STOCK INVESTMENT PLAN
10,000,000 SHARES
COMMON STOCK
(PAR VALUE $.10 PER SHARE)

The FirstEnergy Corp. Stock Investment Plan (the "Plan") provides a way for shareholders and employees of FirstEnergy Corp. (the "Company") and its subsidiaries, as well as others, to purchase shares of the Company's common stock. Participants in the Plan may:
- Reinvest all or a portion of cash dividends paid on shares of the Company or its subsidiaries registered in their names, as well as any common stock credited to their Plan accounts, to purchase shares of Company common stock.
- Make an initial investment in Company common stock with a cash payment of at least $250 or, if already a shareholder or employee of the Company or its subsidiaries, make an investment in Company common stock with optional cash investments at any time of at least $25 per payment. Cash investments are limited to a maximum of $100,000 per calendar year.
- Receive certificates for whole shares of common stock credited to their Plan accounts upon request.
- Deposit certificates representing Company common stock into the Plan for safekeeping.
- Sell shares of common stock credited to their Plan accounts through the Plan. Cash dividends and cash investments under the Plan will be used to purchase shares of Company common stock which, at the option of the Company, will be either newly issued shares or will be purchased on behalf of Plan participants in the open market by an Independent Agent appointed by the Company. The price of shares purchased in the open market under the Plan will be the weighted average price paid by the Independent Agent for the shares over the purchase period. The price of newly issued shares acquired under the Plan will be the average of the high and low prices of the Company's common stock as reported in The Wall Street Journal's report of New York Stock Exchange Composite Transactions for the investment date. In both cases, the purchase price will include a transaction fee which is not expected to exceed $.09 per share. The Company will receive all of the proceeds resulting from the purchase of newly issued shares under the Plan. The Company does not receive any part of the proceeds resulting from the purchase of shares in the open market under the Plan other than a portion of the related transaction fees designed to cover administrative costs. The cost to the Company to implement the Plan is estimated to be $150,000. Some or all of these costs may be recovered through the transaction fees.

Fees payable by a Plan participant will be added to the purchase price for shares purchased, and deducted from the selling price for shares sold, under the Plan. (See Questions 15 and 22.)


To the extent required by applicable law in certain jurisdictions, including Arizona, Florida, Idaho, Maine, New Jersey and North Dakota, shares of common stock offered under the Plan to persons who are not already holders of Company common stock will be offered only through a registered broker/dealer in such jurisdictions.


This Prospectus describes the provisions of the Plan and should be retained by participants for future reference. The Company's common stock is listed on the New York Stock Exchange under the symbol "FE".
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

DESCRIPTION OF THE PLAN

The following questions and answers describe the terms and conditions of the Plan. We suggest that you keep this Prospectus for future reference.

PURPOSE

1. Q. What is the purpose of the Plan?

A. The purpose of the Plan is to provide shareholders and employees of the Company and its subsidiaries, as well as others, a way to purchase shares of the Company's common stock. Purchases can be made by investing cash and/or reinvesting cash dividends.

ADMINISTRATION

2. Q. Who administers the Plan?

A. The Company will administer the Plan. This will include keeping the Plan records and serving as custodian for shares held in the Plan. If the Company elects to meet the purchase requirements of participants through purchases of shares of common stock in the open market, funds for investment will be promptly deposited into an escrow account for the benefit of Plan participants. An Independent Agent appointed by the Company will then act on behalf of participants in buying such shares. The Independent Agent, or such other registered securities broker designated by the Company, will sell Plan shares on behalf of participants.

The Company reserves the right to interpret and regulate the Plan as deemed necessary or desirable. Neither the Company nor its Independent Agent will be liable for any act done in good faith or for any omission to act in good faith, including, without limitation, any claim of liability arising out of failure to close a participant's account upon the participant's death prior to receipt of written notice of such death, or with respect to the prices at which shares of common stock are purchased or sold for the participant's account and the times when such purchases and sales are made, or with respect to any loss or fluctuation in the market value after the purchase or sale of such shares. However, the Company shall not be relieved from any liability imposed under any federal, state or other applicable securities law that cannot be waived.

