Authorization for over-allotment issue

The general meeting resolved to authorize the board of directors, for the period until the end of the next annual general meeting, to resolve on one or more occasions, with deviation from the shareholders' preferential rights, on a new issue of shares to enable over-allotment in the Rights Issue.

The purpose of the authorization is to ensure full allotment to investors who have entered into subscription commitments without preferential rights in the Rights Issue. The authorization may only be used if the Rights Issue is fully subscribed. A maximum of 66,000,000 new shares may be issued under the authorization, and the terms and conditions of any over-allotment issue shall be the same as in the Rights Issue, whereby the subscription price shall correspond to the subscription price in the Rights Issue.
