outstanding under the OWDA 2006-A Reimbursement Agreement (other than Tender
Advances or reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the OWDA 2006-A Reimbursement
Agreement).  The obligation of the Company to make any payment with
respect to the principal of the bonds of Collateral Series F shall be
credited in full if, at the time that any such payment of principal shall be
due, there shall have been paid by or for the account of the Company an
equivalent amount of Obligations constituting demand loans pursuant to Section
2.04 of the OWDA 2006-A Reimbursement Agreement.  No payment of
principal of such Tender Advances or demand loans under the OWDA 2006-A
Reimbursement Agreement or under the bonds of Collateral Series F shall
reduce the stated principal amount of the bonds of Collateral Series F unless,
and only to the extent that, the OWDA 2006-A Reimbursement Agreement shall be
terminated concurrently therewith in accordance with the provisions of Section
2.02(c) of the OWDA 2006-A Reimbursement Agreement.

       

      (m)           The
Trustee may conclusively presume that the obligation of the Company to pay the
principal of, and interest on, the bonds of Collateral Series F, as the
same shall become due and payable, has been credited in accordance with this
Section 2.04 unless and until it shall have received a written notice (including
a telecopy or other form of written communication) from an authorized
representative of the Administrative Agent stating that payment of Obligations
due under the OWDA 2006-A Reimbursement Agreement has become due and payable and
has not been fully paid and specifying the amount of funds required to make such
payment.

       

      (n)           The
Company shall receive a credit against its obligation to make any payment of
interest on the bonds of Collateral Series G, whether
on an Interest Payment Date, at maturity, upon redemption, upon acceleration or
otherwise, in an amount equal to the amount, if any, paid by or for the account
of the Company in respect of any corresponding payment of the Obligations
outstanding under the BCIDA 2006-A Reimbursement Agreement (other than Tender
Advances or reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the BCIDA 2006-A Reimbursement
Agreement).  The obligation of the Company to make any payment with
respect to the principal of the bonds of

      Collateral Series G shall be

due, there shall have been paid by or for the account of the Company an
equivalent amount of Obligations constituting demand loans pursuant to Section
2.04 of the BCIDA 2006-A Reimbursement Agreement.  No payment of
principal of such Tender Advances or demand loans under the BCIDA 2006-A
Reimbursement Agreement or under the bonds of Collateral Series G shall
reduce the stated principal amount of the bonds of Collateral Series G unless,
and only to the extent that, the BCIDA 2006-A Reimbursement Agreement shall be
terminated concurrently therewith in accordance with the provisions of Section
2.02(c) of the BCIDA 2006-A Reimbursement Agreement.

       

      (o)           The
Trustee may conclusively presume that the obligation of the Company to pay the
principal of, and interest on, the bonds of Collateral Series G, as the
same shall become due and payable, has been credited in accordance with this
Section 2.04 unless and until it shall have received a written notice (including
a telecopy or other form of written communication) from an authorized
representative of the Administrative Agent stating that payment of Obligations
due under the BCIDA 2006-A Reimbursement Agreement has become due and payable
and has not been fully paid and specifying the amount of funds required to make
such payment.

N.A., as trustee (the “Revenue Bond

between the Ohio Water Development Authority and the Revenue Bond Trustee,
securing $107,500,000 of State of Ohio Pollution Control Revenue Refunding
Bonds, Series 2009-A (FirstEnergy Nuclear Generation Corp. Project) issued for
the benefit of the Company (the “Revenue
Bonds”) (such Trust Indenture, as amended from time to time, hereinafter
the “Revenue Bond
Indenture”), or registered assigns, on June 1, 2033, the principal sum of
[_____________________] Dollars, and to pay interest on the unpaid principal
amount from the Initial Interest Accrual Date (as hereinafter defined) at the
Revenue Bond Interest Rate (as hereinafter defined) per annum payable
semi-annually on June 1 and December 1 in each year commencing on the June 1 or
December 1 immediately succeeding the Initial Interest Accrual Date (each such
date herein referred to as an “Interest Payment
Date”) on and until maturity, or, in the case of any Bonds of this series
duly called for redemption, on and until the redemption date, or in the case of
any default by the Company in the payment of the principal due on any Bonds of
this series, until the Company’s obligation with respect to the payment of such
principal shall be discharged as provided in the Indenture (as hereinafter
defined).  The
interest on each Bond of this series so payable on any Interest Payment Date
shall, subject to the exceptions provided in Section 3.07 of the Indenture, be
paid to the person in whose name such Bond is registered on the date of such
payment.  The principal of, and the interest on, this Bond shall be
payable at the office or agency of the Company in the City of Cleveland, State
of Ohio in any coin or currency of the United States of America which at the
time of payment is legal tender for the payment of public and private

      This Bond is one of
an issue of Bonds of the Company known as its First Mortgage Bonds, issued and
to be issued in one or more series under and secured by an Open-End Mortgage,
General Mortgage Indenture and Deed of Trust, dated as of June 1, 2009, duly
executed by the Company to The Bank of New York Mellon Trust Company, N.A., a
national banking association organized and existing under the laws of the United
States of America, as Trustee (the “Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the First Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental
Indenture”), to
which Open-End Mortgage, General Mortgage Indenture and Deed of Trust and all
indentures supplemental thereto (collectively referred to as the “Indenture”)
reference is hereby made for a description of the property mortgaged and
pledged, the nature and extent of the security, the terms and conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, such Bonds may be in various principal sums, are
issuable in series, may mature at different times, may bear interest at
different rates and may otherwise vary as therein provided; and this Bond is one
Bond of a series entitled “First Mortgage Bonds, Guarantee Series A of 2009 due
2033,” created by the Supplemental Indenture, as provided for in the Indenture,
and authorized for issuance in an aggregate principal amount of up to
$107,500,000.

       

      If and when the
principal of any Revenue Bonds is paid, then there is deemed to be paid an equal
principal amount of the Bonds of this series then outstanding; provided,
however, that such payment of the Bonds of this series is deemed to be made only
when and to the extent that notice of such payment of such Revenue Bonds is
given by the Company to the Trustee.

       

      The Bonds of this
series shall be redeemed by the Company in whole at any time prior to maturity
at a redemption price of 100% of the principal amount thereof plus accrued and
unpaid interest to the date of redemption following receipt by the Trustee of
written demand for redemption (a “Redemption
Demand”) from an authorized representative of the Revenue Bond Trustee
under the Revenue Bond Indenture stating that the principal amount of all the
Revenue Bonds then outstanding under the Revenue Bond Indenture has been
declared due and payable pursuant to the provisions of Section 11.02 of the
Revenue Bond Indenture, specifying the date of the accelerated maturity of such
Revenue Bonds and the date or dates from which interest on the Revenue Bonds has
then accrued and is unpaid (specifying the rate or rates of such accrual and the
principal amount of the particular Revenue Bonds to which such rates apply),
stating such declaration of maturity has not been annulled and demanding payment
of the principal amount of the Bonds of this series plus accrued interest
thereon to the date fixed for such redemption. The date fixed for such
redemption shall be set forth in the aforesaid Redemption Demand and shall not
be earlier than the date specified in such Redemption Demand as the date of
accelerated maturity of the Revenue Bonds then outstanding under the Revenue
Bond Indenture and not later than forty-five days after the Trustee’s receipt of
such Redemption Demand unless such forty-fifth day is earlier than such date of
accelerated maturity.  The Revenue Bond Trustee as the sole holder of
the Bonds of this series, and any successor thereto, hereby irrevocably waives
any requirement of notice of such redemption under Section 5.04 of the
Indenture.  Upon receipt of the aforesaid Redemption Demand, the
earliest date from which unpaid interest on the Revenue Bonds has then accrued
(as specified by the Revenue Bond Trustee in the Redemption Demand) shall become
the initial interest accrual date (the “Initial Interest
Accrual Date”) with respect to the Bonds of this series; provided,
however, on any

      demand for payment
of the principal amount thereof at maturity as a result of the principal of the
Revenue Bonds becoming due and payable on the maturity date of the Bonds of this
series, the earliest date from which unpaid interest on the Revenue Bonds has
then accrued shall become the Initial Interest Accrual Date with respect to the
Bonds of this series, such date, together with each other different date from
which unpaid interest on the Revenue Bonds has then accrued, to be as stated in
a written notice from the Revenue Bond Trustee to the Trustee, which notice
shall also specify the rate or rates of such accrual and the principal amount of
the particular Revenue Bonds to which such rate or rates apply.  Such
redemption shall become null and void for all purposes under the Indenture
(including the fixing of the Initial Interest Accrual Date with respect to the
Bonds of this series) upon receipt by the Trustee of written notice from the
Revenue Bond Trustee of the annulment of the acceleration of the maturity of the
Revenue Bonds then outstanding under the Revenue Bond Indenture and of the
rescission of the aforesaid Redemption Demand prior to the redemption date
specified in the Redemption Demand, and thereupon no redemption of the Bonds of
this series and no payment in respect thereof as specified in the Redemption
Demand, shall be effected or required.  But no such rescission shall
extend to any subsequent Redemption Demand from the Revenue Bond Trustee or
impair any right consequent on any such subsequent Redemption
Demand.

       

      The “Revenue Bond
Interest Rate” shall be the same rate of interest per annum as is borne
by the Revenue Bonds; provided, however, that if there are different rates of
interest borne by the Revenue Bonds, or if interest is required to be paid on
the Revenue Bonds more frequently than on each June 1 or December 1, the Revenue
Bond Interest Rate shall be the rate that results in the total amount of
interest payable on an Interest Payment Date, a redemption date or at maturity,
as the case may be, or at any other time interest on this Bond is due and
payable, to be equal to the total amount of unpaid interest that has accrued on
all then outstanding Revenue Bonds.

       

      The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

      

      From and after the
Release Date (as defined in the Revenue Bond Indenture), the Bonds of this
series shall be deemed fully paid, satisfied and discharged and the obligation
of the Company thereunder shall be terminated.  On the Release Date or
promptly following, the Bonds of this series shall be surrendered to and
cancelled by the Trustee.

      

      No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

      This Bond is
nontransferable except to (i) effect transfer to any successor to the Revenue
Bond Trustee under the Revenue Bond Indenture, (ii) in connection with the
exercise of the rights and remedies of the holder hereof consequent upon an
“Event of Default” as defined in the Indenture or (iii) as may be necessary to
comply with a final order of a court of competent jurisdiction in connection
with any bankruptcy or reorganization proceeding of the Company.  But
this Bond is exchangeable by the registered holder hereof, in person or by
attorney duly authorized, at the Corporate Trust Office of the Trustee, any such
permitted transfer or exchange to be made in the manner and upon the conditions
prescribed in the Indenture, upon the surrender and cancellation of this Bond
and the payment of any applicable taxes and fees required by law, and upon any
such transfer or exchange a new registered Bond or Bonds of the same series and
tenor, will be issued to the authorized transferee, or the registered holder, as
the case may be. The Company and the Trustee may deem and treat the person in
whose name this Bond is registered as the absolute owner for the purpose of receiving
payment of or on account of the principal and interest due hereon and for all
other purposes.

      

      This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

      

      IN WITNESS WHEREOF,
the Company has caused this Bond to be executed in its name by the manual or
facsimile signature of an Authorized Executive Officer and attested by the
manual or facsimile signature of another Authorized Executive
Officer.

      This Bond is one of
an issue of Bonds of the Company known as its First Mortgage Bonds, issued and
to be issued in one or more series under and secured by an Open-End Mortgage,
General Mortgage Indenture and Deed of Trust, dated as of June 1, 2009, duly
executed by the Company to The Bank of New York Mellon Trust Company, N.A., a
national banking association organized and existing under the laws of the United
States of America, as Trustee (the “Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the First Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental
Indenture”), to
which Open-End Mortgage, General Mortgage Indenture and Deed of Trust and all
indentures supplemental thereto (collectively referred to as the “Indenture”)
reference is hereby made for a description of the property mortgaged and
pledged, the nature and extent of the security, the terms and conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, such Bonds may be in various principal sums, are
issuable in series, may mature at different times, may bear interest at
different rates and may otherwise vary as therein provided; and this Bond is one
Bond of a series entitled “First Mortgage Bonds, Guarantee Series B of 2009 due
2011,” created by the Supplemental Indenture, as provided for in the Indenture,
and authorized for issuance in an aggregate principal amount of up to
$500,000,000.

