“Leveraged Index Return Notes^®” is a registered service mark of Merrill Lynch & Co., Inc.

“Merrill Lynch Commodity index eXtra^SM – Excess Return” is a service mark and trademark of Merrill Lynch & Co., Inc.

The Leveraged Index Return Notes^® Linked to the Merrill Lynch Commodity index eXtra^SM – Excess Return due February , 2012 (the “Notes”) are senior, unsecured debt securities of Merrill Lynch & Co., Inc. (“ML&Co.”) that provide a leveraged return for investors, if the value of the commodity-based Merrill Lynch Commodity index eXtra^SM – Excess Return (Bloomberg index symbol “MLCXER <Index>“) (the “Index”) increases from the Starting Value of the Index, determined on the Pricing Date, to the Ending Value of the Index determined on the Calculation Day shortly prior to the maturity date of the Notes. Investors must be willing to forego interest payments on the Notes and be willing to accept a repayment that may be less, and potentially significantly less, than the original public offering price of the Notes.

Set forth below are three examples of payment at maturity calculations, assuming a hypothetical Starting Value of 583.80, the closing level of the Index on February 7, 2008, a downside leverage factor of 117.60% and assuming a Participation Rate of 130.0%, the midpoint of the indicated range of 125% and 135%:

Example 1—The hypothetical Ending Value is 50% of the hypothetical Starting Value, less than the Threshold Value:

Example 2—The hypothetical Ending Value is 90% of the hypothetical Starting Value, greater than the Threshold Value:

If the Ending Value is less than the Starting Value but is greater than or equal to the Threshold Value, the Redemption Amount per unit will equal the $10 original public offering price.

Example 3—The hypothetical Ending Value is 120% of the hypothetical Starting Value:

The following table illustrates, for the hypothetical Starting Value of 583.80, a Threshold Value of 85% of the hypothetical Starting Value, and a range of hypothetical Ending Values of the Index:

The table below assumes a Participation Rate of 130.0%, the midpoint of the indicated range of 125% and 135%.

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 Starting Value, Ending Value, Participation Rate and term of your investment.

An investment in the Notes involves significant risks. The following is a list of certain of the risks involved in investing in the Notes. You should carefully review the more detailed explanation of risks relating to the Notes in the “Risk Factors” sections included in the product supplement and MTN prospectus supplement identified below under “Additional Note Terms”. We also urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the Notes.

There is no assurance that the calculation principles of the Index will result in the Index accurately reflecting commodity market performance

The methodology and criteria used to determine the composition of the Index, the weights of the various Index Components and the calculation of the level of the Index are designed to allow the Index to serve as a measure of commodity market performance. However, the Index has only recently been introduced and has a limited history. It is possible that the methodology and criteria applied in connection with the Index will not accurately reflect commodity market performance and that the trading of or investments in products based on or related to the Index, such as the Notes, will not correlate with commodity market performance generally.

Certain commodity prices have recently been at historical highs and there is no assurance that such price levels will be sustained or repeated.

The price levels of certain types of commodities, particularly energy products, have recently been at historic highs, which tends to increase the level of the Index. There can be no assurance that these price levels will be sustained or repeated in future periods, and the level of the Index could decline in the future.

The Index is composed of futures contracts on physical commodities. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, commodity futures contracts have a set expiration date and normally specify a certain date for delivery of the underlying physical commodity. In the case of the Index, as the exchange-traded futures contracts that comprise the Index approach the month before expiration, they are replaced by contracts that have a later expiration. This process is referred to as “rolling”. If the market for these contracts is (putting aside other considerations) in “backwardation”, where the prices are lower in the distant delivery months than in the nearer delivery months, the sale of the nearer delivery month contract would take place at a price that is higher than the price of the distant delivery month contract, thereby creating a positive “roll yield”. There is no indication that these markets will consistently be in backwardation or that there will be roll yield in future performance. Instead, these markets may trade in “contango.” Contango markets are those in which the prices of contracts are higher in the distant delivery months than in the nearer delivery months. Certain of the commodities included in the Index have historically traded in contango markets. Contango (or the absence of backwardation) in the commodity markets would result in negative “roll yields” which would adversely affect the level of the Index and the value of the Notes.

