Ladies and Gentlemen:

          We are writing to you with respect to Central Illinois Light
Company ("CILCO") and its parent, CILCORP Inc., and the pending merger
transaction involving CILCORP Inc. and The AES Corporation.

          We have been advised that The AES Corporation, through its
subsidiaries (other than CILCORP Inc. or subsidiaries of CILCORP Inc.),
affiliates, or through other entities, currently holds, and intends to
continue to hold and acquire, ownership interest in electric and natural
gas facilities in one or more foreign countries. We submit this letter
pursuant to the requirements of Section 33(a)(2) of the Public Utility
Holding Company Act of 1935, as amended (the "Act").

          A 1997 Illinois law implemented changes to historical utility
regulation. The law required all regulated electric utilities to reduce
their rates to residential consumers in 1998 and, subject to certain
specified exceptions, froze such electric rates until 2005. While neither
the utilities nor the Illinois Commerce Commission ("Commission") can
change bundled electric rates until 2005, the Commission retains
jurisdiction to set rates for unbundled delivery service. In addition,
electric utilities are subject to other statutory provisions that require a
sharing of revenues with consumers if the utility earns more than certain
specified thresholds. However, the restructuring legislation gave electric
utilities great flexibility in writing down assets and accelerating
depreciation, so utilities may be able to avoid triggering the over-earning
threshold. Also, the legislation removed Commission authority over the
sale, lease or other transfer of assets to affiliated or unaffiliated
entities until January 1, 2005. Also, the Commission has jurisdiction over
electric and gas delivery system reliability. However, the Commission
cannot order a utility to construct additional generation. Finally, while
the Commission's authority to approve or disapprove some merger and
reorganization transactions has been suspended until 2005, regulated
utilities are required to provide the Commission with a 30-day advanced
notice of any proposed transaction, with supporting documentation, and to
file certain reports thereafter.
