This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $[ ].

          The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the TIA for a statement of those terms.

          The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the April 16 or October 16 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments.

Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company.

          Initially, the Trustee will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

4. Optional Redemption.

          (a) Except as described below, the Notes are not redeemable at the Company’s option. The Company is not, however, prohibited from acquiring the Notes by means other than a redemption, whether pursuant to a tender offer, open market purchase or otherwise, so long as the acquisition does not otherwise violate the terms of the Indenture.

          (b) The Notes will be redeemable, at any time and from time to time, in whole or in part, at the Company’s option at a redemption price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to, but not including, the date of redemption, and (ii) the sum of the present values of the Remaining Scheduled Payments of principal and interest on the Notes to be redeemed (exclusive of interest accrued to the applicable redemption date) discounted to that redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 35 basis points. Notwithstanding the foregoing, payments of interest on the Notes will be payable to the Holders of those Notes registered as such at the close of business on the relevant record dates according to the terms and provisions of the Indenture.

          (c) Upon presentation in physical, certificated form of any Note to be redeemed in part only, the Company will execute and the Trustee will authenticate and deliver to the Company on the order of the holder thereof, at the Company’s expense, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Note so presented. The Company may at any time purchase Notes in the open market or otherwise at any price. Any Notes that are redeemed or purchased by the Company shall be delivered to the Trustee for cancellation and may not be reissued or resold.

          Upon a Change of Control Triggering Event, Holders of securities will have the right, subject to certain conditions specified in the Indenture, to cause the Company to repurchase all or any part of the Securities of such Holder at a purchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date that is on or prior to the date of purchase) as provided in, and subject to the terms of, the Indenture.

8. Denominations; Transfer; Exchange.

          The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and in integral multiples of $1,000 in excess thereof.

No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.
