W I T N E S S E T H:

WHEREAS, the Issuer has heretofore executed and delivered to the Trustee an Indenture, dated as of even date herewith (the “Original Indenture” and, as amended and supplemented by this First Supplemental Indenture, the “Indenture”), providing for the issuance from time to time of one or more series of the Company’s Notes;

WHEREAS, Section 9.01(g) of the Indenture provides that the Issuer and the Trustee may from time to time enter into one or more indentures supplemental thereto to establish the form or terms of Notes of a new series;

WHEREAS, the Issuer desires to issue, as the initial series of Notes under the Indenture, $585,000,000 aggregate principal amount of 7.5% Senior Notes due 2014 (the “2014 Notes”), the issuance of which has been authorized by a Management Committee Resolution;

WHEREAS, the Issuer, pursuant to the foregoing authority, proposes in and by this First Supplemental Indenture to supplement and amend the Original Indenture, but only insofar as it will apply to the 2014 Notes; and

WHEREAS, all things necessary have been done to make the 2014 Notes, when issued, authenticated and delivered under the Indenture, the valid obligations of the Issuer, and to make this First Supplemental Indenture a valid and legally binding agreement of the Issuer, in accordance with their and its terms;

NOW, THEREFORE:

In consideration of the premises provided for herein, the Issuer and the Trustee mutually covenant and agree for the equal and proportionate benefit of all holders of the 2014 Notes as follows:

ARTICLE 1

THE 2014 NOTES

SECTION 1.1. Designation of Notes; Establishment of Form.

There shall be a series of Notes designated “7.5% Senior Notes due 2014” of the Issuer, and the form thereof shall be substantially as set forth in Exhibit A hereto, which is incorporated into and shall be deemed a part of this First Supplemental Indenture, and may have such letters, numbers or other marks of identification or designation and such legends or endorsements placed thereon as may, consistently with the Indenture, be determined by the officers of the managing member of the Issuer executing such 2014 Notes, as evidenced by their execution of the 2014 Notes.

The 2014 Notes will initially be issued exclusively in the form of one or more Global Notes, and The Depository Trust Company is hereby designated by the Issuer as the Depositary with respect to the 2014 Notes.

SECTION 1.2. Amount, Etc.

The Trustee shall authenticate and deliver 2014 Notes for original issue in an aggregate principal amount of $500,000,000, all upon delivery to the Trustee of a written order by the Issuer for the authentication and delivery of 2014 Notes.

2014 Notes aggregating $500,000,000 shall be issued in the form of a Rule 144A Global Note, and a “zero balance” Regulation S Temporary Global Note shall also be issued for later use.

The authorized aggregate principal amount of 2014 Notes may be increased at any time hereafter and such series may be reopened for issuances of additional 2014 Notes as provided in the last paragraph of Section 2.01 of the Original Indenture, so long as (i) no Event of Default has occurred and is then continuing with respect to the 2014 Notes and (ii) such additional 2014 Notes are fungible for U.S. federal income tax purposes with the 2014 Notes issued on the date hereof so that such additional 2014 Notes will trade as part of a single series with the 2014 Notes issued on the date hereof.

There shall be no sinking fund for the retirement of the 2014 Notes or other mandatory redemption or repurchase obligation.

The Issuer, at its option, may redeem the 2014 Notes in accordance with the provisions of the form of the 2014 Notes set forth in Exhibit A hereto and Article Three of the Original Indenture.
