Absorbed Company C held 20,080,000 shares corresponding to 100% of the shares in the share capital of Absorbed Company D.

Given that the Absorbing Company owned directly or indirectly the entirety (100%) of the shares of Absorbed Company B, Absorbed Company C and Absorbed Company D, the provisions of article 78 et seq. of Codified Law 2190/1920 were also applied in conjunction with the above legislation, specifically in respect of the said Absorbed Companies, for which no new shares will be issued.

It is pointed out that the exchange ratio for the shareholders of the merging companies is as follows:

• The shareholders of the absorbed company METKA shall receive, for each (1) share of a nominal value of €0.32 which they hold in the absorbed company, one (1) common registered voting share of the Absorbing Company, of a nominal value of €0.97.

• The shareholders of the Absorbing Company shall continue to own one (1) common registered voting share for each (1) share the owned before the Merger, of a nominal value of €0.97.

It is noted that the shares in the share capital of the Absorbed Company B and Absorbed Company C shall not be exchanged for shares in the share capital of the Absorbing Company, given that these shares are wholly owned by the Absorbing Company. The same applies to the shares in the share capital of the Absorbed Company D, as these shares are wholly owned by the Absorbing Company C and, consequently, they shall be transferred to the Absorbing Company upon completion of the merger.
