3M and Biotrace International PLC announced an offer to acquire the entire issued and to be issued share capital of Biotrace International PLC, a Bridgend, UK-based manufacturer and supplier of industrial microbiology products whose shares are listed on the London Stock Exchange. The board of Biotrace International has recommended the offer to Biotrace International's shareholders.

The offer values Biotrace International shares at approximately £52 million, or $98 million.

3M has offered 130 pence, approximately $2.46, per Biotrace International share. Under the terms of the offer, Biotrace International shareholders will retain the right to receive the interim dividend, announced on Sept. 6, 2006, of 0.55 pence per Biotrace International share for the six months ended June 30, 2006.

The board of directors of both companies has approved the transaction. The transaction is expected to close in the fourth quarter 2006, subject to customary closing conditions, regulatory approvals, and obtaining the requisite Biotrace International shareholder acceptances.

3M believes that Biotrace International offers a strong strategic fit and complementary product offering with 3M through its established position in providing hygiene monitoring and microbiological tests to the food, beverage and dairy sectors.

"We believe that this offer represents excellent value for Biotrace International's shareholders and a unique opportunity to accelerate the Company's expansion into new markets. Biotrace International's expertise in industrial microbiology combined with 3M's greater scale and global reach will create value enhancing opportunities for all stakeholders," said Chuck Kummeth, division vice president, 3M Medical Division.
