benefit reasonably expected to be realized by the indemnified party (or any
consolidated, combined or unitary group of which the indemnified party is also

hereunder shall be increased by the present value (based on a discount factor

the Code) of any Tax cost reasonably expected to be realized by the
indemnified party (or any consolidated, combined or unitary group of which the
indemnified party is also a member) arising from the receipt of any indemnity
payment under Article VIII or Article X ("grossed up" for taxes on such
increase). In computing the amount of any such Tax benefit or Tax cost, the
indemnified party shall be deemed to recognize all other items of gross
income, gain, loss, deduction or credit before recognizing any item arising
from the receipt of any indemnity payment hereunder or the incurrence or
payment of any and all Losses. For the purpose of clarity, it is the parties'
expectation that, for federal income tax purposes, the reasonably expected tax

                               PURCHASE AND SALE

          SECTION 2.1. Purchase and Sale. On and subject to the terms and
conditions of this Agreement, the Seller agrees to sell, and Buyer agrees to
purchase from the Seller, all right, title and interest of Seller in and to
the Interests for the consideration specified in Section 2.2.

          SECTION 2.2. Purchase Price. The Buyer agrees to pay to the Seller
a purchase price (the "Preliminary Purchase Price") equal to the total of (a)
$186,250,000 minus (b) the amount of obligations (including accrued interest)
of the Seller under the promissory notes listed on Schedule 2.2 assumed by the
Buyer on the Closing Date (the "Assumed Obligations"). With respect to a
portion of the Preliminary Purchase Price, $2,500,000 (together with all
interest and profits thereon and proceeds therefrom, the "Adjustment Escrow
Amount") shall be held in escrow to support the adjustment to the Preliminary
Purchase Price described in Sections 2.4 and 2.5 and $5,000,000 (together with
all interest and profits thereon and proceeds therefrom, the "Indemnification
Escrow Amount," together with the Adjustment Escrow Amount, the "Escrow
Amount") shall be held in escrow to support the Seller's indemnification
obligations as provided in Article X. The Preliminary Purchase Price shall be
increased or decreased by the Adjustment Amount in accordance with Section
2.5.

          SECTION 2.3.  Deliveries at Closing.

          (a) The closing of the transactions contemplated by this Agreement
(the "Closing") shall take place at the offices of Simpson Thacher & Bartlett
in New York, New York, commencing at 10:00 a.m. local time on the fifth
Business Day following the satisfaction or waiver of all conditions to the
obligations of the parties to consummate the transactions contemplated hereby
(other than conditions with respect to actions that the respective parties will
take at the Closing itself) or such other date as the Buyer and the Seller may
mutually determine in writing (the "Closing Date").

          (b) At the Closing, in addition to the deliveries required to be
made at or prior to the Closing pursuant to Article VI hereof, (i) the Seller
shall sell, assign and transfer to the Buyer all of the Seller's right, title
and interest in and to the Interests free and clear of all Liens, with all
taxes attributable to the transfer of such Interests duly paid or provided for
by the Seller, and (ii) the Buyer shall (A) pay to the Seller cash in an
amount equal to the Preliminary Purchase Price minus the Escrow Amount by wire
transfer of immediately available funds, (B) assume the Assumed Obligations
pursuant to an assumption agreement in form and substance reasonably
satisfactory to the Seller and (C) deposit the Escrow Amount in accordance
with Section 2.6.

          SECTION 2.4. Adjustment Amount and Payment. The Preliminary Purchase
Price shall be increased or decreased by the Adjustment Amount in accordance
with this Section 2.4. The "Adjustment Amount" (which may be a positive or
negative number) will be equal to the amount determined by subtracting the
Closing Net Asset Value from the Target Net Asset Value. If the Adjustment
Amount is positive, then the Adjustment Amount shall be paid by wire

                                     -9-



transfer of immediately available funds by the Seller to an account specified
by the Buyer, net of the Adjustment Escrow Amount paid to the Buyer pursuant
to the Escrow Agreement. If the Adjustment Amount is negative, then the
Adjustment Amount shall be paid by wire transfer of immediately available
funds by the Buyer to an account specified by the Seller. The payment of the
Adjustment Amount shall be made together with interest at the rate of six
percent (6%) per annum, which interest shall begin accruing on the Closing
Date and end on the date on which the payment of the Adjustment Amount is
made. Within three Business Days after the calculation of the Closing Net
Asset Value becomes binding and conclusive on the parties pursuant to
Section 2.5 of this Agreement, the Seller or the Buyer, as the case may be,
shall pay the Adjustment Amount as provided for in this Section 2.4. The
Preliminary Purchase Price as so adjusted is referred to herein as the
"Purchase Price".

          SECTION 2.5. Adjustment Procedure.

          (a) "Net Asset Value" as of a given date shall mean the amount
calculated by subtracting the liabilities of the Company and the Company
Subsidiaries on a consolidated basis from the assets of the Company and the
Company Subsidiaries on a consolidated basis, in each case determined in
accordance with GAAP applied on a basis consistent with the Seller's past
practice (except as expressly required otherwise by the terms of this
Agreement) and prepared on the same basis and using the same accounting
principles, policies and practices used in the Financial Statements.

          (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.

          (c) If (i) within 60 days following the Closing Date, the Buyer
delivers to the Seller the Closing Financial Statements and the Buyer's
calculation of the Closing Net Asset Value and (ii) within 60 days following
the delivery by the Buyer to the Seller of the documents described in clause
(i) above (the "Objection Period"), the Seller has not delivered to the Buyer
(A) a written notice (the "Objection Notice") stating the Seller's objection
to the Buyer's calculation of the Closing Net Asset Value and the basis for
such objection and (B) a signed statement that includes the Seller's
calculation of the Closing Net Asset Value, then the Closing Net Asset Value
calculated by the Buyer shall be binding and conclusive on the parties. 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). If the
determination of the Closing Net Asset Value is submitted to the Independent
Accountants for resolution, each of the Seller and the Buyer (A) shall
promptly furnish or cause to be furnished to the Independent Accountants such
work papers and other documents and information relating to the Closing
Financial Statements and its calculation of the Closing Net Asset Value as the
Independent Accountants may request and are available to such party or its
agents and (B) shall be afforded the opportunity to present to, and discuss
with, the Independent Accountants any material relating to the Closing
Financial Statements and its calculation of the Closing Net Asset Value.
Within 60 days following the submission of such matter to the Independent
Accountants, the Independent Accountants shall 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). 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. On the Closing Date, the Buyer shall
deposit the Escrow Amount with Bank One National Association (or other
institution selected by the Seller with the reasonable consent of the Buyer),
as escrow agent, such deposit to be governed by the terms set forth herein and
in the Escrow Agreement.

liability company or limited partnership power and authority to conduct its
business as currently conducted, to own its properties and to lease those
properties leased by it. Each Company Subsidiary is duly qualified to do
business as a foreign corporation or business entity and is in good standing
in each jurisdiction in which such qualification is necessary under applicable
Law as a result of the conduct of its business or the ownership of its
properties, except for such failures to be so qualified as would not, either
individually or in the aggregate, have a Material Adverse Effect on the
Company or any Company Subsidiary Group. Schedule 5.3(b) lists (i) each
jurisdiction in which each Company Subsidiary is qualified to do business as a
foreign corporation or other business entity and (ii) the directors and
officers of each Company Subsidiary. The Seller has delivered to the Buyer
true, correct and complete copies of each Company Subsidiary's certificate of

other organizational documents.