The Index is designed as a broad-based index of commodity market performance. The current calculation principles applicable to the Index prohibit any market sector from comprising more than 60% of the weight of the index at any time, in order to promote the diversification of the Index Commodities (as defined below). However, the energy sector currently accounts for approximately 60% of the Index and base and precious metals account for over 18%. Accordingly, a decline in value in such raw materials would adversely affect the performance of the Index.

Technological advances or the discovery of new oil reserves could lead to increases in worldwide production of oil and corresponding decreases in the price of crude oil. In addition, further development and commercial exploitation of alternative energy sources, including solar, wind or geothermal energy, could lessen the demand for crude oil products and result in lower prices. Absent amendment of the Index to lessen or eliminate the concentration of existing energy contracts in the Index or to broaden the Index to account for such developments, the level of the Index and hence the value of the Notes could decline.

The Index Manager, an affiliate of ML&Co., may from time to time modify the methodology for determining the composition and calculation of the Index

Merrill Lynch Commodities, Inc. (the “Index Manager”) retains the discretion to modify the methodology for determining the composition and the level, of the Index, at any time. The Index Manager expects to make such modifications from time to time. It is possible that certain of these modifications will adversely affect the level of the Index.

The Notes are linked to the Merrill Lynch Commodity index eXtra – Excess Return (Bloomberg symbol “MLCXER”), not the Merrill Lynch Commodity index eXtra – Spot Return (Bloomberg symbol “MLCXSP”) or the Merrill Lynch Commodity index eXtra – Total Return (Bloomberg symbol “MLCXTR”)

The Notes are linked to the Merrill Lynch Commodity index eXtra – Excess Return (Bloomberg symbol “MLCXER”), which we refer to in this term sheet as the “Index.” The Index reflects both price movements as well as roll yields. By comparison, the Merrill Lynch Commodity index eXtra – Spot Return tracks only price movements of the Index Components, and the Merrill Lynch Commodity index eXtra – Total Return includes commodity price movements, a roll-return component and a U.S. Treasury-bill return component to measure fully collateralized commodity futures investment. Because the Notes are linked to the Index and not the Merrill Lynch Commodity index eXtra – Total Return, the value of the Notes will not reflect the total return feature.

One of our affiliates, Merrill Lynch, Pierce, Fenner & Smith Limited, is the Index Publisher, and another of our affiliates, Merrill Lynch Commodities, Inc., is the Index Manager. In certain circumstances, the Index Publisher’s and the Index Manager’s roles as affiliates of ML&Co. and their responsibilities with respect to the Index could give rise to conflicts of interest. Even though the Index will be calculated in accordance with certain principles, its calculation and maintenance require that certain judgments and decisions be made. Our affiliates, Merrill Lynch, Pierce, Fenner & Smith Limited, as Index Publisher and, thus, calculation agent of the Index, and Merrill Lynch Commodities, Inc., as Index Manager, will be responsible for these judgments and decisions. As a result, the determinations made by the Index Publisher and/or the Index Manager could affect the level of the Index.

Further, Merrill Lynch Commodities, Inc. faces a potential conflict of interest between its role as Index Manager and its active role in trading commodities and derivatives instruments based upon the Index Commodities.

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.

You may wish to consider an investment in the Notes if:

You anticipate that the value of the Index will appreciate from the Starting Value to the Ending Value.

You accept that your investment may result in a loss, which could be significant, if the value of the Index decreases from the Starting Value to an Ending Value that is less than the Threshold Value.

You are willing to forego interest payments on the Notes, such as fixed or floating rate interest paid on traditional interest bearing debt securities.

You want exposure to the Index with no expectation of any rights with respect to any futures contracts or commodities included in or tracked by the Index.

You are willing to accept that a trading market for the Notes is not expected to develop.

The Notes may not be appropriate investments for you if:

You anticipate that the value of the Index will depreciate from the Starting Value to the Ending Value or that the value of the Index will not appreciate sufficiently over the term of the Notes to provide you with your desired return.

You are seeking 100% principal protection or preservation of capital.

