WITNESSETH

 

WHEREAS, the Issuer has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of April 6, 2010 providing for the issuance of 10⅜% Senior Notes due 2018 (the “Notes”);

 

WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuer’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and

 

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

 

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

 

1.           Capitalized Terms.  Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

 

2.           Agreement to Guarantee.  The Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article 10 thereof.

 

4.           No Recourse Against Others.  No director, officer, employee, stockholder, general or limited partner or incorporator of the Issuers or any Guarantor, as such, shall have any liability for any obligations of the Issuers or the Guarantors under the Notes, this Indenture, the Note Guarantees or the note documents or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.
