ITEM 5. OTHER EVENTS
 
                                 RISK FACTORS
 
  You should carefully consider the following factors and other information
here before deciding to invest in our Company
 
 
RESTRICTIONS IN CREDIT AGREEMENT ON OUR OPERATIONS--WE MAY NOT BE ABLE TO
FINANCE FUTURE NEEDS OR ADAPT OUR BUSINESS PLANS TO CHANGES BECAUSE OF
RESTRICTIONS PLACED ON US BY OUR LENDERS.
 
  The operating and financial restrictions and covenants in our Credit
Agreement adversely affect, and any future financing agreements may also
adversely affect, and in fact limit or prohibit, our ability to finance future
operations or capital needs, to respond to changes in our business or
competitive activities, or to engage in other business activities. See
"Description of Credit Agreement." A breach of any of these restrictions or
covenants could cause a default under the Credit Agreement and in some cases
acceleration of debt under other instruments that contain cross-default or
cross-acceleration provisions. A significant portion of our indebtedness then
may become immediately due and payable. We are not certain whether we would
have, or be able to obtain, sufficient funds to make these accelerated
payments.
 
INTEGRATION OF ACQUIRED COMPANIES--ANY DELAY OR INABILITY TO INTEGRATE
BUSINESSES WE ACQUIRE COULD ADVERSELY AFFECT OUR FINANCIAL HEALTH.
 
  We have grown, and plan to continue to grow, by acquiring other companies in
our industry. Our future success is dependent on our ability to integrate our
past and future acquisitions into one enterprise with a common operating plan.
We must also monitor the performance of our acquired companies. Many of these
acquired companies must change their past operating systems such as
accounting, employment, purchasing and marketing. We may not be successful in
our efforts to integrate acquired companies or monitor their performance. If
we are unable to do so, or if we experience delays or unusual expenses in
doing so, it could have a material adverse effect on our business, financial
condition and results of operations.
 
DEPENDENCE ON ACQUISITIONS FOR GROWTH--IF OUR ACQUISITION PROGRAM STRATEGY IS
NOT ACHIEVED, OUR GROWTH WILL BE DIMINISHED.
 
  We plan to grow primarily by acquisitions. This strategy requires that we
identify acquisition targets and negotiate and close acquisitions without
disrupting our existing operations. The strategy may result in the diversion
of our time from operating matters, which may cause the loss of business and
personnel. There are also possible adverse effects on earnings resulting from
the possible loss of acquired customer bases, 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
business. Our success is dependent upon our ability to identify, acquire,
integrate and manage profitably acquired businesses. If we cannot do this, our
business and growth may be harmed.
 
CYCLICAL NATURE OF NEW INSTALLATION MARKET--DOWNTURNS IN THE CONSTRUCTION
INDUSTRY COULD CAUSE OUR REVENUES FROM INSTALLING EQUIPMENT TO DECREASE.
 
  A substantial portion of our business involves installation of mechanical
and electrical systems in newly constructed residences and
commercial/industrial facilities. Our revenues from new installations services
in the residential market is dependent upon the level of housing starts in the
areas in which we operate. The housing industry is cyclical, and our revenues
from new residential installation will be affected by the factors that affect
the housing industry. These factors include changes in employment and income
levels, the availability and cost of financing for new home buyers and general
economic conditions. The level of new commercial/industrial installation
services is also affected by changes in economic conditions and interest
rates. General downturns in housing starts or new commercial/industrial
construction in the areas in which we operate could have a material adverse
effect on our business, including its financial condition and results of
operations. See "Management's Discussions and Analysis of Financial Condition
and Results of Operations--Seasonality and Cyclicality."
 
                                       2
<PAGE>
 
AVAILABILITY OF TECHNICIANS--A SKILLED LABOR FORCE IS IMPORTANT TO OUR PLANNED
INTERNAL GROWTH.
 
  Our ability to provide high-quality mechanical and electrical services on a
timely basis requires an adequate supply of skilled technicians. Shortages of
qualified technicians sometimes occur. We cannot assure you that we will be
able to maintain an adequate skilled labor force or that our labor expenses
will not increase. A shortage of skilled labor would require us to curtail our
planned internal growth.
 
WEATHER--OUR PROFITABILITY WILL BE AFFECTED BY PROLONGED BAD WEATHER OR
SEASONAL VARIATIONS.
 
  Our business tends to be affected adversely by moderate weather patterns.
Comparatively warm winters and cool summers reduce the demand for our
maintenance, repair and replacement services. Additionally, our new
installation business is affected adversely by extremely cold weather and
large amounts of rain. As a result, we expect our revenues and operating
results to be lower in our first and fourth calendar quarters. Prolonged
weather conditions or seasonal variations may cause unpredictable fluctuations
in operating results. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Seasonality and Cyclicality."
 
COMPETITION--WE FACE COMPETITION FROM OWNER-OPERATED COMPANIES AND LARGE
PUBLIC COMPANIES AND UTILITIES FOR THE SERVICES WE PROVIDE AND FOR COMPANIES
WE MAY WANT TO ACQUIRE.
 
  The mechanical and electrical and plumbing service industries are very
competitive. These industries are served by small, owner-operated private
companies and by larger companies operating nationwide, including unregulated
affiliates of electric and gas public utilities and HVAC equipment
manufacturers, and there are few barriers to entry. Certain of the smaller
competitors have lower overhead cost structures and may be able to provide
their services at lower rates than us. Some of the larger competitors have
greater financial resources, name recognition or other competitive advantages
and may be willing to pay higher prices than we are willing to pay for the
same opportunities. Consequently, we may encounter significant competition in
our efforts to achieve our growth objectives.
 
DEPENDENCE ON KEY PERSONNEL--OUR BUSINESS MAY SUFFER IF WE DO NOT RETAIN OUR
MANAGEMENT AND THE MANAGEMENT OF ANY COMPANY WE ACQUIRE.
 
  We depend on our executive officers and senior management personnel and on
the senior management of significant businesses we acquire. Our business could
be affected adversely if these persons do not continue in their roles and we
are unable to attract and retain qualified replacements.
 
DEPENDENCE ON ADDITIONAL CAPITAL FOR FUTURE GROWTH--IF WE CANNOT USE OUR
COMMON STOCK OR RAISE CAPITAL FOR CONSIDERATION IN ACQUISITIONS, WE MAY NOT BE
ABLE TO GROW OUR BUSINESS BY ACQUISITIONS.
 
  We have financed capital expenditures and acquisitions primarily through the
issuance of equity securities, secured bank borrowings and internally
generated cash flow. We currently intend to finance future acquisitions by
using shares of our common stock for a significant portion of the
consideration to be paid. If our common stock does not maintain a sufficient
market value, or if potential acquisition candidates are otherwise unwilling
to accept our common stock as part of the consideration for the sale of their
businesses, we may be required to utilize more of our cash resources, if
available, in order to initiate and maintain our acquisition program. We
cannot assure you that we will be able to raise the additional capital
required. If we cannot do so, our growth through acquisitions may be limited.
See "Management's Decision and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
DEPENDENCE ON SUBSIDIARIES FOR CASH FLOW--WE RELY ON OUR SUBSIDIARIES FOR OUR
OPERATING FUNDS AND OUR SUBSIDIARIES HAVE NO OBLIGATION TO SUPPLY US WITH ANY
FUNDS.
 
