MERRILL LYNCH & CO., INC.
8% Callable STock Return Income DEbt Securities/SM/
due March 15, 2004
Payable at maturity with Corning Incorporated common stock
("Callable STRIDES/SM/")

Merrill Lynch & Co., Inc., a Delaware corporation (hereinafter referred to
as the "Company", which term includes any successor corporation under the
Indenture herein referred to), for value received, hereby promises to pay to
CEDE & CO., or its registered assigns, if not previously called, for each Unit
interest at a rate of 8% per year payable quarterly in arrears on March 15, June
15, September 15 and December 15 of each year beginning June 15, 2002. On March
15, 2004 (the "Stated Maturity"), if not called on or prior to the Stated
Maturity, the Company hereby promises to pay to CEDE & CO., or its registered
assigns, for each Unit any accrued and unpaid interest plus one share of Corning
Incorporated ("Corning") common stock, subject to adjustment for certain
corporate events relating to Corning as described below. If the Callable STRIDES
are called by the Company, the Company hereby promises to pay to CEDE & CO., or
its registered assigns, for each Unit any accrued and unpaid interest plus the
Call Price, as defined below, on the Call Date, as defined below.

1


Payment or delivery of interest, Corning common stock, the Call Price, and
any interest on any overdue amount thereof with respect to this Security shall
be made at the office or agency of the Company maintained for that purpose in
the Borough of Manhattan, The City of New York, in such coin or currency of the
United States of America, if applicable, as at the time of payment is legal
tender for payment of public and private debts.

This Callable STRIDES Security is one of the series of 8% Callable STock
Return Income DEbt Securities/SM/ due March 15, 2004, payable at maturity with
Corning Incorporated common stock.

Interest

The Company will pay interest on the Callable STRIDES at a rate of 8% per
year on the principal amount represented by this Callable STRIDES Security from
March 15, 2002, or from the most recent Interest Payment Date, as defined below,
for which interest has been paid or provided for, to but excluding the Stated
Maturity or Call Date, as applicable. Interest will be paid on the Callable
STRIDES in cash quarterly in arrears on March 15, June 15, September 15 and
December 15 of each year (each such date being an "Interest Payment Date") and
on the Stated Maturity or Call Date, as applicable, beginning June 15, 2002.
Interest on the Callable STRIDES will be computed on the basis of 360-day year
of twelve 30-day months. If an Interest Payment Date falls on a day that is not
a Business Day, that interest payment will be made on the next Business Day with
no additional interest accruing as a result of the delayed payment.

Payment at the Stated Maturity

If the Company does not call the Callable STRIDES on or prior to the Stated
Maturity then on the Stated Maturity each Unit will be entitled to receive a
cash payment equal to any accrued and unpaid interest plus one share of Corning
common stock or the Reorganization Event Amount, as applicable; however, if the
Share Multiplier, as defined below, is more or less than one (1), due to certain
corporate events, as described below, then each Holder of a Unit will receive
the number of shares equal to the Share Multiplier. The Company will not
distribute any fractional shares of Corning common stock. If the Share
Multiplier is adjusted to account for certain corporate events, as described
below, and the number of shares to be delivered on the Stated Maturity is not
divisible by a whole number, the Company will aggregate all share amounts due to
the Holder on the Stated Maturity and in lieu of delivering a fractional share
at the Stated Maturity, will instead pay to the Holder an amount equal to the
cash value of the fractional share based upon the Closing Market Price, as
defined below, of Corning common stock. If the Stated Maturity is not a Business
Day, each Unit shall receive the Corning common stock and any accrued and unpaid
interest or other amounts due on the next Business Day with no additional
interest accruing as a result of the delayed payment.

