  a.  The members shall take action by the affirmative vote of the members of the greater of any of the following:
  (1)  A majority of the voting power of the membership interests present and entitled to vote on that item of business.
  (2)  A majority of the voting power that would constitute a quorum for the transaction of business at the meeting, except where this chapter, the articles or bylaws, or a member control agreement requires a larger proportion.
  b.  If the articles, bylaws, or a member control agreement require a larger proportion than is required by this chapter for a particular action, the articles, bylaws, or the member control agreement shall have control over the provisions of this chapter.
  2.  Class or series of membership interests.  In any case where a class or series of membership interests is entitled by this chapter, the articles, bylaws, a member control agreement, or the terms of the membership interests to vote as a class or series, the matter being voted upon must also receive the affirmative vote of the owners of the same proportion of the membership interests present of that class or series; or of the total outstanding membership interests of that class or series, as the proportion required under subsection 1, unless the articles, bylaws, or the member control agreement requires a larger proportion. Unless otherwise stated in the articles, bylaws, or a member control agreement, in the case of voting as a class or series, the minimum percentage of the total voting power of membership interests of the class or series that must be present is equal to the minimum percentage of all membership interests entitled to vote required to be present under section 501A.806.
