 (e) Section 5.5 of the Existing Credit Agreement is hereby amended
and restated in its entirety to read as follows: 
 (a) If the Agent determines that (i) for any reason adequate and
reasonable means do not exist for determining the LIBOR for any requested Interest Period with respect to a proposed LIBOR Loan or (ii) the LIBOR Rate for any requested Interest Period with respect to a proposed LIBOR Loan does not adequately
and fairly reflect the cost to the Lenders of funding such LIBOR Loan, then, in each case of the foregoing, the Agent will promptly so notify the Borrower and each Lender thereof. Thereafter, the obligation of the Lenders to make or maintain LIBOR
Loans hereunder shall be suspended until the Agent revokes such notice in writing. Upon receipt of such notice, the Borrower may revoke any Notice of Borrowing or Notice of 

  
 -3- 













 
Continuation/Conversion then submitted by any of them. If the Borrower does not revoke such notice, the Lenders shall make, convert or continue the Loans, as proposed by the Borrower, in the
amount specified in the applicable notice submitted by the Borrower, but such Loans shall be made, converted or continued as Base Rate Loans instead of LIBOR Loans and the utilization of the LIBOR Rate component in determining the Base Rate shall be
suspended. 
 (b) Notwithstanding the foregoing, if the Agent has made the determination described in clause (a)(i) of
this Section 5.5 and/or is advised by the Required Lenders of their determination in accordance with clause (a)(ii) of this Section 5.5 and the Borrower shall so request, the Agent, the
Required Lenders and the Borrower shall negotiate in good faith to amend the definition of “Eurocurrency Rate” and other applicable provisions to preserve the original intent thereof in light of such change; provided that, until so
amended, such Loans impacted by clauses (a)(i) and (a)(ii) of this Section 5.5 will be handled as otherwise provided pursuant to the terms of this Section 5.5. 

(c) Benchmark Replacement Provisions. Notwithstanding anything to the contrary in this Agreement or in any other Loan
Document: 
 (i) Replacing USD LIBOR. On March 5, 2021 the Financial Conduct Authority (“FCA”),
the regulatory supervisor of USD LIBOR’s administrator (“IBA”), announced in a public statement the future cessation or loss of representativeness of overnight/Spot Next, 1-month, 3-month, 6-month and 12- month USD LIBOR tenor settings. On the earlier of (i) the date that all Available Tenors of USD LIBOR
have either 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 and (ii) the Early
Opt-in Effective Date, if the then-current Benchmark is USD 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 quarterly basis. 
 (ii) Replacing Future Benchmarks. Upon the occurrence of a Benchmark Transition
Event, 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 Agent has not received, by such time, written notice of objection
to such Benchmark Replacement from Lenders comprising the Required Lenders of each Class. 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 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 a determination of Base Rate. 

(iii) Benchmark Replacement Conforming Changes. In connection with the implementation and administration of a Benchmark
Replacement, the 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. 

  
 -4- 













 (iv) Notices: Standards for Decisions and Determinations. The Agent
will promptly notify the Borrower and the Lenders of (i) the implementation of any Benchmark Replacement and (ii) the effectiveness of any Benchmark Replacement Conforming Changes. Any determination, decision or election that may be made
by the Agent, or, if applicable, any Lender (or group of Lenders) pursuant to this Section 5.5(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 or their sole discretion and
without consent from any other party hereto, except, in each case, as expressly required pursuant to this Section 5.5(c). 

(v) Unavailability of Tenor of Benchmark. At any time (including in connection with the implementation of a Benchmark
Replacement), (i) if the then-current Benchmark is a term rate (including Term SOFR or USD LIBOR), then the Agent may remove any tenor of such Benchmark that is unavailable or nonrepresentative for Benchmark (including Benchmark Replacement)
settings and (ii) the Agent may reinstate any such previously removed tenor for Benchmark (including Benchmark Replacement) settings. 

(d) Certain Defined Terms. As used in this Section 5.5, the following terms have the following meanings: 

“Available Tenor” means, as of any date of determination and with respect to the then-current Benchmark, as
applicable, (x) if the then-current Benchmark is a term rate, any tenor for such Benchmark that is or may be used for determining the length of an Interest Period or (y) otherwise, any payment period for interest calculated with reference
to such Benchmark, as applicable, pursuant to this Agreement as of such date. 
 “Benchmark” means,
initially, USD LIBOR; provided that if a replacement of the Benchmark has occurred pursuant to Section 5.5(c), then “Benchmark” means the applicable Benchmark Replacement to the extent that such Benchmark
Replacement has replaced such prior benchmark rate. Any reference to “Benchmark” shall include, as applicable, the published component used in the calculation thereof. 

