Uppsala, SWEDEN


UPPSALA, Sweden, Sept. 20, 2004 (PRIMEZONE) -- Biacore International AB (Biacore) (Stockholmsborsen: BCOR) announces that it has appointed Mr. Jerry Williamson as the new President of Biacore Inc. Mr. Williamson will assume his new role immediately and will play a vital role in positioning Biacore's U.S. sales organization to maximize the potential of the Company's product offering in the world's largest life science instrument market. Mr. Williamson takes over from Mr. Thomas P Wida who is leaving the Company.

Mr. Williamson, who was until recently the President of Pyrosequencing Inc., has over eighteen years experience working in the U.S. life science industry. At Pyrosequencing, he was responsible for increasing the U.S. sales of the company significantly while at the same time bringing costs down to more appropriate levels. Mr. Williamson joins Biacore from Beacon BioPartners, a strategic and business consultancy focused on the life science sector where he was the Managing Partner. Prior to joining Pyrosequencing in 2000, Mr. Williamson worked for a number of emerging biotechnology companies, as well as major industry heavyweights such as Roche. His experience includes sales management, marketing, business development and recruitment.

Mr. Erik Wallden, President and CEO of Biacore commenting on today's appointment said "I am pleased to welcome Jerry on board. I am sure his vast experience of the U.S. life science industry will allow him to bring a new commercial dynamic to Biacore Inc's operations." It is clear from our review of Biacore's business activities that we need to bring a new, much more aggressive commercial culture to our U.S. activities. This will enable us to maximize the potential of our full range of products for protein interaction analysis and deliver the sales that I believe we are capable of achieving in the world's most important life science instrument market.

"I would at this point like to express my thanks to Tom for all his work over the last several years and wish him every success in his future career." Mr. Wallden added.

The cost that Biacore incurs for the termination of Mr. Wida's contract will be reported in the third quarter 2004 and is estimated at approximately SEK 3.2 million.

Biacore is currently undertaking a strategic business review focused on a number of areas of the Company's operations including its sales processes. Biacore expects to announce the full results of this business review on or before its 3rd Quarter results which are due to be announced 21st October 2004.
