     In the third  quarter of 2004,  Exelon  entered  into two  forward-starting
     interest rate swaps to hedge interest rate exposure  associated with future
     debt issuances.  The swaps are designated as cash-flow  hedges that attempt
     to minimize the variability of 


                                       3


     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
     September 30, 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 September
     30, 2004. If these derivative  instruments had been terminated at September
     30, 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-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  


                                       8


     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 September  30, 2004,
     Exelon's  "aggregate  investment" (as defined in rule 53(a) under PUHCA) in
     all EWGs and FUCOs was approximately  $2,143 million and,  accordingly,  at
     September  30,  2004,  Exelon's  remaining  investment  capacity  under the
     Modified Rule 53 Test was  approximately  $1,857 million.  At September 30,
     2004, Exelon's  "consolidated  retained earnings" (as defined in rule 53(a)
     under PUHCA) was $2,754 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 September 30, 2004,  Exelon's  consolidated  capitalization  ratio as so
     calculated was 58% debt, 40% common equity,  1% 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 September 30, 2004, the  market-to-book  ratio of Exelon's  common stock
     was 2.57 to 1.00.

                                       9


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  November  25,  2003,  Exelon  Generation  Company,   LLC  (Generation),
     Reservoir  Capital  Group  (Reservoir)  and Sithe  Energies,  Inc.  (Sithe)
     completed a series of  transactions  resulting in Generation  and Reservoir
     each  indirectly  owning a 50%  interest in Sithe.  Both  Generation's  and
     Reservoir's  50%  interests  in Sithe were  subject to put and call options
     that could result in either party owning 100% of Sithe.

     On September  29,  2004,  Generation  exercised  its call option to acquire
     Reservoir's 50% interest in Sithe for $97 million.  The closing of the call
     is subject to state and Federal regulatory approvals.

     On November 1, 2004,  Generation entered into an agreement to sell Sithe to
     Dynegy Inc. for $135 million in cash. Exelon expects that, prior to closing
     on the sale to Dynegy, it will receive from Sithe approximately $60 million
     in cash  distributions.  The sale will enable Exelon to deconsolidate  from
     its balance sheet  approximately  $836 million of debt  associated with the
     Independence generating plant.

     Sithe's remaining operating assets total approximately 1,350 MWs, including
     1,020  MWs in the  Independence  plant.  The sale  will not  include  Sithe
     International  Inc.,  which has been sold to a  subsidiary  of  Generation.
     Sithe  International,  Inc.  is the  entity  that  indirectly  owns a 49.5%
     interest  in the  Mexican  Business  Trusts,  which  own the  TEG  projects
     consisting  of two  gas-fired  plants in Mexico that  commenced  commercial
     operations in the second quarter of 2004.

     The sale of Sithe to Dynegy is  subject  to  Federal  and state  regulatory
     approvals.  The parties  anticipate  closing  early in the first quarter of
     2005.

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

                                       10


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

     Pursuant  to a request  for  confidential  treatment  under rule 104 (b) of
     PUHCA,  Exelon is  concurrently  filing in paper format as  Attachment 1, a
     consolidated   balance   sheet  and  income   statement  for  Ventures  and
     Enterprises  as of and for the quarter ended  September 30, 2004.  See Form

26.  Investment  Order - A narrative  description of Development  Activities and
     amount expended on Development Activities during the quarter just ended.

     PUHCA,  Exelon is  concurrently  filing in paper format as  Attachment 1, a
     description  of Development  Activities and amount  expended on Development
     Activities during the quarter ended September 30, 2004.
