Hypothetical Total Return Calculations

The following table illustrates the hypothetical simple total return (i.e., not compounded) on the Notes that could be realized on the applicable Review Date for a range of movements in the Index as shown under the column “Index Appreciation/Depreciation at Review Date.” The following table reflects a Call Level equal to the Initial Index Level of 1448.39 and that the percentages used to calculate the Call Premium applicable to the first, second and final Review Dates (as applicable) are 8.25%, 16.50%, 24.75%, respectively, regardless of the appreciation of the Index, which may be significant. There will be only one payment on the Notes whether called or at maturity. An entry of “N/A” indicates that the Notes would not be called on the applicable Review Date and no payment would be made for such date. The hypothetical returns set forth below are for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the Notes.

Examples

The following examples illustrate how the total returns set forth in the table above are calculated.

Example 1—The level of the Index increases from the Initial Index Level of 1448.39 to an Index closing level of 1520.81 on the first Review Date. Because the Index closing level on the first Review Date of 1520.81 is greater than the Call Level of 1448.39, the Notes are automatically called, and the investor receives a single payment of $1082.50 per $1,000 principal amount Note.

Example 2—The level of the Index decreases from the Initial Index Level of 1448.39 to an Index closing level of 1375.97 on the first Review Date, 1303.55 on the second Review Date and 1303.55 on the final Review Date. Because (a) the Index closing level on the first Review Date of 1375.97 is less than the corresponding Call Level of 1448.39 and the Index closing level on each of the other Review Dates (1303.55 and 1303.55) is less than the corresponding Call Level of 1448.39, and (b) the Ending Index Level has not declined by more than 10% from the Initial Index Level, the Notes are not called and the payment at maturity is the principal amount of $1,000 per $1,000 principal amount Note.

Example 3—The level of the Index decreases from the Initial Index Level of 1448.39 to an Index closing level of 1231.13 on the first Review Date, 1158.71 on the second Review Date and 1013.87 on the final Review Date. Because (a) the Index closing level on the first Review Date of 1231.13 is less than the corresponding Call Level of 1448.36 and the Index closing level on each of the other Review Dates (1158.71 and 1013.87) is less than the corresponding Call Level of 1448.39, and (b) the Ending Index Level is more than 10% below the Initial Index Level, the Notes are not called and the investor will receive a payment that is less than the principal amount calculated as follows for each $1,000 principal amount Note:

$1,000 + [$1,000 x (-30% + 10%) x 1.1111] = $777.78

TS-3

Selected Purchase Considerations

Appreciation Potential:  If the Index closing level is greater than or equal to the applicable Call Level on a Review Date, your investment will yield a payment per $1,000 principal amount of Note of $1,000 plus: (i) 8.25% x $1,000 if called on the first Review Date; (ii) 16.50% x $1,000 if called on the second Review Date (if applicable); (iii) 24.75% x $1,000 if called on the final Review Date (if applicable). Because the Notes are our senior unsecured obligations, payment of any amount if called or at maturity is subject to our ability to pay our obligations as they become due.

Potential Early Exit With Appreciation as a Result of Automatic Call Feature:  While the original term of the Notes is just over three years, the Notes will be called before maturity if the Index closing level is at or above the applicable Call Level on a Review Date and you will be entitled to the applicable payment set forth on the cover of this term sheet.

Limited Protection Against Loss:  If the Notes are not called and the Ending Index Level declines by no more than 10% as compared to the Initial Index Level, you will be entitled to receive the full principal amount of your Notes at maturity. If the Ending Index Level declines by more than 10%, for every 1% decline of the Index beyond 10% you will lose an amount equal to 1.1111% of the principal amount of your Notes.

Composition of the S&P 500 Index:  The S&P 500 Index is intended to provide an indication of the pattern of common stock price movement in the United States. The calculation of the level of the Index is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. As of January 31, 2007 the aggregate market value of the 500 companies included in the Index represented approximately 74% of the aggregate market value of stocks included in the Standard & Poor’s Stock Guide Database of domestic common stocks traded in the U.S., excluding American depositary receipts, limited partnerships and mutual funds. As of January 31, 2007 423 companies or 85.6% of the market capitalization of the Index traded on the New York Stock Exchange (“NYSE”); 77 companies or 14.4% of the market capitalization of the Index traded on The Nasdaq Stock Market (“Nasdaq”); and 0 companies or 0.0% of the market capitalization of the Index traded on the American Stock Exchange (“AMEX”). Ten main groups of companies comprise the Index, with the approximate percentage of the market capitalization of the Index included in each group as of January 31, 2007 indicated in parentheses: Consumer Discretionary (10.8%); Consumer Staples (9.3%); Energy (9.7%); Financials (22.2%); Health Care (12.2%); Industrials (10.8%); Information Technology (15.1%); Materials (3.1%); Telecommunication Services (3.6%); and Utilities (3.4%). See “The Index” in the accompanying product supplement no. RN-2.

