Item 1.01.    Entry into a Material Definitive Agreement.

On October 17, 2005, Willis North America Inc. ("Willis"), a subsidiary of
Willis Group Holdings Limited (the "Company"), entered into definitive
documentation with respect to a new $300 million five-year revolving credit
facility (the "Facility"). The Facility completes the replacement of Willis'
bank loan agreement entered into in December 2003, which had included both a
revolving loan facility and a term loan facility. The term loans were repaid in
July 2005 from the proceeds of the $600 million public bond issue. This new
Facility replaces the $150 million revolving credit facility under the previous
agreement. The Facility provides for a $50 million sublimit for swingline loans.

The Facility will mature on October 17, 2010. The Facility is guaranteed by the
Company and other subsidiaries of the Company.

The covenants contained in the Facility include a maximum leverage ratio and a
minimum interest coverage ratio.

The Facility was provided by a group of fourteen financial institutions led by
Banc of America Securities Limited and Royal Bank of Scotland plc as Joint Lead
Arrangers. Banc of America Securities Limited is the Administrative Agent. The
Company has a number of other commercial relationships with the lenders under
the Facility.

The foregoing summary is qualified in its entirety by reference to the agreement
for the Facility, a copy of which is filed herewith and incorporated herein by
reference.
