[FORM OF REVERSE OF BOND]

DELMARVA POWER & LIGHT COMPANY

FIRST MORTGAGE BOND,

3.50% SERIES DUE NOVEMBER 15, 2023

This bond is one of an issue of bonds of the Company (herein referred to as the “bonds”), not limited in principal amount, issuable in series, which different series may mature at different times, may bear interest at different rates, and may otherwise vary as in the Mortgage hereinafter mentioned, and is one of a series known as its First Mortgage Bonds, 3.50% Series due November 15, 2023 (herein sometimes referred to as “bonds of 3.50% Series”). All bonds of all series and tranches issued and to be issued under and equally and ratably secured (except insofar as any sinking fund, established in accordance with the provisions of the Mortgage hereinafter mentioned, may afford additional security for the bonds of any particular series or tranche) by the Mortgage and Deed of Trust, dated as of October 1, 1943, executed by the Company to THE NEW YORK TRUST COMPANY, as Trustee, to which THE BANK OF NEW YORK MELLON, a New York banking corporation, is successor Trustee (herein, together with any indentures supplemental thereto, including a One Hundred and Twelfth Supplemental Indenture, dated as of November 7, 2013 (the “One Hundred and Twelfth Supplemental Indenture”), called the “Mortgage”), to which reference is made for a description of the property mortgaged and pledged, the nature and extent of the security, the rights and limitations of rights of the holders of the bonds and of the Company in respect thereof, the rights, duties and immunities of the Trustee, and the terms and conditions upon which the bonds are, and are to be, issued and secured. The Mortgage contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than seventy-five percent (75%) in principal amount of all the bonds at the time outstanding (determined as provided in the Mortgage), evidenced as in the Mortgage provided, or in case the rights under the Mortgage of the holder of the bonds of one or more, but less than all, of the series of bonds outstanding shall be affected, then with the consent of the holders of not less than seventy-five percent (75%) in principal amount of the bonds at the time outstanding of the one or more series, taken in the aggregate, affected (determined as provided in the Mortgage), evidenced as in the Mortgage provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Mortgage or modifying in any manner the rights of the holders of the bonds and coupons; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any bonds, or reduce the rate or extend the time of payment of interest thereon, or reduce the principal amount thereof, without the consent of the holder of each bond so affected, or (ii) reduce the aforesaid percentage of bonds, the holders of which are required to consent to any such supplemental indenture without the consent of the holders of all bonds then outstanding. Any such consent by the registered holder of this bond (unless effectively revoked as provided in the Mortgage) shall be conclusive and binding upon such holder and upon all future holders of this bond, irrespective of whether or not any notation of such consent is made upon this bond. No reference herein to the Mortgage and no provision of this bond or of the Mortgage shall alter or impair the obligation of the Company, which is absolute and

unconditional, to pay the principal of, premium, if any, and interest on this bond at the time and place, at the rate and in the coin or currency herein prescribed.

The fully registered bonds of 3.50% Series are issuable in denominations of $1,000 and any integral multiple of $1,000 in excess thereof. At the office or agency to be maintained by the Company in the Borough of Manhattan, The City of New York and in the manner and subject to the limitations provided in the Mortgage, fully registered bonds of such series may be exchanged for a like aggregate principal amount of fully registered bonds of such series of other authorized denominations, and in each case without payment of any service or other similar charge, but the Company may require payment of a sum sufficient to cover any tax or taxes or other governmental charges required to be paid by the Company in relation thereto, as provided in the One Hundred and Twelfth Supplemental Indenture.

