             GRC International Announces Election of Board Members,
                       Settlement of Shareholder Lawsuits

Vienna,  Va., Dec. 13, 1999 - GRC International  (NYSE: GRH) today announced the
election  of Gary L.  Denman,  Neal B.  Freeman,  Richard N. Perle and Joseph R.
Wright Jr. to the company's  board of directors.  The company also announced the
settlement  of  two  previously   reported   lawsuits  filed  by  an  individual
shareholder against the company and seven of its directors.  The board agreed to
the settlement in order to end the distraction and cost of the litigation.

In announcing  the election  results and litigation  settlement,  Board Chairman
Joseph Wright said,  "We are pleased to have Messrs.  Freeman and Perle join the
board and look forward to their  contributions.  We will now turn our  undivided
attention  to  supporting  GRCI's  management  team as they work to  extend  the
excellent performance of the past two years."

Wright,  who continues as chairman of the board,  and Perle were elected by vote
of  shareholders  at the  company's  annual  meeting  held on November  15. As a
condition of the settlement of the two suits, the board reelected GRCI President
and CEO Gary Denman to the board and elected Freeman to his first term. With the
two new members, the board now stands at 10 seats.

New board member Neal Freeman, 59, is chairman and CEO of The Blackwell Corp., a
television  production and distribution  company located in Vienna,  Va. He also
has served as director of COMSAT  Corp.  since 1983 and is vice  chairman of The
Ethics and Public Policy Center and a director of National Review Inc. and Forum
Network Inc.

The board's other new member,  Richard Perle,  57, has been a resident fellow of
the American  Enterprise  Institute's  Commission on Future Defenses since 1987.
From 1981 until 1987,  he was assistant  secretary of Defense for  International
Security Policy of the U.S.  Department of Defense.  He is currently chairman of
Hollinger Digital Inc. and a director of Hollinger International Inc., Jerusalem
Post,  Geobiotics,  American  Interactive  Media Inc.,  AppNet  Systems Inc. and
Morgan Crucible PLC.

In  addition  to the board  elections,  GRCI  shareholders  voted to ratify  the
selection of Deloitte & Touche as the company's  independent  public accountants
and  voted in favor of a  non-binding  shareholder  proposal  to  terminate  the
company's  Shareholder  Rights Plan.  GRCI agreed not to extend the  Shareholder
Rights Plan when it expires on August 31, 2000, as a condition of the settlement
of the suits.

The company also agreed to pay the  plaintiff's  attorney's fees and expenses in
an amount awarded by the court,  but not to exceed  $330,000.  This payment will
bring the total  expenses  incurred by the company during the second quarter for
the proxy contest and for the  litigation  to  approximately  $1 million.  Final
settlement of the suits requires the approval of the Delaware court.