Payment at the Call Date

If the Company chooses to call the Callable STRIDES on or prior to the
Stated Maturity each Unit will be entitled to receive the Call Price plus any
accrued and unpaid interest on the

2


Call Date. The Company may call the Callable STRIDES, in whole but not in part,
on any Business Day beginning on March 17, 2003 to and including the Stated
Maturity (any such date being the "Call Date") by giving notice to the Trustee,
as defined below, at least 10 Business Days prior to the Call Date. Such notice
will specify the Call Date, Call Price and the amount of accrued and unpaid
interest payable on the Call Date. The Call Price is an amount, per each Unit of
the Callable STRIDES, that when discounted from the Call Date to March 15, 2002
by a discount factor based on an annual yield to call of 36% and added to the
present value of all interest payments made through and including the Call Date
discounted to March 15, 2002 by that same discount factor, will equal $8.90.

"Business Day" means each Monday, Tuesday, Wednesday, Thursday and Friday
that is not a day on which banking institutions in The City of New York are
authorized or obligated by law to close and with respect to the Stated Maturity
is also a day that is a Trading Day.

"Trading Day" means a day on which the New York Stock Exchange (the
"NYSE"), the American Stock Exchange and the Nasdaq Stock Market are open for
trading as determined by the Calculation Agent.

"Share Multiplier" initially means 1.0, but is subject to adjustment due to
certain corporate events described below.

The "Calculation Agent" for all purposes related to the Callable STRIDES
shall be Merrill Lynch, Pierce, Fenner & Smith Incorporated. All determinations
made by the Calculation Agent shall be at the sole discretion of the Calculation
Agent and, absent a determination by the Calculation Agent of a manifest error,
shall be conclusive for all purposes and binding on the Company and the Holders
and beneficial owners of the Callable STRIDES.

Adjustments to the Share Multiplier; Market Disruption Events

No adjustments to the Share Multiplier will be required unless the Share
Multiplier adjustment would require a change of at least 0.1% in the Share
Multiplier then in effect. The Share Multiplier resulting from any of the
adjustments specified below will be rounded to the nearest one thousandth with
five ten-thousandths being rounded upward. The Calculation Agent will not be
required to make any adjustments to the Share Multiplier after the close of
business on the fourth Business Day immediately prior to the maturity date or
early redemption date, as applicable.

No adjustments to the Share Multiplier will be required other than those
specified below. However, the Calculation Agent may, at its sole discretion,
make additional adjustments to the Share Multiplier to reflect changes occurring
in relation to Corning common stock or any other security received in a
Reorganization Event, as defined below, in other circumstances where the
Calculation Agent determines that it is appropriate to reflect those changes to
ensure an equitable result.

3


The Calculation Agent shall be solely responsible for the determination and
calculation of any adjustments to the Share Multiplier and of any related
determinations and calculations with respect to any distributions of stock,
other securities or other property or assets, including cash, in connection with
any corporate event described below; and its determinations and calculations
shall be conclusive absent manifest error.

No adjustments will be made for certain other events, such as offerings of
common stock by Corning for cash or in connection with the occurrence of a
partial tender or exchange offer for Corning common stock by Corning

The Company will, within ten Business Days following the occurrence of an
event that requires an adjustment to the Share Multiplier, or, if later, within
ten Business Days following the date on which the Company becomes aware of this
occurrence, provide written notice to the Trustee, which shall provide notice to
the Holders of the Callable STRIDES of the occurrence of this event and a
statement in reasonable detail setting forth the adjusted Share Multiplier.

Stock splits and reverse stock splits

If Corning common stock is subject to a stock split or reverse stock split,
then once any split has become effective, the Share Multiplier relating to
Corning common stock will be adjusted to equal the product of the prior Share
Multiplier and the number of shares which a holder of one share of Corning
common stock before the effective date of that stock split or reverse stock
split would have owned or been entitled to receive immediately following the
applicable effective date.

