QUANTUMONLINE.COM SECURITY DESCRIPTION:  Merrill Lynch & Co. Inc., Accelerated Return Bear Market Notes linked to the PHLX Housing Sector Index, due 9/5/2008, and issued at $10 per note. These notes are designed for investors who believe that the PHLX Housing Sector Index will decline over the period of the notes. The notes will receive no payments before maturity, are not redeemable prior to maturity, and make no guarantee of the return of principal at maturity. At maturity the holder will receive a payment based on the percentage change in the PHLX Housing Sector Index, starting value 213.92 as of 6/27/2007. If the Index has decreased, the maturity payment will be based on triple the percentage decrease in the index, not to exceed $13.21 per note. If the index has increased but has not exceeded the threshold value of 235.21, the holder will receive $10 per note. If the index has increased above the threshold value, the holder will receive a maturity payment that is $10 minus $10 times the Ending Value minus the Threshold Value divided by the Starting Value of the index. As a result, the maturity payment may be less, and possibly significantly less, than the $10 offering price but will not be less than $0 per note. See page TS-2 of the prospectus for further details on the maturity payment, page TS-3 for hypothetical examples of the maturity payment, and page TS-7 for a discussion of the tax considerations of the notes. The notes are senior unsecured debt securities issued by Merrill Lynch & Co. Inc. and rank equally with all of their other unsecured and unsubordinated debt.
