WHEREAS, the Indentures provide that under certain circumstances the Guaranteeing Entities shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Entities shall unconditionally guarantee all of the Issuers’ obligations under the Notes and the Indentures on the terms and conditions set forth herein (the “Note Guarantee”); and

WHEREAS, pursuant to Section 9.01 of the Indentures, the Trustee is authorized to execute and deliver this Fifth 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 Entities 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 Indentures.

2. AGREEMENT TO GUARANTEE. The Guaranteeing Entities hereby agree to provide an unconditional Guarantee on the terms and subject to the conditions set forth in each Note Guarantee and in the Indentures including but not limited to Article 10 thereof.

3. NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of the Issuers or any Subsidiary Guarantor, as such, will have any liability for any obligations of the Company or any Subsidiary Guarantors under the Notes, the Indentures, 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.

THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS FIFTH SUPPLEMENTAL INDENTURE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.
