                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)



1.       BASIS OF PRESENTATION

         The consolidated financial statements include the accounts of
         Affiliated Computer Services, Inc. and its majority-owned subsidiaries.
         All material intercompany profits, transactions and balances have been
         eliminated. We are a Fortune 1000 Company based in Dallas, Texas with
         operations primarily in North America, as well as Central America,
         South America, Europe and the Middle East. We provide a full range of
         information technology services, including technology outsourcing,
         business process outsourcing and systems integration.

         The financial information presented should be read in conjunction with
         our consolidated financial statements for the year ended June 30, 2000.
         The foregoing unaudited consolidated financial statements reflect all
         adjustments (all of which are of a normal recurring nature) which are,
         in the opinion of management, necessary for a fair presentation of the
         results of the interim periods. The results for the interim periods are
         not necessarily indicative of results to be expected for the year.
         Certain financial statement items from the prior year have been
         reclassified to conform with current presentation.

2.       HEDGING ACTIVITIES AND COMPREHENSIVE INCOME

         In June 1998, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards No. 133, "Accounting for Derivatives
         and Hedging Activities". The statement requires us to record all
         derivatives on the balance sheet at fair value. If the derivative is a
         hedge, depending on the nature of the hedge, changes in the fair value
         of the derivatives are either recognized in earnings or are recognized
         in other comprehensive income until the hedged item is recognized in
         earnings. As of December 31, 2000, the fair market value of our
         interest rate hedge was $1.3 million and was recorded in other current
         assets.

         Statement of Financial Accounting Standards No. 130 "Reporting
         Comprehensive Income" establishes standards for reporting and display
         of comprehensive income and its components in the financial statements.
         The objective of SFAS 130 is to report a measure of all changes in
         equity of an enterprise that result from transactions and other
         economic events of the period other than transactions with owners.
         Comprehensive income is the total of net income and all other non-owner
         changes within a company's equity.

         The components of comprehensive income are as follows (in the
         thousands):

4.   NON-RECURRING ITEMS

     In the first quarter of fiscal 2001, we recorded a $12.8 million gain in
     other non-operating income related to the sale of a non-strategic minority
     investment in ACS Merchant Services, Inc. Also during the quarter, we
     recorded a $10.4 million charge in connection with the termination of
     certain hardware leases and disaster recovery contracts (reflected in rent,
     lease and maintenance expense) and a $2.1 million charge for non-recurring
     litigation costs and the writedown of property held-for-sale (reflected in
     other operating expense).

     In the second quarter of fiscal 2000, we recorded $3.0 million of
     accelerated expenses in connection with the consolidation of certain
     business process outsourcing operations. These expenses include
     approximately $2.6 million related to duplicate software and production
     facilities (reflected in rent, lease and maintenance expense), $0.2 million
     of unamortized leasehold improvements and write offs of excess equipment
     (reflected in depreciation and amortization expense) and $0.2 million for
     severance payments for reductions in staff (reflected in wages and benefits
     expense).

     In January 1999, we sold a business unit of an acquired company to
     CyberPlus Corporation ("Cyberplus"). As part of the consideration, we
     received a $3.2 million promissory note due March 2000 and 2.1 million
     warrants to purchase CyberPlus common stock. Given the financial
     uncertainty surrounding CyberPlus, the note receivable was fully reserved.
     In November 1999, CyberPlus obtained financing and repaid $3.0 million on
     the promissory note, resulting in a $3.0 million gain (reflected in other
     non-operating income).

5.   ACCUMULATED DEPRECIATION AND AMORTIZATION

     Property, equipment and software are stated net of accumulated depreciation
     of $186.2 million and $165.6 million at December 31, 2000 and June 30,
     2000, respectively. Additionally, goodwill and other intangibles are stated
     net of accumulated amortization of $96.6 million and $80.3 million at
     December 31, 2000 and June 30, 2000, respectively.

