immediately preceding the corresponding Interest Payment Date; provided, however, that interest payable at Maturity will be paid to the Person to whom principal is paid. Any such interest not so punctually paid or duly provided for
will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture referred to on the reverse

 Payment of the principal of (and premium, if any) and interest on this Security will be made at the office or agency of the
Company maintained for that purpose in The City of New York, the State of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided,
however, that, at the option of the Company, interest on this Security may be paid by check mailed to the

 [FORM OF REVERSE OF NOTE] 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued under
an Indenture, dated as of November 15, 2001 (herein, together with any amendments thereto, called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New
York Mellon Trust Company, N.A., as successor trustee to Bank One Trust Company, N.A., (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the
Indenture, including the Board Resolutions and Officer’s Certificate filed with the Trustee on February 20, 2020 creating the series designated on the face hereof, for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. 

Securities of this series shall be redeemable at the option of the Company, in whole or in part from time to time, upon notice mailed to each
registered owner, at his last address appearing on the Security Register, (i) prior to the date that is one month prior to the Maturity Date, at a redemption price equal to the greater of (1) 100% of the principal amount of the Securities of
this series to be redeemed then outstanding; or (2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and interest on the Securities of this series to be redeemed
(not including any portion of the payments of interest accrued to the date of redemption) that would be due if the Securities matured on the date that is one month prior to the Maturity Date, discounted to the redemption date on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 12.5 basis points, and (ii) on or after the date that is one month
prior to the Maturity Date at a redemption price equal to 100% of the principal amount of the Securities of this series to be redeemed then outstanding, in each case plus accrued and unpaid interest to, but not including, the date of redemption on
the Securities of this series to be redeemed. 
 “Adjusted Treasury Rate” means, with respect to any redemption date: 

 

	 	•	 	 the yield, under the heading which represents the average for the immediately preceding week, appearing in the
most recently published statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States
Treasury securities adjusted to constant maturity, for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely
corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from these yields on a straight line basis, rounding to the nearest month); or 



 

	 	•	 	 if the release (or any successor release) is not published during the week preceding the calculation date or does
not contain these yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal
to the Comparable Treasury Price for the redemption date. The Adjusted Treasury Rate will be calculated on the third Business Day preceding the redemption date. 



  
 A-5 













 “Comparable Treasury Issue” means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed (assuming, for this purposes, that the Securities mature on the date that is one month prior to the
Maturity Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such securities
(“Remaining Life”). 
 “Comparable Treasury Price” means (1) the average of three Reference Treasury
Dealer Quotations for the redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than three Reference Treasury Dealer Quotations, the average of
all such quotations. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the
Company. 
 “Reference Treasury Dealer” means: 
  

	 	•	 	 each of Barclays Capital Inc., BofA Securities, Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC
and Morgan Stanley & Co. LLC and their respective successors; provided, however, that if any of the foregoing cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the
Company will substitute another Primary Treasury Dealer; and 


  

	 	•	 	 any two other Primary Treasury Dealers selected by the Company. 



“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at
5:00 p.m., New York City time, on the third Business Day preceding the redemption date. 
 The Company will mail a notice of redemption at
least 30 days but not more than 60 days before the applicable redemption date to each holder of the Securities of this series to be redeemed. If the Company elects to partially redeem the Securities of this series, the Securities of this series to
be redeemed will be selected in accordance with the applicable policies and procedures of the Depositary. The redemption price determined by the Independent Investment Banker, absent manifest error, shall be binding and conclusive upon the Holders
of the Securities of this series, the Company and the Trustee. 
 If at the time notice of redemption is given, the redemption monies are
not on deposit with the Trustee, then the redemption shall be subject to their receipt on or before the redemption date and such notice shall be of no effect unless such monies are received. 

  
 A-6 













 Upon payment of the redemption price, interest will cease to accrue on and after the
applicable redemption date on the Securities of this series or portions thereof called for redemption. The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions
set forth in the Indenture. 
 If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal
of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The
Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture
at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected. The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of
Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000
in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor and of authorized
denominations, as requested by the Holder surrendering the same. 

  
 A-7 













 No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
 The
Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the absolute owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary. 
 All terms used in this Security which are defined in the
Indenture shall have the meanings assigned to them in the Indenture. 