          SECTION 5.4. Noncontravention. The execution, delivery and
performance by the Seller of this Agreement and each agreement or instrument
to which it is a party executed and delivered in connection herewith and the
consummation of the transactions contemplated hereby and thereby do not and
will not (a) conflict with or violate any Laws applicable to the Company or
any Company Subsidiary, (b) conflict with or violate any provision of the
certificate of incorporation or by-laws or other organizational documents of
the Company or any Company Subsidiary or (c) violate, result in a breach,
default or acceleration under, or give rise to any penalty or any right of
termination or modification or any other remedy under, any agreement to which
the Company or any Company Subsidiary is a party or by which the Company or
any Company Subsidiary is bound, except for such violations, breaches,
defaults, rights or termination or modification and other remedies as would
not, either individually or in the aggregate, have a Material Adverse Effect
on the Company or any Company Subsidiary Group. No consent, approval,
authorization, license, order or permit of, or declaration, filing or
registration with, or notification to, any Governmental Authority or any other
Person is necessary or required to be made or obtained by the Company, any
Company Subsidiary or any of their respective Affiliates in connection with
the execution and delivery of this Agreement or the consummation of the
transactions contemplated hereby, except for such consents, approvals,
authorizations, licenses, orders, permits, declarations, filings,
registrations and notifications (i) of (A) Governmental Authorities which are
specifically identified on Schedule 5.4(A) or (B) all other third parties
which are specifically identified on Schedule 5.4(B) or (ii) the absence of
which would not, either individually or in the aggregate, have a Material
Adverse Effect on the Company or any Company Subsidiary Group.

          SECTION 5.5. Financial Statements. The Seller has delivered to the
Buyer copies of the Financial Statements set forth on Schedule 5.5. The

          SECTION 5.6. Undisclosed Liabilities. Except as set forth on
Schedule 5.6, neither the Company nor any Company Subsidiary has any material
Liabilities (and there is no basis for any present or future Action against
any of them giving rise to any material Liability), except for (i) Liabilities
set forth on the face of the Most Recent Balance Sheet and (ii) Liabilities
incurred after the date of the Most Recent Balance Sheet in the ordinary
course of business and consistent with past practices; provided that, for
purposes of this Section 5.6, the term "Liability" shall not include any
contractual obligation to the extent such contractual obligation would not be
required to be disclosed as a liability on a balance sheet of the Company or
any Company Subsidiary pursuant to GAAP.

          SECTION 5.7. Absence of Change. Except as set forth in Schedule 5.7
or as contemplated by this Agreement, since September 30, 2001, each of the
Company and the Company Subsidiaries (i) has conducted its business in the

suffered any change in business, financial condition or results of operations
that has had or would be reasonably likely to have a Material Adverse Effect
on the Company or any Company Subsidiary Group, as the case may be, and (ii)
has not taken any action which, if taken after the date hereof, would
constitute a material breach of Section 6.2.

          SECTION 5.8. Assets. Each of the Company and the Company
Subsidiaries has good and marketable title to, or a valid leasehold interest
in, the properties and assets used by it, located on its premises, shown on
the Most Recent Balance Sheet or acquired after the date thereof, free and
clear of all Liens, except for properties and assets disposed of in the
ordinary course of business, consistent with past practice, since the date of
the Most Recent Balance Sheet. All of the buildings, machinery, equipment and
other tangible assets necessary for the conduct of the respective businesses
of the Company and the Company Subsidiaries as currently conducted are in good

the respective businesses of the Company and the Company Subsidiaries. Such
assets and the other properties being leased by each of the Company and the
Company Subsidiaries pursuant to the leases described on Schedule 5.9(b)

of the respective businesses of the Company and the Company Subsidiaries, and
such assets are free from material defects (patent and latent), have been
maintained in accordance with normal industry practice and are sufficient in
quantity and otherwise suitable for the purposes for which they are currently
used. Except as set forth on Schedule 5.9(a) and Schedule 5.9(b), since

     terms following the consummation of the transactions contemplated hereby;

          (iii) to the Knowledge of the Company, no party to the lease or
     sublease is in breach or default in any material respect, and no event
     has occurred which, with notice or lapse of time or both, would
     constitute a material breach or default or permit termination,
     modification or acceleration thereunder;

          (iv) to the Knowledge of the Company, no party to the lease or
     sublease has repudiated any provision thereof;

          (v) except as disclosed in Schedule 5.9(b)(v), there are no

          (vi) with respect to each sublease, neither the Seller, the Company
     nor any Company Subsidiary has received written or oral notice with
     respect to any matter that would cause the representations and warranties
     set forth in subsections (i) through (v) above not to be true and correct
     with respect to the underlying lease;


                                     -19-

          (viii) each Leased Property has received all approvals of

     nor any Company Subsidiary has received written or oral notice that the
     owner of any Leased Property does not have good and marketable title to
     such Leased Property, free and clear of all Liens, except for
     installments of special easements not yet delinquent and recorded
     easements, covenants, and other restrictions which do not impair the

are no Actions instituted, pending or, to the Knowledge of the Company,
proposed or threatened by any third party pertaining to, or challenging, the
Company's or any Company Subsidiary's use of, or right to use, any
Intellectual Property. Neither the Intellectual Property of the Company and
the Company Subsidiaries nor the conduct of the respective businesses of the
Company and the Company Subsidiaries infringes or violates in any material
respect any Intellectual Property or other right of any third party. To the
Knowledge of the Company, no third party is infringing upon any Intellectual
Property of the Company or any Company Subsidiary.

          SECTION 5.11. Compliance with Law. Each of the Company and the

the Company or any Company Subsidiary Group; and (b) is in compliance with all
Laws, except for such failures to so comply as would not, individually or in
the aggregate, have a Material Adverse Effect on the Company or any Company
Subsidiary Group. Since December 31, 2000, neither the Company nor any Company
Subsidiary has received any notice from any Governmental Authority asserting
any failure to comply with any applicable Law, except for such failures to so
comply as would not, individually or in the aggregate, have a Material Adverse
Effect on the Company or any Company Subsidiary Group.

aggregate future payments or receipts in excess of $50,000, other than

          The Seller has delivered to the Buyer true and complete copies of
all such agreements (other than collective bargaining agreements unless
specifically requested), including all amendments, modifications, waivers and
elections applicable thereto, and a written summary setting forth the terms
and conditions of each oral agreement referred to in Schedule 5.12.

