         incorporated by reference as an exhibit to this certificate.

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

         See Form 8-K, Commission File Number 1-1401, dated April 16, 2004, with
         respect to PECO Energy Company entering into an underwriting  agreement

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

         applicable to Exelon's investments in EWGs and FUCOs of $4,000 million.

         53(a)  under  PUHCA)  in all EWGs and FUCOs  was  approximately  $1,939
         million,  and  accordingly,   at  June  30,  2004,  Exelon's  remaining
         investment  capacity under the Modified Rule 53 Test was  approximately
         $2,061  million.  At June 30,  2004,  Exelon's  "consolidated  retained
         earnings" (as defined in rule 53(a) under PUHCA) was $2,492 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

         At June 30,  2004,  Exelon's  consolidated  capitalization  ratio as so
         calculated  was: debt 61%,  common  equity 38%, and short-tem  debt 1%.

         long-term debt due within one year,  notes payable and other short-term
         obligations,  including any short-term  debt and  non-recourse  debt of
