ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

      On February 12, 1998, the Registrant acquired F&G Mechanical Corporation
and Meadowlands Fire Protection Corp. (together, the "Businesses Acquired"),
which are engaged in the mechanical contracting business, primarily relating to
heating, ventilation, air conditioning and fire suppression sprinklers. The
consideration for the acquisitions consisted of an aggregate of 1,432,434 shares
of the common stock of the Registrant and approximately $7.5 million in cash.
The consideration paid by the Registrant in the acquisitions, the cash portion
of which constituted borrowing under the Company's credit line, was determined
through arm's length negotiations between representatives of the Registrant and
the Businesses Acquired.

      Prior to the transactions, the Businesses Acquired employed vehicles,
equipment and other miscellaneous personal property in the operation of
mechanical contracting businesses, and the Registrant intends that each business
will continue such activities.

ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS

     (A)  FINANCIAL STATEMENTS OF BUSINESSES ACQUIRED

         The Registrant believes that it is impractical to provide financial
         statements of the Businesses Acquired on the date of this filing, and
         will, if required, file such financial statements when available but
         not later than sixty (60) days after the date on which this Current
         Report on Form 8-K must be filed.

     (B)  PRO FORMA FINANCIAL INFORMATION

         The Registrant believes that it is impractical to provide pro forma
         financial information reflecting the Registrant's acquisitions, the
         Registrant will, if required, file such financial information when
         available but not later than sixty (60) days after the date on which
         this Current Report on Form 8-K must be filed.

     (C)  EXHIBITS

F&G MECHANICAL CORPORATION, a New Jersey corporation (the "Company"), and
SALVATORE FICHERA and SALVATORE P. GIARDINA (collectively, the "Stockholders").

      WHEREAS, the Board of Directors of each of CSI and the Company deems it
advisable and in the best interests of such corporation and its stockholders
that the Company merge with and into CSI pursuant to this Agreement and the
applicable provisions of the laws of the State of Delaware and the State of
Incorporation (as defined below); and

      WHEREAS, the Board of Directors of each of CSI and the Company has
approved and adopted this Agreement as a plan of reorganization under Section
368 of the Internal Revenue Code of 1986, as amended (the "Code");

      NOW, THEREFORE, in consideration of the premises and of the mutual
agreements, representations, warranties, provisions and covenants herein
contained, the parties hereto hereby agree as follows:

1.  THE MERGER

      1.1. THE MERGER. On the terms and subject to the conditions of this
Agreement, at the Effective Time (as defined below), the Company shall be merged
with and into CSI (the "Merger") and the separate existence of the Company shall
cease, all in accordance with the provisions of the General Corporation Law of
the State of Delaware (the "DGCL") and the law of the State of Incorporation.
CSI shall be the surviving corporation in the Merger and is sometimes
hereinafter called the "Surviving Corporation".

      1.2. EFFECTIVE TIME. The Merger shall become effective at such time (the
"Effective Time") as certificates of merger, in a form appropriate for filing,
are filed with the Secretaries of State (or other appropriate authorities) of
the State of Delaware and the State of Incorporation (the "Merger Filings"). The
Merger Filings shall be made simultaneously with or as soon as practicable after
the Closing (as defined below).

      1.3. CERTIFICATE OF INCORPORATION, BY-LAWS AND BOARD OF DIRECTORS OF
SURVIVING CORPORATION. At the Effective Time:

            (i) the Certificate of Incorporation of CSI then in effect shall be
      the Certificate of Incorporation of the Surviving Corporation until it
      shall thereafter be changed as provided by law;

                                    -1-

            (ii) the By-laws of CSI then in effect shall be the By-laws of the
      Surviving Corporation until they shall thereafter be duly amended;

            (iii) the Board of Directors of CSI immediately prior to the
      Effective Time shall be the Board of Directors of the Surviving
      Corporation, and shall serve as such until their resignation or
      replacement in accordance with the provisions of the laws of the State of
      Delaware and of the Certificate of Incorporation and By-laws of the
      Surviving Corporation; and

            (iv) the officers of CSI immediately prior to the Effective Time
      shall continue as the officers of the Surviving Corporation in the same
      capacity or capacities, each of such officers to serve, subject to the
      provisions of the Certificate of Incorporation and By-laws of the
      Surviving Corporation, until his or her successor is duly elected and
      qualified.

      1.4. EFFECT OF MERGER. At the Effective Time, the effect of the Merger
shall be as provided in the DGCL and the law of the State of Incorporation.
Except as herein specifically set forth, the identity, existence, purposes,
powers, objects, franchises, privileges, rights and immunities of CSI shall
continue unaffected and unimpaired by the Merger and the corporate franchises,
existence and rights of the Company shall be merged with and into CSI, and CSI,
as the Surviving Corporation, shall be fully vested therewith. At the Effective
Time, the separate existence of the Company shall cease and, in accordance with
the terms of this Agreement, the Surviving Corporation shall possess all the
rights, privileges, immunities and franchises, of a public, as well as of a
private, nature, and all property, real, personal and mixed, and all debts due
on whatever account, including subscriptions to shares, and all taxes, including
those due and owing and those accrued, and all other choses in action, and all
and every other interest of or belonging to or due to the Company and CSI shall
be taken and deemed to be transferred to, and vested in, the Surviving
Corporation without further act or deed; and all property, rights and
privileges, powers and franchises and all and every other interest shall be
thereafter as effectually the property of the Surviving Corporation as they were
of the Company and CSI; and the title to any real estate, or interest therein,
whether by deed or otherwise, vested in the Company and CSI, shall not revert or
be in any way impaired by reason of the Merger. Except as otherwise provided
herein, the Surviving Corporation shall thenceforth be responsible and liable
for all the liabilities and obligations of the Company and CSI and any claim
existing, or action or proceeding pending, by or against the Company or CSI may
be prosecuted as if the Merger had not taken place, or the Surviving Corporation
may be substituted in their place. Neither the rights of creditors nor any liens
upon the property of the Company or CSI shall be impaired by the Merger, and all
debts, liabilities and duties of the Company and CSI shall attach to the
Surviving Corporation, and may be enforced against such Surviving Corporation to
the same extent as if said debts, liabilities and duties had been incurred or
contracted by such Surviving Corporation.

