        That the parties hereto hereby agree as follows:

        Section 1    Defined Terms; Rules of Interpretation.    Capitalized terms used herein and not otherwise defined herein shall have the respective meanings ascribed thereto in the Original Indenture. The rules of interpretation set forth in the Original Indenture shall be applied hereto as if set forth in full herein.

        Section 2    Amendment to the Original Indenture.    Section 5.01 of the Original Indenture is hereby amended by deleting the text of such Section in its entirety and replacing it with the following text:

        Section 5.01    When the Company or Guarantors May Merge or Transfer Assets.    (a) The Company shall not consolidate or amalgamate with or merge with or into, or sell, convey, transfer or lease, in one transaction or a series of transactions, directly or indirectly, all or substantially all of its assets to, any Person, unless:

        (1)   (A) the resulting, surviving or transferee Person (the "Successor Company") shall be a Person organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, (B) the Successor Company (if not the Company) shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Company under the Securities and this Indenture and (C) immediately after giving pro forma effect to such transaction, no Default shall have occurred and be continuing; and

        (2)   the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger, sale or transfer and such supplemental indenture, if any, comply with this Indenture.

        For purposes of this Section 5.01, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries would constitute all or substantially all of the properties and assets of the Company on a consolidated

basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

        Upon any transaction in accordance with this Section 5.01(a), the Successor Company shall be the successor to the Company and shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, and the predecessor Company, except in the case of a lease, shall be released from the obligation to pay the principal of and interest on the Securities.

        (b)   Unless otherwise permitted pursuant to Section 10.06, no Guarantor shall, and the Company shall not permit any Guarantor to, consolidate or amalgamate with or merge with or into, or sell, convey, transfer or lease, in one transaction or series of transactions, all or substantially all of its assets to any Person unless: (1) the resulting, surviving or transferee Person (if not such Guarantor) shall be a Person organized and existing under the laws of the United States of America, any state thereof or the District of Columbia and such Person shall expressly assume all the obligations of such Guarantor, if any, under its Guaranty and this Indenture; (2) immediately after giving effect to such transaction or transactions on a pro forma basis (and treating any indebtedness which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as having been issued by such Person at the time of such transaction), no Default shall have occurred and be continuing; and (3) the Company delivers to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger or transfer and such Guaranty Agreement, if any, complies with this Indenture.

This Second Supplemental Indenture shall form a part of the Original Indenture (as modified by the First Supplemental Indenture) for all purposes, and every Holder of any Securities heretofore or hereafter authenticated and delivered pursuant thereto shall be bound hereby. Except only insofar as the Original Indenture (as modified by the First Supplemental Indenture) may be inconsistent with the express provisions of this Second Supplemental Indenture, in which case the terms of this Second Supplemental Indenture shall govern and supersede those contained in the Original Indenture (as modified by the First Supplemental Indenture), this Second Supplemental Indenture shall henceforth have effect so far as practicable as if all the provisions of the Original Indenture, the First Supplemental Indenture, and this Second Supplemental Indenture were contained in one instrument.

        Section 4    Counterparts.    This Second Supplemental Indenture may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

        Section 5    Governing Law.    This Second Supplemental Indenture shall be governed by, and construed in accordance with, the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the laws of another jurisdiction would be required thereby.

        Section 6    Concerning the Trustee.    In carrying out the Trustee's responsibilities hereunder, the Trustee shall have all of the rights, protections, and immunities which the Trustee possesses under the Original Indenture (as modified by the First Supplemental Indenture). The recitals contained herein shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Second Supplemental Indenture.
