“At all meetings of shareholders, a shareholder may vote in person or by proxy, executed in writing by the shareholder or transmitted by the shareholder as permitted by law, including, without limitation, by telephone, electronically, via telegram, internet, interactive voice response system, or other means of electronic transmission executed or authorized by such shareholder or by the shareholder’s duly authorized attorney-in-fact; but, no proxy shall be valid after eleven (11) months from its date, unless the proxy provides for a longer period.”