Stock dividends

If Corning common stock is subject (i) to a stock dividend that is given
ratably to all holders of shares of Corning common stock or (ii) to a
distribution of shares of Corning common stock as a result of the triggering of
any provision of the corporate charter of Corning, then once the dividend has
become effective and the shares are trading ex-dividend, then the Share
Multiplier will be adjusted so that the new Share Multiplier shall equal the
prior Share Multiplier plus the product of:

. the number of shares of Corning common stock issued with respect to one
share of Corning common stock, and

. the prior Share Multiplier.

Extraordinary Dividends

There will be no adjustments to the Share Multiplier to reflect any cash
dividends or cash distributions paid with respect to Corning common stock other
than Extraordinary Dividends, as described below, and distributions described
under the section entitled Reorganization Events below.

4


An "Extraordinary Dividend" means, with respect to a cash dividend or
other distribution with respect to Corning common stock, a dividend or other
distribution which exceeds the immediately preceding non-Extraordinary Dividend
for Corning common stock (as adjusted for any subsequent corporate event
requiring an adjustment hereunder) by an amount equal to at least 10% of the
Closing Market Price of Corning common stock on the Trading Day preceding the
ex-dividend date with respect to the Extraordinary Dividend (the "Ex-Dividend
Date"). If an Extraordinary Dividend occurs with respect to Corning common
stock, the Share Multiplier will be adjusted on the Ex-Dividend Date with
respect to the Extraordinary Dividend so that the new Share Multiplier will
equal the product of:

. the prior Share Multiplier, and

. a fraction, the numerator of which is the Closing Market Price
per share of Corning common stock on the Trading Day preceding
the Ex-Dividend Date, and the denominator of which is the amount
by which the Closing Market Price on the Trading Day preceding
the Ex-Dividend Date exceeds the Extraordinary Dividend Amount.

The "Extraordinary Dividend Amount" with respect to an Extraordinary
Dividend for Corning common stock will equal:

. in the case of cash dividends or other distributions that
constitute quarterly dividends, the amount per share of that
Extraordinary Dividend minus the amount per share of the
immediately preceding non-Extraordinary Dividend for such shares
of Corning common stock, or

. in the case of cash dividends or other distributions that do not
constitute quarterly dividends, the amount per share of that
Extraordinary Dividend.

To the extent an Extraordinary Dividend is not paid in cash, the value
of the non-cash component will be determined by the Calculation Agent, whose
determination shall be conclusive. A distribution on Corning common stock
described in clause (a), (d) or (e) of the section entitled Reorganization
Events below that also constitutes an Extraordinary Dividend shall only cause an
adjustment pursuant to clause (a), (d) or (e) under the section entitled
Reorganization Events. A distribution on Corning common stock described in the
section entitled Issuance of transferable rights and warrants that also
constitutes an Extraordinary Dividend shall only cause an adjustment pursuant to
such section.

"Closing Market Price" means if Corning common stock (or any other
security for which a Closing Market Price must be determined for purposes of
this Callable STRIDES) is listed on a national securities exchange in the United
States, is a Nasdaq National Market System ("Nasdaq NMS") security or is
included in the OTC Bulletin Board Service ("OTC Bulletin Board") operated by
the National Association of Securities Dealers, Inc. (the "NASD"), then the
Closing Market Price for any date of determination on any Trading Day means for
one share of Corning

5


common stock (or any other security for which a Closing Market Price must be
determined for purposes of the Callable STRIDES):

. the last reported sale price, regular way, on that day on the
principal United States securities exchange registered under the
Securities Exchange Act of 1934, as amended, on which that
security is listed or admitted to trading (without taking into
account any extended or after-hours trading session), or

. if not listed or admitted to trading on any such securities
exchange or if the last reported sale price is not obtainable,
the last reported sale price on the over-the-counter market as
reported on the Nasdaq NMS or OTC Bulletin Board on that day
(without taking into account any extended or after-hours trading
session), or

. if the last reported sale price is not available for any reason,
including, without limitation, the occurrence of a Market
Disruption Event, as described below, the mean of the last
reported bid and offer price of the principal trading session on
the over-the-counter market as reported on the Nasdaq Stock
Market or OTC Bulletin Board on that day as determined by the
Calculation Agent or from as many dealers in such security, but
not exceeding three, as have made the bid prices available to the
Calculation Agent after 3:00 p.m., local time in the principal
market, on that date (without taking into account any extended or
after-hours trading session).

