WHEREAS, pursuant to Section 2.26(c) of the Credit Agreement, the Borrower may establish an additional Tranche of
Specified Refinancing Debt by, among other things, entering into this Amendment pursuant to the terms and conditions of the Credit Agreement with Term Lenders agreeing to provide such additional Tranche of Specified Refinancing Debt (each such Term

 WHEREAS, the Borrower has requested that the initial Term B-2 Lenders party hereto (the “Initial Term B-2 Lender”) convert all or a portion of their Term Loans to a new
Tranche of term loans; and 
 WHEREAS, each Initial Term B-2 Lender has indicated its willingness to convert the
amount of its Term Loans specified on its signature page to this Amendment into a new Tranche of term loans on the terms and subject to the conditions herein. 
 NOW, THEREFORE, in consideration of the premises and agreements, provisions and covenants herein contained, the parties hereto agree as follows: 

SECTION 1. TERM B-2 FACILITY. 
 1.1 Term B-2 Loans. Effective as of the Third Amendment Effective Date (as defined in Section 2 below), each Initial Term B-2 Lender hereby agrees to extend the maturity of its Term
Loans in an aggregate amount equal to the lesser of (a) the amount specified as the “Maximum Extension Amount” on such Initial Term B-2 Lender’s signature page to this Amendment or (b) the Maximum Extension Amount of such
Initial Term B-2 Lender reduced ratably with the Maximum Extension Amounts of all other Initial Term B-2 Lenders until the aggregate amount of all such extended Term Loans equals the Maximum Term B-2 Facility Amount. Each such extended Term Loan is
hereby deemed to be a “Term B-2 Loan” and all of the Term B-2 Loans shall constitute a new Tranche of Specified Refinancing Debt (the “Term B-2 Facility”) under Section 2.26 of the Credit Agreement. Pursuant to
Section 2.26 of the Credit Agreement, the Term B-2 Loans shall have the terms set forth in this Amendment and in the Credit Agreement (as amended by this Amendment). 







 1.2 Term B-1 Loans. The Term Loans of any Term Lenders that are not Initial
Term B-2 Lenders and the portion of Term Loans of Initial Term B-2 Lenders that are not converted to Term B-2 Loans pursuant to Section 1.1 above shall be deemed to be “Term B-1 Loans.” 

1.3 Applicable Margin. The Term B-2 Loans may from time to time be LIBO Rate Loans or Base Rate Loans, as determined by the
Borrower and notified to the Administrative Agent in accordance with Sections 2.13 of the Credit Agreement. The Applicable Margin with respect to the Term B-2 Loans shall mean a percentage per annum equal to (i) with respect to LIBO Rate Loans,
3.50% and (ii) with respect to Base Rate Loans, 2.50%. 
 1.4 Amortization and Maturity Date. The Term B-2
Loans of each Lender shall be payable in equal consecutive quarterly installments on the last Business Day of each of December, March, June and September, commencing on the last Business Day of March 2012, in an amount equal to one quarter of one
percent (0.25%) of the aggregate amount of Term B-2 Loans extended on the Third Amendment Effective Date (as adjusted to reflect any prepayments thereof (other than any Discounted Voluntary Prepayment)), with the remaining balance of Term B-2 Loans
payable on August 7, 2017 (the “Term B-2 Maturity Date”). 
 1.5 Mandatory Prepayments. The
Term B-2 Loans shall be subject to mandatory prepayments on the same basis as Term B-1 Loans as set forth in Section 2.12 of the Credit Agreement. Pursuant to Section 2.18(b) of the Credit Agreement, any such mandatory prepayment on
account of principal of and interest on the Term B-1 Loans and Term B-2 Loans pursuant to Section 2.12 shall be applied to the remaining installments of each term loan Tranche as directed by the Borrower; provided that each such
prepayment is applied ratably between each of the Term B-1 Facility and the Term B-2 Facility. 
 1.6 Optional
Prepayments. The Term B-2 Loans may be optionally prepaid on the same terms as Term B-1 Loans as set forth in Section 2.11 of the Credit Agreement. As set forth in Section 2.18(b) of the Credit Agreement, optional prepayments of
the Term B-1 Loans and any Term B-2 Loans shall be applied to the remaining installments of each Term Loan Tranche as specified by the Borrower; provided that any such prepayment of the Term B-2 Facility shall be applied ratably to the Term
B-1 Facility.