                                    -2-

2.  CONVERSION OF STOCK; CLOSING

      Consideration (as defined below) specified opposite such holder's name on
      SCHEDULE 2.2;

            (b) all shares of Company Stock, if any, that are held by the

            (c) all shares of capital stock of CSI issued and outstanding
      immediately prior to the Effective Time shall continue and remain
      unaffected by the Merger and, together with the CSI Stock (as defined

forth below in this Section 3. For purposes of this Section 3, (i) the term
"Company" shall mean and refer to the Company and all of its subsidiaries, if
any. To the extent that any exception to any representation or warranty is
disclosed on any Schedule required by this Section 3, then such exception shall

(the "State of Incorporation"), and, except as set forth on SCHEDULE 3.1, has
all requisite power and authority to carry on its business as it is now being
conducted. The Company is duly qualified to do business and is in good standing
in each jurisdiction in which the nature of its business or the ownership or
leasing of its properties makes such qualification necessary, except where the
failure to be so authorized or qualified would not have a Material Adverse
Effect on the Company. SCHEDULE 3.1 sets forth a list of all jurisdictions in
which the Company is authorized or qualified to do business. True, complete and

arrangement on behalf of any employee or employees

                                    -9-

(such as, for example, and without limitation, any individual retirement account
or annuity, any "excess benefit plan" (within the meaning of Section 3(36) of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA")) or
any non-qualified deferred compensation arrangement). For the purposes of this
Agreement, the term "employee pension benefit plan" shall have the same meaning
as is given that term in Section 3(2) of ERISA. Neither the Company nor any of
its subsidiaries has sponsored, maintained or contributed to any employee
pension benefit plan other than the plans set forth on SCHEDULE 3.15, and
neither the Company nor any of its subsidiaries is required to contribute to any
retirement plan pursuant to the provisions of any collective bargaining
agreement establishing the terms and conditions or employment of any employees
of the Company or any of its subsidiaries.

      Except as set forth on SCHEDULE 3.15, the Company does not contribute to,
participate in, or otherwise have liability with respect to, any pension benefit
plan covered under the provisions of Title IV of ERISA. All employee benefit
plans listed on SCHEDULE 3.15 and the administration thereof are in substantial
compliance with their terms and all applicable provisions of ERISA and the
regulations issued thereunder, as well as with all other applicable federal,
state and local statutes, ordinances and regulations, and nothing has occurred
that could subject the Company to liability under Section 409 or Section 502 of
ERISA or Chapter 43 of Subtitle D or Section 6652 of the Code, or that has
subjected or could subject any participant in or beneficiary of a plan to a tax
under Section 4973 of the Code. There are no existing or, to the knowledge of
the Company and the Stockholders, threatened lawsuits, claims or other
controversies relating to any plan, other than claims for information or
benefits in the normal course. All accrued contribution obligations, premium
payments and assessments of the Company or any of its subsidiaries with respect
to any plan listed on SCHEDULE 3.15 have either been fulfilled in their entirety
or are fully reflected on the balance sheet of the Company as of the Balance
Sheet Date. All plans listed on SCHEDULE 3.15 that are intended to qualify (the
"Qualified Plans") under Section 401(a) of the Code are, and have been so
qualified and have been determined by the Internal Revenue Service to be so
qualified, and copies of the determination letters relating thereto are included
as part of SCHEDULE 3.15. Except as disclosed on SCHEDULE 3.15, all reports and
other documents required to be filed with any governmental agency or distributed
to plan participants or beneficiaries (including, but not limited to, actuarial
reports, audits or tax returns) have been timely filed or distributed, and
copies thereof are included as part of SCHEDULE 3.15. Neither the Stockholders,
any plan listed in SCHEDULE 3.15 nor the Company (including the Company's
subsidiaries) has engaged in any transaction prohibited under the provisions of
Section 4975 of the Code or Section 406 of ERISA. No plan listed in SCHEDULE
3.15 has incurred an "accumulated funding deficiency" (as defined in Section
412(a) of the Code and Section 302(1) of ERISA); and the Company (including the
Company's subsidiaries) has not incurred any liability for excise tax or penalty
due to the Internal Revenue Service or any liability to the Pension Benefit
Guaranty Corporation. There have been no terminations, partial terminations or
discontinuance of contributions to any such Qualified Plan intended to qualify
under Section 401(a) of the Code without notice to and approval by the Internal
Revenue Service; no plan listed in SCHEDULE 3.15 subject to the provisions of
Title IV of ERISA has been terminated; there have been no "reportable events"
(as defined in Section 4043 of ERISA) with respect to any such plan listed in
SCHEDULE 3.15; and the Company (including the Company's subsidiaries) has

                                    -10-

not incurred liability under Section 4062 of ERISA. In the case of each
Qualified Plan (other than a multiemployer plan) subject to Title IV of ERISA,
the current fair market value of the assets of such plan equals or exceeds the
present value of all benefit liabilities determined on a plan termination basis,
and in the case of each Qualified Plan subject to Title IV of ERISA that is a
multiemployer plan, the fair market value of assets equals or exceeds the
present value of all vested benefits and, as of the date hereof, there are no
unfunded vested benefits for which the Company is liable or would be liable in
the event that the transactions contemplated by this Agreement would result in a
withdrawal from such plan.

