                    RESIGNATION AND MUTUAL RELEASE AGREEMENT


         This Resignation and Mutual Release Agreement (the "Agreement") is made
by and between Interlink Computer Sciences,  Inc., a California corporation (the
"Company") and Gloria M. Purdy ("Purdy").

         WHEREAS, Purdy has been employed by the Company;

         WHEREAS,  in  connection  with  Purdy's  resignation  as an officer and
director of the Company,  Purdy and the Company have mutually agreed to continue
Purdy's relationship with the Company as a consultant through June 30, 1998;

         NOW,  THEREFORE,  in  consideration of the mutual promises made herein,
Purdy and the Company  (collectively  referred to as the "Parties") hereby agree
as follows;


         1. Resignations.  Purdy  hereby  resigns as of  December  31, 1997 (the
"Effective Date") as a director and an officer of the Company, and as a director
and officer of any of the Company's subsidiaries.

         2. Consultant  Duties.  During the  Consulting  Period  (as  defined in
Section 3  below),  Purdy  will  continue  to work on  behalf  of the  Company's
interest as a Consultant. The duties and responsibilities of Purdy shall include
the duties and  responsibilities  as determined by mutual agreement  between the
Company and Purdy.  Purdy shall perform  faithfully  all duties  assigned to her
during the Consulting Period to the best of her ability.

         3. Expiration.

                  (a) The Consulting  Period shall begin upon the Effective Date
and  shall  expire  at 5:00  p.m.,  California  time,  on  June  30,  1998  (the
"Expiration  Date") unless sooner terminated  pursuant to the provisions of this
Agreement.  The period  from the  Effective  Date until the  Expiration  Date is
referred to herein as the "Consulting Period".

                  (b) Early  Termination.  The  Company  may  terminate  Purdy's
consulting  agreement  for Cause (as defined in Section 3(d)) at any time during
the Consulting Period.

                  (c) Death.  The  Company  shall have no  obligation  to pay or
provide any  compensation or benefits under this Agreement on account of Purdy's
death.  Purdy's  rights  under the benefit  plans of the Company in the event of
Purdy's  death  prior to the  Expiration  Date  shall be  determined  under  the
provisions of those plans.

                  (d) Cause.  For all  purposes  under this  Agreement,  "Cause"
shall mean (i) willful failure by Purdy to perform her duties hereunder,  (ii) a
willful act by Purdy which  constitutes  gross misconduct and which is injurious
to the Company,  (iii) a willful breach by Purdy of a material provision of this
Agreement,  (iv) a material  violation  of a federal,  state,  or foreign law or
regulation  applicable to the business of the Company.  No act or failure to act
by Purdy shall be  considered  "willful"  unless  committed  without  good faith
without a reasonable  belief that the act or omission was in the Company's  best
interest.

         4. Vesting Under Stock Option Agreement.  The parties  acknowledge that
the vesting of the stock options previously granted to Purdy under the Company's
stock  plans will  continue  to the extent the options  would  otherwise  become
exercisable  through  the  conclusion  of  Purdy's  consulting   agreement.   In
accordance  with the  terms of such  options,  Purdy  shall  have  until 30 days
following  termination of her consulting  agreement (June 30, 1998 or for Cause)
to exercise the vested  portions  thereof.  There shall be no further vesting of
any stock options  previously  granted to Purdy under the Company's  stock plans
following  termination of her  consulting  agreement.  If the Company  re-prices
employee stock options during Purdy's consulting period,  Purdy will be eligible
to  participate  in the repricing  according to the same terms and conditions as
the Company's employees.

