              Exelon Corporation Explores Possibility of Acquiring
                        Illinois Power from Dynegy Inc.

Chicago (September 26, 2003) -- Exelon Corporation (Exelon) today announced that
it is engaged in exclusive discussions with Dynegy Inc. (Dynegy), which may lead
to Exelon purchasing Illinois Power Company (Illinois Power) from Dynegy.
Illinois Power is an electric and gas distribution and transmission utility
serving customers in north central, central and south central Illinois.
Negotiations have only commenced and no assurance can be given that they will
lead to an agreement or that any such agreement could be consummated.

While Exelon believes it is possible to structure a transaction that will
achieve important public policy objectives such as greater reliability and price
stability, any ultimate transaction will be contingent upon review by the
Illinois Commerce Commission, the Federal Energy Regulatory Commission, the
Securities and Exchange Commission and other governmental entities to assure
that these objectives are met. It is expected that if this acquisition is
consummated, it will benefit consumers, competition and the state's economy.

Exelon is exploring this transaction because it believes the combination of
Illinois Power with Exelon's present subsidiary, Commonwealth Edison Company
(ComEd), would provide a unique opportunity to improve service to customers and
address the issues involving the supply and price of electricity throughout much
of the state through the end of the decade and beyond. We would expect that an
approved transaction would lead to contracts for guaranteed supply at
predictable prices for Illinois consumers, particularly residential and small
commercial.








Safe, reliable delivery of energy to our customers remains Exelon's first
priority. Exelon is committed to constantly monitoring opportunities that will
not only enhance shareholder value, but also improve reliability.

Exelon does not anticipate making any further announcement until a definitive
agreement is reached or the discussions are terminated.
