OC Oerlikon Board of Directors provisionally refuses Renova Industries’ applications for entry in share register

Pfäffikon SZ, Switzerland, 29 April 2008 - At its meeting today, the Board of Directors of OC Oerlikon Corporation AG, Pfäffikon, Switzerland, resolved to provisionally refuse applications of Renova Industries Ltd, Bahamas, for the entry of additional shares in the share register received on 10, 11 and 14 April 2008. The total volume of the shares affected by this decision makes up more than 10 per cent of the company’s share capital. In the view of the Board of Directors, the applications for entry in the register raise various ownership and merger control-related questions which have not yet been fully clarified. This means that there is not yet a sufficiently secure legal basis for entry in the share register. As soon as these remaining questions have been adequately clarified by the shareholders affected, the Board of Directors will take up the matter again.
