Statement re Unsolicited Approach

In light of the recent share price movements the Board of Cyprotex (AIM: CRX) announces that it has received a highly preliminary and unsolicited approach regarding a potential offer for the Company.

It should be noted that there is no certainty that an offer will be forthcoming.

This announcement has been made without the consent of the party who made the approach.

In accordance with Rule 2.10 of The City Code on Takeovers and Mergers (the 'Code'), Cyprotex confirms that, as at the date of this announcement it had 178,957,188 ordinary shares of 0.01 pence each in issue.

Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the City Code on Takeovers and Mergers (the 'Code'), if any person is, or becomes, 'interested' (directly or indirectly) in 1% or more of any class of 'relevant securities' of the Company, all 'dealings' in any 'relevant securities' of the Company (including by means of an option in respect of, or a derivative referenced to, any such 'relevant securities') must be publicly disclosed by no later than 3.30pm (London time) on the London business day following the date of the relevant transaction. This requirement will continue until the date on which the offer becomes, or is declared, unconditional as to acceptances, lapses or is otherwise withdrawn or on which the 'offer period' otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an 'interest' in 'relevant securities' of the Company, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the Code, all 'dealings' in 'relevant securities' of the Company by the Company or by any of its respective 'associates', must be disclosed by no later than 12.00 noon (London time) on the London business day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose 'relevant securities' 'dealings' should be disclosed, and the number of such securities in issue, can be found on the Takeover Panel's website at www.thetakeoverpanel.org.uk.

'Interests in securities' arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in price or securities. In particular, a person will be treated as having an 'interest' by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Code, which can be found on the Panel's website. If you are in any doubt as to whether or not you are required to disclose a 'dealing' under Rule 8, you should consult the Panel.

If you are in any doubt as to the application of Rule 8 to you, please contact an independent financial advisor authorised under the Financial Services and Markets Act 2000, consult the Panel's website at www.thetakeoverpanel.org.uk or contact the Panel on telephone number +44 20 7638 0129; fax +44 20 7236 7013.
