EXHIBIT 10.10

                       UNITED SHIPPING & TECHNOLOGY, INC.
                        (FORMERLY KNOWN AS U-SHIP, INC.)

                         1996 DIRECTOR STOCK OPTION PLAN

         1. Purpose of the Plan. The purpose of this 1996 Director Stock Option
Plan, adopted by the Board on January 29, 1996, and amended on May 3, 1999, (the
"Plan") is to attract and retain the best available individuals to serve as
Directors of United Shipping & Technology, Inc. (formerly known as U-Ship,
Inc.), a Utah corporation (the "Company"), to provide additional incentive to
the Outside Directors of the Company to serve as Directors, and to encourage
their continued service on the Board.

                  The Company intends that the options granted hereunder shall
not constitute incentive stock options within the meaning of Section 422 of the
Internal Revenue Code of 1986. The Plan is intended to comply with the
requirements of Rule 16b-3 under the Exchange Act.

         2. Definitions. As used herein, the following definitions shall apply:

                  (a) "Board" shall mean the Board of Directors of the Company.

                  (b) "Common Stock" shall mean the Common Stock, $.004 par
         value per share, of the Company.

                  (c) "Company" shall mean United Shipping & Technology, Inc.
         and any subsidiary of the Company.

         Service as a Director shall not be considered interrupted in the case
         of sick leave, military leave, or any other leave of absence approved
         by the Board or Committee.

                  (f) "Director" shall mean a member of the Board.

         Directors, employed by the Company or any Parent or Subsidiary of the
         Company. The payment of fees to a Director shall not be sufficient in
         and of itself to constitute "employment" by the Company.

         1934, as amended.

                  (i) "Option" shall mean a stock option granted pursuant to the

of the Plan, the maximum aggregate number of shares which may be optioned and
sold under the Plan is 210,000 shares of Common Stock. The shares may be
authorized, but unissued, or reacquired Common Stock.

                  If an Option expires or becomes unexercisable for any reason
without having been exercised in full, the unexercised Shares which were subject
thereto shall, unless the Plan has been terminated, become available for future
grant under the Plan. If Shares which were acquired upon exercise of an Option
are subsequently repurchased by the Company, such Shares shall not become
available for future grant under the Plan.

         4. Automatic Grant of Options. All grants of Options hereunder shall be
automatic and non-discretionary and shall be made strictly in accordance with
the following provisions:

                  (a) No person shall have any discretion to select which
         Outside Directors shall be granted Options or to determine the number
         of Shares to be covered by Options granted to Outside Directors.

                  (b) Each Outside Director, including persons who are Outside
         Directors on the date of adoption of the Plan, shall be automatically
         granted an option to purchase 15,000 Shares (the "First Option") upon
         the later to occur of (i) the effective date of the Plan, as determined
         in accordance with Section 8 hereof, or (ii) the date on which such
         person first becomes an Outside Director, whether through election by
         the shareholders of the Company or appointment by the Board to fill a
         vacancy.

                  (c) After the First Option has been granted to an Outside
         Director, such Outside Director shall thereafter be automatically
         granted an Option to purchase 15,000 shares on the

                                       2
<PAGE>

         first and each successive anniversary of the grant of the First Option;
         provided, however, that in no event shall an Outside Director be
         granted options to purchase in the aggregate more than 45,000 shares
         pursuant to the Plan.

                  (d) Notwithstanding the provisions of Sections 4(b) and (c)
         hereof, in the event that a grant would cause the number of Shares
         subject to outstanding Options to Outside Directors plus Shares
         previously purchased upon exercise of Options by Outside Directors to
         exceed 210,000 Shares, then each such automatic grant shall be for that
         number of Shares determined by dividing the total number of Shares
         remaining available for grant by the number of Outside Directors on the
         automatic grant date. Any further grants shall then be deferred until
         such time, if any, as additional Shares become available for grant
         under the Plan through action of the shareholders to increase the
         number of Shares which may be issued under the Plan or through
         cancellation or expiration of Options previously granted hereunder.

         5. Option Terms and Conditions. The terms and conditions of an Option
granted hereunder shall be as follows:

                  (a) the term of each Option shall be five (5) years, subject
         to Sections 12 and 13 hereof.

                  (b) the First Option shall become exercisable in full
         beginning on the later of (i) the first anniversary of the grant of the
         Option or (ii) twelve (12) months after the date on which the Plan is
         first approved by the shareholders of the Company in accordance with
         Rule 16b-3 under the Exchange Act and each subsequent Option shall
         become exercisable in full beginning on the first anniversary of the
         grant of such Option, provided in each case that the Outside Director
         shall have maintained Continuous Service as an Outside Director
         throughout such 12-month period.

                  (c) the Option shall be exercisable only while the Outside
         Director serves as an Outside Director of the Company, and for a period
         of six (6) months after ceasing to be an Outside Director pursuant to
         Section 10(b) hereof.

                  (d) the exercise price per Share shall be 100% of the fair
         market value per Share on the date of grant of the Option, as
         determined in accordance with Section 9(a) hereof.

                  (e) the effectiveness of any Options granted hereunder is
         conditioned upon shareholder approval of the Plan in accordance with
         Rule 16b-3 under the Exchange Act.

         6. Administration of and Grants of Options under the Plan.

                  (a) Administration. Except as otherwise required herein, the
         Plan shall be administered by the Board or a Committee.

                                       3
<PAGE>

                  (b) Powers of the Board or Committee. Subject to the
         provisions and restrictions of the Plan, the Board or Committee shall
         have the authority, in its discretion: (i) to determine, upon review of
         relevant information and in accordance with Section 9(a) hereof, the
         fair market value of the Common Stock; (ii) to interpret the Plan;
         (iii) to prescribe, amend and rescind rules and regulations relating to
         the Plan; (iv) to authorize any person to execute on behalf of the
         Company any instrument required to effectuate the grant of an Option
         hereunder; and (v) to make all other determinations deemed necessary or
         advisable for the administration of the Plan. On a case by case basis,
         the Board or Committee may, in their sole discretion, accelerate the
         Schedule of the time or times when an Option granted under the Plan may
         be exercised.

                  (c) Effect of Board or Committee Decision. All decisions,
         determinations and interpretations of the Board or Committee shall be
         final and binding on all Optionees and any other holders of any Options
         granted under the Plan.

                  (d) Suspension or Termination of Option. If the Board or
         Committee reasonably believes that an Optionee has committed an act of
         misconduct, it may suspend the Optionee's right to exercise any Option
         pending a determination by the Board or Committee (excluding the
         Outside Director accused of such misconduct). If the Board or Committee
         (excluding the Outside Director accused of such misconduct) determines
         that an Optionee has committed an act of embezzlement, fraud,
         dishonesty, nonpayment of an obligation owed to the Company, breach of
         fiduciary duty or deliberate disregard of the Company's rules resulting
         in loss, damage or injury to the Company, or if an Optionee makes an
         unauthorized disclosure of any Company trade secret or confidential
         information, engages in any conduct constituting unfair competition
         with respect to the Company, or induces any party to breach a contract
         with the Company, neither the Optionee nor the Optionee's estate shall
         be entitled to exercise any Option whatsoever. In making such
         determination, the Board or Committee (excluding the Outside Director
         accused of such misconduct) shall act fairly and shall give the
         Optionee an opportunity to appear and present evidence on the
         Optionee's behalf at a hearing before the Board or Committee.

                  (e) Date of Grant of Options. The date of grant of an Option
         shall, for all purposes, be the date determined in accordance with
         Section 4 hereof, notwithstanding the fact that an Optionee may not
         have entered into an option agreement with the Company on such date.
         Notice of the grant of an Option shall be given to the Optionee within
         a reasonable time after the date of such grant.

         7. Eligibility. Options may be granted only to Outside Directors. All
options shall be automatically granted in accordance with the terms set forth in
Section 4 hereof. The Plan shall not confer upon any Optionee any right with
respect to continuation of service as a Director or nomination to serve as a
Director, nor shall it interfere in any way with any rights which a Director or
the Company may have to terminate such Director's directorship at any time.

                                       4

         8. Term of Plan. The effective date of this Plan is January 29, 1996,
the date upon which it was adopted by the Board. The Plan shall continue in
effect for a term of ten (10) years unless terminated sooner under Section 13
hereof.

         9. Fair Market Value and Form of Consideration.

                  (a) Fair Market Value. The fair market value per share shall
         be determined as follows:

                           (i) if the Common Stock is listed on a national
                  securities exchange or admitted to unlisted trading privileges
                  on such exchange, the fair market value on any given day shall
                  be the closing sale price for the Common Stock on such day, as
                  reported in the Wall Street Journal or other newspaper of
                  general circulation;

                           (ii) if the Common Stock is not listed on a national
                  securities exchange, the fair market value on any given day
                  shall be the closing sale price for the Common Stock on the
                  NASDAQ National Market System on such day, as reported in the
                  Wall Street Journal or other newspaper of general circulation;

                           (iii) if the Common Stock is not listed on a national
                  securities exchange, is not admitted to unlisted trading
                  privileges on any such exchange, and is not eligible for
                  inclusion on the NASDAQ National Market System, the fair
                  market value on any given day shall be the average of the
                  closing representative bid and asked prices on such day, as
                  reported on the NASDAQ System, and if not reported on such
                  system, then as reported by the National Quotation Bureau,
                  Inc. or such other publicly available compilation of the bid
                  and asked prices of the Common Stock in any over- the-counter
                  market on which the Common Stock is traded; or

                           (iv) if there exists no public trading market for the
                  Common Stock, the fair market value on any given day shall be
                  an amount determined by the Board or Committee in such manner
                  as it may reasonably determine in its discretion, provided
                  that such amount shall not be less than the book value per
                  share as reasonably determined by the Board or Committee as of
                  the date of determination nor less than the par value of the
                  Stock.

                  (b) Form of Consideration. The consideration to be paid for
         the Shares to be issued upon exercise of an Option shall consist
         entirely of cash or such other form of consideration as the Board or
         Committee may determine, in its sole discretion, to be appropriate for
         payment, including but not limited to other shares of Common Stock
         having a fair market value on the date of surrender equal to the
         aggregate exercise price of the Shares as to which the Option is
         exercised, or any combination of such methods of payment.

                                       5

         10. Exercise of Option.

                  (a) Procedure for Exercise; Rights as a Shareholder. Any
         Option granted hereunder shall be exercisable at such times as are set
         forth in Section 5 hereof. An Option may not be exercised for a
         fraction of a Share.

                  An Option shall be deemed to be exercised when written notice
         of such exercise has been given to the Company in accordance with the
         terms of the Option by the person entitled to exercise the Option and
         full payment for the Shares with respect to which the Option is
         exercised has been received by the Company. Full payment may consist of
         any consideration and method of payment allowable under Section 9(b)
         hereof. Until the issuance (as evidenced by the appropriate entry on
         the books of the Company or of a duly authorized transfer agent of the
         Company) of the stock certificate evidencing such Shares, no right to
         vote or receive dividends or any other rights as a shareholder shall
         exist with respect to the Optioned Stock, notwithstanding the exercise
         of the Option. A share certificate for the number of Shares so acquired
         shall be issued to the Optionee as soon as practicable after exercise
         of the Option. No adjustment will be made for a dividend or other right
         for which the record date is prior to the date the stock certificate is
         issued, except as provided in Section 12 hereof.

                  Exercise of an Option in any manner shall result in a decrease
         in the number of Shares which thereafter may be available, both for
         purposes of the Plan and for sale under the Option, by the number of
         Shares as to which the Option was exercised.

                  (b) Termination of Status as a Director. If an Optionee ceases
         to serve as a Director, the Optionee may, but only within twelve (12)
         months after the date the Optionee ceases to be an Outside Director of
         the Company, exercise his or her Option to the extent the Optionee was
         entitled to exercise it at the date of such termination. To the extent
         that the Optionee was not entitled to exercise an Option at the date of
         such termination, or if the Optionee does not exercise such Option
         within the time specified herein, the Option shall terminate.

