This Note is one of the securities of the series designated on the face hereof.

DEFINITIONS

The following terms, as used herein, have the following meanings unless the context or use clearly indicates another or different meaning or intent:

“Business Day” means any day other than (i) a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulations to close in the City of New York, or (ii) a day on which the Corporate Trust Office of the Trustee is closed for business.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term (as measured from the date of redemption) of the Notes to be redeemed (the “Remaining Life”) that would be used, 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 Life of the Notes.

“Comparable Treasury Price” means with respect to any redemption date (1) the average of five Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if an Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Depositary” shall mean The Depository Trust Company or any successor depositary.

“Independent Investment Banker” means Wells Fargo Securities, LLC, Morgan Stanley & Co. LLC, MUFG Securities Americas, Inc., or any of their respective successors, as designated by the Company, or if all of those firms are unwilling or unable to serve as such, an independent investment and banking institution of national standing selected by the Company.

“Interest Payment Date” means each of the dates on which interest on this Note is payable, which dates are set forth on the face of this Note.

“Par Call Date” means the date set forth on the face of this Note identified as the Par Call Date.

“Person” means any individual, corporation, partnership, limited liability company, joint venture, association, joint-stock company, trust, unincorporated organization or government or any agency or political subdivision of any government.

“Record Date” means the fifteenth calendar day (whether or not a Business Day) immediately preceding the related Interest Payment Date, provided, however, as long as the Notes are registered in the name of the Depositary, its nominee or a successor depositary, the Record Date shall be the close of business on the Business Day immediately preceding the Interest Payment Date. The Record Date shall constitute the Regular Record Date for purposes of the Original Indenture.

“Reference Treasury Dealer” means (i) a primary treasury dealer selected by Wells Fargo Securities, LLC, , Morgan Stanley & Co. LLC, MUFG Securities Americas, Inc., or each of their respective affiliates and successors; provided that if any such Reference Treasury Dealer ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute another Primary Treasury Dealer; and (ii) up to two Primary Treasury Dealers selected by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by an Independent Investment Banker, 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 an Independent Investment Banker at 3:30 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 yield determined by the Company as follows:

(i) The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

6

(ii) If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

INTEREST RATE

This Note will bear interest at the rate per annum (computed based on a 360-day year consisting of twelve 30-day months) identified on the face of this Note. Except for the effect of any adjustment in the Interest Payment Date as provided in the following sentence, the amount of interest payable for any period shorter than a full six-month period for which interest is computed, will be computed on the basis of the actual number of days elapsed in such a 180-day period. If any Interest Payment Date would otherwise be a day that is not a Business Day, the payment required to be made on such Interest Payment Date will be postponed to the next succeeding Business Day, and no interest will accrue on such payment for the period from and after such Interest Payment Date to the date of such payment on the next succeeding Business Day.

OPTIONAL REDEMPTION

Prior to the Par Call Date, the Notes are subject to redemption, in whole or in part, at any time, at the option of the Company, at a redemption price equal to the greater of:

(i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points (0.15%), less (b) interest accrued to the date of redemption, and

(ii) 100% of the principal amount of the Notes to be redeemed,

plus, in either of the above cases, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed (or delivered by electronic transmission in accordance with the applicable procedures of the Depositary) at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed.

In the case of a partial redemption, selection of the Notes for redemption will be made in accordance with the applicable procedures of the Depositary. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. The Note shall be reduced by the Trustee in an amount equal to the principal amount of such Note being redeemed in accordance with the applicable procedures of the Depositary. For so long as the Notes are held by the Depositary, the redemption of the Notes shall be done in accordance with the policies and procedures of the Depositary.

Unless the Company 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 are not entitled to the benefit of any sinking fund or analogous provision.
