    Willis and New York Attorney General Agree to Amend Assurance
                           of Discontinuance

    NEW YORK--(BUSINESS WIRE)--Sept. 1, 2006--Willis Group Holdings
(NYSE:WSH), the global insurance broker, announced today that it has
signed an agreement with the New York Attorney General and the
Insurance Department of New York amending its Assurance of
Discontinuance (AOD) with regard to how Willis is compensated when
performing functions as a managing general agent (MGA). The amendment
recognizes that in MGA operations the Company is representing, acting
on behalf of, and performing services for the insurer and therefore
provides flexibility as to the insurer compensating Willis for these
services.
    "We've always received even treatment from the Attorney General's
Office; we expected this determination and are pleased with this
amendment to our AOD," said Joe Plumeri, Willis Group Chairman and
CEO. "When working as an MGA, we represent the interests of an
insurance company so this change to the AOD is consistent with our
position of being paid by our client. It also reaffirms our commitment
to full transparency - such that there are no questions as to who we
represent. Further, I appreciate the Attorney General's willingness to
engage in this conversation to gain a thorough understand of the many
nuances of the insurance broking business model."