                  (c) Death of Optionee. In the event of the death of an
         Optionee occurring:

                           (i) during the term of the Option, and provided that
                  the Optionee was at the time of death a Director of the
                  Company and had been in Continuous Service as a Director since
                  the date of grant of the Option, the Option may be exercised,
                  at any time within twelve (12) months following the date of
                  death, by the Optionee's estate or by a person who acquired
                  the right to exercise the Option by bequest or inheritance,
                  but only to the extent of the right to exercise that would
                  have accrued had the Optionee continued living and remained in
                  Continuous Service a Director for twelve (12) months after the
                  date of death; or

                           (ii) within thirty (30) days after the termination of
                  Continuous Service as a Director, the Option may be exercised,
                  at any time within six (6) months following

                                       6
<PAGE>

                  the date of death, by the Optionee's estate or by a person who
                  acquired the right to exercise the Option by bequest or
                  inheritance, but only to the extent of the right to exercise
                  that had accrued at the date of termination of Continuous
                  Service as a Director.

         11. Non-Transferability of Options. The Option may not be sold,
pledged, assigned, hypothecated, transferred, or disposed of in any manner other
than by will or by the laws of descent or distribution and may be exercised,
during the lifetime of the Optionee, only by the Optionee.

         12. Adjustments Upon Changes in Capitalization or Merger. The number of
Shares of Common Stock covered by each outstanding Option, and the number of
Shares of Common Stock which have been authorized for issuance under the Plan
but as to which Options have not yet been granted or which have been returned to
the Plan upon cancellation or expiration of an Option, as well as the price per
Share of Common Stock covered by each such outstanding Option, shall be
proportionately adjusted for any increase or decrease in the number of issued
and outstanding Shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of issued shares of
Common Stock effected without receipt of consideration by the Company; provided,
however, that conversion of any convertible securities of the Company shall not
be deemed to have been "effected without receipt of consideration." Such
adjustment shall be made by the Board, whose determination in that respect shall
be final, binding and conclusive. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, or options or rights to purchase
shares of stock of any class shall affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of shares of Common Stock
subject to an Option.

                  In the event of the proposed dissolution or liquidation of the
Company, each Option will terminate immediately prior to the consummation of
such proposed action, unless otherwise provided by the Board. The Board may, in
the exercise of its sole discretion in such instances, declare that any Option
shall terminate as of a date fixed by the Board and give each Optionee the right
to exercise his or her Option as to all or any part of the Optioned Stock,
including Shares as to which the Option would not otherwise be exercisable. In
the event of a proposed sale of all or substantially all of the assets of the
Company, or the merger of the Company with or into another corporation, the
Option shall be assumed or an equivalent option shall be substituted by such
successor corporation or a parent or subsidiary of such successor corporation,
unless the Board determines, in the exercise of its sole discretion and in lieu
of such assumption or substitution, that the Optionee shall have the right to
exercise the Option as to all of the Optioned Stock, including Shares as to
which the Option would not otherwise be exercisable. If the Board makes an
Option fully exercisable in lieu of assumption or substitution in the event of a
merger or sale of assets, the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of ten (10) days from the date of such
notice, and the Option will terminate upon the expiration of such period.

                                       7

         13. Amendment, Termination and Approval of the Plan. The Board may at
any time amend or terminate the Plan, except that the Board shall not amend the
Plan more than once every six (6) months with respect to the provisions of the
Plan relating to the amount, price, and timing of grants, other than to comply
with changes in the Internal Revenue Code of 1986, the Employee Retirement
Income Security Act of 1974, as amended, or the regulations thereunder. No
Option may be granted after the Plan is terminated. The foregoing provisions of
this Section notwithstanding, no amendment or termination shall, without the
consent of the holder of an Option, alter or impair any rights or obligations
under any Option theretofore granted under the Plan except as is permitted
pursuant to Section 12 of the Plan.

                  If any amendment to the Plan requires approval by the
shareholders of the Company for continued applicability of Rule 16b-3 under the
Exchange Act, or for initial or continued listing of the Common Stock or other
securities of the Company upon any stock exchange, then such amendment shall be
approved by the holders of a majority of the Company's outstanding capital stock
entitled to vote.

         14. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, state securities laws, and the requirements of the NASD or any stock
exchange upon which the Shares may then be listed, and shall be further subject
to the approval of counsel for the Company with respect to such compliance.

                  As a condition to the exercise of an Option, the Company may
require the person exercising such Option to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares, if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law. Such Shares may also be issued
with appropriate legends on stock certificates representing such Shares, and the
Company may place stop transfer orders with respect to such Shares.

                  Inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority shall not have been
obtained.

         15. Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

         16. Option Agreement. Options shall be evidenced by written option
agreements as the Board or Committee shall approve.

         17. Information to Optionees. The Company shall provide to each
Optionee, during the period for which such Optionee has one or more Options
outstanding, copies of all annual reports and other information which are
provided to all shareholders of the Company.

                          AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER, dated as of February 14, 2000 (the
"Agreement"), among GRC INTERNATIONAL, INC., a Delaware corporation (the
"Company"), AT&T CORP., a New York corporation ("Parent"), and LMN CORPORATION,
a Delaware corporation and an indirect wholly owned subsidiary of Parent
("Purchaser").

                              W I T N E S S E T H:
                              - - - - - - - - - -

     WHEREAS, the respective Boards of Directors of the Company and Purchaser
have each determined that it is in the best interests of their respective
stockholders for Parent to acquire the Company upon the terms and subject to the
conditions set forth herein; and

     WHEREAS, in furtherance thereof, it is proposed that Purchaser will make a
cash tender offer (as it may be amended from time to time as permitted under
this Agreement, the "Offer") to acquire all of the issued and outstanding shares
(the "Shares") of the common stock, $.10 par value, of the Company (the "Company
Common Stock") at a purchase price of fifteen dollars ($15) per Share (such
price or such higher price as may be paid in the Offer, the "Per Share Amount"),
net to the seller in cash; and

     WHEREAS, the respective Boards of Directors of the Company, Purchaser and
Parent have each approved this Agreement and the merger (the "Merger") of
Purchaser with and into the Company following the consummation of the Offer and
upon the terms and subject to the conditions set forth herein; and

     WHEREAS, the Board of Directors of the Company (the "Board of Directors")
has determined that the consideration to be paid for each Share in the Offer and
the Merger is fair to the holders of such Shares and to recommend that the
holders of such Shares accept the Offer and approve this Agreement and the
transactions contemplated hereby; and

     WHEREAS, the Board of Directors has approved the terms of the Stockholders
Agreements attached hereto as Exhibits A and B (the "Stockholders Agreements")
to be entered into among Parent, Purchaser and certain holders of Shares (the
"Stockholders") simultaneously herewith, pursuant to which such Stockholders
have, among other things, agreed to tender their Shares pursuant to the Offer.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby, the
Company, Parent and Purchaser hereby agree as follows:

<PAGE>

                                   Article I.

                                THE TENDER OFFER

     SECTION 1.1. The Offer.

     (a) Provided that this Agreement shall not have been terminated in
accordance with Section 8.1 hereof and none of the events set forth in Annex I
hereto shall have occurred and be existing, Purchaser shall commence (within the
meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) the Offer as promptly as reasonably practicable, but in no
event later than seven business days following the public announcement by Parent
and the Company of the execution of this Agreement. The obligation of Purchaser
to accept for payment and pay for any Shares tendered pursuant to the Offer
shall be subject to the satisfaction of the conditions set forth in Annex I.
Purchaser expressly reserves the right from time to time, subject to Sections
1.1(b) and 1.1(d) hereof, without the consent of the Company to waive any such
condition, to increase the Per Share Amount, or to make any other changes in the
terms and conditions of the Offer. The Per Share Amount shall be net to the
seller in cash, without interest, subject to reduction only for any applicable
withholding taxes or stock transfer taxes payable by the seller. The Company
agrees that no Shares held by the Company or any Subsidiary (as hereinafter
defined) will be tendered pursuant to the Offer.

     (b) Without the prior written consent of the Company, Purchaser shall not
(i) decrease the Per Share Amount or change the form of consideration payable in
the Offer, (ii) seek to purchase less than all outstanding Shares, (iii) amend
or waive satisfaction of the Minimum Condition (as defined in Annex I) or (iv)
impose conditions to the Offer in addition to those set forth in Annex I hereto,
or amend any other term or condition of the Offer in any manner materially
adverse to the holders of Shares. Upon the terms and subject to the conditions
of the Offer and this Agreement, Purchaser will accept for payment and purchase,
as soon as permitted under the terms of the Offer and applicable law (subject to
the first proviso to Section 8.1(c)(i)) (the "Share Purchase Date") all Shares
validly tendered and not withdrawn prior to the expiration of the Offer. On or
prior to the Share Purchase Date, Parent shall provide or cause to be provided
to Purchaser the funds necessary to pay for Shares that Purchaser becomes
obligated to accept for payment, and pay for, pursuant to the Offer. Purchaser
shall not provide for a subsequent offering period in accordance with Rule
14d-11 under the Exchange Act.

     (c) The Offer shall be made by means of an offer to purchase (the "Offer to
Purchase") having only the conditions set forth in Annex I hereto. As soon as
reasonably practicable on the date the Offer is commenced, Purchaser shall file
with the Securities and Exchange Commission (the "SEC") a Tender Offer

                                      -2-

<PAGE>

Statement on Schedule TO (together with all amendments and supplements thereto,
the "Schedule TO") with respect to the Offer that will comply in all material
respects with the provisions of all applicable Federal securities laws, and will
contain (including as an exhibit) or incorporate by reference the Offer to
Purchase and forms of the related letter of transmittal and summary
advertisement (which documents, together with any supplements or amendments
thereto, are referred to collectively herein as the "Offer Documents"). Parent
and Purchaser agree promptly to correct the Schedule TO or the Offer Documents
if and to the extent that it or they shall have become false or misleading in
any material respect (and the Company, with respect to written information
supplied by it specifically for use in the Schedule TO or the Offer Documents,
shall promptly notify Parent of any required corrections of such information and
shall cooperate with Parent and Purchaser with respect to correcting such
information) and to supplement the Schedule TO or the Offer Documents to include
any information that shall become necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading (and the Company shall supplement the information provided by it
specifically for use in the Schedule TO or the Offer Documents to include any
information that shall become necessary in order to make the statements therein
that are based on such provided information, in light of the circumstances under
which they were made, not misleading), and Parent and Purchaser further agree to
take all steps necessary to cause the Schedule TO, as so corrected or
supplemented, to be filed with the SEC and the Offer Documents, as so corrected
or supplemented, to be disseminated to holders of Shares, in each case to the
extent required by applicable Federal securities laws. The Company and its
counsel shall be given a reasonable opportunity to review and comment on the
Schedule TO and any Offer Documents before they are filed with the SEC.

