local or non-U.S. taxes.

     Options.  Options granted under the Plan are nonstatutory options. In
general, in the case of a nonstatutory option, the optionee has no taxable
income at the time of grant but realizes income in connection with exercise of
the option in an amount equal to the excess (at the time of exercise) of the
fair market value of the shares acquired upon exercise over the exercise price;
a corresponding deduction is available to the Company; and upon a subsequent
sale or exchange of the shares, appreciation or depreciation after the date of
exercise, to the extent recognized as a gain or loss in connection with the sale
or exchange, is treated as capital gain or loss for which the Company is not
entitled to a deduction.

     Deferred Shares.  The election to receive deferred shares in lieu of cash
directors' fees is intended to defer the participant's recognition of
compensation for Federal tax purposes. If, as is provided for under the Plan, an
individual elects irrevocably to defer compensation prior to the year in which
the compensation is earned and the obligation to provide compensation in the
future is an unsecured, general obligation of the Company, the individual will
not be taxed until the compensation is paid, at which time the Company will be
entitled to a corresponding deduction.

       THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" PROPOSAL NUMBER 2.

(1) These stock options, which were granted pursuant to the Company's 1997 Long
    Term Incentive Plan, were granted at the fair market value of the underlying
    option shares on the date of grant. The grant for each individual will vest
    at the rate of 25% per year, commencing on the first anniversary of the date
    of grant, and will expire at the earliest of ten years from the date of
    grant or three months following termination of employment. In the event of a
    change in control of the Company, all options would become exercisable in
    full. Stock options reported consist of non-qualified stock options.

(2) These numbers are based upon the fair market value of the Common Stock on
    the grant date and the annual appreciation of such value through the
    expiration date of such options, assuming the 5% and 10% annual appreciation
    rates set by the SEC for illustrative purposes. These numbers are not

                EMPLOYMENT AGREEMENTS; COVENANTS NOT TO COMPETE;
                       CHANGE OF CONTROL; INDEMNIFICATION

     During 2001, the Company's five most highly compensated executive officers
were Messrs. Murdy, Hess, Beittenmiller, George and Honeycutt.

     On June 27, 2000 Mr. Murdy entered into an employment agreement with the
Company. Mr. Murdy's employment agreement provides for an annual base salary of
$400,000. Mr. Murdy's employment agreement is for a term of three years, and
unless terminated or not renewed by the Company or the employee, the term will
continue thereafter on a year-to-year basis on the same terms. The current term
renews or expires in June 2003. The agreement provides that, in the event of a
termination of employment by the Company without cause, Mr. Murdy would receive
from the Company an amount equal to the greater of base salary for the remaining
term or for one year. In the event of a change in control of the Company (as
defined in the employment agreement) the Employee may elect to terminate his
employment and receive an amount equal to two times his annual base salary then
in effect. The employment agreement contains a covenant not to compete with the
Company for two years immediately following termination of employment. In the
event of a change in control, the non-competition provisions apply for a period
of one year immediately following the effective date of termination.

     On June 27, 1997, Mr. Beittenmiller and Mr. George entered into an
employment agreement with the Company providing for an annual base salary of
$150,000 and Mr. Honeycutt entered into an employment agreement with the Company
on January 21, 1998 providing for an annual base salary of $110,000. Each
employment agreement is for a term of three years, and unless terminated or not
renewed by either the Company or the employee, the term will continue thereafter
on a year-to-year basis on the same terms. The current term for all three
individuals will renew or expire in June 2003. The agreement provides that, in
the event of a termination of employment by the Company without cause, the
employee will receive an amount equal to base salary for one year. In the event
of a change in control of the Company, if the employee is not given at least
five days' notice of the successor's intent to continue the employee's
employment after such change in control, the employee may elect to terminate his
employment and receive an amount equal to three times the amount he would
receive pursuant to a termination without cause. The non-competition provisions
of the employment agreement do not apply to a termination without such notice.
In the event the employee is given at least five days' notice of the successor's
intent to continue the employee's employment after such change in control, the
employee may elect to terminate his employment and receive two times the amount
he would receive pursuant to a termination without cause. In such event, the
non-competition provisions of the employment agreement would apply for two years
from the effective date of termination. Each employment agreement contains a
covenant not to compete with the Company for two years immediately following
termination of employment or, in the case of a termination by the Company
without cause, for one year.

