                          INDEPENDENT AUDITOR'S REPORT

To the Board of Trustees of
ACS Defense, Inc.
Profit Sharing and 401(K) Plan
5 Burlington Woods Drive
Burlington, MA 01803

We were engaged to audit the financial statements of ACS Defense, Inc. Profit
Sharing and 401(K) Plan as of December 31, 1999 and 1998, and for the years then
ended, and the supplemental schedules as of and for the year ended December 31,
1999 as listed in the accompanying index. These financial statements and
schedules are the responsibility of the Plan's management.

As permitted by 29 CFR 2520.103-8 of the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974, the plan administrator instructed us not to perform, and
we did not perform, any auditing procedures with respect to the information
summarized in Note 3, which was certified by CG Trust Company, the trustee of
the Plan, except for comparing the information with the related information
included in the financial statements and supplemental schedules. We have been
informed by the plan administrator that the trustee holds the Plan's investment
assets and executes investment transactions. The plan administrator has obtained
a certification from the trustee as of and for the years ended December 31, 1999
and 1998, that the information provided to the plan administrator by the trustee
is complete and accurate.

Because of the significance of the information that we did not audit, we are
unable to, and do not, express an opinion on the accompanying financial
statements and schedules taken as a whole. The form and content of the
information included in the financial statements and schedules, other than that
derived from the information certified by the trustee, have been audited by us
in accordance with generally accepted auditing standards and, in our opinion,
are presented in compliance with the Department of Labor's Rules and Regulations
for Reporting and Disclosure under the Employee Retirement Income Security Act
of 1974.

                         PROFIT SHARING AND 401(K) PLAN
                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1999 AND 1998

NOTE 1 - DESCRIPTION OF THE PLAN

        The following description of the ACS Defense, Inc. Profit Sharing and
        401(K) Plan provides only general information. Participants should refer
        to the Plan agreement for a more complete description of the Plan's
        provisions. Effective April 1, 1998 the Analytical Systems Engineering
        Corporation Profit Sharing and Analytical Systems Engineering
        Corporation 401(K) Plan were merged and became the ACS Defense, Inc.
        Profit Sharing and 401(K) Plan.

        As of April 1, 1998 the trustee of the Plan was changed from Vanguard
        Fiduciary Company Trust to CG Trust Company.

        GENERAL - The Plan is a 401(K) and a profit sharing plan. The Plan is
        designed to allow full-time employees to contribute a portion of their
        salary and allows the employer to "match" a percentage of their
        contribution. It also allows the employer to make an additional "profit
        sharing" contribution to the plan. It is subject to the provisions of
        the Employee Retirement Income Security Act of 1974 (ERISA).

        CONTRIBUTIONS - The Plan is funded with voluntary employee deferrals and
        employer contributions.

        PARTICIPANT ACCOUNTS - Each participant's account is credited with the
        participant's contribution and allocations of (a) the Company's profit
        sharing and matching contribution and, (b) plan earnings and, (c)
        forfeitures of terminated participants' nonvested accounts, and charged
        with an allocation of administrative expenses. Allocations are based on
        participant earnings or account balances, as defined. The benefit to
        which a participant is entitled is the benefit that can be provided from
        the participant's vested account.

        VESTING - Participants are immediately vested in their contributions
        plus actual earnings thereon. Vesting in the company's contribution
        portion of their accounts plus actual earnings thereon is based on years
        of continuous service. A participant is 100% vested after seven years of
        credited service.

        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 due to other reasons, a participant may receive
        the value of the vested interest in his or her account as a lump-sum
        distribution.

        PARTICIPANT LOANS - Participants may borrow from their fund accounts a
        minimum of $1,000 up to a maximum of $50,000 or 50% of their account
        balance, whichever is less. The loans are secured by the balance in the
        participant's account and bear interest at rates ranging from 6% to 10%,
        which are commensurate with local prevailing rates as determined
        quarterly by the Plan administrator. Principal and interest is paid
        ratably through monthly payroll deductions.

        The preparation of financial statements in conformity with generally

        the Plans' trustee and manages the plan assets.
