Special meetings are attended by the holders of shares of a given class.
A decision by a general meeting to amend the rights relating to a class of shares is only definitive after approval by the special meeting of shareholders of that class.
Special meetings are valid only if the shareholders present or represented own at least, on first call, one third and, on second call, one fifth of the shares with voting rights and whose rights it is proposed to amend. Failing this, the second meeting may be adjourned to a date no more than two months after the date on which it was convened. The Articles of Association may provide for higher quorums.
They decide under the conditions provided for in the third paragraph of Article L. 225-96.