     On March 31, 2002 Mr. Hess ceased to be the Company's President and Chief
Operating Officer and his prior Employment Agreement was mutually terminated. In
connection with his departure, the Company paid Mr. Hess $250,000 in severance.
The Company continues to employ Mr. Hess on a part-time basis at an annual
salary of $42,860, although Mr. Hess is not eligible for benefits. Mr. Hess'
agreement with respect to such part-time employment will expire on September 30,
2005. In the event of a change in control of the Company or if he is terminated
without cause, the Company must pay Mr. Hess a lump-sum equal to all of the
remaining salary payable under the agreement, and in such a case any options
that he holds will be vested, provided, however, in the event Mr. Hess accepts
full-time employment with any third party or associates himself in any capacity
with a third party engaged in providing competing services, the Company may
terminate the agreement with no further obligations.

     Each executive officer and director of the Company who was in office at the
time of the initial public offering has entered into an Indemnification
Agreement with the Company whereby the Company indemnifies each against actions
taken in good faith on behalf of the Company.

                         REPORT OF THE AUDIT COMMITTEE

     The Audit Committee of the Board of Directors of the Company (the "Audit
Committee") oversees the Company's financial reporting process on behalf of the
Board of Directors. Management has the primary responsibility for the financial
statements and the reporting process including the Company's internal controls.
In fulfilling its oversight responsibilities, the Audit Committee has reviewed
the audited financial statements in the Annual Report with management. The
discussion explored the quality, not just the acceptability, of the accounting
principles, the reasonableness of significant judgments, and the clarity of each
of the key disclosures in the financial statements.

     The Audit Committee reviewed with the independent auditors, who are
responsible for expressing an opinion on the conformity of those audited
financial statements with generally accepted accounting principles, their
judgments as to the quality, not just the acceptability, of the Company's
controls, reporting and accounting principles and such other matters as are
required to be discussed with the Audit Committee under generally accepted
auditing standards. In addition, the Audit Committee has reviewed and discussed
with the independent auditors the auditors' independence from management and the
Company including all written disclosures required by the Independence Standards
Board. The Committee has also considered whether the provision of other
non-audit professional services provided to the Company by the independent
auditors is compatible with maintaining the auditors' independence and has
discussed with the auditors the auditors' independence.

     The Audit Committee discussed with the Company's internal and independent
auditors the overall scope and plans for their respective audits. The Audit
Committee meets regularly with the external auditors, with and without
management present, to discuss the results of their examinations, their
evaluations of the Company's internal controls, and the content and quality of
the Company's financial reporting. In reliance on the review and discussions,
the Audit Committee recommended to the Board of Directors that the audited
financial statements be included in the Annual Report of Form 10-K for the
fiscal year ended December 31, 2001 and for filing with the Securities and
Exchange Commission.

     The members of the Audit Committee have been determined to be independent
and financially literate (as independence and financial literacy is defined by
the New York Stock Exchange listing standards) by the Board of Directors.

         REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

     The Compensation Committee establishes and administers the Company's
executive compensation program and reviews and advises the Board of Directors
with respect to major organizational changes, leadership development and
leadership succession issues. The Committee establishes and regularly reviews
the compensation levels of executive officers and other key managers, and
reviews incentive awards.

     The central objectives of the Company's executive compensation program are
to:

     - Retain and attract competent leaders by providing reasonable but
       competitive compensation;

     - Provide incentives for achieving and exceeding the Company's performance
       goals; and

     - Align the financial interests of the Company's executives with those of
       its stockholders.

     The Committee believes that total compensation levels at the Company are
consistent with and in most instances are below the average compensation at
comparable companies. This reflects the history of the Company, its status as a
Company in transition, and the economic realities of the Company's business and
the general economy.

     The Company's executive compensation program is designed to provide
advantageous levels of incentive and stock-based returns as the Company improves
its profitability. When the Company's stockholders observe improved Company
results through improving balance sheet strength and earnings, the Company's
executives will be appropriately compensated. If the Company does not make
acceptable progress, the total compensation of Company executives will remain
below the levels the Committee believes are typically found at comparable
business entities.

     Three main elements comprise the Company's compensation program: base
salary, annual bonus incentives, and long-term incentives.

