Due to the Ordinance on Measures to Combat the Coronavirus (COVID-19) issued by the Swiss Federal Council it is not permitted to hold this year's Ordinary Shareholders Meeting in the usual form, i.e. with the shareholders participating in person. That is why the Board of Directors has resolved in accordance with Art. 6b of the said Ordinance, that the shareholders may exercise their rights exclusively through the independent proxy by way of written or electronic instruction and power of attorney.

The Board of Directors regrets these extraordinary restrictions and looks forward to your par-ticipation in person in the Ordinary Shareholders' Meeting 2021.
