     WHEREAS, Section 301 of the Indenture provides that all Securities of any one series need not be issued at the same time and that a series of Securities may be reopened, without the consent of the Holders, for increases in the aggregate principal amount of such series of Securities and issuances of additional Securities of such series; and

     WHEREAS, in connection with the consummation of the exchange offers contemplated by the Company’s Registration Statement on Form S-4 (Registration No. 333-   ) (including the prospectus dated      , 2006 and forming a part thereof), in exchange for the surrender of the Company’s outstanding 7.75% Senior Notes due 2032 and the Company’s outstanding 7.75% Senior Debentures due October 15, 2035, the Company desires to issue up to $150,000,000 in additional aggregate principal amount of notes (the “Additional Medium Term Notes” and collectively with the Original Medium Term Notes, the “Medium Term Notes”) having substantially the same terms as, having the same CUSIP number as, to be issued using substantially the same form of note certificate as, and constituting a part of the same series as, the Original Medium Term Notes; and

     WHEREAS, pursuant to Section 901 of the Indenture, without the consent of any Holders, the Company and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental to the Indenture to establish the form or terms of securities of any series as permitted by Sections 201 and 301 of the Indenture; and

     WHEREAS, all action on the part of the Company necessary to authorize the issuance of the Additional Medium Term Notes under the Original Indenture, the January 2001 Board Resolutions, the January 2002 Officer’s Certificate and this Supplemental Indenture has been duly taken; and

     WHEREAS, all acts and things necessary to make the Additional Medium Term Notes, when executed by the Company and authenticated and delivered by the Trustee as provided in the Indenture, the valid and binding obligations of the Company and to make this Supplemental Indenture a valid and binding agreement in accordance with the Original Indenture have been done or performed;

     NOW, THEREFORE, in consideration of the premises, agreements and obligations set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree, for the equal and proportionate benefit of all Holders of the Medium Term Notes, as follows:
