I  will offer the following consulting services and support for Erex as it moved

Erex  and  assist  it  and  its  representatives  with  the  following  issues:

     1.   I  will assist Erex in designing its network architecture for wireless
          data  flow  to and from mobile Dragonfly units to Erex hosted back-end
          or  customer  centric  systems  as  required.

     2.   I  will  assist  in  designing  and recommending complete "end-to-end"
          solutions  where:

          i)   Erex  fully  hosts  the  connectivity  and  back-end  systems for
               Dragonfly  connectivity  and  document  transfer.

               back-end  system.

          iii) Erex  provides  Dragonfly  units  and  either  sells  or provides
               recommendations  on  software  that  allows  customers  to  host
               in-house  systems  for  data  transfer.

     3.   I  will  provide  recommendations  on  methods  for  data  transfer of
          documents and/or filed from the Dragonfly units to back-end systems as
          required.

          "end-to-end"  solutions  for each of the transmission scenarios above.
          This  will  include  mobile software, as well as any required backend,
          middleware,  transaction,  and  portal  server  software.

     5.   I  will  assist Erex by recommending a Security Infrastructure for its
          network, as well as security options for secure data transmission from
          the  Dragonfly.
