Item 1.01.        Entry into a Material Definitive Agreement.

On May 28, 2008, Willis Group Holdings Limited, Willis North America Inc. and
Willis of New York, Inc. (collectively, the "Company") entered into the Fourth
Amendment (the "Fourth Amendment") to the Assurance of Discontinuance, as
amended (the "AOD"), with the Attorney General of the State of New York and the
Superintendent of Insurance of the State of New York (the "Superintendent"). The
Fourth Amendment amends the AOD to permit the Company to acquire insurance
brokerage companies and entities that currently accept contingent compensation
and phase-out contingent compensation from the newly acquired entities on
business placed on behalf of existing clients over a three year period,
consistent with the terms and conditions of the AOD. As amended by the Fourth
Amendment, the AOD provides that the Company, in connection with its
acquisitions of brokerage companies, will be allowed to transition such regional
and local brokerage companies from their current compensation practices to a
transparent, clear, and conflict-free compensation practice.

In addition, on May 29, 2008 the Company was granted relief from the requirement
under Paragraph 21 of the AOD to file annual insurer compensation reports with
the Superintendent.

A copy of the Fourth Amendment is attached hereto as Exhibit 10.1 and is
incorporated herein by reference. The Company filed a copy of the Assurance of
Discontinuance as Exhibit 10.25 to Form 10-Q dated May 6, 2005. The Company
filed a copy of the Second Amendment to the Assurance of Discontinuance as
Exhibit 10.1 to Form 8-K dated August 31, 2006. The Company filed a copy of the
Third Amendment to the Assurance of Discontinuance as Exhibit 10.1 to Form 8-K
dated August 22, 2008.
