Methods of consulting Shareholders. Collective decisions of the Shareholders shall be called as often as the interests of the Company so require at the initiative of either the President, or the General Manager, or one or more Shareholders representing alone or together at least thirty (30) percent of the voting rights or, in the event of the dissolution of the Company, by the liquidator, or by an auditor. However, an auditor may only act after having unsuccessfully requested the President, by registered letter with acknowledgement of receipt, to organise a consultation of the Shareholders. Each Shareholder shall have the right to participate in collective decisions and, subject to the possible existence of Shares with multiple voting rights, shall have a number of votes equal to the number of Shares he owns. A Shareholder may be represented in collective decisions by any person of his choice, whether a Shareholder or not, who must justify his mandate by communicating it to the President. Shareholders may be consulted at the meeting, by correspondence, fax, or by any means of videoconferencing or telecommunications, or by any other means allowing the identification and effective participation of the participants, or by any notarial or private deed signed by the Shareholders or their representatives.
