  Dynegy, Exelon To Terminate Agreement Regarding Sale of Illinois Power Assets

HOUSTON and CHICAGO (November 22, 2003) - Dynegy Inc. (NYSE: DYN), parent
company of Illinois Power, and Exelon Corporation (NYSE: EXC), parent company of
ComEd, today acknowledged their disappointment that the Illinois General
Assembly did not act in the fall legislative session to approve the legislation
necessary to facilitate Exelon's proposed acquisition of Illinois Power, but
both companies expressed their appreciation for the support they received from
many legislators and labor and community organizations.

In the absence of the legislation, Dynegy and Exelon announced that they will
terminate the existing agreement through which Exelon would have acquired
substantially all of the assets and liabilities of Illinois Power. Dynegy and
Exelon said that the current legislative and regulatory environment made it
impossible to complete the transaction in accordance with the original
agreement.

"Exelon's acquisition of Illinois Power would have been good for the state of
Illinois. While we are disappointed that the legislation did not pass, we must
now focus on the future with Illinois Power as a part of our organization," said
Dynegy Inc. President and CEO Bruce A. Williamson. "Our first priority will be
to improve Illinois Power's financial condition by creating a sustainable cost
structure for this business. We will work closely with the Illinois Commerce
Commission and the union throughout this process.

"We will ensure safe, reliable and affordable service for our electricity and
natural gas customers in Illinois while we restructure Illinois Power to make it
a sustainable business and implement changes as soon as possible to cut costs,"
Williamson added.



According to Exelon Chairman and CEO John W. Rowe, "I really believe that this
transaction would have benefited the state of Illinois, our customers, our
investors, and certainly the employees of Illinois Power. Given the outcome of
the legislation, the terms of the current acquisition agreement cannot be met.
Exelon recognizes that it is not in the interest of the customers, employees or
investors of either company to pursue a deal that no longer has a realistic
chance of successful completion. We recognize Dynegy's need to pursue other
business plans for Illinois Power."

The legislation that Exelon and ComEd had originally proposed, which was
contained in House Bill 2200, would have allowed many of the regulatory issues
to be addressed in a single Illinois Commerce Commission (ICC) proceeding. The
legislation also would have directed the ICC to conduct the acquisition review
in an expedited nine-month proceeding, and would have allowed for full ICC and
Federal Energy Regulatory Commission review of power purchase agreements related
to the acquisition.
