Collaboration Agreement

Provexis PLC 12 September 2005 PROVEXIS PLC ('Provexis' or the 'Company') COLLABORATION AGREEMENT FOR CROHN'S DISEASE TECHNOLOGY Exercise of right to assign intellectual property from University of Liverpool Provexis, the nutraceutical company that develops scientifically-proven functional and medical foods, is delighted to announce that it has entered into a collaboration agreement with a leading clinical nutrition company ('the Company'). Provexis is currently developing a proprietary bioactive extract from the Plantain (part of the banana family) which is designed to extend remission in patients suffering from Inflammatory Bowel Disease (IBD). IBD has two forms, Crohn's Disease and Ulcerative Colitis, both are chronic inflammatory diseases of the digestive tract which, combined, affect approximately 1 in 400 in the western world countries. Under the terms of the collaboration agreement, Provexis and the Company will develop a medical food product incorporating this bioactive extract. It is intended that the food product will enter clinical trials in 2006 on patients suffering from Crohn's disease. Crohn's Disease is currently incurable with the primary goals of treatment being control of the inflammation, the relief of symptoms, addressing nutritional deficiencies and the extension of remission time. The Company will be responsible for the formulation, manufacture and packaging of the medical food product to be used in the full clinical trial and will have the option of securing an exclusive negotiation period after the trial. The negotiation period would give the Company the rights to be the first company to pursue the manufacturing and distribution rights for the product. However, Provexis is not obliged to enter into an agreement with the Company for these rights and furthermore, all intellectual property, including the industrial formulation of the medical food product, is wholly-owned by Provexis. In addition, following successful pre-clinical studies on this medical food treatment by the University of Liverpool and Provexis, Provexis has exercised its right to the assignment of the intellectual property from the University of Liverpool to a new Provexis subsidiary in which the University will be a minority shareholder. The specific components in Plantain with this therapeutic potential were discovered by Professor Jon Rhodes, based in the Department of Medicine at the University of Liverpool and an Honorary Consultant Gastroenterologist at the Royal Liverpool University Hospital. Dr Stephen Franklin, CEO of Provexis, commented: 'This is another significant milestone in the development of Provexis. This collaboration is an important validation of the strength of the Provexis technology pipeline.'

Functional foods are foods such as Benecol and Flora pro.activ that contain physiologically active food components and provide health benefits beyond basic nutrition. Medical foods are administered to patients by a physician for the dietary management of specific diseases. In June 2005 the Company joined AIM via a reverse takeover by Nutrinnovator. Nutrinnovator brings with it a technology pipeline as well as marketing, selling and business development skills. Provexis was formed in December 1999 by the life-science subsidiary of the venture-management company, ANGLE plc. In January 2000, Provexis entered into a new technology option agreement with Rowett Research Services Ltd. (RRS), the commercial subsidiary of the Aberdeen based Rowett Institute, and this option was exercised in November 2001. Provexis' agreements with RRS have provided it with the intellectual property rights pertaining to its lead product, Fruitflow. Provexis continues to have strong links with the Rowett Institute, which provides the company with R&D facilities, human trials and, potentially, new technologies. IBD - Technical Researchers at the University of Liverpool have recognised that IBD may represent an altered response to normal intestinal microbes In particular, they believe there is a possibility that apparently non-pathogenic 'harmless ' bacteria can cause inflammation if they penetrate the intestinal mucus and associate themselves with the lining cells of the intestine. The researchers have characterised the adherence of Inflammatory Bowel Disease related bacteria to carbohydrate structures on the lining of the intestine and found that the adhesion of such bacteria to cell surfaces can be blocked by some, but not all, complex carbohydrates. In particular, they found that specific types of soluble fibre, extracted from Plantain, were particularly effective for preventing bacterial adhesion and accordingly may have efficacy for preventing or treating IBD. They believe that the soluble fibres may either mimic or compete with bacterial receptors, thus preventing bacterial recruitment and subsequent inflammation. This discovery has led Provexis to believe that a Plantain--based formulation (as developed by chemists at Provexis and tested at the University of Liverpool) could underpin a new medical food treatment for extending remission time in patients with IBD. The medical food product is anticipated to enter a two-site clinical trial on patients with Crohn's Disease in Summer 2006.
