services in the area of risk.  With the  addition  of Kroll,  we can now offer a
broader range of services  that will help clients  reduce the total cost of risk
to their  enterprises.  The combination of Marsh and Kroll creates a unique risk
services  firm with  global  capabilities.  In turn,  Kroll will  contribute  to
building  shareholder  value at MMC,  and we expect it to be  accretive to MMC's
earnings beginning in 2005."

"This  acquisition  represents  a new  era of  opportunity  for  Kroll  and  its
employees," said Mr. Cherkasky. "We are proud to be a part of an industry leader
