                  ---------------------------------------

The following documents, which have been or will be filed with the Commission,
are hereby incorporated by reference:

1.  The Registrant's Annual Report on Form 10-K for the fiscal year ended June
30, 1999;

2.  The description of the Registrant's common stock, and any rights relating
thereto, contained in the Registrant's registration statement(s) relating to
the common stock filed with the Commission under the Securities Exchange Act
of 1934, including any amendment or report filed for the purpose of updating
the description;

3.  All documents filed by the Registrant pursuant to Sections 13(a) and 15(d)
of the Securities Exchange Act of 1934 since June 30, 1999; and

4.  All documents hereafter filed by the Registrant pursuant to Sections 13(a),

filing of a post-effective amendment which indicates that all securities

Item 4.           Description of Securities.
                  -------------------------

Not applicable.


Item 5.           Interests of Counsel.
                  --------------------

     The validity of the shares of common stock offered hereby has been
passed upon for the Registrant by Thomas E. McCabe, Esq., Senior Vice
President, General Counsel and Secretary of the Registrant.  As of
September 3, 1999, Mr. McCabe owns 18,190.67 units of the GRC International
Stock Fund in the Registrant's Deferred Income Plan, 0.8809 shares in
the Company's Employee Stock Purchase Plan, and options to purchase
83,400 additional shares.


Item 6.           Indemnification of Directors and Officers.
                  -----------------------------------------

     The Registrant's Bylaws provide for the indemnification of directors and
officers to the fullest extent permitted by Delaware law except that a director
or officer may be indemnified for costs of a proceeding that he has initiated
only if the proceeding was authorized by the Board of Directors.  Additionally,
the Registrant has adopted an Indemnification Agreement to be used as the basis
for specific agreements between the Registrant and individual directors and
officers to ensure contractual assurance that the protections conferred by the
Registrant's Bylaws will be available to the indemnitee to the extent required,
permitted or not prohibited by law.  The Bylaws and the Indemnification
Agreement further provide for a mechanism whereby indemnification claims shall
be paid within thirty (30) days after such claim has been received unless
independent legal counsel has determined that indemnification of such person
would be prohibited, in whole or in part, under applicable law, or that a claim
for expenses shall not be paid, in whole or in part, on the grounds that it is
unreasonably high.  Such determination shall be conclusively binding on the
Registrant and on the claimant.  If no such determination is made by indepen-
dent legal counsel and the claim is not paid within thirty (30) days, the
claimant has the right to pursue its claim against the Registrant in the
courts.  Under Delaware law, a director or officer may not be indemnified
unless a determination is made that he was acting in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best
interests of the Registrant and, in the case of a criminal proceeding, he
reasonably believed to be lawful.

     The directors and officers of the Registrant are insured under liability
insurance policies purchased by the Registrant. However, the Registrant shall
not be required either to obtain or maintain said policy or policies of
insurance if it is not reasonably available or if, in the reasonable business
judgment of the then directors of the Registrant, either (i) the premium cost
for such insurance is substantially disproportionate to the amount of coverage;
or (ii) the coverage provided by such insurance is so limited by exclusions
that there is insufficient benefit from such insurance.


Item 7.           Exemption from Registration Claimed.
                  -----------------------------------

                  Not applicable.

Item 9.           Undertakings.
                  ------------

(a)  The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being
      made, a post-effective amendment to this registration statement:

              (i) To include any prospectus required by section 10(a)(3) of the
          Securities Act of 1933;

              (ii) To reflect in the prospectus any facts or events arising
          after the effective date of the registration statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the registration statement.  Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus  filed with the Commission  pursuant to Rule 424(b)
          if, in the aggregate, the changes in volume and price represent no
          more than a 20% change in the maximum aggregate offering price set
          forth in the "Calculation of Registration Fee" table in the effective
          registration statement.

               (iii) To include any material information with respect to the
          plan of distribution not previously disclosed in the registration
          statement or any material change to such information in the
          registration statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed with or furnished to the Commission by the registrant
pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in the registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering;

(b)  The undersigned registrant hereby undertakes that, for purposes of
determining liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

(c)  Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

September 28, 1999


GRC International, Inc.
1900 Gallows Road
Vienna, Virginia  22182


Gentlemen:

I have assisted GRC International, Inc. ("Registrant") in connection with the
filing with the Securities and Exchange Commission ("Commission") of a
Registration Statement on Form S-8 under the Securities Act of 1933 relating
to the offer and sale of up to 736,271 shares of the Registrant's common stock
pursuant to its Directors Fee Replacement Plan and its 1998 Option Plan (the
"Plans").  I have examined the Registrant's charter and bylaws, the Plans and
resolutions authorizing the Plans, and such other documents as I have deemed
necessary to render the opinion expressed herein.

Based on the foregoing, it is my opinion that the shares of common stock that
may be originally issued by the Company pursuant to the Plans, when sold in
accordance with the provisions of the Plans and the resolutions authorizing
the Plans for a price per share not less than the par value thereof, will be
validly issued, fully paid and non-assessable.

I consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to me under the caption "Interests of Counsel"
in the Registration Statement. I do not thereby admit that I am an "expert" as
that term is used in the Securities Act of 1933 and the Rules and Regulations
thereunder.