3. Q. Who should I contact with questions concerning the Plan?

A. You may call the Company's Investor Services toll-free at 1-800-736-3402.


Or, you may write to the following address:

FIRSTENERGY CORP.
INVESTOR SERVICES
76 S. MAIN STREET
AKRON, OH 44308-1890

PARTICIPATION

4. Q. Who is eligible to participate in the Plan?

A. All registered shareholders and employees of the Company and its subsidiaries are eligible to participate. In addition, any person or entity who is not a registered shareholder or employee is eligible to participate provided that in the case of citizens or residents of a country other than the United States, its territories and possessions, their participation would not violate local laws applicable to the Company, the Plan or the participant.

5. Q. How do I enroll in the Plan or change my method of participation?

A. SHAREHOLDERS -- Current registered shareholders can enroll by completing and signing a Plan Enrollment Form.

EMPLOYEES -- Employees can enroll by completing and signing a Plan Enrollment Form/Payroll Deduction Authorization Form (Form 133, available from department secretary). If voluntary payroll deductions are not desired, this form must be accompanied by a cash payment.

OTHER PERSONS OR ENTITIES -- If you are not a registered shareholder or employee, you can enroll by making an initial cash investment of at least $250 and completing and signing a Plan Enrollment Form. The Enrollment Form requires each person to certify that he/she is of legal age and to provide information necessary to open an account, such as the stock registration desired, address and taxpayer identification number.

You may change the method of participation at any time by completing and signing another Plan Enrollment Form. In the case of an employee who is using payroll deductions to invest in the Plan, the amount of the deduction can be changed or canceled by completing and signing another Plan Enrollment Form/Payroll Deduction Authorization Form.

6. Q. What dividend payment options are provided under the Plan?

A. The Plan provides complete flexibility in regard to how dividends are paid. You are asked to provide payment instructions by completing both Parts (A) and (B) of the Dividend Reinvestment and Payment Instructions
Section of the Plan Enrollment Form. Part (A) contains payment instructions for shares that are currently held, or may be held in the future, by you in certificate form. Part (B) contains payment instructions for shares that are currently held, or may be held in the future, by the Company in an account for you. Dividend payment options are as follows:

REINVEST DIVIDENDS ON ALL SHARES -- All dividends are reinvested to purchase shares of Company common stock.

PAY CASH DIVIDENDS ON ALL SHARES -- All dividends are paid in cash. (See below for direct deposit information.)

PAY CASH DIVIDENDS ON PORTION OF SHARES -- You may elect to have a portion of dividends paid in cash and reinvest the remaining dividends to purchase shares of Company common stock by selecting the number of shares, the percent, or the dollar amount of dividends to be paid in cash. (See below for direct deposit information.)

4

If you elect to receive all or a portion of your dividends in cash, your cash dividends may be deposited directly into your checking, savings or credit union account at any financial institution that accepts electronic direct deposits. Receiving your payments by direct deposit ensures that the funds will be deposited into your bank account on the payment date. If you are interested in direct deposit of dividends, you should complete the appropriate section on the Enrollment Form or call Investor Services for a Direct Deposit Authorization Form.

7. Q. When must my Plan Enrollment Form be received by the Company?

A. For dividends to be reinvested, your Enrollment Form must be received by the Company on or before the record date for the dividend payment; otherwise, reinvestment of dividends will start with the next succeeding dividend payment. The dividend record and payment dates for preferred stock dividends vary and can be obtained by contacting the Company. The dividend record and payment dates for common stock dividends, which must be declared by the Board of Directors, are expected to be as follows:

Record dates -- Fifth business day of February, May, August, November Payment dates -- March 1, June 1, September 1, December 1

For initial cash investments, a properly completed Enrollment Form and the initial cash payment must be received by the Company before a cash Investment Date, which will be the 1st and 15th day of each month. Otherwise, the investment will be made on the next succeeding cash Investment Date.

