Bayer determines EUR 98.98 as cash compensation per Schering share

Berlin, December 5, 2006

Squeeze-out of Schering’s minority shareholders
• Higher cash compensation due to reduced capital market returns
• Extraordinary Shareholders’ Meeting of Schering AG on January 17, 2007

Berlin/Leverkusen – Bayer plans to acquire the remaining outstanding shares of Schering AG – just under four percent of the share capital – by means of a squeeze-out. Employing this legally defined procedure, it is intended to pass a resolution at a shareholders’ meeting to exclude Schering’s minority shareholders from the company in return for adequate cash compensation. Their shares would then be transferred to the main shareholder, Bayer Schering GmbH. The squeeze-out resolution will be proposed to an Extraordinary Shareholders’ Meeting of Schering AG to be held in Berlin on January 17, 2007. The notice of the meeting, which was approved today by Schering’s Management Board and Supervisory Board, will be published shortly.

With the assistance of KPMG Deutsche Treuhand-Gesellschaft Aktiengesellschaft Wirtschaftsprüfungsgesellschaft, Bayer has determined the adequate cash compensation as EUR 98.98 per Schering share. This amount has been confirmed as adequate by Dr. Ebner, Dr. Stolz & Partner GmbH, the expert auditor chosen and appointed by the court.

The amount of the cash compensation is equivalent to the present value of the annual guaranteed dividend payments as determined by KPMG in September this year, amounting to EUR 3.62 net per share, to which Schering’s minority shareholders are entitled in the future under the domination and profit and loss transfer agreement. However, the cash compensation that has now been determined is higher than the compensation offer of EUR 89.36 per share announced pursuant to the domination and profit and loss transfer agreement, mainly because of the decline in capital market returns that has occurred since September 13, 2006.
