MORRISTOWN, N.J.--(BUSINESS WIRE)--April 7, 2004

Creates the Preeminent Supplier of Pharmaceutical Sales and

Marketing Solutions in Central and Eastern Europe

Dendrite International, Inc. (NASDAQ: DRTE) today announced the completion of its strategic acquisition of Medical Data Management (MDM), a privately held group of companies primarily based in Warsaw, Poland. MDM is the leading provider of physician databases, market research, and sales force support services to pharmaceutical companies in Poland, Hungary, Russia, and Ukraine.

The acquisition creates a comprehensive solutions and services company dedicated to the rapidly growing pharmaceutical market in Central and Eastern Europe (CEE), and further extends Dendrite's ability to provide leading solutions that drive promotional and sales effectiveness in this increasingly strategic region. The acquisition results in a combination of Dendrite's industry-leading sales effectiveness software and service solutions and MDM's physician databases, market research, and CRM application installation and support services.

Through the acquisition, Dendrite can now deliver a broader, richer array of services, combined with local market expertise and resources, and extend its reach into a number of growing markets. Pharmaceutical companies in turn can purchase their software and information-based solutions from a single source, which simplifies integration and provides a more comprehensive, cost-effective solution.

"During the past 18 months, Dendrite and MDM have actively partnered to promote sales effectiveness solutions and support services to the pharmaceutical industry in Central and Eastern Europe, and our combined offering has been enthusiastically embraced," said Dendrite Chairman and CEO John Bailye. "By acquiring MDM, we can create additional synergies and offer clients an unparalleled scope of services and depth of industry knowledge."

Added Wanda Lopuch, Ph.D., President and CEO of MDM, "Pharmaceutical companies across the CEE region are increasingly looking for best-in-class solutions, combined with local support and expertise, from a single provider in order to achieve their CRM objectives. By joining forces with a global leader such as Dendrite, we can offer our growing customer base a tremendously expanded and enhanced array of sales and marketing solutions and support."