          The following representations and warranties are true and correct
with respect to each contract, agreement, or arrangement to which the Company

                                     -22-



          SECTION 5.14. Insurance. Schedule 5.14 sets forth the following
information with respect to each insurance policy (including policies
providing property, casualty, liability, and workers' compensation coverage
and bond and surety arrangements) to which any of the Seller (with respect to
any Company Subsidiary), the Company or any Company Subsidiary has been a

other party thereto, (B) (1) enforceable against the Seller, the Company or

          SECTION 5.15. Employee Benefits.

          (a) Schedule 5.15(a) contains a true and complete list of each
Company Plan and indicates whether such Company Plan is a Transferred Company
Plan.

          (b) With respect to each Company Plan that is not a multiemployer

favorable determination or opinion letter that the form of the plan has
satisfied the requirements of section 401(a) of the Code, and nothing has
occurred, whether by action or failure to act, that would reasonably be
expected to cause the loss of such qualification; (iii) no event has occurred
and no condition exists that would subject the Company or any Company

however, that such examinations and investigations (a) shall be conducted
during the normal business hours of the Company and the Company Subsidiaries
and (b) shall not unreasonably interfere with the operations and activities of
the Company or the Company Subsidiaries. The Company shall cooperate, and

                                     -34-



          SECTION 6.4. Notices and Consents. The Seller, at its expense, will,
and will cause each of the Company and the Company Subsidiaries to, give any
notices to third parties, and to use its or their reasonable best efforts to
obtain any third-party consents, that the Buyer may reasonably request in
connection with the matters referred to in Section 3.3 and Section 5.4;
provided, however, that with respect to the third-party consents identified on
Schedule 3.3(B) and Schedule 5.4(B), the Seller will, and will cause each of
the Company and the Company Subsidiaries to, take any and all actions to

filings with, and use its reasonable best efforts to obtain any
authorizations, consents, and approvals of, Governmental Authorities in
connection with the consummation of the transactions contemplated by this
Agreement. Without limiting the generality of the foregoing, each of the
parties (a) will file (and the Seller will cause each of the Company and the
Company Subsidiaries to file) any notification, report forms and related
material that it may be required to file with the Federal Trade Commission and
the Antitrust Division of the United States Department of Justice under the
HSR Act, (b) will use its reasonable best efforts to obtain (and the Seller
will cause each of the Company and the Company Subsidiaries to use its
reasonable best efforts to obtain) an early termination of the applicable
waiting period, and (c) will make (and the Seller will cause each of the
Company and the Company Subsidiaries to make) any further filings pursuant

provided, however, that neither the Buyer nor any of its Affiliates shall be
obligated to agree (i) to divest any of their respective assets or any of the
assets being acquired under this Agreement or (ii) to any condition imposed by
any Governmental Authority that would adversely impact the respective
businesses of the Buyer or any of its Affiliates or that would otherwise
reduce the benefits to the Buyer or any of its Affiliates resulting from the
consummation of the transactions contemplated by this Agreement. The parties
shall consult with each other and keep the other parties informed of the
status of the matters referred to in this Section 6.4 and, except to the
extent confidential treatment has been given to any document filed with a
Governmental Authority pursuant to this Section 6.4, shall provide the other
party with copies of all such documents prepared on its behalf and all
correspondence relating thereto. Each party will bear its own costs and
expenses in connection with filings under the HSR Act.

          SECTION 6.5. Publicity. All general notices, releases, statements
and communications to employees, suppliers, distributors and customers of the
Company and each Company Subsidiary and to the general public and the press
relating to the transactions covered by this Agreement shall be made only at
such times and in such manner as may be agreed upon in advance between the
Buyer and the Seller; provided, however, that any party hereto shall be
entitled to make a public announcement of the foregoing if, in the opinion of
its legal counsel, such announcement is required to comply with Laws or any
listing agreement with any national securities exchange or inter-dealer
quotation system and if it first gives prior written notice to the other
parties hereto of its intention to make such public announcement and such
other parties are provided a reasonable opportunity for review prior to making
such public announcement.

          SECTION 6.6. Confidentiality. Notwithstanding any other provision of
this Agreement to the contrary, each party agrees that, unless and until the
transactions contemplated herein are consummated, it shall remain subject to
all of the terms and conditions of the Mutual Nondisclosure Agreement, dated
as of September 5, 2001 (the "Confidentiality Agreement"),


                                     -35-



between the Seller and EMCOR Group, Inc., the terms of which Confidentiality
Agreement are incorporated herein by reference; provided, however, that
notwithstanding the provisions of the Confidentiality Agreement and the
foregoing provisions of this Section 6.6, (a) each party shall keep
confidential in accordance with the terms of the Confidentiality Agreement all
Confidential Information that relates to the other party until the second
anniversary of the Closing Date and (b) the provisions of the Confidentiality
Agreement shall be waived as and to the extent necessary to permit public
announcements to the extent provided in Section 6.5. In the event that a party
is requested or required (by oral question or request for information or
documents in any legal proceeding, interrogatory, subpoena, civil
investigative demand, or similar process) to disclose any Confidential
Information, such party will notify the other party promptly of the request or
requirement so that such other party may seek an appropriate protective order
or waive compliance with the provisions of this Section 6.6. If, in the
absence of a protective order or the receipt of a waiver hereunder, the
disclosing party is, on the advice of counsel, compelled to disclose any
Confidential Information to any tribunal or else stand liable for contempt,
then such party may disclose the Confidential Information to the tribunal;
provided, however, that the disclosing party shall use its reasonable best
efforts to obtain, at the request of the non-disclosing party, an order or
other assurance that confidential treatment will be accorded to such portion
of the Confidential Information required to be disclosed as the non-disclosing
party shall designate. The foregoing provisions shall not apply to any
Confidential Information that is generally available to the public immediately
prior to the time of disclosure.

          SECTION 6.7. Taxes. Except as provided in this Agreement or as
required by Law, and except with regard to federal income Taxes and the net
income-based Taxes of any state that recognizes elections made under section
338(h)(10) of the Code (or an analogous provision of state law), without the
written consent of the Buyer, neither the Seller, the Company nor any of the
Company Subsidiaries shall make or change any Tax election, change any annual
Tax accounting period, change any method of Tax accounting, file any amended
Tax Return, enter into any closing agreement relating to any Tax, waive or
extend the statute of limitations in respect of Taxes, settle any Tax claim or
assessment or surrender any right to claim for a Tax refund, or change regular
independent accountants to the extent such action would have a Material
Adverse Effect on the Company or any Company Subsidiary Group. In addition,
neither any Affiliated Group (the common parent of which is the Seller) nor
any member of any such Affiliated Group may, except as required by Law,
undertake any of the foregoing actions without the written consent of the
Buyer to the extent such action would have a Material Adverse Effect on the
Company or any Company Subsidiary Group.

          SECTION 6.8. Exclusivity. The Seller will not, and will not cause or
permit any of the Company or the Company Subsidiaries to, (a) solicit,
initiate, or encourage the submission of any proposal or offer from any Person
relating to the acquisition of any capital stock or other voting securities,
or any substantial portion of the assets of, any of the Company and the
Company Subsidiaries (including any acquisition structured as a merger,
consolidation, or share exchange) or (b) participate in any discussions or
negotiations regarding, furnish any information with respect to, assist or
participate in, or facilitate in any other manner, any effort or attempt by
any Person to do or seek any of the foregoing. The Seller will not vote its
Interests in favor of any such acquisition structured as a merger,
consolidation, or share exchange. The Seller will


                                     -36-



notify the Buyer immediately if any Person makes any proposal, offer, inquiry,
or contact with respect to any of the foregoing.

