This Note is one of the series designated on the face hereof, limited in aggregate principal amount to $400,000,000. By the terms of the Indenture, additional Notes of this series and of other separate series, which may vary as to date, amount, Stated Maturity, interest rate or method of calculating the interest rate and in other respects as therein provided, may be issued in an unlimited principal amount.

The Company may, at its option, at any time and from time to time, redeem the Notes in whole or in part, on not less than 30 nor more than 60 days’ prior notice mailed to the holders of the Notes. At any time prior to the date that is three months prior to the maturity date of the notes, the Notes will be redeemable at a redemption price, plus accrued and unpaid interest to the date of redemption, equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed or (2) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed that would be due after the related redemption date but for such redemption (except that, if such redemption date is not an interest payment date, the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued thereon 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 Treasury Rate plus 40 basis points. At any time on or after the date that is three months prior to the maturity date of the notes, the notes will be redeemable at a redemption price, plus accrued and unpaid interest to the date of redemption, equal to 100% of the principal amount of the notes being redeemed.

“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 of such Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than six such Reference Treasury Dealer Quotations, the average of all Quotations obtained.

Morgan Securities LLC and Merrill Lynch, Pierce, Fenner and Smith Incorporated, or their respective successors, one primary U.S. government securities dealer located in the United States (a “Primary Treasury Dealer”) selected by Wells Fargo Securities, LLC and two other nationally recognized investment banking firms that are Primary Treasury Dealers specified from time to time by us, except that if any of the foregoing ceases to be a Primary Treasury Dealer, we are required to designate as a substitute another nationally recognized investment banking firm that is a 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 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 the Independent Investment Banker by such Reference Treasury Dealers as of 3:30 p.m., New York City time, on the third business day preceding such redemption date.

Within 30 days following the date upon which the Change of Control Triggering Event occurred with respect to the Notes, or at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company shall send, by first class mail, a notice to each holder of Notes, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer.

The Company shall not be required to make a Change of Control Offer with respect to the Notes if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by us and such third party purchases all the Notes properly tendered and not withdrawn under its offer.

To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached the Company’s obligations under the Change of Control Offer provisions of the notes by virtue of any such conflict.