      3.26.  REORGANIZATION FOR FEDERAL INCOME TAX PURPOSES.

            (i) The fair market value of the CSI stock and other consideration
      received by each Stockholder in the Merger will be approximately equal to
      the fair market value of the Company Stock surrendered in the Merger.

            (ii) There is no plan or intention on the part of any of the
      Stockholders to sell, exchange or otherwise dispose of (by short sale or
      otherwise) a number of shares of CSI Stock received in the Merger that
      would reduce the Stockholders' ownership of CSI Stock to a number of
      shares having a value, as of the Closing Date, of less than 50% of the
      value of all of the formerly outstanding Company Stock as of immediately
      prior to the Merger. For purposes of this representation, shares of
      Company Stock exchanged for cash or other property, or exchanged for cash
      in lieu of fractional shares of CSI Stock, will be treated as outstanding
      Company Stock on the date of the Merger. Moreover, shares of the Company
      Stock and shares of CSI Stock held by the Stockholders and otherwise sold,
      redeemed or disposed of prior or subsequent to the Merger will be
      considered in making this representation.

            (iii) The liabilities of the Company assumed by CSI and the
      liabilities to which the transferred assets of the Company are subject
      were incurred by the Company in the ordinary course of its business.

            (iv) The Company and the Stockholders will pay their respective
      expenses, if any, incurred in connection with the Merger.

            (v) There is no intercorporate indebtedness existing between CSI and
      the Company that was issued, acquired or will be settled at a discount.

            (vi) The Company is not an investment company as defined in Section
      368(a)(2)(F)(iii) and (iv) of the Code.

            (vii) The Company is not under the jurisdiction of a court in a
      Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the
      Code.

            (viii) The fair market value of the assets of the Company
      transferred to CSI will equal or exceed the sum of its liabilities assumed
      by CSI, plus the amount of liabilities, if any, to which the transferred
      assets are subject.

      3.27. NO OTHER REPRESENTATIONS OR WARRANTIES. Except for representations
and warranties contained in this Agreement and in certificates delivered by the
Stockholders in connection with the Closing, the Stockholders:

            (i) make no representation or warranty, express or implied, written
      or oral, and

                                    -15-

            (ii) disclaim any such representation or warranty (including,
      without limitation, any warranty of merchantability or of fitness for a
      particular purpose), whether by the Stockholders, the Company, any of
      their respective officers, directors, employees, agents or representatives
      or any other person,

in each case with respect to the Company or the execution and delivery of this
Agreement or the transactions contemplated hereby, notwithstanding the delivery
or disclosure by the Stockholders or the Company or any of their respective
affiliates, officers, directors, employees, agents or representatives or any
other person to CSI, any affiliate of CSI or any of their respective officers,
directors, employees, agents or representatives or any other person of any
documentation or other information with respect to any one or more of the
foregoing.

4.  REPRESENTATIONS OF CSI

      CSI represents and warrants to each of the Stockholders as set forth below
in this Section 4. Any reference in this Section 4 or elsewhere in this
Agreement to a "Material Adverse Effect" on CSI shall mean a material adverse
effect on the business, operations, assets or financial condition of CSI and its
subsidiaries, taken as a whole.

      4.1. DUE ORGANIZATION. CSI is a corporation duly incorporated, validly
existing and in good standing under the laws of the State of Delaware, and has
the requisite power and authority to carry on its business as it is now being
conducted. CSI is qualified to do business and is in good standing in each
jurisdiction in which the nature of its business makes such qualification
necessary, except where the failure to be so authorized or qualified would not
have a Material Adverse Effect.

      4.2. AUTHORIZATION. (i) The representatives of CSI executing this
Agreement have the authority to enter into and bind CSI to the terms of this
Agreement and (ii) CSI has the full legal right, power and authority to enter
into this Agreement and the Merger.

      4.3. NO VIOLATIONS. The execution of this Agreement and the performance of
the obligations hereunder and the consummation of the transactions contemplated
hereby will not result in any violation or breach or constitute a default under
any of the terms or provisions of the Company's Restated Certificate of
Incorporation or Amended and Restated By-laws, each as amended.

      4.4. VALIDITY OF OBLIGATIONS. The execution and delivery of this Agreement
by CSI and the performance of the transactions contemplated herein have been
duly and validly authorized by the Board of Directors of CSI and this Agreement
has been duly and validly authorized by all necessary corporate action and is a
legal, valid and binding obligation of CSI.

                                    -16-

      4.5. CSI STOCK. At the time of issuance thereof, the CSI Stock to be
delivered to the Stockholders pursuant to this Agreement will constitute valid
and legally issued, fully paid and nonassessable shares of CSI.

