Each Cash Roll Lender hereby consents and agrees (subject to the effectiveness of the assignment referred to in the following clause (ii)) to (i) this Amendment, (ii) immediately upon the effectiveness of this Amendment, sell the entire principal amount of its existing Term Loans via an assignment on the Third Amendment Effective Date pursuant to an Assignment and Assumption (or Master Assignment and Assumption) and (iii) commit to repurchase a like amount (or, if so determined by the Arranger and the Borrower, a lesser amount identified by the Arranger) of the repriced Term Loans via an assignment after the Third Amendment Effective Date. By executing a signature page hereto and consenting to this Amendment via a cash settlement, each such Lender under the Credit Agreement shall be deemed to have executed a counterpart to the Master Assignment and Assumption to give effect, solely upon the consent and acceptance by the Arranger, to the assignment described in clause (ii) of the immediately preceding sentence.

Section and Subsection 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 or be given any substantive effect.

THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

The provisions of Sections 10.15(b), (c) and (d) and 10.16 of the Credit Agreement pertaining to consent to jurisdiction, waiver of venue, service of process, and waiver of jury trial are hereby incorporated by reference herein, mutatis mutandis.

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
