Global Currency Basket Notes

due August 2, 2004 (the “Notes”)

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, a sum for each Unit equal to the Redemption Amount, if any, as defined below, on August 2, 2004 (the “Stated Maturity”).

Payment or delivery of the Redemption Amount and any interest on any overdue amount thereof with respect to this Note 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 as at the time of payment is legal tender for payment of public and private debts.

This Note is one of the series of Global Currency Basket Notes due August 2, 2004.

Payment at Maturity

The “Redemption Amount” with respect to each Unit of this Note will be denominated in U.S. dollars and will be determined by the Calculation Agent, as defined below, as described below:

(i)  If the Ending Value (as defined below) is greater than the Starting Value (as defined below), the Redemption Amount per Unit will be the principal amount per Unit multiplied by a percentage equal to:

97 + (Participation Rate × (Ending Value–Starting Value))

(ii)  If the Ending Value is equal to or less than the Starting Value, the Redemption Amount will be the principal amount per Unit multiplied by 97%.

The “Starting Value” equals 100. The “Ending Value” will be determined by Merrill Lynch Capital Services, Inc. (the “Calculation Agent”) and will equal the value of the Global Currency Basket, as defined below, on the seventh scheduled Business Day prior to the Stated Maturity using the Exchange Rates (as defined below). The “Participation Rate” equals 300%.

The “Global Currency Basket”, or the “Basket”, is a measure of the exchange rate movements of the currencies set forth below, each a “Basket Component”, relative to the U.S. dollar. A fixed factor, the “Multiplier”, has been determined for each Basket Component by dividing the initial weighting of each Basket Component by its corresponding initial Exchange Rate, as defined below. The Multiplier for each Basket Component will remain fixed during the term of the Notes and can be used to calculate the value of the Global Currency Basket on any given day. To compute the value of the Global Currency Basket, (1) the Multiplier of each Basket Component is multiplied by the then-current Exchange Rate for such Basket Component, (2) the resulting products are summed and (3) the total is added to 100.

For each Basket Component, its initial weighting, initial Exchange Rate, Multiplier and initial index points based on such initial Exchange Rates are shown below.

2

The “Exchange Rates”, for purposes of determining the value of the Global Currency Basket, means those currency exchange rates in the interbank market quoted as one unit of the relevant currency in U.S. dollars as reported by Reuters Group PLC (“Reuters”) on page WRLD and WRLE, or any substitute page thereto, at approximately 10:00 a.m. New York City time on the relevant date. If the currency exchange rates are not so quoted on Reuters page WRLD and WRLE, or any substitute page thereto, then the Exchange Rates used to calculate the Basket will equal the noon buying rate in New York for cable transfers in foreign currencies as announced by the Federal Reserve Bank of New York for customs purposes (the “Noon Buying Rate”). If the Noon Buying Rate is not announced on such date, then the Exchange Rates will be calculated on the basis of the arithmetic mean of the applicable spot quotations received by the Calculation Agent at approximately 10:00 a.m. New York City time on the relevant date for the purchase or sale for deposits in the relevant currencies by the London offices of three leading banks engaged in the interbank market (selected in the sole discretion of the Calculation Agent) (the “Reference Banks”). If fewer than three Reference Banks provide such spot quotations, then the Exchange Rates will be calculated on the basis of the arithmetic mean of the applicable spot quotations received by the Calculation Agent at approximately 10:00 a.m. New York City time on the relevant date from two leading commercial banks in New York (selected in the sole discretion of the Calculation Agent), for the purchase or sale for deposits in the relevant currencies. If these spot quotations are available from fewer than two banks, then the Calculation Agent, in its sole discretion, shall determine which quotation is available and reasonable to be used. If no such spot quotation is available, then the Exchange Rates will be the rate the Calculation Agent, in its sole discretion, determines to be fair and reasonable under the circumstances at approximately 10:00 a.m. New York City time on the relevant date.”Reference Banks” means Citibank, N.A., Deutsche Bank A.G. and JPMorgan Chase Bank, or their successors.

A “Business Day” means any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions in The City of New York are authorized or required by law, regulation or executive order to close and such banks are open for dealing in a foreign exchange and foreign currency deposits.

All determinations made by the Calculation Agent shall be made in its sole discretion and, absent a determination of a manifest error, shall be conclusive for all purposes and binding on the Company and the Holders and beneficial owners of the Notes.

General

This Note 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 Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered.

The Company hereby covenants for the benefit of the Holders of the Notes, 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 Notes.

3

The Notes are not subject to redemption by the Company prior to the Stated Maturity.

In case an Event of Default with respect to any Notes shall have occurred and be continuing, the amount payable to a Holder of a Note upon any acceleration permitted by the Notes, with respect to each Unit, will be equal to the Redemption Amount, if any, calculated as though the date of early repayment were the Stated Maturity of the Notes.

In case of default in payment of the Notes (whether at the Stated Maturity or upon acceleration), from and after such date of default the Notes shall bear interest, payable upon demand of the Holders thereof, at the rate of 1.20% 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 Notes 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 original 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 original public offering price or principal amount, as the case may be, 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 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.

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, which is absolute and unconditional, to pay the Redemption Amount with respect to this Note and any interest on any overdue amount thereof at the time, place, and rate, and in the coin or currency herein prescribed.

As provided in the Indenture and subject to certain limitations set forth therein and on the first page hereof, the transfer of this Note may be registered on the Security Register of the Company, upon surrender of this Note 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 Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Notes are issuable only in registered form without coupons in denominations of a single Unit and integral multiples thereof. This Note 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

4

Company within 60 days, (y) the Company executes and delivers to the Trustee a Company Order to the effect that this Note shall be exchangeable or (z) an Event of Default has occurred and is continuing with respect to the Notes, this Note shall be exchangeable for Notes in definitive form of like tenor and of an equal aggregate principal amount, in denominations of a single Unit and integral multiples thereof. Such definitive Notes shall be registered in such name or names as the Depository shall instruct the Trustee. If definitive Notes are so delivered, the Company may make such changes to the form of this Note as are necessary or appropriate to allow for the issuance of such definitive Notes.

The Company shall treat the Notes as debt instruments for tax purposes, and, where required, shall file information returns with the Internal Revenue Service in accordance with this treatment, in the absence of any change or clarification in the law, by regulation or otherwise, requiring a different characterization of the Notes.

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.

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

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.

Unless the certificate of authentication hereon has been executed by JPMorgan Chase Bank, the Trustee under the Indenture, or its successor thereunder, by the manual signature of one of its authorized officers, this Note shall not be entitled to any benefits under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed under its corporate seal.

Dated: August 1, 2003
