                 Exelon to Match FPL's $276.5-Million Offer for
                      AmerGen Purchase from British Energy


CHICAGO (October 3, 2003) -- Exelon Corporation announced today that it will buy
British Energy's 50-percent interest in AmerGen Energy Co. LLC for $276.5
million, giving Exelon sole ownership of AmerGen and its three nuclear plants.

The amount matches the offer by FPL Energy, which announced Sept. 11 that it
intended to buy British Energy's share of AmerGen. Under the AmerGen agreement
between Exelon and British Energy, either can exercise a "right of first
refusal" by matching any bona fide third-party offer agreed to by the other
partner.

AmerGen owns the Clinton Power Station in central Illinois, Three Mile Island
Unit 1 near Harrisburg, Pa., and the Oyster Creek Generating Station on the New
Jersey shore. The three stations represent about 2,500 megawatts of generating
capacity.

"We're delighted to bring AmerGen and Clinton, Oyster Creek and TMI-1 completely
inside the Exelon family," said Exelon Chairman and CEO John Rowe. "We were
satisfied in our relationship with British Energy, but if we had to make a
change, this was the best possible outcome."

Exelon's decision to purchase British Energy's interest ends a yearlong effort
that began in September 2002 with an announcement that both companies intended
to explore the possible sale of AmerGen. Exelon withdrew from the exploratory
sale in March 2003 because bids received for AmerGen were insufficient, but
British Energy continued to look for a buyer for its one-half interest.

Exelon Nuclear President and CNO Jack Skolds, who is also Chairman of AmerGen,
said the three single-unit sites are already operationally integrated with
Exelon Nuclear and will continue their record of safe and reliable operation.
AmerGen is the NRC licensee for the three units.



"We've made extensive improvements at all three plants since their purchase by
AmerGen," Skolds said. "Our commitment is to ensure the safety and efficiency of
these plants, and we will continue to improve our overall performance."


Exelon currently owns a half-share in AmerGen. The purchase will increase
Exelon's "owned" nuclear generation capacity by about 1,250 megawatts, to more
than 16,000 megawatts. Exelon's overall "managed" nuclear generation will remain
at 17,800 megawatts because Exelon already manages the three AmerGen plants and
includes them as a part of the Exelon fleet.

Exelon believes the AmerGen sites have significant long-term value.
License-extension studies are under way at Three Mile Island Unit 1 and Oyster
Creek. On Sept. 25, Exelon submitted an Early Site Permit application to the
U.S. Nuclear Regulatory Commission identifying the Clinton property as a
candidate for future nuclear construction should the company ever decide to
build a new nuclear plant.

The AmerGen sale is expected to be completed in the first half of 2004.

When the transaction is complete, Exelon will fully own eight of the 10 nuclear
stations it operates. The company will continue to share ownership of two
stations - Peach Bottom Atomic Power Station in Pennsylvania (with PSE&G owning
50 percent) and Quad Cities Generating Station in Illinois (with Mid-American
Energy owning 25 percent). Exelon also owns 50 percent the Salem Nuclear Power
Station in New Jersey, which is operated by PSE&G.
