Note to Exelon's Financial Community:


             Exelon Generation Company, LLC Exercises Options under
              Purchase Power Agreement with Midwest Generation, LLC


On July 1, 2002, Exelon Generation notified Midwest Generation, LLC (Midwest) of
its exercise of Exelon Generation's call option under the existing Coal
Generating Stations Purchase Power Agreement dated December 15, 1999 (PPA).
Exelon Generation is a subsidiary of Exelon Corporation (Exelon). Midwest is a
subsidiary of Edison Mission Energy and Edison International. Exelon Generation
has elected to exercise its call option on 1,265 MWs of the capacity for the
fourth contract year, 2003. This option exercise is for the year 2003 and has no
effect in 2002 because the 2002 supply plan is already in place. By exercising
the call, Exelon Generation will take the output of the following Midwest
generating units during 2003 at the contract price included in the PPA.

Waukegan Unit 6---100 MWs
Waukegan Unit 8---361 MWs
Fisk Unit 19---326 MWs
Crawford Unit 7---216 MWs
Will County Unit 3---262 MWs
Total ---1,265 MWs

Exelon Generation did not exercise its option on the 2,684 MWs of capacity at
the remaining option units and will not take the output from the following units
during 2003.

Will County Unit 1---156 MWs
Will County Unit 2---154 MWs
Joliet Unit 6---314 MWs
Joliet Unit 7---522 MWs
Powerton Unit 5---769 MWs
Powerton Unit 6---769 MWs
Total ---2,684 MWs

The exercise of the call option is pursuant to the terms of the PPA. Under the
PPA, during the fourth contract year, 2003, Exelon Generation contracted for
1,696 MWs of non-option capacity from Midwest with a call option on 3,949 MWs of
capacity. With the July 1 exercise of the call option, Exelon Generation will
take the 1,696 MWs of non-option capacity and 1,265 MWs of the option capacity
from Midwest. Exelon Generation retains its options to purchase the 1,265 MWs





from these plants in 2004, the final year of the PPA, as well as options
relating to Midwest's Collins and peaker units. Exelon Generation will not take
the remaining 2,684 MWs of option capacity for the year 2003. Providing reliable
service to customers in Illinois served by delivery subsidiary ComEd remains a
top priority of Exelon.

On June 20, 2002, Exelon provided earnings per share guidance of a 4.5% to 5.5%
compound annual growth rate (CAGR) off a 2001 base. That guidance included a
modeling assumption that one half of the 3,949 MW call option would be exercised
and that about one half would not be exercised. The cost savings incorporated in
Exelon's model total $120 million in 2003. With less than half of the options
being exercised, the cost savings may be incrementally higher than the $120
million included in the model. The actual cost savings achieved will be a
function of Exelon Generation's supply portfolio in 2003.

Flater at (312) 394-8354.

Linda C. Byus, CFA
Vice President Investor Relations
