         Aggregate Commitments (as defined below) for such Utilization Period,

         the Lenders an additive usage fee (the "Additive Usage Fee") calculated
         as provided below, for such Utilization Period. The Additive Usage Fee
         shall be payable in arrears on the 15th day following the last day of
         such Utilization Period. The Additive Usage Fee for any Utilization
         Period shall be equal to the following amounts for each day in such

                           (i) if the Average Outstanding Loans for such
                  Utilization Period is greater than or equal to twenty-five
                  percent (25%), but less than fifty percent (50%) of the

                  Utilization Period, ten basis points (.10%) per annum
                  multiplied by the actual principal balance of the Committed
                  Revolving Loans outstanding under this Agreement at the end of
                  such day;

                          (ii) if the Average Outstanding Loans for such
                 Utilization Period is greater than or equal to fifty percent
                 (50%), but less than seventy-five percent (75%) of the average
                 of the daily Aggregate Commitments for such Utilization Period,
                 twenty basis points (.20%) per annum multiplied by the actual
                 principal balance of the Committed Revolving Loans outstanding
                 under this Agreement at the end of such day; or

                          (iii) if the Average Outstanding Loans for such

                  The Additive Usage Fee for any Utilization Period shall be
         allocated among the Lenders in accordance with the amount of their
         respective Committed Revolving Loans outstanding under this Agreement
         during such Utilization Period. For purposes hereof, (A) "Average
         Outstanding Loans" for any Utilization Period means the sum of the
         aggregate principal amount of Committed Revolving Loans outstanding
         under this Agreement as of the end of each day during such Utilization
         Period, divided by the number of days in such Utilization Period; (B)
         "Aggregate Commitment" for any Utilization Period means the aggregate
         amount of the Revolving Commitment; and (C) "Utilization Period" means
