consistent with market practice (or, if the Administrative Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Administrative Agent determines that no market practice for the administration
of the Benchmark Replacement exists, in such other manner of administration as the Administrative Agent decides is reasonably necessary in connection with the administration of this Agreement).

without consent from any other party hereto, except, in each case, as expressly required pursuant to this Section 3.03(b).

commencement of a Benchmark Unavailability Period, the Borrower may revoke any request for a Eurodollar Loan of, conversion to or continuation of Eurodollar Loans to be made, converted or continued during any Benchmark Unavailability Period and,
failing that, the Borrower will be deemed to have converted any such request into a request for a borrowing of or conversion to ABR Loans. During any Benchmark Unavailability Period, the component of the Alternate Base Rate based upon the LIBO Rate
will not be used in any determination of the Alternate Base Rate.

 Section 12.19    Acknowledgement Regarding Any Supported QFCs. To the
extent that the Loan Documents provide support, through a guarantee or otherwise, for any Swap Agreement or any other agreement or instrument that is a QFC (such support, “QFC Credit Support”, and each such QFC, a “Supported
QFC”), the parties acknowledge and agree as follows with respect to the resolution power of 

  
 Page 6 

 
the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations
promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact
be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States): 

(a)    In the event a Covered Entity that is party to a Supported QFC (each, a “Covered
Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC
Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the
Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a Covered Party or a BHC Act Affiliate of a Covered
Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are
permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United
States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC
Credit Support. 
 (b)    As used in this Section 12.19, the following terms
have the following meanings: 
 “BHC Act Affiliate” of a party means an “affiliate” (as such term
is defined under, and interpreted in accordance with, 12 U.S.C. 1841(k)) of such party. 
 “Covered Entity”
means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance
with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). 

“Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12
C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. 
 “QFC” has the meaning assigned to the term
“qualified financial contract” in, and shall be interpreted in accordance with, 12 U.S.C. 5390(c)(8)(D).

representations and warranties are expressly limited to an earlier date, in which case, such representations and warranties shall continue to be true and correct in all material respects as of such specified earlier date and (B) any such
representation and warranty is expressly limited by materiality or by reference to Material Adverse Effect, in which case, such representation and warranty is true and correct in all respects) and (ii) no Default or Event of Default has
occurred and is continuing.

hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Third Amendment by fax, as an
attachment to an email or other similar electronic means shall be effective as delivery of a manually executed counterpart of this Third Amendment.

the parties hereto and thereto and may not be contradicted by evidence of prior, contemporaneous, or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties.

particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Amendment shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. 
 5.11
Loan Document. This Third Amendment is a “Loan Document” as defined and described in the Credit Agreement, and all of the terms and provisions of the Credit Agreement relating to Loan Documents shall apply hereto.
