         new lenders to the Agreement added by way of this addendum (i.e.  Lloyd
         E.  Shefsky,  OZF Ltd.  and  Clarenville  Ltd.)  shall be  deemed to be
         "Lenders" under the Agreement in all respects, with accompanying rights
         and  obligations  associated  with that term being  assumed by such new
         lenders as if they were original  signatories  to the  Agreement;  (ii)
         agree that the signatures  hereon by such new lenders shall  constitute
         their  signature  to those  agreements  attached  to the  Agreement  as
         Exhibits that were  previously  executed by all Lenders  independent of
         the execution of the Agreement; (iii) waive any claim, right or defense
         against any other party including against any new lender,  based on the
         fact that the Second Tranche  exceeds  $750,000;  (iv) waive any claim,
         right or defense  against  any other  party  including  against any new
         lender,   based  on  any  delay  in  providing   notice  of  intent  to
         participate,  or funding,  which  occurred prior to the signing of this
         Addendum or lack of participation in the First Tranche; (v) acknowledge
         that each party has the  obligation  to  ascertain  for itself that all
         closing conditions have been satisfied; (vi) acknowledge that s.10.2 of
         the  Agreement  is amended  for new lenders to oblige them only to fund
         the  Second  Tranche.

     c.  The  new  lenders   confirm  having  had  the   opportunity  to  obtain
         independent  legal advice,  to do due diligence  satisfactory for their
         purposes,  and to review the  Convertible  Loan Agreement dated January
         29,  2003  and  all  exhibits  and  schedules  therein,   or  documents
         incorporated by reference.

     d.  The  Company  confirms  it is  not  in  default  under  the  Agreement,
         including the promissory  notes, and any other document  referred to in
         the Agreement.

     e.  Except to the extent  amended  hereby,  the terms and conditions of the
         Agreement  shall remain in full force and effect as between the parties
         hereto throughout the term of the Agreement.