     (d) The Offer to Purchase shall provide (i) for an initial expiration date
of 20 business days (as defined in Rule 14d-1 under the Exchange Act) from and
including the date of commencement of the Offer (the "Initial Expiration Date").
Purchaser shall extend the expiration date of the Offer until 5:00 p.m., Eastern
time, on the earlier of (i) the thirtieth (30th) business day following the
public announcement by Parent and the Company of the execution of this Agreement
(which thirty business days shall for this purpose include the date of such
public announcement) and (ii) if a tender offer (other than the Offer) shall
have been commenced for all or a portion of the Shares, the business day
immediately preceding the initial expiration date of such tender offer (such
earlier date, the "Extended Expiration Date"). Unless this Agreement shall have
been terminated pursuant to Section 8.1 hereof, Purchaser agrees that it shall
not, without the consent of the Company, terminate or withdraw the Offer or
(except as provided in this Section 1.1(d)) extend the expiration date of the
Offer; provided, however, that, subject to the immediately following sentence,

                                      -3-

<PAGE>

without the consent of the Company, Purchaser shall have the right to terminate
or withdraw the Offer or extend the Offer from time to time if at the
then-scheduled expiration date of the Offer the conditions to the Offer
described in Annex I hereto shall not have been satisfied or earlier waived.
Unless this Agreement shall have been terminated pursuant to Section 8.1, if at
the then-scheduled expiration date of the Offer, the conditions to the Offer
described in Annex I hereto (other than the Minimum Condition) shall not have
been satisfied or earlier waived, upon the request of the Company, Purchaser
shall from time to time extend the expiration date of the Offer for up to a
maximum of 20 business days in the aggregate (it being understood and agreed
that the period from the Initial Expiration Date to and including the Extended
Expiration Date shall be counted in such 20-business-day period) for all such
extensions (the period of each such extension to be determined by Purchaser),
provided that at the time of such extension any such condition is reasonably
capable of being satisfied and provided further that the failure of any such
condition to be satisfied shall not result from a willful breach by the Company
of any of its covenants and agreements contained in this Agreement, until the
date Purchaser becomes obligated, pursuant to the terms of the Offer and this
Agreement, to accept for payment and pay for Shares tendered pursuant to the
Offer. Notwithstanding the foregoing, Purchaser may, without the consent of the
Company, extend the expiration date of the Offer (as it may be extended) for any
period required by applicable rules, regulations, interpretations or positions
of the SEC or the staff thereof applicable to the Offer or for any period
required by applicable law.

     SECTION 1.2. Company Action.

     (a) The Company hereby approves of and consents to the Offer and represents
and warrants that the Board of Directors, at a meeting duly called and held on
February 14, 2000, acting by the unanimous vote of those present: (i) approved
and adopted this Agreement and the transactions contemplated hereby, including
the Offer and the Merger, and the Stockholders Agreements; (ii) recommended that
the stockholders of the Company accept the Offer, tender their Shares pursuant
to the Offer and approve this Agreement and the transactions contemplated
hereby, including the Merger; and (iii) determined that this Agreement and the
transactions contemplated hereby, including the Offer and the Merger, are
advisable, fair to and in the best interests of the stockholders of the Company.

     (b) The Company hereby agrees to file with the SEC, as promptly as
practicable after the filing by Purchaser of the Schedule TO with respect to the
Offer but in any event on the date such Schedule TO is filed with the SEC, a
Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 (together
with any amendments or supplements thereto, the "Schedule 14D-9") that (i) will
comply in all material respects with the provisions

                                      -4-

<PAGE>

of all applicable Federal securities laws and (ii) will include the opinion of
the Company Financial Advisor referred to in Section 4.3(c) hereof. The Company
agrees to mail such Schedule 14D-9 to the stockholders of the Company along with
the Offer Documents promptly after the commencement of the Offer. The Company
agrees that the Schedule 14D-9 and the Offer Documents shall contain the
recommendations of the Board of Directors described in Section 1.2(a) hereof.
The Company agrees promptly to correct the Schedule 14D-9 if and to the extent
that it shall become false or misleading in any material respect (and each of
Parent and Purchaser, with respect to written information supplied by it
specifically for use in the Schedule 14D-9, shall promptly notify the Company of
any required corrections of such information and cooperate with the Company with
respect to correcting such information) and to supplement the information
contained in the Schedule 14D-9 to include any information that shall become
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading (and each of Parent and Purchaser
shall supplement the information provided by it specifically for use in the
Schedule 14D-9 to include any information that shall become necessary in order
to make the statements therein that are based on such provided information, in
light of the circumstances under which they were made, not misleading), and the
Company shall take all steps necessary to cause the Schedule 14D-9, as so
corrected or supplemented, to be filed with the SEC and disseminated to the
Company's stockholders, in each case to the extent required by applicable
Federal securities laws. Parent and its counsel shall be given a reasonable
opportunity to review and comment on the Schedule 14D-9 before it is filed with
the SEC.

     (c) In connection with the Offer, the Company shall promptly upon execution
of this Agreement furnish Parent with mailing labels containing the names and
addresses of all record holders of Shares, non-objecting beneficial owners list
and security position listings of Shares held in stock depositories, each as of
a recent date, and shall promptly furnish Parent with such additional
information, including updated lists of stockholders, mailing labels and
security position listings, and such other information and assistance as Parent
or its agents may reasonably request for the purpose of communicating the Offer
to the record and beneficial holders of Shares.

     SECTION 1.3. Directors. Promptly upon the purchase by Purchaser of any
Shares pursuant to the Offer, Parent shall be entitled to designate up to such
number of directors, rounded to the nearest whole number, on the Board of
Directors as will give Parent, subject to compliance with Section 14(f) of the
Exchange Act, representation on the Board of Directors equal to that number of
directors which equals the product of the total number of directors on the Board
of Directors (giving effect to the directors appointed or elected pursuant to
this sentence and including current directors serving as officers of the
Company) multiplied by the percentage that the aggregate number of Shares

                                      -5-

<PAGE>

beneficially owned by Parent or any affiliate of Parent (including for purposes
of this Section 1.3 such Shares as are accepted for payment pursuant to the
Offer, but excluding Shares held by the Company or any Subsidiary) bears to the
number of Shares outstanding. At such time, the Company will also cause, if
requested by Parent, (i) each committee of the Board of Directors, (ii) the
board of directors of each of the Subsidiaries and (iii) if requested by Parent,
each committee of such board to include persons designated by Parent
constituting up to the same percentage of each such committee or board as
Parent's designees constitute on the Board of Directors. The Company shall, upon
request by Parent, promptly take all actions necessary to cause Parent's
designees to be elected or appointed to the Board of Directors in accordance
with the terms of this Section 1.3, including, without limitation, increasing
the size of the Board of Directors and/or securing the resignations of such
number of directors as is necessary to enable Parent's designees to be elected
to the Board of Directors in accordance with the terms of this Section 1.3;
provided, however, that, in the event that Parent's designees are appointed or
elected to the Board of Directors, until the Effective Time (as defined in
Section 2.2(b) hereof) the Board of Directors shall have at least two directors
who are directors on the date hereof and who are neither officers of the Company
nor designees, affiliates or associates (within the meaning of the Federal
securities laws) of Parent (two or more of such directors, the "Independent
Directors"); provided further, that if no Independent Directors remain, the
other directors shall designate one person to fill one of the vacancies who
shall be neither an officer of the Company nor a designee, affiliate or
associate of Parent, and such person shall be deemed to be an Independent
Director for purposes of this Agreement. The Company represents and warrants to
Parent and Purchaser that nothing contained in the Stipulation and Settlement
Agreement dated December 15, 1999 settling Corcoran v. GRC International, Inc.
(C.A. No.: 17239) and Corcoran v. Denman, et al. (C.A. No.: 17490) in the
Delaware Court of Chancery, New Castle County (the "Settlement Agreement")
prohibits the Company from complying with its obligations under this Section 1.3
(it being understood that the Settlement Agreement restricts the manner in which
the Company may comply with this Section 1.3 by (i) limiting the size of the
Board of Directors to 13 directors and (ii) prescribing the classes into which
certain directors must be placed). Subject to applicable law, the Company shall
promptly take all action necessary pursuant to Section 14(f) of the Exchange Act
and Rule 14f-1 promulgated thereunder in order to fulfill its obligations under
this Section 1.3 and shall include in the Schedule 14D-9 mailed to stockholders
promptly after the commencement of the Offer (or an amendment thereof or an
information statement pursuant to Rule 14f-1 if Parent has not theretofore
designated directors or timely provided the requisite information) such
information with respect to the Company and its officers and directors as is
required under Section 14(f) and Rule 14f-1 in order to fulfill its obligations
under this Section 1.3. Parent will supply the

                                      -6-

<PAGE>

Company any information with respect to itself and its nominees, officers,
directors and affiliates required by Section 14(f) and Rule 14f-1.
Notwithstanding anything in this Agreement to the contrary, following the time

     SECTION 2.6. Conversion of Securities. At the Effective Time, by virtue of
the Merger and without any action on the part of Purchaser, the Company or the
holder of any of the following securities:

     (a) Each Share issued and outstanding immediately prior to the Effective
Time (other than any Shares to be canceled pursuant to Section 2.6(b) and any
Dissenting Shares (as defined in Section 2.7(a)) shall be canceled and be
converted into the right to receive the Per Share Amount in cash payable to the
holder thereof, without interest, upon surrender of the certificate representing
such Share. Each holder of a certificate representing any such Shares shall
cease to have any rights with respect thereto, except the right to receive the
Per Share Amount, without interest, upon the surrender of such certificate in
accordance with Section 2.8 hereof.

     (b) Each Share held in the treasury of the Company or owned by any
Subsidiary and each Share owned by Parent or any direct or indirect wholly owned
subsidiary of Parent immediately prior to the Effective Time shall be canceled
and no payment or other consideration shall be made with respect thereto.

     (c) Each share of common stock, $.0l par value, of Purchaser issued and
outstanding immediately prior to the Effective Time shall be converted into and
thereafter represent one validly issued, fully paid and nonassessable share of
common stock, $.0l par value, of the Surviving Corporation.

     SECTION 2.7. Dissenting Shares.

     (a) Notwithstanding any provision of this Agreement to the contrary, Shares
that are outstanding immediately prior to the Effective Time and that are held
by any stockholder who has not voted in favor of or consented to the Merger and
who duly demands appraisal of his Shares pursuant to the DGCL and complies with
all the provisions of the DGCL concerning the right of holders of Shares to
demand appraisal of their Shares in connection with the Merger (collectively,
the "Dissenting Shares") shall not be converted into the right to receive cash
pursuant to Section 2.6, but shall become the right to receive such cash
consideration as may be determined to be due to such stockholder as provided in
the DGCL. If, however, such stockholder withdraws his demand for appraisal or
fails to perfect or otherwise loses his right of appraisal, in any case pursuant
to the DGCL, his Shares shall be deemed to be converted as of the Effective Time
into the right to receive cash pursuant to Section 2.6(a) hereof, without any
interest thereon, upon surrender of the certificate or certificates representing
such Shares.

     (b) The Company shall give Parent (i) prompt notice of any demands for
appraisal of Shares received by the Company and (ii) the opportunity to
participate in and direct all

                                      -9-

<PAGE>

negotiations and proceedings with respect to any such demands. The Company shall
not, without the prior written consent of Parent, make any payment with respect
to, or settle, offer to settle or otherwise negotiate, any such demands.

     (c) Each Dissenting Share, if any, shall be canceled after payment in
respect thereof has been made to the holder thereof pursuant to the DGCL.

     SECTION 2.8. Surrender of Shares; Stock Transfer Books.

     (a) Before the Effective Time, Parent shall designate a bank or trust
company who shall be reasonably satisfactory to the Company to act as paying
agent in the Merger (the "Exchange Agent") to receive the funds necessary to
make the payments contemplated by Section 2.6. Parent shall, from time to time,
make available or cause to be made available to the Exchange Agent funds in
amounts and at times necessary for the payments under Section 2.8(b) to which
holders of Shares shall be entitled at the Effective Time pursuant to Section
2.6. Such funds shall be invested by the Exchange Agent as directed by Parent.
Any net profits resulting from, or interest or income produced by, such
investments shall be payable as directed by Parent.

     (b) As soon as reasonably practicable after the Effective Time, the
Surviving Corporation shall cause the Exchange Agent to mail to each holder of
record of a certificate or certificates that immediately prior to the Effective
Time represented Shares (the "Certificates"), (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent and shall be in a form and have such other provisions as Parent may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for the Merger consideration as provided in Section
2.6(a). Upon surrender of a Certificate for cancellation to the Exchange Agent
or to such other agent or agents as may be appointed by Parent, together with
such letter of transmittal, duly executed, and such other documents as may
reasonably be required by the Exchange Agent, the holder of such Certificate
shall be entitled to receive in exchange therefor the amount of cash, without
interest, into which the Shares theretofore represented by such Certificate
shall have been converted pursuant to Section 2.6(a), and the Certificate so
surrendered shall forthwith be canceled. Until so surrendered, each such
Certificate (other than Certificates representing Dissenting Shares and
Certificates representing Shares to be canceled pursuant to Section 2.6(b))
shall represent solely the right to receive the aggregate Per Share Amount,
without interest, relating thereto.

