THOMSON RESPONDS TO CCBN.COM ALLEGATIONS

STAMFORD, Conn. and TORONTO, July 30, 2002 — In response to a press release issued by CCBN.com this morning announcing the filing of a lawsuit against The Thomson Corporation, Thomson issued the following statement, attributable to Richard J. Harrington, president and chief executive officer of The Thomson Corporation:

"Thomson categorically denies the allegations included in the CCBN.com lawsuit and intends to vigorously defend itself against this baseless claim.

This complaint is a result of CCBN.com's disappointment over ongoing negotiations. For months now — even as recently as last week — Thomson has been engaged in good faith discussions with CCBN.com to identify a workable business relationship. As such, we were surprised to read of the lawsuit this morning. Clearly, in light of today's environment, this suit is an exploitive attempt by CCBN.com to discredit Thomson among its customers and investors after they failed to achieve their desired outcome."
