                  THE THOMSON CORPORATION ANNOUNCES COMPLETION
                 OF CASH TENDER OFFER FOR NEWSEDGE CORPORATION
-----------------------------------------------------------------

    TORONTO, SEPTEMBER 26, 2001--The Thomson Corporation (TSE:TOC) announced
today the completion of the cash tender offer by its indirect wholly owned
subsidiary, InfoBlade Acquisition Corporation, for all of the outstanding shares
of common stock of NewsEdge Corporation (NASDAQ:NEWZ). InfoBlade has accepted
for purchase and payment all shares of NewsEdge common stock validly tendered
and not properly withdrawn prior to the expiration of the cash tender offer.

    The tender offer expired, as scheduled, at 12:00 midnight (EDT) on Tuesday,
September 25, 2001. Based on a preliminary count; approximately 17,687,928
shares (including through notices of guaranteed delivery) of NewsEdge common
stock (constituting approximately 95% of the issued and outstanding shares of
NewsEdge common stock) had been validly tendered and not withdrawn. All of the
conditions to complete the cash tender offer have been satisfied. InfoBlade
shall promptly pay US$2.30 per share, net to the seller in cash, for all of the
shares of NewsEdge common stock validly tendered and not properly withdrawn
prior to the expiration of the cash tender offer.

    In the second step of the acquisition, Thomson plans to merge InfoBlade and
NewsEdge, with NewsEdge as the continuing entity. As a result, each share of
NewsEdge common stock not previously purchased in the tender offer will be
converted into the right to receive US$2.30 per share, net to the seller in
cash, except for those shares held by NewsEdge stockholders who seek appraisal
of their shares pursuant to applicable provisions of Delaware law. Under
applicable law, the proposed merger is not subject to the approval of the
remaining outstanding stockholders of NewsEdge.

    The Thomson Corporation (www.thomson.com), with 2000 revenues of
approximately US$6 billion, is a leading, global e-information and solutions
company in the business and professional marketplace. The Corporation's common
shares are listed on the Toronto and London stock exchanges.
