The following items are financial guarantees and commitments of system
companies:
   At December 31, 2002, HPI had extended commitments to provide $1,567,000 in
   financing to developers which were secured by affordable housing
   properties.  HPI anticipates other lenders will ultimately finance these
   properties.  The highest amount outstanding during 2002 was $2,479,000 and
   no consideration was received by HPI other than the purpose of the
   commitments described above.
