RECITALS

WHEREAS, the Issuer and the Subsidiary Guarantors have heretofore executed and delivered to the Trustee an Indenture (the “Indenture”) dated as of March 29, 2011, providing for the initial issuance of $275 million aggregate principal amount of 7.875% Senior Notes due 2019 (the “Securities”);

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee, the Issuer and the Subsidiary Guarantors are authorized to modify or amend the Indenture without notice to or consent of any Securityholder to cure any defect or make any change that, in the good faith opinion of the Board of Directors of Issuer, does not materially and adversely affect the rights of any Holder;

WHEREAS, Section 4.03(a)(6) of the Indenture currently states that a Restricted Subsidiary may make a Guarantee of Indebtedness in accordance with Section 4.06 of the Indenture, but such reference to Section 4.06 is clearly erroneous and a defect because Section 4.06 does not address subsidiary guarantees;

WHEREAS, Section 4.10 of the Indenture, titled “Limitation on Issuance of Guarantees by Restricted Subsidiaries”, does address Guarantees of Indebtedness made by Restricted Subsidiaries and includes the conditions under which such Guarantees can be made;

WHEREAS, the Offering Memorandum dated March 24, 2011 for the Securities issued pursuant to the Indenture states in the description of Section 4.03 on page 91, that a Restricted Subsidiary may make a Guarantee of Indebtedness in accordance with the “Limitation on Issuance of Guarantees by Restricted Subsidiaries” covenant, which is a reference to Section 4.10 of the Indenture;

WHEREAS, the Board of Directors of the Issuer has concluded in good faith that making a change to cure such defect does not materially and adversely affect the rights of any Holder;

WHEREAS the Trustee, the Issuer and the Subsidiary Guarantors wish to and are authorized to execute and deliver this Supplemental Indenture to amend the Indenture to cure such defect by changing the section reference in Section 4.03(a)(6) of the Indenture from Section 4.06 to Section 4.10, thereby conforming the text of the Indenture to the clear intention of the parties as well as the description of such section contained in the Offering Memorandum and allowing for a rational reading of Section 4.03;

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the Issuer, the Subsidiary Guarantors and the Trustee mutually covenant and agree as follows:

1. Capitalized Terms. Capitalized terms used in this Supplemental Indenture (including the recitals hereto) without definition shall have the meanings set forth in the Indenture.

2. Amendment to Indenture. Section 4.03(a)(6) is hereby amended by replacing the reference to Section 4.06 in such section with a reference to Section 4.10. For clarity, Section 4.03(a)(6) shall read as follows:

“Guarantees of the Securities and Guarantees of Indebtedness of the Company or any Restricted Subsidiary of the Company by any other Restricted Subsidiary of the Company; provided the Guarantee of such Indebtedness is permitted by and made in accordance with Section 4.10;”

3. Ratification of Indenture; Supplemental Indenture Part of Indenture. Except as expressly amended hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and every Holder of Securities heretofore or hereafter authenticated and delivered shall be bound hereby.

4. Trustee’s Disclaimer. The Trustee makes no representation or warranty as to the validity or sufficiency of this Supplemental Indenture.

5. Governing Law. THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT 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.

6. Counterparts. This Supplemental Indenture may be executed in two or more counterparts, all of which shall be considered one and the same agreement.

7. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction thereof.

8. Conflict with the Trust Indenture Act. If any provision of this Supplemental Indenture limits, qualifies or conflicts with any provision of the Trust Indenture Act of 1939 (the “TIA”) that is required under the TIA to be part of and govern any provision of this Supplemental Indenture, the provision of the TIA shall control. If any provision of this Supplemental Indenture modifies or excludes any provision of the TIA that may be so modified or excluded, the provision of the TIA shall be deemed to apply to the Indenture as so modified or to be excluded by this Supplemental Indenture.

IN WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to be duly executed as of the date first written above.
