Should the conditions of article 27 of the Law 3461/2006 be fulfilled and having exercised the “Right of Squeeze - out” right, the Offeror will pursue the delisting of the shares of the Company from the ATHEX  according to article 17, paragraph 5 of the Law 3371/2005.

In case the article 27 conditions of the Law 3461/2006 are not met, therefore the Offeror not being in a position to exercise the “Right of Squeeze - out”, the Offeror will pursue the delisting of the Company shares from the ATHEX by the means of a relevant decision by the General Assembly of Company shareholders which requires a 95% favorable vote of the total number of voting rights of the Company according to article 17, paragraph 5 of the Law 3371/2005.
