(a) The Borrowers jointly and severally agree to pay to the Administrative Agent for the account of the Revolving Banks a commitment fee, which shall accrue at the Applicable Margin on the daily unused amount of the Revolving Commitments of each Revolving Bank during the period from and including the date hereof to but excluding the date on which such Revolving Commitment terminates. Accrued commitment fees shall be payable quarterly in arrears on each March 31, June 30, September 30 and December 31 of each year, commencing on the first such date to occur after the date of this Agreement, and upon the date of termination of the Revolving Commitments in their entirety. 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). For purposes of computing commitment fees, a Revolving Commitment of a Bank shall be deemed to be used to the extent of the outstanding Revolving Loans and LC Exposure in respect of such Class of such Bank (and any Swingline Exposure of such Bank shall be disregarded for such purpose and no portion of the Dollar Revolving Commitments shall be deemed utilized as a result of outstanding Swingline Loans).
