Mercer Launches New Global Brand Initiative Reflecting Expanded Business and Simplifies Its Name to ''Mercer''

Effective today, the simplified name "Mercer" will be the new
brand identification for Mercer Human Resource Consulting, the world's
largest human resource consultancy. The global brand initiative
reflects Mercer's full range of consulting, outsourcing and investment
services, many of which extend beyond the category of human resource
consulting. Mercer will continue to provide these integrated services
to more than 25,000 clients through 17,000 professionals at offices in
40 countries.

"The Mercer brand has been built on the world-class legacy created
by our people for more than 60 years," observed M. Michele Burns,
Chairman and Chief Executive Officer of Mercer. "In many markets
around the world, Mercer is recognized as one of the leading global HR
consulting firms, with outstanding expertise in human capital
management, retirement, compensation and health and benefits.

"The fact is, however, that Mercer provides a much broader array
of solutions than those for which we have traditionally been known,
and our business growth is fueled by a number of new initiatives,"
said Ms. Burns. "This expansion of capabilities has led to improved
financial performance. We have achieved four consecutive quarters of
revenue growth, with a gain of 12 percent in revenue for the most
recent quarter ended June 30, 2007 and improved profit margins in that
period.

"Our outsourcing solutions include customized administration,
technology and total benefit outsourcing. Mercer's investment services
include global leadership in investment consulting and multi-manager
investment management. This is in addition to offering consulting
services that help clients design and manage employee health, welfare
and retirement plans, and optimize human capital.

"We strongly believe that no other single firm can match the scope
of Mercer's offerings, the range of solutions we provide and the
talent, experience and dedication of our people," Ms. Burns noted. "We
deliver true end-to-end expertise, products and solutions across the
broad consulting, outsourcing and investments spectrum. Our
consultants work with clients to develop solutions that address global
and country-specific challenges and opportunities. We are experienced
in assisting both major and growing, middle-market companies."

Mercer's global client base not only includes most of the world's
leading companies and governments, but also comprises many rapidly
growing organizations, including those in some of the world's fastest
growing economies. These include nine of ten Fortune 100 firms, three
of four Fortune 1000 firms, two of three FTSE 100 firms and a majority
of Nikkei 225 firms. Some 60 percent of Mercer's clients are located
in Europe, Asia/Pacific and Latin America, indicating the geographic
reach of Mercer's services.

Mercer is communicating its broader range of capabilities and its
name change through a new advertising campaign, the creation of a new
summary of its corporate capabilities (which can be downloaded at
www.mercer.com/globalcapabilities) and the launch of the company's
newly redesigned website, which can be viewed at www.mercer.com.
