What are the Notes?

The Notes will be part of a series of senior debt securities issued by ML&Co. entitled “Medium-Term Notes, Series C” and will not be secured by collateral. The Notes will rank equally with all of our other unsecured and unsubordinated debt. The Notes will mature on November 6, 2009, unless redeemed by us as described in this pricing supplement.

Each unit will represent a single Note with a $10 original public offering price. You may transfer the Notes only in whole units. You will not have the right to receive physical certificates evidencing your ownership except under limited circumstances. Instead, we will issue the Notes in the form of a global certificate, which will be held by The Depository Trust Company, also known as DTC, or its nominee. Direct and indirect participants in DTC will record your ownership of the Notes. You should refer to the section entitled “Description of Debt Securities—Depositary” in the accompanying general prospectus supplement.

Are there any risks associated with my investment?

Yes, an investment in the Notes is subject to risks, including the risk of loss of principal. Please refer to the sections entitled “Risk Factors” in this pricing supplement and the accompanying MTN prospectus supplement.

What is the Composite Index?

The Composite Index is designed to provide exposure to a leveraged long position in the S&P 100 Index (the “Long Component”) equal to 150% of the initial level of the Composite Index, and a short position in the Russell 2000 Index (the “Short Component” and each Long Component or Short Component, an “Index Component”) equal to 50% of the initial level of the Composite Index. The Index Components are described in the sections entitled “The Composite Index—The Long Component” and “The Composite Index—The Short Component” in this pricing supplement. The Composite Index does not take into account any dividends paid on any of the stocks included in either Index Component (collectively, the “Component Stocks”).

Each Index Component was assigned a weighting that reflects the initial relative contribution of that Index Component to the level of the Composite Index. The positive weighting of 150% of the initial level of the Composite Index in the Long Component can be viewed as the equivalent of a leveraged long position in the Long Component. The negative weighting of 50% of the initial level of the Composite Index in the Short Component can be viewed as the equivalent of a short position in the Short Component. Changes in the level of the Index Component that has a greater absolute weighting will have a greater effect on the level of the Composite Index than changes in the level of the Index Component that has a lesser absolute weighting.

The level of the Composite Index was set to 100 on October 30, 2007, the date the Notes were priced for initial sale to the public (the “Pricing Date”).

A fixed factor (the “Multiplier”) was determined for each Index Component on the Pricing Date. The Multipliers can be used to calculate the level of the Composite Index on any given day by summing the products of the level of each Index Component and its designated Multiplier, as described in this pricing supplement. The Multipliers for each Index Component are listed in the section entitled “The Composite Index” in this pricing supplement.

An investment in the Notes does not entitle you to any dividends, voting rights or any other ownership interest in the Component Stocks.

How has the Composite Index performed historically?

The Composite Index did not exist until the Pricing Date. We have, however, included a table and a graph showing hypothetical historical month-end levels of the Composite Index from January 2002 through September 2007 based upon historical levels for each Index Component, the Multiplier for each Index Component calculated as of the Pricing Date and a Composite Index level of 100 on that date. In addition, we have included tables and graphs showing the historical month-end levels of each of the Index Components from January 2002 through September 2007. These tables are included in the section entitled “The Composite Index—The Long Component” and “The Composite—The Short Component” in this pricing supplement.

We have provided this information to help you evaluate the performance of the Composite Index in various economic environments; this information, however, is not necessarily indicative of how the Composite Index will perform in the future.

What will I receive on the maturity date of the Notes?

On the maturity date, if we have not previously redeemed the Notes, you will receive a cash payment per unit, denominated in U.S. dollars, equal to the Redemption Amount.

The “Redemption Amount” per unit to which you will be entitled will depend on the direction of and percentage change in the level of the Composite Index and will equal:

The “Starting Value” was set to 100 on the Pricing Date.

For purposes of determining the Redemption Amount, the “Ending Value” means the average of the levels of the Composite Index at the close of the market on five Index Business Days (as defined herein) shortly before the maturity date of the Notes. We may calculate the Ending Value by reference to fewer than five or even a single day’s closing level if, during the period shortly before the maturity date of the Notes, there is a disruption in trading of a sufficient number of the Component Stocks.

For more specific information about the Redemption Amount, please see the section entitled “Description of the Notes” in this pricing supplement.

Will I receive interest payments on the Notes?

You will not receive any interest payments on the Notes, but you will instead receive the Redemption Amount per unit on the maturity date based on the performance of the Composite Index from the Starting Value to the Ending Value. We have designed the Notes for investors who are willing to forego interest payments on the Notes, such as fixed or floating interest rates paid on traditional interest bearing debt securities, in exchange for receiving the Redemption Amount on the maturity date or on the Early Redemption Date (as defined below), if applicable.

How does the early redemption feature work?

If on any date prior to the seventh scheduled Index Business Day before the maturity date the closing level of the Composite Index is equal to or less than 50, we will redeem the Notes on the fifth Business Day following that date (the “Early Redemption Date”). If this redemption event is triggered, we will pay you the Redemption Amount, calculated as described above, in cash, on the Early Redemption Date; provided, however, for purposes of calculating the Redemption Amount to be paid on the Early Redemption Date, the Ending Value will be equal to the average of the closing levels of the Composite Index on the two scheduled Index Business Days immediately succeeding the date the closing level of the Composite Index is equal to or less than 50.

What about taxes?

The United States federal income tax consequences of an investment in the Notes are complex and uncertain. By purchasing a Note, you and ML&Co. agree, in the absence of an administrative determination, judicial ruling or other authoritative guidance to the contrary, to characterize and treat a Note for all tax purposes as a pre-paid cash-settled forward contract linked to the level of the Composite Index. Under this characterization and tax treatment of the Notes, you should be required to recognize gain or loss to the extent that you receive cash on the maturity date or upon a sale, exchange or early redemption of a Note prior to the maturity date. You should review the discussion under the section entitled “United States Federal Income Taxation” in this pricing supplement.

Will the Notes be listed on a securities exchange?

The Notes will not be listed on any securities exchange and we do not expect a trading market for the Notes to develop, which may affect the price you receive for your Notes upon any sale prior to the maturity date or redemption. You should review the section entitled “Risk Factors—A trading market for the Notes is not expected to develop and, if trading does develop, the market price you may receive or be quoted for your Notes on a date prior to the stated maturity date will be affected by this and other important factors including our costs of developing, hedging and distributing the Notes” in this pricing supplement.

What price can I expect to receive if I sell the Notes prior to the stated maturity?

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 MLPF&S with compensation for its services in developing the Notes.

If you sell your Notes prior to the stated maturity date, you will receive a price determined by market conditions for the Notes. This price may be influenced by many factors, such as interest rates, volatility and the current level of the Composite Index. In addition, the price, if any, at which you could sell your Notes in a secondary market transaction is expected to be 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. Depending on the impact of these factors, you may receive significantly less than the $10 original public offering price per unit of your Notes if sold before the stated maturity date.

In a situation where there had been no movement in the level of the Composite Index and no changes in the market conditions from those existing on the date of this pricing supplement, the price, if any, at which you could sell your Notes in a secondary market transaction is expected to be lower than the $10 original public offering price per unit. This is due to, among other things, our costs of developing, hedging and distributing the Notes. Any potential purchasers for your Notes in the secondary market are unlikely to consider these factors.

What is the role of MLPF&S?

MLPF&S, our subsidiary, is the underwriter for the offering and sale of the Notes. After the initial offering, MLPF&S intends to buy and sell Notes to create a secondary market for holders of the Notes, and may stabilize or maintain the market price of the Notes during their initial distribution. However, MLPF&S will not be obligated to engage in any of these market activities or continue them once it has started.

