                          For Small Business


    NEW YORK--(BUSINESS WIRE)--June 28, 2007--Willis Group Holdings
Limited (NYSE:WSH), the global insurance broker, today announced the
acquisition of Chicago-based InsuranceNoodle, a leading internet
distributor of U.S. small business insurance. Terms of the transaction
were not disclosed.

    "We are very excited about this acquisition. Small business is a
big business growth opportunity for Willis," said Joe Plumeri,
Chairman and CEO, Willis, "InsuranceNoodle, with its state-of-the-art
internet technology and strong relationships with insurance carriers
and agents across the country, offers us a greatly improved,
lower-cost way to reach and service this key market in the U.S."

    InsuranceNoodle provides Willis with the following benefits:

    --A patented, proprietary web-based technology platform that
facilitates online application and quoting from multiple carriers for
a variety of commercial insurance products.

    --A cost-effective way to reach and service small business easily
and quickly and that offers unique solutions for franchise, affinity
and program opportunities.

    --A recognized brand with carriers and with retail insurance
agents and local brokers focusing on small business. InsuranceNoodle
currently has more than 2,500 active InsuranceNoodle Network agencies
across the country.

    --An electronically linked MGA, Noodle Specialty Brokers, offering
a broader array of products and services specifically designed for the
small business market.

    Willis' financial strength, management resources and business
expertise will drive significant development opportunities for
InsuranceNoodle. "We are equally enthusiastic about becoming part of
Willis," said InsuranceNoodle holding company CEO Don Urbanciz, "Our
alignment with Willis couldn't be better. We will use Willis'
strengths to develop more product and service offerings and deepen our
access to carriers. We in turn provide an innovative technology that
offers a distinct market advantage. InsuranceNoodle gives independent
agents a service edge by streamlining the placement of commercial
business in an insurance agent's office and providing elevated levels
of choice and speed to their clients."

    InsuranceNoodle's industry-leading technology platform will serve
as the new foundation for Willis Small Commercial, with Urbanciz named
North American CEO. Kathryn Emmerson will remain CEO of
InsuranceNoodle, which will continue to operate under its well-known
brand name as a division of Willis Small Commercial. Andrea Paris, who
prior to the transaction was promoted to lead the centralization of
Willis' small commercial business, continues in that role and will
assist the InsuranceNoodle management team in fully integrating its
business model into the company.

    "Willis and InsuranceNoodle are a strong strategic fit and also
share the same values and practices," said Mr. Plumeri, "We both have
a client-centric vision, excellent relationships with carriers, highly
skilled and experienced teams, a commitment to aggressive growth
targets, and an entrepreneurial, cost-conscious culture."