6.   ACQUISITIONS

     During December 2000, we acquired Business Resources Corporation, ("BRC"),
     a subsidiary of Tyler Technologies, Inc. for approximately $70 million in
     cash, which was funded by our existing credit facility. The acquisition was
     accounted for under the purchase method of accounting with assets acquired
     of $76.2 million and liabilities assumed of $6.2 million. BRC's results
     have been included in our consolidated financial statements from the
     effective date of the acquisition. BRC is a provider of outsourced records
     management, document workflow, imaging systems and services to state and
     local governments. BRC also provides real estate title plant services to
     title companies.

7.   SEGMENT INFORMATION

     Based on the criteria set forth in Statement of Financial Accounting
     Standard No. 131, "Disclosure about Segments of an Enterprise and Related
     Information," we have two reportable segments: commercial and federal
     government. Certain reclassifications have been made to the segment
     disclosure as the result of changes to our reporting structure. Prior year
     results have been restated for comparison purposes. The following is a
     summary of certain financial information by reportable segment (in
     thousands):

     4).

     (c) EBITDA consist of earnings before interest income, interest expense,
     other non-operating income and expense, income taxes, depreciation and
     amortization. EBITDA is not a measure of financial performance under
     generally accepted accounting principles and should not be considered in
     isolation or as an alternative to net income as an indicator of a company's
     performance or to cash flows from operating activities as a measure of
     liquidity.

     (d) Operating expense for quarter ended December 31, 1999 included $3.0
     million of accelerated expenses in connection with the consolidation of
     certain business process outsourcing operations (see Note 4).

               AFFILIATED COMPUTER SERVICES, INC. AND SUBSIDIARIES
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management's Discussion and Analysis of Financial Condition and Results of
Operations includes "forward-looking statements" within the meaning of Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. All statements, other than statements of historical facts, included in
this MD&A regarding our financial position, business strategy and plans and
objectives of our management for future operations are forward-looking
statements. These forward-looking statements rely on a number of assumptions
concerning future events and are subject to a number of uncertainties and other
factors, many of which are outside of our control, that could cause actual
results to materially differ from such statements. While we believe that the
assumptions concerning future events are reasonable, we caution that there are
inherent difficulties in predicting certain important factors, especially the
timing and magnitude of technological advances; the performance of recently
acquired businesses; the prospects for future acquisitions; the possibility that
a current customer could be acquired or otherwise be affected by a future event
that would diminish its information technology requirements; the competition in
the information technology industry and the impact of such competition on
pricing, revenues and margins; the degree to which business entities continue to
outsource information technology and business processes; uncertainties
surrounding budget reductions or changes in funding priorities or existing
government programs; and our ability, and the related cost of attracting and
retaining highly skilled personnel.

SIGNIFICANT DEVELOPMENTS

During the fourth quarter of fiscal 2000, we entered into a formal plan to
divest certain business units consisting of our ATM processing business and our
commercial staffing business due to the fact that these businesses were no
longer strategic to our long-term goal of providing information technology and
business process outsourcing services. By October 31, 2000, we had completed the
sale of and received the proceeds from these divestitures. During the first
quarter of fiscal 2001, we recorded a $12.8 million gain in other non-operating
income associated with the sale of a non-strategic minority investment in ACS
Merchant Services, Inc.

RESULTS OF OPERATIONS

The following table sets forth certain items from our consolidated statements of
income as a percentage of revenues:

COMPARISON OF THE QUARTER ENDED DECEMBER 31, 2000 TO THE QUARTER ENDED
DECEMBER 31, 1999

The divested units contributed $74.6 million in revenue in the second quarter of
fiscal 2000. Excluding the divested units, revenues increased 25% from $401.4
million to $500.9 million for the second quarter of fiscal 2001. More than half
of the increase, or 14%, was derived from internal growth. Excluding the
revenues from the divested units, revenues from our commercial segment increased
$66.2 million, or 27%. Revenue growth in the commercial segment was primarily
due to new signings in state Medicaid and welfare benefit program management, as
well as information technology contract signings. Revenues from our federal
government segment increased $33.3 million, or 22%, over the prior year quarter
primarily due to the acquisition of Intellisource in the fourth quarter of
fiscal 2000.

