     WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of May 12, 2003, providing for the issuance of an aggregate principal amount of 2.50% Exchangeable Senior Subordinated Debentures due 2033 (the “Notes”);

     WHEREAS, the Indenture provides that under certain circumstances each Guaranteeing Subsidiary shall 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 (the “Subsidiary Guarantee”); and

     WHEREAS, pursuant to Section 11.06 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, each Guaranteeing 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 Guarantee. Each Guaranteeing Subsidiary hereby agrees to jointly and severally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, the Notes or the obligations of the Company hereunder or thereunder, on a senior subordinated basis pursuant to, and in accordance with, the terms and conditions of Article Six of the Indenture and to otherwise assume the obligations and rights as a Guarantor under the Indenture.

     3.      Releases. Upon receipt by the Trustee of a request by the Company accompanied by an Officers’ Certificate certifying as to compliance with Section 6.03 of the Indenture, the Trustee shall deliver an appropriate instrument evidencing such release.

Each Holder of the 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.
