                                  COMMON STOCK
 
                                  -----------
   
  Group Maintenance America Corp., a Texas corporation (collectively with its
subsidiaries, the "Company"), may offer and issue from time to time up to
7,000,000 shares of common stock, par value $0.001 per share ("Common Stock"),
covered by this Prospectus in connection with business combination transactions
(each, an "Acquisition") involving its acquisition, directly or indirectly, of
businesses, securities or assets of companies doing business in the Company's
industry. The price and other terms at which the Common Stock will be offered
shall be determined by negotiations between the Company and the companies to be
directly or indirectly acquired. The Company does not expect to pay any
underwriting discounts or commissions, but it may pay finder's fees from time
to time with respect to specific acquisitions. Any person receiving such fees
may be deemed to be an underwriter within the meaning of the Securities Act of
1933, as amended (the "Securities Act"). The Company will pay all expenses of
this Offering.     
   
  As of March 31, 1998, 23,297,410 shares of the Common Stock were issued and
outstanding. The Common Stock is traded on the New York Stock Exchange under
the symbol "MAK." On April 29, 1998, the last reported sales price of the
Common Stock on the New York Stock Exchange was $15 13/16 per share.     
 
  Persons receiving shares of the Common Stock offered hereby may be
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
144 under the Securities Act will apply to resales of those shares by
affiliates of the businesses the Company acquires for a period of one year from
the date of acquisition of the shares of Common Stock (or such shorter period
as the Securities and Exchange Commission may prescribe).

                               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
GroupMAC subsidiaries, and references to pro forma financial information of the
Company or combined financial information of any group of its operating units
refer to a year ending December 31 of the relevant year. Upon completion of the
IPO on November 13, 1997, the Company's fiscal year was changed to the calendar
year.     
 
                                  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 customers. Since inception, the Company
has acquired 36 platform companies and has executed definitive agreements to
acquire two additional platform companies having $509.3 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 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, and its
telephone number is (713) 860-0100.
 
                                  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."
       
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."     
 
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     
 
                                       5
<PAGE>
 
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 March 31, 1998, the executive officers, directors and certain founding
shareholders of the Company will beneficially own in the aggregate
approximately 25% 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 March 31, 1998, 23,297,410 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 3.3
million shares in connection with the acquisition of the Post Offering
Companies. 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,     
 
                                       6
<PAGE>
 
   
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 1.4 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 an additional 12.7
million shares will become available for resale pursuant to Rule 144 in the
second quarter of 1998. 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 3.2 million shares of Common Stock, of which only warrants
and options to purchase approximately 0.7 million shares are exercisable
within 60 days after the date of this Prospectus. The Company intends to
register substantially all the shares subject to these options and warrants
under the Securities Act for public resale.     
 
  The Company, its directors and executive officers and certain other
shareholders have agreed not to offer or sell any shares until May 6, 1998
without the prior written consent of The Robinson-Humphrey Company, LLC,
except (A) that the Company may issue Common Stock in connection with
acquisitions generally, and pursuant to the exercise of stock options which
are either (i) outstanding on the date of the IPO, (ii) issued under the
Company's 1997 Stock Awards Plan or (iii) issued under the Company's stock
option plan for non-management employees, and (B) that such directors,
executive officers and shareholders may sell Common Stock pursuant to a
cashless exercise of such stock options or make a bona fide gift of Common
Stock provided the donee agrees to be bound by the terms of the donor's lockup
agreement.
 
  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 the $75 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 Company by means
of a tender offer, business combination, proxy contest or otherwise. These
provisions include
 
                                       7
<PAGE>
 
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 the accounts receivable and inventory of
the Company and its material subsidiaries and all the capital stock 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,"

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.

                                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 Bank Credit Agreement restricts the payment of
dividends. See "Description of Bank 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 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 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-Offering Companies") purchased during June and July
1997 and 13 additional companies (the "Offering Acquisition Companies" and,
together with Airtron and the Pre-Offering Companies, the "GroupMAC
Companies") purchased concurrently with the IPO and (ii) the effects of
certain pro forma adjustments to the historical financial statements of the
GroupMAC Companies and Post-Offering 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
January 1, 1997, 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 new installation services
and maintenance, repair and replacement services for HVAC, plumbing,
electrical and other systems to residential and commercial customers.
Approximately 55% of the Company's combined 1997 revenues of $329.0 million
were derived from new installation services and 45% 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, 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 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 36.2% 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 20.3% 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 21.2% for the combined twelve months ended December 31, 1997. The
company primarily providing HVAC services in the residential new installation
market had a gross margin of 28.2%, which was somewhat offset by the companies
providing primarily plumbing service to this market at gross margins ranging
from 11.1% to 15.0%. 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 believes that it will, and in certain cases has already 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
will be 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 $20.4 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 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-Offering 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
Offering Acquisition Companies through a combination of cash and Common Stock
of the Company.

