Summary

The Accelerated Return Bear Market Notes Linked to the S&P 500^® Index due January     , 2010 (the “Notes”) are senior unsecured debt securities of Merrill Lynch & Co., Inc. (“ML&Co.”) and are not guaranteed or insured by the Federal Deposit Insurance Corporation (“FDIC”) or secured by collateral. The Notes will rank equally with all of our other unsecured and unsubordinated debt, and any payments due on the Notes, including any repayment of principal, will be subject to the credit risk of ML&Co. The Notes are designed for, but not limited to, investors (i) who anticipate that the level of the equity-based S&P 500^® Index (the “Index”) will decrease from the Starting Value of the Index, determined on the Pricing Date, to the Ending Value of the Index, determined on the Calculation Days shortly prior to the maturity date of the Notes, or (ii) who want to invest in such a security for risk diversification purposes. Investors must be willing to forego interest payments on the Notes and willing to accept a repayment that is capped and that may be less, and potentially significantly less, than the Original Public Offering Price of the Notes if the Index increases.

Hypothetical Payout Profile

This graph reflects the hypothetical returns on the Notes, assuming a Capped Value of 22.0%, the midpoint of the range of 20.0% and 24.0%. The green line reflects the hypothetical returns on the Notes, while the blue dashed-line reflects the hypothetical return of a direct investment in the stocks included in the Index, excluding dividends.   This graph has been prepared for purposes of illustration only. Your actual return will depend on the actual Starting Value, Ending Value, Capped Value and the term of your investment.

Hypothetical Payments at Maturity

Examples

Set forth below are four examples of payment at maturity calculations (rounded to two decimal places), assuming a hypothetical Starting Value of 930.09, the closing level of the Index on October 29, 2008, and a Capped Value of $12.20, the midpoint of the range of $12.00 and $12.40.

Example 1—The hypothetical Ending Value is 130% of the hypothetical Starting Value and more than the hypothetical Threshold Value:

Hypothetical Starting Value: 930.09

Hypothetical Ending Value:  1,209.12

Hypothetical Threshold Value:  1,023.10

$10 –	(	$10 ×	(	1,209.12 – 1,023.10	))	= $8.00
				930.09

Payment at maturity (per unit) = $8.00

Example 2—The hypothetical Ending Value is 105% of the hypothetical Starting Value but less than the hypothetical Threshold Value:

Hypothetical Starting Value: 930.09

Hypothetical Ending Value:  976.59

Hypothetical Threshold Value:  1,023.10

Payment at maturity (per unit) = $10.00

Example 3—The hypothetical Ending Value is 98% of the hypothetical Starting Value:

Hypothetical Starting Value: 930.09

Hypothetical Ending Value:  911.49

$10 +	(	$50 ×	(	930.09 – 911.49	))	= $11.00
				930.09

Payment at maturity (per unit) = $11.00

Example 4—The hypothetical Ending Value is 70% of the hypothetical Starting Value:

Hypothetical Starting Value: 930.09

Hypothetical Ending Value:  651.06

$10 +	(	$50 ×	(	930.09 – 651.06	))	= $25.00
				930.09

Payment at maturity (per unit) = $12.20         (Payment at maturity cannot be greater than the Capped Value)

TS-3

The following table illustrates, for a hypothetical Starting Value of 930.09 (the closing level of the Index on October 29, 2008) and a range of hypothetical Ending Values of the Index:

§ the percentage change from the hypothetical Starting Value to the hypothetical Ending Value;

§ the total amount payable on the maturity date per unit (rounded to two decimal places);

§ the total rate of return to holders of the Notes;

§ the pretax annualized rate of return to holders of the Notes; and

§ the pretax annualized rate of return of an investment in the stocks included in the Index, which includes an assumed aggregate dividend yield of 3.26% per annum, as more fully described below.

The table below assumes a Capped Value of $12.20, the midpoint of the range of $12.00 and $12.40.

(1) The annualized rates of return specified in this column are calculated on a semiannual bond equivalent basis and assume an investment term from November 3, 2008 through January 4, 2010, a term expected to be approximately equal to that of the Notes.