DIVIDEND REINVESTMENT

8. Q. What is meant by dividend reinvestment?

A. If you have elected to reinvest all or a portion of your dividends, the Company will take those dividends and purchase shares of Company common stock for you. The amount reinvested will be reduced by any amount that is required to be withheld under any applicable tax or other statutes and by applicable transaction fees. See the "Purchases" section for more detailed information.

CASH INVESTMENTS

9. Q. Who is eligible to make cash investments?

A. All persons and entities that are eligible to participate in the Plan are eligible to make cash investments. See Question 4 for Plan eligibility requirements.

10. Q. What are the minimum and maximum cash investments?

A. If you are not a registered shareholder or employee of the Company or its subsidiaries, the initial cash investment must be at least $250.

If you are a registered shareholder or employee of the Company or its subsidiaries, the minimum cash investment is $25 per payment; however, for employees who elect to use payroll deduction to make cash investments, the minimum deduction is $10.

The maximum amount of cash investments is $100,000 per calendar year.

5

11. Q. How do I make a cash investment?

A. If you are not a current Plan participant, you must enclose a check with your Plan Enrollment Form.

If you are a current Plan participant, you can make a cash investment by sending a check or by signing up for automatic electronic investments as discussed below. When sending a check, you should attach a cash investment form which is attached to your Plan statements. You may also send a check without a cash investment form; however, your stock registration and tax identification number should be included on your check for account identification purposes, along with a cover letter requesting that the check be used to purchase common stock of the Company. If you are sending a cash payment to open a new account, you must send a letter of instruction providing the name, address and tax identification number (include an IRS Form W-9) for the new account.

All checks should be made payable to "FirstEnergy Corp." and sent to FirstEnergy Investor Services at 76 South Main Street, Akron, OH 44308-1890. For the protection of participants, the Company discourages sending cash or endorsed second-party checks. Cash investments received from foreign shareholders must be in United States dollars.

You may authorize monthly automatic electronic cash investments by completing the appropriate section on the Enrollment Form or by completing an Automatic Electronic Investment Authorization Form available from Investor Services. This enables you to make regular investments, if you choose, without the inconvenience of writing and mailing checks. If you authorize automatic electronic cash investments, funds will be withdrawn from your bank or credit union account around the 25th day of each month and will be invested on the next Investment Date following the withdrawal. Your bank, savings association or credit union must be a member of the National Automated Clearinghouse Association. You may change the amount automatically withdrawn or the financial institution at any time by completing a new Automatic Electronic Investment Authorization Form, and you may stop automatic electronic cash investments by notifying Investor Services in writing.

Cash investments, pending purchase of common stock through the Plan, will be credited to your Plan account and held in a bank account which will be separated from funds of the Company. No interest will be paid by the Company on cash held for investment.

You may request the return of a cash investment upon written request received by the Company not later than 48 hours prior to the applicable investment date.

INVESTMENT DATES

12. Q. When are the Investment Dates for Plan purchases?

A. Investment Dates for reinvested dividends are the dividend payment dates.
Payment dates for common stock dividends are expected to be March 1, June 1, September 1 and December 1. Payment dates for preferred stock can be obtained by contacting the Investor Services.

Investment Dates for cash investments are the 1st and 15th day of each month. Cash investments must be received by the Company by the business day before the Investment Date in order to be

6

invested on such Investment Date. Otherwise, the cash investments will be held by the Company and invested on the next Investment Date.

In order to receive dividends on shares of common stock purchased with cash investments, the shares must be purchased on an Investment Date prior to the dividend record date. Record dates for common stock dividends are expected to be the fifth business day of February, May, August and November.

PURCHASES

13. Q. What is the price of shares purchased under the Plan?

A. Cash dividends and cash investments will be used to purchase shares of the Company's common stock which, at the option of the Company, will be either newly issued or will be purchased on behalf of Plan participants in the open market by an Independent Agent appointed by the Company.

