as chief executive officer, MMC will realize this full potential and achieve
new levels of success.'

'I look forward to building on the legacy of success inherited from Ian
Smith,' Mr. Greenberg said. 'We have built our businesses into market leaders
by anticipating the needs of our clients, by providing trusted advice and
highly professional services and by promoting a spirit of partnership
throughout the company.  These qualities will continue to distinguish MMC's
approach.  I am also confident that we will find new ways to leverage the
exceptional skills and resources of our companies to create attractive new
business opportunities that will help us maintain high quality earnings,
generate increased value for shareholders and provide a stimulating
environment for our employees.'