The bonds of 3.50% Series shall be redeemable at the option of the Company prior to the express date of the maturity hereof, in whole or in part, at any time. The Company shall give notice of its intent to redeem such bonds of 3.50% Series at least 30 days but no more than 90 days prior to the date fixed for such redemption (the “Redemption Date”). If the Company redeems all or any part of the bonds of 3.50% Series pursuant to the provisions of this paragraph prior to August 15, 2023, it shall pay an amount equal to the greater of:

(i) 100% of the principal amount of the bonds of 3.50% Series being redeemed, and

(ii) the sum of the present values of the remaining scheduled payments of principal of and interest (not including the portion of any scheduled payment of interest which accrued prior to the Redemption Date) on the bonds of 3.50% Series being redeemed, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points,

plus, in each case, accrued interest on those bonds to the Redemption Date (calculated assuming a 360-day year consisting 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 such period). If the Company redeems all or any part of the bonds of 3.50% Series pursuant to the provisions of this paragraph on or after August 15, 2023, it shall pay an amount equal to 100% of the principal amount of the bonds of 3.50% Series being redeemed plus accrued and unpaid interest thereon.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the bonds of 3.50% Series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the bonds of 3.50% Series.

“Comparable Treasury Price” means, with respect to any Redemption Date prior to August 15, 2023, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Independent Investment Banker obtains fewer than four of such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means an investment banking institution of national standing appointed by the Company that is not the Reference Treasury Dealer.

“Reference Treasury Dealer” means a primary United States Treasury securities dealer appointed by the Company.

“Reference Treasury Dealer Quotations” means, with respect to any Redemption Date prior to August 15, 2023, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by the Reference Treasury Dealer at 5:00 p.m. on the third business day preceding such Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date prior to August 15, 2023, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

The Company shall deliver to the Trustee before any Redemption Date for the bonds of 3.50% Series its calculation of the amount applicable to such redemption. The Trustee shall be under no duty to inquire into, may presume the correctness of, and shall be fully protected in acting upon, the Company’s calculation of any Redemption Price of the bonds of 3.50% Series.

In lieu of stating the amount applicable to such redemption, notices of redemption of the bonds of 3.50% Series for a Redemption Date prior to August 15, 2023 shall state substantially the following: “The amount applicable to the bonds of 3.50% Series to be redeemed shall equal the sum of (a) the greater of (i) 100% of the principal amount of such bonds of 3.50% Series, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (not including the portion of any scheduled payment of interest which accrued prior to the Redemption Date) on the bonds of 3.50% Series being redeemed, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the bonds of 3.50% Series) plus 15 basis points, plus, in each case, (b) accrued interest on the principal amount hereof to the Redemption Date.”

If at the time notice of redemption is given the redemption moneys are not on deposit with the Trustee, then the redemption shall be subject to the receipt of such moneys on or before the Redemption Date, and such notice shall be of no effect unless such moneys are received. The Mortgage provides that if the Company shall deposit with the Trustee in trust for the purpose funds sufficient to pay the principal of all of the bonds of any series, or such of the bonds of any series as have been or are to be called for redemption, and premium, if any, thereon, and all interest payable on such bonds to the date on which they become due and payable at maturity or upon redemption or otherwise, and shall comply with the other provisions of the Mortgage in respect thereof, then from the date of such deposit such bonds shall no longer be entitled to any lien or benefit under the Mortgage.

The principal hereof may be declared or may become due prior to the express date of the maturity hereof on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a completed default as in the Mortgage provided.

This bond is transferable as prescribed in the Mortgage by the registered holder hereof in person, or by his or her duly authorized attorney, at the office or agency to be maintained by the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, and thereupon a new fully registered bond or bonds of authorized denominations of the same series and for the same aggregate principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage, and in each case without payment of any service or other similar charge as provided in the One Hundred and Twelfth Supplemental Indenture. The Company and the Trustee, any paying agent and any bond registrar may deem and treat the person in whose name this bond is registered as the absolute owner hereof, whether or not this bond shall be overdue, for the purpose of receiving payment and for all other purposes and neither the Company nor the Trustee nor any paying agent nor any bond registrar shall be affected by any notice to the contrary.

No recourse shall be had for the payment of the principal of, premium, if any, and interest on, this bond, or for any claim based hereon, or otherwise in respect hereof, or based on, or in respect of, the Mortgage, against an incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director, as such, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors, as such, being waived and released by the holder and owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.