 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-Offering Companies in June and July of 1997 and
the acquisitions of the Offering Acquisition 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
 
                                      14
<PAGE>
 
profit was primarily attributable to the acquisitions of the Pre-Offering
Companies in June and July of 1997, the acquisitions of the Offering
Acquisition 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 GroupMAC 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-
Offering 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.
          
 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.
 
  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
 
                                      15
<PAGE>
 
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.

  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.
 
 Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
  Revenues. Revenues increased $6.0 million, or 15.2%, from $39.5 million for
the year ended December 31, 1994 to $45.5 million for the year ended December
31, 1995. The increase in revenues was attributable to a $1.2 million, or
10.5%, increase in revenues from Service and Maintenance operations, a $1.9
million, or 27.8%, increase in revenues from the company's Special Projects
and Tenant Improvement operations, and a $2.9 million, or 12.6%, increase in
revenues from installation operations, including design and build projects,
retrofits and remodeling. The broad-based increase in revenues was primarily
volume driven and attributable to generally increasing activity in the Seattle
area, the Company's principal market, and continued efforts to increase the
underlying base of service and maintenance business.
 
  Gross Profit. Gross profit increased $1.3 million, or 17.8%, from $7.3
million for the year ended December 31, 1994 to $8.6 million for the year
ended December 31, 1995. Gross margin increased from 18.4% to 18.9% for the
years ending December 31, 1994 and 1995, respectively.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $1.2 million, or 19.7%, from $6.1 million
for the year ended December 31, 1994 to $7.3 million for the year ended
December 31, 1995. The increase was attributable generally to the higher level
of revenues and an approximate $200,000 increase relating to the initial
stages of the aforementioned job cost and accounting software conversion and
other management information system processes and infrastructure that
continued into 1996. As a percentage of revenues, selling, general and
administrative expenses increased from 15.4% to 16.2% for the years ending
1994 and 1995, respectively.

 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

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
starts generated from existing customers and increased market penetration.

for the year ended December 31, 1995 to $4.0 million for the year ended

the year ended December 31, 1994 to $35.2 million for the year ended December

million for the year ended December 31, 1994 to $3.4 million for the year

expansion in plumbing new installations from more efficient production.

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

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.

the year ended March 31, 1995 to $22.7 million for the year ended March 31,

higher level of new home construction in the Dallas and Fort Worth
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,

system. As a percentage of revenues, selling, general and administrative
expenses increased slightly from 10.6% to 10.9%.

the six months ended June 30, 1996 to $24.9 million for the six months ended
June 30, 1997. The increase in revenues was primarily volume driven and
attributable to expansion of Central Carolina's commercial service and
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.

administrative expenses increased $195,000, or 2.4%, from $8.1 million for the

  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.
 
                                      22
<PAGE>
 
   
  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 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.
 
 Unaudited Fiscal 1995 Compared to Unaudited Fiscal 1994
 
  Revenues. Revenues increased $4.7 million, or 12.2%, from $38.5 million in
fiscal 1994 to $43.2 million in fiscal 1995. The increase in revenues was
primarily volume driven and attributable to incremental revenues from an
acquisition made by A-ABC in late 1994, the expansion of the customer base at
Central Carolina to include the commercial sector and an increased emphasis on
the selling of service agreements and a higher level of replacement revenues
at Van's.
 
  Gross Profit. Gross profit increased $2.6 million, or 19.8%, from $13.1
million in fiscal 1994 to $15.7 million in fiscal 1995. The increase in gross
profits was primarily attributable to the expanded revenue volumes. Gross
margin increased from 34.0% to 36.3% for fiscal years 1994 and 1995,
respectively.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $2.8 million, or 24.6%, from $11.4 million
in fiscal 1994 to $14.2 million in fiscal 1995. As a percentage of revenues,
selling, general and administrative expenses increased from 29.7% to 32.9% due
to incremental overhead at the company acquired in late 1994 by A-ABC,
incremental owners' compensation of $378,000 across the residential service
companies and an overall increase in infrastructure to keep pace with the
internal growth at each company within the group.

fiscal 1996 were $5.3 million and income from operations was $585,000.
Southeast Mechanical is headquartered in Hollywood, Florida.
 
