                                    Press Release

  Natural products drug company Hypha Discovery signs deal with Domainex to
            support its research programme on novel oncology drugs

London and Cambridge, UK, 14th May 2009. Domainex Ltd today announced that it
is helping natural products company Hypha Discovery Ltd to develop drugs based
upon a number of innovative leads that are active against tumour cell lines.


The collaboration will bring together Hypha’s extensive expertise in natural products
lead discovery and Domainex’s outstanding capability to optimise drug leads using its
LeadBuilder platform technology and experienced medicinal chemistry team. Hypha
has identified a pipeline of novel natural products that have significant activity against
tumour cell lines - led by the fully synthetic anti-cancer chemical series HD148, which
was inspired by compounds produced by the fermentation of a tropical mushroom.
Domainex has been supporting Hypha’s drug discovery programme and has
successfully developed a series of low molecular weight anti-tumour agents based
upon the structure of these natural products. The objectives of the project will be for
Domainex to deliver to Hypha an advanced lead molecule, and subsequently a
clinical candidate.


Dr Liam Evans, Chief Executive Officer of Hypha Discovery Ltd, said: “Having
discovered a series of anti-cancer compounds with such clear scope for chemical
optimisation, it was important to us to find the right medicinal chemistry partner to
drive the project forward. In only three months of working on the synthetic
programme, Domainex have already increased the potency of the series fifty-fold,
while also improving solubility. We’re delighted to have linked up with such an expert
group and look forward to continued success in the development of the HD148
programme, as well as our follow-on oncology projects. ”


Dr Eddy Littler, Chief Executive Officer of Domainex, commented: “Domainex is very
happy to have been selected as Hypha’s partner to work on such an exciting lead
series, which demonstrates the value of the chemical novelty in Hypha’s
MycoDiverseTM library. We look forward to providing the molecules that they need to
take their project forward. The collaboration demonstrates our capability to support
companies with leads identified from natural products, and is further validation of
Domainex’s position as the drug discovery partner of choice for biotech and
university groups. Companies like Hypha, which are investigating the therapeutic
potential of natural products as drugs, or as chemical leads, represent a highly
innovative and important component of the biotechnology industry.”

Editors Notes
About Hypha Discovery Ltd.
   •   Hypha is a privately held pharmaceutical discovery company uniquely placed to
       discover novel drug-leads from a collection of 2,500 highly diverse mushroom fungi
       (the basidiomycetes), much of it from tropical rainforest.
   •   The company is expert in discovering bioactive compounds from fermentations of the
       collection, with a high proportion of novelty (about 50%) which is unusual for modern
       natural products discovery.
   •   Hypha has internal research programmes targeted for antibiotic and anticancer
       compound discovery. Currently five separate anti-cancer projects are being
       progressed, led by the HD148 programme – a fully synthetic series of compounds
       that kill tumour cells.
   •   Hypha is seeking collaborations with companies with a need for novel active
       compounds for pharmaceutical development, as well as those interested in novel
       enzymes for biofuel applications and other macromolecules.
   •   Hypha also provides contract services to pharmaceutical and biotechnology
       companies, for compound purification and identification (e.g. manufacturing
       impurities, natural products from various sources), and biological assays (anticancer,
       antibacterial and antifungal).

About Domainex
   •   Domainex uses unique and proprietary technologies to resolve common bottlenecks
       facing the pharmaceutical and biotechnology industries in the post-genomic era.
       Major discovery 'gaps' exist between the vast amount of genomic information that is
       now available, the accessibility of the corresponding proteins for use in target
       validation and drug discovery, and the identification of robust hits in a cost effective
       manner. Founded in 2002, Domainex is a privately owned company with laboratories
       in Cambridge, England, and offices in the London Bioscience Innovation Centre.
   •   Domainex has developed a number of platform technologies specifically aimed at
       enabling biotech or university groups who have exciting new drug targets. Its
       Combinatorial Domain Hunting (CDH) technology will deliver protein constructs that
       are soluble, stable, and produced in high-yield - thereby opening up the path to high
       throughput screening, structural biology, or antibody production. Domainex has also
       developed LeadBuilder - a virtual screening approach for targets which is specifically
       aimed at identifying hit molecules that are ideally suited for further development. The
       experienced medicinal chemistry team has a proven track record in supporting

biotech or university groups by providing expertise to take hit compounds through
    lead optimisation and on to candidate selection. Several compounds arising from
    these collaborations are currently in clinical evaluation.
•   Domainex works with clients on a fee-for-service basis. In 2008, the company
    secured investment to establish its own internal drug discovery pipeline based upon a
    number of targets in oncology. These targets are being progressed using Domainex’s
    platform technologies.
