Annex II-3

(REVERSE OF SECURITY)

This Security is one of a duly authorized issue of securities of the Corporation (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of February 23, 2000 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Corporation and U.S. Bank National Association, as successor trustee to U.S. Bank Trust National Association (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitation of rights, duties and immunities thereunder of the Corporation, the Trustee 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 (subject to exceptions provided in the Indenture) in aggregate principal amount to $                    .

All or a portion of the Securities of this series may be redeemed at the Corporation’s option at any time or from time to time at a Redemption Price calculated as provided below.

The Redemption Price for the Securities of this series to be redeemed on any Redemption Date will be equal to the greater of the following amounts: (a) 100% of the principal amount of the Securities being redeemed on that Redemption Date; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities being redeemed on that Redemption Date (not including any portion of any payments of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the Adjusted Treasury Rate (as defined below) plus 20 basis points, as determined by the Independent Investment Banker (as defined below), plus, in each case, accrued and unpaid interest on the Securities to be redeemed to the Redemption Date. Notwithstanding the foregoing, installments of interest on Securities of this series that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date will be payable on that Interest Payment Date to the Holders of such Securities as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date, according to the Securities of this series and Indenture. The Redemption Price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

The Corporation will mail notice of any redemption at least 30 days but not more than 60 days before the Redemption Date to each Holder of the Securities of this series to be redeemed. Once notice of redemption is mailed, the Securities of this series called for redemption will become due and payable on the Redemption Date at the applicable Redemption Price, plus accrued and unpaid interest to the Redemption Date, and will be paid upon surrender thereof for redemption. If the Corporation elects to redeem all or a portion of the Securities of this series, that redemption will not be conditional upon receipt by the Paying Agent or the Trustee of monies sufficient to pay the Redemption Price.

Unless the Corporation defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

“Adjusted 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.

“Comparable Treasury Issue” means, with respect to any Redemption Date, the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the

Annex II-4

remaining term 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.

“Comparable Treasury Price” means, with respect to any Redemption Date, (A) the average of the Reference Treasury Dealer Quotations for such Redemption Date or (B) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means, with respect to any Redemption Date, one of the Reference Treasury Dealers appointed by the Corporation to act as the “Independent Investment Banker.”

“Reference Treasury Dealer” means, with respect to any Redemption Date, (A) J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and a Primary Treasury Dealer (as defined herein) selected by Wells Fargo Securities, LLC (or their respective affiliates which are Primary Treasury Dealers), and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Corporation will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Corporation.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Corporation, 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 Corporation by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day preceding such Redemption Date. As used in the preceding sentence, “Business Day” means any day (other than a Saturday or Sunday) on which banking institutions in the City of New York are not authorized or obligated by law or executive order to remain closed.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor in an aggregate principal amount equal to the unredeemed portion of the principal hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to the Securities of this series shall occur and be continuing, the principal of and accrued and unpaid interest on the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Corporation and the rights of the Holders of the Securities of each series affected under the Indenture at any time by the Corporation and the Trustee with the consent of the Holders of a majority in principal amount of the Securities of each series at the time Outstanding affected thereby. The Indenture contains provisions permitting the Holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding with respect to which a default under the Indenture shall have occurred and be continuing, on behalf of the Holders of all Securities of such series, to waive, with certain exceptions, such past default with respect to such series and its consequences. The Indenture also permits the Holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Corporation with certain provisions of the Indenture. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and

Annex II-5

upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security 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 Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee, such Holder or Holders shall have offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and the Trustee shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. 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.

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

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Corporation may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
