Dear  Carl:

This  is  an agreement where under I will offer technical consulting services to
E-Rex,  Inc.  (referred  to  herein  as  Erex).

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

     A.     I will act as a Senior Technology and Network Systems Consultant for
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.

          ii)  Erex  hosts  a  wireless gateway to the Internet and a customer's
               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.


     4.   I  will  assist  in  and  recommend  software  required  to create the
          "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.


     6.   I  will  assist Erex in choosing the necessary hardware infrastructure
          components  and  suitable  configurations  for  the  Dragonfly.



     7.   I  will  assist  Erex  in  providing  technical  explanations  to  its
          customers  and investors regarding the potential uses of the Dragonfly
          and  the  Erex  network  as  required.

In  return  for the above services, E-Rex Inc. will pay to me my standard fee of
$5,000  U.S. per month.  E-Rex Inc. also agrees to cover any reasonable, actual,
out-of-pocket  operating  expenses  supported  by  proper documentation, such as

duration  of  6  months,  renewable upon mutual agreement by both parties.  I am
