below. 
 WHEREAS the Borrower, the Guarantor Subsidiaries and the Administrative Agent, inter alia, have entered into Amendment
No. 1 to Credit and Guaranty Agreement dated as of June 1, 2007 (the “Amendment”), which amends the Credit and Guaranty Agreement dated as of May 9, 2007 (the “Credit Agreement”), among the Borrower,
the Guarantor Subsidiaries, the Lenders party thereto, the Administrative Agent and Credit Suisse Securities (USA) LLC, as Syndication Agent, as in effect on the date hereof (the Credit Agreement, as so amended by the Amendment, the “Amended
Credit Agreement”); 
 WHEREAS in order to induce the Tack-on Lenders (such term and each other capitalized term used but not
defined herein having the meaning assigned to such terms in the Amended Credit Agreement) to make the Tack-on Loans to the Borrower pursuant to the Amendment, each of the Reaffirming Parties is willing to execute and deliver this Agreement;

 WHEREAS each of the Reaffirming Parties is party to one or more of the Collateral Documents; 
 WHEREAS each Reaffirming Party expects to realize, or has realized, substantial direct and indirect benefits as a result of the Amendment becoming

 WHEREAS the execution and delivery of this Agreement is a
condition precedent to the respective obligations of the Tack-on Lenders to make the Tack-on Loans contemplated by the Amendment. 
 NOW,
THEREFORE, in consideration of the mutual agreements herein contained and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, and subject to the conditions set forth herein, the parties hereto hereby
agree as follows:

Reaffirming Parties (i) hereby consents to the Amendment and the transactions contemplated thereby (including the making of the Tack-on Loans), (ii) hereby confirms its guarantees, pledges, grants of security interests and other
agreements, as applicable, under each of the Credit Documents to which it is a party and (iii) agrees that notwithstanding the effectiveness of the Amendment and the consummation of the transactions contemplated thereby, such guarantees,
pledges, grants of security interests and other agreements shall continue to be in full force and effect and shall accrue to the benefit of the Lenders under the Amended Credit Agreement. Each of the Reaffirming Parties further agrees to take any
action that may be required or that is reasonably requested by the Administrative Agent to ensure compliance by the Borrower with Section 5.13 of the Amended Credit Agreement and hereby reaffirms its obligations under each similar provision of
each Credit Document to which it is a party. 
 (b) Each of the Reaffirming Parties party to each of the Credit Documents securing the
Obligations of the Borrower hereby confirms and agrees that (i) the Tack-on Loans constitute “Obligations” under such documents and (ii) the Existing Term Loans have constituted and continue to constitute “Obligations”
under such documents. 
 SECTION 1.02. Amendment. On and after the effectiveness of the Amendment, (a) each reference in
each Collateral Document to the “Credit Agreement”, “thereunder”, “thereof” or words of like import shall mean and be a reference to the Amended Credit Agreement as such agreement may be amended, modified or
supplemented and in effect from time to time and (b) the definition of any term defined in any Collateral Document by reference to the terms defined in the Existing Credit Agreement shall be amended to be defined by reference to the applicable
defined term in the Amended Credit Agreement, as the same may be amended, modified or supplemented and in effect from time to time. 
 ARTICLE II. 
 Representations and Warranties 
 Each Reaffirming Party hereby represents and warrants, which representations and warranties shall survive execution and delivery of this Agreement, as

or by instruments executed concurrently herewith. Nothing implied in this Agreement, the

Documents. Each of the Existing Credit Agreement and the Collateral Documents shall remain in full force and effect, until (as applicable) and except to any extent modified hereby or by the Amendment or in connection herewith and therewith.