         5. Severance  Payment.  The Company agrees to pay Purdy severance equal
to 6 months of her current base salary of $14,166.67 per month  ("Severance") in
a lump sum payable on the  Company's  January 15th payroll run. The Company also
agrees to pay Purdy all unused,  accrued vacation pay as of December 31, 1997 on
the Company's January 15, 1998 payroll run.  Furthermore,  the Company agrees to
pay Purdy her Q2, FY98 bonus of $17,000  (USD) on the  January 15, 1998  payroll
run. The parties  understand and agree that the Severance will be reduced by all
necessary and  appropriate  taxes (e.g.,  payroll,  withholding  for Federal and
State taxes, FICA, etc.) which the Company has the obligation of retaining.

         6.  Benefits.  Following  the  Employment  Period,  the  Company  shall
continue  to make  coverage  available  to Purdy  and her  dependents  under the
Company's group health and dental plans through COBRA.

         7. Confidential Information.  Purdy agrees to immediately return to the
Company  all  of  the  Company's   property  and  confidential  and  proprietary
information  in her  possession as of the  termination  of her  employment,  and
agrees not to use or disclose  any such  information  without the prior  written
consent of the  Company.  The  limitations  described  in this  Section 7 are in
addition to any  similar  limitations  to which Purdy is subject  based on other
legal or contractual obligations.

         8. Insider Trading. During the Consulting Period, Purdy and the Company
agree that Purdy shall be subject to the  restrictions  and  obligations  of the
Company's  Insider Trading Policy, as amended from time to time, a copy of which
is in Purdy's possession.

         9. California Labor Code.  Assuming the payments of the above severance
amounts,  California  Labor Code  section  206.5 will not be  applicable  to the
parties hereto. Said section provides in pertinent part:

                                   55

<PAGE>

            NO EMPLOYER  SHALL  REQUIRE THE  EXECUTION OF ANY RELEASE OF
            ANY CLAIM OR RIGHT ON  ACCOUNT  OF WAGES  DUE,  OR TO BECOME
            DUE,  OR MADE AS AN ADVANCE  ON WAGES TO BE  EARNED,  UNLESS
            PAYMENT OF SUCH WAGES HAS BEEN MADE.

         10.  Release of Claims.  Purdy agrees that the foregoing  consideration
represents  settlement in full of all outstanding  obligations  owed to Purdy by
the Company. The Company and Purdy, on behalf of themselves and their respective
heirs,  executors,  officers,  directors,  employees,  investors,  shareholders,
administrators,  predecessor  and successor  corporations,  and assigns,  hereby
fully and forever  release  each other and their  respective  heirs,  executors,
officers,  directors,   employees,  investors,   shareholders,   administrators,
predecessor  and  successor  corporations,  and assigns,  of and from any claim,
duty, obligation or cause of action relating to any matters of any kind, whether
presently  known or  unknown,  suspected  or  unsuspected,  that any of them may
possess  arising from any omissions,  acts or facts that have occurred up to and
including the Effective Date including, without limitation:

breach of  contract,  both  express and implied  breach of the  covenant of good
faith and fair  dealing,  both  express and implied;  negligent  or  intentional
infliction of emotional  distress;  negligent or intentional  misrepresentation;
negligent or  intentional  interference  with contract or  prospective  economic

regulations relating to employment or employment discrimination; and

                  (e) any and all claims for attorneys' fees and costs.

         The Company and Purdy agree that the release set forth in this  section

the provisions of California Civil Code Section 1542 which provides as follows:

            A  GENERAL  RELEASE  DOES NOT  EXTEND  TO  CLAIMS  WHICH THE
            CREDITOR  DOES NOT KNOW OR  SUSPECT TO EXIST IN HER FAVOR AT
            THE TIME OF  EXECUTING  THE  RELEASE,  WHICH IF KNOWN BY HER

directly  or  indirectly,  relating  to such  parties,  Purdy  will  refer  such
inquiries to the Company's Chief Financial Officer.

         15.   Indemnification.   The   Company   agrees   to   extend   Purdy's
indemnification  agreement  through the length of her consulting  assignment and
that nothing in this Agreement  will affect  Purdy's  rights to  indemnification

Incorporation  or Bylaws (NOTE:  Subject to final Board approval on December 18,
