                          INDEPENDENT AUDITORS' REPORT


To the Savings Plan Committee of the
GPU Companies Employee Savings Plan
For Employees Represented by IBEW Local 777:

We have audited the  accompanying  statements  of net assets  available for plan
benefits of GPU Companies  Employee  Savings Plan for Employees  Represented  by
IBEW Local 777 (the  "Plan") as of December  31, 2001 and 2000,  and the related
statements  of changes in net assets  available  for plan benefits for the years
then ended.  These  financial  statements are the  responsibility  of the Plan's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material  misstatement.  An audit also includes assessing
the accounting principles used and significant estimates made by management,  as
well as evaluating the overall financial statement presentation.  We believe our
audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the net assets available for plan benefits of the Plan as
of December 31, 2001 and 2000, and the changes in net assets  available for plan
benefits  for the years  then ended in  conformity  with  accounting  principles
generally accepted in the United States of America.

                          NOTES TO FINANCIAL STATEMENTS
                                     -------

1.    General Description of the Plan:
      -------------------------------

      The following  description of the GPU Companies  Employee Savings Plan for
      Employees  Represented  by IBEW Local 777  (Plan)  provides  only  general
      information  on the  provisions  of the Plan in effect as of December  31,
      2001.  Participants should refer to the Benefits Handbook,  Plan document,
      and prospectus for a more complete description of the Plan's provisions.

            General:
            -------

      The Plan is a defined  contribution  plan.  In general,  all GPU employees
      represented by IBEW Local 777 (Company) are eligible to participate in the
      Plan if he/she is  employed on a full-time  basis or if the  employee  has
      completed  at least 1,000 hours of service in a  consecutive  twelve-month
      period.

      The Plan is intended to qualify as a cash or deferred  profit-sharing plan
      under  Sections  401(a) and 401(k) of the  Internal  Revenue  Code.  It is
      subject to the provisions of the Employee  Retirement  Income Security Act
      of 1974 (ERISA).  A participant is eligible to transfer his/her account to
      an affiliated savings plan upon a change in his/her employment status.

      The Plan contains  additional  employer  contribution and employee savings
      features.  Participants may "rollover"  distributions  received from other
      qualified plans to the Savings Plan.

            Contributions:
            -------------

      The Plan provides two  contribution  options to a participant.  Subject to
      certain  limitations  set forth in the Plan, the participant may elect (1)
      to have his/her base compensation  reduced by an amount equal to any whole
      percentage  (before-tax  401(k)  contributions),  which is  contributed on
      behalf of the employee by the Company; and/or (2) to contribute by payroll
      deduction any whole percentage of base compensation (after-tax).

            Matching Program:
            ----------------

      The Company provides a matching contribution to the Plan on behalf of each
      participant,  except  certain  temporary  employees as defined in the Plan
      document. Effective May 1, 2001 the Company matched 75%, up from 70% prior
      to May 1, 2001, of a participant's aggregate contributions up to 4% of the
      participant's base compensation.

            Administration of Plan Assets:
            -----------------------------

      The Plan's assets,  which consist principally of stocks and bonds are held
      by the Trustee of the Plan.  Employer and  participant  contributions  are
      held and managed by the Trustee,  which invests cash  received,  reinvests
      interest and dividend income and makes distributions to participants.

            Administrative Expenses:
            -----------------------

      The  Company  absorbs a small  portion  of  administrative  expenses.  The
      majority of the administrative expenses,  primarily Investment and Trustee
      Fees,  are paid out of plan assets held in the GPU Companies  Master Trust
      (Trust).  Investment  gains in the Trust are shown net of these Investment
      and Trustee Fees.

            Investment Funds:
            ----------------

      The Plan provides investment options that are participant-directed,  which
      allows  participants  to choose  among  various  investment  alternatives.
      Participants  may change their investment  option at any time,  subject to
      certain limitations.

      Participants may elect to have their Plan accounts invested in one or more
      of the following investment options:

1.   General Description of the Plan, continued:
     -------------------------------

            Participant Accounts:
            --------------------

     Each   participant's   account  is  credited  with  the  participant's  own
     contributions and with the Company's matching  contributions.  Each account
     maintained  for a  participant  reflects the number of unitized  shares and
     their value for each mutual fund and for the  FirstEnergy  Stock Fund.  Any
     portion of a  participant's  account  balance  invested  in the Mutual Fund
     Window  reflects the number of shares and their value for each mutual fund.
     All income,  gain or loss  attributable to the investment of the balance of
     any account maintained for a participant is recorded to that account.

            Vesting:
            -------

     Participants are 100% vested at all times in their Plan accounts.

            Distributions and Withdrawals:
            -----------------------------

     A participant's Plan account balances become distributable upon termination
     of the  participant's  employment.  Distributions  of account  balances  in
     excess of $5,000 may be deferred, at the participant's  election, up to age
     70  1/2.  If  distribution  of a  participant's  account  balance  has  not
     otherwise  started,  it must begin by April 1st following the year in which
     the participant attained the age 70 1/2. Distributions generally are in the
     form of a single lump sum payment.  The Plan permits withdrawals of account
     balances in the event of financial hardship or disability as defined in the
     Plan.  A  complete  description  of the  Plan's  terms and  conditions  for
     distributions and withdrawals can be found in the Plan document.

