QUANTUMONLINE.COM SECURITY DESCRIPTION:  Merrill Lynch & Co. Inc., Accelerated Return Bear Market Notes linked to the Russell 3000 Index, due 11/7/2008, and issued at $10 per unit. These notes are designed for investors who believe that the Russell 3000 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 Russell 3000 Index, starting value 846.32 as of 8/29/2007. If the Index has decreased, the maturity payment will be based on three times the percentage decrease in the Index, not to exceed $12.649 per unit. If the Index has increased, the holder will receive a maturity payment that is reduced from the $10 offering price based on the percentage of increase in the Index. If the Index has increased by 10% or less from the starting value, the holder will receive $10.00 per unit. If the Average has increased by more than 10% from the starting value, the holder's original investment will be reduced based upon the percentage increase of the Average in excess of 10% from the starting value. As a result, the maturity payment may be less, and possibly significantly less, than the $10 offering price. See page TS-2 of the prospectus for further details on the calculation of the maturity payment, page TS-3 for hypothetical examples of the maturity payment, and page TS-8 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.
