                         Report of Independent Auditors


To the Participants and Savings Plan Committee of the
FirstEnergy Corp. Savings Plan


In our opinion, the accompanying statements of net assets available for plan
benefits and the related statements of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
plan benefits of the FirstEnergy Corp. Savings Plan (the "Plan") at December 30,
2002 and 2001, 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. 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 of these
statements in accordance with auditing standards generally accepted in the
United States of America, which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets
(held at end of year) and reportable transactions are presented for the purpose
of additional analysis and are not a required part of the basic financial
statements but are supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. These supplemental schedules are the
responsibility of the Plan's management. The supplemental schedules have been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

FirstEnergy Corp. Savings Plan

Notes to Financial Statements
December 30, 2002 and 2001
-----------------------------------------------------------------------------



1.   Description of the Plan

     The FirstEnergy Corp. Savings Plan (the "Plan") provides eligible
     employees of FirstEnergy Corp. ("FirstEnergy" or "FE") and its
     subsidiaries, collectively referred to as the "Companies", a mechanism
     through which they can save and invest part of their income on a tax
     deferred basis at regular intervals. Additionally, the Companies
     currently match employee contributions with shares of FirstEnergy common
     stock (see Note 7) held in the Employee Stock Ownership Plan ("ESOP").
     However, according to the Plan, the Companies can alternatively make the
     contributions in cash. Employees may invest their contributions in other
     investment options (the "Funds") and all contributions made to employees'
     accounts are fully and immediately vested in the Plan. The purpose of the
     Plan is to encourage employees to adopt a regular savings program and to
     provide additional security for retirement. The following is a brief
     description of the Plan and is provided for general information purposes
     only. Employees should refer to the Plan documents for more complete
     information.

     The Plan is a qualified profit-sharing plan under Section 401(a) of the
     Internal Revenue Code of 1986, as amended (the "Code"), and provides for
     salary reduction contributions under Section 401(k) of the Code. In
     general, plans established pursuant to Section 401(k) of the Code permit
     eligible employees to defer current federal and, subject to applicable
     laws, state and local income taxes on the portion of their current
     compensation represented by the amount of the salary reduction elected.
     The amounts, as elected by the employees, are contributed to the Plan by
     the Companies through payroll deductions.

     The Plan is subject to Title I of the Employee Retirement Income Security
     Act of 1974 ("ERISA") but not Title IV as it is an "individual account
     plan". Title I establishes reporting and disclosure requirements, minimum
     standards for participation, vesting and benefit accrual, prohibitions
     governing the conduct of fiduciaries and provides that ERISA pre-empts
     other federal, state and local statutes relating to employee benefits.
     The protective benefits of Title IV which relate to insuring pension
     benefits by the Pension Benefit Guaranty Corporation are not applicable
     to individual account plans.

     Every permanent FirstEnergy employee is eligible to become a participant
     in the Plan, herein referred to as "employee" or "Participant",
     immediately at commencement of employment.

     Employees may participate in one or more of the Funds through deferral of
     compensation. The choice of investments (except the Companies' matching
     contributions, which are in the form of FirstEnergy common stock) is the
     responsibility of the individual employee. Transfers between funds are
     the responsibility of the employee and may be made on a daily basis.

     Securities in the ESOP Account
     The ESOP purchased a total of 10,654,114 shares of Ohio Edison ("OE")
     common stock from November 1990 to December 1991 for the purpose of
     funding the Companies' matching contribution to the Plan. On November 8,
     1997, pursuant to the merger of OE and Centerior Energy Corporation that
     created FirstEnergy ("Merger"), shares of OE common stock were converted
     into shares of FirstEnergy common stock on a one-for-one basis.

     The Plan borrowed $200 million, referred to herein as the "ESOP Loan", at
     a rate of 10% from OE to fund the purchase of the stock. The ESOP Loan is
     collateralized by the unallocated FirstEnergy

                                       4

     common stock acquired with the proceeds of the ESOP Loan. The ESOP Loan is
     expected to be repaid by December 2005.  Interest  payments on the loan are
     made  annually.  Additionally,  principal  payments  may be made  sooner if
     additional shares of FirstEnergy  common stock are needed for distributions
     to  Participants.  At December 30, 2002 and 2001, the ESOP Loan balance was
     $125,850,000 and $149,550,000, respectively.