      4.6. INVESTIGATION BY CSI. CSI has conducted its own investigation and
examination of the Company and its assets, liabilities (actual, accrued and
contingent), condition (financial and otherwise), businesses, operations,
affairs and prospects based primarily upon its own knowledge and experience and
upon information and data provided by the Stockholders and management of the
Company. CSI has the knowledge and experience necessary, and has consulted with
such legal, financial and other professional advisers as CSI has deemed
necessary, to review such information and data and, based upon such information
and data, such knowledge and experience and such professional advice, to
evaluate the merits and risks associated with the Merger and the other
transactions contemplated hereby. Notwithstanding (i) the investigation and
examination made by CSI, (ii) the knowledge and experience of CSI and (iii) the
professional advice received by CSI, in each case with respect to the Company,
the Merger and the other transactions contemplated by this Agreement, CSI is
expressly relying on the truth and accuracy of the representations and
warranties of the Company and the Stockholders contained in this Agreement and
in all certificates delivered by the Company and the Stockholders in connection
with the Closing.

      4.7. SEC REPORTS. Since July 2, 1997, CSI has filed all required forms,
reports and documents with the Securities and Exchange Commission (the "SEC"),
and, at the time of its filing with the SEC, each such form, report and document
complied in all material respects with all applicable requirements of the
Securities Act of 1933, as amended (the "Securities Act"), and the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), each as then in effect.
Since July 2, 1997, at the time of its filing or effectiveness, no report or
registration statement filed by CSI with the SEC contained any untrue statement
of a material fact or omitted to state a material fact necessary to make the
statements contained therein, in light of the circumstances under which they
were made, not misleading.

      4.8. ABSENCE OF CHANGES. Except as set forth in the reports and documents
filed by CSI with the SEC, from August 11, 1997 to the date hereof, there has
not been any change or any development or combination of developments which
would be required to be disclosed as a material change in response to Item 11 of
a registration statement on Form S-3 under the Securities Act or which has had
or would reasonably be expected to have a Material Adverse Effect on CSI.

      4.9.  REORGANIZATION FOR FEDERAL INCOME TAX PURPOSES.

            (i) CSI has no current plan or intention to reacquire any of the CSI
      Stock issued in the Merger.

            (ii) CSI has no current plan or intention (a) to sell or otherwise
      dispose of any of the assets of the Company acquired in the Merger, except
      for dispositions made in the

                                    -17-

      ordinary course of business or transfers of assets described in Section
      368(a)(2)(C) of the Code.

            (iii) CSI will continue, or will cause F&G Mechanical Corporation, a
      Delaware corporation and wholly owned subsidiary of CSI ("Newco"), to
      continue, the historic business of the Company, or CSI will use, or will
      cause Newco to use a significant portion of the Company's historic
      business assets in a business.

            (iv) CSI will pay its expenses, if any, incurred in connection with
      the Merger.

            (v) There is no intercorporate indebtedness existing between CSI and
      the Company that was issued, acquired or will be settled at a discount.

            (vi) CSI is not an investment company as defined in Sections
      368(a)(2)(F)(iii) and (iv) of the Code.

            (vii) None of the compensation paid by CSI to any
      Stockholder-employee will be separate consideration for, or allocable to,
      any of their Company Stock; none of the shares of CSI Stock issued to any
      Stockholder-employee will be separate consideration for, or allocable to,
      any employment agreement; and the compensation paid to any
      Stockholder-employee will be for services actually rendered and will be
      commensurate with amounts paid to third parties bargaining at arm's-length
      for similar services.

      4.10. NO OTHER REPRESENTATIONS OR WARRANTIES. Except for representations
and warranties contained in this Agreement and in certificates delivered by CSI
in connection with the Closing, CSI:

            (i) make no representation or warranty, express or implied, written
      or oral, and

            (ii) disclaim any such representation or warranty (including,
      without limitation, any warranty of merchantability or of fitness for a
      particular purpose), whether by CSI, any of its officers, directors,
      employees, agents or representatives or any other person,

in each case with respect to CSI or the execution and delivery of this Agreement
or the transactions contemplated hereby, notwithstanding the delivery or
disclosure by CSI or any of its affiliates, officers, directors, employees,
agents or representatives or any other person to any Stockholder, the Company,
any affiliate of the Company or any of their respective officers, directors,
employees, agents or representatives or any other person of any documentation or
other information with respect to any one or more of the foregoing.

                                    -18-

5.  COVENANTS PRIOR TO CLOSING

      8.2.  PREPARATION AND FILING OF TAX RETURNS.

            (i) The Stockholders shall file or cause to be filed all Tax returns
      for the Company for all taxable periods that end on or before the Closing
      Date, but in each case only after CSI has reviewed such returns and
      consented thereto (which consent shall not be unreasonably withheld). The
      Stockholders shall pay or cause to be paid all Tax liabilities (in excess
      of all amounts already paid with respect thereto) shown by such Tax
      returns to be due.

            (ii) Each party hereto shall, and shall cause its subsidiaries and
      affiliates, if any, to, provide to each of the other parties hereto such
      cooperation and information as any of them reasonably may request in
      filing any Tax returns, amended Tax returns or claims for refund,
      determining a liability for Taxes or a right to refund of Taxes or in
      conducting any audit or other proceeding in respect of Taxes. Such
      cooperation and information shall include providing copies of all relevant
      portions of relevant Tax returns, together with relevant accompanying
      schedules and relevant work papers, relevant documents relating to rulings
      or other determinations by taxing authorities and relevant records

      each party required to file Tax returns pursuant to this Agreement shall
      bear all costs of filing such Tax returns.