  Yale Incorporated ("Yale") was founded in 1939 and provides HVAC services to
commercial customers throughout Minnesota. Yale's revenues for fiscal 1996
were $10.1 million and income from operations was $405,000. Yale is
headquartered in Minneapolis, Minnesota.
 
RESULTS OF OPERATIONS--OTHER COMMERCIAL SERVICE COMPANIES
 
  The GroupMAC Companies included in the Other Commercial Services Companies
derive a majority of their revenues from commercial new installation and
maintenance, repair and replacement services. In the aggregate, these nine
companies derive 96% of their revenue from commercial services and 4% of their
revenues from residential services. The following table sets forth certain
unaudited financial data for the periods indicated (dollars in thousands).

  For a discussion of periods subsequent to June 30, 1997, see "--Results of
Operations--GroupMAC and Subsidiaries."     
 
 Unaudited Six Months Ended June 30, 1997 Compared to Unaudited 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.
 
 Unaudited Fiscal 1996 Compared to Unaudited 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.
 
 Unaudited Fiscal 1995 Compared to Unaudited Fiscal 1994
 
  Revenues. Revenues increased $5.3 million, or 16.0%, from $33.2 million in
fiscal 1994 to $38.5 million in fiscal 1995. The increase in revenues was
primarily volume driven and attributable to an increase in design and build
jobs at Yale and Mechanical and an increase in service agreement volumes at
Linford.
 
  Gross Profit. Gross profit increased $1.5 million, or 16.0%, from $9.4
million in fiscal 1994 to $10.9 million in fiscal 1995. The increase in gross
profit was primarily attributable to a $2.0 million increase in revenues at
Linford at slightly higher margins, volume increases at Yale and Mechanical
and gross margin expansion at Charlie's and Arkansas Mechanical. As a
percentage of revenues, gross margin declined slightly from 28.4% in fiscal
1994 to 28.2% in fiscal 1995.
 
                                      25

  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $1.4 million, or 18.2%, from $7.7 million in
fiscal 1994 to $9.1 million in fiscal 1995. As a percentage of revenues,
selling, general and administrative expenses increased from 23.1% to 23.7% due
primarily to an increase in owners' compensation of $503,000 and personnel
additions necessary to adequately manage the revenue growth at Linford.
   
RESULTS OF OPERATIONS--PRO FORMA     
   
  During 1998, GroupMAC acquired 15 platform companies and executed definitive
agreements to acquire two additional platform companies (the "Post-Offering
Companies" and, together with the GroupMAC Companies, the "GroupMAC Pro Forma
Combined Companies"). The following table sets forth certain unaudited pro
forma financial data for the twelve month period ended December 31, 1997:

  The acquisition of the Post-Offering Companies added $180.3 million of
revenues bringing the total pro forma revenues for the GroupMAC Pro Forma
Combined Companies to $509.3 million for the twelve months ended December 31,
1997. This resulted in the Company decreasing its dependence on new
installation business from 55% of total revenues to 50%. The Post-Offering

  The Company's diversified business mix is reflected to varying degrees in
its gross margin. The Company's businesses performing primarily maintenance,
repair and replacement services in the residential markets tend to have higher
margins than businesses providing similar services to the commercial markets.
The addition of the Post-Offering Companies increase the Company's pro forma
gross profit margin from 23.6% to 23.8%. This increase was primarily
attributable the addition of a commercial electric company with a gross profit
margin of 33.4% and the addition of a commercial service company with a gross
profit margin of 25.1%. These increases were partially offset by the
acquisition of a commercial mechanical company with a gross profit margin of
15.1% and a commercial HVAC, electrical and control systems services company
with a gross profit margin of 22.2%.     
   
  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     
 
                                      26
<PAGE>
 
   
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
 
  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.
 
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 ten months ended December 31, 1997 or the years
ended February 28, 1997 or February 29, 1996.
 
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-Offering Company
and the Offering Acquisition 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 the then outstanding
preferred stock and $11.9 million for general corporate purposes including
working capital, final consideration settlements related to the GroupMAC
Companies and acquisitions consummated in 1998 to date.     
 
  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.
 
