                          INDEPENDENT AUDITORS' REPORT

To the Participants and Plan Committee of
The 401(k) Savings Plan for ACS GSG

We have audited the accompanying statements of net assets available for benefits
of The 401(k) Savings Plan for ACS GSG ("Plan") as of December 31, 1999 and
1998, and the related statement of changes in net assets available for benefits
for the year ended December 31, 1999. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on the financial statements based on our audit. The financial statements
of The 401(k) Savings Plan for ACS-GSG as of December 31, 1998 were audited by
other auditors whose report dated July 30, 1999, expressed a qualified opinion
as permitted by section 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.

Except as discussed in the following paragraph, we conducted our audit 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
audit provides a reasonable basis for our opinion.

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 6, which was certified by Connecticut General Life Insurance
Company, the trustee of the Plan, except for comparing the information with the
related information included in the financial statements and supplemental
schedule. 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
year ended December 31, 1999 that the information provided to the plan
administrator by the trustee is complete and accurate.

In our opinion, except for the effects of such adjustments, if any, as might
have been determined to be necessary had we performed procedures with respect to
the information summarized in Note 6, the financial statements referred to above
present fairly, in all material respects, the net assets available for benefits
of the plan as of December 31, 1999 and the changes in net assets available for
benefits for the year ended December 31, 1999 in conformity with generally
accepted accounting principles.

                    INDEPENDENT AUDITORS' REPORT (CONTINUED)

Our audit of the Plan's financial statements was conducted for the purpose of
forming an opinion on the basic financial statements taken as a whole. The
supplemental schedule on page 11 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.

The supplemental schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, except for
the effects on the Schedule of Assets Held For Investment Purposes of such
adjustments, if any, as might have been determined to be necessary had we
performed procedures with respect to the information as described in the second
preceding paragraph, are fairly stated in all material respects in relation to
the basic financial statements taken as a whole.

                       THE 401(k) SAVINGS PLAN FOR ACS GSG
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                DECEMBER 31, 1999

NOTE 1.  PLAN DESCRIPTION (CONTINUED)
FUNDING (CONTINUED)
Participating employees may contribute up to fifteen percent of covered
compensation through payroll deductions or the maximum amount permitted under
applicable Internal Revenue Service provisions. The Company matches each
participant's salary reduction contributions equal to 100% of the first 2% and
25% of the next 4% of such participant's compensation. In the prior year, the
Company made matching contributions of 25% up to 5% of participant's
compensation. The Company may change the rate of matching contributions at any
time by notifying participants in sufficient time to adjust their salary
reduction contributions prior to the start of the period in which the new
matching contribution percentage applies. In addition, the Company may make a
discretionary matching contribution to the Plan, based on a percentage of the
participant's salary reduction contributions.

ALLOCATION
Each participant's account is credited with the participant's and Company's
matching contribution and allocated to each participant's account upon receipt.
Investment income or loss is allocated daily based on the ratio of each
participant's account balance at the end of each day.

Company discretionary contributions are allocated among the participants on the
last day of the Plan year and in the same proportion that the entitled
participant's compensation for such Plan year bears to the total compensation of
all entitled participants.

VESTING
Employee contributions are 100% vested. An employee is credited with a year of
service for each fiscal year that the employee completes at least 1,000 hours of
service. Effective January 1, 1999, employer matching contributions vest over
the following schedule:

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                DECEMBER 31, 1999

NOTE 1.  PLAN DESCRIPTION (CONTINUED)
PARTICIPANT NOTES RECEIVABLE
Participants may borrow from their fund accounts a minimum of $1,000 up to a
maximum equal to the lesser of $50,000 or 50 percent of their account balance.
Loan transactions are treated as a transfer to (from) the investment fund and
from (to) the Participant Notes fund. Loan terms are not to exceed five years,
unless for the purpose of acquiring a principal residence, in which case the
loan may not be in excess of ten years. The balance in the participant's account
secures the loans. The interest rates are determined by the trustee using the
prime rate. An interest rate of 8.75% to 9.5% was charged during 1999. Principal
and interest is paid ratably through regular payroll deductions. Participant
notes receivable are valued at cost which approximates fair values.

TERMINATION
The Company's Board of Directors may terminate the Plan at any time. Upon
termination, the Board of Directors may elect to distribute to each participant,
or his or her beneficiary, the proportionate share of the Plan's assets as
determined by the individual account balances on the date of termination, or
continue the existence of the trust for the purpose of paying benefits as they
become due under the terms of the Plan. In addition, upon termination of the
Plan, participants' vested interest in employer contributions shall be 100%.

Upon termination of service, a participant may elect to receive either a
lump-sum amount equal to the value of his or her account, or one of various
installment payments available under the Plan.

FORFEITURES
Forfeitures are first used to reinstate previously forfeited account balances of
rehired former participants and any remaining forfeitures serve to reduce the
employer contributions. The Company reduced its matching contribution by
$165,585 of forfeitures for the year ended December 31, 1999.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
This summary of significant accounting policies of the Plan is presented to
assist in understanding the financial statements. The financial statements and
notes are representations of the Plan's administrator, who is responsible for
their integrity and objectivity. The accounting policies conform to generally
accepted accounting principles and have been consistently applied in the
preparation of the financial statements.

ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles requires the plan administrator to make estimates and
assumptions that affect certain reported amounts and disclosures, such as fair
value. Accordingly, actual results may differ from those estimates.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INVESTMENT VALUATION AND INCOME RECOGNITION
CIGNA Retirement and Investment Services holds the Plan's investments. The fair
value per unit/share is stated at quoted market prices. Purchases and sales of
securities are recorded on a trade-date basis. Interest income is recorded on
the accrual basis.

The Plan presents, in the statement of changes in net assets available for
benefits, the net appreciation (depreciation) in the fair value of its
investments which consists of the realized gains or losses and the unrealized
appreciation (depreciation) on those investments.

PAYMENT OF BENEFITS
Benefit payments are recorded when paid.

NOTE 3.  INCOME TAX STATUS
The Internal Revenue Service has determined by letter dated February 1, 1996,
that the Plan, as then designed, was in compliance with the applicable sections
of the IRC. The Plan has since been amended, however, the Plan administrator and
the Plan's tax counsel believe that the Plan is designed and is currently being
operated in compliance with the applicable requirements of the IRC. The Plan is
in the process of filing for an updated letter of determination. Therefore, no
provision for income taxes has been included in the Plan's financial statements.

NOTE 4.  TERMINATED EMPLOYEE INFORMATION
The Plan holds funds for 473 terminated employees with account balances totaling
$12,667,581 at December 31, 1999.

information held by a bank, trust company, or similar institution or an