     Base Salary -- Individual executive salaries and the aggregate salary
expense for the executive officers are reviewed annually by the Committee. The
Committee considers performance, labor market conditions, the Company's results,
the Company's budget, and salary levels as compared to market levels of
compensation. For 2001, the three highest paid executive officers did not
receive a salary increase; certain other executive officers received modest
increases from their 2000 compensation levels.

     Annual Bonus Incentives -- Annual bonus incentives for executive officers
are based upon objectives that may include earnings, cash flow, growth,
strategic initiatives and individual performance. In 2001, the Bonus Plan for
Executive Officers was based upon objective measurement of the lesser of
operating income and the level of positive cash flow. Because positive cash flow
greatly exceeded operating income in 2002, the relevant constraint for bonuses
paid in 2001 was operating income. Under the plan, if the target levels were
met, the three most highly compensated officers were eligible to receive a bonus
of up to 100% of their base salary, and the remaining officers were eligible to
receive a bonus of up to 75% of base salary. For all executive officers except
the three most highly compensated, 25% of their maximum bonus potential of 75%
was also subject to the accomplishment of individual objectives as determined by
the Compensation Committee with the advice of the Chief Executive Officer. Under
the relevant measures, although performance met the minimum requirements to be
in the range in which executive employees were bonus eligible, performance fell
short of the primary targets and thus the amount of bonus paid for 2001 included
in the "Summary Compensation Table" reflects the payment of a partial bonuses
calculated in accordance with the plan.

     Long-Term Incentives (Stock Options) -- Stock-based awards are the primary
tools that the Committee employs to align the long-term financial incentives of
its executive officers with those of its stockholders. In determining the nature
and amount of the awards, the Committee considers the executive's position,
individual performance and the executive's prospects for sustained contribution
to the success of the Company. The exercise price of stock options is no less
than 100% of the share price on the grant date. The options granted in 2001 have
a ten-year term and become exercisable ratably over the first four years
following the grant date. For the foreseeable future, the Company expects that
shares issuable pursuant to options will be taken from shares which were
previously issued and outstanding and which were reacquired by the

                                        14


Company. In late 2001, an aggregate of 125,000 options were granted to five
individuals, and these grants are included above in the table titled "Option
Grants in Last Fiscal Year".

     After a drop in the Company stock price occurred in 1999-2000, the
Committee considered "repricing" options as a means to retain the more than
1,000 employees that held Company options. After consideration, the Committee
and the Board decided not to "reprice" options, and instead sought and received
explicit stockholder approval in May 2000 for a limited number of additional
options to address compensation and retention needs. In July 2000, the Company
experienced a change of top leadership in which all of the options of the
departing Chief Executive Officer were cancelled. In November 2000, the Company
granted options to both new employees and to key existing employees. Many of
those receiving options in that grant had other options with exercise prices at
values exceeding the Company's stock price, however, less than half of the
existing employees who previously held options received new grants, and such
grants were in amounts determined based on Company interests without reference
to existing option amounts. Since that time, the Company has continued a policy
of not "repricing" options. The Company has never retired nor changed the
exercise price of any existing option.

     Policy on Deductibility of Compensation -- Section 162(m) of the Internal
Revenue Code limits the tax deduction to $1 million for compensation paid to
executive officers, unless certain requirements are met. One of these
requirements is that compensation over $1 million must be based upon Company
attainment of performance goals approved by the stockholders. The Company's
plans relating to stock based incentives, which were approved by stockholders,
are designed to meet these requirements. Compensation levels at the Company do
not generally exceed the limitations contained in Section 162(m). It is the
Committee's policy to comply with the requirements of Section 162(m) except
where the Committee determines that compliance is not in the best interests of
the Company or its stockholders.

     The Committee believes that in order for the Company to be successful in
the future it will need to retain its most talented officers and attract
additional high quality leaders. The Committee will continue to use Company
performance as its most significant criteria for determining incentive
compensation. In addition, many officers own a significant number of Company
shares, and beginning in 2002 the Committee expects to emphasize greater stock
ownership by its officers by requiring or encouraging purchases and through the
prudent use of its equity incentive plans.

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Messrs. Bulls, Costantini, Harter and Wagner, none of whom is or was an
executive officer or employee of the Company during 1999, 2000 or 2001, served
on the Compensation Committee during 2001. The Board of Directors has
constituted an Options Approval Committee composed of Messrs. Bulls and
Costantini.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's directors and executive officers and persons who own more than ten
percent of a registered class of the Company's equity securities to file with
the SEC initial reports of ownership and reports of changes in ownership of
Common Stock and other equity securities of the Company. Officers, directors and
greater-than-ten-percent stockholders are required by SEC regulation to furnish
the Company with copies of all Section 16(a) forms they file.