                                      27

  On December 11, 1997, the Company entered into a three year agreement with
Texas Commerce Bank National Association, (now Chase Bank of Texas National
Association) as Agent, and four other banks to provide a revolving credit
facility (the "Credit Agreement") with an initial borrowing capacity of up to
$75.0 million. Under this 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 other indebtedness in
relation to consolidated shareholders' equity and (vi) a minimum amount of
consolidated net worth. The Company is presently in compliance with those
covenants. The Credit Agreement matures on December 11, 2000. No borrowings
existed under this facility as of December 31, 1997.
 
  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,
capital expenditures aggregated $2.0 million. 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 ten months ended December 31, 1997 and the years ended February 28,
1997 and February 29, 1996, the Company generated $4.4 million, $3.7 million
and $4.0 million in cash from operating activities, respectively. 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 twelve
months 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 twelve months 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 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. The cash impact of investing activities for the
twelve months ended February 28, 1997 and February 29, 1996 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. The cash impact of financing activities for
the twelve months ended February 28, 1997 and February 29, 1996 was not
significant.
   
  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 GroupMAC 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 quarter of 1998, the Company
completed the acquisition of 15 platform companies that will be accounted for
as purchases. The combined annual revenues of these companies were $151.7
million. Total consideration paid was $68.3 million, which included cash
payments of $36.7 million, $0.8 million of subordinated convertible debt and
2.5 million shares of Common Stock. 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. As of March
27, 1998, the funds available through the Credit Agreement totaled $55.2
million, subject to the maintenance of financial ratios and covenants.     
 
                                      28

  The Company has signed definitive agreements to purchase two platform
companies with combined annual revenues of $28.5 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.     
 
  The Company intends to aggressively pursue acquisition opportunities.
Management believes that funds provided by operations, together with funds
available under the Credit Agreement, will be adequate 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 Financial Accounting Standards Board (the "FASB") issued
SFAS No. 130, Reporting Comprehensive Income, which the Company is required to
adopt for annual periods beginning after December 15, 1997. SFAS No. 130
establishes standards for reporting and display of comprehensive income and
its components in a full set of general-purpose financial statements. It is
expected that this statement will not significantly affect the Company's
financial statements, as the Company does not have significant transactions
and other events from non-owner sources that affect equity.     
 
  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 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 GroupMAC 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 36
platform companies in 44 cities in 21 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 GroupMAC
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 the then outstanding preferred stock and $11.9 million for
general corporate purposes including working capital, final consideration
settlements related to the GroupMAC 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.

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 random 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 85 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 proposes to develop (initially for its
subsidiaries, but ultimately for delivery to the market     
 
                                      34
<PAGE>
 
through licensed affiliates developed by Callahan Roach and USA) market-
leading 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. For the ten months ended December 31, 1997, advertising and
marketing expenditures represented 1.2% of the Company's combined revenue.
 
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 December 31, 1997, the Company had approximately 2,800 full and part-
time employees, of whom approximately 1,900 are installation/service
technicians. In the course of performing installation work, the Company may
utilize the services of subcontractors. Approximately 500 employees (in four
of the commercial subsidiaries) are members of unions and work under
collective bargaining agreements. The collective bargaining agreements have
expiration dates between April 1998 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 ten month
period ended December 31, 1997 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
    Common Stock was not publicly traded on the date of each grant, this
    presentation assumes the exercise price of these options equaled the fair
    market value on the date of grant.     
   
(3) The dollar amounts in these columns were calculated on the basis of the
    indicated rates of appreciation in the value of the Common Stock,
    compounded annually from the fair market value (or assumed fair market
    value) on the grant date, from the grant date to the end of the option
    term and, therefore, are not intended to forecast possible future
    appreciation.

    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.

  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.

INCENTIVE BONUS PROGRAM
   
  The Company has 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

                          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. Mr.
Sigmund will receive a portion of the contingent consideration payable to the
former shareholders of MacDonald-Miller based on the operating results of
MacDonald-Miller for the 12 month period ended December 31, 1997. The Company
estimates that such payments will be approximately $763,700. 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.

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 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 $75 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 the Company and its
Material Subsidiaries, including any future 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 Bank 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 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); and (iv) a minimum Consolidated Net Worth (as
defined in the Credit Agreement). Changes in generally accepted accounting
principles that materially affect financial covenants may result in
modifications to the financial covenants with the view to placing the
covenants on the same economic basis as before the change in generally
accepted accounting principles.     
 
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 March 31, 1998, the Company had outstanding 23,297,410 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 9.4 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. The approximately 3.3 million shares issued or to be issued
in connection with the acquisition of the Post-Offering 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 addition, certain of the Company's directors, executive officers and
principal shareholders, who hold an aggregate of approximately 3.6 million
shares of Common Stock, have entered into lock-up agreements with the
Representatives of the Underwriters. These persons have agreed not to offer,
sell, contract to sell, grant any option with respect to, pledge, hypothecate
or otherwise dispose of, any shares of Common Stock owned by them until May 6,
1998 without the prior written consent of The Robinson-Humphrey Company, LLC.
All such approximately 3.6 million shares will become available for sale on
May 6, 1998 upon expiration of these lock-up agreements, subject to compliance
with Rule 144 promulgated under the Securities Act. Furthermore, the former
shareholders of the Pre-Offering Companies and most of the shareholders of the
Offering Acquisition Companies, who collectively hold approximately 9 million
shares of Common Stock, have entered into Stock Transfer Restriction
Agreements that impose restrictions on the transferability of their shares.
See "--Transfer Restrictions."     
   
  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 1.4 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 an additional 12.7 million shares will become
available for resale pursuant to Rule 144 in the second quarter of 1998. 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 3.2 million shares of Common Stock,
approximately 0.7 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 under the Stock Awards Plan and the stock
option plan for nonmanagement employees. 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,
 
                                      55
<PAGE>
 
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 GroupMAC Companies and
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;
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 12,472,525 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.
 
                                      56
<PAGE>
 
   
  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 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.

  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 (the "Pre-Offering Companies"),
(ii) 13 companies acquired in connection with the IPO (the "Offering
Acquisition Companies") and (iii) 15 platform companies acquired subsequent to
December 31, 1997 and two additional platform companies subject to executed
definitive acquisition agreements (the "Post-Offering Companies" and together
with Airtron, the Pre-Offering Companies and the Offering Acquisition
Companies, the "GroupMAC Pro Forma Combined Companies"). The Post-Offering
Companies are as follows:

*GroupMAC has executed definitive agreements to acquire these companies.     
          
  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 Post-
Offering Companies, as if these acquisitions had occurred on December 31,
1997. The accompanying unaudited pro forma statement of operations of the
Company combines the historical statements of operations of the Company and
the statements of operations of the acquisitions as if such acquisitions had
occurred on January 1, 1997.     
   
  GroupMAC has preliminarily 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 Pro Forma Combined Companies have agreed
prospectively to reductions in salary, bonuses and benefits, these reductions
have been reflected in     
 
                                      F-4
<PAGE>
 
   
the 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-Offering and Offering
Acquisition Companies from January 1, 1997 to the dates of the acquisitions
were combined with the Company and the Post-Offering 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.     
 
2. ACQUISITIONS:
   
  The acquisitions of the Pre-Offering 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 December 31, 1997 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
Offering Acquisition Companies and the Post-Offering Companies was provided by
proceeds from the IPO and borrowings under a credit agreement dated December
11, 1997 (the "Credit Agreement"). The Credit Agreement is more fully
described in Note 7 to the GroupMAC and subsidiaries consolidated financial
statements and notes thereto included elsewhere herein.     
   
  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-Offering Companies and (d)
shares of Common Stock to the shareholders of the Pre-Offering, Offering
Acquisition and Post-Offering 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 Post-Offering Companies, the value of the Common Stock is
determined using an estimated weighted average fair value of $12.32 per share,
which represents a discount rate of 20% from the weighted average stock price
of $15.40 at the respective dates of acquisition due primarily to restrictions
on the sale and transferability of such shares. The restrictions are created
by the limitations on future sales caused by existing securities laws, and an
additional 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.     
   
  The total estimated purchase price of $188.7 million for the GroupMAC Pro
Forma Combined Companies (excluding Airtron, the accounting acquirer) is
comprised of (a) cash of $92.8 million, (b) Subordinated Debt of $0.8 million,
(c) Preferred Stock of $4.4 million and (d) Common Stock of $90.7 million.

    NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS--(CONTINUED)
   
  The estimated purchase price and related allocations of the excess purchase
price for the Post-Offering 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 Post-Offering
Companies (representing $20.2 million) will approximate fair value. This
results in an allocation to goodwill of approximately $69.8 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 COMBINED STATEMENT OF OPERATIONS ADJUSTMENTS:     
   
  a) Reflects the prospective reduction in salaries, bonuses and benefits to
the owners of the acquired businesses 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 of each of the acquired businesses amounted to
$22.0 million for the periods presented. The contractually agreed upon
compensation and benefits for these same businesses, on a going forward basis,
amount to $5.7 million for the periods presented. The difference between these
amounts equates to $16.3 million and is reflected as a pro forma adjustment.
       
  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.     
   
  c) Reflects the elimination of historical interest expense related to the
Original Credit Agreement and the assumed debt of the Pre-Offering and the
Offering Acquisition Companies resulting from the payoff of such debt with the
proceeds of the IPO. Offsetting this reduction is interest expense related to
borrowings under the Credit Agreement to fund the cash portion of the purchase
price and the assumption of debt related to the Post-Offering Companies,
interest related to the Subordinated Debt discussed in Note 3e and interest
related to the notes issued to fund the S Corporation distributions discussed
in Note 3a.     
   
  d) Reflects the reduction to historical interest income earned on the IPO
proceeds assumed to be used for the acquisition of the Post-Offering
Companies.     
          
  e) Reflects the incremental provision for federal and state income taxes
relating to the compensation differential and other pro forma adjustments
discussed in this Note 4 as well as income taxes on S Corporation earnings.

                         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

                         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

notice from the Company, but in no event later than October 24, 1998.
Subsequent to April 30, 1997, an additional 1.658 million shares have been
purchased under the Subscription Agreement.
 
PREFERRED STOCK
 
  The Company is authorized to issue up to 50 million shares of preferred
stock, par value $.001 per share, in one or more series. As of December 31,
1996 and April 30, 1997, none were outstanding.

  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:

The Board of Directors
Group Maintenance America Corp. and Subsidiaries:
 
  We have audited the accompanying consolidated balance sheets of Group
Maintenance America Corp. and Subsidiaries as of December 31, 1997 and
February 28, 1997 and the related consolidated statements of operations,
shareholders' equity and cash flows for the ten months ended December 31, 1997
and the years ended February 28, 1997 and February 29, 1996. These
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
Maintenance America Corp. and Subsidiaries as of December 31, 1997 and
February 28, 1997 and the results of their operations and their cash flows for
the ten months endedDecember 31, 1997 and the years ended February 28, 1997
and February 29, 1996, in conformity with generally accepted accounting
principles.

               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-Offering 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 "Offering Acquisition
Companies" and, together with Airtron and the Pre-Offering 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.

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

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-Offering 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 Offering
Acquisition 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).

  Pro forma adjustments included in the amounts above include compensation
differentials, 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, 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 for the
periods presented.

  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-Offering 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 Offering Acquisition 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.

  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-Offering Companies, the
Company issued warrants to purchase 514,000 shares of common stock at $17.50.

  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-Offering Company
and the Offering Acquisition Companies, $42.6 million to repay corporate
indebtedness and debt assumed in connection with the acquisition of the
GroupMAC Companies, $19.3

  Management believes it is more likely than not the Company will realize the
benefits of the net deferred tax assets. Accordingly, no valuation allowance
has been recorded as of December 31, 1997 or February 28, 1997.

</TABLE>    
 
  Total rental expense for the ten months ended December 31, 1997 and the
years ended February 28, 1997 and February 29, 1996 was approximately $2.3
million, $1.7 million and $2.0 million, respectively (including $1.2 million,
$0.6 million and $0.4 million, respectively, to related parties).
 
13. EMPLOYEE BENEFIT PLANS
 
  Several of the GroupMAC Companies maintain defined contribution employee
retirement plans, which are open to certain employees after various lengths of
service. Employee contributions and employer matching contributions occur at
different rates and the matched portions of the funds vest over a period of
years. Company contributions to these plans totaled approximately $0.4
million, $0.2 million and $0.2 million for the ten months ended December 31,
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.

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-Offering Companies"). The
combined annual revenues of the Post-Offering 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.

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.

            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.

7. NOTE PAYABLE TO BANK
 
  The note payable to bank represents the outstanding balance on a $6,000,000
revolving line of credit with interest at the bank's prime rate plus .75%. The
weighted average interest rate for December 31, 1995, 1996 and June 30, 1997
was 9.83%, 9.15% and 9.27%, respectively. The line of credit is subject to
annual renewal. The note is collateralized by receivables and inventory, and
is guaranteed by the executive officers. The Company is required under the
agreement to maintain certain financial covenants. These financial covenants
include current ratio and tangible net worth requirements, fixed asset
addition restrictions, dividend payment restrictions, and certain restrictions
regarding changes in ownership.

employees plan will be vested and exercised. The employee plan will be

 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.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 Inventories
 
  Inventories consist primarily of purchased materials and supplies.
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.