MLPF&S will also be our agent for purposes of determining, among other things, the Ending Value and calculating the Redemption Amount. Under certain circumstances, these duties could result in a conflict of interest between MLPF&S as our subsidiary and its responsibilities as calculation agent.

What is ML&Co.?

Merrill Lynch & Co., Inc. is a holding company with various subsidiaries and affiliated companies that provide investment, financing, insurance and related services on a global basis.

For information about ML&Co., see the section entitled “Merrill Lynch & Co., Inc.” in the accompanying general prospectus supplement. You should also read other documents ML&Co. has filed with the Securities and Exchange Commission, which you can find by referring to the sections entitled “Where You Can Find More Information” and “Incorporation of Information We File with the SEC” in the accompanying general prospectus supplement and prospectus.

RISK FACTORS

Your investment in the Notes will involve risks. You should carefully consider the following discussion of risks and the discussion of risks included in the accompanying MTN prospectus supplement before deciding whether an investment in the Notes is suitable for you.

Your investment may result in a loss

We will not repay you a fixed amount of principal on the Notes on the maturity date or on the Early Redemption Date. The Redemption Amount will depend on the direction of and percentage change in the level of the Composite Index. Because the level of the Composite Index is subject to market fluctuations, the Redemption Amount you receive may be more or less than the $10 original public offering price per unit. If the Ending Value is less than the Starting Value, the Redemption Amount will be less, and possibly significantly less, than the $10 original public offering price per unit.

In addition, if on any date prior to the seventh scheduled Index Business Day before the maturity date the closing level of the Composite Index is equal to or less than 50, the Notes will be redeemed early by us and you will receive, for each Note then owned by you, a cash amount, based on the percentage decrease in the level of the Composite Index calculated as described herein. This amount will be significantly less than the $10 original public offering price per unit.

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

The yield that you will receive on your Notes, which could be negative, may be less than the return you could earn on other investments. Your yield may be less than the yield 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.

You must rely on your own evaluation of the merits of an investment linked to the Composite Index

In the ordinary course of their businesses, affiliates of ML&Co. may express views on expected movements in the Long Component and Short Component; and these views are sometimes communicated to clients who participate in these indices. However, these views, depending upon economic, political and other developments, may vary over differing time-horizons and are subject to change. Moreover, other professionals who deal in U.S. equity markets may at any time have significantly different views from those of our affiliates. For these reasons, you are encouraged to derive information concerning the Index Components from multiple sources. In connection with your purchase of the Notes, you should not rely on views which may be expressed by our affiliates in the ordinary course of their businesses with respect to future movements in U.S. equity markets.

You should rely on your own evaluation of the merits of an investment in the Notes. Neither the offering of the Notes nor any views which may from time to time be expressed by our affiliates in the ordinary course of their businesses with respect to movements in the U.S. equity market constitutes a recommendation as to the merits of an investment in the Notes.

Your return will not reflect the return of owning the Component Stocks

The return on your Notes will not reflect the return you would realize if you actually owned the stocks represented by the leveraged long position in the Long Component and sold short the stocks represented by the short position in the Short Component. The Index Components will not reflect dividends paid on those stocks because the level of the Composite Index is calculated by reference to the prices of those stocks without taking into consideration the value of dividends, if any, paid on those stocks. The trading value of the Notes and final return on the Notes may also differ from the results of the Composite Index for the reasons discussed below under “—Many factors affect the trading value of the Notes; these factors interrelate in complex ways and the effect of any one factor may offset or magnify the effect of another factor”.

The long and short positions of the Index Components will have a substantial effect on the level of the Composite Index, and in turn, the value of the Notes

                The Composite Index will reflect a leveraged long position in the Long Component equal to 150% of the Starting Value of the Composite Index and a short position in the Short Component equal to 50% of the Starting Value of the Composite Index. The leveraged long position offers the potential for significant increases in the level of the Composite Index due to increases in the value of the Long Component, but also entails a high degree of risk, including the risk of magnified and substantial decreases in the level of the Composite Index if there are decreases in the value of the Long Component. In addition, as a result of the Short Component, any increase in the value of the Short Component will adversely affect the level of the Composite Index, and may offset any gains in the level of the Composite Index related to increases in the value of the Long Component. Because of the leveraged weighting of the Long Component, changes in its absolute value will have a greater effect on the level of the Composite Index than similar changes in the value of the Short Component. We cannot assure you of the direction of or percentage change in either Index Component from the Starting Value to the Ending Value.

In seeking to provide investors with what we believe to be commercially reasonable terms for the Notes while providing MLPF&S with compensation for its services, we have considered the costs of developing, hedging and distributing the Notes. If a trading market develops for the Notes (and such a market may not develop), these costs are expected to affect the market price you may receive or be quoted for your Notes on a date prior to the stated maturity date

The Notes will not be listed on any futures or securities exchange and we do not expect a trading market for the Notes to develop. Although MLPF&S, our subsidiary, has indicated that it currently expects to bid for Notes offered for sale to it by holders of the Notes, it is not required to do so and may cease making those bids at any time. In addition, while we describe in this pricing supplement how you can calculate the level of the Composite Index from publicly available information, we will not publish the level of the Composite Index over the term of the Notes and this may limit the trading market for the Notes. The development of a trading market for the Notes will depend on our financial performance and other factors, including changes in the level of the Composite Index. If the trading market for the Notes is limited, there may be a limited number of buyers for your Notes if you do not wish to hold your investment until that stated maturity date. This may affect the price you receive.

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 MLPF&S with compensation for its services in developing the securities. If MLPF&S makes a market in the Notes, the price it quotes would reflect any changes in market conditions and other relevant factors. In addition, the price, if any, at which you could sell your Notes in a secondary market transaction is expected to be 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. This quoted price could be higher or lower than the $10 original public offering price. Furthermore, there is no assurance that MLPF&S or any other party will be willing to buy the Notes. MLPF&S is not obligated to make a market in the Notes.

Assuming there is no change in the level of the Composite Index and no change in market conditions or any other relevant factors, the price, if any, at which MLPF&S or another purchaser might be willing to purchase your Notes in a secondary market transaction is expected to be lower than the $10 original public offering price. This is due to, among other things, the fact that the $10 original public offering price included, and secondary market prices are likely to exclude, underwriting discount paid with respect to, and the developing and hedging costs associated with, the Notes.

The respective publishers of the Index Components may adjust the Index Components in a way that affects their levels, and these respective publishers have no obligation to consider your interests

Standard & Poor’s, a division of The McGraw-Hill Companies, Inc. (“Standard & Poor’s” or “S&P”), and Frank Russell Company (“FRC”) (together the “Index Publishers” and each an “Index Publisher”) are the publishers of the S&P 100 Index and the Russell 2000 Index, respectively. The Index Publishers can add, delete or substitute the stocks underlying the Index Components or make other methodological changes that could change the level of the Composite Index. You should realize that the changing of companies included in the Index Components may affect the Composite Index, as a newly added company may perform significantly better or worse than the company or companies it replaces. Additionally, an Index Publisher may alter, discontinue or suspend calculation or dissemination of its respective Index Component. Any of these actions could adversely affect the value of the Notes. The Index Publishers have no obligation to consider your interests in calculating or revising the Index Components. See “The Composite Index.”

Many factors affect the trading value of the Notes; these factors interrelate in complex ways and the effect of any one factor may offset or magnify the effect of another factor

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. For example, a change in interest rates may offset some or all of any increase in the trading value of the Notes attributable to another factor, such as an increase in the level of the Composite Index. The following paragraphs describe the expected impact on the trading value of the Notes given a change in a specific factor, assuming all other conditions remain constant.

