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, 

  
 -2- 













 
the Borrower may revoke any Notice of Borrowing or Notice of 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, 

  
 -3- 













 
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. 

(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 non-representative 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. 

  
 -4- 













 “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 the Agent: 
 a) the sum of: (i) Term SOFR and (ii) 0.11448% (11.448 basis points) for
an Available Tenor of one-month’s duration, 0.26161% (26.161 basis points) for an Available Tenor of three-months’ duration, and 0.42826% (42.826 basis points) for an Available Tenor of 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. 

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical,
administrative or operational changes (including changes to the definition of “Base Rate,” the definition of “Business Day,” the definition of “Interest Period,” 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).

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
decides that any such convention is not administratively feasible for the Agent, then the Agent may establish another convention in its reasonable discretion. 

“Early Opt-in Effective Date” means, with respect to any Early Opt-in Election, the sixth (6th) Business Day after the date notice of such Early Opt-in Election is provided to the Lenders, so long as the Agent has not received, by 5:00
p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Early Opt-in Election is provided to the Lenders, written notice of
objection to such Early Opt-in Election from Lenders comprising the Required Lenders. 

“Early Opt-in Election” means the occurrence of:

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.

the Federal Reserve Bank of New York (or a successor administrator of the secured overnight financing rate) on the website of the Federal Reserve Bank of New York, currently at http://www.newyorkfed.org (or any successor source for the secured
overnight financing rate identified as such by the administrator of the secured overnight financing rate from time to time).

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

“Payment Notice”), (y) that was not preceded or accompanied by a Payment Notice, or (z) that such Recipient otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part), in each case, it
