REPORT OF INDEPENDENT ACCOUNTANTS ------------------------- To the Board of Trustees and Plan Administrators of Bolt Beranek and Newman Inc. Retirement Trust: We have audited the statements of net assets available for plan benefits of the Bolt Beranek and Newman Inc. Retirement Trust (the "Plan") as of June 30, 1993 and 1992 and the related statement of changes in net assets available for plan benefits for the year ended June 30, 1993. These financial statements are the responsibility of the Plan Administrators and the Board of Trustees. 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 net assets available for plan benefits of the Plan as of June 30, 1993 and 1992, and the changes in net assets available for plan benefits for the year ended June 30, 1993 in conformity with generally accepted accounting principles. Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are 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. The supplemental schedules have been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, are fairly stated in all material respects, in relation to the basic financial statements taken as a whole.

BOLT BERANEK AND NEWMAN INC. RETIREMENT TRUST NOTES TO FINANCIAL STATEMENTS ------------------------- A. Trust Description: ------------------ The Bolt Beranek and Newman Inc. Retirement Trust (the "Plan") is a qualified defined contribution plan established in 1954 to provide retirement benefits for domestic employees of Bolt Beranek and Newman Inc. and its subsidiaries (hereinafter Bolt Beranek and Newman Inc. and its participating subsidiaries are referred to as the "Company") who have completed one year of service, as defined. Participants should refer to the plan agreement for a more complete description of the Plan's provisions. B. Summary of Significant Accounting Policies: ------------------------------------------- Investments Valuation --------------------- Investments in mutual and money market fund shares are valued based on reported net asset values. Investments in common stocks are carried at quoted market values. The investment in the John Hancock Venture Capital Fund, a limited partnership, is carried at the Plan's proportionate share of the Fund's net asset value. The Plan's limited partnership interest is not readily marketable. The Plan presents in the statement of changes in net assets available for Plan benefits the net appreciation in the fair value of its investments which consists of net realized gains of $1,015,414 and the unrealized appreciation of $13,871,675 on those investments. Contributions ------------- The Plan receives contributions as voted annually by the Company according to the terms of the Plan. Employer contributions are recorded for each plan year in such amounts as have been voted by the Company pursuant to the provisions of the Plan and include amounts paid directly to participants as elective cash options, if any. Employee contributions are recorded in the period when received from the participant directly or in which the Company makes payroll deductions from those Plan participants who have authorized voluntary contributions to be withheld. Employee contributions are subject to certain limitations imposed by the Internal Revenue Code and may require the subsequent return of a portion of the contributions made during the previous plan year. Other ----- Purchases and sales of securities are reflected on a trade-date basis. Gains or losses on sales of investments are determined based on the average cost method. BOLT BERANEK AND NEWMAN INC. RETIREMENT TRUST NOTES TO FINANCIAL STATEMENTS, Continued ------------------------- B. Summary of Significant Accounting Policies, continued: ------------------------------------------------------ Other, continued ---------------- Investment income includes dividends, capital gains distributions and interest income and are reinvested as earned. Dividends and capital gains distributions are recorded on the ex-dividend date. Interest income is recorded as earned. The management and service fees of the Fidelity Group of Funds are charged to operations of the respective funds. C. Plan Provisions: ---------------- Vesting ------- Plan participants are 100% vested (benefits to which the participant is entitled regardless of future service with the Company) in the portion of the annual employer contribution credited to their account which exceeds 7 1/2% of their credited compensation, as defined. The remaining portion of the participants' account balance vest at the rate of 2 1/12% per month; thus upon completion of four years of participation, employees become fully vested. Upon disability, attainment of age 65 or death, employees become fully vested with respect to all of the employer contributions. Forfeitures ----------- Forfeitures of nonvested employer credits are allocated to the remaining plan participants as provided by the plan. Benefit Payments ---------------- Employees may commence to receive benefits after retirement on or after age 55 or upon total disability. These benefits may be paid in a lump sum or in installments over a period of up to 15 years. Benefits must commence no later than April 1 following the calendar year in which the participant attains age 70 1/2. Upon death the participant's designated beneficiary is entitled to receive the amount in the participant's account. If a participant leaves for reasons other than death, total disability or retirement on or after 65, vested benefits (a) will be paid in lump sum if the total vested balance does not exceed $3,500, (b) may be paid in a lump sum if the total vested balance exceeds $3,500 but is less than $7,500, (c) will be deferred to the earlier of age 55 or three years after termination if the vested balance at termination is at least $7,500. BOLT BERANEK AND NEWMAN INC. RETIREMENT TRUST NOTES TO FINANCIAL STATEMENTS, Continued ------------------------- C. Plan Provisions, continued: --------------------------- Withdrawals ----------- A participating employeee may withdraw their voluntary contributions up to the lesser of the then current value of their contributions or the actual amount contributed by the participating employee, provided that at least $500 is withdrawn. Contributions withdrawn cannot