The level of the Composite Index is expected to affect the trading value of the Notes. We expect that the trading value of the Notes will depend substantially on the amount, if any, by which the level of the Composite Index exceeds or does not exceed the Starting Value. However, if you choose to sell your Notes when the level of the Composite Index exceeds the Starting Value, you may receive substantially less than the amount that would be payable on the maturity date based on this level because of the expectation that the level of the Composite Index will continue to fluctuate until the Ending Value is determined.

Table of Contents

Changes in the volatility of the Index Components are expected to affect the trading value of the Notes. Volatility is the term used to describe the size and frequency of price and/or market fluctuations. If the volatility of the Index Components increases or decreases, the trading value of the Notes may be adversely affected.

Changes in the levels of interest rates are expected to affect the trading value of the Notes. We expect that changes in interest rates will affect the trading value of the Notes. Generally, if United States interest rates increase, we expect the trading value of the Notes will decrease and, conversely, if United States interest rates decrease, we expect the trading value of the Notes will increase.

Changes in dividend yields of the Component Stocks are expected to affect the trading value of the Notes. In general, if dividend yields on the Component Stocks in which there is a long position increase, we expect that the trading value of the Notes will decrease and, conversely, if dividend yields on those stocks decrease, we expect that the trading value of the Notes will increase. In general, if dividend yields on the Component Stocks in which there is a short position decrease, we expect that the trading value of the Notes will decrease and, conversely, if dividend yields on those stocks increase, we expect that the trading value of the Notes will increase.

Changes in our credit ratings may affect the trading value of the Notes. Our credit ratings are an assessment of our ability to pay our obligations. Consequently, real or anticipated changes in our credit ratings may affect the trading value of the Notes. However, because the return on your Notes is dependent upon factors in addition to our ability to pay our obligations under the Notes, such as the percentage increase, if any, in the level of the Composite Index over the term of the Notes, an improvement in our credit ratings will not reduce the other investment risks related to the Notes.

In general, assuming all relevant factors are held constant, we expect that the effect on the trading value of the Notes of a given change in some of the factors listed above will be less if it occurs later in the term of the Notes than if it occurs earlier in the term of the Notes. We expect, however, that the effect on the trading value of the Notes of a given change in the level of the Composite Index will be greater if it occurs later in the term of the Notes than if it occurs earlier in the term of the Notes.

Amounts payable on the Notes may be limited by state law

New York State law governs the 1983 Indenture under which the Notes will be issued. New York has usury laws that limit the amount of interest that can be charged and paid on loans, which includes debt securities like the Notes. Under present New York law, the maximum rate of interest is 25% per annum on a simple interest basis. This limit may not apply to debt securities in which $2,500,000 or more has been invested.

While we believe that New York law would be given effect by a state or federal court sitting outside of New York, many other states also have laws that regulate the amount of interest that may be charged to and paid by a borrower. We will promise, for the benefit of the holders of the Notes, to the extent permitted by law, not to voluntarily claim the benefits of any laws concerning usurious rates of interest.

Purchases and sales by us and our affiliates may affect your return

We and our affiliates may from time to time buy or sell the Component Stocks or futures or options contracts on those stocks for our own accounts for business reasons and expect to enter into these transactions in connection with hedging our obligations under the Notes. These transactions could affect the price of those stocks and, in turn, the level of the Composite Index, in a manner that would be adverse to your investment in the Notes. Any purchases or sales by us, our affiliates or others on our behalf on or before the Pricing Date may temporarily increase or decrease the prices of the Component Stocks. Temporary increases or decreases in the market prices of the Component Stocks may also occur as a result of the purchasing activities of other market participants. Consequently, the prices of the Component Stocks may change subsequent to the Pricing Date, affecting the level of the Composite Index and therefore the trading value of the Notes.

Potential conflicts

MLPF&S, our subsidiary, is our agent for the purposes of calculating, among other things, the Ending Value and Redemption Amount. Under certain circumstances, MLPF&S as our subsidiary and in its responsibilities as calculation agent for the Notes could give rise to conflicts of interest. These conflicts could occur, for instance, in connection with its determination as to whether the level of the Composite Index can be calculated on a particular trading day, or in connection with judgments that it would be required to make in the event of a discontinuance or unavailability of an Index Component. See the sections entitled “Description of the Notes—Payment on the Maturity Date,” “Description of the Notes—Adjustments to the Index Components” and “Description of the Notes—Discontinuance of the Index Components” in this pricing supplement. 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.

                We expect to enter into arrangements to hedge the market risks associated with our obligation to pay the Redemption Amount due on the maturity date or the Early Redemption Date, as applicable, on the Notes. We may seek competitive terms in

entering into the hedging arrangements for the Notes, but are not required to do so, and we may enter into such hedging arrangements with one of our subsidiaries or affiliated companies. Such hedging activity is expected to result in a profit to those engaging in the hedging activity, which could be more or less than initially expected, but which could also result in a loss for the hedging counterparty.

ML&Co. or its affiliates may presently or from time to time engage in business with one or more of the companies included in the Composite 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. In the course of business, ML&Co. or its affiliates may acquire non-public information relating to those companies and, in addition, one or more affiliates of ML&Co. may publish research reports about those companies. ML&Co. does not make any representation to any purchasers of the Notes regarding any matters whatsoever relating to the companies included in the Composite Index. Any prospective purchaser of the Notes should undertake an independent investigation of the companies included in the Composite Index as in its judgment is appropriate to make an informed decision regarding an investment in the Notes. The composition of those companies does not reflect any investment recommendations of ML&Co. or its affiliates.

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 this pricing supplement.

DESCRIPTION OF THE NOTES

ML&Co. will issue the Notes as part of a series of senior unsecured debt securities entitled “Medium-Term Notes, Series C,” which is more fully described in the MTN prospectus supplement, under the 1983 Indenture, which is more fully described in the accompanying general prospectus supplement. The Bank of New York has succeeded JPMorgan Chase Bank, N.A. as trustee under such indenture. Unless earlier redeemed by us as provided below, the Notes will mature on November 6, 2009. Information included in this pricing supplement supersedes information in the accompanying MTN prospectus supplement, general prospectus supplement and prospectus to the extent that it is different from that information. The CUSIP number for the Notes is 59022W257.

The Notes may be redeemed by ML&Co. as described in this pricing supplement. The Notes are not subject to redemption at the option of any holder prior to the stated maturity date.

ML&Co. will issue the Notes in denominations of whole units each with a $10 original public offering price per unit. You may transfer the Notes only in whole units. You will not have the right to receive physical certificates evidencing your ownership except under limited circumstances. Instead, we will issue the Notes in the form of a global certificate, which will be held by The Depository Trust Company, also known as DTC, or its nominee. Direct and indirect participants in DTC will record your ownership of the Notes. You should refer to the section entitled “Description of Debt Securities—Depositary” in the accompanying general prospectus supplement.

The Notes will not have the benefit of any sinking fund and there is no principal protection on the Notes.

Payment on the Maturity Date

On the maturity date, unless the Notes have been previously redeemed by us as provided below under “—Redemption Event”, a holder of a Note will be entitled to receive the Redemption Amount per unit payable on that Note, as provided below. There will be no payment of interest, periodic or otherwise, on the Notes.

Determination of the Redemption Amount

The “Redemption Amount” per unit, denominated in U.S. dollars, will be determined by the calculation agent and will equal:

The “Starting Value” was set to 100 on the Pricing Date.

