<PAGE>

INTEREST

      The Index LASERS do not bear interest. No payments on the Index LASERS
will be made until the Stated Maturity Date.

PAYMENT AT MATURITY

      On the Stated Maturity Date, holders of the Index LASERS will receive for
each Index LASERS the Maturity Payment described below.

DETERMINATION OF THE MATURITY PAYMENT

      The Maturity Payment for each Index LASERS equals the sum of the initial
principal amount of $10 per Index LASERS plus the Index Return Amount.

      The "Index Return Amount" is calculated as follows:

      -     If the Index Return is positive, the Index Return Amount will equal
            the product of:

                  $10 * Upside Participation Rate * Index Return

      -     If the Index Return is negative and

            -     the value of the Dow Jones EURO STOXX 50 Index on any Index
      Business Day after March 24, 2005 up to and including the third Index
      Business Day before the Stated Maturity Date (whether intra-day or at the
      close of trading on any Index Business Day) is less than or equal to
      2,295.50, then the Index Return Amount will equal the product of:

                  $10 * Index Return

            -     the value of the Dow Jones EURO STOXX 50 Index on any Index
      Business Day after March 24, 2005 up to and including the third Index
      Business Day before the Stated Maturity Date (whether intra-day or at the
      close of trading on any Index Business Day) is not less than or equal to
      2,295.50, then the Index Return Amount will be zero.

      -     If the Index Return is zero, the Index Return Amount will be zero.

      The "Index Return" equals:

                          Ending Value - Starting Value
                          -----------------------------
                                 Starting Value

      The "Upside Participation Rate" is 150%.

      The "Starting Value" is 3,060.67, the closing value of the Index on March
      24, 2005.

                                        2
<PAGE>

      The "Ending Value" will be the closing value of the Index on the third
Index Business Day before the Stated Maturity Date.

      If no value (including a closing value) of the Index is available on any
date of determination because of a Market Disruption Event or otherwise, unless
deferred by the calculation agent as described below, the value of the Index
will be the arithmetic mean, as determined by the calculation agent, of the
value of the Index obtained from as many dealers in equity securities (which may
include Citigroup Global Markets Inc. or any of the Company's other subsidiaries
or affiliates), but not exceeding three such dealers, as will make such value
available to the calculation agent. The determination of the value of the Index
by the calculation agent in the event no such closing value is available may be
deferred by the calculation agent for up to two consecutive Index Business Days
on which a Market Disruption Event is occurring.

      An "Index Business Day" means a day, as determined by the calculation
agent, on which the Index or any successor index is calculated and published and
on which securities comprising more than 80% of the value of the Index on such
day are capable of being traded on their relevant exchanges during the one-half
hour before the determination of the closing value of the Index. All
determinations made by the calculation agent will be at the sole discretion of
the calculation agent and will be conclusive for all purposes and binding on the
Company and the beneficial owners of the Index LASERS, absent manifest error.

      A "Market Disruption Event" means, as determined by the calculation agent
in its sole discretion, the occurrence or existence of any suspension of or
limitation imposed on trading (by reason of movements in price exceeding limits
permitted by any relevant exchange or market or otherwise) of, or the
unavailability, through a recognized system of public dissemination of
transaction information, for a period longer than two hours, or during the
one-half hour period preceding the close of trading, on the applicable exchange,
of accurate price, volume or related information in respect of (a) stocks which
then comprise 20% or more of the value of the Index or any successor index, (b)
any options or futures contracts, or any options on such futures contracts
relating to the Index or any successor index, or (c) any options or futures
contracts relating to stocks which then comprise 20% or more of the value of the
value of the Index or any successor index on any exchange or market if, in each
case, in the determination of the calculation agent, any such suspension,
limitation or unavailability is material. For the purpose of determining whether
a Market Disruption Event exists at any time, if trading in a security included
in the Index is materially suspended or materially limited at that time, then
the relevant percentage contribution of that security to the value of the Index
will be based on a comparison of the portion of the value of the Index
attributable to that security relative to the overall value of the Index, in
each case immediately before that suspension or limitation.

DISCONTINUANCE OF THE DOW JONES INDUSTRIAL AVERAGE

      If Dow Jones discontinues publication of the Index or if it or another
entity publishes a successor or substitute index that the calculation agent
determines, in its sole discretion, to be

                                       3
<PAGE>

comparable to the Index, then the value of the Index will be determined by
reference to the value of that index, which is referred to as a "successor
index."

      Upon any selection by the calculation agent of a successor index, the
calculation agent will cause notice to be furnished to the Company and the
Trustee, who will provide notice of the selection of the successor index to the
registered holders of the Index LASERS.

