[BACK OF NOTE]





     This Note is one of a duly authorized issue of [ ]% Series [A] [B] Notes due ___(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 further amended
by the Sixth Supplemental Indenture dated as of November 14, 2005, the “Indenture”), each
between the Issuer and JPMorgan Chase Bank, N.A. (successor to Manufacturers Hanover Trust
Company), 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 JPMorgan Chase Bank, N.A., 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.



     If so indicated on the face of this Note, 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 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 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 with the Remaining Life.



A-4








     “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 J.P. Morgan Securities Inc. and Citigroup Global
Markets 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.



A-5








     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 or the Trustee 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



A-6










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
