Loan or request with respect to a Loan, (a) Agent determines that (i) Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable Loan amount or Interest Period, or (ii) adequate and
reasonable means do not exist for determining LIBOR for the Loan or Interest Period (including with respect to calculation of the Base Rate); or (b) Agent or Required Lenders determine for any reason that LIBOR for the Interest Period does not
adequately and fairly reflect the cost to Lenders of funding or maintaining the Loan. Thereafter, Lenders’ obligations to make or maintain affected LIBOR Loans and utilization of the LIBOR component (if affected) in determining Base Rate shall
be suspended until Agent determines (or is instructed by Required Lenders) to withdraw the notice. Upon receipt of such notice, Borrower may revoke any pending request for funding, conversion or continuation of a LIBOR Loan or, failing that, will be
deemed to have requested a Base Rate Loan, and the Administrative Agent may (or shall upon request by Required Lenders) immediately convert any affected LIBOR Loan to a Base Rate Loan. 

  
 4 













 (b)    Notwithstanding anything to the contrary in this
Agreement or any other Loan Documents, if the Administrative Agent 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; 

(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”); 
 (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, 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 the other Loan Documents 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 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 (“LIBOR Successor Rate”;
and any such rate before giving effect to the Related Adjustment, “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 

  
 5 













 
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, 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 notifies the Borrower and Lenders 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 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 Lenders 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 1.0%, the LIBOR Successor Rate will be deemed to be 1.0% 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 deliver 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 clauses (i) through (iii) above 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.” 
 (c)    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(b)(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  

  
 6 













 
3.03(b)(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(b)(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 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 delivered such proposed amendment to Lenders and the Borrower unless, prior to such time, the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders object to such amendment. 

(d)    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 subsections 3.03(b) and (c) above and the circumstances under clauses (a)(i) or (b)(iii) of subsection 3.03(b) 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 LIBOR Loans shall be suspended (to
the extent of the affected LIBOR Loans, Interest Periods, interest payment dates or payment periods), and (y) the LIBOR component shall no longer be utilized in determining Base Rate, until the LIBOR Successor Rate has been determined in
accordance with subsections 3.03(b) and (c) above. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of LIBOR Loans (to the extent of the affected LIBOR
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 Base Rate Loan (subject to the foregoing clause (y)) in the amount specified
therein.”

Section 6.20 to read in its entirety as follows:
