contractually required to hold some portions of those shares for periods of up
to two years. In addition, pursuant to the provisions of Rule 145 under the
Securities Act, the volume limitations and certain other requirements of Rule

                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by reference to, and
should be read in conjunction with, the more detailed information and the
financial statements, including the related notes thereto, appearing elsewhere
in this Prospectus. Unless the context otherwise requires, (i) the "Company"
refers to Group Maintenance America Corp. ("GroupMAC") and its subsidiaries, as
well as to the business and operations of their predecessors and (ii) all
information in this Prospectus relating to the number of shares of Common Stock
and per share amounts reflects the 1-for-2.5 reverse stock split effected prior
to the date of the closing of the initial public offering of the Company's
Common Stock (the "IPO") hereinafter referred to. References to fiscal year
financial information of the Company refer to the fiscal year ended February 28
or 29 of the relevant year or the respective fiscal year ends of the individual

                                  THE COMPANY
 
  The Company was founded in 1996 to create the leading nationwide provider of
heating, ventilation and air conditioning ("HVAC"), plumbing and electrical
services to residential and commercial/industrial customers. Since inception,
the Company has acquired 55 platform companies which represent $782.2 million
in combined 1997 revenues. The Company believes it is one of the largest
diversified providers of HVAC, plumbing and electrical services in the United
States.
 
  The Company offers a comprehensive range of services to residential and
commercial/industrial customers in both the new installation and the
maintenance, repair and replacement segments of the HVAC, plumbing and
electrical service industries. The Company's services include installing and
maintaining, repairing and replacing central air conditioning systems,
furnaces, heat pumps and plumbing and electrical systems.
 
  The Company is a Texas corporation with its principal executive offices
located at 8 Greenway Plaza, Suite 1500, Houston, Texas 77046, its telephone
number is (713) 860-0100, and its address on the world-wide web is
www.groupmac.com.
 
                                  RISK FACTORS
 
  An investment in the shares of Common Stock involves significant risks that a
potential investor should consider carefully. See "Risk Factors" beginning on
page 4 for certain information that should be considered by prospective
investors of the Common Stock offered hereby.
 
                                       3
<PAGE>
 
                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, prospective
investors in the Common Stock offered hereby should consider carefully the
following factors before deciding to invest in the Common Stock.
 
DEVELOPMENT, IMPLEMENTATION, AND INTEGRATION OF OPERATING SYSTEMS AND POLICIES
 
  As a rapidly growing provider of HVAC, plumbing and electrical services, the
Company is faced with the development, implementation and integration of
Company-wide policies and systems related to its operations. The Company plans
to implement and integrate certain information and operating systems and
procedures for its subsidiaries including, but not limited to, accounting
systems, employment and human resources policies, uniform purchasing programs
and certain centralized marketing programs. Its subsidiaries may need to
modify certain systems and policies they have utilized historically to
implement the Company's systems and policies. As a result of the Company's
decentralized operating strategy, there can be no assurance that the Company's
operating systems and policies will be successfully implemented at the
subsidiary level or that the Company will be successful in monitoring the
performance of the subsidiaries. Furthermore, much of the Company's management
group has been assembled only recently, and a significant number of the
Company's management group has not worked in the HVAC, plumbing and electrical
service industries prior to joining the Company. There can be no assurance
that the management group will be able to manage the combined entity or to
implement effectively the Company's operating strategy, internal growth
strategy and acquisition program. The Company may experience delays,
complications and expenses in implementing, integrating and operating such
systems and in managing its businesses, any of which could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
DEPENDENCE ON ACQUISITIONS FOR GROWTH
 
  The Company intends to grow primarily by acquiring residential and
commercial contracting businesses that install or maintain, repair and replace
HVAC, plumbing, electrical and other systems and equipment in existing homes
and commercial buildings and in homes and commercial buildings under
construction in its existing and new markets. The Company's acquisition
strategy presents risks that, singly or in any combination, could materially
adversely affect the Company's business, financial condition and results of
operations. These risks include the possibility of the adverse effect on
existing operations of the Company from the diversion of management attention
and resources to acquisitions, the possible loss of acquired customer bases
and key personnel, including service technicians and managers, possible
adverse effects on earnings resulting from amortization of goodwill created in
purchase transactions and the contingent and latent risks associated with the
past operations and other unanticipated problems arising in the acquired
businesses. The success of the Company's acquisition strategy will depend on
the extent to which it is able to acquire, successfully absorb and profitably
manage additional businesses, and no assurance can be given that the Company's
strategy will succeed. The increasing competition for suitable acquisition
targets could limit the Company's ability to locate suitable acquisition
targets and could increase the cost of purchasing such acquisition targets.
 
EXPOSURE TO DOWNTURNS IN HOUSING STARTS OR NEW COMMERCIAL CONSTRUCTION
 
  A substantial portion of the Company's business involves installation of
HVAC and/or plumbing systems in newly constructed residences and commercial
buildings. The extent to which the Company is able to maintain or increase
revenues from new installation services in the residential market will depend
in part on the levels of housing starts from time to time in the geographic
markets in which it operates and likely will reflect the cyclical nature of
the housing industry. The housing industry is affected significantly by
changes in general and local economic conditions, such as employment and
income levels, the availability and cost of financing for home buyers
(including the continued deductibility of mortgage interest in determining
federal income tax), consumer confidence and housing demand. The level of new
commercial installation services is similarly affected by fluctuations in the
level of new construction of commercial buildings in the markets in which the
Company operates, due to local economic conditions, changes in interest rates
and other similar factors. Downturns in the
 
                                       4
<PAGE>
 
levels of housing starts and/or new commercial construction could have a
material adverse effect on the Company's business, financial condition and
results of operations. See"Management's Discussion and Analysis of Financial
Condition and Results of Operations--Seasonality and Cyclicality."
 
FLUCTUATION IN QUARTERLY OPERATING RESULTS
 
  The Company's operations are subject to economic cycles and seasonal
variations. General and local economic conditions can cause fluctuations in
demand for the Company's services. Except in the Southeastern and Southwestern
United States, the demand for new installations of HVAC systems can be
substantially lower during the winter months. Demand for HVAC services,
especially in the residential sector, is generally higher in the second and
third calendar quarters. Commercial HVAC maintenance, repair and replacement
service is subject to seasonality as well. The Company expects that its
revenues and operating results generally will be lower in its first and fourth
calendar quarters. The HVAC, electrical and plumbing service industries are
also subject to fluctuations caused by periods of inclement weather. Prolonged
climate or weather conditions may cause unpredictable fluctuations in
operating results. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Seasonality and Cyclicality."
 
AVAILABILITY OF TECHNICIANS
 
  The Company's ability to provide high-quality HVAC, plumbing and electrical
services on a timely basis requires an adequate supply of skilled technicians.
Accordingly, the Company's ability to increase its productivity and
profitability will be limited by its ability to employ, train and retain the
skilled technicians necessary to meet the Company's service requirements. From
time to time, there are shortages of qualified technicians, and there can be
no assurance that the Company will be able to maintain an adequate skilled
labor force necessary to operate efficiently, that the Company's labor
expenses will not increase as a result of a shortage in the supply of skilled
technicians or that the Company will not have to curtail its planned internal
growth as a result of labor shortages. See"Business--Centralized Support
Services--Employee Screening, Training and Development."
 
WEATHER
 
  The Company's service business tends to be adversely affected by moderate
weather patterns, with comparatively warm winters and cool summers generally
reducing the demand for the Company's maintenance, repair and replacement
services. Additionally, the Company's new installation business is adversely
affected by extremely cold weather and by the amount of precipitation that an
area receives during the construction season. Prolonged climate or weather
conditions may cause unpredictable fluctuations in operating results. The
Company's operations are also subject to seasonal variations. See"Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Seasonality and Cyclicality."
 
COMPETITION
 
  The HVAC, plumbing and electrical service industries are highly fragmented
with low barriers to entry. Therefore, these industries are very competitive
and are served principally by small, owner-operated private companies. Certain
of these smaller competitors have lower overhead cost structures and may be
able to provide their services at lower rates than the Company. The Company
believes the HVAC, plumbing and electrical service industries are subject to
rapid consolidation on both a national and a regional scale. Several
companies, in addition to the Company, have completed initial public
offerings, have begun consolidation efforts and have entered into some of the
Company's markets. Other companies, including unregulated affiliates of
electric and gas public utilities and HVAC equipment manufacturers, have
entered the industry and others may do so in the future. These consolidators
and other entrants may have greater financial resources, name recognition, or
other competitive advantages than the Company and may be willing to pay higher
prices than the Company for the same opportunities. Consequently, the Company
may encounter significant competition in its efforts to achieve its growth
objectives. See"Business--Competition."
 
                                       5
<PAGE>
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company's operations depend on the continuing efforts of its executive
officers and senior management personnel, and the Company will depend on the
senior management of significant businesses it acquires in the future. The
business of the Company could be affected adversely if any of these persons
does not continue in his or her management role with the Company and the
Company is unable to attract and retain qualified replacements.
 
DEPENDENCE ON ADDITIONAL CAPITAL FOR FUTURE GROWTH
 
  The Company historically has financed capital expenditures and acquisitions
primarily through the issuance of equity securities, secured bank borrowings
and internally generated cash flow. The timing, size and success of the
Company's acquisition efforts and the associated capital commitments cannot be
readily predicted. The Company currently intends to finance future acquisitions
by using shares of its Common Stock for a significant portion of the
consideration to be paid. If the Common Stock does not maintain a sufficient
market value, or if potential acquisition candidates are otherwise unwilling to
accept Common Stock as part of the consideration for the sale of their
businesses, the Company may be required to utilize more of its cash resources,
if available, in order to initiate and maintain its acquisition program. There
can be no assurance the Company will be able to raise sufficient capital at
reasonable rates, if at all. If the Company does not have sufficient cash
resources, its growth could be limited unless it is able to obtain additional
capital through debt or equity financing. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."
 
CONTROL BY EXISTING MANAGEMENT AND STOCKHOLDERS
 
  As of August 31, 1998, the executive officers, directors and 5% shareholders
of the Company will beneficially own in the aggregate approximately 21.9% of
GroupMAC's outstanding Common Stock. Accordingly, such persons will have
substantial influence on the Company, which influence might not be consistent
with the interests of other shareholders, and on the outcome of any matters
submitted to GroupMAC's shareholders for approval. In addition, although there
is no current agreement, understanding or arrangement for these shareholders to
act together on any matter, these shareholders may have economic and business
reasons to act together, and would be in a position to execute significant
influence over the affairs of the Company if they were to act together in the
future. If these persons were to act in concert, they might, as a practical
matter, be able to exercise control over the Company's affairs, including the
election of the entire Board of Directors and (subject to Article Thirteen of
the Texas Business Corporation Act (the "TBCA") which applies to transactions
between the Company and certain interested persons) any matter submitted to a
vote of shareholders.
 
POTENTIAL EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE ON PRICE OF COMMON STOCK
 
  As of August 31, 1998, 27,975,585 shares of Common Stock were outstanding.
The 8,340,000 shares sold in the IPO (other than shares that were purchased by
affiliates of the Company) are freely tradable. Additionally, the Company
registered under the Securities Act of 1933, as amended (the "Securities Act"),
approximately 725,000 shares in connection with the acquisition of MacDonald-
Miller Industries, Inc. ("MacDonald-Miller") and approximately 6.9 million
shares in connection with the acquisitions subsequent to the IPO. The remaining
shares outstanding may be resold publicly only following their effective
registration under the Securities Act or pursuant to an available exemption
(such as provided by Rule 144 following a holding period for unregistered
shares) from the registration requirements of the Securities Act. The holders
of approximately 3.6 million shares of Common Stock have the right (subject to
minimum participation requirements) to require the Company to register such
shares pursuant to the Securities Act for the purpose of allowing them to
effect a public offering of all or a portion of such shares (a "Demand
Registration"), and such holders and substantially all of the other holders of
unregistered shares of Common Stock also have the right to require the Company
to register their shares of Common Stock under the Securities Act in connection
with a public offering of Common Stock contemplated by the Company (a
"Piggyback Registration"). The number of Demand Registrations that may be

requested is limited, and the Company will not be obligated to effect a Demand
Registration within 60 days prior to the proposed filing date of a registration
statement relating to an offering by the Company of its securities (with
certain exceptions) or within 120 days after the effective date of such a
registration statement. Further, the Company may delay a Demand Registration
for up to 120 days if the Company determines that such registration would be
detrimental to the Company. In connection with a Piggyback Registration
involving an underwritten offering, the number of shares to be registered by
selling shareholders may be limited or eliminated entirely if the managing
underwriter determines marketing factors require a limitation on the number of
shares to be underwritten. See "Shares Eligible for Future Sale." The holders
of Demand Registration rights have agreed with the Company and the underwriters
of the Company's IPO (the "Underwriters") not to exercise their respective
demand rights for the two year period following the IPO except for Gordon A.
Cain who has agreed not to exercise his demand rights for one year. In
addition, such holders and the holders of Common Stock issued in connection
with the acquisition of businesses have agreed with the Company that they
generally will not sell, transfer or otherwise dispose of any of their shares
for one year following the date of acquisition of such shares and for one
additional year will limit sales to no more than 36% of their holdings. Sales
made pursuant to Rule 144 must comply with its applicable volume limitations
and other requirements. At the date of this Prospectus, approximately 9.5
million "restricted" shares of Common Stock are eligible for resale pursuant to
Rule 144, subject to the volume, manner of sale and other limitations thereof
and the remaining "restricted" shares will become eligible for resale pursuant
to Rule 144 from time to time thereafter.
 
  The Company has outstanding options and warrants to purchase up to a total of
approximately 3.7 million shares of Common Stock, of which only warrants and
options to purchase approximately 1.5 million shares are exercisable within 60
days after the date of this Prospectus. The Company has registered the shares
subject to these options (but not the 514,000 shares subject to the warrants)
under the Securities Act for public resale.
 
  The effect, if any, of the availability for sale, or sale, of the shares of
Common Stock eligible for future sale on the market price of the Common Stock
prevailing from time to time is unpredictable, and no assurance can be given
that the effect will not be adverse.
 
RESTRICTIONS ON DIVIDENDS; DEPENDENCE ON SUBSIDIARIES
 
  The Company will conduct its operations through subsidiaries, and is
therefore dependent upon the cash flow of and the transfer of funds by those
subsidiaries to the Company in the form of loans, dividends or otherwise to
meet its financial obligations. Each subsidiary of the Company will be a
distinct legal entity and will have no obligation, contingent or otherwise, to
transfer funds to the Company. The Company's ability to pay dividends on the
Common Stock is restricted by the terms of its $125 million bank credit
facility (the "Credit Agreement") and could be restricted by the terms of
subsequent financings and subsequent series of preferred stock that may be
issued in future transactions. See "Description of Capital Stock."
Additionally, the ability of the Company's subsidiaries to pay dividends to the
Company is limited by the terms of the Credit Agreement. See "Description of
Credit Agreement."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
  Prior to the IPO, no public market for the Common Stock existed. The market
price of the Common Stock may be subject to significant fluctuations from time
to time in response to numerous factors, including variations in the reported
financial results of the Company and changing conditions in the economy in
general or in the Company's industry in particular. In addition, stock markets
generally experience significant price and volume volatility from time to time
which may affect the market price of the Common Stock for reasons unrelated to
the Company's performance.
 
POTENTIAL ANTI-TAKEOVER EFFECTS
 
  Provisions of the Company's Articles of Incorporation and Bylaws and the TBCA
may have the effect of delaying, discouraging, inhibiting, preventing or
rendering more difficult an attempt to obtain control of the
 
                                       7
<PAGE>
 
Company by means of a tender offer, business combination, proxy contest or
otherwise. These provisions include the authorization in the Company's Articles
of Incorporation of preferred stock having such preferences, powers and
relative, participating, optional and other rights (including preferences over
the Common Stock respecting dividends, distributions and voting rights) as the
Board of Directors may determine, classification of the Board of Directors, a
TBCA restriction on the ability of shareholders to take actions by written
consent and a TBCA provision imposing restrictions on business combinations
with certain interested parties. See "Description of Capital Stock."
 
ASSET ENCUMBRANCE
 
  The obligations of the Company under the Credit Agreement are secured by a
first priority security interest on substantially all of the accounts
receivable and inventory of the Company and its material subsidiaries and on
the capital stock of most of its domestic subsidiaries. In addition, borrowings
under the Credit Agreement have been guaranteed by the Company's material
subsidiaries, and must be guaranteed by any future material subsidiaries. If
the Company becomes insolvent or is liquidated, if there were a breach of the
restrictions in the Credit Agreement so as to result in a default thereunder or
if the Company were unable to repay its borrowings thereunder, lenders under
the Credit Agreement could declare all amounts outstanding thereunder to be due
and payable and the obligations of the lenders to make further extensions of
credit could be terminated. The lenders under the Credit Agreement also would
be entitled to proceed against the collateral securing such indebtedness.
Accordingly, such lenders would have a prior claim on certain assets of the
Company and its subsidiaries. See "Description of Credit Agreement."
 
OTHER FACTORS
 
  In addition to the factors described above, the Company may be impacted by a
number of other matters and uncertainties, including: (i) potential legislation
or regulatory changes; (ii) the ability of the Company and those with which it
conducts business to timely resolve the Year 2000 issue (relating to potential
computer and equipment failures by or at the change in the century),
unanticipated costs of resolving the Year 2000 issue, and the costs and impacts
if the Year 2000 issue is not timely resolved; (iii) changes in competitive
conditions in the markets where the Company operates; (iv) changes in capital
availability or costs, changes in interest rates, or market perceptions of the
industries in which the Company operates; (v) increases in the cost of
compliance with regulations, including environmental regulations, and
environmental liabilities; (vi) incurrence of losses arising from the risks
normally associated with the Company's business in excess of the insurance
coverage maintained by the Company; and (vii) changes by the Financial
Accounting Standards Board or the Securities and Exchange Commission of
authoritative generally accepted accounting principles or policies.
 
FORWARD-LOOKING STATEMENTS
 
  Certain of the statements contained in this Prospectus may be considered
forward-looking statements within the meaning of Section 27A of the Securities
Act and Section 21E of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), that are based on management's beliefs, as well as assumptions
made by, and information currently available to, management. When used herein,
words such as "anticipate," "estimate," "expect," "objective," "projection,"
"forecast," "goal" or similar words are intended to identify forward-looking
statements. Although the Company believes that the expectations reflected in
such forward-looking statements are reasonable, it can give no assurance that
such expectations will prove to have been correct. Such statements are subject
to certain risks, uncertainties and assumptions. Should one or more of these
risks or uncertainties materialize, or should underlying assumptions prove
incorrect, actual results may vary materially from those anticipated,
estimated, projected or expected. Important factors that could cause future
results to differ include the effects of competition, legislative and
regulatory changes, fluctuations in the weather and changes in the economy.

Stock Exchange was $13 7/16 and there were 414 holders of record of Common
Stock, as shown on the records of the transfer agent and registrar for the
Common Stock. The number of record holders does not bear any relationship to
the number of beneficial owners of the Common Stock. The Company has never
declared a dividend with respect to its Common Stock.

                                DIVIDEND POLICY
 
  The Company has not paid a dividend on Common Stock since its incorporation
and does not anticipate paying any dividends on Common Stock in the
foreseeable future because it intends to retain earnings to finance the
expansion of its business, to repay indebtedness and for general corporate
purposes. Any payment of future dividends will be at the discretion of the
Board of Directors and will depend upon, among other things, the Company's
earnings, financial condition, capital requirements, level of indebtedness,
contractual restrictions with respect to the payment of dividends and other
relevant factors. The Credit Agreement restricts the payment of dividends. See
"Description of Credit Agreement."

               SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA
 
  The first and largest acquisition made by the Company was that of Airtron,
Inc. ("Airtron"). For accounting purposes, this transaction was accounted for
as a reverse acquisition, as if Airtron acquired GroupMAC, because the former
shareholders of Airtron owned a majority of GroupMAC's Common Stock upon
consummation of the transaction. As such, the summary historical financial
data set forth below as of and for the three-year period ended February 28,
1997 have been derived from the financial statements of Airtron, which have
been audited by KPMG Peat Marwick LLP, independent public accountants. The
financial statements of GroupMAC and its subsidiaries, other than Airtron, as
of June 30, 1997 and 1998 and December 31, 1997, are included in the financial
statements from their respective dates of acquisition. The consolidated
financial statements of the Company as of December 31, 1997 and February 28,
1997, and for each of the periods then ended and the year ended February 29,
1996, and the report thereon, are included elsewhere herein. The historical
financial data of the Company as of June 30, 1998 and for the six month
periods ended June 30, 1997 and 1998 are derived from the Company's unaudited
financial statements included elsewhere herein. In the opinion of the
Company's management, the financial statements for June 30, 1997 and 1998
include all adjusting entries (consisting only of normal recurring
adjustments) necessary to present fairly the information set forth herein.
 
  The selected pro forma financial data presents certain information for the
Company, as adjusted for (i) the effects of the acquisitions of Airtron, 10
other companies (the "Pre-IPO Companies") purchased during June and July 1997
and 13 additional companies (the "IPO Companies" and, together with Airtron
and the Pre-IPO Companies, the "Founding Companies") purchased concurrently
with the IPO, (ii) the effects of the acquisition of 15 companies in the first
quarter of 1998 (the "First Quarter Post-IPO Companies") and the effects of
the acquisition of 12 companies in the second quarter of 1998 (the "Second
Quarter Post-IPO Companies") and the effects of the acquisition of eight
companies in the third quarter of 1998 (the "Third Quarter Post-IPO
Companies", and together with the First Quarter Post-IPO Companies and the
Second Quarter Post-IPO Companies, the "Post-IPO Companies", and together with
the Founding Companies, the "GroupMAC Companies"), and (iii) the effects of
certain pro forma adjustments to the historical financial statements of the
GroupMAC Companies which are directly related to these acquisitions. The
selected pro forma financial data of the Company do not purport to represent
what the Company's results of operations or financial position actually would
have been had these events, in fact, occurred on the assumed date, nor are
they intended to project the Company's results of operations or financial
position for any future date or period.
 
  The selected financial data presented below should be read in conjunction
with "Management's Discussion and Analysis of Financial Condition and Results
of Operations" and the financial statements and the related notes and the
unaudited pro forma combined financial statements and the related notes
included elsewhere herein.

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
GENERAL
 
  The Company's revenues are derived from providing maintenance, repair and
replacement and new installation services for HVAC, electrical, plumbing and
other systems to residential and commercial customers. Approximately 44% of
the Company's combined 1997 revenues of $782.2 million were derived from new
installation services and 56% were attributable to maintenance, repair and
replacement services. Maintenance, repair and replacement revenues are
recognized as the services are performed, except for service contract revenue,
which is recognized ratably over the life of the contract. Revenues from fixed
price installation and retrofit contracts are generally accounted for on a
percentage-of-completion basis, using the cost-to-cost method.
 
  The Company intends to make additional acquisitions across the three main
technical disciplines (HVAC, electrical and plumbing) within the residential
and commercial markets. The Company's long-term objective is to develop
maintenance, repair and replacement capabilities (both residential and
commercial) in the top 100 markets within the United States, while offering
new installation services across a more limited range of markets where new
construction in the residential and/or commercial sectors is expected to out-
pace the national average over the long term. Over time, this objective is
expected to shift revenues of the Company to an increased percentage of
service revenue.
 
  Cost of services consists primarily of components, parts and supplies
related to the Company's new installation and maintenance, repair and
replacement services, salaries and benefits of service and installation
technicians, subcontracted services, depreciation, fuel and other vehicle
expenses and equipment rentals. Selling, general and administrative expenses
consist primarily of compensation and related benefits for prior owners,
administrative salaries and benefits, advertising, office rent and utilities,
communications and professional fees.
 
  The Company's diversified business mix is reflected to varying degrees in
its gross margins. The Company's businesses performing primarily maintenance,
repair and replacement services in the residential markets tend to have higher
gross margins, averaging 32.4% for the combined twelve months ended December
31, 1997. The combined gross margin for the GroupMAC Companies providing
primarily maintenance, repair and replacement services in the commercial
markets was 21.8% for the combined twelve months ended December 31, 1997. On
average, the GroupMAC Companies primarily engaged in residential new
installation services have lower gross margins. Such companies' combined gross
margin was 21.0% for the combined twelve months ended December 31, 1997. The
companies primarily providing HVAC services in the residential new
installation market had an average gross margin of 27.6%, which was somewhat
offset by the companies providing primarily plumbing service to this market at
an average gross margin of 12.9%. Future consolidated gross margins may vary
depending on, among other things, shifts in the business mix within the
GroupMAC Companies as well as the impact of future acquisitions on the
business mix.
 
  The Company has begun to realize savings from (i) greater volume discounts
from suppliers of components, parts and supplies; (ii) consolidation of
insurance and bonding programs; (iii) other general and administrative
expenses such as training and advertising; and (iv) the Company's ability to
borrow at lower interest rates than most, if not all, of the GroupMAC
Companies. Offsetting these savings are costs related to the Company's new
corporate management, costs associated with being a public company and
integration costs.
 
  The following discussion should be read in conjunction with the historical
financial statements and related notes and "Selected Historical and Pro Forma
Financial Data" contained elsewhere herein.
 
RESULTS OF OPERATIONS--GROUPMAC AND SUBSIDIARIES
 
  Effective April 30, 1997, GroupMAC entered into an Agreement and Plan of
Exchange (the "Agreement") with Airtron, in which $20.8 million in cash, 14.9
million shares of GroupMAC preferred stock and 4.7 million shares of GroupMAC
Common Stock were issued to shareholders of Airtron in exchange for all of the
then outstanding shares of Airtron. Although for legal purposes Airtron was
acquired by GroupMAC, for accounting
 
                                      13
<PAGE>
 
purposes, the transaction was accounted for as a reverse acquisition, as if
Airtron acquired GroupMAC, due to the fact that the former shareholders of
Airtron then owned a majority of the outstanding GroupMAC Common Stock. In
connection with the purchase of GroupMAC, the consideration paid to the
shareholders of GroupMAC was recorded as non-recurring compensation expense of
$7.0 million in the accompanying statements of operations for the ten months
ended December 31, 1997. The consolidated financial statements presented
elsewhere herein for the periods prior to the effective date of the
acquisition only include the accounts of Airtron. The consolidated statements
of shareholders' equity have been converted from Airtron's capital structure
to GroupMAC's capital structure to reflect the exchange of shares pursuant to
the Agreement. Concurrent with the IPO, the Company changed its fiscal year
end from February 28 to December 31.
 
  During June and July 1997, the Company acquired in separate transactions the
Pre-IPO Companies through a combination of cash, preferred stock, Common Stock
and warrants to purchase shares of Common Stock of GroupMAC. During the fourth
quarter of 1997, the Company acquired, concurrently with the IPO, the IPO
Companies through a combination of cash and Common Stock of the Company.
During the first, second and third quarters of 1998 the Company acquired the
Post-IPO Companies through a combination of Common Stock, options to purchase
Common Stock and cash.
 
  The following table sets forth certain financial data for the periods
indicated (dollars in thousands):

 Twelve Months Ended February 28, 1997 Compared to Twelve Months Ended
February 29, 1996
 
  Revenues. Revenues increased $8.1 million, or 11.0%, to $81.9 million for
the twelve months ended February 28, 1997 from $73.8 million for the twelve
months ended February 29, 1996. The increase in revenues was attributable to
increased market penetration in new residential construction in the
Indianapolis, Indiana and Dallas, Texas markets, resulting in a larger volume
of new home starts.
 
  Gross Profit. Gross profit increased $2.3 million, or 10.9%, to $23.4
million for the twelve months ended February 28, 1997 from $21.1 million for
the twelve months ended February 29, 1996. Gross profit margin remained
relatively constant at 28.5% and 28.6% for the twelve months ended February
28, 1997 and February 29, 1996, respectively.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $2.2 million, or 12.5%, to $19.8 million for
the twelve months ended February 28, 1997 from $17.6 million for the same
period ended February 29, 1996. Such increase was primarily attributable to an
increase in compensation, vehicle leases and professional fees of the Company.
As a percentage of revenues, selling, general and administrative expenses
remained relatively constant at 24.1% and 23.9% for the twelve months ended
February 28, 1997 and February 29, 1996, respectively.
 
                                      14
<PAGE>
 
  Income Tax Provision. The income tax provision decreased $0.1 million, or
5.9%, to $1.6 million for the twelve months ended February 28, 1997 from $1.7
million for the same period ended February 29, 1996. The effective tax rate
for the twelve months ended February 28, 1997 was 40.2% compared to 43.6% for
the same period ended February 29, 1996. The decrease in the effective tax
rate was due to a higher state income tax provision for the twelve months
ended February 29, 1996.
 
 Ten Months Ended December 31, 1997 Compared to Twelve Months Ended February
28, 1997
 
  Revenues. Revenues increased $56.6 million, or 69.1%, to $138.5 million for
the ten months ended December 31, 1997 from $81.9 million for the twelve
months ended February 28, 1997. The increase in revenues was attributable to
the acquisitions of the Pre-IPO Companies in June and July of 1997 and the
acquisitions of the IPO Companies during November 1997. The increase in
revenues was partially offset as the period ended December 31, 1997 included
ten months while the period ended February 28, 1997 included twelve months.
 
  Gross Profit. Gross profit increased $13.3 million, or 56.8%, to $36.7
million for the ten months ended December 31, 1997 from $23.4 million for the
twelve months ended February 28, 1997. The increase in gross profit was
primarily attributable to the acquisitions of the Pre-IPO Companies in June
and July of 1997, the acquisitions of the IPO Companies during November 1997
and lower material costs at Airtron. The increase in gross profit was
partially offset as the period ended December 31, 1997 included ten months
while the period ended February 28, 1997 included twelve months. Gross profit
margin decreased 2.0% for the ten months ended December 31, 1997 compared to
the twelve months ended December 31, 1997 because certain of the Founding
Companies' gross profit margins were considerably lower than those achieved at
Airtron.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $16.7 million, or 84.3%, to $36.5 million
for the ten months ended December 31, 1997 from $19.8 million for the twelve
months ended February 28, 1997. Such increase was primarily attributable to
(i) a $7.0 million non-recurring non-cash compensation charge related to the
reverse acquisition of GroupMAC in May 1997, (ii) a $0.2 million non-
recurring, non-cash compensation charge related to the issuance of management
shares and options, (iii) the aforementioned acquisitions and (iv) a $4.1
million increase in corporate expenses representing the formation of the
corporate management team and infrastructure necessary to execute the
Company's operating and acquisition strategies. As a percentage of revenues,
selling, general and administrative expenses, excluding the aforementioned
items, decreased to 17.5% for the ten months ended December 31, 1997 from
24.1% for the twelve months ended February 28, 1997, respectively, due
primarily to prospective reductions in compensation to former owners, to which
they agreed. These reductions in salaries are in accordance with the terms of
their employment agreements.
 
  Net Interest. Net interest was an expense of $1.1 million for the ten months
ended December 31, 1997. For the twelve months ended February 28, 1997, net
interest income was $0.1 million. Interest charges increased during the ten
months ended December 31, 1997 due to borrowings under the Company's credit
facilities to fund the cash portion of the acquisition of Airtron and the Pre-
IPO Companies. See "Liquidity and Capital Resources."
 
  Income Tax Provision. The income tax provision increased $1.2 million, or
75.0%, to $2.8 million for the ten months ended December 31, 1997 from $1.6
million for the twelve months ended February 28, 1997 while pre-tax income
decreased $4.7 million. Excluding the effect of the $7.2 million non-
deductible compensation charge discussed above, the effective tax rate for the
ten months ended December 31, 1997 was 44.2% compared to 40.2% for the twelve
months ended February 28, 1997, resulting primarily from the non-deductible
goodwill amortization of $0.6 million in the ten months ended December 31,
1997.
 
 Six Months Ended June 30, 1998 Compared to Six Months Ended June 30, 1997
 
  Revenues. Revenues increased $223.4 million to $266.3 million for the six
months ended June 30, 1998 from $42.8 million for the six months ended June
30, 1997. Such increase in revenues included $216.7 million attributable to
the acquisitions of the Pre-IPO Companies in June and July of 1997, the
acquisitions of the IPO Companies during November 1997 and the acquisitions of
the Post-IPO Companies during the six months ended June 30, 1998. Also
contributing to the increase was a $6.7 million increase in revenues at
Airtron, which related to strong housing starts throughout the country,
particularly in the Midwestern and South Central United States.
 
                                      15
<PAGE>
 
  Gross Profit. Gross profit increased $51.8 million to $63.7 million for the
six months ended June 30, 1998 from $11.9 million for the six months ended
June 30, 1997. Such increase in gross profit included approximately $0.9
million in materials purchases savings and $49.3 million attributable to the
acquisitions of the Pre-IPO Companies in June and July of 1997, the
acquisitions of the IPO Companies during November 1997 and the acquisitions of
the Post-IPO Companies during the six months ended June 30, 1998. Gross profit
at Airtron increased by $1.6 million between periods, with virtually all of
that increase occurring in the second quarter. This increase did not correlate
as favorably with Airtron's $6.7 million increase in revenues as a higher mix
of lower margin new installation work occurred in the first quarter as a
result of a reduction in maintenance, repair and replacement sales due to
adverse weather patterns, particularly in the Midwestern United States. Gross
profit margin decreased 3.9% to 23.9% for the six months ended June 30, 1998
compared to 27.8% for the six months ended June 30, 1997 because certain of
the GroupMAC Companies' gross profit margins were considerably lower than
those achieved at Airtron.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $29.7 million to $47.7 million for the six
months ended June 30, 1998 from $18.0 million for the six months ended June
30, 1997. Such increase included $31.2 million attributable to the
acquisitions of the Pre-IPO Companies in June and July of 1997, the
acquisitions of the IPO Companies during November 1997 and the acquisitions of
the Post-IPO Companies during the six months ended June 30, 1998. Also
contributing to the increase was a $3.5 million increase in corporate expenses
representing the formation of the corporate management team and infrastructure
necessary to execute the Company's operating and acquisition strategies and
$2.0 million of goodwill amortization. Offsetting the increases was a $7.0
million reduction in compensation expense recognized in the prior year from
the reverse acquisition of Airtron. As a percentage of revenues, selling,
general and administrative expenses, excluding corporate expenses, goodwill
amortization and 1997 non-recurring compensation expense, decreased to 15.6%
for the six months ended June 30, 1998 from 24.3% for the six months ended
June 30, 1997, respectively, due primarily to the prospective reductions in
compensation to former owners of Airtron. When including corporate expenses
and goodwill amortization, but excluding the non-recurring compensation
expense of $7.0 million related to the reverse acquisition, selling, general
and administrative expenses as a percentage of revenue decreased to 17.9% for
the six months ended June 30, 1998 from 25.8% for the six months ended June
30, 1997.
 
