ITEM 9A.   CONTROLS AND PROCEDURES

(a)  Evaluation of Disclosure Controls and Procedures

         Each  registrant's  Chief Executive Officer and Chief Financial Officer
have  reviewed  and  evaluated  such   registrant's   disclosure   controls  and
procedures,  as defined in the Securities  Exchange Act of 1934 Rules  13a-15(e)
and  15d-15(e),  as of the end date  covered  by this  report.  Based  upon this
evaluation,  the respective Chief Executive  Officer and Chief Financial Officer
concluded  that  such  registrant's   disclosure  controls  and  procedures  are
effective,  despite the material weakness described below, because measures were
taken to correct the weakness during the fourth quarter of 2003.

         During  the  fourth  quarter of 2003,  management  identified  expenses
recognized  during the first three  quarters of 2003 related to activities  that
should have been recorded as capital  expenditures as a result of untimely table
updates in the  registrants'  automated work management  system and inconsistent
application of the allocation of costs to capital  projects in the  registrants'
work management system.

         Management  believes that this  condition,  which has been defined as a
material  weakness,  was  attributable to employee  training and process changes
that were not  uniformly  applied in  connection  with the  registrants'  recent
implementation of a new Enterprise  Resource  Planning system. As a result,  the
quarterly financial results for JCP&L, Penelec and TE have been restated in each
registrant's respective annual reports.

         As  discussed  below,   management  has  corrected  this  condition  by
strengthening the registrants' internal control procedures.

(b)  Changes in Internal Controls

         During the quarter ended December 31, 2003, management  implemented the
following measures to correct the condition discussed above:

         1.  Increased  training of field  employees  regarding  the proper
             accounting for capital and expense projects;

         2.  Established  procedures  to  ensure  that  tables  within  the
             registrants' automated work management system are updated on a
             timely basis; and

         3.  Reconfigured the registrants' automated work management system
             to  identify  the proper  allocation  of capital  and  expense
             projects.

         Except for the changes noted above,  there were no other changes in the
registrants' internal controls over the financial reporting that have materially
affected,  or are  reasonably  likely to  materially  affect,  the  registrants'
internal control over financial reporting.
