IPALCO's electric revenues are allocated between electric generation and
electric transmission and distribution activities according to utility rate
base. CILCORP's electric revenues are allocated between electric generation and
electric transmission and distribution activities according to utility rate
base. AES generation revenues are derived from the total generation revenues
earned by AES subsidiaries times the percentage ownership interest of AES in
those subsidiaries.

There has been no change in the amount of generation capacity owned by CILCORP
or IPALCO and a 172 MW increase in the amount of generation capacity owned by
AES (excluding CILCORP and IPALCO) from 34,770 to 34,942 MW since March 31,
2001. There has been a 6% increase in the total revenues earned from the
capacity owned by AES, IPALCO and CILCORP in the twelve-month period ended June
30, 2001 compared with the twelve-month period ended March 31, 2001. The
percentage of total revenues derived from the generation capacity owned by
CILCORP has stayed the same at 4%. The percentage of total revenues derived from
the generation capacity owned by IPALCO stayed the same at 5%.

The physical location of the MW capacity added by AES since March 31, 2001 is in
the United States, the Czech Republic and Germany.
