AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER (this "Agreement") made effective as of
August 18, 1997, by and among Group Maintenance America Corp., a Texas
corporation (the "Parent"), LSC Acquisition Corp., a California corporation
("Merger Sub"), Linford Service Company, a California corporation (the
"Company"), and the undersigned holders of all of the outstanding capital stock
of the Company (the "Shareholders").

WHEREAS, the respective Boards of Directors of the Parent, Merger Sub and
the Company have each approved the merger of the Company with and into Merger
Sub (the "Merger") pursuant to this Agreement and the applicable statutes of the
State of California, and pursuant to the Merger each issued and outstanding
share of Common Stock, no par value, of the Company ("Company Common Stock")
will be converted into the right to receive certain shares of common stock,
$.001 par value per share, of the Parent ("Parent Common Stock"), and certain
cash consideration, all as provided herein;

WHEREAS, the Merger has been approved, as required by applicable law, by
the Parent, acting as sole shareholder of Merger Sub, and by the Shareholders,
as the holders of all of the outstanding capital stock of the Company;

WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code").

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

1. THE MERGER

1.1 The Merger. Subject to the terms and conditions hereof, and in
accordance with Section 1103 of the California Corporations Code (the
"Applicable Corporate Law"), upon the Effective Time (as defined in Section

surviving entity following the Merger, is sometimes referred to in this
Agreement as the "Surviving Corporation."

1.2 Effective Time of the Merger. In accordance with the requirements of
applicable law, appropriate documents under the Applicable Corporate Law shall
be prepared, executed and submitted for filing with the California Corporations
Commission as soon as practicable following the Closing (as defined below). The
date of such filing is referred to in this Agreement as the "Effective Time."

1.3 Closing. The closing of the Merger ("Closing") will take place at
10:00 a.m. at the offices of the Parent in Houston, Texas on the date of the
closing of the Parent's IPO (as defined below), but in no event later than
December 31, 1997 ("Closing Date"); provided that each of the conditions
precedent to the obligations of the parties to effect the Merger set forth in
Article 5 of

this Agreement are then satisfied or waived by the applicable party. The parties
may agree in writing on another date, time or place for the Closing. At the
Closing, the parties will deliver or cause to be delivered the documents
described in Sections 5.3 and 5.4 below. The term "IPO" means any underwritten

employee benefit plan or interest therein, (iii) relating principally to any
preferred stock or debt securities of the Parent, or (iv) filed pursuant to Rule
145 under the Securities Act of 1933, as amended ("Securities Act"), or any
successor or similar provision). The term "Minimum Proceeds" means the aggregate
amount necessary to pay in full (i) all indebtedness of the Parent or any of its
subsidiaries outstanding at the closing of the IPO incurred for purposes of
financing any acquisitions by the Parent or any of its subsidiaries, (ii) the
aggregate redemption prices for the redemption of all of the Parent's preferred
stock outstanding at the closing of the IPO issued by the Parent in connection
with then completed acquisitions by the Parent or any of its subsidiaries, and
(iii) the aggregate cash payable by the Parent or any of its subsidiaries in
connection with all then pending acquisitions.

Amounts within 10 business days following receipt of the Statement of Final Per
Share Amounts, specifying in reasonable detail the nature and extent of such

Final Per Share Cash Amounts payable to such Shareholder, as finally determined
pursuant hereto, exceeds the aggregate of the Closing Per Share Cash Amounts
paid to such Shareholder at the Closing; and (b) the number of shares of Parent
Common Stock, if any, by which the aggregate of the Final Per Share Common Stock
Amounts deliverable to such Shareholder, as finally determined pursuant hereto,

deemed to have waived their respective rights and remedies hereunder for, and
the Shareholders shall have no liability with respect to, any such specifically
identified breach, to the extent so identified by the Company and so waived by
the Parent. Prior to the Closing, the Parent will promptly notify the Company
and the Shareholders if it believes that any representation of the Shareholders

warranty, covenant or agreement herein by the Parent or Merger Sub irrespective
of any knowledge of or investigation with respect thereto made by or on behalf
of any Shareholder; provided, however, that if the Parent shall disclose in

fines, assessments, charges and costs, including reasonable attorneys' fees and
court costs (net of any insurance recoveries)(collectively "Losses") arising
from, out of or in any manner connected with or based on:

