                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
and Stockholders of
Avtech Corporation
 
    In our opinion, the accompanying balance sheets and the related statements
of income, of stockholders' equity and of cash flows present fairly, in all
material respects, the financial position of Avtech Corporation at September 30,
1996 and 1997 and March 31, 1998, and the results of its operations and its cash
flows for each of the three years in the period ended September 30, 1997 and the
six months ended March 31, 1998, in conformity with generally accepted
accounting principles. 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 of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
DESCRIPTION OF THE COMPANY
 
    Avtech Corporation (the Company) is a custom design and manufacturing firm
established in 1963 to produce high-quality equipment for the aircraft industry.
In 1970, Avtech began to produce engineered products and has since focused its
engineering and product development efforts on responding to specifications from
original equipment aircraft manufacturers (OEMs). The Company's products fall
into five main categories:
 
1.  Aircraft communication control equipment (including audio control units,
    multiplexed audio systems and audio amplifiers).
 
2.  Aircraft lighting controls (including ballasts, dimmers and flood lighting).
 
3.  Power systems (including transformer rectifier units, power inverters and
    battery chargers).
 
4.  Airborne facsimile terminals (AvFax).
 
5.  Special products (including PDX intercoms, liquid-gauging and fill control,
    and frequency units).
 
FINANCIAL STATEMENT PRESENTATION
 
    The presentation 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 the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
    At September 30, 1996 and 1997 and March 31, 1998, the Company maintained
$549,000, $119,000 and $868,000 respectively, of its cash and cash equivalents
balances at one bank. At September 30, 1996 and 1997 and March 31, 1998, the
Company maintained $503,000, $4,017,000 and $2,392,000, respectively, in a money
market fund and bankers' acceptances.
 
RECEIVABLES AND CONCENTRATIONS OF CREDIT RISK
 
    Accounts receivable from trade customers are generally due within thirty
days. The Company performs periodic credit evaluations of its customers'
financial conditions and generally does not require collateral. All of the
Company's sales are to businesses directly associated with the aviation industry
(airlines, aircraft manufacturers, etc.). Approximately 70% of the Company's
sales are to customers based in the United States.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
PROPERTY AND EQUIPMENT
 
    The cost of property, plant and equipment is depreciated over the estimated
useful lives of the related assets. Depreciation is computed using the
straight-line and accelerated methods over the following estimated lives:
 


                                                                                          YEARS
                                                                                        ---------
                                                                                     
Buildings.............................................................................    20-39
Building improvements.................................................................    10-39
Machinery and equipment...............................................................      5
Furniture, computer and other equipment...............................................     5-7

 
    Maintenance and repairs are charged to operations when incurred. Additions
and improvements are capitalized. When property, plant and equipment are sold or
otherwise disposed of, the asset account and related accumulated depreciation
account are relieved, and any gain or loss is included in operations.
 
INVENTORIES
 
    Inventories are stated at the lower of cost (determined by the first-in,
first-out method) or market. Costs of manufactured inventories include all
direct materials, labor and an allocation of overhead. Market represents the
lower of replacement cost or estimated net realizable value.
 
REVENUE RECOGNITION
 
    Revenues from the sale of manufactured products are recorded when shipped.
Reimbursements for nonrecurring engineering costs, which are expensed as
incurred, are included in revenues at the time a negotiated settlement is
reached with the customer. The Company's nonrecurring engineering revenues for
the years ended September 30, 1995, 1996 and 1997 and the six months ended March
31, 1998 were $1,257,000, $4,042,000, $527,000 and $138,000, respectively.
Included within accounts receivable at September 30, 1996 are $3,384,000 of
unbilled receivables which were collected in fiscal year 1997.
 
INCOME TAXES
 
    Deferred income taxes are determined using the liability method. A deferred
tax asset or liability is determined based on the difference between the
financial statement and tax basis of assets and liabilities as measured by the
enacted tax rates which will be in effect when these differences reverse.
Deferred tax expense is the result of changes in the asset and/or liability for
deferred taxes.
 
STOCK OPTION PLAN
 
    As permitted under Statement of Financial Accounting Standards No., 123,
"Accounting for Stock-Based Compensation" (SFAS 123), the Company measures
compensation expense related to the employee stock option plan utilizing the
intrinsic value method as prescribed by Accounting Principles Board No. 25,
"Accounting for Stock Issued to Employees".

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
ACCRUED WARRANTIES
 
    The Company sells a majority of its products to customers along with various
repair or replacement warranties. The terms of the warranties vary according to
the customer and/or the product involved. The most common warranty period is the
earlier of:
 
a.  36 months from the date of delivery to the operator, or;
 
b.  42 months from the date of manufacture
 
    Provisions for estimated future warranty costs are made in the period
corresponding to the sale of the product. Classification between short and
long-term warranty obligations is estimated based on historical trends.
 
UNAUDITED INTERIM RESULTS
 
    The financial information for the six months ended March 31, 1997 is
unaudited. In the opinion of the Company, the unaudited financial information is
presented on a basis consistent with the audited financial statements and
contains all adjustments, consisting only of normal recurring adjustments,
necessary for a fair statement of the results for such interim period. The
results of operations for the interim periods are not necessarily indicative of
results of operations for the full year.

    Inventories at September 30, 1996 and 1997 and March 31, 1998 consist of the

NOTE 3 - PROPERTY AND EQUIPMENT
 
    The Company owns property located immediately adjacent to its main facility.
The property is not currently used for any rental or productive activity. In
1990, the property was condemned by the local authorities and is considered
unsuitable for habitation in its current state. The current carrying value of
$62,000 represents the original cost of the land and is lower than its estimated
net realizable value.
 
    In 1997, the Company purchased a 20,275 square foot office building and an
adjacent vacant lot for investment purposes. The net book value of the property
was $2,134,000 and $2,098,000 at September 30, 1997 and March 31, 1998,
respectively. The Company leases the office space to tenants under one to three-

NOTE 8 - ECONOMIC DEPENDENCE
 
    A material part of the Company's business is dependent on one customer, the
loss of which could have a material effect on the Company. For the years ended
September 30, 1995, 1996 and 1997 and the six months ended March 31, 1998,
approximately 29.5%, 24%, 46.9% and 41.7%, respectively, of revenues were
attributable to this customer. At September 30, 1996 and 1997 and March 31,
1998, accounts receivable from this customer represented approximately 41.1%,
23.4% and 30%, respectively, of total accounts receivable.
 
NOTE 9 - STOCK OPTION PLANS
 
    Prior to 1993, the Company implemented a nonqualified compensatory stock
option plan with the President. Under this Plan, options to purchase 90,000
shares of the Company's stock were granted at an option price of $2.70 per
share. These options are currently exercisable by the President.
 
    During the year ended September 30, 1994, the Company and three key
employees entered into employment contracts which voided all prior compensatory
stock option plans other than that of the President's. Under these new
contracts, the Company granted 20,000 shares to each of the three employees at
an exercise price of $15 per share. Fair market value was $28 per share at the
date of the grant. Each

employee still employed at September 30, 1998, is entitled to exercise his
option to purchase 20,000 fully vested shares. Accordingly, the Company has
expensed $156,000 during each of the years ended September 30, 1995, 1996 and
1997 and $78,000 for the six months ended March 31, 1998. These shares, when
exercised, cannot be sold until September 30, 2003. The Company has the first
right to purchase the shares upon exercise but is not obligated to do so.
 
    The accumulated expense resulting from the difference between the exercise
prices and fair market values at the respective date of grant has been
classified as a long-term liability in deferred compensation.