            Loans to Participants:
            ---------------------

     The  Plan  provides  that  loans  may be made  to a  participant  from  the
     participant's  account balance subject to certain  conditions.  The minimum
     amount of each loan is $1,000 with the maximum  being  $50,000,  or certain
     lesser  amounts as described in the Plan.  Interest on the loan is credited
     to the participant's  account.  The loans are secured by the balance in the
     participant's  account.  Principal  and interest  are paid ratably  through
     monthly  payroll  deductions.  The rate is determined  periodically  by the
     Administrative  Committee based on current  commercial  rates. The interest
     rates for loans in excess of four years and ten  months  were 8.22% for the
     period  January 1 through  June 30,  2001 and 7.08% for the  period  July 1
     through  December 31, 2001. The interest rates for loans four years and ten
     months or less were 9.206% for the period  January 1 through  June 30, 2001
     and 7.685% for the period July 1 through December 31, 2001.

2.    Summary of Significant Accounting Policies:
      ------------------------------------------

            Plan Termination:
            ----------------

     The Company  reserves  the right at any time to modify,  suspend,  amend or
     terminate the Plan. However, the Company cannot do so in such a manner that
     would  cause or  permit  any part of the  Plan's  assets  to be used for or
     diverted to purposes other than for the exclusive  benefit of  participants
     or their beneficiaries.

            Basis of Accounting:
            -------------------

     The financial  statements of the plan are prepared under the accrual method
     of accounting.

            Valuation of Investments:
            ------------------------

     The amounts  shown herein as the  investment  in the GPU  Companies  Master
     Savings Plan Trust  reflect the fair value of the assets held in such Trust
     and the Plan's relative interest in the Trusts. The Plan's participation is
     measured at its value at the  beginning  of the  valuation  period plus net
     external cash flow (contributions,  distributions, etc.) experienced by the
     Plan during the  valuation  period.  Investment  income,  net realized gain
     (loss) on investments  and net unrealized  appreciation  (depreciation)  of
     investments  are  allocated  to each  participating  plan  based  upon  its
     accumulated monthly balance for each investment option (see Note 3).

     Investment  income from the GPU Companies Master Savings Plan Trust for the
     years ended  December 31, 2001 and 2000,  consists of interest and dividend
     income.   The  net  appreciation   (depreciation)  in  the  fair  value  of
     investments  consists  of  realized  gains  or  losses  and the  unrealized
     appreciation  (depreciation)  on  those  investments  in the GPU  Companies
     Master Savings Plan Trust.

     The fair  market  value of  assets  held by the  Trust  are  determined  as
     follows:  Stocks and bonds are valued at their closing quoted market prices
     on the last  business  day of the year.  Short-term  group  trust funds and
     insurance  contracts  are  valued  at  cost  plus  accrued  interest  which
     approximates market.

            Use of Estimates:
            ----------------

     The  preparation  of financial  statements  in conformity  with  accounting
     principles  generally accepted in the United States of America requires the
     plan  administrator  to make estimates and assumptions  that affect certain
     reported  amounts and disclosures.  Accordingly,  actual results may differ
     from those estimates.

     Certain  prior year amounts have been  reclassified  to conform to the year
     ended  December  31,  2001  presentation.  These  changes  had no impact on
     previously reported results of operations or net assets.

                                     -------


4.     Party-In-Interest Transactions:
       ------------------------------

       Certain  Plan  investments  are shares of mutual  funds  managed by State
       Street  Bank.  State  Street  Bank is the trustee as defined by the Plan.
       Therefore, these transactions qualify as party-in-interest transactions.

5.     Tax Status:
       ----------

       The Plan obtained its latest determination letter on February 4, 1998, in
       which  the  Internal  Revenue  Service  stated  that  the  Plan,  as then
       designed,  was in  compliance  with the  applicable  requirements  of the
       Internal  Revenue  Code.  The Plan has been amended  since  receiving the
       determination letter.  However, the plan administrator and the plan's tax
       counsel  believes that the Plan is currently  designed and being operated
       in compliance with applicable  requirements of the Internal Revenue Code.
       Therefore,  no provision for income taxes has been included in the Plan's
       financial statements.

6.     Plan Amendments:
       ---------------

       Effective  May 1, 2001,  the Plan was  amended  and  restated in order to
       incorporate  an increased  matching  contribution.  The Company agreed to
       increase the match from 70% to 75% of an employee's  contributions  up to
       4% of base compensation.

       The Plan was further  amended,  effective  October 1, 2001 to incorporate
       FirstEnergy  Merger  Provisions.  At the  effective  time  of the  merger
       between GPU Company and FirstEnergy Corporation,  all shares of GPU Stock
       held in the GPU Stock Fund were automatically converted into the right to
       receive the merger  consideration with respect to such shares. The merger
