Item 8.  Exhibits.

      The  exhibits  listed  on the  accompanying  Exhibit  Index  are  filed or

      With respect to the unaudited  financial  information of FirstEnergy Corp.
for the  three-month  period ended March 31, 2002  incorporated  by reference in
this Registration Statement,  PricewaterhouseCoopers LLP reported that they have
applied  limited  procedures in  accordance  with  professional  standards for a
review of such  information.  However,  their separate report dated May 15, 2002
incorporated by reference herein, states that they did not audit and they do not
express an opinion on that unaudited  financial  information.  Accordingly,  the
degree of reliance on their report on such  information  should be restricted in
light   of   the   limited   nature   of   the   review   procedures    applied.
PricewaterhouseCoopers LLP is not subject to the liability provisions of Section
11 of the  Securities  Act of 1933 for their report on the  unaudited  financial
information  because  that  report  is  not  a  "report"  or  a  "part"  of  the
registration  statement  prepared or  certified  by  PricewaterhouseCoopers  LLP
within the meaning of Sections 7 and 11 of the Act.
