      "aggregate  investment" in all EWGs and FUCOs, its "consolidated  retained
      earnings" and a calculation  of the amount  remaining  under the Requested
      EWG/FUCO Authority.

      Rule  53(a)  provides  that  a  registered  holding  company's   aggregate
      investment in EWGs and FUCOs may not exceed 50% of its retained  earnings.

      Exelon's investments in EWGs and FUCOs of $4,000 million. At September 30,

      PUHCA)  in all  EWGs and  FUCOs  was  approximately  $2,758  million,  and
      accordingly, at September 30, 2003, Exelon's remaining investment capacity
      under the  Modified  Rule 53 Test was  approximately  $1,242  million.  At

      in rule 53(a) under PUHCA) was $2,245 million.

4.    Order - Analysis  of the growth in  consolidated  retained  earnings  that
      segregates total earnings growth of EWGs and FUCOs from that  attributable
      to other subsidiaries of Exelon.

      PUHCA,  Exelon is  concurrently  filing in paper format as  Attachment  1,

On October 3, 2003, Genco announced 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 on September 11, 2003 that it intended to buy British Energy's share of AmerGen. Under the AmerGen limited liability company operating agreement between Exelon and British Energy, either could exercise a "right of first refusal" by matching any bona-fide third-party offer agreed to by the other party. AmerGen owns the Clinton Power Station in Central Illinois, Three Mile Island Unit 1 near Harrisburg, Pennsylvania and the Oyster Creek Generating Station on the New Jersey shore. The three stations represent about 2,500 megawatts of generating capacity. The AmerGen purchase is expected to be completed in the first half of 2004. See Exelon Corporation Form 8-K filed on October 3, 2003. 22