      8.3. GRANT OF STOCK OPTIONS. At the first meeting of the Compensation
Committee of the Board of Directors of CSI after the Closing Date, CSI will
recommend that the Compensation Committee grant to Newco stock options to

income tax liability of the Stockholders in respect of the taxable income of the
Company during the period from January 1, 1998 to the Closing Date.

      8.5. TERMINATION OF PROFIT SHARING PLAN. As soon as reasonably practicable
after the Closing, the Stockholders shall in good faith take all steps that are
necessary to effectuate the termination of the F&G Mechanical Corp. Profit
Sharing Plan and Trust and to obtain the requisite approvals of the Internal
Revenue Service to such termination.

9.  INDEMNIFICATION

      The Stockholders and CSI each make the following covenants that are
applicable to them, respectively:

      9.1. SURVIVAL OF STOCKHOLDER'S REPRESENTATIONS AND WARRANTIES. Except as
otherwise set forth on SCHEDULE 9.1, the representations and warranties made in
this Agreement and in the documents and certificates delivered in connection
herewith shall survive the Merger for a period of two years from the Closing
Date; PROVIDED, HOWEVER, that all representations and warranties with respect to
which a claim is made within the applicable survival period shall survive until
such claim is finally determined and paid. The date on which a representation or
warranty expires as provided herein is referred to herein as the "Expiration
Date." No claim for indemnification may be made with respect to a representation
or warranty after the Expiration Date, other than claims based on intentional
fraud.

      9.2. GENERAL INDEMNIFICATION BY THE STOCKHOLDERS. Except as otherwise set
forth on SCHEDULE 9.1, the Stockholders covenant and agree that they will
jointly and severally indemnify, defend, protect, and hold harmless CSI, Newco,
the Surviving Corporation and their respective subsidiaries and officers,
directors, employees, stockholders, agents, representatives and affiliates at
all times from and after the date of this Agreement until the Expiration Date
from and against all claims, damages actions, suits, proceedings, demands,
assessments, adjustments, costs and expenses (including specifically, but
without limitation, reasonable attorneys' fees and expenses of investigation)
(collectively "Damages") incurred by such indemnified person, except and to the
extent such Damages (i) are recoverable by CSI, Newco and the Surviving
Corporation under any applicable insurance policies or (ii) are reserved against
in the Financial Statements, arising from or relating to (a) any breach of any
representation or warranty made by any Stockholder in this Agreement; (b) any
breach of any covenant made by any Stockholder or the Company in this Agreement;
(c) any violation of any Environmental Law prior to the Closing; (d) any release
of Hazardous Wastes, Hazardous Materials or Hazardous Substances affecting any
real property formerly owned or operated by the Company or any predecessor of
the Company, but no longer owned or operated by the Company at the Closing; and
(e) any liability for Taxes of the Company for any period (or portion thereof)
ending on or prior to the Closing Date.

      9.3. INDEMNIFICATION BY CSI. CSI covenants and agrees that it will
indemnify, defend, protect and hold harmless the Stockholders at all times from
and after the date of this Agreement

                                    -28-

until the Expiration Date from and against all Damages incurred by the
Stockholders as a result of (i) any breach of any representation or warranty of
CSI set forth herein or in the certificates delivered in connection herewith;
and (ii) any breach or nonfulfillment of any covenant or agreement by CSI under
this Agreement.

      9.4.  INDEMNIFICATION PROCEDURE.

            (i) Any party seeking indemnification hereunder (the "Indemnitee")
      shall notify the party liable for such indemnification (the "Indemnitor")
      in writing of any event, omission or occurrence which the Indemnitee has
      determined has given or could give rise to Damages which are indemnifiable
      hereunder (such written notice being hereinafter referred to as a "Notice
      of Claim"). Any Notice of Claim shall be given promptly after the
      Indemnitee becomes aware of such event, omission or occurrence. The
      failure of any Indemnitee to give notice as provided in this Section 9.4
      shall not relieve the Indemnitor of its obligations hereunder, except to
      the extent that the Indemnitor is actually prejudiced by such failure to
      give notice. A Notice of Claim shall specify in reasonable detail the
      nature and any particulars of the event, omission or occurrence giving
      rise to a right of indemnification.

            (ii) This indemnity is conditioned upon and subject to the
      Indemnitee giving its full cooperation in complying with any applicable
      foreign, federal, state or local laws, rules or regulations or any
      discovery or testimony necessary to effectively carry out the Indemnitor's
      obligations hereunder. Such cooperation shall be without charge to the
      Indemnitor.

      9.5. CLAIM BY THIRD PARTIES. If a party to this Agreement seeks
indemnification hereunder with respect to a claim by a third party, then this
Section 9.5 shall apply.

            (i) For the purposes of this Section 9.5, "Third Party Claim" means
      any demand which has been made on, or communicated to, CSI, Newco, the
      Surviving Corporation or any Stockholder by or on behalf of any person
      other than CSI, Newco, the Surviving Corporation or any Stockholder and
      which, if maintained or enforced, might result in a claim for
      indemnification in the nature described in Section 9.2 or 9.3 being made.

            (ii) Promptly upon receipt by the Indemnitee of notice of any Third
      Party Claim in respect of which the Indemnitee proposes to demand
      indemnification from the Indemnitor, the Indemnitee shall forthwith give
      notice to that effect to the Indemnitor.