If Corning common stock (or any other security for which a Closing Market
Price must be determined for purposes of the Callable STRIDES) is not listed on
a national securities exchange in the United States, is not a Nasdaq NMS
security or included in the OTC Bulletin Board, then the Closing Market Price
for any date of determination on any Trading Day means for one share of Corning
common stock (or any other security for which a Closing Market Price must be
determined for purposes of the Callable STRIDES) the last reported sale price on
that day on the securities exchange on which that security is listed or admitted
to trading with the greatest volume of trading for the calendar month preceding
such Trading Day as determined by the Calculation Agent; provided that if such
last reported sale price is for a transaction which occurred more than four
hours prior to the close of that exchange, then the Closing Market Price shall
mean the average (mean) of the last available bid and offer price on that
exchange.

If Corning common stock (or any other security for which a Closing Market
Price must be determined for purposes of the Callable STRIDES) is not listed or
admitted to trading on any such securities exchange or if such last reported
sale price or bid and offer are not obtainable, then the Closing Market Price
shall mean the average (mean) of the last available bid and offer prices in such
market of the three dealers which have the highest volume of transactions in
that security in the immediately preceding calendar month as determined by the
Calculation Agent based on information that is reasonably available to it.

6


"Market Disruption Event" means:

(1) a suspension of, absence of, including the absence of an official
closing price, or material limitation on, trading of Corning
common stock on the primary market for Corning common stock for
more than two hours of trading or during the one-half hour period
preceding the close of trading, as determined by the Calculation
Agent in its sole discretion; or the suspension or material
limitation on the primary market for trading in options contracts
related to Corning common stock, if available, during the
one-half hour period preceding the close of trading in the
applicable market, in each case as determined by the Calculation
Agent in its sole discretion; and

(2) a determination by the Calculation Agent in its sole discretion
that the event described in clause (1) above materially
interfered with the ability of the Company, the Calculation Agent
or any of their affiliates to unwind all or a material portion of
the hedge with respect to these Callable STRIDES.

For purposes of determining whether a Market Disruption Event has
occurred:

(1) a limitation on the hours or number of days of trading will not
constitute a Market Disruption Event if it results from an
announced change in the regular business hours of the relevant
exchange,

(2) a decision to permanently discontinue trading in the relevant
options contracts related to Corning common stock will not
constitute a Market Disruption Event,

(3) limitations pursuant to any rule or regulation enacted or
promulgated by the NYSE or the Nasdaq Stock Market or other
regulatory organization with jurisdiction over the NYSE or the
Nasdaq Stock Market on trading during significant market
fluctuations will constitute a suspension or material limitation
of trading in Corning common stock,

(4) a suspension of trading in an options contract on Corning common
stock by the primary securities market trading in the options
contracts related to Corning common stock, if available, by
reason of:

. a price change exceeding limits set by the securities
exchange or market,

. an imbalance of orders relating to the options contracts on
Corning common stock, or

. a disparity in bid and ask quotes relating to options
contracts on Corning common stock

7


will constitute a suspension or material limitation of trading in
options contracts related to Corning common stock, and

(5) a suspension, absence or material limitation of trading on the
primary securities market on which options contracts related to
Corning common stock are traded will not include any time when
that securities market is itself closed for trading under
ordinary circumstances.

If the Exchange Property, as defined below, includes securities other
than Corning common stock, then the above definition shall be revised to include
each such security in the same manner as Corning common stock is considered in
determining whether a Market Disruption Event exists.

