                             GRC INTERNATIONAL, INC.
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                     FOR THE QUARTER ENDED DECEMBER 31, 1999
                                   (unaudited)

(1)   Basis of Presentation. The consolidated condensed financial statements
      included herein have been prepared by the Company, without audit, pursuant
      to the rules and regulations of the Securities and Exchange Commission.
      Certain information and footnote disclosures normally included in
      financial statements prepared in accordance with generally accepted
      accounting principles have been condensed or omitted pursuant to such
      rules and regulations. The results of operations presented herein are not
      necessarily indicative of the results to be expected for a full year.
      Although the Company believes that all material adjustments (consisting
      only of normal recurring adjustments) necessary for a fair presentation of
      the interim periods presented are included and that the disclosures are
      adequate to make the information presented not misleading, these
      consolidated condensed financial statements should be read in conjunction
      with the consolidated financial statements and notes thereto included in
      the Company's Annual Report on Form 10-K for the fiscal year ended June
      30, 1999.

(2)   New Accounting Pronouncements. For the year ending June 30, 2001, the
      Company will be required to adopt SFAS 133, Accounting for Derivative
      Instruments and Hedging Activities. Management does not believe adoption
      of this Standard will have a material impact on its financial statements.

(3)   Debt. The Company maintains a $35 million revolving credit agreement
      effective August 27, 1999. The Company has both Prime and LIBOR (London
      Interbank Offered Rate) based borrowing options under the Credit
      Agreement. The interest accrued on LIBOR loans is based on a ratio of debt
      to cash flow. The current premium is 1.10% above the applicable LIBOR
      rate. The Company also pays a performance based commitment fee, which is
      currently 0.30% of the line of credit.

      Debt at December 31, 1999 and June 30, 1999 consisted of the following:

                                       December 31, 1999           June 30, 1999

(4)   Acquisition of Management Consulting and Research, Inc. Effective
      September 2, 1999, the Company acquired all of the outstanding stock of
      Management Consulting and Research, Inc. (MCR). The net purchase price of
      approximately $23 million was paid with 2 million shares of GRCI's common
      stock valued at approximately $16 million, and the remainder of
      approximately $7 million in net cash was financed through the new credit
      agreement. The resulting $20.8 million in goodwill is to be amortized over
      30 years. MCR provides professional services to the U.S. Government
      primarily in the areas of budget analysis, cost estimating and program
      management. MCR's revenues are approximately $30 million per year. The
      acquisition was accounted for using the purchase method of accounting and
      has been consolidated with GRC from the date of acquisition.

(5)   Segment Information. The Company adopted SFAS No. 131, "Disclosures about
      Segments of an Enterprise and Related Information" during fiscal 1999.
      SFAS No. 131 establishes standards for reporting information about
      operating segments and related disclosures about products and services,
      geographic areas and major customers.

      All of the Company's business relates to information technology consulting
      services. The chief operating decision-maker is provided information about
      the revenues generated by operating segment and utilizes income before
      interest and taxes as a measure of segment performance. The Company's
      services are delivered to clients primarily in the United States, and the
      Company's long-lived assets are located within the United States. Based on
      SFAS No. 131 criteria, the Company has two reportable operating segments;
      U.S. Federal Government and Commercial. Within the U.S. Federal Government
      segment are sales to the Company's largest customer, the Department of
      Defense ("DoD"). Revenues from the DoD represented 97% of total U.S.
      Government revenues in the first half of both fiscal 2000 and fiscal 1999.

(6)      Subsequent Event - On February 14, 2000, the Company executed a
definitive merger agreement with AT&T Corp. under which AT&T will commence a
cash tender offer to acquire all of the outstanding shares of the Company for
$15.00 per share. The Company's Board has received a fairness opinion on AT&T's
offer. The Boards of Directors of both companies have unanimously approved
the merger agreement. The tender offer will commence within seven business days
and is expected to conclude within approximately two months.