For purposes of determining the Redemption Amount payable on the maturity date, the “Ending Value” will be determined by the calculation agent and will equal the average of the closing levels of the Composite Index determined on each of the first five Calculation Days during the Calculation Period. If there are fewer than five Calculation Days during the Calculation Period, then the Ending Value will equal the average of the closing levels of the Composite Index on those Calculation Days. If there is only one Calculation Day during the Calculation Period, then the Ending Value will equal the closing level of the Composite Index on that Calculation Day. If no Calculation Days occur during the Calculation Period, then the Ending Value will equal the closing level of the Composite Index determined (or, if not determinable, estimated by the calculation agent in a manner which it considers commercially reasonable under the circumstances) on the last scheduled Index Business Day in the Calculation Period, regardless of the occurrence of a Market Disruption Event (as described below) on that scheduled Index Business Day.

The “Calculation Period” means the period from and including the seventh scheduled Index Business Day before the maturity date to and including the second scheduled Index Business Day before the maturity date.

A “Calculation Day” means any Index Business Day during the Calculation Period on which a Market Disruption Event has not occurred.

PS-11

Table of Contents

An “Index Business Day” means a day on which the New York Stock Exchange (the “NYSE”), the American Stock Exchange (the “AMEX”) and The Nasdaq Stock Market (“Nasdaq”) are open for trading and the Index Components or any successor indices are calculated and published.

“Market Disruption Event” means either of the following events as determined by the calculation agent:

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

The occurrence of a Market Disruption Event could affect the calculation of the Redemption Amount on the maturity date or Early Redemption Date. See “—Payment on the Maturity Date” and “—Redemption Event” in this pricing supplement.

All determinations made by the calculation agent, absent a determination of manifest error, will be conclusive for all purposes and binding on ML&Co. and the holders and beneficial owners of the Notes.

Hypothetical Returns

The following table illustrates, for the Starting Value of 100 and a range of hypothetical Ending Values:

This table assumes that the closing level of the Composite Index is not equal to or less than 50 on any date before the seventh scheduled Index Business Day before the maturity date. Therefore, the Notes were not subject to early redemption.

The above figures are for purposes of illustration only. The actual amount received by you and the resulting total and pretax annualized rates of return will depend on the actual Ending Value and the term of your investment.

Redemption Event

If on any date before the first scheduled Calculation Day of the Calculation Period the closing level of the Composite Index is equal to or less than 50, we will redeem all and not less than all of the Notes on the fifth Business Day following that date (the “Early Redemption Date”). If this redemption event is triggered, we will pay you the Redemption Amount, as described above under “—Payment on the Maturity Date,” in cash, on the Early Redemption Date; provided, however, for purposes of calculating the Redemption Amount to be paid on an Early Redemption Date, the Ending Value will be equal to the average of the closing levels of the Composite Index on the two scheduled Index Business Days immediately succeeding the date the closing level of the Composite Index was equal to or less than 50; provided that if a Market Disruption Event occurs on the first such date and as a result there is only one Calculation Day, the Ending Value will be determined on that second Calculation Day, and if a Market Disruption Event occurs on both dates, the Ending Value will be determined using the closing level of the Composite Index (or, if not determinable, estimated by the calculation agent in a manner which it considers commercially reasonable under the circumstances) on the second scheduled Index Business Day following the date the closing level of the Composite Index was equal to or less than 50, regardless of the occurrence of a Market Disruption Event on that scheduled Index Business Day.

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.

Adjustments to the Index Components

If at any time an Index Publisher makes a material change in the formula for or the method of calculating its respective Index Component or in any other way materially modifies that Index Component so that the Index Component does not, in the opinion of the calculation agent, fairly represent the level of that Index Component had those changes or modifications not been made, then, from and after that time, the calculation agent will, at the close of business in New York, New York, on each date that the closing value of the Composite 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 that Index Component as if those changes or modifications had not been made, and calculate the closing level with reference to the Index Component, as so adjusted. Accordingly, if the method of calculating an Index Component is modified so that the level of the Index Component is a fraction or a multiple of what it would have been if it had not been modified, then the calculation agent will adjust such Index Component in order to arrive at a level of the Index Component as if it had not been modified.

Discontinuance of the Index Components

If an Index Publisher discontinues publication of its respective Index Component 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 that Index Component (a “successor index”), then, upon the calculation agent’s notification of that determination to the trustee and ML&Co., the calculation agent will substitute the successor index as calculated by the relevant Index Publisher or any other entity for the Index Component and calculate the Ending Value as described above under “—Payment on the Maturity Date” or “—Redemption Event”, as applicable. Upon any selection by the calculation agent of a successor index, ML&Co. will cause notice to be given to holders of the Notes.

In the event that an Index Publisher discontinues publication of its respective Index Component and:

the calculation agent will compute a substitute level for that Index Component in accordance with the procedures last used to calculate that Index Component before any discontinuance. If a successor index is selected or the calculation agent calculates a level as a substitute for the Index Component as described below, the successor index or level will be used as a substitute for that Index Component for all purposes, including for purposes of determining whether a Market Disruption Event exists.

If an Index Publisher discontinues publication of its respective Index Component before the Calculation Period 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:

PS-14

Table of Contents

the calculation agent will determine the value that would be used in computing the Redemption Amount as described in the preceding paragraph as if that day were a Calculation Day. The calculation agent will 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.

Notwithstanding these alternative arrangements, discontinuance of the publication of an Index Component may adversely affect trading in the Notes.

Events of Default and Acceleration

In case an Event of Default with respect to any Notes has occurred and is continuing, the amount payable to a holder of a Note upon any acceleration permitted by the Notes, with respect to each $10 original public offering price per unit, will be equal to the Redemption Amount per unit, calculated as though the date of acceleration were the stated maturity date of the Notes.

In case of default in payment of the Notes, whether on the stated maturity date, the Early Redemption Date, or upon acceleration, from and after that date the Notes will bear interest, payable upon demand of their holders, at the then current Federal Funds Rate, reset daily, as determined by reference to Reuters page FEDFUNDS1 under the heading “EFFECT”, to the extent that payment of such interest shall be legally enforceable, on the unpaid amount due and payable on that date in accordance with the terms of the Notes to the date payment of that amount has been made or duly provided for. “Reuters page FEDFUNDS1” means such page or any successor page, or page on a successor service, displaying such rate. If the Federal Funds Rate cannot be determined by reference to Reuters page FEDFUNDS1, such rate will be determined in accordance with the procedures set forth in the accompanying MTN prospectus supplement relating to the determination of the Federal Funds Rate in the event of the unavailability of Moneyline Telerate page 120.

THE COMPOSITE INDEX

Composite Index

The Composite Index is designed to allow investors to participate in the percentage change in the value of a leveraged long position in the S&P 100 Index (the “Long Component”) and a short position in the Russell 2000 Index (the “Short Component”), the two indices comprising the Composite Index (each, an “Index Component”), from the Starting Value to the Ending Value. Each of the Index Components is described in the sections entitled “—The Long Component” and “—The Short Component” below. Each Index Component was assigned an initial weighting and that reflects the initial relative contribution of that Index Component to the level of the Composite Index. The positive weighting of 150% of the initial level of the Composite Index in the Long Component can be viewed as a leveraged long position in the Long Component. The negative weighting of 50% of the initial level of the Composite Index in the Short Component can be viewed as a short position in the Short Component.

Determination of the Multiplier for each Index Component

A fixed factor (the “Multiplier”) was determined for each Index Component on the Pricing Date based upon the initial weighting of each Index Component and equals:

The Multipliers were calculated in this way so that the level of the Composite Index would equal 100 on the Pricing Date. The Multipliers will remain fixed over the term of the Notes, except that the calculation agent may in its good faith judgment adjust the Multiplier of any Index Component in the event that Index Component is changed or modified in a manner that does not, in the opinion of the calculation agent, fairly represent the level of that Index Component had those changes or modifications not been made.

The Multipliers for each Index Component as of the Pricing Date are listed under “—Computation of the Composite Index” below.

