Note 1 - Basis of Presentation

The accompanying unaudited consolidated financial statements include the
accounts of Federal Data Corporation and its wholly-owned subsidiaries
(collectively, the Company) and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and
note disclosures normally included in the annual financial statements, prepared
in accordance with generally accepted accounting principles, have been condensed
or omitted pursuant to those rules and regulations, although the Company
believes that the disclosures made are adequate to make the information
presented not misleading.

In the opinion of management, the accompanying unaudited consolidated financial
statements reflect all necessary adjustments and reclassifications (all of which
are of a normal, recurring nature) that are necessary for fair presentation for
the periods presented. It is suggested that these unaudited consolidated
financial statements be read in conjunction with the consolidated financial
statements and the notes thereto included in the Company's latest annual report
to the Securities and Exchange Commission on Form 10-K 405 for the year ended
December 31, 1997.

The results of operations for the three month period ended March 31, 1998, are
not necessarily indicative of the results to be expected for the full fiscal
year ending December 31, 1998.

All of the Company's direct and indirect wholly-owned subsidiaries have fully
and unconditionally guaranteed, on a joint and several basis, the Company's
obligations under its Senior Subordinated Notes. The Company is a holding
company with no assets or operations other than its investments in its
subsidiaries. The separate financial statements of the subsidiary guarantors are
not presented because the Company's management believes that such financial
statements are not material to investors.

Note 2 - Acquisitions

During the quarter ended June 30, 1997, the Company purchased all of the
outstanding shares of common stock of NYMA, Inc. (NYMA) and Sylvest Management
Systems Corporation (Sylvest) (collectively, the 1997 Acquisitions) for an
aggregate purchase price of $72,604. The agreements provide for additional
payments of up to $3,000 if certain operating objectives related to new business
activity are met. Such payments, if any, will be determined during the second
quarter of 1998 and accounted for as adjustments to the purchase price. NYMA is
a provider of high technology engineering and information technology services
under contracts with various United States Government (the Government) agencies
and subcontracts with large government contractors. Sylvest is a leading
reseller and technical services vendor supporting open systems architecture
within the federal marketplace.

In February and March 1998, the Company purchased all of the outstanding common
stock of R.O.W. Sciences, Inc. (R.O.W.) and Technical and Management Assistance,
Inc. (TMA) and also in March purchased all of the assets of Telos Information
Systems (TIS), a division of Telos Corporation, (collectively, the 1998
Acquisitions). The aggregate purchase price of the 1998 Acquisitions was
$32,675. The agreements also provide for additional cash payments up to $1,000
if certain revenue objectives are met. Such payments, if any, will be accounted
for as adjustments to the purchase price. The purchase prices for R.O.W. and TMA
are subject to adjustment based on an audit of the closing balance sheets. The
Company financed the 1998 Acquisitions principally through borrowings under its
existing line of credit facility. R.O.W. provides information technology and
health science research services to federal and commercial clients. TMA provides
software development services principally to the air traffic management function
within the


                                       6
<PAGE>

Federal Aviation Administration. TIS provides information technology and
engineering services principally to NASA and the Jet Propulsion Laboratory.

The Company recorded goodwill of $48,491 and $18,952 related to the 1997 and
1998 Acquisitions, respectively, and it is being amortized over fifteen years.
The purchase price of the acquisitions includes intangible assets of $10,701 and
$4,830 for the 1997 and 1998 Acquisitions, respectively. The intangible assets
represent contract backlog at the acquisition date and is recorded at the
present value of the projected pretax profits. The present value of the contract
backlog is being amortized over the remaining terms of the acquired contracts in
relation to the recognition of related contract revenue.

Condensed unaudited pro forma operating data which gives effect to all of the
acquisitions described above for the year ended December 31, 1997 and the three
months ended March 31, 1997 and 1998 is provided below. Such condensed unaudited
pro forma operating data has been prepared as if the acquisitions occurred as of
the beginning of the reporting period. The Company is currently conducting an
analysis of the allocation of the purchase price for the 1998 Acquisitions. The
preliminary purchase price allocation may change during the year ending December
31, 1998 as additional information concerning the net asset valuation is
obtained.

