LONDON, October 11, 2010 - Yvan Legris has been appointed as the chief executive officer UK, Europe,

leading provider of human capital consulting and outsourcing services.

"Now that all the procedures and approvals of the deal are completed, I
am thrilled to be taking on this leadership role. It was clear that Aon and
Hewitt were genuinely complementary organisations and now as a united firm we
can provide our clients with a wide range of cost-effective human capital and
risk solutions to help them solve their most complex business challenges.

"In the UK, mainland Europe, the Middle East and Africa, Aon Hewitt now
has more than 5,500 employees in 20 countries, making us an organisation with
tremendous breadth and depth of resources. We employ some of the top
professionals in the fields of retirement, benefits, investment, HR and
reward and we advise clients who range from purely local companies, to some
of the world's largest multinationals. Our clients have rewarded us with
incredible loyalty and I firmly believe that we are now even better placed to
tackle some of the key issues that they face in the coming years."