         The tender offer is subject to a majority of the Company's common stock
on a fully diluted basis being validly tendered and not withdrawn, the
expiration of the Hart-Scott-Rodino waiting period, and other customary
conditions. If a majority of the Company's shares are tendered in response to
the offer and the other conditions to the offer are satisfied or waived, a
subsiary of At&T will be merged into the Company, shares not purchased in the
offer will be converted into $15.00 per share in cash and AT&T will become the
sole stockholder of the Company.

Acquisition of Management Consulting and Research, Inc.

Effective September 2, 1999, the Company acquired all of the outstanding stock
of Management Consulting and Research, Inc. (MCR). The net purchase price of
approximately $23 million was paid with 2 million shares of GRCI's common stock
valued at approximately $16 million, and the remainder of approximately $7
million in net cash was financed through the new credit agreement. The resulting
$20.8 million in goodwill is to be amortized over 30 years. The operating
results of MCR are included in the consolidated operating results since the date
of acquisition.

Results of Operations - Three Months Ended December 31, 1999 and 1998

Revenues

Revenues for the second quarter of fiscal 2000 increased 30% to $50.7 million,
from $39.1 million for the same quarter in fiscal 1999. The recently acquired
business of MCR added $7.9 million of revenue in the current quarter. Exclusive
of MCR revenue, the revenue increase in the second quarter of fiscal 2000 over
the year earlier period would have been 10%. Revenues from the Company's largest
contract, the GCSS program, reached $10.3 million in the most recent quarter, an
increase of $3.5 million over the same period in fiscal 1999. The remaining
revenue growth was derived from a broad base of other U.S. government contracts
and subcontracts.

The following table sets forth for the periods indicated the percentage that
certain items of income and expense bear to revenues.

Cost of Revenues

Cost of revenues for the second quarter of fiscal 2000 increased 26% to $41.5
million, or 81.8% of revenues, from $32.9 million, or 84.2% of revenues, for the
same quarter in fiscal 1999. The cost of revenue increase of $8.6 million is
primarily a result of the increase in revenues. The decrease of cost of revenues
as a percentage of revenues is due to efficiencies achieved in labor
productivity, program management, and control of other operating costs.

Indirect Expenses and Operating Income

Indirect expenses consist of selling, general and administrative, research and
development, and other costs. Indirect expenses for the second quarter of fiscal
2000 increased $2.3 million to $6.2 million, from $3.9 million for the second
quarter of fiscal 1999. Indirect expenses as a percentage of revenue were 12.2%
for second quarter 2000, compared to 10.1% for second quarter 1999. Indirect
expenses in the quarter included $800 thousand of non-recurring costs relating
to settlement of a proxy dispute resolved within the quarter. Exclusive of these
proxy-related expenses, indirect expenses would have been $5.4 million, or 10.6%
of revenues.

Operating income for the second quarter of fiscal 2000 increased 36% to $3.0
million, or 6.0% of revenues, from $2.2 million, or 5.7% of revenues, for the
same quarter of fiscal 1999. Without the proxy-related expenses, operating
margins would have been 7.5% of revenues. The increase in operating margins is
related to the efficiencies achieved in the cost of revenues described above.

Net Interest Expense

Net interest expense for the second quarter of fiscal 2000 decreased 19% to $275
thousand, from $340 thousand for the second quarter of fiscal 1999. This
decrease of $65 thousand reflects a reduction in debt levels stemming from
positive operating cash flows in the past year, partially offset by the effect
of borrowings to complete the MCR acquisition.

Income Taxes

The net tax provision recognized in the second quarter of fiscal 2000 was 40.2%
of pretax income. In the second quarter of 1999, the Company recorded a tax
benefit of $1.2 million related to the recognition of the benefit of tax net
operating losses from prior years.

Results of Operations - Six Months Ended December 31, 1999 and 1998

Revenues

Revenues for the first half of fiscal 2000 increased 27% to $96.5 million, from
$75.8 million for the first half of fiscal 1999. The acquired business of MCR
added $10.4 million of revenue in the four months since its acquisition in
September. Revenues from the Company's largest contract, the GCSS program,
reached $19.4 million in the first half of fiscal 2000, an increase of $7.4
million over the first half of fiscal 1999. The remaining revenue growth was
derived from a broad base of other U.S. government contracts and subcontracts.