be reinvested. No other amounts are available for in-service withdrawl except for loans. Loans ----- With the approval of the Trust Administrators (the "Administrators"), participants may borrow an amount up to one-half of the vested interest in their accounts, with the maximum amount loaned not to exceed $50,000. Interst is charged at a reasonable fixed rate established by the Administrators which approximate market rates (10% as of January 6, 1993). The loan must be repaid in substantially equal installments, payable no less frequently than quarterly, within a reasonable period specified by the Administrators, not to exceed five years. D. Investment Funds of the Plan: ----------------------------- A description of the investment funds of the Plan at June 30, 1993 is as follows: - Fidelity's U.S. Government Fund replaced the Retirement Government Money Market Portfolio as of March 1, 1993, and is generally intended for investors in tax-saving retirement plans. The Fund seeks as high a level of current income as is consistent with the preservation of capital and liquidity by investing in obligations issued or guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities, and in repurchase agreements secured by these obligations. The Fund's objective is to be a conservative, low-risk investment. - Fidelity Puritan Fund is a growth and income fund. The Fund's investment objective emphasizes income by investing in a broadly diversified portfolio of high-yielding securities. These securities include common stock, preferred stock, and bonds. The Fund seeks to achieve capital growth in addition to regular quarterly dividends. BOLT BERANEK AND NEWMAN INC. RETIREMENT TRUST NOTES TO FINANCIAL STATEMENTS, Continued ------------------------- D. Investment Funds of the Plan, continued: ---------------------------------------- - Fidelity Equity-Income Fund is a growth and income fund. The Fund seeks a yield that exceeds the composite yield of the Standard and Poor's 500 Index, and considers the potential for capital appreciation when selecting fund investments. The Fund invests primarily in common and preferred stocks, but can also invest in bonds and convertible securities. Dividend amounts will vary, depending on the yields of the securities held in the portfolio. - Fidelity Magellan Fund is a growth fund. The Fund seeks long-term capital appreciation by investing in stocks of both well-known and lesser-known companies with above-average growth potential and a correspondingly higher level of risk. Securities may be of foreign and domestic companies. - Fidelity Europe Fund is a growth fund which seeks long-term capital appreciation by investing in securities of issuers that have their principal activities in Western Europe. The Fund invests primarily in foreign securities, including common stock, securities convertible into common stock, and debt instruments. - Fidelity U.S. Equity Index Portfolio (a portfolio of Fidelity Institutional Trust) seeks to provide investment results that correspond to the total return performance of the companies comprising the Standard & Poor's 500 index. - Trustees' Fund investments include the remaining investments of a former investment option and a money market fund account to accumulate interim employer contributions. At June 30, 1993, the investments consist of money market funds and a venture capital fund. - The BBN Stock Fund allows participants to allocate up to 15% of the value of their accounts in this Fund which consists solely of the Company's common stock. BOLT BERANEK AND NEWMAN INC. RETIREMENT TRUST NOTES TO FINANCIAL STATEMENTS, Continued ------------------------- D. Investment Funds of the Plan, continued: ---------------------------------------- Participants may reallocate their individual accounts among the available investment options once each month. No allocations are allowed to or from the Trustees' Fund. Proceeds from investments maturing or sold in this fund will be invested in the Fidelity mutual funds in accordance with the participants selected fund allocations. E.

Additionally, at June 30,1993, $75,033,180 of the Plan's investment assets belong to persons who do not have active accounts in the Plan, and who have not yet received disbursement of their account balance. BOLT BERANEK AND NEWMAN INC. RETIREMENT TRUST NOTES TO FINANCIAL STATEMENTS, Continued ------------------------- F. Tax Status: ----------- The Internal Revenue Service has determined that the Plan is a qualified plan under Section 401(a) of the Internal Revenue Code and is therefore exempt from federal income taxes under the provisions of Section 501(a). The most recent amendment, made in connection with the most recent IRS determination letter, was made to the Plan during fiscal 1993. G. Administrative Expenses: ------------------------ Administrative expenses consist primarily of those costs associated with the independent audit and charges assessed by the Plan's recordkeeper. Certain other administrative expenses of the Plan are absorbed directly by the Company. H. Termination Priorities: ----------------------- While the Company has established the Plan with the intention and expectation that contributions will continue indefinitely, the Company may terminate the Plan at any time without any liability whatsoever for such discontinuance or termination. In the event that the Board of Directors of the Company votes to terminate the Plan, the Plan would be discontinued as of the date specified in the notice of termination directed to the Board of Trustees (the "Trustees"). Upon such termination of the Plan, each participating employee's interest in employer credits would become fully vested and nonforfeitable. After payment of proper expenses by the Trustees, the Trust would be liquidated and each participating employee (or beneficiary of a deceased participating employee) would be entitled to receive their interest in the Trust fund, as of the date of liquidation, in cash or in kind, a single payment. Net assets available for plan benefits at June 30, 1993 do not reflect any provision for liquidation expenses or for costs related to disposition of investments. Participants remaining at the time of liquidation would bear all such investment costs. I.
