                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

            For the Quarters Ended March 31, 2000 and March 31, 1999


1. BASIS OF PRESENTATION

The information furnished reflects all adjustments which, in the opinion of the
Company, are necessary to present fairly its consolidated financial position and
the results of its operations and changes in financial position for the periods
indicated.

Reference is made to the Company's annual financial statements for the year
ended December 31, 1999, for a description of the accounting policies, which
have been continued without change. Also refer to the footnotes with those
annual statements for additional details of the Company's financial condition,
results of operations and changes in cash flows. The details in those notes have
not changed except as a result of normal transactions in the interim.

2. EARNINGS PER SHARE

Basic Earnings Per Share ("EPS") is based on the weighted average number of
common shares outstanding without consideration of common stock equivalents.
Diluted earnings per share is based on the weighted average number of common and
common equivalent shares outstanding, except the three month period ended March
31, 2000 where the effect would have been antidilutive. The calculation takes
into account the shares that may be issued upon exercise of stock options,
reduced by the shares that may be repurchased with the funds received from the
exercise, based on the average price during the year.

In accordance with SFAS No.128, the table below presents both basic and diluted
earnings per share:

17.2%. The E-Solutions Group increased to $33.4 million in the first quarter of
2000 from $20.2 million in the first quarter of 1999, an increase of $13.2
million or 65.3%. IT Services revenues, including Year 2000 revenues, decreased
to $80.9 million in the first quarter of 2000 from $117.9 million in the first
quarter of 1999, a decrease of $37.0 million or 31.4%. Year 2000 services
revenues decreased to $0.5 million in the first quarter of 2000 from $18.0
million in the first quarter of 1999, a decrease of $17.5 million. The Company's
Year 2000 business accounted for 0.4% of total revenues in the first quarter of
2000 versus 13.0% of total revenues in the first quarter of 1999. As
anticipated, the decline in Year 2000 business is reflective of the completion
of code remediation assignments for major customers. IT Services revenues,
excluding Year 2000 services, decreased to $80.5 million in the first quarter of
2000 from $99.9 million in the first quarter of 1999, a decrease of $19.4
million.

DIRECT COSTS. Direct costs decreased to $83.0 million in the first quarter of
2000 from $90.7 million in the first quarter of 1999. Gross margin decreased to
27.4% in the first quarter of 2000 from 34.3% in the first quarter of 1999. The
decrease in gross margin was primarily due to a decrease in the Company's higher
margin Year 2000 business and significant investments in the E-Solutions
business. The Company's margins are subject to fluctuations due to a number
of factors, including the level of salary and other compensation
necessary to attract and retain qualified technical personnel.

SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative
expenses increased to $33.2 million in the first quarter of 2000 from $29.9
million in the comparable 1999 period. As a percentage of revenues, selling,
general and administrative expenses increased to 29.0% of revenues in the first
quarter of 2000 from 21.7% of revenues in the first quarter of 1999.

INCOME FROM OPERATIONS. Operating margins decreased to a loss of 3.2% in the
first quarter 2000 from a profit of 11.8% in the comparable 1999 period. This
decrease was primarily due to the Y2K revenue decline and its related impact
on the buying habits of our customers, along with investments in the
E-Solutions business in 2000. The Company's business is labor-intensive and,
as such, is sensitive to inflationary trends. This sensitivity applies to
client billing rates, as well as to payroll costs.

OTHER INCOME/EXPENSE. Other income/(expense) decreased to ($0.3) million in
the first quarter of 2000 compared to other income of $0.3 million in the
first quarter of 1999. This decrease in other income was primarily the result
of decreased interest income.

PROVISION FOR INCOME TAXES. The effective tax rate for Federal, state and local
income taxes was 43.0% for the first quarter of 2000. For the comparable 1999
period, the rate was 42.5%.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
            For the Quarters Ended March 31, 2000 and March 31, 1999


NET INCOME/LOSS. Net loss for the first quarter of 2000 was $2.2 million, or
$0.07 loss per diluted share compared to net income of $9.5 million, or $0.30
earnings per diluted share for the first quarter of 1999, a decrease of $11.7
million.

LIQUIDITY AND CAPITAL RESOURCES. At March 31, 2000, the Company had $128.7
million in working capital, of which $19.1 million was cash, cash equivalents
and short-term investments. There was $25.0 million in borrowings outstanding
against one of the Company's bank lines of credit.

Net cash used by operating activities in the first three months of 2000 was $8.6
million, consisting primarily of a decrease in accounts payable and the net loss
for the quarter. During the first three months of 1999, net cash used in
operating activities was $28.4 million, consisting primarily an increase in
accounts receivable, offset in part by net income. The significant increase in
accounts receivable during the first three months of 1999 was primarily
attributable to delays in billing to customers, resulting from the
implementation of an enterprise-wide information system.

Net cash used in investing activities in the first three months of 2000 was $0.5
million, consisting of purchases of equipment. During the first three months of
1999, cash provided by investing activities was $4.6 million, consisting of the
sales of short-term investments offset in part by the purchase of equipment.

Net cash provided by financing activities was $11.7 million for the first three
months of 2000, primarily consisting of borrowings against the Company's line of
credit. For the first three months of 1999, net cash used in financing
activities was $5.4 million, consisting primarily of the repurchase of 510,000
shares of the Company's common stock.

At March 31, 2000, the Company had a current ratio position of 2.7 to 1. The
Company believes that its cash and cash equivalents and short-term investments,
lines of credit and internally generated funds will be sufficient to meet its
working capital needs through 2000.