          SECTION 6.9. Update. Each party hereto will promptly disclose to the
other in writing (a) any material information contained in its representations
and warranties and on the related schedules that is incomplete or no longer
correct or that, if known prior to the date of this Agreement, would have been
required to have been disclosed in such party's schedules to this Agreement
and (b) any casualty or other losses that are, individually or in the
aggregate, material to a Company Subsidiary Group arising between the date
hereof and the Closing Date regardless of whether such losses would have
resulted in a breach of a representation or warranty. None of the disclosure
pursuant to this Section 6.9 will be deemed to modify, amend or supplement the
representations and warranties of any party hereto or to prevent or cure any
misrepresentation, breach of warranty or breach of covenant.

          SECTION 6.10. Financial Statements. Prior to the Closing Date, the
Seller (a) shall use its best efforts to cause to be delivered to the Buyer
the audited consolidated balance sheets of the Company as of the years ended

income, shareholders' equity and cash flows of the Company for the years then
ended, together with the notes to such financial statements and the reports
thereon of the Seller's accountants (collectively, the "Audited Financial
Statements"), prepared in accordance with GAAP applied on a basis consistent
with the Seller's past practice and prepared on the same basis and using the
same accounting principles, policies and practices used in preparing the
Audited Financial Statements and (b) shall use its reasonable best efforts to
obtain all consents and authorizations from its accountants necessary to
permit the Buyer to incorporate the Audited Financial Statements in preparing
any of the Buyer's filings under the Exchange Act.

          SECTION 6.11. Termination of Affiliate Transactions; Release of
Obligations. (a) Except as may be identified for preservation on Schedule
5.18, the Seller shall terminate, or cause its Affiliates (including the
Company and the Company Subsidiaries) to terminate, all transactions among the
Company or any Company Subsidiary on the one hand and the Seller or any of its
Affiliates (excluding the Company or the Company Subsidiaries) on the other,
including without limitation transactions identified and not noted for
preservation on Schedule 5.18.

          (b) At or prior to the Closing Date, the Seller shall release, or
cause its Affiliates (including any of its Subsidiaries not being transferred
to the Buyer pursuant to this Agreement (the "Retained Subsidiaries"), but
excluding the Company and the Company Subsidiaries) to release, the Company
and each of the Company Subsidiaries from any and all amounts owing by the
Company or any Company Subsidiary on the one hand to the Seller or any of its
Affiliates (excluding the Company or the Company Subsidiaries) on the other,
including without limitation those amounts owing identified on Schedule 5.18,
except with respect to amounts owed pursuant to a transaction that has been
identified for preservation on Schedule 5.18. Immediately following the
Closing Date, the Buyer shall release, or cause the Company or any Company
Subsidiary to release, the Seller and any of its Affiliates (including
Retained Subsidiaries) from any and all amounts owing by the Seller or any of
its Affiliates (including Retained Subsidiaries) on the one hand to the
Company or any Company Subsidiary on the other, including without limitation
those amounts owing identified on Schedule 5.18, except with respect


                                     -37-


to amounts owed pursuant to a transaction that has been identified for
preservation on Schedule 5.18.

confirmation from Zurich American Insurance Company ("Zurich") that Zurich and
its Affiliates will not seek reimbursement from any of the Company or the
Company Subsidiaries for any deductible amounts under the Seller's insurance
policies with Zurich.

          SECTION 6.13. Bonuses. Prior to the Closing Date, the Seller shall
have paid any bonuses payable to the president of each Company Subsidiary
pursuant to the Comfort Systems USA 2001 President's Bonus Plan in respect of
the fiscal year ended December 31, 2001.

          SECTION 6.14. Certain Real Property Matters. (a) Prior to the
Closing Date, the Seller shall have purchased for book value as of December
31, 2001, the property described on Schedule 5.9(a) hereto of Border
Electrical Co., L.P. ("Border Electric"), located at 10855 Pellicano, El Paso,
Texas without recourse to the Buyer, Border Electric or any of their
Affiliates.

          (b) Prior to the Closing Date, the Seller shall, at its own expense,
use its best efforts to cause Maximum Refrigeration & Air Conditioning Corp.
(formerly known as CS24 Acquisition Corp.), a Company Subsidiary and the
tenant under that certain lease agreement, dated June 30, 1998, by James
Olympios, as landlord, for the space located at 1310 Central Avenue, Hillside,
New Jersey ("Hillside lease"), described on Schedule 5.9(b) hereto, (i) to
terminate the Hillside lease with the consent of the landlord and (ii) to be
released from any and all obligations thereunder. In the event the Seller has
not obtained such termination, landlord's consent and release prior to the
Closing Date, at the Buyer's option, the Seller shall assume the obligations
under the Hillside lease or shall reduce the Purchase Price by $100,000. 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).

                                 ARTICLE VII
                            POST-CLOSING COVENANTS

          SECTION 7.1. General. In case at any time after the Closing any
further action is necessary or desirable to carry out the purposes of this
Agreement, each party will take such further action (including the execution
and delivery of such further instruments and documents) as the other party
reasonably may request, all at the sole cost and expense of the requesting
party


                                     -38-



(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.

          SECTION 7.2. Non-Solicitation. During the period from and including
the Closing Date to but excluding the second anniversary of the Closing Date,
the Seller shall not, and shall not permit its Subsidiaries to, solicit for
employment or hire any employee of the Company or the Company Subsidiaries to
work for the Seller or any of its Subsidiaries; provided that this Section 7.2
shall not prohibit the Seller or any of its Subsidiaries from hiring an
individual who responds to general media advertisements not directed at the
employees of the Company and the Company Subsidiaries.

          SECTION 7.3. Employee Benefits. (a) As of the Closing Date, the
Seller shall cause the account balance of each Company Employee, who is not a
highly compensated employee as defined in section 414(q) of the Code, in each

fully vested.

          (b) As of the Closing Date, the Seller shall transfer to the Buyer
the individual health care reimbursement and dependent care reimbursement
account balances under the Seller's Health Care Reimbursement Account and
Dependent Care Reimbursement Account plans (the "Reimbursement Account Plans")
for each participant who is a Company Employee. 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. Notwithstanding the foregoing, nothing herein shall require the
Buyer to continue or maintain the EMCOR Group, Inc. Welfare Plan.

          SECTION 7.4. WARN Act. The Buyer shall be responsible for, and shall
indemnify the Seller 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 after the Closing, but only to the extent it arises
solely from actions taken by the Buyer after the Closing. 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.

          SECTION 7.5. Litigation Support. In the event and for so long as any
party actively is contesting or defending against any Action in connection
with (i) any transaction


                                     -39-



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 Seller will refer all customer inquiries relating to the
businesses of the Company and the Company Subsidiaries to the Buyer from and
after the Closing.