You seek interest payments or other current income on your investment.

You want an investment that provides you with rights with respect to the futures contracts or commodities included in or tracked by the Index.

You want assurances that there will be a liquid market if and when you want to sell the Notes prior to maturity.

We may deliver the Notes against payment therefor in New York, New York on a date that is in excess of than three business days following the Pricing Date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement on the Notes occurs more than three business days from the Pricing Date, purchasers who wish to trade Notes more than three business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

If you place an order to purchase these offered securities, you are consenting to each of MLPF&S and its broker-dealer affiliate First Republic Securities Company, LLC acting as a principal in effecting the transaction for your account. MLPF&S is acting as an underwriter and/or selling agent for this offering and will receive underwriting compensation from the issuer of the securities.

MLPF&S and First Republic Securities Company, LLC, each a broker-dealer subsidiary of ML&Co., are members of the Financial Industry Regulatory Authority, Inc. (formerly the National Association of Securities Dealers, Inc. (the “NASD”)) and will participate in distribution of the Notes. Accordingly, offerings of the Notes will conform to the requirements of NASD Rule 2720.

MLPF&S and First Republic Securities Company, LLC may use this Note Prospectus for offers and sales in secondary market transactions and market-making transactions in the Notes but are not obligated to engage in such secondary market transactions and/or market-making transactions. MLPF&S and First Republic Securities Company, LLC may act as principal or agent in these transactions, and any such sales will be made at prices related to prevailing market prices at the time of the sale.

All disclosure in this term sheet regarding the Index, including without limitation, its make-up, method of calculation and changes in its components, is derived from information made available by the Index Manager and MLPF&S, in its capacity as “Index Publisher”, each an affiliate of ML&Co. This information reflects the policies of the Index Manager and Index Publisher and is subject to change by the Index Manager and Index Publisher at their discretion. The Index Manager and Index Publisher have no obligation to continue to publish, and may discontinue publication of, the Index.

The Index was created by the Index Manager in conjunction with the Index Publisher in 2006 and is designed to provide a benchmark for commodity market performance and for investment in commodities as an asset class. The Index is comprised of futures contracts on physical commodities (each an “Index Commodity”). A commodity futures contract is an agreement that provides for the purchase and sale of a specified type and quantity of a commodity during a stated delivery month for a fixed price. In the case of the Index, as the exchange traded futures contracts that comprise the Index (the “Index Components”) approach the month before expiration, they are replaced by contracts that have later expiration. This process is referred to as “rolling”. The Index rolls over a 15 day period each month. The Index is an excess return index that factors in both price movements as well as roll yields.

The Index Manager constructed the Index based primarily on the liquidity of the Index Components and the value of the global production of each Index Commodity. The Index Manager believes that these criteria allow the Index to reflect the general significance of the Index Commodities in the global economy, differentiating between “upstream” and “downstream” commodities, with a particular emphasis on downstream commodities (i.e., those that are derived from other Index Commodities). The Index composition and weights are typically determined once a year and applied once at the start of each year in January. See the section entitled “Construction—Contract Selection—Weighting”. The methodology for determining the composition, weighting or value of the Index and for calculating its level is subject to modification by the Index Manager and Index Publisher, respectively, at any time. The Index Manager has indicated that it expects to modify the Index only in rare occasions in order to maintain stability and comparability.

The Index contains six market sectors identified by the Index Manager: (1) energy; (2) base metals; (3) precious metals; (4) grains & oil seeds; (5) livestock; and (6) soft commodities & others (each a “Market Sector”). Each Market Sector contains a minimum of two and a maximum of four Index Components, selected by liquidity.

The Index Manager initially selected six exchanges, on the basis of liquidity, geographical location and commodity type (the “Selected Exchanges”). To be considered for selection, an exchange must be located in a country that is a member of the Organization for Economic Co-Operation and Development. The exchange must also be a principal trading forum, based on relative liquidity, for U.S. dollar-denominated futures contracts on major physical commodities. The six exchanges currently are: (1) the (a) the NYMEX and (b) the COMEX divisions of the New York Mercantile Exchange (the “NYMEX”); (2) the Chicago Mercantile Exchange (the “CME”); (3) the Chicago Board of Trade (the “CBOT”); (4) the London Metals Exchange (the :LME”); (5) the ICE Futures (formerly known as the International Petroleum Exchange); and (6) the New York Board of Trader (the “NYBOT”).