     Requirements for maturing long-term debt are as follows:


             2003 ...........    $29,300,000
             2004 ...........     35,700,000
             2005 ...........     60,850,000
                                ------------

                                $125,850,000

     ESOP Allocation
     As principal and interest payments are made on the ESOP Loan, shares of
     FirstEnergy common stock are released from the ESOP Unallocated Fund to
     the ESOP Allocated Fund where they are made available for contribution to
     Participants' accounts. The Plan made interest payments of $14,955,000 in
     2002 and $35,100,000 in 2001, which released 353,756 shares in 2002 and
     812,272 shares in 2001. In December 2002, a principal payment of
     $23,700,000 was made which led to the release of 560,617 shares. In
     December 2001, a principal payment of $18,700,000 was made which led to
     the release of 442,343 shares.

     The Companies' matching contribution to each Participant's account is
     computed the Thursday following the end of each pay period based on the
     Companies' matching contribution percentages (see Note 7) and on the
     quoted market price of FirstEnergy common stock when contributed. During
     2002 and 2001, there were 688,740 and 548,888 ESOP shares, respectively
     contributed to Participants' accounts. In 2002 and 2001, respectively,
     207,989 and 197,077 ESOP shares were realized related to the reinvestment
     of dividends on the ESOP shares.

     At December 30, 2002 and December 30, 2001, there were 3,646,967 and
     4,561,340 shares, respectively, held in the ESOP Unallocated Fund at
     market values of $120,240,502 and $159,555,675, respectively, and
     5,690,142 and 5,041,555 shares, respectively, held in the ESOP Allocated
     Fund at market values of $187,604,005 and $176,352,004. The market value
     of the ESOP common stock is measured by the quoted market price.

     PAYSOP
     A component of the Plan consists of a qualified payroll-based tax credit
     employee stock ownership plan ("PAYSOP") under Section 401(a) and Section
     501(a) of the Code.

     Under the Economic Recovery Tax Act of 1981, effective January 1, 1983,
     tax credits were based upon eligible employee compensation. The
     regulation permitted the Companies to contribute to the fund a maximum of
     one-half of one percent of the aggregate compensation of eligible
     employees and claim a tax credit on its consolidated federal income tax
     return equal to this amount. The amounts allocated to eligible employees
     were based upon the proportion of their wages and salaries (to a maximum
     of $100,000) to the wages and salaries of total employees for the year.

                                       5




FirstEnergy Corp. Savings Plan

Notes to Financial Statements
December 30, 2002 and 2001
-----------------------------------------------------------------------------


     The Tax Reform Act of 1986 eliminated the PAYSOP tax credit with respect
     to compensation earned in 1987 or later years. As a result, the Companies
     have not contributed to the PAYSOP since the 1986 contribution other than
     for the reimbursement of PAYSOP administrative expenses.

     On November 8, 1997, pursuant to the Merger, shares of OE common stock
     held in the PAYSOP were converted into shares of FirstEnergy common stock
     on a one-for-one basis.

     Dividends are paid annually to Participants in the PAYSOP. The market
     value of the common stock in the PAYSOP is measured by the quoted market
     price. As of February 11, 2002, dividends will be payable quarterly to
     Participants and Participants will also have the option to reinvest
     dividends back into the PAYSOP Fund. The market value of the Paysop Fund
     was $3,114,477 and $3,301,054 at December 30, 2002 and 2001,
     respectively.


2.   Summary of Accounting Policies

     The financial statements have been prepared on the accrual basis of
     accounting.

     The Plan presents, in the Statements of Changes in Net Assets Available
     for Plan Benefits, the net appreciation (depreciation) in the fair value
     of its investments, which consists of realized gains or losses and
     unrealized appreciation or depreciation. All investment management fees
     are deducted from investment income. The market value of the Fund is
     measured at the market value per share determined by the investment
     manager except for funds A, B, L and N. See footnote 4 for the
     methodology used to determine fair value for each of these funds.

     The preparation of financial statements in conformity with accounting
     principles generally accepted in the United States of America requires
     management to make estimates and assumptions that affect the amounts
     recorded in the financial statements and accompanying notes. Actual
     results may differ from these estimates.