     (c) If payment of cash in respect of canceled Shares is to be made to a
Person other than the Person in whose name a

                                      -10-

<PAGE>

surrendered Certificate is registered, it shall be a condition to such payment
that the Certificate so surrendered shall be properly endorsed or shall be
otherwise in proper form for transfer and that the Person requesting such
payment shall have paid any transfer and other taxes required by reason of such
payment in a name other than that of the registered holder of the Certificate
surrendered or shall have established to the satisfaction of Parent or the
Exchange Agent that such tax either has been paid or is not payable. If a
mutilated Certificate is surrendered to the Exchange Agent or if the holder of a
Certificate submits an affidavit to the Exchange Agent stating that the
Certificate has been lost, destroyed or wrongfully taken, such holder shall, if
required by the Surviving Corporation, furnish an indemnity bond sufficient in
the reasonable judgment of the Surviving Corporation to protect Parent, the
Surviving Corporation and the Exchange Agent from any loss that any of them may
suffer.

     (d) All cash paid upon the surrender of Certificates in accordance with the
terms of this Article II shall be deemed to have been paid in full satisfaction
of all rights pertaining to the Shares theretofore represented by such
Certificates. At the Effective Time, the stock transfer books of the Company
shall be closed and thereafter there shall not be any further registration of
transfers of Shares that were outstanding immediately prior to the Effective
Time on the records of the Surviving Corporation. If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be canceled
and exchanged for cash as provided in Section 2.6(a) and this Section 2.8. No
interest shall accrue or be paid on any cash payable upon the surrender of a
Certificate or Certificates.

     (e) Promptly following the date which is six months after the Effective
Time, the Exchange Agent shall deliver to Parent all cash, certificates and
other documents in its possession relating to the transactions contemplated
hereby, and the Exchange Agent's duties shall terminate. Thereafter, each holder
of a Certificate (other than Certificates representing Dissenting Shares and
Certificates representing Shares to be canceled pursuant to Section 2.6(b))
shall look only to the Surviving Corporation (subject to abandoned property,
escheat or other similar laws) and only as general creditors thereof, with
respect to any Merger consideration that may be payable upon due surrender of
the Certificates held by such holder. Notwithstanding the foregoing, none of
Parent, Purchaser, the Company or the Exchange Agent shall be liable to any
Person in respect of any cash delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.

     (f) Parent or the Exchange Agent shall be entitled to deduct and withhold
from the consideration otherwise payable pursuant to this Agreement to any
holder of Shares such amounts as Parent or the Exchange Agent is required to
deduct and

                                      -11-

<PAGE>

withhold with respect to the making of such payment under the Internal Revenue
Code of 1986, as amended (the "Code") or under any provision of state, local or
foreign tax law. To the extent that amounts are so withheld by Parent or the
Exchange Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the Shares in respect of which
such deduction and withholding was made by the Parent or the Exchange Agent.

     SECTION 2.9. Stock Plans. (a) Options Outstanding. The Company currently
maintains the GRC International, Inc. 1985 Employee Stock Option Plan, the GRC
International, Inc. 1994 Employee Stock Option Plan, the GRC International, Inc.
1998 Employee Stock Option Plan, the GRC International, Inc. Cash Compensation
Replacement Plan, and the GRC International, Inc. Directors Fee Replacement Plan
(collectively referred to as the "Stock Plans"), more specifically described in
Section 4.2, which provide for the granting of options to purchase and awards of
Company Common Stock, and the GRC International, Inc. 1985 Employee Stock
Purchase Plan ("ESPP"), which permits employees to purchase Company Common
Stock. As of the date of this Agreement, the Company has taken all actions
necessary to amend each Stock Plan and the ESPP to provide that no further
options, awards or rights to receive equity shall be granted, offered or elected
under any Stock Plan after the date hereof. As of the date of this Agreement,
the Company has taken all actions necessary to cause the GRC International, Inc.
Cash Compensation Replacement Plan, the GRC International, Inc. Directors Fee
Replacement Plan, and the ESPP to terminate, and all participant contributions
and deferral amounts credited on behalf of the participants under such plans at
the time of such termination shall be paid to them in cash by the Company as
soon as administratively practicable thereafter.

     (b) Conversion of Options. The Board of Directors of the Company has
adopted an amendment to provide that the Stock Plans are amended so that upon
the consummation of the Offer each then outstanding and unexercised option to
purchase shares of Company Common Stock granted under any of the Stock Plans
(the "Options"), whether or not then exercisable or vested, shall be converted
into an obligation of the Company to pay, and a right of the holder thereof to
receive in full satisfaction of such Option, cash in an amount in respect
thereof equal to the product of (A) the excess, if any, of the Per Share Amount
over the exercise price thereof and (B) the number of shares of Company Common
Stock subject to such Option, less any income or employment tax withholding
required under the Code or any provision of foreign, state or local law.

     GRC International, Inc. 1985 Employee Stock Option Plan, the GRC
     International, Inc. 1994 Employee Stock Option Plan or the GRC
     International, Inc. 1998 Stock Option Plan (the "Option Plans") that is
     fully vested and exercisable as of the consummation of the Offer, the
     Company shall make the payment of the amount determined pursuant to Section
     2.9(b) above as soon as reasonably practicable following the consummation
     of the Offer.

          (ii) With respect to each Option granted pursuant to the terms of an
     Option Plan that is not vested and exercisable as of the consummation of
     the Offer, the Company or the Surviving Corporation, as applicable, shall
     make the payment of the amount determined pursuant to Section 2.9(b) above
     at the time each such unvested Option would otherwise have become vested
     and exercisable subject to the satisfaction of the terms and conditions set
     forth in the applicable option award agreement and the Option Plan pursuant
     to which such Option was granted, or at such earlier date as may be
     determined by Parent in its sole and absolute discretion; provided,
     however, if such holder's employment or service with the Company or any
     Subsidiary is involuntarily terminated by the Company or any Subsidiary for
     reasons other than Cause (as defined in Section 9.4), all of such holder's
     Options shall become vested upon such termination of employment or service,
     and the Company or the Surviving Corporation, as applicable, shall make the
     payment of the amount determined pursuant to Section 2.9(b) as soon as
     reasonably practicable following such termination. For purposes of this
     Section 2.9(c)(ii), a termination of employment by an Option holder, after
     the consummation of the Offer, following (A) a material decrease in such
     holder's base salary, (B) a relocation of such holder's principal place of
     employment to a location that increases his or her commute by more than 30
     miles from such holder's commute to his or her principal place of
     employment prior to the consummation of the Offer or (C) a non-employee
     director's cessation of service on the Board of Directors upon the request
     of the Company or the Surviving Corporation, as applicable, shall be deemed
     to be an involuntary termination.

          (iii) With respect to each Option granted pursuant to the terms of the
     GRC International, Inc. Cash Compensation Replacement Plan or the GRC
     International, Inc. Directors Fee Replacement Plan, whether or not such
     Option is vested and exercisable as of the consummation of the Offer, the
     Company shall make the payment of the amount determined pursuant to Section
     2.9(b) above as soon as reasonably practicable following the consummation
     of the Offer.

                                      -13-

<PAGE>

          (iv) Parent shall from time to time provide the Company or the
     Surviving Corporation, as applicable, with sufficient funds to satisfy the
     obligations of the Company or the Surviving Corporation, as applicable,
     under this Section 2.9.

     (d) Directors Retirement Plan. The Company has recently terminated the GRC
International, Inc. Directors Retirement Plan (the "Director Retirement Plan").
In exchange for their benefits under such plan, certain directors of the Company
received the right to receive shares of Company Common Stock ("Deferred Stock
Units") subsequent to their resignation from the Board of Directors. Immediately
following the consummation of the Offer, each Deferred Stock Unit shall be
converted into the right to receive cash in an amount equal to the product of
(A) the Per Share Amount and (B) the number of Deferred Stock Units held by each
such director, which cash amount shall be payable as soon as practicable
following the director's cessation of service on the Board of Directors.

under this Agreement. No waivers, consents, approvals or authorizations of any
Governmental Entity are required to be obtained or made by the Company in
connection with its execution, delivery or performance of this Agreement or the
consummation of the transactions contemplated hereby, except (i) where the

Schedule 4.7 hereto, neither the Company nor any of its Subsidiaries nor any of
their property is subject to any material order, judgment, injunction or decree.

     SECTION 4.8. Employee Benefit Plans.

     (a) (i) Schedule 4.8 sets forth a list of all "employee benefit plans", as
defined in Section 3(3) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA"), and all other employee benefit or executive compensation
arrangements, perquisite programs or payroll practices, including, without
limitation, any such arrangements or payroll practices providing severance pay,
sick leave, vacation pay, salary continuation for disability, retirement
benefits, deferred compensation, bonus pay, incentive pay, stock options
(including those held by directors, employees, and consultants), hospitalization
insurance, medical insurance, life insurance, scholarships or tuition
reimbursements, that are maintained by the Company, any Subsidiary or any entity
within the same "controlled group" as the Company or Subsidiary, within the
meaning of Section 4001(a)(14) of ERISA (a "Company ERISA Affiliate") or to
which the Company, any Subsidiary or Company ERISA Affiliate is obligated to
contribute thereunder for current or former employees or directors of the
Company, any Subsidiary or Company ERISA Affiliate (the "Company Employee
Benefit Plans").

          (ii) Schedule 4.8(a)(ii) sets forth, with respect to each Option that
     is outstanding under the Option Plans as of January 31, 2000, the name of
     the holder of such Option, the number of shares of Company Common Stock
     subject to such Option, the exercise price per share of such Option and the
     date on which such Options vest or become exercisable (it being understood
     that Schedule 4.8(a)(ii) does not include information concerning the
     Warrants).

     (b) None of the Company Employee Benefit Plans is a "multiemployer plan",
as defined in Section 4001(a)(3) of ERISA (the "Company Multiemployer Plan") or
a plan that has two or more contributing sponsors at least two of whom are not
under common

                                      -24-

<PAGE>

control, within the meaning of Section 4063 of ERISA. Neither the Company, any
Subsidiary nor any Company ERISA Affiliate has withdrawn in a complete or
partial withdrawal from any Company Multiemployer Plan, nor has any of them
incurred any liability due to the termination or reorganization of a Company
Multiemployer Plan. The aggregate withdrawal liability from each of such Company
Multiemployer Plan would not exceed $0.

     (c) None of the Company Employee Benefit Plans is a "single employer plan",
as defined in Section 4001(a)(15) of ERISA, that is subject to Title IV of
ERISA. Neither the Company, any Subsidiary nor any Company ERISA Affiliate has
incurred any outstanding liability under Section 4062 of ERISA to the Pension
Benefit Guaranty Corporation or to a trustee appointed under Section 4042 of
ERISA. Neither the Company, any Subsidiary nor any Company ERISA Affiliate has
engaged in any transaction described in Section 4069 of ERISA. Except as set
forth on Schedule 4.8 hereto, neither the Company nor any Subsidiary maintains,
or is required, either currently or in the future, to provide life, health,
medical or other welfare benefits to employees, directors, former employees,
former directors, or retirees after their termination of employment or service,

1985. The Company and each Subsidiary have reserved the right to amend,
terminate or modify at any time all plans or arrangements providing for retiree
health or life insurance coverage.

     (d) Except as set forth in Schedule 4.8, each Company Employee Benefit Plan
that is intended to qualify under Section 401 of Internal Revenue Code of 1986,
as amended (the "Code"), and each trust maintained pursuant thereto, has been
determined to be exempt from federal income taxation under Section 501 of the
Code by the IRS, and, to the Company's knowledge, nothing material has occurred
with respect to the operation of any such Company Employee Benefit Plan that is
reasonably likely to cause the loss of such qualification or exemption or the
imposition of any material liability, penalty or tax under ERISA or the Code, or
the assertion of material claims by participants (as that term is defined in
section 3(7) of ERISA) other than routine benefit claims.

