Summary

The MITTS Securities Linked to an International Equity Index Basket due                     , 2011 (the “MITTS Securities”) are senior, unsecured debt securities of Merrill Lynch & Co., Inc. that provide investors with a 105% participation rate in increases in the value of an International Equity Index Basket (the “Basket”) from the Starting Value of the Basket on the Pricing Date, to the Ending Value of the Basket to be determined on the valuation dates shortly prior to the Maturity Date of the MITTS Securities. Investors must be willing to forego interest payments on the MITTS Securities.

The Basket is comprised of the Dow Jones EURO STOXX 50 Index and the Nikkei 225 Index (each a “Basket Component Index” and together the “Basket Component Indices”). Each Basket Component Index will be assigned a weighting so that each Basket Component Index will contribute equally to the value of the Basket on the Pricing Date.

Hypothetical Payout Profile

		This graph reflects the hypothetical returns on the MITTS Securities. The orange line reflects the hypothetical returns on the MITTS Securities, while the blue dashed line reflects the return of a direct investment in the Basket, excluding dividends.   This graph has been prepared for purposes of illustration only. Your actual return will depend on the actual Ending Value and the term of your investment.

Hypothetical Payments at Maturity

Examples

Set forth below are two examples of Supplemental Redemption Amount calculations including a Participation Rate equal to 105%:

Example 1—The hypothetical Ending Value is 10% lower than the Starting Value:

Example 2—The hypothetical Ending Value is 30% greater than the Starting Value:

Payment at maturity (per unit) = $10 + $3.15 = $13.15

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

        This table includes a Participation Rate of 105% and assumes a term of 3.67 years, the midpoint of the range of 3.42 to 3.92 years.

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

Risk Factors

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

Investor Considerations

Other Provisions

We may deliver the MITTS Securities 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 MITTS Securities occurs more than three business days from the Pricing Date, purchasers who wish to trade MITTS Securities 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 Basket

The Basket is designed to allow investors to participate in the percentage changes in the levels of the Basket Component Indices from the Starting Value to the Ending Value of the MITTS Securities. The Basket Component Indices are described in the section below. Each Basket Component Index will be assigned an equal weighting so that each Basket Component Index represents an equal portion of the value of the Basket on the Pricing Date.

The respective publishers of the Basket Component Indices have no obligations relating to the MITTS Securities or amounts to be paid to you, including any obligation to take the needs of Merrill Lynch & Co., Inc. or of holders of the MITTS Securities into consideration for any reason. These respective publishers will not receive any of the proceeds of the offering of the MITTS Securities and are not responsible for, and have not participated in, the offering of the MITTS Securities and are not responsible for, and will not participate in, the determination or calculation of the amount receivable by holders of the MITTS Securities. All disclosure contained in this term sheet regarding any Basket Component Index, including with limitation, its make-up, method of calculation and changes in components has been derived from publicly available information prepared by the distributor of the Basket Component Index. Neither Merrill Lynch & Co., Inc. nor MLPF&S have independently verified the accuracy or completeness of that information.

For more information on the Basket, please see the section entitled “The Basket” in the product supplement MITTS-1.

If July 19, 2007 were the Pricing Date, for each Basket Component Index, the closing level and hypothetical Multiplier would be as follows:

While historical information on the Basket will not exist before the Pricing Date, the following graph sets forth the hypothetical historical performance of the Basket in the period from January 2002 through June 2007, based upon historical levels of each Basket Component Index, the hypothetical Multipliers and a Basket value calculated as of 100 on July 19, 2007. This hypothetical historical data on the Basket is not necessarily indicative of the future performance of the Basket or what the value of the MITTS Securities may be. Any historical upward or downward trend in the value of the Basket during any period set forth below is not an indication that the Basket is more or less likely to increase or decrease at any time over the term of the MITTS Securities.

		The information on the Basket provided in this document should be read together with the discussion under the heading “The Market Measure— Baskets” beginning on page PS-15 of the product supplement MITTS-1.

The Basket Component Indices

The Dow Jones EURO STOXX 50^SM Index

The Dow Jones EURO STOXX 50 Index was created by STOXX Limited., a joint venture founded by SWX Group, Deutsche Börse AG and Dow Jones. Publication of the Dow Jones EURO STOXX 50 Index began on February 28, 1998, based on an initial level of the Dow Jones EURO STOXX 50 Index of 1,000 at December 31, 1991. The Dow Jones EURO STOXX 50 Index was created to reflect the market-capitalization weighted performance of large companies from the major industry groupings in Austria, Belgium, Finland, France, Germany, Greece, Ireland, Italy, the Netherlands, Portugal and Spain. The companies included in the Dow Jones EURO STOXX 50 Index account for approximately 60% of the free-float market capitalization of the Dow Jones EURO STOXX Total Market Index, which in turn accounts for approximately 95% of the free-float market capitalization of the countries with companies eligible for inclusion in the Dow Jones EURO STOXX 50 Index. For more information on the Dow Jones EURO STOXX 50 Index, please see the section entitled “Dow Jones EURO STOXX 50 Index” in the index supplement I-1.

The following graph sets forth the historical performance of the Dow Jones EURO STOXX 50 Index in the period from January 2002 through June 2007.

