-- Future User Group Meetings planned

LION bioscience (Nasdaq: LEON) held its first annual Global User Group Meeting in Cambridge, UK, May 10-12. Over 80 participants from industry and academia shared insights into working with LION products, learned about future product developments, and discussed trends in informatics. In addition to these extensive discussions and live demos, several LION partners, such as Oracle, Microsoft, ChemNavigator, DeltaSoft, Celera and Silicon Genetics, showcased their collaborations with LION, and the products that resulted.

"LION has undergone several strategic changes recently, and I had been unsure about which direction they would finally go," said Peter Groenen of Organon. "In the current dynamics of pharma research there is strong need for technology providers who anticipate on our needs. As a result of the User Group Meeting, I have had my confidence in LION restored I am pleased with the route they are taking and look forward to their future developments. "

"It is very satisfying to see a software company such as LION bioscience realize that their company's future and the future of the field of life science informatics lies in the integration of bio- and cheminformatics," said Sarah Hunter of Biovitrum AB. "This year's user group meeting provided a unique opportunity for LION and its partners to share their vision with users such as myself and get instantaneous feedback. I certainly plan to attend next year's event."

LION bioscience plans to hold two US User Group Meetings in fall 2004. One will be hosted by AstraZeneca in Waltham, MA, September 29-30, and one will be held in San Diego, CA, in late October.