Cost of Revenues

Cost of revenues for the first half of fiscal 2000 increased 23% to $78.5
million, or 81.3% of revenues, from $63.9 million, or 84.3% of revenues, for the
same period of fiscal 1999. The cost of revenue increase of $14.6 million is
primarily a result of the increase in revenues. The decrease in cost of revenues
as a percent of revenues is partially due to two non-recurring items of revenue
of approximately $920 thousand, with no associated costs. These items related to
favorable settlement of government cost audits ($700 thousand) and settlement of
an old claim for a contract overrun ($220 thousand). The remainder of the
decrease of cost of revenues as a percentage of revenues is due to efficiencies
achieved in labor productivity, program management, and control of other
operating costs.

Indirect Expenses and Operating Income

Indirect expenses consist of selling, general and administrative, research and
development, and other costs. Indirect expenses for the first half of fiscal
2000 increased $3.2 million to $10.8 million from $7.6 million for the first
half of fiscal 1999. Indirect expenses as a percentage of revenue were 11.2% for
first half of fiscal 2000, compared to 10.0% for first half of fiscal 1999.
Indirect expenses in the first half included $900 thousand of non-recurring
costs relating to settlement of a proxy dispute resolved within the quarter.
Exclusive of these proxy-related expenses, indirect expenses would have been
$10.0 million, or 10.4% of revenues.

Operating income for the first half of fiscal 2000 increased 66% to $7.2
million, or 7.5% of revenues, from $4.3 million, or 5.7% of revenues, for the
first half of fiscal 1999. The one-time revenue items of $920 thousand discussed
above are offset by the $900 thousand of proxy-related expenses in the first
half. The increase in operating margins related to the reduction in cost of
revenues due to operating efficiencies noted above.

Net Interest Expense

Net interest expense for the first half of fiscal 2000 decreased 27% to $505
thousand, from $692 thousand for the first half of fiscal 1999. This decrease of
$187 thousand reflects a reduction in debt levels stemming from positive
operating cash flows in the past year, partially offset by the effect of
borrowings to complete the MCR acquisition.


13

Income Taxes

The net tax provision recognized in the first half of fiscal 2000 was 40.2% of
pretax income. In the first half of fiscal 1999, the Company recorded a tax
benefit of $2.5 million related to the recognition of the benefit of tax net
operating losses from prior years.

Liquidity and Capital Resources

Net cash provided by operations amounted to $4.3 million during the first half
of fiscal 2000, compared to cash used in operations of $1.4 million for the
first half of fiscal 1999. The increased operating cash flow was the result of
higher earnings before income taxes. Also, no significant income taxes were paid
in either period because of the offset available from tax net operating loss
carryforwards. Cash flows used in investing activities during the first half of
fiscal 2000 were $8.6 million, compared to $1.0 million used in the first half
of fiscal 1999, due to $7.1 million of cash used in the purchase of MCR, Inc.
The net cash requirements in the first half of fiscal 2000 were met through
additional borrowings under the Company's bank line of credit.

The Company believes that its cash flow from operations, particularly with the
availability of tax operating loss carryforwards to offset future tax
liabilities, and its line of credit are sufficient to meet its financing needs.

Subsequent Event

On February 14, 2000, the Company executed a definitive merger agreement with
AT&T Corp. under which AT&T will commence a cash tender offer to acquire all of
the outstanding shares of the Company for $15.00 per share. The Company's Board
has received a fairness opinion on AT&T's offer. The Boards of Directors of both
companies have unanimously approved the merger agreement. The tender offer will
commence within seven business days and is expected to conclude within
approximately two months.

The tender offer is subject to a majority of the Company's common stock on a
fully diluted basis being validly tendered and not withdrawn, the expiration of
the Hart-Scott-Rodino waiting period, and other customary conditions. If a
majority of the Company's shares are tendered in response to the offer and the
other conditions to the offer are satisfied or waived, a subsiary of At&T will
be merged into the Company, shares not purchased in the offer will be converted
into $15.00 per share in cash and AT&T will become the sole stockholder of the
Company.
