Ketchum and Prain Form Strategic Partnership in South Korea

Two Premier Communications Networks Formalize Partnership, Providing Clients Expanded Regional and Global Capabilities

SEOUL, South Korea and LONDON, June 7, 2010 - Ketchum, a leading global public relations agency, and Prain, the largest
integrated public relations firm in South Korea, announced today the signing
of an exclusive affiliate agreement in South Korea. The collaboration
provides Prain clients access to a world-class public relations network
outside of South Korea while providing Ketchum clients the public relations
services of the market leader in South Korea. Prain is an indigenous South
Korean firm, well-respected for its media relations, market research and
public affairs primacy for leading Korean and international consumer goods,
technology, healthcare, and automotive companies and brands.

"Ketchum's partnership with Prain will provide our clients with deep
local market insight and expertise in South Korea and a professional approach
that complements Ketchum extremely well," said Jon Higgins, Ketchum senior
partner and CEO of international operations. "We are confident that through
our relationship we will be able to deliver on a world-class client-service
proposition in this important, growing market."

"Prain and Ketchum share a passion for bringing clients truly outstanding
results to help them succeed in the marketplace," said Sung-bin "SB" Jang,
executive director, Prain. "Together, our strategic and creative
capabilities, combined with local insight and international reach make this a
compelling partnership. This marks an exciting milestone in Prain's 10-year
history."

Ketchum and its work with top global brands and corporations is well
recognized, having won numerous industry awards internationally, including
being honored with the Campaign of the Year by PRWeek U.S. for its work with
Dreyer's ice cream and Campaign of the Decade by the Holmes Report for its
work with Doritos (Frito-Lay). Noting the agency's long-standing client
partnerships, Ketchum was named Large PR Agency of the Year by the Holmes
Report, which also cites Ketchum's merger this year with number one European
communications consultancy, Pleon, as a major expansion to the agency's
international footprint in "a move that almost certainly elevated Ketchum
into the top four firms in the world."

Higgins will work closely with Prain as it is introduced and provides
service to Ketchum clients and neighboring North Asia operations, including
Ketchum Greater China, headed by Kenneth Chu, CEO, Greater China, and
Ketchum's strategic partner in Japan, Hakuhodo.
