Bachem Enlarges Corporate Executive Committee

16th September 2008

Bachem announced today that Dr. Lester Mills will become the fourth member of the company’s Corporate Executive
Committee on 1 January 2009. Lester Mills will be responsible for global marketing and sales,
and will strengthen the existing team of Rolf Nyfeler, chief executive officer, Daniel Erne,
chief technology officer, and Michael Hüsler, chief financial officer.

Lester Mills, aged 49, who has dual British and Swiss nationality, studied chemistry at the University of Cambridge, England, and then obtained his Ph.D. at the University of East Anglia, England. In the course of his professional career, he added to his specialist
qualifications with an MBA from the State University of New York, Albany, NY, USA.

Lester Mills has extensive international industrial experience from his previous work in the USA and Switzerland. After starting his career as a research chemist at Lonza, he soon turned his attention to the commercial side of the business and had various management functions in marketing and purchasing with Genzyme, Roche Vitamins and DSM Nutritional Products. At present, he is director of sales at DSM Nutritional Products Europe,
Birsfelden, Switzerland.

Rolf Nyfeler, CEO of Bachem, commented: “In Lester Mills we have succeeded in attracting a highly qualified and internationally experienced professional to our company. Thanks to his earlier work with Genzyme, he already has detailed knowledge of our core business, the peptide market. In face of the increasing globalization and continuous growth of our business, we expect Lester Mills to bring a dynamic impetus to the newly created executive committee function for marketing and sales, and thereby contribute substantially to the further development of Bachem.”

With the creation of the new Corporate Executive Committee function, the marketing and sales unit at Bachem will be restructured and further expanded to take account of the sustained global interest and growing demand for its products and services.