  Net Interest. Net interest increased $0.8 million during the six months
ended June 30, 1998 compared to the same period of the prior year. Such
increase was attributable to a higher level of borrowings under the Company's
credit facility. See "Liquidity and Capital Resources."
 
  Income Tax Provision. The income tax provision increased $6.3 million to
$6.7 million for the six months ended June 30, 1998 from $0.4 million for the
six months ended June 30, 1997. This increase corresponds with the pretax
income increase of $14.2 million between periods after adding back the $7.0
million of compensation expense related to the reverse acquisition of Airtron.
The effective tax rate for the six months ended June 30, 1998 was 44.5%
compared to 41.6% for the six months ended June 30, 1997 after adding back the
$7.0 million of compensation expense related to the reverse acquisition of
Airtron. This increase results primarily from the non-deductible goodwill
amortization of $2.0 million in the six months ended June 30, 1998.

 Nine Months Ended September 30, 1997 Compared to Nine Months Ended
 September 30, 1996
 
  Revenues. Revenues increased $2.4 million, or 4.6%, from $52.2 million for
the nine months ended September 30, 1996 to $54.6 million for the nine months
ended September 30, 1997. The increase in revenues was attributable to
continuing strength in the company's Northwest commercial markets, principally
Seattle, Washington and Portland, Oregon, including a $20 million contract
with a large software company to be completed in 1997, an increase in revenues
from the company's Special Projects and Tenant Improvement operations, and an
increase in revenues from the company's Commercial Service operations.
 
  Gross Profit. Gross Profit increased $1.2 million, or 17.1%, from $7.0
million for the nine months ended September 30, 1996 to $8.2 million for the
nine months ended September 30, 1997. Gross margin increased from 13.4% for
the first nine months of 1996 to 15.0% for the same period of 1997. The gross
profit increase was attributable principally to higher volume and realized
gross margins in the MacDonald-Miller's Special Projects and Tenant
Improvement operations.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $0.6 million, or 10.7%, from $5.6 million
for the nine months ended September 30, 1996 to $6.2 million for the nine
months ended September 30, 1997. Both the dollar and percentage of revenue
changes were attributable to the higher revenue levels in 1997 compared to
1996. As a percentage of revenues, selling, general and administrative
expenses increased slightly from 10.7% for the nine months of 1996 to 11.5%
for the same period of 1997.
 
 Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
  Revenues. Revenues increased $20.6 million, or 45.3%, from $45.5 million for
the year ended December 31, 1995 to $66.1 million for the year ended December
31, 1996. The increase in revenues was attributable to a 15%, or $1.6 million,
increase in revenues from Service and Maintenance operations, and a 23%, or
$2.0 million, increase in revenues from the company's Special Projects and
Tenant Improvement operations. The $17 million balance of the increase was
attributable to contracted design and build projects, HVAC system retrofits
and remodels, lighting energy retrofits and technical services, together
representing a revenue increase of 65.4% over 1995. This increase was
primarily volume driven and directly related to the company's effort to
increase its market presence in the Seattle, Washington and Portland, Oregon
metropolitan areas, fueled by continued strength of commercial activity in the
Northwest.
 
  Gross Profit. Gross profit increased $1.1 million, or 12.8%, from $8.6
million for the year ended December 31, 1995 to $9.7 million for the year
ended December 31, 1996. Gross margin decreased from 18.9% to 14.7% due to the
acceptance of certain lower margin projects and increased direct costs related
to the rapid revenue growth experienced in 1996.

  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $0.3 million, or 4.1%, from $7.3 million for
the year ended December 31, 1995 to $7.6 million for the year ended December
31, 1996. The increase in these expenses was directly attributable to
incremental costs incurred to implement a job cost and accounting software
conversion and other management information systems processes and
infrastructure. As a percentage of revenues, selling, general and
administrative expenses decreased from 16.2% to 11.6% due to the increased
revenue levels.

 Nine Months Ended September 30, 1997 Compared to Nine Months Ended
 September 30, 1996
 
  Revenues. Revenues increased $2.1 million, or 7.2%, from $29.1 million for
the nine months ended September 30, 1996 to $31.2 million for the nine months
ended September 30, 1997. The increase in revenues was primarily attributable
to an additional volume of housing starts generated from existing customers.
 
  Gross Profit. Gross profit increased $0.4 million, or 14.3%, from $2.8
million for the nine months ended September 30, 1996 to $3.2 million for the
nine months ended September 30, 1997. Gross margin increased from 9.6% for the
nine months ended September 30, 1996 to 10.3% for the nine months ended
September 30, 1997. The increase was primarily attributable to a higher mix of
fire sprinkler installations that typically produce higher margins.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $0.3 million, or 17.6%, from $1.7 million
for the nine months ended September 30, 1996 to $2.0 million for the nine
months ended September 30, 1997. The increase in selling, general and
administrative expenses was primarily due to staff additions to keep pace with
the growth of the company, increased bad debts and an increase in professional
fees. As a percentage of revenues, selling, general and administrative
expenses increased from 6.0% to 6.5% over the respective periods.
 
 Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
  Revenues. Revenues increased $4.6 million, or 13.1%, from $35.2 million for
the year ended December 31, 1995 to $39.8 million for the year ended December
31, 1996. The increase was attributable to an additional volume of housing

1996. As a percentage of revenues, selling, general and administrative
expenses decreased from 6.7% to 6.3% over the same period. This decrease was
primarily attributable to the net increase in revenue and the relatively fixed
nature of these expenses.

for the six months ended June 30, 1996 to $1.7 million for the six months

  Revenues. Revenues increased $1.6 million, or 7.0%, from $22.7 million for
the year ended March 31, 1996 to $24.3 million for the year ended March 31,
1997. The increase in revenues was primarily volume driven and attributable to
the expansion of the Company's customer base to include several new home

million for the year ended March 31, 1996 to $3.6 million for the year ended
March 31, 1997. The increase was due to a decline in production labor and
material costs for start ups in Austin, Texas and Las Vegas, Nevada, and the
savings from the closing during fiscal 1996 of an unsuccessful operation in
Palmdale, California. Gross margin increased from 10.4% to 14.7% for the years
ending March 31, 1996 and 1997, respectively.

  Revenues. Revenues increased $1.2 million, or 5.6%, from $21.5 million for
the year ended March 31, 1995 to $22.7 million for the year ended March 31,

metropolitan area.
 
  Gross Profit. Gross Profit decreased $256,000, or 9.8%, from $2.6 million
for the year ended March 31, 1995 to $2.4 million for the year ended March 31,
1996. Gross margin decreased from 12.2% to 10.4% for the years ended March 31,
1995 and 1996, respectively. The gross margin decline was primarily
attributable to aggressive pricing and start-up labor costs for the two new
divisions in Austin, Texas and Las Vegas, Nevada.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $203,000, or 8.8% from $2.3 million for the
year ended March 31, 1995 to $2.5 million for the year ended March 31, 1996.
The increase in selling, general and administrative expenses was primarily
attributable to incremental costs relating to the closing of the Palmdale,
California operation and the implementation of a new management information
system. As a percentage of revenues, selling, general and administrative
expenses increased slightly from 10.6% to 10.9%.

replacement business, an increase in replacement sales at Willis and the
occurrence of a significant light commercial job at Jarrell.
 
  Gross Profit. Gross profit increased $1.6 million, or 18.8%, from $8.5
million for the six months ended June 30, 1996 to $10.1 million for the six
months ended June 30, 1997. Gross margin increased from 36.5% to 40.5% from
the six month period ended June 30, 1996 to the corresponding period in 1997.
The increase in gross margin was attributable to higher margins at Central
Carolina from operational efficiencies and from increased higher margin
replacement sales at Willis.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $195,000, or 2.4%, from $8.1 million for the
six months ended June 30, 1996 to $8.3 million for the six months ended June
30, 1997. As a percentage of revenues, selling, general and administrative
expenses decreased from 34.7% to 33.2% for the six month period ended June 30,
1996 compared to the corresponding period in 1997.
 
 Fiscal 1996 Compared to Fiscal 1995
 
  Revenues. Revenues increased $5.8 million, or 13.4%, from $43.2 million in
fiscal 1995 to $49.0 million in fiscal 1996. The increase in revenues was
primarily volume driven and attributable to the continued internal expansion
of HVAC services to an appliance company acquired by A-ABC in late 1994, an
acquisition made during early 1996 by Hallmark of an operation in San Antonio
and an aggressive advertising campaign at Costner. Also, revenues increased
significantly at Van's and Willis due to a higher level of replacement sales.
 
  Gross Profit. Gross profit increased $2.6 million, or 16.6%, from $15.7
million in fiscal 1995 to $18.3 million in fiscal 1996. The increase in gross
profit was attributable to the continued internal expansion of HVAC
 
                                      22
<PAGE>
 
services at A-ABC, an acquisition by Hallmark of a high margin operation in
San Antonio and revenue increases at Costner and other higher margin
companies. Gross margin increased from 36.3% to 37.4% for fiscal 1995 and
1996, respectively.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $2.3 million, or 16.2%, from $14.2 million
in fiscal 1995 to $16.5 million in fiscal 1996. The increase in selling,
general and administrative expenses was mainly due to the acquisition of an
operation in San Antonio by Hallmark during the period, a higher level of
spending on advertising at Costner and an increase in owner compensation among
all of the residential service companies of $116,000. As a percentage of
revenues, selling, general and administrative expenses increased from 32.9% to
33.7% for fiscal 1995 and 1996, respectively.

 Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996
 
  Revenues. Revenues declined $590,000, or 2.4%, from $24.5 million for the
six months ended June 30, 1996 to $23.9 million for the six months ended June
30, 1997. The decrease in revenues was primarily volume driven and
attributable to a $2.0 million decline in revenues at Sibley which resulted
from an internal decision to discontinue a large, low margin customer
relationship. Such decline was offset by growth at Linford from incremental
service agreements and at Mechanical Services from incremental "design and
build" project work.
 
  Gross Profit. Gross profit declined $192,000, or 2.9%, from $6.9 million for
the six months ended June 30, 1996 to $6.7 million for the six months ended
June 30, 1997. The decline in gross profit primarily resulted from the
discontinuance of the customer relationship discussed above. Gross margin
remained consistent at 28.1% and 28.0% for the six month periods ended June
30, 1996 and 1997, respectively.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $494,000, or 10.6%, from $4.7 million for
the six months ended June 30, 1996 to $5.2 million for the six months ended
June 30, 1997. The increase in selling, general and administrative expenses
was primarily attributable to incremental owners' compensation and additional
personnel to support the growth in sales at Linford and an intentional shift
in business mix at Yale toward higher margin service contract work. As a
percentage of revenues, selling, general and administrative expenses increased
from 19.2% to 21.7% over the six month periods ended June 30, 1996 and 1997,
respectively.

 Fiscal 1996 Compared to Fiscal 1995
 
  Revenues. Revenues increased $8.0 million, or 20.8%, from $38.5 million in
fiscal 1995 to $46.5 million in fiscal 1996. The increase in revenues was
primarily volume driven and attributable to incremental service agreements at
Linford, incremental design and build projects at Mechanical Services and an
increase in maintenance, repair and replacement sales at Southeast Mechanical
and Sibley Services.
 
  Gross Profit. Gross profit increased $1.8 million, or 16.5%, from $10.9
million in fiscal 1995 to $12.7 million in fiscal 1996. The largest factor
impacting the increase in gross profit was volume growth in revenues at
Linford, although the growth was at slightly lower margins. Additionally,
significant increases in gross profit were due to rapid service revenue growth
combined with margin expansion at All Service and Yale. Gross margin decreased
slightly from 28.2% to 27.2% between fiscal 1995 and fiscal 1996.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $1.3 million, or 14.3%, from $9.1 million in
fiscal 1995 to $10.4 million in fiscal 1996. The overall increase in selling,
general and administrative expenses was due to the expansion and relocation of
facilities as well as an increase in administrative and sales personnel at
Linford. As a percentage of revenues, selling, general and administrative
expenses decreased slightly from 23.7% to 22.3% in fiscal 1996.

JUNE 30, 1997 AND 1998:
 
Combined Six Months Ended June 30, 1998 Compared to Combined Six Months Ended
June 30, 1997
 
  Revenues. Combined revenues increased $24.6 million, or 6.6%, to $395.8
million for the six months ended June 30, 1998 from $371.2 million for the six
months ended June 30, 1997. The increase in combined revenues was attributable
to (i) the companies that primarily provide residential new installation
services which experienced a 17.3% increase in revenues due to an increase in
new home starts in the markets they serve, (ii) the companies that primarily
provide residential maintenance, repair and replacement services which
experienced a 15.2% increase due to favorable weather patterns in the markets
they serve and (iii) a slight increase of 2.2% from the companies that
primarily provide commercial services.
 
  Gross Profit. Combined gross profit increased $6.5 million, or 7.6%, to
$91.8 million for the six months ended June 30, 1998 from $85.3 million for
the six months ended June 30, 1997. The increase in gross profit was
attributable to the increase in combined revenues described above. Gross
profit margin increased to 23.2% for the six months ended June 30, 1998
compared to 23.0% for the six months ended June 30, 1997. The increase in
gross profit margin was a result of (i) a higher volume of new home starts in
the current year, allowing the Company to operate at full capacity and thus
increase margins, (ii) a greater mix of higher margin maintenance, repair and
replacement business in the residential sector, and (iii) purchasing synergies
experienced in the current year. Offsetting the increase from these items was
a slight decline in gross profit in the commercial sector.
 
  The above discussion should be read in conjunction with the unaudited pro
forma combined financial statements and related notes contained elsewhere
herein. The pro forma combined financial data do not purport to represent what
the Company's results of operations would actually have been if such
transactions had in fact occurred on January 1, 1997 and are not necessarily
representative of the Company's results of operations for any future period.
Since the acquisitions have not historically been under common control or
management, historical pro forma combined results may not be indicative of or
comparable to future performance.
 
YEAR 2000
 
  Background. The Year 2000 issue refers to the inability of certain date-
sensitive computer chips, software and systems to recognize a two-digit date
field as belonging to the 21st century. Many computer software programs, as
well as certain hardware and equipment containing date sensitive data, were
structured to utilize a two-digit date field. Accordingly, these programs may
not be able to properly recognize dates in the year 2000 and later, which
could result in significant system and equipment failures. This is a
significant issue for most if not all companies, with far reaching
implications, some of which cannot be anticipated or predicted with any degree
of certainty. The Company recognizes that it must take action to ensure that
its operations will not be adversely impacted by Year 2000 software failures.
 
  The Company's State of Readiness. An initial systems survey of the GroupMAC
Companies was completed in March of 1998 and revealed that several of the
Company's core business applications possess Year 2000 problems. The Company
retained an outside consulting firm to more thoroughly evaluate the extent of
the problem and to assist the Company in preparing an action plan to address
the issues in a timely manner. The evaluation project began in early July of
this year.
 
  With the exception of the seven most recent acquisitions, the evaluation
project is substantially complete. The evaluation on the seven most recent
acquisitions is pending. The cost of bringing the evaluated systems into
compliance is estimated to be between $125,000 and $150,000, including all
software upgrade fees and implementation. These costs are independent of any
costs associated with the common information system discussed below. The
projected effort for the majority of the systems includes an upgrade to recent
vendor software releases that are fully Year 2000 compliant. Management is
working with the consultant to finalize implementation planning and to develop
tracking mechanisms to ensure upgrades are completed in a timely manner.
Additionally, the Company has engaged an outside consulting firm to evaluate
and estimate the impact of Year 2000 problems on potential future acquisitions
as part of the due diligence process.
 
  Independent of its Year 2000 activities discussed in the previous paragraph,
the Company continues to develop information systems throughout the
organization for its overall information needs that will be free of any Year
2000 limitations. While the Company is not dependent on the implementation of
the common information system to remedy its Year 2000 problem, priority for
implementation of the common information
 
                                      26
<PAGE>
 
systems will be given to those GroupMAC Companies where correction of the Year
2000 problem is an issue. The Company expects to commence user-acceptance
testing of the new information system before the second quarter of 1999 with
implementation to follow immediately thereafter.
 
  The Company is completing a plan to evaluate the effect of the Year 2000
problem on the Company's most significant customers and suppliers, and thus
indirectly on the Company. This evaluation is expected to be complete by
December 31, 1998. At this time, the Company has not assessed the potential
adverse effect on the Company with respect to customers and suppliers.
 
  Embedded Technology. The Company has focused its assessments to date on the
information technology systems. To date the Company's assessments indicate
that, due to the nature of the Company's operations, the non-information
technology systems (i.e. embedded technology such as microcontrollers) do not
represent a significant area of risk relative to Year 2000 readiness. The
Company's operations do not include capital intensive equipment with embedded
microcontrollers.
 
  Contingency Plan. The Company has not, to date, implemented a Year 2000
contingency plan. As explained above, the Company has initiated action to
identify and resolve Year 2000 problems. The Company will develop and
implement a contingency plan in the event the Company's present course of
action to solve the Year 2000 problem should fall behind schedule.
 
SEASONALITY AND CYCLICALITY
 
  The HVAC industry is subject to seasonal variations. Specifically, the
demand for new installations is generally lower during the winter months due
to reduced construction activities during inclement weather and less use of
air conditioning during the colder months. Demand for HVAC services is
generally higher in the second and third quarters. Accordingly, the Company
expects its revenues and operating results generally will be lower in the
first and fourth quarters. Historically, the construction industry has been
highly cyclical. As a result, the Company's volume of business may be
adversely affected by declines in new installation projects in various
geographic regions of the United States.
 
INFLATION
 
  Inflation did not have a significant effect on the results of operations of
the GroupMAC Companies for the years ended February 29, 1996 or February 28,
1997, the ten months ended December 31, 1997 or the six months ended June 30,
1998.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  During November and December 1997, the Company completed the IPO involving
the sale of 8.3 million shares of Common Stock at a price to the public of
$14.00 per share. The net proceeds from the IPO (after deducting underwriting
discounts and commissions and offering expenses) were approximately $103.6
million. Of this amount, $29.8 million was used to pay the cash portion of the
closing consideration relating to the acquisitions of one Pre-IPO Company and
the IPO Companies, $42.6 million to repay corporate indebtedness and debt
assumed in connection with the acquisition of the Founding Companies, $19.3
million to retire all of the then outstanding preferred stock and $11.9
million for general corporate purposes including working capital and final
consideration settlements related to the Founding Companies.
 
  Historically, the operations and growth of the Company have been financed
through internally generated working capital and borrowings from commercial
banks or other lenders. These borrowings were generally secured by
substantially all of the assets of the Company, as well as personal guarantees
of the respective owners.
 
  On June 12, 1998, the Company amended and restated its revolving credit
facility (the "Credit Agreement") to increase its borrowing capacity from
$75.0 million to $125.0 million. Under this Credit Agreement, the Company is
required to maintain (i) a minimum fixed charge coverage ratio; (ii) a maximum
ratio of total indebtedness for borrowed money to capitalization (as defined
in the Credit Agreement); (iii) a maximum ratio of debt to historical earnings
before interest, taxes, depreciation and amortization; (iv) a maximum amount
of other indebtedness in relation to consolidated shareholders' equity and (v)
a minimum amount of consolidated net worth. The Company is presently in
compliance with those covenants. The Credit Agreement matures on December 11,
2000.

  The Company's primary requirements for capital (other than those related to
acquisitions) consist of purchasing vehicles, inventory and supplies used in
the operation of the business. During the ten months ended December 31, 1997
and the six months ended June 30, 1998, capital expenditures aggregated $2.0
million and $4.6 million, respectively. The Company anticipates that its cash
flow from operations will provide cash in excess of the Company's normal
working capital needs, debt service requirements and planned capital
expenditures for property and equipment.
 
  For the years ended February 29, 1996 and February 28, 1997, the ten months
ended December 31, 1997 and the six months ended June 30, 1998, the Company
generated $4.0 million, $3.7 million, $4.4 million and $6.2 million in cash
from operating activities, respectively. For the year ended February 29, 1996,
net income, depreciation, amortization and deferred taxes generated $1.0
million, and changes in asset and liability accounts generated a net $3.0
million. For the year ended February 28, 1997, net income, depreciation,
amortization and deferred taxes generated $4.9 million, and changes in asset
and liability accounts utilized a net $1.2 million. For the ten months ended
December 31, 1997, net income, depreciation, amortization, deferred taxes and
non-cash compensation generated $7.5 million and changes in asset and
liability accounts utilized a net $3.1 million. For the six months ended June
30, 1998, net income, depreciation, amortization and deferred taxes generated
$12.8 million, and changes in asset and liability accounts utilized a net of
$6.6 million.
 
  The cash impact of investing activities for the years ended February 29,
1996 and February 28, 1997 was not significant. For the ten months ended
December 31, 1997, the Company used $37.9 million in investing activities. The
cash expended during the ten months ended December 31, 1997 consisted of $35.8
million for acquisitions and $2.0 million for capital expenditures. For the
six months ended June 30, 1998, the Company used $76.6 million in investing
activities. The cash expended during the six months ended June 30, 1998
consisted of $71.5 million for acquisitions and $4.4 million for net capital
expenditures and $0.7 million for deferred acquisition costs.
 
  The cash impact of financing activities for the years ended February 29,
1996 and February 28, 1997 was not significant. For the ten months ended
December 31, 1997, the Company generated $54.9 million in cash from its
financing activities. These activities principally consisted of issuance of
Common Stock for $109.7 million and proceeds from long-term debt of $32.5
million less distributions to shareholders of $20.4 million, payments of long-
term debt of $47.7 million and retirement of preferred stock of $19.3 million.
For the six months ended June 30, 1998, the Company generated $50.2 million in
cash from its financing activities. These activities principally consisted of
proceeds from the Credit Agreement of $74.4 million, less payments of long-
term debt of $24.2 million.
 
  During the fourth quarter of 1997, the Company registered seven million
shares of Common Stock under the Securities Act of 1933, as amended, for its
use in connection with future acquisitions. After their issuance, those
registered shares generally are freely tradable by persons not affiliated with
the Company unless the Company contractually restricts the resale.
Substantially all of the shares of Common Stock issued in connection with the
acquisition of the Founding Companies were not registered under the Securities
Act and were also subject to contractual restrictions on transfer. However,
the holders of these shares will be permitted to transfer a limited amount of
these shares during 1998.
 
  During the first half of 1998, the Company completed the acquisition of the
First and Second Quarter Post-IPO Companies, which were accounted for as
purchases, for approximately $157.8 million, which includes cash payments of
$85.5 million, $0.8 million of subordinated convertible debt, 5.4 million
shares of Common Stock and options to purchase 0.1 million shares of Common
Stock. Of the total consideration, approximately $5.4 million of cash and 0.1
million shares of Common Stock is due to former shareholders at June 30, 1998.
The Company financed the cash portion of the purchase price using (i)
remaining funds from the IPO, (ii) cash borrowed under the Credit Agreement
and (iii) internally generated funds. The combined 1997 annual revenues of
these companies were $292.1 million.
 
  From June 30, 1998 through August 31, 1998, the Company acquired eight
additional platform companies with combined annual revenues of 157.9 million.
Total consideration paid or to be paid was approximately $81.5 million
consisting of cash payments of $42.8 million, $4.0 million of notes payable,
2.4 million shares of Common
 
                                      28
<PAGE>
 
Stock and options to purchase 0.2 million shares of Common Stock. These
acquisitions will be accounted for as purchases. The Company financed the cash
portion of the purchase price with borrowings under the Credit Agreement. As
of August 18, 1998, the funds available under the Credit Agreement totaled
$17.7 million, subject to the maintenance of financial ratios and covenants.
 
  The Company intends to aggressively pursue acquisition opportunities.
Management believes that the Company has several viable financing alternatives
to meet the Company's anticipated requirements for acquisitions. Estimates as
to working capital needs and other expenditures may be materially affected if
the foregoing sources are not available or do not otherwise provide sufficient
funds to meet the Company's obligations.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information, which the Company is required to adopt for
annual periods beginning after December 15, 1997 and interim periods beginning
in fiscal year 1999. SFAS No. 131 establishes standards for the way that
public companies report information about operating segments in annual
financial statements and requires that those companies report information
about segments in interim financial reports issued to shareholders. The
Company has not yet completed its analysis of this statement and the impact on
its financial statements.

                                   BUSINESS
 
GENERAL
 
  The Company is one of the largest diversified providers of HVAC, plumbing
and electrical services to residential and commercial/industrial customers in
the United States.
 
  GroupMAC was incorporated in 1997 as the successor to a corporation which
developed a business plan to consolidate businesses engaged in the HVAC,
plumbing and electrical service industries. Prior to that time, the
predecessor company assembled a management team and support staff to implement
its business plan, obtained equity financing from a private investor, and
obtained a commitment from a bank to provide debt financing for its
acquisition program and for working capital.
 
  During 1997, the Company acquired the Founding Companies. At December 31,
1997, the Company had $329.0 million in pro forma 1997 revenues. Since that
date, the Company has acquired other businesses and currently operates 55
platform companies in 54 cities in 26 states.
 
  The Company intends to make additional acquisitions across the three main
technical disciplines (HVAC, plumbing and electrical) within the residential
and commercial markets. The Company's long-term objective is to develop
maintenance, repair and replacement capabilities (both residential and
commercial) in the top 100 markets within the United States, while offering
new installation services across a more limited range of markets where new
construction in the residential and/or commercial sectors is expected to out-
pace the national average over the long term. Over time, this objective is
expected to shift the revenues of the Company to an increased percentage of
service revenue.
 
  During November and December 1997, the Company completed the IPO involving
the sale of 8.3 million shares of its Common Stock at a price to the public of
$14.00 per share. The net proceeds from the IPO (after deducting underwriting
discounts and commissions and offering expenses) were approximately $103.6
million. Of this amount, $29.8 million was used to pay the cash portion of the
closing consideration relating to the acquisitions of several Founding
Companies, $42.6 million to repay corporate indebtedness and debt assumed in
connection with the acquisition of the Founding Companies, $19.3 million to
retire all of the then outstanding preferred stock and $11.9 million for
general corporate purposes including working capital, final consideration
settlements related to the Founding Companies and future acquisitions.
 
INDUSTRY OVERVIEW
 
  Based on available industry data, the Company believes the HVAC, plumbing
and electrical service industries in the United States represent a market with
annual revenues of approximately $100 billion. The HVAC service industry is
believed to generate approximately $65 billion in annual revenues, the
plumbing service industry generates approximately $19 billion in annual
revenues and the electrical service industry generates approximately $16
billion in annual revenues. The Company also believes these industries are
highly fragmented with over 100,000 businesses, consisting predominantly of
small, owner-operated companies focusing on a single local geographic area and
providing a limited range of services. The Company believes that the majority
of owners in its industry have limited access to adequate capital for
modernization, training and expansion and limited opportunities for liquidity
in their business. As a result of this fragmentation, several publicly traded
consolidators, in addition to the Company, have emerged in some or all of
these markets. The combined revenues of these consolidators and the Company
represent less than 3% of the revenues for the HVAC, plumbing and electrical
market.
 
  Growth in the HVAC service industry is affected by a number of factors,
particularly (i) the aging of the installed base of equipment, (ii) the
increasing efficiency, sophistication and complexity of HVAC systems and
 
                                      30
<PAGE>
 
(iii) the increasing restrictions on the use of refrigerants commonly used in
older HVAC systems. These factors also mitigate the effect on the HVAC service
industry of economic cycles inherent in the traditional construction industry.
An aging installed base has also positively affected growth in the plumbing
service industry. Industry sources report that 75% of the kitchen market and
65% of the bath market now consist of remodeling rather than new construction.
Growth in electrical services is closely tied to the new construction market,
although the retrofitting of existing structures is driven by increased demand
for computer networks and other modernization.
 
  The HVAC, plumbing and electrical service industries can be broadly divided
into the new installation market and the maintenance, repair and replacement
market. The new installation market includes the installation of HVAC,
plumbing and electrical systems in new homes and commercial buildings for
contractors, builders, developers and other users. The maintenance, repair and
replacement market includes the maintenance, repair and replacement and
reconfiguration of existing systems in residential homes and commercial
buildings. In the HVAC industry, the new installation market represents
approximately 34% of industry revenues, while the maintenance, repair and
replacement market represents 66% of industry revenues.
 
  The Company believes significant opportunities are available to a well
capitalized, national company employing professionally trained, customer-
oriented service technicians and providing a full complement of high quality
residential and commercial services in an industry that has been characterized
by inconsistent quality, reliability and pricing. In addition, the increasing
complexity of HVAC systems has led to a need for better trained technicians to
install, monitor and service these systems. The cost of recruiting, training
and retaining a sufficient number of qualified technicians makes it more
difficult for smaller HVAC companies to expand their businesses. The Company
also believes the highly fragmented nature of the residential and commercial
service industries will provide it with significant opportunities to
consolidate a large number of existing residential and commercial service
businesses.
 
SERVICES PROVIDED
 
  The Company provides a broad variety of maintenance, repair and replacement
services for HVAC, plumbing, electrical and other systems to both residential
and commercial customers. These services include preventive maintenance
(periodic checkups, cleaning and filter change-outs), emergency repairs, and
the replacement (in conjunction with the retrofitting or remodeling of a
residence or commercial building, or as a result of an emergency repair
request) of HVAC systems and associated parts, plumbing fixtures, pipes, water
feed and sewer lines, water heaters, softeners, filters and controls, and
electrical control systems, wiring, data cabling, switches and panels. The
Company also acts as a subcontractor for a variety of national, regional and
local residential home builders in the installation of HVAC, plumbing,
electrical and other systems in new residential construction, as well as
designing and installing HVAC, plumbing, electrical and other systems on
behalf of owners or general contractors in commercial buildings. In a few of
its operating locations, the Company provides certain specialized services,
including repair of home appliances, duct cleaning, installation and repair of
fireplaces, installation of fire sprinkler systems and the provision of
technical facilities management services to commercial building owners or
building managers. In connection with both its new installation business and
its maintenance, repair and replacement services, the Company sells a wide
range of HVAC, plumbing and electrical equipment, parts and supplies.

</TABLE>
 
FIELD OPERATIONS
 
  The Company's field operations are conducted out of the individual operating
locations of the various subsidiaries. Typically, the subsidiaries specialize
in one of the technical disciplines in either the residential or commercial
market. However, a few of the subsidiaries that operate principally in the
residential new installation or residential maintenance, repair and
replacement markets also engage to a limited extent in projects or service
work for "light commercial" customers (i.e., smaller commercial buildings
where systems are similar in design to residential systems). The Company
permits its subsidiaries to function in a largely autonomous manner in
delivering products and services to their respective markets. The Company
believes this flexible operating strategy improves each location's ability to
respond quickly to opportunities and competition.
 
 New Installation
 
  New installation service in the residential market begins with the home
builder providing architectural plans or mechanical drawings for the
particular type or types of residences within the tract to be developed, and
requesting a bid or contract proposal for the work (often broken into phases
within the tract). Company personnel analyze the plans and drawings and
estimate the equipment, materials and parts and the direct and supervisory
labor required for the project. The Company delivers a written bid or
negotiates the written agreement for the job. In HVAC installations, a portion
of the required air ducts are fabricated and pre-assembled with other
components in the Company's own facilities prior to delivery to the job site.
Other equipment and materials for the particular project are ordered from
manufacturers, distributors or other suppliers for delivery in time for the
scheduled onsite construction work. The installation work is coordinated by
the Company's field supervisors along with the builder's construction
supervisors. Draw payments for the project are generally obtained within 30
days of completing the installation, at which time any mechanics' and
materialmen's liens securing such payments are released. Interim payments are
often obtained to cover labor and materials costs on larger installation
projects.
 
  Commercial new installation work begins with a design request from the owner
or general contractor. Initial meetings with the parties allow the contractor
to prepare preliminary and then more detailed design specifications,
engineering drawings and cost estimates. Once a project is awarded, it is
conducted in pre-agreed phases and progress billings are rendered to the owner
for payment, less a retainage. Actual field work (ordering of equipment and
materials, fabrication or assembly of certain components, delivery of such
materials and components to the job site, scheduling of work crews with the
necessary skills, and inspection and quality
 
                                      32
<PAGE>
 
control) is coordinated in these same phases. The Company has established a
policy to review and approve any new installation project by an operating unit
that exceeds 5% of the projected annual revenue of that unit.
 
  Substantially all the equipment and component parts the Company sells or
installs are purchased from manufacturers and other outside suppliers. The
Company is not materially dependent on any of these outside sources.
 
 Maintenance, Repair and Replacement
 
  The operating units engaged in maintenance, repair and replacement services
use specialized systems to log service orders, schedule service calls,
identify and ready the necessary repair parts or equipment, track the work
order, provide information for communication with the service technicians and
customers, and prepare accurate invoices. Service histories and specific
product information are generally accessible to the dispatcher in a database
that may be searched by customer name or address. Maintenance, repair and
replacement service calls are initiated when a customer requests emergency
repair service or the Company calls the client to schedule periodic service
agreement maintenance. Service technicians are scheduled for the call or
routed to the customer's residence or business by the dispatcher via a
scheduling board or daily work sheet (for non-emergency service) or through
cellular telephone, pager or radio. Service personnel work out of the
Company's service vehicles, which carry an inventory of equipment, tools,
parts and supplies needed to complete the typical variety of jobs. The
technician assigned to a service call travels to the residence or business,
interviews the customer, diagnoses the problem, prepares and discusses a price
quotation, performs the work and often collects payment from the customer.
Service technicians may carry a Customer Assurance Pricing manual developed by
the Company which lists labor and equipment parts required to fulfill certain
tasks and the associated prices. This manual is custom generated for each
company from a database containing over 15,000 different repair operations and
which is updated for price changes periodically. This "flat rate pricing"
strategy allows the Company to monitor margins and labor productivity at the
point of sale, while increasing the level of customer satisfaction by
demonstrating greater fairness and objectivity in pricing. Payment for
maintenance, repair and replacement services not covered by a warranty or
service contract is generally requested in cash or by check or credit card at
the service location.
 
