The Board of Proteome Sciences has noted the recent movement in the Company’s share price and that they are not aware of any reason for the share price increase.

In the trading update released on 21 December 2007, the Board reported that it continued to view future prospects for TMT® commercialisation with increasing confidence, with the related licence negotiations expected to be concluded in early 2008. This remains the case and the Company will issue a further update on licence negotiations in due course.
