                             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
cause actual results to differ materially from those described in the
forward-looking statements. The forward-looking statements contained in this
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
materially from those described in the forward-looking statements: the risk
that the Terra's and Lycos' businesses will not be integrated successfully;
costs related to the merger; failure of the Terra or Lycos stockholders to
approve the merger; inability to further identify, develop and achieve success
for new products, services and technologies; increase competition and its
effect on pricing, spending, third-party relationships and revenues; inability
to establish and maintain relationships with commerce, advertising, marketing,
technology, and content providers.

For a detailed discussion of these and other cautionary statements, please
refer to Terra's filings with the Securities and Exchange Commission, including
the Risk Factors section of Terra's F-1 filing that became effective in
November 1999, and Lycos' filings with the Securities and Exchange Commission,
including the section titled "Factors Affecting the Company's Business,
Operating Results and Financial Condition" of the Management's Discussion and
Analysis in its From 10-K for the year ended July 31, 1999 and the Risk Factors
section of Lycos' S-3 filing that became effective in March, 2000.
