The Board has noted the recent fall in the Company's share price and wishes to
advise the Market that it is not aware of any reason for the fall. Current
trading is in line with both the Board's and the Market's expectations. As
indicated by the recent announcements of a patent grant, two development grant
awards and a licence agreement for bio-markers of Alzheimer's disease, the
Company continues to make progress and the Board looks forward to updating the
Market with further progress in due course.