            (iii) If the Indemnitor acknowledges in writing the Indemnitor's
      duty to indemnify with respect to such Third Party Claim, the Indemnitor
      shall have the right, exercisable by giving notice to the Indemnitee
      promptly after receipt of any notice of any Third Party Claim under
      Section 9.5(ii), to assume the defense of such Third Party Claim. If the
      Indemnitee reasonably believes that the Indemnitor may not be able to pay
      any Damages

                                    -29-

      resulting from any Third Party Claim, as a condition of the Indemnitor
      assuming defense of such claim, the Indemnitee shall be entitled to
      reasonable security from the Indemnitor for the Damages to which the
      Indemnitee may be exposed.

            (iv) Upon the assumption of the defense by the Indemnitor as
      aforesaid, the Indemnitor shall, at its expense, diligently proceed with
      the defense of such Third Party Claim at the Indemnitor's sole expense,
      including employment of counsel reasonably satisfactory to the Indemnitee.
      In connection therewith, so long as the Indemnitor is defending in good
      faith such Third Party Claim, the Indemnitee shall cooperate fully, but at
      the expense of the Indemnitor, to make available to the Indemnitor all
      pertinent information and witnesses under the Indemnitee's control and to
      make such assignments and take such other steps as, in the opinion of
      counsel for the Indemnitor, are necessary to enable the Indemnitor to
      conduct such defense. The Indemnitee shall have the right, but not the
      obligation, to participate, at its own expense, in the defense of such
      Third Party Claim through counsel of its own choice, and shall have the
      right, but not the obligation, to assert any and all allowable crossclaims
      or counterclaims it may have pursuant to this Section 9.

            (v) With respect to the defense of any Third Party Claim undertaken
      by the Indemnitor, any compromise or settlement of such Third Party Claim
      by the Indemnitor which would result in a payment obligation of, or
      injunctive relief against, or a criminal admission by, the Indemnitee,
      shall not be made or effective against the Indemnitee without the prior
      written consent of the Indemnitee.

            (vi) If the Indemnitor fails to give notice of a Third Party Claim
      to the Indemnitee as provided in Section 9.5(ii), or if the Indemnitor
      fails to defend, contest or otherwise protect against any Third Party
      Claim, the Indemnitee shall have the right, but not the obligation, to
      defend, contest or to otherwise protect against such Third Party Claim;
      PROVIDED, HOWEVER, that the Indemnitee shall keep the Indemnitor
      reasonably advised as to the current status and progress of such Third
      Party Claim. The Indemnitee shall have the right, but not the obligation,
      to make any compromise or settlement of any such Third Party Claim, and,
      to the extent it is determined that the Indemnitor is liable for the
      Damages in connection therewith, the Indemnitee shall be entitled to
      indemnification of all amounts paid as a result of such Third Party Claim
      or any compromise or settlement thereof; PROVIDED, HOWEVER, that any such
      compromise or settlement which would result in a payment obligation of, or
      injunctive relief against, or a criminal admission by, the Indemnitor or
      the Indemnitee shall not be made or effective against the Indemnitor or
      the Indemnitee without the prior written consent of each of the Indemnitor
      and the Indemnitee, which consent shall not be unreasonably withheld.

            (vii) If the Indemnitor assumes and diligently defends any Third
      Party Claim, then the Indemnitor shall be relieved of the obligation to
      reimburse the Indemnitee for any other legal, accounting or other
      out-of-pocket costs and expenses incurred by the Indemnitee

                                    -30-

      with respect to the defense of such Third Party Claim after receipt by the
      Indemnitee of the notice referred to in Section 9.5(ii), notwithstanding
      any participation by the Indemnitee in the defense of such Third Party
      Claim.

            (viii) If the Indemnitee subsequently recovers all or any part of
      the Third Party Claim from any other person legally obligated to pay all
      or any part of such claim, the Indemnitee shall forthwith repay to the
      Indemnitor the amounts recovered up to an amount not exceeding the
      aggregate payments made by the Indemnitor to the Indemnitee by way of
      indemnification in respect of such Third Party Claim under this Section 9
      or otherwise.

            (ix) The obligations of CSI and the Stockholders under this Section
      9.5 are subject to the limitations set forth in Sections 9.1 and 9.7 and
      on SCHEDULE 9.1.

      9.6. METHOD OF PAYMENT. All claims for indemnification shall be paid in
cash; PROVIDED, HOWEVER, that if the Stockholders are required to pay any claim
for indemnification, then the Stockholders may, at their election, pay such
claim for indemnification in CSI Stock at its fair market value at the time of
payment.

      9.7. LIMITATIONS ON INDEMNIFICATION. Except as otherwise set forth on
SCHEDULE 9,1, CSI, Newco, the Surviving Corporation and the other persons or
entities indemnified pursuant to this Section 9 shall not assert any claim for
indemnification hereunder against the Stockholders until such time as, the
aggregate of all claims which such persons may have against the Stockholders
shall exceed $455,000 (the "Indemnification Threshold"). The Stockholders shall
not assert any claim for indemnification hereunder against CSI or Newco until
such time as the aggregate of all claims which the Stockholders may have against
CSI or Newco shall exceed the Indemnification Threshold.

      No person shall be entitled to indemnification under this Section 9 if and
to the extent that such person's claim for indemnification is directly or
indirectly caused by a breach by such person of any representation, warranty,
covenant or other agreement set forth in this Agreement.

