Jena (Germany) — Management Board and Supervisory Board of CyBio AG (Deutsche Börse, General Standard, ISIN DE005412308) today decided to submit the proposal to the Shareholder’s Meeting on April 27, 2012, to authorize the Management Board to apply for withdrawing from the listing of CyBio AG shares on the Regulated Market at Frankfurt Stock Exchange and thus to terminate the listing of the shares of the Company at the stock exchange. Main shareholder Analytik Jena AG, Jena, agreed with this resolution.

Management Board is to assign an independent audit firm to determine the fair Company value. Within the context of the delisting, main shareholder Analytik Jena AG, Jena, will make an offer to the minority shareholders to purchase their shares against compensation according to the appropriate value determined by the audit firm.

The offering will be made under the preceding condition, that the Shareholder’s Meeting will authorize the Management Board to apply for the withdrawal from the listing, that Frankfurt Stock Exchange will accept the request and that the withdrawal of the listing will be announced accordingly.
