Acquisition

Tristel PLC 29 August 2006 For release 29 August 2006 Tristel Plc Technology Acquisition Agreement with IVC Limited, New Zealand Tristel plc ('Tristel'), the chlorine dioxide specialist that supplies infection and contamination control products to healthcare and institutional establishments and the pharmaceutical and food processing industries, announces that it has entered into a technology acquisition agreement with IVC Limited, ('IVC'). IVC is Tristel's New Zealand distributor and its principal shareholder is Mark Fraundorfer, an internationally renowned Urologist. Under the terms of the agreement IVC transfers to Tristel the design and patent rights to two inventions which it has created to work specifically with Tristel's chlorine dioxide chemistry. The inventions are a sterilizing tray system which enables single use decontamination of endoscopic equipment and a hygiene work station which enables Tristel's highly effective sporicidal chemistry to be easily applied to floors and walls in high risk wards and departments of hospitals. IVC has funded the design and development process to date and transfers the intellectual property created in return for unspecified future royalties. Commenting upon the agreement, Paul Swinney, Chief Executive of Tristel, said: 'Outside of the most advanced healthcare markets, where endoscopes are mainly processed in sophisticated and costly automated machines, the majority of endoscopes are disinfected in basic trays and sinks. These can only hold disinfectant liquids that have to be used repeatedly for many instruments over a period of many hours or even days. 'The Tristel tray system, combined with Tristel's novel burstable sachet, Tristel Fusion, enables the disinfectant to be used once and to be dedicated to one instrument only. 'This achieves one of the key features of the most sophisticated endoscope reprocessing machines at a fraction of their cost, and will help Tristel penetrate many overseas markets with its chlorine dioxide disinfectants.'