Computation of the Composite Index

The calculation agent will calculate the closing level of the Composite Index by summing the products of the closing level for each Index Component on a Calculation Day and the Multiplier applicable to each Index Component. The level of the Composite Index will vary based on the appreciation or depreciation of each Index Component and on whether there is a long or short position in that Index Component. Any appreciation in the value of the Long Component will result in an increase in the level of the Composite Index because of the long position. Conversely, any depreciation in the value of the Long Component will result in a decrease in the level of the Composite Index because of the long position. Any depreciation in the value of the Short Component will result in an increase in the level of the Composite Index because of the short position. Conversely, any appreciation in the value of the Short Component will result in a decrease in the level of the Composite Index because of the short position. Because of the leveraged weighting of the Long Component, changes in its absolute value will have a greater effect on the level of the Composite Index than similar changes in the value of the Short Component. We cannot assure you of the direction of or percentage change in either Index Component from the Starting Value to the Ending Value. On the Pricing Date, for each Index Component, the weighting, closing level, Multiplier and initial Composite Index contribution were as follows:

The Long Component

The Long Component is the S&P 100 Index. All disclosure contained in this pricing supplement regarding the S&P 100 Index, including, without limitation, its make-up, method of calculation and changes in its components has been derived from publicly available information prepared by Standard & Poor’s. ML&Co. and MLPF&S have not independently verified the accuracy or completeness of that information.

Description of the S&P 100 Index

Standard & Poor’s, a division of The McGraw-Hill Companies, Inc. (“Standard & Poor’s” or “S&P”) publishes the S&P 100 Index. The S&P 100 Index, a subset of the S&P 500 Index, is comprised of 100 leading U.S. stocks with exchange-listed options. Constituents of the S&P 100 Index are selected for sector balance and represent about 57% of the market capitalization of the S&P 500 Index and almost 45% of the market capitalization of the U.S. equity markets. The stocks in the S&P 100 Index are generally among the largest and most established companies in the S&P 500 Index. In past years, turnover among stocks in the S&P 100 Index has been even lower than the turnover in the S&P 500 Index. Index options on the S&P 100 Index are traded with the ticker symbol OEX. Because of the popularity of these options, investors often refer to the S&P 100 Index by its ticker. The S&P 100 Index was originally developed by the Chicago Board Options Exchange (CBOE), which later transferred the S&P 100 Index to Standard & Poor’s for management. The Standard & Poor’s U.S. Index Committee, which oversees the S&P 500 Index and other Standard & Poor’s U.S. equity indices, also maintains the S&P 100 Index.

Index Methodology

Because the S&P 100 Index is derived from the S&P 500 Index, the S&P 100 Index stocks are subject to the published S&P 500 Index criteria for additions and deletions. The guidelines the Index Committee employs provide the transparency required for investors to use the S&P 100 Index to fulfill their particular investing needs.

The Index Committee may remove a company from the S&P 100 Index if the company does not meet the inclusion qualifications or if the S&P 100 Index becomes unbalanced in its sector representation. The Index Committee may also remove any company that violates any of the S&P 500 Index criteria.

S&P 500 Index

All disclosure contained in this pricing supplement regarding the S&P 500 Index, including, without limitation, its make-up, method of calculation and changes in its components has been derived from publicly available information prepared by Standard & Poor’s. ML&Co. and MLPF&S have not independently verified the accuracy or completeness of that information.

The S&P 500 Index is published by Standard & Poor’s and 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 S&P 500 Index, discussed below in

PS-18

Table of Contents

further detail, 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. Relevant criteria employed by Standard & Poor’s include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the market price of that company’s common stock is generally responsive to changes in the affairs of the respective industry and the market value and trading activity of the common stock of that company. Ten main groups of companies comprise the S&P 500 Index: Consumer Discretionary; Consumer Staples; Energy; Financials; Health Care; Industrials; Information Technology; Materials; Telecommunication Services; and Utilities. Standard & Poor’s may from time to time, in its sole discretion, add companies to, or delete companies from, the S&P 500 Index to achieve the objectives stated above.

The S&P 500 Index does not reflect the payment of dividends on the stocks included in the S&P 500 Index. Because of this, the calculation of the Ending Value will not reflect the payment of dividends on these stocks that investors would receive if they were to purchase these stocks and hold them for a period equal to the term of the Notes.

Computation of the S&P 500 Index

While S&P currently employs the following methodology to calculate the S&P 500 Index, no assurance can be given that S&P will not modify or change this methodology in a manner that may affect the Redemption Amount.

Historically, the market value of any underlying stocks included in the S&P 500 Index was calculated as the product of the market price per share and the number of the then outstanding shares of that underlying stock. In March 2005, S&P began shifting the S&P 500 Index half way from a market capitalization weighted formula to a float-adjusted formula, before moving the S&P 500 Index to full float adjustment on September 16, 2005. S&P’s criteria for selecting stocks for the S&P 500 Index did not change by the shift to float adjustment. However, the adjustment affects each company’s weight in the S&P 500 Index (i.e., its market value).

Under float adjustment, the share counts used in calculating the S&P 500 Index reflect only those shares that are available to investors, not all of a company’s outstanding shares. Standard and Poor’s defines three groups of shareholders whose holdings are subject to float adjustment:

However, treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. In cases where holdings in a group exceed 10% of the outstanding shares of a company, the holdings of that group are excluded from the float-adjusted count of shares to be used in the S&P 500 Index calculation. Shares held by mutual funds, investment advisory firms, pension funds, or foundations not associated with the company and investment funds in insurance companies, shares of a United States company traded in Canada as “exchangeable shares,” shares that trust beneficiaries may buy or sell without difficulty or significant additional expense beyond typical brokerage fees, and, if a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class if such shares are convertible by shareholders without undue delay and cost, are also part of the float.

For each stock, an investable weight factor (“IWF”) is calculated by dividing (x) the available float shares, defined as the total shares outstanding less shares held in one or more of the three groups listed above where the group holdings exceed 10% of the outstanding shares, by (y) the total shares outstanding. The float-adjusted index is then calculated by dividing (w) the sum of the IWF multiplied by both the price and the total shares outstanding for each stock by (z) the index divisor. For companies with multiple classes of stock, Standard & Poor’s calculates the weighted average IWF for each stock using the proportion of the total company market capitalization of each share class as weights.

The S&P 500 Index is calculated using a base-weighted aggregate methodology: the level of the S&P 500 Index reflects the total market value of all 500 component stocks relative to the base period of the years 1941 through 1943 (the

PS-19

Table of Contents

“base period”). An indexed number is used to represent the results of this calculation in order to make the value easier to work with and track over time. The actual total market value of the component stocks during the base period of the years 1941 through 1943 has been set to an indexed value of 10. This is often indicated by the notation 1941-43 = 10. In practice, the daily calculation of the S&P 500 Index is computed by dividing the total market value of the component stocks by the “index divisor.” By itself, the index divisor is an arbitrary number. However, in the context of the calculation of the S&P 500 Index, it serves as a link to the original base period level of the S&P 500 Index. The index divisor keeps the S&P 500 Index comparable over time and is the manipulation point for all adjustments to the S&P 500 Index.

S&P 500 Index Maintenance

S&P 500 Index maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to company restructuring or spinoffs.

To prevent the level of the S&P 500 Index from changing due to these corporate actions, all corporate actions which affect the level of the S&P 500 Index require an index divisor adjustment. By adjusting the index divisor for the change in total market value of an individual company, the level of the S&P 500 Index remains constant. This helps maintain the level of the S&P 500 Index as an accurate barometer of stock market performance and ensures that the movement of the S&P 500 Index is not caused by the corporate action an individual company. All index divisor adjustments are made after the close of trading and after the calculation of the S&P 500 Index closing level.

