PROPOSED RESOLUTIONS

Item 8 - Resolution on preferential right issue

The board of directors proposes that the Extra General Meeting resolves to increase the Company's share capital by a maximum of SEK 292,323.40 by, subject to the shareholders' preferential rights, an share issue of a maximum of 48,705,400 shares (the "Preferential Rights Issue").

The share issue shall be addressed to existing shareholders, pro rata their shareholding on the record date, who, with the support of their preferential rights, shall have the right to subscribe for shares. Each share in the Company entitles to one (1) subscription right and seven (7) subscription rights entitle to subscription for two (2) new shares.

The subscription price amounts to SEK 1.30 per share. The new shares will be subscribed for during the period 3 - 17 December 2020. The record date is 2 December 2020.

The Preferential Rights Issue is conditional on the Company receiving approval from the Swedish Financial Supervisory Authority (sw. Finansinspektionen) of a prospectus for the Preferential Right Issue.

Item 9 - Resolution on authorizing the board of directors to decide on an overallotment share issue

The board of directors also proposes that the Extraordinary General Meeting resolves to authorize the board of directors to, within six (6) months of the decision on the Preferential Rights Issue, on one occasion, and with deviation from the shareholders' preferential rights, decide on an overallotment of shares to the subscribers in the Preferential Rights Issue who did not receive full allocation therein. The board of directors shall then have the right to decide that the shares issued in the overallotment share issue shall be paid for in the form of cash payment or by setting-off claims against the Company. The issue price and other issue terms shall (in addition to the above) correspond to the terms of the Preferential Rights Issue. The board of directors' decision on the overallotment share issue may in total comprise a maximum increase of the Company's share capital of SEK 60,000 and a maximum of 10,000,000 shares.

The purpose of the authorization of an overallotment share issue and the reasons for deviating from the shareholders' preferential rights is to satisfy a possible oversubscription in the Preferential Rights Issue and thereby provide the Company with additional capital.

MAJORITY REQUIREMENT

A resolution in accordance with the board of directors' proposal under item 9 above requires that the resolution is decided by shareholders representing at least two thirds (2/3) of both the votes cast and the shares represented at the Extra General Meeting.

DOCUMENTATION

The complete proposal under item 8, a copy of the Company's annual report, the auditor's report and the board of directors report on significant events of the Company's financial position and the auditor's opinion on it will be available to the shareholders of the Company at the above address and on the Company's website www.attana.com no later than 2 weeks before the Extra General Meeting. The documents are also sent free of charge to the shareholders who request it from the Company and state their address.