                                        16


     In reviewing the various reports filed with respect to beneficial ownership
under Section 16(a), it was determined that Mr. Murdy's Form 4 for a purchase of
Company shares in August was not prepared and delivered in a timely manner.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Hess Mechanical Corporation, a Delaware corporation ("Hess") and a
subsidiary of the Company, leases its office and warehouse space in Upper
Marlboro, Maryland from Gary E. Hess who was director of the Company during
2001. The lease expires on April 1, 2003, and provides for an annual rental of
$218,600. Hess is responsible for taxes, maintenance and insurance related
thereto. The Company believes that the rent for such property does not exceed
fair market value.

     Shambaugh & Son, L.P., a Texas limited partnership ("Shambaugh") that was a
subsidiary of the Company during 2001, leases its principal offices and
warehouse space in Fort Wayne, Indiana from Mark Shambaugh, who was a director
of the Company during 2001. The lease expires on October 31, 2008, and the
annual rental is $929,472 with annual consumer price index increases. The
Company also leases from Mr. Shambaugh two additional facilities in Fort Wayne,
Indiana, and one additional facility in each of South Bend, Indiana and
Lafayette, Indiana. The additional leases also expire on October 31, 2008 and
provide for annual rentals of $137,328, $12,000, $45,952 and $27,994,
respectively, with annual consumer price index increases. Shambaugh is
responsible for taxes, maintenance and insurance related thereto. Gant/Shambaugh
Group LLC, a construction management company in which Mr. Shambaugh owns a 49%
interest, subcontracted work totaling $4,874,752 during 2001 to Shambaugh. Mr.
Shambaugh also owns CH Kraus L.L.C., a sheetmetal fabricator that sold
sheetmetal fabrication products and services to Shambaugh totaling $5,553,457
during 2001. Shambaugh also leases from Shambaugh Private Carrier Corporation,
an Indiana corporation owned by Mr. Shambaugh, semi-tractors at an annual rental
rate of $76,800 per year. The Company believes these transactions were entered
into at fair market value.

     See the previous section entitled "COMPENSATION COMMITTEE INTERLOCKS AND
INSIDER PARTICIPATION" for other information required to be disclosed here.

     Any future transactions with directors, officers, employees or affiliates
of the Company or its subsidiaries are anticipated to be minimal and will be
approved in advance by a majority of disinterested members of the Board of
Directors.

                                 AUDIT MATTERS

     Arthur Andersen LLP has acted as independent public accountants for the
Company since its inception in 1997. In light of recent, well-publicized events

audit firm that best serves its stockholders' interests for the year ending
December 31, 2002. The Company expects to continue to work with Arthur Andersen
LLP for the financial statement review the first quarter of 2002, but has not
determined whether it will include the firm as an eligible participant in the
selection process. With respect to the 2001 audit, a representative of Arthur
Andersen LLP is expected to be present at the Meeting with the opportunity to

                            COMFORT SYSTEMS USA, INC.

                     1997 NON-EMPLOYEE DIRECTORS' STOCK PLAN

      1. PURPOSE. The purpose of this 1997 Non-Employee Directors' Stock Plan
(the "Plan") of Comfort Systems USA, Inc., a Delaware corporation (the
"Company"), is to advance the interests of the Company and its stockholders by
providing a means to attract and retain highly qualified persons to serve as
non-employee directors of the Company and to enable such persons to acquire or
increase a proprietary interest in the Company, thereby promoting a closer
identity of interests between such persons and the Company's stockholders.

      2. DEFINITIONS. In addition to terms defined elsewhere in the Plan, the
following are defined terms under the Plan:

      (a) "Code" means the Internal Revenue Code of 1986, as amended from time
to time. References to any provision of the Code shall be deemed to include
regulations thereunder and successor provisions and regulations thereto.

      (b) "Deferred Share" means a credit to a Participant's deferral account
under Section 7 which represents the right to receive one Share upon settlement
of the deferral account. Deferral accounts, and Deferred Shares credited
thereto, are maintained solely as bookkeeping entries by the Company evidencing
unfunded obligations of the Company.