Included in the operating expenses in the second quarter of fiscal 2000 was $3.0
million of accelerated expenses related to the consolidation of certain business
process outsourcing operations (see Note 4). Excluding this non-recurring
charge, operating margins increased 1.1% from 10.2% to 11.3% as a result of the
divestiture program completed in the first quarter. Services and supplies
decreased as a percentage of revenue from 31.6% to 30.3% due to the divestiture
of the ATM processing business, which had a large component of interchange fees
paid to ATM distributors.

Other non-operating income for the second quarter of fiscal 2000 included the
recognition of a $3.0 million gain on the collection of a fully reserved note
receivable from the sale of a business unit in fiscal 1999 (see Note 4).
Excluding this non-recurring gain, other non-operating income decreased by $0.6
million.

Our effective tax rate of approximately 39.5% in the second quarter of fiscal
2001 exceeded the federal statutory rate of 35%, due primarily to the
amortization of certain acquisition-related costs that are non-deductible for
tax purposes, plus the net effect of state income taxes.

COMPARISON OF THE SIX MONTHS ENDED DECEMBER 31, 2000 TO THE SIX MONTHS ENDED
DECEMBER 31, 1999

Excluding revenues related to the divested units ($7.5 million and $154.3
million for the six months ended December 31, 2000 and 1999 respectively),
revenue increased $202.6 million, or 26% over the prior year from $769.4 million
to $972.0 million. Revenues from our commercial segment increased, excluding the
divested units, $132.1 million, or 28%, due to acquisitions as well as signings
of new customer contracts in state Medicaid and Welfare benefit program
management and information technology. Revenues in our federal government
segment increased $70.5 million, or 24%, primarily as a result of the
acquisition of Intellisource in the fourth quarter of fiscal year 2000.

Excluding the $12.5 million and $3.0 million in non-recurring charges in the
first six months of fiscal years 2001 and 2000, respectively (see Note 4),
operating margins increased 1.2% from 10.2% to 11.4% in fiscal 2001 as a result
of the completed divestiture program announced in the fourth quarter of fiscal
2000. Wages and benefits as a percentage of revenue increased from 43.1% to
43.8% as a result of the divestitures, which had a smaller component of wages
and benefit expense, and our continued focus on delivering business process
outsourcing services, which has a larger component of wages and benefits.
Services and supplies as a percentage of revenue decreased from 30.7% to 28.7%
as a result of the divestiture of the ATM processing business, which had a large
component of interchange fees paid to ATM distributors. After adjusting for the
non-recurring charges of $10.4 million in fiscal 2001 and $2.6 million in fiscal
2000, rent, lease and maintenance expense remained relatively constant.

Other non-operating income includes non-recurring gains of $12.8 million and
$3.0 million in the six months ended December 31, 2000 and 1999, respectively
(see Note 4). Excluding these gains, other non-operating income decreased as a
percentage of revenue from 0.3% to 0.2%.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 2000, we had cash and cash equivalents totaling $14.2 million
compared to $44.5 million at June 30, 2000. Included in the cash balances at
December 31, 2000 and June 30, 2000 were $12.8 million and $22.3 million,
respectively, of restricted cash held on behalf of governmental customers.
Working capital decreased to $269.4 million at December 31, 2000 from $413.6
million at June 30, 2000 due primarily to the collection of proceeds from
divestitures and the subsequent paydown of long-term debt.

Cash flow from operations was $7.4 million for the six months ended December 31,
2000. However, during the first quarter of fiscal 2001, we paid approximately
$48.7 million in income taxes related to the net gain from our divestiture
activity and approximately $10.4 million of non-recurring lease termination
charges, which are included in cash flows from operations. After adjusting for
these items, our net cash provided by operating activities would have been
approximately $66.5 million for the six months ended December 31, 2000. Cash
flow from investing activities was $78.7 million primarily due to the collection
of proceeds from divestitures offset by the acquisition of BRC in the second
quarter of fiscal 2001. Net cash used in financing activities was $116.4
million, which was the result of credit facility paydowns from the divestiture
proceeds less the borrowing for the BRC acquisition.

