MERRILL LYNCH & CO., INC.

Medium-Term Notes, Series C

Currency Basket Notes

(the “Notes”)

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

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, the Redemption Amount (as defined below) on the Stated Maturity.

Payment or delivery of the Redemption Amount and any interest on any overdue amount thereof with respect to this Global 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 Global Note is one of the series of Medium-Term Notes, Series C, Currency Basket Notes due on the Stated Maturity.

Payment at Maturity

The “Redemption Amount” with respect to the Notes shall be denominated in the Specified Currency and shall be determined by the Calculation Agent as described below:

(i) If the Ending Value (as defined below) is greater than the Starting Value, the Redemption Amount shall equal the Principal Amount multiplied by a percentage equal to:

(ii) If the Ending Value is equal to or less than the Starting Value, the Redemption Amount shall equal the Principal Amount multiplied by a percentage equal to the Starting Value.

2

The “Ending Value” shall equal the value of the Basket (as defined below) as determined by the Calculation Agent on the seventh scheduled Business Day (as defined below) before the Stated Maturity by adding 100 to the sum of the products of (1) the Multiplier of each Basket Component and (2) the then-current Exchange Rate (as defined below) for such Basket Component.

The “Basket” shall be a measure of the exchange rate movements of the Basket Components relative to the Base Currency.

The “Exchange Rates” shall be those rates reported by Bloomberg L.P.(“Bloomberg”) on page TKC7, and Reuters Group PLC on page SAEC or other applicable page at approximately the Valuation Time on the relevant date. If the currency exchange rates are not so quoted, then the Exchange Rates shall 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 shall 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 shall 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 only one bank, 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 shall 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.

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 manifest error, shall be conclusive for all purposes and binding on the Company and the Holders and beneficial owners of the Notes.

General

All percentages resulting from any calculation on the Notes shall be rounded to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards. For example, 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655). All dollar amounts used in or resulting from any calculation shall be rounded to the nearest cent with one-half cent being rounded upward.

Payment of principal and interest on the Notes shall be made at the office or agency of the Company maintained by the Company for such 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.
