This partnership between a major western company and a global Japanese
technology company is believed to represent one of the UK's largest-ever export
orders for leading-edge software.

Fujitsu Limited is a leading provider of comprehensive information technology
and network solutions for the global marketplace. Comprising over 500 group
companies and affiliates worldwide -- including ICL, Amdahl and DMR Consulting
Group -- the Fujitsu Group had consolidated revenues of 5.24 trillion yen ($43.3
billion) in the fiscal year ended March 31, 1999. Fujitsu employs over 188,000
people worldwide (including 55,000 systems and service experts), has operations
in more than 100 countries and last year sold 3.82 million personal computers.
In the Japanese market, Fujitsu is one of the largest Internet service
providers, personal computer manufacturers and online service providers.

Dialog will receive multi-million dollar fees for licenses, services and
technology support in addition to royalties for sales of online services and
InfoSort sales (both English and Japanese language). Additional royalties
associated with new products and services under development are also included in
the agreement.

Dan Wagner, Dialog's Chief Executive, commented: "Fujitsu's interest in such a
wide ranging alliance was ignited by our acquisition of Knight Ridder
Information, which gave us a true global presence and expanded our breadth of
information services a hundred fold. For the past eighteen months, we have been
in negotiation with Fujitsu to conclude this landmark Agreement which endorses
the support received from those investors who have shared our vision since that
time.

"Fujitsu's global presence is immense, and the importance of their recognition
of our information and knowledge management leadership cannot be overstated. The
fact that they will be offering our online services and technologies as
preferred solutions to their vast global customer base accelerates InfoSort's
potential to become an industry standard worldwide.

"InfoSort has always been utilized to provide companies with the ability to
track external published data of value and relevance. Through today's agreement
and the complementary capabilities of Dialog and Fujitsu, companies will now be
able to do the same with their important internal information thus enabling them
to fully leverage their knowledge capital."

Mr. Tatsuzumi Furukawa, Fujitsu Member of the Board, Group President, Network &
Content Business Group commented: "We are very pleased to be in partnership with
such an innovative, leading company as Dialog. Since we first formed a
relationship with them in 1997, we have increasingly recognized the value and
quality of their knowledge management tools and technologies and the vast depth
and range of their information solutions.

"In the area of knowledge management and Intranet solutions, we are satisfied
that Dialog's InfoSort is the best software of its kind available today and with
this
   3
global alliance we look forward to working with Dialog to position it firmly as
an industry standard. "We are also aware of the increasing importance of
providing information solutions integrated tightly into our technology
solutions. Dialog is a global partner able to offer the range of information
solutions necessary to satisfy our broad and growing customer base.

"There is no doubt that as this new phase in our relationship develops, we will
be exploring other potential applications of Dialog's technologies and new areas
in which we can work together."

The agreement has important implications for the UK's role in the global
information age, an issue on which the Government has placed considerable
emphasis. British Prime Minister Tony Blair, stated: "I am delighted to send my
congratulations to The Dialog Corporation plc and Fujitsu of Japan on the
successful conclusion of a licensing agreement for world class knowledge
management software. It is indeed a significant step forward in the new global
knowledge economy.

"This is a significant and very welcome development in Anglo-Japanese trading
relations. Japanese companies generally, and market leaders such as Fujitsu in
particular, are renowned throughout the world for their adherence to the highest
quality standards of products and services and insistence on using the very
latest state-of-the-art technology. It is therefore a source of considerable
pride and satisfaction that they should have chosen to licence the technology of
a British company, The Dialog Corporation plc, to become their world-wide
standard for data management software."