  We conduct our operations through subsidiaries and are dependent upon our
subsidiaries to transfer to us the funds we need to operate. Each of our
subsidiaries is a distinct legal entity and has no obligation, contingent or
otherwise, to transfer funds to us. Our ability to pay obligations, and the
ability of our subsidiaries to transfer funds to us, could be restricted by
the terms of subsequent financings.
 
                                       3

OTHER FACTORS
 
  In addition to the factors described above, we may be impacted by a number
of other matters and uncertainties, including:
 
    .  potential legislation or regulatory changes,
 
    .  resolution of the Year 2000 issue,
 
    .  increases in the cost of complying with regulations, including
       environmental regulations, and
 
    .  the incurrences of losses for which we are not insured, or for which
       our insurance is not adequate.

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
GENERAL
 
  The Company derives revenues from providing maintenance, repair and
replacement and new installation services for mechanical, electrical and other
systems to residential and commercial customers. The Company's combined 1997
revenues consisted of the following (dollars in millions):
 
<TABLE>

                                                             REVENUES PERCENTAGE
                                                             -------- ----------
<S>                                                          <C>      <C>
Maintenance, repair and replacement.........................  $587.5      60%
New installation............................................   391.0      40%
                                                              ------     ---
    Total...................................................  $978.5     100%
                                                              ======     ===
</TABLE>
 
  The Company recognizes maintenance, repair and replacement revenues as the
services are performed, except for service contract revenue, which we
recognize ratably over the life of the contract. We generally account for
revenues from fixed price installation and retrofit contracts on a percentage-
of-completion basis, using the cost-to-cost method.
 
  The Company intends to make additional acquisitions across the three main
technical disciplines (HVAC, electrical and plumbing) within the residential
and commercial markets. The Company's long-term objective is to develop
maintenance, repair and replacement capabilities (both residential and
commercial) in the top 100 markets within the United States, while offering
new installation services across a more limited range of markets where new
construction in the residential and/or commercial sectors is expected to out-
pace the national average over the long term. Over time, this objective is
expected to shift revenues of the Company to an increased percentage of
service revenue.
 
  Cost of services consists primarily of components, parts and supplies
related to the Company's new installation and maintenance, repair and
replacement services, salaries and benefits of service and installation
technicians, subcontracted services, depreciation, fuel and other vehicle
expenses and equipment rentals. Selling, general and administrative expenses
consist primarily of compensation and related benefits for prior owners,
administrative salaries and benefits, advertising, office rent and utilities,
communications and professional fees.
 
  The Company's diversified business mix is reflected to varying degrees in
its gross margins. The Company's businesses performing primarily maintenance,
repair and replacement services in the residential markets tend to have higher
gross margins, averaging 32.4% for the combined twelve months ended
December 31, 1997. The combined gross margin for the GroupMAC Companies
providing primarily maintenance, repair and replacement services in the
commercial markets was 21.6% for the combined twelve months ended December 31,
1997. On average, the Company's residential new installation businesses have
lower gross margins. Such companies' combined gross margin was 21.0% for the
combined twelve months ended December 31, 1997. The companies primarily
providing HVAC services in the residential new installation market had an
average gross margin of 27.6%, which was somewhat offset by the companies
providing primarily plumbing service to this market at an average gross margin
of 12.9%. Future consolidated gross margins may vary depending on, among other
things, shifts in the business mix as well as the impact of future
acquisitions on the business mix.
 
  The Company has begun to realize savings from (i) greater volume discounts
from suppliers of components, parts and supplies; (ii) consolidation of
insurance and bonding programs; (iii) other general and administrative
expenses such as training and advertising; and (iv) the Company's ability to
borrow at lower interest rates than most, if not all, of its subsidiaries.
These savings are [partially] offset by costs related to the Company's new
corporate management, costs associated with being a public company and
integration costs.

financial statements and related notes and "Selected Historical and Pro Forma
Financial Data" included or incorporated by reference herein.

RESULTS OF OPERATIONS--GROUPMAC AND SUBSIDIARIES
 
  Effective April 30, 1997, GroupMAC entered into an Agreement and Plan of
Exchange (the "Agreement") with Airtron, in which $20.8 million in cash, 14.9
million shares of GroupMAC preferred stock and 4.7 million shares of GroupMAC
Common Stock were issued to shareholders of Airtron in exchange for all of the
then outstanding shares of Airtron. Although for legal purposes Airtron was
acquired by GroupMAC, for accounting 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 Company recorded the consideration paid to the shareholders of
GroupMAC 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 included 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. During
1997, the Company changed its fiscal year end from February 28 to December 31.
 
  During June and July 1997, the Company acquired in separate transactions 10
additional businesses 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 businesses through a combination of cash and common stock of the
Company. During the first, second and third quarters of 1998 the Company
acquired 35 additional businesses through a combination of common stock,
options to purchase common stock and cash.
 
  The following table sets forth certain financial data for the periods
indicated (dollars in thousands):

 Nine Months Ended September 30, 1998 Compared to Nine Months Ended September
30, 1997
 
  Revenues. Revenues increased $395.7 million to $477.9 million for the nine
months ended September 30, 1998 from $82.2 million for the nine months ended
September 30, 1997. Such increase in revenues included $357.6 million
attributable to the acquisition of the IPO Companies during November 1997 and
the acquisitions of the Post-IPO Companies during the nine months ended
September 30, 1998. Also contributing to the increase was a $10.0 million
increase in revenues at Airtron, which related to strong housing starts
throughout the country, particularly in the Midwestern and South Central
United States. The remaining $28.1 million increase relates to the Pre-IPO
Companies that have nine months of activity in the current year versus two to
four months of activity in the prior year.
 
  Gross Profit. Gross profit increased $90.7 million to $113.7 million for the
nine months ended September 30, 1998 from $23.0 million for the nine months
ended September 30, 1997. Such increase in gross profit included approximately
$1.5 million in materials purchases savings and $76.6 million attributable to
the
 