      (c) "Exchange Act" means the Securities Exchange Act of 1934, as amended.
References to any provision of the Exchange Act shall be deemed to include rules
thereunder and successor provisions and rules thereto.

      (d) "Fair Market Value" of a Share on a given date mean the last sales
price or, if last sales information is generally unavailable, the average of the
closing bid and asked prices per Share on such date (or, if there was no trading
or quotation in the stock on such date, on the next preceding date on which
there was trading or quotation) as reported in the WALL STREET JOURNAL;
PROVIDED, HOWEVER, that the "Fair Market Value" of a Share subject to Options
granted effective on the date on which the Company commences an Initial Public
Offering shall be the price of the shares so issued and sold, as set forth in
the first final prospectus used in such Initial Public Offering.

      (e) "Initial Public Offering" means an initial public offering of shares
in a firm commitment underwriting registered with the Securities and Exchange
Commission in compliance with the provisions of the Securities Act of 1933, as
amended.

      (f) "Option" means the right, granted to a director under Section 6, to
purchase a specified number of Shares at the specified exercise price for a
specified period of time under the Plan. All Options will be non-qualified stock
options.

      (g) "Participant" means a person who, as a non-employee director of the
Company, has been granted an Option or Deferred Shares which remain outstanding
or who has elected to be paid fees in the form of Shares or Deferred Shares
under the Plan.

      (h) "Rule 16b-3" means Rule 16b-3, as from time to time in effect and
applicable to the Plan and Participants, promulgated by the Securities and
Exchange Commission under Section 16 of the Exchange Act.

      (i) "Share" means a share of common stock, $.01 par value, of the Company
and such other securities as may be substituted for such Share or such other
securities pursuant to Section 8.

      3. SHARES AVAILABLE UNDER THE PLAN. Subject to adjustment as provided in
Section 8, the total number of Shares reserved and available for issuance under
the Plan is 250,000. Such Shares may be authorized but unissued Shares, treasury
Shares, or Shares acquired in the market for the account of the Participant. For
purposes of the Plan, Shares that may be purchased upon exercise of an Option or
delivered in settlement of Deferred Shares will not be considered to be
available after such Option has been granted or Deferred Share credited, except
for purposes of issuance in connection with such Option or Deferred Share;
PROVIDED, HOWEVER, that, if an Option expires for any reason without having been
exercised in full, the Shares subject to the unexercised portion of such Option
will again be available for issuance under the Plan.

      4. ADMINISTRATION OF THE PLAN. The Plan will be administered by the Board
of Directors of the Company; PROVIDED, HOWEVER, that any action by the Board
relating to the Plan will be taken only if, in addition to any other required
vote, such action is approved by the affirmative vote of a majority of the
directors.

      5. ELIGIBILITY. Each director of the Company who, on any date on which an
Option is to be granted under Section 6 or on which fees are to be paid which
could be received in the form of Shares or deferred in the form of Deferred
Shares under Section 7, is not an employee of the Company or any subsidiary of
the Company will be eligible, at such date, to be granted an Option under
Section 6 or receive fees in the form of Shares or defer fees in the form of
Deferred Shares under Section 7. No person other than those specified in this
Section 5 will be eligible to participate in the Plan.

      6. OPTIONS. An Option to purchase 10,000 Shares, subject to adjustment as
provided in Section 8, will be automatically granted, (i) at the commencement of
the Initial Public Offering, to each person who is serving as a director of the
Company at that time or who becomes a director of the Company at that time and
who is eligible under Section 5 at that time, and thereafter (ii) at the
effective date of initial election to the Board of Directors, to each person so
elected who is eligible under Section 5 at that date. In addition, an Option to
purchase 5,000 Shares, subject to adjustment as provided in Section 8, will be
automatically granted, at the close of business of each annual meeting of
stockholders of the Company, to each member of the Board of Directors who is
eligible under Section 5 at the close of business of such annual meeting.
Notwithstanding the foregoing, any person who was automatically granted an
Option to purchase 10,000 Shares at the effective date of initial election to
the Board of Directors shall not be automatically granted an Option

                                      -2-

to purchase 5,000 shares at the first annual meeting of stockholders following
such initial election if such annual meeting takes place within three months of
the effective date of such person's initial election to the Board of Directors.

      (a) EXERCISE PRICE. The exercise price per Share purchasable upon exercise
of an Option will be equal to 100% of the Fair Market Value of a Share on the
date of grant of the Option.

