These financial statements are the responsibility of the Plan'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 auditing standards generally accepted in the United States of America, 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 our opinion. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule of Assets (Held at End of Year) as of December 31, 2001, is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ PricewaterhouseCoopers LLP PricewaterhouseCoopers LLP Pittsburgh, PA April 30, 2002 - 2 - SENSYTECH, INC.

DESCRIPTION OF PLAN AND BENEFITS The following description of the Sensytech, Inc. 401(k) Profit-Sharing Plan (the "Plan") provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. GENERAL The Plan is a defined contribution, stock bonus and profit-sharing plan covering all full-time employees of Sensytech, Inc. (the "Company") who meet the eligibility requirements of the Plan. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). CONTRIBUTIONS Each year, participants may make contributions up to 15% of pretax annual compensation into the Plan, subject to statutory limitations. Participants direct the investment of their contributions into various investment options offered by the Plan. The Plan currently offers thirteen mutual funds and the Company's common stock as investment options for participants. The Company contributes to the Plan at a rate of 50% of the employees' contribution, up to 6% of the employees' salary. Company contributions are allocated among investment options at the direction of participants. Additional contributions may be made by the Company at its discretion. In no event shall Company contributions for any year exceed the maximum amount deductible under the provisions of the Internal Revenue Code. PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contribution, (b) Plan earnings, and (c) forfeiture of terminated participants' nonvested accounts. Allocations are based on participant account balances or compensation, as defined, as appropriate. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. VESTING Participants are vested immediately in their contributions plus actual earnings thereon. Vesting in the Company's contribution portion of their accounts is based on years of continuous service. A participant vests 20% per year of continuous service after three years and becomes 100% vested after seven years of credited service. PARTICIPANT LOANS Participants may borrow from their individual account balances. The Plan allows a loan amount from a minimum of $1,000 up to a maximum of $50,000 or 50% of their vested account balance, whichever is less. The term of the loan may not exceed five years unless used to acquire a principal residence. The loans are collateralized by the remaining vested balance in the participant's account and bear interest at rates equal to the Federal Reserve Prime Rate on the date of the loan plus 1%. PAYMENT OF BENEFITS On termination of service due to death, disability or retirement, a participant may elect to receive either a lump-sum amount equal to the value of the participant's vested interest in his or her account, or annual installments over a ten-year period. For termination of service for other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution. Benefits are recorded by the Plan when paid. -5- SENSYTECH, INC. 401(k) PROFIT-SHARING PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2001 AND 2000 - ------------------------------------------------------------------------------- FORFEITURES Company contributions that are not vested upon termination of employment are forfeited and will be used to reduce future Company contributions. In 2001, forfeitures totaling $23,621 were used to off-set current year employer matches. As of December 31, 2001, forfeitures totaling $48,380 are unallocated and available to offset further employer contributions. PLAN TERMINATION Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The financial statements of the Plan have been prepared on the accrual basis of accounting and in conformity with accounting principles generally accepted in the United States of America. RISKS AND UNCERTAINTIES The Plan provides for various investment options. These investments are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in the near term could materially affect participant account balances and the amounts reported in the statement of net assets available for benefits and the statement of changes in net assets available for benefits. ADMINISTRATIVE EXPENSES All mutual funds incur expenses that reduce earnings in the fund and are reflected in the daily Net Asset Value (NAV). The amount of these expenses, stated as a percentage of assets, is called an expense ratio. The NAVs for the mutual funds are listed publicly and the same NAV applies whether the mutual fund is purchased on the open market or through the Plan. Expense ratios charged by mutual funds cover costs relating to investing, such as the mutual fund managers' asset management fees and costs related to administration of the fund. Examples of administrative costs include issuing quarterly statements, operating a service center and having toll-free phone numbers available for the participants. Expenses incurred by the mutual funds are netted against earnings of the respective funds in the accompanying statement of changes in net assets available for benefits. Other administrative expenses, including trustee, legal, auditing, and other fees, are paid by the Company and, as such, are not expenses of the Plan. INVESTMENT VALUATION AND INCOME RECOGNITION The record keeping and trustee functions of the Plan were performed by Legg Mason Wood Walker, Inc. and Emjay Corporation, respectively, through March 31, 2001. Effective April 1, 2001, the record keeping and trustee functions were transferred to Merrill Lynch Trust Corporation FSB, where they are accumulated and invested on behalf of the Plan at the discretion of the participant. Participant account balances were unchanged but were mapped from previous investment options to current investment options. -6- SENSYTECH, INC. 401(k) PROFIT-SHARING PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2001 AND 2000 - ------------------------------------------------------------------------------- The Plan's investments are stated at fair value. Shares of mutual funds and common stock are valued at quoted closing market prices which, for mutual funds, represent the NAV of shares held by the Plan at year-end. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Participant loans are valued at cost, which approximates fair value. USE OF ESTIMATES The preparation of the Plan's financial statements in conformity with accounting principles generally accepted in the United States of America may require the plan administrator to make estimates and assumptions that could affect the reported amounts of assets available for benefits at the date of the financial statements and the changes in assets available for benefits during the reporting period, and, when applicable, disclosure of contingent assets and liabilities. Actual results could differ from those estimates. 3.