          SECTION 7.7. Third Party Indemnification. To the extent that any
Company Subsidiary does not have direct contractual indemnification rights
against a third party under the Predecessor Acquisition Agreements, the Seller
will pursue any and all such indemnification rights on behalf of the Buyer at
the request of the Buyer.

          SECTION 7.8. Assumed Obligations. Effective as of the Closing Date,
the Buyer hereby assumes all the Assumed Obligations.

          SECTION 7.9. Minute Books. Promptly after the Closing Date, the
Seller shall deliver to the Buyer all the minute books of the Company and the
Company Subsidiaries and their predecessors, including all stock registers,
corporate seals and related materials and all other books and records
pertaining to the respective businesses of the Company Subsidiaries.

          SECTION 7.10. Use of Name. The Seller hereby grants to the Buyer and
its Subsidiaries a non-exclusive license to use the names "Comfort Systems
USA, Inc.", "Comfort Systems" and any derivative or other names currently used
by any of the Company Subsidiaries that are not owned by such Company
Subsidiaries (the "Comfort Names") until the first anniversary of the Closing
Date, as or as part of any trade name, corporate name, domain name, trademark,
service mark, logo, design or other source indicator appearing on the assets,
products or materials owned or used by the Company Subsidiaries prior to the
Closing Date. 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. The Buyer shall use its commercially reasonable efforts to obtain
all credit approvals that are necessary in connection with the assignment of
any vehicle leases. To the extent any such lease cannot be transferred by its
terms, the Seller at its own expense shall purchase such vehicle and lease
such vehicle to the applicable Company Subsidiary on terms that are identical
to the original lease.

          SECTION 7.12. Audit. From and after the Closing Date, the Seller
agrees that (a) it shall cooperate with, and provide reasonable access to, the
Buyer in the planning and execution of any audit of the Company and the
Company Subsidiaries that may be required after the Closing under the Exchange
Act, and (b) shall use its reasonable best efforts to obtain all consents and
authorizations from its accountants necessary to permit the Buyer to
incorporate such financial statements in preparing any of the Buyer's filings
under the Exchange Act.

          SECTION 7.13. Tax Treatment of the Company. The Buyer will not take
any action (including the filing of an IRS Form 8832 on which the Buyer elects
to have the Company treated as a corporation) that could cause the Company to
be characterized for federal or state income tax purposes as a corporation
during any period (or portion thereof) ending on or prior to the Closing Date.

          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 period of six months after the Closing Date, the Seller shall not, and
shall cause each of its Affiliates not to, solicit the business of any AMN
Client.

          (d) For a period of six months after the Closing Date, the Company
Subsidiary, Kuempel Service, Inc. ("Kuempel") shall sublet to the NSO the
premises in Cincinnati, Ohio presently sublet to the NSO by Kuempel. Such
premises shall be sublet at the rate of $10,213.00 per month, on terms and
conditions contained in a draft of sublease initialed by the parties on the
date hereof and to be executed on the Closing Date.

          SECTION 7.16. Continuation of Insurance Coverage. 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.

          SECTION 7.18. Pre-Closing Financial Reporting. Within 40 days after
the end of the quarter during which the Closing occurs, the Buyer will cause
each Company Subsidiary to prepare and send to the Seller the financial
statements of such Company Subsidiary, in substantially the form heretofore
prepared by the Company Subsidiaries for the Seller, for the period January 1,
2002 to the Closing Date.

          SECTION 7.19. Transfer of Domain Names. As soon as practicable, but
in any event no later than 45 days after the Closing Date, the Seller shall
transfer to each Company Subsidiary all right, title and interest in the
domain names that are owned by the Seller relating to


                                     -43-



the business of each respective Company Subsidiary, including all
registrations, reservations and applications relating thereto (including any
of the foregoing at new gTLD registrars and registries), except domain names
that incorporate the words, "Comfort", "Comfort Systems" or "CSUSA" and domain
names that are applicable to all the Retained Subsidiaries. The Seller agrees
not to apply to register or reserve any additional domain names that are the
same as, or similar to, such domain names at any time. At the reasonable
request of the Buyer, the Company or any Company Subsidiary, the Seller shall
take all actions and execute all documents necessary or desirable to
facilitate the above transfer.

                                 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.

          (a) With respect to the Seller's sale of the Interests to the Buyer
and, indirectly, the sale of all of the outstanding equity interests (the
"Shares") of each of the Company Subsidiaries to the Buyer, the Seller and the
Buyer shall jointly make in respect of each Company Subsidiary a timely and
irrevocable election under section 338(h)(10) of the Code (and any
corresponding election under state and local Tax law) (collectively, the
"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.

          (c) As soon as practicable after the Closing Date, the Seller and
the Buyer shall agree upon (i) the allocation of the Purchase Price among the
assets of the Company (the "Purchase Price Allocation") and (ii) the fair
market value of the assets of each Company Subsidiary and the allocation of
the deemed sales price of the assets of each such Company Subsidiary resulting
from the Elections (as required pursuant to section 338(h)(10) of the Code and
the regulations promulgated thereunder and any comparable provisions of state
or local law, as appropriate) among such assets (the "Section 338 Allocation"
and, collectively with the Purchase Price Allocation, the "Allocations"). 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.

          SECTION 8.10. Tax Sharing Agreements. Any tax sharing agreement
between the Seller and any of the Company and the Company Subsidiaries is
terminated as of the Closing Date and will have no further effect for any
taxable year (whether the current year, a future year, or a past year).

                              REMEDIES FOR BREACH

          SECTION 10.1. Limitation on and Survival of Representations and
Warranties.

          (a) All representations and warranties contained in this Agreement,
or in any agreements or instruments executed in connection herewith or
delivered pursuant hereto, shall survive the Closing for a period of two years
beginning on the Closing Date, but not longer; provided, however, that the
representations and warranties contained in Section 5.15 (Employee Benefits),
Section 5.17 (Taxes) and Section 5.20 (Environmental Matters) shall survive
until the expiration of the applicable statute of limitations for the matter
giving rise to a claim hereunder and the representation and warranties
contained in Section 3.1 (Organization of Seller; Ownership of the Interests),
Section 5.1 (Organization; Capitalization of the Company) and Section 5.3
(Subsidiaries) shall survive indefinitely. In order to seek a remedy pursuant

set forth in Section 10.1 and Section 10.4, the Seller hereby agrees to
indemnify and hold the Buyer and its directors, officers, employees,
stockholders and Affiliates (collectively, the "Buyer Indemnified Parties")
harmless from and against any and all Losses imposed upon or incurred by the
Buyer Indemnified Party (any of such Losses by Buyer Indemnified Parties, a
"Buyer 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 (except with respect to
          Section 5.17 which is provided for pursuant to Section 8.1(a)) made
          by the Seller in this Agreement or in any certificate delivered
          pursuant hereto; provided, however, 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

                                     -53-



          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. No waiver hereunder
shall be deemed to extend to any prior or subsequent default,
misrepresentation or breach or affect in any way any rights arising as a
result of such prior or subsequent occurrence.

          SECTION 12.2. Expenses. Whether or not the transactions contemplated
by this Agreement are consummated, each of the parties hereto shall pay the
fees and expenses of their respective counsel, investment bankers, financial
advisors, accountants and other experts and the other expenses incident to the
negotiation and preparation of this Agreement and the consummation of the
transactions contemplated hereby. The Seller agrees that none of the Company
or the Company Subsidiaries has borne or will bear the Seller's costs and
expenses (including any of its legal fees and expenses) in connection with
this Agreement or any of the transactions contemplated hereby, except in
connection with the conduct of due diligence investigations by the Buyer prior

          (b) Each of the parties submits to the jurisdiction of any state or
federal court sitting in Delaware, in any action or proceeding arising out of
or relating to this Agreement and agrees that all claims in respect of the
action or proceeding may be heard and determined in any such court. Each party
also agrees not to bring any action or proceeding arising out of or relating
to this Agreement in any other court. Each of the parties waives any defense
of inconvenient forum to the maintenance of any action or proceeding so
brought and waives any bond, surety, or other security that might be required
of any other party with respect thereto. Each party appoints CT Corporation
(the "Process Agent") as its agent to receive on its behalf service of copies
of the summons and complaint and any other process that might be served in the
action or proceeding. Any party may make service on any other party by sending
or delivering a copy of the process (i) to the party to be served at the
address and in the manner provided for the giving of notices in Section 12.5
or (ii) to the party to be served in care of the Process Agent at the address
and in the manner provided for the giving of notices in Section 12.5. Nothing
in this Section 12.3, however, shall affect the right of any party to serve
legal process in any other manner permitted by law or at equity. Each party
agrees that a final judgment in any action or proceeding so brought shall be
conclusive and may be enforced by suit on the judgment or in any other manner
provided by law or at equity.

          SECTION 12.4. Assignment. This Agreement and each party's rights
hereunder may not be assigned without the prior written consent of the other
party, except that the Buyer may (a) assign any or all of its rights and
obligations hereunder to one or more Affiliates and (b) designate one or more
of its Affiliates to perform its obligations hereunder; provided, however,
that in any or all of such cases the Buyer nonetheless shall remain
responsible for the performance of all of its obligations hereunder. Subject
to the preceding sentence, this Agreement shall be binding upon the parties
hereto and their respective successors and assigns.

          SECTION 12.5. Notices. All communications, notices and disclosures
required or permitted by this Agreement shall be in writing and shall be

          SECTION 12.6. Amendment and Waiver. No amendment of any provision of
this Agreement shall be valid unless the same shall be in writing and signed
by the Buyer and the Seller. No waiver by any party of any default,
misrepresentation or breach of warranty or covenant hereunder, whether

occurrence.

only and shall not affect in any way the meaning or interpretation of this
Agreement.

          SECTION 12.8. Specific Performance. Each party acknowledges and
agrees that the other party would be damaged irreparably in the event any of
the provisions of this Agreement are not performed in accordance with their
specific terms or otherwise are breached. Accordingly, each party agrees that
the other party shall be entitled to an injunction or injunctions to prevent
breaches of the provisions of this Agreement and to enforce specifically this
Agreement and the terms and provisions hereof in any action instituted in any
court of the United States or any state thereof having jurisdiction over the

                                                                     EXHIBIT A

                                    FORM OF
                               ESCROW AGREEMENT

          This Escrow Agreement, dated as of March [__], 2002 (this
"Agreement"), is made and entered into by and among Comfort Systems USA, Inc.,
a Delaware corporation ("Seller"), EMCOR-CSI Holding Co., a Delaware
corporation ("Buyer"), and Bank One, National Association, as escrow agent
(the "Agent").

                                  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. Definitions. Capitalized terms not otherwise defined herein shall
have the meanings set forth in the Purchase Agreement.

          2. Appointment of Agent. The Agent is hereby appointed by each of
the Seller and the Buyer to act as escrow agent hereunder. The Agent hereby
accepts such appointment and agrees to hold and administer the Escrow Account
(as defined below) in accordance with the terms and subject to the conditions
set forth herein.

          3. Establishment of the Escrow Account. On the Closing Date, the
Adjustment Escrow Amount and the Indemnification Escrow Amount (collectively,
the "Escrow Funds") shall be deposited with the Agent in a separate escrow
account (the "Escrow Account") as set forth in the Purchase Agreement. The
parties hereto agree that the Agent is serving solely as escrow agent and does
not, and will not, own or have any interest in the Escrow Funds, having




only possession of the Escrow Funds. The parties hereto intend that the Escrow
Account be treated for tax purposes as a grantor trust to which the
[Seller/Buyer] has transferred the Escrow Funds. Accordingly, the parties
hereto agree that for tax purposes they will treat the [Seller/Buyer] as the
owner of the Escrow Funds.

          4. Investment of Escrow Funds. During the term of this Agreement,
all or any portion of the Escrow Funds shall be invested and reinvested by the
Agent, as directed in writing by the [Seller/Buyer], in (a) obligations that
(i) are issued by the United States government or any agency or
instrumentality thereof and (ii) have a maturity of not more than three
months; (b) obligations that (i) are issued by any state or municipality of
the United States, (ii) have a maturity of not more than three months and
(iii) have one of the two highest rating grades by Moody's Investor Service,
Inc. ("Moody's") or Standard & Poor's, a division of The McGraw Hill
Companies, Inc. ("S&P"), (c) certificates of deposit that (i) are issued by
any bank or trust company that has (A) debt obligation ratings in one of the
two highest rating grades by Moody's or S&P and (B) a combined capital and
surplus and undivided profits of not less than $100,000,000 and (ii) have a
maturity of not more than three months; or (d) money market rate accounts with
the Agent. The Agent shall liquidate all or any portion of the investments
made with the Escrow Funds at such time and in such manner as the
[Seller/Buyer] may direct in writing or, in the absence of any such direction,
as the Agent, in its sole and absolute discretion, may elect, in each case in
order to convert such investments into cash for application and distribution
in accordance with this Agreement.

          5. Duration; Release of Escrow.

          (a) Release of Adjustment Escrow Amount

               (i) Except as provided in clauses (ii) and (iii) of this
          Section 5(a), the Agent shall hold the Adjustment Escrow Amount
          until the termination of the Adjustment Security Period.

               (ii) If the Agent shall be furnished with a copy of a
          determination pursuant to Section 2.5(d) of the Purchase Agreement
          (a "Determination") stating that the Independent Accountants have
          determined that (A) 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 and (B) 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 the Purchase Agreement, shall be
          final, binding and conclusive on the Seller and the Buyer and shall
          be used in computing the Adjustment Amount, then the Agent shall
          subtract such Closing Net Asset Value from [$65,900,000](1) to
          determine the Adjustment Amount. If the Adjustment Amount is
          positive, then the Agent shall promptly, but in no event more than
          five Business Days after receipt by the Agent of the Determination,
          reduce the Adjustment Escrow Amount by an amount equal to the lesser
          of (1) the Adjustment Amount, together

_______________

(1)  This number may be adjusted pursuant to Section 11.1(f) of the Purchase
     Agreement prior to execution of this Escrow Agreement.