Some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the S&P 500 Index and do not require index divisor adjustments.

Changes in a company’s shares outstanding of 5.0% or more due to mergers, acquisitions, public offerings, private placements, tender offers, Dutch auctions, or exchange offers are made as soon as reasonably possible. All other changes of 5.0% or more (due to, for example, company stock repurchases, redemptions, exercise of options, warrants, subscription rights, conversion of preferred stock, notes, debt, equity participation units, or other recapitalizations) are made weekly and are announced on Tuesday for implementation after the close of trading on Wednesday. Changes of less than 5.0% are accumulated and made quarterly on the third Friday of March, June, September, and December, and are usually announced two days prior.

Also, changes in IWFs of more than ten percentage points caused by corporate actions (such as merger and acquisition activity, restructurings, or spinoffs) will be made as soon as reasonably possible. Other changes in IWFs will be made annually, in September when IWFs are reviewed.

The Short Component

The Short Component is the Russell 2000 Index. All disclosure contained in this pricing supplement regarding the Russell 2000 Index, including, without limitation, its make-up, method of calculation and changes in its components has been derived from publicly available sources. The information reflects the policies of Frank Russell Company (“FRC”) as stated in these sources and these policies are subject to change at the discretion of FRC. ML&Co. and MLPF&S have not independently verified and make no representation as to the accuracy or completeness of such information.

Description of the Russell 2000 Index

FRC began dissemination of the Russell 2000 Index on January 1, 1987 and calculates and publishes the Russell 2000 Index on Bloomberg L.P. (“Bloomberg”) under index symbol “RTY”. The Russell 2000 Index was set to 135 as of the close of business on December 31, 1986. The Russell 2000 Index measures the composite price performance of stocks of 2,000 companies which are either domiciled in the United States, its territories or are eligible for inclusion as a BDI (as defined below). All 2,000 stocks are traded on a major U.S. exchange and form a part of the Russell 3000 Index. The Russell 3000 Index is composed of the 3,000 largest companies either domicilied in the United States or its territories, or companies eligible for inclusion as a BDI, as determined by market capitalization and represents approximately 98% of the United States equity market.

The Russell 2000 Index consists of the smallest 2,000 companies included in the Russell 3000 Index and represents approximately 8% of the total market capitalization of the Russell 3000 Index. The Russell 2000 Index is designed to track the performance of the small capitalization segment of the United States equity market. The Russell 2000 Index is determined, comprised and calculated by FRC without regard to the Notes.

Selection of Stocks Underlying the Russell 2000 Index

Companies domiciled in the United States and its territories are eligible for inclusion in the Russell 3000 Index and the Russell 2000 Index. Beginning during reconstitution 2007, companies incorporated in the following countries or regions are also reviewed for eligibility for inclusion: Bahamas, Belize, Bermuda, British Virgin Islands, Cayman Islands, Channel Islands, Cook Islands, Gibraltar, Isle of Man, Liberia, Marshall Islands and Netherlands Antilles. Companies incorporated in these regions are considered Benefits Drive Incorporations (“BDI”) because they typically incorporate in these regions for operations, tax, political or other financial market benefits. However, not all companies incorporated in these regions are eligible for inclusion in the Russell 3000 Index and the Russell 2000 Index. Companies incorporated in these regions must also meet one of the following criteria in order to be considered eligible: (i) the company has the headquarters in the U.S. or (ii) the company’s headquarters is also in the BDI designated region or country and the primary exchange for local shares is in the U.S. For new companies located in the BDI regions eligible for inclusion in the Russell 3000 Index and the Russell 2000 Index, the determination of the company’s primary exchange is based on the average daily dollar trading value, which is the accumulated dollar trading volume divided by the actual number of trading days in the past year. However, primary exchange is only one factor for inclusion if both incorporation and headquarters are in a BDI designated region or if multiple headquarters exist in the SEC filings. If the company is has its headquarters in another country, other than the BDI regions and the U.S., it is not eligible for inclusion regardless of its primary exchange. Headquarters and primary exchanges will be analyzed once a year during reconstitution unless the security is de-listed from the U.S. exchange.

All securities eligible for inclusion in the Russell 3000 Index and the Russell 2000 Index must trade on a major U.S. exchange. Bulletin board, pink-sheets or Over The Counter (OTC) traded securities are not eligible for inclusion. Stocks must trade at or above $1.00 on their primary exchange on May 31^st to be eligible for inclusion during annual reconstitution. However, if a stock falls below $1.00 intra-year, it will not be removed until the next annual reconstitution, provided it is still trading below $1.00 at that time. Preferred stock, convertible preferred stock, redeemable shares, participating preferred stock, paired shares, warrants and rights, and trust receipts are also excluded. Royalty Trusts, limited liability companies, closed-end investment companies (business development companies are eligible), and limited partnerships are also ineligible for inclusion. In addition, Berkshire Hathaway is excluded as a special exception due to its similarity to a mutual fund and lack of liquidity. In general, only one class of securities of a company is eligible for inclusion in the Russell 3000 Index, although exceptions to this general rule have been made where FRC has determined that each class of securities acts independent of the other.

The primary criteria used to determine the list of securities eligible for the Russell 3000 Index is total market capitalization, which is defined as the price of the common shares times the total number of common shares outstanding.

PS-23

Table of Contents

Only common stock is used to determine market capitalization, any other form of shares such as preferred stock, convertible preferred stock, redeemable shares, participating preferred stock, warrants and rights or trust receipts, are excluded from the calculation. Based on closing levels of the company’s common stock on its primary exchange on May 31 of each year, FRC reconstitutes the composition of the Russell 3000 Index using the then existing market capitalizations of eligible companies. As of June 22nd of each year, the Russell 2000 Index is adjusted to reflect the reconstitution of the Russell 3000 Index for that year. In addition, since September 2004, FRC has added initial public offerings to the Russell 3000 Index on a quarterly basis based on market capitalization guidelines established during the most recent reconstitution.

As a capitalization-weighted index, the Russell 2000 Index reflects changes in the capitalization, or market value, of the component stocks relative to the capitalization on a base date. The current Index level is calculated by adding the market values of the Russell 2000 Index’s component stocks, which are derived by multiplying the price of each stock by the number of shares outstanding, to arrive at the total market capitalization of the 2,000 stocks. The total market capitalization is then divided by a divisor, which represents the “adjusted” capitalization of the Russell 2000 Index on the base date of December 31, 1986. To calculate the Russell 2000 Index, closing prices will be used for exchange-traded and Nasdaq stocks. If a component stock is not open for trading, the most recently traded price for that security will be used in calculating the Russell 2000 Index. In order to provide continuity for the Russell 2000 Index’s level, the divisor is adjusted periodically to reflect events including changes in the number of common shares outstanding for component stocks, company additions or deletions, corporate restructurings and other capitalization changes.

The level of the Russell 2000 Index is reported on the AMEX under the symbol “RUT”, on Bloomberg under the symbol “RTY” and on Reuters under the symbol “.RUT”.

Neither ML&Co. nor MLPF&S accepts any responsibility for the calculation, maintenance or publication of the Russell 2000 Index or any successor index. FRC disclaims all responsibility to holders of Notes for any errors or omissions in the calculation and dissemination of the Russell 2000 Index or the manner in which the Russell 2000 Index is applied in determining any Starting Value or Ending Value or any amount payable to you on the maturity date of the Notes.