      (b) OPTION EXPIRATION. A Participant's Option will expire at the earlier
of (i) 10 years after the date of grant or (ii) one year after the date the
Participant ceases to serve as a director of the Company for any reason.

      (c) EXERCISABILITY. Each Option may be exercised commencing immediately
upon its grant.

      (d) METHOD OF EXERCISE. A Participant may exercise an Option, in whole or
in part, at such time as it is exercisable and prior to its expiration, by
giving written notice of exercise to the Secretary of the Company, specifying
the Option to be exercised and the number of Shares to be purchased, and paying
in full the exercise price in cash (including by check) or by surrender of
Shares already owned by the Participant having a Fair Market Value at the time
of exercise equal to the exercise price, or by a combination of cash and Shares.

      7. RECEIPT OF SHARES OR DEFERRED SHARES IN LIEU OF FEES. Each director of
the Company may elect to be paid fees, in his or her capacity as a director
(including annual retainer fees for service on the Board, fees for service on a
Board committee, fees for service as chairman of a Board committee, and any
other fees paid to directors) in the form of Shares or Deferred Shares in lieu
of cash payment of such fees, if such director is eligible to do so under
Section 5 at the date any such fee is otherwise payable. If so elected, payment
of fees in the form of Shares or Deferred Shares shall be made in accordance
with this Section 7.

      (a) ELECTIONS. Each director who elects to be paid fees for a given
calendar year in the form of Shares or to defer such payment of fees in the form
of Deferred Shares for such year must file an irrevocable written election with
the Secretary of the Company no later than December 31 of the year preceding
such calendar year; PROVIDED, HOWEVER, that any newly elected or appointed
director may file an election for any year not later than 30 days after the date
such person first became a director, and a director may file an election for the
year in which the Plan became effective not later than 30 days after the date of
effectiveness. An election by a director shall be deemed to be continuing and
therefore applicable to subsequent Plan years unless the director revokes or
changes such election by filing a new election form by the due date for such
form specified in this Section 7(a). The election must specify the following:

            (i) A percentage of fees to be received in the form of Shares or
      deferred in the form of Deferred Shares under the Plan; and

                                      -3-

            (ii) In the case of a deferral, the period or periods during which
      settlement of Deferred Shares will be deferred (subject to such
      limitations as may be specified by counsel to the Company).

      Certain elections may not result in receipt of Shares or deferral of fees
as Deferred Shares.

      (b) PAYMENT OF FEES IN THE FORM OF SHARES. At any date on which fees are
payable to a Participant who has elected to receive such fees in the form of
Shares, the Company will issue to such Participant, or to a designated third
party for the account of such Participant, a number of Shares having an
aggregate Fair Market Value at that date equal to the fees, or as nearly as
possible equal to the fees (but in no event greater than the fees), that would
have been payable at such date but for the Participant's election to receive
Shares in lieu thereof. If the Shares are to be credited to an account
maintained by the Participant and to the extent reasonably practicable without
requiring the actual issuance of fractional Shares, the Company shall cause
fractional Shares to be credited to the Participant's account. If fractional
Shares are not so credited, any part of the Participant's fees not paid in the
form of whole Shares will be payable in cash to the Participant (either paid
separately or included in a subsequent payment of fees, including a subsequent
payment of fees subject to an election under this Section 7).

      (c) DEFERRAL OF FEES IN THE FORM OF DEFERRED SHARES. The Company will
establish a deferral account for each Participant who elects to defer fees in
the form of Deferred Shares under this Section 7. At any date on which fees are
payable to a Participant who has elected to defer fees in the form of Deferred
Shares, the Company will credit such Participant's deferral account with a
number of Deferred Shares equal to the number of Shares having an aggregate Fair
Market Value at that date equal to the fees that otherwise would have been
payable at such date but for the Participant's election to defer receipt of such
fees in the form of Deferred Shares. The amount of Deferred Shares so credited
shall include fractional Shares calculated to at least three decimal places.

      (d) CREDITING OF DIVIDEND EQUIVALENTS. Whenever dividends are paid or
distributions made with respect to Shares, a Participant to whom Deferred Shares
are then credited in a deferral account shall be entitled to receive, as
dividend equivalents, an amount equal in value to the amount of the dividend
paid or property distributed on a single Share multiplied by the number of
Deferred Shares (including any fractional Share) credited to his or her deferral
account as of the record date for such dividend or distribution. Such dividend
equivalents shall be credited to the Participant's deferral account as a number
of Deferred Shares determined by dividing the aggregate value of such dividend
equivalents by the Fair Market Value of a Share at the payment date of the
dividend or distribution.