In the opinion of management, the condensed unaudited pro forma operating data
is not indicative of the actual results that would have occurred had the
acquisitions been consummated at the beginning of 1997 or at the beginning of
1998 or of future operations of the combined companies under the ownership and
management of the Company.

Note 3 - Recent Pronouncements

In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Standards No. 130, "Reporting Comprehensive Income" (SFAS No. 130).
SFAS No. 130 establishes standards for the reporting and presenting of
comprehensive income and its components (revenue, expenses, gains and losses) in
a full set of general-purpose financial statements. At March 31, 1998, there is
no impact on the Company's financial reporting as a result of its adoption of
SFAS 130.

Also in June 1997, the Financial Accounting Standards Board issued Statement of
Financial Standards No. 131, "Disclosures about Segments of an Enterprise and
Related Information" (SFAS No. 131). SFAS No. 131 establishes standards for the
manner in which public business enterprises report information about operating
segments and the related disclosures about products and services, geographic
area, and major customers. SFAS No. 131 is effective for financial statements
issued for fiscal years beginning after December 15, 1997. The Company is
currently reviewing what effect this standard will have on future reporting.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations.

EXCEPT AS EXPRESSLY INDICATED, THE FOLLOWING DISCUSSION DOES NOT GIVE EFFECT TO
THE PRE-ACQUISITION OPERATIONS OF NYMA, SYLVEST, R.O.W., TIS AND TMA
(COLLECTIVELY, THE ACQUISITIONS) OR INCLUDE PRO FORMA FINANCIAL INFORMATION.

Results Of Operations

Three Months Ended March 31, 1998 Compared With Three Months Ended March 31,
1997

Revenues

Revenues for the three months ended March 31, 1998 were $91.8 million, up $61.4
million or 201% over the comparable period of 1997. The Acquisitions accounted
for $51.4 million of the increase in revenue over the comparable period of 1997.
Revenue from equipment and software sales was $53.2 million, up $39.6 million or
292% over the comparable period of 1997. The Acquisitions accounted for $28.4
million of the increase in equipment and software sales revenue over 1997. The
remaining increase in revenue from equipment and software sales is principally
due to increased emphasis on the Company's sale of commercial off-the-shelf
(COTS) products. Revenue from maintenance and support services was $38.2
million, up $21.9 million or 134% over the comparable period of 1997. The
Acquisitions accounted for $22.9 million of the increase in maintenance and
support services revenue over the comparable period of 1997. This increase in
maintenance and support services revenue was partially offset by a reduction in
maintenance and support services revenue due to the expiration of an existing
Department of the Navy contract during the fourth quarter of 1997.

Cost of Sales and Services

Cost of sales and services for the three months ended March 31, 1998 was $79.2
million, up $55.7 million or 237% over the comparable period of 1997. The
Acquisitions accounted for $46.0 million of the increase in cost of sales and
services over the comparable period of 1997. Cost of sales and services in 1998
was 87% of sales and services revenues compared with 79% of sales and services
revenues for the comparable period of 1997. The decrease in the gross margin
percentage primarily relates to increased influence of the COTS products sold
through the Company's Systems & Technology Group including Sylvest, which
generally have lower gross margin percentages than product sales by the
Company's Systems Integration Group and Solutions Group, and the lower margins
on the cost plus fee business of NYMA, R.O.W., TIS and TMA.

Selling, General and Administrative Expense

Selling, general and administrative expense for the three month period ended
March 31, 1998 was $10.3 million, up $4.2 million or 69% over the comparable
period of 1997. The Acquisitions accounted for $4.3 million of the increase in
selling, general and administrative expenses over the comparable period of 1997.
Excluding the effect of the Acquisitions, selling, general and administrative
expense for the three month period ended March 31, 1998 was 15% of revenues,
compared with 20% in the comparable period of 1997. This decrease in selling,
general and administrative expense as a percent of revenue was due primarily to
economies of scale resulting from the increase in revenues.

