          Exelon Corporation Announces Acquisition of Illinois Power's
                             Assets from Dynegy Inc.

CHICAGO (November 3, 2003) - Exelon Corporation, the parent company of Illinois
utility ComEd, today announced that it has entered into an agreement with Dynegy
Inc., to acquire substantially all of the operating assets of Illinois utility
Illinois Power. The purchase price of $2.225 billion includes the assumption of
approximately $1.8 billion of Illinois Power's debt at closing, a $150 million
promissory note from Exelon and approximately $275 million of cash, subject to
adjustment for working capital. The acquisition is expected to help protect
jobs, guarantee long-term, stable electric rates for millions of customers and
ensure reliable service for ComEd and Illinois Power customers. Exelon officials
said the acquisition is consistent with the company's strategy to provide
sustainable and predictable earnings and cash flow growth.

Each company's board of directors approved the acquisition. It also requires the
approval of the Illinois Commerce Commission (ICC), the Federal Energy
Regulatory Commission, the Securities and Exchange Commission, and other federal
agencies. Depending on the timing of these regulatory approvals the transaction
is expected to close in the fourth quarter of 2004.

"We believe that this transaction will be good for Exelon's customers, employees
and investors and Illinois Power's customers and employees," said Exelon
Chairman and CEO John W. Rowe. "This agreement has the potential to establish
long-term, stable and reasonable rates for millions of ComEd and Illinois Power
customers, and provide stability for the working men and women of Illinois
Power. However, to make this work, we will need additional clarity and certainty
after the state-mandated transition period ends on December 31, 2006."

Rowe said that the passage of legislation that will be introduced in the
Illinois General Assembly during its November session is necessary to facilitate
the acquisition. Exelon, ComEd, Dynegy and Illinois Power, as well as a broad
and diverse base of labor, business and community groups, are supporting the
legislation, which would authorize the ICC to complete a review of the
transaction within nine months.

The legislation would give the ICC the authority to set rates for four years
after the transition period ends in 2006, which would pave the way for stable
rates for smaller ComEd and Illinois Power customers through the end of 2010.
Even with a modest increase in rates in 2007, ComEd and Illinois Power's smaller
customers would still be paying rates well below those of the early 1990s.

In addition, with set rates customers will be protected against volatile
electric bills. If there are spikes in gas and wholesale electric prices, Exelon
bears the risk since customers will have the benefit of a stable rate. If gas
and wholesale electric prices go down, customers have the option to switch to
another electric company and take advantage of lower prices that competitors
offer.

"We believe this transaction will help the Illinois Power business regain
financial strength and stability, but we need to move forward sooner rather than
later," Rowe said. "Exelon, ComEd and Illinois Power want to provide electricity
to smaller customers at prices that do not vary with gas prices and nuclear
performance, but to do that, ComEd and Illinois Power must have a better idea of
what the future holds. In the utility world, 2007 is right around the corner. We
need to start planning now."

"Competition is working for large consumers, for utilities and for our electric
supply competitors," Rowe said. "This acquisition will help support the
competitive marketplace. By bringing pro-competitive rules to more of the
state's electric market, it will be easier for competitors to navigate across a
larger area and customer base."

Exelon has demonstrated that it is willing to make the investments necessary to
maintain and improve electric reliability, including investing more than $2
billion over the past five years to improve and maintain ComEd's electric
system. Through any transaction, Exelon's commitment to reliable electric
service would be reflected in investments in Illinois Power's infrastructure.

Following the approvals required for Exelon's acquisition, the Illinois Power
business will retain its name and will be operated as a separate unit under
Exelon's energy delivery business. In addition, Illinois Power's 1,800 employees
will become part of Exelon. Illinois Power will also join the PJM
Interconnection as a part of the acquisition. ComEd expects to join PJM next
spring. ComEd will continue to serve Northern Illinois, and Illinois Power will
continue to serve Central and Southern Illinois.

(10 AM CT) on November 3. The call-in number in the US is 877-715-5317 and the
international call-in number is 973-582-2720. No password is required. Media
