Lender or Defaulting Lender shall be deemed to have executed and delivered such Assignment and Assumption without any action on the part of the Non-Consenting Lender or Defaulting Lender.” 

SECTION II. INCREASED TERM LOAN 

2.1    Increased Term Loan Commitment. 

(a) The lender providing the Increased Term Loan (the “Increase Lender”) party hereto hereby agrees to commit to provide the
Increased Term Loan as set forth on Schedule A annexed hereto on the First Amendment Effective Date, on the terms and subject to the terms and conditions set forth herein and in the Credit Agreement. 

(b) The Increase Lender (i) confirms that it has received a copy of the Credit 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 in order to make its own credit analysis and decision to enter into this Amendment and make the Increased Term Loan;
(ii) agrees that it will, independently and without reliance upon the Administrative Agent or any other Lender or agent 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 or the other applicable Loan Documents, including this Amendment; (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 and the Collateral Agent, as the case may be, by the terms thereof, together with such powers as are
reasonably incidental thereto; and (iv) acknowledges and agrees that upon the First Amendment Effective Date, the Increase Lender shall be 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 the rights of a Lender and an Incremental Lender thereunder. 

(c) The Increase Lender agrees, subject to the terms and conditions of this Amendment and the Credit Agreement, to make the Increased Term
Loan to the Borrower on the First Amendment Effective Date in an aggregate principal amount not to exceed the Increased Term Loan amount as set forth on Schedule A annexed hereto. The commitment of the Increase Lender to make the Increased Term Loan
hereunder shall be automatically and permanently terminated on the First Amendment Effective Date (after the funding of the Increased Term Loan). To the extent repaid, the Increased Term Loan may not be reborrowed. 

(d) This Amendment shall constitute (i) the notice required to be delivered by the Borrower to the Administrative Agent pursuant to
Section 2.13(a) of the Credit Agreement, (ii) an amendment contemplated by Section 2.13(d) of the Credit Agreement and (iii) a joinder contemplated by
Section 2.13(c) of the Credit Agreement. As of the First Amendment Effective Date, after giving effect to the incurrence of the Increased Term Loan, the aggregate principal amount of Term Loans outstanding pursuant to the
Credit Agreement shall be $920,875,000.00. 
 2.2    Increased Term Loan. 

Notwithstanding any provision to the contrary herein or in the Credit Agreement, the terms of the Increased Term Loan (including, without
limitation, the Applicable Rate and the principal payment 

  
 4 

 
terms applicable thereto) shall, except to the extent of the Incremental Fee, be the same as the terms of the Term Loans outstanding immediately after giving effect to this Amendment, and the
Increased Term Loan shall be a Term Loan for all purposes of this Amendment and the Credit Agreement and shall constitute one tranche with, and be the same class as, the Term Loans made pursuant to Section 2.01 of the
Credit Agreement. Following the First Amendment Effective Date and the funding of the Increased Term Loan, each reference in the Credit Agreement to “Term Commitment” shall include the commitment to make the Increased Term Loan hereunder,
each reference to “Term Loans” shall include the Increased Term Loan and each reference to “Lender” shall include the Increase Lender hereunder, in each case, unless the context shall require otherwise. Each of the parties hereto
hereby agrees that the Administrative Agent may take any and all action as may be reasonably necessary to ensure that the Increased Term Loan, when originally made, is a Term Loan for all purposes under the Loan Documents and is included in each
Borrowing of outstanding Term Loans on a pro rata basis. This may be accomplished at the discretion of the Administrative Agent by allocating a portion of the Increased Term Loan to each outstanding Eurodollar Rate Loan that is a Term Loan of the
same class on a pro rata basis, even though as a result thereof the Increased Term Loan may effectively have a shorter Interest Period than the Term Loans included in the Borrowing of which it is a part (and notwithstanding any other provision of
the Credit Agreement that would prohibit such initial Interest Period). The Increased Term Loan shall not accrue interest for any period prior to the First Amendment Effective Date and the Borrower shall not be required to pay interest on the
Increased Term Loan pursuant to Section 2.06 of the Credit Agreement for any period prior to the First Amendment Effective Date. 

2.3    Proposed Borrowing. 

This Amendment represents the Borrower’s request to borrow the Increased Term Loan from the Increase Lender as follows (the
“Proposed Borrowing”): 
 (i) Class of Proposed Borrowing: Term Loans. 

(ii) Aggregate principal amount of Proposed Borrowing: $100,000,000. 

