The remuneration report also includes information on remuneration to the Company's CEO.

Proposal for resolution on authorisation for the Board to resolve on issues of new shares (item 14)

The Board of Directors proposes that the AGM resolves to authorise the Board of Directors to, for the period until the next AGM on one or several occasions, decide on the issue of new shares corresponding to a maximum of ten (10) per cent of the Company's share capital with or without deviation from the shareholders' preferential rights. Furthermore, the proposal entails that an issue may be made against cash payment, by set-off or by contribution in kind. In the case of deviations from the shareholders' preferential rights, the shares will be issued at market terms and conditions.

The resolution to authorise the Board of Directors to resolve on issues of new shares requires the support of shareholders who represent at least two thirds (2/3) of the cast votes as well as the shares that are represented at the meeting.
