Summary Terms

 

The Notes:

 

·       The Notes are designed for investors who are seeking exposure to the Nikkei 225 Index (Index symbol “NKY”) (the “Index”), who anticipate that the level of the Index will increase from the starting value of the Index on the pricing date to the ending value of the Index determined on the valuation dates shortly before the maturity date of the Notes. Investors must be willing to forego interest payments on the Notes and willing to accept a return that may be less than the principal amount of their Notes and that will not exceed the limit described in the attached offering document.

 

·       There will be no payments on the Notes prior to the maturity date and we cannot redeem the Notes prior to the maturity date.

 

·       There is no principal protection on these Notes and therefore an investor will not receive a minimum fixed amount on the Notes at maturity and the return on the Notes is capped.

 

·       The Notes are made available to each investor outside of the United States in a minimum initial investment of US$50,000 (US$75,000 for residents of the European Economic Area), and subject to any other restrictions, as may be applicable to an investor under the private offering rules of any jurisdiction outside of the United States.

 

·       We have applied to have the Notes listed on the American Stock Exchange under the trading symbol “NKB”. If approval of this application is granted, the Notes will be listed on the American Stock Exchange at the time of such approval. We make no representation, however, that the Notes will be listed, or, if listed, will remain listed for the entire term of the Notes.

   

 

 

·       The Notes will be senior unsecured debt securities of Merrill Lynch & Co., Inc., and part of a series entitled “Medium-Term Notes, Series C”. The Notes will have the CUSIP No.:            .

 

·       The settlement date for the Notes is expected to be August     , 2007.

 

Payment on the maturity date:

 

•      The amount an investor receives on the maturity date will be based upon the direction of and percentage change from the starting value to the ending value of the Index. If the level of the Index:

 

•     has increased, on the maturity date an investor will receive a payment per unit equal to $10.00 plus an amount equal to $10.00 multiplied by triple the percentage increase of the Index, up to a maximum total payment which will be between $12.70 and $13.10 per unit, as described in the attached offering document.

 

•     has decreased or is unchanged, on the maturity date an investor will receive a payment per unit based upon any percentage decrease and, as a result, an investor may receive less, and possibly significantly less, than the $10.00 original public offering price per unit.

 

•     The actual maximum payment on the Notes will be determined on the pricing date and set forth in the final offering document made available in connection with sales of the Notes.