       

      Upon receipt of a
Demand Notice (as defined in the Guaranty Agreement) by the Company and the
Trustee from an authorized representative of the holder hereof at any time prior
to maturity, the Bonds of this series shall be redeemed by the Company in whole
on the third Business Day following receipt of such notice at a redemption price
equal to the lesser of (a) the Demand Amount specified in such Demand Notice and
(b) 100% of the aggregate maximum principal amount of Bonds of this series then
outstanding.  Any such redemption shall become null and void for all
purposes under the Indenture upon receipt by the Company and the Trustee of
written notice from an authorized representative of the holder hereof of the
rescission of the aforesaid Demand Notice prior to the redemption date, and
thereupon no redemption of the Bonds of this series and no payment in respect
thereof as specified in the Demand Notice, shall be effected or
required.  But no such rescission shall extend to any subsequent
Demand Notice from an authorized representative of the holder hereof or impair
any right consequent on any such subsequent Demand Notice.

       

      The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.  In such event,
the aggregate amount due and payable in respect of the Bonds of this series
shall be the Default Amount (as defined in the Guaranty Agreement) as of such
date.  Upon notice to the holder hereof of any such declaration or
acceleration, the holder shall provide the Trustee with a calculation of such
Default Amount.

      

      No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect

dated as of December 16, 2005, among the Company, Barclays Bank PLC, acting
through its New York Branch, as Fronting Bank and Administrative Agent and the
Banks parties thereto from time to time (such Reimbursement Agreement, as
amended from time to time, hereinafter the “Reimbursement
Agreement”), or registered assigns, on December 16, 2010, the principal
sum of [_____________________] Dollars or, at any time (if less), such lesser
principal amount as is equal to the sum of (a) the Available Amount of the
Letter of Credit outstanding at such time, plus (b) the aggregate principal
amount of all Tender Advances which are outstanding at such time, plus (c) the
aggregate amount of all other reimbursement obligations of the Company to the
Banks constituting demand loans pursuant to Section 2.04 of the Reimbursement
Agreement which are outstanding at such time, on such date or dates and in such
amounts as set forth in the Reimbursement Agreement for the payment of principal
on such Tender Advances and demand loans, and to pay interest on said principal
amount from the date hereof at such rate or rates per annum on each day as
shall cause the amount of interest payable on the Bonds of this series on an
Interest Payment Date (as hereinafter defined) to equal the amount of
outstanding Obligations (other than Tender Advances or reimbursement obligations
of the Company to the Banks constituting demand loans pursuant to Section 2.04
of the Reimbursement Agreement) payable on such Interest Payment Date; provided,
however,
that such interest rate or rates shall not exceed ten percent (10%) per annum

hereon until the principal hereof shall be paid in full, subject to Section 2.04
of the First Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental
Indenture”),
executed and delivered by the Company to the Trustee (as hereinafter defined),
which provides for certain credits towards payment of principal of, and interest
on, the Bonds of this series.  No payment of principal under such
Tender Advances or demand loans or hereunder shall reduce the stated principal
amount of the Bonds of this series unless, and only to the extent that, the
Reimbursement Agreement shall be terminated concurrently therewith in accordance
with the provisions of Section 2.02(c) of the Reimbursement
Agreement.  Interest shall accrue on the Bonds of this series from the
date of issuance hereof, and the payment thereof shall be credited as provided
in Section 2.04(a) of the Supplemental Indenture unless and until the Trustee
receives the notice contemplated by Section 2.04(b) of the Supplemental
Indenture, whereupon the interest on the Bonds of this series shall become and
remain due and payable until such time as the Trustee receives a further written
notice (including a telecopy or other form of written telecommunication) from an
authorized representative of the Administrative Agent stating that such payments
need not continue.  The interest on each Bond of this series so
payable on any Interest Payment Date shall, subject to the exceptions provided
in Section 3.07 of the Indenture (as hereinafter defined) and to the provisions
of Section 2.04 of the Supplemental Indenture, be paid to the person in whose
name such Bond is registered on the date of such payment.  The
principal of, and the interest on, this Bond shall be payable at the office or
agency of the Company in the City of Cleveland, State of Ohio in any coin or
currency of the United States of America which at the time of payment is legal
tender for the payment of public and private debts.

       

      As used herein,
“Interest
Payment Date” shall mean (i) in the case of Obligations representing
interest payable on Tender Advances or on reimbursement obligations of the
Company to the Banks constituting demand loans pursuant to Section 2.04 of the
Reimbursement Agreement, the date on which any such interest is due under and as
provided in the Reimbursement Agreement, and (ii) in the case of Obligations
other than (x) interest covered by the preceding clause (i) and (y) Tender
Advances or reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement, the
applicable date for the payment of such Obligations under the Reimbursement
Agreement.  As used herein, the terms “Available
Amount,” “Banks,”
“Commitments,”
“Letter of
Credit,” “Obligations,” and “Tender
Advances” shall have the respective meanings set forth in the
Reimbursement Agreement.  The Letter of Credit was issued in favor of
the bond trustee for $8,000,000 aggregate principal amount of State of Ohio
Pollution Control Revenue Refunding Bonds, Series 2005-A (FirstEnergy Nuclear
Generation Corp. Project) issued by the Ohio Air Quality Development
Authority.

       

      This Bond is one of
an issue of Bonds of the Company issued and to be issued in one or more series
under and secured by an Open-End Mortgage, General Mortgage Indenture and Deed
of Trust, dated as of June 1, 2009, duly executed by the Company to The Bank of
New York Mellon Trust Company, N.A., a national banking association organized
and existing under the laws of the United States of America, as Trustee (the
“Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the Supplemental Indenture, to which Open-End Mortgage, General Mortgage
Indenture and Deed of Trust and all indentures supplemental thereto
(collectively referred to as the “Indenture”)
reference is hereby made for a description of the property mortgaged and

      conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, such Bonds may be in various principal sums, are
issuable in series, may mature at different times, may bear interest at
different rates and may otherwise vary as therein provided; and this Bond is one
Bond of a series entitled “First Mortgage Bonds, Collateral Series A of 2009
due 2010,” created by the Supplemental Indenture, as provided for in the
Indenture, and authorized for issuance in an aggregate principal amount of up to
$8,079,000.

       

      Any payment of
Obligations made by or on behalf of the Company in respect of the Reimbursement
Agreement shall be deemed a payment in respect of this Bond, but such payment
shall not reduce the principal amount of this Bond then in effect unless the sum
of (a) the Available Amount of the Letter of Credit outstanding at such time,
plus (b) the aggregate principal amount of all Tender Advances which are then
outstanding under the Reimbursement Agreement, plus (c) the aggregate amount of
all other reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement which are
outstanding at such time, is irrevocably reduced concurrently with such payment;
provided,
however,
if after a drawing under the Letter of Credit, the Letter of Credit shall have
been reinstated in respect of such drawing prior to the Administrative Agent,
Fronting Bank or Banks having received reimbursement for such drawing from the
Company, the reimbursement of such reinstated amount shall not reduce the
principal amount of this Bond.  In the event that all of the Company's
obligations under the Reimbursement Agreement have been discharged and the
Letter of Credit shall have been cancelled and returned to the Fronting Bank,
this Bond shall be deemed paid in full and the Holder shall surrender this Bond
to the Trustee for cancellation.

       

      The Bonds of this
series shall be redeemed promptly, without notice, by the Company in whole at
100% of the principal amount thereof plus accrued interest to the date of
redemption (the “Redemption
Price”) following receipt by the Trustee of written demand for redemption
(a “Redemption
Demand”)  from an authorized representative of the
Administrative Agent under the Reimbursement Agreement stating that (i) all of
the Obligations under the Reimbursement Agreement have become or have been
declared to be immediately due and payable as a result of the occurrence and
continuance of an “Event of Default” under the Reimbursement Agreement and (ii)
that the Administrative Agent has demanded payment thereof from the Company;
provided that the Bonds
of this series shall be redeemed automatically by the Company, without any
notice to any person, in whole at the Redemption Price, if the Obligations under
the Reimbursement Agreement have become immediately due and payable as a result
of the occurrence of an “Event of Default” under the Reimbursement Agreement
with respect to the Company (but not any subsidiary thereof) under Section
6.01(f) of the Reimbursement Agreement.  Such redemption shall be
effected on the fifth Business Day following receipt by the Trustee of the
Redemption Demand, if such Redemption Demand is required, or the occurrence of
an “Event of Default” under the Reimbursement Agreement with respect to the
Company (but not any subsidiary thereof) under Section 6.01(f) of the
Reimbursement Agreement.  Any payment of the Redemption Price made to
the Administrative Agent shall constitute a payment by the Company in respect of
Obligations under the Reimbursement Agreement.  A Redemption Demand
shall be rescinded and shall be null and void for all purposes of the Indenture
upon receipt by the Trustee, no later than the Business Day prior to
the

       date fixed for
redemption, of a written notice from the Administrative Agent withdrawing said
Redemption Demand.

       

       

      The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

       

      No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

       

      This Bond is
nontransferable except to effect transfer to any successor to the Administrative
Agent under the Reimbursement Agreement, but is exchangeable by the registered
holder hereof, in person or by attorney duly authorized, at the Corporate Trust
Office of the Trustee, any such permitted transfer or exchange to be made in the
manner and upon the conditions prescribed in the Indenture, upon the surrender
and cancellation of this Bond and the payment of any applicable taxes and fees
required by law, and upon any such transfer or exchange a new registered Bond or
Bonds of the same series and tenor, will be issued to the authorized transferee,
or the registered holder, as the case may be. The Company and the Trustee may
deem and treat the person in whose name this Bond is registered as the absolute
owner for the purpose of
receiving payment of or on account of the principal and interest due hereon and
for all other purposes.

       

      This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

      

      IN WITNESS WHEREOF,

supplemented, modified or restated, the “Supplemental
Indenture”),
executed and delivered by the Company to the Trustee (as hereinafter defined),
which provides for certain credits towards payment of principal of, and interest
on, the Bonds of this series.  No payment of principal under such
Tender Advances or demand loans or hereunder shall reduce the stated principal
amount of the Bonds of this series unless, and only to the extent that, the
Reimbursement Agreement shall be terminated concurrently therewith in accordance
with the provisions of Section 2.02(c) of the Reimbursement
Agreement.  Interest shall accrue on the Bonds of this series from the
date of issuance hereof, and the payment thereof shall be credited as provided
in Section 2.04(a) of the Supplemental Indenture unless and until the Trustee
receives the notice contemplated by Section 2.04(b) of the Supplemental
Indenture, whereupon the interest on the Bonds of this series shall become and
remain due and payable until such time as the Trustee receives a further written
notice (including a telecopy or other form of written telecommunication) from an
authorized representative of the Administrative Agent stating that such payments
need not continue.  The interest on each Bond of this series so
payable on any Interest Payment Date shall, subject to the exceptions provided
in Section 3.07 of the Indenture (as hereinafter defined) and to the provisions
of Section 2.04 of the Supplemental Indenture, be paid to the person in whose
name such Bond is registered on the date of such payment.  The
principal of, and the interest on, this Bond shall be payable at the office or
agency of the Company in the City of Cleveland, State of Ohio in any coin or
currency of the United States of America which at the time of payment is legal
tender for the payment of public and private debts.

       

      As used herein,
“Interest
Payment Date” shall mean (i) in the case of Obligations representing
interest payable on Tender Advances or on reimbursement obligations of the
Company to the Banks constituting demand loans pursuant to Section 2.04 of the
Reimbursement Agreement, the date on which any such interest is due under and as
provided in the Reimbursement Agreement, and (ii) in the case of Obligations
other than (x) interest covered by the preceding clause (i) and (y) Tender
Advances or reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement, the
applicable date for the payment of such Obligations under the Reimbursement
Agreement.  As used herein, the terms “Available
Amount,” “Banks,”
“Commitments,”
“Letter of
Credit,” “Obligations,” and “Tender
Advances” shall have the respective meanings set forth in the
Reimbursement Agreement.  The Letter of Credit was issued in favor of
the bond trustee for $7,200,000 aggregate principal amount of State of Ohio
Pollution Control Revenue Refunding Bonds, Series 2005-B (FirstEnergy Nuclear
Generation Corp. Project) issued by the Ohio Air Quality Development
Authority.