      (e) SETTLEMENT OF DEFERRED SHARES. The Company will settle the
Participant's deferral account by delivering to the Participant (or his or her
beneficiary) a number of Shares equal to the number of whole Deferred Shares
then credited to his or her deferral account (or a specified portion in the
event of any partial settlement), together with cash in lieu of any fractional
Share remaining at a time that less than one whole Deferred Share is credited to

                                      -4-

such deferral account. Such settlement shall be made within 30 days of the
Participant's resignation from Board of Directors of the Company.

      (f) DELAYED EFFECTIVENESS OF ELECTIONS IN ORDER TO COMPLY WITH RULE 16B-3.
Other provisions of this Section 7 notwithstanding, if any payment of fees in
the form of Shares or deferral of fees in the form of Deferred Shares would
occur (i) less than six months after the Participant filed the election which
would result in such payment or deferral, (ii) at a time when the Company's
employee benefit plans are being operated in conformity with Rule 16b-3 as in
effect on and after May 1, 1991, and (iii) at a time that Rule 16b-3 imposes a
requirement that participant-directed transactions occur more than six months
after the participant's making of an irrevocable election in order for such
transactions to be exempt from Section 16(b) liability, then such fees instead
shall be paid in cash on a non-deferred basis.

      (g) NONFORFEITABILITY. The interest of each Participant in any fees paid
in the form of Shares or Deferred Shares (and any deferral account relating
thereto) at all times will be nonforfeitable.

      8. ADJUSTMENT PROVISIONS.

      (a) CORPORATE TRANSACTIONS AND EVENTS. In the event any dividend or other
distribution (whether in the form of cash, Shares or other property),
recapitalization, forward or reverse split, reorganization, merger,
consolidation, spin-off, combination, repurchase, exchange of Shares or other
securities of the Company, extraordinary dividend (whether in the form of cash,
Shares, or other property), liquidation, dissolution, or other similar corporate
transaction or event affects the Shares such that an adjustment is appropriate
in order to prevent dilution or enlargement of each Participant's rights under
the Plan, then an adjustment shall be made, in a manner that is proportionate to
the change to the Shares and otherwise equitable, in (i) the number and kind of
Shares remaining reserved and available for issuance under Section 3, (ii) the
number and kind of Shares to be subject to each automatic grant of an Option
under Section 6, (iii) the number and kind of Shares issuable upon exercise of
outstanding Options, and/or the exercise price per Share thereof (provided that
no fractional Shares will be issued upon exercise of any Option), (iv) the kind
of Shares to be issued in lieu of fees under Section 7, and (v) the number and
kind of Shares to be issued upon settlement of Deferred Shares under Section 7.
In addition, the Board of Directors is authorized to make such adjustments in
recognition of unusual or non-recurring events (including, without limitation,
events described in the preceding sentence) affecting the Company or any
subsidiary or the financial statements of the Company or any subsidiary, or in
response to changes in applicable laws, regulations or accounting principles.
The foregoing notwithstanding, no adjustment may be made hereunder except as
will be necessary to maintain the proportionate interest of the Participant
under the Plan and to preserve, without exceeding, the value of outstanding
Options and potential grants of Options and the value of outstanding Deferred
Shares.

      (b) INSUFFICIENT NUMBER OF SHARES. If at any date an insufficient number
of Shares are available under the Plan for the automatic grant of Options or the
receipt of fees in the form of Shares or deferral of fees in the form of
Deferred Shares at that date, Options will first be automatically granted
proportionately to each eligible director, to the extent Shares are

                                      -5-

then available (provided that no fractional Shares will be issued upon exercise
of any Option) and otherwise as provided under Section 6, and then, if any
Shares remain available, fees shall be paid in the form of Shares or deferred in
the form of Deferred Shares proportionately among directors then eligible to
participate to the extent Shares are then available and otherwise as provided
under Section 7.

