AdForce Announces European Presence and Plans International Expansion in Europe and Latin America Markets.

Business Editors/High-Tech Writers

CUPERTINO, Calif.--(BUSINESS WIRE)--June 20, 2000

New President of International Operations 

Leading Charge with Acquisition of Europe's AdTech

AdForce, LLC, a majority-owned operating company of CMGI, Inc. (Nasdaq:CMGI), and a leading online provider of centralized, outsourced ad management and delivery services, today announced it expects to open new offices across Europe and Latin America as part of its international expansion efforts in these two growing markets. Chief Financial Officer John Tanner, who recently was appointed President of International Operations, will lead the effort to capitalize on the considerable advertising potential stemming from growing European and Latin American PC-based and wireless Internet use.

In Europe, where the estimated number of Internet users is 60% that of U.S., AdForce currently serves many high-profile customers including Netscape International, 24/7 Europe, and, through its AdTech subsidiary, ad pepper media and Pilot. In March 2000, AdForce acquired AdTech, a leading European provider of third-party ad serving solutions, which serves ads throughout Western Europe. AdTech's headquarters, located in Frankfurt, Germany, serves as AdForce's European operations, customer service and development hub. In addition, AdForce has plans to open offices in London, Amsterdam, Paris and Madrid later this year.

"We've had very satisfying growth in Europe so far this year, more than quadrupling our ad serving from - 3 million impressions per day in December 1999 to 14 million per day in May 2000," said John Tanner, President of International Operations and Chief Financial Officer of AdForce. "A presence in Europe will better enable AdForce to take advantage of opportunities presented by the region's strong growth in Internet use."

In Latin America, AdForce plans to establish its presence as a premier provider of direct ad management from planned offices in Mexico City, Sao Paolo, and Buenos Aires, all major hubs of Internet activity in Latin America. Industry analysts project that online ad spending in Latin America will grow over $1.5 billion in the next five years.

Wireless advertising, already an area of strength for AdForce in the United States, is one international growth area being targeted by AdForce. The global wireless Internet market is expected to increase from 6 million people worldwide this year to more than 484 million people worldwide by 2005, according to wireless research by Ovum Ltd. Infrastructure reliability issues and higher landline phone charges mean adoption rates for wireless devices capable of supporting Internet access are higher in countries outside of North. As wireless Internet advertising opportunities grow in Europe and Latin America, AdForce believes its expertise in this area will contribute to the company's growth.

AdForce is now serving up to one half billion ads per day worldwide at rates of up to more than 7,000 digital advertisements per second. To support the delivery of all of these online ads, AdForce has an extensive national and international ad-serving infrastructure as well as strategic relationships with Akamai (Nasdaq:AKAM) and Digital Island that add over 2,000 servers located in over 100 countries.
