                              E-STAMP CORPORATION

                     CHANGE OF CONTROL SEVERANCE AGREEMENT

     This Change of Control Severance Agreement (the "Agreement") is made and
entered into effective as of November 17, 2000 (the "Effective Date"), by and
between Roderick Witmond (the "Employee") and E-Stamp Corporation, a Delaware
corporation (the "Company").  Certain capitalized terms used in this Agreement
are defined in Section 1 below.

                                R E C I T A L S
                                ---------------

     A.  The Company may from time to time consider the possibility of a Change
of Control.  The Board of Directors of the Company (the "Board") recognizes that
such consideration can be a distraction to the Employee and can cause the
Employee to consider alternative employment opportunities.

     B.  The Board believes that it is in the best interests of the Company and
its shareholders to provide the Employee with an incentive to continue his or
her employment and to maximize the value of the Company upon a Change of Control
for the benefit of its shareholders.

     C.  In order to provide the Employee with enhanced financial security and
sufficient encouragement to remain with the Company notwithstanding the
possibility of a Change of Control, the Board believes that it is imperative to
provide the Employee with certain severance benefits upon the Employee's
termination of employment following a Change of Control.

                                   AGREEMENT
                                   ---------

     In consideration of the mutual covenants herein contained and the continued

or nolo contendere to, a felony, and (iii) Employee's willful and continued