                                       6
<PAGE>
 
acquisitions of the IPO Companies during November 1997 and the acquisitions of
the Post-IPO Companies during the nine months ended September 30, 1998. Gross
profit at Airtron increased by $3.5 million between periods. This increase
correlated favorably with the $10.0 million revenue increase as Airtron is
operating near full capacity to accommodate housing start demand in its
geographic markets and has deployed resources to further broaden its service
base. The remaining $9.1 million increase related to the Pre-IPO Companies
that have nine months of activity in the current year versus two to four
months of activity in the prior year. Gross profit margin decreased 4.2% to
23.8% for the nine months ended September 30, 1998 compared to 28.0% for the
nine months ended September 30, 1997. The overall decrease in gross margin was
attributable to the acquisition of primarily commercial/industrial companies
in 1998 which has shifted the Company's business mix toward the lower gross
margin commercial/industrial business.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $54.7 million to $81.4 million for the nine
months ended September 30, 1998 from $26.7 million for the nine months ended
September 30, 1997. Such increase included $47.6 million attributable to the
acquisitions of the IPO Companies during November 1997 and the acquisitions of
the Post-IPO Companies during the nine months ended September 30, 1998 and
$6.7 million related to the Pre-IPO Companies that have nine months of
activity in the current year versus two to four months of activity in the
prior year. Also contributing to the increase was a $5.3 million increase in
corporate expenses representing the formation of the corporate management team
and infrastructure necessary to execute the Company's operating and
acquisition strategies and $3.4 million of goodwill amortization. Offsetting
the increases was a $7.0 million reduction in compensation expense recognized
in the prior year from the reverse acquisition of Airtron and a $1.3 million
reduction due primarily to the prospective reductions in compensation to the
former owners of Airtron. As a percentage of revenues, selling, general and
administrative expenses, excluding corporate expenses, goodwill amortization
and the 1997 non-recurring compensation expense, decreased to 14.8% for the
nine months ended September 30, 1998 from 21.4% for the nine months ended
September 30, 1997, respectively, due primarily to achieving lower selling and
administrative expense margins within the Founding Companies and acquiring a
higher mix of commercial companies which tend to have lower selling and
administrative expense structures. When including corporate expenses and
goodwill amortization, but excluding the non-recurring compensation expense of
$7.0 million related to the reverse acquisition, selling, general and
administrative expenses as a percentage of revenue decreased to 17.0% for the
nine months ended September 30, 1998 from 24.0% for the nine months ended
September 30, 1997.
 
  Net Interest. Net interest increased $1.8 million during the nine months
ended September 30, 1998 compared to the same period of the prior year. Such
increase was attributable to a higher level of borrowings under the Company's
credit facility to finance the Company's aggressive acquisition program during
1998. See "Liquidity and Capital Resources."
 
  Income Tax Provision. The income tax provision increased $12.0 million to
$13.2 million for the nine months ended September 30, 1998 from $1.2 million
for the nine months ended September 30, 1997. This increase corresponds with
the pretax income increase of $27.3 million between periods after adding back
the $7.0 million of compensation expense related to the reverse acquisition of
Airtron. The effective tax rate for the nine months ended September 30, 1998
was 44.2% compared to 43.2% for the nine months ended September 30, 1997 after
adding back the $7.0 million of compensation expense related to the reverse
acquisition of Airtron. This increase results primarily from the increase in
non-deductible goodwill amortization of $3.4 million in the nine months ended
September 30, 1998.
 
 Ten Months Ended December 31, 1997 Compared to Twelve Months Ended February
28, 1997
 
  Revenues. Revenues increased $56.6 million, or 69.1%, to $138.5 million for
the ten months ended December 31, 1997 from $81.9 million for the twelve
months ended February 28, 1997. The increase in revenues was attributable to
the acquisitions of the Pre-IPO Companies in June and July of 1997 and the
acquisitions of the IPO Companies during November 1997. The increase in
revenues was partially offset as the period ended December 31, 1997 included
ten months while the period ended February 28, 1997 included twelve months.

million for the ten months ended December 31, 1997 from $23.4 million for the
twelve months ended February 28, 1997. The increase in gross profit was
primarily attributable to the acquisitions of the Pre-IPO Companies in June
and July of 1997, the acquisitions of the IPO Companies during November 1997
and lower material costs at Airtron. The increase in gross profit was
partially offset as the period ended December 31, 1997 included ten months
while the period ended February 28, 1997 included twelve months. Gross profit
margin decreased 2.0% for the ten months ended December 31, 1997 compared to
the twelve months ended February 28, 1997 because certain of the Founding
Companies' gross profit margins were considerably lower than those achieved at
Airtron.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $16.7 million, or 84.3%, to $36.5 million
for the ten months ended December 31, 1997 from $19.8 million for the twelve
months ended February 28, 1997. Such increase was primarily attributable to
(i) a $7.0 million non-recurring non-cash compensation charge related to the
reverse acquisition of GroupMAC in May 1997, (ii) a $0.2 million non-
recurring, non-cash compensation charge related to the issuance of management
shares and options, (iii) the aforementioned acquisitions and (iv) a $4.1
million increase in corporate expenses representing the formation of the
corporate management team and infrastructure necessary to execute the
Company's operating and acquisition strategies. As a percentage of revenues,
selling, general and administrative expenses, excluding the aforementioned
items, decreased to 17.5% for the ten months ended December 31, 1997 from
24.1% for the twelve months ended February 28, 1997, respectively, due
primarily to prospective reductions in compensation to former owners, to which
they agreed. These reductions in salaries are in accordance with the terms of
their employment agreements.
 
  Net Interest. Net interest was an expense of $1.1 million for the ten months
ended December 31, 1997. For the twelve months ended February 28, 1997, net
interest income was $0.1 million. Interest charges increased during the ten
months ended December 31, 1997 due to borrowings under the Company's credit
facilities to fund the cash portion of the acquisition of Airtron and the Pre-
IPO Companies. See "Liquidity and Capital Resources."
 
  Income Tax Provision. The income tax provision increased $1.2 million, or
75.0%, to $2.8 million for the ten months ended December 31, 1997 from $1.6
million for the twelve months ended February 28, 1997 while pre-tax income
decreased $4.7 million. Excluding the effect of the $7.0 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 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.

 Nine Months Ended September 30, 1997 Compared to Nine Months Ended
 September 30, 1996
 
  Revenues. Revenues increased $2.4 million, or 4.6%, from $52.2 million for
the nine months ended September 30, 1996 to $54.6 million for the nine months
ended September 30, 1997. The increase in revenues was attributable to
continuing strength in the company's Northwest commercial markets, principally
Seattle, Washington and Portland, Oregon, including a $20 million contract
with a large software company to be completed in 1997, an increase in revenues
from the company's Special Projects and Tenant Improvement operations, and an
increase in revenues from the company's Commercial Service operations.
 
  Gross Profit. Gross Profit increased $1.2 million, or 17.1%, from $7.0
million for the nine months ended September 30, 1996 to $8.2 million for the
nine months ended September 30, 1997. Gross margin increased from 13.4% for
the first nine months of 1996 to 15.0% for the same period of 1997. The gross
profit increase was attributable principally to higher volume and realized
gross margins in the MacDonald-Miller's Special Projects and Tenant
Improvement operations.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $0.6 million, or 10.7%, from $5.6 million
for the nine months ended September 30, 1996 to $6.2 million for the nine
months ended September 30, 1997. Both the dollar and percentage of revenue
changes were attributable to the higher revenue levels in 1997 compared to
1996. As a percentage of revenues, selling, general and administrative
expenses increased slightly from 10.7% for the nine months of 1996 to 11.5%
for the same period of 1997.

 Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
  Revenues. Revenues increased $20.6 million, or 45.3%, from $45.5 million for
the year ended December 31, 1995 to $66.1 million for the year ended December
31, 1996. The increase in revenues was attributable to a 15%, or $1.6 million,
increase in revenues from Service and Maintenance operations, and a 23%, or
$2.0 million, increase in revenues from the company's Special Projects and
Tenant Improvement operations. The $17 million balance of the increase was
attributable to contracted design and build projects, HVAC system retrofits
and remodels, lighting energy retrofits and technical services, together
representing a revenue increase of 65.4% over 1995. This increase was
primarily volume driven and directly related to the company's effort to
increase its market presence in the Seattle, Washington and Portland, Oregon
metropolitan areas, fueled by continued strength of commercial activity in the
Northwest.
 
  Gross Profit. Gross profit increased $1.1 million, or 12.8%, from $8.6
million for the year ended December 31, 1995 to $9.7 million for the year
ended December 31, 1996. Gross margin decreased from 18.9% to 14.7% due to the
acceptance of certain lower margin projects and increased direct costs related
to the rapid revenue growth experienced in 1996.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $0.3 million, or 4.1%, from $7.3 million for
the year ended December 31, 1995 to $7.6 million for the year ended December
31, 1996. The increase in these expenses was directly attributable to
incremental costs incurred to implement a job cost and accounting software
conversion and other management information systems processes and
infrastructure. As a percentage of revenues, selling, general and
administrative expenses decreased from 16.2% to 11.6% due to the increased
revenue levels.

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.

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.

administrative expenses increased $0.3 million, or 17.6%, from $1.7 million
for the nine months ended September 30, 1996 to $2.0 million for the nine
months ended September 30, 1997. The increase in selling, general and
administrative expenses was primarily due to staff additions to keep pace with
the growth of the company, increased bad debts and an increase in professional
fees. As a percentage of revenues, selling, general and administrative
expenses increased from 6.0% to 6.5% over the respective periods.
 
 Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

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

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

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

increases in operational efficiency.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $256,000, or 19.7%, from $1.3 million for
the six months ended June 30, 1996 to $1.6 million for the six months ended
June 30, 1997. The increase in selling, general and administrative expenses
was primarily attributable to additional owners' compensation expense. As a
percentage of revenues, selling, general and administrative expenses increased
from 11.4% to 13.0% for 1996 and 1997, respectively.
 
 Year Ended March 31, 1997 Compared to Year Ended March 31, 1996
 
  Revenues. Revenues increased $1.6 million, or 7.0%, from $22.7 million for
the year ended March 31, 1996 to $24.3 million for the year ended March 31,
1997. The increase in revenues was primarily volume driven and attributable to
the expansion of the Company's customer base to include several new home
builders in the Austin and Las Vegas markets.
 
  Gross Profit. Gross profit increased $1.2 million, or 50.0%, from $2.4
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.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $160,000, or 6.4%, from $2.5 million for the

  Revenues. Revenues increased $1.2 million, or 5.6%, from $21.5 million for
the year ended March 31, 1995 to $22.7 million for the year ended March 31,
1996. The increase in revenues was primarily volume driven and attributable to
the new operating facilities in Austin, Texas and Las Vegas, Nevada and a
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,
California operation and the implementation of a new management information
system. As a percentage of revenues, selling, general and administrative
expenses increased slightly from 10.6% to 10.9%.

  For a discussion of periods subsequent to June 30, 1997, see "--Results of
Operations--GroupMAC and Subsidiaries."
 
 Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996
 
  Revenues. Revenues increased $1.6 million, or 6.9%, from $23.3 million for
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.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $195,000, or 2.4%, from $8.1 million for the
six months ended June 30, 1996 to $8.3 million for the six months ended June
30, 1997. As a percentage of revenues, selling, general and administrative
expenses decreased from 34.7% to 33.2% for the six month period ended June 30,
1996 compared to the corresponding period in 1997.
 
 Fiscal 1996 Compared to Fiscal 1995
 
  Revenues. Revenues increased $5.8 million, or 13.4%, from $43.2 million in
fiscal 1995 to $49.0 million in fiscal 1996. The increase in revenues was
primarily volume driven and attributable to the continued internal
 
                                      14
<PAGE>
 
expansion of HVAC services to an appliance company acquired by A-ABC in late
1994, an acquisition made during early 1996 by Hallmark of an operation in San
Antonio and an aggressive advertising campaign at Costner. Also, revenues
increased significantly at Van's and Willis due to a higher level of
replacement sales.
 
  Gross Profit. Gross profit increased $2.6 million, or 16.6%, from $15.7
million in fiscal 1995 to $18.3 million in fiscal 1996. The increase in gross
profit was attributable to the continued internal expansion of HVAC services
at A-ABC, an acquisition by Hallmark of a high margin operation in San Antonio
and revenue increases at Costner and other higher margin companies. Gross
margin increased from 36.3% to 37.4% for fiscal 1995 and 1996, respectively.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $2.3 million, or 16.2%, from $14.2 million
in fiscal 1995 to $16.5 million in fiscal 1996. The increase in selling,
general and administrative expenses was mainly due to the acquisition of an
operation in San Antonio by Hallmark during the period, a higher level of
spending on advertising at Costner and an increase in owner compensation among
all of the residential service companies of $116,000. As a percentage of
revenues, selling, general and administrative expenses increased from 32.9% to
33.7% for fiscal 1995 and 1996, respectively.

 Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996
 
  Revenues. Revenues declined $590,000, or 2.4%, from $24.5 million for the
six months ended June 30, 1996 to $23.9 million for the six months ended June
30, 1997. The decrease in revenues was primarily volume driven and
attributable to a $2.0 million decline in revenues at Sibley which resulted
from an internal decision to discontinue a large, low margin customer
relationship. Such decline was offset by growth at Linford from incremental
service agreements and at Mechanical Services from incremental "design and
build" project work.
 
  Gross Profit. Gross profit declined $192,000, or 2.9%, from $6.9 million for
the six months ended June 30, 1996 to $6.7 million for the six months ended
June 30, 1997. The decline in gross profit primarily resulted from the
discontinuance of the customer relationship discussed above. Gross margin
remained consistent at 28.1% and 28.0% for the six month periods ended June
30, 1996 and 1997, respectively.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $494,000, or 10.6%, from $4.7 million for
the six months ended June 30, 1996 to $5.2 million for the six months ended
June 30, 1997. The increase in selling, general and administrative expenses
was primarily attributable to incremental owners' compensation and additional
personnel to support the growth in sales at Linford and an
 
                                      16
<PAGE>
 
intentional shift in business mix at Yale toward higher margin service
contract work. As a percentage of revenues, selling, general and
administrative expenses increased from 19.2% to 21.7% over the six month
periods ended June 30, 1996 and 1997, respectively.
 
 Fiscal 1996 Compared to Fiscal 1995
 
  Revenues. Revenues increased $8.0 million, or 20.8%, from $38.5 million in
fiscal 1995 to $46.5 million in fiscal 1996. The increase in revenues was
primarily volume driven and attributable to incremental service agreements at
Linford, incremental design and build projects at Mechanical Services and an
increase in maintenance, repair and replacement sales at Southeast Mechanical
and Sibley Services.
 