       

      This Bond is one of
an issue of Bonds of the Company issued and to be issued in one or more series
under and secured by an Open-End Mortgage, General Mortgage Indenture and Deed
of Trust, dated as of June 1, 2009, duly executed by the Company to The Bank of
New York Mellon Trust Company, N.A., a national banking association organized
and existing under the laws of the United States of America, as Trustee (the
“Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the Supplemental Indenture, to which Open-End Mortgage, General Mortgage
Indenture and Deed of Trust and all indentures supplemental thereto
(collectively referred to as the “Indenture”)
reference is hereby made for a description of the property mortgaged and
pledged, the nature and extent of the security, the terms and conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, 

       

       

      
        
          
          

        

        
          
                                                                                Exhibit

      such Bonds may be in
various principal sums, are issuable in series, may mature at different times,
may bear interest at different rates and may otherwise vary as therein provided;
and this Bond is one Bond of a series entitled “First Mortgage Bonds, Collateral
Series B of 2009 due 2010,” created by the Supplemental Indenture, as provided
for in the Indenture, and authorized for issuance in an aggregate principal
amount of up to $7,272,000.

       

      Any payment of
Obligations made by or on behalf of the Company in respect of the Reimbursement
Agreement shall be deemed a payment in respect of this Bond, but such payment
shall not reduce the principal amount of this Bond then in effect unless the sum
of (a) the Available Amount of the Letter of Credit outstanding at such time,
plus (b) the aggregate principal amount of all Tender Advances which are then
outstanding under the Reimbursement Agreement, plus (c) the aggregate amount of
all other reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement which are
outstanding at such time, is irrevocably reduced concurrently with such payment;
provided,
however,
if after a drawing under the Letter of Credit, the Letter of Credit shall have
been reinstated in respect of such drawing prior to the Administrative Agent,
Fronting Bank or Banks having received reimbursement for such drawing from the
Company, the reimbursement of such reinstated amount shall not reduce the
principal amount of this Bond.  In the event that all of the Company's
obligations under the Reimbursement Agreement have been discharged and the
Letter of Credit shall have been cancelled and returned to the Fronting Bank,
this Bond shall be deemed paid in full and the Holder shall surrender this Bond
to the Trustee for cancellation.

       

      The Bonds of this
series shall be redeemed promptly, without notice, by the Company in whole at
100% of the principal amount thereof plus accrued interest to the date of
redemption (the “Redemption
Price”) following receipt by the Trustee of written demand for redemption
(a “Redemption
Demand”)  from an authorized representative of the
Administrative Agent under the Reimbursement Agreement stating that (i) all of
the Obligations under the Reimbursement Agreement have become or have been
declared to be immediately due and payable as a result of the occurrence and
continuance of an “Event of Default” under the Reimbursement Agreement and (ii)
that the Administrative Agent has demanded payment thereof from the Company;
provided that the Bonds
of this series shall be redeemed automatically by the Company, without any
notice to any person, in whole at the Redemption Price, if the Obligations under
the Reimbursement Agreement have become immediately due and payable as a result
of the occurrence of an “Event of Default” under the Reimbursement Agreement
with respect to the Company (but not any subsidiary thereof) under Section
6.01(f) of the Reimbursement Agreement.  Such redemption shall be
effected on the fifth Business Day following receipt by the Trustee of the
Redemption Demand, if such Redemption Demand is required, or the occurrence of
an “Event of Default” under the Reimbursement Agreement with respect to the
Company (but not any subsidiary thereof) under Section 6.01(f) of the
Reimbursement Agreement.  Any payment of the Redemption Price made to
the Administrative Agent shall constitute a payment by the Company in respect of
Obligations under the Reimbursement Agreement.  A Redemption Demand
shall be rescinded and shall be null and void for all purposes of the Indenture
upon receipt by the Trustee, no later than the Business Day prior to the date
fixed for redemption, of a written notice from the Administrative Agent
withdrawing said Redemption Demand.

      The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

       

      No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

       

      This Bond is
nontransferable except to effect transfer to any successor to the Administrative
Agent under the Reimbursement Agreement, but is exchangeable by the registered
holder hereof, in person or by attorney duly authorized, at the Corporate Trust
Office of the Trustee, any such permitted transfer or exchange to be made in the
manner and upon the conditions prescribed in the Indenture, upon the surrender
and cancellation of this Bond and the payment of any applicable taxes and fees
required by law, and upon any such transfer or exchange a new registered Bond or
Bonds of the same series and tenor, will be issued to the authorized transferee,
or the registered holder, as the case may be. The Company and the Trustee may
deem and treat the person in whose name this Bond is registered as the absolute
owner for the purpose of
receiving payment of or on account of the principal and interest due hereon and
for all other purposes.

       

      This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

      

      IN WITNESS WHEREOF,
the Company has caused this Bond to be executed in its name by the manual or
facsimile signature of an Authorized Executive Officer and attested by the
manual or facsimile signature of another Authorized Executive
Officer.

which provides for certain credits towards payment of principal of, and interest
on, the Bonds of this series.  No payment of principal under such
Tender Advances or demand loans or hereunder shall reduce the stated principal
amount of the Bonds of this series unless, and only to the extent that, the
Reimbursement Agreement shall be terminated concurrently therewith in accordance
with the provisions of Section 2.02(c) of the Reimbursement

need not continue.  The interest on each Bond of this series so
payable on any Interest Payment Date shall, subject to the exceptions provided
in Section 3.07 of the Indenture (as hereinafter defined) and to the provisions

Reimbursement Agreement, the date on which any such interest is due under and as
provided in the Reimbursement Agreement, and (ii) in the case of Obligations
other than (x) interest covered by the preceding clause (i) and (y) Tender

applicable date for the payment of such Obligations under the Reimbursement
Agreement.  As used herein, the terms “Available

“Commitments,”
“Letter of
Credit,” “Obligations,” and “Tender
Advances” shall have the respective meanings set forth in the
Reimbursement Agreement.  The Letter of Credit was issued in favor of
the bond trustee for $99,100,000 aggregate principal amount of State of Ohio
Pollution Control Revenue Refunding Bonds, Series 2005-A (FirstEnergy Nuclear

      This Bond is one of

under and secured by an Open-End Mortgage, General Mortgage Indenture and Deed
of Trust, dated as of June 1, 2009, duly executed by the Company to The Bank of
New York Mellon Trust Company, N.A., a national banking association organized

      conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, such Bonds may be in various principal sums, are
issuable in series, may mature at different times, may bear interest at
different rates and may otherwise vary as therein provided; and this Bond is one
Bond of a series entitled “First Mortgage Bonds, Collateral Series C of 2009 due
2010,” created by the Supplemental Indenture, as provided for in the Indenture,
and authorized for issuance in an aggregate principal amount of up to
$100,078,000.

       

      Any payment of
Obligations made by or on behalf of the Company in respect of the Reimbursement
Agreement shall be deemed a payment in respect of this Bond, but such payment
shall not reduce the principal amount of this Bond then in effect unless the sum
of (a) the Available Amount of the Letter of Credit outstanding at such time,
plus (b) the aggregate principal amount of all Tender Advances which are then
outstanding under the Reimbursement Agreement, plus (c) the aggregate amount of
all other reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement which are
outstanding at such time, is irrevocably reduced concurrently with such payment;
provided,
however,
if after a drawing under the Letter of Credit, the Letter of Credit shall have
been reinstated in respect of such drawing prior to the Administrative Agent,
Fronting Bank or Banks having received reimbursement for such drawing from the
Company, the reimbursement of such reinstated amount shall not reduce the
principal amount of this Bond.  In the event that all of the Company's
obligations under the Reimbursement Agreement have been discharged and the
Letter of Credit shall have been cancelled and returned to the Fronting Bank,
this Bond shall be deemed paid in full and the Holder shall surrender this Bond
to the Trustee for cancellation.

       

      The Bonds of this
series shall be redeemed promptly, without notice, by the Company in whole at
100% of the principal amount thereof plus accrued interest to the date of
redemption (the “Redemption
Price”) following receipt by the Trustee of written demand for redemption
(a “Redemption
Demand”)  from an authorized representative of the
Administrative Agent under the Reimbursement Agreement stating that (i) all of
the Obligations under the Reimbursement Agreement have become or have been
declared to be immediately due and payable as a result of the occurrence and
continuance of an “Event of Default” under the Reimbursement Agreement and (ii)
that the Administrative Agent has demanded payment thereof from the Company;
provided that the Bonds
of this series shall be redeemed automatically by the Company, without any
notice to any person, in whole at the Redemption Price, if the Obligations under
the Reimbursement Agreement have become immediately due and payable as a result
of the occurrence of an “Event of Default” under the Reimbursement Agreement
with respect to the Company (but not any subsidiary thereof) under Section
6.01(f) of the Reimbursement Agreement.  Such redemption shall be
effected on the fifth Business Day following receipt by the Trustee of the
Redemption Demand, if such Redemption Demand is required, or the occurrence of
an “Event of Default” under the Reimbursement Agreement with respect to the
Company (but not any subsidiary thereof) under Section 6.01(f) of the
Reimbursement Agreement.  Any payment of the Redemption Price made to
the Administrative Agent shall constitute a payment by the Company in respect of

      FIRSTENERGY NUCLEAR GENERATION

successors and assigns, the “Company”),
for value received promises to pay to [________], as Administrative Agent (the
“Administrative
Agent”) under that certain Letter of Credit and Reimbursement Agreement,
dated as of December 16, 2005, among the Company, Barclays Bank PLC, acting
through its New York Branch, as Fronting Bank and Administrative Agent and the
Banks parties thereto from time to time (such Reimbursement Agreement, as
amended from time to time, hereinafter the “Reimbursement
Agreement”), or registered assigns, on December 16, 2010, the principal
sum of [_____________________] Dollars or, at any time (if less), such lesser
principal amount as is equal to the sum of (a) the Available Amount of the
Letter of Credit outstanding at such time, plus (b) the aggregate principal
amount of all Tender Advances which are outstanding at such time, plus (c) the
aggregate amount of all other reimbursement obligations of the Company to the
Banks constituting demand loans pursuant to Section 2.04 of the Reimbursement
Agreement which are outstanding at such time, on such date or dates and in such
amounts as set forth in the Reimbursement Agreement for the payment of principal
on such Tender Advances and demand loans, and to pay interest on said principal
amount from the date hereof at such rate or rates per annum on each day as
shall cause the amount of interest payable on the Bonds of this series on an
Interest Payment Date (as hereinafter defined) to equal the amount of
outstanding Obligations (other than Tender Advances or reimbursement obligations
of the Company to the Banks constituting demand loans pursuant to Section 2.04
of the Reimbursement Agreement) payable on such Interest Payment Date; provided,
however,
that such interest rate or rates shall not exceed ten percent (10%) per annum
(calculated on the basis of a year of 360 days for the actual

      days elapsed). Said interest shall accrue
hereon until the principal hereof shall be paid in full, subject to Section 2.04
of the First Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental
Indenture”),
executed and delivered by the Company to the Trustee (as hereinafter defined),
which provides for certain credits towards payment of principal of, and interest
on, the Bonds of this series.  No payment of principal under such
Tender Advances or demand loans or hereunder shall reduce the stated principal
amount of the Bonds of this series unless, and only to the extent that, the
Reimbursement Agreement shall be terminated concurrently therewith in accordance
with the provisions of Section 2.02(c) of the Reimbursement
Agreement.  Interest shall accrue on the Bonds of this series from the
date of issuance hereof, and the payment thereof shall be credited as provided
in Section 2.04(a) of the Supplemental Indenture unless and until the Trustee
receives the notice contemplated by Section 2.04(b) of the Supplemental
Indenture, whereupon the interest on the Bonds of this series shall become and
remain due and payable until such time as the Trustee receives a further written
notice (including a telecopy or other form of written telecommunication) from an
authorized representative of the Administrative Agent stating that such payments
need not continue.  The interest on each Bond of this series so
payable on any Interest Payment Date shall, subject to the exceptions provided
in Section 3.07 of the Indenture (as hereinafter defined) and to the provisions
of Section 2.04 of the Supplemental Indenture, be paid to the person in whose
name such Bond is registered on the date of such payment.  The
principal of, and the interest on, this Bond shall be payable at the office or
agency of the Company in the City of Cleveland, State of Ohio in any coin or
currency of the United States of America which at the time of payment is legal
tender for the payment of public and private debts.

