             GRC International Signs Definitive Agreement To Acquire
                      Management Consulting & Research Inc.

Vienna, Va., August 6, 1999 - GRC International Inc. (NYSE: GRH) today announced
it has signed a  definitive  purchase  agreement  with  Management  Consulting &
Research  Inc.  (MCR) to acquire  all of the  outstanding  shares of MCR and its
subsidiaries.  The  purchase  price of  approximately  $27 million  includes two
million  shares  of GRCI  stock to be held by MCR  Chairman  and CEO Dr.  Gerald
McNichols  (MCR's  principal  shareholder),  with the  remainder  in cash.  GRCI
expects MCR to have  approximately $4 million cash at closing,  bringing the net
cost of the acquisition down to about $23 million. Closing is expected within 30
days pending regulatory and MCR shareholder approval.

become a strong competitor in its markets with current revenues of approximately
$30  million.  GRC  International  expects  to  retain  MCR's  management  team,
employees and facilities and operate MCR as a wholly owned subsidiary from MCR's
headquarters in McLean, Va. Dr. McNichols plans to continue in a transition role
with GRCI and will be nominated to serve as a director of GRC International.

GRC  International  President and CEO Gary Denman said, "I am extremely  pleased
with the expanded capabilities this acquisition provides GRC International.  MCR
is known  for the  quality  of its  services  and  employees,  and its  focus on
profitability.  It has  been  honored  as an  'Inc.  500'  company,  'Washington
Technology Fast 50' company,  'National  Technology 500' company,  and 'Virginia
Fantastic 50' company.  MCR brings a set of  complementary  and valuable  skills
that we can apply to our current  clients,  and provides  direct access to a new
set of clients for GRCI's technical services.

"As I have stated before," continued Denman,"  acquisitions are very much a part
of our growth strategy.  We have been very selective in this acquisition program
to ensure that it will be compatible with our existing operations,  and one that
we expect to be accretive to earnings and a positive  contributor to shareholder
value.  The  acquisition  of MCR is an excellent  start and keeps us on track to
achieve  our growth  objectives.  I look  forward to  working  closely  with Dr.
McNichols  and the rest of his  management  team as we  continue  to execute our
plans."
