                                                             3 August 2006

                          ("Lipoxen" or "the Company")

   Development and Manufacturing Agreement with the Serum Institute of India
                                    Limited

London, UK, 3rd August 2006 - Lipoxen PLC (AIM: LPX), a biopharmaceutical
company specialising in the development of differentiated biologicals, vaccines
and oncology drugs, today announced that it has entered into  a Development and
Manufacturing Agreement ("DMA") with the Serum Institute of India Limited
("SIIL").

Pursuant to the DMA, SIIL will develop the technology for the manufacture of
polysialic acid ("PSA") and its derivatives to the US Food and Drug
Administration ("FDA") standards on a commercial scale to meet the demands of
the Company's collaborative partners and for pre-clinical and clinical trials
purposes.



While the Company has made considerable progress in its pre-clinical lab scale
programmes, it does not have the infrastructure or financial capacity to
initiate a commercial-scale FDA compliant manufacturing facility. Pursuant to
the DMA, SIIL will provide Lipoxen with a unique source of polysialic acid
(biopolymer) according to Good Manufacturing Practices ("GMP") standards and
customized to Lipoxen's specifications which will allow clinical development of
Lipoxen's protein drug pipeline and continuous supply of the biopolymer to the
Company's current and future collaborative partners.



SIIL is widely recognised as a world-class contract manufacturer and is able to
deliver a wide range of products and clinical assistance to the Company on a
market competitive basis. In particular, SIIL has developed a complete process
of fermentation, purification and manufacture of PSA and the DMA provides the
framework for this process to be taken forward to enable production on a
competitive commercial basis.



The terms of the DMA require the Company to make a single capital payment
against which SIIL has contracted to establish a fully functional FDA-compliant
PSA production facility in early 2007 in order to supply suitable quantities of
PSA both to the Company (in support of its ongoing pre-clinical programmes) and
to the Company's collaborative partners as certain product candidates move to
the clinical trials stage. Provision has also been made for the Company to
receive royalty payments from SIIL under certain circumstances.  The DMA further
provides for compensation to be payable to the Company in the unlikely case of
SIIL failing to meet its basic obligations under the agreement.  The term of the
DMA runs in parallel with that of a licensing agreement dated 16 December 2004
(as amended on 11 October 2005) between SIIL and Lipoxen Technologies Limited
(the wholly owned subsidiary of the Company) being for, effectively, an
indefinite term.



Accordingly, the DMA lies at the heart of the Company's strategy to bring its
(and its collaborative partners') product candidates to market at the earliest
date and the further collaboration with this globally leading producer is
considered pivotal to achieving that goal. The DMA establishes SIIL as the
Company's key contract manufacturing partner and represents a substantial
milestone in the continuing development of PolyXen(R), Lipoxen's patented
protein drug-delivery technology.
