Notes to editors:

§ Bioquell is a UK-headquartered, international technology company with two divisions:

o Bio-decon which sells specialist bio-decontamination products and services into the Healthcare, Life Sciences and Defence sectors, with most of its revenues generated from overseas customers; and

o TRaC which provides specialist Testing, Regulatory and Compliance services, which are largely governed by regulations, to UK corporates.

§ Bioquell's bio-decontamination technology is principally based around hydrogen peroxide vapour - which is highly efficacious at eradicating micro-organisms such as bacteria and viruses at room temperature - and is subsequently broken down using specialist catalysts to water vapour and oxygen at the end of the bio-decontamination process.

§ Bioquell's bio-decontamination technology:

o is used to eradicate "superbugs" from hospitals; independent scientific research has demonstrated that 'bioquelling' hospital equipment and facilities reduces the rates of hospital acquired infection;

o is used by bio-pharmaceutical, biotechnology and research institutions to provide sterile equipment and/or sterile working environments;

o has been selected by the United States Department of Defense for the JSSED programme to decontaminate sensitive equipment against biological and chemical warfare agents;

o is used in other sectors where bioburden can create significant problems including, for example, the food industry; and

o also comprises specialist filtration technology including peroxide catalysis and chemical, biological, radiological and nuclear ("CBRN") filtration systems used principally in the defence sector.

§ Bioquell currently has overseas operations in the USA, France, Ireland and Singapore.

§ TRaC sells its specialist services to the product development departments of a broad range of companies, principally based in the UK, with a particular focus on aerospace, military and telecoms clients.