(iii) Date of Proposed Borrowing: February 9, 2017. 

(iv) Type of Borrowing: Eurodollar Rate Loan. 

(v) Interest Period: Interest Period ending March 23, 2017, consistent with the Interest Period of the outstanding Term
Loans. 
 2.4    Credit Agreement Governs. 

Except as set forth in this Amendment, the Increased Term Loan shall otherwise be subject to the provisions of the Credit Agreement and the
other Loan Documents. 
 2.5    Use of Proceeds. 

The proceeds of the Increased Term Loan shall be used solely for general corporate purposes, including consummation of either Acquisition and
to pay certain fees, charges, premiums, expenses and other transaction costs incurred in connection with this Amendment or either Acquisition. 

2.6    Notice. 

For purposes of the Credit Agreement, the initial notice address of the Increase Lender shall be as specified by it to the Administrative
Agent. 

  
 5 

 2.7    Recordation of New Loans. 

Upon execution and delivery hereof, and the funding of the Increased Term Loan, the Administrative Agent will record the Increased Term Loan
made by the Increase Lender in the Register as “Term Loans” for all purposes of the Credit Agreement and constituting the same class as the Term Loans made pursuant to Section 2.01 of the Credit Agreement. 

2.8    Increased Term Loan Effectiveness.

become effective immediately after the effectiveness of the amendments to the Credit Agreement specified in Section I of this Amendment on the First Amendment Effective Date.

(a) Power and Authority. Each of the Borrower and each Guarantor has all requisite power and authority to execute,
deliver and perform its obligations under this Amendment.

performance by each of the Borrower and each Guarantor of this Amendment, and the consummation of the transactions contemplated herein, are within such Loan Party’s corporate or other powers, have been duly authorized by all necessary corporate
or other organizational action, and do not (a) contravene the terms of any of such Person’s Organization Documents; (b) conflict with or result in any breach or contravention of, or the creation of any Lien under (other than as

accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, examinership, receivership, moratorium or other laws affecting creditors’ rights generally and by general principles of equity.

economic or industry nature) to any Agent or any Lender in connection with the transactions contemplated hereby and the negotiation of this Amendment or delivered hereunder (as modified or supplemented by other information so furnished), when taken
as a whole, contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein (when taken as a whole), in the light of the circumstances under which they were made, not materially misleading;
provided that, with respect to projected and pro forma financial information, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time of preparation and
delivery; it being understood that such projections may vary from actual results and that such variances may be material. 
 SECTION
V.    MISCELLANEOUS

The Borrower hereby confirms that the indemnification provisions set forth in Section 10.05 of the Credit Agreement
shall apply to this Amendment and such losses, claims, damages, liabilities, costs and expenses (as more fully set forth therein as applicable) which may arise out of or in connection with any actual or prospective claim, litigation, investigation
or proceeding in any way relating to, arising out of, in connection with or by reason of any of the following, whether based on contract, tort or any other theory, the execution, delivery, enforcement, performance or administration of the Amendment

 5 

 
agreement contained in the Credit Agreement or any other Loan Document is hereby ratified and reaffirmed in all respects and shall continue in full force and effect as modified by this Amendment
and nothing herein can or may be construed as a novation thereof. This Amendment shall constitute a Loan Document for purposes of the Credit Agreement and from and after the Second Amendment Effective Date, all references to the Credit Agreement in
any Loan Document and all references in the Credit Agreement to ‘‘this Agreement”, “hereunder’’, “hereof’ or words of like import referring to the Credit Agreement, shall, unless expressly provided otherwise,
refer to the Credit Agreement as modified by this Amendment.

accordance therewith sell its existing Term Loans as specified in the Master Assignment and Assumption. In the event that such Cash Roll Lender does not execute the Master Assignment and Assumption, such Cash Roll Lender shall have been deemed to

jurisdiction, waiver of venue, service of process, and waiver of jury trial are hereby incorporated by reference herein, mutatis mutandis. 

5.9    Severability. 

  
 6 

 Any term or provision of this Amendment 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 Amendment or affecting the validity or enforceability of any of
the terms or provisions of this Amendment in any other jurisdiction. If any provision of this Amendment is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as would be enforceable.

This Amendment 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. Delivery of an executed counterpart of a signature page of this Amendment by telecopy or other electronic imaging (including in .pdf or .tif format) means shall be effective as delivery of a manually executed counterpart of this
Amendment