     (e) All contributions (including all employer contributions and employee
salary reduction contributions) required to have been made under any of the
Company Employee Benefit Plans to any funds or trusts established thereunder or
in connection therewith have been made by the due date thereof.

     (f) There has been no material violation of ERISA or the Code with respect
to the filing of applicable reports, documents and notices regarding the Company
Employee Benefit Plans with the Secretary of Labor or the Secretary of the
Treasury or the furnishing of required reports, documents or

                                      -25-

<PAGE>

notices to the participants or beneficiaries of the Company Employee Benefit
Plans.

     (g) None of the Company, the Subsidiaries, the officers or directors of the
Company or any of the Subsidiaries or the Company Employee Benefits Plans which
are subject to ERISA, any trusts created thereunder or any trustee or
administrator thereof, has engaged in a "prohibited transaction" (as such term
is defined in Section 406 of ERISA or Section 4975 of the Code) or any other
breach of fiduciary responsibility that could subject the Company, any of the
Subsidiaries or any officer or director of the Company or any of the
Subsidiaries to any material tax or penalty on prohibited transactions imposed
by such Section 4975 or to any material liability under Section 502(i) or (1) of
ERISA.

     (h) The Company has no Company-owned life insurance policies currently in
force.

     (i) True, correct and complete copies of the following documents, with
respect to each of the Company Employee Benefit Plans, have been delivered or
made available to Parent by the Company: (i) all Company Employee Benefit Plans
and related trust documents, and amendments thereto; (ii) the most recent Forms
5500 (iii) summary plan descriptions; and (iv) any other documents, records or
materials as may be reasonably requested by the Parent.

     (j) There are no pending actions, claims or lawsuits which have been
asserted, instituted or, to the Company's knowledge, threatened, against the
Company Employee Benefit Plans, the assets of any of the trusts in their
capacity as such under such plans or the plan sponsor or the plan administrator,
or against any fiduciary of the Company Employee Benefit Plans with respect to
the operation of such plans (other than routine benefit claims).

     (k) All Company Employee Benefit Plans subject to ERISA or the Code have
been maintained and administered, in all material respects, in accordance with
their terms and with all provisions of ERISA and the Code, respectively,
(including rules and regulations thereunder) and other applicable federal and
state laws and regulations.

     (l) Except as set forth and excepted in Schedule 4.8(l) and Sections 2.9,
6.10 and 6.11, neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby (either alone or in
conjunction with any other event) will (i) result in any payment (including,
without limitation, severance, unemployment compensation, "excess parachute
payment" (within the meaning of Section 280G of the Code), forgiveness of
indebtedness or otherwise) becoming due to any director or any employee of the
Company or any Subsidiary under any Company Employee Benefit Plan or otherwise;
(ii)

                                      -26-

<PAGE>

materially increase any benefits otherwise payable under any Company Employee
Benefit Plan; (iii) result in any acceleration of the time of payment or vesting
of any such benefits; (iv) limit or prohibit the ability to amend or terminate
any Company Employee Benefit Plan; (v) require the funding of any trust or other
funding vehicle; or (vi) renew or extend the term of any agreement in respect of
compensation for an employee of the Company which would create any liability to
the Company or Purchaser or their respective affiliates after consummation of
the Offer.

     SECTION 4.9. Labor and Employment. (a) Except as disclosed in Schedule

Company nor any of its Subsidiaries is a party to any written, oral or implied
contract or agreement with any current or former officer or director of the
Company or any Subsidiary, or any independent contractor relating to the
employment or service of any such person which to the Company's knowledge is
reasonably likely to result in any material liability to or obligation of the
Company after the Closing Date. The Company has delivered to Parent true and
complete copies of all such contracts or agreements or detailed descriptions of
individual agreements (or, in the case of any contract or agreement that is not

Except as set forth on Schedule 4.10(c), neither the Company nor any of the
Subsidiaries is, nor to the knowledge of the Company is any other party, in
material breach of any lease agreement to which the Company or any Subsidiary is
a party (the "Company Leases"). The execution and delivery of this Agreement and
the performance of the Company's obligations under this Agreement and the
consummation of the transactions contemplated hereby will not (i) constitute a
breach by the Company or any Subsidiary under any Company Leases (ii) give rise
to any right of any third party to terminate any Company Lease, or (iii) cause a
loss or impairment of rights under any Company Lease, except for any such
breaches, terminations, losses or impairments as would not, individually or in
the aggregate, have a Material Adverse Effect. All the material buildings,

Subsidiaries (whether owned or leased) are in normal operating condition (normal
wear and tear excepted) and are fit for use in the ordinary course of business
of the Company. Notwithstanding anything to the contrary, no representations or

utilized by the Company or any Subsidiary in the conduct of its and their
businesses and good title to or, with respect to items not owned by the Company

collectively referred to as the "Company Intellectual Property"). The Company
has no knowledge of any infringement by others of Intellectual Property owned by
the Company or any Subsidiary nor the misappropriation of any trade secrets
owned by the Company or any Subsidiary, except where such infringement or
misappropriation would not, individually or in the aggregate, have a Material
Adverse Effect. To the Company's knowledge, the conduct of the businesses of the
Company and the Subsidiaries does not infringe on any Intellectual Property
rights of others nor does it involve the misappropriation of any trade secrets
of others, except where

                                      -29-

<PAGE>

such infringement or misappropriation would not, individually or in the
aggregate, have a Material Adverse Effect.

individually or in the aggregate, have a Material Adverse Effect, with respect
to each item of Company Intellectual Property: (i) if the Company or any
Subsidiary has held itself out as the owner thereof or otherwise developed or
caused the development of the item, the Company or its Subsidiaries exclusively
possess all rights, title and interest in and to the item; and (ii) no charge,

the Company's and each Subsidiary's rights in all inventions, processes,
designs, formulae, know-how, trade secrets and other confidential information of
the Company and each Subsidiary, and have taken reasonable steps to enforce
rights in Intellectual Property owned by the Company or any Subsidiary against
known infringement by third parties. The Company and each Subsidiary have taken
reasonable steps, including all steps that the Company or any Subsidiary may be
contractually obligated to undertake, to protect confidential information or
trade secrets provided by another Person to the Company or any Subsidiary.

     (d) Except as set forth on Schedule 4.11, neither this Agreement nor the
assignment to Parent or the Surviving Corporation, by operation of law or
otherwise, of title to or the rights to use any or all of the Company
Intellectual Property will to the Company's knowledge after the Effective Time
(a) cause or result in an infringement or misappropriation of any Intellectual
Property right of any Person; (b) prevent the Surviving Corporation or its
assignee (provided that such assignee has the necessary national security
clearance and is allowed access to and use of such Company Intellectual Property
by the U.S. Government) from using the Company Intellectual Property in
substantially the same manner as it is used by the Company and each Subsidiary
prior to the Effective Time (other than by virtue of agreements, relationships
or the status of Parent and its affiliates); or (c) subject Parent or the

third party in excess of those payable by the Company or any Subsidiary,

Company with respect to any such policy. All premiums due on such policies have
been paid in a timely manner, and the Company and the Subsidiaries have complied
in all material respects with the terms and provisions of such policies. The
insurance coverage provided by such policies is adequate and customary for the
industry in which the Company and the Subsidiaries operate.

5.1(m) or any action which would result in any of the conditions set forth in
Annex I not being satisfied.

     SECTION 5.2. No Solicitation.

     (a) Except as set forth in this Section 5.2, neither the Company nor any of
its affiliates controlled by it shall (and each shall use its best efforts to
cause its respective officers, directors, employees, representatives and agents,
including, but not limited to, investment bankers, attorneys and accountants
(collectively, "Agents"), not to), directly or indirectly, encourage, solicit,
participate in or initiate discussions or negotiations with, or provide any
information to, any Person (other than Parent, any of its affiliates or Agents)
concerning any proposal or offer (in each case, whether or not in writing and
whether or not delivered to the stockholders of the Company generally) to
acquire in any manner, directly or indirectly, all or a substantial part of the
assets or business and properties of the Company or any of its Subsidiaries or
any capital stock of or other equity interest in the Company or any of its
Subsidiaries, whether by merger, tender offer, exchange offer, sale of assets or

operating or principal business unit of the Company, other than pursuant to the
transactions contemplated by this Agreement (collectively, an "Acquisition
Proposal"). Except as provided in this Section 5.2, the Company shall not have
any activities, discussions or negotiations with any Person with respect to any
of the foregoing. A "Superior Proposal" is an Acquisition Proposal that involves
payment of consideration to the Company's stockholders that is financially
superior to that payable in the Offer and the Merger. The Company, its
affiliates and their respective Agents shall immediately cease any existing
discussions or negotiations, if any, with any Persons conducted heretofore with
respect to any Acquisition Proposal.

     (b) Prior to the Share Purchase Date, the Company may furnish information
concerning its business, properties or assets to any Person in response to a
request for such information made after the date of this Agreement which was not
encouraged, solicited or initiated, directly or indirectly, by the Company or
any of its affiliates or their respective Agents after the date of this
Agreement, and may participate in discussions and negotiations with such Person
concerning an Acquisition Proposal, in each case if and only to the extent that
(x) such Person has submitted a written Acquisition Proposal to the Board of
Directors relating to such transaction, (y) the Board of Directors determines in
good faith (i) after consulting with its independent financial advisors, (A)
that such Person is reasonably capable of consummating such Acquisition
Proposal, taking into account the legal, financial, regulatory and other aspects
of such Acquisition Proposal and the Person making such Acquisition Proposal and
(B) such Acquisition Proposal is reasonably likely to be a Superior Proposal and
(ii) after

                                      -42-

<PAGE>

receipt of advice from outside legal counsel to the Company, that failure to
take such action would be inconsistent with its fiduciary duties under
applicable law, and (z) such Person has signed a confidentiality agreement
substantially identical to the Confidentiality Agreement. The Company will
promptly provide to Parent any written material information regarding the
Company provided to such Person which was not previously provided or otherwise
made available to Parent.

     (c) The Company will promptly following receipt of an Acquisition Proposal
(and in any event not later than 24 hours after receipt thereof) notify Parent
of the receipt of the Acquisition Proposal and shall in such notice indicate in
reasonable detail the identity of the offeror and the material terms and
conditions of any proposal and shall keep Parent promptly advised of the status
and material terms of any such inquiry, offer or proposal.

     (d) The Board of Directors may withdraw or modify its approval or
recommendation of the Offer and/or the Merger, provided (i) the Board of
Directors determines in good faith, after receipt of advice from outside legal
counsel to the Company, that the failure to do so would be inconsistent with its
fiduciary duties to the Company's stockholders under applicable law, and (ii)
the Company notifies Parent of any such withdrawal or modification prior to its
release to the public.

     (e) Nothing contained in this Section 5.2 or any other provision hereof
shall prohibit the Company or the Board of Directors from (i) taking and
disclosing to the Company's stockholders a position with respect to a tender or
exchange offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated
under the Exchange Act, or (ii) making such disclosure to the Company's
stockholders as, in the good faith judgment of the Board of Directors, after
receiving advice from outside counsel, is required under applicable law,
provided that the Board of Directors may not, except as permitted by Section
5.2(d), withdraw or modify its approval or recommendation of the Offer or the
Merger.

     (f) Nothing contained in this Section 5.2 shall prohibit Purchaser from
purchasing Shares pursuant to the Offer or consummating the Merger.

                                   Article VI.

