Dear Kirk:

We are very excited about welcoming you to the Pivotal  Corporation  ("Pivotal")
team.   This  letter  sets  forth  the  terms  of  your  employment  with  Simba
Technologies Inc. ("Simba"), as a subsidiary of Pivotal,  subject to closing the
acquisition by Pivotal of all of the issued and outstanding shares of Simba (the
"Acquisition").  We are  pleased  to offer you  employment  under the  following
terms:

1.   Your position will be Vice President,  Advanced  Technology and Deputy CTO,
     to be located in Vancouver. You will report to the Chief Technical Officer.

2.   Your salary will be C$150,000 per year, payable semi-monthly.

3.   Your annual  vacation  entitlement  will be in accordance  with the Pivotal
     vacation policy.  Details of this policy are available from Human Resources
     for you to review.  Simba holiday  schedules  will apply until such time as
     the holiday schedule is incorporated into the Pivotal holiday schedule. Any
     other accrued paid time off at Simba does not carry over or get paid out.

4.   As a  condition  of  employment,  you are  eligible to  participate  in the
     Pivotal  employee  benefits plan,  which has been  established  for Pivotal
     employees based in Canada. You will, however,  remain on the Simba employee
     benefits  plan until such time as the Simba plan is  incorporated  into the
     Pivotal plan.  Details of the Pivotal employee  benefits plan are available
     from Human Resources for you to review.

5.   As a Pivotal  employee,  you will be eligible to  participate  in Pivotal's
     Employee  Stock  Purchase  Program  (the  "ESPP").  This  program  entitles
     employees to purchase Pivotal stock via payroll deduction at a 15% discount
     to the  market  price  based on  terms  of the  ESPP.  To be  eligible  for
     participation  in the ESPP, you must be a permanent  employee on payroll at
     the  commencement of one of two ESPP offering  periods;  either January 1 -
     June 30 or July 1 - December  31.  Details of the ESPP are  available  from
     Human  Resources.  This paragraph sets forth only a general  summary of the
     ESPP and is subject to  modification  at the  discretion  of Pivotal.  ESPP
     documents and applicable law are controlling and govern.

6.   Your  employment  will  commence on or about June 16, 2000.  You  authorize
     Pivotal to obtain your Simba employment  records.  Any medical  information
     contained  therein will be kept  confidential in accordance with applicable
     law.

7.   The terms and conditions of your currently  unvested Simba options  ("Simba
     Options") will be changed as follows:

     o    The number of Pivotal  options you will receive will be  calculated by
          dividing the number of your Simba options by an exchange ratio of 13;

     o    The  exercise  price of the Pivotal  options you will  receive will be
          calculated by multiplying  the exercise price of your Simba options by
          an exchange ratio of 13;

     o    Your vesting schedule will not change; and,

     o    All other terms and conditions  will be in accordance with the Pivotal
          stock option plan, a summary of which is available for your review.

8.   As a condition of your employment, you are required to sign an agreement of
     confidentiality  and  acknowledge  that the  intellectual  property,  which
     results from your employment, is owned by Pivotal. In addition, should your
     employment by Pivotal terminate for any reason, the agreement prohibits you
     from interfering with the employees,  customers or business of Pivotal,  or
     competing with Pivotal for a period of 6 months  following the cessation of
     employment.

This offer of employment is open for your acceptance until the close of business
Monday,  June 12,  2000.  Please sign the  attached  copy of this letter and the
Employee  Confidentiality  Agreement to indicate your agreement,  and return the
signed copies to Dave Pritchard.

This agreement supersedes any prior oral or written  understandings  between you
and Simba  Technologies Inc. and/or Pivotal,  with the sole exception being that
the rights to your unvested stock options earned prior to the  Acquisition  will
not be  extinguished  or altered by your  acceptance  of this  offer,  except as
otherwise specifically agreed to by you.

We look forward to you joining us in our quest to build a major Internet company
that dominates the growing business-to-business  marketspace. We look forward to
a long and mutually rewarding relationship.


Yours very truly,
                                    I agree with and accept the
                                    above terms and  conditions of employment.