       

      As used herein,
“Interest
Payment Date” shall mean (i) in the case of Obligations representing
interest payable on Tender Advances or on reimbursement obligations of the
Company to the Banks constituting demand loans pursuant to Section 2.04 of the
Reimbursement Agreement, the date on which any such interest is due under and as
provided in the Reimbursement Agreement, and (ii) in the case of Obligations
other than (x) interest covered by the preceding clause (i) and (y) Tender
Advances or reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement, the
applicable date for the payment of such Obligations under the Reimbursement
Agreement.  As used herein, the terms “Available
Amount,” “Banks,”
“Commitments,”
“Letter of
Credit,” “Obligations,” and “Tender
Advances” shall have the respective meanings set forth in the
Reimbursement Agreement.  The Letter of Credit was issued in favor of
the bond trustee for $82,800,000 aggregate principal amount of State of Ohio
Pollution Control Revenue Refunding Bonds, Series 2005-B (FirstEnergy Nuclear
Generation Corp. Project) issued by the Ohio Water Development
Authority.

       

      This Bond is one of
an issue of Bonds of the Company issued and to be issued in one or more series
under and secured by an Open-End Mortgage, General Mortgage Indenture and Deed
of Trust, dated as of June 1, 2009, duly executed by the Company to The Bank of
New York Mellon Trust Company, N.A., a national banking association organized
and existing under the laws of the United States of America, as Trustee (the
“Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the Supplemental Indenture, to which Open-End Mortgage, General Mortgage
Indenture and Deed of Trust and all indentures supplemental thereto
(collectively referred to as the “Indenture”)
reference is hereby made for a description of the property mortgaged and
pledged, the nature and extent of the security, the terms and

      conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, such Bonds may be in various principal sums, are
issuable in series, may mature at different times, may bear interest at
different rates and may otherwise vary as therein provided; and this Bond is one
Bond of a series entitled “First Mortgage Bonds, Collateral Series D of 2009 due
2010,” created by the Supplemental Indenture, as provided for in the Indenture,
and authorized for issuance in an aggregate principal amount of up to
$83,617,000.

       

      Any payment of
Obligations made by or on behalf of the Company in respect of the Reimbursement
Agreement shall be deemed a payment in respect of this Bond, but such payment
shall not reduce the principal amount of this Bond then in effect unless the sum
of (a) the Available Amount of the Letter of Credit outstanding at such time,
plus (b) the aggregate principal amount of all Tender Advances which are then
outstanding under the Reimbursement Agreement, plus (c) the aggregate amount of
all other reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement which are
outstanding at such time, is irrevocably reduced concurrently with such payment;
provided,
however,
if after a drawing under the Letter of Credit, the Letter of Credit shall have
been reinstated in respect of such drawing prior to the Administrative Agent,
Fronting Bank or Banks having received reimbursement for such drawing from the
Company, the reimbursement of such reinstated amount shall not reduce the
principal amount of this Bond.  In the event that all of the Company's
obligations under the Reimbursement Agreement have been discharged and the
Letter of Credit shall have been cancelled and returned to the Fronting Bank,
this Bond shall be deemed paid in full and the Holder shall surrender this Bond
to the Trustee for cancellation.

       

      The Bonds of this
series shall be redeemed promptly, without notice, by the Company in whole at
100% of the principal amount thereof plus accrued interest to the date of
redemption (the “Redemption
Price”) following receipt by the Trustee of written demand for redemption
(a “Redemption
Demand”)  from an authorized representative of the
Administrative Agent under the Reimbursement Agreement stating that (i) all of
the Obligations under the Reimbursement Agreement have become or have been
declared to be immediately due and payable as a result of the occurrence and
continuance of an “Event of Default” under the Reimbursement Agreement and (ii)
that the Administrative Agent has demanded payment thereof from the Company;
provided that the Bonds
of this series shall be redeemed automatically by the Company, without any
notice to any person, in whole at the Redemption Price, if the Obligations under
the Reimbursement Agreement have become immediately due and payable as a result
of the occurrence of an “Event of Default” under the Reimbursement Agreement
with respect to the Company (but not any subsidiary thereof) under Section
6.01(f) of the Reimbursement Agreement.  Such redemption shall be
effected on the fifth Business Day following receipt by the Trustee of the
Redemption Demand, if such Redemption Demand is required, or the occurrence of
an “Event of Default” under the Reimbursement Agreement with respect to the
Company (but not any subsidiary thereof) under Section 6.01(f) of the
Reimbursement Agreement.  Any payment of the Redemption Price made to
the Administrative Agent shall constitute a payment by the Company in respect of
Obligations under the Reimbursement Agreement.  A Redemption Demand
shall be rescinded and shall be null and void for all purposes of the Indenture
upon receipt by the Trustee, no later than the Business Day prior to
the

       date fixed for
redemption, of a written notice from the Administrative Agent withdrawing said
Redemption Demand.

       

       

      The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

       

      No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

       

      This Bond is
nontransferable except to effect transfer to any successor to the Administrative
Agent under the Reimbursement Agreement, but is exchangeable by the registered
holder hereof, in person or by attorney duly authorized, at the Corporate Trust
Office of the Trustee, any such permitted transfer or exchange to be made in the
manner and upon the conditions prescribed in the Indenture, upon the surrender
and cancellation of this Bond and the payment of any applicable taxes and fees
required by law, and upon any such transfer or exchange a new registered Bond or
Bonds of the same series and tenor, will be issued to the authorized transferee,
or the registered holder, as the case may be. The Company and the Trustee may
deem and treat the person in whose name this Bond is registered as the absolute
owner for the purpose of
receiving payment of or on account of the principal and interest due hereon and
for all other purposes.

       

      This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

      

      IN WITNESS WHEREOF,
the Company has caused this Bond to be executed in its name by the manual or
facsimile signature of an Authorized Executive Officer and attested by the
manual or facsimile signature of another Authorized Executive
Officer.

sum of [_____________________] Dollars or, at any time (if less), such lesser
principal amount as is equal to the sum of (a) the Available Amount of the

amount of all Tender Advances which are outstanding at such time, plus (c) the
aggregate amount of all other reimbursement obligations of the Company to the
Banks constituting demand loans pursuant to Section 2.04 of the Reimbursement

outstanding Obligations (other than Tender Advances or reimbursement obligations
of the Company to the Banks constituting demand loans pursuant to Section 2.04
of the Reimbursement Agreement) payable on such Interest Payment Date; provided,

Section 2.04 of the First Supplemental Indenture dated as of June 15, 2009 (as
amended, supplemented, modified or restated, the “Supplemental
Indenture”),

which provides for certain credits towards payment of principal of, and interest
on, the Bonds of this series.  No payment of principal under such

amount of the Bonds of this series unless, and only to the extent that, the
Reimbursement Agreement shall be terminated concurrently therewith in accordance
with the provisions of Section 2.02(c) of the Reimbursement
Agreement.  Interest shall accrue on the Bonds of this series from the

authorized representative of the Administrative Agent stating that such payments
need not continue.  The interest on each Bond of this series so
payable on any Interest Payment Date shall, subject to the exceptions provided

      As used herein,
“Interest
Payment Date” shall mean (i) in the case of Obligations representing
interest payable on Tender Advances or on reimbursement obligations of the
Company to the Banks constituting demand loans pursuant to Section 2.04 of the
Reimbursement Agreement, the date on which any such interest is due under and as
provided in the Reimbursement Agreement, and (ii) in the case of Obligations
other than (x) interest covered by the preceding clause (i) and (y) Tender
Advances or reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement, the
applicable date for the payment of such Obligations under the Reimbursement
Agreement.  As used herein, the terms “Available
Amount,” “Banks,”
“Commitments,”
“Letter of
Credit,” “Obligations,” and “Tender
Advances” shall have the respective meanings set forth in the
Reimbursement Agreement.  The Letter of Credit was issued in favor of
the bond trustee for $72,650,000 aggregate principal amount of Beaver County
Pollution Control Revenue Refunding Bonds, Series 2005-A (FirstEnergy Nuclear
Generation Corp. Project) issued by the Beaver County Industrial Development
Authority.

       

      This Bond is one of
an issue of Bonds of the Company issued and to be issued in one or more series
under and secured by an Open-End Mortgage, General Mortgage Indenture and Deed
of Trust, dated as of June 1, 2009, duly executed by the Company to The Bank of
New York Mellon Trust Company, N.A., a national banking association organized
and existing under the laws of the United States of America, as Trustee (the
“Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the Supplemental Indenture, to which Open-End Mortgage, General Mortgage
Indenture and Deed of Trust and all indentures supplemental thereto
(collectively referred to as the “Indenture”)
reference is hereby made for a description of the property mortgaged and
pledged, the nature and extent of the security, the terms and

       conditions
upon which such Bonds are, and are to be, issued and secured, and the rights of
the owners of such Bonds and the Trustee in respect of such
security.  As provided in the Indenture, such Bonds may be in various
principal sums, are issuable in series, may mature at different times, may bear
interest at different rates and may otherwise vary as therein provided; and this
Bond is one Bond of a series entitled “First Mortgage Bonds, Collateral Series E
of 2009 due 2010,” created by the Supplemental Indenture, as provided for in the
Indenture, and authorized for issuance in an aggregate principal amount of up to
$73,367,000.

       

      Any payment of
Obligations made by or on behalf of the Company in respect of the Reimbursement
Agreement shall be deemed a payment in respect of this Bond, but such payment
shall not reduce the principal amount of this Bond then in effect unless the sum
of (a) the Available Amount of the Letter of Credit outstanding at such time,
plus (b) the aggregate principal amount of all Tender Advances which are then
outstanding under the Reimbursement Agreement, plus (c) the aggregate amount of
all other reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement which are
outstanding at such time, is irrevocably reduced concurrently with such payment;
provided,
however,
if after a drawing under the Letter of Credit, the Letter of Credit shall have
been reinstated in respect of such drawing prior to the Administrative Agent,
Fronting Bank or Banks having received reimbursement for such drawing from the
Company, the reimbursement of such reinstated amount shall not reduce the
principal amount of this Bond.  In the event that all of the Company's
obligations under the Reimbursement Agreement have been discharged and the
Letter of Credit shall have been cancelled and returned to the Fronting Bank,
this Bond shall be deemed paid in full and the Holder shall surrender this Bond
to the Trustee for cancellation.

       

      The Bonds of this
series shall be redeemed promptly, without notice, by the Company in whole at
100% of the principal amount thereof plus accrued interest to the date of
redemption (the “Redemption
Price”) following receipt by the Trustee of written demand for redemption
(a “Redemption
Demand”)  from an authorized representative of the
Administrative Agent under the Reimbursement Agreement stating that (i) all of
the Obligations under the Reimbursement Agreement have become or have been
declared to be immediately due and payable as a result of the occurrence and
continuance of an “Event of Default” under the Reimbursement Agreement and (ii)
that the Administrative Agent has demanded payment thereof from the Company;
provided that the Bonds
of this series shall be redeemed automatically by the Company, without any
notice to any person, in whole at the Redemption Price, if the Obligations under
the Reimbursement Agreement have become immediately due and payable as a result
of the occurrence of an “Event of Default” under the Reimbursement Agreement
with respect to the Company (but not any subsidiary thereof) under Section
6.01(f) of the Reimbursement Agreement.  Such redemption shall be
effected on the fifth Business Day following receipt by the Trustee of the
Redemption Demand, if such Redemption Demand is required, or the occurrence of
an “Event of Default” under the Reimbursement Agreement with respect to the
Company (but not any subsidiary thereof) under Section 6.01(f) of the
Reimbursement Agreement.  Any payment of the Redemption Price made to
the Administrative Agent shall constitute a payment by the Company in respect of
Obligations under the Reimbursement Agreement.  A Redemption Demand
shall be rescinded and shall be null and void for all purposes of the Indenture
upon receipt by the Trustee, no later than the Business Day prior to
the

       date fixed for
redemption, of a written notice from the Administrative Agent withdrawing said
Redemption Demand.

       

       

      The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

       

      No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

       

      This Bond is
nontransferable except to effect transfer to any successor to the Administrative
Agent under the Reimbursement Agreement, but is exchangeable by the registered
holder hereof, in person or by attorney duly authorized, at the Corporate Trust
Office of the Trustee, any such permitted transfer or exchange to be made in the
manner and upon the conditions prescribed in the Indenture, upon the surrender
and cancellation of this Bond and the payment of any applicable taxes and fees
required by law, and upon any such transfer or exchange a new registered Bond or
Bonds of the same series and tenor, will be issued to the authorized transferee,
or the registered holder, as the case may be. The Company and the Trustee may
deem and treat the person in whose name this Bond is registered as the absolute
owner for the purpose of
receiving payment of or on account of the principal and interest due hereon and
for all other purposes.

