  Oxonica achieves important further performance validation for EnviroxTM and
                              commercial progress


Oxonica plc ("Oxonica"), a leading international nanomaterials group, today is
pleased to announce an important further validation of its EnviroxTM fuel borne
catalyst by Stagecoach Group plc ("(Stagecoach) as well as positive test results
and significant commercial progress in mainland Europe and Russia.

Stagecoach originally tested EnviroxTM in 2004 in an industry leading trial on
1300 vehicles split between the North-west of England and London over a 12 month
period.  The trial demonstrated fuel savings of more than 5% following which
Stagecoach adopted the product across its UK fleet. At the time of adoption, the
parties also agreed to carry out a validation trial to confirm continued product
performance within 3 years.

In the second half of 2007 a validation trial was conducted on more than 550
Stagecoach vehicles in the North-west of England. This trial has demonstrated a
statistically significant fuel saving of 4.3% after 3 months, which is
consistent with the results from the original 2004 trial at the same point.

Stagecoach has indicated that it is satisfied with the results and intends to
continue to use EnviroxTM across its 7,000 vehicle UK bus fleet.

Adrian Havlin, Stagecoach Group Technical Engineer said: 'Stagecoach is in the
front line of tackling climate change through a range of initiatives, from
biofuels and cleaner engines to the introduction of modern environmental
management systems. The use of EnviroxTM is part of our package of innovative
solutions to build a more environmentally sustainable business and encourage
greener travel'.

'Our vehicles have driven more than 700 million miles on EnviroxTM, and to
achieve a consistent result across a diverse fleet over 3 years testifies to the
robustness of the technology.  We are particularly pleased with the performance
of the product both in ultra low sulphur diesel and in blends containing
biodiesel, which are now in widespread use across our fleet'.

In addition to the successful Stagecoach validation trial, EnviroxTM has
achieved further positive test results and has made significant commercial
progress in mainland Europe and Russia:

*  A recently completed bus trial in Italy demonstrated fuel savings of 4.8% 
   after 3 months and 10.6% after 6 months.  Other trials in Germany on tour
   coaches and municipal mixed fleets have demonstrated savings of 5 to 8%.

*  Oxonica has recently completed an additional piece of work in collaboration 
   with Stagecoach at a major, independent, vehicle testing facility in the 
   UK that demonstrated reductions in particulate emissions of 18% after 3
   months.  An independent vehicle laboratory test in Italy also showed 
   reductions in particulate emissions of up to 19%.

*  Oxonica has recently concluded two major distribution deals for EnviroxTM in 
   Germany and Russia, both of which have already generated initial sales in 
   2008.

Dr Kevin Matthews, CEO of Oxonica said, 'The evidence for the performance of
EnviroxTM is becoming increasingly compelling at a time when the issues of
climate change and high fuel costs are becoming acute. This proven technology
offers the potential to make a real difference to carbon dioxide emissions
today. In the UK, reducing diesel fuel use by 5% will save 3 million tonnes of
carbon dioxide per year, and EnviroxTM can achieve this while, at the same time,
reducing the burden of high fuel costs on the transport sector'.

Richard Farleigh, Chairman of Oxonica said: 'The UK is committed to reducing
carbon dioxide emissions and huge sums are being invested in future technologies
that may be too little too late.  Action needs to be taken now and once again
Stagecoach has demonstrated its industry leadership in addressing environmental
issues through its use of EnviroxTM and continued support for trialling and
testing of the product. EnviroxTM clearly provides immediate benefits to the
environment while more than paying for itself through fuel savings.'
