WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of April 14, 2011 providing for the issuance of 7.50% Senior Notes due 2021 (the “Notes”);
WHEREAS, the Indenture provides that under certain circumstances the Guarantying Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guarantying Subsidiary shall unconditionally guarantee all of the Company's Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Guaranty”); 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 Guarantying 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 GUARANTY.  The Guarantying Subsidiary hereby agrees to provide, and does hereby provide, an unconditional Guaranty on the terms and subject to the conditions set forth in the Guaranty and in the Indenture including but not limited to Article 11 thereof (which is hereby incorporated by reference).
