Havas Worldwide Announces Senior Executive Promotions

Two Moves Reflect the Company's Major Recent Successes

NEW YORK, April 21, 2010 - David Jones, global CEO of Havas Worldwide and Euro RSCG Worldwide,
announced today that Matt Ryan, global CMO of Euro RSCG, has been promoted to
president of global brands for Euro RSCG Worldwide and global CMO of Havas
Worldwide. Naomi Troni, formerly global new business director of Euro RSCG
Worldwide, has been promoted to global CMO of that company.

The moves reflect a period of major successes and expansion for Havas
Worldwide, one of the world's largest marketing communications agencies.
Recent months at Euro RSCG Worldwide, the world's largest agency network by
number of global accounts, have seen major new business wins with
international brands such as Heineken, AkzoNobel's Dulux, Credit Suisse and
Pernod Ricard's Jacob's Creek, plus major digital wins including IBM's global
digital business, EDF, Heineken and Lacoste, and being named to the Unilever
global digital roster. In 2009, Euro was named digital agency of record
and/or social media agency of record for such clients as Barilla, Clearasil,
GSK, Ikea, method, P&G, sanofi-aventis, Shire Pharmaceuticals and Sprint.

"We put digital at the core of our agencies globally back in 2005, a
model that has proven very successful for us. But the other big agencies are
now starting to do the same and catch up," said Jones. "Matt and Naomi's key
challenge in their new roles will be to ensure that we stay at the forefront
of the industry, especially in digital. They are two of the company's
brightest stars, and these appointments reflect their achievements and our
ambition."

Ryan joined Euro RSCG from Havas sister company Arnold Worldwide, where
he was executive director running the global Volvo relationship. Prior to
joining Arnold, Ryan was consulting to Gillette, P&G, Wyeth, Novartis, Ford,
Shell, Absolut Vodka, Mitsubishi and other leading global marketers on agency
model configuration, agency selection and compensation as a principle of Roth
Associates.

During Ryan's tenure as global CMO of Euro RSCG Worldwide, he led global
new business efforts, helped develop best practices for the network's
business development organization and assisted in growing global brands.

"I've spent the last 10 years of my career working hand in hand with
global advertisers to help ensure that they are building brands and
businesses in the most efficient yet lasting way possible," said Ryan.
"Working with global organizations is not only the area where I have spent
the majority of my time, it's also the area of our industry I enjoy the
most."

Troni, who spent two years as Euro's global new business director, will
now be responsible for managing the network's global new business and
marketing practices. In this role, she will leverage regional new business
successes and promote marketing best practices across all 233 Euro RSCG
Worldwide offices.

"I'm hugely excited in my new role to build on our new business successes
over the last few years," said Troni, "and promote best practices from around
the globe to bring to bear on global and regional new business efforts."

Before working as global new business director of Euro RSCG Worldwide,
Troni led new business and client development for Euro RSCG's London agency,
as well as business development and integration across the Euro RSCG U.K.
group. During her tenure, the U.K. agency won more than US$200 million in new
billings from brands such as News International, Staples, Superdrug and LG
Electronics. Troni also ran the relationship with News International.

This year, Euro RSCG Worldwide has also been named Adweek's first-ever
Healthcare Agency of the Year, runner-up for Global Agency of the Year from
Campaign, No. 2 on the Ad Age Agency A-List and European Communication Group
of the Year by Les Agences de l'Annee. And for the 12th time in 16 years,
BETC Euro RSCG was named Creative Agency of the Year by CB News Hits d'Or.
