IN WITNESS WHEREOF, the Issuer has caused this Note to be duly executed under its corporate seal.

This Note is one of a duly authorized issue of % Notes due 20 (the “Notes”) of the Issuer. The Notes are issuable under an indenture, dated as of April 10, 1992 (as amended by the Supplemental Indenture dated as of October 13, 1992, and as supplemented by the Seventh Supplemental Indenture dated as of March 27, 2007, the “Indenture”), each between the Issuer and The Bank of New York (successor to JPMorgan Chase Bank), as trustee (the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities of the Issuer, the Trustee and holders of the Notes and the terms upon which the Notes are, and are to be, authenticated and delivered. The Issuer has appointed The Bank of New York at its principal corporate trust office in The City of New York as the paying agent (the “Paying Agent,” which term includes any additional or successor Paying Agent appointed by the Issuer) with respect to the Notes. The terms of individual Notes may vary with respect to interest rates, interest rate formulas, issue dates, maturity dates or otherwise, all as provided in the Indenture. To the extent not inconsistent herewith, the terms of the Indenture are hereby incorporated by reference herein.

This Note may be redeemed in whole or in part at the option of the Issuer upon payment of the redemption price specified below. If the Issuer exercises the option to redeem this Note, the redemption price will equal the greater of (i) 100% of the principal amount of this Note or (ii) the sum, as determined by the Quotation Agent (defined below), of the present value of the principal amount of this Note and the remaining scheduled payments of interest on this Note from the redemption date to the Maturity Date, exclusive of interest accrued to the redemption date (the “Remaining Life”), discounted from the scheduled payment dates to the redemption date on a semiannual basis (assuming a 360-day year of twelve 30-day months) at the Treasury Rate (defined below) plus basis points, plus accrued and unpaid interest on the principal amount being redeemed to the date of redemption. Notice of redemption shall be mailed to the registered holders of the Notes designated for redemption at their addresses as the same shall appear on the Note register not less than 30 nor more than 60 days prior to the date fixed for redemption, subject to all the conditions and provisions of the Indenture. In the event of redemption of this Note in part only, a new Note or Notes for the amount of the unredeemed portion hereof shall be issued in the name of the holder hereof upon the cancellation hereof.

For purposes of the immediately preceding paragraph, the following defined terms shall have the meanings specified:

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the Remaining Life.

“Comparable Treasury Price” means, with respect to any redemption date, the average of two Reference Treasury Dealer Quotations for such redemption date.

“Quotation Agent” means the Reference Treasury Dealer appointed by the Issuer.

“Reference Treasury Dealer” means each of Citigroup Global Markets Inc. and J.P. Morgan Securities Inc., and their successors; provided, however, that if any of the foregoing ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Issuer will substitute therefor another 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 Trustee, of the bid and asked price for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 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 rate per annum equal to the semiannual yield to maturity of the Comparable Treasury Issue, calculated on the third business day preceding such redemption date 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.

Interest payments on this Note will include interest accrued to but excluding the Interest Payment Dates or the Maturity Date (or any earlier redemption or repayment date), as the case may be. Interest payments for this Note will be computed and paid on the basis of a 360-day year of twelve 30-day months.

In the case where the Interest Payment Date or the Maturity Date (or any redemption or repayment date) does not fall on a Business Day, payment of interest, premium, if any, or principal otherwise payable on such date need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or on the Maturity Date (or any redemption or repayment date), and no interest on such payment shall accrue for the period from and after the Interest Payment Date or the Maturity Date (or any redemption or repayment date) to such next succeeding Business Day.

This Note and all the obligations of the Issuer hereunder are direct, unsecured obligations of the Issuer and rank without preference or priority among themselves and pari passu with all other existing and future unsecured and unsubordinated indebtedness of the Issuer, subject to certain statutory exceptions in the event of liquidation upon insolvency.

This Note, and any Note or Notes issued upon registration of transfer or exchange hereof, is issuable only in fully registered form, without coupons, and is issuable only in denominations of U.S. $2,000 and any integral multiple of U.S. $1,000 in excess thereof.

The Trustee has been appointed registrar for the Notes, and the Trustee will maintain at its principal corporate trust office in The City of New York a register for the registration and transfer of Notes. This Note may be transferred at the aforesaid office of the Trustee by surrendering this Note for cancellation, accompanied by a written instrument of transfer in form satisfactory to the Trustee and duly executed by the registered holder hereof in person or by the holder’s attorney duly authorized in writing, and thereupon the Trustee shall issue in the name of the transferee or transferees, in exchange herefor, a new Note or Notes having identical terms and provisions and having a like aggregate principal amount in authorized denominations, subject to the terms and conditions set forth herein; provided, however, that the Trustee will not be required (i) to register the transfer of or exchange any Note that has been called for redemption in whole or in part, except the unredeemed portion of Notes being redeemed in part, (ii) to register the transfer of or exchange any Note if the holder thereof has exercised his right, if any, to require the Issuer to repurchase such Note in whole or in part, except the portion of such Note not required to be repurchased, or (iii) to register the transfer of or exchange Notes to the extent and during the period so provided in the Indenture with respect to the redemption of Notes. Notes are exchangeable at said office for other Notes of other authorized denominations of equal aggregate principal amount having identical terms and provisions. All such exchanges and transfers of Notes will be free of charge, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge in connection therewith. All Notes surrendered for exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Trustee and executed by the registered holder in person or by the holder’s attorney duly authorized in writing. The date of registration of any Note delivered upon any exchange or transfer of Notes shall be such that no gain or loss of interest results from such exchange or transfer.