     The Companies pay all expenses associated with administering the Plan,
     including State Street Bank & Trust Company ("Trustee") fees and
     brokerage commission on purchases and transfers between the funds.


3.   Plan Termination

     Although the Companies have not expressed any intent to do so, the
     Companies reserve the right to discontinue or terminate the Plan at any
     time. If the Plan should be terminated, in whole or in part, Participants
     will be entitled to withdraw the full value of their accounts, to the
     extent allowed by law.


4.   Descriptions of Funds

     The following are brief descriptions of the Funds currently available to
     Participants at December 30, 2002:

                                       6




FirstEnergy Corp. Savings Plan

Notes to Financial Statements
December 30, 2002 and 2001
-----------------------------------------------------------------------------

     Fund A - Company Common Stock Fund
     This Fund consists entirely of shares of FirstEnergy common stock. The
     Fund provides an opportunity for employees to increase their common
     ownership stake in FirstEnergy. The objective for this Fund is the growth
     of capital through both appreciation and dividend income. The Fund also
     holds the Companies' pre-ESOP matching contribution in FirstEnergy common
     stock. The common stock is purchased by the Trustee on the open market.
     The market value of the common stock is measured by the quoted market
     price.

     Fund B - Capital Preservation Fund
     This Fund consists of guaranteed fixed income contracts issued by
     insurance companies and banks, collateralized mortgage obligations, and
     short-term money market instruments. These contracts guarantee interest
     for a fixed period and the principal amount of all investments. The
     market value of the Capital Preservation Fund is measured at the contract
     value as determined by the insurers and banks.

     Fund C - S&P 500 Index Fund
     This Fund is a common/collective trust investing in the S&P 500 stocks.
     The objective of this Fund is the growth of capital through both
     appreciation and dividend income.

     Fund D - Small Cap Value Fund
     This Fund invests primarily in securities of well-financed small cap
     companies at a substantial discount to what the manager believes are
     takeover values. The manager is EQSF Advisors, Inc. and the mutual fund
     name is Third Avenue Value. The objective of the Fund is to match or
     exceed the returns of the Russell 2000 Value Index over time.

     Fund E - Large Cap Value Fund
     The Fund seeks long-term capital appreciation and income by focusing on
     domestic large company equities that are selling at modest prices to
     earnings multiples. Shares are usually held for the long-term. Only
     extreme valuations or major changes to a company's fundamentals will
     trigger a sale. The portfolio manager is Davis Selected Advisors, L.P.
     and the mutual fund name is Selected American Fund. The performance
     objective is to match or exceed the S&P/Barra Large Cap Value Index over
     time.

     Fund F - Mid Cap Value Fund
     The Fund seeks long-term capital appreciation by investing in mid-sized
     companies that are less closely monitored by the investment community as
     evidenced by low institutional ownership and analyst coverage. The goal
     is to find well-managed companies that have sustainable growth prospects
     but that are selling at prices below their private market value. The
     manager believes that these factors may cause shares to be undervalued.
     The manager may sell a stock when its price no longer compares favorably
     with the company's private market value. The portfolio manager is Strong
     Capital Management and the mutual fund name is Strong Opportunity Fund.

7.   Contributions

     Employer Contributions
     The Companies pay a matching contribution of 50% on the first 6% of
     compensation contributed by an employee. In addition, the Companies may
     designate a number of performance objectives and contribute for each
     objective achieved, an additional $.05, up to a maximum of $.25, on each
     $1.00 of the first 6% of compensation contributed by an employee. The
     Companies' contributions are always invested in FirstEnergy common stock.

     The Companies' contributions have been pre-funded by the FirstEnergy
     common stock held by the ESOP Unallocated Fund. These shares of
     FirstEnergy common stock earn dividend income and are subject to
     unrealized appreciation and depreciation as the market value of the
     FirstEnergy common stock fluctuates. The dividend income serves to pay
     the ESOP Loan and related interest, which results in the release of
     shares to the ESOP Allocated Fund as the Companies' matching
     contribution. To the extent dividend income is not sufficient to pay the
     ESOP Loan and interest, the Companies will contribute cash which is
     reflected as employer contributions in the Statements of Changes in Net
     Assets Available for Plan Benefits. No such contributions were made in
     2002 or 2001. Effective February 11, 2002, Participants who are at least
     55 years of age with ten years in the ESOP are provided the ability to
     diversify a portion of their company matching portfolio. The first
     participants to elect this option became eligible in 2002.

