                         OXFORD CATALYSTS GROUP PLC

                   ('Oxford Catalysts' or 'the Company')

                          Development Contract: Steam

Oxford Catalysts Group PLC, the leading catalyst innovator for clean fuels, is
pleased to announce that it has progressed to a nine-month prototype development
program under contract with Proventec PLC ('Proventec'), a provider of
specialist steam cleaning technologies. This follows the successful completion
of an evaluation phase of the Company's technology by Proventec, pursuant to a
contract signed in February 2006. The agreement has a value to Oxford Catalysts
of up to £100,000, and provides for future licensing of the Company's technology
to Proventec for use in the steam cleaning market.

Oxford Catalysts has developed a unique catalytic method for the production of
steam directly from a liquid fuel, instantaneously starting from room
temperature. This technology dispenses with the need for a boiler, power cables,
external heat source or generator in a compact, safe and portable way. Both
Oxford Catalysts and Proventec recognise that the Company's technology has
direct application in the fast-growing markets for industrial steam cleaning,
including street cleaning, food processing, packaging plants and hospitals,
enabling mobile applications that are not currently feasible.

Roy Lipski, Chief Executive of Oxford Catalysts, said:

'This is a significant step for us as a company, allowing us to further the
commercialisation of our steam generation technology. We are delighted to be
working with Proventec on applying this technology to the industrial steam
cleaning market where it could become an important enabler for mobile and
portable steam cleaning applications. This program represents the successful
completion of a key milestone in the development of Oxford Catalysts' steam
generation technology. It demonstrates our commitment to delivering on our
commercialisation strategy that is designed to realise the substantial licensing
revenue potential of our broad portfolio of technologies.'

David Chestnutt, Chief Executive of Proventec, said:

'We are extremely excited about the commercial potential for this unique method
of steam generation. As the leading provider of steam cleaning, we believe that
this development will open new markets for use of steam as a cleaning and
disinfectant medium. We are pleased to be working with Oxford Catalysts and look
forward to bringing this technology to the market.'

Notes to Editors

Oxford Catalysts Group plc, the leading catalyst innovator for clean fuels,
designs and develops specialty catalysts for the generation of clean fuels from
both conventional fossil fuels and certain renewable sources such as biomass.
Its patent-pending technology is the result of 19 years of research at the
University of Oxford's prestigious Wolfson Catalysis Centre, headed by Professor
Malcolm Green, one of the world's most respected inorganic chemists. Oxford
Catalysts was founded by Professor Green and Dr Xiao in October 2004 and was
admitted to trading on the AIM market of the London Stock Exchange on 26th April
2006, having raised £15m before expenses from a solid base of institutional
investors.

Oxford Catalysts' strategy is to license its catalysts for commercial
application by entering into co-development partnerships with leading
manufacturers, producers and suppliers in the petroleum, petrochemicals, fuel
cells, biogas, steam applications and catalysis markets.

Oxford Catalysts has two key platform technologies. The first is for a novel
class of catalysts made from metal carbides which, for certain reactions, can
match or exceed the benefits of traditional precious metal catalysts at a lower
cost. Applications of these metal-carbide catalysts include the removal of
sulphur from crude oil fractions (known as hydro-desulphurisation or HDS), the
conversion of natural gas or coal into virtually sulphur-free liquid fuels via
the Fischer-Tropsch reaction (known as the GTL and CTL processes respectively),
and the transformation of biogas (waste methane) into syngas - the building 
block of liquid fuels.

The second platform relates to chemical reactions involving a liquid fuel
containing an alcohol (such as methanol), hydrogen peroxide and water. The
company's novel catalyst can be used to release hydrogen gas from this liquid
fuel, instantaneously starting from room temperature. This groundbreaking
hydrogen-on-demand technology has the potential to significantly accelerate the
commercial adoption of fuel cells in the portable and other mobile markets, by
providing the much needed source of cheap, safe transportable hydrogen.

Another of the company's catalysts can be used to produce superheated steam
(800c+) from the above fuel, instantaneously starting from room temperature.
Such portable high-temperature steam could have important applications in a
broad range of markets, from cleaning and disinfecting, to motive power and
electricity generation.

About Proventec

Proventec is a specialist and innovative provider of steam cleaning and coatings
technologies. The Company was formed as a result of the reverse takeover of
InnoCleaning Magma Holdings BV and OspreyDeepClean Limited, a group of fire
retardant coatings and specialist steam cleaning businesses, by Flintstone
Technologies plc in August 2005.

Proventec provides solutions to a number of markets including the food retail
and preparation market, hospitality industries, and healthcare which includes
hospitals and suppliers of hospital equipment, transport infrastructure,
construction materials and consumer products. The cleanings solutions are
designed to target and combat the spread of common food bacteria and HAI
(Hospital Acquired Infections), including MRSA.