      Except as otherwise set forth on SCHEDULE 9.1, the aggregate liability of
the Stockholders for indemnification claims under this Section 9 shall be
limited to $45,500,000. The aggregate liability of CSI for indemnification
claims under this Section 9 shall be limited to $45,500,000.

10.  TERMINATION OF AGREEMENT

      10.1. TERMINATION. This Agreement may be terminated at any time prior to
the Closing Date solely:

            (i) by mutual consent of the respective Boards of Directors of CSI
      and the Company;

                                    -31-

            (ii) by the Company (acting through its Board of Directors), or by
      CSI (acting through its Board of Directors), if the transactions
      contemplated by this Agreement to take place at the Closing shall not have
      been consummated by February 15, 1998 (the "Termination Date"), unless the
      failure of such transactions to be consummated is due to the willful
      failure of any party seeking to terminate this Agreement to perform any of
      its obligations under this Agreement to the extent required to be
      performed by it prior to or on the Closing Date; or

            (iii) by the Stockholders or the Company, on the one hand, or by
      CSI, on the other hand, if a material breach or default shall be made by
      another party in the observance or in the due and timely performance of
      any of the covenants or agreements contained herein, and the curing of
      such default shall not have been made on or before the Termination Date.

      10.2. LIABILITIES IN EVENT OF TERMINATION. The termination of this
Agreement will in no way limit any obligation or liability of any party based on
or arising from a breach or default by such party with respect to any of its
representations, warranties, covenants or agreements contained in this Agreement
including, but not limited to, legal and audit costs and out-of-pocket expenses.

11.  NONCOMPETITION

      11.1. PROHIBITED ACTIVITIES. The Stockholders will not, for a period of
five years following the Closing Date, for any reason whatsoever, directly or
indirectly, for themselves or on behalf of or in conjunction with any other
person, persons, company, partnership, corporation or business of whatever
nature:

            (i) engage, as an officer, director, shareholder, owner, partner,
      joint venturer, or in a managerial capacity, whether as an employee,
      independent contractor, consultant or advisor, or as a sales
      representative, in any business offering mechanical contracting, heating,
      ventilation, air conditioning, fire suppression or related services or
      products (the "Business") in competition with CSI or any of its
      subsidiaries within 100 miles of where any Company or any of its
      subsidiaries conducts or has conducted business (the "Territory");

            (ii) solicit any employee of CSI or any of its subsidiaries for the
      purpose or with the intent of enticing such employee away from or out of
      the employ of CSI or any of its subsidiaries;

            (iii) call upon any person or entity which is or has been within two
      years prior to the Closing Date, a customer of any Company or any of its
      subsidiaries for the purpose of soliciting or selling products or services
      of the Business in direct competition with CSI or any of its subsidiaries.

                                    -32-

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any Stockholder from acquiring as a passive investor with no
involvement in the operations or management of the business, not more than 2% of
the capital stock of a competing business whose stock is publicly traded on a
national securities exchange or over-the-counter market.

      11.2. EQUITABLE RELIEF. Because of the difficulty of measuring economic
losses to CSI as a result of a breach of the foregoing covenant, and because of
the immediate and irreparable damage that could be caused to CSI for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by CSI in the event of breach by such Stockholder, by
injunctions, restraining orders and other equitable actions.

      11.3. REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 11 impose a reasonable restraint on the
Stockholders in light of the activities and business of CSI and its subsidiaries
on the date of the execution of this Agreement and the current plans of CSI; but
it is also the intent of CSI and the Stockholders that such covenants be
reasonably construed and enforced in accordance with the changing activities,
business and locations of CSI and its subsidiaries throughout the term of this
covenant. During the term of this covenant, if CSI or one of its subsidiaries
engages in related or similar activities, enters a related or similar business
or establishes new locations for its current activities or business, in each
case within the Territory, then the Stockholders will be prohibited from
competing with such activities or business within the Territory.

      11.4. SEVERABILITY; REFORMATION. The covenants in this Section 11 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      11.5. INDEPENDENT COVENANT. The Stockholders acknowledge that their
covenants set forth in this Section 11 are material conditions to CSI's
willingness to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. All of the covenants in this Section 11 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any Stockholder
against CSI or any subsidiary thereof, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by CSI of such
covenants. It is specifically agreed that the period of five years stated at the
beginning of this Section 11, during which the agreements and covenants of each
Stockholder made in this Section 11 shall be effective, shall be computed by
excluding from such computation any time during which such Stockholder is
determined by a court of competent jurisdiction or by agreement of the parties
to have been in material violation of any provision of this Section 11. The
covenants contained in Section 11 shall not be affected by any breach of any
other provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

                                    -33-

12.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      12.1. GENERAL. The Stockholders recognize and acknowledge that they had in
the past, currently have, and in the future may possibly have, access to certain
confidential information of the Company and/or CSI, such as operational
policies, pricing and cost policies, and other information, that are valuable,
special and unique assets of the Company and/or CSI. The Stockholders agree that
they will not disclose such confidential information to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except (i) to authorized representatives of CSI, (ii) following the Closing,
such information may be disclosed by the Stockholders as is required in the
course of performing their duties for CSI or Newco and (iii) to counsel and
other advisers, provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 12.1, unless (a) such information
becomes known to the public generally through no fault of the Stockholders, or
(b) disclosure is required by law or the order of any governmental authority
under color of law, provided, that prior to disclosing any information pursuant
to this clause (b), the Stockholders shall, if possible, give prior written
notice thereof to CSI and provide CSI with the opportunity to contest such
disclosure. In the event of a breach or threatened breach by any Stockholder of
the provisions of this Section 12.1, CSI shall be entitled to injunctive or
other equitable relief restraining such Stockholder from disclosing, in whole or
in part, such confidential information. Nothing herein shall be construed as
prohibiting CSI from pursuing any other available remedy for such breach or
threatened breach, including the recovery of damages.

