24/7 Real Media

LYCOS, INC. AND 24/7 REAL MEDIA AMEND AND STRENGTHEN
MULTI-YEAR MEDIA SALES AND TECHNOLOGY AGREEMENT

NEW YORK – December 13, 2004 – 24/7 Real Media, Inc. (Nasdaq: TFSM), a pioneer in interactive marketing and technology, and Lycos, Inc. (www.lycos.com), a leading provider of search, community and technology lifestyle destinations and a wholly owned subsidiary of Daum Communications Corp. (KOSDAQ: 035720), a leading Internet portal in Korea, today announced the amendment of a multi-year strategic agreement for 24/7 Real Media to provide media sales, ad serving and analytics technology and services for Lycos’ U.S. Web properties.

The amendment follows the recent purchase of Lycos by Daum Communications and continues 24/7 Real Media’s sales representation of Lycos Web sites in the 24/7 Web Alliance. Lycos will also continue to use 24/7 Real Media’s Open AdSystem™ technology exclusively to serve all advertising, and to enable behavioral targeting, on all Lycos U.S. Web sites in the 24/7 Web Alliance. The amendment also permits Lycos to phase-in supplemental internal sales capabilities and eliminates 24/7 Real Media’s annual revenue guarantee, in favor of a minimum revenue commitment based on Lycos’ actual impression delivery.

David Kim, CEO of Lycos, Inc., said: “Clearly, few if any companies other than 24/7 have the breadth of products and services that can address Lycos’ strategic needs across our wide variety of content and user profiles. We are excited to let 24/7 do what they do best, freeing Lycos to rediscover the technology and product focus that once drove this company’s rich history.”

David J. Moore, chairman and CEO of 24/7 Real Media, said: “We are delighted that Lycos shares our vision of the future of interactive advertising, where publishers can access sales, ad serving and analytics to increase audience, revenue and profits, all via one relationship. We have high regard for Lycos’ new management team, and we look forward to working with it to maximize revenues and profits for both companies.”
