4.  REPRESENTATIVES

The Authority and the Contractor may appoint their representatives on the Liaison Committee and remove those representatives and appoint replacements, by written notice delivered to the other at any time.  A representative on the Liaison Committee may appoint and remove an alternate (who may be another representative of that party) in the same manner.  If a representative is unavailable (and the other Parties' representative may rely on the alternate's statement that the representative is unavailable) his alternate shall have the same rights and powers as the representative.