                         NOTES TO FINANCIAL STATEMENTS
                                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.

              K & N PLUMBING, HEATING AND AIR CONDITIONING, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 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.

  We have audited the accompanying combined balance sheets of Arkansas
Mechanical Services, Inc. and Mechanical Services, Inc. (collectively referred
to as the Company) as of December 31, 1996 and June 30, 1997, and the related
combined statements of operations, shareholders' equity and cash flows for the
year ended December 31, 1996 and the six months ended June 30, 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 Arkansas
Mechanical Services, Inc. and Mechanical Services, Inc. as of December 31,
1996 and June 30, 1997, and the results of its operations and its cash flows
for the year ended December 31, 1996 and the six months ended June 30, 1997 in
conformity with generally accepted accounting principles.

                    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.

                  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.

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.

The Board of Directors Central Carolina Air Conditioning Company:
 
  We have audited the accompanying balance sheets of Central Carolina Air
Conditioning Company (the Company) as of October 31, 1996 and June 30, 1997,
and the related statements of operations, shareholders' equity and cash flows
for the year ended October 31, 1996 and the eight 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 Central Carolina Air
Conditioning Company as of October 31, 1996 and June 30, 1997, and the results
of its operations and its cash flows for the year ended October 31, 1996 and

                   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.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Hallmark Air Conditioning, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Hallmark Air
Conditioning, Inc. and subsidiary (the Company) as of February 28, 1997 and
May 31, 1997, and the related consolidated statements of operations,
shareholders' equity and cash flows for the year ended February 28, 1997 and
the three months ended May 31, 1997. These 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 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Hallmark
Air Conditioning, Inc. and subsidiary as of February 28, 1997 and May 31,
1997, and the results of their operations and their cash flows for the year
ended February 28, 1997 and the three months ended May 31, 1997, in conformity
with generally accepted accounting principles.

 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.

                  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

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

                         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.

<PAGE>
 
                      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.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors Willis Refrigeration, Air Conditioning & Heating, Inc.:
 
  We have audited the accompanying balance sheets of Willis Refrigeration, Air
Conditioning & Heating, Inc. (the Company) as of March 31, 1997 and June 30,
1997, and the related statements of operations, shareholders' equity and cash
flows for the year ended March 31, 1997 and the three 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 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 Willis Refrigeration, Air
Conditioning & Heating, Inc. as of March 31, 1997 and June 30, 1997, and the
results of its operations and its cash flows for the year ended March 31, 1997
and the three months ended June 30, 1997 in conformity with generally accepted
accounting principles.

                         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.

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.

  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

                         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-161

                               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.

                       INDEPENDENT AUDITORS' REPORT     
   
The Board of Directors     
   
Premex, Inc.     
   
  We have audited the accompanying consolidated balance sheet of Premex, Inc.
and Subsidiary (the Company) as of March 31, 1998, and the related
consolidated statements of operations, shareholders' equity and cash flows for
the year then ended. These 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 audit.     
   
  We conducted our audit 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 audit provides 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 Premex,
Inc. and Subsidiary as of March 31, 1998, and the results of their operations
and their cash flows for the year then ended in conformity with generally
accepted accounting principles.

                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.

         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.

Premex, Inc. ("Commercial Air"). Hungerford, MIINC and Commercial Air are
included in the unaudited supplemental pro forma financial information as they
are considered significant business acquisitions. This supplemental pro forma
financial information gives no consideration to the pro forma effect of the
Company's acquisition of the other GroupMAC Companies during 1997 and 1998.
See "Unaudited Pro Forma Combined Financial Statements," included elsewhere
herein.     
       
       
          
  The above acquisitions of the acquisitions were accounted for under the
purchase method of accounting. This unaudited supplemental pro forma financial
information is based on the historical financial statements of the acquired
businesses and estimates and assumptions set forth below and in the notes to
the unaudited supplemental pro forma financial information.     
   