To be an “Eligible Contract”, a commodity futures contract must not only be traded on a Selected Exchange, it must also satisfy the requirements for inclusion. In order to be an Eligible Contract, a contract must generally satisfy all of the following requirements:

An Eligible Contract is selected for inclusion in the Index only after application of the requirements for a minimum and maximum number of contracts from each Market Sector. A contract that does not otherwise satisfy all of the foregoing requirements may nevertheless be determined by the Index Manager to be an Eligible Contract and included in the Index if the inclusion of the contract is, in the judgment of the Index Manager, necessary or appropriate to maintain the integrity of the Index and/or to realize the objectives of the Index. Every year the Index Manager will compile a list of all commodity futures contracts traded on the Selected Exchanges and a list of the Eligible Contracts that satisfy the foregoing criteria. This list will be used to determine the commodities futures contracts which will be included in the Index.

The Index Manager distinguishes the Eligible Contracts by their liquidity. Liquidity is measured by a contract’s Total Trading Volume and the value of that trading volume. The “Total Trading Volume” (“TTV”) with respect to each contract traded on a Selected Exchange is equal to the sum of the daily trading volumes in all expiration months of the contract on each day during the most recent twelve-month period beginning on July 1 and ending on June 30. The “Contract Size” (“CS”) is the number of standard physical units of the underlying commodity represented by one contract. For example, the Contract Size of a crude oil futures contract is 1,000 barrels. The “Average Reference Price” (“ARP”), which is used to determine the value of the Total Trading Volume, is the average of the Reference Prices of the Front-Month Contract for an Index Component on each Trading Day during the twelve month period beginning on July 1 and ending on June 30 of each year. A “Front-Month Contract” on any given day is the futures contract expiring on the first available contract expiration month after the date on which the determination is made. A “Trading Day” means any day on which the relevant Selected Exchange is open for trading. “Liquidity” (“LIQ”) is therefore equal to the Total Trading Volume, multiplied by the Contract Size with respect to each contract, multiplied by the Average Reference Price for each contract:

Once the Liquidity is determined, the Eligible Contracts are listed in order of their Liquidity, from highest to lowest. All six Index Market Sectors must be represented by a minimum of two and a maximum of four Eligible Contracts. “Redundant Contracts” are less liquid Eligible Contracts representing a similar commodity and are excluded. For instance, the list of Index Components includes an Eligible Contract on WTI crude oil but excludes Brent crude oil as a Redundant Contract.

The selection of Eligible Contracts and determination of the Index Components occurs once a year and the results for the following calendar year will be announced before the first NYMEX Business Day of November. Based on this selection process, the Index may include from 12 to 22 commodity futures contracts. The Index includes the following 18 contracts:

For purposes of the preceding paragraph only, a “NYMEX Business Day” is any day that the New York Mercantile Exchange rules define as a trading day.

The Index Manager determines the weight of each Index Component on the basis of the global production of the related Index Commodity, provided that the contract reflects global prices for that Index Commodity. In some cases, however, the Index Components only have pricing links to a limited number of markets around the world. For instance, the NYMEX natural gas contract primarily represents the U.S. market and the surrounding North American markets in Canada and Mexico. In addition, some European gas markets, such as the U.K., are developing an increasing link to U.S. natural gas prices through the liquefied natural gas market. As a result, rather than using production of natural gas in the world or in the U.S. to assign a weight to the natural gas contract in the Index, the Index Manager has aggregated U.S., Canadian, Mexican and U.K. natural gas production. Similarly, the Index Manager found that U.S. livestock prices can be affected by local issues such as disease and trade restrictions, so it limited the livestock component of the Index to production of cattle and hogs in the United States, instead of using global production weights.

