RECITALS: 
 WHEREAS,
reference is hereby made to the Loan Agreement, dated as of April 29, 2016, as amended by Amendment No. 1, dated as of August 17, 2016 and Amendment No. 2, dated as of September 22, 2016 (as further amended, restated,
extended, supplemented or otherwise modified in writing from time to time, the “Loan Agreement”), among the Borrower, each lender from time to time party thereto, JPMorgan Chase Bank, N.A., as Administrative Agent and the other
parties thereto (capitalized terms used but not defined herein having the meaning provided in the Loan Agreement (as amended by Amendment No. 3)); 

WHEREAS, subject to the terms and conditions of the Loan Agreement, the Borrower may establish the Additional U.S. Term B-2 Commitment with existing U.S. Term B-1 Lenders and/or Additional U.S. Term B-2 Lenders; and 

WHEREAS, subject to the terms and conditions of Amendment No. 3, Additional U.S. Term B-2 Lenders
shall become Lenders pursuant to one or more Joinders (as defined in Amendment No. 3); 
 NOW, THEREFORE, in consideration of the
premises and agreements, provisions and covenants herein contained, the parties hereto agree as follows: 
 Each Additional U.S. Term B-2 Lender hereby agrees to provide the Additional U.S. Term B-2 Commitment set forth on its signature page hereto pursuant to and in accordance with Section 2.1(d) of the
Loan Agreement. The Additional U.S. Term B-2 Commitment provided pursuant to this Agreement shall be subject to all of the terms in the Loan Agreement and to the conditions set forth in the Loan Agreement, and
shall be entitled to all the benefits afforded by the Loan Agreement and the other Loan Documents, and shall, without limiting the foregoing, benefit equally and ratably from the Guaranty and security interests created by the Collateral Documents.

 Each Additional U.S. Term B-2 Lender, the Borrower and the Administrative Agent acknowledge and
agree that the Additional U.S. Term B-2 Commitment provided pursuant to this Agreement shall constitute Additional U.S. Term B-2 Commitments for all purposes of the Loan
Agreement and the other applicable Loan Documents. Each Additional U.S. Term B-2 Lender hereby agrees to make an Additional U.S. Term B-2 Loan to the Borrower in an








 
amount equal to its Additional U.S. Term B-2 Commitment on the Amendment No. 3 Effective Date in accordance with Section 2.01(f) of the Loan
Agreement. 
 Each Additional U.S. Term B-2 Lender (i) confirms that it has received a copy of
the Loan Agreement and the other Loan Documents, together with copies of the financial statements referred to therein and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into
this Agreement; (ii) agrees that it will, independently and without reliance upon the Administrative Agent, the Joint Lead Arrangers or any other Additional U.S. Term B-2 Lender 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 Loan Agreement; (iii) appoints and authorizes the Administrative Agent to take
such action as agent on its behalf and to exercise such powers and discretion under the Loan Agreement and the other Loan Documents as are delegated to the Administrative Agent by the terms thereof, together with such powers and discretion 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 Loan Agreement are required to be performed by it as a Lender. 

Upon (i) the execution of a counterpart of this Agreement by each Additional U.S. Term B-2
Lender, the Administrative Agent and the Borrower and (ii) the delivery to the Administrative Agent of a fully executed counterpart (including by way of telecopy or other electronic transmission) hereof, each of the undersigned Additional U.S.
Term B-2 Lenders shall become Lenders under the Loan Agreement and shall have the respective Additional U.S. Term B-2 Commitment set forth on its signature page hereto,
effective as of the Amendment No. 3 Effective Date.

Lender may be required to deliver to the Administrative Agent pursuant to Section 10.1 of the Loan Agreement. 
 This Agreement may
not be amended, modified or waived except by an instrument or instruments in writing signed and delivered on behalf of each of the parties hereto. 

This Agreement, the Loan Agreement and the other Loan Documents constitute the entire agreement among the parties with respect to the subject
matter hereof and thereof and supersede all other prior agreements and understandings, both written and verbal, among the parties or any of them with respect to the subject matter hereof. 

THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK. 

  
 B-2 








 Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction
shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of
the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as would be enforceable. 

This Agreement may be executed in counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and
the same agreement.
