  Willis Group Issues Statement on Eric Dinallo's Nomination to New York State
                            Insurance Superintendent

    NEW YORK--(BUSINESS WIRE)--Dec. 15, 2006--Eric Dinallo, General
Counsel of Willis Group Holdings, was today nominated by
Governor-elect Eliot Spitzer of New York to serve as New York State
Insurance Superintendent in the new administration. Joe Plumeri,
Chairman and CEO of Willis, issued the following statement:



        Eric Dinallo is an individual with tremendous integrity and
        leadership who will be a valuable addition to the team
        Governor-elect Spitzer is assembling. During Eric's
        wide-ranging career in both the public and private sector, he
        has demonstrated the ability to cut through complex legal and
        regulatory issues and pursue a principle-based approach that
        promotes transparency and fair play. There is near-universal
        agreement that the regulation of the insurance industry needs
        reform and Eric is well-suited given his time with Willis and
        previously with Morgan Stanley to oversee this effort in New
        York.

        Over the past year, Eric has brought a meaningful perspective
        and has made a significant contribution to our corporate
        governance efforts as well as to how we embrace risk-based
        assessments and the changing paradigm of insurance regulation.

        He has done an outstanding job and while we are sorry to be
        losing Eric, I appreciate his deep commitment to public
        service, and am confident he will make an important
        contribution in his new role in promoting regulatory reform
        and New York's economic growth.