Issuance of transferable rights or warrants

If Corning issues transferable rights or warrants to all holders of
Corning common stock to subscribe for or purchase Corning common stock,
including new or existing rights to purchase Corning common stock pursuant to a
shareholder's rights plan or arrangement, then the Share Multiplier will be
adjusted on the Business Day immediately following the issuance of such
transferable rights or warrants so that the new Share Multiplier shall equal the
prior Share Multiplier plus the product of:

. the prior Share Multiplier, and

. the number of shares of Corning common stock that can be
purchased with the cash value of such warrants or rights
distributed on a single share of Corning common stock.

The number of shares that can be purchased will be based on the Closing Market
Price of Corning common stock on the date the new Share Multiplier is
determined. The cash value of such warrants or rights, if the warrants or rights
are traded on a national securities exchange, will equal the closing price of
such warrant or right, or, if the warrants or rights are not traded on a
national securities exchange, will be determined by the Calculation Agent and
will equal the average (mean) of the bid prices obtained from three dealers at 3
p.m. on the date the new Share Multiplier is determined, provided that if only
two such bid prices are available, then the cash value of such warrants or
rights will equal the average (mean) of such bids and if only one such bid is
available, then the cash value of such warrants or rights will equal such bid.

Reorganization Events

If prior to the Stated Maturity of the Callable STRIDES,

8


(a) there occurs any reclassification or change of Corning
common stock, including, without limitation, as a result
of the issuance of tracking stock by Corning,

(b) Corning, or any surviving entity or subsequent surviving
entity of Corning (a "Successor Entity"), has been subject
to a merger, combination or consolidation and is not the
surviving entity,

(c) any statutory exchange of securities of Corning or any
Successor Entity with another corporation occurs, other
than pursuant to clause (b) above,

(d) Corning is liquidated or is subject to a proceeding under
any applicable bankruptcy, insolvency or other similar
law,

(e) Corning issues to all of its shareholders equity
securities of an issuer other than Corning, other than in
a transaction described in clauses (b), (c) or (d) above
(a "Spin-off Event"), or

(f) a tender or exchange offer or going-private transaction is
consummated for all the outstanding shares of Corning (an
event in clauses (a) through (f) a "Reorganization
Event"),

then the method of determining the amount payable on each Callable STRIDES will
be adjusted as set forth below. "Exchange Property" will consist of the
securities, cash or any other assets distributed to holders of Corning common
stock in or as a result of the Reorganization Event, and where Corning common
stock continues to be held by the holders receiving such distribution, the
Corning common stock. The Exchange Property will either:

A. be delivered at the Stated Maturity to the Holders of the Callable
STRIDES in an amount per Unit equal to the amount of Exchange
Property delivered with respect to the number of shares of Corning
common stock equal to the Share Multiplier at the time of the
Reorganization Event, or

B. at the option of the Calculation Agent, the Exchange Property will
be liquidated and the cash proceeds will be paid to the Holders of
the Callable STRIDES as described below.

If the Exchange Property received in a Reorganization Event:

. consists only of cash or if the Calculation Agent exercises its
option to liquidate the Exchange Property following its
distribution, then, unless the Company exercises its right to
call the Callable STRIDES, the Callable STRIDES will be
redeemed: (i) in the case where the Exchange Property delivered
to the holders of Corning common stock consists of cash only,

9


on the third Business Day succeeding the day on which that cash is
distributed to holders of Corning common stock, or (ii) in the case
where the Exchange Property is liquidated, on the date specified by
the Company as described below, and Holders of the Callable STRIDES
will receive, in lieu of any Corning common stock and in full
satisfaction of the Company's obligations under the Callable
STRIDES, the lesser of:

(i) the product of (a) the amount of cash received with respect
to one share of Corning common stock and the then current
Share Multiplier, or (b) the value of the Exchange Property
liquidated with respect to one share of Corning common stock
and the then current Share Multiplier, as applicable, plus in
either case accrued and unpaid interest to the early
redemption date, and

