ARTICLE II

MISCELLANEOUS

(a) This First Amendment, and each of the amendments contained herein, shall become effective on the date (the “First Amendment Effective Date”) when the Administrative Agent shall have received counterparts of this First Amendment duly executed by Holdings, the Borrower, the other Loan Parties and the Administrative Agent and duly consented to by the Required Lenders.

(b) On the First Amendment Effective Date, the Credit Agreement will be automatically amended to reflect the amendments thereto provided for in this First Amendment. The rights and obligations of the parties hereto shall be governed (i) prior to the First Amendment Effective Date, by the Credit Agreement and (ii) on and after the First Amendment Effective Date, by the Credit Agreement as amended by this First Amendment. Once the First Amendment Effective Date has occurred, all references to the Credit

Agreement in any document, instrument, agreement, or writing shall be deemed to refer to the Credit Agreement as amended by this First Amendment. Except as specifically amended by this First Amendment, the Credit Agreement shall remain in full force and effect and the Credit Agreement and all obligations of the Loan Parties thereunder, as amended by this First Amendment, are hereby ratified and affirmed in all respects.

(c) Other than as specifically provided herein, this First Amendment shall not operate as a waiver or amendment of any right, power or privilege of the Administrative Agent or any Lender under the Credit Agreement or any other Finance Document or of any other term or condition of the Credit Agreement or any other Finance Document, nor shall the entering into of this First Amendment preclude the Administrative Agent and/or any Lender from refusing to enter into any further waivers or amendments with respect thereto. This First Amendment is not intended by any of the parties hereto to be interpreted as a course of dealing which would in any way impair the rights or remedies of the Administrative Agent or any Lender except as expressly stated herein, and no Lender shall have any obligation to extend credit to the Borrower other than pursuant to the strict terms of the Credit Agreement and the other Finance Documents, as amended or supplemented to date (including by means of this First Amendment).

(d) The Loan Parties have all requisite corporate (or similar organizational) power and authority to enter into this First Amendment and to carry out the transactions contemplated by, and perform their obligations under, this First Amendment (and the Credit Agreement as amended by this First Amendment). The execution, delivery and performance of this First Amendment (and the Credit Agreement as amended by this First Amendment) by each Loan Party have been duly authorized by all necessary corporate (or similar organizational) action. This First Amendment has been duly executed and delivered by each Loan Party. This First Amendment constitutes legal, valid and binding obligations of the Loan Parties enforceable in accordance with their terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing.

(e) This First Amendment may be executed by the parties hereto in several counterparts, each of which shall be deemed to be an original and all of which shall constitute together but one and the same agreement. A counterpart hereof executed and delivered by facsimile or pdf or other similar electronic transmission shall be effective as an original.

(f) This First Amendment and the rights and obligations of the parties hereunder shall be governed by and construed and interpreted in accordance with the internal laws of the State of New York (including, without limitation, Section 5-1401 of the General Obligations Law of the State of New York).
