 $25,000,000.00                                              St. Louis, Missouri
                                                             September 28, 1999

          FOR VALUE  RECEIVED,  on the last day of the Revolving  Credit Period,
 the  undersigned,   INTERLOTT   TECHNOLOGIES,   INC.,  a  Delaware  corporation
 ("Borrower"), hereby promises to pay to the order of MERCANTILE BUSINESS CREDIT
 INC., a Missouri  corporation  ("Lender"),  the  principal  sum of  Twenty-Five
 Million Dollars ($25,000,000.00), or such lesser sum as may then constitute the
 aggregate  unpaid principal amount of all Revolving Credit Loans made by Lender
 to Borrower  pursuant to the Loan  Agreement  referred to below.  The aggregate
 principal  amount of Revolving  Credit Loans which Lender shall be committed to
 have outstanding  under this Note at any one time shall not exceed  Twenty-Five
 Million  Dollars   ($25,000,000.00),   which  amount  may  be  borrowed,  paid,
 reborrowed and repaid, in whole or in part, subject to the terms and conditions
 of this Note and of the Loan Agreement referred to below.

          Borrower  further  promises to pay to the order of Lender  interest on
 the unpaid principal  balance from time to time outstanding  under this Note on
 the dates and at the rates set forth in the Loan  Agreement  referred to below.
 All payments  received by Lender  under this Note shall be allocated  among the
 principal,  interest, collection costs and expenses and other amounts due under
 this  Note as  follows:  (a) so long as no  Event  of  Default  under  the Loan
 Agreement has occurred and is continuing,  as directed by Borrower;  and (b) so
 long as any Event of  Default  under the Loan  Agreement  has  occurred  and is
 continuing,  in such  order and  manner as Lender  shall  elect.  The amount of
 interest  accruing under this Note shall be computed on an actual day,  360-day
 year basis.

          All payments of principal  and interest  under this Note shall be made
 in lawful currency of the United States at the office of Lender situated at 100
 South  Brentwood  Boulevard,  Suite 500, St. Louis,  Missouri 63105, or at such
 other  place as the  holder  of this Note may from  time to time  designate  in
 writing.

          Lender  shall  record in its books and  records the date and amount of
 each  Revolving  Credit Loan made by it to Borrower  and the date and amount of
 each  payment of  principal  and/or  interest  made by  Borrower  with  respect
 thereto;  provided,  however,  that the  obligation  of  Borrower to repay each
 Revolving  Credit Loan made to Borrower  under this Note shall be absolute  and
 unconditional,   notwithstanding  any  failure  of  Lender  to  make  any  such
 recordation or any mistake by Lender in connection  with any such  recordation.
 The books and records of Lender showing the account between Lender and Borrower
 shall  be  admissible  in  evidence  in any  action  or  proceeding  and  shall
 constitute  prima facie proof of the items  therein set forth in the absence of
 manifest error.

          Subject to the terms of the Loan Agreement referred to below, Borrower
 shall have the right to prepay all at any time or any portion from time to time
 of the unpaid  principal  of this Note prior to  maturity,  without  penalty or
 premium.

          This Note is the  Revolving  Credit Note  referred to in that  certain
 Loan Agreement  dated October 29, 1997 by and between  Borrower and Lender,  as
 amended by that certain First  Amendment to Loan Agreement  dated as of October
 29, 1998 and that certain  Second  Amendment to Loan  Agreement  dated the date
 hereof  (as so  amended,  and as the  same  may  from  time to time be  further
 amended, modified, extended,

 renewed or restated,  the "Loan  Agreement").  The Loan Agreement,  among other
 things,  contains provisions for acceleration of the maturity of this Note upon
 the occurrence of certain stated events and also for  prepayments on account of
 the  principal  of this Note and interest on this Note prior to the maturity of
 this Note upon the terms and  conditions  specified  therein.  All  capitalized
 terms used and not  otherwise  defined  in this Note shall have the  respective
 meanings ascribed to them in the Loan Agreement.

           This Note is secured by, among other  things,  that certain  Security
 Agreement  dated  October 29, 1997 and  executed by Borrower in favor of Lender
 (as the same may from time to time be amended,  modified,  extended, renewed or
 restated,  the "Security  Agreement")  and that certain  Patent,  Trademark and
 License  Security  Agreement dated October 29, 1997 and executed by Borrower in
 favor  of  Lender  (as the same may  from  time to time be  amended,  modified,
 extended,  renewed or restated,  the "Patent,  Trademark  and License  Security
 Agreement"),  to which  Security  Agreement  and Patent,  Trademark and License
 Security  Agreement  reference is hereby made for a description of the security
 and a statement of the terms and conditions upon which this Note is secured.

           If any Event of Default under the Loan  Agreement  shall occur and be
 continuing,  then Lender's obligation to make additional Revolving Credit Loans
 under this Note may be terminated in the manner and with the effect as provided
 in the Loan Agreement and the entire outstanding principal balance of this Note
 and all accrued and unpaid  interest  thereon may be declared to be immediately
 due and  payable  in the manner  and with the  effect as  provided  in the Loan
 Agreement.

           In the event that arty  payment of any  principal  of or  interest on
 this Note is not paid when due, whether by reason of maturity,  acceleration or
 otherwise, and this Note is placed in the hands of an attorney or attorneys for
 collection  or  for  foreclosure  of the  Security  Agreement  or  the  Patent,
 Trademark  and  License  Security  Agreement,  or if this Note is placed in the
 hands of an attorney or attorneys  for  representation  of Lender in connection
 with bankruptcy or insolvency proceedings relating hereto, Borrower promises to
 pay to the order of Lender,  in addition  to all other  amounts  otherwise  due
 hereon,   the  costs  and  expenses  of  such   collection,   foreclosure   and
 representation,  including, without limitation,  reasonable attorneys' fees and
 expenses  (whether or not  litigation  shall be commenced in aid thereof).  All
 parties hereto  severally waive  presentment  for payment,  demand for payment,
 protest, notice of protest and notice of dishonor.

           This Note shall be governed by and construed in  accordance  with the
 substantive laws of the State of Missouri (without reference to conflict of law
 principles).

         This Note is an amendment, restatement and continuation of that certain

thereof.  All interest  accrued on the instrument  being amended and restated by
this Note shall continue to be due and payable to Lender until paid.
