management, all adjustments (consisting only of normal recurring adjustments)
necessary for a fair statement of the financial position, results of operations
and cash flows for the interim periods presented have been made. Certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles ("GAAP")

Additional paid-in-capital increased by $115,409 from December 31, 1998 to March
31, 1999. The components of the increase include a $109,924 increase due to the
Company's initial public offering ("IPO") and a $5,262 increase due to income
tax benefits resulting from employee options exercised during the period.

At March 31, 1999, there were 85,702,020 shares of the Company's Class A Common
Stock outstanding, 934,320 shares of the Company's Class B Common Stock
outstanding and 2,780,965 Class A shares held in treasury. At December 31, 1998,
there were 77,126,048 shares of the Company's Class A Common Stock outstanding,
934,320 shares of the Company's Class B Common Stock outstanding and 3,940,302
Class A shares held in treasury. The increase in common stock was due primarily
to 7,475,000 shares issued in the IPO.

NOTE 5: TERMINATION OF MAJOR CONTRACT

The Company provides services for East Midlands Electricity (IT) Limited
(together with its parent company, East Midlands Electricity plc, "EME") under
an Information Technology Services Agreement initially entered into on April 8,
1992, as amended. Under the terms and conditions of this agreement, EME has the
right to terminate its relationship with the Company following a change in
control of EME. In July 1998, PowerGen plc acquired EME from Dominion Resources,
Inc. During the first quarter of 1999, PowerGen plc and EME exercised this
right. The termination takes effect in October 1999. The Company will receive
termination payments and incur termination costs in accordance with the terms of
the agreement. The Company does not believe this event will have a material
adverse impact on 1999 financial position or results of operations.


NOTE 6: RELOCATION CHARGE

In March 1999, the Company formulated a plan for relocating certain general and
administrative support groups from Reston, Virginia to the corporate
headquarters in Dallas, Texas. This plan was announced to affected employees in
April 1999. The Company estimates the total cost of this relocation to be
between $2,000 and $3,000, and anticipates that the transition will be
substantially complete by the end of 1999. Approximately $650 of related costs
were accrued in the first quarter of 1999.

ITEM 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS

Comparison of the three months ended March 31, 1999 and 1998

         Total revenue increased in the three months ended March 31, 1999 by 
28.2% to $274.4 million from $214.1 million in the three months ended March 31,
1998 due to increases of $22.9 million from several new contracts entered into
after the first quarter of 1998, $28.7 million from UBS (the Company's largest
customer) and $8.7 million from other new and existing business.

         Domestic revenue grew by 30.7% in the first quarter of 1999 to $182.3
million from $139.5 million in the first quarter of 1998, and increased slightly
as a percentage of total contract revenue to 66.5% from 65.2% over the same
period.

         Non-domestic revenue, consisting of European and Asian operations, grew
by 23.5% in the first quarter of 1999 to $92.1 million from $74.6 million in the
first quarter of 1998, and decreased as a percentage of total contract revenue
to 33.5% from 34.8%. The largest components of European operations were the
United Kingdom, where revenue increased 10.6% to $59.4 million in the first
quarter of 1999 from $53.7 million in the first quarter of 1998, and
Switzerland, where revenue increased 51.1% to $13.7 million in the first quarter
of 1999 from $9.1 million in the first quarter of 1998. Asian operations
represented $4.8 million, or 1.8%, and $2.4 million, or 1.1%, of total revenue
for the three months ended March 31, 1999 and 1998, respectively.

         Direct cost of services increased in the first quarter of 1999 by 23.8%
to $210.3 million from $169.9 million over the same period of 1998, due
primarily to continued growth in the Company's business. Gross margin as a
percentage of revenue increased to 23.4% from 20.6% for the first quarter of
1999 compared to the first quarter of 1998, due primarily to significant
improvements in profitability on short-term projects.

         Selling, general, and administrative expenses ("SG&A") increased in the
first quarter of 1999 by 26.2% to $41.4 million from $32.8 million over the same
period of 1998, but decreased slightly as a percentage of total contract revenue
to 15.1% from 15.3%. While the Company continued to control its normal general
and administrative spending during the first quarter of 1999, there were $3.5
million of charges for departmental relocations, special payroll tax accruals
and litigation-related costs, collectively increasing first quarter of 1999 SG&A
as a percentage of revenue by 1.3 percentage points.

         As a result of the factors noted above, operating income increased in
the first quarter of 1999 to $22.7 million from $11.4 million in the first
quarter of 1998, and operating margin (operating income as a percentage of
contract revenue) increased to 8.3% from 5.3%.