UNITED STATES FEDERAL INCOME TAXATION

Set forth in full below is the opinion of Sidley Austin LLP, counsel to ML&Co. (“Tax Counsel”). As the law applicable to the U.S. federal income taxation of instruments such as the Notes is technical and complex, the discussion below necessarily represents only a general summary. The following discussion is based upon laws, regulations, rulings and decisions now in effect, all of which are subject to change (including changes in effective dates) or possible differing interpretations. It deals only with Notes held as capital assets and does not purport to deal with persons in special tax situations, such as financial institutions, insurance companies, regulated investment companies, real estate investment trusts, entities classified as partnerships, tax-exempt entities or persons holding Notes in a tax-deferred or tax-advantaged account (except to the extent specifically discussed below), dealers in securities or currencies, traders in securities that elect to mark to market, persons subject to the alternative minimum tax, persons holding Notes as a hedge against currency risks, as a position in a “straddle” or as part of a “hedging”, “conversion” or “integrated” transaction for tax purposes, or persons whose functional currency is not the United States dollar. It also does not deal with holders other than original purchasers (except where otherwise specifically noted). If a partnership holds the Notes, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. Thus, persons who are partners in a partnership holding the Notes should consult their own tax advisors. Moreover, all persons considering the purchase of the Notes should consult their own tax advisors concerning the application of U.S. federal income tax laws to their particular situations as well as any consequences of the purchase, ownership and disposition of the Notes arising under the laws of any other taxing jurisdiction.

As used herein, the term “U.S. Holder” means a beneficial owner of a Note that is for U.S. federal income tax purposes (i) a citizen or resident of the United States, (ii) a corporation (including an entity treated as a corporation for U.S. federal income tax purposes) that is created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income tax regardless of its source, (iv) a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or (v) any other person whose income or gain in respect of a Note is effectively connected with the conduct of a United States trade or business. Certain trusts not described in clause (iv) above in existence on August 20, 1996, that elect to be treated as United States persons will also be U.S. Holders for purposes of the following discussion. As used herein, the term “non-U.S. Holder” means a beneficial owner of a Note that is not a U.S. Holder.

General

There are no statutory provisions, regulations, published rulings or judicial decisions addressing or involving the characterization and treatment, for United States federal income tax purposes, of the Notes or securities with terms substantially the same as the Notes. Accordingly, the proper United States federal income tax characterization and treatment of the Notes is uncertain. Pursuant to the terms of the Notes, ML&Co. and every holder of a Note agree (in the absence of an administrative determination, judicial ruling or other authoritative guidance to the contrary) to characterize and treat a Note for all tax purposes as a pre-paid cash-settled forward contract linked to the level of the Composite Index. In the opinion of Tax Counsel, this characterization and tax treatment of the Notes, although not the only reasonable characterization and tax treatment, is based on reasonable interpretations of law currently in effect and, even if successfully challenged by the Internal Revenue Service (the “IRS”), will not result in the imposition of penalties. The characterization and tax treatment of the Notes described above is not, however, binding on the IRS or the courts. No statutory, judicial or administrative authority directly addresses the characterization and tax treatment of the Notes or instruments similar to the Notes for United States federal income tax purposes, and no ruling is being requested from the IRS with respect to the Notes.

Due to the absence of authorities that directly address instruments that are similar to the Notes, significant aspects of the United States federal income tax consequences of an investment in the Notes are not certain, and no assurance can be given that the IRS or the courts will agree with the characterization and tax treatment described above. Accordingly, prospective purchasers are urged to consult their own tax advisors regarding the United States federal income tax consequences of an investment in the Notes (including alternative characterizations and tax treatments of the Notes) and with respect to any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction. Unless otherwise stated, the following discussion is based on the assumption that the characterization and tax treatment described above is accepted for United States federal income tax purposes.

Tax Treatment of the Notes

Assuming the characterization and tax treatment of the Notes as set forth above, Tax Counsel believes that the following United States federal income tax consequences should result.

Tax Basis. A U.S. Holder’s tax basis in a Note will equal the amount paid by the U.S. Holder to acquire the Note.

Payment on the Maturity Date. Upon the receipt of cash on the maturity date of the Notes, a U.S. Holder will recognize gain or loss. The amount of that gain or loss will be the extent to which the amount of the cash received differs from the U.S. Holder’s tax basis in the Note. It is uncertain whether any such gain or loss would be treated as ordinary income or loss or capital gain or loss. Absent a future clarification in current law (by an administrative determination, judicial ruling or otherwise), where required, ML&Co. intends to report any such gain or loss to the IRS in a manner consistent with the treatment of that gain or loss as capital gain or loss. If any gain or loss is treated as capital gain or loss, then that gain or loss will generally be short-term or long-term capital gain or loss, depending upon the U.S. Holder’s holding period for the Note as of the maturity date. The deductibility of capital losses is subject to certain limitations.

Early Redemption of the Notes. Upon an early redemption of the Notes, a U.S. Holder will recognize gain or loss. The amount of that gain or loss will be the extent to which the amount of the cash received differs from the U.S. Holder’s tax basis in the Note. Any such gain or loss will be treated as capital gain or loss. Any such capital gain or loss will generally be short-term or long-term capital gain or loss, depending upon the U.S. Holder’s holding period for the Note as of the date of such early redemption. As discussed above, the deductibility of capital losses is subject to certain limitations.

Sale or Exchange of the Notes. Upon a sale or exchange of a Note prior to the maturity date of the Notes, a U.S. Holder will generally recognize capital gain or loss equal to the difference between the amount realized on the sale or exchange and the U.S. Holder’s tax basis in the Note so sold or exchanged. Any such capital gain or loss will generally be short-term or long-term capital gain or loss, depending upon the U.S. Holder’s holding period for the Note as of the date of such sale or exchange. As discussed above, the deductibility of capital losses is subject to certain limitations.

Possible Alternative Tax Treatments of an Investment in the Notes

Due to the absence of authorities that directly address the proper characterization and tax treatment of the Notes, no assurance can be given that the IRS will accept, or that a court will uphold, the characterization and tax treatment described above. In particular, the IRS could seek to analyze the United States federal income tax consequences of owning the Notes under Treasury regulations governing contingent payment debt instruments (the “CPDI Regulations”).

If the IRS were successful in asserting that the CPDI Regulations applied to the Notes, the timing and character of income thereon would be significantly affected. Among other things, a U.S. Holder would be required to accrue original issue discount on the Notes every year at a “comparable yield” for us, determined at the time of issuance of the Notes. Furthermore, any gain realized on the maturity date or upon a sale, exchange, early redemption or other disposition of the Notes would generally be treated as ordinary income, and any loss realized on the maturity date or upon a sale, exchange, early redemption or other disposition of the Notes would be treated as ordinary loss to the extent of the U.S. Holder’s prior accruals of original issue discount and capital loss thereafter.

Even if the CPDI Regulations do not apply to the Notes, other alternative United States federal income tax characterizations or treatments of the Notes may also be possible, and if applied could also affect the timing and the character of the income or loss with respect to the Notes. Accordingly, prospective purchasers are urged to consult their tax advisors regarding the United States federal income tax consequences of an investment in the Notes.

Constructive Ownership Law

Section 1260 of the Internal Revenue Code of 1986, as amended (the “Code”), treats a taxpayer owning certain types of derivative positions in property as having “constructive ownership” of that property, with the result that all or a portion of any long-term capital gain recognized by that taxpayer with respect to the derivative position will be recharacterized as ordinary income. In its current form, Section 1260 of the Code does not apply to the Notes. If Section 1260 of the Code were to apply to the Notes in the future, however, the effect on a U.S. Holder of a Note would be to treat all or a portion of any long-term capital gain recognized by the U.S. Holder on the sale, exchange or maturity of a Note as ordinary income. In addition, Section 1260 of the Code would impose an interest charge on any gain that was

recharacterized. U.S. Holders should consult their tax advisors regarding the potential application of Section 1260 of the Code, if any, to the purchase, ownership and disposition of a Note.

