MERRILL LYNCH & CO., INC.

Medium-Term Note, Series C

100% Principal Protected Conditional Participation Notes

(the “Notes”)

OTHER PROVISIONS: N/A

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) per Unit 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.

All determinations made by the Calculation Agent, absent a determination of manifest error, shall be conclusive for all purposes and binding on the Company and the holders and beneficial owners of this Global Note.

Payment on the Stated Maturity

On the Stated Maturity, a Holder shall receive a cash amount equal to, with respect to each Unit, the Redemption Amount per Unit.

The “Redemption Amount” per Unit shall be determined by the Calculation Agent and shall equal the $10.00 principal amount per Unit plus the Conditional Supplemental Payment, per Unit, if any.

(a)    If the Ending Value is greater than the Starting Value and equal to or less than the Threshold Level, the Conditional Supplemental Payment shall equal:

(b)    If the Ending Value is greater than the Threshold Level, the Conditional Supplemental Payment shall equal the Threshold Payment.

(c)    If the Ending Value is less than or equal to the Starting Value, the Conditional Supplemental Payment shall be zero.

In no case will the Conditional Supplemental Payment be less than zero.

The “Ending Value” shall be the closing level of the Index on the Valuation Date.

If a Market Disruption Event (as defined below) occurs or is continuing on the Valuation Date, then the closing level of the Index on the Valuation Date shall equal the closing level of the Index on the next scheduled Index Business Day prior to the Stated Maturity on which a Market Disruption Event has not occurred or is not continuing. If a Market Disruption Event occurs or is continuing on the second scheduled Index Business Day preceding the Stated Maturity, then the closing level of the Index will be determined by the Calculation Agent (or, if not determinable, estimated by the Calculation Agent) in a manner which is considered commercially reasonable under the circumstances.

Adjustments to the Index; Market Disruption Events

If at any time the Index Publisher makes a material change in the formula for or the method of calculating the Index or in any other way materially modifies the Index so that the

7

Index does not, in the opinion of the Calculation Agent, fairly represent the level of the Index had those changes or modifications not been made, then, from and after that time, the Calculation Agent shall, at the close of business in New York, New York, on each date that the closing level of the Index is to be calculated, make any adjustments as, in the good faith judgment of the Calculation Agent, may be necessary in order to arrive at a calculation of a level of a stock index comparable to the Index as if those changes or modifications had not been made, and calculate the closing level with reference to the Index, as so adjusted. Accordingly, if the method of calculating the Index is modified so that the level of the 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, then the Calculation Agent shall adjust the Index in order to arrive at a level of the Index as if it had not been modified, e.g., as if a split had not occurred. In the event the Calculation Agent makes any such adjustment to the Index, any determination as to the Ending Value of the Index shall be based on this closing level.

“Market Disruption Event” shall mean either of the following events as determined by the Calculation Agent in its sole discretion:

For the purpose of determining whether a Market Disruption Event has occurred:

8

Discontinuance of the Index

If the Index Publisher discontinues publication of the Index and the Index Publisher or another entity publishes a successor or substitute index that the Calculation Agent determines, in its sole discretion, to be comparable to the Index (a “Successor Index”), then, upon the Calculation Agent’s notification of that determination to the Trustee (as defined below) and the Company, the Calculation Agent shall substitute such Successor Index as calculated by the Index Publisher or any other entity for the Index. Upon any selection by the Calculation Agent of a Successor Index, the Company shall cause notice to be given to Holders of this Global Note.

In the event that the Index Publisher discontinues publication of the Index and:

the Calculation Agent shall compute a substitute level for the Index in accordance with the procedures last used to calculate the Index before any discontinuance or disallowance. If a Successor Index is selected or the Calculation Agent calculates a level as a substitute for the Index as described below, the Successor Index or level shall be used as a substitute for the Index for all purposes, including for the purpose of determining whether a Market Disruption Event exists. In such event, any determination as to the Ending Value shall be based on this closing level.

If the Index Publisher discontinues publication of the Index before the Valuation Date and the Calculation Agent determines that no Successor Index is available at that time, then on each Business Day until the earlier to occur of:

the Calculation Agent shall determine the level that would be used in determining the Redemption Amount as described in the preceding paragraph as if that day were the Valuation Date. In such event, any determination as to the Ending Value shall be based on this closing level. The Calculation Agent shall cause notice of each value 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 these values to be made available by telephone.

A “Business Day” is any day on which the NYSE, the AMEX and the Nasdaq (or any successor to the foregoing exchanges) are open for trading.

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

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.
