The parties hereto agree as follows:

1.Definitions. All capitalized terms used and not otherwise defined herein have the respective meanings ascribed to such terms in the Indenture.

2.Effect. This Supplemental Indenture shall become effective on October 12, 2011.

3.Definitions. The definition of "Outstanding" in Section 1.01 of the Indenture is hereby amended to read in its entirety as follows:

""Outstanding", when used with respect to Securities, means, as of any particular time, all such Securities theretofore authenticated and delivered under this Indenture, except:

(i)Securities theretofore cancelled by the Trustee or delivered to the Trustee for cancellation;

(ii)Securities, or portions thereof, for whose payment or redemption money in the necessary amount has been theretofore deposited with the Trustee or any Paying Agent (other than the Corporation) in trust or set aside and segregated in trust by the Corporation (if the Corporation shall act as its own Paying Agent) for the Holders of such Securities; provided that, if such Securities are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has been made;

(iii)Securities which have been paid pursuant to Section 3.06 or have been mutilated, lost, stolen or destroyed and in exchange for or in lieu of which other Securities have been authenticated and delivered pursuant to this Indenture; and

(iv)Securities which have been defeased pursuant to Article Twelve; provided, however, that in determining whether the Holders of the requisite

principal amount of the Securities of any or all series then Outstanding have voted or

have signed or given any request, demand, authorization, direction, notice, consent, requisition, waiver or other instrument or have taken any action or constitute a quorum at any meeting of Holders hereunder, (a) the principal amount of an Original Issue Discount Security which shall be deemed to be Outstanding for such purposes shall be the portion of the principal amount thereof that could be declared to be due and payable upon the occurrence of an Event of Default and the continuation thereof pursuant to the terms of such Original Issue Discount Security as of such time and (b) Securities owned by the Corporation, or any other obligor upon the Securities shall be disregarded and deemed

not to be Outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent, requisition, waiver or other instrument or action or on the Holders present or represented at any meeting of Holders, only Securities which the Responsible Officer of the Trustee knows to be so owned shall be so disregarded;"

4.Responsibility of Trustee. The Trustee shall not be responsible for the sufficiency of this Supplemental Indenture or as to the due execution thereof by the Corporation or as to recitals of fact contained herein, all of which are made solely by the Corporation.

5.Governing Law. This Supplemental Indenture shall be governed by and construed in accordance with the laws of the State of New York.

6.Counterparts. This Supplemental Indenture may be executed in one or more counterparts, each of which shall be an original, but all of which together shall constitute one and the same document.

7.Effect on Indenture. This Supplemental Indenture shall form a part of the Indenture for all purposes and every Holder of Notes heretofore or hereafter authenticated and delivered shall be bound hereby. Except as expressly set forth herein, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. In the event of a conflict between the terms and conditions of this Supplemental Indenture and the terms and conditions of the Indenture, then the terms and conditions of this Supplemental Indenture shall prevail. For the avoidance of doubt, the intention of the Corporation is that the debt obligations of the Corporation, which were incurred pursuant to the Indenture and which are evidenced by the Notes, will continue in full force and effect and will not be settled, extinguished, cancelled, replaced, rescinded or novated by the amendments pursuant to this

Supplemental Indenture.
