    Title: Authorized Signatory

                                                                               4

                               Reverse of Security

          This Security is one of a duly authorized series of Securities of the
Company designated as Index-Plus Notes Due September 28, 2009, Performance
Linked to S&P 500(R) Index (SPX) (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 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 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
integral 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.

all of which the Company agrees:

          (a) in acting under this Agreement, the Calculation Agent is acting

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

     the Company or the Trustee, as the case may be;

          (c) the Calculation Agent shall be obliged to perform only such duties

          (d) the Calculation Agent, whether acting for itself or in any other

hereinafter provided. The Calculation Agent hereunder may be removed at any time
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

                                                 By: /s/ Karen B. Corrigan
                                                     ---------------------------
                                                     Name:  Karen B. Corrigan
                                                     Title: Vice President

                                     ANNEX A
                                     -------

     1.   The Index.

          The Index is the S&P 500 Index (the "Index"), as calculated, published
and disseminated by Standard & Poor's, a division of McGraw-Hill, Inc. ("S&P").

          The Index is a capitalization-weighted index of 500 stocks designed to
measure performance of the broad domestic economy through changes in the
aggregate market value of 500 stocks representing all major industries. S&P
chooses companies for inclusion in the Index with the aim of achieving a
distribution by broad industry groupings that approximates the distribution of
these groupings in the common stock population of The New York Stock Exchange,
Inc. (the "NYSE"), which S&P uses as an assumed model for the composition of the
total market. As of September 22, 2004, the 500 companies included in the Index
were divided into ten industry groups: Consumer Discretionary, Consumer Staples,
Energy, Financials, Health Care, Industrials, Information Technology, Materials,
Telecommunications Services and Utilities.

     2.   Determination of the Maturity Payment Amount.

          The Calculation Agent shall determine the amount payable at Stated
Maturity 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 Level is greater than or equal to the Initial
               Index Level, the sum of:

               (1)  $1,000; and

                                                 Final Index       Initial Index
                                  Upside            Level      -       Level
               (2)  $1,000  x  Participation  x  -------------------------------
                                   Rate                Initial Index Level

          o    If the Final Index Level is less than the Initial Index Level and
               the Closing Level of the Index is at or above the Threshold Level
               on all Exchange Business Days during the Measurement Period,
               $1,000.

          o    If the Final Index Level is less than the Initial Index Level and
               the Closing Level of the Index has fallen below the Threshold
               Level on any Exchange Business Day during the Measurement Period,
               the product of:

               (1)  $1,000; and

                     Final Index Level
               (2)  -------------------
                    Initial Index Level

                                                                               2

     3.   Discontinuance of the Index.

     (a) If S&P discontinues publication of the Index and S&P 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
calculate the Maturity Payment Amount pursuant to Section 2 hereof by reference
to the index level of such Successor Index at the Close of Trading on the NYSE,
AMEX, Nasdaq or the relevant exchange or market for the Successor Index on the
Valuation 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 S&P discontinues publication of the Index prior to, and such
discontinuance is continuing on, the Valuation Date and the Calculation Agent
determines that no Successor Index is available at such time, or if S&P fails to
calculate and announce a Closing Level for the Index on the Valuation Date,
then, on such date, the Calculation Agent shall determine the index to be used
in computing the Maturity Payment Amount. The Maturity Payment Amount shall be
computed by the Calculation Agent in accordance with the formula for and method
of calculating the Index last in effect prior to such discontinuance, using the
Closing Level (or, if trading in the relevant securities has been materially
suspended or materially limited, its good faith estimate of the Closing Level
that would have prevailed but for such suspension or limitation) at the close of
the principal trading session on such date of each security most recently
comprising the Index on the primary organized U.S. exchange or trading system.

     4.   Alteration of Method of Calculation.

          If at any time the method of calculating the Index or a Successor
Index, or the Closing Level thereof, 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 value of the
Index or such Successor Index had such changes or modifications not been made,
then, from and after such time, the Calculation Agent will, at the Close of
Trading in New York City on the Valuation Date, 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, and calculate 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 (for
example, due to a split in the index), 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 (for example, if such split had not occurred).

     market fluctuations imposed pursuant to NYSE Rule 80B or any applicable

                                                                               4

     primary exchange or quotation system on which those futures or options
     contracts are traded, at any time during the one-hour period that ends at

     ability of market participants in general to effect transactions in, or
     obtain market values for, the futures or options contracts relating to the

     its obligations with respect to the Securities.

     For purposes of determining whether a Market Disruption Event has occurred
     the relevant percentage contribution of a security to the level of the
     Index or any Successor Index will be based on a comparison of (x) the
     portion of the level of the Index attributable to that security and (y) the
     overall level of the Index, in each case immediately before the occurrence
     of the Market Disruption Event.

                                                                               5
