Explanation of Responses:

* 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 Management Development and Compensation Committee (the MDCC) of the Board of Directors of Merrill Lynch & Co., Inc. (the Company) determined that the Company will not pay bonuses to executive officers for performance in 2007. On January 28, 2008, the MDCC approved performance-based retention grants to members of continuing executive management of the Company including Ms. Berkery. The grants were made to promote the continuity of the management team and create further alignment with shareholders. This transaction is exempt under Rule 16b-3
(2) These stock options will be exercisable into shares of common stock. The exercise price of all of the stock options is $55.593, the fair market value of the Company's common stock on January 28, 2008, the date of grant.
(3) To ensure significant retention value, the grants will not be exercisable and will not be subject to retirement treatment prior to January 28, 2010. One-third of the stock options granted will become exercisable after January 28, 2010. The remaining two-thirds of stock options granted will become exercisable after that date only if specified stock price targets are achieved at any time after the grant date as follows: (A) one-third of the total grant will become exercisable if the average closing price of the Company's common stock over any 15-day trading period reaches $80.00 per share and (B) the last third of the total grant will become exercisable if the average closing price of the Company's common stock over any 15-day trading period reaches $100.00 per share. The exercise price of all of the stock options is $55.593, the fair market value of the Company's common stock on January 28, 2008, the date of grant. If the hurdles are not met, the grants will not become exercisable.
(4) The full terms of these retention grants are described in a Current Report on Form 8-K to be filed by the Company contemporaneously with this filing.
