assigns,  the  "Borrower"),  hereby  promises to pay to the order of BILLFIGHTER
INVESTMENTS,  LIMITED,  an Anguilla limited liability company (together with its
successors and assigns, the "Lender"), at the Lender's offices located at Hannah
Waiver  House,  The Valley,  Anguilla BWI (or such other place as the Lender may
designate  in writing  to the  Borrower),  the  aggregate  principal  sum of One
Hundred Eighty  Thousand  Dollars  ($180,000) with interest with interest on the
balance  outstanding  from  time to time at the rate of ten  percent  (10%)  per

conditions set forth herein. This unsecured  promissory note (the "Note") is the
promissory note referred to Section 3.3 of the License Agreement,  dated of even
date  herewith  (the  "License  Agreement")  by and  between  the Lender and the
Borrower.

1.    Payment and Prepayment.

      (a)   Repayment of Principal  and Interest.  The entire  unpaid  principal
            balance, together with any accrued interest and other unpaid charges
            or fees hereunder,  shall be due and payable on first anniversary of
            the date hereof (the "Maturity Date").

      (b)   Prepayment.  Prepayment  in  whole  or part  may  occur  at any time
            hereunder without penalty or premium; provided that the Lender shall
            be  provided  with  not  less  than  ten  (10)  days  notice  of the
            Borrower's  intent to pre-pay;  and  provided  further that any such
            partial  prepayment  shall not  operate to  postpone  or suspend the
            obligation  to make,  and shall not have the effect of altering  the
            time for  payment of the  remaining  balance of the Note as provided
            for above,  unless and until the entire  obligation is paid in full.
            All payments  received  hereunder  shall be applied,  first,  to any
            costs or expenses  incurred by Lender in collecting  such payment or
            to any other unpaid  charges or expenses due hereunder;  second,  to
            accrued interest; and third, to principal.