  Gross Profit. Gross profit increased $1.8 million, or 16.5%, from $10.9
million in fiscal 1995 to $12.7 million in fiscal 1996. The largest factor
impacting the increase in gross profit was volume growth in revenues at
Linford, although the growth was at slightly lower margins. Additionally,
significant increases in gross profit were due to rapid service revenue growth
combined with margin expansion at All Service and Yale. Gross margin decreased
slightly from 28.2% to 27.2% between fiscal 1995 and fiscal 1996.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $1.3 million, or 14.3%, from $9.1 million in
fiscal 1995 to $10.4 million in fiscal 1996. The overall increase in selling,
general and administrative expenses was due to the expansion and relocation of
facilities as well as an increase in administrative and sales personnel at
Linford. As a percentage of revenues, selling, general and administrative
expenses decreased slightly from 23.7% to 22.3% in fiscal 1996.

SEPTEMBER 30, 1997 AND 1998:
 
 Combined Nine Months Ended September 30, 1998 Compared to Combined Nine
 Months Ended September 30, 1997
 
  Revenues. Combined revenues increased $60.2 million, or 8.3%, to $783.8
million for the nine months ended September 30, 1998 from $723.6 million for
the nine months ended September 30, 1997. The increase in combined revenues
was attributable to (i) the companies that primarily provide residential new
installation services which experienced a $19.3 million increase, or 16.0%,
due to an increase in new home starts in the markets they serve, (ii)
companies that primarily provide residential maintenance, repair and
replacement services which experienced a $10.0 million increase, or 14.6%, due
to favorable weather patterns in the markets they serve and (iii) an increase
of $31.4 million, or $5.9%, from the companies that provide
commercial/industrial services primarily in the Seattle, Salt Lake City,
Baltimore, Philadelphia and Dallas markets partially offset by economic
softening in the Company's Richmond, Virginia market.
 
  Gross Profit. Combined gross profit increased $15.3 million, or 9.4%, to
$178.8 million for the nine months ended September 30, 1998 from $163.5
million for the nine months ended September 30, 1997. The increase in gross
profit was primarily attributable to the increase in combined revenues
described above. Gross profit margin increased to 22.8% for the nine months
ended September 30, 1998 compared to 22.6% for the nine months ended September
30, 1997. The increase in gross profit margin was a result of (i) overall
margin improvement at the companies that primarily provide residential new
installation services as these companies have operated near full capacity to
accommodate housing start demand in the geographic markets they serve, (ii) a
slightly higher mix of higher margin maintenance, repair and replacement
business in the residential sector from the favorable weather patterns
discussed above, and (iii) purchasing materials savings experienced in the
current year.

  Background. The Year 2000 issue refers to the inability of certain date-
sensitive computer chips, software and systems to recognize a two-digit date
field as belonging to the 21st century. Many computer software programs, as
well as certain hardware and equipment containing date sensitive data, were
structured to utilize a two-digit date field. Accordingly, these programs may
not be able to properly recognize dates in the year 2000 and later, which
could result in significant system and equipment failures. This is a
significant issue for most if not all companies, with far reaching
implications, some of which cannot be anticipated or predicted with any degree
of certainty. The Company recognizes that it must take action to ensure that
its operations will not be adversely impacted by Year 2000 software failures.
 
  The Company's State of Readiness. An initial systems survey of the GroupMAC
Companies was completed in March 1998 and revealed that several of the
Company's core business applications possess Year 2000 problems. The Company
retained an outside consulting firm to evaluate more thoroughly the extent of
the problem and to assist the Company in preparing an action plan to address
the issues in a timely manner. The evaluation project began in early July
1998.
 
  With the exception of eight recent acquisitions, the evaluation project is
substantially complete. The Company estimates that the cost of bringing the
evaluated systems into compliance is between $130,000 and $175,000, including
all software upgrade fees and implementation and expects to expense
substantially all of these costs. These costs are independent of any costs
associated with the common information system discussed below. The projected
effort for the majority of the systems includes an upgrade to recent vendor
software releases that are fully Year 2000 compliant. Management is working
with the consultant to finalize implementation planning and to develop
tracking mechanisms to ensure upgrades are completed in a timely manner.
Additionally, the Company has engaged an outside consulting firm to evaluate
and estimate the impact of Year 2000 problems on potential future acquisitions
as part of the due diligence process. As of September 30, 1998, the Company
has incurred expenses of approximately $75,000 related to the evaluation phase
of this project.

  Independent of its Year 2000 activities discussed in the previous paragraph,
the Company continues to develop a common information system throughout the
organization for its overall information needs that will be free of any Year
2000 limitations. While the Company is not dependent on the implementation of
the common information system to remedy its Year 2000 problem, it will give
priority for implementation of the common information systems to those
GroupMAC Companies where correction of the Year 2000 problem is an issue. The
Company expects to commence user-acceptance testing of the new information
system during the second quarter of 1999 with implementation to follow
immediately thereafter.
 
  The Company is completing a plan to evaluate the effect of the Year 2000
problem on the Company's most significant customers and suppliers, and thus
indirectly on the Company. This evaluation is expected to be complete by
December 31, 1998. At this time, the Company has not assessed the potential
adverse effect on the Company of the failure by any of its customers and
suppliers to be Year 2000 compliant.
 
  Embedded Technology. The Company has focused its assessments to date on the
information technology systems. These assessments indicate that, due to the
nature of the Company's operations, the non-information technology systems
(i.e. embedded technology such as microcontrollers) do not represent a
significant area of risk relative to Year 2000 readiness. The Company's
operations do not include capital intensive equipment with embedded
microcontrollers.
 
  Contingency Plan. The Company has not implemented a Year 2000 contingency
plan. As explained above, the Company has initiated action to identify and
resolve Year 2000 problems. The Company intends to develop and implement a
contingency plan in the event the Company's present course of action to solve
the Year 2000 problem should fall behind schedule.
 
SEASONALITY AND CYCLICALITY
 
  The HVAC industry is subject to seasonal variations. Specifically, the
demand for new installations is generally lower during the winter months due
to reduced construction activities during inclement weather and less use of
air conditioning during the colder months. Demand for HVAC services is
generally higher in the second and third quarters. Accordingly, the Company
expects its revenues and operating results generally will be lower in the
first and fourth quarters. Historically, the construction industry has been
highly cyclical. As a result, the Company's volume of business may be
adversely affected by declines in new installation projects in various
geographic regions of the United States.
 
INFLATION
 
  Inflation did not have a significant effect on the results of operations of
the GroupMAC Companies for the years ended February 29, 1996 or February 28,
1997, the ten months ended December 31, 1997 or the nine months ended
September 30, 1998.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  During November and December 1997, the Company completed the IPO involving
the sale of 8.3 million shares of Common Stock at a price to the public of
$14.00 per share. The net proceeds from the IPO (after deducting underwriting
discounts and commissions and offering expenses) were approximately $103.6
million. Of this amount, $29.8 million was used to pay the cash portion of the
closing consideration relating to the acquisitions of 14 businesses, $42.6
million to repay corporate indebtedness and debt assumed in connection with
the acquisition of 24 businesses, $19.3 million to retire all of the then
outstanding preferred stock and $11.9 million for general corporate purposes
including working capital and final consideration settlements related to
previous acquisitions.
 