         Interest income increased to $2.4 million in the first quarter of 1999
compared to $0.8 million in the prior year period due primarily to a significant
increase in cash and cash equivalents, resulting from $110.0 million of net
proceeds received from the Company's initial public offering ("IPO") of common
stock on February 5, 1999.

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS


         Equity in earnings of unconsolidated affiliates increased in the
quarter ended March 31, 1999 to $2.2 million from $1.0 million during the
quarter ended March 31, 1998 due to improved results at Systor AG ("Systor"), a
subsidiary of UBS, and at HCL Perot Systems N.V. ("HPS"), a software development
joint venture based in India. The equity in earnings for Systor increased to
$0.8 million from $0.4 million and equity in earnings for HPS increased to $1.4
million from $0.6 million for the quarters ended March 31, 1999 and 1998,
respectively. Other income/(expense) in the first quarter of 1998 of $2.6
million was principally due to a $3.0 million gain on the sale of the Company's 
limited partnership interest in a venture capital fund in 1998. 

         The decrease in the effective tax rate for the first quarter of 1999 to
40.0% from 42.5% for the first quarter of 1998 was due primarily to lower 
overall foreign taxes in 1999 and lower 1999 goodwill amortization.

         Net income increased 80.0% in the first quarter of 1999 to $16.2
million from $9.0 million in the first quarter of 1998 and net income margin
increased to 5.9% from 4.2%.

LIQUIDITY AND CAPITAL RESOURCES

         During the three months ended March 31, 1999, cash and cash equivalents
increased 55.8% to $225.8 million from $144.9 million at December 31, 1998
primarily due to the proceeds from the Company's IPO.

         Net cash used in operating activities was $23.5 million for the first
quarter of 1999 compared to net cash provided by operating activities of $26.2
million for the first quarter of 1998. The decrease was due primarily to a $36.0
million decrease in current liabilities such as accrued liabilities and accrued
compensation and a $21.7 million increase in current assets consisting primarily
of increased accounts receivable.

         Net cash used in investing activities was $5.0 million for the first
quarter of 1999 compared to net cash provided by investing activities of $0.3
million for the first quarter of 1998. Cash paid for property, equipment and
software was $5.0 million for both periods, but the expenditures in 1998 were
offset by $5.2 million in proceeds from the sale of the Company's limited
partnership interest in a venture capital fund.

         For the three months ended March 31, 1999, net cash provided by
financing activities was approximately $113.9 million, compared to $0.1 million
for the three months ended March 31, 1998. This increase was due primarily to
proceeds of $110.0 million from the Company's IPO. In addition, the Company
received $4.1 million in proceeds from the issuance of treasury stock in the
first quarter of 1999 compared to $0.5 million in the first quarter of 1998 in
connection with the increased exercise of stock options by employees during the
period.

         The Company routinely maintains cash balances in certain European and
Asian currencies to fund operations in those regions. During the first quarter
of 1999, foreign exchange rate fluctuations adversely impacted the Company's
non-domestic cash balances by $4.4 million, as British pounds, Swiss francs and
Netherlands guilders all weakened against the U.S. dollar. The Company's foreign
exchange policy does not call for hedging foreign exchange exposures that are 
not likely to impact net income or working capital.

         The Company has no committed line of credit or other borrowings and
anticipates that cash flows from operating activities and proceeds from its IPO
will provide sufficient funds to meet its needs for the foreseeable future. From
time to time, the Company may consider repurchasing its Class A Common Stock
depending on price and availability and alternative uses for its financial
resources.

YEAR 2000 ISSUES

         The following statements and all other statements made in this
quarterly report or the accompanying financial statements with respect to the
Company's Year 2000 processing capabilities or readiness are "Year 2000
Readiness Disclosures" in conformance with the Year 2000 Information and
Readiness Disclosure Act of 1998 (Public Law 105-271, 112 Stat. 2386).

         Some computers, software, and other equipment includes computer code in
which calendar year data is abbreviated to only two digits. As a result of this
design decision, some of these systems could fail to operate or fail to produce
correct results if "00" is interpreted to mean 1900, rather than 2000. These
problems are widely expected to increase in frequency and severity as the year
2000 approaches, and are commonly referred to as the "Year 2000 Problem".

         Assessment. The Year 2000 Problem affects computers, software, and
other equipment used, operated, or maintained by the Company for itself and its
customers. Accordingly, the Company is currently assessing the potential impact
of, and costs of remediating, the Year 2000 Problem for its internal systems
and, where the Company is contractually obligated to remediate the Year 2000
Problem, on systems operated or maintained on behalf of its customers. In
addition, the Company is performing assessments for some other customers.

