                                  -------------

                                  CONFIDENTIAL



                                    CONTRACT

              ESYON CORPORATION - WORLWIDE WIRELESS NETWORKS, INC.

                        ________________________________


THIS CONTRACT SUMMARIZES THE PRINCIPAL TERMS OF A FORMAL AGREEMENT ("AGREEMENT")
TO  BE  PREPARED  BETWEEN  ESYON  CORPORATION  ("ESYON")  AND WORLDWIDE WIRELESS
NETWORKS,  INC.  ("WWWN"),  BOTH  NEVADA  CORPORATIONS.


1.   Share  Exchange

     a.   WWWN  will  exchange  3,000,000  of  WWWN's  outstanding  shares
          (unrestricted)  for  shares  to  ESYON.

     b.   ESYON  will  exchange  500,000  of  ESYON's  outstanding  shares
          (unrestricted)  for  shares  to  WWWN.

2.   Company  Promissory  Notes

     Concurrent  with  the  signing  of  formal  contract and the aforementioned
     exchange  of  stock,  ESYON  is  to  advance  an  initial $100,000 to WWWN.

     a.   ESYON  will  also  provide  WWWN  with  future  working  capital  cash
          infusions  as  approved by the Board of Directors ("BOD") of ESYON and
          the  newly  constituted  BOD of WWWN, as noted in Paragraph 4, herein.
          WWWN  has  forecast its cash infusion needs under different scenarios,
          which  range  up  to  $150,000 per month for six months or more, until
          break-even  occurs. Notwithstanding board decisions, ESYON's financial
          commitment  to  WWWN  is  one  million  dollars.

     b.   All  funds provided by ESYON to WWWN will be in the form of Promissory
          Notes  bearing  interest  at  10%,  paid  annually.  Funds  will  be
          collateralized  with  WWWN  network  assets  and  liens  filed.  Total
          collateralization  will  not  exceed  one  million  dollars.

     c.   In  the  event  that  an  existing  or  unforeseen lawsuit causes dire
          financial  distress to WWWN or current creditors call for an immediate
          payment of debts owed them by WWWN that causes dire financial distress
          to  WWWN, ESYON may elect to convert its Promissory Notes and purchase
          the  identified  assets as specified in Paragraph 2(b), above, for the
          value  of  all  loans  provided  to  date.


<PAGE>
     d.   ESYON  also  has  the option to convert its collective Promissory Note
          into  WWWN  shares  at  25%  below market price (basis being the 5-day
          average  closing price prior to conversion date). It is ESYON's intent
          to  convert the 10% interest portion of said notes into equity, but it
          is  not  obligated  to  do  so.

3.   Concurrent  with  the  signing  of  this contract ESYON advancing the first
     $100,000,  the  WWWN Board of Directors ("BOD") will elect one new director
     to  the  Board  of Directors as nominated by ESYON, and BOD in the meantime
     also  accept  the  resignation  of  Tom  Rotert  from the BOD. The BOD will
     immediately  elect  a  second  new  director  as  nominated  by  ESYON.

4.   It  is understood by all parties that ESYON is not responsible for assuming
     or  paying  down any of WWWN's liens or debt of approximately $5.5 million,
     and  that  all remedies to significantly reduce or eliminate this debt will
     be  taken  into  consideration,  and  a course of action will be set by the
     newly  constituted  BOD  of  WWWN  as  soon as possible to accomplish this.

5.   Both  parties  acknowledge that this contract is a legally binding document
     and  that  it  has  been  reviewed  by  their  respective  attorneys.

AGREED  TO  ON  THIS  28th  DAY  OF  DECEMBER,  2000.
