(805 ILCS 5/11.20) (from Ch. 32, par. 11.20)
    Sec. 11.20. Approval by shareholders.
    (a) A vote of the shareholders entitled to vote on the proposed plan of merger, consolidation or exchange shall be taken. The plan of merger, consolidation or exchange shall be approved upon receiving by each corporation the affirmative votes of at least two-thirds of the votes of the shares entitled to vote on the plan unless any class or series of shares of any of such corporations is entitled to vote as a class on the plan in which event, as to such corporation, the plan of merger, consolidation or exchange shall be approved upon receiving the affirmative votes of at least two-thirds of the votes of the shares of each such class or series of shares entitled to vote as a class on the plan and of the votes of the total shares entitled to vote on the plan. Any class of shares of any such corporation shall be entitled to vote as a class if the articles of incorporation so provide or if the plan of merger, consolidation or exchange, as the case may be, contains any provision which, if contained in a proposed amendment to articles of incorporation, would entitle such class of shares to vote as a class.
    (b) The articles of incorporation of any corporation may supersede the two-thirds vote requirement of this Section as to that corporation by specifying any smaller or larger vote requirement not less than a majority of the votes of the shares entitled to vote on the issue and not less than a majority of the votes of the shares of each class or series of shares entitled to vote as a class on the issue.
    (c) No vote by the shareholders of a corporation that is a surviving party to a plan of merger or that is the acquiring corporation in a plan of exchange shall be required, unless its articles of incorporation provide to the contrary, if:
        (1) the plan of merger or exchange does not amend in
    
any respect the articles of incorporation of such corporation;
        (2) each share of such corporation outstanding
    
immediately prior to the effective date of the merger or exchange has the identical designations, preferences, qualifications, limitations, restrictions and special or relative rights immediately after the effective date thereof; and
        (3) either no common shares of the surviving or
    
acquiring corporation and no shares, securities or obligations convertible into such shares are to be issued or delivered under the plan of merger or exchange, or the authorized unissued common shares of the surviving or acquiring corporation to be issued or delivered under the plan of merger or plan of exchange, plus those initially issuable upon conversion of any other shares, securities or obligations to be issued or delivered under such plan, do not exceed 20 per cent of the common shares of such corporation outstanding immediately prior to the effective date of the merger or exchange.
