(g)Section 2.12(a)(ii) of the Credit Agreement is hereby amended and restated to read in its entirety as follows:

“(ii)Payments by Borrower; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or any L/C Issuer hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the applicable L/C Issuers, as the case may be, the amount due.

With respect to any payment that the Administrative Agent makes for the account of the Lenders or any L/C Issuer hereunder as to which the Administrative Agent determines (which determination shall be conclusive absent manifest error) that any of the following applies (such payment referred to as the “Rescindable Amount”): (1) the Borrower has not in fact made such payment; (2) the Administrative Agent has made a payment in excess of the amount so paid by the Borrower (whether or not then owed); or (3) the Administrative Agent has for any reason otherwise erroneously made such payment; then each of the Lenders or the applicable L/C Issuers, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the Rescindable Amount so distributed to such Lender or such L/C Issuer, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

A notice of the Administrative Agent to any Lender or the Borrower with respect to any amount owing under this clause (a) shall be conclusive, absent manifest error.”

(h)Section 3.03 of the Credit Agreement is hereby amended to restate clauses (c) through (f) thereof in their entirety to read as follows:

“(c)Notwithstanding anything to the contrary in this Agreement or any other Loan Documents, if the Administrative Agent reasonably determines (which determination shall be conclusive absent manifest error), or the Borrower or Required Lenders notify the Administrative Agent (with, in the case of the Required Lenders, a copy to the Borrower) that the Borrower or Required Lenders (as applicable) have determined, that:

(i)adequate and reasonable means do not exist for ascertaining LIBOR for any Interest Period hereunder or any other tenors of LIBOR, including, without limitation, because the LIBOR Screen Rate is not available or published on a current basis and such circumstances are unlikely to be temporary; or

(ii)the administrator of the LIBOR Screen Rate or a Governmental Authority having jurisdiction over the Administrative Agent or such administrator has made a public statement identifying a specific date after which LIBOR or the LIBOR Screen Rate shall no longer be made available, or used for determining the interest rate of loans, provided that, at the time of such statement, there is no successor administrator that is satisfactory to the Administrative Agent, that will continue to provide LIBOR after such specific date (such specific date, the “Scheduled Unavailability Date”); or

(iii)the administrator of the LIBOR Screen Rate or a Governmental Authority having jurisdiction over such administrator has made a public statement announcing that all Interest Periods and other tenors of LIBOR are no longer representative; or

(iv)syndicated loans currently being executed, or that include language similar to that contained in this Section 3.03, are being executed or amended (as applicable) to incorporate or adopt a new benchmark interest rate to replace LIBOR;

then, in the case of clauses (i)-(iii) above, on a date and time determined by the Administrative Agent (any such date, the “LIBOR Replacement Date”), which date shall be at the end of an Interest Period or on the relevant interest payment date, as applicable, for interest calculated and shall occur reasonably promptly upon the occurrence of any of the events or circumstances under clauses (i), (ii) or (iii) above and, solely with respect to clause (ii) above, no later than the Scheduled Unavailability Date, LIBOR will be replaced hereunder and under any Loan Document with, subject to the proviso below, the first available alternative set forth in the order below for any payment period for interest calculated that can be determined by the Administrative Agent, in each case, without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document (the “LIBOR Successor Rate”; and any such rate before giving effect to the Related Adjustment, the “Pre-Adjustment Successor Rate”):

(x)Term SOFR plus the Related Adjustment; and

(y) SOFR plus the Related Adjustment;

and in the case of clause (iv) above, the Borrower and Administrative Agent may amend this Agreement solely for the purpose of replacing LIBOR under this Agreement and under any other Loan Document in accordance with the definition of “LIBOR Successor Rate” and such amendment will become effective at 5:00 p.m., on the fifth Business Day after the Administrative Agent shall have notified all Lenders and the Borrower of the occurrence of the circumstances described in clause

(iv) above unless, prior to such time, Lenders comprising the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders object to the implementation of a LIBOR Successor Rate pursuant to such clause;

provided that, if the Administrative Agent determines that Term SOFR has become available, is administratively feasible for the Administrative Agent and would have been identified as the Pre-Adjustment Successor Rate in accordance with the foregoing if it had been so available at the time that the LIBOR Successor Rate then in effect was so identified, and the Administrative Agent notifies the Borrower and each Lender of such availability, then from and after the beginning of the Interest Period, relevant interest payment date or payment period for interest calculated, in each case, commencing no less than thirty (30) days after the date of such notice, the Pre-Adjustment Successor Rate shall be Term SOFR and the LIBOR Successor Rate shall be Term SOFR plus the relevant Related Adjustment.

The Administrative Agent will promptly (in one or more notices) notify the Borrower and each Lender of (x) any occurrence of any of the events, periods or circumstances under clauses (i) through (iii) above, (y) a LIBOR Replacement Date and (z) the LIBOR Successor Rate.

Any LIBOR Successor Rate shall be applied in a manner consistent with market practice; provided that to the extent such market practice is not administratively feasible for the Administrative Agent, such LIBOR Successor Rate shall be applied in a manner as otherwise reasonably determined by the Administrative Agent.

Notwithstanding anything else herein, if at any time any LIBOR Successor Rate as so determined would otherwise be less than 0%, the LIBOR Successor Rate will be deemed to be 0%for the purposes of this Agreement and the other Loan Documents.