(2) This rate of return assumes:

(a) a percentage change in the aggregate price of the stocks included in the Index that equals the percentage change in the level of the Index from the hypothetical Starting Value to the relevant hypothetical Ending Value;

(b) a constant dividend yield of 3.26% per annum, paid quarterly from the date of initial delivery of the Notes, applied to the level of the Index at the end of each quarter assuming this value increases or decreases linearly from the hypothetical Starting Value to the applicable hypothetical Ending Value; and

(c) no transaction fees or expenses.

(3) The total amount payable on the maturity date per unit of the Notes cannot exceed the assumed Capped Value of $12.20 (the midpoint of the range of $12.00 and $12.40).

(4) This is the hypothetical Starting Value, the closing level of the Index on October 29, 2008. The actual Starting Value will be determined on the Pricing Date and will be set forth in the final term sheet made available in connection with sales of the Notes.

(5) This represents the hypothetical Threshold Value, rounded to two decimal places. Investors will receive $10 per unit if the Ending Value is greater than or equal to the Starting Value but less than or equal to the hypothetical Threshold Value. The actual Threshold Value will be determined on the Pricing Date and will be set forth in the final term sheet made available in connection with sales of the Notes.

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

Risk Factors

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.

§ Your investment may result in a loss.

§ Your yield may be lower than the yield on other debt securities of comparable maturity.

§ You must rely on your own evaluations regarding the merits of an investment linked to the Index.

§ Any positive return is limited by the Capped Value.

§ You will not have the right to receive cash dividends or exercise ownership rights with respect to the stocks included in the Index.

§ 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 publisher of the Index may adjust the Index in a way that affects its level, and the publisher has no obligation to consider your interests.

§ 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.

§ Purchases and sales of securities underlying the Index by us and our affiliates may affect your return.

§ Potential conflicts of interest could arise.

§ Tax consequences are uncertain. See “Certain U.S. Federal Income Taxation Considerations” below.

In addition to the risk factors, it is important to bear in mind that the Notes are senior debt securities of ML&Co. and are not guaranteed or insured by the FDIC or secured by collateral. The Notes will rank equally with all of our other unsecured and unsubordinated debt, and any payments due on the Notes, including any repayment of principal, will be subject to the credit risk of ML&Co.

Recent Developments

On September 15, 2008, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Bank of America Corporation (“Bank of America”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, a wholly owned subsidiary of Bank of America will merge with and into ML&Co. with ML&Co. continuing as the surviving corporation and as a wholly owned subsidiary of Bank of America. The merger has been approved by the board of directors of each of ML&Co. and Bank of America and is subject to shareholder votes at both companies.

Upon completion of the merger, each outstanding share of ML&Co. common stock will be converted into the right to receive 0.8595 shares of Bank of America common stock, and the Bank of America board of directors will be expanded to include three existing directors of ML&Co. The Merger Agreement contains certain termination rights for both ML&Co. and Bank of America. The transaction is expected to close on or after December 31, 2008, subject to shareholder approval and customary closing conditions, including standard regulatory approvals.

Investor Considerations

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

§ You anticipate that the Index will depreciate moderately from the Starting Value to the Ending Value or seek risk diversification.

§ You accept that your investment may result in a loss, which could be significant, if the level of the Index increases 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 or remain listed on NYSE Arca. You understand that any listing does not ensure that a trading market will develop for the Notes or that there will be liquidity in any trading market. You understand that secondary market prices for the Notes, if any, will be affected by various factors, including the perceived creditworthiness of ML&Co.

The Notes may not be appropriate investments for you if:

§ You anticipate that the Index will appreciate from the Starting Value to the Ending Value or that the Index will not depreciate 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 20.0% and 24.0%.

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

§ You want to receive dividends 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.

TS-5

Other Provisions

We may deliver the Notes against payment therefor in New York, New York on a date that is in excess of 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.

