Preliminary Term Sheet

The Notes will have the terms specified in this term sheet as supplemented by the documents indicated herein under “Additional Note Terms” (together the “Note Prospectus”). Investing in the Notes involves a number of risks. See “ Risk Factors” on page TS-5 of this term sheet and beginning on page PS-4 of product supplement ARN-4.

In connection with this offering, each of Merrill Lynch, Pierce, Fenner & Smith Incorporated and its broker-dealer affiliate First Republic Securities Company, LLC is acting in its capacity as a principal.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this Note Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

*Depending on the date the Notes are priced for initial sale to the public (the “Pricing Date”), which may be in February or March, the settlement date may occur in February or March and the maturity date may occur in April or May. Any reference in this term sheet to the month in which the settlement date or maturity date will occur is subject to change as specified above.

“Accelerated Return Notes^SM” is a service mark of Merrill Lynch & Co., Inc.

“MSCI Brazil Index^SM” is the exclusive property of MSCI, Inc. and has been licensed for use by Merrill Lynch, Pierce, Fenner & Smith Incorporated. Merrill Lynch & Co., Inc. is an authorized sublicensee.

The Accelerated Return Notes^SMLinked to the MSCI Brazil Index^SM due May , 2009 (the “Notes”) are senior, unsecured debt securities of Merrill Lynch & Co., Inc. that provide a leveraged return for investors, subject to a cap, if the level of the MSCI Brazil Index^SM (the “Index”) increases moderately from the Starting Value of the Index, determined on the Pricing Date, to the Ending Value of the Index, determined on Calculation Days shortly prior to the maturity date of the Notes. Investors must be willing to forego interest payments on the Notes and willing to accept a return that is capped or a repayment that is 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 3,523.56, the closing level of the Index on January 29, 2008, and a Capped Value of $13.40, the midpoint of the range of $13.20 and $13.60.

Example 1—The hypothetical Ending Value is 80% of the hypothetical Starting Value:

Example 2—The hypothetical Ending Value is 103% of the hypothetical Starting Value:

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

Payment at maturity (per unit) = $13.40 (Payment at maturity cannot be greater than the Capped Value)

The following table illustrates, for a hypothetical Starting Value of 3,523.56 (the closing level of the Index on January 29, 2008) and a range of hypothetical Ending Values of the Index:

The table below assumes a Capped Value of $13.40, the midpoint of the range of $13.20 and $13.60.

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, Capped Value 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.

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 Index will appreciate moderately from the Starting Value to the Ending Value.

You accept that your investment may result in a loss, which could be significant, if the level of the Index decreases from the Starting Value to the Ending Value.

You accept that the return on the Notes will not exceed the Capped 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 dividends or other benefits of owning the underlying securities.

You are willing to accept that there is no assurance that the Notes will be listed on AMEX and that any listing will not ensure that a trading market will develop for the Notes or that there will be liquidity in the trading market.

The Notes may not be appropriate investments for you if:

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

You are seeking principal protection or preservation of capital.

You seek a return on your investment that will not be capped at a percentage that will be between 32% and 36%.

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

You want to receive dividends or other distributions paid on the stocks included in 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 greater 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 the 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. MLPF&S and First Republic Securities Company, LLC may act as principal or agent in these transactions, and the sales will be made at prices related to prevailing market prices at the time of the sale.

All disclosure contained in this term sheet regarding the MSCI Indices including, without limitation, their make-up, method of calculation and changes in components, is derived from the MSCI Global Investable Market Indices Methodology Book published by MSCI Inc. (“MSCI”) in December 2007 and other publicly available information. This information reflects the policies of MSCI, as stated in this publicly available information, and is subject to change by MSCI at its discretion. MSCI has no obligation to continue to publish, and may discontinue publication of, the MSCI Indices. ML&Co. and MLPF&S have not independently verified and make no representation as to the accuracy or completeness of such information. None of ML&Co., the calculation agent and MLPF&S accepts any responsibility for the calculation, maintenance or publication of the MSCI Indices or any successor indices.

MSCI Indices were founded in 1969 by Capital International S.A. as the first international performance benchmarks constructed to facilitate accurate comparison of world markets. Morgan Stanley acquired the rights to the indices and data from Capital International in 1986. In November 1998, Morgan Stanley transferred all rights to the MSCI indices to Morgan Stanley Capital International Inc., which was later succeeded by MSCI. The MSCI Indices have covered the world’s developed markets since 1969 and, in 1988, MSCI commenced coverage of the emerging markets. MSCI applies the same criteria and calculation methodology across all markets for all equity indices, developed and emerging.

