Bylaws shall be necessary and sufficient to constitute a quorum for the
transaction of business except as otherwise provided by statute, the Articles of
Incorporation, or these Bylaws. The act of a majority of the directors present
at a meeting at which a quorum is present shall be the act of the Board of
Directors unless the act of a greater number is required by statute, the
Articles of Incorporation, or these Bylaws, in which case the act of the greater
number shall be requisite to constitute the act of the Board of Directors. If a
quorum shall not be present at any meeting of directors, the directors present
thereat may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present. At any adjourned
meeting any business may be transacted that might have been transacted at the

compensation therefor.