The following definition replaces the definition of “Market Measure Business Day” set forth in product supplement ARNB-4: A “Market Measure Business Day” means a day on which (1) the New York Stock Exchange and the Nasdaq Stock Market (or any successor to the foregoing exchanges) are open for trading and (2) the Market Measure or any successor thereto is calculated and published.

Supplement to the Plan of Distribution

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 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.

The Index

The S&P 500 Index

All disclosure contained in this term sheet 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, a division of The McGraw-Hill Companies, Inc. (“Standard & Poor’s” or “S&P”). 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 S&P 500 Index or any successor index.

Standard & Poor’s publishes the S&P 500 Index. The S&P 500 Index is maintained by the S&P Index Committee, a team of Standard & Poor’s economists and index analysts, who meet on a regular basis. The goal of the S&P Index Committee is to ensure that the S&P 500 Index remains a leading indicator of U.S. equities, reflecting the risk and return characteristics of the broader large market capitalization segment of the market on an on-going basis. The S&P Index Committee also monitors constituent liquidity to ensure efficient portfolio trading while keeping index turnover to a minimum.

The calculation of the level of the S&P 500 Index, discussed below in 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. Ten main groups of companies comprise the S&P 500 Index: 1) Consumer Discretionary; 2) Consumer Staples; 3) Energy; 4) Financials; 5) Health Care; 6) Industrials; 7) Information Technology; 8) Materials; 9) Telecommunication Services; and 10) 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. Relevant criteria for index additions include:

•      U.S. Company. Determining factors include location of the company’s operations, its corporate structure, its accounting standards and its exchange listings;

•      Market Capitalization. Companies with market capitalization in excess of US$4 billion. This minimum is reviewed from time to time to ensure consistency with market conditions;

•      Public Float. There must be public float of at least 50%;

•      Financial Viability. Companies should have four consecutive quarters of positive as-reported earnings, where as-reported earnings are defined as GAAP Net Income excluding discontinued operations and extraordinary items;

•      Adequate Liquidity and Reasonable Price. The ratio of annual dollar value traded to market capitalization for the company should be 0.30 or greater. Very low stock prices can affect a stock’s liquidity;

•      Sector Representation. Companies’ industry classifications contribute to the maintenance of a sector balance that is in line with the sector composition of the universe of eligible companies with market capitalization in excess of US$4 billion; and

•      Company Type. Constituents must be operating companies. Closed-end funds, holding companies, partnerships, investment vehicles and royalty trusts are not eligible. Real Estate Investment Trusts (REITs) (excluding mortgage REITs) and business development companies (BDCs) are eligible for inclusion.

Continued index membership is not necessarily subject to these guidelines. The S&P Index Committee aims to minimize unnecessary turnover in index membership and each removal is determined on a case-by-case basis. Relevant criteria for index removals include:

•      Companies that substantially violate one or more of the criteria for index inclusion; and

•      Companies involved in merger, acquisition, or significant restructuring such that they no longer meet the inclusion criteria.

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 Standard & Poor’s currently employs the following methodology to calculate the S&P 500 Index, no assurance can be given that Standard & Poor’s will not modify or change this methodology in a manner that may affect the amount an investor receives on the maturity date of the Notes.

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, Standard & Poor’s 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. Standard & Poor’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).

The goal of float adjustment is to distinguish strategic shareholders, whose holdings depend on concerns such as maintaining control rather than the economic fortunes of the company, from those holders whose investments depend on the stock’s price and their evaluation of the company’s future prospects. Shareholders concerned with control of a company include board members, founders and owners of large blocks of stock. Likewise, holdings of stock in one corporation by another corporation are normally for control, not investment, purposes. Normally government holdings are not investments made because a stock is expected to appreciate or the government entity is managing its excess funds through equity investments.

TS-7

Share owners acting as investors will consider changes in the stock’s price, earnings or the company’s operations as possible reasons to buy or sell the stock. They hold the stock because they expect it to appreciate in value and believe the stock offers better risk and return opportunities than other investments. Further, a sharp rise or fall in the stock’s price could be a reason to adjust their positions. Mutual funds, pension plans and other institutional investors are usually in this category. The fact that an institutional investor has held a block of shares for several years is not evidence that the block is being held for control, rather than investment, reasons.

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 presumed to be for control and are subject to float adjustment:

•      holdings by other publicly traded corporations, venture capital firms, private equity firms, strategic partners, or leveraged buy-out groups;

•      holdings by government entities, including all levels of government in the United States or foreign countries; and

•      holdings by current or former officers and directors of the company, founders of the company, or family trusts of officers, directors, or founders, as well as holdings of trusts, foundations, pension funds, employee stock ownership plans, or other investment vehicles associated with and controlled by the company.

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 listed above 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 “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

The S&P Index Committee follows a set of published guidelines for maintaining the index. These guidelines provide the transparency required and fairness needed to enable investors to replicate the index and achieve the same performance as the S&P 500 Index.

In order to ensure that the level of the S&P 500 Index remains an accurate barometer of stock market performance over time, it is necessary to adjust the index divisor in response to any change that alters the total market value of the index while holding stock prices constant. Index maintenance—reflecting changes in shares outstanding, capital actions, addition or deletion of stocks to the S&P 500 Index—should not change the level of the index. If the S&P 500 Index closes at 1,250 and one stock is replaced by another, after the market close, the index should open at 1,250 the next morning if all of the opening prices are the same as the previous day’s closing prices. This is accomplished with an adjustment to the divisor.

Divisor adjustments are made “after the close” meaning that after the close of trading the closing prices are used to calculate the new divisor based on whatever changes are being made. It is, then, possible to provide two complete descriptions of the index—one as it existed at the close of trading and one as it will exist at the next opening of trading. If the same stock prices are used to calculate the index levels for these two descriptions, the index levels will be the same.

For cataloging changes, it is useful to separate changes caused by the management of the index from those stemming from corporate actions of the constituent companies. Among those changes driven by index management are adding or deleting companies, adjusting share counts and changes to IWFs and other factors affecting share counts or stock prices.

Index Management Related Changes. When a company is added to or deleted from the S&P 500 Index, the net change in the market value of the index is calculated and this is used to calculate the new divisor. The market values of stocks being added or deleted are based on the prices, shares outstanding, IWFs and any other share count adjustments. Specifically, if a company being added has a total market cap of US$10 billion, an IWF of 85% and, therefore, a float adjusted market cap of US$8.5 billion, the market value for the added company used is US$8.5 billion.

For most S&P indices, there are a few dates during the year when IWFs and share counts are updated. (Typically small changes in shares outstanding are reflected in indices once a quarter to avoid excessive changes to an index.) The revisions to the divisor resulting from these are calculated and a new divisor is determined.

Corporate Action Related Changes. There are a large range of different corporate actions ranging from routine share issuances or buy backs to unusual events like spin-offs or mergers. These are listed on the table below with notes about the necessary changes and whether the divisor is adjusted.

TS-8

Corporate Action	Comments	Divisor Adjustment
Company added/deleted	Net change in market value determines the divisor adjustment.	Yes
Change in shares outstanding	Any combination of secondary issuance, share repurchase or buy back—share counts revised to reflect change.	Yes
Stock split	Share count revised to reflect new count. Divisor adjustment is not required since the share count and price changes are offsetting.	No
Spin-off	If the spun-off company is not being added to the index, the divisor adjustment reflects the decline in index market value (i.e., the value of the spun-off unit).	Yes
Spin-off	Spun-off company added to the index, no company removed from the index.	No
Spin-off	Spun-off company added to the index, another company removed to keep number of names fixed. Divisor adjustment reflects deletion.	Yes
Change in IWF	Increasing (decreasing) the IWF increases (decreases) the total market value of the index. The divisor change reflects the change in market value caused by the change to an IWF.	Yes
Special Dividend	When a company pays a special dividend the share price is assumed to drop by the amount of the dividend; the divisor adjustment reflects this drop in index market value.	Yes
Rights offering	Each shareholder receives the right to buy a proportional number of additional shares at a set (often discounted) price. The calculation assumes that the offering is fully subscribed. Divisor adjustment reflects increase in market cap measured as the shares issued multiplied by the price paid.	Yes