       

      This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

      

      IN WITNESS WHEREOF,
the Company has caused this Bond to be executed in its name by the manual or
facsimile signature of an Authorized Executive Officer and attested by the
manual or facsimile signature of another Authorized Executive
Officer.

      such Bonds may be in
various principal sums, are issuable in series, may mature at different times,
may bear interest at different rates and may otherwise vary as therein provided;
and this Bond is one Bond of a series entitled “First Mortgage Bonds, Collateral
Series F of 2009 due 2011,” created by the Supplemental Indenture, as provided
for in the Indenture, and authorized for issuance in an aggregate principal
amount of up to $46,959,000.

       

      Any payment of
Obligations made by or on behalf of the Company in respect of the Reimbursement
Agreement shall be deemed a payment in respect of this Bond, but such payment
shall not reduce the principal amount of this Bond then in effect unless the sum
of (a) the Available Amount of the Letter of Credit outstanding at such time,
plus (b) the aggregate principal amount of all Tender Advances which are then
outstanding under the Reimbursement Agreement, plus (c) the aggregate amount of
all other reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement which are
outstanding at such time, is irrevocably reduced concurrently with such payment;
provided,
however,
if after a drawing under the Letter of Credit, the Letter of Credit shall have
been reinstated in respect of such drawing prior to the Administrative Agent,
Fronting Bank or Banks having received reimbursement for such drawing from the
Company, the reimbursement of such reinstated amount shall not reduce the
principal amount of this Bond.  In the event that all of the Company's
obligations under the Reimbursement Agreement have been discharged and the
Letter of Credit shall have been cancelled and returned to the Fronting Bank,
this Bond shall be deemed paid in full and the Holder shall surrender this Bond
to the Trustee for cancellation.

       

      The Bonds of this
series shall be redeemed promptly, without notice, by the Company in whole at
100% of the principal amount thereof plus accrued interest to the date of
redemption (the “Redemption
Price”) following receipt by the Trustee of written demand for redemption
(a “Redemption
Demand”)  from an authorized representative of the
Administrative Agent under the Reimbursement Agreement stating that (i) all of
the Obligations under the Reimbursement Agreement have become or have been
declared to be immediately due and payable as a result of the occurrence and
continuance of an “Event of Default” under the Reimbursement Agreement and (ii)
that the Administrative Agent has demanded payment thereof from the Company;
provided that the Bonds
of this series shall be redeemed automatically by the Company, without any
notice to any person, in whole at the Redemption Price, if the Obligations under
the Reimbursement Agreement have become immediately due and payable as a result
of the occurrence of an “Event of Default” under the Reimbursement Agreement
with respect to the Company (but not any subsidiary thereof) under Section
6.01(f) of the Reimbursement Agreement.  Such redemption shall be
effected on the fifth Business Day following receipt by the Trustee of the
Redemption Demand, if such Redemption Demand is required, or the occurrence of
an “Event of Default” under the Reimbursement Agreement with respect to the
Company (but not any subsidiary thereof) under Section 6.01(f) of the
Reimbursement Agreement.  Any payment of the Redemption Price made to
the Administrative Agent shall constitute a payment by the Company in respect of
Obligations under the Reimbursement Agreement.  A Redemption Demand
shall be rescinded and shall be null and void for all purposes of the Indenture
upon receipt by the Trustee, no later than the Business Day prior to the date
fixed for redemption, of a written notice from the Administrative Agent
withdrawing said Redemption Demand.

      The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

       

      No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

       

      This Bond is
nontransferable except to effect transfer to any successor to the Administrative
Agent under the Reimbursement Agreement, but is exchangeable by the registered
holder hereof, in person or by attorney duly authorized, at the Corporate Trust
Office of the Trustee, any such permitted transfer or exchange to be made in the
manner and upon the conditions prescribed in the Indenture, upon the surrender
and cancellation of this Bond and the payment of any applicable taxes and fees
required by law, and upon any such transfer or exchange a new registered Bond or
Bonds of the same series and tenor, will be issued to the authorized transferee,
or the registered holder, as the case may be. The Company and the Trustee may
deem and treat the person in whose name this Bond is registered as the absolute
owner for the purpose of
receiving payment of or on account of the principal and interest due hereon and
for all other purposes.

       

      This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

      

      IN WITNESS WHEREOF,
the Company has caused this Bond to be executed in its name by the manual or
facsimile signature of an Authorized Executive Officer and attested by the

“Administrative
Agent”) under that certain Letter of Credit and Reimbursement Agreement,
dated as of April 3, 2006, among the Company, Barclays Bank PLC, acting through
its New York Branch, as Fronting Bank and Administrative Agent, KeyBank National
Association, as Syndication Agent, and the Banks parties thereto from time to
time (such Reimbursement Agreement, as amended from time to time, hereinafter
the “Reimbursement
Agreement”), or registered assigns, on April 1, 2011, the principal sum
of [_____________________] Dollars or, at any time (if less), such lesser
principal amount as is equal to the sum of (a) the Available Amount of the
Letter of Credit outstanding at such time, plus (b) the aggregate principal
amount of all Tender Advances which are outstanding at such time, plus (c) the
aggregate amount of all other reimbursement obligations of the Company to the
Banks constituting demand loans pursuant to Section 2.04 of the Reimbursement
Agreement which are outstanding at such time, on such date or dates and in such
amounts as set forth in the Reimbursement Agreement for the payment of principal
on such Tender Advances and demand loans, and to pay interest on said principal
amount from the date hereof at such rate or rates per annum on each day as
shall cause the amount of interest payable on the Bonds of this series on an
Interest Payment Date (as hereinafter defined) to equal the amount of
outstanding Obligations (other than Tender Advances or reimbursement obligations
of the Company to the Banks constituting demand loans pursuant to Section 2.04
of the Reimbursement Agreement) payable on such Interest Payment Date; provided,
however,
that such interest rate or rates shall not exceed ten percent (10%) per annum
(calculated on the basis of a year of 360 days for the actual

hereon until the principal hereof shall be paid in full, subject to Section 2.04
of the First Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental
Indenture”),
executed and delivered by the Company to the Trustee (as hereinafter defined),
which provides for certain credits towards payment of principal of, and interest
on, the Bonds of this series.  No payment of principal under such
Tender Advances or demand loans or hereunder shall reduce the stated principal
amount of the Bonds of this series unless, and only to the extent that, the
Reimbursement Agreement shall be terminated concurrently therewith in accordance
with the provisions of Section 2.02(c) of the Reimbursement
Agreement.  Interest shall accrue on the Bonds of this series from the
date of issuance hereof, and the payment thereof shall be credited as provided
in Section 2.04(a) of the Supplemental Indenture unless and until the Trustee
receives the notice contemplated by Section 2.04(b) of the Supplemental
Indenture, whereupon the interest on the Bonds of this series shall become and
remain due and payable until such time as the Trustee receives a further written
notice (including a telecopy or other form of written telecommunication) from an
authorized representative of the Administrative Agent stating that such payments
need not continue.  The interest on each Bond of this series so
payable on any Interest Payment Date shall, subject to the exceptions provided
in Section 3.07 of the Indenture (as hereinafter defined) and to the provisions
of Section 2.04 of the Supplemental Indenture, be paid to the person in whose
name such Bond is registered on the date of such payment.  The
principal of, and the interest on, this Bond shall be payable at the office or
agency of the Company in the City of Cleveland, State of Ohio in any coin or
currency of the United States of America which at the time of payment is legal
tender for the payment of public and private debts.

       

      As used herein,
“Interest
Payment Date” shall mean (i) in the case of Obligations representing
interest payable on Tender Advances or on reimbursement obligations of the
Company to the Banks constituting demand loans pursuant to Section 2.04 of the
Reimbursement Agreement, the date on which any such interest is due under and as
provided in the Reimbursement Agreement, and (ii) in the case of Obligations
other than (x) interest covered by the preceding clause (i) and (y) Tender
Advances or reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement, the
applicable date for the payment of such Obligations under the Reimbursement
Agreement.  As used herein, the terms “Available
Amount,” “Banks,”
“Commitments,”
“Letter of
Credit,” “Obligations,” and “Tender
Advances” shall have the respective meanings set forth in the
Reimbursement Agreement.  The Letter of Credit was issued in favor of
the bond trustee for $60,000,000 aggregate principal amount of Beaver County
Pollution Control Revenue Refunding Bonds, Series 2006-A (FirstEnergy Nuclear
Generation Corp. Project) issued by the Beaver County Industrial Development
Authority.

       

      This Bond is one of
an issue of Bonds of the Company issued and to be issued in one or more series
under and secured by an Open-End Mortgage, General Mortgage Indenture and Deed
of Trust, dated as of June 1, 2009, duly executed by the Company to The Bank of
New York Mellon Trust Company, N.A., a national banking association organized
and existing under the laws of the United States of America, as Trustee (the

      conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, such Bonds may be in various principal sums, are
issuable in series, may mature at different times, may bear interest at
different rates and may otherwise vary as therein provided; and this Bond is one
Bond of a series entitled “First Mortgage Bonds, Collateral Series G of 2009 due
2011,” created by the Supplemental Indenture, as provided for in the Indenture,
and authorized for issuance in an aggregate principal amount of up to
$60,592,000.

       

      Any payment of
Obligations made by or on behalf of the Company in respect of the Reimbursement
Agreement shall be deemed a payment in respect of this Bond, but such payment
shall not reduce the principal amount of this Bond then in effect unless the sum
of (a) the Available Amount of the Letter of Credit outstanding at such time,
plus (b) the aggregate principal amount of all Tender Advances which are then
outstanding under the Reimbursement Agreement, plus (c) the aggregate amount of
all other reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement which are
outstanding at such time, is irrevocably reduced concurrently with such payment;
provided,
however,
if after a drawing under the Letter of Credit, the Letter of Credit shall have
been reinstated in respect of such drawing prior to the Administrative Agent,
Fronting Bank or Banks having received reimbursement for such drawing from the
Company, the reimbursement of such reinstated amount shall not reduce the
principal amount of this Bond.  In the event that all of the Company's
obligations under the Reimbursement Agreement have been discharged and the
Letter of Credit shall have been cancelled and returned to the Fronting Bank,
this Bond shall be deemed paid in full and the Holder shall surrender this Bond
to the Trustee for cancellation.

       

      The Bonds of this
series shall be redeemed promptly, without notice, by the Company in whole at
100% of the principal amount thereof plus accrued interest to the date of
redemption (the “Redemption
Price”) following receipt by the Trustee of written demand for redemption
(a “Redemption
Demand”)  from an authorized representative of the
Administrative Agent under the Reimbursement Agreement stating that (i) all of
the Obligations under the Reimbursement Agreement have become or have been
declared to be immediately due and payable as a result of the occurrence and
continuance of an “Event of Default” under the Reimbursement Agreement and (ii)
that the Administrative Agent has demanded payment thereof from the Company;
provided that the Bonds
of this series shall be redeemed automatically by the Company, without any
notice to any person, in whole at the Redemption Price, if the Obligations under
the Reimbursement Agreement have become immediately due and payable as a result
of the occurrence of an “Event of Default” under the Reimbursement Agreement
with respect to the Company (but not any subsidiary thereof) under Section
6.01(f) of the Reimbursement Agreement.  Such redemption shall be
effected on the fifth Business Day following receipt by the Trustee of the
Redemption Demand, if such Redemption Demand is required, or the occurrence of
an “Event of Default” under the Reimbursement Agreement with respect to the
Company (but not any subsidiary thereof) under Section 6.01(f) of the
Reimbursement Agreement.  Any payment of the Redemption Price made to
the Administrative Agent shall constitute a payment by the Company in respect of
Obligations under the Reimbursement Agreement.  A Redemption Demand
shall be rescinded and shall be null and void for all purposes of the Indenture
upon receipt by the Trustee, no later than the Business Day prior to the

      date fixed for
redemption, of a written notice from the Administrative Agent withdrawing said
Redemption Demand.

       

       

      The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

       

      No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

       

      This Bond is
nontransferable except to effect transfer to any successor to the Administrative
Agent under the Reimbursement Agreement, but is exchangeable by the registered
holder hereof, in person or by attorney duly authorized, at the Corporate Trust
Office of the Trustee, any such permitted transfer or exchange to be made in the
manner and upon the conditions prescribed in the Indenture, upon the surrender
and cancellation of this Bond and the payment of any applicable taxes and fees
required by law, and upon any such transfer or exchange a new registered Bond or
Bonds of the same series and tenor, will be issued to the authorized transferee,
or the registered holder, as the case may be. The Company and the Trustee may
deem and treat the person in whose name this Bond is registered as the absolute
owner for the purpose of
receiving payment of or on account of the principal and interest due hereon and
for all other purposes.

