agree as follows:

      1. SERVICES. During the term of this Agreement, MEGASYSTEMS agrees to act
as the sales agent for HEARTSOFT for all retail distribution of the HEARTSOFT

acknowledged by both parties that MEGASYSTEMS shall not act as the sales agent
for Safari within the educational or curriculum marketplaces.

      2. TERM. This Agreement shall be for a term of one (1) year, commencing on
July 15, 2001 and ending on July 14, 2002, unless sooner terminated in
accordance with the provisions of this Agreement. Provided that neither

primary point of contact with its network of retailers, distributors,
representatives and agents (the "retail distribution network"). This would
include (but not be limited to) such activities as:

      a) Distribution of samples and sales literature
      b) Basic product education
      c) Coordination of special sales promotions (all jointly approved with
         HEARTSOFT)
      d) Accumulation and distribution of sales figures, whenever available
      e) Obtaining approval from HEARTSOFT for any "other expenses" (noted in
         Section 8 of Agreement) prior to incurring such expenses, examples
         being rebate programs, marketing development funds, and promotional
         items.

      3.1   MEGASYSTEMS shall accept primary responsibility for the processing
            of orders received from its retail distribution network. MEGASYSTEMS
            agrees that all orders for Safari are subject to acceptance or
            rejection by HEARTSOFT. Accordingly, MEGASYSTEMS is hereby granted
            only the authority to solicit orders for Safari, and has neither
            expressed or implied authority to accept any order on behalf of
            HEARTSOFT, or to enter into any written or oral contract or
            agreement of any nature on behalf of HEARTSOFT, unless so authorized
            in writing by HEARTSOFT.

            invoices to and coordinating payment from the retail distribution

            returns, although any shipping expense for returned product shall be
            the responsibility of HEARTSOFT. The goal of these activities is to
            provide, whenever practical, a single point-of-contact for the
            retail distribution network. MEGASYSTEMS agrees that any product in
            resalable condition will be returned to HEARTSOFT and that when

           literature, and by coordinating input to the sales literature from
           the retail distribution network.

      4.3  As the manufacturer of Safari, HEARTSOFT recognizes and accepts the
           fact that it may, from time to time, be called upon by MEGASYSTEMS to
           assist MEGASYSTEMS in the execution of its duties. HEARTSOFT agrees
           to assist MEGASYSTEMS on a reasonable basis.

                                                                     Page 2 of 6

other expenses that have been PRE-APPROVED by HEARTSOFT. See attached Exhibit A
for current understanding of pricing, calculation of invoice, MEGASYSTEMS
collection of an invoice and deduction of fees and expenses when remitting
payment to HEARTSOFT. MEGASYSTEMS agrees to provide reasonable audit access to
any relevant portion of its bookkeeping to HEARTSOFT for verification and
validation.

      9. REPORTING. MEGASYSTEMS routinely receives on a monthly basis a
collection of reports from the retail distribution network that reflect "sell
to" and "sell through" for certain retail channels. MEGASYSTEMS shall endeavor
to forward to HEARTSOFT such information from these reports that relates to
Safari within seven (7) business days of receipt by MEGASYSTEMS. Although it
cannot guarantee the accuracy or completeness of these reports, MEGASYSTEMS will
