(b)     References to LIBOR Rate and LIBOR Loans in the Credit Agreement and Loan Documents.

(i)     References to the LIBOR Rate and LIBOR Loans in provisions of the Credit Agreement and the other Loan Documents that are not specifically addressed herein (other than the definitions of LIBOR Rate and LIBOR Loan) shall be deemed to include Alternative Currency Daily Rates, Alternative Currency Term Rates, Alternative Currency Loans, Enhanced €STR and €STR Loans, as applicable; provided, that, references to the LIBOR Rate and LIBOR Loans in Section 2.01(d) of the Credit Agreement shall be deemed to be references to Enhanced €STR and €STR Loans, respectively.

(i)    Alternative Currency Loans.

Each such Committed Loan Notice must be received by the Administrative Agent not later than 11:00 a.m. (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. Each Borrowing of or continuation of Alternative Currency Loans shall be in a principal amount of the Dollar Equivalent of $1,000,000 or a whole multiple of the

Unless the Swing Line Lender has received notice (by telephone or in writing) from the Administrative Agent (including at the request of any Lender) prior to 12:00 p.m. (London time) on the date of the proposed Borrowing of Euro Swing Line Loans (A) directing the Swing Line Lender not to make such Euro Swing Line Loan as a result of the limitations set forth in the first proviso to the first sentence of Section 2.01(d)(i) of the Credit Agreement, or (B) that one or more of the applicable conditions specified in Section 4 of the Credit Agreement is not then satisfied, then, subject to the terms and conditions hereof, the Swing Line Lender will, not later than 1:00 p.m. (London time) on the Borrowing Date specified in such Committed Loan Notice, make the amount of its Euro Swing Line Loan available to the German Borrower.

(iii)    Conforming Changes. With respect to Enhanced €STR, 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 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 Borrower and the Lenders reasonably promptly after such amendment becomes effective.

    (iv)    Committed Loan Notice. For purposes of Borrowing a Euro Swing Line Loan, the German Borrower shall use the Committed Loan Notice attached hereto as Exhibit A.

(g)    Interest.

    (i)    Subject to the provisions of the Credit Agreement with respect to default interest, (x) each Alternative Currency Daily Rate Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Alternative Currency Daily Rate plus the Applicable Margin; (y) each Alternative Currency Term Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Alternative Currency Term Rate for such Interest Period plus the Applicable Margin and (z) each Euro Swing Line Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to Enhanced €STR plus the Applicable Margin.

    (ii)    Interest on each Alternative Currency Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified the Credit Agreement. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any debtor relief law.

(h)     Computations. All computations of interest for Alternative Currency Loans shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed, or, in the case of interest in respect of Alternative Currency Loans as to which market practice differs from the foregoing, in accordance with such market practice. All other computations of fees and interest with respect to €STR Loans shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year). Interest shall accrue on each Alternative Currency Loan for the day on which the Alternative Currency Loan or €STR Loan is made, and shall not accrue on an Alternative Currency Loan or €STR Loan, or any portion thereof, for the day on which the Alternative Currency Loan or €STR Loan or such portion thereof is paid, provided that any Alternative Currency Loan or €STR 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.

(i)    Successor Rates. The provisions in the Credit Agreement addressing the replacement of a current Successor Rate for a currency shall be deemed to apply to Alternative Currency Loans and SONIA, TIBOR and EURIBOR, as applicable, and the related defined terms shall be deemed to include Sterling, Yen and Euros and SONIA, TIBOR and EURIBOR, as applicable.