       

      This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

      

      IN WITNESS WHEREOF,
the Company has caused this Bond to be executed in its name by the manual or
facsimile signature of an Authorized Executive Officer and attested by the
manual or facsimile signature of another Authorized Executive

    This Bond is one of
an issue of Bonds of the Company known as its First Mortgage Bonds, issued and
to be issued in one or more series under and secured by an Open-End Mortgage,
General Mortgage Indenture and Deed of Trust, dated as of June 19, 2008, duly
executed by the Company to The Bank of New York Mellon Trust Company, N.A.
(formerly known as The Bank of New York Trust Company, N.A.), a national banking
association organized and existing under the laws of the United States of
America, as Trustee (the “Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the Fourth Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental
Indenture”), to
which Open-End Mortgage, General Mortgage Indenture and Deed of Trust and all
indentures supplemental thereto (collectively referred to as the “Indenture”)
reference is hereby made for a description of the property mortgaged and
pledged, the nature and extent of the security, the terms and conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, such Bonds may be in various principal sums, are
issuable in series, may mature at different times, may bear interest at
different rates and may otherwise vary as therein provided; and this Bond is one
Bond of a series entitled “First Mortgage Bonds, Guarantee Series C of 2009 due
2018,” created by the Supplemental Indenture, as provided for in the Indenture,
and authorized for issuance in an aggregate principal amount of up to
$141,260,000.

     

    If and when the
principal of any Revenue Bonds is paid, then there is deemed to be paid an equal
principal amount of the Bonds of this series then outstanding; provided,
however, that such payment of the Bonds of this series is deemed to be made only
when and to the extent that notice of such payment of such Revenue Bonds is
given by the Company to the Trustee.

     

    The Bonds of this
series shall be redeemed by the Company in whole at any time prior to maturity
at a redemption price of 100% of the principal amount thereof plus accrued and
unpaid interest to the date of redemption following receipt by the Trustee of
written demand for redemption (a “Redemption
Demand”) from an authorized representative of the Revenue Bond Trustee
under the Revenue Bond Indenture stating that the principal amount of all the
Revenue Bonds then outstanding under the Revenue Bond Indenture has been
declared due and payable pursuant to the provisions of Section 9.02 of the
Revenue Bond Indenture, specifying the date of the accelerated maturity of such
Revenue Bonds and the date from which interest on the Revenue Bonds has then
accrued and is unpaid, stating such declaration of maturity has not been
annulled and demanding payment of the principal amount of the Bonds of this
series plus accrued interest thereon to the date fixed for such redemption. The
date fixed for such redemption shall be set forth in the aforesaid Redemption
Demand and shall not be earlier than the date specified in such Redemption
Demand as the date of accelerated maturity of the Revenue Bonds then outstanding
under the Revenue Bond Indenture and not later than forty-five days after the
Trustee’s receipt of such Redemption Demand unless such forty-fifth day is
earlier than such date of accelerated maturity.  The Revenue Bond
Trustee as the sole holder of the Bonds of this series, and any successor
thereto, hereby irrevocably waives any requirement of notice of such redemption
under

    Section 5.04 of the
Indenture.  Upon receipt of the aforesaid Redemption Demand, the date
from which unpaid interest on the Revenue Bonds has then accrued (as specified
by the Revenue Bond Trustee in the Redemption Demand) shall become the initial
interest accrual date (the “Initial Interest
Accrual Date”) with respect to the Bonds of this series; provided,
however, on any demand for payment of the principal amount thereof at maturity
as a result of the principal of the Revenue Bonds becoming due and payable on
the maturity date of the Bonds of this series, the date from which unpaid
interest on the Revenue Bonds has then accrued shall become the Initial Interest
Accrual Date with respect to the Bonds of this series, such date to be as stated
in a written notice from the Revenue Bond Trustee to the
Trustee.  Such redemption shall become null and void for all purposes
under the Indenture (including the fixing of the Initial Interest Accrual Date
with respect to the Bonds of this series) upon receipt by the Trustee of written
notice from the Revenue Bond Trustee of the annulment of the acceleration of the
maturity of the Revenue Bonds then outstanding under the Revenue Bond Indenture
and of the rescission of the aforesaid Redemption Demand prior to the redemption
date specified in the Redemption Demand, and thereupon no redemption of the
Bonds of this series and no payment in respect thereof as specified in the
Redemption Demand, shall be effected or required.  But no such
rescission shall extend to any subsequent Redemption Demand from the Revenue
Bond Trustee or impair any right consequent on any such subsequent Redemption
Demand.

     

    The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

    

    No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

    

    This Bond is
nontransferable except to (i) effect transfer to any successor to the Revenue
Bond Trustee under the Revenue Bond Indenture, (ii) in connection with the
exercise of the rights and remedies of the holder hereof consequent upon an
“Event of Default” as defined in the Indenture or (iii) as may be necessary to
comply with a final order of a court of competent jurisdiction in connection
with any bankruptcy or reorganization proceeding of the Company.  But
this Bond is exchangeable by the registered holder hereof, in person or by
attorney duly authorized, at the Corporate Trust Office of the Trustee, any such
permitted transfer or exchange to be made in the manner and upon the conditions
prescribed in the Indenture, upon the surrender and cancellation of this Bond
and the payment of any applicable taxes and fees required by law, and upon any
such transfer or exchange a new registered Bond or Bonds of the same series and
tenor, will be issued to the authorized transferee, or the registered holder, as
the case may be. The Company and the Trustee may deem and treat the person in
whose name this Bond is

    registered as the
absolute owner for the purpose
of receiving payment of or on account of the principal and interest due hereon
and for all other purposes.

    

    This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

    

    IN WITNESS WHEREOF,
the Company has caused this Bond to be executed in its name by the manual or
facsimile signature of an Authorized Executive Officer and attested by the
manual or facsimile signature of another Authorized Executive
Officer.

    This Bond is one of
an issue of Bonds of the Company known as its First Mortgage Bonds, issued and
to be issued in one or more series under and secured by an Open-End Mortgage,
General Mortgage Indenture and Deed of Trust, dated as of June 19, 2008, duly
executed by the Company to The Bank of New York Mellon Trust Company, N.A.
(formerly known as The Bank of New York Trust Company, N.A.), a national banking
association organized and existing under the laws of the United States of
America, as Trustee (the “Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the Fourth Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental
Indenture”), to
which Open-End Mortgage, General Mortgage Indenture and Deed of Trust and all
indentures supplemental thereto (collectively referred to as the “Indenture”)
reference is hereby made for a description of the property mortgaged and
pledged, the nature and extent of the security, the terms and conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, such Bonds may be in various principal sums, are
issuable in series, may mature at different times, may bear interest at
different rates and may otherwise vary as therein provided; and this Bond is one
Bond of a series entitled “First Mortgage Bonds, Guarantee Series D of 2009 due
2029,” created by the Supplemental Indenture, as provided for in the Indenture,
and authorized for issuance in an aggregate principal amount of up to
$100,000,000.

     

    If and when the
principal of any Revenue Bonds is paid, then there is deemed to be paid an equal
principal amount of the Bonds of this series then outstanding; provided,
however, that such payment of the Bonds of this series is deemed to be made only
when and to the extent that notice of such payment of such Revenue Bonds is
given by the Company to the Trustee.

     

    The Bonds of this
series shall be redeemed by the Company in whole at any time prior to maturity
at a redemption price of 100% of the principal amount thereof plus accrued and
unpaid interest to the date of redemption following receipt by the Trustee of
written demand for redemption (a “Redemption
Demand”) from an authorized representative of the Revenue Bond Trustee
under the Revenue Bond Indenture stating that the principal amount of all the
Revenue Bonds then outstanding under the Revenue Bond Indenture has been
declared due and payable pursuant to the provisions of Section 11.02 of the
Revenue Bond Indenture, specifying the date of the accelerated maturity of such
Revenue Bonds and the date or dates from which interest on the Revenue Bonds has
then accrued and is unpaid (specifying the rate or rates of such accrual and the
principal amount of the particular Revenue Bonds to which such rates apply),
stating such declaration of maturity has not been annulled and demanding payment
of the principal amount of the Bonds of this series plus accrued interest
thereon to the date fixed for such redemption. The date fixed for such
redemption shall be set forth in the aforesaid Redemption Demand and shall not
be earlier than the date specified in such Redemption Demand as the date of
accelerated maturity of the Revenue Bonds then outstanding under the Revenue
Bond Indenture and not later than forty-five days after the Trustee’s receipt of
such Redemption Demand unless such forty-fifth day is earlier than such date of
accelerated maturity.  The Revenue Bond Trustee as the sole holder of
the Bonds of this series, and any successor thereto, hereby irrevocably waives
any requirement of notice of such redemption under Section 5.04 of the
Indenture.  Upon receipt of the aforesaid Redemption Demand, the
earliest date from which unpaid interest on the Revenue Bonds has then accrued
(as specified by the Revenue Bond Trustee in the Redemption Demand) shall become
the initial interest accrual date (the “Initial

Date”) with respect to the Bonds of this series; provided, however, on
any demand for payment of the principal amount thereof at maturity as a result
of the principal of the Revenue Bonds becoming due and payable on the maturity
date of the Bonds of this series, the earliest date from which unpaid interest
on the Revenue Bonds has then accrued shall become the Initial Interest Accrual
Date with respect to the Bonds of this series, such date, together with each
other different date from which unpaid interest on the Revenue Bonds has then
accrued, to be as stated in a written notice from the Revenue Bond Trustee to
the Trustee, which notice shall also specify the rate or rates of such accrual
and the principal amount of the particular Revenue Bonds to which such rate or
rates apply.  Such redemption shall become null and void for all
purposes under the Indenture (including the fixing of the Initial Interest
Accrual Date with respect to the Bonds of this series) upon receipt by the
Trustee of written notice from the Revenue Bond Trustee of the annulment of the
acceleration of the maturity of the Revenue Bonds then outstanding under the
Revenue Bond Indenture and of the rescission of the aforesaid Redemption Demand
prior to the redemption date specified in the Redemption Demand, and thereupon
no redemption of the Bonds of this series and no payment in respect thereof as
specified in the Redemption Demand, shall be effected or
required.  But no such rescission shall extend to any subsequent
Redemption Demand from the Revenue Bond Trustee or impair any right consequent
on any such subsequent Redemption Demand.

     

    The “Revenue Bond
Interest Rate” shall be the same rate of interest per annum as is borne
by the Revenue Bonds; provided, however, that if there are different rates of
interest borne by the Revenue Bonds, or if interest is required to be paid on
the Revenue Bonds more frequently than on each February 1 or August 1, the
Revenue Bond Interest Rate shall be the rate that results in the total amount of
interest payable on an Interest Payment Date, a redemption date or at maturity,
as the case may be, or at any other time interest on this Bond is due and
payable, to be equal to the total amount of unpaid interest that has accrued on
all then outstanding Revenue Bonds.

     

    The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

    

    From and after the
Release Date (as defined in the Revenue Bond Indenture), the Bonds of this
series shall be deemed fully paid, satisfied and discharged and the obligation
of the Company thereunder shall be terminated.  On the Release Date or
promptly following, the Bonds of this series shall be surrendered to and
cancelled by the Trustee.

    

    No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

Bond Trustee under the Revenue Bond Indenture, (ii) in connection with the
exercise of the rights and remedies of the holder hereof consequent upon an
“Event of Default” as defined in the Indenture or (iii) as may be necessary to
comply with a final order of a court of competent jurisdiction in connection
with any bankruptcy or reorganization proceeding of the Company.  But
this Bond is exchangeable by the registered holder hereof, in person or by
attorney duly authorized, at the Corporate Trust Office of the Trustee, any such
permitted transfer or exchange to be made in the manner and upon the conditions
prescribed in the Indenture, upon the surrender and cancellation of this Bond
and the payment of any applicable taxes and fees required by law, and upon any
such transfer or exchange a new registered Bond or Bonds of the same series and
tenor, will be issued to the authorized transferee, or the registered holder, as
the case may be. The Company and the Trustee may deem and treat the person in
whose name this Bond is registered as the absolute owner for the purpose of receiving
payment of or on account of the principal and interest due hereon and for all
other purposes.

