FROM     ROY M. MARTIN, JR.                TO       ALL DIALOG EMPLOYEES
         PRESIDENT AND CEO

DATE     AUGUST 7, 2001                    COPIES

SUBJECT  THE THOMSON CORPORATION
         SIGNS AGREEMENT TO ACQUIRE
         THE NEWSEDGE CORPORATION



Key goals of Thomson Legal & Regulatory include providing the broadest and most
powerful e-information solutions to the legal, regulatory and professional
market, and enhancing its position in the business news and corporate market
segments.

Today, I am pleased to announce that The Thomson Corporation has signed a
definitive agreement to acquire the publicly held NewsEdge Corporation, a
leading real-time news and current awareness provider in the online business
information market. Under the terms of the agreement, Thomson will make a cash
tender offer for all of the outstanding shares of NewsEdge common stock. The
acquisition is expected to close in the second half of 2001.

NewsEdge will operate as a stand-alone business within Thomson Legal &
Regulatory, and will be aligned with The Dialog Corporation. The core senior
management team of NewsEdge will remain with the company, and NewsEdge President
and CEO Clifford Pollan will report to me.

WHO IS NEWSEDGE?
With 2000 revenues of $70.9 million, NewsEdge is a global provider of content
solutions and electronic publishing technologies for business, and provides
real-time news and information products and services to approximately 1,500
corporations and professional services firms worldwide. NewsEdge employs more
than 280 people in 16 offices in eight countries around the world, with
approximately 200 of the employees based at its Burlington, Mass., headquarters.

NewsEdge combines proprietary technology, world-class content, and specialized
editorial processes to deliver tailored information and decision-support
solutions to

knowledge workers through three major lines of business - information and
decision-support services, content solutions and electronic publishing
technologies.

The acquisition of NewsEdge by Thomson will add an important new dimension to
existing Thomson Legal & Regulatory news and current awareness product
offerings. NewsEdge's unique strength in developing enterprise content and
decision support solutions helps its customers more easily navigate and unlock
the optimal value of all of their information assets.

DIALOG AND NEWSEDGE TOGETHER
Both NewsEdge and Dialog provide online information services for business,
science, engineering, finance and law professionals. While the companies serve
similar markets, there are significant points of differentiation between
products and services that make the two businesses complementary. Together, the
goal is to leverage our experience, market strengths and best practices to
enhance our value to all of our customers.

Please join me in welcoming our new NewsEdge colleagues and in wishing them
great success as part of Dialog and Thomson Legal & Regulatory.