ARTICLE I.

DESIGNATION, PROVISIONS, DENOMINATIONS AND ISSUANCE

OF 3.50% SERIES BONDS

SECTION 1. The bonds of 3.50% Series shall be designated as “First Mortgage Bonds, 3.50% Series due November 15, 2023.” The bonds of 3.50% Series shall be issuable from time to time as fully registered bonds in denominations of $1,000 and in any integral multiple of $1,000 in excess thereof. Each of the bonds of 3.50% Series shall be dated the date of issue, and shall bear interest payable from the fifteenth day of May or November, as the case may be, to which interest has been paid preceding the date thereof, unless such date is a May 15 or November 15 on which interest has been paid, in which case it shall bear interest from such date, or unless such date is prior to May 15, 2014, in which case it shall bear interest from November 15, 2013. The interest so payable on any May 15 or November 15 will be paid to the person in whose name this Bond is registered at the close of business on the first calendar day of the month in which the interest payment date occurs. All bonds of 3.50% Series shall be payable on November 15, 2023, in such coin or currency of the United States of America as at the time of payment shall be legal tender for public and private debts, and shall bear interest, payable in like coin and currency, at the rate of three and one-half percent (3.50%) per annum, payable semi-annually on May 15 and November 15 of each year, until maturity, and at the highest rate of interest borne by any of the bonds outstanding under the Original Indenture and any indenture supplemental thereto, from such date of maturity until they shall be paid or payment thereof shall have been duly provided for; provided, however, that interest payable at maturity

will be paid to the person to whom principal is paid. In the event that any interest payment date is a legal holiday or a day on which banking institutions are authorized by law to close, then payment of interest payable on such date may be made on the next succeeding day, not a legal holiday or a day on which banking institutions are authorized by law to close, with the same force and effect as if made on the interest payment date. Interest on the bonds of 3.50% Series shall be computed on the basis of a 360-day year consisting of twelve 30-day months. The principal of, and premium, if any, and interest on, each bond of 3.50% Series shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York.

The bonds of 3.50% Series may be exchanged, for a like aggregate principal amount of fully registered bonds of such series of other authorized denominations. No service or other similar charge shall be made for any exchange, transfer, or registration of the bonds of 3.50% Series, but the Company may require payment of a sum sufficient to cover any tax or taxes or other governmental charges required to be paid by the Company in relation thereto.

The bonds of 3.50% Series shall be redeemable as set forth in the form of bond of the bonds of 3.50% Series set forth in this One Hundred and Twelfth Supplemental Indenture.

This bond is transferable as prescribed in the Mortgage by the registered holder hereof in person, or by his or her duly authorized attorney, at the office or agency to be maintained by the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, and thereupon a new fully registered bond or bonds of authorized denominations of the same series and tranche and for the same aggregate principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage, and in each case without payment of any service or other similar charge as herein provided. The Company and the Trustee, any paying agent and any bond registrar may deem and treat the person in whose name this bond is registered as the absolute owner hereof, whether or not this bond shall be overdue, for the purpose of receiving payment and for all other purposes and neither the Company nor the Trustee nor any paying agent nor any bond registrar shall be affected by any notice to the contrary.

The bonds of 3.50% Series initially shall be represented by one or more securities in registered, global form without interest coupons (a “Global Bond”). The Company initially appoints The Depository Trust Company (“DTC”) to act as depositary with respect to the Global Bonds (together with any successor, the “Depositary”).

Upon the occurrence in respect of the bonds of 3.50% Series of (1) any one or more of the conditions specified in clause (i) of the preceding sentence, the bonds of 3.50% Series shall be exchanged, and (2) any one or more of the conditions specified in clause (ii) or (iii) of the preceding sentence, the bonds of 3.50% Series shall be exchangeable, for bonds registered in the names of, and the transfer of such bond shall be registered to, the beneficial owners of the bonds of the bonds of 3.50% Series, or their designees, as the Depositary shall direct.