    

    This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

    

    IN WITNESS WHEREOF,
the Company has caused this Bond to be executed in its name by the manual or
facsimile signature of an Authorized Executive Officer and attested by the
manual or facsimile signature of another Authorized Executive
Officer.

to be issued in one or more series under and secured by an Open-End Mortgage,
General Mortgage Indenture and Deed of Trust, dated as of June 19, 2008, duly
executed by the Company to The Bank of New York Mellon Trust Company, N.A.
(formerly known as The Bank of New York Trust Company, N.A.), a national banking
association organized and existing under the laws of the United States of
America, as Trustee (the “Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the Fourth Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental

which Open-End Mortgage, General Mortgage Indenture and Deed of Trust and all
indentures supplemental thereto (collectively referred to as the “Indenture”)
reference is hereby made for a description of the property mortgaged and
pledged, the nature and extent of the security, the terms and conditions upon
which such Bonds are, and are to be, issued and secured, and the rights of the
owners of such Bonds and the Trustee in respect of such security.  As
provided in the Indenture, such Bonds may be in various principal sums, are
issuable in series, may mature at different times, may bear interest at
different rates and may otherwise vary as therein provided; and this Bond is one
Bond of a series entitled “First Mortgage Bonds, Guarantee Series E of 2009 due
2029,” created by the Supplemental Indenture, as provided for in the Indenture,
and authorized for issuance in an aggregate principal amount of up to
$6,450,000.

     

    If and when the
principal of any Revenue Bonds is paid, then there is deemed to be paid an equal
principal amount of the Bonds of this series then outstanding; provided,
however, that such payment of the Bonds of this series is deemed to be made only
when and to the extent that notice of such payment of such Revenue Bonds is
given by the Company to the Trustee.

     

    The Bonds of this
series shall be redeemed by the Company in whole at any time prior to maturity
at a redemption price of 100% of the principal amount thereof plus accrued and
unpaid interest to the date of redemption following receipt by the Trustee of
written demand for redemption (a “Redemption
Demand”) from an authorized representative of the Revenue Bond Trustee
under the Revenue Bond Indenture stating that the principal amount of all the
Revenue Bonds then outstanding under the Revenue Bond Indenture has been
declared due and payable pursuant to the provisions of Section 11.02 of the
Revenue Bond Indenture, specifying the date of the accelerated maturity of such
Revenue Bonds and the date or dates from which interest on the Revenue Bonds has
then accrued and is unpaid (specifying the rate or rates of such accrual and the
principal amount of the particular Revenue Bonds to which such rates apply),
stating such declaration of maturity has not been annulled and demanding payment
of the principal amount of the Bonds of this series plus accrued interest
thereon to the date fixed for such redemption. The date fixed for such
redemption shall be set forth in the aforesaid Redemption Demand and shall not
be earlier than the date specified in such Redemption Demand as the date of
accelerated maturity of the Revenue Bonds then outstanding under the Revenue
Bond Indenture and not later than forty-five days after the Trustee’s receipt of
such Redemption Demand unless such forty-fifth day is earlier than such date of
accelerated maturity.  The Revenue Bond Trustee as the sole holder of
the Bonds of this series, and any successor thereto, hereby irrevocably waives
any requirement of notice of such redemption under Section 5.04 of the
Indenture.  Upon receipt of the aforesaid Redemption Demand, the
earliest date from which unpaid interest on the Revenue Bonds has then accrued
(as specified by the Revenue Bond Trustee in the Redemption Demand) shall become

any demand for payment of the principal amount thereof at maturity as a result
of the principal of the Revenue Bonds becoming due and payable on the maturity
date of the Bonds of this series, the earliest date from which unpaid interest
on the Revenue Bonds has then accrued shall become the Initial Interest Accrual
Date with respect to the Bonds of this series, such date, together with each
other different date from which unpaid interest on the Revenue Bonds has then
accrued, to be as stated in a written notice from the Revenue Bond Trustee to
the Trustee, which notice shall also specify the rate or rates of such accrual
and the principal amount of the particular Revenue Bonds to which such rate or
rates apply.  Such redemption shall become null and void for all
purposes under the Indenture (including the fixing of the Initial Interest
Accrual Date with respect to the Bonds of this series) upon receipt by the
Trustee of written notice from the Revenue Bond Trustee of the annulment of the
acceleration of the maturity of the Revenue Bonds then outstanding under the
Revenue Bond Indenture and of the rescission of the aforesaid Redemption Demand
prior to the redemption date specified in the Redemption Demand, and thereupon
no redemption of the Bonds of this series and no payment in respect thereof as
specified in the Redemption Demand, shall be effected or
required.  But no such rescission shall extend to any subsequent
Redemption Demand from the Revenue Bond Trustee or impair any right consequent
on any such subsequent Redemption Demand.

     

    The “Revenue Bond
Interest Rate” shall be the same rate of interest per annum as is borne
by the Revenue Bonds; provided, however, that if there are different rates of
interest borne by the Revenue Bonds, or if interest is required to be paid on
the Revenue Bonds more frequently than on each February 1 or August 1, the
Revenue Bond Interest Rate shall be the rate that results in the total amount of
interest payable on an Interest Payment Date, a redemption date or at maturity,
as the case may be, or at any other time interest on this Bond is due and
payable, to be equal to the total amount of unpaid interest that has accrued on
all then outstanding Revenue Bonds.

     

    The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the

    From and after the
Release Date (as defined in the Revenue Bond Indenture), the Bonds of this
series shall be deemed fully paid, satisfied and discharged and the obligation
of the Company thereunder shall be terminated.  On the Release Date or
promptly following, the Bonds of this series shall be surrendered to and
cancelled by the Trustee.

    

    No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived

payment of or on account of the principal and interest due hereon and for all
other purposes.

    

    This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a

a corporation of the State of Ohio (herein, together with its successors and

“Administrative

dated as of April 3, 2006, among the Company, Barclays Bank PLC, acting through
its New York Branch, as Fronting Bank and Administrative Agent, KeyBank National
Association, as Syndication Agent, and the Banks parties thereto from time to
time (such Reimbursement Agreement, as amended from time to time, hereinafter
the “Reimbursement
Agreement”), or registered assigns, on April 1, 2011, the principal sum
of [_____________________] Dollars or, at any time (if less), such lesser
principal amount as is equal to the sum of (a) the Available Amount of the
Letter of Credit outstanding at such time, plus (b) the aggregate principal
amount of all Tender Advances which are outstanding at such time, plus (c) the
aggregate amount of all other reimbursement obligations of the Company to the
Banks constituting demand loans pursuant to Section 2.04 of the Reimbursement
Agreement which are outstanding at such time, on such date or dates and in such
amounts as set forth in the Reimbursement Agreement for the payment of principal
on such Tender Advances and demand loans, and to pay interest on said principal
amount from the date hereof at such rate or rates per annum on each day as
shall cause the amount of interest payable on the Bonds of this series on an
Interest Payment Date (as hereinafter defined) to equal the amount of
outstanding Obligations (other than Tender Advances or reimbursement obligations
of the Company to the Banks constituting demand loans pursuant to Section 2.04
of the Reimbursement Agreement) payable on such Interest Payment Date; provided,
however,
that such interest rate or rates shall not exceed ten percent (10%) per annum

hereon until the principal hereof shall be paid in full, subject to Section 2.04
of the Fourth Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental
Indenture”),
executed and delivered by the Company to the Trustee (as hereinafter defined),
which provides for certain credits towards payment of principal of, and interest
on, the Bonds of this series.  No payment of principal under such
Tender Advances or demand loans or hereunder shall reduce the stated principal
amount of the Bonds of this series unless, and only to the extent that, the
Reimbursement Agreement shall be terminated concurrently therewith in accordance
with the provisions of Section 2.02(c) of the Reimbursement
Agreement.  Interest shall accrue on the Bonds of this series from the
date of issuance hereof, and the payment thereof shall be credited as provided
in Section 2.04(a) of the Supplemental Indenture unless and until the Trustee
receives the notice contemplated by Section 2.04(b) of the Supplemental
Indenture, whereupon the interest on the Bonds of this series shall become and
remain due and payable until such time as the Trustee receives a further written
notice (including a telecopy or other form of written telecommunication) from an
authorized representative of the Administrative Agent stating that such payments
need not continue.  The interest on each Bond of this series so
payable on any Interest Payment Date shall, subject to the exceptions provided
in Section 3.07 of the Indenture (as hereinafter defined) and to the provisions
of Section 2.04 of the Supplemental Indenture, be paid to the person in whose
name such Bond is registered on the date of such payment.  The
principal of, and the interest on, this Bond shall be payable at the office or
agency of the Company in the City of Cleveland, State of Ohio in any coin or
currency of the United States of America which at the time of payment is legal
tender for the payment of public and private debts.

     

    As used herein,
“Interest
Payment Date” shall mean (i) in the case of Obligations representing
interest payable on Tender Advances or on reimbursement obligations of the
Company to the Banks constituting demand loans pursuant to Section 2.04 of the
Reimbursement Agreement, the date on which any such interest is due under and as
provided in the Reimbursement Agreement, and (ii) in the case of Obligations
other than (x) interest covered by the preceding clause (i) and (y) Tender
Advances or reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement, the
applicable date for the payment of such Obligations under the Reimbursement
Agreement.  As used herein, the terms “Available
Amount,” “Banks,”
“Commitments,”
“Letter of
Credit,” “Obligations,” and “Tender
Advances” shall have the respective meanings set forth in the
Reimbursement Agreement.  The Letter of Credit was issued in favor of
the bond trustee for $56,600,000 aggregate principal amount of Pollution Control
Revenue Refunding Bonds, Series 2006-A (FirstEnergy Generation Corp. Project)
issued by the Beaver County Industrial Development Authority.

     

    This Bond is one of
an issue of Bonds of the Company issued and to be issued in one or more series
under and secured by an Open-End Mortgage, General Mortgage Indenture and Deed
of Trust, dated as of June 19, 2008, duly executed by the Company to The Bank of
New York Mellon Trust Company, N.A. (formerly known as The Bank of New York
Trust Company, N.A.), a national banking association organized and existing
under the laws of the United States of America, as Trustee (the “Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the Supplemental Indenture, to which Open-End Mortgage, General Mortgage
Indenture and Deed of Trust and all indentures supplemental thereto

    property mortgaged
and pledged, the nature and extent of the security, the terms and conditions
upon which such Bonds are, and are to be, issued and secured, and the rights of
the owners of such Bonds and the Trustee in respect of such
security.  As provided in the Indenture, such Bonds may be in various
principal sums, are issuable in series, may mature at different times, may bear
interest at different rates and may otherwise vary as therein provided; and this
Bond is one Bond of a series entitled “First Mortgage Bonds, Collateral Series B
of 2009 due 2011,” created by the Supplemental Indenture, as provided for in the
Indenture, and authorized for issuance in an aggregate principal amount of up to
$57,159,000.

     

    Any payment of
Obligations made by or on behalf of the Company in respect of the Reimbursement
Agreement shall be deemed a payment in respect of this Bond, but such payment
shall not reduce the principal amount of this Bond then in effect unless the sum
of (a) the Available Amount of the Letter of Credit outstanding at such time,
plus (b) the aggregate principal amount of all Tender Advances which are then
outstanding under the Reimbursement Agreement, plus (c) the aggregate amount of
all other reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement which are
outstanding at such time, is irrevocably reduced concurrently with such payment;
provided,
however,
if after a drawing under the Letter of Credit, the Letter of Credit shall have
been reinstated in respect of such drawing prior to the Administrative Agent,
Fronting Bank or Banks having received reimbursement for such drawing from the
Company, the reimbursement of such reinstated amount shall not reduce the
principal amount of this Bond.  In the event that all of the Company's
obligations under the Reimbursement Agreement have been discharged and the
Letter of Credit shall have been cancelled and returned to the Fronting Bank,
this Bond shall be deemed paid in full and the Holder shall surrender this Bond
to the Trustee for cancellation.

