Ad hoc: Board of Directors announces stock buyback to service share option plans On December 20, 2006, the Board of Directors of Wincor Nixdorf AG passed a resolution for the repurchase of up to 166,390 of the company's shares (constituting up to 1.01% of the current capital stock) via the stock exchange. The resolution is based on the corresponding authorization issued by the Annual General Meeting of Shareholders for the repurchase of own equity instruments in an amount of up to 10% of capital stock. The purchase price per share (excluding ancillary costs of purchase) shall deviate by no more than 5 per cent in either direction from the average share price at the closing auction of XETRA trading on the Frankfurt Stock Exchange for the final 10 trading days prior to the purchase of the shares. The repurchased shares are to be used for the purpose of settling obligations arising from share options already issued or to be issued to members of the Board of Directors, other managers or staff members.