In March 2006, MSCI announced enhancements to the methodology of its Global Investable Market Indices methodology, by moving from a sampled multi-cap approach to an approach targeting exhaustive coverage with non-overlapping size and style segments. The MSCI Standard and MSCI Small Cap Indices, along with the other MSCI equity indices based on them, will transition to the Global Investable Market Indices methodology described below. The indices will transition in two phases. The first phase was completed on November 30, 2007 and the second purports to be completed by May 30, 2008. The transition will be synchronized for all market and composite indices with the exception of the MSCI Euro and Pan-Euro Indices which transitioned in one phase as of the close of November 30, 2007.

At the end of the transition period, the MSCI Standard Indices will be composed of the MSCI Large Cap and Mid Cap Indices. The current MSCI Small Cap Index will transition to the MSCI Small Cap Index resulting from the Global Investable Market Indices methodology, and will contain no overlap with constituents of the transitioned MSCI Standard Indices. In addition, under the MSCI Global Investable Market Indices methodology, there will be new Small Cap Indices covering Emerging Markets countries. There will also be new MSCI Value and Growth Indices constructed from the Small Cap Index Series for both Emerging and Developed Markets. Together, the relevant MSCI Large Cap, Mid Cap and Small Cap Indices will make up the MSCI Investable Market Index for each country, composite, sector, and style index that MSCI offers.

MSCI undertakes an index construction process, which involves: (i) defining the Equity Universe; (ii) determining the Market Investable Equity Universe for each market; (iii) determining market capitalization size segments for each market; (iv) applying Index Continuity Rules for the Standard Index; (v) creating style segments within each size segment within each market; and (vi) classifying securities under the Global Industry Classification Standard (the “GICS”).

(i) Identifying Eligible Equity Securities: The Equity Universe initially looks at securities listed in any of the countries in the MSCI Global Index Series, which will be classified as either Developed Markets (DM) or Emerging Markets (EM). All listed equity securities, or listed securities that exhibit characteristics of equity securities, except mutual funds, ETFs, equity derivatives, limited partnerships, and most investment trusts are eligible for inclusion in the Equity Universe. Real Estate Investment Trusts (REITs) in some countries and certain income trusts in Canada are also eligible for inclusion.

(ii) Country Classification of Eligible Securities: Each company and its securities (i.e., share classes) is classified in one and only one country, which allows for a distinctive sorting of each company by its respective country.

A Market Investable Equity Universe for a market is derived by applying investability screens to individual companies and securities in the Equity Universe that are classified in that market. A market is equivalent to a single country, except in DM Europe, where all DM countries in Europe are aggregated into a single market for index construction purposes. Subsequently, individual DM Europe country indices within the MSCI Europe Index are derived from the constituents of the MSCI Europe Index under the Global Investable Market Indices methodology.

The investability screens used to determine the Investable Equity Universe in each market are as follows:

(i) Equity Universe Minimum Size Requirement: This investability screen is applied at the company level. In order to be included in a Market Investable Equity Universe, a company must have the required minimum full market capitalization.

(ii) Equity Universe Minimum Float-Adjusted Market Capitalization Requirement: This investability screen is applied at the individual security level. To be eligible for inclusion in a Market Investable Equity Universe, a security must have a free float-adjusted market capitalization equal to or higher than 50% of the Equity Universe Minimum Size Requirement.

(iii) DM and EM Minimum Liquidity Requirement: This investability screen is applied at the individual security level. To be eligible for inclusion in a Market Investable Equity Universe, a security must have adequate liquidity. The Annualized Traded Value Ratio (ATVR), a measure which offers the advantage of screening out extreme daily trading volumes and taking into account the free float-adjusted market capitalization size of securities, is used to measure liquidity. In the calculation of the ATVR, the trading volumes in depository receipts associated with that security, such as ADRs or GDRs, are also considered. A minimum liquidity level of 20% ATVR is required for inclusion of a security in a Market Investable Equity Universe of a Developed Market and a minimum liquidity level of 15% ATVR is required for inclusion of a security in a Market Investable Equity Universe of an Emerging Market.

(iv) Global Minimum Foreign Inclusion Factor Requirement: This investability screen is applied at the individual security level. To be eligible for inclusion in a Market Investable Equity Universe, a security’s Foreign Inclusion Factor (FIF) must reach a certain threshold. The FIF of a security is defined as the proportion of shares outstanding that is available for purchase in the public equity markets by international investors. This proportion accounts for the available free float of and/or the foreign ownership limits applicable to a specific security (or company). In general, a security must have an FIF equal to or larger than 0.15 to be eligible for inclusion in a Market Investable Equity Universe.

(v) Minimum Length of Trading Requirement: This investability screen is applied at the individual security level. For an IPO to be eligible for inclusion in a Market Investable Equity Universe, the new issue must have started trading at least four months before the implementation of the initial construction of the index or at least three months before the implementation of a Semi-Annual Index Review. This requirement is applicable to small new issues in all markets. Large IPOs are not subject to the Minimum Length of Trading Requirement and may be included in a Market Investable Equity Universe and the Standard Index outside of a Quarterly or Semi-Annual Index Review.