                              ADDITIONAL AGREEMENTS

     SECTION 6.1. Proxy Statement. As promptly as practicable after the
consummation of the Offer and if required by the Exchange Act, the Company shall
prepare and file with the SEC, and shall use all reasonable efforts to have

Proxy Statement. The Proxy Statement shall contain the recommendation of the
Board of Directors that the Company's stockholders approve this Agreement and

consummation of the Offer, the Company shall promptly take all action necessary

convene the Company Stockholders' Meeting, if such meeting is required. The
stockholder vote required for approval of the Merger will be no greater than
that set forth in the DGCL. The Company shall use its reasonable efforts to
solicit from stockholders of the Company proxies in favor of the Merger and
shall take all other action necessary or, in the reasonable opinion of Parent,
advisable to secure any vote of stockholders required by the DGCL to effect the
Merger. Notwithstanding the foregoing, if Purchaser or any other subsidiary of
Parent shall acquire at least 90 percent of the outstanding Shares, and provided
that the conditions set forth in Article VII shall have been satisfied or
waived, the Company shall, at the request of Parent, take all necessary and
appropriate action to cause the Merger to become effective as soon as
practicable after such acquisition, without the approval of the stockholders of
the Company, in accordance with Section 253 of the DGCL.

     SECTION 6.3. Compliance with Law. Each of the Company, Parent and Purchaser
will comply in all material respects with all applicable laws and with all
applicable rules and regulations of any Governmental Entity in connection with
its execution, delivery and performance of this Agreement and the transactions
contemplated hereby.

     SECTION 6.4. Notification of Certain Matters. The Company shall give prompt
notice to Parent (A) of the occurrence, or non-occurrence of any event whose
occurrence, or non-occurrence would be likely to cause (i) any representation or
warranty contained in this Agreement to be untrue or inaccurate in any respect
at any time from the date hereof to the Effective Time, (ii) any condition set
forth in Annex I to be unsatisfied in any material respect at any time from the
date hereof to the date Parent purchases Shares pursuant to the Offer or (iii)
any covenant, condition or agreement contained in this Agreement not to be
complied with or satisfied in all material respects; and (B) any failure by the
Company to comply with in all material respects any of its covenants or
agreements hereunder; provided, however, that the delivery of any notice
pursuant to this Section 6.4 shall not limit or otherwise affect the remedies
available to Parent hereunder. The Company shall give prompt notice to Parent of
any notice or other communication from any third party alleging that the consent
of such third party is or may be required in connection with the transactions
contemplated by this Agreement.

reasonable times to their respective Agents, properties, offices and other
facilities and to all books, records and contracts, and shall promptly furnish
Parent and Purchaser with (a) all financial, operating and other data and
information as Parent or Purchaser, through its Agents, may reasonably request
and (b) a copy of each report, schedule and other document filed or received by
the Company or any of the Subsidiaries during such period pursuant to the
requirements of applicable securities or federal Tax laws.

     SECTION 6.6. Public Announcements. So long as this Agreement is in effect,
Parent and the Company shall consult with each other before issuing, and provide
each other a reasonable opportunity to review and comment upon, any press
release or other public statements with respect to the Offer or the Merger and
shall not issue, or permit their affiliates to issue, any such press release or
make any such public statement prior to such consultation, except as may be
required by law or in accordance with any listing agreement with any securities
exchange on which such party's securities are listed.

     SECTION 6.7. Reasonable Best Efforts; Cooperation. Upon the terms and
subject to the conditions hereof, each of the parties hereto shall use its
reasonable best efforts to obtain in a timely manner all necessary waivers,
consents and approvals and to effect all necessary registrations and filings,
and to use all reasonable best efforts to take, or cause to be taken, all other
actions and to do, or cause to be done, all other things necessary, proper or
advisable to consummate and make effective as promptly as practicable the
transactions contemplated by this Agreement, including, without limitation, (i)
cooperating in responding to inquiries from, and making presentations to,
regulatory authorities and customers, (ii) defending against and responding to

anything herein to the contrary, in connection with any filing or submission or
other action required to be made or taken by any party to effect the Merger and
all other transactions contemplated hereby, the Company shall not, without the
prior written consent of Parent, commit to any divestiture

                                      -45-

<PAGE>

transaction, and Parent shall not be required to divest or hold separate or
otherwise take or commence to take any action that, in the reasonable discretion
of Parent, limits its freedom of action with respect to, or its ability to
retain, the Company or any of the Company's affiliates or any material portion
of the Company's assets or businesses.

     SECTION 6.8. Agreement to Defend and Indemnify.

     (a) It is understood and agreed that, subject to the limitations on
indemnification contained in the DGCL, the Company shall, to the fullest extent
permitted under applicable law and regardless of whether the Merger becomes
effective, indemnify and hold harmless, and after the Effective Time, the
Surviving Corporation shall for a period of six years following the Effective
Time, to the fullest extent permitted under applicable law, and Parent shall,
for such six-year period, but only to the extent the Company or the Surviving
Corporation would be required or permitted under applicable law, indemnify and
hold harmless, each director and officer of the Company (collectively, the
"Indemnified Parties") from and against any costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages,
liabilities and amounts paid in settlement in connection with any claim, action,
suit, proceeding or investigation arising out of or pertaining to matters
relating to their duties or actions in their capacity as officers and directors
in connection with any of the transactions contemplated hereby and existing at
the Effective Time, including without limitation liabilities arising under the
Securities Act or the Exchange Act in connection with the Offer or the Merger,
and in the event of any such claim, action, suit, proceeding or investigation
(whether arising prior to or after the Effective Time), (i) the Company or the
Surviving Corporation shall advance the reasonable fees and expenses of counsel
selected by the Indemnified Parties, which counsel shall be reasonably
satisfactory to the Company or the Surviving Corporation, promptly as statements
therefor are received (provided the person to whom such expenses are advanced
provides a customary undertaking complying with applicable law to repay such
advances if it is ultimately determined that such person is not entitled to
indemnification), and (ii) the Company, Parent (but only after the consummation
of the Offer) and the Surviving Corporation will cooperate in the defense of any
such matter; provided, however, that none of the Company, Parent nor the
Surviving Corporation shall be liable for any settlement effected without its
prior written consent; and provided further that none of the Company, Parent nor
the Surviving Corporation shall be obliged pursuant to this Section 6.8 to pay
the fees and disbursements of more than one counsel for all Indemnified Parties
in any single action except to the extent that, in the opinion of counsel for
the Indemnified Parties, two or more of such Indemnified Parties have
conflicting interests in the outcome of such action. For six years after the
Effective Time, Parent shall cause to be maintained or obtained officers' and
directors' liability

                                      -46-

<PAGE>

insurance covering the Indemnified Parties who are currently covered by the
Company's officers and directors liability insurance policy with respect to
matters or events occurring prior to the Effective Time on terms not less
favorable than those in effect on the date hereof in terms of coverage and
amounts to the extent available; provided, however, that if the aggregate annual
premiums for such insurance at any time during such period exceed 150% of the
per annum rate of premium paid by the Company for such insurance as of the date
of this Agreement (which amounts under current policies are set forth on
Schedule 6.8), then Parent shall be required to provide the maximum coverage
that will then be available at an annual premium equal to 150% of such per annum
rate as of the date of this Agreement. The Surviving Corporation shall continue
in effect, without amendment, repeal or modification in any manner that would
adversely affect the rights of the persons entitled to the protections and
privileges thereof, the indemnification provisions provided on the date hereof
by the Company By-Laws for a period of not less than six years following the
Effective Time. This Section 6.8 shall survive the consummation of the Merger or
any termination of this Agreement pursuant to Section 8.1 hereof.
Notwithstanding anything in this Section 6.8 to the contrary, neither the
Company nor the Surviving Corporation shall have any obligation under this
Section 6.8 to indemnify any Indemnified Party against any cost, expense,
judgment, fine, loss, claim, damage, liability or settlement amount found to
have resulted solely from such Indemnified Person's own gross negligence or
willful misconduct. Notwithstanding Section 9.8 hereof, this Section 6.8 is
intended to be for the benefit of and to grant third-party rights to Indemnified
Parties whether or not parties to this Agreement, and each of the Indemnified
Parties shall be entitled to enforce the covenants contained in this Section
6.8.

     (b) If the Surviving Corporation or any of its successors or assigns (i)
consolidates with or merges into any other Person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger or
(ii) transfers all or substantially all of its properties and assets to any
Person, then and in each such case, proper provision shall be made so that the
successors and assigns of the Surviving Corporation assume the obligations set
forth in this Section 6.8.

     SECTION 6.9. Takeover Statutes. If any state takeover statute or other
similar statute or regulation becomes or is deemed to become applicable to the
Offer, the Merger, this Agreement or any of the transactions contemplated
hereby, the Company shall promptly take all action necessary to render such
statute or regulation inapplicable to all of the foregoing.

     SECTION 6.10. Employment Matters. The Company will, and will cause its
Subsidiaries to, and from and after the Effective Time the Surviving Corporation
will, honor, in accordance with their terms all existing employment and
severance agreements between the Company or any of its Subsidiaries and any

                                      -47-

<PAGE>

officer, director or employee of the Company or any of its Subsidiaries
specified in Schedule 6.10 hereto, including the obligation of the Company to
make any payment to any officer, director or employee on a date that is prior to
the Effective Time pursuant to the terms of any such employment agreement or
severance agreement. Notwithstanding anything contained herein to the contrary,
no such payments shall be made pursuant to the terms of the agreements with the
employees listed on Schedule 4.8(l) hereto without the prior consent of Parent,
which consent shall not be unreasonably withheld.

     SECTION 6.11. Company Employee Benefit Plans. (a) For the period commencing
at the consummation of the Offer until the first anniversary thereof, the
Company or the Surviving Corporation, as applicable, shall provide medical,
dental, vision care, life and disability insurance, severance, vacation and
"section 125" benefits for the employees of the Company and any Subsidiary as of
the consummation of the Offer (the "Employees") and their eligible dependents
that are substantially similar in the aggregate to those provided as of the date
of this Agreement under the Company Employee Benefit Plans listed on Schedule
6.11 hereto. Subject to the eligibility requirements thereof, as soon as
reasonably practicable following the Effective Time the Employees will become
eligible to participate in the Parent Employee Stock Purchase Plan and an
Employee's service with the Company and any Subsidiary prior to the Effective
Time will be recognized for purposes of determining eligibility to participate
in such plan.

     (b) For the period commencing at the consummation of the Offer until the
first anniversary thereof, the Company or the Surviving Corporation, as
applicable, shall provide benefits to the Employees under a defined contribution
plan with a cash-or-deferred arrangement providing benefits to the Employees,
including Company contributions, which are comparable to the benefits provided
to the Employees under the GRC International, Inc. Employees' Deferred Income
Plan as of the date of this Agreement (the "401(k) Plan"); provided that nothing
herein shall require the Company or the Surviving Corporation to provide or
permit investment in the securities of Parent or to continue to make available
the specific investment options currently available under the 401(k) Plan,
including without limitation any investment in Company Common Stock.

     (c) In the event the Company or any Subsidiary becomes a participating
company in the employee benefit plans of Parent, or an Employee otherwise
becomes employed by a company that participates in the employee benefit plans of
Parent (a "Participating Company"), Parent shall recognize, or shall cause the
Participating Company to recognize, each Employee's service with or recognized
by the Company and any Subsidiary as follows:

          (i) service prior to the Effective Time shall be recognized for
     purposes of determining eligibility to

                                      -48-

<PAGE>

     participate in the defined contribution plan and health and welfare plans
     then made available to the Employees generally, and for eligibility to
     receive matching contributions and vesting in matching contributions under
     any such defined contribution plan, but not for purposes of determining
     levels or amounts of benefits under any of Parent's disability or severance
     plans, or for vesting or benefit accruals under any of Parent's defined
     benefit plans, or for eligibility for post-employment medical, dental, life
     insurance or toll discount plans or programs;

          (ii) service after the Effective Time but prior to the date on which
     an Employee becomes employed by a Participating Company shall be recognized
     for purposes of determining levels or amounts of benefits under Parent's
     disability or severance plans in which such employee is then eligible to
     participate, and for vesting under Parent's defined benefit pension plan in
     which such employee is then eligible to participate, but not for purposes
     of benefit accruals under any defined benefit pension plan and not for
     eligibility for post-employment medical, dental, life insurance or toll
     discount plans or programs; and

          (iii) service after the date on which an Employee becomes employed by
     a Participating Company shall be recognized for all purposes under the
     employee benefit plans of Parent in which such employee is then eligible to
     participate.