  A portion of the Company's service work is done to satisfy factory
warranties. For such services, the Company is generally compensated by the
manufacturer responsible for the defective equipment under warranty. The
Company attempts to enter into service contracts whereby the customer pays an
annual or semi-annual fee for periodic diagnostic services. The customers
under service contracts receive specific discounts from standard prices for
repair and replacement services.
 
CENTRALIZED SUPPORT SERVICES
 
  The Company provides certain management, financial, accounting and
logistical support services for its subsidiaries, including the following:
 
 Purchasing
 
  The Company has structured or believes it will be able to structure volume
purchasing arrangements or otherwise achieve purchasing economies of scale in
each of the following areas: (i) HVAC, plumbing and electrical equipment,
parts and supplies, (ii) purchase or lease and maintenance of service
vehicles, (iii) casualty and liability insurance, (iv) health insurance and
related benefits, (v) retirement benefits administration, (vi) office
equipment, (vii) marketing and advertising (including Yellow Pages), (viii)
long distance services and (ix) a variety of accounting, financial management,
marketing and legal services. The principal manufacturers of the products sold
by the Company include Carrier Air Conditioning, Inc., The Trane Company,
Lennox Industries, Inc., Goodman Manufacturing Corp., Amana, and International
Comfort Products.
 
                                      33
<PAGE>
 
 Management Information Systems
 
  With limited exceptions, the Company intends to continue to operate for the
near-term with the existing accounting and other computer systems currently in
place at the various operating units. The Company, however, requires each
operating unit to adopt a uniform chart of accounts and to standardize its
budgeting process and reports so that results among the operating units more
easily can be compared and integrated. In addition, where an operating unit
has a system in place that is inadequate for its existing or near-term needs,
the Company will begin the migration to a standard that will allow for greater
consistency (and a longer term change to a Company-wide, integrated system).
The Company has implemented regular financial and operational "flash reports"
and other mechanisms to allow for management control and oversight. The
Company will utilize this information to establish and monitor performance of
individual operating units against operating benchmarks and ratios.
 
 Employee Screening, Training and Development
 
  The Company is committed to providing the highest level of customer service
through the development of a highly trained workforce. Prior to employment,
the Company makes an assessment of the technical competence level of all
potential new employees, confirms background references and conducts criminal
and driving record checks. In addition, all employees of the Company are
subject to drug testing. Once hired, employees of the Company are required to
complete a progressive training program to advance their technical
competencies and to ensure that they understand and follow the Company's
safety practices and other internal policies. Both technical and customer
service personnel are given intensive training in customer communication,
sales and problem-solving skills.
 
  The Company also conducts a detailed internal evaluation of each operating
unit's strengths, weaknesses and compliance with recognized industry or
Company "best practices," and then designs a training program to develop and
enhance the communication, sales, management and other relevant skills of its
employees and management to bring about continuous improvement in these areas.
The Company acquired Callahan Roach and USA in part for their professional
training and consulting capabilities and intends to implement their market-
leading training programs throughout the Company.
 
  Callahan Roach provides Customer Assurance Pricing models to over 1,300 HVAC
and plumbing service companies across the United States. Callahan Roach has
been an industry leader in the development and commercialization of this flat
rate pricing best practice known as Customer Assurance Pricing. USA provides
training and other products and services to a network of approximately 80
independent service companies focused on maintenance, repair and replacement
of commercial HVAC systems.
 
  In order to ensure that best practices are shared among each of the
individual operating units, the Company has created a Council of Presidents
composed of the president or senior executive of each unit. The Council meets
on a regular basis, as well as dividing into smaller working committees, to
share operating practices and develop additional means to improve the overall
performance of the Company and the individual operating units. Best practices
that result from the work of the Council will be included in the training and
monitoring programs developed and disseminated throughout the Company and to
USA members.
 
 Advertising and Marketing
 
  The Company uses both general advertising and a direct sales force to market
its residential and commercial services (both new installation and repair
services) in its geographic markets. The Company continues to preserve and
enhance the value of the unique and long-standing trade names and customer
identification enjoyed by the individual operating units. The GroupMAC logo
and identifying marks will be featured on service trucks, marketing materials
and advertising of the operating units, but in a manner that does not detract
from the local brand. The Company is developing (initially for its
subsidiaries, but ultimately for delivery to the market through
 
                                      34
<PAGE>
 
licensed affiliates developed by Callahan Roach and USA) warranty and service
programs for the residential and commercial markets, as well as an aggressive
national account sales program focused on national and large regional home
builders, as well as major corporations, governmental and private
institutions, real estate investment trusts, real estate management firms and
other multi-location commercial property owners and managers.
 
COMPETITION
 
  The market for HVAC, plumbing and electrical services is highly competitive.
The Company believes that the principal competitive factors in the residential
and commercial services industry are (i) timeliness, reliability and quality
of services provided, (ii) range of services offered, (iii) market share and
visibility and (iv) price. The Company believes its strategy of creating a
leading national provider of comprehensive services directly addresses these
factors. The ability of the Company to employ, train and retain highly
motivated service technicians to provide quality services should be enhanced
by its ability to utilize professionally managed recruiting and training
programs. In addition, the Company expects to offer compensation, health and
savings benefits that are more comprehensive than most offered in the
industry, including stock options for substantially all employees. Competitive
pricing is possible through purchasing economies and other cost saving
opportunities that exist across each of the service lines offered and from
productivity improvements.
 
  Most of the Company's competitors are small, owner-operated companies that
typically operate in a single market. Certain of these smaller competitors may
have lower overhead cost structures and may be able to provide their services
at lower rates. Moreover, many homeowners have traditionally relied on
individual persons or small repair service firms with whom they have long-
established relationships for a variety of home repairs. There are currently a
limited number of public companies focused on providing residential or
commercial services in some of the same service lines provided by the Company.
 
  In addition, there are a number of national retail chains that sell a
variety of plumbing fixtures and equipment and HVAC equipment for residential
use and offer, either directly or through various subcontractors,
installation, warranty and repair services. Other companies or trade groups
engage in franchising their names and marketing programs in some service
lines. In the future, competition may be encountered from, among others, HVAC
equipment manufacturers, the unregulated business segments of regulated gas
and electric utilities or from newly deregulated utilities entering into
various residential or commercial service areas. Certain of the Company's
competitors and potential competitors have greater financial resources than
the Company to finance acquisition and development opportunities, to pay
higher prices for the same opportunities or to develop and support their own
residential or commercial service operations if they decide to enter the
field.
 
EMPLOYEES
 
  As of June 30, 1998, the Company had approximately 5,600 full and part-time
employees, of whom approximately 4,000 are installation/service technicians.
In the course of performing installation work, the Company may utilize the
services of subcontractors. Approximately 760 employees (in eight of the
commercial subsidiaries) are members of unions and work under collective
bargaining agreements. The collective bargaining agreements have expiration
dates between March 1999 and March 2003. The Company believes that its
relationship with its employees is generally satisfactory.
 
GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS
 
  Many aspects of the Company's operations are subject to various federal,
state and local laws and regulations, including, among others, (i) permitting
and licensing requirements applicable to service technicians in their
respective trades, (ii) building, HVAC, plumbing and electrical codes and
zoning ordinances, (iii) laws and regulations relating to consumer protection,
including laws and regulations governing service contracts for residential
services, and (iv) laws and regulations relating to worker safety and
protection of human health and
 
                                      35
<PAGE>
 
the environment. In Florida, warranties provided for in the Company's service
agreements subject the Company and such agreements to some aspects of that
state's insurance laws and regulations. Specifically, the Company is required
to maintain funds on deposit with the Florida Office of Insurance Commissioner
and Treasurer, the amount of which is not material to the Company's business.
The Company is in compliance with these deposit requirements.
 
  The Company believes it has all required permits and licenses to conduct its
operations and is in substantial compliance with applicable regulatory
requirements relating to its operations. Failure of the Company to comply with
the applicable regulations could result in substantial fines or revocation of
the Company's operating permits.
 
  A large number of state and local regulations governing the residential
services trades require various permits and licenses to be held by
individuals. In some cases, a required permit or license held by a single
individual may be sufficient to authorize specified activities for all the
Company's service technicians who work in the geographic area covered by the
permit or licenses.
 
  The Company's operations are subject to numerous federal, state and local
environmental laws and regulations, including those governing vehicle
emissions and the use and handling of refrigerants. These laws are
administered by the United States Environmental Protection Agency, the Coast
Guard, the Department of Transportation and various state and local
governmental agencies. The technical requirements of these laws and
regulations are becoming increasingly complex, stringent and expensive.
Federal and state environmental laws include statutes intended to allocate the
cost of remedying contamination among specifically identified parties. The
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"
or "Superfund") can impose strict, joint and several liability on past and
present owners or operators of facilities at, from, or to which a release of
hazardous substances has occurred, on parties who generated hazardous
substances that were released at such facilities and on parties who arranged
for the transportation of hazardous substances to such facilities. A majority
of states have adopted "Superfund" statutes comparable to, and in some cases
more stringent than, CERCLA. If the Company were to be found to be a
responsible party under CERCLA or a similar state statute, the Company could
be held liable for all investigative and remedial costs associated with
addressing such contamination, even though the releases were caused by a prior
owner or operator or third party. In addition, claims alleging personal injury
or property damage may be brought against the Company as a result of alleged
exposure to hazardous substances resulting from the Company's operations.
 
  Prior to entering into the agreements relating to the acquisition of
businesses, the Company evaluated the properties owned or leased by such
companies and in some cases engaged an independent environmental consulting
firm to conduct or review assessments of environmental conditions at certain
of those properties. No material environmental problems were discovered in
these reviews, and the Company is not otherwise aware of any actual or
potential environmental liabilities that would be material to the Company.
There can be no assurance that all such liabilities have been identified, that
such liabilities will not occur in the future, that a party could not assert a
material claim against the Company with respect to such liabilities, or that
the Company would be required or able to answer for such claim.
 
  The Company's operations are subject to federal, state and local laws and
regulations protecting the health and safety of workers. These laws are
administered by the federal Occupational Safety & Health Administration and
state and local health and safety governmental agencies. The Company's
operations are subject to the Clean Air Act, Title VI of which governs air
emissions and imposes specific requirements on the use and handling of
substances known or suspected to cause or contribute significantly to harmful
effects on the stratospherical ozone layer, such as chlorofluorocarbons and
certain other refrigerants ("CFCs"). Clean Air Act regulations require the
certification of service technicians involved in the service or repair of
systems, equipment and appliances containing these refrigerants and also
regulate the containment and recycling of these refrigerants. These
requirements have increased the Company's training expenses and expenditures
for containment and recycling equipment. The Clean Air Act is intended
ultimately to eliminate the use of CFCs in the United States and require
alternative refrigerants to be used in replacement HVAC systems. The
implementation of the Clean Air
 
                                      36
<PAGE>
 
Act restrictions has also increased the cost of CFCs in recent years and is
expected to continue to increase such costs in the future. As a result, the
number of conversions of existing HVAC systems that use CFCs to systems using
alternative refrigerants is expected to increase.
 
  The Company's operations in certain geographic regions are subject to laws
that will, over the next few years, require specified percentages of vehicles
in large vehicle fleets to use "alternative fuels," such as compressed natural
gas or propane, and meet reduced emissions standards. The Company does not
anticipate that the cost of fleet conversion that may be required under
current laws will be material. Future costs of compliance with these laws will
be dependent upon the number of vehicles purchased in the future for use in
the covered geographic regions, as well as the number and size of future
business acquisitions by the Company in these regions. The Company cannot
determine to what extent its future operations and earnings may be affected by
new regulations or changes in existing regulations relating to vehicle
emissions.
 
  Capital expenditures related to environmental matters during the six-month
period ended June 30, 1998 were not material. The Company does not currently
anticipate any material adverse effect on its business or consolidated
financial position as a result of future compliance with existing
environmental laws and regulations controlling the discharge of materials into
the environment. Future events, however, such as changes in existing laws and
regulations or their interpretation, more vigorous enforcement policies of
regulatory agencies or stricter or different interpretations of existing laws
and regulations may require additional expenditures by the Company which may
be material.

(1) Except as otherwise noted, all options were granted on the date of the
    Company's initial public offering (November 6, 1997), have a five year
    term and become exercisable with respect to 25% of the shares subject to
    the option on each anniversary of the date of grant.
(2) Options granted to Messrs. Norris and Luke at the time they commenced
    employment with the Company (on June 1, 1997 and August 1, 1997,
    respectively). These options have a ten-year term from the date of grant
    and become exercisable with respect to 33 1/3% of the shares subject to
    the option on each anniversary of the date of grant. Because the Company's

GROUP MAINTENANCE AMERICA CORP. COMPENSATION COMMITTEE REPORT ON EXECUTIVE
COMPENSATION
 
  The Compensation Committee (the "Committee") of the Board of Directors is
responsible for overseeing the development and implementation of the executive
compensation philosophy, plans and programs of the Company as described below.
The Committee is composed entirely of non-employee Directors.
 
 Compensation Philosophy
 
  The Company is a new publicly-traded company and has established a
philosophy for compensation of the Company executives and those of its
principal subsidiaries that is intended to appropriately align the interests
of the executives with those of the Company shareholders and be based on
awarding compensation in line with performance.
 
  In implementing this philosophy, the program has been structured to:
 
  . Provide as current compensation a base salary with a variable incentive
    award premised on achieving the Company's business objectives for the
    year, with primary emphasis on targeted earnings per share.
 
  . Develop and administer stock ownership programs for executives that
    provide strong incentives for long-term retention of senior executives.
 
  . Encourage stock ownership at all levels of the organization through stock
    option plans.
 
  . As the Company is a newly-formed company, the Committee will carefully
    review the effects in operation of the plans implemented to date to
    insure that the desired results are achieved, and will recommend to
    management any changes deemed desirable as a result of such review.
 
 Annual Cash Compensation Program
 
  BASE SALARIES
 
  As described elsewhere, each of the executive officers named in the Summary
Compensation Table entered into an employment agreement upon initial
employment with the Company providing for a specified base salary and an
annual cash bonus depending on the actual performance of the Company. Upon the
successful completion of the Company's initial public offering in November
1997 the Company paid a special cash bonus to each of its executives based
upon their respective salaries and length of time employed by the Company.
During 1998, further study of the salary structures of comparably-situated
companies will be made to determine what adjustment to salaries, if any, are
appropriate, consistent with the duties and responsibilities of each position.
 
  INCENTIVE BONUS PLANS
 
  The Board of Directors of the Company approved a cash incentive bonus plan
for its headquarters employees in 1998. Individual amounts payable under this
plan are dependent on (1) achieving a targeted earnings-per-share result; (2)
influence of the individual position on ability to achieve overall corporate
objectives; and (3) assessment of individual performance in carrying out the
assigned responsibilities.
 
  The Company has previously implemented a cash bonus program for the key
employees of its subsidiaries under which awards will be determined based upon
the performance of each subsidiary. The size of the bonus pool will be equal
to a defined percentage of the amount by which the subsidiary's after-tax net
operating profit (as defined) less a charge for capital allocated to the
subsidiary exceeds a similar calculation of the previous year's results. A
certain percentage of earned bonuses are carried over to the following year
for retention purposes and to promote long-term goal achievement. Messrs.
Jennings and Johnston participated in the program in 1997. Messrs. Bryant,
Henninger, Kelly and Sigmund will also participate in 1998.
 
                                      44

  LONG-TERM INCENTIVES--STOCK AWARDS PLANS
 
  The Company's long-term incentive plans (1997 Stock Awards Plan and 1997
Stock Option Plan) are intended to be a significant portion of the total
compensation package of the Company's senior executives and to provide an
ownership opportunity to employees at all levels of the organization. Pursuant
to this objective, awards were made at the time of the initial public offering
and will continue to be made periodically based on individual performance
evaluations and recommendations of the Chief Executive Officer and/or the
chief executive officer of each subsidiary corporation, as applicable.
 
  1997 CHIEF EXECUTIVE OFFICER COMPENSATION
 
  The base compensation of the Chief Executive Officer for 1997 continued at
the level of $150,000 as established in his initial employment agreement in
1996. While information provided by compensation consultants indicates that
this compensation is below base salaries of chief executive officers of
comparable companies, the Committee believes the Company's management group,
including the Chief Executive Officer, is properly incentivized by the overall
compensation program as described above.
 
  At the successful completion of the Company's initial public offering, the
Chief Executive Officer, as well as other senior officers of the Company,
received cash bonuses and awards under the 1997 Stock Awards Plan. Mr.
Millinor received an $87,500 cash bonus and an option to purchase 56,500
shares of stock. These options are exercisable at $14.00 per share over a
period of five years with 25% of such shares becoming exercisable at each
anniversary of the date of grant.
 
  The Chief Executive Officer's contribution for the period is most clearly
evidenced by the successful completion of the Company's initial public
offering several months ahead of schedule. Mr. Millinor demonstrated
outstanding leadership in directing the Company during the period leading to
the initial public offering in November 1997. Implementation of the Company's
business plan required identifying and employing additional members of the
management team needed to successfully manage and coordinate the acquisition
program and working closely with the group in identifying and negotiating the
terms of the acquisitions. In addition, he led the effort required to develop
a plan to effectively coordinate the ongoing operations of the acquired
companies after the initial public offering.

PERFORMANCE GRAPH
 
  The following graph compares the percentage change in the market value of
the Company's Common Stock to the cumulative total stockholder return (change
in stock price plus reinvested dividends) of the Standard & Poor's 500 Stock
Index ("S&P 500 Index") and a group of three peer issuers (the "Peer Group
Index") for the portion of 1997 that the Company's Common Stock was registered
pursuant to Section 12 of the Exchange Act, assuming the investment of $100 on
November 7, 1997, the date immediately following the date of the IPO, and the
reinvestment of all dividends since that date to December 31, 1997. The three
peer issuers are American Residential Services, Inc., Comfort Systems USA,
Inc. and Service Experts, Inc., each of which is a publicly traded company
engaged (either directly or through subsidiaries) in the same or similar
business as the Company. The Peer Group Index was weighted for market
capitalization.

                          RELATED PARTY TRANSACTIONS
 
  Airtron leases its headquarters offices in Dayton, Ohio and its operating
facilities in Cincinnati and Cleveland, Ohio, Indianapolis, Indiana,
Clearwater, Florida, Dallas, Houston and San Antonio, Texas and Wichita,
Kansas from entities controlled by certain former shareholders of Airtron,
including Messrs. Jennings and Johnston. None of these leases expire prior to
2008. The aggregate annual base rent to be paid under these leases is
approximately $735,000 with annual increases based on the consumer price
index. The Company believes that the terms of such leases are no less
favorable to the Company than could have been negotiated by the Company with
unaffiliated third parties.
 
  In the Company's acquisition of Airtron, Mr. Jennings received $3,729,653,
together with 933,908 shares of Common Stock and 2,711,344 shares of Series A
Preferred Stock, and Mr. Johnston received $1,393,474, together with 374,713
shares of Common Stock and 1,057,473 shares of Series A Preferred Stock. All
of such shares of preferred stock were redeemed at a redemption price of $1.00
per share. Additionally, Messrs. Jennings and Johnston have the right to
receive payments from the Company equal to the tax benefits received by the
Company with respect to payments of deferred compensation to them. The Company
estimates these payments will be $3.2 million and $1.4 million, respectively.
 
  In the Company's acquisition of K&N, Andrew Jeffrey Kelly received
$1,568,000, together with 362,800 shares of Common Stock and 1,568,000 shares
of Series D Preferred Stock. All of such shares of preferred stock were
redeemed at a redemption price of $1.00 per share. Mr. Kelly may receive
contingent consideration based on the operating results of K&N for the 15
month period ended June 30, 1998. The Company estimates that such payments
will be approximately $600,000. K&N entered into a new five year renewable
lease with Sigma Management, a company owned by Mr. Kelly, to replace the
existing lease for the Company's Arlington, Texas facility. The annual base
rent to be paid under this lease is approximately $94,800. The Company
believes that the terms of such lease are no less favorable to the Company
than could have been negotiated by the Company with unaffiliated third
parties.
 
  In the Company's acquisition of MacDonald-Miller, Fredric J. Sigmund
received approximately $1,937,000 and 207,588 shares of Common Stock.
MacDonald-Miller has entered into a new ten year renewable lease with F&V
Investments, a company owned by Mr. Sigmund, to replace the existing lease for
MacDonald-Miller's Seattle, Washington facility. The annual base rent to be
paid under this lease is approximately $475,000. The Company believes that the
terms of such lease are no less favorable to the Company than could have been
negotiated by the Company with unaffiliated third parties.
 
  In the Company's acquisition of Masters, Ronald D. Bryant received
approximately $5,325,000 and 466,806 shares of Common Stock. Additionally,
Masters entered into a new six year renewable lease with Mr. Bryant to replace
the existing lease for Masters' Gaithersburg, Maryland facility. The annual
base rent to be paid under this lease is approximately $242,000, with annual
increases of 4%. The Company believes that the terms of such lease are no less
favorable to the Company than could have been negotiated by the Company with
unaffiliated third parties.
 
  In the Company's acquisition of Van's, David L. Henninger received, together
with his spouse, approximately $1,497,000 and 112,200 shares of Common Stock.
Additionally, Van's entered into a new five-year renewable lease with Mr.
Henninger to replace the existing lease for Van's Delray Beach, Florida
facility. The initial annual base rent to be paid under this lease is
approximately $90,000 with annual increases of 3%. The Company believes that
the terms of such lease are no less favorable to the Company than could have
been negotiated by the Company with unaffiliated third parties. Finally, Mr.
Henninger owed approximately $80,000 to Van's at the time it was acquired by
the Company. This indebtedness was satisfied in December 1997 by an offset to
a purchase price adjustment owed by the Company to Mr. Henninger.
 
  In 1997, Mr. Sullivan, a director of the Company, exercised options to
purchase 10,000 shares at a price of $3.08 per share.

                         DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
  Under the Company's Articles of Incorporation, as amended (the "Articles"),
the Company has authority to issue 150,000,000 shares of capital stock,
consisting of 50,000,000 shares of Preferred Stock, par value $0.001 per share
(the "Preferred Stock"), and 100,000,000 shares of Common Stock, par value
$0.001 per share. As of August 31, 1998, the Company had outstanding
27,975,585 shares of Common Stock and no shares of Preferred Stock.
 
  The following summary description of the material features of the capital
stock of the Company is intended as a summary only and is qualified in its
entirety by reference to the Articles, a copy of which has been filed as an
exhibit to the Registration Statement of which this Prospectus is a part.
 
PREFERRED STOCK
 
  The Articles authorize the issuance of Preferred Stock in one or more series
having designations, rights and preferences determined from time to time by
the Board of Directors. Accordingly, the Board of Directors is empowered,
without approval of holders of Common Stock, to issue Preferred Stock with
dividends, liquidation, conversion, voting or other rights that could
adversely affect the voting power or other rights of the holders of the Common
Stock. In the event of issuance, the Preferred Stock could be used, under
certain circumstances, as a method of discouraging, delaying or preventing a
change in control of the Company. Although the Company has no present
intention to issue any additional shares of its Preferred Stock, there can be
no assurance that it will not do so in the future.
 
COMMON STOCK
 
  Voting Rights. Holders of Common Stock are entitled to one vote for each
share on all matters on which shareholders generally are entitled to vote,
including elections of directors. The Board of Directors is classified into
three classes of five directors, with the term of each class expiring on a
staggered basis. The classification of the Board of Directors may make it more
difficult to change the composition of the Board of Directors and thereby may
discourage or make more difficult an attempt by a person or group to obtain
control of the Company. The Articles do not provide for cumulative voting for
the election of directors.
 
  Dividends. Subject to the preferential rights of any outstanding Preferred
Stock that may be created by the Board of Directors under the Articles,
dividends may be paid to holders of Common Stock when, as and if declared by
the Board of Directors out of funds legally available for such purpose. The
declaration and payment of dividends on Common Stock could be restricted by
the terms of any Preferred Stock issued. Under the TBCA, dividends may be paid
by the Company out of "surplus" (as defined under Article 1.02 of the TBCA)
or, if
 
                                      51
<PAGE>
 
there is no surplus, out of net profits for the fiscal year in which the
dividends are declared and/or the preceding fiscal year. However, the Company
does not intend to pay dividends at the present time. See "Dividend Policy"
and "Description of Bank Credit Agreement."
 
  Liquidation. In the event of the dissolution or winding up of the Company,
after payment or provision for payment of debts and other liabilities of the
Company and any other series or class of the Company's stock hereafter issued
that ranks senior as to liquidation rights to the Common Stock, the holders of
Common Stock will be entitled to receive pro rata all remaining assets of the
Company available to such holders.
 
  Miscellaneous. Holders of Common Stock have no preemptive, subscription,
redemption or conversion rights.
 
  The Common Stock is listed on the New York Stock Exchange under the symbol
"MAK."
 
  The transfer agent and registrar for the Common Stock is ChaseMellon
Shareholder Services, L.L.C.
 
STATUTORY BUSINESS COMBINATION PROVISION
 
  The Company is subject to Article 13 of the TBCA ("Article 13") which, with
certain exceptions, prohibits a Texas corporation from engaging in a "business
combination" (as defined in Article 13) with any shareholder who is a
beneficial owner of 20% or more of the corporation's outstanding stock for a
period of three years after such shareholder's acquisition of a 20% ownership,
unless: (i) the board of directors of the corporation approves the transaction
or the shareholder's acquisition of shares prior to the acquisition or (ii)
two-thirds of the unaffiliated shareholders of the corporation approve the
transaction at a shareholders' meeting. Shares that are issuable, but have not
yet been issued, pursuant to options, conversion or exchange rights or other
agreements are not considered outstanding for purposes of Article 13.
 
CERTAIN PROVISIONS OF THE ARTICLES OF INCORPORATION AND BYLAWS
 
  The Articles contain a "fair price" provision which generally requires that
certain mergers, business combinations and similar transactions constituting a
"Business Combination" with an "Interested Shareholder" (generally the
beneficial owner of at least 10 percent of the Company's voting stock) be
approved by the holders of a least 80 percent of the Company's voting stock,
unless (i) the transaction is approved by at least 80 percent of the
"Continuing Directors" of the Company, who constitute a majority of the entire
board or (ii) certain "fair price" and procedural requirements are satisfied.
The Articles define "Business Combination" as (i) any merger or consolidation
involving the Company or a subsidiary of the Company, (ii) any sale, lease,
exchange, transfer or other disposition (in one transaction or a series of
transactions), including without limitation a mortgage or any other security
device, of all or any substantial part of the assets either of the Company or
of a subsidiary of the Company to or with any Interested Shareholder, (iii)
the issuance, sale, exchange, transfer or other disposition by the Company or
a subsidiary of the Company of any securities of the Company or any subsidiary
of the Company to or with any Interested Shareholder, (iv) any
recapitalization or reclassification of the Company's securities (including
without limitation, any reverse stock split) or other transaction that would
have the effect of increasing the voting power of an Interested Shareholder,
(v) any liquidation, spinoff, splitoff, splitup or dissolution of the Company
proposed by or on behalf of any Interested Shareholder, and (vi) any
agreement, contract or other arrangement providing for any of the transactions
described in this definition of Business Combination. "Continuing Director" is
defined to mean a director who either was a member of the Board of Directors
of the Company prior to the time such Interested Shareholder became an
Interested Shareholder or who subsequently became a director of the Company
and whose election, or nomination for election by the Company's shareholders,
was approved by a vote of at least 80 percent of the Continuing Directors then
on the Board of Directors, either by a specific vote or by approval of the
proxy statement issued by the Company on behalf of the Board of Directors in
which such person is named as nominee for director, without an objection to
such nomination; provided, however, that in no event shall a director be
considered a "Continuing Director" if
 
                                      52
<PAGE>
 
such director is an Interested Shareholder and the Business Combination to be
voted upon is with such Interested Shareholder or is one in which such
Interested Shareholder otherwise has an interest (except proportionately as a
shareholder of the Company).
 
  In accordance with the Company's Bylaws, a shareholder of the Company may
nominate persons for election to the Board of the Company if the shareholder
submits such nomination, together with certain related information required by
the Company's Bylaws, in writing to the Secretary of the Company not less than
50 days nor more than 75 days prior to the date of any annual meeting of
shareholders.
 
                        DESCRIPTION OF CREDIT AGREEMENT
 
GENERAL
 
  The lenders under the Company's Credit Agreement are committed to provide
the Company, subject to certain terms and conditions, the entire $125 million
principal amount of the revolving credit facility described below. The
following description summarizes the material provisions of the Credit
Agreement. The following description does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, the provisions
of the Credit Agreement, filed as an exhibit to the registration statement
relating to this Prospectus.
 
AMORTIZATION; PREPAYMENTS
 
  Loans under the Credit Agreement may be prepaid at any time without premium
or penalty in reasonable minimum amounts. Prepayments of Eurodollar borrowings
on any day other than the last day of an interest period must be accompanied
by a payment to the Lenders of various costs, expenses or losses, if any,
incurred as a result of such prepayment. Any loans under the Credit Agreement
are payable in full on December 9, 2000.
 
SECURITY; GUARANTEES
 
  Borrowings under the Credit Agreement are guaranteed by the Company's
Material Subsidiaries (as defined in the Credit Agreement), including future
Material Subsidiaries. The obligations of the Company under the Credit
Agreement and the obligations under the guarantees are secured by a first
priority lien on the accounts receivable and inventory of certain Material
Subsidiaries, and by a pledge of stock of its domestic subsidiaries.
 
INTEREST RATES
 
  Loans under the Credit Agreement bear interest at a rate per annum, at the
Company's option, of either (i) the Alternate Base Rate which is equal to the
greater of the Federal Funds Effective Rate (as defined in the Credit
Agreement) plus 0.5% or the Prime Rate (as defined in the Credit Agreement)
plus a margin depending on the ratio of indebtedness for borrowed money to
Adjusted EBITDA (as defined in the Credit Agreement), or (ii) the Eurodollar
Rate (as defined in the Credit Agreement) plus a margin depending on the ratio
of indebtedness for borrowed money to Adjusted EBITDA.
 
FEES, EXPENSES AND COSTS; CREDIT FACILITIES
 
  The terms of the Credit Agreement require the Company to pay the following
fees in connection with the maintenance of loans under the Credit Agreement:
(i) commitment fees to be paid to the Lenders in amounts between 0.25% and
0.375% per annum with respect to the unused commitments under the Credit
Agreement depending on the ratio of indebtedness for borrowed money to
Adjusted EBITDA, payable quarterly in arrears until such time as such facility
is terminated; and (ii) administration fees payable annually to the Agent. In
addition, the Company paid various underwriting and arrangement fees and
closing costs in connection with the origination and syndication of the Credit
Agreement.
 
                                      53
<PAGE>
 
  The Company is required to reimburse the Agent for all reasonable out-of-
pocket costs and expenses incurred in the preparation, documentation and
administration of the Credit Agreement and to reimburse the Lenders for all
reasonable costs and expenses incurred in connection with the enforcement of
their rights in connection with a default or the enforcement of the Credit
Agreement. The Company must indemnify the Agent and the Lenders and their
respective officers, directors, shareholders, employees, agents and attorneys
against certain costs, expenses (including fees and reimbursements of counsel)
and liabilities arising out of or relating to the Credit Agreement and the
transactions contemplated thereby. The Lenders also are entitled to be
reimbursed for certain reserve requirements and increases therein, changes in
law and circumstances, taxes (other than on overall net income), capital
adequacy, and consequential costs. Further, the inability to determine
Eurodollar Rates or the possible future illegality of the Eurodollar Rate
option will result in such rate option being unavailable.
 
COVENANTS
 
  The Credit Agreement contains substantial restrictive covenants limiting the
ability of the Company and its subsidiaries to: (i) incur Indebtedness (as
defined in the Credit Agreement), including contractual contingent
obligations; (ii) pay certain debt after default; (iii) create or allow to
exist liens or other encumbrances; (iv) transfer assets except for sales and
other transfers of inventory or surplus, immaterial or obsolete assets in the
ordinary course of business; (v) enter into mergers, consolidations and asset
dispositions of all or substantially all of its properties; (vi) make
investments; (vii) extend credit to any entity; (viii) sell, transfer or
otherwise dispose of any class of stock or the voting rights of any subsidiary
of the Company; (ix) enter into transactions with related parties other than
on an arm's-length basis on terms no less favorable to the Company than those
available from third parties; (x) amend certain agreements; (xi) make any
material change in the nature of the business conducted by the Company; (xii)
pay dividends or redeem shares of capital stock; and (xiii) make capital
expenditures.
 
  In addition, the Credit Agreement contains covenants that, among other
things and with certain exceptions, require the Company and its subsidiaries
to: (i) maintain the existence, qualification and good standing of the Company
and its subsidiaries; (ii) comply in all material respects with all material
applicable laws; (iii) maintain material properties, rights and franchises;
(iv) deliver certain financial and other information; (v) maintain specified
insurance; (vi) pay taxes; and (vii) notify the Lenders of any default under
the Loan Documents (as defined in the Credit Agreement) and of certain other
material events.
 
  Under the Credit Agreement, the Company is required to satisfy certain
financial covenants and tests, including (i) a minimum fixed charge coverage
ratio; (ii) a maximum ratio of total indebtedness for borrowed money to
Capitalization (as defined in the Credit Agreement); and (iii) a minimum
Consolidated Net Worth (as defined in the Credit Agreement).
 
EVENTS OF DEFAULT
 
  Events of Default under the Credit Agreement include, subject to certain
applicable notice and grace periods, the following: (i) a default in the
payment when due of any principal, interest, fees or other amount under the
Credit Agreement; (ii) a default by the Company under any debt instrument in
excess of $500,000, or the occurrence of any event or condition that enables
the holder of such debt to accelerate the maturity thereof; (iii) any material
breach of any representation, warranty or statement in, or failure to perform
any duty or covenant under the Credit Agreement or any of the Loan Documents;
(iv) commencement of voluntary or involuntary bankruptcy, insolvency or
similar proceedings by or against the Company or any Material Subsidiary; (v)
any judgment or order in excess of $500,000 net of confirmed insurance
remaining undischarged or unstayed for longer than certain periods; and (vi) a
Change of Control (as defined in the Credit Agreement).

