6. Sale of mining-related assets to Terrafame

The Board of Directors proposes that the extraordinary general meeting would approve the sale by Talvivaara of its assets related to the Sotkamo mining operations (the "Mining Assets") to Terrafame Ltd ("Terrafame").

On 30 June 2016, Talvivaara and Terrafame signed agreements pursuant to which the parties agreed on the sale of the Mining Assets to Terrafame (the "Agreements"). The Mining Assets include, among others, the lime plant needed for the Sotkamo operations, laboratory, as well as rights to the geological, laboratory and production related data associated with the Sotkamo mine.

The purchase price for the assets sold consists of a cash component of EUR 1.4 million payable by Terrafame to the Company and a full and final settlement of the guarantee liability of the Company under the Loan and Streaming Holiday Agreement, with the principal amount of approximately EUR 14 million (including interest up until 30 June 2016). In connection therewith, the Company and Terrafame also agreed on a full and final settlement of the guarantee liability of the Company under the Zinc in Concentrate Purchase Agreement, amounting to approximately EUR 203.4 million.

Certain shareholders of the Company, comprising of Solidium Ltd and Mr. Pekka Perä, CEO of Talvivaara, who together represent approximately 20 per cent of the ordinary shares currently issued and outstanding (excluding 192,883,000 shares held in treasury by the Company not carrying any voting rights), have preliminary agreed to vote in favour of the transaction at the extraordinary general meeting.

Should the extraordinary general meeting not approve the sale of the Mining Assets, the Agreements would be cancelled and the transactions revoked and, consequently, the parties would resume the positions existing immediately prior to the signing of the Agreements which could lead to the bankruptcy of the Company.