In connection with the implementation of a LIBOR Successor Rate, the Administrative Agent will have the right to make LIBOR Successor Rate Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such LIBOR Successor Rate Conforming Changes will become effective without any further action or consent of any other party to this Agreement; provided that, with respect to any such amendment effected, the Administrative Agent shall post each such amendment implementing such LIBOR Successor Rate Conforming Changes to the Borrower and the Lenders reasonably promptly after such amendment becomes effective.

If the events or circumstances of the type described in 3.03(c)(i)-(iii) have occurred with respect to the LIBOR Successor Rate then in effect, then the successor rate thereto shall be determined in accordance with the definition of “LIBOR Successor Rate.”

(d)Notwithstanding anything to the contrary herein, (i) after any such determination by the Administrative Agent or receipt by the Administrative Agent of any such notice described under Section 3.03(c)(i)-(iii), as applicable, if the Administrative Agent determines that none of the LIBOR Successor Rates is available on or prior to the LIBOR Replacement Date, (ii) if the events or circumstances described in Section 3.03(c)(iv) have occurred but none of the LIBOR Successor Rates is available, or (iii) if the events or circumstances of the type described in Section 3.03(c)(i)-(iii) have occurred with respect to the LIBOR Successor Rate then in effect and the Administrative Agent determines that none of the LIBOR Successor Rates is available, then in each case, the Administrative Agent and the Borrower may amend this Agreement solely for the purpose of replacing LIBOR or any then current LIBOR Successor Rate in accordance with this Section 3.03 at the end of any Interest Period, relevant interest payment date or payment period for interest calculated, as applicable, with another alternate benchmark rate giving due consideration to any evolving or then existing convention for similar U.S. dollar denominated syndicated credit facilities for such alternative benchmarks and, in each case, including any Related Adjustments and any other mathematical or other adjustments to such benchmark giving due consideration to any evolving or then existing convention for similar U.S. dollar denominated syndicated credit facilities for such benchmarks, which adjustment or method for calculating such adjustment shall be published on an information service as selected by the Administrative Agent from time to time in its reasonable discretion and may be periodically updated. For the avoidance of doubt, any such proposed rate and adjustments shall constitute a LIBOR Successor Rate. Any such amendment shall become effective at 5:00 p.m. on the fifth Business Day after the Administrative Agent shall have posted such proposed amendment to all Lenders and the Borrower unless, prior to such time, Lenders comprising the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders object to such amendment.

(e)If, at the end of any Interest Period, relevant interest payment date or payment period for interest calculated, no LIBOR Successor Rate has been determined in accordance with clauses (c) or (d) of this Section 3.03 and the circumstances under clauses (c)(i) or (c)(iii) above exist or the Scheduled Unavailability Date has occurred (as applicable), the Administrative Agent will promptly so notify the Borrower and each Lender. Thereafter, (x) the obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended, (to the extent of the affected Eurodollar Rate Loans, Interest Periods, interest payment dates or payment periods), and (y)

the Eurodollar Rate component shall no longer be utilized in determining the Base Rate, until the LIBOR Successor Rate has been determined in accordance with clauses (c) or (d). Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans (to the extent of the affected Eurodollar Rate Loans, Interest Periods, interest payment dates or payment periods) or, failing that, will be deemed to have converted such request into a request for a Committed Borrowing of Base Rate Loans (subject to the foregoing clause (y)) in the amount specified therein.”

(i)Article IX is hereby amended to add a new Section 9.13 to the end thereof to read in its entirety as follows:

“9.13Recovery of Erroneous Payments. Without limitation of any other provision in this Agreement, if at any time the Administrative Agent makes a payment hereunder in error to any Lender or any L/C Issuer (the “Credit Party”), whether or not in respect of an Secured Obligation due and owing by the Borrower at such time, where such payment is a Rescindable Amount, then in any such event, each Credit Party receiving a Rescindable Amount severally agrees to repay to the Administrative Agent forthwith on demand the Rescindable Amount received by such Credit Party in immediately available funds in the currency so received, with interest thereon, for each day from and including the date such Rescindable Amount is received by it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. Each Credit Party irrevocably waives any and all defenses, including any “discharge for value” (under which a creditor might otherwise claim a right to retain funds mistakenly paid by a third party in respect of a debt owed by another) or similar defense to its obligation to return any Rescindable Amount. The Administrative Agent shall inform each Credit Party promptly upon determining that any payment made to such Credit Party comprised, in whole or in part, a Rescindable Amount.”

(j)Section 11.01(f) of the Credit Agreement is hereby amended and restated to read in its entirety as follows:

“(f)(i) without the prior written consent of each Lender directly, adversely affected thereby (A) modify Sections 8.03 or 2.13 in a manner that would have the effect of altering the pro rata sharing of payments otherwise required hereunder, (B) subordinate, or have the effect of subordinating, the Secured Obligations hereunder to any other Indebtedness and (C) except as provided in Section 9.10, subordinate, or have the effect of subordinating, the Liens securing the Secured Obligations to Liens securing any other Indebtedness or (ii) modify the order of application of any reduction in the Commitments or any prepayment of Loans among the Facilities from the application thereof set forth in the applicable provisions of Section 2.05(b) or 2.06(c), respectively, in any manner that materially and adversely affects the Lenders under a Facility without the written consent of (x) if such Facility is the Term Facility, the Required Term Lenders and (y) if such Facility is the Revolving Credit Facility, the Required Revolving Lenders;”

(k)Annex I to the Credit Agreement is hereby amended by replacing it in its entirety with Annex I attached hereto as Annex A.