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 participations or other recapitalizations) are made weekly and are announced on Tuesdays 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 S&P 500 Index is intended to provide an indication of the pattern of common stock price movement in the United States. The calculation of the level of the S&P 500 Index, discussed below in 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. As of September 30, 2008, 420 companies or 84.0% of the market capitalization of the S&P 500 Index traded on the New York Stock Exchange; 79 companies or 16.0% of the market capitalization of the S&P 500 Index traded on The Nasdaq Stock Market; and no companies traded on the American Stock Exchange. As of September 30, 2008, the aggregate market value of the companies included in the S&P 500 Index represented approximately 75% of the aggregate market value of stocks included in the Standard & Poor’s Stock Guide Database of domestic common stocks traded in the U.S., excluding American depositary receipts, limited partnerships and mutual funds. Standard & Poor’s chooses companies for inclusion in the S&P 500 Index with the aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the Standard & Poor’s Stock Guide Database, which Standard & Poor’s uses as an assumed model for the composition of the total market. 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, with the approximate percentage of the market capitalization of the S&P 500 Index included in each group as of September 30, 2008 indicated in parentheses: Consumer Discretionary (8.5%); Consumer Staples (12.2%); Energy (13.4%); Financials (15.8%); Health Care (13.1%); Industrials (11.1%); Information Technology (16.0%); Materials (3.4%); Telecommunication Services (3.0%) and Utilities (3.6%). 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 following graph sets forth the monthly historical performance of the S&P 500 Index in the period from January 2003 through September 2008. This historical data on the S&P 500 Index is not necessarily indicative of the future performance of the S&P 500 Index or what the value of the Notes may be. Any historical upward or downward trend in the level of the S&P 500 Index during any period set forth below is not an indication that the S&P 500 Index is more or less likely to increase or decrease at any time over the term of the Notes. On October 29, 2008, the closing level of the S&P 500 Index was 930.09.

Standard & Poor’s and MLPF&S have entered into or, to the extent required, will enter into a non-exclusive license agreement providing for the license to MLPF&S, in exchange for a fee, of the right to use indices owned and published by Standard & Poor’s in connection with some securities, including the Notes, and ML&Co. is an authorized sublicensee of MLPF&S. The license agreement between Standard & Poor’s and MLPF&S provides that the following language must be stated in this term sheet:

“The Notes are not sponsored, endorsed, sold or promoted by S&P. S&P makes no representation or warranty, express or implied, to the holders of the Notes or any member of the public regarding the advisability of investing in securities generally or in the Notes particularly or the ability of the S&P 500 Index to track general stock market performance. S&P’s only relationship to MLPF&S (other than transactions entered into in the ordinary course of business) is the licensing of certain service marks and trade names of S&P and of the S&P 500 Index which is determined, composed and calculated by S&P without regard to ML&Co. or the Notes. S&P has no obligation to take the needs of ML&Co. or the holders of the Notes into consideration in determining, composing or calculating the S&P 500 Index. S&P is not responsible for and has not participated in the determination of the timing of the sale of the Notes, prices at which the Notes are to initially be sold, or quantities of the Notes to be issued or in the determination or calculation of the equation by which the Notes are to be converted into cash. S&P has no obligation or liability in connection with the administration, marketing or trading of the Notes.”

Summary Tax Consequences

You should consider the U.S. federal income tax consequences of an investment in the Notes, including the following:

• 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 the Notes for all tax purposes as pre-paid cash-settled financial contracts linked to the level of the Index.

• Under this characterization and tax treatment of the Notes, upon receipt of cash on the maturity date, you will recognize gain or loss. Although it is uncertain whether any such gain or loss should be treated as capital or ordinary, absent a future clarification in law to the contrary, ML&Co. intends to report such gain or loss as capital gain or loss, which will be long-term capital gain or loss if you held your Note for more than one year as of the maturity date.

