      Company, Pennsylvania Power Company, Jersey Central Power & Light
      Company, Metropolitan Edison Company and Pennsylvania Electric
      Company;
 
 2.
    Based on my
      knowledge, this annual report does not contain any untrue statement of a
      material fact or omit to state a material fact necessary to make the
      statements made, in light of the circumstances under which such statements
      were made, not misleading with respect to the period covered by this

 3.
    Based on my
      knowledge, the financial statements, and other financial information
      included in this annual report, fairly present in all material respects
      the financial condition, results of operations and cash flows of each
      registrant as of, and for, the periods presented in this annual
      report;
 
 4.
    Each
      registrant’s other certifying officer and I are responsible for
      establishing and maintaining disclosure controls and procedures (as
      defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal
      control over financial reporting (as defined in Exchange Act Rules
      13a-15(f) and 15d-15(f) for such registrant and we
have:
 
 a)
    designed such
      disclosure controls and procedures, or caused such disclosure controls and
      procedures to be designed under our supervision, to ensure that material
      information relating to such registrant, including its consolidated
      subsidiaries, is made known to us by others within those entities,
      particularly during the period in which this annual report is being
      prepared;
 
 b)
    designed such
      internal control over financial reporting, or caused such internal control
      over financial reporting to be designed under our supervision, to provide
      reasonable assurance regarding the reliability of financial reporting and
      the preparation of financial statements for external purposes in
      accordance with generally accepted accounting
  principles;
 
 c)
    evaluated the
      effectiveness of such registrant's disclosure controls and procedures and
      presented in this report our conclusions about the effectiveness of the
      disclosure controls and procedures, as of the end of the period covered by
      this report based on such evaluation; and
 
 d)
    disclosed in
      this report any change in such registrant's internal control over
      financial reporting that occurred during such registrant's most recent
      fiscal year that has materially affected, or is reasonably likely to
      materially affect, such registrant's internal control over financial
      reporting; and
 
 5.
    Each
      registrant’s other certifying officer and I have disclosed, based on our
      most recent evaluation of internal control over financial reporting, to
      such registrant’s auditors and the audit committee of such registrant’s
      board of directors (or persons performing the equivalent
    function):
 
 a)
    all
      significant deficiencies and material weaknesses in the design or
      operation of internal control over financial reporting which are
      reasonably likely to adversely affect such registrant's ability to record,
      process, summarize and report financial data; and
 
 b)
    any fraud,
      whether or not material, that involves management or other employees who
      have a significant role in such registrant’s internal control over
      financial reporting.
