(1) Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Base Indenture.

(2) Assumption of the Obligations. The New Issuer hereby agrees, as of the date hereof, to assume, to be bound by and to be liable, as a primary obligor and not as a guarantor or surety, with respect to, any and all Obligations under the Indentures and the Notes on the terms and subject to the conditions set forth in the Indentures and all other obligations of the Original Issuer under the Indentures and the Notes as if it were the Original Issuer thereunder (so that from and after the date hereof, the provisions of the Indentures and the Notes referring to the Original Issuer (referred to as the “Company” in the Indentures) shall instead refer to the New Issuer).

(3) No Recourse Against Others. No past, present or future director, officer, employee, incorporator, member, partner or equity holder of the New Issuer or the Original Issuer or any parent company (other than an obligor under the Notes) will have any liability for any obligations of the New Issuer or the Original Issuer under the Notes, the Indentures or this Supplemental Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. 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.

(4) Ratification of Base Indenture. The Base Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. Upon the execution and delivery of this Supplemental Indenture by the New Issuer and the Trustee, this Supplemental Indenture shall form a part of the Base Indenture for all purposes, and the New Issuer, the Trustee and every Holder of each series of Notes heretofore or hereafter authenticated and delivered shall be bound hereby.