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  As of August 31, 1998, the Company had outstanding 27,975,585 shares of
Common Stock. Of these shares, the 8,340,000 shares sold in the IPO are freely
tradeable in the public market without restriction or limitation under the
Securities Act, except for any shares held by an "affiliate" (as defined in
the Securities Act) of the Company. Approximately 9.5 million shares of Common
Stock held by existing shareholders of the Company immediately prior to the
IPO and the 3.3 million shares of Common Stock which were issued in connection
with the acquisition of the Offering Acquisition Companies, Costner, Way
Residential and Callahan Roach, are "restricted securities" within the meaning
of Rule 144, except for the approximately 725,000 shares of Common Stock
registered under the Securities Act in connection with the acquisition of
MacDonald-Miller. Approximately 6.9 million of the shares issued or to be
issued in connection with the acquisition of the Post-IPO Companies are
registered and freely tradeable under the Securities Act, but are subject to
contractual restrictions on resale during the two years from the date of
issuance. In addition, pursuant to the provisions of Rule 145 under the
Securities Act, the volume limitations and certain other requirements of Rule
144 under the Securities Act will apply to resales of those shares issued by
the Company to affiliates of any of the Post-Offering Companies for a period
of one year from the date of issuance.
 
  In general, under Rule 144, as currently in effect, a person (or persons
whose shares are required to be aggregated) who has beneficially owned, for at
least one year, shares of Common Stock that have not been registered under the
Securities Act or that were acquired from an "affiliate" of the Company is
entitled to sell within any three-month period the number of shares of Common
Stock that does not exceed the greater of (i) one percent of the number of the
then outstanding shares or (ii) the average weekly reported trading volume of
the Common Stock during the four calendar weeks preceding the sale. Sales
under Rule 144 are also subject to certain notice requirements and to the
availability of current public information about the Company and must be made
in unsolicited brokers' transactions or to a market maker. A person (or
persons whose shares are aggregated) who is not an "affiliate" of the Company
under the Securities Act during the three months preceding a sale and who has
beneficially owned such shares for at least two years is entitled to sell such
shares under Rule 144(k) without regard to the information, volume, manner of
sale and notice provisions of such Rule. At the date of this Prospectus,
approximately 9.5 million "restricted" shares of Common Stock are eligible for
resale pursuant to Rule 144, subject to the volume, manner of sale and other
limitations thereof and the remaining "restricted" shares will become eligible
for resale pursuant to Rule 144 from time to time thereafter.
 
  On the date of this Prospectus, the Company had outstanding options and
warrants to purchase approximately 3.7 million shares of Common Stock,
approximately 1.5 million of which are exercisable within 60 days of the date
of this Prospectus. The Company has filed a registration statement on Form S-8
under the Securities Act to register the shares of Common Stock issuable upon
the exercise of options granted by the Company. Accordingly, such shares will
be freely tradeable by holders who are not affiliates of the Company and,
subject to the volume and manner of sale limitations of Rule 144, by holders
who are affiliates of the Company.
 
  No predictions can be made of the effect, if any, that market sales of
shares of Common Stock or the availability of such shares for sale will have
on the market price prevailing from time to time. Nevertheless, sales of
significant amounts of Common Stock could adversely affect the prevailing
market price of Common Stock, as well as impair the ability of the Company to
raise capital through the issuance of additional equity securities.
 
TRANSFER RESTRICTIONS
 
  Purchasers of Common Stock in the acquisitions of the Founding Companies and
certain Post-Offering Companies entered into substantially similar Stock
Transfer Restrictions Agreements, which generally require that, at any time
that the Company is engaged in an underwritten public offering of its
securities, each shareholder who is a party thereto shall refrain from making
any disposition of Common Stock on a securities exchange, in the over-the-
counter or any other public trading market for the period of time requested by
the Company;
 
                                      55
<PAGE>
 
provided, however, that (i) the restrictions on the transfer of Common Stock
shall not limit any shareholder's right to sell Common Stock pursuant to any
piggyback registration right that such shareholder may have pursuant to any
registration rights or similar agreement binding upon the Company and (ii)
such restrictions are no more restrictive than those imposed on the management
of the Company. Additionally, each Stock Transfer Restriction Agreement
provides that, during the one-year period following the date of such agreement
(the "First Holding Period"), the shareholder will not dispose of his or her
shares of Common Stock (subject to certain limited exceptions generally
involving transfers to family members and trusts or pursuant to an effective
registration statement). In addition to the foregoing restrictions, during the
one year period following the First Holding Period (the "Second Holding
Period"), no shareholder who is a party thereto may dispose of any Common
Stock in any calendar month in an amount greater than 3% of the number of
shares of Common Stock issued to such shareholder increasing cumulatively for
months in which less than 3% was sold. After expiration of the Second Holding
Period, all such restrictions under the Stock Transfer Restriction Agreements
lapse. Finally, any shareholder who is a party thereto shall provide five
business days' notice to the Company prior to any proposed disposition until
the later of (i) the end of the one-year period following the Second Holding
Period, (ii) for as long as such shareholder is an officer or director of the
Company or any of its subsidiaries and (iii) the date on which such
shareholder ceases to hold the greater of 20,000 shares of Common Stock or 20%
of the number of shares originally held.
 
  No shareholder who is a party thereto shall make a transfer of any Common
Stock if such action would constitute (i) a violation of any federal or state
securities law, (ii) a breach of any condition to any exemption from
registration of the Common Stock under any such laws or (iii) a breach of any
undertaking or agreement of such shareholder entered into pursuant to such
laws or in connection with obtaining an exemption thereunder.
 
  The summary herein of certain provisions of the Stock Transfer Restriction
Agreements does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all of the provisions thereof, the form of
which is filed as an exhibit to the Registration Statement.
 
REGISTRATION RIGHTS
 
  Pursuant to several Registration Rights Agreements, as amended (the
"Registration Rights Agreements"), the Company has agreed to register under
the Securities Act up to approximately 12.5 million shares of Common Stock.
Pursuant to the Registration Rights Agreements, the shareholders who are
parties thereto will be entitled, subject to certain limitations, to include
their shares of Common Stock in a registration of shares of Common Stock
subsequent to the IPO which is initiated by the Company under the Securities
Act. The Registration Rights Agreement with respect to the founding
shareholders of the Company additionally provides that any one or more
shareholders holding a minimum number of shares of Common Stock has the right
to require the Company to effect a registration of all or any part of the
shares of Common Stock under the Securities Act (a "Demand Registration"). In
the event the aggregate number of shares of Common Stock which the
shareholders request the Company to include in any registration, together, in
the case of a registration initiated by the Company, with the shares of Common
Stock of the Company to be included in such registration, exceeds the number
that in the opinion of the managing underwriter can be sold in such offering
without materially affecting the offering price of such shares, the number of
shares of each shareholder to be included in such registration will be reduced
pro rata based on the aggregate number of shares for which registration was
requested.
 
  The Company at its option may delay the filing of a registration statement
required pursuant to any Demand Registration for up to 120 days if it has
determined that filing a registration statement would be seriously detrimental
to the Company or its shareholders or that a delay in filing the registration
statement is necessary in light of a pending corporate development. In
addition, although the Company's founding shareholders have the right to have
the shares of Common Stock owned by them registered by the Company under the
Securities Act, each of them has agreed not to exercise their respective
demand rights for the two year period following the IPO except for Mr. Cain
who has agreed to not exercise his demand rights for one year.
 
  The Registration Rights Agreements contain customary provisions whereby the
Company and the shareholders party thereto agree to indemnify and contribute
to the other with regard to losses caused by the
 
                                      56
<PAGE>
 
misstatement of any information or the omission of any information required to
be provided in a registration statement filed under the Securities Act. The
Registration Rights Agreements require the Company to pay the expenses
associated with any registration other than sales discounts, commissions,
transfer taxes and amounts to be borne by underwriters or as otherwise
required by law.
 
  The summary herein of certain provisions of the Registration Rights
Agreements does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all of the provisions of the forms of
Registration Rights Agreements, copies of which are filed as exhibits to the
registration statement relating to this Prospectus.
 
                             PLAN OF DISTRIBUTION
 
  This Prospectus covers the offer and sale of up to 7,000,000 shares of
Common Stock, which the Company may issue from time to time in connection with
future direct and indirect acquisitions of other businesses, properties or
securities in business combination transactions.
 
  The Company expects that the (i) terms on which it may issue the shares of
Common Stock covered hereby will be determined by direct negotiations with the
owners or controlling persons of the businesses or assets to be acquired and
(ii) the shares of Common Stock issued will be valued at prices reasonably
related to market prices prevailing either at the time an acquisition
agreement is executed or at or about the time of delivery of shares.

                         UNAUDITED PRO FORMA COMBINED
                             FINANCIAL STATEMENTS
 
  Although for legal purposes Airtron, Inc. ("Airtron") was acquired by Group
Maintenance America Corp. ("GroupMAC"), for accounting purposes, the
transaction was accounted for as a reverse acquisition, as if Airtron acquired
GroupMAC, due to the fact that the former shareholders of Airtron then owned a
majority of the GroupMAC common stock. The following unaudited pro forma
combined financial statements give effect to the acquisition of Airtron and
(i) 10 companies acquired prior to the IPO (together with Airtron, the "Pre-
IPO Companies"), (ii) 13 companies acquired in connection with the IPO (the
"IPO Companies") and (iii) 15 companies in the first quarter of 1998 (the
"First Quarter Post-IPO Companies"), 12 companies in the second quarter of
1998 (the "Second Quarter Post-IPO Companies") and eight companies in the
third quarter of 1998 (the "Third Quarter Post-IPO Companies", and together
with the First Quarter Post-IPO Companies and the Second Quarter Post-IPO
Companies, the "Post-IPO Companies", and together with the Pre-IPO Companies
and the IPO Companies, the "GroupMAC Companies"). The Post-IPO Companies are
as follows:

  All of the acquisitions were or will be accounted for under the purchase
method of accounting. These unaudited pro forma combined financial statements
are based on the historical financial statements of the acquired companies and
estimates and assumptions set forth below and in the notes to the unaudited
pro forma combined financial statements.
 
  The unaudited pro forma combined balance sheet combines the historical
consolidated balance sheet of the Company and the balance sheets of the Third
Quarter Post-IPO Companies, as if such acquisitions had occurred on June 30,
1998. The accompanying unaudited pro forma statements of operations of the
Company combines the historical statements of operations of the Company and
the statements of operations of the acquired entities as if such acquisitions
had occurred on January 1, 1997.
 
  GroupMAC has analyzed the savings that it expects to realize from reductions
in salaries and certain benefits to the owners. To the extent the owners of
the GroupMAC Companies have agreed prospectively to reductions in salary,
bonuses and benefits, these reductions have been reflected in the unaudited
pro forma combined statements of operations. With respect to other potential
cost savings, GroupMAC cannot fully quantify these savings at this time. It is
anticipated that these savings will be partially offset by costs related to
GroupMAC's corporate management and by the costs associated with being a
public company. However, because these savings and costs cannot be accurately
quantified at this time, they have not been included in the pro forma combined
financial information of GroupMAC.
 
  The pro forma adjustments are based on available information and certain
assumptions that management deems appropriate and may be revised as additional
information becomes available. Certain acquisitions are subject to final
equity adjustments, of which an estimate is reflected in the pro forma
adjustments. The pro forma combined financial data do not purport to represent
what GroupMAC's financial position or results of operations would actually
have been if such transactions had in fact occurred on those dates and are not
necessarily representative of GroupMAC's financial position or results of
operations for any future period. Since the acquisitions have not historically
been under common control or management, historical pro forma combined results
may not be indicative of or comparable to future performance. The unaudited
pro forma combined financial statements should be read in conjunction with
other financial statements and notes thereto included elsewhere in this
Prospectus. See "Risk Factors" included elsewhere herein.

          NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
1. BACKGROUND:
 
  The respective results of operations for the Pre-IPO and IPO Companies from
January 1, 1997 to the dates of the acquisitions were combined with the
Company and the Post-IPO Companies, excluding Premex, Inc. ("Commercial Air"),
actual results of operations for the twelve months ended December 31, 1997 and
Commercial Air for the twelve months ended March 31, 1998 to determine the pro
forma results of operations for the twelve months ended December 31, 1997.
 
   The respective results of operations for the Pre-IPO Companies, IPO
Companies and the Post-IPO Companies from January 1, 1997 to the dates of the
acquisitions, or June 30, 1997 for acquisitions consummated subsequent to June
30, 1997, were combined with actual results of the Company for the six months
ended June 30, 1997 to determine the pro forma results of operations for the
six months ended June 30, 1997. The respective results of operations for the
Post-IPO Companies from January 1, 1998 to the dates of the acquisitions, or
June 30, 1998 for acquisitions consummated subsequent to June 30, 1998, were
combined with actual results of the Company for the six months ended June 30,
1998 to determine the pro forma results of operations for the six months ended
June 30, 1998.
 
2. ACQUISITIONS:
 
  The acquisitions of the Pre-IPO Companies were financed by borrowings under
a credit agreement dated May 2, 1997 (the "Original Credit Agreement"). The
Original Credit Agreement provided secured facilities consisting of (a) an 18-
month revolving credit facility providing up to $3 million in revolving loans
(the "Revolving Credit Facility"), (b) a six-year term loan of $20 million to
help fund the acquisition of Airtron (the "Airtron Term Loan"), and (c) a term
loan facility available until October 31, 1998, providing for up to $12
million in term loans having a final maturity six years after the date of the
Original Credit Agreement (the "Acquisition Credit Facility"). Borrowings
under this facility were repaid with proceeds from the IPO.
 
  The results of operations of the acquired businesses are included in the
actual results of operations of the Company from the date of acquisition and
the historical balance sheet at June 30, 1998 includes the acquisitions
completed as of that date. All of the acquisitions are accounted for as
purchases. The cash consideration associated with the acquisition of the IPO
Companies and the Post-IPO Companies was provided by proceeds from the IPO and
borrowings under a credit agreement dated June 12, 1998 (the "Credit
Agreement") and an earlier agreement dated December 11, 1997. The Credit
Agreement is more fully described in the section "Description of Credit
Agreement" on page 53.
 
  The following table sets forth the consideration paid or to be paid in (a)
cash, (b) subordinated debt, (c) shares of non-convertible, non-voting
Preferred Stock to the shareholders of the Pre-IPO Companies and (d) shares of
Common Stock to the shareholders of the Pre-IPO, IPO and Post-IPO Companies.
The Preferred Stock was redeemable at any time after the initial issuance, in
whole or in part, at the option of the Company, at an amount equal to the
liquidation value of $1.00 per share plus any accrued but unpaid dividends.
Redemption of all outstanding Preferred Stock occurred in connection with the
IPO.
 
  For purposes of computing the estimated purchase price for accounting
purposes for the Third Quarter Post-IPO Companies, the value of the Common
Stock is determined using an estimated weighted average fair value of $13.84
per share, which represents a discount rate of 19.6% from the weighted average
stock price of $17.23 at the respective dates of acquisition due primarily to
restrictions on the sale and transferability of such shares. The restrictions
are created by a contractual restriction imposed on the shares issued in
connection with the acquisition of the acquired businesses. This contractual
provision prohibits the shareholders from selling, transferring or otherwise
disposing of any shares for one year following the date of acquisition of such
shares and limiting dispositions for one additional year to no more than 36%
of their holdings.

    NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
  The estimated purchase price and related allocations of the excess purchase
price for the Post-IPO Companies are based upon preliminary estimates and are
subject to certain purchase price adjustments at and following closing. Based
upon management's preliminary analysis, it is anticipated that the historical
carrying value of the assets and liabilities of the Third Quarter Post-IPO
Companies (representing $23.5 million) will approximate fair value. This
results in an allocation to goodwill of approximately $58.0 million.
Management has not identified any other material tangible or identifiable
intangible assets to which a portion of the purchase price could reasonably be
allocated. Amounts in thousands.

4. UNAUDITED PRO FORMA STATEMENT OF OPERATIONS ADJUSTMENTS
 
  a) Reflects the prospective reduction in salaries, bonuses and benefits to
the owners of the GroupMAC Companies to which they have agreed. These
reductions in salaries, bonuses and benefits are in accordance with the terms
of the employment agreements. Such employment agreements are primarily for
three years, contain restrictions related to competition and provide severance
for termination of employment in certain circumstances.
 
  The salaries, bonuses, benefits and other compensation items recorded in the
individual financial statements amounted to $33.4 million, $11.8 million and
$3.1 million for the year ended December 31, 1997 and the six month periods
ended June 30, 1997 and 1998, respectively. The contractually agreed upon
compensation and benefits for these same businesses, on a going forward basis,
amount to $9.5 million, $3.3 million and $1.8 million for the year ended
December 31, 1997 and the six month periods ended June 30, 1997 and 1998,
respectively. The difference between these respective amounts equates to $23.9
million, $8.5 million and $1.3 million and are reflected as pro forma
adjustments.
 
  Also reflects the reduction in compensation expense related to the non-
recurring, non-cash compensation charge of $7.0 million recorded by the
Company in the second quarter of 1997 related to the reverse acquisition of
GroupMAC.
 
  b) Reflects the amortization of goodwill to be recorded as a result of the
acquisitions over a 40-year estimated life.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Group Maintenance America Corp.
 
  We have audited the accompanying balance sheets of Group Maintenance America
Corp. (the Company) as of December 31, 1996 and April 30, 1997, and the
related statements of operations, shareholders' equity (deficit), and cash
flows for the periods from October 21, 1996 (inception) to December 31, 1996
and the four months ended April 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Group Maintenance America
Corp. as of December 31, 1996 and April 30, 1997 and the results of its
operations and its cash flows for the periods from October 21, 1996
(inception) to December 31, 1996 and the four months ended April 30, 1997, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Group Maintenance America Corp. (the Company or GroupMAC Parent) was
incorporated in October 1996 and, therefore, the financial statements reflect
the period since the Company's inception through December 31, 1996 and the
four months ended April 30, 1997. The Company's primary business is to build a
national company providing heating, ventilation and air conditioning (HVAC),
plumbing and electrical services.
 
  Effective April 30, 1997, GroupMAC Parent entered into an Agreement and Plan
of Exchange (the Agreement) with Airtron, Inc. (Airtron), in which $20,366,951
in cash, 14,873,133 shares of GroupMAC Parent preferred stock and 4,652,140
shares of GroupMAC Parent common stock were issued to shareholders of Airtron
in exchange for 100 percent of the then outstanding shares of Airtron. In
connection with this merger the combined company is referred to as GroupMAC
and Subsidiaries. The Agreement closed on May 2, 1997 with the cash portion
funded by the Company's available credit facility and a capital contribution
from a shareholder pursuant to a stock subscription agreement (see note 6).
For accounting purposes, the transaction was accounted for as a reverse
acquisition, as if Airtron acquired GroupMAC Parent, as the former
shareholders of Airtron now own a majority of GroupMAC Parent's common stock.
Concurrent with this transaction, the resulting combined entity will be named
Group Maintenance America Corp. and Subsidiaries. The Company is included in
the consolidated financial statements of GroupMAC and Subsidiaries, presented
elsewhere herein, for periods subsequent to the effective date of the
acquisition.
 
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid debt instruments with original maturities of three months or
less to be cash equivalents. There were no cash payments for interest or
income taxes in 1996 or in the four months ended April 30, 1997.
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures of major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.
 
 Income Taxes
 
  The Company follows the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards No. 109. Under
this method deferred income taxes are recorded based upon differences between
the financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
underlying assets or liabilities are received or settled.

                        GROUP MAINTENANCE AMERICA CORP.
 
                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  The Company has recorded a full valuation allowance against all deferred tax
assets due to the uncertainty of ultimate realizability. Accordingly, no income
tax benefit has been recorded for the losses incurred.

5. LONG-TERM DEBT
 
CREDIT AGREEMENT
 
  In May 1997, the Company entered into a credit agreement (the Credit
Agreement) with a group of banks providing for secured facilities consisting
of an 18-month revolving credit line of $3 million, a six-year term loan of
$20 million used in connection with the acquisition of Airtron (see note 1)
and a term loan facility, available until October 31, 1998, providing for up
to $12 million in term loans having a final maturity six years after the date
of the Credit Agreement, to be used in connection with future acquisitions.
Loans under the revolving credit facility are limited to a borrowing base
consisting of 70% of eligible accounts receivable. Interest on outstanding
borrowings is payable in quarterly installments beginning August 31, 1997. A
commitment fee of .25% is payable on the unused portion of the revolving
credit line.
 
  The Credit Agreement contains covenants which, among other matters, restrict
or limit the ability of the Company to pay dividends, incur indebtedness, make
capital expenditures and repurchase capital stock. The Company must also
maintain a minimum fixed charge coverage ratio (as defined) and certain other
ratios, among other restrictions.
 
  As of June 30, 1997, available borrowing capacity under the Credit Agreement
was $5.4 million.
 
LONG-TERM DEBT
 
  On October 24, 1996, the Company executed a $75,000 subordinated note with a
Texas limited liability company. The note bears interest at eight percent (8%)
and is payable upon the earlier of (i) the closing of the Company's first
public offering of its common stock or (ii) two years from the date of the
note. The note is subordinate to all indebtedness of the Company to the banks
and is guaranteed by certain officers of the Company.
 
6. SHAREHOLDERS' EQUITY (DEFICIT)
 
COMMON STOCK
 
  The Company is authorized to issue 100 million shares of common stock, $.001
par value. There were 1,211,345 and 1,611,345 shares of common stock issued
and outstanding at December 31, 1996 and April 30, 1997, respectively. In
connection with the sale of certain shares of common stock to management, a
nonrecurring, noncash compensation charge of $206,250 was recorded in 1996 to
reflect the difference between the amount paid for the shares and the
estimated fair value of the shares on the date of sale.
 
  On October 24, 1996, the Company entered into a stock subscription agreement
with an individual allowing for the purchase of up to 2.6 million shares of
common stock at a purchase price of $3.08 per share. Under this agreement, 0.2
million shares were purchased in October 1996, 0.2 million in January 1997 and
0.2 million in

  At April 30, 1997, options representing 28,000 shares were available to be
granted under the option agreement.
 
  The Company has adopted the disclosure-only provisions of the Statement of
Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based
Compensation. Accordingly, no compensation cost has been recognized for the
option agreement as all options have an exercise price equal to or greater
than the fair value of the underlying stock at date of grant. Had compensation
cost for the Company's stock option plan been determined consistent with the
provisions of SFAS No. 123, net loss would have been increased by the
following pro forma amounts:

  The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted average
assumptions used by the plan for fiscal 1996 and for the four months ending
April 30, 1997: no dividend yield; expected volatility of 0%; risk-free
interest rate of 6.26%; and expected lives of ten years. The weighted average
fair value per share of the options granted during fiscal 1996 and in the four
months ending April 30, 1997 is estimated to be $1.425.
 
7. INCOME TAXES
 
  There is no Federal income tax provision as losses were incurred and a
valuation allowance has been established against future benefits deriving from
the carryforward of these losses.
 
8. COMMITMENTS AND CONTINGENCIES
 
  The Company has entered into various operating lease agreements, primarily
for office space, furniture and service equipment. Minimum annual rental
payments under non-cancelable operating leases as of June 30, 1997, were
approximately as follows:

             NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
  1. The accompanying unaudited consolidated condensed financial statements of
the Company have been prepared in accordance with Rule 10-01 of Regulation S-X
promulgated by the Securities and Exchange Commission and do not include all
of the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management,
the Company has made all adjustments necessary for a fair presentation of the
results of the interim periods, and such adjustments consist of only normal
recurring adjustments. The results of operations for such interim periods are
not necessarily indicative of results of operations for a full year. The
unaudited consolidated condensed financial statements should be read in
conjunction with the audited consolidated financial statements and notes
thereto of the Company and management's discussion and analysis of financial
condition and results of operations included in the Transition Report on Form
10-K for the ten-month period ended December 31, 1997.
 
  2. Basic earnings per share have been calculated by dividing net income
(loss) by the weighted average number of common shares outstanding. Diluted
earnings per share have been calculated by dividing net income by the weighted
average number of common shares outstanding plus potentially dilutive common
shares.
 
  The following table summarizes weighted average shares outstanding for each
of the historical periods presented (in thousands):

  Because the Company reported a net loss for the three and six month periods
ended June 30, 1997, the potentially dilutive common shares (including
warrants and stock options) had an anti-dilutive effect on earnings per share.
Accordingly, diluted earnings per share is the same as basic earnings per
share for these periods.
 
  3. During the first half of 1998, the Company completed the acquisition of
the Post-IPO Companies for approximately $157.8 million, which includes cash
payments of $85.5 million, $0.8 million of subordinated convertible debt, 5.4
million shares of common stock and options to purchase 0.1 million shares of
Common Stock. Of the total consideration, approximately $5.4 million of cash
and 0.1 million shares of common stock is due to former shareholders at June
30, 1998. All such acquisitions were accounted for as purchases. In connection
with these acquisitions, the Company assumed approximately $15.7 million of
debt. The combined annual revenues of the Post-IPO Companies were
approximately $292.1 million.

  Pro forma adjustments included in the amounts above consist of compensation
differentials, elimination of a non-recurring, non-cash compensation charge of
$7.0 million in 1997 related to the reverse acquisition of Airtron, adjustment
for goodwill amortization over a period of 40 years, elimination of historical
interest expense on long-term debt which was repaid with the proceeds of the
IPO or otherwise retired, additional interest expense on funds borrowed for
acquisitions of certain Post-IPO Companies, and adjustment to the federal and
state income tax provisions based on pro forma operating results. Net income
per share assumes all shares issued for the acquisitions were outstanding from
the beginning of the periods presented. The pro forma amounts above also
include actual corporate overhead costs. These costs increased $1.4 million
and $2.6 million during the three and six month periods ended June 30, 1998
compared to the three and six month periods ended June 30, 1997, respectively
due to the formation of the corporate management team and infrastructure
necessary to execute the Company's operating and acquisition strategies. This
increase amounts to approximately $0.03 and $0.06 per basic and diluted share
in the three and six month periods ended June 30, 1998, respectively.
 
  From June 30, 1998 through August 13, 1998, the Company acquired three
additional platform companies with combined annual revenues of $58.6 million.
Total consideration paid was approximately $19.6 million that included cash
payments of $9.7 million, 0.6 million shares of common stock and options to
purchase 0.2 million shares of common stock. These acquisitions will be
accounted for as purchases.
 
  4. The acquisitions of the Post-IPO Companies included in the accompanying
financial statements were accounted for under the purchase method of
accounting. Purchase price consideration is subject to final adjustment. The
allocation of purchase price to the assets acquired and liabilities assumed
has been initially assigned and recorded based on preliminary estimates of
fair values and may be revised as additional information becomes available.
However, the Company does not expect any significant adjustments to the
purchase price allocations or amount of goodwill at June 30, 1998.
 
  5. The Company is involved in various legal actions. It is not possible to
predict the outcome of these matters; however, in the opinion of management,
the resolution of these matters will not have a material adverse effect on the
Company's consolidated financial position or results of operations.
 
  Many computer software programs, as well as certain hardware and equipment
containing date sensitive data, were structured to utilize a two-digit date
field. Accordingly, these programs may not be able to properly recognize dates
in the year 2000 and later, which could result in significant system and
equipment failures. The Company recognizes that it must take action to ensure
that its products and operations will not be adversely impacted by Year 2000
software failures.

  An initial systems survey of the GroupMAC Companies was completed in March
of 1998 and revealed that several of the Company's business applications
possess Year 2000 problems. The Company has engaged a consulting firm to
assist the Company in assessing exposure related to core business applications
software and developing an action plan to address these issues in a timely
manner. This project commenced in early July and is expected to be completed
in early September. The cost of this assessment is estimated at $80,000. The
major deliverables of the project are as follows:
 
    . Confirming and tracking Year 2000 compliance with software vendors
       currently utilized by the Company.
 
    . Assessing risk and determining an estimated range of costs to remediate
       those applications that are not Year 2000 compliant.
 
    . Developing an action plan for correcting non-compliant applications
       before January 1, 2000.
 
  Once this project is complete, management will have better information
available to assess the impact of the Year 2000 problem and determine the
appropriate corrective actions and the costs thereof.
 
  Additionally, the Company is developing data processing systems throughout
the organization for its overall information needs which will be free of any
Year 2000 limitations. The common data processing system will be implemented
first at GroupMAC Companies with identified Year 2000 constraints that are not
expected to be corrected by other means. The Company expects to commence user-
acceptance testing of the new data processing system before the second quarter
of 1999 with implementation to follow immediately thereafter. The Company
currently does not have an overall estimate of the cost associated with the
purchase and implementation of the new processing system.
 
  The Year 2000 considerations may have an effect on some of the Company's
customers and suppliers, and thus indirectly on the Company. The Company has
not assessed the potential adverse effect on the Company with respect to
customers and suppliers with Year 2000 problems.

consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Group

               GROUP MAINTENANCE AMERICA CORP. AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Group Maintenance America Corp. ("GroupMAC") was incorporated as a Texas
corporation to build a national company providing commercial and residential
heating, ventilation and air conditioning ("HVAC"), plumbing and electrical
services.
 
  Effective April 30, 1997, GroupMAC entered into an Agreement and Plan of
Exchange (the "Agreement") with Airtron, Inc. ("Airtron") and certain of its
shareholders, pursuant to which $20.4 million in cash, 14.9 million shares of
GroupMAC preferred stock and 4.7 million shares of GroupMAC common stock were
issued to shareholders of Airtron in exchange for all of the then outstanding
shares of Airtron.
 
  Although for legal purposes Airtron was acquired by GroupMAC, for accounting
purposes, the transaction was accounted for as a reverse acquisition, as if
Airtron acquired GroupMAC, due to the fact that the former shareholders of
Airtron then owned a majority of GroupMAC common stock. In connection with the
purchase of GroupMAC, the consideration paid to the shareholders of GroupMAC
was recorded as nonrecurring compensation expense of $7.0 million in the
accompanying statements of operations for the ten months ended December 31,
1997. The consolidated financial statements presented herein for the periods
prior to the effective date of the acquisition only include the accounts of
Airtron. The consolidated statements of shareholders' equity have been
converted from Airtron's capital structure to GroupMAC's capital structure to
reflect the exchange of shares pursuant to the Agreement. The cash and
redeemable preferred stock paid to the Airtron shareholders, net of existing
liabilities to former shareholders, has been treated as a distribution to the
Airtron shareholders. The consolidated group of companies are collectively
referred to herein as GroupMAC and Subsidiaries or the "Company." All
significant intercompany balances have been eliminated. Concurrent with the
initial public offering of GroupMAC's common stock (the "IPO"), the Company
changed its fiscal year end fromFebruary 28 to December 31.
 
  Airtron was incorporated in 1970 as a Delaware corporation. Airtron installs
and services brand name heating and air conditioning equipment for residential
and commercial customers located in Ohio, Indiana, Kansas, Kentucky, Florida
and Texas.
 
  In June and July 1997, the Company acquired, in separate transactions, 10
additional companies (the "Pre-IPO Companies") through a combination of cash,
preferred stock, common stock and warrants to purchase shares of common stock
of GroupMAC. During the fourth quarter of 1997, the Company acquired,
concurrently with the IPO, 13 additional companies (the "IPO Companies" and,
together with Airtron and the Pre-IPO Companies, the "GroupMAC Companies")
through a combination of cash and common stock of the Company.
 
  The acquisitions of the GroupMAC Companies (other than Airtron) were
accounted for as purchase business combinations, with the results of
operations included in the Company's financial statements from the effective
date of acquisition.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Use of Estimates
 
  The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

<PAGE>
 
               GROUP MAINTENANCE AMERICA CORP. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
from service and maintenance contracts are recognized over the life of
contracts. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost methods. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents. There were no cash payments
for income taxes during the ten months ended December 31, 1997. Cash payments
for income taxes were approximately $2.6 million and $2.5 million for the
fiscal years ended February 28, 1997 and February 29, 1996, respectively. Cash
payments for interest were approximately $1.5 million for the ten months ended
December 31, 1997. Cash payments for interest for the fiscal years ended
February 28, 1997 and February 29, 1996 were not significant.
 
 Inventories
 
  Inventories consist primarily of purchased materials and supplies. The
inventory is valued at the lower of cost or market, with cost determined on a
first-in, first-out ("FIFO") basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed
principally using the straight-line method over the useful lives of the
assets. Leasehold improvements are amortized over the shorter of the remaining
lease term or the estimated useful life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.
 
 Goodwill
 
  Goodwill represents the excess of the aggregate purchase price over the fair
value of net assets acquired and is amortized on a straight-line basis over a
period of 40 years. The Company assesses the recoverability of this intangible
asset by determining whether the amortization of the goodwill balance over its
remaining life can be recovered through undiscounted future operating cash
flows of the acquired operation. The amount of goodwill impairment, if any, is
measured based on projected discounted future operating cash flows compared to
the carrying value of goodwill. The assessment of the recoverability of
goodwill will be impacted if estimated future operating cash flows are not
achieved.
 
 Debt Issue Costs
 
  Debt issue costs related to the Company's Credit Agreement dated December
11, 1997 (see Note 7) are included in other noncurrent assets and amortized to
interest expense over the scheduled maturity of the debt.
 
 Stock-Based Compensation
 
  Statement of Financial Accounting Standards ("SFAS") No. 123, Accounting for
Stock-Based Compensation, encourages but does not require companies to record
compensation cost for stock-based employee compensation plans at fair value.
The Company has chosen to continue to account for stock-based compensation
 
                                     F-39
<PAGE>
 
               GROUP MAINTENANCE AMERICA CORP. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
using the intrinsic value method prescribed in Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees, and related
Interpretations. Accordingly, compensation cost for stock options is measured
as the excess, if any, of the quoted market price of GroupMAC's common stock
at the date of the grant over the amount an employee must pay to acquire the
common stock.
 
 Warranty Costs
 
  The Company generally warrants all of its work for a period of one year from
the date of installation. A provision for estimated warranty costs is made at
the time a product is sold or service is rendered.
 
 Income Taxes
 
  The Company uses the asset and liability method to account for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
 Earnings Per Share
 
  In February 1997, the Financial Accounting Standards Board (the "FASB")
issued SFAS No. 128, Earnings Per Share, which the Company is required to
adopt for both interim and annual periods ending after December 15, 1997. SFAS
No. 128 simplifies the earnings per share calculation. Basic earnings per
share, which excludes the impact of common share equivalents, replaces primary
earnings per share. Diluted earnings per share, which utilizes the average
market price per share as opposed to the greater of the average market price
per share or ending market price per share when applying the treasury stock
method in determining common share equivalents, replaces fully diluted
earnings per share.
 