(i) the breach of any covenant of the Shareholders or the Company or
the failure by the Shareholders or the Company to perform any obligation of
the Shareholder or the Company contained herein or in any Company Related
Document or Shareholder Related Document;

(ii) any inaccuracy in or breach of any representation or warranty of

and 6.3, the Parent shall indemnify, save and hold harmless the Shareholders and
the Shareholders' heirs, legal representatives, successors and assigns from and
against all Losses arising from, out of or in any manner connected with or based
on:

(i) any breach of any covenant of the Parent or Merger Sub or the
failure by the Parent or Merger Sub to perform any of its obligations
contained herein or in the Parent Related Documents;

(ii) any inaccuracy in or breach of any representation or warranty of

Documents; and

(iii) any act, omission, event, condition or circumstance occurring
or existing at any time after (but not on or before) the Effective Time and
involving or relating to the assets, properties, businesses or operations
of the Company; provided, however, that this clause (iii) shall not apply
to any Losses to the extent that such Losses result from any Shareholder's
acts or omissions after the Effective Time as an officer, director and/or
employee of the Parent, the Surviving Corporation and/or any other
affiliate of the Parent.

The foregoing indemnities shall not limit or otherwise adversely affect the
Parent Indemnified Parties' rights of indemnity for Losses under Section 6.2.1.

6.3 Limitations. The aggregate liability of the Shareholders under
Section 6.2.1 (ii) and (iii) shall not exceed the cash amount equal to the Final
Merger Consideration, with the Parent Common Stock being valued at the IPO Price
to the Public for such purpose. The aggregate liability of the Parent under
Section 6.2.2(ii) shall not exceed the cash amount of the Final Merger
Consideration, with the Parent Common Stock being valued at the IPO Price to the

Public for such purpose. Furthermore, neither the Shareholders, on the one
hand, nor the Parent, on the other hand, shall have an obligation to provide
indemnification until the Losses for which indemnification is sought exceeds
$25,000, at which time indemnification may be sought for all such Losses.

6.4 Procedures for Indemnification.

6.4.1 Notice. The party (the "Indemnified Party") that may be
entitled to indemnity hereunder shall give prompt notice to any party obligated
to give indemnity hereunder (the "Indemnifying Party") of the assertion of any
claim, or the commencement of any suit, action or proceeding in respect of which
indemnity may be sought hereunder. Any failure on the part of any Indemnified
Party to give the notice described in this Section 6.4.1 shall relieve the
Indemnifying Party of its obligations under this Article 6 only to the extent
that such Indemnifying Party has been prejudiced by the lack of timely and
adequate notice (except that the Indemnifying Party shall not be liable for any
expenses incurred by the Indemnified Party during the period in which the
Indemnified Party failed to give such notice). Thereafter, the Indemnified Party
shall deliver to the Indemnifying Party, promptly (and in any event within 10
days thereof) after the Indemnified Party's receipt thereof, copies of all
notices and documents (including court papers) received by the Indemnified Party
relating to such claim, action, suit or proceeding.

6.4.2 Legal Defense. The Parent shall have the obligation to
assume the defense or settlement of any third-party claim, suit, action or
proceeding in respect of which indemnity may be sought hereunder, provided that
(i) the Shareholders shall at all times have the right, at their option, to
participate fully therein, and (ii) if the Parent does not proceed diligently to
defend the third-party claim, suit, action or proceeding within 10 days after
receipt of notice of such third-party claim, suit, action or proceeding, the
Shareholder shall have the right, but not the obligation, to undertake the
defense of any such third-party claim, suit, action or proceeding.

6.4.3 Settlement. The Indemnifying Party shall not be required to
indemnify the Indemnified Party with respect to any amounts paid in settlement
of any third-party suit, action, proceeding or investigation entered into
without the written consent of the Indemnifying Party; provided, however, that
if the Indemnified Party is a Parent Indemnified Party, such third-party suit,
action, proceeding or investigation may be settled without the consent of the
Indemnifying Party on 10 days' prior written notice to the Indemnifying Party if
such third-party suit, action, proceeding or investigation is then unreasonably
interfering with the business or operations of the Company or the Surviving
Corporation and the settlement is commercially reasonable under the
circumstances; and provided further, that if the Indemnifying Party gives 10
days' prior written notice to the Indemnified Party of a settlement offer which
the Indemnifying Party desires to accept and to pay all Losses with respect
thereto ("Settlement Notice") and the Indemnified Party fails or refuses to
consent to such settlement within 10 days after delivery of the Settlement
Notice to the Indemnified Party, and such settlement otherwise complies with the
provisions of this Section 6.4, the Indemnifying Party shall not be liable for
Losses arising from such third-party suit, action, proceeding or investigation
in excess of the amount proposed in such settlement offer. Notwithstanding the
foregoing, no Indemnifying Party will consent to the

