assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the Issuer or Co-Issuer, as applicable, shall refer instead to the successor Issuer or Co-Issuer, as applicable), and may exercise every right and power of the Issuer or Co-Issuer, as applicable under this Indenture with the same effect as if such successor Person had been named as the Issuer or Co-Issuer, as applicable, herein, and the predecessor Issuer or Co-Issuer, as applicable, will be automatically released and discharged from its obligations under the Indenture and the Notes; provided that the predecessor Issuer or Co-Issuer, as applicable, shall not be relieved from its obligation in the case of a lease.”

Section 5.  This Supplemental Indenture is an amendment supplemental to the Indenture and the Indenture and this Supplemental Indenture will henceforth be read together.

Section 6. Except as expressly supplemented and amended by this Supplemental Indenture, the Indenture shall continue in full force and effect in accordance with the provisions thereof, and the Indenture (as supplemented and amended by this Supplemental Indenture) is in all respects hereby ratified and confirmed. This Supplemental Indenture and all its provisions shall be deemed a part of the Indenture in the manner and to the extent herein and therein provided.