  The unaudited supplemental pro forma balance sheet combines the historical
consolidated balance sheet of the Company and the balance sheets of
Hungerford, MIINC and Commercial Air, as if these acquisitions had occurred on
December 31, 1997. The accompanying unaudited supplemental pro forma statement
of operations combines the historical statement of operations of the Company
and the statements of operations of Hungerford, MIINC and Commercial Air as if
such acquisitions had occurred on January 1, 1997.     
   
  GroupMAC has preliminarily analyzed the savings that it expects to realize
from reductions in salaries and certain benefits to the owners. To the extent
the owners of Hungerford, MIINC and Commercial Air have agreed prospectively
to reductions in salary, bonuses and benefits, these reductions have been
reflected in the unaudited supplemental pro forma statement 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 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. The pro forma 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
results may not be indicative of or comparable to future performance. The
unaudited supplemental pro forma financial information 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 SUPPLEMENTAL PRO FORMA FINANCIAL INFORMATION     
   
1. BACKGROUND:     
   
  The historical results of operations for the Company were combined with the
results of operations of Hungerford and MIINC for the twelve months ended
December 31, 1997 and Commercial Air for the twelve months ended March 31,
1998 to determine the pro forma supplemental results of operations for the
twelve months ended December 31, 1997.     
   
2. ACQUISTIONS:     
   
  The total estimated purchase price of $41.2 million for Hungerford, MIINC
and Commercial Air is comprised of (a) cash of $22.4 million and Common Stock
of $18.8 million. In computing the estimated purchase price for accounting
purposes for Hungerford, MIINC and Commercial Air, the value of the common
stock is determined using an estimated weighted average fair value of $11.98
per share, which represents a discount rate of 20% from the weighted average
stock price of $14.97 at the respective dates of acquisition due primarily to
restrictions on the sale and transferability of such shares. The restrictions
are created by the limitations on future sales caused by existing securities
laws, and an additional contractual restriction imposed on the shares issued
in connection with the acquisition of Hungerford, MIINC and Commercial Air.
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.     
   
  The estimated purchase price and related allocations of the excess purchase
price for Hungerford, MIINC and Commercial Air are based upon management's
preliminary estimates and analysis. It is anticipated that the historical
carrying value of the assets and liabilities of Hungerford, MIINC and
Commercial Air (representing $10.0 million) will approximate fair value. This
results in an allocation to goodwill of approximately $31.2 million.
Management has not identified any other material tangible or identifiable
intangible assets to which a portion of the purchase price could reasonably by
allocated.     
   
3. UNAUDITED SUPPLEMENTAL PRO FORMA BALANCE SHEET ADJUSTMENTS:     
   
  a) Records the deferred income tax amounts associated with converting
Hungerford from a corporation taxed under Subchapter S of the Internal Revenue
Code (the Code) to a corporation taxed under Subchapter C of the Code.     
   
  b) Records the settlement of all shareholder receivables and payables with
cash at closing.     
   
  c) Records the elimination of all assets and liabilities of Hungerford,
MIINC and Commercial Air that are specifically excluded as part of the
purchase transaction.     
   
  d) Records the elimination of the historical equity accounts of Hungerford,
MIINC and Commercial Air.     
   
  e) Records the purchase of Hungerford, MIINC and Commercial Air, including
the cash and common stock consideration paid to these companies.     
   
  f) Records the retirement of debt assumed in connection with the acquisition
of Hungerford, MIINC and Commercial Air.

4. UNAUDITED SUPPLEMENTAL PRO FORMA STATEMENT OF OPERATIONS ADJUSTMENTS:
   
  a) Reflects the prospective reduction in salaries, bonuses and benefits to
the owners of the Hungerford, MIINC and Commercial Air to which they 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 of each of Hungerford, MIINC and Commercial
Air amounted to $1.7 million for the periods presented. The contractually
agreed upon compensation and benefits for these same businesses, on a going
forward basis, amount to $0.8 million. The difference between these amounts
equates to $0.9 million and is reflected as a pro forma adjustment.     
   
  b) Reflects the amortization of goodwill to be recorded as a result of the
acquisitions over a 40-year estimated life.     
   
  c) Reflects the reduction of interest expense related to the assumption and
payoff of debt related to Hungerford, MIINC and Commercial Air.     
 
  d) Reflects the incremental provision for federal and state income taxes
relating to the compensation differential and other pro forma adjustments
discussed in this Note 4 as well as income taxes on S Corporation earnings.
   
  e) Weighted average shares outstanding include the following (in thousands):

                                    PART II
 
                    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.
