WALTHAM, Mass.--(BUSINESS WIRE)--Feb. 29, 2000

Lycos, Inc. (Nasdaq:LCOS) one of the most visited Web destinations in the world, today announced the launch of Lycos Free Internet Access (http://free.lycos.com), a high quality, free dial-up access offering made possible through an agreement with 1stUp.com Corporation, a leading provider of ad-supported Internet access solutions and a majority-owned operating company of CMGI, Inc. (Nasdaq:CMGI). The addition of Lycos Free Internet Access to the Lycos Network provides users with the popular online services they want without making them pay for access to resources that are free.

"Lycos has seen exceptional growth in page views and registrations over the last few years," said Bob Davis, president and CEO of Lycos. "We have always relied, however, on an access service to provide that essential connection to the Web. With today's announcement we now combine our premium content with Internet access. We are extremely excited by the potential this represents for the company."

Free Internet access has been a growing force in the marketplace for the last several months. Yet while the costs of Internet access have been eliminated, many free Internet access services have struggled to assemble their own features and content in order to meet consumers' needs. Lycos Free Internet Access bridges these basic requirements offering consumers everything -- unlimited online usage as well as outstanding content and community products through an easy-to-use interface -- and eliminates the need to pay the $20 or more each month that many online services charge. With each account, users receive unlimited high-quality Internet use, any number of email accounts, a My Lycos personalized start page, instant messaging and a personal homepage. Also, there is no limit to the number of accounts each individual or business may open and no restriction on home versus office use. Connection is available at speeds up to 56K and can be accessed through most local area networks installed in businesses.

"1stUp.com is proud to be powering the Lycos Free Internet Access offering," said Charles Katz, president and CEO of 1stUp.com. "This service marks a turning point in the free access movement. By combining 1stUp.com's technology and infrastructure with Lycos' brand and leading network of Web resources, consumers are growing to realize that there is a better alternative to paid Internet subscriptions."
