                                  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.'
