Dear Colleague:

The year 2004 has been extraordinary for Grey. We won new accounts in every
region of the world. We grew with outstanding clients by advancing their
business. Our work bristled with intelligence, startling wit and unique
communications ideas. We continued to invest in people and capabilities that
expand our service offering. As a result, Grey continues on its successful track
and, even more important, most of our clients are doing very well.

We also took an historic step for our future, our people and our clients. We
agreed to merge our business into WPP, one of the largest marketing
communications companies in the world with many values in common with Grey. We
expect to conclude our merger next year and to continue to stay one Grey group
of companies, simply structured and singularly focused on our clients' business,
as always.

What makes Grey so compelling is our unique set of core strengths:

     o    Smart, dedicated, highly talented and client-focused employees

     o    A global network spanning over 80 countries and four geographical
          regions, each headed by outstanding empowered leaders

     o    One strong, top-tier global company in each important communications
          discipline, led by remarkable entrepreneurs who know each other well
          and understand the value clients place on coordinating and
          synchronizing all marketing efforts on behalf of their brands

     o    Some of the largest and best clients in the world--corporations that
          believe in the power of Grey to build their brands.

Virtually all of our companies performed well. Here are their highlights:

Grey Worldwide, one of the largest advertising agencies in the world, grew with
many of its clients. Notably in the US, we won Nokia, a European client since
1991, and Tanqueray gin, adding to an already impressive roster of Diageo
brands. New clients won included Bongrain cheese, Progressive Insurance and
Rayovac batteries in North America; the Australian Tourist Commission in Europe;
Banca Intesa in Italy; Deutsche Telekom T-Online in Germany; Top Toy (including
Toys "R" Us and BR Toys) for the Scandinavian countries; and Ciba Vision for
Asia.

PEOPLE. In every region, outstanding people joined us in key management
positions. In North America, we energized our creative drive at Grey Worldwide
when Tim Mellors, who had been Chief Creative Officer of Grey London in the late
'90s, rejoined us as Chief Creative Officer, and Chris Shumaker came from the
Martin Agency as EVP/Business Development.

In the EMEA region, we enriched London's creative flair by promoting Executive
Creative Director David Alberts to the new position of Chairman/ECD, and
appointing Karen Ellis to the new position of European Creative Director/Beauty.

Other significant European appointments: Carl Erik Kjaersgaard to CEO/Nordic
region, Frank Dopheide to Chairman/Chief Creative Director of Grey Dusseldorf,
Stefan Knieff to CEO of Grey Synchronized Partners in Germany and Dik Kliks to
the new position of General Manager, Grey Cells, the Netherlands.

In Asia-Pacific, we significantly strengthened regional leadership with the
appointment of Mike Amour, previously EVP/Global Account Director on Mars, to
CEO of GGG Asia Pacific, Martin Randall to head Grey Synchronized Partners, and
Kenny Wong to head GGG Shanghai. We relaunched GGG Singapore under Chris Leong
with Phil Mulholland as SVP/Business Development and Tay Guan Hin as Executive
Creative Director.

In Latin America, we appointed Francisco Garcia-Huidobro to lead Grey Chile and
Enrique del Azar to lead Grey Worldwide Argentina.

And as we welcome a new generation of talent, we are also saying farewell to two
Grey legends. Vice Chairman/General Manager Bob Berenson and Vice Chairman/Chief
Creative Officer Steve Novick recently announced their retirements, Bob after 40
years and Steve after 38. They have been two of my closest advisors and helped
make Grey the powerhouse it is today. We thank them for their extraordinary
contributions.


                                      * * *

In summary, 2004 was a year of achievement and anticipation. I have every
confidence we can continue to grow. I also believe our new relationship with WPP
will make us stronger. In my view, our greatest strength is you--your remarkable
talent and your ability to build our clients'

prosperous New Year.