When shares are purchased in the open market, the purchase price per share will be the weighted average price of the aggregated shares purchased by the Independent Agent during the purchase period plus a transaction fee which is not expected to exceed $.09 per share. Purchases may begin before the Investment Date and should be completed no more than ten days after the Investment Date, although the purchase period could be longer. The length of the purchase period is affected by the amount of funds to be invested, the availability of shares in the open market and market conditions. In regard to purchases made by the Independent Agent, neither the Company nor any participant will have any authority or power to direct the time or price at which shares may be purchased; the markets on which the shares are to be purchased (including any securities exchange, the over-the-counter market or negotiated transactions); or the selection of the broker or dealer (other than any Independent Agent) through whom purchases may be made. The Independent Agent will combine the funds of all participants for the purpose of executing purchase transactions.

When shares to be purchased are satisfied by newly issued shares, the price will be the average of the high and low prices of the Company's common stock, as reported in The Wall Street Journal's report of New York Stock Exchange Composite Transactions, for the Investment Date (or the next preceding day on which the Company's common stock is traded on the New York Stock Exchange, if it is not traded on the Investment Date), plus a transaction fee which is not expected to exceed $.09 per share.

The primary consideration in determining the source of shares of common stock to be used for purchases under the Plan is expected to be the Company's need to increase equity capital. If the Company does not need to raise funds externally or if the need for funds is satisfied using sources other than the issuance of new shares through the Plan, shares of common stock purchased for participants under the Plan will be purchased in the open market. As of the date of this Prospectus, shares of common stock purchased for participants under the Plan are being purchased in the open market by an Independent Agent.

If shares cannot be purchased with respect to an Investment Date, or if such purchase is deemed to be otherwise inadvisable by the Company or the Independent Agent, the dividends and cash

7

investments which otherwise would have been invested will be paid or returned, as the case may be, to the participants without interest.

14. Q. How many shares of common stock will be purchased?

A. The number of shares (including any fraction of a share rounded to three decimal places) of common stock purchased for you will be determined by dividing the total amount of cash dividends and/or cash investments to be invested for you on such Investment Date by the purchase price.

All shares purchased under the Plan are held by the Company and credited to your Plan account until such time as you request the withdrawal of shares from your Plan account.

15. Q. Do I incur any fees for shares purchased under the Plan?

A. Yes. There is a transaction fee for each share purchased to cover brokerage commissions and administrative costs of the Plan. This transaction fee is not expected to exceed $.09 per share.

SAFEKEEPING OPTION FOR COMMON STOCK CERTIFICATES

16. Q. What is the purpose and advantages of the safekeeping option?

A. The purpose of the Plan's safekeeping option is to enable you to deposit any FirstEnergy common stock certificates into the Plan for safekeeping. The shares are held by the Company and credited to your Plan account, and the shares are shown on dividend checks and/or Plan account statements and otherwise treated in the same manner as shares purchased through the Plan. The Company does not offer safekeeping for preferred stock certificates.

Benefits of the Plan's safekeeping option include: you will not have to worry or bear the cost of protecting stock certificates or replacing certificates due to loss, theft or destruction; you can request that a certificate for whole shares be issued at no cost to you at any time; and because shares held in safekeeping are treated in the same manner as shares purchased through the Plan, you may sell them through the Plan in a convenient manner.

17. Q. How do I use the safekeeping option?

A. At the time of Plan enrollment, you may take advantage of the safekeeping option by sending your certificate(s), unsigned, to FirstEnergy Investor Services with a Plan Enrollment Form. Or, at any time after enrollment, you may send your certificate(s), unsigned, with a signed letter of instruction requesting that the Company hold the shares in safekeeping and stating whether the dividends for shares being sent are to be reinvested or paid in cash. Registered mail is suggested when mailing certificates.

SALES, CERTIFICATE WITHDRAWALS AND CLOSING PLAN ACCOUNTS

18. Q. How do I receive a certificate for or sell a portion of my Plan shares?

A. To receive a certificate for or to sell a portion of the shares credited to your Plan account, you must notify the Company of the number of whole shares to be issued in certificate form or to be sold.

