(1)  Represents total budgeted land and development costs.
(2)  Represents the quarter that the first completed units were made available
     for leasing (or are expected to be made available).  Archstone begins
     leasing completed units prior to completion of the entire community.
(3)  The percentage leased is based on leased units divided by total number of
     units in the community (completed and under construction) as of September
     30, 1999.  An "n/a" indicates the communities where lease-up has not yet
     commenced.
