On this 28th day of July, 2020, personally appeared before me, a Notary Public within and for said County in the State aforesaid, Rick Fierro, to me known and known to me to be a Vice President of THE BANK OF NEW YORK MELLON, one of the corporations which executed the foregoing instrument, who acknowledged that he did sign said instrument as such for and on behalf of said corporation and that the same is his free act and deed as such Vice President and the free and corporate act and deed of said corporation; and said Rick Fierro being by me duly sworn, did depose and say: that he resides in _________________; that he is a Vice President of THE BANK OF NEW YORK MELLON, one of the corporations described in and which executed the above instrument; and that he signed his name thereto by like order.

 IN WITNESS WHEREOF I have hereunto set my hand and official seal.

THE DAYTON POWER AND LIGHT COMPANY, a corporation of the State of Ohio (hereinafter called the Company), for value received, hereby promises to pay to ____________ or registered assigns, on July 31, 2040, at the office or agency of the Company in the Borough of Manhattan, The City of New York, the principal sum of [●] DOLLARS (or so much thereof as shall not have been prepaid) on July 31, 2040 (the “Maturity Date”), with interest (a) on the unpaid balance hereof at the rate of 3.20% per annum (the “Coupon Rate”) from the date hereof, payable semiannually, on the 31st day of January and July in each year, commencing with the January 31 or July 31 next succeeding the date hereof, and on the Maturity Date, until the principal hereof shall have become due and payable, and (b) to the extent permitted by law, (x) on any overdue payment of interest and (y) during the continuance of a Default Event (as defined in the Fifty-Third Supplemental Indenture), on such unpaid balance and on any overdue payment of any Make-Whole Amount (as defined in the Fifty-Third Supplemental Indenture) or other premium, at a rate per annum from time to time equal to the greater of (i) the Coupon Rate plus 2% or (ii) 2% over the rate of interest publicly announced by Bank of America, N.A. from time to time in New York, New York as its “base” or “prime” rate (the “Default Rate”) payable semiannually as aforesaid (or, at the option of the registered holder hereof, on demand). The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months and for any period shorter than a full month, on the basis of the actual number of days elapsed. In the event that any date on which principal, interest or Make-Whole Amount is payable on this Bond is not a Business Day (as defined in the Fifty-Third Supplemental Indenture), (a) except as set forth in clause (b), the payment of interest payable on such date will be made on the next succeeding day which is a Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day and (b) the payment of the principal or the Make-Whole Amount payable on such date (including principal due on the Maturity Date) will be made on the next succeeding day which is a Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding day which is a Business Day, in each case, with the same force and effect as if made on the date the payment was originally payable.

This Bond is one of an issue of First Mortgage Bonds of the Company issued in series under and pursuant to and equally secured by an indenture of mortgage and deed of trust dated as of October 1, 1935, executed by the Company to Irving Trust Company, as Trustee (now The Bank

of New York Mellon), as said indenture has been amended and supplemented as hereinafter stated, and is one of a series of said First Mortgage Bonds, which series is designated as the First Mortgage Bonds, 3.20% Series Due 2040, of the Company (hereinafter called the “Bonds of the Series Due 2040”) created and described in a Fifty-Third Supplemental Indenture dated as of July 1, 2020, executed by the Company to The Bank of New York Mellon, as Trustee (the “Fifty-Third Supplemental Indenture”), providing for the sale of the Bonds of the Series Due 2040 in the aggregate principal amount of $140,000,000. Subsequent to the execution and delivery of said indenture of mortgage and deed of trust there have been executed and delivered fifty-three indentures supplemental thereto, including said Fifty-Third Supplemental Indenture, supplementing and amending as therein set forth certain provisions thereof. Said indenture of mortgage and deed of trust and such supplemental indentures collectively are hereinafter sometimes called the “Indenture”.

