     o    All other terms and conditions  will be in accordance with the Pivotal

not be  extinguished  or altered by your  acceptance  of this  offer,  except as
otherwise specifically agreed to by you.

that dominates the growing business-to-business  marketspace. We look forward to
a long and mutually rewarding relationship.

                                    I agree with and accept the
                                    above terms and  conditions of employment.