<PAGE>   12


In order to manage interest costs and exposure to changing interest rates, we
hold two interest rate hedges initiated in December 1998 and expiring in
December 2001. Each hedge is structured such that we pay a fixed rate of
interest of 4.54% and receive a floating rate of interest based on one month
LIBOR. The notional amount of the two hedges totals $100,000,000 and the fair
market value of the two hedges at December 31, 2000 was approximately $1.3
million, which is recorded in other current assets (see Note 2). The fair value
of each interest rate hedge reflects termination cash value.

Management believes that available cash and cash equivalents, together with cash
generated from operations and available borrowings under our credit facility,
will provide adequate funds for our anticipated internal growth needs, including
working capital expenditures. Our management also believes that cash provided by
operations will be sufficient to satisfy all existing debt obligations as they
become due. However, we intend to continue our growth through acquisitions and
we regularly evaluate potential acquisition candidates, which acquisitions could
require significant commitments of capital. In order to pursue such
opportunities, we may be required to incur debt or to issue additional
potentially dilutive securities in the future. No assurance can be given as to
our future acquisitions and expansion opportunities and how such opportunities
will be financed.

NEW ACCOUNTING STANDARDS

In December 1999, the Securities and Exchange Commission issued Staff Accounting
Bulletin 101, "Revenue Recognition in Financial Statements". SAB 101 provides
guidance on the recognition, presentation and disclosure of revenue in financial
statements and required adoption no later than the fourth quarter of fiscal
2001. We do not believe the adoption of SAB 101 will have a material impact on
our future earnings and financial position.


                                     PART II

ITEM 1. LEGAL PROCEEDINGS

On December 16, 1998, a state district court in Houston, Texas entered final
judgment against us in a lawsuit brought by twenty-one former employees of
Gibraltar Savings Association and/or First Texas Savings Association
(collectively, "GSA/FTSA"). The GSA/FTSA employees alleged that they were
entitled to the value of 401,541 shares of our stock pursuant to options issued
to the GSA/FTSA employees in 1988 in connection with a former data processing
services agreement between GSA/FTSA and us. The judgment against us was for
approximately $17,000,000, which includes attorneys' fees and pre-judgment
interest, but excludes additional attorneys' fees of approximately $850,000
which could be awarded in the event the plaintiffs are successful upon appeal
and final judgment. We continue to believe that we have a meritorious defense to
all or a substantial portion of the plaintiffs' claims. We filed our appeal of
the judgment on March 15, 1999 and are vigorously pursuing the appeal. The
plaintiffs also filed a notice of appeal and are pursuing their appeal. Should
the proceedings not be favorably resolved on appeal, we would be subject to a
charge equal to the amount of any final judgment, fees and interest awarded in
favor of the plaintiffs.

Government contracts are subject to review and audit by various governmental
authorities in the normal course of our business. Cost audits have been
completed through fiscal 1998 for a majority of the federal government business
operations. In management's opinion, any such reviews and the results of cost
audits for subsequent fiscal years will not have a material effect on our
financial position or results of operations.

We are subject to certain other legal proceedings, claims and disputes which
arise in the ordinary course of business. Although we cannot predict the
outcomes of these legal proceedings, management does not believe these actions,
in the aggregate, will have a material adverse effect on our financial position,
results of operations or liquidity.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

On October 26, 2000, we held our 2000 annual meeting of stockholders, at which
meeting our stockholders were asked to vote on the following proposals: (i)
elect two directors to the Board ("Proposal 1") and (ii) approve the
performance-based incentive compensation for our executive officers ("Proposal
2"). The results of the votes on such proposals were as follows:

ITEM 5.  OTHER INFORMATION

On February 14, 2001, we filed a Certificate of Correction of our Second Amended
and Restated Certificate of Incorporation to remove a provision establishing a
classified Board of Directors. The provision had been the subject of a vote at
a stockholders meeting held on December 16, 1997, after which the amendment was
filed with the Delaware Secretary of State. While the proposed amendment
received the approval of more than 80% of the voting shares present and voting
on the measure, it failed to receive the required approval of 80% of our total
outstanding voting stock. We filed the Certificate of Correction promptly upon
determining that the required approval was not obtained. Our current directors,
who with one exception were directors at the time of the prior amendment,
have served and will continue to serve until their successors are duly elected
or appointed.
