CORP § 112

If the articles provide for more or less than one vote for any share on any matter, the references in Sections 152, 153 and 602 to a majority or other proportion of shares means, as to such matter, a majority or other proportion of the votes entitled to be cast. Whenever in this division shares are disqualified from voting on any matter, they shall not be considered outstanding for the determination of a quorum at any meeting to act upon, or the required vote to approve action upon, that matter under any other provision of this division or the articles or bylaws.