      9. CHANGES TO THE PLAN. The Board of Directors may amend, alter, suspend,
discontinue, or terminate the Plan or authority to grant Options or pay fees in
the form of Shares or Deferred Shares under the Plan without the consent of
stockholders or Participants, except that any amendment or alteration will be
subject to the approval of the Company's stockholders at or before the next
annual meeting of stockholders for which the record date is after the date of
such Board action if such stockholder approval is required by any federal or
state law or regulation or the rules of any stock exchange or automated
quotation system as then in effect, and the Board may otherwise determine to
submit other such amendments or alterations to stockholders for approval;
PROVIDED, HOWEVER, that, without the consent of an affected Participant, no such
action may materially impair the rights of such Participant with respect to any
previously granted Option or any previous payment of fees in the form of Shares
or Deferred Shares.

      10. GENERAL PROVISIONS.

      (a) AGREEMENTS. Options, Deferred Shares, and any other right or
obligation under the Plan may be evidenced by agreements or other documents
executed by the Company and the Participant incorporating the terms and
conditions set forth in the Plan, together with such other terms and conditions
not inconsistent with the Plan, as the Board of Directors may from time to time
approve.

      (b) COMPLIANCE WITH LAWS AND OBLIGATIONS. The Company will not be
obligated to issue or deliver Shares in connection with any Option, in payment
of any directors' fees, or in settlement of Deferred Shares in a transaction
subject to the registration requirements of the Securities Act of 1933, as
amended, or any other federal or state securities law, any requirement under any
listing agreement between the Company and any stock exchange or automated
quotation system, or any other law, regulation, or contractual obligation of the
Company, until the Company is satisfied that such laws, regulations, and other
obligations of the Company have been complied with in full. Certificates
representing Shares issued under the Plan will be subject to such stop-transfer
orders and other restrictions as may be applicable under such laws, regulations,
and other obligations of the Company, including any requirement that a legend or
legends be placed thereon.

      (c) LIMITATIONS ON TRANSFERABILITY. Options, Deferred Shares, and any
other right under the Plan will not be transferable by a Participant except by
will or the laws of descent and distribution (or to a designated beneficiary in
the event of a Participant's death), and will be exercisable during the lifetime
of the Participant only by such Participant or his or her guardian or legal
representative; PROVIDED, HOWEVER, that Options and Deferred Shares (and rights
relating thereto) may be transferred to one or more trusts or other
beneficiaries during the lifetime of the Participant for purposes of the
Participant's estate planning or at the Participant's death, and such
transferees may exercise rights thereunder in accordance with the

                                      -6-

terms thereof, but only if and to the extent then permitted under Rule 16b-3 and
consistent with the registration of the offer and sale of Shares related thereto
on Form S-8, Form S-3, or such other registration form of the Securities and
Exchange Commission as may then be filed and effective with respect to the Plan.
The Company may rely upon the beneficiary designation last filed in accordance
with this Section 10(c). Options, Deferred Shares, and other rights under the
Plan may not be pledged, mortgaged, hypothecated, or otherwise encumbered, and
shall not be subject to the claims of creditors of any Participant.

      (d) NO RIGHT TO CONTINUE AS A DIRECTOR. Nothing contained in the Plan or
any agreement hereunder will confer upon any Participant any right to continue
to serve as a director of the Company.

      (e) NO STOCKHOLDER RIGHTS CONFERRED. Nothing contained in the Plan or any
agreement hereunder will confer upon any Participant (or any person or entity
claiming rights by or through a Participant) any rights of a stockholder of the
Company unless and until Shares are in fact issued to such Participant (or
person) or, in the case an Option, such Option is validly exercised in
accordance with Section 6.

      (f) NONEXCLUSIVITY OF THE PLAN. Neither the adoption of the Plan by the
Board of Directors nor its submission to the stockholders of the Company for
approval shall be construed as creating any limitations on the power of the
Board to adopt such other compensatory arrangements for directors as it may deem
desirable.

      (g) GOVERNING LAW. The validity, construction, and effect of the Plan and
any agreement hereunder will be determined in accordance with the laws of the
State of Delaware, without giving effect to principles of conflicts of laws, and
applicable federal law.

      11. STOCKHOLDER APPROVAL, EFFECTIVE DATE, AND PLAN TERMINATION. The Plan
will be effective as of the date of its adoption by the Board, subject to
stockholder approval prior to the commencement of the Initial Public Offering,
and, unless earlier terminated by action of the Board of Directors, shall
terminate at such time as no Shares remain available for issuance under the Plan
and the Company and Participants have no further rights or obligations under the
Plan.

                                      -7-