  Historically, the Company has financed its operations and growth with
internally generated working capital and borrowings from commercial banks or
other lenders. These borrowings were generally secured by the accounts
receivable and inventory of the Company.
 
                                      19

  On June 12, 1998, the Company amended and restated its revolving credit
facility (the "Credit Agreement") to increase its borrowing capacity from
$75.0 million to $125.0 million. On October 15, 1998, the Company amended and
restated the Credit Agreement to increase its borrowing capacity from $125.0
million to $230.0 million. Under this Credit Agreement, the Company is
required to maintain (i) a minimum fixed charge coverage ratio; (ii) a maximum
ratio of total indebtedness for borrowed money to capitalization (as defined
in the Credit Agreement); (iii) a maximum ratio of debt to pro forma earnings
before interest, taxes, depreciation and amortization; (iv) a maximum amount
of other indebtedness in relation to consolidated shareholders' equity and (v)
a minimum amount of consolidated net worth. The Company is presently in
compliance with those covenants. The Credit Agreement matures on October 13,
2001.
 
  The Company entered into agreements to lock in the ten year U.S. Treasury
rates to be used to price an anticipated debt offering ("the Offering") of at
least $100 million. The Company has locked in $100 million at 5.5212%, which
the Company believes is an attractive long-term base rate. This agreement
expires on January 31, 1999.
 
  As of December 21, 1998, the ten year Treasury yield was 4.626%,
representing a potential additional pre-tax financing cost of approximately
$6.9 million if the agreements were settled as of this date. In accordance
with Statement of Financial Accounting Standards No. 80, Accounting for
Futures Contracts, this agreement is considered a hedge against rising
interest rates for an anticipated transaction considered probable that should
be recorded as deferred costs associated with the offering and amortized into
interest expense over the term of the related debt. However, if the Offering
at some point does not meet the probable of occurrence standard, a gain or
loss would be reorganized in earnings for the fair value of the instrument at
that date. It should be noted that a decline in interest rates will generally
have a positive impact on the Company's operations.
 
  The Company intends to aggressively pursue acquisition opportunities.
Management believes that the Company has viable financing alternatives to meet
the Company's anticipated requirements for acquisitions. Estimates as to
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.
 
  The Company's primary requirements for capital (other than those related to
acquisitions) consist of purchasing vehicles, inventory and supplies used in
the operation of the business. During the ten months ended December 31, 1997
and the nine months ended September 30, 1998, capital expenditures aggregated
$2.0 million and $6.6 million, respectively. The Company anticipates that its
cash flow from operations will provide cash in excess of the Company's normal
working capital needs, debt service requirements and planned capital
expenditures for property and equipment.
 
  For the years ended February 29, 1996 and February 28, 1997, the ten months
ended December 31, 1997 and the nine months ended September 30, 1998, the
Company generated $4.0 million, $3.7 million, $4.4 million and $8.4 million in
cash from operating activities, respectively. For the year ended February 29,
1996, net income, depreciation, amortization and deferred taxes generated $1.0
million, and changes in asset and liability accounts generated a net $3.0
million. For the year ended February 28, 1997, net income, depreciation,
amortization and deferred taxes generated $4.9 million, and changes in asset
and liability accounts utilized a net $1.2 million. For the ten months ended
December 31, 1997, net income, depreciation, amortization, deferred taxes and
non-cash compensation generated $7.5 million and changes in asset and
liability accounts utilized a net $3.1 million. For the nine months ended
September 30, 1998, net income, depreciation, amortization gain from sale of
property and equipment and deferred taxes generated $24.7 million, and changes
in asset and liability accounts utilized a net of $16.3 million.
 
  The cash impact of investing activities for the years ended February 29,
1996 and February 28, 1997 was not significant. For the ten months ended
December 31, 1997, the Company used $37.9 million in investing activities. The
cash expended during the ten months ended December 31, 1997 consisted of $35.8
million for acquisitions and $2.0 million for capital expenditures. For the
nine months ended September 30, 1998, the Company used $118.7 million in
investing activities. The cash expended during the nine months ended September
30, 1998 consisted of $111.1 million for acquisitions and $6.4 million for net
capital expenditures and $1.2 million for deferred acquisition costs.

  The cash impact of financing activities for the years ended February 29,
1996 and February 28, 1997 was not significant. For the ten months ended
December 31, 1997, the Company generated $54.9 million in cash from its
financing activities. These activities principally consisted of issuance of
common stock for $109.7 million and proceeds from long-term debt of $32.5
million less distributions to shareholders of $20.4 million, payments of long-
term debt of $47.7 million and retirement of preferred stock of $19.3 million.
For the nine months ended September 30, 1998, the Company generated $86.8
million in cash from its financing activities. These activities principally
consisted of proceeds from the Credit Agreement of $142.1 million, less
payments of long-term debt of $55.3 million.
 
  During the first nine months of 1998, the Company completed the acquisition
of 35 companies, which were accounted for as purchases, for approximately
$237.8 million, which includes cash payments of $126.8 million, $0.8 million
of subordinated convertible debt, $4.0 million of notes payable, 7.8 million
shares of common stock and options to purchase 0.3 million shares of common
stock. Of the total consideration, approximately $9.3 million of cash and 0.1
million shares of common stock is due to former shareholders at September 30,
1998. The Company financed the cash portion of the purchase price using (i)
remaining funds from the IPO, (ii) cash borrowed under the Credit Agreement
and (iii) internally generated funds. The combined 1997 annual revenues of
these companies were $453.2 million.
 
  From October 1, 1998 through December 31, 1998, the Company acquired four
additional platform companies with combined annual revenues of $196.3 million.
Total consideration paid or to be paid was approximately $136.8 million
consisting of cash payments of $77.6 million, $16.0 million of subordinated
debt, 4.2 million shares of common stock, options to purchase 0.1 million
shares of common stock and warrants to purchase 0.8 million shares of common
stock. These acquisitions will be accounted for as purchases. The Company
financed the cash portion of the purchase price with borrowings under the
Credit Agreement. As of December 4, 1998, the funds available under the Credit
Agreement totaled $45.1 million, subject to the maintenance of financial
ratios and covenants.
 
  The Company has registered under the Securities Act of 1933, as amended, and
has available for issuance in connection with future acquisitions
approximately 3.3 million shares of common stock.
 
