          JDE  environments  (test and production)  onto hardware  separate from
          Audiovox's  hardware.  The Purchaser's JDE environments  shall provide
          the same  functionality  and level of service as ACC was getting as of
          the time just prior to Closing and shall also be  integrated  with the
          back-end  Webstore  that  Audiovox  will continue to use. The hardware
          brand and configuration used will be mutually agreed upon by Purchaser
          and Seller in good faith prior to implementation.

     b.   Within ninety days of Closing, Audiovox shall separate out Purchaser's
          Lotus Notes  email  environment  from  Audiovox's  environment  onto a
          separate server for Purchaser so that  Purchaser's  email  environment
          can be operated and managed independently.

     c.   Within  ninety  days  of  Closing,  Audiovox  shall  separate  out the
          DNS/DHCP  Services  for  Purchaser  onto a  separate  server  so  that
          Purchaser's network can be independent of Audiovox's network.

          Wireless Products accessories  transaction sales that come through the
          webpages to the webstore.

     e.   Purchaser  shall  not be  obligated  to make  any  other  payments  to
          Audiovox or Seller with respect to completion of the work set forth in
          (a) -(d)  (including  any expenses  incurred by Audiovox or Seller for

performed in that State. All disputes arising out of this letter agreement shall
be resolved in accordance with Section 10.09 of the Purchase Agreement.
