29th  day  of  March  2000  by  and  between  BroadBand  Wireless  International
Corporation,  a  Nevada  corporation  ("BBAN"),  and  iTELL,  Inc.,  a  Maryland
corporation  ("iTELL")  (BBAN and iTELL may be  collectively  referred to as the
"Parties").

                                    Premises

     A. On March 1, 2000,  BBAN and iTELL  executed a Letter of  Agreement  (the
"Agreement"), pursuant to which iTELL became a wholly owned subsidiary of BBAN.

     B. The  consideration  provided in the  Agreement was $200,000 cash and Two
Million (2,000,000) shares of BBAN's common stock ("Purchase Price").

     C. In  addition  to the  Purchase  Price,  BBAN  agreed to assist  iTELL in
securing financing for its operations ("Financing Obligation").

     NOW,  THEREFORE,  based on the foregoing  premises,  which are incorporated
herein by reference,  and for and in  consideration  of the mutual covenants and
agreements  contained  herein,  and  in  reliance  on  the  representations  and
warranties set forth in this Addendum, the benefits to be derived herein and for
other  valuable  consideration,  the  sufficiency  of which is hereby  expressly
acknowledged, the Parties agree as follows:

          1. Financing.  BBAN agrees to assist in securing financing for iTELL's
     operations.  BBAN  agrees to provide  Two  Million  Five  Hundred  Thousand
     (2,500,000)  shares of its common  stock  ("Financing  Shares")  for use as
     collateral in securing iTELL's financing.

          2. Restricted  Stock.  iTELL  acknowledges  and agrees that all of the
     Financing  Shares  issued  hereunder,  as well  as all  shares  issued,  or
     issuable  pursuant  to  the  Agreement,   shall  bear  a  prominent  legend
     restricting  the sale or other  transfer  thereof  unless  such  shares are
     registered with the United State  Securities and Exchange  Commission under
     the Securities  Act of 1933,  and with any  applicable  state in compliance
     with the securities laws of such state (collectively, "Securities Laws") or
     unless the share  recipient  delivers a legal opinion  acceptable to BBAN's
     General   Counsel  that  such  sale  or  other   transfer  is  exempt  from
     registration in compliance with Securities Laws.  Appropriate stop transfer
     instructions  regarding such shares shall be given to BBAN's stock transfer
     agent. Each stock certificate issued to such recipients hereunder will bear
     a restrictive legend substantially as follows:

     The  shares  of  stock  represented  by  this  certificate  have  not  been
     registered  under the  Securities  Act of 1933,  as  amended,  or under the
     securities  laws of any state and may not be sold or otherwise  transferred
     unless in compliance with the registration provisions of such Act and state
     laws  or  unless  availability  of  an  exemption  from  such  registration
     provisions has been established.

          3. Authority, No Conflict. This Addendum constitutes the legal, valid,
     and binding ---------------------- obligation of BBAN and iTELL enforceable
     against each of them in accordance with the terms
