     In the fourth quarter of 2004,  Exelon entered into three  forward-starting

     debt issuances.  The


                                       3



     swaps are  designated  as  cash-flow  hedges that  attempt to minimize  the
     variability of the future interest  expense  associated with changes in the
     three-month  LIBOR rate.  A table  summarizing  the  forward-starting  swap
     transactions  that were  entered  into in the third  quarter  is  presented
     below.

     In 2004, ComEd entered into fixed-to-floating  interest-rate swaps in order
     to maintain its targeted  percentage of variable-rate  debt associated with
     fixed-rate  debt  issuances in the  aggregate  amount of $240  million.  At
     December 31, 2004,  these  interest-rate  swaps,  designated  as fair-value
     hedges,  had an  aggregate  fair  market  value of $9 million  based on the
     present value difference  between the contract and market rates at December
     31, 2004. If these  derivative  instruments had been terminated at December
     31, 2004,  this  estimated  fair value  represents the amount that would be
     paid by the counterparties to ComEd.

15.  Investment Order - U-6B-2 (Financings Exempt from SEC Approval)

     o    Information that would be reported on a U-6B-2 for security  issuances
          by Utility  Subsidiaries  that are  exempt  from  approval  by the SEC
          (i.e., securities (long-term debt) approved by the State commissions).

          None.

     o    Securities issued by a Non-Utility Subsidiary (including  intercompany
          notes; but not money pool  transactions  which are reported under Item
          6)  that  are  exempt  from  approval  by the SEC  (i.e.,  Non-Utility
          Subsidiary securities issuances exempt under Rule 52).

          See Exhibit B.

16.  Financing Order - Future registration statements filed under the Securities
     Act of 1933 with  respect to  securities  that are  subject of the  instant
     application-



                                       9



     declaration  will be filed or  incorporated by reference as exhibits to the
     next certificate filed under rule 24.

         None.

17.  Financing  Order  -  A  copy  of  relevant  documents  (e.g.,  underwriting
     agreements,  indentures,  bank agreements) for the relevant quarter will be
     filed with, or  incorporated by reference from 1933 Act or 1934 Act filings
     in such Rule 24 Certificates.

         None.

18.  Financing Order - A computation in accordance with rule 53(a) setting forth
     Exelon's  "aggregate  investment" in all EWGs and FUCOs, its  "consolidated
     retained  earnings" and a  calculation  of the amount  remaining  under the
     Requested EWG/FUCO Authority (i.e., $4 billion).

     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 was granted  partial relief from this rule pursuant to the Financing
     Order,  which  provides for a Modified Rule 53 Test  applicable to Exelon's
     investments  in EWGs and FUCOs of $4,000  million.  At December  31,  2004,
     Exelon's  "aggregate  investment" (as defined in rule 53(a) under PUHCA) in
     all EWGs and FUCOs was approximately  $2,178 million and,  accordingly,  at
     December  31,  2004,  Exelon's  remaining  investment  capacity  under  the
     Modified Rule 53 Test was  approximately  $1,822  million.  At December 31,
     2004, Exelon's  "consolidated  retained earnings" (as defined in rule 53(a)
     under PUHCA) was $3,012 million.

19.  Financing Order - A breakdown showing Exelon's aggregate investment in each
     EWG or FUCO counting against the EWG/FUCO Authority.

     Pursuant  to a request  for  confidential  treatment  under rule  104(b) of
     PUHCA,  Exelon is  concurrently  filing in paper  format as  Attachment  1,
     certain  information   concerning  the  aggregate  investment  by  EWG/FUCO
     Project.

20.  Financing Order - Total  capitalization  ratio of Exelon, with consolidated
     debt to include all short-term  debt and  nonrecourse  debt of all EWGs and
     FUCOs.

     At December  31, 2004,  Exelon's  consolidated  capitalization  ratio as so
     calculated was 56% debt, 41% common equity,  2% short-tem,  and 1% minority
     interests  and preferred  securities.  (For these  purposes,  "consolidated
     debt" means all long-term debt,  long-term debt due within one year,  notes
     payable and other short-term obligations, including any short-term debt and
     non-recourse debt of EWG/FUCO Projects, to the extent normally consolidated
     under applicable financial reporting rules.)

21.  Financing Order - The market-to-book ratio of Exelon's common stock.

     At December 31, 2004, the market-to-book ratio of Exelon's common stock was
     3.13 to 1.00.

22.  Financing Order -  Identification  of any new EWG or FUCO counting  against
     the requested  EWG/FUCO Authority in which Exelon has invested or committed
     to invest during the preceding quarter.

     On January 31, 2005,  subsidiaries of Exelon Generation  completed a series
     of  transactions  that  resulted  in  Exelon  Generation's  exit  from  its
     investment in Sithe. Specifically, subsidiaries of Exelon Generation closed
     on the  acquisition  of  Reservoir's  50% interest in Sithe and the sale of
     100%  of  Sithe  to  Dynegy.  Prior  to  closing  on the  sale  to  Dynegy,
     subsidiaries of Exelon  Generation  received from Sithe  approximately  $65
     million  in  cash   distributions.   As  a  result  of  the  sale,   Exelon
     deconsolidated  from its balance sheet  approximately  $820 million of debt
     and was  released  from  approximately  $125  million  of  credit  support.
     Additionally, Exelon issued certain guarantees to Dynegy that will be taken
     into account in the final determination of the gain or loss on sale.

     On  October  13,  2004,  Sithe  transferred  all of  the  shares  of  Sithe
     International,  Inc.  and  its  subsidiaries  to  a  subsidiary  of  Exelon
     Generation  in exchange  for the  cancellation  of a $92  million  note and
     accrued interest.  Sithe  International,  through its  subsidiaries,  had a
     49.5% interest in two Mexican  business trusts that own the  Termoelectrica
     del Golfo ("TEG") and  Termoelectrica  Penoles ("TEP") power stations,  two
     230 MW petcoke-fired generating facilities in Tamuin, Mexico that commenced
     commercial  operations in the second quarter of 2004.  Both the TEG and TEP
     power stations are EWGs.

23.  Financing 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.

     Pursuant  to a request  for  confidential  treatment  under rule  104(b) of
     PUHCA,  Exelon is concurrently filing in paper format as Attachment 1 total
     earnings growth by EWG and FUCO project in the third quarter of 2004

24.  Financing  Order - A statement  of revenues and net income for each EWG and
     FUCO for the twelve months ending as of the end of that quarter.

     Pursuant  to a request  for  confidential  treatment  under rule  104(b) of
     PUHCA, Exelon is concurrently filing in paper format as Attachment 1, total
     earnings growth by EWG and FUCO project in the third quarter of 2004

25.  Investment  Order - Provide a copy of the  consolidated  balance  sheet and
     income statement for Ventures, Generation and Enterprises.