         For each of these areas, the Company is using a methodology involving
the following six phases: Discovery, Assessment, Planning, Remediation, Testing,
and Implementation. At March 31, 1999, the discovery, assessment, and planning
phases were substantially complete for most program areas. The target completion
dates for priority items by remaining steps are as follows: Remediation -
September 1999; Testing - September 1999; and Implementation - September 1999.

         Because the Company's business involves the assessment, implementation,
and operation of computer systems, the Company has not generally obtained
verification or validation by independent third parties of its processes to
assess Year 2000 Problems, its corrections of Year 2000 Problems, or the costs
associated with these activities. However, the Company's Year 2000 project team
is reviewing the project plans prepared by each of the Company's business units
and monitoring their methods and progress against those plans.

         Internal Infrastructure. The Company believes that it has identified
most of the major computers, software applications, and related equipment used
in connection with its internal operations that must be modified, upgraded, or
replaced to minimize the possibility of a material disruption to its business.
The Company has commenced the process of modifying, upgrading, and replacing
major systems that have been assessed as adversely affected, and expects to
complete this process before the occurrence of any material disruption of its
business.

         Systems Other than Information Technology Systems. In addition to
computers and related systems, the operation of office and facilities equipment,
such as fax machines, photocopiers, telephone switches, security systems,
elevators, and other common devices may be affected by the Year 2000 Problem.
The Company is currently assessing the potential effect of, and costs of
remediating, the Year 2000 Problem on its office and facilities equipment.

         The Company estimates the total cost to the Company of completing any
required modifications, upgrades, or replacements of these internal systems to
be approximately $0.8 million, almost all of which the Company believes will be
incurred during 1999. This estimate is being monitored and will be revised as
additional information becomes available. In addition, the Company recorded a
$1.8 million charge in direct cost of services for the three months ended March
31, 1999 to address Year 2000 exposures for certain client contracts.

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS


         Based on the activities described above, the Company does not believe
that the Year 2000 Problem will have a material adverse effect on the Company's
business or results of operations. In addition, the Company has not deferred any
material information technology projects as a result of its Year 2000 Problem
activities.

         Client Systems. During 1997, the Company initiated assessments of the
effect of the Year 2000 Problem on computers, software, and other equipment it
operates or maintains for its customers, and its obligations to modify, upgrade,
or replace these systems. As part of this process, the Company has been
estimating the costs and revenues to the Company for performing any necessary
services. The Company is monitoring and updating this assessment on an ongoing
basis. The estimated cost associated with making clients' systems Year 2000
compliant for contracts where the Company is obligated to perform these services
at its expense has been and will be treated as a contract cost and is included
in the estimate of total contract costs for the respective contract under the
Company's revenue recognition policy. The Company believes that its clients have
been deferring other projects pending resolution of their Year 2000 Problems.

         Suppliers. The Company has initiated communications with third party
suppliers of the major computers, software, and other equipment used, operated,
or maintained by the Company for itself or its customers to identify and, to the
extent possible, to resolve issues involving the Year 2000 Problem. However, the
Company has limited or no control over the actions of these third party
suppliers. Thus, while the Company expects that it will be able to resolve any
significant Year 2000 Problems with these systems, there can be no assurance
that these suppliers will resolve any or all Year 2000 Problems with these
systems before the occurrence of a material disruption to the business of the
Company or any of its customers. Any failure of these third parties to timely
resolve Year 2000 Problems with their systems could have a material adverse
effect on the Company's business, financial condition, and results of operation.

         Most Likely Consequences of Year 2000 Problems. The Company expects to
identify and resolve all Year 2000 Problems that could materially adversely
affect its business operations. However, management believes that it is not
possible to determine with complete certainty that all Year 2000 Problems
affecting the Company or its clients have been identified or corrected. The
number of devices that could be affected and the interactions among these
devices are simply too numerous. In addition, no one can accurately predict how
many Year 2000 Problem-related failures will occur or the severity, duration, or
financial consequences of these perhaps inevitable failures. As a result,
management expects that the Company will likely suffer the following
consequences:

o    a significant number of operational inconveniences and inefficiencies for
     the Company and its clients that will divert management's time and
     attention and financial and human resources from its ordinary business
     activities;

o    a lesser number of serious system failures that will require significant
     efforts by the Company or its clients to prevent or alleviate material
     business disruptions;

o    several routine business disputes and claims for pricing adjustments or
     penalties due to Year 2000 Problems by clients, which will be resolved in
     the ordinary course of business; and

o    a few serious business disputes alleging that the Company failed to comply
     with the terms of its contracts or industry standards of performance, some
     of which could result in litigation or contract termination.

