NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Company, the New Guarantor, and the Trustee and Notes Collateral Agent mutually agree for the benefit of the Holders of the Securities as follows:
1. Agreement to Guarantee. The New Guarantor hereby agrees to unconditionally guarantee all of the Company’s obligations under the Securities and the Indenture and that its obligations to the Holders and the Trustee pursuant to this Supplemental Indenture shall be as expressly set forth with respect to all Guarantors in Article XII of the Indenture and in such other provisions of the Indenture as are applicable to all Guarantors, and reference is made to the Indenture for the precise terms of this Supplemental Indenture. The terms of Article XII of the Indenture and such other provisions of the Indenture as are applicable to all Guarantors are incorporated herein by reference.
2. Execution and Delivery of Guarantee.
(a) To evidence its Guarantee set forth in this Supplemental Indenture, the New Guarantor is, contemporaneously with its execution and delivery of this Supplemental Indenture, executing and delivering to the Trustee a Guarantee substantially in the form of Exhibit E to the Indenture. The validity and enforceability of the Guarantee set forth in this Supplemental Indenture and such Guarantee shall not be affected by the fact that it is not affixed to any particular Security.
(b) The New Guarantors hereby agrees that its Guarantee set forth in this Supplemental Indenture and such Guarantee shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Guarantee.
(c) If an Officer of the New Guarantor whose signature is on this Supplemental Indenture or such Guarantee no longer holds that office at the time the Trustee authenticates any Security on which such Guarantee is endorsed or at any time thereafter, such Guarantor’s Guarantee of such Security shall nevertheless be valid.
(d) The delivery of any Security by the Trustee, after the authentication thereof under the Indenture, shall constitute due delivery of the Guarantee set forth in this Supplemental Indenture and such Guarantee on behalf of the New Guarantor.

Each Securityholder by accepting a Security waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Securities.
