the pleasure of the Board of Directors and shall keep minutes of its meetings

more directors as alternate members of any committee, who may replace any absent
or disqualified member or members at any meeting of the committee. In addition,
in the absence or disqualification of a member of a committee, if no alternate

present at any meeting and not disqualified from voting, whether or not they
constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of the absent or disqualified
