If mailed, such notice shall be deemed to be delivered when deposited in the United States mail, addressed to the shareholder at his or her address as it appears on the stock transfer books of the corporation, with postage thereon prepaid.

        Section 5. Closing of Transfer Books or Fixing of Record Date. For the purpose of determining shareholders entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof or shareholders entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other proper purpose, the Board of Directors of the corporation may provide that the stock transfer books shall be closed for a stated period, but not to exceed, in any case, sixty (60) days.  If the stock transfer books shall be closed for the purpose of determining shareholders entitled to notice of or to vote at a meeting of the shareholders, such books shall be closed for a period of at least ten (10) days immediately preceding such meeting and not to exceed sixty (60) days preceding such meeting.  In lieu of closing the stock transfer books, the Board of Directors may fix in advance a date as the record date for any such determination of shareholders, such date in any case to be not more than sixty (60) days and, in case of a meeting of shareholders, not less than ten (10) days prior to the date on which the particular action requiring such determination of shareholders is to be taken.  If the stock transfer books are not closed and no record date is fixed for the determination of shareholders entitled to receive payment of a dividend, the date on which the resolution of the Board of Directors declaring such dividend is adopted, as the case may be, shall be the record date for such determination of shareholders.  When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this section, such determination shall apply to any adjournment thereof.

        Section 8.  Voting of Shares.  Subject to the provisions of Section 10 of this Article II, each outstanding share shall be entitled to one vote, and each fractional share shall be entitled to a corresponding fractional vote, on each matter submitted to a vote at a meeting of shareholders. Neither treasury shares nor shares of its own stock held by the corporation in a fiduciary capacity nor shares held by another corporation if a majority of the shares entitled to vote for the election of director of such other corporation is held by the corporation shall be voted at any meeting or counted in determining the total number of outstanding shares at any given time.

        Shares held by an administrator, executor, guardian or conservator may be voted by him or her, either in person or by proxy, without a transfer of such shares into his or her name.  Shares standing in the name of the trustee may be voted by him or her, either in person or by proxy, but no trustee shall be entitled to vote shares held by him or her without a transfer of such shares into his or her name.

        Shares standing in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without the transfer thereof into his or her name if authority so to do be contained in an appropriate order of the court by which such receiver was appointed.

        A shareholder whose shares are pledged shall be entitled to vote such shares until the shares have been transferred into the name of the pledgee, and thereafter the pledgee shall be entitled to vote the shares so transferred.

        Shares of its own stock belonging to the corporation or held by it in a fiduciary capacity shall not be voted, directly or indirectly, at any meeting, and shall not be counted in determining the total number of outstanding shares at any given time.

        Section 10.  Cumulative Voting.  At each election for directors every shareholder entitled to vote at such election shall have the right to vote, in person or by proxy, the number of shares and fractional shares owned by him or her for as many persons as there are directors to be elected and for whose election he or she has a right to vote, or to cumulate his or her votes by giving a candidate as many votes as the number of such directors multiplied by the number of his or her shares including fractional shares shall equal, or by distributing such votes and fractional votes on the same principal among any number of candidates.
