BIACORE APPOINTS NEW PRESIDENT OF BIACORE INC -
CHANGE WILL BRING A NEW COMMERCIAL APPROACH TO BIACORE'S U.S. SALES ORGANIZATION

Uppsala, Sweden, September 20, 2004.

Biacore International AB (Biacore) 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.
