F-5 <Page> 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 F-6 <Page> 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: <Table> <Caption> YEAR ENDING DECEMBER 31, - ------------------------ 1999 (July 15-Dec. 31)...................................... $ 126,500 2000........................................................ 276,000 2001........................................................ 276,000 2002........................................................ 276,000 2003........................................................ 299,000 Thereafter.................................................. 4,781,500 ---------- $6,035,000 ========== </Table> Total rent expense for the year ended December 31, 1998 and for the period from January 1, 1999 to July 14, 1999 was approximately $224,000 and $161,000, respectively. LEGAL MATTERS The Company is subject to various legal matters, which it considers normal for its business activities. Management believes, after consultation with legal counsel, that these matters will not have a material impact on the financial condition, liquidity or results of operations of the Company. ENVIRONMENTAL MATTERS The process to manufacture circuit boards requires adherence to city, county, state and federal environmental regulations regarding the storage, use handling and disposal of chemicals, solid wastes and other hazardous materials as well as air quality standards. Management believes that its facilities comply in all material respects with environmental laws and regulations. The Company has in the past F-7 <Page> POWER CIRCUITS, INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) received certain notices of violations and has been required to engage in certain minor corrective activities. There can be no assurance that violations will not occur in the future. 4. EMPLOYEE BENEFIT PLAN The Company maintains a 401(k) savings plan (the "Plan") under which all full-time employees 18 years of age or older with at least one year or 1,000 hours of service are eligible to participate. Under the Plan, eligible employees voluntarily contribute to the Plan up to 15% of their salary through payroll deductions. Employer contributions may be made by the Company at its discretion based upon matching employee contributions, within limits, and profit sharing provided for in the Plan. Employer contributions of $42,400 and $20,625 were made for 1998 and for the period from January 1, 1999 to July 14, 1999, respectively. 5. BONUSES In July 1999, just prior to the sale of the Company, the Company paid one-time bonuses to its employees totaling $3,395,000. F-8