Amortization of Goodwill and Intangible Asset

The excess of the cost of the Acquisitions over the fair value of identifiable
net tangible and intangible assets acquired was $67.4 million and is being
amortized on a straight-line basis over fifteen years. The present value of the
contract profits of $15.5 million acquired in the Acquisitions is being
amortized over the remaining terms of the acquired contracts in relation to the
recognition of related contract revenue. Amortization of goodwill and intangible
assets for the three months ended March 31, 1998 was $2.2 million.

Interest Expense

Interest expense for the three months ended March 31, 1998 was $3.6 million, up
$1.9 million, or 113% over the comparable period of 1997. Recourse interest
expense increased $2.2 million for the three months ended March 31,1998 over the
comparable period of 1997 primarily due to increased recourse debt used to
partially finance the Acquisitions. Interest expense on nonrecourse debt
declined $0.3 million for the three months ended March 31, 1998 from the
comparable period of 1997 due to a reduced level of capital leases. Interest
expense is expected to be higher in 1998 than in 1997, reflecting the higher
level of indebtedness to be outstanding for the full year, as a result of the
acquisitions of NYMA and Sylvest, and the additional indebtedness incurred to
finance the acquisitions of R.O.W., TIS and TMA.

Income Tax Benefit

The income tax benefit for the three month period ended March 31, 1998 is based
on an estimated annual effective rate, excluding expenses not deductible for
income tax purposes. Before giving effect to the Acquisitions, the effective tax
provision rate for the year ending December 31, 1998 is estimated to be 40%,
approximately the same rate recorded during the three months ended March 31,
1997. The Company believes that the nondeductibility of the additional
amortization of goodwill and the value related to contract backlog associated
with the NYMA and R.O.W. acquisitions will cause the annual effective tax rate
for 1998 to be higher than the annual effective tax rate in 1997.

Net Loss

Net loss for the three months ended March 31, 1998 was $2.5 million, a $2.0
million increase from the net loss of $0.5 million recorded in the comparable
period of 1997 based on the reasons discussed above.

Liquidity and Capital Resources

The Company's primary source of liquidity is cash provided by operations. The
Company's liquidity requirements generally vary seasonally with revenues, which
are generally higher in the third and fourth quarters of each fiscal year.
Historically, cash flow from the collection of accounts receivable from the
Government has generally been predictable and dependable. Cash and cash
equivalents were $0.0 million at March 31, 1998, down $6.3 million from December
31, 1997 primarily as a result of net cash flow from operating activities of
$0.3 million and net cash flows from financing activities of $24.7 million being
offset by net cash flow used in investing activities of $31.4 million. Net cash
flow from operating activities was primarily a result of decreases in accounts
receivable and other assets and liabilities of $13.2 million and $1.8 million,
respectively. The increased focus on COTS products sold through the Systems &
Technology Group used $3.9 million in cash to increase inventory over the
December 31, 1997 levels. In addition, cash was used to reduce accounts payable
and accrued expenses by $11.6 million. Net cash flow from financing activities
was $24.7 million for the three months ended March 31, 1998 primarily as a
result of net borrowings under the Company's working capital line of credit of
$28.9 million and issuance of term notes in connection with the R.O.W and TMA
acquisitions due in 2000 totaling $2.0 million. This cash was used, in part, to
repay and retire line of credit balances of acquired companies of $3.8 million.
Net cash used in investing activities amounted to $31.4 million for the three
months ended March 31, 1998, primarily as a result of the acquisition of R.O.W.,
TMA and TIS totaling $30.3 million and the purchases of property and equipment
totaling $1.0 million.

EBITDA represents the sum of loss before income tax benefit, net recourse
interest expense and depreciation and amortization. EBITDA is not a measure of
performance or financial condition under generally accepted accounting
principles, but is presented to provide additional information related to debt
service capability. EBITDA should not be considered in isolation or as a
substitute for other measures of financial performance or liquidity under
generally accepted accounting principles. While EBITDA is frequently used as a
measure of operations and the ability to meet debt service requirements, it is
not necessarily comparable to other similarly titled captions of other companies
due to the potential

inconsistencies in the method of calculation. The following presentation
