MERRILL LYNCH TO WITHDRAW PACIFIC EXCHANGE LISTING, RETAINS NEW YORK STOCK EXCHANGE LISTING

NEW YORK, NY- December 15, 2006 - Merrill Lynch & Co., Inc. (NYSE: MER]) today announced plans to withdraw the listing of its common stock from NYSE Arca, Inc., formerly the Pacific Exchange. Merrill Lynch & Co., Inc.’s common stock will continue to be listed on the New York Stock Exchange.

Merrill Lynch has decided to withdraw its listing from NYSE Arca, Inc. to streamline operations and eliminate duplicative administrative requirements inherent with dual listings as a result of the NYSE Group’s recent merger with Archipelago Holdings, the parent company of NYSE Arca. The withdrawal is expected to be effective within the next month.

Merrill Lynch does not believe that withdrawing its listing from NYSE Arca, Inc. will have any impact on the liquidity of its stock. NYSE Arca will continue to trade Merrill Lynch & Co., Inc. stock on an unlisted trading privilege basis.
