MEDIUM-TERM NOTES, SERIES C

Leveraged Index Return Notes^®

(the “Notes”)

OTHER PROVISIONS:

1

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 payment per Unit equal to the Redemption Amount per Unit. The “Redemption Amount” with respect to each Unit shall be determined by the Calculation Agent and shall equal:

(i)     If the Ending Value (as defined below) is greater than the Starting Value:

provided, however, the Redemption Amount per Unit shall not exceed the Capped Value; or

(ii)    If the Ending Value is equal to or less than the Starting Value but is equal to or greater than the Threshold Value, the $10 original public offering price per Unit; or

(iii)    If the Ending Value is less than the Threshold Value:

The “Ending Value” shall equal the closing level of the Market Measure on the Calculation Day, provided that if a Market Disruption Event occurs on that date, the Ending Value shall be determined according to the Market Disruption Calculation (as described below).

Market Disruption Events

“Market Disruption Event” shall mean one or more of the following events as determined by the Calculation Agent:

2

In the event a Market Disruption Event has occurred on the Calculation Day, the Market Measure level shall be determined by the Calculation Agent pursuant to the following “Market Disruption Calculation”:

Adjustments to the Market Measure

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

3

Market Measure so that the Market Measure does not, in the opinion of the Calculation Agent, fairly represent the level of the Market Measure 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 Market Measure 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 commodity futures index comparable to such specific Market Measure as if those changes or modifications had not been made, and calculate the closing level with reference to the Market Measure, as so adjusted.

Discontinuance of the Market Measure

If the Market Measure Publisher discontinues publication of the Market Measure, and the Market Measure Publisher or another entity publishes a successor or substitute market measure that the Calculation Agent determines, in its sole discretion, to be comparable to the Market Measure (a “Successor Market Measure”), 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 Market Measure as calculated by the Market Measure Publisher or any other entity and calculate the Ending Value as described above under “Payment on the Stated Maturity”. Upon any selection by the Calculation Agent of a Successor Market Measure, the Company shall cause notice to be given to Holders of this Global Note.

In the event that the Market Measure Publisher discontinues publication of the Market Measure and:

the Calculation Agent shall compute a substitute level for the Market Measure in accordance with the procedures last used to calculate the Market Measure before any discontinuance. If a Successor Market Measure is selected or the Calculation Agent calculates a level as a substitute for the Market Measure as described below, the Successor Market Measure or level shall be used as a substitute for the Market Measure for all purposes, including the purpose of determining whether a Market Disruption Event exists.

If the Market Measure Publisher discontinues publication of the Market Measure before the Calculation Day and the Calculation Agent determines that no Successor Market Measure is available at that time, then on each Business Day (as defined below) until the earlier to occur of:

the Calculation Agent shall determine the value that would be used in computing the Redemption Amount per Unit as described in the preceding paragraph as if that day were a Calculation Day. The Calculation Agent shall cause notice of each value to be published not less often than once

4

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 (i) the Market Measure or any Successor Market Measure, if any, that has not been discontinued, is calculated and published and (ii) with respect to the Market Measure, or any Successor Market Measures, which have been discontinued, a day on which the applicable exchanges quoting the commodities futures contracts used to calculate a substitute level for the Market Measure following a discontinuance 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 9.87655% (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.
