7, 2000, the Company was acquired by Stamps.com and is now a wholly owned
subsidiary of Stamps.com (the "Acquisition");
                               -----------   

     WHEREAS, under the terms of the Agreement, the Company provides MBE and MBE

     WHEREAS, in connection with the services under the Agreement, the Company

     WHEREAS, the parties desire to modify the fee and exclusivity arrangements

                                                                     ---------

     1.  AMENDMENT TO THE AGREEMENT

         a.  Section 3(d)(iii) of the Agreement is hereby amended and restated
in its entirety to read as follows:

               "(iii)  The Company may, at its option, terminate the exclusivity
         provisions set forth in this Section 3(d) upon the occurrence of any of
         the following events: (A) if MBE and all MBE Centers together fail to
         ship at least [***]* packages manifested by the Service in any period
                        ---                                                     
         of three (3) full months, with measurement commencing on January 1,
         2001 (other than any such failure which is directly caused by an event
         of force majeure (as set forth in Section 18(e)) or by the failure of
         the Service to operate in accordance with the Specifications or by the
         Company's breach of any of its obligations hereunder); or (B) MBE
         ceases to own at least 490,000 shares of common stock of Stamps.com,
         including shares that MBE has the right to acquire under the Warrant
         (all as adjusted for any stock split, stock dividend, recapitalization
         or similar transaction). For purposes of this Section 3(d)(iii), MBE
         shall be deemed to own Stamps.com shares pledged as collateral to
         secure bank loans to MBE or to MBE's corporate parent. Stamps.com
         understands that all such shares and the Warrant are currently so
         pledged."

          b.  Section 8(a) of the Agreement is hereby amended by redesignating
the existing text (following the heading "Basic Fee") as subsection (i) and by
adding the following text to the end of the existing text:

          "Through December 31, 2000, the Company shall deem the payment by MBE
          of the "Service Fee" (as defined in subsection (ii) below) to be made
          in satisfaction of, and in substitution for, the Basic Fee, and the
          Company agrees that it shall not be entitled to receive (and shall not
          seek to collect) the Basic Fee during the "Service Fee Period" (as
          defined in subsection (ii) below), as and to the extent the Service
          Fee is paid."

          c.  A new subsection (ii) shall be added to Section 8(a) of the 
Agreement, to read in its entirety as follows:

               "(ii)  In consideration for the Service provided hereunder and
          the other obligations of the Company hereunder, the Company shall be
          entitled to receive from MBE a fixed monthly service fee of $500,000
          (the "Service Fee") for the period of time commencing on the Amendment
          Date and ending on December 31, 2000 (the "Service Fee Period").  Such
          Service Fee will be due and payable without regard to the volume of
          packages shipped utilizing the Service and is in satisfaction of, and
          in substitution for, the Basic Fee during the Service Fee Period.
          Payment of the Service Fee shall be due and payable on or before the
          20th day of each month during the Service Fee Period (i.e., March 20,
          April 20, etc.).  MBE's obligations under this subsection (ii) shall
          be secured by the

          Warrant, and, in the event that after any exercise of the Warrant the
          value of the unexercised portion of the Warrant ("Warrant Value") is

          Service Fees payable over the course of the Service Fee Period, then
          MBE shall prepay that portion of the then-unpaid balance of such
          Service Fee by an amount sufficient to reduce such then-unpaid balance
          to an amount that is equal to or less than the Warrant Value."