         Contingency Plans. The Company is currently developing contingency
plans to be implemented if its efforts to identify and correct Year 2000
Problems affecting its internal systems are not effective. The Company expects
to complete its contingency plans by the end of May 1999. Depending on the
systems affected, these plans could include accelerated replacement of affected
equipment or software, short-to medium-term use of backup sites, equipment and
software, increased work hours for Company personnel or use of contract
personnel to correct on an accelerated schedule any Year 2000 Problems that
arise or to provide manual workarounds for information systems, and similar
approaches. If the Company is required to implement any of these contingency
plans, it could have a material adverse effect on the Company's financial
condition and results of operations.

         The Company is also developing contingency plans for certain clients
where such plans are contractually required or are otherwise appropriate to be
developed. In most cases, these contingency plans are being developed jointly by
the Company and its clients. Depending on the systems affected, these plans
could include accelerated replacement of affected equipment or software, short-
to medium-term use of backup sites, equipment and software, increased work hours
for company personnel or use of contract personnel to correct on an accelerated
schedule any Year 2000 Problems that arise or to provide manual workarounds for
information systems, and similar approaches. If the Company is required to
implement any of these contingency plans, it could have a material adverse
effect on the Company's financial condition and results of operations.

         Disclaimer. The discussion of the Company's efforts, and management's
expectations, relating to Year 2000 compliance are forward-looking statements.
The Company's ability to achieve Year 2000 compliance and the level of
incremental costs associated therewith, could be adversely impacted by, among
other things, the availability and cost of programming and testing resources,
vendors' ability to modify proprietary software, and unanticipated problems
identified in the ongoing compliance review.

IMPACT OF EUROPEAN MONETARY UNION

         Effective January 1, 1999, the European Union adopted economic and
monetary union in Europe, resulting in the introduction of a single currency
called the EURO. The Company is currently assessing the potential effects of,
and costs of adopting, the EURO conversion for its internal systems and, where
the Company is contractually obligated to take these steps, on systems operated
or maintained on behalf of its clients. For each of these areas, the Company is
using the six phase methodology described above for the Year 2000 Problem. The
Company has substantially completed the discovery phase and the EURO conversion
is not expected to have a material effect on the Company's operations, financial
condition or results of operations.

         The discussion of the Company's efforts, and management's expectations,
relating to the EURO conversion are forward-looking statements. The Company's
ability to adapt for the EURO conversion and the level of incremental costs
associated therewith could be adversely affected by, among other things, the
availability and cost of programming and testing resources and unanticipated
problems identified in the ongoing conversion review.

                                    FORM 10-Q
                      For the Quarter Ended March 31, 1999


PART II: OTHER INFORMATION


ITEM 1.  LEGAL PROCEEDINGS

         The Company is, from time to time, involved in various litigation
matters arising in the ordinary course of its business. The Company believes
that the resolution of currently pending legal proceedings, either individually
or taken as a whole, will not have a material adverse effect on the Company's
consolidated financial position or results of operations.

         On October 19, 1998, the Robert Plan Corporation ("Robert Plan") filed
a complaint, which was subsequently amended, in New York state court against the
Company and Ross Perot in connection with a September 1, 1990 contract under
which the Company provides data processing and software development needs for
some of Robert Plan's operations. The complaint, as amended, alleges breach of
the 1990 contract, misappropriation of Robert Plan's proprietary information and
business methods in connection with an imaging system, breach of warranty, and
similar claims relating to the contract. Although the complaint seeks
substantial monetary awards and injunctive relief, the 1990 contract
substantially limits each party's liability except in limited circumstances,
including for "wanton or willful misconduct." Accordingly, Robert Plan has
alleged that the Company has acted in a "wanton" and "willful" fashion, even
though Robert Plan has used and continues to use the services of the Company
under the 1990 contract. The Company believes that it has meritorious defenses
to Robert Plan's claims and intends to vigorously defend the lawsuit. The
Company does not believe that the outcome of this litigation will have a
material adverse effect on the Company.


ITEM 2:  CHANGES IN SECURITIES

         On February 1, 1999, the Securities and Exchange Commission declared

                                                   ===========


         None of the above expenses were paid either directly or indirectly to
