                          INDEPENDENT AUDITORS' REPORT


To the Savings Plan Committee of the
GPU Companies Employee Savings Plan
For Employees Represented by IBEW System Council U-3:

We have audited the  accompanying  statements  of net assets  available for plan
benefits of GPU Companies  Employee  Savings Plan for Employees  Represented  by
IBEW System  Council  U-3(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.

                       GPU COMPANIES EMPLOYEE SAVINGS PLAN
              FOR EMPLOYEES REPRESENTED BY IBEW SYSTEM COUNCIL U-3
                          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 System  Council U-3 (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  System  Council  U-3  (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 November 1, 2001 the Company matched 80%, up from 75%
      prior to November 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,  mutual funds 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 System  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 for any reason.  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 age 70 1/2.
      Distributions  generally  are 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 9.20% for the period  January 1 through  June 30, 2001
      and 7.685% for the period July 1 through December 31, 2001.

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

            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.

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

            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
      Trusts  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  is 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
      (investment  custodian  bank) 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.

            Reclassifications:
            ------------------

      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:
      ---------------

      The Plan was  amended  and  restated  in  order to  incorporate  increased
      matching  contributions,  effective  January 1, 2001 and November 1, 2001.
      The Company  agreed to increase the match from 70% to 75% of an employee's
      contributions  up to 4% of base  compensation for the period of January 1,
      2001 through October 31, 2001 and additionally, increased the match to 80%
      of an  employee's  contributions  up to 4% of base  compensation,  for the
      period thereafter.

      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
