(a) The Revolver Borrowers agree, on a several and not joint basis , to pay to the Revolver Administrative Agent for the account of each Revolving Credit Lender (other than any Defaulting Lender) a commitment fee, which shall accrue at a rate equal to the Revolving Commitment Fee Rate per annum applicable to the Revolving Credit Commitments on the actual daily unused amount of the Revolving Credit Commitment of such Revolving Credit Lender during the period from and including the Closing Date to but excluding the date on which such Lender’s Revolving Credit Commitment terminates. The foregoing notwithstanding, the applicable lenders may consent to a different commitment fee to be paid pursuant to the terms of any applicable Incremental Facility Amendment, Replacement Facility Amendment or Extension Offer. Accrued commitment fees shall be payable in arrears on the last Business Day of March, June, September and December of each year and on the date on which the Revolving Credit Commitments terminate, commencing on the last day of December 2018. 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 calculating the commitment fee only, the Revolving Credit Commitment of any Revolving Credit Lender shall be deemed to be used to the extent of Revolving Credit Loans of such Revolving Credit Lender and the LC Exposure of such Revolving Credit Lender.
