(a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the Applicable Rate on the daily amount (if any) by which the Commitment of such Lender exceeds the Revolving Credit Exposure of such Lender during the period from and including the Availability Date to but excluding the date on which such Commitment terminates. Commitment fees accrued through and including the last day of March, June, September and December of each year shall be payable in arrears on the fifteenth day after such last day (or if not a Business Day, the next following Business Day), commencing on the first such date to occur after the Availability Date; provided that accrued commitment fees shall be payable on the date on which the Commitments terminate. All commitment fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).
