announced  that  Paul J.  McAuliffe,  49,  has  elected  to step  down as  chief

At the same time, Mr. McAuliffe will step down as the chief financial officer of

McAuliffe  plans to return  with his  family to his  native  New  Jersey.  Since
October 1999, Mr. McAuliffe has served as the chief financial  officer of Aimco.
Aimco will begin an orderly  transition with Thomas M. Herzog, 42, currently the

Mr.  McAuliffe as chief  financial  officer.  Since January 2004, Mr. Herzog has
served as senior vice  president and chief  accounting  officer of Aimco and the
Managing  General  Partner.  Effective  July 1, 2005,  Mr.  Herzog  will  become
executive vice president and chief accounting  officer of Aimco and the Managing
General  Partner  and will  assume the chief  financial  officer  title when Mr.
McAuliffe  assumes  his new role in early 2006.  Prior to joining  Aimco and the
Managing  General  Partner,  Mr. Herzog was at GE Real Estate,  serving as chief
accounting  officer and global controller from April 2002 to January 2004 and as
chief technical  advisor from March 2000 to April 2002. Prior to joining GE Real
Estate, Mr. Herzog was at Deloitte & Touche LLP from 1990 to 2000. The successor
to Mr.  Herzog  in the  role of  chief  accounting  officer  has  not  yet  been
determined.