  Weighted average shares outstanding for each of the periods presented were
as follows (in thousands):

  Basic earnings per share have been calculated by dividing net income (loss)
by the weighted average number of common shares outstanding. Diluted earnings
per share are typically computed by dividing net income by the weighted
average number of common shares outstanding plus potentially dilutive common
shares. Because the Company reported a net loss for the ten months ended
December 31, 1997, the potentially dilutive

common shares (including warrants and stock options discussed in Note 9) had
an anti-dilutive effect on earnings per share. Accordingly, diluted earnings
per share is the same as basic earnings per share for each of the periods
presented.
 
3. BUSINESS COMBINATIONS
 
  During June and July 1997, the Company acquired the Pre-IPO Companies for
approximately $12.5 million in cash, 1.4 million shares of common stock, 4.4
million shares of redeemable preferred stock (which were retired in connection
with the IPO), options to acquire 60,000 shares of common stock and warrants
to purchase 514,000 shares of common stock. Of the total consideration,
approximately $0.4 million of cash and 22,500 shares of common stock is due to
former owners at December 31, 1997.
 
  During the fourth quarter of 1997, the Company acquired the IPO Companies
for approximately $31.7 million in cash, 3.1 million shares of common stock
and 42,000 options to acquire shares of common stock. Of the total
consideration, approximately $2.8 million of cash and 0.3 million shares of
common stock is due to former owners at December 31, 1997.
 
  In conjunction with the above mentioned acquisitions the Company assumed
$16.1 million of debt.
 
  For the above mentioned acquisitions, the common stock was valued at its
estimated fair value at the time of the respective acquisition and the
preferred stock was valued at its redemption value of $1 per share. The
allocation of purchase price to the assets acquired and liabilities assumed
has been initially assigned and recorded based on preliminary estimates of
fair value and may be revised as additional information becomes available.
However, the Company does not expect any significant adjustments to the
purchase price allocations or amount of goodwill at December 31, 1997.
 
  Several former owners of the GroupMAC Companies have the ability to receive
additional amounts of purchase price, payable in cash and common stock in 1998
through 2000, contingent upon the occurence of future events. The Company will
record such contingent consideration as additional purchase price when earned.
 
  The unaudited pro forma data presented below consists of the combined income
statement data for GroupMAC, Airtron and the other GroupMAC Companies as if
the acquisitions were effective on the first day of the period being reported
(in thousands, except for per share amounts).

  On May 2, 1997, the Company entered into a credit agreement (the "Original
Credit Agreement") with a total commitment of $35 million. The Original Credit
Agreement consisted of three portions: (i) a revolving credit agreement
providing up to $3 million for use as working capital, (ii) a $12 million
advancing acquisition line of credit to finance acquisitions, and (iii) a $20
million term loan to finance the acquisition of Airtron. Borrowings under the
Original Credit Agreement totaled $32.5 million to fund the cash portion of
the purchase prices related to Airtron and the Pre-IPO Companies. The Original
Credit Agreement was repaid from the proceeds of the IPO and terminated in
December 1997.
 
  In connection with the acquisition of certain IPO Companies taxed under
Subchapter S of the Internal Revenue Code, distributions totalling $4.2
million were made to former shareholders, with $1.8 million paid from acquired
cash and $2.5 million satisfied with a note to the selling shareholders. These
notes bear interest at 6% and are payable in May 1998.
 
  On December 11, 1997, the Company entered into a three-year revolving credit
agreement (the "Credit Agreement") with an initial borrowing capacity of $75
million. Borrowings under the Credit Agreement bear interest either at the
prime rate or Eurodollar rate adjusted for margins ranging from 0% to 0.5% or
1.0% to 2.0%, respectively, depending on the ratio of the Company's funded
debt to its historical earnings before interest,

taxes, depreciation and amortization. The Company is subject to commitment
fees ranging from 0.25% to 0.375% for the unutilized portion under the Credit
Agreement. Under the Credit Agreement, the Company is required to maintain (i)
a minimum fixed charge coverage ratio; (ii) a minimum tangible net worth that
is positive; (iii) a maximum ratio of total indebtedness for borrowed money to
capitalization (as defined in the Credit Agreement); (iv) a maximum ratio of
debt to historical earnings before interest, taxes, depreciation and
amortization; (v) a maximum amount of third party indebtedness in relation to
consolidated shareholders' equity; and (vi) a minimum amount of consolidated
net worth (as defined in the Credit Agreement). The Credit Agreement places
limitations upon the amount of letters of credit which may be drawn,
investments which may be permitted (as defined in the Credit Agreement), and
liens which may be granted to secure other debt. The Company may not pay any
dividends or redeem, retire or guarantee the value of shares of any class of
stock in the Company without prior approval from the lending banks, other than
the purchase of outstanding shares of the Company's stock within defined
limits. The Credit Agreement matures on December 11, 2000.

8. DUE TO RELATED PARTIES (NONCURRENT)
 
  Under the Agreement, part of the cash purchase price payable to former
shareholders relates to the tax benefits which will be received by the Company
related to the exercise of previously outstanding warrants and distributions
under deferred compensation arrangements. A liability of $9.7 million has been
recognized in the accompanying consolidated financial statements for an
estimate of these amounts as of December 31, 1997. This amount will be funded
to the former shareholders as the tax benefit is realized by the Company
either through receipt of net operating loss carryback claims or utilization
of current deductions and net operating loss carryforwards to reduce estimated
tax payments. As such tax benefits are not expected to be realized by December
31, 1998, the $9.7 million liability and the related refundable income taxes
and deferred tax assets have all been reflected as long-term in the
accompanying consolidated balance sheet.
 
9. STOCK-BASED COMPENSATION PLANS
 
  The Group Maintenance America Corp. 1997 Stock Awards Plan was adopted by
the Board of Directors of GroupMAC to further promote and align the interests
of directors, key employees and other persons providing services to the
Company with those of its shareholders. Pursuant to this plan and a stock
option plan for non-management employees, on November 6, 1997, GroupMAC
granted options to purchase approximately 1.9 million shares of common stock
at an exercise price equal to the IPO price of $14.00 per share. These options
vest at a rate of 25% per year for four years on the anniversary of the grant
date and expire on November 6, 2002. The cumulative number of shares of common
stock that may be issued under both plans may not exceed 12% of the number of
shares outstanding (determined quarterly), subject to adjustment for corporate
transactions and changes that affect GroupMAC, its shares or share status.
Both stock option plans expire on June 30, 2007.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
  Additionally, the Company granted to directors, senior management and other
employees options to purchase an aggregate of 388,800 shares of common stock
at an exercise price of $3.08. During 1997, options to purchase 20,000 shares
of common stock were exercised, 25,000 options terminated and the remaining
options were outstanding at December 31, 1997. These options vest and expire
over various periods.
 
  In connection with the purchase of one of the Pre-IPO Companies, the Company
issued warrants to purchase 514,000 shares of common stock at $17.50.
 
  The following is a summary of stock option and warrant activity (in

  The Company applies Accounting Principle Board Opinion No. 25, Accounting
for Stock Issued to Employees, in accounting for its stock option plans.
Accordingly, compensation cost has been recognized only for the options that
have an exercise price less than the fair market value of the underlying stock
at date of grant. A compensation charge of $0.2 million is reflected in the
consolidated statements of operations and shareholders' equity for the ten
months ended December 31, 1997 related to the issuance of management shares
and stock options at prices below the fair market value at the date of issue
or grant.
 
  The following unaudited pro forma data is calculated as if compensation
expense for the Company's stock option plans were determined based on the fair
value at the grant date for awards under these plans consistent with the
methodology prescribed under SFAS No. 123, Accounting for Stock-Based
Compensation:

  In July 1994, Airtron granted warrants to purchase 60,000 common shares at
$1 each until August 1, 2011. The appraised value of Airtron's stock at that
time was $40 per share, resulting in a charge of $2.4 million and an
offsetting increase in retained earnings in fiscal 1995. All 60,000 warrants
were outstanding at February 29, 1996. In August 1996, 15,000 of these
warrants were purchased from a former shareholder for $0.5 million, resulting
in a reduction in retained earnings for the original recorded value of the
warrants of $0.6 million with the offset recorded as other income. At February
28, 1997, 45,000 warrants were outstanding. In connection with the Agreement
these warrants were exchanged for cash and preferred and common shares of
GroupMAC.
 
  Airtron had deferred compensation arrangements for certain members of its
management and its board of directors. The assets and liabilities previously
recorded by the Company have been reflected as distributions in the
accompanying financial statements.
 
10. SHAREHOLDERS' EQUITY
 
  On October 24, 1996, the Company entered into a stock subscription agreement
with an individual providing for the sale of up to 2.6 million shares of
common stock at a purchase price of $3.08 per share. At December 31, 1997, the
Company had sold all of the 2.6 million shares.
 
  On August 16, 1997, the Board of Directors of GroupMAC approved a 1-for-2.5
reverse stock split on the Company's common stock. The reverse stock split was
approved by the shareholders of GroupMAC on September 24, 1997 and became
effective shortly thereafter. All share and per share data have been restated
to reflect the reverse stock split.
 
  During November and December 1997, the Company completed the IPO involving
the sale of 8.3 million shares of common stock at a price to the public of
$14.00 per share. The net proceeds from the IPO (after deducting underwriting
discounts and commissions and offering expenses) were approximately $103.6
million. Of this amount, $29.8 million was used to pay the cash portion of the
closing consideration relating to the acquisitions of one Pre-IPO Company and
the IPO Companies, $42.6 million to repay corporate indebtedness and debt
assumed in connection with the acquisition of the GroupMAC Companies, $19.3
million to retire all of

1997 and the years ended February 28, 1997 and February 29, 1996,
respectively.
 
  Certain of the GroupMAC Companies make contributions to union-administered
benefit funds which cover the majority of these companys' employees. For the
ten months ended December 31, 1997, the participant costs charged to
operations were approximately $0.6 million. Governmental regulations impose
certain requirements relative to multi-employer plans. In the event of plan
termination or employer withdrawal, an employer may be liable for a portion of
the plan's unfunded vested benefits, if any. The Company has not yet received
information from the plans' administrators to determine its share of any
unfunded vested benefits. The Company does not anticipate withdrawal from the
plans, nor is the Company aware of any expected plan terminations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
14. COMMITMENTS AND CONTINGENCIES
 
  The Company is involved in various legal actions. It is not possible to
predict the outcome of these matters; however, in the opinion of management,
the resolution of these matters will not have a material adverse effect on the
Company's consolidated financial position or results of operations.
 
  Many computer software programs, as well as certain hardware and equipment
containing date sensitive data, were structured to utilize a two-digit date
field meaning that they may not be able to properly recognize dates in the
year 2000 and later. This could result in significant system and equipment
failures. The Company recognizes that it must take action to ensure that its
products and operations will not be adversely impacted by Year 2000 software
failures and is currently developing detailed assessments and action plans to
address Year 2000 issues. Irrespective of the Year 2000 issue, the Company is
in the process of developing data processing systems throughout the
organization for its overall information needs which will be free of any Year
2000 limitations. The common data processing system will be implemented first
at GroupMAC Companies with identified Year 2000 constraints which are not
expected to be corrected by other means. The Company expects to commence user-
acceptance testing of the new data processing system by the end of 1998 with
implementation beginning in 1999. The Company currently does not have an
overall estimate of the cost associated with the purchase and implementation
of the new processing system.
 
  The Year 2000 considerations may have an effect on some of the Company's
customers and suppliers, and thus indirectly on the Company. The Company has
not assessed the potential adverse effect on the Company with respect to
customers and suppliers with Year 2000 problems.
 
15. FINANCIAL INSTRUMENTS
 
  The Company's financial instruments consist of cash and cash equivalents,
restricted investments (carried at cost--see Note 4) and debt. The Company
believes that the carrying values of these instruments on the accompanying
consolidated balance sheets approximate their fair value.
 
16. SUBSEQUENT EVENTS (UNAUDITED)
 
  During the first quarter of 1998, the Company completed the acquisition of
15 platform and four tuck-in companies (the "Post-IPO Companies"). The
combined annual revenues of the Post-IPO Companies were approximately $155.0
million. Total consideration paid was $68.5 million, which included cash
payments of $36.9 million, $0.8 million of subordinated convertible debt, and
2.5 million shares of common stock. All such acquisitions will be accounted
for as purchases.
 
  The Company has signed definitive agreements to purchase two platform
companies with combined annual revenues of $28.4 million. Total consideration
to be paid is approximately $21.7 million which includes cash payments of
$11.9 million, and 0.8 million shares of common stock. Both acquisitions will
be accounted for as purchases.

                         INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors
MacDonald-Miller Industries, Inc.
 
  We have audited the accompanying consolidated balance sheets of MacDonald-
Miller Industries, Inc. and subsidiaries as of December 31, 1995, 1996 and
June 30, 1997, and the related consolidated statements of income,
shareholders' equity and cash flows for each of the three years ended December
31, 1996, and the six-month period ended June 30, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of MacDonald-
Miller Industries, Inc. and subsidiaries as of December 31, 1995 and 1996, and
June 30, 1997, and the results of their operations and cash flows for each of
the three years ended December 31, 1996 and the six-month period ended June
30, 1997 in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  MacDonald-Miller Industries, Inc. (the Company) (MMI), a Washington
corporation, is a mechanical contractor and service company engaged in the
design, installation and maintenance of heating, ventilating, air
conditioning, plumbing, refrigeration, and automated control systems for
commercial and industrial properties. The main areas of operation are in the
states of Washington and Oregon.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Presentation and Principles of Consolidation
 
  On August 18, 1997, the Company signed an agreement and plan of merger with
Group Maintenance America Corp. (GroupMAC), whereby GroupMAC will acquire the
Company in a merger transaction for a combination of cash and common shares of
GroupMAC. The merger will close concurrent with the closing of the initial
public offering of the common stock of GroupMAC (the "GroupMAC IPO"). Prior to
the closing of the acquisition, the Company will distribute the net assets of
MacDonald-Miller Residential (MMR) (a division of MMI), to its shareholders,
in a tax-free distribution. See Note 17.
 
  The accompanying financial statements exclude MMR, include only the
operations of MMI to be acquired in the merger and have been prepared on the
basis that the distribution of the net assets of MMR had been completed as of
December 31, 1993. Therefore, these financial statements do not include any of
the net assets or operations of MMR for the periods presented which were
included in previously issued financial statements of MMI. Effects of
adjustments related to the unconsolidated affiliate have been shown as a
reduction in shareholders' equity for each of the years presented.
 
  The following provides summary financial information of MMI, including MMR,
as presented in previously issued financial statements:

              MACDONALD-MILLER INDUSTRIES, INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Amounts reported as due from affiliate in the accompanying balance sheets
represent the allocation of bank borrowings attributed to MMR and are expected
to be remitted to the Company at the completion of the planned acquisition as
separate financing of the division is established.
 
  The consolidated financial statements include the accounts of MacDonald-
Miller Industries, Inc. and its wholly-owned subsidiaries MacDonald-Miller
Co., Inc. and MacDonald-Miller Service, Inc. (collectively "the Company").
Intercompany balances and transactions are eliminated in consolidation.
 
 Interim Financial Information
 
  The interim financial statements as of June 30, 1996 and September 30, 1997
and for the six and nine months then ended, respectively, are unaudited, and
certain information and footnote disclosures have been omitted. In the opinion
of management, all adjustments, consisting of only normal recurring
adjustments, necessary to fairly present the financial position, results of
operations and cash flows with respect to the interim financial statements,
have been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
Significant estimates used in preparing these financial statements include
estimated costs to complete contracts in progress which have a direct effect
on gross profit.
 
 Revenue Recognition
 
  Revenues from fixed-price and modified fixed-price construction contracts
are recognized on the percentage-of-completion basis using the cost-to-cost
method. This method is used because the Company considers contract costs to be
the best available measure of progress on these contracts. Revenues from cost-
plus-fee contracts are recognized on the basis of costs incurred during the
period plus the fee earned, measured by the same method. Provisions for
estimated losses on uncompleted contracts are made in the period in which such
losses are determined. Changes in job performance, job conditions, estimated
profitability and final contract settlements may result in revisions to costs
and revenues and are recognized in the period in which the revisions are
determined.
 
 Inventories
 
  Inventories consist of parts and supplies used in the Company's operations.
The inventories are valued at the lower of cost (determined using the first-
in, first-out method) or market.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using
straight-line and accelerated methods over the useful life of the assets.
Leasehold improvements are amortized over the life of the related lease.
 
 Disbursements in Transit
 
  Under the Company's cash management system, checks issued, but not presented
to the bank frequently result in overdraft balances for financial accounting
purposes. These balances are classified as accounts payable in the balance
sheets and as a financing activity in the statements of cash flows.

              MACDONALD-MILLER INDUSTRIES, INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 Warranty Costs
 
  The Company warrants labor for one year on new construction and 90 days
after servicing of air conditioning and heating units. A reserve for warranty
costs is recorded upon completion of installation or services.
 
 Stock-Based Compensation
 
  Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards No. 123, Accounting for Stock-Based Compensation (SFAS
No. 123). The new standard measures compensation cost using a fair value
method, which computes compensation cost as the difference between the
options' fair value and the option price on the grant date. However, SFAS No.
123 allows companies to continue to measure compensation cost using the
intrinsic value method, which computes compensation cost as the difference
between a company's stock price and the option price at the grant date. The
Company has elected to continue to use the intrinsic value method.
 
 Income Taxes
 
  Income taxes are accounted for using an asset and liability approach which
requires the recognition of deferred tax liabilities and assets for the
expected future tax consequences of temporary differences between the
financial statement and tax basis of assets and liabilities at the applicable
enacted tax rates. Income taxes are explained further in Note 9.
 
 Fair Value of Financial Instruments
 
  The Company's financial instruments include cash and cash equivalents,
billed receivables, loans, short-term debt (a revolving line of credit with a
variable interest rate) and long-term debt. The carrying value of these
instruments approximate fair value.
 
 Asset Impairment
 
  Effective January 1, 1996, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.
 
 Reclassifications
 
  Certain amounts in the financial statements for 1994 and 1995 have been
reclassified to conform with the 1996 presentation. These changes had no
effect on operating results.

  In 1989, several key employees were granted options to purchase 25,000

share. The options vest and become exercisable in substantially equal annual
amounts through December 1998. Unexercised options expire one year after

  Upon successful completion of the sale of MMI, all options in the key
employees plan will be vested and exercised. The employee plan will be
eliminated.
 
 Incentive Compensation Plan
 
  During 1995, the Board of Directors established an Incentive Compensation
Plan (ICP) on behalf of executive management. The ICP provides that a portion
of net income, in excess of an established rate of return on equity, be
expensed as incentive compensation. The 1996 and 1995 incentive compensation
expense is $10,000 and $710,000, respectively. There was no expense for the
period ending June 30, 1997 and 1996. The deferred portion at December 31,
1996 and 1995 of $190,000 and $355,000 is payable in future years depending on
operating results of the Company. In the event of operating losses, the
deferred pool will be reduced by the lesser of the operating loss, or the
deferred pool. Participation in the ICP is subject to certain employment and
vesting provisions. The deferred amounts are subordinated to bank and surety
credits.

14. CONCENTRATIONS OF CREDIT RISK
 
  Financial instruments which potentially subject the Company to
concentrations of credit risk consist of receivables and costs and earnings in
excess of billings on uncompleted contracts. Concentrations of credit risk
with respect to billed and unbilled receivables are limited due to the large
number of customers comprising the Company's customer base. The Company
generally does not require collateral, but in most cases can place liens
against the property constructed if a default takes place.
 
15. SIGNIFICANT CUSTOMERS
 
  During the period ending June 30, 1997, the Company had $17,706,000 or 45%
of the periods revenues, and $6,840,000 or 45% of the ending accounts
receivable from two customers. The accounts receivable and revenue represent
four jobs.

                         INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors of
 Masters, Inc.
Gaithersburg, Maryland
 
  We have audited the accompanying balance sheets of Masters, Inc. as of
December 31, 1995, December 31, 1996 and June 30, 1997, and the related
statements of operations, shareholders' equity and cash flows for each of the
three years in the period ended December 31, 1996 and for the six month period
ended June 30, 1997. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, such financial statements present fairly, in all material
respects, the financial position of Masters, Inc., as of December 31, 1995,
December 31, 1996 and June 30, 1997, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1996
and for the six month period ended June 30, 1997 in conformity with generally
accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Masters, Inc. (the Company) is a Mechanical Contractor primarily engaged in
the installation of residential and commercial plumbing, heating, air
conditioning and sprinkler systems within a 100-mile radius of the Washington,
D.C. area.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the six months ended June 30, 1996 and
as of September 30, 1997 and for the nine months ended September 30, 1996 and
1997 are unaudited, and certain information and footnote disclosures, normally
included in financial statements prepared in accordance with generally
accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the interim financial statements, have been
included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reported period. Actual results could differ from these estimates.
 
 Revenue Recognition
 
  The Company reports revenues from long-term construction contracts in
progress based on the percentage-of-completion method of accounting and,
therefore, takes into account the costs, estimated earnings and revenues to
date on contracts not yet completed.
 
  The amount of revenue recognized at the statement date is the portion of the
total contract price that the cost expended to date bears to the anticipated
final total cost, based on current estimates of the cost to complete. Revenue
recognized is not necessarily related to the progress billings to customers.
 
  As contracts extend over one or more years, revisions in estimates of cost
and earnings during the course of the work are reflected in the accounting
period in which the facts which require the revision become known.
 
  At the time a loss on a contract becomes known, the entire amount of the
estimated loss is recognized in the financial statements.
 
 Cash and Cash Equivalents
 
  The Company has a cash management system with its bank that provides for the
investment of excess cash balances. The bank transfers the Company's excess
cash balances daily to investments that are under the bank's control. At
December 31, 1995, December 31, 1996 and June 30, 1997, the balances invested
under the cash management system were $1,294,005, $1,198,620 and $1,106,523,
respectively. The Company considers its investments with initial maturities of
less than 90 days to be cash equivalents.

Inventories are stated at the lower of cost or market with cost determined on
a first-in, first-out basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed by the
straight-line method based on the estimated useful lives of the assets.
Leasehold improvements are depreciated over the lesser of the remaining lease
term or the estimated useful life of the asset. Expenditures for repairs and
maintenance are charged to expense when incurred. Expenditures for major
renewals and betterments, which extend the useful lives of existing equipment,
are capitalized and depreciated. Upon retirement or disposition of property or
equipment, the cost and related accumulated depreciation are removed from the
accounts and any resulting gain or loss is recognized in the statement of
operations.
 
 Warranty Costs
 
  The Company provides one to two year warranties on their contracts. At
December 31, 1995, December 31, 1996 and June 30, 1997, the Company's warranty
reserve was $80,000, $159,000 and $192,388, respectively.
 
 Income Taxes
 
  The Company has elected to be taxed under Subchapter S of the Internal
Revenue Code. Accordingly, the current taxable income of the Company is
taxable to the shareholder who is responsible for the payment of taxes
thereon.
 
 New Accounting Pronouncement
 
  Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting for
the Impairment of Long Lived Assets and for Long-Lived Assets to be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets, may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.
 
 Reclassification
 
  Certain amounts reported in the 1995 and 1996 financial statements have been
reclassified to conform with the June 30, 1997 presentation.

                                MARCH 31, 1997
 
1. BUSINESS AND ORGANIZATION
 
  K & N Plumbing, Heating and Air Conditioning, Inc., (the Company) is
primarily engaged in the business of installing plumbing, heating and air
conditioning systems for new single-family detached homes in the areas in and
around Dallas and Austin, Texas and Las Vegas, Nevada. In addition, the
Company is involved in the replacement and repair market.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Cash and Cash Equivalents
 
  For purposes of the statement of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest and taxes were $99,838 and
$114,955, respectively, for the year ended March 31, 1997.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis, using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Inventories
 
  Inventories consist primarily of purchased materials and supplies. The
inventory is valued at the lower of cost or market, with cost determined on a
first-in, first-out (FIFO) basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease-term or the
estimated life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statement of operations.

 Warranty Costs
 
  The Company warrants labor for one to two years after installation of new
air conditioning and heating units. The Company generally warrants labor for
one year after servicing of existing air conditioning and heating units. A
reserve for warranty costs is recorded upon completion of installation or
service.
 
 Income Taxes
 
  The Company uses the asset and liability method to account for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
 New Accounting Pronouncement
 
  Effective April 1, 1996, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.

The Board of Directors
A-ABC Appliance, Inc. and
 A-1 Appliance & Air Conditioning, Inc.:
 
  We have audited the accompanying combined balance sheets of A-ABC Appliance,
Inc. and A-1 Appliance & Air Conditioning, Inc. (collectively referred to as
the Company) as of December 31, 1996 and May 31, 1997, and the related
combined statements of operations, shareholders' equity and cash flows for the
year ended December 31, 1996 and the five months ended May 31, 1997. These
combined financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these combined
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of A-ABC Appliance,
Inc. and A-1 Appliance & Air Conditioning, Inc. as of December 31, 1996 and
May 31, 1997, and the results of its operations and its cash flows for the

                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  A-ABC Appliance, Inc. (A-ABC) and A-1 Appliance & Air Conditioning, Inc. (A-
1), (collectively referred to as the Company), are under common ownership. As
common control exists among the entities, the financial statements have been
combined for all periods presented. There have been no intercompany
transactions between the entities. A-ABC and A-1 are primarily engaged in the
installation and servicing of heating and air conditioning systems, as well as
home appliances, for residential and light commercial customers in the Dallas,
Texas area.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim combined financial statements for the five months ended May 31,
1996 are unaudited, and certain information and footnote disclosures, normally
included in financial statements prepared in accordance with generally
accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the combined interim financial statements, have
been included. The results of operations for the interim periods are not
necessarily indicative of the results of the entire fiscal year.
 
 Use of Estimates
 
  The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Revenue is recognized upon completion of service. Revenues on service and
maintenance contracts are recognized over the life of the contract.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest were $92,052 and $34,313 for
the year ended December 31, 1996 and the five months ended May 31, 1997,
respectively.
 
 Inventories
 
  Inventories consist primarily of purchased materials and supplies. The
Company uses the first-in, first-out (FIFO) cost method to value its
inventories.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated useful life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated.

<PAGE>
 
       A-ABC APPLIANCE, INC. AND A-1 APPLIANCE & AIR CONDITIONING, INC.
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
Upon retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.
 
 Income Taxes
 
  The shareholders of the Company have elected to be taxed for federal tax
purposes as an S Corporation whereby the shareholders' respective equitable
shares in the taxable income of the Company are reportable on their individual
tax returns. The Company will make distributions to the shareholders each year
at least in amounts necessary to pay personal income taxes payable on the
Company's taxable income.
 
 New Accounting Pronouncement
 
  Effective January 1, 1996, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.

5. GOODWILL AND OTHER NONCURRENT ASSETS
 
  Goodwill represents the excess of the aggregate purchase price over the fair
value of net assets acquired and is amortized on a straight-line basis over a
period of 40 years. The Company assesses the recoverability of this intangible
asset by determining whether the amortization of the goodwill balance over its
remaining life can be recovered through undiscounted future operating cash
flows of the acquired operation. The amount of goodwill impairment, if any, is
measured based on projected discounted future operating cash flows compared to
the carrying value of goodwill. The assessment of the recoverability of
goodwill will be impacted if estimated future operating cash flows are not
achieved.
 
  Other noncurrent assets include a covenant not to compete and deferred
charges related to the "Asset Purchase and Sale Agreement" made between the
Company's shareholders and former owners. The covenant not to compete and
deferred charges are amortized on a straight-line basis for a period of five
years, which is the period of the covenant in the agreement.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Arkansas Mechanical Services, Inc. (AMS) and Mechanical Services, Inc.
(MSI), (collectively referred to as the Company), are under common ownership.
As common control exists among the entities, the financial statements have
been combined for all periods. All significant intercompany transactions and
balances have been eliminated in combination. The Company is primarily engaged
in the installation and servicing of heating and air conditioning systems for
commercial and industrial customers in Little Rock and Fayetteville, Arkansas
and the surrounding areas.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim combined financial statements for the six months ended June 30,
1996 and as of September 30, 1997 and for the nine months ended September 30,
1996 and 1997 are unaudited, and certain information and footnote disclosures,
normally included in financial statements prepared in accordance with
generally accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the combined interim financial statements, have
been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which losses are
determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest were $51,408 and $32,160 for
the year ended December 31, 1996 and the six months ended June 30, 1997.
 
 Inventories
 
  Inventories consist primarily of purchased materials and supplies. The
Company uses the first-in, first-out (FIFO) cost method to value its
inventories.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.
 
 Warranty Costs
 
  The Company warrants labor for the first year after installation on new air
conditioning and heating units. The Company generally warrants labor for 90
days after servicing of existing air conditioning and heating units. A reserve
for warranty costs is recorded upon completion of installation or service.
 
 Income Taxes
 
  The shareholders of the Company have elected to be taxed for federal tax
purposes as an S Corporation whereby the shareholders' respective equitable
shares in the taxable income of the Company are reportable on their individual
tax returns. The Company will make distributions to the shareholders each year
at least in amounts necessary to pay personal income taxes payable on the
Company's taxable income.
 
 New Accounting Pronouncement
 
  Effective January 1, 1996, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.

6. GOODWILL
 
  Goodwill represents the excess of the aggregate purchase price over the fair
value of net assets acquired and is amortized on a straight-line basis over a
period of 40 years. The Company assesses the recoverability of this intangible
asset by determining whether the amortization of the goodwill balance over its
remaining life can be recovered through undiscounted future operating cash
flows of the acquired operation. The amount of goodwill impairment, if any, is
measured based on projected discounted future operating cash flows compared to
the carrying value of goodwill. The assessment of the recoverability of
goodwill will be impacted if estimated future operating cash flows are not
achieved.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Callahan Roach Products and Publications, Inc., (the Company) is primarily
engaged in the business of selling marketing products and pricing models to
independent service companies which install and service heating and air
conditioning systems nationally.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  Interim financial statements as of June 30, 1997 and for the four months
ended June 30, 1996 and 1997, are unaudited, and certain information and
footnote disclosures, normally included in financial statements prepared in
accordance with generally accepted accounting principles, have been omitted.
In the opinion of management, all adjustments, consisting only of normal
recurring adjustments, necessary to fairly present the financial position,
results of operations and cash flows with respect to the interim financial
statements, have been included. The results of operations for the interim
periods are not necessarily indicative of the results for the entire fiscal
year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue and Cost Recognition
 
  Revenues from service contracts are recognized as services are performed.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest and taxes were $9,196 and
$3,123, respectively, for the year ended February 28, 1997.
 
 Inventories
 
  Inventories consists of supplies used in providing the Company's products
and services. The inventory is valued at the lower of cost or market, with
cost determined on a first-in, first-out (FIFO) basis.
 
 Property, Equipment and Depreciation
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.

                CALLAHAN ROACH PRODUCTS AND PUBLICATIONS, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 Income Taxes
 
  The Company uses the asset and liability method to account for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
 New Accounting Pronouncement
 
  Effective March 1, 1996, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets, may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.

</TABLE>
 
4. INCOME TAXES
 
  There is no Federal income tax provision as losses were incurred and a
valuation allowance has been established against future benefits deriving from
the carryforward of these losses. The deferred income tax liability results
primarily from tax depreciation in excess of book depreciation on property and
equipment.

statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

                   CENTRAL CAROLINA AIR CONDITIONING COMPANY
 
                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION
 
  Central Carolina Air Conditioning Company (the Company) is primarily engaged
in the installation and servicing of heating and air conditioning systems for
residential and commercial customers in the Greensboro and Winston Salem,
North Carolina areas.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the eight months ended June 30, 1996
and as of September 30, 1997 and for the eleven months ended September 30,
1996 and 1997, are unaudited, and certain information and footnote
disclosures, normally included in financial statements prepared in accordance
with generally accepted accounting principles, have been omitted. In the
opinion of management, all adjustments, consisting only of normal recurring
adjustments, necessary to fairly present the financial position, results of
operations and cash flows with respect to the interim financial statements,
have been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid debt instruments with a maturity of three months or less to be
cash equivalents. Cash payments for interest were $9,841 and $3,087 for the
year ended October 31, 1996 and the eight months ended June 30, 1997,
respectively.
 
 Inventories
 
  Inventories consist of parts and supplies used mainly in the service portion
of the Company's operation. The inventory is valued at the lower of cost or
market, with cost determined on a first-in, first-out (FIFO) basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated life of the asset.

<PAGE>
 
                   CENTRAL CAROLINA AIR CONDITIONING COMPANY
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.
 
 Warranty Costs
 
  The Company warrants labor for the first year after installation on new air
conditioning and heating units. The Company also offers an extended service
warranty on sales of air conditioning and heating units, for coverage up to
five years after installation. The Company generally warrants labor for 90
days after servicing of existing air conditioning and heating units. A reserve
for warranty costs is recorded upon completion of installation or service.
 
 Income Taxes
 
  The shareholders of the Company have elected to be taxed for federal and
North Carolina tax purposes as an S Corporation whereby the shareholders'
respective equitable shares in the taxable income of the Company are
reportable on their individual tax returns. The Company makes distributions to
the shareholders' each year at least in amounts necessary to pay personal
income tax payable on the Company's taxable income.
 
 New Accounting Pronouncement
 
  Effective November 1, 1995, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.

                HALLMARK AIR CONDITIONING, INC. AND SUBSIDIARY
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION
 
  Hallmark Air Conditioning, Inc. and subsidiary (the Company) is primarily
engaged in the installation and servicing of heating and air conditioning
systems for residential and light commercial customers in Houston and San
Antonio, Texas.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The consolidated financial statements include the financial statements of
Hallmark Air Conditioning, Inc. (Hallmark) and its wholly-owned subsidiary,
Jerry Albert Air Conditioning, Inc. (Jerry Albert). All significant
intercompany balances and transactions have been eliminated in consolidation.
 
 Interim Financial Information
 
  The interim consolidated financial statements for the three months ended May
31, 1996 are unaudited, and certain information and footnote disclosures,
normally included in financial statements prepared in accordance with
generally accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the consolidated interim financial statements, have
been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the
consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Revenue Recognition
 
  Revenue is recognized upon completion of service. Revenues on service and
maintenance contracts are recognized over the life of the contract.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest and taxes were $32,261 and
$54,300, respectively, for the year ended February 28, 1997, and $28,310 and
$-0-, respectively, for the three months ended May 31, 1997.
 
