Dated:  September 29, 2005

CITIBANK, N.A.
  as Trustee

By:  /s/ John J. Byrnes, Jr.
     -----------------------
     Name: John J. Byrnes, Jr.
     Title:  Authorized Signatory




                                                                               4


                               Reverse of Security

         This Security is one of a duly authorized series of Securities of the
Company designated as Contingently Principal Protected Notes Due September 29,
2008, Linked to the Nikkei 225(SM) Index (herein called the "Securities"). The
Company may, without the consent of the holders of the Securities, create and
issue additional notes ranking equally with the Securities and otherwise similar
in all respects so that such further notes shall be consolidated and form a
single series with the Securities; provided that no additional notes can be
issued if an Event of Default has occurred with respect to the Securities. This
series of Securities is one of an indefinite number of series of debt securities
of the Company, issued and to be issued under an indenture, dated as of
September 1, 1987, as amended (herein called the "Indenture"), duly executed and
delivered by the Company and Citibank N.A., as trustee (herein called 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 description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Company, the Trustee and the Holders of the
Securities.

         The Maturity Payment Amount, at the request of the Trustee, shall be
determined by the Calculation Agent pursuant to the Calculation Agency
Agreement.

         All percentages resulting from any calculation with respect to the
Securities will be rounded at the Calculation Agent's discretion.

         The Trustee shall fully rely on the determination by the Calculation
Agent of the Maturity Payment Amount and shall have no duty to make any such
determination.

         This Security is not subject to any sinking fund.

         If an Event of Default with respect to the Securities shall occur and
be continuing, the amounts payable on all of the Securities may be declared due
and payable in the manner and with the effect provided in the Indenture. The
amount payable to the Holder hereof upon any acceleration permitted under the
Indenture will be equal to the Maturity Payment Amount calculated as though the
date of acceleration was the Stated Maturity Date and the date ten Business Days
prior thereto was the Valuation Date.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than 66 2/3% in aggregate
principal amount of each series of Securities at the time Outstanding to be
affected (each series voting as a class), evidenced as in the Indenture
provided, to execute supplemental indentures adding any provisions to, or
changing in any manner or eliminating any of the provisions of the Indenture or
of any supplemental indenture or modifying in any manner the rights of the
holders of the Securities of all such series; provided, however, that no such
supplemental indenture shall, among other things, (i) change the fixed maturity
of any Security, or reduce the principal amount thereof, or reduce the rate or
extend the time of payment of interest thereon, if any, or reduce any premium
payable on redemption, or make the principal thereof, or premium, if any, or
interest thereon, if any, payable in any coin or currency other than that
hereinabove provided, without the consent of



                                                                               5


the holder of each Security so affected, or (ii) change the place of payment on
any Security, or impair the right to institute suit for payment on any Security,
or reduce the aforesaid percentage of Securities, the holders of which are
required to consent to any such supplemental indenture, without the consent of
the holders of each Security so affected. It is also provided in the Indenture
that, prior to any declaration accelerating the maturity of any series of
Securities, the holders of a majority in aggregate principal amount of the
Securities of such series Outstanding may on behalf of the holders of all the
Securities of such series waive any past default or Event of Default under the
Indenture with respect to such series and its consequences, except a default in
the payment of interest, if any, or the principal of, or premium, if any, on any
of the Securities of such series, or in the payment of any sinking fund
installment or analogous obligation with respect to Securities of such series.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future holders and owners of this
Security and any Securities which may be issued in exchange or substitution
hereof, irrespective of whether or not any notation thereof is made upon this
Security or such other Securities.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal amount with respect to this
Security.

         The Securities are issuable in denominations of $1,000 and any whole
multiples of $1,000.

         The Company, the Trustee, and any agent of the Company or of the
Trustee may deem and treat the registered holder (the "Holder") hereof as the
absolute owner of this Security (whether or not this Security shall be overdue
and notwithstanding any notation of ownership or other writing hereon), for the
purpose of receiving payment hereof, or on account hereof, and for all other
purposes and neither the Company nor the Trustee nor any agent of the Company or
of the Trustee shall be affected by any notice to the contrary. All such
payments made to or upon the order of such registered holder shall, to the
extent of the sum or sums paid, effectually satisfy and discharge liability for
moneys payable on this Security.

         No recourse for the payment of the principal of, premium, if any, or
interest on this Security, or for any claim based hereon or otherwise in respect
hereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto or in any
Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer or director, as
such, past, present or future, of the Company or of any successor corporation,
either directly or through the Company or any successor corporation, whether by
virtue of any constitution, statute or rule of law or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
Corporate Trust Office or agency in a Place of Payment for this Security, duly
endorsed by, or accompanied by a written instrument of transfer in form



                                                                               6

satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Securities of this series or of like tenor and of
authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

         The Company intends to treat, and by purchasing this Security, the
holder agrees to treat, for all tax purposes, this Security as a cash-settled
financial contract giving rise to capital gain or loss, rather than as a debt
instrument.