In case any Note shall at any time become mutilated, defaced or be destroyed, lost or stolen and such Note or evidence of the loss, theft or destruction thereof (together with the indemnity hereinafter referred to and such other documents or proof as may be required in the premises) shall be delivered to the Trustee, a new Note of like tenor will be issued by the Issuer in exchange for the Note so mutilated or defaced, or in lieu of the Note so destroyed or lost or stolen,

but, in the case of any destroyed or lost or stolen Note, only upon receipt of evidence satisfactory to the Trustee and the Issuer that such Note was destroyed or lost or stolen and, if required, upon receipt also of indemnity satisfactory to each of them. All expenses and reasonable charges associated with procuring such indemnity and with the preparation, authentication and delivery of a new Note shall be borne by the owner of the Note mutilated, defaced, destroyed, lost or stolen.

The Indenture provides that, (a) if an Event of Default (as defined in the Indenture) due to the default in payment of principal of, or interest on, any series of debt securities issued under the Indenture, including the series of Notes of which this Note forms a part, or due to the default in the performance or breach of any other covenant or warranty of the Issuer applicable to the debt securities of such series but not applicable to all outstanding debt securities issued under the Indenture shall have occurred and be continuing, either the Trustee or the holders of not less than 25% in aggregate principal amount of all affected debt securities issued under the Indenture then outstanding (treated as one class) may then declare the principal of all debt securities of all such series and interest accrued thereon to be due and payable immediately and (b) if an Event of Default due to a default in the performance of any other of the covenants or agreements in the Indenture applicable to all outstanding debt securities issued thereunder, including this Note, or due to certain events of bankruptcy, insolvency and reorganization of the Issuer, shall have occurred and be continuing, either the Trustee or the holders of not less than 25% in aggregate principal amount of all debt securities issued under the Indenture then outstanding (treated as one class) may declare the principal of all such debt securities and interest accrued thereon to be due and payable immediately, but upon certain conditions such declarations may be annulled and past defaults may be waived (except a continuing default in payment of principal of, or interest on, such debt securities) by the holders of a majority in principal amount of the debt securities of all affected series then outstanding.

The Indenture permits the Issuer and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the debt securities of all series issued under the Indenture then outstanding and affected (voting as one class), to execute supplemental indentures adding any provisions to or changing in any manner the rights of the holders of each series so affected; provided that the Issuer and the Trustee may not, without the consent of the holder of each outstanding debt security affected thereby, (a) extend the final maturity of any such debt security, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on redemption or repayment thereof, or change the currency of payment thereof, or impair or affect the right of any holder to institute suit for the payment thereof; or (b) reduce the aforesaid percentage in principal amount of debt securities the consent of the holders of which is required for any such supplemental indenture; or (c) modify any of the foregoing provisions except to increase any such percentage or to provide that other provisions cannot be modified or waived without the consent of each affected holder.

So long as this Note shall be outstanding, the Issuer will cause to be maintained an office or agency for the payment of the principal of and premium, if any, and interest on this Note as herein provided in the Borough of Manhattan, The City of New York, and an office or agency in said Borough of Manhattan for the registration, transfer and exchange as aforesaid of the Notes. The Issuer may designate other agencies for the payment of said principal, premium and interest at such place or places (subject to applicable laws and regulations) as the Issuer may decide. So long as there shall be such an agency, the Issuer shall keep the Trustee advised of the names and locations of such agencies, if any are so designated.

With respect to moneys paid by the Issuer and held by the Trustee or any Paying Agent for payment of the principal of or interest or premium, if any, on any Notes that remain unclaimed at the end of two years after such principal, interest or premium shall have become due and payable (whether at maturity or upon call for redemption or otherwise), (i) the Trustee or such Paying Agent shall notify the holders of such Notes that such moneys shall be repaid to the Issuer and any person claiming such moneys shall thereafter look only to the Issuer for payment thereof and (ii) such moneys shall be so repaid to the Issuer. Upon such repayment all liability of the Trustee or such Paying Agent with respect to such moneys shall thereupon cease, without, however, limiting in any way any obligation that the Issuer may have to pay the principal of or interest or premium, if any, on this Note as the same shall become due.

No provision of this Note or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the time, place and rate, and in the coin and currency, herein prescribed unless otherwise agreed between the Issuer and the registered holder of this Note.

Prior to due presentment of this Note for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the holder in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and none of the Issuer, the Trustee or any such agent shall be affected by notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture, or in this Note, or because of the indebtedness evidenced hereby, shall be had against any incorporator, as such, or against any past, present or future stockholder, officer or director, as such, of the Issuer or of any successor, either directly or through the Issuer or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.