Any historical upward or downward trend in the level of the Dow Jones EURO STOXX 50 Index during any period set forth below is not an indication that the Dow Jones EURO STOXX 50 Index is more or less likely to increase or decrease at any time over the term of the MITTS Securities. On July 19, 2007, the closing level of the Dow Jones EURO STOXX 50 Index was 4,522.64.

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 MITTS Securities. 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 MITTS-1 and MTN prospectus supplement, which you should carefully review prior to investing in the MITTS Securities. Capitalized terms used and not defined herein have the meanings ascribed to them in the accompanying product supplement MITTS-1.

General. There are no statutory provisions, regulations, published rulings or judicial decisions addressing or involving the characterization, for United States federal income tax purposes, of the MITTS Securities or securities with terms substantially the same as the MITTS Securities. However, although the matter is not free from doubt, under current law, each MITTS Security should be treated as a debt instrument of ML&Co. for United States federal income tax purposes. ML&Co. currently intends to treat each MITTS Security as a debt instrument of ML&Co. for United States federal income tax purposes and, where required, intends to file information returns with the Internal Revenue Service (the “IRS”) in accordance with this treatment, in the absence of any change or clarification in the law, by regulation or otherwise, requiring a different characterization of the MITTS Securities. Prospective investors in the MITTS Securities should be aware, however, that the IRS is not bound by ML&Co.’s characterization of the MITTS Securities as indebtedness, and the IRS could possibly take a different position as to the proper characterization of the MITTS Securities for United States federal income tax purposes. Accordingly, prospective purchasers are urged to consult their own tax advisors regarding the tax consequences of investing in the MITTS Securities. The following summary assumes that the MITTS Securities will be treated as debt instruments of ML&Co. for United States federal income tax purposes.

Interest Accruals. Each year, a U.S. Holder will be required to pay taxes on ordinary income from the MITTS Securities over their term based upon an estimated yield for the MITTS Securities, even though such U.S. Holder will not receive any payments until the maturity date. We will have determined this estimated yield, in accordance with the CPDI Regulations, solely in order for a U.S. Holder to calculate the amount of taxes that such U.S. Holder will owe each year as a result of owning a MITTS Security. This estimated yield will not be either a prediction or a guarantee of what the actual Supplemental Redemption Amount will be, or that the actual Supplemental Redemption Amount will even exceed zero.

Sale or Exchange of the MITTS Securities. Upon the sale or exchange of a MITTS Security prior to the maturity date, a U.S. Holder will be required to recognize taxable gain or loss in an amount equal to the difference, if any, between the amount realized by the U.S. Holder upon such sale or exchange and the U.S. Holder’s adjusted tax basis in the MITTS Security as of the date of disposition. A U.S. Holder’s adjusted tax basis in a MITTS Security generally will equal the U.S. Holder’s initial investment in the MITTS Security increased by any interest previously included in income with respect to the MITTS Security by the U.S. Holder. Any taxable gain will be treated as ordinary income. Any taxable loss will be treated as ordinary loss to the extent of the U.S. Holder’s total interest inclusions on the MITTS Security. Any remaining loss generally will be treated as long-term or short-term capital loss (depending upon the U.S. Holder’s holding period for the MITTS Security). In addition, U.S. Holders purchasing a MITTS Security at a price that differs from the adjusted issue price of the MITTS Security as of the purchase date (e.g., subsequent purchasers) may be subject to rules providing for certain adjustments to the foregoing rules and these U.S. Holders should consult their own tax advisors concerning these rules.

Hypothetical Table. The following table sets forth the amount of interest that would be deemed to have accrued with respect to each MITTS Security during each accrual period over an assumed term of forty four months for the MITTS Securities based upon a hypothetical projected payment schedule for the MITTS Securities (including both a hypothetical Projected Supplemental Redemption Amount and a hypothetical estimated yield equal to 5.27% per annum (compounded semi-annually)) as determined by ML&Co. for purposes of illustrating the application of the CPDI Regulations to the MITTS Securities as if the MITTS Securities had been issued on July 25, 2007 and were scheduled to mature on March 25, 2011. The following table is for illustrative purposes only. The actual projected payment schedule for the MITTS Securities (including both the actual Projected Supplemental Redemption Amount and the actual estimated yield) will be determined by ML&Co. on the Pricing Date and will depend upon actual market interest rates (and thus ML&Co.’s borrowing costs for debt instruments with comparable maturities) as of that date. The actual projected payment schedule for the MITTS Securities (including both the actual Projected Supplemental Redemption Amount and the actual estimated yield) and the actual tax accrual table will be set forth in the final Term Sheet delivered to investors in connection with the initial sale of the MITTS Securities.

Hypothetical Projected Supplemental Redemption Amount = $2.314 per Unit of the MITTS Securities.

Prospective purchasers of the MITTS Securities 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 MITTS Securities. See the discussion under the heading “United States Federal Income Taxation” in the accompanying product supplement MITTS-1.

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 Merrill Lynch & Co., Inc.’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) expressed an unqualified opinion on the consolidated financial statements and 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) expressed an unqualified opinion on management’s assessment regarding the effectiveness of internal control over financial reporting, and (3) expressed 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 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 report included in the Company’s Quarterly Reports on Form 10-Q for the quarter ended March 30, 2007 (which report included 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.