     Employee Contributions

     During 2001, employees could invest between 1% and 16% of their salary in
     the Plan. Effective January 1, 2002, the maximum contribution rate was
     increased from 16% to 20%. Employee contributions may be made on a
     before-tax and/or after-tax basis. Under the before-tax option, deposits
     are deducted from current taxable income but are taxable when they are
     withdrawn from the Plan. The Tax Reform Act of 1986 limited the maximum
     annual before-tax contribution to $11,000 for 2002 and $10,500 for 2001.
     Participants who are at least 50 years of age can elect to defer an
     additional $1,000 annually. Prior to age 59-1/2, an active employee may
     withdraw before-tax deposits only under certain hardship conditions as
     defined in the Plan document.

     Employees may make rollover contributions to the Plan of funds held in
     other tax-qualified plans which the employee was a participant of prior
     to becoming employed by the Companies. The rollover contributions must be
     the result of a qualified total distribution from another tax-qualified
     plan and must be contributed to the Plan within 60 days after
     distribution to the employee.

     Both employer and employee contributions under the Plan are held in a
     trust fund with the Trustee. Employees may choose to invest their
     contributions in Funds A, B, C, D, E, F, G, H, I, J, K or M (see Note 4)
     which are offered by the Plan. Employees may also elect to borrow from
     their before-tax accounts for certain approved purposes (Fund L).


8.   Tax Considerations

     The Plan is exempt from federal, state and local income taxes. The Plan
     received a favorable determination letter, which was dated March 24,
     2003. The federal, state and local income tax

Notes to Financial Statements
December 30, 2002 and 2001
-----------------------------------------------------------------------------


     treatments of distributions from the Plan depend upon when they are made
     and their form. The withdrawal of the principal amount of a Participant's
     after-tax contribution is not, however, subject to tax. For tax years
     beginning after December 31, 1986, the Tax Reform Act of 1986 requires that
     an additional tax of 10% be applied to employee withdrawals from the Plan
     prior to death, disability, attainment of age 59-1/2, or under certain
     other limited circumstances.

     In the case of withdrawal by a Participant employed by the Companies
     prior to the attainment of age 59-1/2, the excess of the value of the
     withdrawal over the total amount of the Participant's after-tax
     contributions, is taxable at ordinary income tax rates. The value of the
     Companies common stock withdrawn is considered to be its fair value on
     the date it is withdrawn.

     In the case of a distribution that qualifies as a lump-sum distribution
     upon a Participant's termination of employment with the Companies or
     after attaining the age of 59-1/2, only the excess of the value of the
     lump sum distribution over the amount of the Participant's after-tax
     contributions to the Plan (less withdrawals) is taxable at ordinary
     income tax rates. In determining the value of the lump-sum distribution,
     the FirstEnergy common stock distributed in-kind or in cash shall be
     valued at fair value on the date it is withdrawn.


9.   Conversion Transfers

     On April 30, 2002, the FirstEnergy Corp. 401(K) Retirement Savings Plan
     for IBEW Employees at the Beaver Valley Nuclear Power Plant was merged
     into the Plan. Net assets with a value of $18,949,093 were transferred to
     the Plan.


10.  Subsequent Event

     Effective January 1, 2003, the GPU Non-Bargaining Savings Plan
     participants were transferred into the Plan.


11.  Guaranteed Investment Contracts

     The Plan holds fully benefit-responsive guaranteed investment contracts
     ("GICs"), which are presented at contract value in the Statements of Net
     Assets Available for Plan Benefits as previously stated in Note 4. The
     fair values of the GICs at December 30, 2002 and 2001 were $209,520,197
     and $169,892,523, respectively. The average yield of the contracts was
     5.36% and 5.97% for the years 2002 and 2001, respectively. The crediting
     interest rate as of December 30, 2002 and 2001 was 4.87% and 5.51%,
     respectively. The Capital Preservation Fund is measured at the contract
     value as determined by the insurers and banks and no valuation reserve in
     relation to the contract value is deemed necessary. The GICs in the Plan
     are of various types and have zero minimum crediting interest rates.
     There are fixed crediting interest rates and variable crediting interest
     rates that reset on a monthly or quarterly basis.
