                             Safe-Harbor Statement

This presentation contains forward-looking statements within the meaning of the
"safe harbor" provisions of the Private Securities Litigation Reform Act of
1995. These statements are based on management's current expectations or
beliefs and are subject to a number of factors and uncertainties that could

release address the following subjects: expected date of closing the merger;
future financial and operating results; and timing and benefits of the merger.

The following factors, among others, could cause actual results to differ

costs related to the merger; failure of the Terra or Lycos stockholders to
approve the merger; inability to further identify, develop and achieve success

effect on pricing, spending, third-party relationships and revenues; inability
to establish and maintain relationships with commerce, advertising, marketing,