entry of any judgment or enter into any settlement without the consent of the
Indemnified Party, if such judgment or settlement imposes any obligation or
liability upon the Indemnified Party other than the execution, delivery or
approval thereof and customary releases of claims with respect to the subject
matter thereof.

6.4.4 Cooperation. The parties shall cooperate in defending any
such third-party suit, action, proceeding or investigation, and the defending
party shall have reasonable access to the books and records, and personnel in
the possession or control of the Indemnified Party that are pertinent to the
defense. The Indemnified Party may join the Indemnifying Party in any suit,
action, claim or proceeding brought by a third party, as to which any right of
indemnity created by this Agreement would or might apply, for the purpose of
enforcing any right of the indemnity granted to such Indemnified Party pursuant
to this Agreement.

6.5 Insurance. Except as otherwise provided herein, Parent shall use
commercially reasonable efforts and shall cause the Surviving Corporation to
use commercially reasonable efforts to (i) file (or cause to be filed) claims
under insurance policies for all damages that may be recoverable in respect of
any losses thereunder, (ii) pursue all claims for indemnification, contribution
or other recoveries (whether for breach of contract or otherwise) under
agreements with third parties, and (iii) pursue all rights for contribution or
other recoveries against third parties afforded under applicable law. Nothing in
this Agreement shall be construed to require either Parent or the Surviving
Corporation to obtain insurance coverage for their respective operations, but
Parent shall cause the Surviving Corporation to be provided with insurance
coverage that is comparable with the insurance coverage that is provided to its
other subsidiaries. Any insurance policy covering the operations of the
Surviving Corporation shall waive subrogation by and between the signatories
hereto and will name Xxxxxx X. Xxxxxxx and Xxxxxx X. Xxxxxxx as named insureds
thereunder. In the event Parent or the Surviving Corporation determines to
cancel or not renew any insurance policy listed on Schedule 8(vi) of the
Disclosure Schedule, Parent shall give the Shareholders written notice the
earlier of 20 days prior to the effective date of such cancellation or
expiration or five days after receipt of a written notice of cancellation. The
Shareholders shall be afforded the opportunity to renew any such policy at their
own cost. Parent shall cooperate, and shall cause the Surviving Corporation to
cooperate, with the Shareholders in respect of the renewal or extension of such
insurance or in securing a replacement policy therefor. No right of subrogation
shall accrue hereunder to any insurer or other party. There shall be no third
party beneficiaries of any provision of this Section 6 other than the
Shareholders under Section 6.2.2.

the Parent, Merger Sub, the Company and the Shareholders.

acquisition" or other form of anti-takeover statute or regulation shall become
applicable to the transactions contemplated hereby, the Parent and the Company
and their respective members of their Boards of Directors shall grant such

it shall not be necessary to produce or account for more than one such
counterpart.

8.19 No Rule of Construction. All of the parties hereto have been

engaged by the Shareholders; provided further, that all fees, costs and expenses
incurred or payable by the Company in connection with the negotiation and
closing of this Agreement and the transactions contemplated hereby shall be
included in current liabilities for purposes of determining Working Capital.
Notwithstanding the foregoing, if the

Merger is not consummated as a result of (i) the termination of this agreement
by the Shareholders other than as a result of a material misrepresentation or
breach of covenant by the Parent, (ii) the representations and warranties of the
Company or the Shareholders are untrue or incorrect in any material respect and
such fact results in a final price that is unacceptable to the Company or (iii)
the Company or the Shareholders fail to perform or offer to perform all of their
material agreements and covenants, then the Company shall pay the fees of the
Accountants that do not exceed $35,000 (or shall reimburse the Parent for such
fees within 15 days after being requested to do so) and the Parent shall pay the
fees of the Accountants that exceed $35,000. If the Merger is consummated or the
Merger is not consummated for a reason not described in the preceding sentence,
