Item 5. Other Events

On August 10, 2004, Exelon  Corporation  (Exelon)  announced that Exelon and the
U.S.  Department of Justice,  in close consultation with the U.S.  Department of
Energy (DOE),  have reached a settlement,  dated August 5, 2004, under which the
government will reimburse Exelon for costs associated with storage of spent fuel
at the  company's  nuclear  stations  pending  DOE  fulfilling  its  contractual
obligation to accept commercial spent nuclear fuel. Under the agreement,  Exelon
will receive $80 million  immediately in gross  reimbursements for storage costs
already incurred ($53 million net, after considering  amounts due from Exelon to
co-owners of certain  nuclear  stations),  with  additional  amounts  reimbursed
annually for future costs. If a national repository opens by 2010 and DOE begins
accepting spent nuclear fuel as the department has said, gross reimbursements to
Exelon would eventually total about $300 million (inclusive of the immediate $80
million gross  reimbursement  and net of  approximately  $43 million that Exelon
must  refund  to DOE  for  past  credits  to the  Nuclear  Waste  Fund).  Exelon
anticipates  that the  settlement  with the DOE will increase 2004 net income by
approximately  $0.05 per diluted share, $0.04 relating to reimbursement of costs
incurred in prior years and $0.01 relating to reimbursement of costs incurred in
2004.  The ongoing  impact of the settlement in future periods is expected to be
an increase to net income of approximately  $0.01 to $0.02 per diluted share per
year, depending on the timing of the costs incurred, which may not be consistent
from year to year.  In all cases,  reimbursements  will be made only after costs
are incurred and only for costs resulting from DOE delays in accepting the fuel.
The news release is attached to this report as Exhibit 99.
