Ulf Jonsson Leaves Biacore, Erik Wallden Appointed New President and CEO

Uppsala, SWEDEN


UPPSALA, Sweden, July 19, 2004 (PRIMEZONE) -- Biacore International AB (Biacore) (Stockholmsborsen:BCOR) today announced that an agreement has been made between the Board of Biacore International AB and Dr. Ulf Jonsson to the effect that Ulf Jonsson will leave his position as President and CEO with immediate effect. He also resigns from the Board of Directors.

Pending permission from the Companies Registration Office, the Board has appointed Mr. Erik Wallden, at present Executive Vice President and Head of marketing and business development, new President and CEO of Biacore International AB. This permission is needed due to the residency requirements in the Swedish Companies Act. However, pending such possible permission, Erik Wallden will assume the obligations of a President in his capacity as Executive Vice President.

Mr. Lars-Goran Andren, Chairman of Biacore International AB, says: "Ulf Jonsson has made an exceedingly important contribution to Biacore's development since the Company was founded. We owe him sincere thanks for his devoted efforts to make Biacore the global leader in SPR technology. At the moment, however, we believe that the Company would benefit from additional commercial focus, and that resources should be redirected accordingly. With his extensive commercial experience from the international Life Science Industry, we believe Erik Wallden has the right background to achieve these ambitions and we wish him great success in his new task."