“Benchmark Replacement” means, for any Available Tenor: 

1) For purposes of Section 5.5(c)(i), the first alternative set forth below that can be determined by

six-months’ duration, or 
 b) the sum of: (i) Daily Simple SOFR and
(ii) the spread adjustment selected or recommended by the Relevant Governmental Body for the replacement of the tenor of USD LIBOR with a SOFR-based rate having approximately the same length as the interest payment period specified in
Section 5.5(c)(i); and 
 2) For purposes of Section 5.5(c)(ii), the sum
of (a) the alternate benchmark rate and (b) an adjustment (which may be a positive or negative value or zero), in each case, that has been selected by the Agent and the Borrower as the replacement for such Available Tenor of such Benchmark
giving due consideration to any evolving or then-prevailing market convention, including any applicable recommendations made by the Relevant Governmental Body, for U.S. dollar-denominated syndicated credit facilities at such time; 

provided that, if the Benchmark Replacement as determined pursuant to clause (1) or (2) above would be less than the Floor, the
Benchmark Replacement will be deemed to be the Floor for the purposes of this Agreement and the other Loan Documents.

timing and frequency of determining rates and making payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, the applicability and length of lookback periods, the applicability of breakage provisions,
and other technical, administrative or operational matters) that the Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by the Agent in a manner
substantially consistent with market practice (or, if the Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Agent determines that no market practice for the administration of such Benchmark
Replacement exists, in such other manner of administration as the Agent decides is reasonably necessary in connection with the administration of this Agreement and the other Loan Documents).

insolvency or resolution authority over the administrator for such Benchmark, announcing or stating that (a) such administrator has ceased or will cease on a specified date to provide all Available Tenors of such Benchmark, permanently or
indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide any Available Tenor of such Benchmark or (b) all Available Tenors of such Benchmark are or will
no longer be representative of the underlying market and economic reality that such Benchmark is intended to measure and that representativeness will not be restored. 

“Daily Simple SOFR” means, for any day, SOFR, with the conventions for this rate (which will include a
lookback) being established by the Agent in accordance with the conventions for this rate recommended by the Relevant Governmental Body for determining “Daily Simple SOFR” for syndicated business loans; provided, that if the Agent

 “Early Opt-in Election” means the occurrence of: 
 1) a notification by the Agent to (or
the request by the Borrower to the Agent to notify) each of the other parties hereto that at least five currently outstanding U.S. dollar-denominated syndicated credit facilities at such time contain (as a result of amendment or as originally
executed) a SOFR-based rate (including SOFR, a term SOFR or any other rate based upon SOFR) as a benchmark rate (and such syndicated credit facilities are identified in such notice and are publicly available for review), and 

2) the joint election by the Agent and the Borrower to trigger a fallback from USD LIBOR and the provision by the Agent of
written notice of such election to the Lenders. 
 “Floor” means the benchmark rate floor, if any, provided
in this Agreement initially (as of the execution of this Agreement, the modification, amendment or renewal of this Agreement or otherwise) with respect to USD LIBOR. 

“Relevant Governmental Body” means the Board of Governors of the Federal Reserve System or the Federal Reserve
Bank of New York, or a committee officially endorsed or convened by the Board of Governors of the Federal Reserve System or the Federal Reserve Bank of New York, or any successor thereto.

individually and collectively, a “Payment”) and demands the return of such Payment, such Recipient shall promptly, but in no event later than one Business Day thereafter, return to the Agent the amount of any such Payment as to
which such a demand was made. A notice of the Agent to any Recipient under this Section shall be conclusive, absent manifest error. 

(b) Without limitation of clause (a) above, each Recipient further acknowledges and agrees that if such Recipient receives

Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation from time to time in effect. Each Recipient hereby agrees that it shall not assert and, to the fullest extent permitted by applicable law,
hereby waives, any right to retain such Payment, and any claim, counterclaim, defense or right of set-off or recoupment or similar right to any demand by the Agent for the return of any Payment received,
including without limitation any defense based on “discharge for value” or any similar doctrine. 
 (d) The
Borrower and each other Obligor hereby agrees that (x) in the event an erroneous Payment (or portion thereof) is not recovered from any Lender that has received such Payment (or portion thereof) for any reason, the Agent shall be subrogated to