8

19. Q. How do I close my Plan account?

A. To close a Plan account, you must notify the Company and provide instructions as to whether a certificate is to be issued, the shares are to be sold, or both. If both, the number of whole shares for which a certificate is to be issued must be specified so that the remainder of the shares can be sold. When requested to issue a certificate only, or if no instructions are provided, the Company will issue a certificate for all whole shares credited to the account and a check for the value of any fraction of a share. The check for the fraction will be based on the closing sale price of the Company's common stock, as reported in The Wall Street Journal's report of New York Stock Exchange Composite Transactions, for the trading day immediately preceding the day the request is processed by the Company.

20. Q. How long will it take to withdraw certificates or close my Plan account?

A. It normally takes three business days from the time a request is received by the Company until an account is closed or a certificate is issued. However, if we receive your request to close your Plan account between a dividend record date and the date that the additional shares purchased with your reinvested dividend are credited to your account, your request may not be processed until the additional shares are credited to your Plan account (approximately two weeks after the dividend payment date). The additional shares purchased will be added to your account, and all shares will be issued or sold as soon as possible thereafter, depending on your instructions. Upon request, however, the Company can issue a certificate for or sell all whole shares currently in your Plan account, and then close your account by issuing another certificate for or selling the additional shares purchased after the shares are credited to your Plan account.

The Plan does not provide for the automatic issuance of certificates after a purchase, and certificates for fractions of shares will not be issued under any circumstances. Certificates representing Plan shares will be issued in the name under which your account is maintained. If you desire to transfer Plan shares to another registration, you should contact the Company for transfer instructions.

21. Q. How often are shares sold and at what price?

A. Participants' requests to sell Plan shares will be aggregated by the Company and sold at least once a week. (See Question 20 for information on requests to sell all shares in and close a Plan account after a dividend record date). The Company will place a market order with the Independent Agent or broker designated by the Company, who will sell the shares as soon as practicable. Neither the Company nor any participant will have any authority or power to direct the time or price at which shares may be sold.

The price of the shares sold will be the weighted average price of the aggregated shares sold by the Independent Agent or designated broker less a transaction fee which is not expected to exceed $.09 per share. A check for sale of the shares, less the transaction fee, will generally be mailed to the participant three business days after the shares are sold.

22. Q. Will I incur any fees for shares sold under the Plan?

A. Yes. There is a transaction fee for each share sold to cover brokerage commissions and administrative costs of the Plan. This transaction fee is not expected to exceed $.09 per share.

REPORTS TO PARTICIPANTS

23. Q. What reports will I receive as a Plan participant?

A. If you reinvest some or all of your dividends, you will receive a Plan statement about three weeks after each dividend payment date. You will also receive a Plan statement about two weeks after any Investment Date that you invest cash.

If you receive a dividend check for some or all of your dividends, you will receive account information on the stub attached to the check.

In addition to periodic account statements, a FirstEnergy Plan account history report is available at any time upon request to the Company. This report is a summary of all Plan purchases and withdrawals and provides a concise and thorough record for you.

You will receive copies of the same communications sent to other registered shareholders of common stock, including the Company's annual report, interim reports, notice of annual meeting and proxy statement, and income tax information.

TAX CONSEQUENCES

24. Q. What are the tax consequences of participation in the Plan?

A. You will have the same federal income tax obligations with respect to your dividends as shareholders who are not Plan participants. This means that dividends reinvested under the Plan are taxable as ordinary income even though you did not actually receive them in cash.

The selling of shares, including any fractional share, may give rise to a capital gain or loss for federal income tax purposes. Any such gain or loss will be determined by the difference between your net proceeds from the sale and your tax basis in the shares sold.

The original tax basis of shares acquired through the Plan is equal to their purchase price per share, including brokerage commission and other fees. See Question 13 for information regarding the purchase price of shares acquired through the Plan.

