5.50% Note Due 2013

This Note is one of a duly authorized issue of debentures, notes, bonds or other evidences of indebtedness of the Issuer (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an indenture dated as of April 1, 1991 (herein called the “Indenture”), duly executed and delivered by the Issuer to The Bank of New York, Trustee (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer and the holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Note is one of a series of Securities designated as the 5.50% Notes Due 2013 of the Issuer, initially limited in aggregate principal amount to $200,000,000 (the “Notes”). The Issuer may, without notice to or the consent of the Holders of the outstanding Notes, issue additional Securities of the same tenor as the Notes so that such additional Securities and the outstanding Notes shall form a single series of Securities under the Indenture.

In case an Event of Default with respect to the 5.50% Notes Due 2013, as defined in the Indenture, shall have occurred and be continuing, the principal hereof may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the holders of not less than 66 ²/3% in aggregate principal amount of the Securities at the time Outstanding (as defined in the Indenture) of all series to be affected (voting as one class), evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Securities of each such series; provided, that no such supplemental indenture shall (i) extend the final maturity of any Security, or reduce the principal amount thereof or any premium thereon, or reduce the rate or extend the time of payment of any interest thereon, or impair or affect the rights of any holder to institute suit for the payment thereof, without the consent of the holder of each Security so affected, or (ii) reduce the aforesaid percentage of Securities, the holders of which are required to consent to any such supplemental indenture, without the consent of the holder of each Security affected. It is also provided in the Indenture that, with respect to certain defaults or Events of Default regarding

R-1

the Securities of any series, prior to any declaration accelerating the maturity of such Securities, the holders of a majority in aggregate principal amount Outstanding of the Securities of such series (or, in the case of certain defaults or Events of Default, all or certain series of the Securities) may on behalf of the holders of all the Securities of such series (or all or certain series of the Securities, as the case may be) waive any such past default or Event of Default and its consequences. The preceding sentence shall not, however, apply to a default in the payment of the principal of or premium, if any, or interest on any of the Securities. Any such consent or waiver by the holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

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

The Notes are redeemable, in whole or in part, at the option of the Issuer at any time at a redemption price equal to the greater of:

plus, in each case, accrued interest on the Notes to the date of redemption. The provisions of Article Eleven of the Indenture shall apply to any redemption of the Notes.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer

R-2

Quotations, or (2) if the Trustee obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

“Quotation Agent” means the Reference Treasury Dealer appointed by the Issuer.

“Reference Treasury Dealer” means each of J.P. Morgan Securities Inc. and UBS Securities LLC, and their respective successors, and three other nationally recognized investment banking firms that are primary U.S. government securities dealers in the United States (a “Primary Treasury Dealer”) specified from time to time by the Issuer; provided, that if any Reference Treasury Dealer shall cease to be a Primary Treasury Dealer, the Issuer shall substitute another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Issuer, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of the notes to be redeemed. Unless the Issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the notes or portions thereof called for redemption.

The Notes will not be entitled to the benefit of any sinking fund.

The Notes are issuable in registered form without coupons at the office or agency of the Issuer in the Borough of Manhattan, The City of New York, and in the manner and subject to the limitations provided in the Indenture, but without the payment of any service charge, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations.

Upon due presentment for registration of transfer of this Note at the office or agency of the Issuer in the Borough of Manhattan, The City of New York, a new Note or Notes of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange therefor, subject to the

R-3

limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Issuer, the Trustee and any authorized agent of the Issuer or the Trustee may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and premium, if any, and subject to the provisions on the face hereof, interest hereon, and for all other purposes, and neither the Issuer nor the Trustee nor any authorized agent of the Issuer or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement of the Issuer in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, of the Issuer or of any successor corporation, either directly or through the Issuer or any successor corporation, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein which are defined in the Indenture shall have the respective meanings assigned thereto in the Indenture.