  
 A-8 













 LEGEND

holders hereof as then certified to the Trustee by The Depository Trust Company (55 Water Street, New York, New York) or its successor (the “Depositary”), this Security may not be transferred except as a whole by the Depositary to a
nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

This Security may be exchanged for certificated Securities registered in the names of the various beneficial owners hereof if (a) the
Depositary is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by the Company within 90 days, or (b) the Company elects to issue certificated Securities to beneficial owners. Any such
exchange shall be made upon receipt by the Trustee of a Company Order therefor and certificated Securities of this series shall be registered in such names and in such denominations as shall be certified to the Company and the Trustee by the
Depositary.

be redeemed will be selected in accordance with the applicable policies and procedures of the Depositary. The redemption price determined by the Independent Investment Banker, absent manifest error, shall be binding and conclusive upon the Holders
of the Securities of this series, the Company and the Trustee. 
 If at the time notice of redemption is given, the redemption monies are
not on deposit with the Trustee, then the redemption shall be subject to their receipt on or before the redemption date and such notice shall be of no effect unless such monies are received.

Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture
at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected. The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of
Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000
in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor and of authorized
denominations, as requested by the Holder surrendering the same.

FIRSTENERGY CORP. 
 3.400% NOTES,
SERIES C, DUE 2050 
 FirstEnergy Corp., a corporation duly organized and existing under the laws of the State of Ohio (herein referred to

the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not

 [FORM OF REVERSE OF NOTE] 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued under
an Indenture, dated as of November 15, 2001 (herein, together with any amendments thereto, called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New
York Mellon Trust Company, N.A., as successor trustee to Bank One Trust Company, N.A., (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the
Indenture, including the Board Resolutions and Officer’s Certificate filed with the Trustee on February 20, 2020 creating the series designated on the face hereof, for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. 

Securities of this series shall be redeemable at the option of the Company, in whole or in part from time to time, upon notice mailed to each
registered owner, at his last address appearing on the Security Register, (i) prior to the date that is six months prior to the Maturity Date, at a redemption price equal to the greater of (1) 100% of the principal amount of the Securities of
this series to be redeemed then outstanding; or (2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and interest on the Securities of this series to be redeemed
(not including any portion of the payments of interest accrued to the date of redemption) that would be due if the Securities matured on the date that is six months prior to the Maturity Date, discounted to the redemption date on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 25 basis points, and (ii) on or after the date that is six months
prior to the Maturity Date at a redemption price equal to 100% of the principal amount of the Securities of this series to be redeemed then outstanding, in each case plus accrued and unpaid interest to, but not including, the date of redemption on
the Securities of this series to be redeemed. 
 “Adjusted Treasury Rate” means, with respect to any redemption date: 

 

	 	•	 	 the yield, under the heading which represents the average for the immediately preceding week, appearing in the
most recently published statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States
Treasury securities adjusted to constant maturity, for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely
corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from these yields on a straight line basis, rounding to the nearest month); or 



 

	 	•	 	 if the release (or any successor release) is not published during the week preceding the calculation date or does
not contain these yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal
to the Comparable Treasury Price for the redemption date. The Adjusted Treasury Rate will be calculated on the third Business Day preceding the redemption date. 



  
 C-5 













 “Comparable Treasury Issue” means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed (assuming, for this purposes, that the Securities mature on the date that is six months prior to the
Maturity Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such securities
(“Remaining Life”). 
 “Comparable Treasury Price” means (1) the average of three Reference
Treasury Dealer Quotations for the redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than three Reference Treasury Dealer Quotations, the
average of all such quotations. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by
the Company. 
 “Reference Treasury Dealer” means: 

 

	 	•	 	 each of Barclays Capital Inc., BofA Securities, Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC
and Morgan Stanley & Co. LLC and their respective successors; provided, however, that if any of the foregoing cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the
Company will substitute another Primary Treasury Dealer; and 


  

	 	•	 	 any two other Primary Treasury Dealers selected by the Company. 



“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at
5:00 p.m., New York City time, on the third Business Day preceding the redemption date. 
 The Company will mail a notice of redemption at
least 30 days but not more than 60 days before the applicable redemption date to each holder of the Securities of this series to be redeemed. If the Company elects to partially redeem the Securities of this series, the Securities of this series to
be redeemed will be selected in accordance with the applicable policies and procedures of the Depositary. The redemption price determined by the Independent Investment Banker, absent manifest error, shall be binding and conclusive upon the Holders
of the Securities of this series, the Company and the Trustee. 
 If at the time notice of redemption is given, the redemption monies are
not on deposit with the Trustee, then the redemption shall be subject to their receipt on or before the redemption date and such notice shall be of no effect unless such monies are received. 

  
 C-6 













 Upon payment of the redemption price, interest will cease to accrue on and after the
applicable redemption date on the Securities of this series or portions thereof called for redemption. The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions
set forth in the Indenture. 
 If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal
of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The
Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture
at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected. The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of
Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000
in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor and of authorized
denominations, as requested by the Holder surrendering the same. 

  
 C-7 













 No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
 The
Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the absolute owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

Indenture shall have the meanings assigned to them in the Indenture.
