Willis Group Holdings Adds Three Independent Directors; Adopts New
Corporate Governance Guidelines

    NEW YORK--(BUSINESS WIRE)--March 4, 2004--Willis Group Holdings
Limited (NYSE:WSH), the global insurance broker, today announced
significant changes to its Board of Directors as well as the adoption
of new corporate governance guidelines. Both actions strengthen the
company as it moves into the next phase of building the world's
greatest insurance brokerage firm.
    The Board changes include the resignation of three directors
associated with Kohlberg, Kravis, Roberts & Co. L.P. and the
appointment of three new directors. The transformation of the Board,
which becomes effective as of the next regular board meeting on April
21, 2004, follows KKR's recent successful sale of 24 million shares of
Willis stock, reducing its ownership to approximately 7.5% of
outstanding shares.
    The three resigning directors are Henry R. Kravis, George R.
Roberts and Todd A. Fisher. Messrs. Kravis and Roberts are co-founding
partners of KKR. Mr. Fisher has been an executive of KKR since 2000.
The three new directors are Joseph A. Califano, Jr., Wendy E. Lane and
James F. McCann.
    Mr. Califano, 72, has served in senior policy-making positions in
both the public and private sectors. Since 1992, he has been Chairman
of the Board and President of the National Center on Addiction and
Substance Abuse at Columbia University in New York City. Mr. Califano
has served as Adjunct Professor of Public Health at Columbia
University's Medical School and School of Public Health since 1992 and
is a member of the Institute of Medicine of the National Academy of
Sciences. Mr. Califano was senior partner of the Washington, D.C.
office of the law firm Dewey Ballantine from 1983 to 1992. Mr.
Califano served as the United States Secretary of Health, Education
and Welfare from 1977 to 1979. Mr. Califano is a director of Automatic
Data Processing, Inc. and Viacom, Inc.
    Ms. Lane, 52, has been Chairman of Lane Holdings, Inc., an
investment firm, since 1992. Prior to forming Lane Holdings, Inc., Ms.
Lane was a Principal and Managing Director of Donaldson, Lufkin and
Jenrette Securities Corporation, an investment banking firm, serving
in these and other positions from 1980 to 1992. Ms. Lane is a director
of Laboratory Corporation of America, a position she has held since
1996. Ms. Lane has spoken on business ethics on numerous occasions to
senior executive and director forums and consortia at various
institutions, including Harvard Business School and Stanford Law
School.
    Mr. McCann, 52, is a highly successful entrepreneur, having bought
a small New York City flower shop in 1976 and built it into
1-800-Flowers.Com, Inc. where he serves as Chairman and Chief
Executive Officer. Active in numerous business and community
organizations, Mr. McCann is on the national boards of directors of
Gateway 2000, the National Retail Federation, Boyd's Bears, and Very
Special Arts, as well as the boards of Hofstra University and
Winthrop-University Hospital.
    The Board of Directors also adopted new corporate governance
guidelines, which meet the requirements of the Sarbanes-Oxley Act and
the new listing standards recently adopted by the New York Stock
Exchange. The statute and the NYSE listing standards require, among
other things, that by the time of the Company's 2004 Annual General
Meeting a majority of the Company's board be independent and that the
Board's Audit Committee, Compensation Committee and Corporate
Governance and Nominating Committee be comprised solely of independent
directors. The board reconstituted the membership of these committees
to ensure that all members are independent within the meaning of the
new requirements.
    In announcing the changes, Joseph J. Plumeri, Chairman of the
Board and Chief Executive Officer of Willis said, "We are completely
committed to the highest standards of corporate governance. The
changes we have made today are part of that commitment. We very much
appreciate the invaluable service Henry Kravis, George Roberts and
Todd Fisher have provided to Willis throughout the six years of their
involvement with the Company, and we are particularly pleased that Joe
Califano, Wendy Lane, and Jim McCann have agreed to bring their
experience, energy and fresh perspective to our board. The three
individuals joining our board are each stand-outs in their own right.
Collectively, they add tremendous strength as we move into the next
phase of our mission to build the world's greatest insurance brokerage
firm."
