(b)    Reducing Revolving Commitments. On each date set forth below, the Revolving Credit Facility shall be reduced by the amount set forth opposite such date below:

    (c)    Application of Commitment Reductions; Payment of Fees.

Debt Leverage Ratio would have resulted in higher pricing for such period, the Borrower shall immediately and retroactively be obligated to pay to the Administrative Agent for the account of the applicable Lenders or the L/C Issuer, as the case may be, promptly within ten (10) days of written demand by the Administrative Agent (or, after the occurrence of the entry of an order for relief with respect to the Borrower under the Bankruptcy Code of the United States, automatically and without further action by the Administrative Agent, any Lender or the L/C Issuer), an amount equal to the excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees actually paid for such period. This paragraph shall not limit the rights of the Administrative Agent, any Lender or the L/C Issuer, as the case may be, under Section 2.03(c)(iii), 2.03(h) or 2.07(b) or under Article VIII.

“(c)    Notwithstanding anything to the contrary herein or in any other Loan Document:

(i)     On March 5, 2021 the Financial Conduct Authority (“FCA”), the regulatory supervisor of LIBOR’s administrator (“IBA”), announced in a public statement the future cessation or loss of representativeness of overnight/Spot Next, 1-week, 1-month, 2-month, 3-month, 6-month and 12- month U.S. dollar LIBOR tenor settings. On the earliest of (A) the date that all Available Tenors of U.S dollar LIBOR have permanently or indefinitely ceased to be

provided by IBA or have been announced by the FCA pursuant to public statement or publication of information to be no longer representative, (B) June 30, 2023 and (C) the Early Opt-in Effective Date in respect of a SOFR Early Opt-in, if the then-current Benchmark is LIBOR, the Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any setting of such Benchmark on such day and all subsequent settings without any amendment to, or further action or consent of any other party to this Agreement or any other Loan Document. If the Benchmark Replacement is Daily Simple SOFR, all interest payments will be payable on a monthly basis.

(ii)    (x)    Upon (A) the occurrence of a Benchmark Transition Event or (B) a determination by the Administrative Agent that neither of the alternatives under clause (a) of the definition of Benchmark Replacement are available, the Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Lenders without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Lenders comprising the Required Lenders (and any such objection shall be conclusive and binding absent manifest error); provided that solely in the event that the then-current Benchmark at the time of such Benchmark Transition Event is not a SOFR-based rate, the Benchmark Replacement therefor shall be determined in accordance with clause (a) of the definition of Benchmark Replacement unless the Administrative Agent determines that neither of such alternative rates is available.

    (y)    On the Early Opt-in Effective Date in respect of an Other Rate Early Opt-in, the Benchmark Replacement will replace LIBOR for all purposes hereunder and under any Loan Document in respect of any setting of such Benchmark on such day and all subsequent settings without any amendment to, or further action or consent of any other party to this Agreement or any other Loan Document.

(iii)     At any time that the administrator of the then-current Benchmark has permanently or indefinitely ceased to provide such Benchmark or such Benchmark has been announced by the regulatory supervisor for the administrator of such Benchmark pursuant to public statement or publication of information to be no longer representative of the underlying market and economic reality that such Benchmark is intended to measure and that representativeness will not be restored, the Borrower may revoke any request for a borrowing of, conversion to or continuation of Loans to be made, converted or continued that would bear interest by reference to such Benchmark until the Borrower’s receipt of notice from the Administrative Agent that a Benchmark Replacement has replaced such Benchmark, and, failing that, the Borrower will be deemed to have converted any such request into a request for a borrowing of or conversion to Base Rate Loans. During the period referenced in the foregoing

sentence, the component of Base Rate based upon the Benchmark will not be used in any determination of Base Rate.

(iv)    In connection with the implementation and administration of a Benchmark Replacement, the Administrative Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement.

(v)    The Administrative Agent will promptly notify the Borrower and the Lenders of (A) the implementation of any Benchmark Replacement and (B) the effectiveness of any Benchmark Replacement Conforming Changes. Any determination, decision or election that may be made by the Administrative Agent pursuant to this Section 3.03(c), including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be conclusive and binding absent manifest error and may be made in its sole discretion and without consent from any other party hereto, except, in each case, as expressly required pursuant to this Section 3.03(c).

(vi)    At any time (including in connection with the implementation of a Benchmark Replacement), (A) if the then-current Benchmark is a term rate (including Term SOFR or LIBOR), then the Administrative Agent may remove any tenor of such Benchmark that is unavailable or non-representative for Benchmark (including Benchmark Replacement) settings and (B) the Administrative Agent may reinstate any such previously removed tenor for Benchmark (including Benchmark Replacement) settings.”