Unrelated Business Taxable Income

Section 511 of the Code generally imposes a tax, at regular corporate or trust income tax rates, on the “unrelated business taxable income” of certain tax-exempt organizations, including qualified pension and profit sharing plan trusts and individual retirement accounts. As discussed above, the U.S. federal income tax characterization and treatment of the Notes is uncertain. Nevertheless, in general, if the Notes are held for investment purposes, the amount of income or gain, if any, realized with respect to a Note, or any income that would accrue to a holder of a Note if the Notes were characterized as contingent payment debt instruments (as discussed above), will not constitute unrelated business taxable income. However, if a Note constitutes debt-financed property (as defined in Section 514(b) of the Code) by reason of indebtedness incurred by a holder of a Note to purchase the Note, all or a portion of any income or gain realized with respect to such Note may be classified as unrelated business taxable income pursuant to Section 514 of the Code. Moreover, prospective investors in the Notes should be aware that whether or not any income or gain realized with respect to a Note which is owned by an organization that is generally exempt from U.S. federal income taxation pursuant to Section 501(a) of the Code constitutes unrelated business taxable income will depend upon the specific facts and circumstances applicable to such organization. Accordingly, any potential investors in the Notes that are generally exempt from U.S. federal income taxation pursuant to Section 501(a) of the Code are urged to consult with their own tax advisors concerning the U.S. federal income tax consequences to them of investing in the Notes.

Non-U.S. Holders

Based on the characterization and tax treatment of each Note as a pre-paid cash-settled forward contract linked to the level of the Composite Index, in the case of a non-U.S. Holder, a payment made with respect to a Note on the maturity date will not be subject to United States withholding tax, provided that the non-U.S. Holder complies with applicable certification requirements and that the payment is not effectively connected with a United States trade or business of the non-U.S. Holder. Any capital gain realized upon the sale or other disposition of a Note by a non-U.S. Holder will generally not be subject to United States federal income tax if (i) that gain is not effectively connected with a United States trade or business of the non-U.S. Holder and (ii) in the case of an individual non-U.S. Holder, the individual is not present in the United States for 183 days or more in the taxable year of the sale or other disposition, or the gain is not attributable to a fixed place of business maintained by the individual in the United States, and the individual does not have a “tax home” (as defined for United States federal income tax purposes) in the United States.

As discussed above, alternative characterizations and treatments of the Notes for United States federal income tax purposes are possible. Should an alternative characterization or tax treatment of the Notes, by reason of a change or clarification of the law, by regulation or otherwise, cause payments with respect to the Notes to become subject to withholding tax, ML&Co. will withhold tax at the applicable statutory rate. Prospective non-U.S. Holders of the Notes should consult their own tax advisors in this regard.

Backup Withholding

A beneficial owner of a Note may be subject to backup withholding at the applicable statutory rate of United States federal income tax on certain amounts paid to the beneficial owner unless the beneficial owner provides proof of an applicable exemption or a correct taxpayer identification number, and otherwise complies with applicable requirements of the backup withholding rules.

Any amounts withheld under the backup withholding rules from a payment to a beneficial owner would be allowed as a refund or a credit against the beneficial owner’s United States federal income tax provided the required information is furnished to the IRS.

ERISA CONSIDERATIONS

Each fiduciary of a pension, profit-sharing or other employee benefit plan subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) (a “Plan”), should consider the fiduciary standards of ERISA in the context of the Plan’s particular circumstances before authorizing an investment in the Notes. Accordingly, among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing the Plan.

In addition, we and certain of our subsidiaries and affiliates, including MLPF&S, may be each considered a party in interest within the meaning of ERISA, or a disqualified person within the meaning of the Internal Revenue Code of 1986, as amended (the “Code”), with respect to many Plans, as well as many individual retirement accounts and Keogh plans (also “Plans”). Prohibited transactions within the meaning of ERISA or the Code would likely arise, for example, if the securities are acquired by or with the assets of a Plan with respect to which MLPF&S or any of its affiliates is a party in interest, unless the securities are acquired pursuant to an exemption from the prohibited transaction rules. A violation of these prohibited transaction rules could result in an excise tax or other liabilities under ERISA and/or Section 4975 of the Code for such persons, unless exemptive relief is available under an applicable statutory or administrative exemption.

Under ERISA and various prohibited transaction class exemptions (“PTCEs”) issued by the U.S. Department of Labor, exemptive relief may be available for direct or indirect prohibited transactions resulting from the purchase, holding or disposition of the securities. Those exemptions are PTCE 96-23 (for certain transactions determined by in-house asset managers), PTCE 95-60 (for certain transactions involving insurance company general accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 90-1 (for certain transactions involving insurance company separate accounts), PTCE 84-14 (for certain transactions determined by independent qualified asset managers), and the exemption under new Section 408(b)(17) of ERISA and new Section 4975(d)(20) of the Code for certain arm’s-length transactions with a person that is a party in interest solely by reason of providing services to Plans or being an affiliate of such a service provider (the “Service Provider Exemption”).

Because we may be considered a party in interest with respect to many Plans, the securities may not be purchased, held or disposed of by any Plan, any entity whose underlying assets include plan assets by reason of any Plan’s investment in the entity (a “Plan Asset Entity”) or any person investing plan assets of any Plan, unless such purchase, holding or disposition is eligible for exemptive relief, including relief available under PTCE 96-23, 95-60, 91-38, 90-1, or 84-14 or the Service Provider Exemption, or such purchase, holding or disposition is otherwise not prohibited. Any purchaser, including any fiduciary purchasing on behalf of a Plan, transferee or holder of the securities will be deemed to have represented, in its corporate and its fiduciary capacity, by its purchase and holding of the securities that either (a) it is not a Plan or a Plan Asset Entity and is not purchasing such securities on behalf of or with plan assets of any Plan or with any assets of a governmental, church or foreign plan that is subject to any federal, state, local or foreign law that is substantially similar to the provisions of Section 406 of ERISA or Section 4975 of the Code or (b) its purchase, holding and disposition are eligible for exemptive relief or such purchase, holding and disposition are not prohibited by ERISA or Section 4975 of the Code (or in the case of a governmental, church or foreign plan, any substantially similar federal, state, local or foreign law).

Under ERISA, assets of a Plan may include assets held in the general account of an insurance company which has issued an insurance policy to such plan or assets of an entity in which the Plan has invested. Accordingly, insurance company general accounts that include assets of a Plan must ensure that one of the foregoing exemptions is available. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries or other persons considering purchasing the securities on behalf of or with “plan assets” of any Plan consult with their counsel regarding the availability of exemptive relief under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or the Service Provider Exemption.

Purchasers of the securities have exclusive responsibility for ensuring that their purchase, holding and disposition of the securities do not violate the prohibited transaction rules of ERISA or the Code or any similar regulations applicable to governmental or church plans, as described above.

With respect to the unaudited condensed consolidated interim financial information for the three-month periods ended March 30, 2007 and March 31, 2006, and the three-month and six-month periods ended June 29, 2007 and June 30, 2006 which are incorporated herein by reference, Deloitte & Touche LLP, an independent registered public accounting firm, have applied limited procedures in accordance with the standards of the Public Company Accounting Oversight Board (United States) for a review of such information. However, as stated in their reports included in ML&Co.’s Quarterly Reports on Form 10-Q for the quarters ended March 30, 2007 and June 29, 2007 (which reports include an explanatory paragraph regarding the adoption of Statement of Financial Accounting Standards No. 157, “Fair Value Measurement”, Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115,” and FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109.”) and incorporated by reference herein, they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Deloitte & Touche LLP are not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their reports on the unaudited condensed consolidated interim financial information because those reports are not “reports” or a “part” of the registration statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Act.
