Subject: 3. If at any time the share capital is divided into different classes of shares, the rights attached to any class (unless otherwise provided by the terms of issue of the shares of that class) may, whether or not the company is being wound up, be varied with the consent in writing of holders of three-fourths of the issued shares of that class, or with the sanction of an extraordinary resolution passed at a separate general meeting of the holders of the shares of the class. To every such separate general meeting the provisions of these articles relating to general meetings shall apply, but so that the necessary quorum shall be two persons at least holding or representing by proxy one-third of the issued shares of the class and that any holder of shares of the class present in person or by proxy may demand a poll. The provision of Article 88 relating to passing of resolution in writing by the members shall apply mutatis mutandis.
