   Name: Wafaa Orfy
   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 July 29, 2008, Linked to the Dow
Jones EURO STOXX 50(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

                                                                               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 financial
contract for cash settlement, rather than as a debt instrument.

Trustee's request, be made available at the Corporate Trust Office.

         4. Fees and Expenses. The Calculation Agent shall be entitled to
reasonable compensation for all services rendered by it as agreed to between the
Calculation Agent and the Company.

         5. Terms and Conditions. The Calculation Agent accepts its obligations
herein set out upon the terms and conditions hereof, including the following, to
all of which the Company agrees:

         (a) in acting under this Agreement, the Calculation Agent is acting
     solely as an independent expert of the Company and does not assume any
     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
     Company or the Trustee made or given under any provision of this Agreement
     shall be sufficient if signed by any person whom the Calculation Agent
     reasonably believes to be a duly authorized officer or attorney-in-fact of
     the Company or the Trustee, as the case may be;

         (c) the Calculation Agent shall be obliged to perform only such duties
     as are set out specifically herein and any duties necessarily incidental
     thereto;

         (d) the Calculation Agent, whether acting for itself or in any other
     capacity, may become the owner or pledgee of Securities with the same
     rights as it would have had if it were not acting hereunder as Calculation
     Agent; and

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

         6. Resignation; Removal; Successor. (a) The Calculation Agent may at
any time resign by giving written notice to the Company of such intention on its
part, specifying the date on which its desired resignation shall become
effective, subject to the appointment of a successor Calculation Agent and
acceptance of such appointment by such successor Calculation Agent, as
hereinafter provided. The Calculation Agent hereunder may be removed at any time

                                                                               3

by the filing with it of an instrument in writing signed by or on behalf of the
Company and specifying such removal and the date when it shall become effective.
Such resignation or removal shall take effect upon the appointment by the
Company, as hereinafter provided, of a successor Calculation Agent and the
acceptance of such appointment by such successor Calculation Agent. In the event
a successor Calculation Agent has not been appointed and has not accepted its
duties within 90 days of the Calculation Agent's notice of resignation, the
Calculation Agent may apply to any court of competent jurisdiction for the
designation of a successor Calculation Agent.

         (b) In case at any time the Calculation Agent shall resign, or shall be
removed, or shall become incapable of acting, or shall be adjudged bankrupt or
insolvent, or make an assignment for the benefit of its creditors or consent to
the appointment of a receiver or custodian of all or any substantial part of its
property, or shall admit in writing its inability to pay or meet its debts as
they mature, or if a receiver or custodian of it or all or any substantial part
of its property shall be appointed, or if any public officer shall have taken
charge or control of the Calculation Agent or of its property or affairs, for
the purpose of rehabilitation, conservation or liquidation, a successor
Calculation Agent shall be appointed by the Company by an instrument in writing,
filed with the successor Calculation Agent. Upon the appointment as aforesaid of
a successor Calculation Agent and acceptance by the latter of such appointment,
the Calculation Agent so superseded shall cease to be Calculation Agent
hereunder.

         (c) Any successor Calculation Agent appointed hereunder shall execute,
acknowledge and deliver to its predecessor, to the Company and to the Trustee an
instrument accepting such appointment hereunder and agreeing to be bound by the
terms hereof, and thereupon such successor Calculation Agent, without any
further act, deed or conveyance, shall become vested with all the authority,
rights, powers, trusts, immunities, duties and obligations of such predecessor
with like effect as if originally named as Calculation Agent hereunder, and such
predecessor, upon payment of its charges and disbursements then unpaid, shall
thereupon become obligated to transfer, deliver and pay over, and such successor
Calculation Agent shall be entitled to receive, all moneys, securities and other
property on deposit with or held by such predecessor, as Calculation Agent
hereunder.

merged or converted or any corporation with which the Calculation Agent may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Calculation Agent shall be a party, or any
corporation to which the Calculation Agent shall sell or otherwise transfer all
or substantially all of the assets and business of the Calculation Agent shall
be the successor Calculation Agent under this Agreement without the execution or
filing of any paper or any further act on the part of any of the parties hereto.

A hereto are used herein as defined in the Indenture or the Securities.

         8. Indemnification. The Company will indemnify the Calculation Agent

                                                 -------------------------------

                         [Calculation Agency Agreement]

                                     ANNEX A
                                     -------

     1.   The Index.

          The Index is the Dow Jones EURO STOXX 50(SM) Index (the "Index"), as
calculated, published and disseminated by STOXX Limited ("STOXX").

     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 not negative, $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 STOXX discontinues publication of the Index and STOXX 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 STOXX discontinues publication of the Index and the Calculation
Agent determines that no Successor Index is available at such time, or if STOXX
(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

                                                                               2

most recently 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.
