         "The value of the strategic fit between Interpublic and NFO is becoming
clearer and more pronounced as a result of the dramatic changes occurring
globally throughout the marketing and media landscape," said Philip H. Geier,
Jr., Chairman and CEO of Interpublic. "Because of the rapidly changing business
environment, clients of all sizes and types are demanding more consumer
knowledge and insight as a component of marketing programs as well as the faster
delivery of this information. These are exactly the areas where NFO excels. So
with NFO now part of the Interpublic family, our set of core global competencies
will now range from the basics of consumer understanding to the ultimate in
marketing communications delivery."

         John J. Dooner, Jr., President and COO of Interpublic, noted that NFO
would very quickly be introduced to IPG client opportunities as well as its
experience operating in a global environment. Mr. Dooner said: "We have been
very impressed by NFO's consistent record of research innovation in all areas,
including market evaluation, product development, brand management, customer
satisfaction, pricing, distribution, and advertising effectiveness. We will now
move ahead together not only to share client opportunities but to develop new
analytical and measurement tools to better help all of our combined clients
better manage and expand their businesses."

         "We are delighted to join the Interpublic family of companies and are
excited about the opportunity to grow all of NFO's businesses at an accelerated

Executive Officer of NFO Worldwide. "Interpublic recognizes the importance of
providing high quality market research services and the role technology is
having in the way information is gathered, distributed and used. As we begin to
cross-fertilize ideas and clients, we look forward to benefiting from IPG's
decades of knowledge and success in doing business around the world," Lipner
continued.