Once a Market Investable Equity Universe is defined, it is segmented into the following size-based indices:

Creating the Size Segment Indices in each market involves the following steps: (i) defining the Market Coverage Target Range for each size segment; (ii) determining the Global Minimum Size Range for each size segment; (iii) determining the Market Size-Segment Cutoffs and associated Segment Number of Companies; (iv) assigning companies to the size segments; and (v) applying final size-segment investability requirements.

In order to achieve index continuity, as well as provide some basic level of diversification within a market index, notwithstanding the effect of other index construction rules contained herein, a minimum number of five constituents will be maintained for a DM Standard Index and a minimum number of three constituents will be maintained for an EM Standard Index.

All securities in the investable equity universe are classified into Value or Growth segments using the MSCI Global Value and Growth methodology, which uses multiple factors to identify value and growth characteristics. The value investment style characteristics use the following three variables for index construction: book value to price ratio, 12-month forward earnings to price ratio, and dividend yield. The growth investment style characteristics use the following five variables for index construction: long-term forward earnings per share (“EPS”) growth rate, short-term EPS growth rate, current internal growth rate, long-term historical EPS growth trend, and long-term historical sales per share growth trend.

All securities in the Global Investable Equity Universe are assigned to the industry that best describes their business activities. To this end, MSCI has designed, in conjunction with Standard & Poor’s, the Global Industry Classification Standard (GICS). Under the GICS, each company is assigned uniquely to one sub-industry according to its principal business activity. Therefore, a company can only belong to one industry grouping at each of the four levels of the GICS.

The MSCI Global Investable Market Indices are maintained with the objective of reflecting the evolution of the underlying equity markets and segments on a timely basis, while seeking to achieve index continuity, continuous investability of constituents and replicability of the indices, and index stability and low index turnover.

(i) Semi-Annual Index Reviews (SAIRs) in May and November of the Size Segment and Global Value and Growth Indices which include:

(ii) Quarterly Index Reviews (QIRs) in February and August of the Size Segment Indices aimed at:

(iii) Ongoing event-related changes are generally implemented in the indices as they occur. Significantly large IPOs are included in the indices after the close of the company’s tenth day of trading.

MSCI will transition the current MSCI GCC Countries Indices to the enhanced MSCI GCC Countries Indices Methodology as described above. The transition of the MSCI GCC Countries Indices to the enhanced MSCI GCC Countries Indices Methodology will occur in a single phase, the second phase, which will be implemented as of the close of May 30, 2008. The final additions and deletions of constituents will be announced at least four weeks in advance of their implementation.

During the transition period, MSCI Provisional Standard and Provisional Small Cap Indices will be provided to assist investors in understanding the changes that would occur if the MSCI Global Investable Market Indices methodology were immediately implemented in the current MSCI Standard and Small Cap Indices. The Provisional Indices also provide increased flexibility to current investors who wish to transition to the Global Investable Market Indices methodology on their own schedule. Moreover, the Provisional Standard and Provisional Small Cap Indices and the new Size and Style Segment Indices that will be created based on this methodology are official MSCI indices and as such can be used for a variety of purposes, including as the basis for new investment mandates and for investment vehicles such as passive mutual funds, exchange traded funds and listed and over-the-counter derivative contracts.

The MSCI Brazil Index (the “Index”) is published by MSCI and is a free float-adjusted market capitalization index intended to measure the performance of equity markets in Brazil. The Index is published in real time every 60 seconds during market trading hours. The Index has a base date of December 31, 1987, an initial value of 100, and is calculated in US dollars. The Index is published by Bloomberg under the index symbol “MXBR”. As of January 14, 2008, the five largest sector weights were: Materials (30.38%), Energy (28.56%), Financials (18.94%), Utilities (5.52%) and Consumer Staples (5.09%).

The following graph sets forth the historical performance of the Index in the period from January 2003 through December 2007. This 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 January 29, 2008, the closing level of the Index was 3,523.56.

MLPF&S and MSCI have entered into or, to the extent required, will enter into a non-exclusive license agreement providing for the license to MLPF&S and certain of its affiliates (including ML&Co.), in exchange for a fee, of the right to use certain indices calculated by MSCI in connection with the issuance and marketing of securities, including the Notes.

The license agreement provides that the following information must be set forth in this term sheet:

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 ARN-4 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 ARN-4) 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 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.

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 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.

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 of 1986, 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 ARN-4.

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 ML&Co.’s Form 10-K for the year ended December 29, 2006 are incorporated in this term sheet 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. 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 (the “Act”) 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.
