New Amendments Part of Ongoing Review

NEW YORK, NEW YORK (October 23, 2006)—Marsh & McLennan Companies, Inc.

The amendments introduce the following new policies:

• Directors must acquire MMC equity with a value of at least $100,000 within three years of joining the board;

• Senior executives must attain specified levels of MMC equity ownership, based on a multiple of annual salary, over a five-year period;

• As a general matter, directors should not serve on more than four additional public company boards;

• A director elected by the board must stand for re-election at the next annual meeting of stockholders; and

• A director who has a significant change in employment or other personal circumstances must offer to resign.

Stephen R. Hardis, MMC’s independent chairman, said: “The board of directors continually looks for ways to improve MMC’s approach to corporate governance. The policies announced today result from an ongoing review, and are the latest in a series of governance enhancements implemented by the board over the last two years.”

Michael G. Cherkasky, MMC’s president and chief executive officer, added: “MMC is committed to strengthening all facets of its corporate performance. Striving to improve our governance practices is an important part of that process.”
