A. MATTERS ON THE AGENDA OF THE EXTRAORDINARY GENERAL MEETING

6. Resolution to amend the Articles of Association of the Company

The Board of Directors proposes that the extraordinary general meeting would resolve to amend section 1§ of the Articles of Association concerning the Company name and the corporate seat of the Company. According to the proposal, the amended section 1§ of the Articles of Association concerning the Company name and the corporate seat would in its entirety read as follows:

1§ Name and Corporate Seat of the Company

"The name of the Company is Ahtium Oyj and its domicile is Espoo. The parallel trade name of the Company in English is Ahtium Plc."

The Board of Directors further proposes that, provided the corporate seat of the Company is amended in accordance with the proposal by the Board of Directors, the extraordinary general meeting would resolve to make an amendment to the third paragraph of section 10§ of the Articles of Association concerning the venue of the general meetings, which after the amendment would read as follows:

10§ Convening the General Meeting (third paragraph)

"The General Meeting shall be held either in the corporate seat of the Company or in Helsinki."

7. Resolution to authorise the Board of Directors to resolve on share issue and the issuance of special rights entitling to shares

The Board of Directors proposes that the extraordinary general meeting would resolve to authorise the Board of Directors to decide on the issuance of new shares and the transfer of the Company's own shares as well as the issuance of special rights referred to in Chapter 10 Section 1 of the Finnish Companies Act to provide more alternatives for financing the development of the Company's new business opportunities.

Under the authorisation, the number of new shares that may be issued based on decision(s) of the Board of Directors would not exceed 418,980,716 shares, which corresponds to approximately 10 percent of all shares in the Company, and the number of the Company's own shares that may be transferred would not exceed 209,490,358 shares, which corresponds to approximately 5 percent of all shares in the Company.

Furthermore, the Board of Directors would be authorised to issue special rights referred to in Chapter 10 Section 1 of the Finnish Companies Act entitling their holder to receive new shares or the Company's own shares for consideration in such a manner that the subscription price of the shares is to be set off against a receivable of the subscriber (convertible bond). The number of shares which may be issued or transferred based on the special rights shall not exceed 418,980,716 shares, which corresponds to approximately 10 percent of all shares in the Company. This aggregate number of shares is included in the aggregate numbers of shares that may be issued and transferred mentioned in the previous paragraph.

The new shares could be issued and the Company's own shares could be transferred for consideration, including a set-off against a receivable from the Company, or without consideration. The new shares and the special rights referred to in Chapter 10 Section 1 of the Finnish Companies Act could be issued and the Company's own shares transferred to the shareholders in proportion to their current shareholdings in the Company or in deviation from the shareholders' pre-emptive rights by way of a directed issue if there is a weighty financial reason for the Company to do so. The deviation from the shareholders' pre-emptive rights could be carried out, for example, in order to develop the Company's capital structure or in order to finance or carry out acquisitions, investments or other business transactions. A directed share issue would be executed without consideration only if there is a particularly weighty financial reason for the Company to do so, taking the interests of all its shareholders into account. Should the total number of the shares in the Company later decrease as a result of a reverse share split, the maximum number of shares to be issued based on the authorisation would decrease pro rata.

The Board of Directors would have the right to decide on all other matters related to the issuance of sharesand the special rights referred to in Chapter 10 Section 1 of the Finnish Companies Act. The authorisation is proposed to be valid until 31 December 2018 and it would not cancel the share issue authorisation given by the extraordinary general meeting on 2 February 2017.

8. Reduction of the reserve for invested unrestricted equity to cover accumulated deficit

The Board of Directors proposes that the extraordinary general meeting would resolve to reduce the reserve for invested unrestricted equity pursuant to the balance sheet of the Company per 30 June 2017, EUR 799,729,611, in its entirety. The reserve for invested unrestricted equity would be EUR 0 after the reduction and the reserve for invested unrestricted equity would dissolve. The reduced amount would be used to cover the accumulated deficit pursuant to the balance sheet per 30 June 2017, EUR 816,835,314. Following the loss coverage, the amount of the accumulated deficit on the balance sheet of the Company would be EUR 17,105,703.

9. Reduction of the share premium reserve to cover accumulated deficit

The Board of Directors proposes that the extraordinary general meeting would resolve to reduce the share premium reserve pursuant to the balance sheet of the Company per 30 June 2017, EUR 8,085,842, in its entirety. The share premium reserve would be EUR 0 after the reduction and the share premium reserve would dissolve. The reduced amount would be used to cover the accumulated deficit on the balance sheet to the extent the deficit is not covered by the unrestricted equity. After the reduction of the reserve for invested unrestricted equity pursuant to the balance sheet of the Company mentioned in the agenda item 8, the amount of accumulated deficit would be EUR 17,105,703. After the reduction of the share premium reserve mentioned in this agenda item, the amount of accumulated deficit on the balance sheet of the Company would be EUR 9,019,861.

10. Applying for the public notice to the creditors

The Board of Directors proposes that the extraordinary general meeting would resolve to allow the Board of Directors to decide separately if the Company will apply for a public notice to the creditors from the Finnish Patent and Registration Office (Finnish Trade Register) due to the decision concerning the reduction of the share premium reserve. The public notice shall be applied within one (1) month from the decision of the general meeting.