Also, certain commodities are derived from other commodities in various forms. For example, gasoline and heating oil are produced from crude oil, and, because livestock feed on corn and other grains, they are to an extent derived from agricultural commodities. To avoid “double counting” of such commodities like crude oil or grains used as livestock feed, the Index Manager differentiates between “upstream” and “downstream” commodities and adjusts the global production quantity of the Index Commodities accordingly.

The weight of any given Market Sector in the Index is capped at 60% of the overall Index and a minimum weight of 3% is applicable to each Market Sector. Even though the Index is designed to reflect the significance of the underlying commodities in the global economy, each Market Sector maintains these limits in an attempt to control volatility.

The weights of the Market Sectors and Index Components for 2008, announced December 12, 2007, were:

Each Index Component is rolled into the next available contract month in advance of the month in which expiration of the contract occurs. The rolling process takes place over a fifteen day period during each month prior to the relevant expiration month for each contract. The rolling process is spread out to limit the effect it might have on the market through the purchase and sale of contracts by investors who might attempt to replicate the performance of the Index. The rolling of contracts is effected on the same days for all Index Components, regardless of exchange holiday schedules, emergency closures or other events that could prevent trading in such contracts. If an Index Component is rolled on a day on which the relevant contract is not available for trading, the roll will be effected on the basis of the most recent available settlement price.

The Merrill Lynch Commodity Index Advisory Committee (the “Advisory Committee”), comprised of individuals internal and external to Merrill Lynch, is expected to assist the Index Manager and Index Publisher in connection with the application of the Index principles, advise the Index Manager and Index Publisher on the administration and operation of the Index, and make recommendations to the Index Manager and Index Publisher as to any modifications to the Index methodology that may be necessary or appropriate.

The Advisory Committee is scheduled to meet once a year and may meet more often at the request of the Index Manager and Index Publisher. The Advisory Committee will advise the Index Manager and Index Publisher with respect to the inclusion/exclusion of any of the exchanges and contracts in the Index, any changes to the composition of the Index or in the weights of the Index Components, and any changes to the calculation procedures applicable to the Index. The Advisory Committee will act solely in an advisory and consulting capacity. All decisions relating to the composition, weighting or value of the Index are made by the Index Manager and Index Publisher.

The Index was launched in June 2006 and, accordingly, there is no actual historical data on the Index prior to June 2006. The following graph sets forth the hypothetical historical performance of the Index in the period from January 2003 through June 2006 and the actual performance of the Index in the period from June 2006 to January 2008. This hypothetical and historical data on the Index is not necessarily indicative of the future performance of the Index or what the value of the Notes may be. Any historical upward or downward trend in the level of the Index during any period set forth below is not an indication that the Index is more or less likely to increase or decrease at any time over the term of the Notes. On February 7, 2008, the closing level of the Index was 583.80.

Merrill Lynch, Pierce, Fenner & Smith Limited, the Index Publisher, has entered into a license agreement granting to Merrill Lynch & Co., Inc. a non-exclusive license to use the Index in connection with certain financial products. Merrill Lynch & Co. is an authorized sub-licensee.

Merrill Lynch, Pierce, Fenner & Smith Limited, as Index Publisher, and Merrill Lynch Commodities, Inc., as Index Manager, make no representation or warranty, express or implied, to depositors or any member of the public regarding the advisability of purchasing Notes, particularly, or the ability of the Index to track general commodity market performance. The Index is determined, composed and calculated by the Index Publisher and the Index Manager without regard to the Notes. The Index Publisher and the Index Manager have no obligation to take the needs of the depositors into consideration in determining, composing or calculating the Index. The Index Publisher and the Index Manager are not responsible for and have not participated in the determination of the timing of, prices at or quantities of the Notes to be issued. The Index Publisher and the Index Manager have no obligation or liability in connection with the administration and marketing of the Notes.

Set forth below is a summary of certain U.S. federal income tax considerations relating to an investment in the Notes. The following summary is not complete and is qualified in its entirety by the discussion under the section entitled “United States Federal Income Taxation” in the accompanying product supplement LIRN-2 and MTN prospectus supplement, which you should carefully review prior to investing in the Notes.

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 Index. 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 Internal Revenue Service (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.

