[REVERSE OF SECURITY]

This Security is one of a duly authorized issue of securities of the Company (the “Securities”) issued under the Indenture, dated as of September 14, 2004 (the “Indenture”), between the Company and JPMorgan Chase Bank, as Trustee (in such capacity, the “Trustee,” which term includes any successor trustee under 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, the holders of Senior Obligations and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered.

All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

The Company may, on any Interest Payment Date, at its option, upon not less than thirty (30) days’ nor more than sixty (60) days’ written notice to the Holders of the Securities (unless a shorter notice period shall be satisfactory to the Trustee) on or after December 15, 2009 and subject to the terms and conditions of Article XI of the Indenture, redeem this Security in whole at any time or in part from time to time at a Redemption Price equal to one hundred percent (100%) of the principal amount hereof, together, in the case of any such redemption, with accrued interest, including any Additional Interest, to but excluding the date fixed for redemption; subject to there being no, or the satisfaction of any, Payment Restrictions.

In the event of redemption of this Security in part only, a new Security or Securities for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.  If less than all the Securities are to be redeemed, the particular Securities to be redeemed shall be selected not more than sixty (60) days prior to the Redemption Date by the Trustee from the Outstanding Securities not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a portion of the principal amount of any Security.

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee at any time to enter into a supplemental indenture or indentures for the purpose of modifying in any manner the rights and obligations of the Company and of the Holders of the Securities, with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities. The Indenture also contains provisions permitting Holders of specified percentages in principal amount of the Securities, on behalf of the Holders of all Securities, 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture nor any provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium, if any, and interest, including any Additional Interest (to the

extent legally enforceable), on this Security at the times, place 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 Security is registrable in the Securities Register upon surrender of this Security for registration of transfer at the office or agency of the Company maintained for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Securities Registrar and duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing and, thereupon, one or more new Securities of like tenor of authorized denominations and for the same aggregate principal amount will be issued to the designated transferee or transferees.

The Securities are issuable only in registered form without coupons in minimum denominations of $100,000 and any integral multiples of $1,000 in excess thereof.  As provided in the Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities and of like tenor of a different authorized denomination as requested by the Holder surrendering the same.

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 cover any tax or other governmental charge payable in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

The Company and, by its acceptance of this Security or a beneficial interest herein, the Holder of, and any Person that acquires a beneficial interest in, this Security agree that, for United States federal, state and local tax purposes, it is intended that this Security constitute indebtedness.

This Security shall be construed and enforced in accordance with and governed by the laws of the State of New York, without reference to its conflict of laws provisions (other than Section 5-1401 of the General Obligations Law).