Tax Treatment:  You should review carefully the section entitled “United States Federal Income Taxation” in the accompanying product supplement no. RN-2 and MTN prospectus supplement. The pricing of the Notes was subject to delivery of an opinion of our tax counsel, Sidley Austin LLP, that there exists a reasonable basis to characterize and treat the Notes as pre-paid cash-settled forward contracts linked to the level of the Index for U.S. federal income tax purposes. The opinion is subject to the limitations described in the section entitled “United States Federal Income Taxation” in product supplement no. RN-2 and is based on certain factual representations to be received from us on or prior to the date of this term sheet. Assuming this characterization and tax treatment is respected, absent a future clarification in current law (by an administrative determination, judicial ruling or otherwise), where required, ML&Co. intends to report your gain or loss on the Notes as long-term capital gain or loss if you hold the Notes for more than a year, whether or not you are an initial purchaser of Notes at the issue price. However, the Internal Revenue Service or a court may not respect this characterization and tax treatment of the Notes, in which case the timing and character of any income or loss on the Notes could be significantly and adversely affected. You should consult your tax adviser regarding the treatment of the Notes, including possible alternative characterizations and tax treatments.

Selected Risk Factors

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Index or any of the component stocks of the Index. These risks are explained in more detail in the “Risk Factors” sections of the accompanying product supplement no. RN-2 and MTN prospectus supplement.

Your investment may result in a loss

You will not receive interest on the Notes and we will not repay to you a fixed amount of principal on the Notes on the maturity date. The payment on the maturity date will depend on the change in the level of the Index. Because the level of the Index is subject to market fluctuations, the payment you receive on the maturity date may be more or less than the $1,000 principal amount per unit. If the Notes are not called, you will lose some or all of your investment on the maturity date if the Ending Index Level declines from the Initial Index Level by more than the buffer amount.

Your return is limited and the Notes are subject to an automatic early call

Your investment in the Notes will result in a gain if the Index closing level on any Review Date is greater than or equal to the Call Level on the applicable Review Date. This gain will be limited to the Call Premium applicable to the Review Date on which the Notes are called, regardless of the appreciation of the Index, which may be greater than the applicable Call Premium. In addition, the automatic call feature of the Notes may shorten the term of your investment.

TS-4

Your return, which could be negative, may be lower than the return on other debt securities of comparable maturity

The return that you will receive on your Notes, which could be negative, may be less than the return you could earn on other investments. Your return may be less than the return you would earn if you bought a traditional interest bearing debt security of ML&Co. with the same stated maturity date. Your investment may not reflect the full opportunity cost to you when you take into account factors that affect the time value of money. Unlike traditional interest bearing debt securities, the Notes do not guarantee the return of a principal amount on the maturity date.

A trading market for the Notes is not expected to develop and the terms of the Notes may affect the secondary market price of the Notes

The Notes will not be listed on any securities exchange, and we do not expect a trading market for the Notes to develop. The limited trading market for the Notes may adversely affect the price that an investor receives for their Notes if they do not wish to hold their investment until the maturity date.

In determining the economic terms of the Notes, and consequently the potential return on the Notes to you, a number of factors are taken into account. Among these factors are certain costs associated with creating, hedging and offering the Notes. In structuring the economic terms of the Notes, we seek to provide investors with what we believe to be commercially reasonable terms and to provide our affiliate MLPF&S with compensation for its services in developing the securities. The price, if any, at which you could sell your Notes in a secondary market transaction is expected to be adversely affected by the factors that we considered in setting the economic terms of the Notes, namely the underwriting discount paid in respect of the Notes and other costs associated with the Notes, and compensation for developing and hedging the product.

Your return will not reflect the return of a direct investment in the stocks included in the Index

You will not have voting rights or rights to receive cash dividends or other ownership rights in the stocks comprising the Index, and your return on the Notes will not reflect the return you would realize if you actually owned the stocks included in the Index and received the dividends paid on those stocks, if any, because the level of the Index is calculated by reference to the prices of the stocks included in the Index without taking into consideration the value of dividends paid on those stocks.

The trading value of the Notes will be affected by factors that interrelate in complex ways

The effect of one factor may offset the increase in the trading value of the Notes caused by another factor, and the effect of one factor may exacerbate the decrease in the trading value of the Notes caused by another factor. In addition to certain other factors described in the accompanying product supplement no. RN-2, these factors include, changes in (i) the level of the Index, (ii) interest rates, (iii) the volatility of the Index, (iv) dividend yields on the stocks included in the Index and (v) the credit rating of ML&Co.

Role of our subsidiary

MLPF&S, our subsidiary, is our agent for the purposes of calculating the Index closing level on any Review Date, the Ending Index Level and the payment on the maturity date. Under certain circumstances, MLPF&S as our subsidiary and due to its responsibilities as calculation agent for the Notes could give rise to conflicts of interest. MLPF&S is required to carry out its duties as calculation agent in good faith and using its reasonable judgment. However, because we control MLPF&S, potential conflicts of interest could arise. MLPF&S may also provide a hedge to us against the market risks associated with our obligations under the terms of the Note and MLPF&S or its affiliates may presently or from time to time engage in business with one or more of the companies included in the Index including extending loans to, or making equity investments in, those companies or providing advisory services to those companies, including merger and acquisition advisory services.

Tax consequences are uncertain

You should consider the tax consequences of investing in the Notes, aspects of which are uncertain. See the section entitled “United States Federal Income Taxation” in the accompanying product supplement no. RN-2.