  In connection with the acquisition of Trinity Contractors, Inc. ("Trinity"),
the Company paid cash and issued common stock, warrants to purchase common
stock and subordinated notes (the "Trinity Notes"). The Trinity Notes are the
direct, unsecured subordinated obligations of GroupMAC and are junior to all
other indebtedness of GroupMAC or any of its subsidiaries. The Trinity Notes
do not contain financial covenants binding on the Company or its subsidiaries,
nor will they limit the amount of indebtedness, whether senior or
subordinated, that the Company or its subsidiaries can incur. Unless prepaid
in whole or part at any time by the Company, the balance of the Trinity Notes
is due five years from the date of issuance. The Trinity Notes bear interest
at 6% per annum with an interest penalty of 3% per annum after December 31,
1999 if the Company fails to register under the Securities Act certain shares
of common stock issued in connection with the acquisition. Holders of the
Trinity Notes have a one-time option to require the Company to repurchase the
Trinity Notes (the "Put Option") in the event the Company issues $50,000,000
or more in principal amount of debt that is either (1) registered under the
Securities Act and sold to the public or (2) sold to qualified institutional
buyers. An event of default under the Trinity Notes will occur if (1) the
Company fails to pay principal or interest on the Trinity Notes when due, (2)
the Company fails to comply with the Put Option or (3) certain events occur
relating to the bankruptcy, insolvency or reorganization of the Company. A
default under other indebtedness of the Company is not an event of default
under the Trinity Notes. If an event of default occurs under the Trinity
Notes, the holders of Trinity Notes may only accelerate payment after
receiving the consent of holders of the Company's debt that is senior to the
Trinity Notes. The Company has the right to set-off any amounts owed to it by
the former owners of the acquired business against any amount the Company owes
under the Trinity Notes. The Company expects to issue subordinated notes
similar to the Trinity Notes, along with other forms of consideration, in
connection with future acquisitions.

NEW ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("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 will begin publishing the required segment
information in its 1998 annual report on Form 10-K.
 
  In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") 98-1, "Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use," which
establishes new accounting and reporting standards for the costs of computer
software developed or obtained for internal use. This statement will be
applied prospectively and is effective for fiscal years beginning after
December 15, 1998. The Company believes that implementation of this new
standard will not have a significant effect on the Company's financial
position or results of operations.
 
  In April 1998, the AICPA issued SOP 98-5, "Reporting on the Costs of Start-
Up Activities," which requires costs of start-up activities to be expensed as
incurred. This statement is effective for fiscal years beginning after
December 15, 1998. The statement requires capitalized costs related to start-
up activities to be expensed as a cumulative effect of a change in accounting
principle when the statement is adopted. The Company believes that the
adoption of this new standard will not have a significant effect on the
Company's financial position or results of operations.
 
  In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes new accounting
and reporting standards requiring that all derivative instruments (including
certain derivative instruments embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at its fair value. The
statement requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met.
Special accounting for qualifying hedges allows a derivative's gains and
losses to offset related results on the hedged item in the income statement
and requires that a company must formally document, designate, and assess the
effectiveness of transactions that receive hedge accounting. This statement is
effective for all fiscal years beginning after June 15, 1999. The Company has
not yet determined the impact this standard will have on its financial
position or results of operations.

                        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 $230 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 a copy of which is available from the Company.
 
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 October 13, 2001.
 
SECURITY; GUARANTEES
 
  Borrowings under the Credit Agreement are guaranteed by the Company's
domestic Subsidiaries (as defined in the Credit Agreement), including future
domestic 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 domestic
Subsidiaries, and by a pledge of stock of its domestic Subsidiaries.
 
INTEREST RATES
 
  Loans under the Credit Agreement bear interest at a rate per annum, at the
Company's option, of either (i) the Alternate Base Rate which is equal to the
greater of the Federal Funds Effective Rate (as defined in the Credit
Agreement) plus 0.5% or the Prime Rate (as defined in the Credit Agreement)
plus a margin depending on the ratio of indebtedness for borrowed money to
Adjusted EBITDA (as defined in the Credit Agreement), or (ii) the Eurodollar
Rate (as defined in the Credit Agreement) plus a margin depending on the ratio
of indebtedness for borrowed money to Adjusted EBITDA.
 
FEES, EXPENSES AND COSTS; CREDIT FACILITIES
 
  The terms of the Credit Agreement require the Company to pay the following
fees in connection with the maintenance of loans under the Credit Agreement:
(i) commitment fees to be paid to the Lenders in amounts between 0.25% and
0.375% per annum with respect to the unused commitments under the Credit
Agreement depending on the ratio of indebtedness for borrowed money to
Adjusted EBITDA, payable quarterly in arrears until such time as such facility
is terminated; and (ii) administration fees payable annually to the Agent. In
addition, the Company paid various underwriting and arrangement fees and
closing costs in connection with the origination and syndication of the Credit
Agreement.
 
  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.
 
                                      23

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

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

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

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

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

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

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

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

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

  Inventories 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.

 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and

statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Cash and Cash Equivalents
 
  For purposes of the statement of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest and taxes were $99,838 and
$114,955, respectively, for the year ended March 31, 1997.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis, using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Inventories
 
  Inventories consist primarily of purchased materials and supplies. The
inventory is valued at the lower of cost or market, with cost determined on a
first-in, first-out (FIFO) basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease-term or the
estimated life of the asset.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property or equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain
or loss is recognized in the statement of operations.

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

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

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

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

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

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

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

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

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

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

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

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

                   CENTRAL CAROLINA AIR CONDITIONING COMPANY
 
                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION
 
  Central Carolina Air Conditioning Company (the Company) is primarily engaged
in the installation and servicing of heating and air conditioning systems for
residential and commercial customers in the Greensboro and Winston Salem,
North Carolina areas.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the eight months ended June 30, 1996
and as of September 30, 1997 and for the eleven months ended September 30,
1996 and 1997, are unaudited, and certain information and footnote
disclosures, normally included in financial statements prepared in accordance
with generally accepted accounting principles, have been omitted. In the
opinion of management, all adjustments, consisting only of normal recurring
adjustments, necessary to fairly present the financial position, results of
operations and cash flows with respect to the interim financial statements,
have been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid debt instruments with a maturity of three months or less to be
cash equivalents. Cash payments for interest were $9,841 and $3,087 for the
year ended October 31, 1996 and the eight months ended June 30, 1997,
respectively.
 
 Inventories
 
  Inventories consist of parts and supplies used mainly in the service portion
of the Company's operation. The inventory is valued at the lower of cost or
market, with cost determined on a first-in, first-out (FIFO) basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated life of the asset.
 
 
                                      99
<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.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION
 
  Hallmark Air Conditioning, Inc. and subsidiary (the Company) is primarily
engaged in the installation and servicing of heating and air conditioning
systems for residential and light commercial customers in Houston and San
Antonio, Texas.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The consolidated financial statements include the financial statements of
Hallmark Air Conditioning, Inc. (Hallmark) and its wholly-owned subsidiary,
Jerry Albert Air Conditioning, Inc. (Jerry Albert). All significant
intercompany balances and transactions have been eliminated in consolidation.
 
 Interim Financial Information
 
  The interim consolidated financial statements for the three months ended May
31, 1996 are unaudited, and certain information and footnote disclosures,
normally included in financial statements prepared in accordance with
generally accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the consolidated interim financial statements, have
been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the
consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Revenue Recognition
 
  Revenue is recognized upon completion of service. Revenues on service and
maintenance contracts are recognized over the life of the contract.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest and taxes were $32,261 and
$54,300, respectively, for the year ended February 28, 1997, and $28,310 and
$-0-, respectively, for the three months ended May 31, 1997.
 
