MMC to Propose Declassification of Its Board of...

Marsh & McLennan
                  Marsh & McLennan Companies, Inc. (MMC) today announced that its Board of
Directors has decided to eliminate its current three-class structure, subject to
shareholder approval. As a result of the Board's declassification, all directors
would become subject to annual election as their existing three-year terms
expire. MMC will include in its 2008 proxy statement a company-proposed charter
amendment that would effect the Board's declassification, and will ask
shareholders to approve the charter amendment at MMC's annual meeting in May
2008.

Stephen R. Hardis, chairman of MMC's Board of Directors, said, 'The decision to
declassify is the latest step in the Board's ongoing effort to implement best
corporate governance practices at MMC.'
