August 7, 2001

Dear NewsEdge Customers and Partners:

Today marks an important and exciting day for NewsEdge and its customers and
partners. Today, NewsEdge and The Thomson Corporation are announcing a
definitive agreement under which Thomson will acquire NewsEdge by way of a cash
tender offer to be made by a newly formed subsidiary of Thomson.

We think this is great news for our company and our customers. NewsEdge will be
part of one of the world's premier e-information solutions companies - one that
has a tremendous reputation for technology innovation and product excellence. On
the strength of brands such as Dialog, Westlaw, SAEGIS, First Call/Thomson
Financial and Primark, Thomson is the benchmark against which all other
information companies are often measured.

NewsEdge will continue as a stand-alone business, aligned with Dialog, a
worldwide leader in providing online-based information services to organizations
seeking a competitive advantage. For NewsEdge, this means the considerable
resources and reach of Thomson are now part of our essential DNA. For our
customers, Thomson resources - specifically technology expertise, world-class
content and editorial authority - are expected to be the catalyst for new
features, functionality and usability for NewsEdge products that we believe will
deliver even more power and value for you and your business.

In the near term, we expect your relationship with NewsEdge will to continue
unchanged. Moving forward as part of Thomson, our focus will be on developing
new products, refining current products and defining the next standard in
content solutions, real-time news and information, and electronic publishing
technologies.

We currently anticipate that this transaction will close in the second half of
2001, subject to the tender of a majority of eligible shares of NewsEdge and
other customary closing conditions. We look forward to sharing more information
on our progress soon. In the meantime, we encourage you to contact your NewsEdge
sales representative with any questions you may have.

Respectfully,


Clifford Pollan                           Roy M. Martin, Jr.
President and CEO                         President and CEO
