Each such Committed Loan Notice must be received by the Administrative Agent not later than 12:00 noon (Eastern time) three Business Days (or five Business Days in the case of a Special Notice Currency) prior to the requested date of any Borrowing or, in the case of Alternative Currency Term Rate Loans, any continuation.

(ii) Conforming Changes. With respect to any Alternative Currency Rate the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein, in the Credit Agreement or in any

154871773_5 other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement, the Credit Agreement or any other Loan Document; provided, that, with respect to any such amendment effected, the Administrative Agent shall post each such amendment implementing such Conforming Changes to the Company and the Lenders reasonably promptly after such amendment becomes effective.

Interest shall accrue on each Alternative Currency Loan for the day on which the Alternative Currency Loan is made, and shall not accrue on an Alternative Currency Loan, or any portion thereof, for the day on which the Alternative Currency Loan or such portion is paid, provided that any Alternative Currency Loan that is repaid on the same day on which it is made shall, subject to the terms of the Credit Agreement, bear interest for one day. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error. (h) Successor Rates.
