Each capitalized term used but not defined herein shall have the meaning assigned to such term in the Base Indenture (as defined below).

WHEREAS, the Company, the Subsidiary Guarantors and The Bank of New York Mellon Trust Company, N.A., a national banking association, as trustee (the “Existing Trustee”) are parties to an Indenture, dated as of August 2, 2010 (the “Base Indenture,” as supplemented, the “Indenture”), providing for the issuance by the Company from time to time of its debentures, notes, bonds and other evidences of indebtedness, issued and to be issued in one or more series unlimited as to principal amount (the “Securities”), and the guarantee by each Subsidiary Guarantor of each such series of such Securities, the terms of which provide for such guarantee; and

WHEREAS, Section 7.08 of the Base Indenture permits the Company to appoint a separate Trustee for any one or more series of Securities; and

WHEREAS, pursuant to Section 9.01(5) of the Indenture, the Company and the Subsidiary Guarantors may amend or supplement the Indenture or the Securities of any series without notice to or consent of any Holder to evidence the acceptance or appointment by a separate Trustee with respect to one or more series of Securities; and

WHEREAS, the Company desires hereby to appoint the Series Trustee as Trustee under the Indenture so that the Series Trustee may henceforth serve as the Trustee with respect to, and only with respect to, one or more series of Securities issued on or after the date hereof; and

WHEREAS, the Existing Trustee shall remain the Trustee with respect to each series of Securities issued prior to the date hereof; and

WHEREAS, all things necessary have been done to make this Supplemental Indenture a legal, valid and binding agreement of the parties hereto, enforceable in accordance with its terms.

NOW, THEREFORE, in consideration of the agreements and obligations ser forth herein and for other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto hereby agree that the following provisions shall supplement the Base Indenture:

The Company hereby appoints the Series Trustee as Trustee under the Indenture with respect to, and only with respect to, each series of Securities so designated, and by execution

hereof the Series Trustee accepts such appointment. Pursuant to the Indenture, all the rights, powers, trusts and duties of the Trustee under the Base Indenture shall be vested in the Series Trustee with respect to each series of Securities for which the Series Trustee shall have been designated as the Trustee. Nothing in this Supplemental Indenture shall be construed to amend in any respect the rights, powers, trusts and duties of the Existing Trustee under the Indenture with respect to all of the series of Securities as to which it has served and continues to serve as Trustee. The Existing Trustee shall have no rights, powers, trusts and duties with respect to any series of Securities for which the Series Trustee is the Trustee.

The Series Trustee hereby represents that it is qualified and eligible under the provisions of the Trust Indenture Act and the Base Indenture, including Section 7.10 thereof, to accept its appointment as Trustee with respect to each series of Securities for which it may be designated as Trustee under the Indenture and hereby accepts the appointment as such Trustee.

Unless otherwise expressly provided in connection with the establishment of a series of Securities, the Series Trustee shall serve as “Registrar,” “Paying Agent” and “Conversion Agent” with respect to each series of Securities for which it shall be designated as the Trustee.

The Series Trustee assumes no additional duties, responsibilities or liabilities by reason of this Supplemental Indenture other than as set forth in the Base Indenture and, in carrying out its responsibilities hereunder and thereunder, the Series Trustee shall have all of the rights, powers, privileges, protections, duties, immunities and obligations which it possesses under the Base Indenture. The Series Trustee shall not constitute a successor Trustee with respect to the Existing Trustee, and the Existing Trustee and the Series Trustee shall not constitute co-trustees. Nothing in this Supplemental Indenture shall be construed to create or impose any liability on the Existing Trustee for any acts or omissions of the Series Trustee. The Series Trustee shall have no liability for any acts or omissions of the Existing Trustee. The Existing Trustee shall continue to constitute a Trustee under the Base Indenture and may be appointed as the Trustee with respect to a series of Securities after the date hereof.

References in this Supplemental Indenture and in any supplemental indenture pursuant to which the terms of any Securities with respect to which the Series Trustee shall be the Trustee to sections of the Base Indenture that require or permit actions by the Trustee with respect to any such Securities shall be deemed to require or permit actions only by the Series Trustee and the Existing Trustee shall have no responsibility therefor.

In any series of Securities for which the Series Trustee serves as Trustee, express references in the Base Indenture to The Bank of New York Mellon Trust Company, N.A. shall be deemed to be references to the Series Trustee.

Any notice or communication to the Company, any Subsidiary Guarantor or the Series Trustee or any Agent shall be sufficiently given if given in accordance with the Base Indenture, addressed as follows:

The Company or any Subsidiary Guarantor or the Series Trustee or any Agent by notice to the other may designate additional or different addresses for subsequent notices or communications.

The recitals in this Supplemental Indenture are made by the Company only and not by the Existing Trustee or the Series Trustee.

As amended and supplemented hereby, the Indenture is in all respects ratified and confirmed, and the Indenture and this Supplemental Indenture shall be read, taken and construed as one and the same instrument with respect to, and only with respect to, the series of Securities for which for which the Series Trustee shall be the Trustee.

The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same instrument.

THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS TO THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

In case any provision of this Supplemental Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

IN WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to be duly executed as of the day and year first above written.