 Inventories
 
  Inventories consist primarily of purchased materials and supplies. The
Company uses the first-in, first-out (FIFO) cost method to value its
inventories.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the estimated useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated useful life of the asset.
 
 
                                      109
<PAGE>
 
                HALLMARK AIR CONDITIONING, INC. AND SUBSIDIARY
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

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

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

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

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

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

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

                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION
 
  Sibley Services, Incorporated (the Company) is primarily engaged in the
installation and servicing of heating and air conditioning systems for
commercial and industrial customers in Memphis, Tennessee and the surrounding
area.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Interim Financial Information
 
  The interim financial statements for the eight months ended June 30, 1996
are unaudited, and certain information and footnote disclosures, normally
included in financial statements prepared in accordance with generally
accepted accounting principles, have been omitted. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the interim financial statements, have been
included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Revenues from work orders are recognized as services are performed. Revenues
on service and maintenance contracts are recognized over the life of the
contract. Revenues from construction contracts are recognized on a percentage
of completion basis using the cost-to-cost method. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses
are determined. Changes in job performance, job conditions, and estimated
profitability may result in revisions to costs and revenues and are recognized
in the period in which the revisions are determined.
 
 Cash and Cash Equivalents
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to
be cash equivalents. Cash payments for interest and taxes were $26,004 and
$130,791, respectively, for the year ended October 31, 1996. Cash payments for
interest and taxes were $10,589 and $9,500, respectively, for the eight months
ended June 30, 1997.
 
 Inventories
 
  Inventories consist primarily of purchased materials. The inventory is
valued at the lower of cost or market, with cost determined on a first-in,
first-out (FIFO) basis.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the useful lives of the assets. Leasehold
improvements are amortized over the lesser of the remaining lease term or the
estimated life of the asset.
 
                                      120

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

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

                      SOUTHEAST MECHANICAL SERVICE, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

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

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

            WILLIS REFRIGERATION, AIR CONDITIONING & HEATING, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

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

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

                         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.

                               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.

 INCOME TAXES
 
  The shareholder of the Company has elected to be taxed for federal and
Virginia tax purposes as an S Corporation whereby the taxable income of the

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

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

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

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

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

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

responsibility is to express an opinion on these 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 out audit provides 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 HPS Plumbing Services,
Inc. as of March 31, 1998, and the results of its operations and its cash
flows for the nine months then ended in conformity with generally accepted
accounting principles.

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

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

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

                                                                           -----
      <S>                                                                  <C>

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

6. LEASES
 
  The Company leases its building space and office equipment from its
president. The Company moved into this building in November 1997. The building
rental agreement provides that the Company pay all property taxes, insurance
and maintenance. The building agreement has an annual rental of $120,000 and
the equipment agreement has an annual rental of $25,800. Rent expense for the
lease of office and warehouse space during the nine months ended March 31,
1998 was $58,520. The primary term of the building lease is 5 years with 5
options to extend of one year each. The equipment lease agreement is on a
monthly basis.
 
  The building lease agreement provides that an adjacent tenant may move into
the Company's space during a period beginning on October 1, 2001 and ending on
October 1, 2003. If this option is exercised, the Company would be forced to
move and would be reimbursed for its costs by the lessor in the amount of
$350,928. This amount decreases by $14,622 per month, beginning November 1,
2001.
 
  In addition, the Company leases various trucks, trailers and office

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

The Board of Directors
Ray & Claude Goodwin,Inc.
 
  We have audited the accompanying balance sheet of Ray & Claude Goodwin,Inc.
as of December 31, 1997, and the related statements of operations,
stockholders' equity and cash flows for the year then ended. 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 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 out audit provides 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 Ray & Claude Goodwin,Inc.
as of December 31, 1997, and the results of its operations and its cash flows
for the year then ended in conformity with generally accepted accounting
principles.

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

      <S>                                                            <C>

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

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

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

3. EMPLOYEE BENEFIT PLANS
 
  The Company has a qualified noncontributory defined contribution plan
covering employees who have had one year of continuous service and meet
certain other eligibility requirements set forth in the plan. Contributions to
the plan are at the discretion of management. There were no contributions to
the plan for the year ended December 31, 1997.
 
4. LEASES
 
  The Company leases its building space on a verbal, month-to-month lease from
the shareholders at $4,700 per month. Management intends and has the ability
to continue to renew its lease with related parties. The Company pays all
property taxes, insurance and maintenance. Rent expense for the lease of
building space during the year ended December 31, 1997 was $42,000.
 
5. COSTS AND ESTIMATED EARNINGS ON UNCOMPLETED CONTRACTS
 
  A summary of the status of uncompleted contracts as of December 31, 1997 is

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

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

      <S>                                                             <C>

                                                                      $6,786,939
                                                                      ==========
</TABLE>
 
  The Company considers accounts receivable to be fully collectible;
accordingly, no allowance for doubtful accounts is required.
 
 Notes Receivable
 
  The notes receivable, including amounts due from related parties, consist of
loans to certain employees and stockholders. Management considers the balances
due from stockholders as current due to the ability of the stockholders to
repay the loans on demand. Interest is accrued on an annual basis at 7%. Non-
stockholder notes receivable are payable in monthly installments and accrue
interest at rates ranging from 7% to 9%.
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight line method over the useful lives of the assets. Expenditures for
major renewals and improvements, which extend the useful lives of existing
equipment, are capitalized and depreciated. The estimated useful lives of
assets are 5 years for all classes of assets.
 
  Expenditures for repairs and maintenance are charged to expense when
incurred. Upon retirement or disposition of property and equipment, the cost
and related accumulated depreciation are removed from the accounts and any
resulting gain or loss is recognized in the statements of operations.
 
 Short-term Investments and Marketable Securities
 
  Short-term investments are carried at cost, which approximates fair value.
The Company accounts for marketable securities in accordance with SFAS No.
115, Accounting for Certain Investments in Debt and Equity Securities. All of
the Company's marketable securities (all of which are equity securities and
investments in mutual funds) have been classified as available for sale with
unrealized gains or losses recorded as a separate component of shareholders'
equity. As of December 31, 1997 the cost of the marketable securities was
$422,821 and unrealized gains were $212,907, with no unrealized losses.
 
 Income Taxes
 
  The shareholders of the Company elected to be taxed for federal tax purposes
as an S Corporation whereby the shareholders' respective equitable shares in
the taxable income of the Company are reportable on their individual tax
returns. The Company has made distributions to the shareholders each year at
least in amounts necessary to pay personal income taxes payable on the
Company's taxable income.
 
  Due to its operations in Puerto Rico, the Company is required to pay
corporate income taxes in Puerto Rico. These amounts are recorded as income
tax expense. The total tax expense for the year ended December 31, 1997 was
$48,060. As of December 31, 1997, deferred income taxes are insignificant.
 
 New Accounting Pronouncement
 
  In June 1997, SFAS No. 130, Reporting Comprehensive Income was issued. This
statement establishes standards for reporting and displaying comprehensive
income and its components in a financial statement that is
 
                                      209

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

                                                                      =========

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