WITNESSETH

WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (as supplemented, the “Indenture”), dated as of June 16, 2010 providing for the issuance of 10% Senior Notes due 2018 (the “Notes”), as amended by that First Supplemental Indenture dated as of June 16, 2010, by and among the Company, the other Guarantors and the Trustee;

WHEREAS, on October 8, 2010, the Company acquired 100% of the outstanding capital stock of the Guaranteeing Subsidiary, at which time the Guaranteeing Subsidiary became a Domestic Subsidiary of the Company;

WHEREAS, the Guaranteeing Subsidiary guarantees payment by the Company of Indebtedness under the Credit Agreement;

WHEREAS, in light of the foregoing, Section 4.16 of the Indenture requires that the Guaranteeing Subsidiary execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s obligations under the Notes and the Indenture on the terms and conditions set forth herein and under the Indenture (the “Note Guarantee”);

WHEREAS, pursuant to Section 9.01(8) of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture; and

WHEREAS, all things necessary to make this Supplemental Indenture a valid indenture and agreement according to its terms have been done.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary, the Company, the other Guarantors 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.

(a) The Guaranteeing Subsidiary hereby becomes a party to the Indenture as a Guarantor and as such will have all of the rights and be subject to all of the obligations and agreements of a Guarantor under the Indenture, effective upon the execution and delivery of this Supplemental Indenture.

(b) 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.

3. NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of the Company or any Guarantor (including the Guaranteeing Subsidiary), as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, this Indenture, the Note Guarantees 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. The waiver may not be effective to waive liabilities under the federal securities laws.

8. BENEFITS ACKNOWLEDGED. The Guaranteeing Subsidiary’s Guarantee is subject to the terms and conditions in the Indenture. The Guaranteeing Subsidiary acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Indenture and this Supplemental Indenture and that the guarantee and waivers made by it pursuant to this Guarantee are knowingly made in contemplation of such benefits.
