     PUHCA)  in all  EWGs  and  FUCOs  was  approximately  $2,076  million,  and
     accordingly,  at September 30, 2002, Exelon's remaining investment capacity
     under  the  Modified  Rule 53 Test was  approximately  $1,924  million.  At
     September 30, 2002, Exelon's  "consolidated  retained earnings" (as defined
     in rule 53(a) under the PUHCA) was $1,381 million.
