The payment of such fee shall not reduce the principal amount of the Incremental Facility Term Loan made by such Incremental Lender, and the disbursement of the proceeds of such Incremental Facility Term Loan, exclusive of the amount of such fee, shall satisfy such Incremental Lender’s Incremental Facility Term Loan Commitment relating thereto in full.

     15. Severability.    Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction.
