(a) A shareholder may appoint a proxy to vote or otherwise act for him or her by delivering a valid appointment form to the person so appointed or to a proxy solicitation firm, proxy support service organization, or like agent duly authorized by the person or persons to receive the transmission. Without limiting the manner in which a shareholder may appoint such a proxy pursuant to this Section 7.50, the following shall constitute valid means by which a shareholder may make such an appointment: (1) A shareholder may sign a proxy appointment form. The shareholder's signature may be affixed by any reasonable means, including, but not limited to, by facsimile signature.(2) A shareholder may transmit or authorize the transmission of a telegram, cablegram, or other means of electronic transmission; provided that any such transmission must either set forth or be submitted with information from which it can be determined that the telegram, cablegram, or other electronic transmission was authorized by the shareholder. If it is determined that the telegram, cablegram, or other electronic transmission is valid, the inspectors or, if there are no inspectors, such other persons making that determination shall specify the information upon which they relied. Any copy, facsimile telecommunication, or other reliable reproduction of the writing or transmission may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that the copy, facsimile telecommunication, or other reproduction shall be a complete reproduction of the entire original writing or transmission.