     

    The Bonds of this
series shall be redeemed promptly, without notice, by the Company in whole at
100% of the principal amount thereof plus accrued interest to the date of
redemption (the “Redemption
Price”) following receipt by the Trustee of written demand for redemption
(a “Redemption
Demand”)  from an authorized representative of the
Administrative Agent under the Reimbursement Agreement stating that (i) all of
the Obligations under the Reimbursement Agreement have become or have been
declared to be immediately due and payable as a result of the occurrence and
continuance of an “Event of Default” under the Reimbursement Agreement and (ii)
that the Administrative Agent has demanded payment thereof from the Company;
provided that the Bonds
of this series shall be redeemed automatically by the Company, without any
notice to any person, in whole at the Redemption Price, if the Obligations under
the Reimbursement Agreement have become immediately due and payable as a result
of the occurrence of an “Event of Default” under the Reimbursement Agreement
with respect to the Company (but not any subsidiary thereof) under Section
6.01(f) of the Reimbursement Agreement.  Such redemption shall be
effected on the fifth Business Day following receipt by the Trustee of the
Redemption Demand, if such Redemption Demand is required, or the occurrence of
an “Event of Default” under the Reimbursement Agreement with respect to the
Company (but not any subsidiary thereof) under Section 6.01(f) of the
Reimbursement Agreement.  Any payment of the Redemption Price made to
the Administrative Agent shall constitute a payment by the Company in respect of
Obligations under the Reimbursement Agreement.  A Redemption Demand
shall be rescinded and shall be null and void for all purposes of the Indenture
upon receipt by the Trustee, no later than the Business Day prior to the

    date fixed for
redemption, of a written notice from the Administrative Agent withdrawing said
Redemption Demand.

     

     

    The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

     

    No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

     

    This Bond is
nontransferable except to effect transfer to any successor to the Administrative
Agent under the Reimbursement Agreement, but is exchangeable by the registered
holder hereof, in person or by attorney duly authorized, at the Corporate Trust
Office of the Trustee, any such permitted transfer or exchange to be made in the
manner and upon the conditions prescribed in the Indenture, upon the surrender
and cancellation of this Bond and the payment of any applicable taxes and fees
required by law, and upon any such transfer or exchange a new registered Bond or
Bonds of the same series and tenor, will be issued to the authorized transferee,
or the registered holder, as the case may be. The Company and the Trustee may
deem and treat the person in whose name this Bond is registered as the absolute
owner for the purpose of
receiving payment of or on account of the principal and interest due hereon and
for all other purposes.

     

    This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

    FIRSTENERGY GENERATION CORP.,
a corporation of the State of Ohio (herein, together with its successors and
assigns, the “Company”),
for value received promises to pay to [________], as Administrative Agent (the
“Administrative
Agent”) under that certain Letter of Credit and Reimbursement Agreement,
dated as of April 3, 2006, among the Company, Barclays Bank PLC, acting through
its New York Branch, as Fronting Bank and Administrative Agent, KeyBank National
Association, as Syndication Agent, and the Banks parties thereto from time to
time (such Reimbursement Agreement, as amended from time to time, hereinafter
the “Reimbursement
Agreement”), or registered assigns, on April 1, 2011, the principal sum
of [_____________________] Dollars or, at any time (if less), such lesser
principal amount as is equal to the sum of (a) the Available Amount of the
Letter of Credit outstanding at such time, plus (b) the aggregate principal
amount of all Tender Advances which are outstanding at such time, plus (c) the
aggregate amount of all other reimbursement obligations of the Company to the
Banks constituting demand loans pursuant to Section 2.04 of the Reimbursement
Agreement which are outstanding at such time, on such date or dates and in such
amounts as set forth in the Reimbursement Agreement for the payment of principal
on such Tender Advances and demand loans, and to pay interest on said principal
amount from the date hereof at such rate or rates per annum on each day as
shall cause the amount of interest payable on the Bonds of this series on an
Interest Payment Date (as hereinafter defined) to equal the amount of
outstanding Obligations (other than Tender Advances or reimbursement obligations
of the Company to the Banks constituting demand loans pursuant to Section 2.04
of the Reimbursement Agreement) payable on such Interest Payment Date; provided,
however,
that such interest rate or rates shall not exceed ten percent (10%) per annum

      days elapsed). Said interest shall accrue
hereon until the principal hereof shall be paid in full, subject to Section 2.04
of the Fourth Supplemental Indenture dated as of June 15, 2009 (as amended,
supplemented, modified or restated, the “Supplemental
Indenture”),
executed and delivered by the Company to the Trustee (as hereinafter defined),
which provides for certain credits towards payment of principal of, and interest
on, the Bonds of this series.  No payment of principal under such
Tender Advances or demand loans or hereunder shall reduce the stated principal
amount of the Bonds of this series unless, and only to the extent that, the
Reimbursement Agreement shall be terminated concurrently therewith in accordance
with the provisions of Section 2.02(c) of the Reimbursement
Agreement.  Interest shall accrue on the Bonds of this series from the
date of issuance hereof, and the payment thereof shall be credited as provided
in Section 2.04(a) of the Supplemental Indenture unless and until the Trustee
receives the notice contemplated by Section 2.04(b) of the Supplemental
Indenture, whereupon the interest on the Bonds of this series shall become and
remain due and payable until such time as the Trustee receives a further written
notice (including a telecopy or other form of written telecommunication) from an
authorized representative of the Administrative Agent stating that such payments
need not continue.  The interest on each Bond of this series so
payable on any Interest Payment Date shall, subject to the exceptions provided
in Section 3.07 of the Indenture (as hereinafter defined) and to the provisions
of Section 2.04 of the Supplemental Indenture, be paid to the person in whose
name such Bond is registered on the date of such payment.  The
principal of, and the interest on, this Bond shall be payable at the office or
agency of the Company in the City of Cleveland, State of Ohio in any coin or
currency of the United States of America which at the time of payment is legal
tender for the payment of public and private debts.

    

     

    As used herein,
“Interest
Payment Date” shall mean (i) in the case of Obligations representing
interest payable on Tender Advances or on reimbursement obligations of the
Company to the Banks constituting demand loans pursuant to Section 2.04 of the
Reimbursement Agreement, the date on which any such interest is due under and as
provided in the Reimbursement Agreement, and (ii) in the case of Obligations
other than (x) interest covered by the preceding clause (i) and (y) Tender
Advances or reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement, the
applicable date for the payment of such Obligations under the Reimbursement
Agreement.  As used herein, the terms “Available
Amount,” “Banks,”
“Commitments,”
“Letter of
Credit,” “Obligations,” and “Tender
Advances” shall have the respective meanings set forth in the
Reimbursement Agreement.  The Letter of Credit was issued in favor of
the bond trustee for $90,140,000 aggregate principal amount of State of Ohio
Pollution Control Revenue Refunding Bonds, Series 2006-A (FirstEnergy Generation
Corp. Project) issued by the Ohio Water Development Authority.

     

    This Bond is one of
an issue of Bonds of the Company issued and to be issued in one or more series
under and secured by an Open-End Mortgage, General Mortgage Indenture and Deed
of Trust, dated as of June 19, 2008, duly executed by the Company to The Bank of
New York Mellon Trust Company, N.A. (formerly known as The Bank of New York
Trust Company, N.A.), a national banking association organized and existing
under the laws of the United States of America, as Trustee (the “Trustee”),
and indentures supplemental thereto, heretofore or hereafter executed, including
the Supplemental Indenture, to which Open-End Mortgage, General Mortgage
Indenture and Deed of Trust and all indentures supplemental thereto
(collectively referred to as the “Indenture”)
reference is hereby made for a description of the

    property mortgaged
and pledged, the nature and extent of the security, the terms and conditions
upon which such Bonds are, and are to be, issued and secured, and the rights of
the owners of such Bonds and the Trustee in respect of such
security.  As provided in the Indenture, such Bonds may be in various
principal sums, are issuable in series, may mature at different times, may bear
interest at different rates and may otherwise vary as therein provided; and this
Bond is one Bond of a series entitled “First Mortgage Bonds, Collateral Series C
of 2009 due 2011,” created by the Supplemental Indenture, as provided for in the
Indenture, and authorized for issuance in an aggregate principal amount of up to
$91,030,000.

     

    Any payment of
Obligations made by or on behalf of the Company in respect of the Reimbursement
Agreement shall be deemed a payment in respect of this Bond, but such payment
shall not reduce the principal amount of this Bond then in effect unless the sum
of (a) the Available Amount of the Letter of Credit outstanding at such time,
plus (b) the aggregate principal amount of all Tender Advances which are then
outstanding under the Reimbursement Agreement, plus (c) the aggregate amount of
all other reimbursement obligations of the Company to the Banks constituting
demand loans pursuant to Section 2.04 of the Reimbursement Agreement which are
outstanding at such time, is irrevocably reduced concurrently with such payment;
provided,
however,
if after a drawing under the Letter of Credit, the Letter of Credit shall have
been reinstated in respect of such drawing prior to the Administrative Agent,
Fronting Bank or Banks having received reimbursement for such drawing from the
Company, the reimbursement of such reinstated amount shall not reduce the
principal amount of this Bond.  In the event that all of the Company's
obligations under the Reimbursement Agreement have been discharged and the
Letter of Credit shall have been cancelled and returned to the Fronting Bank,
this Bond shall be deemed paid in full and the Holder shall surrender this Bond
to the Trustee for cancellation.

     

    The Bonds of this
series shall be redeemed promptly, without notice, by the Company in whole at
100% of the principal amount thereof plus accrued interest to the date of
redemption (the “Redemption
Price”) following receipt by the Trustee of written demand for redemption
(a “Redemption
Demand”)  from an authorized representative of the
Administrative Agent under the Reimbursement Agreement stating that (i) all of
the Obligations under the Reimbursement Agreement have become or have been
declared to be immediately due and payable as a result of the occurrence and
continuance of an “Event of Default” under the Reimbursement Agreement and (ii)
that the Administrative Agent has demanded payment thereof from the Company;
provided that the Bonds
of this series shall be redeemed automatically by the Company, without any
notice to any person, in whole at the Redemption Price, if the Obligations under
the Reimbursement Agreement have become immediately due and payable as a result
of the occurrence of an “Event of Default” under the Reimbursement Agreement
with respect to the Company (but not any subsidiary thereof) under Section
6.01(f) of the Reimbursement Agreement.  Such redemption shall be
effected on the fifth Business Day following receipt by the Trustee of the
Redemption Demand, if such Redemption Demand is required, or the occurrence of
an “Event of Default” under the Reimbursement Agreement with respect to the
Company (but not any subsidiary thereof) under Section 6.01(f) of the
Reimbursement Agreement.  Any payment of the Redemption Price made to
the Administrative Agent shall constitute a payment by the Company in respect of
Obligations under the Reimbursement Agreement.  A Redemption Demand
shall be rescinded and shall be null and void for all purposes of the Indenture
upon receipt by the Trustee, no later than the Business Day prior to the

    date fixed for
redemption, of a written notice from the Administrative Agent withdrawing said
Redemption Demand.

     

     

    The principal of
this Bond may be declared or may become due before the maturity hereof, on the
conditions, in the manner and at the times set forth in the Indenture, upon the
happening of an Event of Default as therein defined.

     

    No recourse shall be
had for the payment of the principal of or premium, or interest if any, on this
Bond, or any part hereof, or for any claim based hereon or otherwise in respect
hereof, or of the indebtedness represented hereby, or upon any obligation,
covenant or agreement under the Indenture, against any incorporator,
stockholder, officer or director, as such, past, present or future of the
Company or of any predecessor or successor corporation (either directly or
through the Company or a predecessor or successor corporation), whether by
virtue of any Constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability of
incorporators, stockholders, officers and directors being released by the
registered owner hereof by the acceptance of this Bond and being likewise waived
and released by the terms of the Indenture.

     

    This Bond is
nontransferable except to effect transfer to any successor to the Administrative
Agent under the Reimbursement Agreement, but is exchangeable by the registered
holder hereof, in person or by attorney duly authorized, at the Corporate Trust
Office of the Trustee, any such permitted transfer or exchange to be made in the
manner and upon the conditions prescribed in the Indenture, upon the surrender
and cancellation of this Bond and the payment of any applicable taxes and fees
required by law, and upon any such transfer or exchange a new registered Bond or
Bonds of the same series and tenor, will be issued to the authorized transferee,
or the registered holder, as the case may be. The Company and the Trustee may
deem and treat the person in whose name this Bond is registered as the absolute
owner for the purpose of
receiving payment of or on account of the principal and interest due hereon and
for all other purposes.

     

    This Bond shall not
be valid until authenticated by the manual signature of the Trustee, or a
successor Trustee or Authenticating Agent appointed pursuant to the
Indenture.

     

    

    IN WITNESS WHEREOF,
the Company has caused this Bond to be executed in its name by the manual or
facsimile signature of an Authorized Executive Officer and attested by the
manual or facsimile signature of another Authorized Executive
Officer.
