First and Refunding Mortgage Bond,

2.800% Series Due 2050,

Due June 15, 2050

(CONTINUED)

This bond is one of a duly authorized issue of bonds of the Company, unlimited as to amount except as provided in the Mortgage hereinafter mentioned or in any indenture supplemental thereto, and is one of a series of said bonds known as First and Refunding Mortgage Bonds, 2.800% Series due 2050. This bond and all other bonds of said issue are issued and to be issued under and pursuant to and are all secured equally and ratably by an indenture of mortgage and deed of trust dated May 1, 1923, duly executed and delivered by The Counties Gas and Electric Company (to which the Company is successor) to Fidelity Trust Company, as Trustee (to which U.S. Bank National Association, a national banking association organized and existing under the laws of the United States of America, is successor Trustee), as amended, modified or supplemented by certain supplemental indentures from the Company or its predecessors to said successor Trustee or its predecessors, said mortgage, as so amended, modified or supplemented being herein called the Mortgage. Reference is xxxxxx made to the Mortgage for a statement of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of said bonds and of the Trustee in respect of such security, the rights, duties and immunities of the Trustee, and the terms and conditions upon which said bonds are and are to be secured, and the circumstances under which additional bonds may be issued.

As provided in the Mortgage, the bonds secured thereby may be for various principal sums and are issuable in series, which series may mature at different times, may bear interest at different rates, and may otherwise vary. The bonds of this series mature on June 15, 2050, and are issuable only in registered form without coupons in any denomination authorized by the Company.

Any bond or bonds of this series may be exchanged for another bond or bonds of this series in a like aggregate principal amount in authorized denominations, upon presentation at the office of the Trustee in the City of Philadelphia, Pennsylvania, or, at the option of the holder, at the office or agency of the Company in the Borough of Manhattan, The City of New York, all subject to the terms of the Mortgage but without any charge other than a sum sufficient to reimburse the Company for any stamp tax or other governmental charge incident to the exchange. 

The bonds of this series are redeemable at the option of the Company, as a whole or in part, at any time upon notice sent by the Company through the mail, postage prepaid, at least thirty (30) days and not more than forty-five (45) days prior to the date fixed for redemption, to the registered holder of each bond to be redeemed, addressed to such holder at his address appearing upon the registration books. At any time prior to December 15, 2049, the redemption price shall be equal to the greater of (1) 100% of the principal amount of the bonds to be redeemed, plus accrued interest to the redemption date, or (2) as determined by the Quotation

Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the bonds to be redeemed that would be due if such bonds matured on December 15, 2049 but for the redemption (not including any portion of payments of interest accrued as of the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate plus 25 basis points, plus accrued interest to the redemption date. At any time on or after December 15, 2049 the redemption price shall be equal to 100% of the principal amount of the bonds to be redeemed, plus accrued interest to the redemption date. Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the bonds of this series or portions of the bonds of this series called for redemption.

“Adjusted Treasury Rate” means, with respect to any redemption date, the rate per year 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 the redemption date.

“Business Day” means any day that is not a day on which banking institutions in New York City are authorized or required by law or regulation to close.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the bonds (assuming for these purposes that the bonds mature on December 15, 2049) of this series that would be used, 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 this series. 

“Comparable Treasury Price” means, with respect to any redemption date:

•the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations; or

ARTICLE I.

AMENDMENTS OF MORTGAGE

Section 1. Article II of the Ninth Supplemental Indenture to the Mortgage, as heretofore amended, is hereby further amended as follows:

By adding to paragraph (d) of Section 5 and to the first clause of Section 9, the following:

“2.800% Series due 2050”

ARTICLE II.

BONDS OF THE NEW SERIES

Section 1. The bonds of the New Series shall be designated as hereinabove specified for such designation in the recital immediately preceding the form of bonds of the New Series, subject however, to the provisions of Section 2 of Article I of the Mortgage, as amended, and are issuable only as registered bonds without coupons, substantially in the form hereinbefore recited. Subject to the provisions of the Mortgage, the bonds of the New Series shall be issuable without limitation as to the aggregate principal amount thereof.

The bonds of the New Series shall bear interest from the date thereof and shall be dated as of the interest payment date to which interest was paid next preceding the date of issue unless (a) such date of issue is an interest payment date to which interest was paid, in which event such bonds shall be dated as of such interest payment date, or (b) issued prior to the occurrence of the first interest payment date on which interest is to be paid, in which event such bonds shall be dated June 8, 2020. The bonds of the New Series shall mature on June 15, 2050.

