ANNOUNCEMENT ACCORDING TO LAW 3556/2007

EYDAP SA announces, pursuant to Law 3556/2007 and to the relevant notification dated 27.1.2012, the transfer from the Hellenic State of 29,074,500 shares of EYDAP S.A., and the equal number of voting rights, i.e. 27.30% of share capital of the Company, to the "Hellenic Republic Asset Development Fund''. The transfer was the result of an OTC market transaction, pursuant to paragraphs 4 and 5 of Article 2 of the Law 3986/2011 (GG 152/A) and Decision no. 195/2011 (GG 2501/B) of the Ministerial Committee for Asset Restructuring and Privatization.

It is worth noting that now the percentage of the Hellenic government in the share capital of EYDAP S.A. is 34.03%.

Since the Hellenic government controls 100% of the "Hellenic Republic Asset Development Fund'', it indirectly controls the above voting rights.
