Danaher Announces Recommended Tender Offer for Vision Systems Limited

Danaher Corporation announces that it has agreed with Vision Systems Limited (Vision) that Danaher will initiate a tender offer to acquire Vision for A$3.75 (US$2.79) per share, for an aggregate price of approximately US$520 million, including transaction costs and net of cash acquired.

The Board of Directors of Vision has unanimously recommended that the shareholders of Vision accept the offer in the absence of a superior offer. The offer will be subject to tender of a majority of the Vision shares (on a fully diluted basis) into the offer and certain other customary closing conditions. The transaction is expected to close during the fourth quarter of 2006.

Danaher and Ventana Medical Systems, Inc. have terminated their previously disclosed discussions regarding a potential cooperative effort to purchase Vision.

Danaher's Leica Microsystems pathology diagnostics business with its solid base of technologies, instruments, global reach and brand coupled with Vision's innovative and proprietary technologies would create a leading global supplier of innovative solutions serving the anatomical pathology market. Together Vision and Leica Microsystems would offer a complete line of specimen preparation and diagnostic instruments while offering the advanced chemistries critical to the future of pathology.

Founded in 1987 and headquartered in Melbourne, Australia, Vision has operations in Australia, the United States and the United Kingdom. Vision is a manufacturer and marketer of automated instruments including the Peloris™ rapid tissue processor and the Bond™-maX advanced staining system, as well as Novocastra™ antibodies and biochemical reagents for biopsy-based detection of cancer and infectious diseases.

H. Lawrence Culp, Jr., President and CEO of Danaher, said: "Vision has an attractive pathology diagnostics instrument and consumable product offering that fits very well with the growth strategy we are pursuing for our Medical Technology Platform. Specifically, we believe that Vision's strength in rapid tissue processing and workflow-optimized advanced staining systems will allow us to drive growth by offering customers both improved productivity and advanced diagnostic technologies for use in clinical pathology laboratories. The partnering of Leica's strong, global brand and Vision's innovative technologies creates a unique opportunity to provide creative solutions to the pathology diagnostic market."

Dr. James Fox, Managing Director of Vision Systems Limited said: "Vision's shareholders clearly benefit from this transaction and we also recognize that Danaher and Leica Microsystems provide a unique set of opportunities for our businesses to thrive and continue to grow. We are excited by this combination and look forward to capitalizing on the opportunity to better serve our customers and provide stimulating challenges for our professionals worldwide."
