[Reverse of Security]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an indenture (the “Base Indenture”), dated as of February 8, 2001, between the Company and ▇.▇. ▇▇▇▇▇▇ Trust Company, National Association (formerly known as Bank One Trust Company, N.A.), as Trustee (herein called the “Original Trustee”), which term includes any successor trustee, as supplemented by the First Supplemental Indenture, dated as of October 13, 2005, among the Company, the Original Trustee and The Bank of New York, a New York banking corporation, as Series Trustee (herein called the “Series Trustee”, which term includes any successor trustee, and, together with the Original Trustee, the “Trustees”; the Base Indenture as so supplemented, herein called the “Indenture”, which term shall have the meaning assigned to it in the Base Indenture). Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustees and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof initially limited in aggregate principal amount to $300,000,000.

The Securities of this series are subject to redemption upon not less than 30 days’ and not more than 60 days’ notice by mail, at any time, as a whole or in part, at the election of the Company, at a redemption price equal to the greater of (i) 100% of the principal amount of such Securities then outstanding to be redeemed, or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (not including any portion of such payments of interest accrued to the date of redemption) discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 12.5 basis points, plus, in each case, accrued and unpaid interest on the principal amount being redeemed to the redemption date, but interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities, 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.

“Treasury Rate” means, with respect to any redemption date: (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the comparable treasury issue (if no maturity is within three months before or after the remaining life (as defined below), yields for the two published maturities most closely corresponding to the comparable treasury issue will be determined and the treasury rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semiannual equivalent yield to maturity of the comparable treasury issue, calculated using 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. The treasury rate will be calculated on the third business day preceding the date fixed for redemption.

“Comparable Treasury Issue” means the U.S. Treasury security selected by an independent investment banker as having a maturity comparable to the remaining term (“remaining life”) of the Securities of this series 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 such Securities.

The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.