Any capital gain or loss will be long-term or short-term according to your holding period and current tax laws. The holding period for the shares acquired under the Plan commences the day after the applicable Investment Date.

The above tax information is only a general discussion of certain tax aspects of an investment in the Plan. You should consult your personal tax adviser as to all of the tax consequences of participating in the Plan, including the application of current and proposed federal, state, local, foreign and other tax laws.

OTHER INFORMATION

25. Q. What happens if the Company issues a stock dividend or declares a stock split?

A. Any shares of common stock distributed by the Company as a stock dividend on shares credited to your Plan account, or as a split of these shares, will be credited to your Plan account. Stock

10

dividends or split shares distributed on any shares held by you in certificate form will be mailed directly to you in the same manner as to shareholders who are not participating in the Plan.

26. Q. If the Company has a rights offering, how will the rights on Plan shares be handled?

A. Rights on shares held by you in certificate form and on any shares, both whole and fractional, credited to your Plan account will be mailed directly to you in the same manner as to shareholders not participating in the Plan.

27. Q. How will shares I hold in the Plan be voted at meetings of shareholders?

A. You will receive a proxy card which will enable you to vote both shares credited to your Plan account and shares held by you in certificate form.

28. Q. Can shares credited to my Plan account be pledged?

A. No. Shares credited to your Plan account may not be pledged. If you wish to pledge such shares you must request the issuance of a stock certificate for such shares.

29. Q. Who bears the risk of market price fluctuations affecting the value of Plan shares?

A. Each individual participant in the Plan bears the risk of market price changes affecting the value of the stock. The Company cannot assure you of a profit or protect you against a loss on any shares you hold, purchase or sell under the Plan.

30. Q. Can the Company terminate my participation in the Plan?

A. If you do not have at least one whole share of common stock credited to your Plan account, your participation in the Plan may be terminated by the Company upon written notice to you. Additionally, the Company may terminate your participation in the Plan after written notice mailed in advance to you. If your participation has been terminated, you will receive (1) a certificate for all of the whole shares of common stock credited to your account, (2) any uninvested dividend or cash investment credited to your account and (3) a check for the cash value of any fraction of a share of common stock credited to your account. Such fraction of a share will be valued at the average of the high and low prices of the Company's common stock as reported in The Wall Street Journal's report of New York Stock Exchange Composite Transactions for the trading day preceding the date of termination.

31. Q. May the Plan be changed, suspended or discontinued?

A. The Company reserves the right, for any reason, to modify, suspend or terminate any provision of the Plan, or the Plan as a whole, at any time. All participants will receive notice of any such modification, suspension or termination. Typically, notice of a modification will be provided prior to the effectiveness of the modification and notice of suspension or termination will be given after the fact, but this may not always be the case. If the Plan is suspended, the Company may similarly, for any reason, reinstate the Plan at any time. Again, notice will be given to participants of the reinstatement and such notice may be given before or after the fact.

11

Upon any termination of the Plan by the Company, you will receive (1) a certificate for all of the whole shares of common stock credited to your account, (2) any uninvested dividend or cash investment credited to your account and (3) a check for the cash value for any fraction of a share of common stock credited to your account. Such fraction of a share will be valued at the average of the high and low prices of the Company's common stock as reported in The Wall Street Journal's report of New York Stock Exchange Composite Transactions for the trading day preceding the date of termination.

USE OF PROCEEDS

The proceeds from the sale to the Plan of any newly issued stock will be used to meet working capital and capital expenditure requirements of the Company's subsidiaries and for other corporate purposes.

DESCRIPTION OF COMMON STOCK

Certain provisions of the Company's Articles of Incorporation and Code of Regulations are summarized or referred to below. The summaries are merely an outline, do not purport to be complete, do not relate to or give effect to the provisions of statutory or common law, and are qualified in their entirety by express reference to such Articles of Incorporation and Code of Regulations.