 Inventories
 
  Inventories consist primarily of purchased materials and supplies. The
Company uses the first-in, first-out (FIFO) cost method to value its
inventories.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the estimated useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated useful life of the asset.
 
 
                                     F-131
<PAGE>
 
                HALLMARK AIR CONDITIONING, INC. AND SUBSIDIARY
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statement of operations.
 
 Income Taxes
 
  The Company uses the asset and liability method to account for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
 New Accounting Pronouncement
 
  Effective March 1, 1996, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.

</TABLE>
 
  During the year ended February 28, 1997 and the three months ended May 31,
1997, the Company acquired $74,506 and $31,387, respectively, of property and
equipment in exchange for obligations under capital leases.
 
5. GOODWILL AND OTHER ASSETS
 
  Goodwill represents the excess of the aggregate purchase price over the fair
value of net assets acquired and is amortized on a straight-line basis over a
period of 40 years. The Company assesses the recoverability of this intangible
asset by determining whether the amortization of the goodwill balance over its
remaining life can be recovered through undiscounted future operating cash
flows of the acquired operation. The amount of goodwill impairment, if any, is
measured based on projected discounted future operating cash flows compared to
the carrying value of goodwill. The assessment of the recoverability of
goodwill will be impacted if estimated future operating cash flows are not
achieved.
 
  Other assets include a covenant not to compete related to the acquisition of
Jerry Albert. The covenant not to compete is being amortized on a straight-
line basis over the life of the covenant, which is five years.
 
6. SHORT- AND LONG-TERM DEBT
 
  Short- and long-term debt consists of the following:

contingent rentals based on mileage. Rental expense for these operating leases
during the year ended February 28, 1997 and the three months ended May 31,
1997 was approximately $18,600 and $5,000, respectively.

financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on

standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence

also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Sibley Services,
Incorporated as of October 31, 1996 and June 30, 1997, and the results of its

                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION
 
  Sibley Services, Incorporated (the Company) is primarily engaged in the
installation and servicing of heating and air conditioning systems for
commercial and industrial customers in Memphis, Tennessee and the surrounding
area.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the eight months ended June 30, 1996
are unaudited, and certain information and footnote disclosures, normally
included in financial statements prepared in accordance with generally
accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the interim financial statements, have been
included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest and taxes were $26,004 and
$130,791, respectively, for the year ended October 31, 1996. Cash payments for
interest and taxes were $10,589 and $9,500, respectively, for the eight months
ended June 30, 1997.
 
 Inventories
 
  Inventories consist primarily of purchased materials. The inventory is
valued at the lower of cost or market, with cost determined on a first-in,
first-out (FIFO) basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated life of the asset.

                         SIBLEY SERVICES, INCORPORATED
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.
 
 Income Taxes
 
  The Company uses the asset and liability method to account for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
 New Accounting Pronouncement
 
  Effective November 1, 1995, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Southeast Mechanical Service, Inc. (the Company) is primarily engaged in the
servicing of commercial heating and air conditioning systems in Southeast
Florida including Broward, Dade and Palm Beach Counties.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the six months ended June 30, 1996 and
as of September 30, 1997 and for the nine months ended September 30, 1996 and
1997, are unaudited, and certain information and footnote disclosures,
normally included in financial statements prepared in accordance with
generally accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the interim financial statements, have been
included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid debt instruments with a maturity of three months or less to be
cash equivalents. Cash payments for interest were $16,406 and $27,839 for the
year ended December 31, 1996 and the six months ended June 30, 1997,
respectively.
 
 Inventories
 
  Inventories consist of parts and supplies used in the service portion of the
Company's operation. The inventory is valued at the lower of cost or market,
with cost determined on a first-in, first-out (FIFO) basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated useful life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated.

                      SOUTHEAST MECHANICAL SERVICE, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
Upon retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.
 
 Warranty Costs
 
  The Company warrants labor for the first year after installation on new air
conditioning and heating units. The Company generally warrants labor for 30
days after servicing of existing air conditioning and heating units. A reserve
for warranty costs is recorded upon completion of installation or service.
 
 Income Taxes
 
  The shareholders of the Company have elected to be taxed for federal tax
purposes as an S Corporation whereby the shareholders' respective equitable
shares in the taxable income of the Company are reportable on their individual
tax returns. The Company will make distributions to the shareholders each year
at least in amounts necessary to pay personal income taxes payable on the
Company's taxable income.
 
 New Accounting Pronouncement
 
  Effective January 1, 1996, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.
 
3. COSTS AND ESTIMATED EARNINGS ON UNCOMPLETED CONTRACTS

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Willis Refrigeration, Air Conditioning & Heating, Inc. (the Company) is
primarily engaged in the installation and servicing of heating and air
conditioning systems for residential customers in Ohio and northern Kentucky.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the three months ended June 30, 1996
and the six months ended September 30, 1997 and September 30, 1996, are
unaudited, and certain information and footnote disclosures, normally included
in financial statements prepared in accordance with generally accepted
accounting principles, have been omitted. In the opinion of management, all
adjustments, consisting only of normal recurring adjustments, necessary to
fairly present the financial position, results of operations and cash flows
with respect to the interim financial statements, have been included. The
results of operations for the interim periods are not necessarily indicative
of the results for the entire fiscal year.
 
 Use of Estimates
 
  Management uses estimates and assumptions in preparing the financial
statements in accordance with generally accepted accounting principles. Those
estimates and assumptions affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities, and the
reported revenues and expenses.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from new construction sales are recognized on the
percentage of completion basis with seventy percent of the revenue recognized
at initial installation of new units and thirty percent recognized at the
final stage of installation when the residential building is nearing
completion. Material, equipment and labor costs are estimated for each job and
are recognized on the same percentage method.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest were $25,379 and $2,131 for
the year ended March 31, 1997 and the three months ended June 30, 1997.
 
 Inventories
 
  Inventories consist primarily of parts and supplies used in both the service
and construction portions of the Company's operation. Inventory is stated at
the lower of cost or market.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated.

            WILLIS REFRIGERATION, AIR CONDITIONING & HEATING, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
Upon retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.
 
 Marketable Securities
 
  The Company accounts for marketable securities in accordance with SFAS No.
115, Accounting for Certain Investments in Debt and Equity Securities. All of
the Company's marketable securities (all of which are equity securities) have
been classified as available for sale with unrealized gains or losses recorded
as a separate component of shareholders' equity. As of March 31, 1997 and June
30, 1997 the amortized cost of the marketable securities was $12,900.
 
 Warranty Costs
 
  The Company warrants labor for the first year after installation on new air
conditioning and heating units. The Company generally warrants labor for 90
days after servicing of existing air conditioning and heating units. A reserve
for warranty costs is recorded upon completion of installation or services.
 
 Income Taxes
 
  The Company accounts for income taxes using the asset and liability method.
Under the asset and liability method, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities
and their respective tax bases. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.
 
 New Accounting Pronouncement
 
  Effective April 1, 1996, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.

The Board of Directors
Yale Incorporated
 
  We have audited the accompanying balance sheets of Yale, Inc. as of
September 30, 1996 and June 30, 1997, and the related statements of
operations, shareholders' equity and cash flows for the year ended September
30, 1996 and the nine months ended June 30, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Yale Incorporated as of
September 30, 1996 and June 30, 1997, and the results of its operations and
its cash flows for the year ended September 30, 1996 and the nine months ended
June 30, 1997 in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Yale Incorporated (the Company) is primarily engaged in the installation and
servicing of heating and air conditioning systems for commercial and
industrial customers in the state of Minnesota.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the nine months ended June 30, 1996 are
unaudited, and certain information and footnote disclosures, normally included
in financial statements prepared in accordance with generally accepted
accounting principles, have been omitted. In the opinion of management, all
adjustments, consisting only of normal recurring adjustments, necessary to
fairly present the financial position, results of operations and cash flows
with respect to the interim financial statements, have been included. The
results of operations for the interim periods are not necessarily indicative
of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting year. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid debt instruments with a maturity of three months or less to be
cash equivalents. Cash payments for interest were $37,791 and $24,350 for the
year ended September 30, 1996 and the nine months ended June 30, 1997,
respectively.
 
 Inventories
 
  Inventories consist of parts and supplies used in both the service and the
construction portions of the Company's operation. The inventory is valued at
the lower of cost or market, with cost determined on a first-in, first-out
(FIFO) basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated useful life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated.
 
                                     F-172
<PAGE>
 
                               YALE INCORPORATED
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
Upon retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.
 
 Warranty Costs
 
  The Company warrants labor for the first year after installation on new air
conditioning and heating units. The Company generally warrants labor for 90
days after servicing of existing air conditioning and heating units. A reserve
for warranty costs is recorded upon completion of installation or service.
 
 Income Taxes
 
  The shareholders of the Company have elected to be taxed for federal and
Minnesota tax purposes as an S Corporation whereby the shareholders'
respective equitable shares in the taxable income of the Company are
reportable on their individual tax returns. The Company has made distributions
to the shareholders each year at least in amounts necessary to pay personal
income taxes payable on the Company's taxable income.
 
 New Accounting Pronouncement
 
  Effective October 1, 1995, the Company adopted SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of. Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect
on the financial position or results of operations of the Company.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Hungerford Mechanical Corporation (the Company) operates as a mechanical
contractor specializing in the installation and servicing of plumbing,
sprinkler, heating and air conditioning systems. The Company markets its
services within the Richmond, Virginia metropolitan area. Revenues are
generated primarily from individual contracts.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 USE OF ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 REVENUE AND COST RECOGNITION
 
  Revenues from fixed-price and modified fixed-price construction contracts
are recognized on the percentage of completion method. The completed
percentage is measured by the percentage of cost incurred to date as compared
to the estimated total cost for each contract.
 
  Contract costs include all direct material and labor costs and those
indirect costs related to contract performance, such as labor, supplies,
tools, repairs and depreciation. Selling, general and administrative costs are
charged to expense as incurred. Provisions for estimated losses on uncompleted
contracts are made in the period in which such losses are determined. Changes
in job performance, job conditions, and estimated profitability may result in
revisions to costs and revenues and are recognized in the period in which the
revisions are determined.
 
 INVENTORIES
 
  Inventories consist of parts and supplies used mainly in the service portion
of the Company's operation. The inventory is valued at the lower of cost or
market, with cost determined on a first-in, first-out (FIFO) basis.
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statement of operations.
 
 CASH VALUE OF LIFE INSURANCE
 
  Cash value of life insurance represents the cash value of life insurance
policies for key employees of the Company net of loans taken against the
policies.

                         NOTES TO FINANCIAL STATEMENTS
 
(1) BUSINESS AND ORGANIZATION
 
  Mechanical Interiors, Inc. (the Company) is primarily engaged in the
installation and servicing of heating and air conditioning systems for
commercial customers in the areas in and around Dallas and Austin, Texas.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Cash and Cash Equivalents
 
  For purposes of the statement of cash flows, the Company considers all
highly liquid debt instruments with an original maturity of three months or
less to be cash equivalents. Cash payments for interest and income taxes were
$73,067 and $222,640, respectively, for the year ended December 31, 1997.
 
 Inventories
 
  Inventories consist of parts and supplies used mainly in the service portion
of the Company's operation. The inventory is valued at the lower of cost or
market, with cost determined on a first-in, first-out (FIFO) basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statement of operations.
 
  The Company reviews the carrying value of its property and equipment for
impairment. Accordingly, in the event that facts and circumstances indicate
that property and equipment may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine if a write-down to market value is necessary. The
Company recorded no impairment of its property and equipment during the year
ended December 31, 1997.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Warranty Costs
 
  The Company warrants labor for the first year after installation on new air
conditioning and heating units. The Company generally warrants labor for 90
days after servicing of existing air conditioning and heating units. A reserve
for warranty costs is recorded upon completion of installation or service.
 
 Income Taxes
 
  The Company accounts for income taxes using the asset and liability method.
Under the asset and liability method, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities
and their respective tax bases. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Premex, Inc. is the holding company of Commercial Air, Power and Cable, Inc.
(Commercial Air), a wholly-owned subsidiary, (collectively referred to herein
as the Company). Commercial Air provides retrofit renovations, replacement
equipment installations, service and maintenance for building automation
systems, electrical distribution systems, distributed data processing systems,
communication networks and complex building mechanical systems. All this work
is either performed under a fixed price, modified fixed price, cost-plus-fee,
or a time and material contract. Commercial Air's market area is the
metropolitan Baltimore/Washington, D.C. area.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The consolidated financial statements include the financial statements of
Premex, Inc. and its wholly owned subsidiary Commercial Air. All significant
intercompany balances and transactions have been eliminated in consolidation.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue and Cost Recognition
 
  Revenues from fixed-price and modified fixed-price and cost-plus-fee
construction contracts are recognized on the percentage of completion method.
The completed percentage is measured by the percentage of cost incurred to
date as compared to the estimated total cost for each contract. Revenues from
service contracts are recognized ratably over the term of the service
contract. Revenue from time and material service projects are recognized at
the completion of the project.
 
  Contract costs include all direct material and labor costs and those
indirect costs related to contract performance, such as labor, supplies,
tools, repairs and depreciation. Selling, general and administrative costs are
charged to expense as incurred. Provisions for estimated losses on uncompleted
contracts are made in the period in which such losses are determined. Changes
in job performance, job conditions, and estimated profitability may result in
revisions to costs and revenues and are recognized in the period in which the
revisions are determined.
 
  Revenues for one customer amounted to 12.6% of revenues during the year
ended March 31, 1998.
 
 
 Inventories
 
  Inventories consist of parts and supplies used mainly in the service portion
of the Company's operation. The inventory is valued at the lower of cost or
market, with cost determined using the weighted average method of valuation.
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statements of operations.

                          PREMEX, INC. AND SUBSIDIARY
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company leases vehicles used in its operations under leases which have
been capitalized. The vehicles are being depreciated using the straight-line
method over their estimated useful lives, which is approximately 5 years.
Leases not meeting the criteria for capital leases are classified as operating
leases and are charged to rent equipment expense as incurred.
 
 Income Taxes
 
  The Company uses the asset and liability method to account for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
 Supplemental Disclosure of Cash Flow Information
 
  Cash payments for interest and income taxes were $152,297 and $138,967,
respectively, for the year ended March 31, 1998. During the year ended March
31, 1998, the Company acquired vehicles and computer equipment under capital
leases amounting to $336,885.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  Barr Electric Corp. (the Company), an Illinois corporation, is a provider of
electrical contracting services consisting of installation, service and
maintenance of electrical systems primarily in the Chicago, Illinois area.
This work is performed under fixed price contracts subject to modifications
based on approved change orders or under time and material contracts.
 
2. SUMMARY OF SIGNIFICANT POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the three months ended March 31, 1997
and 1998 are unaudited, and certain information and footnote disclosures,
normally included in financial statements prepared in accordance with
generally accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the interim financial statements, have been
included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue and Cost Recognition
 
  Revenues from fixed price contracts are recognized on the percentage of
completion method. The completed percentage is measured by the percentage of
cost incurred to date as compared to the estimated total cost for each
contract, including work for approved change orders. Revenue from time and
material contracts is recognized at the completion of the job.
 
  Contract costs include all direct material, subcontract and labor costs and
a provision for indirect costs such as indirect labor, payroll taxes, tools,
equipment rental, permits, union welfare payments, truck expense and
depreciation. Selling, general and administrative costs are charged to expense
as incurred. Provisions for estimated losses on uncompleted contracts are made
in the period in which such losses are determined. Changes in job performance,
job conditions, and estimated profitability may result in revisions to costs
and revenues and are recognized in the period in which the revisions are
determined.
 
  The Company's largest three customers accounted for 86% of total revenues
for the year ended December 31, 1997.
 
 Cash and cash equivalents
 
  The Company considers investments in money market accounts and certificates
of deposits purchased with an original maturity of three months or less to be
cash equivalents.
 
 Inventories
 
  Inventories consist of parts and supplies used in the Company's operations.
The inventory is valued at the lower of cost or market, with cost determined
using the weighted average method of valuation.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Machinery and Equipment
 
  Machinery and equipment are stated at cost. Depreciation is computed using
the straight-line method over the useful lives of the assets. Expenditures for
major renewals and improvements, which extend the useful lives of existing
equipment, are capitalized and depreciated. Expenditures for repairs and
maintenance are charged to expense when incurred. Upon retirement or
disposition of property and equipment, the cost and related accumulated
depreciation are removed from the accounts and any resulting gain or loss is
recognized in the statements of operations.
 
 Income Taxes
 
  The Company has elected to be taxed under the provisions of Subchapter S of
the Internal Revenue Code. Under those provisions, the Company does not pay
corporate income taxes on its taxable income. Instead, the shareholders are
liable for individual income taxes on their respective shares of the Company's
net operating income in their individual income tax returns. Therefore, no
income tax expense appears on these financial statements.
 
3. PROFIT SHARING PLAN
 
  The Company has a Profit-Sharing Plan for eligible non-union employees. All
contributions to the plan are 100% vested in the employees' accounts and are
made at the discretion of management. The Company's contribution to the plan
was $91,711 in 1997.
 
4. LEASES
 
  The Company operates from a leased facility under an operating lease that
expires March 14, 2000. The annual rental amount under the current lease
agreement is $55,000.
 
  Net future minimum rental payments required under operating leases as of
December 31, 1997 are as follows:

  In addition to these minimum rentals, the Company agrees to pay their

over the base year period of January 1, 1995 to December 31, 1995.

                                                                       ========
</TABLE>
 
  Fixed assets generally are depreciated over useful lives of 5-7 years.
 
7. EMPLOYEE BENEFIT PLANS
 
  The Company makes contributions to a union-administered benefit fund which
covers a majority of the Company's employees. For the year ended December 31,
1997, the participant costs charged to operations were approximately $0.9
million. Governmental regulations impose certain requirements relative to
multi-employer plans. In the event of a plan's termination or employer
withdrawal, the Company may be liable for a portion of the plans' unfunded
vested benefits, if any. The Company has not yet received information from the
plans' administrators to determine its share of any unfunded vested benefits.
The Company does not anticipate withdrawal from the plans, nor is the Company
aware of any expected plan terminations.
 
8. COMMITMENTS AND CONTINGENCIES
 
  The Company is involved in various claims and legal actions arising in the
ordinary course of business. In the opinion of management, the ultimate
disposition of these matters will not have a material adverse effect on the
Company's financial position, results of operations or liquidity.
 
  Many computer software programs, as well as certain hardware and equipment
containing date sensitive data, were structured to utilize a two-digit date
field meaning that they may not be able to properly recognize dates in the
year 2000 and later. This could result in significant system and equipment
failures. The Company has assessed its current software programs and
determined that the Company's software programs will need to

be replaced. It is the Company's intentions to replace affected software
before the year 2000. Assessments and cost estimates are being conducted
currently by Group Maintenance America Corp. which acquired the Company as
discussed in note 9.
 
9. SUBSEQUENT EVENT
 
  In March 1998, the Company entered into an agreement whereby Group
Maintenance America Corp. (GroupMAC) has acquired all of the outstanding
shares of the Company for a combination of cash and common stock of GroupMAC.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Atlantic Industrial Constructors, Inc.
 
  We have audited the accompanying combined balance sheets of Atlantic
Industrial Constructors, Inc. and Affiliates (the Company) as of December 31,
1996 and 1997, and the related combined statements of operations,
shareholders' equity and cash flows for each of the years in the three-year
period ended December 31, 1997. These combined financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of Atlantic
Industrial Constructors, Inc. and Affiliates as of December 31, 1996 and 1997,
and the results of their operations and their cash flows for each of the years
in the three-year period ended December 31, 1997 in conformity with generally
accepted accounting principles.

             ATLANTIC INDUSTRIAL CONSTRUCTORS, INC. AND AFFILIATES
 
                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  The combined financial statements included herein provide the financial
position, results of operations and cash flows, after elimination of material
inter-company balances, for Atlantic Industrial Constructors, Inc. (AIC),
Atlantic Industrial Maintenance, Inc. (AIM) and Atlantic Industrial Leasing
Corporation (AILC), (collectively, the Company). Historically, AIC, AIM and
AILC have been under common ownership and management and AIM and AILC have
been operated essentially as subsidiaries of AIC. The Company provides
contract services including the process pipe fabrication, structural steel
fabrication and erection, engineered heavy lift and transportation, mechanical
heavy lift and transportation, jetway refurbishing and mechanical equipment
installation to large industrial customers primarily in the Virginia and North
Carolina areas. This work is performed under fixed price contracts subject to
modifications based on approved change orders or under time and material
contracts. The Company also engages in industrial plant maintenance through
its service division under time and material and fixed price contracts.
 
2. SUMMARY OF SIGNIFICANT POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the three months ended March 31, 1997
and 1998 are unaudited, and certain information and footnote disclosures,
normally included in financial statements prepared in accordance with
generally accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the interim financial statements, have been
included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue and Cost Recognition
 
  Revenues from fixed price contracts are recognized on the percentage of
completion method. The completed percentage is measured by the percentage of
cost incurred to date as compared to the estimated total cost for each
contract, including work for approved change orders. Revenue from time and
material contracts is accrued at the end of each month based on chargeable
costs incurred through month end.
 
  Contract costs include all direct material, subcontract and labor costs and
a provision for indirect costs such as indirect labor, payroll taxes, tools,
equipment rental, permits, union welfare payments, truck expense and
depreciation. Selling, general and administrative costs are charged to expense
as incurred. Provisions for estimated losses on uncompleted contracts are made
in the period in which such losses are determined. Changes in job performance,
job conditions, and estimated profitability may result in revisions to costs
and revenues and are recognized in the period in which the revisions are
determined.

                                                          ========== ==========
</TABLE>
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the useful lives of the assets. Expenditures for
major renewals and improvements, which extend the useful lives of existing
equipment, are capitalized and depreciated. The estimated useful lives of
assets are 5 to 7 years.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Upon retirement or disposition of property and equipment, the cost
and related accumulated depreciation are removed from the accounts and any
resulting gain or loss is recognized in the statements of operations.
 
 Income Taxes
 
  AIC and AIM have elected to be taxed under the provisions of Subchapter S of
the Internal Revenue Code. Under those provisions, AIC and AIM do not pay
corporate income taxes on their taxable income. Instead, the stockholders are
liable for individual income taxes on their respective shares of AIC's and
AIM's net operating income in their individual income tax returns. Therefore,
no income tax provision or liability appears on these financial statements
with respect to the earnings of AIC and AIM. AILC is taxed under the
provisions of Subchapter C of the Internal Revenue Code but due to the
relatively small size of this entity the related income taxes are not material
to the combined financial statements.
 
 Credit Risk
 
  Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash, accounts receivable
and costs and estimated earnings in excess of billings on uncompleted
contracts.

<PAGE>
 
             ATLANTIC INDUSTRIAL CONSTRUCTORS, INC. AND AFFILIATES
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Company maintains its cash balances in one financial institution. The
balances are insured by the Federal Deposit Insurance Corporation up to
$100,000. The Company generally has funds deposited in excess of $100,000.
 
  Accounts receivable and costs and estimated earnings in excess of billings
on uncompleted contracts result primarily from contracts with customers
principally in the Eastern United States. Credit is extended to customers
after an evaluation for credit worthiness; however, the Company does not
require collateral or other security from customers.
 
3. RETIREMENT PLANS
 
  The Company has a profit-sharing retirement plan and a money purchase
pension plan. The plans cover substantially all full-time employees who have
completed at least one year of service and are not covered under separate
collective bargaining agreements. For the profit sharing plan, there is no
specific contribution formula, and the Board of Directors sets the Company's
contributions annually, subject to limitations imposed by the Internal Revenue
Code. For the money purchase plan, the Company contributes 5% of participants'
eligible compensation. For the years ended December 31, 1995, 1996 and 1997,
the Company's contributions aggregated $215,469, $287,147 and $349,701,
respectively.
 
  The Company makes contributions to a union-administered benefit fund which
covers the majority of the Company's employees. For the years ended December
31, 1995, 1996 and 1997, the participant costs charged to operations were
approximately $0.8 million, $1.0 million and $1.7 million, respectively.
Governmental regulations impose certain requirements relative to multi-
employer plans. In the event of a plan's termination or employer withdrawal,
the Company may be liable for a portion of the plans' unfunded vested
benefits, if any. The Company has not yet received information from the plans'
administrators to determine its share of any unfunded vested benefits. The
Company does not anticipate withdrawal from the plans, nor is the Company
aware of any expected plan terminations.
 
4. LEASES
 
  The Company leases its office and shop facility, on a month-to-month basis,
from Atlantic Leasing Associates, a partnership whose partners are the
Company's shareholders. Under provisions of the lease, the Company is
responsible for taxes, insurance and utilities. Rent expense under this lease
was $58,243, $106,292 and $186,323 for the years ended December 31, 1995, 1996
and 1997, respectively.
 
5. COSTS AND ESTIMATED EARNINGS ON UNCOMPLETED CONTRACTS
 
  A summary of the status of uncompleted contracts as of December 31, 1996 and
1997 is as follows:

7. NOTES PAYABLE
 
  The notes incur interest at 5 3/5% with interest payable annually at
December 31. The notes are due based upon the Company's ability to pay.
 
8. COMMITMENTS AND CONTINGENCIES
 
  The Company is involved in various claims and legal actions arising in the
ordinary course of business. In the opinion of management, the ultimate
disposition of these matters will not have a material adverse effect on the
Company's financial position, results of operations or liquidity.
 
9. SHAREHOLDERS' EQUITY
 
  Common stock par value and shares authorized, issued and outstanding for
AIC, AIM and AILC, respectively, are as follows:
 
<TABLE>

                                                              AIC    AIM  AILC

      <S>                                                    <C>    <C>   <C>
      Par Value ($ per share)............................... $10.00 $1.00 $1.00
      Shares authorized..................................... 10,000 5,000 5,000
      Shares issued and outstanding.........................    200   200   200
</TABLE>
 
  By written agreement, AIC is obligated to purchase the common stock of any
shareholder upon his death or termination of employment with the Company. The
price is determined by formula in the agreement. The Company is a party to
life insurance contracts with combined death benefits of $3.0 million to fund
these obligations.
 
10. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  Methods and assumptions used to estimate the fair value of each class of
financial instruments are as follows:
 
    (a) Cash and cash equivalents, trade accounts receivable, and payables--
  The carrying amounts approximate fair value because of the short maturity
  of these instruments.
 
    (b) Notes payable to shareholders--The carrying amount approximates fair
  value because the interest rate approximates the market rate.

    (c) Cash surrender value of life insurance policy is stated at its cash
  value as determined by the insurance carrier, which approximates fair
  value.
 
11. SUBSEQUENT EVENT
 
  On June 12, 1998, the Company entered into agreements whereby Group
Maintenance America Corp. (GroupMAC) acquired all of the outstanding shares of
the Company for a combination of cash and common stock of GroupMAC.

                         NOTES TO FINANCIAL STATEMENTS
 
 (ALL INFORMATION WITH RESPECT TO THE INTERIM PERIODS ENDED JUNE 30, 1997 AND
                              1998 IS UNAUDITED)
 
 
1. BUSINESS AND ORGANIZATION
 
  Clark Converse Electric Service, Inc. (the "Company") is an electrical
contractor involved in the construction and renovation on projects primarily
for general contractors and other companies in northwest Ohio and southeast
Michigan. The work is typically performed under fixed-price and cost-plus
contracts, or time-and-material purchase requisitions. The length of the
Company's contracts vary, but is typically less than one year.
 
2. SUMMARY OF SIGNIFICANT POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the six months ended June 30, 1997 and
1998 and as of June 30, 1998 are unaudited, and certain information and
footnote disclosures, normally included in financial statements prepared in
accordance with generally accepted accounting principles, have been omitted.
In the opinion of management, all adjustments, consisting only of normal
recurring adjustments, necessary to fairly present the financial position,
results of operations and cash flows with respect to the interim financial
statements, have been included. The results of operations for the interim
periods are not necessarily indicative of the results for the entire fiscal
year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue and Cost Recognition
 
  Revenues from fixed price contracts are recognized on the percentage of
completion method. The completed percentage is measured by the percentage of
cost incurred to date as compared to the estimated total cost for each
contract, including work for approved change orders. Revenue from cost-plus-
fee contracts are recognized on the basis of costs incurred during the period
plus the fee earned, measured by the cost-to-cost method. Revenue from time
and material contracts is accrued at the end of each month based on chargeable
costs incurred through month end. Time and material contracts are billed for
the number of man-hours and costs incurred.
 
  Contract costs include all direct material, subcontract and labor costs and
a provision for indirect costs such as indirect labor and equipment costs.
Selling, general and administrative costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted contracts are made in the
period in which such losses are determined. Changes in job performance, job
conditions, and estimated profitability, including those arising from contract
penalty provisions, and final contract settlements may result in revisions to
costs and revenues and are recognized in the period in which the revisions are
determined.
 
 Cash and Cash Equivalents
 
  For purposes of the statement of cash flows, the Company considers
investments in money market accounts and certificate of deposits purchased
with an original maturity of three months or less to be cash equivalents. Cash
payments for taxes were $19,881, $10,600 and $19,606 for the year ended
December 31, 1997 and six months ended June 30, 1997 and 1998, respectively.

 Accounts Receivable
 
  Accounts receivable-trade consists of the following at December 31, 1997:
 
<TABLE>
      <S>                                                               <C>
      Accounts receivable--billed...................................... $877,374
      Retainage receivables............................................  105,599
                                                                        --------
                                                                        $982,973
                                                                        ========
</TABLE>
 
  The Company considers accounts receivable to be fully collectible;
accordingly, no allowance for doubtful accounts is required.
 
 Income Taxes
 
  The shareholder of the Company has elected to be taxed for federal and state
tax purposes as an S Corporation whereby the shareholder's respective
equitable share in the taxable income of the Company is reportable on his
individual tax return. The Company has made distributions to the shareholder
each year at least in the amounts necessary to pay personal income taxes
payable on the Company's taxable income. The Company is subject to local
income taxes. As of December 31, 1997, deferred income taxes are
insignificant.
 
 Credit Risk
 
  Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash, accounts receivable
and costs and estimated earnings in excess of billings on uncompleted
contracts.
 
  The Company maintains its cash balances in one financial institution. The
balances are insured by the Federal Deposit Insurance Corporation up to
$100,000. The Company generally has funds deposited in excess of $100,000.
 
  Accounts receivable and costs and estimated earnings in excess of billings
on uncompleted contracts result primarily from contracts with customers
principally in the Company's service area in northwest Ohio and southeast
Michigan. Credit is extended to customers after an evaluation for credit
worthiness; however, the Company does not require collateral or other security
from customers.
 
  The Company's three largest customers accounted for 22%, 19% and 13%,
respectively, of total revenues for the year ended December 31, 1997.
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the useful lives of the assets. Expenditures for
major renewals and improvements, which extend the useful lives of existing
equipment, are capitalized and depreciated. The estimated useful lives of
assets by class are as follows:
 
<TABLE>
      <S>                                                             <C>
      Machinery and equipment........................................ 5-10 years
      Vehicles.......................................................    5 years
      Office equipment...............................................  5-7 years

                     CLARK CONVERSE ELECTRIC SERVICE, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Upon retirement or disposition of property and equipment, the cost
and related accumulated depreciation are removed from the accounts and any
resulting gain or loss is recognized in the statements of operations.
 
3. EMPLOYEE BENEFIT PLANS
 
  The Company maintains a salary reduction 401(k) plan covering all employees
meeting certain age and service requirements. Annual contributions are
committed to an independent trustee to be held for the exclusive benefit of
the employees. Annual contributions to the plan by the Company include a
matching contribution, up to 4%, for eligible compensation of participants
electing voluntary salary reduction deferrals and a discretionary amount
determined each year by the Board of Directors of the Company. The Company's
contribution expense amounted to $10,399 for the year ended December 31, 1997.
 
4. LEASES
 
  The Company leases its offices and warehouse space from an affiliated
partnership consisting of its shareholder and another tenant. The Company's
lease is for a one-year term and management intends and has the ability to
annually renew the lease. The current lease requires a monthly rental of
$5,658 and rent expense was $66,816 for the year ended December 31, 1997.
 
5. COSTS AND ESTIMATED EARNINGS ON UNCOMPLETED CONTRACTS
 
  A summary of the status of uncompleted contracts as of December 31, 1997 is

7. CONTINGENCIES
 
  In the normal course of business the Company experiences various claims and
lawsuits from third parties. During 1997, the Company was named a defendant in
a claim from a former employee on a Workers' Compensation dispute. The Company
received a favorable ruling from the Ohio Bureau of Workers' Compensation and
does not believe the ultimate resolution of this matter will have a material
adverse effect on results of operations, financial condition or liquidity.
 
8. BANK LINE OF CREDIT
 
  The Company has a revolving line of credit with a bank in the amount of
$1,000,000 with no amount outstanding at December 31, 1997. The credit
agreement provided for revolving credit through March 1998 and is secured by
accounts receivable and the guarantee of the sole stockholder/president of the
Company. Interest is computed at the bank's prime rate (8.5% at December 31,
1997).
 
9. SUBSEQUENT EVENT
 
  Effective August 28, 1998, Group Maintenance America Corp. (GroupMAC)
acquired all of the outstanding shares of the Company for a combination of
cash and common stock of GroupMAC.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION
 
  HPS Plumbing Services, Inc. (the "Company") provides plumbing and piping
services in California and Nevada, primarily for governmental entities and
general contractors. This work is performed under fixed price contracts
subject to modification based on approved change orders, cost-plus-fee
contracts and time and material contracts. The Company grants credit on terms
it establishes for individual customers in these areas.
 
2. SUMMARY OF SIGNIFICANT POLICIES
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue and Cost Recognition
 
  Revenues from fixed price contracts are recognized on the percentage of
completion method. The completed percentage is measured by the percentage of
cost incurred to date as compared to the estimated total cost for each
contract, including work for approved change orders. Revenue from cost-plus-
fee contracts are recognized on the basis of costs incurred during the period
plus the fee earned, measured by the cost-to-cost method. Revenue from time
and material contracts is accrued at the end of each month based on chargeable
costs incurred through month end. Time and material contracts are billed for
the number of man hours and costs incurred.
 
  Contract costs include all direct material, subcontract and labor costs and
a provision for indirect costs such as indirect labor and equipment costs.
Selling, general and administrative costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted contracts are made in the
period in which such losses are determined. Changes in job performance, job
conditions, and estimated profitability, including those arising from contract
penalty provisions, and final contract settlements may result in revisions to
costs and revenues and are recognized in the period in which the revisions are
determined.
 
 Cash and cash equivalents
 
  For purposes of the statement of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest and taxes were $38,800 and
$518,835, respectively, for the nine months ended March 31, 1998.
 
 Accounts Receivable
 
  Accounts receivable consists of the following at March 31, 1998:

 Inventories
 
  Inventories consist of parts and supplies for general use and items for
specific jobs. Inventories are stated at lower of cost or market. Cost is
determined using the first-in, first-out method.

 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the useful lives of the assets. Expenditures for
major renewals and improvements, which extend the useful lives of existing
equipment, are capitalized and depreciated. The estimated useful lives of
assets are as follows:

      Furniture and fixtures..............................................  5-7
      Computer equipment..................................................  3-5
      Leasehold improvements.............................................. 5-10
</TABLE>
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Upon retirement or disposition of property and equipment, the cost
and related accumulated depreciation are removed from the accounts and any
resulting gain or loss is recognized in the statements of operations.
 
 Income Taxes
 
  The Company uses the asset and liability method to account for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

the equipment agreement has an annual rental of $25,800. Rent expense for the
lease of office and warehouse space during the nine months ended March 31,
1998 was $58,520. The primary term of the building lease is 5 years with 5
options to extend of one year each. The equipment lease agreement is on a
monthly basis.
 
  The building lease agreement provides that an adjacent tenant may move into
the Company's space during a period beginning on October 1, 2001 and ending on
October 1, 2003. If this option is exercised, the Company would be forced to
move and would be reimbursed for its costs by the lessor in the amount of
$350,928. This amount decreases by $14,622 per month, beginning November 1,
2001.
 
  In addition, the Company leases various trucks, trailers and office
equipment with lease terms expiring through 2002. The rental expense recorded
under operating leases for equipment for the nine months ended March 31, 1998
was $94,259.
 
  Future minimum lease payments under noncancelable operating leases (with
initial or remaining lease terms in excess of one year) as of March 31, 1998
are as follows:

  Management believes that it is more likely than not that the Company will
realize the benefits of the deferred income tax assets recorded at March 31,
1998.
 
9. EMPLOYEE BENEFIT PLANS
 
  The Company has a defined contribution retirement plan covering employees
who meet eligibility requirements set forth in the plan. Contributions to the
plan are based on specific project rates, contributed for the benefit of
individual employees for work performed on public works projects. Employees
are vested 100% in the Company's contributions. Contributions to the plan for
the nine months ended March 31, 1998 were $286,959.
 
10. SALES TO SIGNIFICANT CUSTOMERS
 
  During the nine months ended March 31, 1998, sales to three customers
accounted for 15%, 13% and 12%, respectively, of the Company's revenues.
 
11. COMMITMENTS AND CONTINGENCIES
 
  The Company is involved in various claims and legal actions arising in the
ordinary course of business. In the opinion of management, the ultimate
disposition of these matters will not have a material adverse effect on the
Company's financial position, results of operations or liquidity.
 
12. FINANCIAL INSTRUMENTS
 
  The Company's financial instruments include cash and cash equivalents and
short- and long-term debt. The Company believes that the carrying value of
these instruments on the accompanying balance sheet approximates their fair
value. Additionally, amounts due from related parties and employees represent
financial instruments, the fair value of which it is impracticable to
estimate.
 
13. SUBSEQUENT EVENT
 
  Effective April 1, 1998 Group Maintenance America Corp. (GroupMAC) acquired
all of the outstanding shares of the Company for a combination of cash and
common stock of GroupMAC.

                         NOTES TO FINANCIAL STATEMENTS
 
 
1. BUSINESS AND ORGANIZATION
 
  Ray and Claude Goodwin, Inc., doing business as Ray's Plumbing Contractors,
Inc., (the "Company") provides plumbing and piping services in the
Jacksonville, Florida area, primarily for governmental entities and general
contractors. This work is performed under fixed price contracts subject to
modification based on approved change orders and time and material contracts.
The Company grants credit on terms it establishes for individual customers in
these areas.
 
2. SUMMARY OF SIGNIFICANT POLICIES
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue and Cost Recognition
 
  Revenues from fixed price contracts are recognized on the percentage of
completion method. The completed percentage is measured by the percentage of
cost incurred to date as compared to the estimated total cost for each
contract, including work for approved change orders. Revenue from time and
material contracts is accrued at the end of each month based on chargeable
costs incurred through month end. Time and material contracts are billed for
the number of man hours and costs incurred.
 
  Contract costs include all direct material, subcontract and labor costs and
a provision for indirect costs such as indirect labor and equipment costs.
Selling, general and administrative costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted contracts are made in the
period in which such losses are determined. Changes in job performance, job
conditions, and estimated profitability, including those arising from contract
penalty provisions, and final contract settlements may result in revisions to
costs and revenues and are recognized in the period in which the revisions are
determined.
 
 Cash and cash equivalents
 
  The Company considers investments in money market accounts and certificates
of deposits purchased with an original maturity of three months or less to be
cash equivalents. Cash payments for interest and taxes were $30,411 and
$283,216, respectively, for the year ended December 31, 1997.
 
 Accounts Receivable
 
  Accounts receivable consists of the following at December 31, 1997:
 
<TABLE>
      <S>                                                            <C>
      Accounts receivable--billed................................... $2,175,051

                                                                     $2,782,678
                                                                     ==========
</TABLE>
 
  The Company considers accounts receivable to be fully collectible;
accordingly, no allowance for doubtful accounts is required.

 Inventories
 
  Inventories consist of parts and supplies for general use and items for
specific jobs. Inventories are stated at lower of cost or market. Cost is
determined using the first-in, first-out method.
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the useful lives of the assets. Expenditures for
major renewals and improvements, which extend the useful lives of existing
equipment, are capitalized and depreciated. The estimated useful lives of
assets are as follows:

                                                                           -----
      <S>                                                                  <C>

      Office equipment....................................................  5-7
      Leasehold improvements..............................................   10
      Other...............................................................   19
</TABLE>
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Upon retirement or disposition of property and equipment, the cost
and related accumulated depreciation are removed from the accounts and any
resulting gain or loss is recognized in the statements of operations.
 
 Income Taxes
 
  Deferred taxes are provided on a liability method whereby deferred tax
assets are recognized for deductible temporary differences and deferred tax
liabilities are recognized for taxable temporary differences. Temporary
differences are the differences between the reported amounts of assets and
liabilities and their tax bases. Deferred tax assets are reduced by a
valuation allowance when, in the opinion of management, it is more likely than
not that some portion or all of the deferred tax assets will not be realized.
Deferred tax assets and liabilities are adjusted for the effects of changes in
tax laws and rates on the date of enactment.
 
 Credit Risk
 
  Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash, accounts receivable
and costs and estimated earnings in excess of billings on uncompleted
contracts.
 
  The Company maintains its cash balances in one financial institution. The
balances are insured by the Federal Deposit Insurance Corporation up to
$100,000. The Company generally has funds deposited in excess of $100,000.
 
  Accounts receivable and costs and estimated earnings in excess of billings
on uncompleted contracts result primarily from contracts with customers
principally in the Company's service area in Jacksonville, Florida. Credit is
extended to customers after an evaluation for credit worthiness; however, the
Company does not require collateral or other security from customers.
 
  The Company's three largest customers accounted for 14%, 8% and 5%,
respectively, of total revenues for the year ended December 31, 1997.

the plan are at the discretion of management. There were no contributions to
the plan for the year ended December 31, 1997.
 
4. LEASES

the shareholders at $4,700 per month. Management intends and has the ability
to continue to renew its lease with related parties. The Company pays all
property taxes, insurance and maintenance. Rent expense for the lease of
building space during the year ended December 31, 1997 was $42,000.

                         NOTES TO FINANCIAL STATEMENTS
 
 (All information with respect to the interim periods ended June 30, 1997 and
                              1998 is unaudited)
 
1. BUSINESS AND ORGANIZATION
 
  Reliable Mechanical, Inc. (the "Company") is a construction contractor
involved in the construction and renovation of mechanical systems on projects
throughout the central and eastern United States and in Puerto Rico. The
Company performs certain construction contracts as a prime contractor and also
acts as a subcontractor on other projects. The work is typically performed
under fixed-price and cost-plus contracts, or time-and-material purchase
requisitions. The length of the Company's contracts vary, but is typically one
to one and a half years in duration.
 
2. SUMMARY OF SIGNIFICANT POLICIES
 
 Interim Financial Information
 
  Interim financial statements as of June 30, 1998 and for the six months
ended June 30, 1997 and 1998, are unaudited, and certain information and
footnote disclosures, normally included in financial statements prepared in
accordance with generally accepted accounting principles, have been omitted.
In the opinion of management, all adjustments, consisting only of normal
recurring adjustments, necessary to fairly present the financial position,
results of operations and cash flows with respect to the interim financial
statements have been included. The results of operations for the interim
periods are not necessarily indicative of the results for the entire fiscal
year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue and Cost Recognition
 
  Revenues from fixed price contracts are recognized on the percentage of
completion method. The completed percentage is measured by the percentage of
cost incurred to date as compared to the estimated total cost for each
contract, including work for approved change orders. Revenue from cost-plus-
fee contracts are recognized on the basis of costs incurred during the period
plus the fee earned, measured by the cost-to-cost method. Revenue from time
and material contracts is accrued at the end of each month based on chargeable
costs incurred through month end. Time and material contracts are billed for
the number of man hours and costs incurred.
 
  Contract costs include all direct material, subcontract and labor costs and
a provision for indirect costs such as indirect labor and equipment costs.
Selling, general and administrative costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted contracts are made in the
period in which such losses are determined. Changes in job performance, job
conditions, and estimated profitability, including those arising from contract
penalty provisions, and final contract settlements may result in revisions to
costs and revenues and are recognized in the period in which the revisions are
determined.
 
 Cash and cash equivalents
 
  For purposes of the statement of cash flows, the Company considers all
highly liquid investments with original maturities of three months of less to
be cash equivalents. Cash payments for taxes were $108,558 for the year ended
December 31, 1997 and $36,980 and $12,840 for the six months ended June 30,
1997 and 1998, respectively.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Accounts Receivable
 
  Accounts receivable--trade consists of the following at December 31, 1997:
 
<TABLE>
      <S>                                                             <C>

                                                                      $6,786,939
                                                                      ==========
</TABLE>
 
  The Company considers accounts receivable to be fully collectible;
accordingly, no allowance for doubtful accounts is required.
 
 Notes Receivable
 
  The notes receivable, including amounts due from related parties, consist of
loans to certain employees and stockholders. Management considers the balances
due from stockholders as current due to the ability of the stockholders to
repay the loans on demand. Interest is accrued on an annual basis at 7%. Non-
stockholder notes receivable are payable in monthly installments and accrue
interest at rates ranging from 7% to 9%.
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight line method over the useful lives of the assets. Expenditures for
major renewals and improvements, which extend the useful lives of existing
equipment, are capitalized and depreciated. The estimated useful lives of
assets are 5 years for all classes of assets.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Upon retirement or disposition of property and equipment, the cost
and related accumulated depreciation are removed from the accounts and any
resulting gain or loss is recognized in the statements of operations.
 
 Short-term Investments and Marketable Securities
 
  Short-term investments are carried at cost, which approximates fair value.
The Company accounts for marketable securities in accordance with SFAS No.
115, Accounting for Certain Investments in Debt and Equity Securities. All of
the Company's marketable securities (all of which are equity securities and
investments in mutual funds) have been classified as available for sale with
unrealized gains or losses recorded as a separate component of shareholders'
equity. As of December 31, 1997 the cost of the marketable securities was
$422,821 and unrealized gains were $212,907, with no unrealized losses.
 
 Income Taxes
 
  The shareholders of the Company elected to be taxed for federal tax purposes
as an S Corporation whereby the shareholders' respective equitable shares in
the taxable income of the Company are reportable on their individual tax
returns. The Company has made distributions to the shareholders each year at
least in amounts necessary to pay personal income taxes payable on the
Company's taxable income.
 
  Due to its operations in Puerto Rico, the Company is required to pay
corporate income taxes in Puerto Rico. These amounts are recorded as income
tax expense. The total tax expense for the year ended December 31, 1997 was
$48,060. As of December 31, 1997, deferred income taxes are insignificant.
 
 New Accounting Pronouncement
 
  In June 1997, SFAS No. 130, Reporting Comprehensive Income was issued. This
statement establishes standards for reporting and displaying comprehensive
income and its components in a financial statement that is
 
                                     F-261

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
displayed with the same prominence as other financial statements.
Reclassification of the financial statements for
earlier periods, provided for comparative purposes, is required. The statement
also requires the accumulated balance of other comprehensive income to be
displayed separately in the equity section of the balance sheet. This
statement is effective for fiscal years beginning after December 15, 1997.
Total comprehensive income for the six months ended June 30, 1997 and 1998 was
$1,379,095 and $1,496,338, respectively.
 
3. EMPLOYEE BENEFIT PLANS
 
  The Company has a profit-sharing and a 401(k) plan covering all employees
meeting certain age and service requirements. The contribution to the plans,
which is determined at the discretion of management and is charged to expense
and funded on a current basis, was $99,086 for the year ended December 31,
1997.
 
  The Company has a deferred compensation arrangement covering certain key
employees. The contribution to the plan, which is determined at the discretion
of management and is charged to expense was $73,750 for the year ended
December 31, 1997. These amounts are included on the balance sheets as
deferred compensation. At the end of a specified period of service (10 years),
if still employed by the Company, the employee is entitled to the vested
amount. Vesting under the plan occurs beginning in the tenth year of
employment at which time the employee is vested in contributions of the first
year of service. In each successive year, the employee vests in the
contributions of the next succeeding year.
 
4. LEASES
 
  The Company leases its offices and sheet metal shop from certain
shareholders under an operating lease that expires December 31, 1998. The
lease requires monthly rent of $4,000 and rent expense of $48,000 was recorded
for the year ended December 31, 1997.

                                                                      =========
</TABLE>
 
7. CONTINGENCIES
 
  In the normal course of business the Company experiences various claims and
lawsuits from third parties. During 1997, the Company was a named defendant in
a claim from a subcontractor alleging non-performance under a contract.
Management believes that adequate provision has been made in the accompanying
financial statements to cover any potential exposure related to this lawsuit.
 
8. BANK LINE OF CREDIT
 
  The Company has a revolving line of credit with a bank in the amount of
$2,000,000 with no amount outstanding at December 31, 1997. The credit
agreement provides for revolving credit through September 1, 1998 and is
secured by all business assets. Interest is computed at the bank's prime rate
(8.5% at December 31, 1997).
 
9. STOCK PURCHASE AGREEMENT
 
  The Company is obligated to purchase up to 185.18 shares of common stock of
the Company from certain shareholders upon written request by the
shareholders. The purchase price is to be based on the book value of the
Company, which was $5,655 per share at December 31, 1997. These shares of the
Company's common stock are classified outside of shareholders' equity because
of this put feature. Such shares are valued based on the book value of the
shares at the balance sheet date. Changes in book value are recorded directly
to shareholders' equity.
 
10. CONCENTRATIONS OF RISK
 
  During the year ended December 31, 1997, 17% of the Company's revenues were
derived from work performed in Puerto Rico. In addition, the Company's largest
customer, the U. S. government, accounted for 84% of total revenues for the
year ended December 31, 1997 and 92% of the balance of accounts receivable-
trade at December 31, 1997.
 
11. FINANCIAL INSTRUMENTS
 
  The Company's financial instruments consist of cash and cash equivalents,
short-term investments, notes receivable (including due from related parties)
and marketable securities (carried at fair value). The Company believes the
carrying value of these instruments on the accompanying balance sheet at
December 31, 1997 approximates their fair value.
 
12. SUBSEQUENT EVENT
 
  Effective August 14, 1998, Group Maintenance America Corp. (GroupMAC)
acquired all of the outstanding shares of the Company for a combination of
cash and common stock of GroupMAC.

                         NOTES TO FINANCIAL STATEMENTS
 
 (ALL INFORMATION WITH RESPECT TO THE INTERIM PERIODS ENDED JUNE 30, 1997 AND
                              1998 IS UNAUDITED)
 
1. BUSINESS AND ORGANIZATION
 
  Romanoff Electric Corp. ("the Company") is a full-service unionized
electrical contractor serving principally northwest Ohio and southeast
Michigan. The Company performs work under cost-plus-fee contracts, fixed price
contracts, and time and material contracts. The length of individual contracts
varies, but typically is less than one year.
 
2. SUMMARY OF SIGNIFICANT POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the six months ended June 30, 1997 and
1998 and as of June 30, 1998 are unaudited, and certain information and
footnote disclosures, normally included in financial statements prepared in
accordance with generally accepted accounting principles, have been omitted.
In the opinion of management, all adjustments, consisting only of normal
recurring adjustments, necessary to fairly present the financial position,
results of operations and cash flows with respect to the interim financial
statements, have been included. The results of operations for the interim
periods are not necessarily indicative of the results for the entire fiscal
year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue and Cost Recognition
 
  Revenues from fixed price contracts are recognized on the percentage of
completion method. The completed percentage is measured by the percentage of
cost incurred to date as compared to the estimated total cost for each
contract, including work for approved change orders. Revenue from cost-plus-
fee contracts are recognized on the basis of costs incurred during the period
plus the fee earned, measured by the cost-to-cost method. Revenue from time
and material contracts is accrued at the end of each month based on chargeable
costs incurred through month end. Time and material contracts are billed for
the number of man hours and costs incurred.
 
  Contract costs include all direct material, subcontract and labor costs and
a provision for indirect costs such as indirect labor and equipment costs.
Selling, general and administrative costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted contracts are made in the
period in which such losses are determined. Changes in job performance, job
conditions, and estimated profitability, including those arising from contract
penalty provisions, and final contract settlements may result in revisions to
costs and revenues and are recognized in the period in which the revisions are
determined.
 
 Cash and cash equivalents
 
  For purposes of the statement of cash flows, the Company considers
investments in money market accounts and certificates of deposits purchased
with an original maturity of three months or less to be cash equivalents. Cash
payments for interest were $29,774, $5,456 and $2,459 for the year ended
December 31, 1997 and the six months ended June 30, 1997 and 1998,
respectively. Cash payments for taxes were $47,955, $5,193 and $27,293 for the
year ended December 31, 1997 and six months ended June 30, 1997 and 1998,
respectively.

on uncompleted contracts result primarily from contracts with customers

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Article 2.02A of the TBCA provides, in relevant part, as follows:
 
  Subject to the provisions of Sections B and C of this Article, each
  corporation shall have power:
 
    (16) to indemnify directors, officers, employees, and agents of the
  corporation and to purchase and maintain liability insurance for those
  persons.
 
  Article IX of the Articles of Incorporation of the Company (therein referred
to as the "Corporation") provides as follows:
 
    1. Right to Indemnification. Each person who was or is made a party or is
  threatened to be made a party to or is otherwise involved in any
  threatened, pending or completed action, suit or proceeding, whether civil,
  criminal, administrative, arbitrative or investigative, any appeal in such
  action, suit or proceeding, and any inquiry or investigation that would
  lead to such action, suit or proceeding (hereinafter a "proceeding"), by
  reason of the fact that he or she, or a person of whom he or she is the
  legal representative, is or was a director or officer of the Corporation or
  is or was serving at the request of the Corporation as a director or
  officer of another corporation or of a partnership, joint venture, trust or
  other enterprise, including service with respect to any employee benefit
  plan (hereinafter an "indemnitee"), whether the basis of such proceeding is
  alleged action in an official capacity as a director or officer or in any
  other capacity while serving as a director or officer, shall be indemnified
  and held harmless by the Corporation to the fullest extent authorized by
  the TBCA, as the same exists or may hereafter be amended (but, in the case
  of any such amendment, only to the extent that such amendment permits the
  Corporation to provide broader indemnification rights than permitted prior
  thereto), against all judgments, fines, penalties (including excise tax and
  similar taxes), settlements, and reasonable expenses actually incurred by
  such indemnitee in connection therewith. The right to indemnification
  conferred in this Article shall include the right to be paid by the
  Corporation the expenses incurred in defending any such proceeding in
  advance of its final disposition (hereinafter an "advancement of
  expenses"); provided, however, that, if the TBCA requires, an advancement
  of expenses incurred by an indemnitee shall be made only upon delivery to
  the Corporation of an undertaking, by or on behalf of such indemnitee, to
  repay all amounts so advanced if it shall ultimately be determined that
  such indemnitee is not entitled to be indemnified for such expenses under
  this Article or otherwise.
 
    2. Insurance. The Corporation may purchase and maintain insurance, at its
  expense, on behalf of any indemnitee against any liability asserted against
  him and incurred by him in such a capacity or arising out of his status as
  a representative of the Corporation, whether or not the Corporation would
  have the power to indemnify such person against such expense, liability or
  loss under the TBCA.
 
    3. Indemnity of Employees and Agents of the Corporation. The Corporation
  may, to the extent authorized from time to time by the board of directors,
  grant rights to indemnification and to the advancement of expenses to any
  employee or agent of the Corporation to the fullest extent of the
  provisions of this Article or as otherwise permitted under the TBCA with
  respect to the indemnification and advancement of expenses of directors and
  officers of the Corporation.
 
  The Company has entered into indemnity agreements with its directors and
certain key officers pursuant to which the Company generally is obligated to
indemnify its directors and such officers to the full extent permitted by the
TBCA as described above.
 
  The Company has purchased liability insurance policies covering the
directors and officers of the Company, including, to provide protection where
the Company cannot legally indemnify a director or officer and where a claim
arises under the Employee Retirement Income Security Act of 1974 against a
director or officer based on an alleged breach of fiduciary duty or other
wrongful act.

ITEM 22. UNDERTAKINGS.
 
  (a) Regulation S-K, Item 512 Undertakings
 
    (1) The undersigned registrant hereby undertakes:
 
      (i) To file, during any period in which offers or sales are being
    made, a post-effective amendment to this registration statement:
 
        (a) To include any prospectus required by section 10(a)(3) of the
      Securities Act of 1933;
 
        (b) To reflect in the prospectus any facts or events arising after
      the effective date of the registration statement (or the most recent
      post-effective amendment thereof) which, individually or in the
      aggregate, represent a fundamental change in the information set
      forth in the registration statement. Notwithstanding the foregoing,
      any increase or decrease in volume of securities offered (if the
      total dollar value of securities offered would not exceed that which
      was registered) and any deviation from the low or high end of the
      estimated maximum offering range may be reflected in the form of
      prospectus filed with the Commission pursuant to Rule 424(b) if, in
      the aggregate, the changes in volume and price represent no more
      than a 20% change in the maximum offering price set forth in the
      "Calculation of Registration Fee" table in the effective
      registration statement.
 
        (c) To include any material information with respect to the plan
      of distribution not previously disclosed in the registration
      statement or any material change to such information in the
      registration statement;
 
      (ii) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be
    deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall
    be deemed to be the initial bona fide offering thereof.
 
      (iii) To remove from registration by means of a post-effective
    amendment any of the securities being registered which remain unsold at
    the termination of the offering.
 
    (2) Registration on Form S-4 of Securities Offered for Resale.
 
      (i) The undersigned hereby undertakes as follows: That prior to any
    public reoffering of the securities registered hereunder through the
    use of a prospectus which is a part of this registration statement, by
    any person or party who is deemed to be an underwriter within the
    meaning of Rule 145(c), the issuer undertakes that such reoffering
    prospectus will contain the information called for by the applicable
    registration form with respect to reofferings by person who may be
    deemed underwriters, in addition to the information called for by the
    other Items of the applicable form.
 
      (ii) The registrant undertakes that every prospectus (a) that is
    filed pursuant to the paragraph immediately preceding, or (b) that
    purports to meet the requirements of section 10(a)(3) of the Act and is
    used in connection with an offering of securities subject to Rule 415,
    will be filed as a part of an amendment to the registration statement
    and will not be used until such amendment is effective, and that, for
    purposes of determining any liability under the Securities Act of 1933,
    each such post-effective amendment shall be deemed to be a new
    registration statement relating to the securities offered therein, and
    the offering of new securities at that time shall be deemed to be the
    initial bona fide offering thereof.
 
    (3) Insofar as indemnification for liabilities arising under the
  Securities Act may be permitted to directors, officers and controlling
  persons of the Company pursuant to the foregoing provisions, or otherwise,
  the Company has been advised that in the opinion of the Commission such
  indemnification is against public policy as expressed in the Securities Act
  and is, therefore, unenforceable. In the event that a claim for
  indemnification against such liabilities (other than payment by the Company
  of expenses incurred or paid by a director, officer or controlling person
  of the Company in the successful defense of any action, suit or proceeding)
  is asserted by such director, officer or controlling person in connection
  with the securities
 
                                     II-5
<PAGE>
 
  being registered, the Company will, unless in the opinion of its counsel
  the matter has been settled by controlling precedent, submit to a court of
  appropriate jurisdiction the question whether such indemnification by it is
  against public policy as expressed in the Securities Act and will be
  governed by the final adjudication of such issue.
 
  (b) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4 of this Form, within one business day of receipt of such request, and
to send the incorporated documents by first class mail or other equally prompt
means. This includes information contained in documents filed subsequent to
the effective date of the registration statement through the date of
responding to the request.
 
  (c) The undersigned hereby undertakes to supply by means of a supplement or
a post-effective amendment all information concerning a transaction, and the
company being acquired therein, that was not the subject of and included in
the registration statement when it became effective.

Group Maintenance America Corp.
Eight Greenway Plaza, Suite 1500
Houston, Texas 77046

Ladies and Gentlemen:

We have acted as counsel to Group Maintenance America Corp., a Texas corporation
(the "Company"), in connection with the preparation of its Registration
Statement on Form S-4 (the "Registration Statement") filed by the Company under
the Securities Act of 1933, as amended (the "Securities Act").  The Registration
Statement relates to the offering and sale by the Company of up to 7,000,000
shares of its common stock, par value $.001 per share (the "Common Stock"),
which the Company will issue and sell from time to time in connection with
business combinations.

We have examined originals or copies of:  (i) the Articles of Incorporation of
the Company, as amended, (ii) the Bylaws of the Company, as amended; (iii)
certain resolutions of the Board of Directors of the Company; and (iv) such
other documents and records as we have deemed necessary and relevant for the
purposes hereof.  We have relied upon certificates of public officials and
officers of the Company as to certain matters of fact relating to this opinion
and have made such investigations of law as we have deemed necessary and
relevant as a basis hereof.  We have not independently verified any factual
matter relating to this opinion.  In such examination, we have assumed the
genuineness of all signatures, the authenticity of all documents, certificates
and records submitted to us as copies, and the conformity to original documents,
certificates and records of all documents, certificates and records submitted to
us as copies.  We have also assumed that (i) the Registration Statement, and any
amendments thereto (including post-effective amendments), will have become

                             EMPLOYMENT AGREEMENT


     This Employment Agreement ("Agreement") is made as of October 24, 1996, by

     1.   Employment.  The Company hereby agrees to employ the Employee and the
Employee hereby agrees to work for the Company upon the terms and conditions set

     2.   Term of Employment.  This Agreement shall continue in effect for an
initial term of three (3) years from the date of this Agreement, unless
terminated in accordance with Section 7, and shall be extended from year to year
thereafter, unless terminated effective as of the end of the initial term or any
one-year extension thereafter by written notice from the Company to Employee, or
by written notice of Employee to the Company, delivered not less than ninety
(90) days prior to the end of the initial term, or the anniversary of such one-

devote his skill, energy and best efforts to the faithful discharge of his
duties as an employee of the Company.  The Employee agrees that in the provision
of all services to the Company, he will comply with and follow all directives,
policies, standards and regulations from time to time established by the Board
of Directors of the Company.

          (c) The Employee represents and warrants that he is under no
contractual or other restrictions or obligations which will significantly limit
his activities on behalf of the Company or which will prohibit or limit the
disclosure or use of by the Employee of any information which directly or
indirectly relates to the nature of the Company or the services to be rendered
by the Employee under this Agreement.

          (d) To the extent they relate to, or result from, directly or
indirectly, the actual or anticipated operations of the Company, the Employee
hereby agrees that all patents, trademarks, copyrights, trade secrets, and other
intellectual property rights, all inventions, whether or not patentable and any
product, drawing, design, recording, writing, literary work or other author's
work, in any other tangible form developed in whole or in part by Employee
during the term of this Agreement, or otherwise developed, purchased or acquired
by Employer, shall be the exclusive

                                       1
<PAGE>
 
property of the Employer ("Intellectual Property"), and unless otherwise agreed
by Employer, all right, title and interest therein shall remain in Employer.

          (e) The Employee will hold all Intellectual Property and Confidential
Information (defined below) in trust for the Company and will deliver all
Intellectual Property and Confidential Information in his possession or control
to the Company upon request and, in any event, at the end of his employment with
the Company.  The Employee will promptly disclose to the Company all
Confidential Information, as well as any business opportunity which comes to his

himself or any other party without the prior written consent of the Company.

          (f) The Employee shall assign and does hereby assign to the Company
all property rights that he may now or hereafter have in the Intellectual
Property and Confidential Information. The Employee shall take such action,
including, but not limited to, the execution, acknowledgment, delivery and
assistance in preparation of documents, and the giving of testimony, as may be
requested by the Company to evidence, transfer, vest or confirm the Company's
right, title and interest in the Intellectual Property.

          (g) The Employee will not contest the validity of any invention, any
copyright, any trademark or any mask work registration owned by or vesting in
the Company under this Agreement.

          (h) The terms and conditions of Sections 3(d), (e), (f), and (g) will
survive the termination of this Agreement for any reason whatsoever.

     4.  Compensation.

          (a) During the first year, the Company shall pay the Employee a base
salary, payable semi-monthly, in equal installments at a rate equal to $140,000
per year.  In each subsequent year of this Agreement, the Company shall pay to
the Employee a salary equal to the greater of (i) his salary for the immediately
preceding year or (ii) if determined otherwise by the Board of Directors, a
salary determined by the Board of Directors following its annual salary and
performance review.

          (b) Employee shall receive an annual cash performance bonus of from
zero-percent (0%) to one hundred percent (100%) of Employee's annual base salary
for the calendar year during the term of this Agreement to be determined
according to the following procedure.  The Board of Directors of the Company, or
the Compensation Committee of the Board of Directors, if so authorized, shall
establish specific annual performance goals for the Company and for Employee
with respect to each calendar year during the term of this Agreement commencing
on January 1, 1997. Such goals shall be communicated to Employee not later than
the end of the first quarter of the applicable calendar year.  At the end of
each calendar year during the term of this Agreement, or within a reasonable
time thereafter, the Board of Directors of the Company, or the Compensation
Committee of the Board of Directors, if so authorized, shall review the actual
performance of the Company and Employee, giving due consideration to market and
other developments outside of the control or influence of Employee and the
Company, and based upon the extent to which the

                                       2
<PAGE>
 
applicable annual performance goals have been achieved, shall determine in its
sole and absolute discretion, the amount of performance bonus payable to
Employee with respect to such year.

          (c) All payments of salary and other compensation to the Employee
shall be made after deduction of any taxes which are required to be withheld
with respect thereto under applicable federal and state laws.

     5.   Senior Management Stock Options.

          (a) Employee is hereby granted options (the "1996 Senior Management
Options") to purchase 115,000 shares of the common stock of the Company as
presently constituted, at an exercise price of $1.231 per share.  The 1996
Senior Management Options shall vest ratably as of the earlier of (i) the end of
the three calendar years, 1997, 1998, 1999, or (ii) when and as the Designated
Value of the Company's common stock has achieved the milestones of $7.00, $9.00,
and $11.00 per share, respectively.  The 1996 Senior Management Options may be
exercised in whole or in part, from time to time, at any time after vesting
through December 31, 2006 by the payment of cash or the tender of shares of the
Company's common stock (including shares of common stock otherwise receivable as
a result of the exercise of said options or any other options) having a
Designated Value equal to the exercise price of the 1996 Senior Management
Options being exercised.  To the extent that certain Shareholders Agreement of
even date herewith among the Corporation and the shareholders of the Company,
including Employee (the "Shareholders Agreement") is in effect at the time
Employee exercises any of the Senior Management Options, such shares of the
Company's common stock issued to Employee shall be subject to the provisions of
the Shareholders Agreement.

          (b) Commencing with the Company's initial public offering of Common
Stock and for each partial or full calendar year thereafter during the term
hereof, provided Employee is then serving as an employee of the Company, the
Company shall grant to Employee options (together with the 1996 Senior
Management Options, collectively referred to as the "Senior Management Options")
to purchase such number of additional shares as the Board of Directors of the
Company may determine, on such terms and conditions as shall be established at
such time.

          (c) For purposes hereof, "Designated Value" of the shares on a
specified date shall mean (i) the average of the closing prices of the common
stock on the principal market or registered exchange on which the Company's
common stock is traded (or the average of the closing bid and ask prices, if a
single closing price is not reported for such market) on the ten (10)
consecutive trading days next preceding the date for the determination of such
value, provided that the stock is then traded on the over the counter market or
on the NASDAQ System or any registered securities exchange, or (ii) if not
publicly traded, the book value per share of the Company as of the end of the
calendar quarter next preceding the date of determination of such value.

          (d) From time to time the Company agrees to register under the
Securities Act of 1933 and all applicable state securities laws and regulations
the shares of common stock issuable upon the exercise of the foregoing Senior
Management Options in the same manner as shares issuable under any other stock
options or stock purchase plans of the Company.  Further, the Company agrees to
grant to the Employee "demand" or "piggyback" registration rights with respect
to all such Senior

                                       3
<PAGE>
 
Management Option shares (to the extent same have not been registered), and all
other shares of common stock owned directly or indirectly by the Employee or
Employee's immediate family, equivalent to the "demand" or "piggyback"
registration rights granted under that certain Registration Rights Agreement
dated October 24, 1996, by and among the Company, Gordon Cain and other holders
of common stock of the Company.

     6.   Fringe Benefits; Expenses.

          (a) So long as the Employee is employed by the Company, the Employee
shall participate in all employee benefit plans sponsored by the Company for its
executive employees, including but not limited to vacation policy, sick leave
and disability leave, health insurance, dental insurance and pension and/or
profit sharing plans; provided, however, that except as provided below, the
nature, amount and limitations of such plans shall be determined from time to
time by the Board of Directors of the Company.

