Physiomics plc - Agreement

For release: 07:00 - 15th February 2007

                                  VALIRX PLC                                   

                          ("ValiRx" or the "Company")                          

                           Physiomics plc Agreement                            

ValiRx (AIM: VAL), the cancer therapeutics company, today announces that it has
signed a new agreement with Physiomics plc ("Physiomics") (AIM: PYC), the
European systems biology simulation company, to use Physiomics' In Silico
simulations of cellular processes to reduce the development time and costs
associated in identifying new therapeutic compounds for the treatment of
cancers.

ValiRx's subsidiary, Cronos Therapeutics Limited - developers of GeneICE - will
be the first ValiRx entity to use Physiomics' technology.

It is anticipated that by coupling GeneICE's ability to act on genes directly
with the predictive capacity of Physiomics' modeling expertise in biological
systems, it will be possible to optimise the development of possible therapies
in terms of time and cost.

Dr Paul Harper, a Director of Physiomics, said:

"We look forward to deploying our simulation models to help predict and select
the optimal targets for ValiRx's break-through GeneICE technology."

Dr Satu Vainikka, CEO of ValiRx, added:

"Correct target selection at the outset is critical to reducing the time spent
- and often lost - in the clinical trial process. We view our relationship with
Physiomics as important."

The primary concentration of the initial programme will be to investigate the
process of Apoptosis (the natural process of programmed cell death and
turnover) - a process that is frequently disrupted in Cancers.

About Physiomics plc

Physiomics plc (AIM:PYC) is a computational systems biology services company
applying simulations of cell behaviour to drug development to reduce the high
attrition rates of clinical trials. As 80-90 per cent. of all clinical drug
candidates fail to reach the market, estimates show that an overall ten per
cent. improvement in success rates could reduce the cost of one drug's
development by as much as $242 million, from the current estimate of around
$800 million.

Physiomics is currently focused on optimising the design of cancer clinical
trials as a service to major pharmaceutical companies. Physiomics has a major
collaboration with Bayer Technology Services GmbH to develop globally clinical
response prediction services using both companies' proprietary technologies and
mathematical cell models, including the SystemCell® technology developed by
Physiomics. In June 2005, Physiomics became a distributor of Bayer's KSim®
product for understanding the way pharmaceuticals are distributed round the
body. Physiomics, based in Oxford, UK, was founded in 2001, and floated on AIM
in 2004. For further information, please visit www.physiomics-plc.com