                                      2


          with interest thereon at the rate of 6% per annum from the Closing
          Date until the date on which the Adjustment Amount is paid, and (2)
          the Adjustment Escrow Amount, and pay such amount by wire transfer
          of immediately available funds to an account designated in writing
          by the Buyer. If the Adjustment Amount is negative, then the Agent
          shall promptly, but in no event more than five Business Days after
          receipt by the Agent of the Determination, release to the Seller the
          Adjustment Escrow Amount by wire transfer of immediately available
          funds to an account designated in writing by the Seller.

               (iii) If the Agent receives a notice of agreement ("Notice of
          Agreement") that is executed by the Buyer and the Seller with
          respect to the Adjustment Amount and directing the Agent to pay an
          amount stated therein to the Buyer or the Seller, as specified
          therein, then the Agent shall promptly, but in no event more than
          five Business Days after receipt by the Agent of such Notice of
          Agreement, reduce the Adjustment Escrow Amount by an amount equal to
          the lesser of (A) the amount stated in such Notice of Agreement and
          (B) the Adjustment Escrow Amount, and pay such amount by wire
          transfer of immediately available funds to an account designated in
          writing by the Buyer or the Seller, as the case may be.

               (iv) At the end of the Adjustment Security Period, the Agent
          shall release to the Seller any remaining Adjustment Escrow Amount
          by wire transfer of immediately available funds to an account
          designated in writing by the Seller.

               (b) Release of Indemnification Escrow Amount

               (i) Except as provided in clauses (ii) through (iv) of this
          Section 5(b), the Agent shall hold the Indemnification Escrow Amount
          until the termination of the Indemnification Security Period.

               (ii) If the Agent shall be furnished by the Buyer with a copy
          of an award (an "Award") in an action against the Seller by the
          Buyer made by any arbitrator, mediator or court of competent
          jurisdiction resulting from a claim for indemnification by the Buyer
          pursuant to Article X of the Purchase Agreement, then the Agent
          shall promptly, but in no event more than five Business Days after
          receipt by the Agent of such Award, reduce the Indemnification
          Escrow Amount by an amount equal to the lesser of (A) the amount
          stated in the Award and (B) the Indemnification Escrow Amount, and
          pay such amount by wire transfer of immediately available funds to
          an account designated in writing by the Buyer.

               (iii) If the Agent receives a Notice of Agreement that is
          executed by the Buyer and the Seller with respect to the payment of
          a claim for indemnification by the Buyer pursuant to Article X of
          the Purchase Agreement, then the Agent shall promptly, but in no
          event more than five Business Days after receipt by the Agent of
          such Notice of Agreement, reduce the Indemnification Escrow Amount
          by an amount equal to the lesser of (A) the amount stated in such
          Notice of Agreement and (B) the Indemnification Escrow Amount, and
          pay such amount by wire transfer of immediately available funds to
          an account designated in writing by the Buyer.

                                      3


               (iv) At the end of the Indemnification Security Period, the
          Agent shall release to the Seller any remaining Indemnification
          Escrow Amount that is not necessary to satisfy any amounts with
          respect to any unresolved claim for indemnification under Article X
          of the Purchase Agreement made by the Buyer prior to the end of the
          Indemnification Security Period.

loss to the Buyer or the Seller. The Agent may consult with counsel of its own
choice and shall have full and complete authorization and protection for any
action taken or omitted by it hereunder in good faith and in accordance with
the opinion or advice of such counsel.

indemnify the Agent for and to hold it harmless against any loss, liability or
expense arising out of or in connection with this Agreement and the carrying
out its duties hereunder, including the costs and expenses of defending itself

guilty of gross negligence or willful misconduct. Anything in this Agreement
to the contrary notwithstanding, in no event shall the Agent be liable for
special, indirect or consequential loss or damage of any kind whatsoever

advised of the likelihood of such loss or damage and regardless of the form of
action.


                                      4


          (e) In the event the Agent is uncertain as to its duties or rights
hereunder or receives instructions, claims or demands from any party hereto
that, in its opinion, conflict with any of the provisions of this Agreement,
it shall be entitled to refrain from taking any action and its sole obligation
shall be to keep safely all property held in the Escrow Account until it is
directed otherwise by a final order or judgment of a court of competent
jurisdiction.

          (f) This Agreement shall not be deemed to create a fiduciary
relationship between any of the parties hereto under state or federal law.

termination of this Agreement, a resignation of the Agent and the release of
all property and the payment of any and all amounts hereunder.

          7. Agent Expenses. All fees and expenses (including reasonable
attorneys' fees) of the Agent incurred in the course of performing its

together shall constitute one and the same instrument.

          (d) Entire Agreement. This Agreement with respect to the Agent, the
Buyer and the Seller and this Agreement and the Purchase Agreement with
respect to the Buyer and the Seller constitute the entire understanding and
agreement of the parties hereto with respect

                                      6


to the subject matter hereof and supersede all prior agreements and
understandings, written or oral, between the parties hereto with respect to
the subject matter hereof.

          (e) Waivers. No waiver by any party hereto of any condition or of
any breach of any provision of this Agreement shall be effective unless in
writing and signed by a duly authorized representative of the party granting
such waiver. No waiver by any party of any such condition or breach in any one

          (h) Resignation of Agent. The Agent shall have the right to resign
upon 30 days written notice to the Buyer and the Seller. In the event of such
resignation, with the consent of the Buyer, which consent shall not

by delivering to the Agent a written notice of such appointment. Upon receipt
of such notice, the Agent shall deliver to the designated successor agent all
property held hereunder and shall thereupon be released and discharged from
any and all further responsibilities whatsoever under this Agreement;

earned prior to such time or the benefits of Section 6 hereof. If no successor
agent shall have been designated by the date specified in the Agent's notice,
all obligations of the Agent hereunder shall nevertheless cease and terminate.
Its sole responsibility thereafter shall be to keep safely all property then
held by it and to deliver the same to a person designated by the other parties
hereto or in accordance with the direction of a final order or judgment of a
court of competent jurisdiction.

                        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

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

hereto.

          (j) "Seller Provided Services" shall have the meaning set forth in
Section 2.1.

          (k) "Services" shall mean, collectively, the Buyer Provided Services

                                   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

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

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

the other party by a Notice given in accordance with the provisions of this
Section 7.3. Each Notice shall be deemed given and effective upon receipt (or
refusal of receipt).

          7.4 Entire Agreement. Except for those matters provided for in the
Purchase Agreement, this Services Agreement and the Schedules attached hereto
contain every obligation and understanding between the parties relating to the
subject matter hereof and merge all prior discussions, negotiations and
agreement, if any, between the parties with respect to the subject matter
hereof, and none of the parties shall be bound by any representations,
warranties, covenants or other understandings with respect to the subject
matter hereof, except as expressly provided herein or in the Purchase
Agreement.

