indicated, all capitalized terms used herein and not otherwise defined shall have the respective meanings provided such terms in the Credit Agreement. 

W I T N E S S E T H: 

WHEREAS, the Borrower, the Lenders from time to time party thereto and BANK OF AMERICA, N.A., as Administrative Agent (in such capacity, the
“Administrative Agent”), Collateral Agent and Issuing Lender, are parties to a Credit Agreement, dated as of July 31, 2012 (as amended by the First Amendment to Credit Agreement, dated as of August 16, 2013, the Second
Amendment to Credit Agreement, dated as of May 7, 2014, the Third Amendment to Credit Agreement, dated as of July 13, 2016, and as otherwise heretofore amended, the “Credit Agreement”); 

WHEREAS, the Borrower has requested that (a) the Persons set forth on Schedule I hereto (the “New Refinancing Tranche B Term
Lenders”) make term loans (the “New Refinancing Tranche B Term Loans”) in an aggregate principal amount of $22,799,371.08 to the Borrower on the Fourth Amendment Effective Date (as defined below) and (b) the Exchanging
Lenders (as defined below) exchange their Existing Tranche B Term Loans (as defined below) for term loans of like aggregate principal amount (the “Exchanged Refinancing Tranche B Term Loans” and, together with the New Refinancing
Tranche B Term Loans, the “Refinancing Tranche B Term Loans”), in each case subject to the terms and conditions set forth herein; and 

WHEREAS, pursuant to Section 10.1(c) of the Credit Agreement, the Borrower, the Administrative Agent and the Refinancing Tranche B Term
Lenders (as defined below) agree to amend the Credit Agreement as set forth herein. 
 NOW, THEREFORE, in consideration of the foregoing,
and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 

SECTION ONE – REFINANCING TRANCHE B TERM LOANS. 

(a)    Subject to the terms and conditions set forth herein and in the Credit Agreement, each New Refinancing Tranche B
Term Lender severally agrees to make New Refinancing Tranche B Term Loans in Dollars to the Borrower on the Fourth Amendment Effective Date in an aggregate principal amount not to exceed the amount set forth opposite such New Refinancing Tranche B
Term Lender’s name on Schedule I hereto. Amounts borrowed under this Section 1(a) and repaid or prepaid may not be reborrowed. 

(b)    The proceeds of the New Refinancing Tranche B Term Loans shall be used solely to repay in full all Initial Tranche
B Term Loans outstanding under the Credit Agreement immediately prior to the effectiveness hereof (the “Existing Tranche B Term  







 
Loans”), other than the Existing Tranche B Term Loans of the Exchanging Lenders that are exchanged for Exchanged Refinancing Tranche B Term Loans and deemed repaid pursuant to
paragraph (d) below, and to pay related accrued and unpaid interest, fees and expenses. 
 (c)    Unless previously
terminated, the commitments of the New Refinancing Tranche B Term Lenders pursuant to Section 1(a) shall terminate upon the making of the New Refinancing Tranche B Term Loans on the Fourth Amendment Effective Date. 

(d)    Each lender holding Existing Tranche B Term Loans that executes and delivers a signature page to this Amendment and
indicates thereon its election of the “Cashless Settlement Option” (each such Lender, an “Exchanging Lender” and, together with the New Refinancing Tranche B Term Lenders, the “Refinancing Tranche B Term
Lenders”; each Tranche B Term Lender that does not so elect, a “Non-Exchanging Lender”) severally agrees, on the Fourth Amendment Effective Date and subject to the terms and
conditions set forth herein and in the Credit Agreement, to exchange all (or such lesser amount as the Administrative Agent may allocate to such Lender (any such Existing Tranche B Term Loans of such Lender not allocated for exchange pursuant
hereto, its “Non-Allocated Existing Tranche B Term Loans”)) of its Existing Tranche B Term Loans (the aggregate principal amount of Existing Tranche B Term Loans of such Lender so exchanged,
its “Exchanged Amount”) for Exchanged Refinancing Tranche B Term Loans (which Existing Tranche B Term Loans so exchanged shall thereafter be deemed repaid and canceled and no longer be outstanding) in an aggregate principal amount
equal to its Exchanged Amount. All accrued and unpaid interest on, and all other amounts owing in respect of, the Existing Tranche B Term Loans of each Exchanging Lender that are exchanged pursuant to this paragraph (d) (less the Exchanged
Amount) shall be repaid in full in cash on the Fourth Amendment Effective Date. 
 (e)    The Existing Tranche B Term
Loans of each Non-Exchanging Lender and the Non-Allocated Existing Tranche B Term Loans of each Exchanging Lender shall be repaid in full in cash on the Fourth Amendment
Effective Date, together with all accrued and unpaid interest on, and all other amounts owing in respect of, such Existing Tranche B Term Loans. 