The Company is authorized by its Articles of Incorporation to issue 300,000,000 shares of common stock, par value $.10 per share, of which approximately 200,000,000 shares were issued and outstanding as of November 13, 1997. The Company is also authorized by its Articles of Incorporation to issue 5,000,000 shares of preferred stock, par value $100 per share, of which none were issued and outstanding as of November 13, 1997. The common stock currently outstanding is, and the common stock offered pursuant to this Prospectus will be, fully paid and non-assessable.

DIVIDEND RIGHTS

Subject only to the prior rights and preferences of any issued and outstanding shares of the Company's preferred stock, the holders of the common stock shall be entitled to receive dividends thereon when, as and if declared by the Board of Directors of the Company out of funds of the Company legally available therefor. There can be no assurance that funds will be legally available to pay dividends at any given time or that, if funds are available, the Board of Directors will declare a dividend.

LIQUIDATION RIGHTS

In the event of any dissolution or liquidation of the Company, the holders of common stock shall be entitled to receive, pro rata, after the prior rights of the holders of any issued and outstanding shares of the Company's preferred stock have been satisfied, all of the assets of the Company that remain available for distribution after payment in full of all liabilities of the Company.

12

VOTING RIGHTS

The holders of common stock of the Company are entitled to one vote on each matter submitted for their vote at any meeting of the shareholders of the Company for each share of the Company's common stock held of record as of the record date for such meeting. Under the Company's Articles of Incorporation, the voting rights, if any, of the Company's preferred stock may differ from the voting rights of the Company's common stock. The holders of common stock are not entitled to cumulate their votes for the election of directors. The Company's Articles of Incorporation provide that the Board of Directors be divided into three classes with the term of office of the respective classes to expire in successive years.

In order to amend or repeal, or adopt any provision inconsistent with, the provisions of the Company's Articles of Incorporation dealing with (a) the right of the Board of Directors to establish the terms of unissued shares or to authorize the acquisition by the Company of its outstanding shares; (b) the absence of cumulative voting and preemptive rights; or (c) the requirement that 80% of the voting power of the Company's outstanding shares must approve the foregoing, 80% of the voting power of the Company's outstanding shares must approve. In addition, the approval of 80% of the voting power of the Company's outstanding shares must be obtained to amend or repeal the provisions of the Company's Code of Regulations dealing with (a) the time and place of shareholders' meetings, the manner in which special meetings of shareholders are called or the way business is conducted at such meetings; (b) the number, election and terms of directors, the manner of filling vacancies on the Board of Directors, the removal of directors or the manner in which directors are nominated; or (c) the indemnification of officers or directors. Amendment of the provision of the Code of Regulations that requires the approval of 80% of the voting power of the Company's outstanding shares in the instances enumerated above requires the same level of approval.

Adoption of amendments to the Company's Articles of Incorporation (other than those requiring 80% approval as specified above), adoption of a plan of merger, consolidation or reorganization, authorization of a sale or other disposition of all or substantially all of the assets of the Company not made in the usual and regular course of its business or adoption of a resolution of dissolution, and any other matter which would otherwise require a two-thirds approving vote, require the approval of two-thirds of the voting power of the Company's outstanding shares, unless the Company's Board of Directors provides otherwise, in which case, these matters will require the approval of a majority of the voting power of the Company's outstanding shares and the approval of a majority of the voting power of any shares entitled to vote as a class.

NO PREEMPTIVE OR CONVERSION RIGHTS

Holders of common stock have no preemptive or conversion rights and are not subject to further calls or assessments by the Company. There are no redemption or sinking fund provisions applicable to the common stock.

LISTING

The outstanding common stock of the Company is traded on the New York Stock Exchange.

13

TRANSFER AGENTS AND REGISTRARS

The Transfer Agent and Registrar for the common stock of the Company is FirstEnergy Securities Transfer Company, a wholly owned subsidiary of the Company.

The steps to be taken which are referred to in the next preceding paragraph consist of the following:

(1) Appropriate definitive action by the Board of Directors of the Company or an authorized committee thereof with respect to the issuance of the Shares.