      If Dow Jones discontinues publication of the Index and a successor index
is not selected by the calculation agent or is no longer published on any date
of determination of the value of the index, the value to be substituted for the
Index for that date will be a value computed by the calculation agent for that
date in accordance with the procedures last used to calculate the Index prior to
any such discontinuance.

      If Dow Jones discontinues publication of the Index prior to the
determination of the Index Return Amount and the calculation agent determines
that no successor index is available at that time, then on each Index Business
Day until the earlier to occur of (a) the determination of the Index Return
Amount and (b) a determination by the calculation agent that a successor index
is available, the calculation agent will determine the value that is to be used
in determining the value of the Index. The calculation agent will cause notice
of those daily closing values to be published not less often than once each
month in The Wall Street Journal (or another newspaper of general circulation),
and arrange for information with respect to those values to be made available by
telephone.

      If a successor index is selected or the calculation agent calculates a
value as a substitute for the Index as described above, the successor index or
value will be substituted for the Index for all purposes, including for purposes
of determining whether an Index Business Day or Market Disruption Event occurs.

      All determinations made by the calculation agent will be at the sole
discretion of the calculation agent and will be conclusive for all purposes and
binding on the Company and the beneficial owners of the Index LASERS, absent
manifest error.

ALTERATION OF METHOD OF CALCULATION

      If at any time the method of calculating the Index or a successor index is
changed in any material respect, or if the Index or a successor index is in any
other way modified so that the value of the Index or the successor index does
not, in the opinion of the calculation agent, fairly represent the value of that
index had the changes or modifications not been made, then, from and after that
time, the calculation agent will, at the close of business in New York, New
York, make those adjustments as, in the good faith judgment of the calculation
agent, may be necessary in order to arrive at a calculation of a value of a
stock index comparable to the Index or the successor index as if the changes or
modifications had not been made, and calculate the value of the index with
reference to the Index or the successor index. Accordingly, if the method of
calculating the Index or the successor index is modified so that the value of
the Index or the successor index is a fraction or a multiple of what it would
have been if it had not been modified (e.g., due to a split in the Index), then
the calculation agent will adjust that index in order to arrive at a value of
the index as if it had not been modified (e.g., as if the split had not
occurred).

GENERAL

      This Note is one of a duly authorized issue of debt securities of the
Company (the "Debt Securities"), issued and to be issued in one or more series
under a Senior Debt Indenture, dated as of October 27, 1993, as supplemented by
a First Supplemental Indenture, dated as of November 28, 1997, a Second
Supplemental Indenture, dated as of July 1, 1999, and as further supplemented
from time to time (the "Indenture"), between the Company and The Bank of New
York, as Trustee (the "Trustee", which term includes any successor trustee under
the Indenture), to which Indenture reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the holders of the Index LASERS, and the terms
upon which the Index LASERS are, and are to be, authenticated and delivered.

      If an Event of Default with respect to the Index LASERS shall have
occurred and be continuing, the principal of the Index LASERS may be declared
due and payable in the manner and with the effect provided in the Indenture. In
such case, the amount declared due and payable upon any acceleration permitted
by the Indenture will be determined by the calculation agent and will be equal
to, with respect to this Note, the Maturity Payment calculated as though the
Stated Maturity Date of this Note were the date of early repayment. In case of
default at Maturity of this Note, this Note shall bear interest, payable upon
demand of the beneficial owners of this Note in accordance with the terms
hereof, from and after Maturity through the date when payment of such amount has
been made or duly provided for, at the rate of 5.125% per annum on the unpaid
amount due.

      The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the holders of the Debt Securities of each series to
be affected under the Indenture at any time by the Company and a majority in
aggregate principal amount of the Debt Securities at the time Outstanding of
each series affected thereby. The Indenture also contains provisions permitting
the holders of specified percentages in aggregate principal amount of the Debt
Securities of any series at the time Outstanding, on behalf of the holders of
all Debt Securities of such series, to waive compliance by the Company with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the holder of
this Note shall be conclusive and binding upon such holder and upon all future
holders of this Note and of any Note issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Note.

      The holder of this Note may not enforce such holder's rights pursuant to
the Indenture or the Notes except as provided in the Indenture. No reference
herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company to pay the Maturity Payment with
respect to this Note, and to pay any interest on any overdue amount thereof at
the time, place and rate, and in the coin or currency, herein prescribed.

      All terms used in this Note which are defined in the Indenture but not in
this Note shall have the meanings assigned to them in the Indenture.
