Section 1.05. Inspectors at Shareholders’ Meetings. The Board of Directors, in advance of any shareholders’ meeting, may appoint one or more inspectors to act at the meeting or any adjournment thereof.

In case any person appointed fails to appear or act, the vacancy may be filled by appointment made by the Board of Directors in advance of the meeting or at the meeting by the person presiding thereat. Each inspector, before entering upon the discharge of his duties, shall take and sign an oath faithfully to execute the duties of inspector at such meeting with strict impartiality and according to the best of his ability.

The inspectors shall determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots or consents, determine the result and do such acts as are proper to conduct the election or vote with fairness to all shareholders. On request of the person presiding at the meeting or any shareholder entitled to vote thereat, the inspectors shall make a report in writing of any challenge, question or matter determined by them and execute a certificate of any fact found by them. Any report or certificate made by them shall be prima facie evidence of the facts stated and of the vote as certified by them.
