                                       Q&A
                          AUDIENCE: NEWSEDGE EMPLOYEES

WHY IS THE THOMSON CORPORATION PURCHASING NEWSEDGE?
The acquisition underscores the Thomson commitment to provide the broadest and
most powerful e-information solutions to the legal, regulatory, government,
corporate, financial and other professional markets. NewsEdge is seen as a key
to supporting the Thomson strategy of integrating its information and technology
tools within the daily work processes of its customers. Its products will add a
new dimension to existing Thomson Legal & Regulatory news and current awareness
products, and will complement its core primary and secondary legal and
regulatory products and services.

WHAT IS THE STRATEGIC SIGNIFICANCE OF THIS ACQUISITION? (WHERE DOES NEWSEDGE FIT
IN?)
NewsEdge will help to strengthen the Thomson Legal & Regulatory position as a
leading information solutions provider to legal, tax, accounting, government,
corporate, financial and other professional markets. NewsEdge's strength in the
corporate market will enhance Thomson Legal & Regulatory marketing efforts
within this customer group. We expect that NewsEdge also will help to support
and expand key relationships with customers, functional user groups and
information provider partners.

WILL NEWSEDGE MAINTAIN ITS AUTONOMY?
NewsEdge will operate as a stand-alone business within the Thomson Legal &
Regulatory market group, aligned with The Dialog Corporation. The core senior
management team will remain with the company, and NewsEdge President and CEO
Clifford Pollan will report to Dialog President and CEO Roy Martin.

WHAT IS THE CULTURE LIKE AT THOMSON LEGAL & REGULATORY?
There are both individual company cultures and a corporate culture within
Thomson Legal & Regulatory, and they co-exist quite well. Thomson Legal &
Regulatory allows each market-driven organization to retain the unique culture
that has enabled its success while developing an appreciation for Thomson Legal
& Regulatory businesses and people. In the past Thomson Legal & Regulatory has
enjoyed its greatest moments when companies have come together to share best
practices and knowledge and leverage one another's strengths.

Overall, Thomson Legal & Regulatory believes you will find that the culture is
similar to NewsEdge in that both organizations place a high priority on
customers and brand development. Thomson Legal & Regulatory is increasingly
collaborating across the organization to develop and deliver not just individual
products, but tailored solutions that give Thomson Legal & Regulatory a real
competitive advantage.

WHAT IS INVOLVED IN THE TRANSITION PROCESS?
Thomson has extensive experience acquiring and integrating new companies. For
each acquisition, it sets up integration teams that work hard at the business
unit and functional levels to ensure that these companies are rapidly and
successfully integrated into the Thomson systems and organization. Our track
record has been excellent.

You will find that the Thomson Legal & Regulatory market group is experienced
and works very quickly during integrations to avoid a prolonged period of
uncertainty for employees and to get the businesses moving forward together.

WILL NEWSEDGE HEADQUARTERS REMAIN IN BURLINGTON, MASS.?
Yes.

WILL THERE BE A REDUCTION IN WORK FORCE AT THE NEWSEDGE CORPORATION?
It would be premature to speak to this issue before we have a chance to really
learn about the business, and the people supporting it, firsthand.We are making
this acquisition in order to grow our Thomson Legal & Regulatory business. We
will be integrating the businesses to achieve maximum value for our customers
and the right environment for our people. Our objective is to sustain the
quality and depth of both organizations.

We appreciate the talent that comes with the acquisition. We will keep you
informed if and when there is a decision that affects you. The best we can all
do to prepare for this major integration is to conduct business as usual, finish
the year strongly and get 2002 off to a good start. The acquisition makes both
companies stronger in many respects and will

<Page>

create more opportunities within each of our businesses to develop and deliver
new products to best serve our customers.

HOW WILL THIS IMPACT NEWSEDGE EMPLOYEES?
We hope the impact will be positive. The new combined business is expected to
have more support for faster growth and profitability and greater ability to
compete. Individual employees will likely see the rewards of that growth, as
well as enhanced benefits and career development. We will strive to be timely
and honest in our communications. We have not yet explored how many overlapping
efforts could lead to combining individual or department roles with other
Thomson Legal & Regulatory businesses or organizations. However, there are areas
where the potential of growth will mean more resources.

WILL MY BENEFITS AND COMPENSATION CHANGE?
In the near term, your compensation, insurance and 401K will remain the same. In
the coming months, you will receive benefits information from The Thomson
Corporation. Open enrollment is in the fall, and any changes in your benefits
will begin next year.

HOW DOES THIS ACQUISITION AFFECT MY NEWSEDGE STOCK OPTIONS?
The company is being acquired at a per-share price of $2.30. All stock options
will be cancelled upon completion of the transaction. Each employee holding
outstanding options that are exercisable as of the closing of the transaction
will be entitled to receive, in exchange for the cancellation of each option, an
amount of cash equal to the excess of the $2.30 per-share price in the tender
offer over the per-share exercise price of the option, multiplied by the number
of shares of common stock underlying the option.

WHAT CHANGES WILL THERE BE IN MY DAY-TO-DAY WORK?
Upon completion of the transaction, questions about day-to-day operations, as
well as any questions about stationery, forms, expense and purchasing
procedures, etc., will be addressed by your supervisor or Human Resources
manager.

WHAT DO I TELL CUSTOMERS?
Our goal for the combined business is to be the foremost provider of
e-information solutions to the legal, compliance, tax, accounting, government,
corporate, financial and other professional markets worldwide. While it may be
tough to anticipate all of the detailed questions that customers may ask you,
here are some things you CAN tell customers if they ask:

o     Upon completion of the transaction, NewsEdge will enhance the Thomson
      position in legal, compliance, tax, accounting, government, corporate,
      financial and other professional markets. NewsEdge will be aligned with
      Dialog, as part of the Thomson Legal & Regulatory market group. This
      acquisition underscores the commitment by Thomson Legal & Regulatory to
      provide the broadest and most powerful e-information solutions to the
      market segments we serve.

o     The merger is expected to provide convenient access to more products and
      services and new combinations of products and services that better meet
      our customers' needs.

o     NewsEdge is seen as a key to supporting the Thomson strategy of
      integrating its information and technology tools into customers' work
      processes.

ARE DIALOG AND NEWSEDGE CURRENTLY SERVICING THE SAME CUSTOMERS? DO THE COMPANIES
COMPETE?
Dialog and NewsEdge are actually very complementary. The companies share some of
the same target markets, such as large companies and information-intensive
organizations. But the principal services provided - NewsEdge's news and current
awareness and Dialog's vast collection of essential information - are different.
We expect customers to benefit from the combination. Also important to note is
that NewsEdge delivers services to large numbers of knowledge workers' desktops,
broadening the reach of Dialog's traditional market within the professional
information marketplace.

NEWSEDGE HAS MANY CUSTOMERS IN THE FINANCIAL MARKETS AND DELIVERS SERVICES FROM
THOMSON FINANCIAL, SUCH AS FIRST CALL AND DISCLOSURE. WHAT WILL HAPPEN TO THE
NEWSEDGE FINANCIAL CUSTOMER BASE AND THE RELATIONSHIP WITH THOMSON FINANCIAL
PARTNERS? The acquisition should not impact NewsEdge's relationship with any
customer. Moving forward, there may be an opportunity to explore synergies or
cross-selling opportunities with NewsEdge and other Thomson companies.