(ii) the Call Price calculated as though the early redemption date
were the Call Date (regardless of whether the early
redemption date is a day which occurs prior to March 17,
2003) plus accrued and unpaid interest to the early
redemption date, in each case, no interest will accrue on the
Callable STRIDES following the early redemption date. If the
Calculation Agent exercises the option to liquidate the
Exchange Property, the Company will give notice to the
Trustee under the Indenture, as defined below, as to the
election to liquidate the Exchange Property which notice will
specify the method by which the Exchange Property will be
sold. The date of early redemption of the Callable STRIDES
will be the fifth Business Day following the last date on
which the Exchange Property is sold.

. consists of more than one type of property and the Calculation Agent
has not exercised its option to liquidate the Exchange Property,
then Holders of the Callable STRIDES will receive at the Stated
Maturity a pro rata share of each such type of Exchange Property;
and

. includes a cash component and the Calculation Agent has not
exercised its option to liquidate the Exchange Property, then
Holders of the Callable STRIDES will not receive any interest
accrued on such cash component.

In the event Exchange Property consists of securities, those securities will, in
turn, be subject to the antidilution adjustments set forth herein.

In the case of a consummated tender or exchange offer or going-private
transaction involving Exchange Property of a particular type, Exchange Property
shall be deemed to include the amount of cash or other property paid by the
offeror in the

10


tender or exchange offer with respect to such Exchange Property (in an amount
determined on the basis of the rate of exchange in such tender or exchange offer
or going-private transaction). In the event of a tender or exchange offer or a
going-private transaction with respect to Exchange Property in which an offeree
may elect to receive cash or other property, Exchange Property shall be deemed
to include the kind and amount of cash and other property received by offerees
who elect to receive cash.

If the Company elects to call the Callable STRIDES each Unit will
receive only any accrued and unpaid interest plus the Call Price, and will not
be entitled to receive Corning common stock, any Exchange Property or any other
consideration at the Stated Maturity.

The Calculation Agent shall be solely responsible for determination and
calculation of the Exchange Property if a Reorganization Event occurs and the
amount due upon early redemption, including the determination of the cash value
of any Exchange Property if necessary and its determinations and calculations
shall be conclusive absent manifest error.

The Calculation Agent may elect at its discretion to not make any of
the adjustments to the Share Multiplier or to the method of determining the
amount payable on each Unit of the Callable STRIDES described above, but may
instead make adjustments in its discretion to the Share Multiplier or the method
of determining the amount payable on each Unit of the Callable STRIDES that will
reflect the adjustments to the extent practicable made by the Options Clearing
Corporation on option contracts on Corning common stock or any successor common
stock. The Company will provide notice of any such election to the Trustee not
more than two Business Days following the date that the Options Clearing
Corporation publishes notice of its adjustments relating to Corning common stock
and will detail in such notice the actual adjustment made to the Share
Multiplier or to the method of determining the amount payable on each Unit of
the Callable STRIDES.

General

This Callable STRIDES is one of a duly authorized issue of Securities
of the Company, issued and to be issued under an Indenture, dated as of April 1,
1983, as amended and restated (herein referred to as the "Indenture"), between
the Company and JPMorgan Chase Bank, as Trustee (herein referred to as 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 statement of the respective rights thereunder of the Company, the Trustee
and the Holders of the Callable STRIDES, and the terms upon which the Callable
STRIDES are, and are to be, authenticated and delivered.

The Company hereby covenants for the benefit of the Holders of the
Callable STRIDES, to the extent permitted by applicable law, not to claim
voluntarily the benefits of any laws concerning usurious rates of interest
against a Holder of the Callable STRIDES.

11


As described above, the Callable STRIDES are subject to redemption by
the Company, but not at the option of the Holder, prior to the Stated Maturity.