          7.5 Waiver and Amendment. Any representation, warranty, covenant,
term or condition of this Services Agreement which may legally be waived, may
be waived, or the time of performance thereof extended, at any time by the
party hereto entitled to the benefit thereof, and any term, condition or
covenant hereto may be amended by the parties hereto at any time. Any such
waiver, extension or amendment shall be evidenced by an instrument in writing
executed on behalf of the appropriate party by a Person who has been
authorized by such party to execute waivers, extensions or amendments on its
behalf. No waiver by any party hereto, whether express or implied, of its
rights under any provision of this Services Agreement shall constitute a
waiver of such party's rights under such provisions at any other time or a
waiver of such party's rights under any other provision of this Services
Agreement. No failure by any party hereto to take any action against any
breach of this Services Agreement or default by the other party shall
constitute a waiver of such party's right to enforce any provision of this
Services Agreement or to take action against such breach or default or any
subsequent breach or default by such other party.

          7.6 Severability. In the event that any one or more of the
provisions contained in this Services Agreement shall be declared invalid,
void or unenforceable, the remainder of the provisions of this Services
Agreement shall remain in full force and effect, and such invalid, void or
unenforceable provision shall be interpreted as closely as possible to the
manner in which it was written.

          7.7 Governing Law, Jurisdiction. This Services Agreement shall be
interpreted and construed in accordance with the laws of the State of New
York. Except where equitable relief is sought, neither party shall commence
any proceeding against the other party under this Services Agreement unless
and until the parties shall have attempted in good faith to settle the
underlying dispute through negotiation or mediation for a period of not less
than 30 days. Subject to the preceding sentence, each party agrees that any
action, proceeding or claim it commences against the other party pursuant to
this Services Agreement shall be brought in any state or federal courts
sitting in Delaware. Each party irrevocably waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the
laying of the venue of any such suit, action or proceeding brought in any such
court, any claim that any such suit, action or proceeding brought in such a
court has been sought in an inconvenient forum and the right to object, with
respect to any such suit, action or proceeding brought in any such court, that
such court does not have jurisdiction over such party. 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. Each party agrees that a final non-appealable judgment in any such suit,
action or proceeding brought in such a court shall be conclusive and binding.

          7.8 Counterpart Execution. This Services Agreement may be executed
in counterparts with the same effect as if all of the parties had signed the
same document. Such counterparts shall be construed together and shall
constitute one and the same instrument, notwithstanding that all of the
parties are not signatories to the original or the same instrument, or that
signature pages from different counterparts are combined. 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.
Notwithstanding the foregoing, either party may assign any of its rights and
obligations under this Services Agreement, in whole or in part, to one or more
wholly owned Subsidiaries of such party. Any party so assigning this Services
Agreement shall remain fully liable to the other party for the performance by
any assignee of any obligation of such party so assigned. Any purported
assignment in violation of this Section 7.9 shall be void.

          7.10 Disclaimer. Except as expressly set forth herein, no party
makes any representations or warranties in respect of the services provided
under this Services Agreement, express or implied.

          7.11 No Third Party Beneficiary. Nothing expressed or implied in
this Services Agreement is intended, or shall be construed, to confer upon or
give any Person other than the parties hereto, their respective successors and
permitted assigns and the indemnitees, any rights or remedies under or by
reason of this Services Agreement.

          7.12 Headings and Interpretation. Titles and headings to articles
and sections herein and titles to the Schedules are inserted for convenience
of reference only and are not intended to be a part of or to affect the
meaning or interpretation of this Services Agreement. The Schedules referred
to herein shall be construed with and as an integral part of this Services
Agreement to the same extent as if they were set forth verbatim herein.

          7.13 Survival. Notwithstanding anything to the contrary herein, the
rights and obligations of the parties under this Service Agreement which by
their nature would continue beyond the termination of this Services Agreement,
including, but not limited to, the rights and obligations set forth in
Sections 3.3, 6.1, 7.1, 7.3, 7.7 and 7.14, shall survive termination of this
Services Agreement.

          7.14 Confidentiality. (a) Notwithstanding any other provision of
this Services Agreement to the contrary, each party agrees that, throughout
the Term, such party shall remain subject to (i) all of the terms and
conditions of the Mutual Nondisclosure Agreement, dated as of

                                      8

to the Buyer's business shall be treated by Seller as Confidential Information
pursuant to the terms of the Purchase Agreement and the Confidentiality
Agreement. In connection with the Seller Provided Services described on

the Company or any Company Subsidiary without the written permission of the

          days notice before disconnecting any individual Company Subsidiary,

        Seller Provided Services: Company Subsidiary Checking Accounts


         For a period of up to 30 days after the Closing Date, Seller shall
maintain existing Bank One N.A. controlled disbursement accounts for each
Company Subsidiary, excluding Shambaugh & Son, Inc., F&G Mechanical, Inc. and
The Fagan Company (after such exclusions, the "Maintained Accounts"), all as
in effect prior to the Closing Date. Buyer will use its best efforts to
replace each of the Maintained Accounts on the earliest date that is
reasonably possible. With respect to the Maintained Accounts, by not later
than 5:00 p.m. (Central Time) of each business day following the day that a
Company Subsidiary issues one or more checks against its checking account,
Buyer shall report to Seller, by way of e-mail, that such checks have been
issued. The report shall also include, with respect to each such check, the
account number, amount, check number and the issuer thereof. Before the close
of the next banking day thereafter, Buyer shall remit in immediately available
funds by wire transfer to the account designated by Seller the aggregate
amount represented by such checks. Seller shall not be required to maintain
any Maintained Account for any Company Subsidiary as to which it does not
receive either timely reports or timely reimbursement on more than two
occasions. Reimbursement shall not be subject to counterclaim or set-off, and
Buyer shall pay Seller interest at the rate of 1% per day for late
reimbursements, and interest at the rate of 1.5% per day for reimbursements

         For a period of five months from the Closing Date, Buyer shall cause
Shambaugh & Son, Inc. ("S&S") to continue to manage, direct and administer the
existing national purchasing program of Seller to the extent required (a) to
obtain rebates for purchases made in 2001 by Seller and its Subsidiaries
(including Company Subsidiaries) and (b) to effect purchases in 2002 (through
the Closing Date), all in a manner consistent with Seller's and S&S's
practices prior to the Closing Date. Buyer shall also permit Seller to make
reasonable inquiries of Joe Jackson of S&S for the period from the Closing
Date through December 31, 2002 regarding the establishment and operation of a
national purchasing program, provided that such inquiries do not unduly
interfere with his duties to S&S and Buyer. In addition, Seller will pay to
Joe Jackson a bonus equal to the sum of (i) 1.5% of rebate cash collected with
respect to 2001 purchasing contracts in excess of $3 million and up to $4
million and (ii) 3% of rebate cash collected with respect to 2001 purchasing
contracts in excess of $4 million.

         The fee for the foregoing services shall be $21,000 per month for the
period from the Closing Date to five months thereafter and, in the event such
services commence on a day other than the first day of a month and end on a
day other than the last day of a month, such monthly fees shall be prorated.