For a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the Bonds and of the Trustee therein and thereto, the duties and immunities of the Trustee, and the terms and conditions upon which the Bonds are issued and secured, reference is hereby made to the Indenture. The rights and obligations of the Company and of the holders and registered owners of the Bonds of the Series Due 2040 may be modified or amended as provided in the Indenture and in the manner and subject to the limitations set forth in the Indenture; provided, however, that the covenants, conditions, terms and provisions of the Fifty-Third Supplemental Indenture that are limited and applicable only to the Bonds of the Series Due 2040 may be modified or amended at the request of the Company by the holders and registered owners thereof or such lesser percentage thereof as provided in the Fifty-Third Supplemental Indenture; provided, further, that without the consent of the holder or registered owner hereof no such modification or amendment shall extend the maturity of, or reduce the rate of interest on, or otherwise modify the terms of payment of the principal or interest of, this Bond, or any Make-Whole Amount payable with respect hereto, which obligations are absolute and unconditional, nor permit the creation of any lien ranking prior to or equal with the lien of the Indenture on any of the mortgaged property, and any consent by the holder or registered owner of any Bond shall be conclusive and binding upon such registered owner and upon all future holders and registered owners of such Bond, irrespective of whether or not any notation of such consent is made upon such Bond.

Bonds of the Series Due 2040 may be prepaid, prior to maturity, at the election of the Company, as a whole at any time, or in part from time to time, as provided in the Fifty-Third Supplemental Indenture.

Bonds of the Series Due 2040 are subject to a special mandatory redemption, prior to maturity, at the election of one or more Holders as provided in the Fifty-Third Supplemental Indenture.

Upon this Bond becoming due and payable under Section 1 of Article Twelve of the Indenture, whether automatically or by declaration, this Bond will forthwith mature and the entire unpaid principal amount of this Bond, plus (i) all accrued and unpaid interest hereon (including, but not limited to, interest accrued thereon at the Default Rate) and (ii) the Make-Whole Amount determined in respect of the principal amount hereon (to the full extent permitted by applicable

law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges and agrees that each holder of a Bond has the right to maintain its investment in the Bonds free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Bonds are prepaid or are accelerated, or redeemed as a result of a Special Redemption Event (as defined in the Fifty-Third Supplemental Indenture), is intended to provide compensation for the deprivation of such right under such circumstances.

The Trustee shall have no responsibility for any calculation or determination in respect of the establishment of the prepayment or redemption price of this Bond, including any Make-Whole Amount, or any component thereof, and shall be entitled to receive and rely conclusively upon a Treasurer’s Certificate that states the prepayment or redemption price.

The principal hereof may be declared or may become due on the conditions, in the manner and at the time set forth in the Indenture, upon the happening of a completed default as in the Indenture provided.

Subject to the provisions of any legend set forth hereon, this Bond may be exchanged for a like principal amount of other Bonds or transferred as prescribed in the Indenture by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this Bond, and thereupon a new registered Bond or Bonds of the Series Due 2040 without coupons for a like principal amount will be issued in exchange therefor as provided in the Indenture. The Company and the Trustee may deem and treat the person in whose name this Bond is registered as the absolute owner hereof for the purpose of receiving payment of or on account of the principal, Make-Whole Amount, if any, and interest due hereon and for all other purposes.

A service charge will not be made for any registration of transfer or exchange of Bonds of the Series Due 2040, but the Company may require payment of a sum sufficient to cover any stamp tax or other governmental charge payable in connection therewith.

No recourse shall be had for the payment of the principal of, premium, if any, or interest on, this Bond, or under or upon any obligation, covenant or agreement contained in the First Mortgage, against any incorporator, or any past, present, or future subscriber to capital stock, shareholder, officer or director, as such, of the Company or of any predecessor or successor corporation, either directly or through the Company or any predecessor or successor corporation, under any present or future rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, shareholders, 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 shall not become valid or obligatory for any purpose until The Bank of New York Mellon, the Trustee under the Indenture, or its successor thereunder, shall have signed the form of certificate endorsed hereon.

IN WITNESS WHEREOF, The Dayton Power and Light Company has caused this Bond to be executed in its name by the manual or facsimile signature of its President or any Vice President and its corporate seal to be hereunto affixed or a facsimile thereof reproduced hereon and attested by the manual or facsimile signature of its Secretary or an Assistant Secretary.