Sincerely,

/s/ Thomas E. McCabe
Thomas E. McCabe
Senior Vice President,
  General Counsel and Secretary

PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.           Incorporation of Documents by Reference.
                  ---------------------------------------

The following documents, which have been or will be filed with the Commission,
are hereby incorporated by reference:

1.  The Registrant's Annual Report on Form 10-K for the fiscal year ended June
30, 1999;

2.  The description of the Registrant's common stock, and any rights relating
thereto, contained in the Registrant's registration statement(s) relating to
the common stock filed with the Commission under the Securities Exchange Act
of 1934, including any amendment or report filed for the purpose of updating
the description;

3.  All documents filed by the Registrant pursuant to Sections 13(a) and 15(d)
of the Securities Exchange Act of 1934 since June 30, 1999; and

4.  All documents hereafter filed by the Registrant pursuant to Sections 13(a),

filing of a post-effective amendment which indicates that all securities

     Any statement contained in a document incorporated or deemed to be

other subsequently filed document which also is or is deemed to be incorporated
in this Registration Statement by reference modifies or supersedes such
statement.  Any statement so modified shall not be deemed in its unmodified
form, and any statement so superseded shall not be deemed, to constitute a

Item 4.           Description of Securities.
                  -------------------------

Not applicable.

Item 5.           Interests of Counsel.
                  --------------------

     The validity of the shares of common stock offered hereby has been
passed upon for the Registrant by Thomas E. McCabe, Esq., Senior Vice
President, General Counsel and Secretary of the Registrant.  As of
September 3, 1999, Mr. McCabe owns 18,190.67 units of the GRC International
Stock Fund in the Registrant's Deferred Income Plan, 0.8809 shares in
the Company's Employee Stock Purchase Plan, and options to purchase
83,400 additional shares.

Item 6.           Indemnification of Directors and Officers.
                  -----------------------------------------

     The Registrant's Bylaws provide for the indemnification of directors and
officers to the fullest extent permitted by Delaware law except that a director
or officer may be indemnified for costs of a proceeding that he has initiated
only if the proceeding was authorized by the Board of Directors.  Additionally,
the Registrant has adopted an Indemnification Agreement to be used as the basis
for specific agreements between the Registrant and individual directors and
officers to ensure contractual assurance that the protections conferred by the
Registrant's Bylaws will be available to the indemnitee to the extent required,
permitted or not prohibited by law.  The Bylaws and the Indemnification
Agreement further provide for a mechanism whereby indemnification claims shall
be paid within thirty (30) days after such claim has been received unless
independent legal counsel has determined that indemnification of such person
would be prohibited, in whole or in part, under applicable law, or that a claim
for expenses shall not be paid, in whole or in part, on the grounds that it is
unreasonably high.  Such determination shall be conclusively binding on the
Registrant and on the claimant.  If no such determination is made by indepen-
dent legal counsel and the claim is not paid within thirty (30) days, the
claimant has the right to pursue its claim against the Registrant in the
courts.  Under Delaware law, a director or officer may not be indemnified
unless a determination is made that he was acting in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best
interests of the Registrant and, in the case of a criminal proceeding, he
reasonably believed to be lawful.

     The directors and officers of the Registrant are insured under liability
insurance policies purchased by the Registrant. However, the Registrant shall
not be required either to obtain or maintain said policy or policies of
insurance if it is not reasonably available or if, in the reasonable business
judgment of the then directors of the Registrant, either (i) the premium cost
for such insurance is substantially disproportionate to the amount of coverage;
or (ii) the coverage provided by such insurance is so limited by exclusions
that there is insufficient benefit from such insurance.

Item 7.           Exemption from Registration Claimed.
                  -----------------------------------

                  Not applicable.

Item 8.           Exhibits  (exhibit  numbers  correspond to Exhibit Table,

Item 9.           Undertakings.
                  ------------

(a)  The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being
      made, a post-effective amendment to this registration statement:

              (i) To include any prospectus required by section 10(a)(3) of the
          Securities Act of 1933;

              (ii) To reflect in the prospectus any facts or events arising
          after the effective date of the registration statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the registration statement.  Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus  filed with the Commission  pursuant to Rule 424(b)
          if, in the aggregate, the changes in volume and price represent no
          more than a 20% change in the maximum aggregate offering price set
          forth in the "Calculation of Registration Fee" table in the effective
          registration statement.

               (iii) To include any material information with respect to the
          plan of distribution not previously disclosed in the registration
          statement or any material change to such information in the
          registration statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed with or furnished to the Commission by the registrant
pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in the registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering;

(b)  The undersigned registrant hereby undertakes that, for purposes of
determining liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

(c)  Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

GRC International, Inc.
1900 Gallows Road
Vienna, Virginia  22182

Gentlemen:

I have assisted GRC International, Inc. ("Registrant") in connection with the
filing with the Securities and Exchange Commission ("Commission") of a
Registration Statement on Form S-8 under the Securities Act of 1933 relating
to the offer and sale of up to 736,271 shares of the Registrant's common stock
pursuant to its Directors Fee Replacement Plan and its 1998 Option Plan (the
"Plans").  I have examined the Registrant's charter and bylaws, the Plans and
resolutions authorizing the Plans, and such other documents as I have deemed
necessary to render the opinion expressed herein.

Based on the foregoing, it is my opinion that the shares of common stock that
may be originally issued by the Company pursuant to the Plans, when sold in
accordance with the provisions of the Plans and the resolutions authorizing
the Plans for a price per share not less than the par value thereof, will be
validly issued, fully paid and non-assessable.

I consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to me under the caption "Interests of Counsel"
in the Registration Statement. I do not thereby admit that I am an "expert" as
that term is used in the Securities Act of 1933 and the Rules and Regulations
thereunder.

Sincerely,

/s/ Thomas E. McCabe
Thomas E. McCabe
Senior Vice President,
  General Counsel and Secretary
