     WHEREAS, Section 4.12 of the Indenture provides that under certain circumstances the Company is required to cause the New Guarantor to execute and deliver to the Trustee for the benefit of the Holders a supplemental agreement pursuant to which the New Guarantor shall unconditionally guarantee all of the Company’s obligations under the Securities pursuant to a Guarantee on the terms and conditions set forth herein;

     NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the New Guarantor covenants and agrees for the equal and ratable benefit of the Holders of the Securities as follows:
