        at  any  time  not  to  exceed  Twenty  Million  Dollars   ($20,000,000)
        (collectively,  the  "Floorplan  Inventory  Loan  Facility");  provided,
        however,  that at no time will the sum of principal  amount  outstanding
        under the Floorplan Inventory Loan Facility plus the principal amount of
        outstanding  Working  Capital Loans  exceed,  in the  aggregate,  Twenty
        Million Dollars  ($20,000,000.00);  and provided,  further,  that on and
        after April 15, 2001,  the  Floorplan  Inventory  Loan  Facility will be
        reduced to Ten Million Dollars  ($10,000,000) and at no time on or after
        April 15, 2001 will the sum of the principal  amount  outstanding  under

               as no Default exists, to provide to Borrower, and Borrower agrees
               to  accept,  working  capital  financing  (each  advance  being a