Payment on the Maturity Date. Assuming that the Notes are properly characterized and treated as pre-paid cash-settled forward contracts linked to the level of the Index, upon the receipt of cash on the maturity date of the Notes, a U.S. Holder (as defined in the accompanying product supplement

LIRN-2) will recognize gain or loss. The amount of such 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. A U.S. Holder’s tax basis in a Note generally will equal the amount paid by the U.S. Holder to purchase 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 such gain or loss as capital gain or loss. If such gain or loss is treated as capital gain or loss, then any such gain or loss will be long-term capital gain or loss if the U.S. Holder has held the Note for more than one year as of the maturity date.

Sale or Exchange of the Notes. Assuming that the Notes are properly characterized and treated as pre-paid cash-settled forward contracts linked to the level of the Index, 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 in an amount equal to the difference between the amount realized on such sale or exchange and such U.S. Holder’s tax basis in the Note so sold or exchanged. Any such capital gain or loss will be long-term capital gain or loss if the U.S. Holder has held the Note for more than one year as of the date of such sale or exchange.

Possible Future Tax Law Changes. On December 7, 2007, the IRS released a notice that could possibly affect the taxation of holders of the Notes. According to the notice, the IRS and the U.S. Department of the Treasury (the “Treasury Department”) are actively considering, among other things, whether the holder of an instrument having terms similar to the Notes should be required to accrue either ordinary income or capital gain on a current basis, and they are seeking comments on the subject. It is not possible to determine what guidance they will ultimately issue, if any. It is possible, however, that under such guidance, holders of instruments having terms similar to the Notes will ultimately be required to accrue income currently and this could be applied on a retroactive basis. The IRS and the Treasury Department are also considering other relevant issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals, whether the tax treatment of such instruments should vary depending upon whether or not such instruments are traded on a securities exchange, whether such instruments should be treated as indebtedness, whether the tax treatment of such instruments should vary depending upon the nature of the underlying asset, and whether the special “constructive ownership rules” contained in Section 1260 of the Internal Revenue Code, as amended might be applied to such instruments. Holders are urged to consult their tax advisors concerning the significance, and the potential impact, if any, of the above considerations to their investment in the Notes. ML&Co. intends to continue to treat the Notes for U.S. federal income tax purposes in accordance with the treatment described herein unless and until such time as the Treasury Department and IRS determine that some other treatment is more appropriate.

Prospective purchasers of the Notes should consult their own tax advisors concerning the tax consequences, in light of their particular circumstances, under the laws of the United States and any other taxing jurisdiction, of the purchase, ownership and disposition of the Notes. See the discussion under the section entitled “United States Federal Income Taxation” in the accompanying product supplement LIRN-2.

The consolidated financial statements and management’s report on the effectiveness of internal control over financial reporting, included as Exhibit 99.1 in the Current Report on Form 8-K dated November 13, 2007 (“November 13, 2007 Form 8-K”) and the related financial statement schedule included in the Merrill Lynch & Co., Inc.’s Form 10-K for the year ended December 29, 2006 are incorporated in this prospectus by reference, and have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports, which are incorporated herein by reference (which reports (1) express an unqualified opinion on the consolidated financial statements and the related financial statement schedule and include an explanatory paragraph regarding the change in accounting method in 2006 for share-based payments to conform to Statement of Financial Accounting Standard No. 123 (revised 2004), Share-Based Payment, (2) express an unqualified opinion on management’s assessment regarding the effectiveness of internal control over financial reporting, and (3) express an unqualified opinion on the effectiveness of internal control over financial reporting), and have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing.

With respect to the unaudited condensed consolidated interim financial information for the three-month periods ended March 30, 2007 and March 31, 2006, the three-month and six-month periods ended June 29, 2007 and June 30, 2006, and the three-month and nine-month periods ended September 28, 2007 and September 29, 2006 which is 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 for the quarters ended March 30, 2007, included as Exhibit 99.3 in the November 13, 2007 Form 8-K, June 29, 2007, included as Exhibit 99.2 in the November 13, 2007 Form 8-K, and September 28, 2007 included in ML&Co.’s Quarterly Reports on Form 10-Q (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.