• Under this characterization and tax treatment of the Notes, you will generally recognize capital gain or loss to the extent that you receive cash upon a sale or exchange of a Note prior to the maturity date, which will be short-term or long-term capital gain or loss depending on your holding period for the Notes as of the date of sale or exchange.

Certain U.S. Federal Income Taxation Considerations

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 ARNB-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 U.S. federal income tax purposes, of the Notes or securities with terms substantially the same as the Notes. Accordingly, the proper U.S. 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 cash-settled financial 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 U.S. 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 U.S. 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 cash-settled financial 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 ARNB-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. The deductibility of capital losses is subject to certain limitations.

Sale or Exchange of the Notes.    Assuming that the Notes are properly characterized and treated as cash-settled financial 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. The deductibility of capital losses is subject to certain limitations.

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 (but not identical) 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, and whether the tax treatment of such instruments should vary depending upon the nature of the underlying asset. 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 ARNB-4.

Experts

The consolidated financial statements incorporated by reference in this term sheet from Merrill Lynch & Co., Inc.’s Annual Report on Form 10-K for the year ended December 28, 2007 and the effectiveness of Merrill Lynch & Co., Inc. and subsidiaries’ internal control over financial reporting have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports, incorporated herein by reference (which reports (1) expressed an unqualified opinion on the consolidated financial statements and included an explanatory paragraph regarding the changes in accounting methods in 2007 relating to 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 in 2006 for share-based payments to conform to Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment,” and included an explanatory paragraph relating to the restatement discussed in Note 20 to the consolidated financial statements and (2) expressed an unqualified opinion on the effectiveness of internal control over financial reporting). Such consolidated financial statements 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 28, 2008 and March 30, 2007 and the three-month and six-month periods ended June 27, 2008 and June 29, 2007, 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 included in Merrill Lynch & Co., Inc.’s Quarterly Reports on Form 10-Q for the quarters ended March 28, 2008 (which report included an explanatory paragraph relating to the restatement discussed in Note 16 to the condensed consolidated interim financial statements), and June 27, 2008 (which report included explanatory paragraphs related to the restatement discussed in Note 16 to the condensed consolidated interim financial statements and a number of transactions subsequent to the balance sheet date which are expected to have a material impact on the interim financial statements for the three and nine month periods ended September 26, 2008 discussed in Note 18 to the condensed consolidated interim financial statements), 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 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.

Structured Investments Classification

ML&Co. classifies certain of its structured investments (the “Structured Investments”), including the Notes, into four categories, each with different investment characteristics. The description below is intended to briefly describe the four categories of Structured Investments offered: Principal Protection, Enhanced Income, Market Participation and Enhanced Participation. A Structured Investment may, however, combine characteristics that are relevant to one or more of the other categories. As such, a category should not be relied upon as a description of any particular Structured Investment.

Principal Protection: Principal Protected Structured Investments offer full or partial principal protection at maturity, while offering market exposure and the opportunity for a better return than may be available from comparable fixed income securities. Principal protection may not be achieved if the investment is sold prior to maturity.

Enhanced Income: Structured Investments offering enhanced income may offer an enhanced income stream through interim fixed or variable coupon payments. However, in exchange for receiving current income, investors may forfeit upside potential on the underlying asset. These investments generally do not include the principal protection feature.

Market Participation: Market Participation Structured Investments can offer investors exposure to specific market sectors, asset classes and/or strategies that may not be readily available through traditional investment alternatives. Returns obtained from these investments are tied to the performance of the underlying asset. As such, subject to certain fees, the returns will generally reflect any increases or decreases in the value of such assets. These investments are not structured to include the principal protection feature.

Enhanced Participation: Enhanced Participation Structured Investments may offer investors the potential to receive better than market returns on the performance of the underlying asset. Some structures may offer leverage in exchange for a capped or limited upside potential and also in exchange for downside risk. These investments are not structured to include the principal protection feature.

The classification of Structured Investments is meant solely for informational purposes and is not intended to fully describe any particular Structured Investment nor guarantee any particular performance.
