QFC”), the parties acknowledge and agree as follows with respect to the resolution power of 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):

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 

  
 7 

 
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.

	2.	 Tranche B-6 Term Loans. Subject to the terms and
conditions set forth herein, each Tranche B-6 Lender severally agrees to exchange Existing Term Loans for Tranche B-6 Term Loans and/or make Tranche B-6 Term Loans to the Borrower in a single borrowing in Dollars on the Amendment No. 6 Effective Date.

Tranche B-6 Term Loans may be referred to as “Tranche B-6 Loans” solely for administrative and operational purposes of the Administrative Agent, and that such

 8 

	 	(b)	 Proposed Borrowing. This Agreement represents a request by the Borrower to borrow Tranche B-6 Term Loans from the Tranche B-6 Lenders as set forth on the applicable Notice of Borrowing to be delivered by the Borrower under the Credit Agreement.

  

	 	(c)	 New Lenders. Each New Lender (i) confirms that it has received a copy of the Credit Agreement and

to enter into this Agreement; (ii) agrees that it will, independently and without reliance upon the Administrative Agent, the Collateral Agent, or any other Lender and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action under the Credit Agreement; (iii) appoints and authorizes the Administrative Agent and the Collateral Agent to take such action as agent on its behalf and to
exercise such powers under the Credit Agreement and the other Loan Documents as are delegated to the Administrative Agent or the Collateral Agent, as the case may be, by the terms thereof, together with such powers as are reasonably incidental
thereto; and (iv) agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Credit Agreement are required to be performed by it as a Lender, as the case may be. Each New Lender acknowledges and
agrees that it shall become a “Lender” under, and for all purposes of, the Credit Agreement and the other Loan Documents, and shall be subject to and bound by the terms thereof, and shall have all rights of a Lender thereunder.

B-6 Term Loans under the Credit Agreement. Such exchange shall be effected by book entry in such manner, and with such supporting documentation, as may be reasonably determined by the Administrative Agent in
its sole discretion. It is acknowledged and agreed that each Converting Lender has agreed to accept as satisfaction in full of its right to receive payment on the outstanding amount of Existing Term Loans of such Converting Lender the conversion of
its Existing Term Loans into Tranche B-6 Term Loans in accordance herewith, in lieu of the prepayment amount that would otherwise be payable by the Borrower pursuant to the Credit Agreement in respect of the
outstanding amount of Existing Term Loans of such Converting Lender. Notwithstanding anything to the contrary herein, each Converting Lender hereby waives any break funding payments in respect of such Lender’s Existing Term Loans.

	12.	 Amendment, Modification and Waiver. This Agreement may not be amended, modified or waived except

	13.	 Integration. This Agreement, the other Loan Documents and any separate letter agreements with
respect to fees payable to the Lead Arranger and/or the Administrative Agent or the syndication of the Tranche B-6 Term Loans and commitments related thereto constitute the entire contract among the parties
relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement shall not constitute a novation of any amount owing under the Credit
Agreement and all amounts owing in respect of principal, interest, fees and other amounts pursuant to the Credit Agreement and the other Loan Documents shall, to the extent not paid or exchanged on or prior to the Amendment No. 6 Effective
Date, continue to be owing under the Credit Agreement or such other Loan Documents until paid in accordance therewith.

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 Agreement by telecopier shall be effective
as delivery of a manually executed counterpart of this Agreement. 

  

	17.	 Loan Document. On and after the Amendment No. 6 Effective Date, this Agreement shall

Section 12 above).
