THE BOARD OF DIRECTORS’ PROPOSALS

Item 1. Election of the Chairman of the Meeting

The Board of Directors proposes that Erik Thimfors, lawyer at Setterwalls Law Firm, is elected as Chairman of the Meeting.

Item 6. Resolution on authorization for the Board of Directors to resolve on new issue of shares, warrants and/or convertibles

The Board of Directors proposes that the Meeting resolves to authorize the Board to, from the period until the next Annual General Meeting, on one or more occasions and with or without deviation from the shareholder’s preferential rights, resolve on new issue of shares, warrants and/or convertibles. Payment can be made in cash, issue in kind, by offset or otherwise subject to conditions. The number of shares issued pursuant to the authorization, as well as those that may be issued through the exercise of options and the conversion of convertible securities issued pursuant to the authorization, may not exceed the number of shares permitted under the Articles of Association. In the event of a deviation from the shareholders' preferential rights, as well as in the event of payment in kind, the new issue shall be made on market terms with a customary market-based discount on the subscription price, where applicable. If the Board of Directors deems it appropriate in order to facilitate the delivery of shares in connection with a capital raise and/or broadening of the shareholder base, the new shares may be subscribed for by a bank or securities firm at a subscription price corresponding to the quota value, provided that an undertaking exists to contribute to the company a value corresponding to the difference between a market-based subscription price, less any customary market-based discount, and the quota value of the newly issued shares.

The Board of Directors, the CEO or the person appointed by the Board of Directors, shall be entitled to make such minor adjustments in the resolution that may prove to be necessary in connection with registration with the Swedish Companies Registration Office and Euroclear Sweden AB.

A valid resolution under this proposal requires the support of shareholders representing at least two-thirds of both the votes cast and the shares represented at the Meeting.
