                      MMC HOLDS ANNUAL SHAREHOLDER MEETING
                          QUARTERLY DIVIDEND DECLARED



NEW YORK, May 17, 2007-Marsh & McLennan Companies, Inc. (MMC) announced at its
annual meeting today that its Board of Directors has declared a quarterly
dividend of $.19 per share on outstanding common stock, payable on August 15,
2007 to stockholders of record on July 6, 2007.

MMC also announced that stockholders re-elected Zachary W. Carter and Oscar
Fanjul to the Board of Directors, to serve three-year terms expiring in May
2010.

After 15 years on the board, Lewis W. Bernard decided not to stand for
re-election at the 2007 annual meeting. Non-executive chairman Stephen R. Hardis
and president and chief executive officer Michael G. Cherkasky publicly thanked
Mr. Bernard for his years of service to MMC and its stockholders.  Following Mr.
Bernard's retirement, the Board has 11 members.

In further business at the annual meeting, stockholders ratified the appointment
of Deloitte & Touche LLP as the company's independent registered public
accounting firm for 2007 and, as recommended by the Board of Directors, approved
an increase to the number of shares reserved under MMC's stock purchase plan for
international employees.  A stockholder proposal relating to political
contributions did not receive the number of votes required for approval.
