WHEREAS, Section 5.01 of the Indenture permits that the Merger may occur so long as, among other things, the Issuer and the Guarantors execute and deliver to the Trustee a supplemental indenture pursuant to which each Guarantor shall expressly confirm that its Guarantee shall continue to apply to the Issuer’s Obligations under the Notes and the Indenture; and

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture without the consent of the Holders.

Each Guarantor hereby agrees to continue to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Indenture, including, but not limited to, Article 10 thereof.

(3)Notices.  All notices or other communications to the Issuer or any Guarantor shall be given as provided in Section 12.02 of the Indenture.

(4)Execution and Delivery. Each Guarantor agrees that its Guarantee shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

(5)Ratification of Indenture; Supplemental Indentures 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.

(6)No Recourse Against Others.

Each Holder by accepting Notes waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

(9)Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

(10)The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Issuer and each Guarantor.
