To Power Circuits, Inc.:

    We have audited the accompanying statements of income, shareholders' equity

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

accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements

estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the results of operations and cash flows of Power

                              POWER CIRCUITS, INC.

                         NOTES TO FINANCIAL STATEMENTS

1.  NATURE OF OPERATIONS

    Power Circuits, Inc. ("the Company") was incorporated under the laws of the
State of California. The Company is a manufacturer of complex printed circuit
boards ("PCBs") used in sophisticated electronic equipment. The Company sells to
a variety of original equipment manufacturers located both within and outside of
the United States.

    On July 14, 1999, the Company was acquired by an unrelated entity. These
financial statements represent the operations of the Company prior to the
completion of the transaction.

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 amount of revenues and expenses during the reporting
period. Actual results could materially differ from those estimates in the near
term.

REVENUE RECOGNITION

    The Company derives its revenue primarily from the sale of PCBs using
customer supplied engineering and design plans and recognizes revenues when
products are shipped to the customer.

INVENTORIES

    Inventories are stated at the lower of cost (determined on a first-in,
first-out basis) or market.

PROPERTY, PLANT AND EQUIPMENT

    Property, plant and equipment are depreciated using the straight-line method
over the estimated useful lives of the assets. The Company uses the following
estimated useful lives:

<Table>
                                                           
Buildings...................................................  40 years
Building improvements.......................................  34-40 years
Machinery and equipment.....................................  7-10 years
</Table>

    Major renewals and betterments are capitalized and depreciated over their
estimated useful lives while minor expenditures for maintenance and repairs are
charged to expense as incurred.

INCOME TAXES

    The Company has elected for federal and state income tax purposes to include
its taxable income with that of its shareholders (an S Corporation election).
The provision for income taxes represents the 1.5% state franchise tax which is
based on the Company's California taxable income. The difference between the
expected income tax rate and the Company's effective tax rate is primarily
attributable to the utilization of enterprise zone and manufacturing investment
tax credits. The Company makes distributions to its shareholders for the payment
of income taxes.

    The unaudited pro forma information presents the pro forma effects on
historical net income adjusted for a pro forma provision for income taxes. The
pro forma provision for income taxes has

                              POWER CIRCUITS, INC.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

been determined assuming the Company had been taxed as a C corporation for
federal and state income tax purposes using an effective tax rate of 37%.

CONCENTRATION OF CREDIT RISK

    In the normal course of business, the Company extends credit to its
customers, which are concentrated in the computer, telecommunications, and
electronics instrumentation industries. The Company performs ongoing credit
evaluations of customers and generally does not require collateral. The
Company regularly reviews its accounts receivable and makes provisions for
potential losses.

    Total sales to one customer approximated 24% of net sales in 1998. For
the period from January 1, 1999 to July 14, 1999, this customer accounted for
9% of net sales. This customer represented approximately 17% and 13% of trade
accounts receivable at December 31, 1998 and July 14, 1999, respectively.

3.  COMMITMENTS AND CONTINGENCIES

OPERATING LEASES

    In March 1998, the Company entered into a noncancellable long-term operating
lease for an industrial facility owned by Harbor Building, LLC, an affiliated
entity which expires in 2018.

    As of July 14, 1999, the future minimum lease payments under noncancellable
operating leases are as follows:
