Summary

The Accelerated Return Notes^SM Linked to the S&P MidCap 400^® Index due January     , 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 S&P MidCap 400 Index (the “Index”) increases moderately from the Starting Value of the Index on the Pricing Date to the Ending Value of the Index determined on valuation dates 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 repayment that may be less, and potentially significantly less, than the original public offering price of the Notes.

Terms of the Notes		Determining Payment at Maturity for the Notes

Hypothetical Payout Profile

		This table reflects the hypothetical returns on the Notes, assuming a Capped Value of 16%, the midpoint of the range of 14% and 18%. The orange line reflects the hypothetical returns on the Notes, while the blue line reflects the return of an investment in the Index.   This table has been prepared for purposes of illustration only. Your actual return will depend on the actual Ending Value, Capped Value and the term of your investment.

Hypothetical Payments at Maturity

Examples

Set forth below are three examples of payment at maturity calculations, assuming a hypothetical Starting Value of 881.12, the level of the Index on September 26, 2007, and a Capped Value of $11.60, the midpoint of the range of $11.40 and $11.80.

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

Hypothetical Starting Value: 881.12

Hypothetical Ending Value: 704.90

Payment at maturity (per unit) = $8.00

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

Hypothetical Starting Value: 881.12

Hypothetical Ending Value: 907.55

Payment at maturity (per unit) = $10.90

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

Hypothetical Starting Value: 881.12

Hypothetical Ending Value: 1,057.34

Payment at maturity (per unit) = $11.60         (Payment at maturity cannot be greater than the Capped Value)

The following table illustrates, for a hypothetical Starting Value of 881.12 (the closing value of the Index on September 26, 2007) and a range of hypothetical Ending Values of the Index:

The table below assumes a Capped Value of $11.60, the midpoint of the range of $11.40 and $11.80.

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.

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.

Investor Considerations

Other Provisions

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.

The Index

The S&P MidCap^® Index

The Index is published by Standard & Poor’s. The Index is intended to measure the performance of the common stock of mid-sized U.S. companies with a market capitalization of between approximately $1.5 billion and $5.5 billion. The calculation of the level of the Index is based on the relative value of the aggregate market value of the common stocks of 400 companies as of a particular time compared to the aggregate average market value of the common stocks of 400 similar companies on the base date of June 28, 1991. Standard & Poor’s chooses companies for inclusion in the 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 U.S. mid-cap equity 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. Standard & Poor’s may from time to time, in its sole discretion, add companies to, or delete companies from, the Index to achieve the objectives stated above. For more information on the Index, please see the section entitled “The S&P MidCap Index” in the index supplement I-1.

The following graph sets forth the historical performance of the Index in the period from January 2002 through August 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 September 26, 2007, the closing level of the Index was 881.12.

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 to the discussion under the section entitled “United States Federal Income Taxation” in the accompanying product supplement ARN-3 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-3) 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 Notes 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 Notes as of the date of such sale or exchange.

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.

Experts

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