signature guaranteed by an Eligible Guarantor Institution, and thereupon one or more new Series B Environmental Control Bonds of any Authorized Initial Denominations and in the same aggregate
initial principal amount will be issued to the designated transferee or transferees. No service charge will be charged for any registration of transfer or exchange of this Series B Environmental Control Bond, but the transferor may be required to
pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange. 
 Each Series B Environmental Control Bondholder, by acceptance of a Series B Environmental Control Bond, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the
obligations of the Issuer or the Indenture Trustee on the Series B Environmental Control Bonds or under the Indenture or any certificate or other writing delivered in connection herewith or therewith, against (i) any owner of a beneficial
interest in the Issuer or (ii) any partner, owner, beneficiary, agent, officer, director or employee of the Indenture Trustee, any holder of a beneficial interest in the Issuer or the Indenture Trustee or of any successor or assign of the
Indenture Trustee, except as any such Person may have expressly agreed (it being understood that all of the Indenture Trustee’s obligations are in its individual capacity). 
 Prior to the due presentment for registration of transfer of this Series B Environmental Control Bond, the Issuer, the Indenture Trustee and
any agent of the Issuer or the Indenture Trustee may treat the Person in whose name this Series B Environmental Control Bond is registered (as of the day of determination) as the owner hereof for the purpose of receiving payments of principal of and
premium, if any, and interest on this Series B Environmental Control Bond and for all other purposes whatsoever, whether or not this Series B Environmental Control Bond be overdue, and neither the Issuer, the Indenture Trustee nor any such agent
shall be affected by notice to the contrary. 
 The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Environmental Control Bonds under the Indenture at any time by the Issuer with the consent of the Holders of Environmental
Control Bonds representing a majority of the Outstanding Amount of all Environmental Control Bonds at the time Outstanding of each Series or Tranche to be affected. The Indenture also contains provisions permitting the Holders of Environmental
Control Bonds representing specified percentages of the Outstanding Amount of the Environmental Control Bonds of all Series, on behalf of the Holders of all the Environmental Control Bonds, to waive compliance by the Issuer with certain provisions
of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Series B Environmental Control Bond (or any one of more Predecessor Environmental Control Bonds) shall be
conclusive and binding upon such Holder and upon all future Holders of this Series B Environmental Control Bond and of any Series B Environmental Control Bond issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof
whether or not notation of such consent or waiver is made upon this Series B Environmental Control Bond. The Indenture also permits the Indenture Trustee to amend or waive certain terms and conditions set forth in the Indenture without the consent
of Holders of the Environmental Control Bonds issued thereunder. 
  

 A-7 

 The term “Issuer” as used in this Series B Environmental Control Bond includes any
successor to the Issuer under the Indenture. 
 The Issuer is permitted by the Indenture, under certain circumstances, to merge
or consolidate, subject to the rights of the Indenture Trustee and the Holders of Environmental Control Bonds under the Indenture. 
 This Series B Environmental Control Bond is an Environmental Control Bond as such term is defined in the Statute. Principal and interest due and payable on this Environmental Control Bond are payable from and secured primarily by
environmental control property authorized by an order issued by the Public Service Commission of the State of West Virginia pursuant to the Statute. Environmental control property includes the right to impose, charge, collect and receive certain
non-bypassable charges (defined in the Statute as “environmental control charges”) to be included in electric utility bills of all electric service retail customers of Monongahela Power Company, a West Virginia electric utility doing
business as Allegheny Power. 
 The Statute provides that the State of West Virginia pledges to and agrees with the
Environmental Control Bondholders that the State of West Virginia will not take or permit any action that impairs the value of the Environmental Control Property or, except as allowed under subsection (e) of W.Va Code §24-2-4e, reduce,
alter or impair Environmental Control Charges that are imposed, collected and remitted for the benefit of the Environmental Control Bondholders until any principal, interest and premium, if any, in respect of the Environmental Control Bonds, all
financing costs and all amounts to be paid to any assignee or financing party under an ancillary agreement are paid or performed in full. 
 The Series B Environmental Control Bonds are issuable only in registered form in Authorized Initial Denominations as provided in the Indenture and the Supplement, subject to certain limitations therein
set forth. 
 This Series B Environmental Control Bond, the Indenture and the Supplement shall be construed in accordance with
the laws of the State of New York, without reference to its conflict of law provisions, and the obligations, rights and remedies of the parties hereunder and thereunder shall be determined in accordance with such laws. 
 No reference herein to the Indenture and no provision of this Series B Environmental Control Bond or of the Indenture shall alter or impair
the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Series B Environmental Control Bond at the times, place, and rate, and in the coin or currency herein prescribed.
