The Loan Parties are required by Section 7.12 of the Credit Agreement to cause the Material Subsidiary to become a “Guarantor” thereunder. Accordingly, the Material Subsidiary hereby agrees as follows with the Administrative Agent, for the benefit of the Lenders:

1.    The Material Subsidiary hereby acknowledges, agrees and confirms that, by its execution of this Agreement, the Material Subsidiary will be deemed to be a party to the Credit Agreement and a “Guarantor” for all purposes of the Credit Agreement, and shall have all of the obligations of a Guarantor thereunder as if it had executed the Credit Agreement. The Material Subsidiary hereby ratifies, as of the date hereof, and agrees to be bound by, all of the terms, provisions and conditions applicable to the Guarantors contained in the Credit Agreement. Without limiting the generality of the foregoing terms of this paragraph 1, the Material Subsidiary hereby jointly and severally together with the other Guarantors, guarantees to each Lender, each Swap Bank, each Treasury Management Bank and the Administrative Agent, as provided in Article IV of the Credit Agreement, the prompt payment and performance of the Obligations in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration or otherwise) strictly in accordance with the terms thereof.

2.    The Subsidiary hereby represents and warrants to the Administrative Agent that the Material Subsidiary’s exact legal name and state of formation are as set forth on the signature pages hereto.

3.    The address of the Material Subsidiary for purposes of all notices and other communications is the address designated for all Loan Parties on Schedule 11.02 to the Credit Agreement or such other address as the Material Subsidiary may from time to time notify the Administrative Agent in writing.

4.    The Material Subsidiary hereby waives acceptance by the Administrative Agent and the Lenders of the guaranty by the Material Subsidiary under Article IV of the Credit Agreement upon the execution of this Agreement by the Material Subsidiary.

5.    This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic imaging means (e.g. “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Agreement.

6.    THIS AGREEMENT AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSE OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.
