Notice of extraordinary general meeting in Alligator Bioscience AB

The shareholders of Alligator Bioscience AB, Reg. No. 556597-8201 ("Alligator"), are invited to the extraordinary general meeting to be held on Monday 8 November 2021.

In light of the ongoing Covid-19 pandemic and in order to reduce the risk of infection spreading, the board of directors has decided that the meeting will be held only by advance voting (postal vote) in accordance with temporary legislation. This means that the meeting will be conducted without the physical presence of shareholders, proxies or external parties and that shareholders' exercise of voting rights at the meeting can only take place by shareholders voting in advance in the order prescribed below. Information on the resolutions passed by the meeting will be published on Monday 8 November 2021, as soon as the outcome of the advance voting is finally compiled.

TRUSTEE-REGISTERED SHARES

Shareholders whose shares are trustee-registered in the name of a bank or other trustee must, to be able to exercise their voting rights at the meeting by advance voting, request the trustee to register their shares in their own name with Euroclear Sweden AB (so called "voting rights registration"). Such voting rights registration must be implemented by the trustee no later than as of Tuesday 2 November 2021. Accordingly, shareholders must well in advance before this date notify their trustee of their request of such voting rights registration.

not) and who have applied for subscription of shares without exercise of subscription rights and if allotment to these cannot be made in full, allotment shall be made pro rata in relation to the number of subscription rights that each and every one of those, who have applied for subscription of shares without exercise of subscription rights, have exercised for subscription of shares;

Item 8: Resolution on authorization for the board of directors to resolve on new issues of ordinary shares

In order to enable new issues of ordinary shares as guarantee compensation to those that have entered into guarantee undertakings in order to secure the rights issue of ordinary shares as described below (the "Guarantors"), the board of directors proposes that the extraordinary general meeting resolves to authorize the board of directors, up until the next annual general meeting, at one or several occasions, with deviation from the shareholders' preferential rights, and with or without provisions regarding set-off or other provisions, to resolve on new issues of ordinary shares to the Guarantors. Upon exercise of the authorization, the subscription price shall correspond to 90 per cent of the volume-weighted average price (VWAP) for the Company's ordinary share on Nasdaq Stockholm during the subscription period in the rights issue of ordinary shares resolved by the board of directors on 7 October 2021, and which is proposed for approval under item 7 on the agenda of the

extraordinary general meeting (i.e. during the period 12 – 26 November 2021), however, no lower than the subscription price in the rights issue.

The purpose of the authorization and reason for the deviation from the shareholders' preferential rights is to be able to carry out new issues of ordinary shares as guarantee compensation to the Guarantors. The number of ordinary shares that may be issued through the authorization shall not exceed the total number of ordinary shares that corresponds to the agreed guarantee compensation that the company shall pay to the Guarantors.

The resolution on authorization in accordance with this proposal presupposes and is conditional on the extraordinary general meeting resolving to approve the board of directors' resolution of 7 October 2021 on rights issue of ordinary shares in accordance with the board of directors' proposal to the extraordinary general meeting.

The company's CEO shall be authorized to make such minor formal adjustments of the resolution as might be necessary in connection with registration with the Swedish Companies Registration Office.
