Except for the LIBOR Cessation, the Credit Agreement and the other Loan Documents shall remain unchanged and in full force and effect, and the Agent and the Lenders expressly reserve the right to require strict compliance with the terms of the Credit Agreement and the other Loan Documents. Except as expressly set forth herein, the Credit Agreement and each other Loan Document is hereby ratified, approved and confirmed in each and every respect.
