RECITALS OF THE COMPANY

The Company and the Trustee have entered into the Original Indenture, providing for the issuance by the Company of its 10.875% Senior Notes due 2016 (the “Securities”).

The Company and the Surviving Entity have entered into an Agreement and Plan of Merger, dated April 30, 2012, which contemplates the filing of a certificate of merger with the Secretary of State of the State of Delaware providing for the merger (the “Merger”) of the Company with and into the Surviving Entity, with the Surviving Entity continuing its corporate existence under the laws of the State of Delaware as the surviving company of the Merger.

Pursuant to Section 8.01 of the Original Indenture, the Company may merge with and into another Person, provided that, among other things, (i) the Person formed by any merger with and into the Company (if other than the Company) expressly assumes by a supplemental indenture executed and delivered to the Trustee all the obligations of the Company under the Indenture and the Securities and (ii) the Indenture, as so supplemented, and the Securities remain in full force and effect.

Pursuant to Section 9.01 of the Original Indenture, the Indenture and the Securities may be amended or supplemented without the consent of any Holder to provide for the assumption of the Company’s obligations to Holders in the case of a merger consummated pursuant to Article VIII of the Indenture.

Pursuant to Section 9.01 of the Original Indenture, the Company, Holdings, the Subsidiary Guarantors and the Trustee may make such amendment, waiver or supplement so long as such amendment, waiver or supplement does not adversely affect the rights of Holders, subject to the fulfillment of certain other conditions set forth therein.

The amendments contained herein do not adversely affect the rights of Holders.

The Surviving Entity, the Company, Holdings, the Subsidiary Guarantors and the Trustee wish to supplement the Original Indenture so that the Surviving Entity expressly assumes all the obligations of the Company under the Original Indenture and the Securities.

The Surviving Entity desires and has requested that the Trustee join in the execution of this First Supplemental Indenture for the purpose of evidencing such assumption by the Surviving Entity.

The entry into this First Supplemental Indenture by the Surviving Entity, the Company, Holdings, the Subsidiary Guarantors and the Trustee is in all respects authorized by the provisions of the Original Indenture.