          (b) The Company will reimburse the Employee for all reasonable
business expenses incurred by the Employee in the scope of his employment.

          (c) Employees shall be entitled to participate in any other stock
bonus, stock purchase or stock option plan instituted by the Company for its
managers or employees generally in the same manner as any other senior executive
officer of the Company, with proper regard and weight given in the issuance of
shares or the grant of options for the Employee's position (and without
consideration of the above Senior Management Options or any shares of the
Company otherwise owned by Employee directly or indirectly).

          (d) The Company shall make reasonable efforts to provide life
insurance payable to Employee's designated beneficiary in an amount at least
three times Employee's annual base salary.

          (e) The Company shall make a reasonable effort to maintain disability
insurance on behalf of Employee which, as a goal, shall provide for salary
continuation in the event of permanent disability in an amount not less than 60%
of the Employee's regular base salary.

          (f) The Employee shall be entitled to a minimum of three weeks paid
vacation, increasing to four weeks at January 1, 1999.

          (g) The Company will pay all license fees, occupation taxes and
reasonable educational costs and expenses necessary to maintain Employee's good
standing under any professional licenses.

     7.   Termination.

          (a) Employee agrees that this Agreement may be terminated by the
Company with or without "Cause" at any time, subject to the terms of this
Section 7. Such termination shall be effective upon delivery of written notice
to Employee of the Company's election to terminate this Agreement under this
Section 7. "Cause" when used in connection with the termination of

                                       4
<PAGE>
 
employment with the Company, shall mean the termination of the Employee's
employment by the Company by reason of (i) the conviction of the Employee of a
crime involving moral turpitude by a court of competent jurisdiction as to which
no further appeal can be taken; (ii) the proven commission by the Employee of an
act of fraud upon the Company; (iii) the willful and proven misappropriation of
any funds or property of the Company by the Employee; (iv) the willful,
continued and unreasonable failure by the Employee to perform material duties
assigned to him and agreed to by him after reasonable notice and opportunity to
cure such performance; (v) the knowing engagement by the Employee in any direct,
material conflict of interest with the Company without compliance with the
Company's conflict of interest policy, if any, then in effect; (vi) the knowing
engagement by the Employee, without the written approval of the Board of
Directors of the Company, in any activity which competes with the business of
the Company or which would result in a material injury to the Company; or (vii)
the knowing engagement in any activity which would constitute a material
violation of the provisions of the Company's Insider Trading Policy or Business
Ethics Policy, if any, then in effect.

          If the Employee's employment terminates, unless the Company terminates
the Employee's employment under this Agreement for Cause or the Employee
resigns, the Company shall, subject to the terms of Section 7(c) below, and only
if and as long as Employee is not in breach of his obligations under this
Agreement, pay to the Employee an amount equal to twelve (12) months
compensation at his then current salary, payable semimonthly, and shall continue
to provide benefits in the kind and amounts provided up to the date of
termination for said twelve (12) month period including, without limitation,
continuation of any Company-paid benefits as described in Section 6 for the
Employee and his family; provided, however, that in the event that Gordon A.
Cain elects to cease payments of outstanding installments in compliance with the
Subscription Agreement dated October 24, 1996 with the Company, and the Company
elects to terminate Employee under this Section 7, or Employee resigns within 60
days of such termination, then if Employee is not in breach of his obligations
under this Agreement, the Company shall pay to the Employee, in lieu of the
severance payments described above, three (3) months compensation under this
Agreement, payable semi-monthly, and the Company shall continue to provide
benefits in the kind and amount provided up to the date of termination for said
three (3) month period.  Notwithstanding anything in this Agreement to the
contrary, in the event the Employee's employment terminates within six months
after (A) a sale of all or substantially all of the assets of the Company, or
(B) a merger, consolidation, liquidation or reorganization of the Company, in
which the purchaser or the surviving entity, as applicable, adopts  the
Company's obligations under this Agreement, the Company shall pay to the
Employee, an amount equal to two times Employee's severance benefits otherwise
available to Employee under this Agreement.

     In the event that this Agreement is terminated by Company without Cause,
Employee agrees to accept, in full settlement of any and all claims, losses,
damages and other demands which Employee may have arising out of such
termination as liquidated damages and not as a penalty, the applicable amount
which is set out above.  Employee hereby waives any and all rights he may have
to bring any cause of action or proceeding contesting any termination without
Cause, provided, however, that such waiver shall not be deemed to affect
Employee's rights to enforce any other obligations of the Company.  Under no
circumstances shall Employee be entitled to any compensation or confirmation

                                       5
<PAGE>
 
of any benefits under this Agreement for any period of time following his date
of termination if his termination is for Cause.

          (b) If at any time during the term of this Agreement, Employee is
unable due to physical or mental disability, to perform effectively his duties
hereunder, the Company shall continue payment of compensation as provided in
Section 4 during the first twelve (12) month period of such disability to the
extent not covered by the Company's disability insurance policies.  Upon the
expiration of such twelve (12) month period, the Company, at its sole option,
may continue payment of Employee's salary for such additional periods as the
Company elects, or may terminate this Agreement without any further obligations
hereunder.  If Employee should die during the term of this Agreement, Employee's
employment and the Company's obligations hereunder shall terminate as of the end
of the month in which Employee's death occurs and there will be no salary and
benefit continuation period pursuant to Section 7(a).

          (c) So long as Employee receives a severance as provided in Section
7(a) or (b) above, Employee agrees that he will sign any lock-up letters,
standstill agreements, or other similar documentation required by an underwriter
in connection with a public offering of securities by the Company or take other
actions reasonably related thereto as requested by the Board of Directors of the
Company.  Failure to take any such action shall cause Employee to forfeit any
further rights to the salary continuation payments in Section 7(a) or (b).  In
addition, Employee agrees that in such event the Company can seek and obtain
specific performance of such covenant, including any injunction requiring
execution thereof, and the Employee hereby appoints the then current president
of the Company to sign any such documents on his behalf so long as such
documents are prepared on the same basis as other shareholders generally or as
all management shareholders.

     8.   Covenant Not to Compete.

          (a) During the term of this Agreement, Employee will not compete with
the Company or its affiliates, directly or indirectly, either for himself or as
a member of a partnership or as a stockholder (except as a stockholder of less
than one percent (1 %) of the issued and outstanding stock of a publicly-held
company whose gross assets exceed one hundred million dollars), investor, owner,
officer or director of a company or other entity, or as an employee, agent,
associate or consultant of any person, partnership, corporation or other entity,
in any business in competition with that carried on by the Company or any of its
affiliates.

          (b) Employee further agrees that, for a period of six (6) months from
and after the date of termination of Employee's employment under this Agreement,
regardless of the reason for such termination, he will neither represent the
Company nor engage in or carry on, directly or indirectly, either for himself or
as a member of a partnership or as a stockholder (other than as a stockholder of
less than one percent (1 %) of the issued and outstanding stock of a publicly-
held company whose gross assets exceed one hundred million dollars), investor,
owner, officer or director of a company or other entity, or as an employee,
agent, associate or consultant of any person, partnership, corporation or other
entity, any business in any State of the United States or in any other part of
the world which directly competes with any services or products produced, sold,
conducted, developed, or in the process of development by the Company or its
affiliates on the date of
                                       6
<PAGE>
termination of Employee's employment. Notwithstanding the foregoing, nothing
herein shall prevent Employee from working in the indoor air quality, heating,
ventilation and air conditioning or plumbing maintenance services industry,
provided that such activities are in areas not in direct competition with any
services or products produced, sold, conducted, developed, or in the process of
development by the Company or its affiliates on the date of termination of
Employee's employment.

          (c) Employee agrees that the limitations set forth herein on his
rights to compete with the Company and its affiliates are reasonable and
necessary for the protection of the Company and its affiliates.  In this regard,
Employee specifically agrees that the limitations as to period of time and
geographic area, as well as all other restrictions on his activities specified
herein, are reasonable and necessary for the protection of the Company and its
affiliates.  In particular, Employee acknowledges that the parties anticipate
that the Employee will be actively seeking markets for the Company's products
throughout the United States during his employment with the Company.

          (d) Employee agrees that the remedy at law for any breach by him of
this Section 8 will be inadequate and that the Company shall also be entitled to
injunctive relief.

     9.   Confidential Information and Results of Services.  Employee agrees
that during the term of this Agreement, and for five (5) years after his
termination of employment, he will not make use of or disclose, without the
prior consent of the Company, Confidential Information (as hereinafter defined)
relating to the Company, or any of its affiliates, and further agrees, that he
will return to the Company all written materials in his possession embodying
such Confidential Information.  For purposes of this Agreement, "Confidential
Information" includes information conveyed or assigned to the Company by
Employee or conceived, compiled, created, developed, discovered or obtained by
Employee from and during his employment relationship with the Company, whether
solely by the Employee or jointly with others, which concerns the affairs of the
Company or its affiliates and which the Company could reasonably be expected to
desire be held in confidence, or the disclosure of which would likely be
embarrassing, detrimental or disadvantageous to the Company or its affiliates
and without limiting the generality of the foregoing includes information
relating to inventions, and the trade secrets, technologies, algorithms,
products, services, finances, business plans, marketing plans, legal affairs,
supplier lists, client lists, potential clients, business prospects, business
opportunities, personnel assignments, contracts and assets of the Company and
information made available to the Company by other parties under a confidential
relationship.  Confidential Information, however, shall not include information
(a) which is, at the time in question, in the public domain through no wrongful
act of Employee, (b) which is later disclosed to Employee by one not under
obligations of confidentiality to the Company or Employee, (c) which is required
by court or governmental order, law or regulation to be disclosed, or (d) which
the Company has expressly given Employee the right to disclose pursuant to
written agreement.  Employee agrees that the remedy at law for any breach by him
of this Section 9 will be inadequate and that the Company shall also be entitled
to injunctive relief.

     10.  Notice.  All notices, requests, demands and other communications
required by or permitted under this Agreement shall be in writing and shall be
sufficiently delivered if delivered by hand, by courier service, or sent by
registered or certified mail, postage prepaid, to the parties at their
respective addresses listed below:

                                       7
<PAGE>
 
          (a) If to the Employee, to the address set out in the beginning of
this Agreement;

          (b)  If to the Company:

               1225 North Loop West, Suite 324
               Houston, Texas  77008

          Either party may change such party's address by such notice to the
          other parties.

     11.  Assignment.  This Agreement is personal to the Employee, and he shall
not assign any of his rights or delegate any of his duties hereunder without the
prior written consent of the Company.  Neither the employee nor his spouse will
have the right to commute, encumber, or otherwise dispose of any payments under
this Agreement.  The Company shall have the right to assign this Agreement to a
successor in interest in connection with a merger, sale of substantially all
assets, or the like; provided however, that an assignment of this Agreement to
an entity with operations, products or services outside of the industries in
which the Company is then active shall not be deemed to expand the scope of
Employee's covenant not to compete with such operations, products or services
without Employee's written consent.

     12.  Survival.  The provisions of this Agreement shall survive the
termination of the Employee's employment hereunder in accordance with their
terms.

     13.  Governing Law.  This Agreement shall be governed by, and construed and
enforced in accordance with, the laws of Texas.

     14.  Binding Upon Successors.  This Agreement shall be binding upon, and
shall inure to the benefit of, the parties hereto and their respective heirs,
legal representatives, successors and permitted assigns.

     15.  Entire Agreement.  This Agreement constitutes the entire agreement
between the Company and the Employee with respect to the terms of employment of
the Employee by the Company and supersedes all prior agreements and
understandings, whether written or oral, between them concerning such terms of
employment.

     16.  Waiver and Amendments; Cumulative Rights and Remedies.

          (a) This Agreement may be amended, modified or supplemented, and any
obligation hereunder may be waived, only by a written instrument executed by the
parties hereto.  The waiver by either party of a breach of any provision of this
Agreement shall not operate as a waiver of any subsequent breach.

          (b) No failure on the part of any party to exercise, and no delay in
exercising, any right or remedy hereunder shall operate as a waiver hereof, nor
shall any single or partial exercise of any such right or remedy by such party
preclude any other or further exercise thereof or the exercise

                                       8
<PAGE>
 
of any other right or remedy. All rights and remedies hereunder are cumulative
and are in addition to all other rights and remedies provided by law, agreement
or otherwise.

          (c) The Employee's obligations to the Company and the Company's rights
and remedies hereunder are in addition to all other obligations of the Employee
and rights and remedies of the Company created pursuant to any other agreement.

     17.  Construction.  Each party to this Agreement has had the opportunity to
review this Agreement with legal counsel.  This Agreement shall not be construed
or interpreted against any party on the basis that such party drafted or
authored a particular provision, parts of or the entirety of this Agreement.

     18.  Severability.  In the event that any provision or provisions of this
Agreement is held to be invalid, illegal or unenforceable by any court of law or
otherwise, the remaining provisions of this Agreement shall nevertheless
continue to be valid, legal and enforceable as though the invalid or
unenforceable parts had not been included therein.  In addition, in such event
the parties hereto shall negotiate in good faith to modify this Agreement so as
to effect the original intent of the parties as closely as possible with respect
to those provisions which were held to be invalid, illegal or unenforceable.

     IN WITNESS WHEREOF, the Company and the Employee have executed this
Agreement under seal on the date first above written.

     This Employment Agreement ("Agreement") is made as of October 24, 1996, by

"Company"), and RICHARD S. ROUSE, an individual with an address of c/o
Maintenance Specialists of America, Inc., 1225 North Loop West, Suite 324,

     1.   Employment.  The Company hereby agrees to employ the Employee and the
Employee hereby agrees to work for the Company upon the terms and conditions set
forth herein.

     2.   Term of Employment.  This Agreement shall continue in effect for an
initial term of three (3) years from the date of this Agreement, unless
terminated in accordance with Section 7, and shall be extended from year to year
thereafter, unless terminated effective as of the end of the initial term or any
one-year extension thereafter by written notice from the Company to Employee, or
by written notice of Employee to the Company, delivered not less than ninety
(90) days prior to the end of the initial term, or the anniversary of such one-
year extension, as applicable.

     3.   Scope of Duties; Representations and Warranties.

          (a) The Employee shall be initially employed by the Company as its

          (b) So long as he is employed by the Company, the Employee shall
devote his skill, energy and best efforts to the faithful discharge of his
duties as an employee of the Company.  The Employee agrees that in the provision
of all services to the Company, he will comply with and follow all directives,
policies, standards and regulations from time to time established by the Board
of Directors of the Company.

          (c) The Employee represents and warrants that he is under no
contractual or other restrictions or obligations which will significantly limit
his activities on behalf of the Company or which will prohibit or limit the
disclosure or use of by the Employee of any information which directly or
indirectly relates to the nature of the Company or the services to be rendered
by the Employee under this Agreement.

          (d) To the extent they relate to, or result from, directly or
indirectly, the actual or anticipated operations of the Company, the Employee
hereby agrees that all patents, trademarks, copyrights, trade secrets, and other
intellectual property rights, all inventions, whether or not patentable and any
product, drawing, design, recording, writing, literary work or other author's
work, in any other tangible form developed in whole or in part by Employee
during the term of this Agreement, or otherwise developed, purchased or acquired
by Employer, shall be the exclusive

                                       1
<PAGE>
 
property of the Employer ("Intellectual Property"), and unless otherwise agreed
by Employer, all right, title and interest therein shall remain in Employer.

          (e) The Employee will hold all Intellectual Property and Confidential
Information (defined below) in trust for the Company and will deliver all
Intellectual Property and Confidential Information in his possession or control
to the Company upon request and, in any event, at the end of his employment with
the Company.  The Employee will promptly disclose to the Company all
Confidential Information, as well as any business opportunity which comes to his
attention during the term of his employment with the Company.  The Employee will
not take advantage of or divert any business opportunity for the benefit of
himself or any other party without the prior written consent of the Company.

          (f) The Employee shall assign and does hereby assign to the Company
all property rights that he may now or hereafter have in the Intellectual
Property and Confidential Information. The Employee shall take such action,
including, but not limited to, the execution, acknowledgment, delivery and
assistance in preparation of documents, and the giving of testimony, as may be
requested by the Company to evidence, transfer, vest or confirm the Company's
right, title and interest in the Intellectual Property.

          (g) The Employee will not contest the validity of any invention, any
copyright, any trademark or any mask work registration owned by or vesting in
the Company under this Agreement.

          (h) The terms and conditions of Sections 3(d), (e), (f), and (g) will
survive the termination of this Agreement for any reason whatsoever.

     4.  Compensation.

          (a) During the first year, the Company shall pay the Employee a base
salary, payable semi-monthly, in equal installments at a rate equal to $140,000
per year.  In each subsequent year of this Agreement, the Company shall pay to
the Employee a salary equal to the greater of (i) his salary for the immediately
preceding year or (ii) if determined otherwise by the Board of Directors, a
salary determined by the Board of Directors following its annual salary and
performance review.

          (b) Employee shall receive an annual cash performance bonus of from
zero-percent (0%) to one hundred percent (100%) of Employee's annual base salary
for the calendar year during the term of this Agreement to be determined
according to the following procedure.  The Board of Directors of the Company, or
the Compensation Committee of the Board of Directors, if so authorized, shall
establish specific annual performance goals for the Company and for Employee
with respect to each calendar year during the term of this Agreement commencing
on January 1, 1997. Such goals shall be communicated to Employee not later than
the end of the first quarter of the applicable calendar year.  At the end of
each calendar year during the term of this Agreement, or within a reasonable
time thereafter, the Board of Directors of the Company, or the Compensation
Committee of the Board of Directors, if so authorized, shall review the actual
performance of the Company and Employee, giving due consideration to market and
other developments outside of the control or influence of Employee and the
Company, and based upon the extent to which the

                                       2
<PAGE>
 
applicable annual performance goals have been achieved, shall determine in its
sole and absolute discretion, the amount of performance bonus payable to
Employee with respect to such year.

          (c) All payments of salary and other compensation to the Employee
shall be made after deduction of any taxes which are required to be withheld
with respect thereto under applicable federal and state laws.

     5.   Senior Management Stock Options.

          (a) Employee is hereby granted options (the "1996 Senior Management
Options") to purchase 100,000 shares of the common stock of the Company as
presently constituted, at an exercise price of $1.231 per share.  The 1996
Senior Management Options shall vest ratably as of the earlier of (i) the end of
the three calendar years, 1997, 1998, 1999, or (ii) when and as the Designated
Value of the Company's common stock has achieved the milestones of $7.00, $9.00,
and $11.00 per share, respectively.  The 1996 Senior Management Options may be
exercised in whole or in part, from time to time, at any time after vesting
through December 31, 2006 by the payment of cash or the tender of shares of the
Company's common stock (including shares of common stock otherwise receivable as
a result of the exercise of said options or any other options) having a
Designated Value equal to the exercise price of the 1996 Senior Management
Options being exercised.  To the extent that certain Shareholders Agreement of
even date herewith among the Corporation and the shareholders of the Company,
including Employee (the "Shareholders Agreement") is in effect at the time
Employee exercises any of the Senior Management Options, such shares of the
Company's common stock issued to Employee shall be subject to the provisions of
the Shareholders Agreement.

          (b) Commencing with the Company's initial public offering of Common
Stock and for each partial or full calendar year thereafter during the term
hereof, provided Employee is then serving as an employee of the Company, the
Company shall grant to Employee options (together with the 1996 Senior
Management Options, collectively referred to as the "Senior Management Options")
to purchase such number of additional shares as the Board of Directors of the
Company may determine, on such terms and conditions as shall be established at
such time.

          (c) For purposes hereof, "Designated Value" of the shares on a
specified date shall mean (i) the average of the closing prices of the common
stock on the principal market or registered exchange on which the Company's
common stock is traded (or the average of the closing bid and ask prices, if a
single closing price is not reported for such market) on the ten (10)
consecutive trading days next preceding the date for the determination of such
value, provided that the stock is then traded on the over the counter market or
on the NASDAQ System or any registered securities exchange, or (ii) if not
publicly traded, the book value per share of the Company as of the end of the
calendar quarter next preceding the date of determination of such value.

          (d) From time to time the Company agrees to register under the
Securities Act of 1933 and all applicable state securities laws and regulations
the shares of common stock issuable upon the exercise of the foregoing Senior
Management Options in the same manner as shares issuable under any other stock
options or stock purchase plans of the Company.  Further, the Company agrees to
grant to the Employee "demand" or "piggyback" registration rights with respect
to all such Senior

                                       3
<PAGE>
 
Management Option shares (to the extent same have not been registered), and all
other shares of common stock owned directly or indirectly by the Employee or
Employee's immediate family, equivalent to the "demand" or "piggyback"
registration rights granted under that certain Registration Rights Agreement
dated October 24, 1996, by and among the Company, Gordon Cain and other holders
of common stock of the Company.

     6.   Fringe Benefits; Expenses.

          (a) So long as the Employee is employed by the Company, the Employee
shall participate in all employee benefit plans sponsored by the Company for its
executive employees, including but not limited to vacation policy, sick leave
and disability leave, health insurance, dental insurance and pension and/or
profit sharing plans; provided, however, that except as provided below, the
nature, amount and limitations of such plans shall be determined from time to
time by the Board of Directors of the Company.

          (b) The Company will reimburse the Employee for all reasonable
business expenses incurred by the Employee in the scope of his employment.

          (c) Employees shall be entitled to participate in any other stock
bonus, stock purchase or stock option plan instituted by the Company for its
managers or employees generally in the same manner as any other senior executive
officer of the Company, with proper regard and weight given in the issuance of
shares or the grant of options for the Employee's position (and without
consideration of the above Senior Management Options or any shares of the
Company otherwise owned by Employee directly or indirectly).

          (d) The Company shall make reasonable efforts to provide life
insurance payable to Employee's designated beneficiary in an amount at least
three times Employee's annual base salary.

          (e) The Company shall make a reasonable effort to maintain disability
insurance on behalf of Employee which, as a goal, shall provide for salary
continuation in the event of permanent disability in an amount not less than 60%
of the Employee's regular base salary.

          (f) The Employee shall be entitled to a minimum of three weeks paid
vacation, increasing to four weeks at January 1, 1999.

          (g) The Company will pay all license fees, occupation taxes and
reasonable educational costs and expenses necessary to maintain Employee's good
standing under any professional licenses.

     7.   Termination.

          (a) Employee agrees that this Agreement may be terminated by the
Company with or without "Cause" at any time, subject to the terms of this
Section 7. Such termination shall be effective upon delivery of written notice
to Employee of the Company's election to terminate this Agreement under this
Section 7. "Cause" when used in connection with the termination of

                                       4
<PAGE>
 
employment with the Company, shall mean the termination of the Employee's
employment by the Company by reason of (i) the conviction of the Employee of a
crime involving moral turpitude by a court of competent jurisdiction as to which
no further appeal can be taken; (ii) the proven commission by the Employee of an
act of fraud upon the Company; (iii) the willful and proven misappropriation of
any funds or property of the Company by the Employee; (iv) the willful,
continued and unreasonable failure by the Employee to perform material duties
assigned to him and agreed to by him after reasonable notice and opportunity to
cure such performance; (v) the knowing engagement by the Employee in any direct,
material conflict of interest with the Company without compliance with the
Company's conflict of interest policy, if any, then in effect; (vi) the knowing
engagement by the Employee, without the written approval of the Board of
Directors of the Company, in any activity which competes with the business of
the Company or which would result in a material injury to the Company; or (vii)
the knowing engagement in any activity which would constitute a material
violation of the provisions of the Company's Insider Trading Policy or Business
Ethics Policy, if any, then in effect.

          If the Employee's employment terminates, unless the Company terminates
the Employee's employment under this Agreement for Cause or the Employee
resigns, the Company shall, subject to the terms of Section 7(c) below, and only
if and as long as Employee is not in breach of his obligations under this
Agreement, pay to the Employee an amount equal to twelve (12) months
compensation at his then current salary, payable semimonthly, and shall continue
to provide benefits in the kind and amounts provided up to the date of
termination for said twelve (12) month period including, without limitation,
continuation of any Company-paid benefits as described in Section 6 for the
Employee and his family; provided, however, that in the event that Gordon A.
Cain elects to cease payments of outstanding installments in compliance with the
Subscription Agreement dated October 24, 1996 with the Company, and the Company
elects to terminate Employee under this Section 7, or Employee resigns within 60
days of such termination, then if Employee is not in breach of his obligations
under this Agreement, the Company shall pay to the Employee, in lieu of the
severance payments described above, three (3) months compensation under this
Agreement, payable semi-monthly, and the Company shall continue to provide
benefits in the kind and amount provided up to the date of termination for said
three (3) month period.  Notwithstanding anything in this Agreement to the
contrary, in the event the Employee's employment terminates within six months
after (A) a sale of all or substantially all of the assets of the Company, or
(B) a merger, consolidation, liquidation or reorganization of the Company, in
which the purchaser or the surviving entity, as applicable, adopts  the
Company's obligations under this Agreement, the Company shall pay to the
Employee, an amount equal to two times Employee's severance benefits otherwise
available to Employee under this Agreement.

     In the event that this Agreement is terminated by Company without Cause,
Employee agrees to accept, in full settlement of any and all claims, losses,
damages and other demands which Employee may have arising out of such
termination as liquidated damages and not as a penalty, the applicable amount
which is set out above.  Employee hereby waives any and all rights he may have
to bring any cause of action or proceeding contesting any termination without
Cause, provided, however, that such waiver shall not be deemed to affect
Employee's rights to enforce any other obligations of the Company.  Under no
circumstances shall Employee be entitled to any compensation or confirmation

                                       5
<PAGE>
 
of any benefits under this Agreement for any period of time following his date
of termination if his termination is for Cause.

          (b) If at any time during the term of this Agreement, Employee is
unable due to physical or mental disability, to perform effectively his duties
hereunder, the Company shall continue payment of compensation as provided in
Section 4 during the first twelve (12) month period of such disability to the
extent not covered by the Company's disability insurance policies.  Upon the
expiration of such twelve (12) month period, the Company, at its sole option,
may continue payment of Employee's salary for such additional periods as the
Company elects, or may terminate this Agreement without any further obligations
hereunder.  If Employee should die during the term of this Agreement, Employee's
employment and the Company's obligations hereunder shall terminate as of the end
of the month in which Employee's death occurs and there will be no salary and
benefit continuation period pursuant to Section 7(a).

          (c) So long as Employee receives a severance as provided in Section
7(a) or (b) above, Employee agrees that he will sign any lock-up letters,
standstill agreements, or other similar documentation required by an underwriter
in connection with a public offering of securities by the Company or take other
actions reasonably related thereto as requested by the Board of Directors of the
Company.  Failure to take any such action shall cause Employee to forfeit any
further rights to the salary continuation payments in Section 7(a) or (b).  In
addition, Employee agrees that in such event the Company can seek and obtain
specific performance of such covenant, including any injunction requiring
execution thereof, and the Employee hereby appoints the then current president
of the Company to sign any such documents on his behalf so long as such
documents are prepared on the same basis as other shareholders generally or as
all management shareholders.

     8.   Covenant Not to Compete.

          (a) During the term of this Agreement, Employee will not compete with
the Company or its affiliates, directly or indirectly, either for himself or as
a member of a partnership or as a stockholder (except as a stockholder of less
than one percent (1 %) of the issued and outstanding stock of a publicly-held
company whose gross assets exceed one hundred million dollars), investor, owner,
officer or director of a company or other entity, or as an employee, agent,
associate or consultant of any person, partnership, corporation or other entity,
in any business in competition with that carried on by the Company or any of its
affiliates.

          (b) Employee further agrees that, for a period of six (6) months from
and after the date of termination of Employee's employment under this Agreement,
regardless of the reason for such termination, he will neither represent the
Company nor engage in or carry on, directly or indirectly, either for himself or
as a member of a partnership or as a stockholder (other than as a stockholder of
less than one percent (1 %) of the issued and outstanding stock of a publicly-
held company whose gross assets exceed one hundred million dollars), investor,
owner, officer or director of a company or other entity, or as an employee,
agent, associate or consultant of any person, partnership, corporation or other
entity, any business in any State of the United States or in any other part of
the world which directly competes with any services or products produced, sold,
conducted, developed, or in the process of development by the Company or its
affiliates on the date of

                                       6
<PAGE>
 
termination of Employee's employment. Notwithstanding the foregoing, nothing
herein shall prevent Employee from working in the indoor air quality, heating,
ventilation and air conditioning or plumbing maintenance services industry,
provided that such activities are in areas not in direct competition with any
services or products produced, sold, conducted, developed, or in the process of
development by the Company or its affiliates on the date of termination of
Employee's employment.

          (c) Employee agrees that the limitations set forth herein on his
rights to compete with the Company and its affiliates are reasonable and
necessary for the protection of the Company and its affiliates.  In this regard,
Employee specifically agrees that the limitations as to period of time and
geographic area, as well as all other restrictions on his activities specified
herein, are reasonable and necessary for the protection of the Company and its
affiliates.  In particular, Employee acknowledges that the parties anticipate
that the Employee will be actively seeking markets for the Company's products
throughout the United States during his employment with the Company.

          (d) Employee agrees that the remedy at law for any breach by him of
this Section 8 will be inadequate and that the Company shall also be entitled to
injunctive relief.

     9.   Confidential Information and Results of Services.  Employee agrees
that during the term of this Agreement, and for five (5) years after his
termination of employment, he will not make use of or disclose, without the
prior consent of the Company, Confidential Information (as hereinafter defined)
relating to the Company, or any of its affiliates, and further agrees, that he
will return to the Company all written materials in his possession embodying
such Confidential Information.  For purposes of this Agreement, "Confidential
Information" includes information conveyed or assigned to the Company by
Employee or conceived, compiled, created, developed, discovered or obtained by
Employee from and during his employment relationship with the Company, whether
solely by the Employee or jointly with others, which concerns the affairs of the
Company or its affiliates and which the Company could reasonably be expected to
desire be held in confidence, or the disclosure of which would likely be
embarrassing, detrimental or disadvantageous to the Company or its affiliates
and without limiting the generality of the foregoing includes information
relating to inventions, and the trade secrets, technologies, algorithms,
products, services, finances, business plans, marketing plans, legal affairs,
supplier lists, client lists, potential clients, business prospects, business
opportunities, personnel assignments, contracts and assets of the Company and
information made available to the Company by other parties under a confidential
relationship.  Confidential Information, however, shall not include information
(a) which is, at the time in question, in the public domain through no wrongful
act of Employee, (b) which is later disclosed to Employee by one not under
obligations of confidentiality to the Company or Employee, (c) which is required
by court or governmental order, law or regulation to be disclosed, or (d) which
the Company has expressly given Employee the right to disclose pursuant to
written agreement.  Employee agrees that the remedy at law for any breach by him
of this Section 9 will be inadequate and that the Company shall also be entitled
to injunctive relief.

     10.  Notice.  All notices, requests, demands and other communications
required by or permitted under this Agreement shall be in writing and shall be
sufficiently delivered if delivered by hand, by courier service, or sent by
registered or certified mail, postage prepaid, to the parties at their
respective addresses listed below:

                                       7
<PAGE>
 
          (a) If to the Employee, to the address set out in the beginning of
     this Agreement;

          (b)  If to the Company:

               Maintenance Specialists of America, Inc.
               1225 North Loop West, Suite 324
               Houston, Texas  77008

          Either party may change such party's address by such notice to the
          other parties.

     11.  Assignment.  This Agreement is personal to the Employee, and he shall
not assign any of his rights or delegate any of his duties hereunder without the
prior written consent of the Company.  Neither the employee nor his spouse will
have the right to commute, encumber, or otherwise dispose of any payments under
this Agreement.  The Company shall have the right to assign this Agreement to a
successor in interest in connection with a merger, sale of substantially all
assets, or the like; provided however, that an assignment of this Agreement to
an entity with operations, products or services outside of the industries in
which the Company is then active shall not be deemed to expand the scope of
Employee's covenant not to compete with such operations, products or services
without Employee's written consent.

     12.  Survival.  The provisions of this Agreement shall survive the
termination of the Employee's employment hereunder in accordance with their
terms.

     13.  Governing Law.  This Agreement shall be governed by, and construed and
enforced in accordance with, the laws of Texas.

     14.  Binding Upon Successors.  This Agreement shall be binding upon, and
shall inure to the benefit of, the parties hereto and their respective heirs,
legal representatives, successors and permitted assigns.

     15.  Entire Agreement.  This Agreement constitutes the entire agreement
between the Company and the Employee with respect to the terms of employment of
the Employee by the Company and supersedes all prior agreements and
understandings, whether written or oral, between them concerning such terms of
employment.

     16.  Waiver and Amendments; Cumulative Rights and Remedies.

          (a) This Agreement may be amended, modified or supplemented, and any
obligation hereunder may be waived, only by a written instrument executed by the
parties hereto.  The waiver by either party of a breach of any provision of this
Agreement shall not operate as a waiver of any subsequent breach.

          (b) No failure on the part of any party to exercise, and no delay in
exercising, any right or remedy hereunder shall operate as a waiver hereof, nor
shall any single or partial exercise of any such right or remedy by such party
preclude any other or further exercise thereof or the exercise

                                       8
<PAGE>
 
of any other right or remedy. All rights and remedies hereunder are cumulative
and are in addition to all other rights and remedies provided by law, agreement
or otherwise.

          (c) The Employee's obligations to the Company and the Company's rights
and remedies hereunder are in addition to all other obligations of the Employee
and rights and remedies of the Company created pursuant to any other agreement.

     17.  Construction.  Each party to this Agreement has had the opportunity to
review this Agreement with legal counsel.  This Agreement shall not be construed
or interpreted against any party on the basis that such party drafted or
authored a particular provision, parts of or the entirety of this Agreement.

     18.  Severability.  In the event that any provision or provisions of this
Agreement is held to be invalid, illegal or unenforceable by any court of law or
otherwise, the remaining provisions of this Agreement shall nevertheless
continue to be valid, legal and enforceable as though the invalid or
unenforceable parts had not been included therein.  In addition, in such event
the parties hereto shall negotiate in good faith to modify this Agreement so as
to effect the original intent of the parties as closely as possible with respect
to those provisions which were held to be invalid, illegal or unenforceable.

     IN WITNESS WHEREOF, the Company and the Employee have executed this
Agreement under seal on the date first above written.
