*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	The number of Restricted Shares granted to the Reporting Person was determined by dividing the Reporting Person's 2006 stock incentive bonus dollar amount $3,866,667 by $92.70517 (the average of the high and low price of Merrill Lynch & Co., Inc. Common Stock (MER) on the grant date (January 22, 2007)). These Restricted Shares vest in four annual installments of 25% on January 31 in the years 2008 to 2011. The Restricted Shares are issued under the Merrill Lynch & Co., Inc. Employee Stock Compensation Plan. Transactions under this Plan are exempt under Rule 16b-3.
(2)	This total also reflects the acquisition of shares of Merrill Lynch & Co., Inc. Common Stock as a result of dividend reinvestment in a Merrill Lynch plan which is exempt from the reporting requirements under the provisions of Rule 16a-3 and/or 16a-11.
(3)	These Restricted Shares were granted on January 22, 2007 under the Merrill Lynch & Co., Inc. Long-term Incentive Compensation Plan. These Restricted Shares will vest and release 100% in January 2010. Transactions under this plan are exempt under Rule 16b-3.
Remarks: All reported positions have been rounded down to the nearest whole number.
