Notwithstanding any other provision hereof, if any Lender shall reasonably determine that any law, regulation, treaty or directive, or any change therein or in the interpretation or application thereof, shall make it unlawful for such Lender to make or maintain any Eurodollar Advance as contemplated by this Agreement, such Lender shall promptly notify the Borrower and the Administrative Agent thereof, and (a) the commitment of such Lender to make such Eurodollar Advances or Convert ABR Advances to such Eurodollar Advances shall forthwith be suspended, (b) such Lender shall fund its portion of each requested Eurodollar Advance as an ABR Advance and (c) such Lender’s Loans then outstanding as such Eurodollar Advances, if any, shall be Converted automatically to an ABR Advance on the last day of the then current Interest Period applicable thereto or at such earlier time as may be required. If the commitment of any Lender with respect to Eurodollar Advances is suspended pursuant to this Section and such Lender shall have obtained actual knowledge that it is once again legal for such Lender to make or maintain Eurodollar Advances, such Lender shall promptly notify the Administrative Agent and the Borrower thereof and, upon receipt of such notice by each of the Administrative Agent and the Borrower, such Lender’s commitment to make or maintain Eurodollar Advances shall be reinstated. If the commitment of any Lender with respect to Eurodollar Advances is suspended pursuant to this Section, such suspension shall not otherwise affect such Lender’s Commitment.