(f)    Unless the context shall otherwise require, the New Refinancing Tranche B Term Lenders and the Exchanging Lenders
shall constitute “Tranche B Term Lenders”, “Term Lenders” and “Lenders” and the New Refinancing Tranche B Term Loans and Exchanged Refinancing Tranche B Term Loans shall constitute “Initial Tranche B Term
Loans”, “Tranche B Term Loans”, “Term Loans” and “Loans”, in each case for all purposes of the Credit Agreement (as amended hereby) and the other Loan Documents. For the avoidance of doubt, the New Refinancing
Tranche B Term Loans and the Exchanged Refinancing Tranche B Term Loans shall constitute a single Tranche under the Credit Agreement. 

SECTION TWO – CREDIT AGREEMENT AMENDMENTS. Subject to the satisfaction of the conditions set forth in Section Three hereof: 

(a)    The following defined term shall be added to Section 1.1 of the Credit Agreement in the appropriate
alphabetical order: 
 “Fourth Amendment Effective Date”: February 6, 2017. 

  
 2 








 (b)    The definition of “Applicable Margin” or “Applicable
Commitment Fee Rate” set forth in Section 1.1 of the Credit Agreement is hereby amended by replacing the percentages “1.75%” and “2.75%” in clause (ii) thereof with “1.25%” and “2.25%”,
respectively. 
 (c)    Section 2.3(b) of the Credit Agreement is hereby amended by (x) replacing “the last
Business Day of December, 2016” with “the last Business Day of June, 2017” and (y) replacing “Third Amendment Effective Date” with “Fourth Amendment Effective Date” in all three places where it appears. 

(d)    Section 2.11(b) of the Credit Agreement is hereby amended by replacing “Third Amendment Effective Date”

 SECTION SIX – SEVERABILITY. Any provision of this
Amendment which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 
 SECTION
SEVEN – CONTINUING EFFECT; NO OTHER WAIVERS OR AMENDMENTS. Except as expressly set forth herein, this Amendment shall not (i) constitute a substitution or novation, or a payment and reborrowing, or a termination, of the Obligations
outstanding under the Credit Agreement (other than with respect to the Existing Tranche B Term Loans) or instruments guaranteeing or securing the same, which shall remain in full force and effect, except as modified hereby or (ii) by
implication or otherwise limit, impair, constitute a waiver of, or otherwise affect the rights and remedies of the Lenders, the Administrative Agent or the Loan Parties under the Credit Agreement, as amended hereby, the Guarantee and Collateral
Agreement or any other Loan Document, and shall not alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement, as amended hereby, the Guarantee and Collateral
Agreement or any other Loan Document, all of which are ratified and affirmed in all respects and shall continue in full force and effect. Nothing herein shall be deemed to entitle any Loan Party to a consent to, or a waiver, amendment, modification
or other change of, any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement, as amended hereby, the Guarantee and Collateral Agreement or any other Loan Document in similar or different circumstances.
After the Fourth Amendment Effective Date, any reference in any Loan Document to the Credit Agreement shall mean the Credit Agreement, as amended hereby. This Amendment shall constitute a Loan Document for all purposes of the Credit Agreement, as
amended hereby, and the other Loan Documents.

parties to this Amendment on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Amendment by facsimile or

costs and expenses incurred in connection with this Amendment including, without limitation, the reasonable fees and disbursements and other charges of Cravath, Swaine & Moore LLP, counsel to the Administrative Agent. 

SECTION TEN – GOVERNING LAW. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AMENDMENT SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS TO THE EXTENT THAT THE SAME ARE NOT MANDATORILY APPLICABLE BY STATUTE AND THE APPLICATION OF THE LAWS OF ANOTHER
JURISDICTION WOULD BE REQUIRED THEREBY. The provisions of Sections 10.12 and 10.17 of the Credit Agreement are hereby incorporated by reference herein, mutatis mutandis. 

SECTION ELEVEN – TAX MATTERS. For purposes of determining withholding Taxes imposed under FATCA, from and after the Fourth
Amendment Effective Date, the Borrower and the Administrative Agent shall treat (and the Lenders hereby authorize the Administrative Agent to treat) the Loans as not qualifying as a “grandfathered obligation” within the meaning of Treasury
