NOW, THEREFORE, IT IS AGREED:

1. Amended and Restated Guarantee and Collateral Agreement. By executing and delivering this Assumption Agreement, the Additional Grantor, as provided in Section 9.14 of the Amended and Restated Guarantee and Collateral Agreement, hereby becomes a party to the Amended and Restated Guarantee and Collateral Agreement as a Grantor and a Guarantor thereunder with the same force and effect as if originally named therein as a Grantor and a Guarantor and, without limiting the generality of the foregoing, hereby expressly assumes all obligations and liabilities of a Grantor and a Guarantor thereunder. The Additional Grantor hereby assigns and transfers to the Administrative Agent, and hereby grants to the Administrative Agent, for the ratable benefit of the Secured Parties, a security interest in the Collateral (as defined in the Amended and Restated Guarantee and Collateral Agreement), as collateral security for the prompt and complete payment and performance when due (whether at stated maturity, by acceleration or otherwise) of the Obligations (as defined in the Amended and Restated Guarantee and Collateral Agreement). The information set forth in Annex 1-A hereto is hereby added to the information set forth in the Schedules to the Amended and Restated Guarantee and Collateral Agreement. The Additional Grantor hereby represents and warrants that, as to itself, each of the representations and warranties contained in Section 5 of the Amended and Restated Guarantee and Collateral Agreement is true and correct on and as the date hereof (after giving effect to this Assumption Agreement) as if made on and as of such date.

2. Execution of Financing Statements. Pursuant to any applicable law, the Additional Grantor authorizes the Administrative Agent to file or record financing statements, continuation statements, and amendments to financing statements in any jurisdictions and with any filing offices as the Administrative Agent may determine are necessary or advisable to perfect the security interest granted to the Administrative Agent in connection herewith with respect to the Collateral without the signature of

such Grantor, to the extent permitted by law, in such form as the Administrative Agent determines appropriate to perfect the security interests of the Administrative Agent under this Assumption Agreement and the Amended and Restated Guarantee and Collateral Agreement. Such financing statements may describe the Collateral in the same manner as described in this Assumption Agreement and the Amended and Restated Guarantee and Collateral Agreement or may contain an indication or description of Collateral that describes such property in any other manner as the Administrative Agent may determine, in its sole discretion, is necessary, advisable or prudent to ensure the perfection of the security interest in the Collateral granted to the Administrative Agent in connection with this Assumption Agreement and the Amended and Restated Guarantee and Collateral Agreement, including, without limitation, describing such property as “all assets, whether now owned or hereafter acquired” or “all personal property, whether now owned or hereafter acquired.” The Additional Grantor hereby ratifies and authorizes the filing by the Administrative Agent of any financing statement with respect to the Collateral made prior to the date hereof.