     (d) Nothing contained in this Agreement shall be interpreted as (i)
preventing the Company, Parent or the Surviving Corporation from amending,
modifying or terminating any Company Employee Benefit Plan or other related
contract, arrangement, commitment or understanding in accordance with their
terms and applicable law or (ii) interfering with the Company's or the Surviving
Corporation's right or obligation to make such changes as are necessary to
comply with applicable law.

     (e) From and after the date hereof, all communications relating to the
Company Employee Benefit Plans, including, without limitation, the Stock Plans,
shall be subject to Parent's comment and approval prior to distribution, which
shall not be unreasonably withheld or delayed, and the Company shall cooperate
with and assist Parent in providing necessary or desirable communications to the
employees and directors of the Company regarding the transactions contemplated
hereby.

          (i) if any Person shall have made a bona fide written offer to acquire
     the Company which was not encouraged, solicited or initiated, directly or
     indirectly, by the Company or any of its affiliates or their respective
     Agents after the date hereof (A) that the Board of Directors determines in
     its good faith judgment is a Superior Proposal and (B) as a result of which
     the Board of Directors determines in good faith, after receiving advice
     from outside counsel to the Company, that failure to take such action would
     be inconsistent with its fiduciary duties under applicable law; provided,
     however, that not less than five business days prior to such termination,
     the Company shall notify Parent of its intention to terminate this
     Agreement

                                      -50-

<PAGE>

     pursuant to this Section 8.1(c)(i) and shall cause its respective financial
     and legal advisers to negotiate during such five-business-day period with
     Parent in an effort to make such adjustments in the terms and conditions of
     this Agreement as would enable the Company to proceed with the transactions
     contemplated herein on such adjusted terms (during which period Purchaser
     shall not accept for payment or purchase Shares pursuant to the Offer), and
     notwithstanding such negotiations and adjustments, the Board of Directors
     reasonably concludes, in its good faith judgment, that the transactions
     contemplated herein on such terms as adjusted, are not at least as
     favorable to the stockholders of the Company as such offer and provided
     that the Company shall have complied with the notice provisions of Section
     5.2(b); and provided, further, that such termination under this clause (i)
     shall not be effective until the Company has made payment of the full
     Termination Fee required by Section 8.2(b); or

          (ii) if as the result of the failure to be satisfied of any of the
     conditions set forth in Annex I, Parent or Purchaser shall have terminated
     the Offer or the Offer shall have expired without Purchaser having
     purchased any Shares pursuant thereto; provided, however, that the Company
     may not terminate this Agreement pursuant to this Section 8.1(c)(ii) if the
     failure of any such condition to be satisfied at the time of such
     termination results from (A) the Company's failure to perform any of its
     obligations under this Agreement or (B) facts or circumstances that
     constitute a breach of any representation or warranty of the Company under
     this Agreement; or

          (iii) if Parent, Purchaser or any of their affiliates shall have
     failed to commence the Offer in accordance with the first sentence of
     Section 1.1(a); provided, however, that the Company may not terminate this
     Agreement pursuant to this Section 8.1(c)(iii) if such failure to have
     commenced the Offer shall have been caused by (A) the Company's failure to
     perform any of its obligations under this Agreement or (B) facts or
     circumstances that constitute a breach of any representation or warranty of
     the Company under this Agreement; or

          (iv) if Parent or Purchaser shall have breached in any material
     respect any of its representations, warranties, covenants or other
     agreements contained in this Agreement which breach or failure to perform
     is incapable of being cured or has not been cured by the date that is 15
     business days following written notice thereof to Parent from the Company.

     (d) By Parent or Purchaser:

                                      -51-

<PAGE>

          (i) if prior to the purchase of any Shares pursuant to the Offer, the
     Board of Directors or any committee thereof shall have withdrawn, or
     modified or changed, or publicly proposed to withdraw, modify or change, in
     a manner adverse to Parent or Purchaser (including by amendment of the
     Schedule 14D-9) its approval or recommendation of the Offer, this Agreement
     or the Merger or shall have approved or recommended or publicly proposed to
     approve or recommend an Acquisition Proposal, or if the Board of Directors
     or any committee thereof fails to reaffirm publicly and unconditionally its
     recommendation to the Company's stockholders that they tender their Shares
     in the Offer, which public reaffirmation must be made within ten days after
     Parent's written request to do so (which request may be made at any time
     that an Acquisition Proposal is pending and not withdrawn) and must also
     include the unconditional rejection of such Acquisition Proposal (to the
     extent not previously withdrawn); or

          (ii) if Parent or Purchaser shall have withdrawn or terminated the
     Offer or the Offer shall have expired in accordance with its terms and the
     terms of this Agreement without Parent or Purchaser having purchased any
     Shares thereunder; provided that Parent or Purchaser may not terminate this
     Agreement pursuant to this Section 8.1(d)(ii) if Parent or Purchaser is in
     material breach of its obligations under this Agreement; or

          (iii) any Person or "group" (as defined in Section 13(d)(3) of the
     Exchange Act), other than Parent, Purchaser, or their affiliates or any
     group of which any of them is a member, shall have acquired beneficial
     ownership (as determined pursuant to Rule 13d-3 promulgated under the
     Exchange Act) of 25% or more of the Shares; provided that for purposes of
     this Section 8.1(d)(iii), none of Cilluffo Associates, L.P., Gerald
     McNichols or their respective affiliates or any group of which any of them
     is a member shall be deemed to have acquired 25% or more of the Shares
     solely by virtue of the execution, delivery or performance of the
     Stockholders Agreements; or

(iv) if the Company shall have breached any of its representations or warranties
     which breach would give rise to the failure of the condition set forth in
     clause (d) of Annex I hereto to be satisfied or if, prior to consummation
     of the Offer, the Company shall have failed to perform its covenants or
     other agreements contained in this Agreement which failure to perform would
     give rise to the failure of the condition set forth in clause (e) of Annex
     I hereto to be satisfied, which breach or failure to perform is incapable
     of being cured or has not been cured by the date that is 15 business days
     following written notice thereof to the Company from Parent.

banking moratorium or any suspension of payments in respect of banks in the
United States, (iii) any limitation (whether or not mandatory) by any
Governmental Entity on, or other event that materially and adversely affects,
the extension of credit by banks or other lending institutions or (iv) in the
case of any of the foregoing existing at the time of the execution of this
Agreement, a material acceleration or worsening thereof; or

     (g) the Board of Directors or any committee thereof (i) shall have
withdrawn, or modified or changed in a manner adverse to Parent or Purchaser
(including by amendment of the Schedule 14D-9) its approval or recommendation of
this Agreement or the transactions contemplated hereby, including the Offer or
the Merger, (ii) recommended or approved an Acquisition Proposal, (iii) shall
have adopted any resolution to effect any of the foregoing, or (iv) upon request
of Purchaser, shall fail to reaffirm publicly and unconditionally its approval
or recommendation of the Offer, this Agreement or the Merger within ten days
after Parent's written request to do so under the circumstances described in
Section 8.1(d)(i) of this Agreement; or

     (h) any Person or "group" (as defined in Section 13(d)(3) of the Exchange
Act), other than Parent, Purchaser, or their affiliates or any group of which
any of them is a member, shall have acquired beneficial ownership (as determined
pursuant to Rule 13d-3 promulgated under the Exchange Act) of 25% or more of the

of which any of them is a

                                      I-3

<PAGE>

member, shall be deemed to have acquired 25% or more of the Shares solely by
virtue of the execution, delivery or performance of the Stockholders Agreements;

which, in the judgment of Parent or Purchaser with respect to each and every
matter referred to above and regardless of the circumstances giving rise to any
such condition, makes it inadvisable to proceed with the Offer or with such
acceptance for payment of or payment for Shares or to proceed with the Merger.

     The foregoing conditions are for the sole benefit of Purchaser and may be
asserted by Purchaser regardless of the circumstances (including any action or
inaction by Parent or Purchaser) giving rise to any such conditions and may be
waived by Purchaser in whole or in part at any time and from time to time, in
their sole discretion subject to the terms of this Agreement. The failure by
Purchaser at any time to exercise any of the foregoing rights shall not be
deemed a waiver of any such right, the waiver of any such right with respect to
particular facts and circumstances shall not be deemed a waiver with respect to
any other facts and circumstances and each such right shall be deemed an ongoing
right which may be asserted at any time and from time to time. Terms used but
not defined herein shall have the meanings assigned to such terms in the
Agreement to which this Annex I is a part.

     WHEREAS, Parent, Sub and the Company are, concurrently with the execution
hereof, entering into an Agreement and Plan of Merger, dated as of February 14,
2000 (the "Merger Agreement"), pursuant to which, upon the terms and subject to
the conditions set forth in the Merger Agreement, Sub will make an offer (the
"Offer") to acquire all of the issued and outstanding shares of common stock,
par value $0.10 per share, of the Company (the "Company Common Stock"), at a
purchase price of $15.00 per share, net to the seller in cash, the consummation
of which will be followed by the merger of Sub with and into the Company, with
the Company being the surviving corporation (the "Merger");

     WHEREAS, Stockholder is the record and/or beneficial owner of 1,708,000
shares of Company Common Stock (collectively, the "Existing Shares") (all such
Existing Shares, together with all other shares of capital stock or other voting
securities of the Company or any of its Subsidiaries with respect to which

Exchange Act) as of the date of this Agreement, and any shares of capital stock
or other voting securities of the Company or any of its Subsidiaries, beneficial
ownership of which is directly or indirectly acquired after the date hereof,
including, without limitation, shares received pursuant to any stock splits,
stock dividends or distributions, shares acquired by purchase or upon the
exercise, conversion or exchange of any option, warrant or convertible security
or otherwise, and shares or any voting securities of the Company or any of its
Subsidiaries received pursuant to any change in the capital stock of the Company
or such Subsidiary by reason of any recapitalization, merger, reorganization,
consolidation, combination, exchange of shares or the like, are referred to
herein as the "Shares");

     WHEREAS, each of the parties hereto desires to enter into this Agreement to
provide for, among other things, (1) the obligation of Stockholder to tender, or
cause the record holder of the Shares to tender, the Shares beneficially owned
by Stockholder (other than Shares subject to unexercised options) (the "Tender
Shares") in the Offer, (2) the obligation of Stockholder to vote, or cause the
record holder of the Shares to vote, the Shares beneficially owned by
Stockholder (other than Shares subject to unexercised options) (the "Voting
Shares") in the manner specified herein and (3) certain restrictions on the sale
or the transfer of the record and beneficial ownership of Shares by Stockholder
(this Agreement and all other agreements, instruments and other documents
executed and delivered by Stockholder in connection with this Agreement are
collectively referred to as the "Support Documents"); and

     WHEREAS, Stockholder acknowledges that Parent and Sub are entering into the
Merger Agreement in reliance on the representations, warranties, covenants and
other agreements

<PAGE>

     of Stockholder set forth in this Agreement and would not enter into the
     Merger Agreement if Stockholder did not enter into this Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein and in
the Merger Agreement, and intending to be legally bound hereby, Parent, Sub and
Stockholder agree as follows:

     1. Defined Terms. Terms used herein without definition shall have the
meanings assigned to such terms in the Merger Agreement.

     2. Agreement to Tender. Stockholder hereby agrees to validly tender, or
cause the record owner to validly tender, all of the Tender Shares pursuant to
and in accordance with the terms of the Offer within 18 business days of the
commencement thereof, and not to withdraw or permit to be withdrawn any Shares
therefrom.

