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 Amendment; 

(b) agrees that it will, independently and without reliance upon the Administrative Agents or any other Lender or Agent and

(c) appoints and authorizes the Administrative Agents and Collateral Agents 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 Agents and the Collateral Agents, as the case may be, by the terms thereof, together with such powers as are reasonably incidental
thereto; and 
 (d) solely with respect to each Commitment Increase Lender providing a new Revolving Credit Commitment
hereunder, acknowledges and agrees that, upon its execution of this Amendment, such Commitment Increase Lender shall automatically and without further action 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 perform all the obligations of and shall have all rights of a Lender thereunder. 

2.3 Each Commitment Increase Lender hereby agrees to make its new Revolving Credit Commitment or increased Revolving Credit Commitment, as the
case may be, on the following terms and conditions:

Revolving Credit Loans provided in connection with the Commitment Increase shall be identical to the Revolving Credit Commitments and Revolving Credit Loans under the Credit Agreement as in effect immediately prior to giving effect to this

notice to, or filing with, any Governmental Authority or any other Person is necessary or required in connection with the execution, delivery or performance by, or enforcement against, any Loan Party of this Amendment, except for (i) the

generally and by general principles of equity. 
 3.4 No Default or Event of Default has occurred and is continuing under the Credit
Agreement or any other Loan Document or will occur and be continuing as a result of the execution, delivery and performance of this Amendment or the consummation of any of the other actions contemplated hereby.

Credit Agreement shall have been satisfied on and as of the date hereof. 
 4.3 Breakage Payments. The Borrowers shall have made any
breakage payments required by Section 3.05 of the Credit Agreement in connection with any adjustment of Revolving Credit Loans pursuant to Section 2.16(e) of the Credit Agreement. 

4.4 Legal Opinion. The U.S. Administrative Agent shall have received an opinion of Paul, Weiss, Rifkind, Wharton & Garrison
LLP, as special counsel to the Loan Parties, as to such matters concerning the Loan Parties and this Amendment as the U.S. Administrative Agent may reasonably request. 

4.5 Fees. The Borrowers shall have paid to the Administrative Agent and the Lenders such fees as shall have been separately agreed upon
in writing. 
 The funding by each Commitment Increase Lender of any portion of its Commitment will be deemed irrevocable evidence of the satisfaction of
the conditions set forth in this Section 4. 
 5. Reference to and Effect Upon the Credit Agreement and other Loan Documents.

 5.1 Full Force and Effect. Each Loan Party hereby consents to this Amendment and hereby confirms and agrees that (a) each Loan
Document to which it is a party is, and shall continue to be, in full force and effect and each is hereby ratified and confirmed, and (b) the Liens granted by such Loan Party on all Collateral of such Loan Party continue to secure the payment
of all of the U.S. Obligations and/or Canadian Obligations (as applicable). 
 5.2 No Waiver. The execution, delivery and effect of
this Amendment shall be limited precisely as written and shall not be deemed to (a) be a consent to any waiver of any term or condition or, except as specifically provided herein, to any amendment or modification of any term or condition of the
Credit Agreement or any other Loan Document or (b) prejudice any right, power or remedy which any Agent or any Lender now has or may have in the future under or in connection with the Credit Agreement or any other Loan Document. 

5.3 Certain Terms. Each reference in the Credit Agreement to “this Agreement”, “hereunder”, “hereof”,
“herein” or any other word or words of similar import shall mean and be a reference to the Credit Agreement as amended hereby, and each reference in any other Loan Document to the Credit Agreement or any word or words of similar import
shall be and mean a reference to the Credit Agreement as amended hereby. 
 6. Counterparts. This Amendment may be executed in any
number of counterparts, each of which when so executed shall be deemed an original but all such counterparts shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Amendment by electronic
transmission shall be as effective as delivery of a manually executed counterpart signature page to this Amendment. 

  
 4 

 7. Severability. If any provision of this Amendment is held to be illegal, invalid or
unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Amendment shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal,
invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction. 
 8. Successors. The provisions of this Amendment shall
be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.  
 9. GOVERNING
LAW. THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 
 10. Costs and
Expenses. As provided in Section 10.04 of the Credit Agreement, the Borrowers shall pay the reasonable out-of-pocket expenses incurred by the Administrative Agents in connection with the preparation, execution and delivery of this
Amendment. 
 11. Headings. Section headings in this Amendment are included herein for convenience of reference only and shall not
constitute a part of this Amendment for any other purpose. 
 12. Certain U.S. Federal Income Tax Matters. The Borrowers have
determined that this Amendment does not result in a significant modification of the Revolving Credit Commitments for U.S. federal income tax purposes and accordingly, the Revolving Credit Commitments continue to be “grandfathered
obligations” for purposes of FATCA. “FATCA”, for purposes of this Section 12, means Section 1471 through 1474 of the Code (or any amended or successor version that is substantively comparable) or any Treasury
regulations promulgated thereunder.
