Resolutions proposed by the Board of Directors

Item 8 – Resolution regarding the allocation of the Company's profit in accordance with the adopted balance sheet.

The Board of Directors proposes that no dividend is distributed and that the retained profit shall be carried forward to the new accounts.

Item 10 – Resolution to amend the Articles of Association.

For the purpose of adjusting the limits for the share capital and the number of shares in the Articles of Association in light of the Board of Directors' proposal to authorise the Board of Directors to resolve upon a rights issue as set out in item 19 of the notice convening the Annual General Meeting, the Board of Directors proposes to amend § 4 and § 5 in the Articles of Association in accordance with the below. Further, the Board of Directors proposes that § 11 of the Articles of Association is amended so that a General Meeting, in addition to being able to be held in Gothenburg, may also be held in Stockholm.

Item 17 – Resolution on the approval of the remuneration report.

The Board of Directors proposes that the Annual General Meeting resolves to approve the Board of Directors' remuneration report.

Item 18 – Resolution to grant the Board of Directors the authority to resolve on an issue of new shares, either applying or disapplying shareholders' preferential rights.

The Board of Directors' proposal implies that the Board of Directors shall be authorised to, during the period until the next Annual General Meeting, resolve on new share issues, on one or several occasions, with or without deviation from the shareholders' preferential rights and that shares corresponding to maximum ten per cent (10%) of the Company's share capital as of the date for the first exercise of the authorisation may be issued. Further, the proposal implies that an issue may be made against cash payment, by set-off or by contribution in kind. In case of deviation from the shareholders' preferential rights, shares shall be issued on market terms. The purpose of the Board of Directors' proposal is to (i) enable the Company to completely or partially finance any future real property investments and/or acquisitions of real property companies/businesses by issuing new shares as payment in connection with agreements on acquisition of real property, alternatively to raise capital for such investments and/or acquisitions; and/or (ii) enable the Company to strengthen its financial position and/or create a larger liquidity buffer for financing commitments.

Item 19 – Resolution to grant the Board of Directors the authority to resolve on an issue of new shares, applying the shareholders' preferential rights.

The Board of Directors' proposal implies that the Board of Directors shall be authorised to, during the period until the next Annual General Meeting, resolve on new share issues, on one or several occasions, with preferential rights for the shareholders, for the purpose of strengthening the Company's financial position. The total number of shares that may be issued by virtue of the authorisation shall amount to the number of shares that corresponds to issue proceeds of approximately SEK 10 billion. Other terms and conditions for the new share issue shall be determined by the Board of Directors.

Item 20 – Resolution to grant the Board of Directors the authority to resolve on acquisitions and transfers of the Company's own shares.

The Board of Directors' proposal implies that the Board of Directors shall be authorised to, during the period until the next Annual General Meeting, resolve on acquisition on one or several occasions, of the Company's own shares provided that the Company after each acquisition will not hold more than ten per cent (10%) of all the shares in the Company, and to transfer all of the Company's own shares with deviation from the shareholders' preferential rights. The objective of the Board of Directors' proposal is to allow the Company to adapt its capital structure to its capital needs from time to time and thereby contribute to an increased shareholder value, and/or to transfer own shares as payment in order to completely or partially finance any future real property investments and/or acquisitions of real property companies/businesses or by using own shares as payment in connection with agreements on acquisition of real property, alternatively to raise capital for such investments and/or acquisitions. This objective does not allow the Company to trade with its own shares for the short-term purpose of making a profit.

Item 21 – Resolution to reduce the share capital by way of cancellation of own shares.

The Board of Directors proposes that the Annual General Meeting resolves to reduce the Company's share capital by an amount of SEK 8,665,500 by way of cancellation of the 17,331,000 own shares held by the Company as of the date of this notice. The reduction amount shall be allocated to unrestricted equity.

The resolution to reduce the share capital by way of cancellation of own shares is conditional upon the Board of Directors utilising the authorisation proposed to be resolved by the Annual General Meeting in accordance with item 19 of the notice convening the Annual General Meeting.

The resolution to reduce the share capital may be carried out without obtaining an authorisation from the Swedish Companies Registration Office, since the resolution will not be executed unless the Company simultaneously carries out a rights issue by means of the Board of Directors' exercise of the authorisation proposed to be resolved upon by the Annual General Meeting as set out in item 19 of the notice convening the Annual General Meeting. This entails that the share capital, after the rights issue, will increase by an amount exceeding the amount that the share capital is being reduced with as set out above. Combined, these measures entail that neither the Company's restricted equity nor its share capital is reduced as a result of the cancellation of own shares.

At the request of the Nomination Committee, Castellum shall provide the Nomination Committee with personnel resources, such as secretarial services, in order to facilitate the work of the Nomination Committee. Furthermore, the Company shall bear reasonable costs, e.g. for external consultants, which the Nomination Committee deems necessary in order to fulfil the Nomination Committee’s assignments.

Composition of the Nomination Committee

1. The Nomination Committee shall be appointed by the Chairman of the Board of Directors contacting the four largest shareholders (in terms of voting rights), registered in the share register kept by Euroclear Sweden AB as per the last business day in August each year or the largest otherwise known shareholders, and asking them to appoint one member each to the Nomination Committee. Should such a shareholder not wish to appoint a member, the next largest registered shareholder in terms of voting rights or otherwise known shareholders shall be asked, and so on.
2. A major shareholder or group of shareholders shall be entitled to appoint one but not more members of the Nomination Committee. If the Chairman of the Board of Directors of the Company is employed by or is otherwise not independent in relation to one of the shareholders that is entitled to appoint a member of the Nomination Committee, that shareholder shall not have the right to appoint a member. In such an event, the Chairman of the Company's Board of Directors shall then be deemed to be appointed by that shareholder.
3. The appointed members, together with the Chairman of the Board of Directors of the Company, who is the convening member, shall constitute the Nomination Committee. The names of the members of the Nomination Committee and the names of the shareholders by whom they have been appointed shall be announced no later than six months prior to each Annual General Meeting.
4. Unless the members of the Nomination Committee have agreed otherwise, the member appointed by the largest shareholder shall be the Chairman of the Nomination Committee. The Chairman of the Nomination Committee shall have the casting vote in the event that votes are equal.
5. A member of the Nomination Committee shall, before accepting the assignment, carefully consider whether any conflict of interest or other circumstance exists that makes it inappropriate to serve on the Nomination Committee.
6. The members of the Nomination Committee are subject to a confidentiality obligation regarding Castellum's business and this obligation shall, at the Company's request, be confirmed by the members by signing a confidentiality undertaking.

Changes to the composition of the Nomination Committee

1. If, more than two months prior to the Annual General Meeting, a new shareholder passes (in terms of voting rights) one of the shareholders in the list of shareholders that have appointed a member of the Nomination Committee, this shareholder may contact the Chairman of the Nomination Committee and request the appointment of a member of the Nomination Committee. In such an event, the member appointed by the shareholder with the lowest number of votes shall resign from the Nomination Committee.
2. If a shareholder who has appointed a member of the Nomination Committee has disposed a significant proportion of its shareholding, so that it is no longer one of the four largest shareholders (in terms of voting rights) more than two months prior to the Annual General Meeting, the appointed member shall make its seat available. The Chairman of the Nomination Committee shall then contact the largest shareholder in terms of voting rights who has not previously been offered a seat. If the latter does not wish to appoint a member, the matter shall be passed on to the next shareholder in line, and so on.
3. Shareholders who have appointed a member to the Nomination Committee shall be entitled to dismiss such member and appoint a new representative as a member of the Nomination Committee.
