The Original Indenture and any and all indentures and instruments supplemental thereto are hereinafter sometimes collectively called the “Indenture.”

RECITALS OF THE COMPANY

The Original Indenture was authorized, executed and delivered by the Company to provide for the issuance from time to time of its Securities (such term and all other capitalized terms used herein without definition having the meanings assigned to them in the Original Indenture), to be issued in one or more series as contemplated therein, and to provide security for the payment of the principal of and premium, if any, and interest, if any, on such Securities.

The Company has heretofore executed and delivered to the Trustee Supplemental Indentures for the purposes recited therein and for the purpose of creating series of Securities as set forth in Schedule A hereto.

Pursuant to Article Three of the Original Indenture, the Company wishes to establish a nineteenth series of Securities, such series of Securities to be hereinafter sometimes called “Securities of the Nineteenth Series,” and a twentieth series of Securities, such series of Securities to be hereinafter sometimes called the “Securities of the Twentieth Series.”

As contemplated in Section 301 of the Original Indenture, the Company further wishes to establish the designation and certain terms of the Securities of the Nineteenth Series and the Securities of the Twentieth Series. The Company has duly authorized the execution and delivery of this Supplemental Indenture No. 18 to establish the Securities of the Nineteenth Series and the Securities of the Twentieth Series and the designation and certain terms thereof, and has duly authorized the issuance of such Securities; and all acts necessary to make this Supplemental Indenture No. 18 a valid agreement of the Company, and to make the Securities of the Nineteenth Series and the Securities of the Twentieth Series valid obligations of the Company, have been performed.

NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE NO. 18 WITNESSETH, that, for and in consideration of the premises and of the purchase of the Securities of the Nineteenth Series and the Securities of the Twentieth Series by the Holders thereof and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, it is mutually covenanted and agreed, for the equal and proportionate benefit of the Holders of the Securities of the Nineteenth Series and the Securities of the Twentieth Series, as follows:

ARTICLE One

SECTION 102. (a) Covenants with respect to the Securities of the Nineteenth Series. So long as any Securities of the Nineteenth Series shall remain Outstanding, the following shall be an additional covenant of the Company under the Indenture: So long as any Securities of the Nineteenth Series shall remain Outstanding, the Company shall not cause or permit the Release Date to be established, as contemplated in Section 1811 of the Original Indenture.

(b) Covenants with respect to the Securities of the Twentieth Series. So long as any Securities of the Twentieth Series shall remain Outstanding, the following shall be an additional covenant of the Company under the Indenture: So long as any Securities of the Twentieth Series shall remain Outstanding, the Company shall not cause or permit the Release Date to be established, as contemplated in Section 1811 of the Original Indenture.

SECTION 103. Satisfaction and Discharge.

(a)                an instrument wherein the Company, notwithstanding the satisfaction and discharge of its indebtedness in respect of such Securities, shall retain the obligation (which shall be absolute and unconditional) irrevocably to deposit with the Trustee or Paying Agent such additional sums of money, if any, or additional Eligible Obligations (meeting the requirements of Section 801), if any, or any combination thereof, at such time or times, as shall be necessary, together with the money and/or Eligible Obligations theretofore so deposited, to pay when due the principal of and premium, if any, and interest due and to become due on such Securities or portions thereof, all in accordance with and subject to the provisions of said Section 801; provided, however, that such instrument may state that the obligation of the Company to make additional deposits as aforesaid shall be subject to the delivery to the Company by the Trustee of a notice asserting the deficiency accompanied by an opinion of an independent public accountant of nationally recognized standing, selected by the Trustee, showing the calculation thereof (which opinion shall be obtained at the expense of the Company); or

(b)               an Opinion of Counsel to the effect that the Holders of such Securities, or portions of the principal amount thereof, will not recognize income, gain or loss for United States federal income tax purposes as a result of the satisfaction and discharge of the Company’s indebtedness in respect thereof and will be subject to United States federal income tax on the same amounts, at the same times and in the same manner as if such satisfaction and discharge had not been effected.