     3. Agreement to Vote. Stockholder hereby agrees that, from and after the
date hereof and until the Termination Date (as defined in Section 19), at any
meeting of the stockholders of the Company, however called, or in connection
with any written consent of the stockholders of the Company, Stockholder shall
appear at each such meeting, in person or by proxy, or otherwise cause the
Voting Shares to be counted as present thereat for purposes of establishing a
quorum, and Stockholder shall vote (or cause to be voted) or act by written
consent with respect to all of the Voting Shares that are beneficially owned by
Stockholder or as to which Stockholder has, directly or indirectly, the right to
vote or direct the voting, (a) in favor of adoption and approval of the Merger
Agreement and the Merger and the approval of the terms thereof and each of the
other actions contemplated by the Merger Agreement and this Agreement, and any
other action reasonably requested by Parent in furtherance thereof; (b) against
any action or agreement that would result in a breach of any covenant,
representation or warranty or any other obligation or agreement of the Company
contained in the Merger Agreement or of Stockholder contained in this Agreement;
and (c) against any Acquisition Proposal made by any person other than Parent or
any of its affiliates. Stockholder hereby agrees that it will not enter into any

proxy or power of attorney with respect to the Shares prior to the Termination
Date (other than a proxy or power of attorney to an officer of the Company that
may be exercised solely in accordance with this Section 3 and except as provided
in Section 4 below) or vote or give instructions in any manner inconsistent with
clause (a), (b) or (c) of the preceding sentence. Stockholder hereby agrees,
during the period commencing on the date hereof and ending on the Termination
Date, not to, and, if applicable, not to permit any of Stockholder's affiliates
to, vote or execute any written consent in lieu of a stockholders meeting or
vote, if such consent or vote by the stockholders of the Company would be
inconsistent with or frustrate the purposes of the other covenants of
Stockholder pursuant to this paragraph. As used in this Agreement, "person"
shall have the meaning specified in Sections 3(a)(9) and 13(d)(3) of the
Exchange Act.

     (e) The execution and delivery of this Agreement by Stockholder do not, and

preventing or disabling Stockholder from performing its obligations under this
Agreement.

with respect to Parent and its affiliates, that Stockholder shall not, and shall
not permit any affiliates or, if applicable, any director, officer, employee

respect to any matter described in Section 7(a) hereof or any Acquisition
Proposal or (ii) participate in any negotiations concerning, or provide to any
other person any information or data relating to the Company or any of its
Subsidiaries for the purpose of, or have any discussions with any person
relating to, or cooperate with or assist or participate in, or facilitate, any
inquiries or the making of any proposal which constitutes, or would reasonably
be expected to lead to, any effort or attempt by any other person to seek to
effect any matter described in Section 7(a) hereof or any Acquisition Proposal,
or agree to or endorse any Acquisition Proposal, or otherwise facilitate any
effort or attempt to make or implement such an Acquisition Proposal. Stockholder
agrees immediately to cease and cause to be terminated any existing activities,
discussions or negotiations with any persons conducted heretofore by Stockholder
with respect to any possible Acquisition Proposal, or any matter described in
Section 7(a) hereof, and will take the necessary steps to inform Stockholder's
Representatives of the obligations undertaken by Stockholder with respect to
Stockholder's Representatives in this Section 7; provided, that nothing in this
Agreement shall restrict Frank J. A. Cilluffo in the exercise of his fiduciary
duties to stockholders of the Company, in his capacity as a director of the
Company, under applicable law or otherwise prohibit him from taking such
actions, in his capacity as a director of the Company, as may be permitted
(under the circumstances therein specified) pursuant to Section 5.2 of the
Merger Agreement.

     (c) Stockholder hereby agrees, while this Agreement is in effect, to notify
Parent promptly of the number of any additional shares of Company Common Stock
and the number and type of any other Shares acquired by Stockholder, if any,
after the date hereof.

     8. Further Assurances. From time to time, at the other party's request and
without further consideration, each party hereto shall execute and deliver such
additional documents and take all such further action as may be necessary or
desirable to consummate and make effective, in the most expeditious manner
practicable, the transactions contemplated by this Agreement. Without limiting
the generality of the foregoing, none of the parties hereto shall enter into an
agreement or arrangement (or alter, amend or terminate any existing agreement or
arrangement) if such action would materially impair the ability of such party to
effectuate, carry out or comply with all the terms of this Agreement.

     9. Survival. None of the representations, warranties, covenants and
agreements of the parties herein shall survive beyond the Termination Date.

     10. Notices. All notices and other communications hereunder shall be in
writing and shall be deemed duly given if given in the manner set forth in
Section 9.2 of the Merger Agreement. All notices hereunder shall be given to a
party at his or its address stated on the signature pages of this Agreement or
at its address set forth in Section 9.2 of the Merger Agreement or at any other
address as the party may specify for this purpose by notice to the other parties
pursuant to this Section 10.

     11. No Waivers. No failure or delay by Parent or Sub in exercising any
right, power or privilege under any Support Document shall operate as a waiver
of that right, power or privilege. A single or partial exercise of any right,
power or privilege shall not preclude any other or further exercise of that
right, power or privilege or the exercise of any other right, power or

                                      -6-

<PAGE>

privilege. The rights and remedies provided in the Support Documents shall be
cumulative and not exclusive of any rights or remedies provided by law.

     12. Amendments, Etc. No amendment, modification, termination or waiver of
any provision of any Support Document, and no consent to any departure by
Stockholder or Parent or Sub from any provision of any Support Document, shall
be effective unless it shall be in writing and signed and delivered by each
party hereto, and then it shall be effective only in the specific instance and
for the specific purpose for which it is given.

     13. Successors and Assigns; Third Party Beneficiaries.

     (a) No party shall assign any of such party's rights or remedies or
delegate any of such party's obligations or liabilities, in whole or in part,
under any Support Document, except that Parent or Sub may assign all or any of
its rights hereunder to any affiliate of Parent or Sub. Any assignment or
delegation in contravention of this Section 13 shall be void ab initio and shall
not relieve the assigning or delegating party of any obligation under any
Support Document.

     (b) The provisions of each Support Document shall be binding upon and inure
solely to the benefit of the parties hereto and their respective permitted
heirs, executors, legal representatives, successors and assigns, and no other
person.

     14. Governing Law; Submission to Jurisdiction. This Agreement and each
other Support Document and all rights, remedies, liabilities, powers and duties
of the parties hereto and thereto, shall be governed by and construed in
accordance with the laws of the State of Delaware applicable to contracts
executed in and to be performed entirely within that State. Parent, Sub and each
Stockholder hereby (w) submit to the non-exclusive jurisdiction of any State and
Federal courts sitting in Delaware with respect to matters arising out of or
relating hereto, (x) agree that all claims with respect to such matters may be
heard and determined in an action or proceeding in such Delaware State or
Federal court, and (y) agree that a final judgment in any such action or
proceeding will be conclusive and may be enforced in other jurisdictions by suit
on the judgment or in any other manner provided by law.

     15. Severability of Provisions. If any term or other provision of any
Support Document is invalid, illegal or incapable of being enforced by any law
or public policy, all other terms and provisions of such Support Document shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify such Support Document so as to effect the
original intent of the parties as closely as possible in an acceptable manner in
order that the transactions contemplated hereby are consummated as originally
contemplated to the greatest extent possible.

otherwise requires, be used in the singular or the plural, depending on the
reference. The use in this Agreement of the word "include" or "including," when
following any general statement, term or matter, shall not be construed to limit
such statement, term or matter to the specific items or matters set forth
immediately following such word or to similar items or matters, whether or not
nonlimiting language (such as "without limitation" or "but not limited to" or
words of similar import) is used with reference thereto, but rather shall be
deemed to refer to all other items or matters that fall within the broadest
possible scope of such general statement, term or matter.

the entire agreement and understanding of each of the parties hereto, and

respect to the subject matter of the Support Documents.

     18. Enforcement. The parties agree that irreparable damage would occur in
the event that any of the provisions of any Support Document were not performed
in accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of the Support Documents and to enforce
specifically the terms and provisions of any Support Document in any Federal
court sitting in the State of Delaware or State of Delaware court, this being in
addition to any other remedy to which they are entitled at law or in equity.

representations, warranties, covenants and agreements set forth herein and in
the Merger Agreement, and intending to be legally bound hereby, Parent, Sub and
Stockholder agree as follows:

     1. Defined Terms. Terms used herein without definition shall have the
meanings assigned to such terms in the Merger Agreement.

     2. Agreement to Tender. Stockholder hereby agrees to validly tender, or
cause the record owner to validly tender, all of the Tender Shares pursuant to

with any written consent of the stockholders of the Company, Stockholder shall

Voting Shares to be counted as present thereat for purposes of establishing a
quorum, and Stockholder shall vote (or cause to be voted) or act by written
consent with respect to all of the Voting Shares that are beneficially owned by
him or as to which he has, directly or indirectly, the right to vote or direct

during the period commencing on the date hereof and ending on the Termination
Date, not to, and, if applicable, not to permit any of his affiliates to, vote

Representatives in this Section 7; provided, that nothing in this Agreement

without further consideration, each party hereto shall execute and deliver such
additional documents and take all such further action as may be necessary or
desirable to consummate and make effective, in the most expeditious manner
practicable, the transactions contemplated by this Agreement. Without limiting
the generality of the foregoing, none of the parties hereto shall enter into an
agreement or arrangement (or alter, amend or terminate any existing agreement or
arrangement) if such action would materially impair the ability of such party to

agreements of the parties herein shall survive beyond the Termination Date.

     10. Notices. All notices and other communications hereunder shall be in

right, power or privilege under any Support Document shall operate as a waiver
of that right, power or privilege. A single or partial exercise of any right,

right, power or privilege or the exercise of any other right, power or
privilege. The rights and remedies provided in the Support Documents shall be
cumulative and not exclusive of any rights or remedies provided by law.

     12. Amendments, Etc. No amendment, modification, termination or waiver of
any provision of any Support Document, and no consent to any departure by

party hereto, and then it shall be effective only in the specific instance and
for the specific purpose for which it is given.

     13. Successors and Assigns; Third Party Beneficiaries.

     (a) No party shall assign any of such party's rights or remedies or
delegate any of such party's obligations or liabilities, in whole or in part,
under any Support Document, except that Parent or Sub may assign all or any of
its rights hereunder to any affiliate of Parent or Sub. Any assignment or
delegation in contravention of this Section 13 shall be void ab initio and shall
not relieve the assigning or delegating party of any obligation under any
Support Document.

     (b) The provisions of each Support Document shall be binding upon and inure
solely to the benefit of the parties hereto and their respective permitted
heirs, executors, legal representatives, successors and assigns, and no other
person.

     14. Governing Law; Submission to Jurisdiction. This Agreement and each
other Support Document and all rights, remedies, liabilities, powers and duties
of the parties hereto and thereto, shall be governed by and construed in
accordance with the laws of the State of Delaware applicable to contracts
executed in and to be performed entirely within that State. Parent, Sub and each
Stockholder hereby (w) submit to the jurisdiction of any State and Federal
courts sitting in Delaware with respect to matters arising out of or relating
hereto, (x) agree that all claims with respect to such matters may be heard and
determined in an action or proceeding in such Delaware State or Federal court,
and (y) agree that a final judgment in any such action or proceeding will be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law.

     15. Severability of Provisions. If any term or other provision of any
Support Document is invalid, illegal or incapable of being enforced by any law
or public policy, all other terms and provisions of such Support Document shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify such Support Document so as to effect the
original intent of the parties as closely as possible in an acceptable manner in
order that the transactions contemplated hereby are consummated as originally
contemplated to the greatest extent possible.

     16. Headings and References. Article and Section headings in any Support
Document are included for convenience of reference only and do not constitute a
part of the Support Document for any other purpose. References to Articles and
Sections in any Support Document are references to the Articles and Sections of
the Support Document unless the context shall require otherwise. Any of the
terms defined in this Agreement may, unless the context otherwise requires, be
used in the singular or the plural, depending on the reference. The use in this
Agreement of the word "include" or "including," when following any general
statement, term or matter, shall not be construed to limit such statement, term
or matter to the specific items or matters set forth immediately following such
word or to similar items or matters, whether or not nonlimiting language (such
as "without limitation" or "but not limited to" or words of similar import) is
used with reference thereto, but rather shall be deemed to refer to all other
items or matters that fall within the broadest possible scope of such general
statement, term or matter.
