(d) The Indenture is hereby amended by amending Section 5.01 to read in its entirety as follows:

The Issuer shall not, directly or indirectly, in a single transaction or a series of related transactions, (a) consolidate or merge with or into (other than a merger that satisfies the requirements of clause (1) below with a Wholly-Owned Restricted Subsidiary solely for the purpose of changing the Issuer’s jurisdiction of incorporation to another State of the United States), or sell, lease, transfer, convey or otherwise dispose of or assign all or substantially all of the assets of the Issuer or the Issuer and the Restricted Subsidiaries (taken as a whole) or (b) adopt a Plan of Liquidation unless, in either case:

(1) either:

(a) the Issuer will be the surviving or continuing Person; or

(b) the Person formed by or surviving such consolidation or merger or to which such sale, lease, conveyance or other disposition shall be made (or, in the case of a Plan of Liquidation, any Person to which assets are transferred) (collectively, the “Successor”) is a corporation or limited liability company organized and existing under the laws of any State of the United States of America or the District of Columbia, and the Successor expressly assumes, by supplemental indenture in form and substance satisfactory to the Trustee, all of the obligations of the Issuer under the Notes, this Indenture and the Registration Rights Agreement; provided that at any time the Successor is a limited liability company, there shall be a co-issuer of the Notes that is a corporation; and

(2) immediately prior to and immediately after giving effect to such transaction and the assumption of the obligations as set forth in clause (1)(b) above and the incurrence of any Indebtedness to be incurred in connection therewith, no Default shall have occurred and be continuing.

Except as provided under Section 10.04 no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, whether or not affiliated with such Guarantor, unless:

Upon any consolidation, combination or merger of the Issuer or a Guarantor, or any transfer of all or substantially all of the assets of the Issuer in accordance with the foregoing, in which the Issuer or such Guarantor is not the continuing obligor under the Notes or its Note Guarantee, the surviving entity formed by such consolidation or into which the Issuer or such Guarantor is merged or to which the conveyance, lease or transfer is made will succeed to, and be substituted for, and may exercise every right and power of, the Issuer or such Guarantor under this Indenture, the Notes and the Note Guarantees with the same effect as if such surviving entity had been named therein as the Issuer or such Guarantor and, except in the case of a conveyance, transfer or lease, the Issuer or such Guarantor, as the case may be, will be released from the obligation to pay the principal of and interest on the Notes or in respect of its Note Guarantee, as the case may be, and all of the Issuer’s or such Guarantor’s other obligations and covenants under the Notes, this Indenture and its Note Guarantee, if applicable.

Notwithstanding the foregoing, any Restricted Subsidiary may merge into the Issuer or another Restricted Subsidiary.

Subject to Sections 7.01 and 7.02, the Trustee shall not be charged with knowledge of any Default, Event of Default, Change of Control or Asset Sale or the requirement for payment of Liquidated Damages unless written notice thereof shall have been given to a Responsible Officer at the Corporate Trust Office of the Trustee by the Issuer or any other Person.

2. Effectiveness. This Eighth Supplemental Indenture supplements the Indenture and shall be a part and subject to all of the terms thereof. Except as supplemented hereby, the Indenture shall continue in full force and effect.

The amendments effected by this Eighth Supplemental Indenture shall take effect on the date that each of the following conditions shall have been satisfied or waived:

(a) each of the parties hereto shall have executed and delivered this Eighth Supplemental Indenture; and

(b) the Issuer shall have received written consent to these amendments from the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, except with respect to the amendments to Section 4.20 of the Indenture regarding changes of control which requires the consent of the Holders of at least two-thirds of the aggregate principal amount of Notes then outstanding;
