An alternate for a member of the committee shall act in the place and stead of such member (a) during such member's absence, and (b) in the event of such member's removal, resignation, disqualification or death, until a successor for such member's unexpired term has been selected and has qualified.

The committee or the chariman of the committee may request one or more alternates to attend any or all meetings notwithstanding the expected or actual attendance of the respective member or members.
