    Each member of  the  board  of  the  Planetarium  Authority  shall  be

    The board of  the  Planetarium  Authority  may  appoint  an  executive
  director.  The  members  of  the board and the executive director of the
  Planetarium Authority shall serve pro bono and shall be entitled  to  no
  compensation  for  their services or reimbursement for expenses incurred
  or to be incurred in connection with the planetarium hereby  authorized.
  A  majority  of  the  members  of the board of the Planetarium Authority
  shall constitute a quorum at any meeting of the board, and a majority of
  the members present at a meeting of the board at which there is a quorum
  may exercise the powers of the authority. The board of  the  Planetarium
  Authority may delegate to one or more of its members or to its officers,
  any  such  powers  and  duties  as  it  may deem proper. The Planetarium
  Authority shall continue the lease with the American Museum  of  Natural
  History   for   the  exclusive  occupancy,  operation  and  use  of  the
  planetarium by the American Museum of Natural History for the purpose of
  carrying out the purposes set forth above and related purposes, all upon
  the obligation of the American Museum of Natural  History  to  keep  the
  planetarium  in  reasonable  repair,  and  to  maintain  and operate the
  planetarium, which lease may be of indefinite duration  terminable  only
  upon  surrender  of  the lease by the direction and authorization of the
  board of trustees of the American Museum of Natural History.
    The existence  of  the  Planetarium  Authority  shall  continue  until
  dissolved  by its board, provided that all its liabilities have been met
  and its bonds have been paid in full or such liabilities or  bonds  have
  been  discharged  and  provided further that the Planetarium Authority's
  lease to  the  American  Museum  of  Natural  History  shall  have  been
  surrendered  by  the American Museum of Natural History. Notwithstanding
  the foregoing, the Planetarium Authority shall  be  dissolved  when  the
  American   Museum  of  Natural  History  surrenders  its  lease  of  the
  planetarium  to  the  Planetarium  Authority,  provided  that  all   its
  liabilities  have  been met and its bonds have been paid in full or such
  liabilities or bonds have been discharged or  assumed  by  the  American
  Museum  of  Natural  History. Upon its ceasing to exist, all of its real
  property shall pass to the city of New York  and  all  of  its  personal
  property  shall  pass  to The American Museum of Natural History for its
  corporate purposes. Thereupon, such real property  shall  be  maintained
  and  operated  in  the  same  manner and subject to the same provisions,
  restrictions and authorities and by the same corporation  as  the  other

  property  of  the city of New York which is now occupied by The American
  Museum of Natural History.
