The Notes shall be redeemable in whole or in part at any time and from time to time at the Company’s option. Upon redemption of the Notes, the Company shall pay a Redemption Price equal to the greater of:

(a) 100% of the principal amount of the Notes to be redeemed; or

(b) as determined by a Quotation Agent, the sum of the present values of the Remaining Scheduled Payments of principal and interest thereon (not including any portion of such payments of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate plus 50 basis points, plus accrued and unpaid interest to the Redemption Date.

The following definitions shall apply to the Notes:

“Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual 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.

“Comparable Treasury Issue” means the United States Treasury security selected by a 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 such 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 Quotations, or (2) if the Trustee obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such quotations.

“Quotation Agent” means the Reference Treasury Dealer appointed by the Trustee after consultation with the Company.

“Reference Treasury Dealer” means (1) J.P. Morgan Securities Inc. and its successors; provided, however, that if the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer; and (2) any other Primary Treasury Dealers selected by the Trustee after consultation with the Company.

The Indenture also contains provisions permitting the holders of specified percentages in principal amount of the Notes of each series at the time Outstanding, on behalf of the holders of all Notes of such series, 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 Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note 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 Note.

As provided in and subject to the provisions of the Indenture, the holder of this Note 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 with respect to the Notes of this series, the holders of not less than 25% in principal amount of the Notes of this series at the time Outstanding shall have made written request to the Trustee to institute