In case an Event of Default with respect to any Callable STRIDES shall
have occurred and be continuing, the amount payable to a Holder of a Callable
STRIDES upon any acceleration permitted by the Callable STRIDES, with respect to
each Unit hereof, will be equal to the consideration due at the Stated Maturity
with respect to such Unit, calculated as though the date of acceleration were
the Stated Maturity of the Callable STRIDES, provided, however, that the value
of such consideration shall not be greater than an amount equal to the Call
Price plus any accrued and unpaid interest to but excluding the Call Date,
calculated as though the date of acceleration were the Call Date, whether or not
such date is before or after March 17, 2003.

If on any date the product of the Closing Market Price of Corning
common stock and the Share Multiplier is less than $2.00, the Callable STRIDES
will be redeemed on the third Business Day following such date and the Company
will deliver a number of shares of Corning common stock at the then current
Share Multiplier plus accrued and unpaid interest to such date.

In case of default in payment of the Callable STRIDES (whether at any
Interest Payment Date, the Stated Maturity, the Call Date or upon acceleration),
from and after that date the Callable STRIDES shall bear interest, payable upon
demand of the Holders thereof, at the rate of 2.2% per annum (to the extent that
payment of such interest shall be legally enforceable) on the unpaid amount due
and payable on such date in accordance with the terms of the Callable STRIDES to
the date payment of such amount has been made or duly provided for.

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 Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than 66 2/3% in aggregate public offering
price or principal amount, as the case may be, of the Securities at the time
Outstanding of each series affected thereby. Holders of specified percentages in
aggregate public offering price or principal amount of the Securities of each
series at the time Outstanding, on behalf of the Holders of all Securities of
each series, are permitted 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 Callable
STRIDES shall be conclusive and binding upon such Holder and upon all future
Holders of this Callable STRIDES and of any Callable STRIDES 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 Callable STRIDES.

No reference herein to the Indenture and no provision of this Callable
STRIDES or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay any consideration due with respect
to this Callable STRIDES and any interest on any overdue amount thereof at the
time, place, and rate, and in the coin or currency herein prescribed.

12


As provided in the Indenture and subject to certain limitations set
forth therein and on the first page hereof, the transfer of this Callable
STRIDES may be registered on the Security Register of the Company, upon
surrender of this Callable STRIDES for registration of transfer at the office or
agency of the Company in the Borough of Manhattan, The City of New York, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company duly executed by, the Holder hereof or by his
attorney duly authorized in writing, and thereupon one or more new Callable
STRIDES, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

The Callable STRIDES are issuable only in registered form without
coupons in denominations of $8.90 and integral multiples thereof. This Callable
STRIDES shall remain in the form of a global security held by a Depository.
Notwithstanding the foregoing, if (x) any Depository is at any time unwilling or
unable to continue as Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that this Callable STRIDES shall be exchangeable
or (z) an Event of Default has occurred and is continuing with respect to the
Callable STRIDES, this Callable STRIDES shall be exchangeable for Callable
STRIDES in definitive form of like tenor and of an equal aggregate principal
amount, in denominations of $8.90 and integral multiples thereof. Such
definitive Callable STRIDES shall be registered in such name or names as the
Depository shall instruct the Trustee. If definitive Callable STRIDES are so
delivered, the Company may make such changes to the form of this Callable
STRIDES as are necessary or appropriate to allow for the issuance of such
definitive Callable STRIDES.

No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or governmental charge payable in connection therewith.

The Company and each Holder of a Callable STRIDES by acceptance hereof
hereby agree (in the absence of an administrative determination or judicial
ruling to the contrary) to characterize a Callable STRIDES for all tax purposes
as an investment unit consisting of the following components: (i) a debt
instrument of the Company with a fixed principal amount unconditionally payable
on the maturity date equal to the principal amount of the Callable STRIDES and
bearing stated interest at the stated interest rate for the Callable STRIDES and
(ii) a forward contract pursuant to which the Holder agrees to use the principal