      12.2. EQUITABLE RELIEF. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which CSI would have
no other adequate remedy, the Stockholders agree that the foregoing covenants
may be enforced against them by injunctions, restraining orders and other
appropriate equitable relief.

      12.3. SURVIVAL. The obligations of the parties under this Section 12 shall
survive the termination of this Agreement for a period of five years.

13.  INTENDED TAX TREATMENT

      TAX-FREE REORGANIZATION. CSI , the Company and the Stockholders are
entering into this Agreement with the intention that the merger of the Company
into CSI qualify as a reorganization described in Section 368(a)(1)(A) of the
Code for federal income tax purposes, and CSI, the Company and the Stockholders
will not take any actions that disqualify such merger for such treatment. The
parties hereto shall treat such merger as a tax-free reorganization with respect
to all federal, state and local income tax reporting requirements, except to the
extent of any "boot" received. Neither the Company nor any Stockholder will take
any position on its or his tax returns or in any other filings required to be
made with a governmental agency that is

                                    -34-

inconsistent with the treatment of the transaction contemplated by this
Agreement as a reorganization described in Section 368(a)(1)(A) of the Code.
Further, each of the Company and the Stockholders shall comply with the record
keeping and filing requirements of Treasury Regulation Section 1.368-3.

14.  SECURITIES LAW MATTERS

      14.1. ECONOMIC RISK; SOPHISTICATION. Each Stockholder represents and
warrants that such Stockholder has not relied on any purchaser representative,
or on the Company or any other Stockholder, in connection with the acquisition
of shares of CSI Stock hereunder. The Stockholders each (i) have such knowledge,
sophistication and experience in business and financial matters that they are
capable of evaluating the merits and risks of an investment in the shares of CSI
Stock, (ii) fully understand the nature, scope and duration of any limitations
on transfer described in this Agreement and (iii) can bear the economic risk of
an investment in the shares of CSI Stock and can afford a complete loss of such
investment. The Stockholders have each had an adequate opportunity to ask
questions and receive answers from the officers of CSI concerning any and all
matters relating to the transactions described herein including without
limitation the background and experience of the officers and directors of CSI,
the plans for the operations of the business of CSI, the business, operations
and financial condition of CSI, and any plans for additional acquisitions and
the like. The Stockholders have each asked any and all questions in the nature
described in the preceding sentence and all questions have been answered to
their satisfaction.

      14.2. COMPLIANCE WITH LAW. Each Stockholder covenants that none of the CSI
Stock will be offered, sold, assigned, hypothecated, transferred or otherwise
disposed of by such Stockholder except after full compliance with all of the
applicable provisions of the Securities Act and the rules and regulations of the
Securities and Exchange Commission.

      14.3. RESALE LIMITATIONS. The CSI Stock to be issued will not be
registered pursuant to the Securities Act and each Stockholder may not transfer
the CSI Stock except pursuant to registration under the Securities Act, or
pursuant to a valid exemption from registration under the Securities Act
(including the limitations on resale under Rule 144 promulgated under the
Securities Act). Additionally, the certificates evidencing the CSI Stock will
bear a legend substantially in the form set forth below:

      THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
      THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE SOLD OR
      OTHERWISE TRANSFERRED, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT
      TO SUCH SALE OR TRANSFER, UNLESS THE HOLDER HEREOF COMPLIES WITH THE ACT
      AND APPLICABLE SECURITIES LAW.

                                    -35-

      dispose of, or reduce his risk with respect to, one-third of the shares of
      CSI Stock to be issued to such Stockholder and (b) the certificates
      representing such shares of CSI Stock shall bear the following legend:

            RESTRICTION ON TRANSFER AND MAY NOT BE SOLD, ASSIGNED, PLEDGED OR
            OTHERWISE ENCUMBERED, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE

            THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
            RESTRICTION ON TRANSFER AND MAY NOT BE SOLD, ASSIGNED, PLEDGED OR
            OTHERWISE ENCUMBERED, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE
            EFFECT TO ANY SUCH TRANSACTION, UNTIL FEBRUARY 12, 2002, WITHOUT THE
            WRITTEN CONSENT OF THE ISSUER.

            (iv) Notwithstanding the foregoing provisions of this Section 14.4,
      the contractual restrictions on transfer of CSI Stock contained in this
      Section 14.4 shall not apply to any gift of CSI Stock by any Stockholder
      to his family members or to any charitable organization; PROVIDED,
      HOWEVER, that (a) the aggregate amount of all such gifts by any
      Stockholder shall not exceed $1,500,000, (b) each transferee of such CSI
      Stock shall be

                                    -36-

      subject to, and shall agree with CSI in writing to comply with, the
      contractual restrictions set forth in this Section 14.4 and (c) the
      certificates representing the CSI Stock issued to each transferee shall
      bear the same legends as the certificates representing the CSI Stock
      submitted for transfer by the applicable Stockholder.

deliver or cause to be delivered to the other on the Closing Date, and at such
other times and places as shall be reasonably agreed to, such additional
