A shareholder’s proxy holder shall enjoy the same rights to speak
and ask questions at one or both Meetings as those afforded to the respective shareholder. Pursuant to the Shareholders’ Rights
Law, irrespective of the number of Shares held, a shareholder may appoint only one proxy holder to represent such shareholder at one or
