WHEREAS Sections 4.11 and 10.06 of the Indenture provide that under certain circumstances the Issuer is required to cause the New Guarantor to execute and deliver to the Trustee a supplemental indenture pursuant to which the New Guarantor shall unconditionally guarantee all the Issuer’s Obligations under the Securities and the Indenture pursuant to a Guarantee on the terms and conditions set forth herein; and

WHEREAS pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture;

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the New Guarantor and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows:

1.Defined Terms.  As used in this Supplemental Indenture, terms defined in the Indenture or in the preamble or recitals hereto are used herein as therein defined, except that the term “Holders” in this Guarantee shall refer to the term “Holders” as defined in the Indenture and the Trustee acting on behalf of and for the benefit of such Holders.  The words “herein,” “hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof.

2.Agreement to Guarantee.  The New Guarantor hereby agrees, jointly and severally with all existing Guarantors (if any), to irrevocably and unconditionally guarantee the Issuer’s Obligations under the Securities and the Indenture on the terms and subject to the conditions set forth in the Indenture, including, but not limited to, Article 10 of the Indenture, and to be bound by all other applicable provisions of the Indenture and the Securities and to perform all of the obligations and agreements of a Guarantor under the Indenture.

3.Releases.  A Guarantee as to any Guarantor shall terminate and be of no further force or effect and such Guarantor shall be deemed to be released from all obligations as provided in Section 10.02(b) and (c) of the Indenture.

4.Notices.  All notices or other communications to the New Guarantor shall be given as provided in Section 11.02 of the Indenture.

5.Ratification of Indenture; Supplemental Indentures Part of Indenture.  Except as expressly amended and supplemented hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect.  This Supplemental Indenture shall form a part of the Indenture for all purposes, and every Holder of Securities heretofore or hereafter authenticated and delivered shall be bound hereby.

6.No Recourse Against Others.  No past, present or future director, officer, employee, manager, incorporator, agent or holder of any Equity Interests in the Issuer or of the New Guarantor or any direct or indirect parent corporation, as such, shall have any liability for any obligations of the Issuer or the Guarantors under the Securities, the Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation.  Each Holder of Securities by accepting a Security waives and releases all such liability.  The waiver and release are part of the consideration for issuance of the Securities.  The waiver may not be effective to waive liabilities under the federal securities laws.

7.Governing Law.  THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.  EACH OF THE NEW GUARANTOR AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS SUPPLEMENTAL INDENTURE, THE INDENTURE, THE SECURITIES OR THE TRANSACTION CONTEMPLATED HEREBY.

10.Effect of Headings.  The Section headings herein are for convenience only and shall not affect the construction thereof.

11.The Trustee.  The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the New Guarantor.
