referred to in the within-mentioned Indenture.

Dated: March 31, 2006

CITIBANK, N.A.
as Trustee


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



                                                                               4


                               Reverse of Security

          This Security is one of a duly authorized series of Securities of the
Company designated as Absolute Buffer Notes Due March 31, 2009, 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 three 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 the holder of each Security so
affected, or (ii) change the place of payment on any Security, or



                                                                               5


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
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or



                                                                               6


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.

     obligation toward, or any relationship of agency or trust for or with, any
     of the holders of the Securities;

          (b) unless otherwise specifically provided herein, any order,
     certificate, notice, request, direction or other communication from the

          (e) the Calculation Agent shall incur no liability hereunder except
     for loss sustained by reason of its gross negligence or willful misconduct.

                         [Calculation Agency Agreement]



                                     ANNEX A

     1. The Index.

          The Index is the Nikkei 225(SM) Index (the "Index"), as calculated,
published and disseminated by Nihon Keizai Shimbun, Inc. ("NKS").

     2. Determination of the Maturity Payment Amount.

          The Calculation Agent shall, at the request of the Trustee, determine
the amount payable on the Stated Maturity Date for each $1,000 principal amount
of Securities (the "Maturity Payment Amount").

          The Maturity Payment Amount shall be the following:

          o    If the Final Index Return is zero or positive, $1,000 + ($1,000 x
               the Upside Participation Rate x the Final Index Return).

          o    If the Final Index Return is negative and the Final Index Level
               is equal to or greater than the Threshold Level, $1,000 + ($1,000
               x the absolute value of the Final Index Return).

          o    If the Final Index Return is negative and the Final Index Level
               is less than the Threshold Level, $1,000 + ($1,000 x the Final
               Index Return).

     3. Discontinuance of the Index.

     (a) If NKS discontinues publication of the Index and NKS or another entity
publishes a successor or substitute index (the "Successor Index") that the
Calculation Agent determines, in its sole discretion exercised in good faith, to
be comparable to the discontinued Index, then the Calculation Agent shall
determine each subsequent Closing Index Level to be used in computing the
Maturity Payment Amount by reference to the Closing Index Level of such
Successor Index on the applicable date.

     (b) Upon any selection by the Calculation Agent of a Successor Index, the
Company shall promptly give notice to the holders of the Securities.

     (c) If NKS discontinues publication of the Index and the Calculation Agent
determines that no Successor Index is available at such time, or if NKS (or the
publisher of any Successor Index) fails to calculate and publish a Closing Index
Level for the Index (or a Successor Index) on any date when it would ordinarily
do so in accordance with its customary practice, the Calculation Agent will
determine the Closing Index Level to be used for purposes of computing the
Maturity Payment Amount. In such circumstances, the Closing Index Level will be
computed by the Calculation Agent in accordance with the formula for and method
of calculating the Index (or any Successor Index) last in effect prior to such
discontinuance or failure to publish, using the Closing Index Level (or, if
trading in any of the relevant securities has been materially suspended or
materially limited, its good faith estimate of the Closing Price that would have
prevailed but for such suspension or limitation) on such date of each security
most recently



                                                                               2


comprising the Index (or any Successor Index) on the Relevant Exchange on which
such Security trades.

     4. Alteration of Method of Calculation.

          If at any time the method of calculating the Index, any Successor
Index or the Closing Index Level thereof on any particular day, is changed in a
material respect, or if the Index or a Successor Index is in any other way
modified so that such index does not, in the opinion of the Calculation Agent,
fairly represent the level of the Index or such Successor Index had such changes
or modifications not been made, then, from and after such time, the Calculation
Agent shall, at the Close of Trading of the Relevant Exchanges on which the
securities comprising the Index or such Successor Index traded on any date the
Closing Index Level thereof is to be determined, make such calculations and
adjustments as, in the good faith judgment of the Calculation Agent, may be
necessary in order to arrive at a level of a stock index comparable to the Index
or such Successor Index, as the case may be, as if such changes or modifications
had not been made. The Calculation Agent shall calculate the Closing Index Level
on any particular day and the Maturity Payment Amount with reference to the
Index or such Successor Index, as adjusted.

          Accordingly, if the method of calculating the Index or a Successor
Index is modified so that the level of such index is a fraction of what it would
have been if it had not been modified, then the Calculation Agent shall adjust
such index in order to arrive at a level of the Index or such Successor Index as
if it had not been modified.

     5. Definitions.

          Set forth below are the terms used in the Agreement and in this Annex
