[FORM OF REVERSE]

This Debenture is one of a duly authorized issue of securities of the Company designated as its “7.375% Senior Debentures due 2032” (herein called the “Debentures”), initially limited in aggregate principal amount to U.S. $250,000,000, issued and to be issued under an Indenture, dated as of March 9, 2001 (herein called the “Base Indenture”), between the Company and JPMorgan Chase Bank (formerly known as The Chase Manhattan Bank), as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Base Indenture), and a Second Supplemental Indenture, dated as of June 18, 2002, between the Company and the Trustee (the “Second Supplemental Indenture”; the Base Indenture, as supplemented by the Second Supplemental Indenture, the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Debentures and of the terms upon which the Debentures are, and are to be, authenticated and delivered. As provided in the Indenture and subject to certain limitations therein set forth, Debentures are exchangeable for a like aggregate principal amount of Debentures of any authorized denominations as requested by the Holder surrendering the same upon surrender of the Debenture or Debentures to be exchanged, at the Corporate Trust Office of the Trustee. The Trustee upon such surrender by the Holder will issue the new Debentures in the requested denominations.

No sinking fund is provided for the Debentures.

Each of the Debentures may be redeemed at the option of the Company (an “Optional Redemption”) at any time, in whole or in part, upon notice as set forth in Section 1104 of the Indenture, at a Redemption Price calculated in accordance with Section 4.1 of the Second Supplemental Indenture; provided, however, that interest installments on Debentures whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Debentures, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture.

In the event of a redemption of the Debentures, the Company will not be required (a) to register the transfer or exchange of Debentures for a period of 15 days immediately preceding the selection of Debentures for redemption or (b) to register the transfer or exchange of any Debenture, or portion thereof, called for redemption.

In any case where the due date for the payment of the principal of, premium, if any, or interest on any Debenture at any Place of Payment as the case may be, is not a Business Day, then payment of principal, premium, if any, or interest of such Debenture need not be made on or by such date at such place but may be made on or by the next succeeding Business Day, with the same force and effect as if made on the date for such payment or the date fixed for redemption, and, provided that so long as such payment is made on or by the next succeeding Business Day, no interest shall accrue on the amount so payable for the period after such date.

[The following paragraph shall appear in each Global Security:

In the event of a deposit or withdrawal of an interest in this Debenture, including an exchange, redemption or transfer of this Debenture in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of The Depository Trust Company applicable to, and as in effect at the time of, such transaction.]

[The following paragraph shall appear in each Debenture that is not a Global Security:

In the event of redemption of this Debenture in part only, a new Debenture or Debentures for the unredeemed portion hereof will be issued in the name of the Holder hereof.]

If an Event of Default shall occur and be continuing, the principal of all the Debentures, together with accrued interest to the date of declaration, may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the written consent of the Holders of not less than a majority in principal

amount of the Securities at the time Outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Debentures at the time Outstanding, on behalf of the Holders of all the Debentures, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Debenture shall be conclusive and binding upon such Holder and upon all future Holders of this Debenture and of any Debenture issued in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Debenture or such other Debenture.

As provided in and subject to the provisions of the Indenture, the Holder of this Debenture shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default, the Holders of not less than 25% in principal amount of the Debentures that are Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it and the Trustee shall not have received from the Holders of a majority in principal amount of the Debentures that are Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by any Holder of this Debenture for the enforcement of any payment of principal hereof, or any premium of interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Debenture or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Debenture at the times, places and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Debenture is registrable on the Security Register upon surrender of this Debenture for registration of transfer at the Corporate Trust Office of the Trustee or at such other office or agency of the Company as may be designated by it for such purpose in the Borough of Manhattan, The City of New York or the City of Chattanooga, Tennessee (which shall initially be an office or agency of the Trustee), or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Security Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Debentures, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees by the Security Registrar. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to recover any tax or other governmental charge payable in connection therewith.

Prior to due presentation of this Debenture for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Debenture is registered, as the owner thereof for all purposes, whether or not such Debenture be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

No recourse for the payment of the principal (and premium, if any) or interest on this Debenture and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Debenture, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of consideration for the issue hereof, expressly waived and released.
