         Willis Group Chairman and CEO Adopts 10b5-1 Share Trading Plan


    NEW YORK--(BUSINESS WIRE)--May 4, 2005--Willis Group Holdings
Limited (NYSE: WSH), the global insurance broker, announced today that
Chairman and Chief Executive Officer Joe Plumeri has adopted a
pre-arranged, personal trading plan in accordance with guidelines
specified by Rule 10b5-1 under the Securities Exchange Act of 1934.

       Rule 10b5-1 permits insiders to sell fixed portions of their
holdings over a designated period of time by establishing pre-arranged
written plans at a time when they are not in possession of material
non-public information.
       In the Company's 2005 Proxy Statement, the Compensation Committee
of the Company's Board of Directors indicated that, although Willis
utilizes its stock and options as a significant element of
compensation for employees, the Committee has encouraged Mr. Plumeri
and other Executive Officers to consider regularly disposing of
portions of their Willis stock in order to diversify their assets.
       Mr. Plumeri's Rule 10b5-1 plan, effective today, authorizes his
stockbroker to sell 2,350,000 shares of his Willis common stock in
installments commencing in June 2005. After giving effect, Mr. Plumeri
will continue to hold approximately 2.4 million shares and options of
Willis common stock.

defined in the Private Securities Litigation Reform Act of 1995. These