The bonds of the New Series shall bear interest (computed on the basis of a 360-day year of twelve 30-day months) at the rate provided in the form of bond hereinbefore recited, payable on June 15 and December 15 of each year, beginning on December 15, 2020, until the Company’s obligation with respect to the payment of principal thereof shall have been discharged. Both principal and interest on bonds of the New Series shall be payable at the office or agency of the Company in the City of Philadelphia, Pennsylvania, or, at the option of the holder, at the office or agency of the Company in the Borough of Manhattan, The City of New York, and shall be payable in such coin or currency of the United States of America as at the time of payment shall constitute legal tender for the payment of public and private debts.

The bonds of the New Series shall be in any denomination authorized by the Company.

Any bond or bonds of the New Series shall be exchangeable for another bond or bonds of the New Series in a like aggregate principal amount. Any such exchange may be made upon presentation at the office of the Trustee in the City of Philadelphia, Pennsylvania, or, at the option of the holder, at the office or agency of the Company in the Borough of Manhattan, The City of New York, without any charge other than a sum sufficient to reimburse the Company for any stamp tax or other governmental charge incident to the exchange.

Section 2. (a) Initially, the bonds of the New Series shall be issued pursuant to a book-entry system administered by The Depository Trust Company (or its successor, referred to herein as the “Depository”) as a global security with no physical distribution of bond certificates to be made except as provided in this Section 2. Any provisions of the Mortgage or the bonds of the New Series requiring physical delivery of bonds shall, with respect to any bonds of the New Series held under the book-entry system, be deemed to be satisfied by a notation on the bond registration books maintained by the Trustee that such bonds are subject to the book-entry system.

(b) So long as the book-entry system is being used, one or more bonds of the New Series in the aggregate principal amount of the bonds of the New Series and registered in the name of the Depository’s nominee (the “Nominee”) will be issued and required to be deposited with the Depository and held in its custody. The book-entry system will be maintained by the Depository and its participants and indirect participants and will evidence beneficial ownership of the bonds of the New Series, with transfers of ownership effected on the records of the Depository, the participants and the indirect participants pursuant to rules and procedures established by the Depository, the participants and the indirect participants. The principal of and any premium on each bond of the New Series shall be payable to the Nominee or any other person appearing on the registration books as the registered holder of such bond or its registered assigns or legal representative at the office of the office or agency of the Company in the City of Philadelphia, Pennsylvania or the Borough of Manhattan, The City of New York. So long as the book-entry system is in effect, the Depository will be recognized as the holder of the bonds of the New Series for all purposes. Transfers of principal, interest and any premium payments or notices to participants and indirect participants will be the responsibility of the Depository, and transfers of principal, interest and any premium payments or notices to beneficial owners will be the responsibility of participants and indirect participants. No other party will be responsible or liable for such transfers of payments or notices or for maintaining, supervising or reviewing such

records maintained by the Depository, the participants or the indirect participants. While the Nominee or the Depository, as the case may be, is the registered owner of the bonds of the New Series, notwithstanding any other provisions set forth herein, payments of principal of, redemption premium, if any, and interest on the bonds of the New Series shall be made to the Nominee or the Depository, as the case may be, by wire transfer in immediately available funds to the account of such holder. Without notice to or consent of the beneficial owners, the Trustee with the consent of the Company and the Depository may agree in writing to make payments of principal, redemption price and interest in a manner different from that set forth herein. In such event, the Trustee shall make payment with respect to the bonds of the New Series in such manner as if set forth herein.

(c) The Company may at any time elect (i) to provide for the replacement of any Depository as the depository for the bonds of the New Series with another qualified depository, or (ii) to discontinue the maintenance of the bonds of the New Series under book-entry system. In such event, the Trustee shall give 30 days’ prior notice of such election to the Depository (or such fewer number of days acceptable to such Depository).

(d) Upon the discontinuance of the maintenance of the bonds of the New Series under a book-entry system, the Company will cause the bonds to be issued directly to the beneficial owners of the bonds of the New Series, or their designees, as further described below. In such event, the Trustee shall make provisions to notify participants and beneficial owners of the bonds of the New Series, by mailing an appropriate notice to the Depository, that bonds of the New Series will be directly issued to beneficial owners of the bonds as of a date set forth in such notice (or such fewer number of days acceptable to such Depository).

(e) In the event that bonds of the New Series are to be issued to beneficial owners of the bonds, or their designees, the Company shall promptly have bonds of the New Series prepared in certificated form registered in the names of the beneficial owners of such bonds shown on the records of the participants provided to the Trustee, as of the date set forth in the notice above. Bonds issued to beneficial owners, or their designees shall be substantially in the form set forth in this Supplemental Indenture, but will not include the provision related to global securities.

(f) If the Depository is replaced as the depository for the bonds of the New Series with another qualified depository, the Company will issue a replacement global security substantially in the form set forth in this Supplemental Indenture.

(g) The Company and the Trustee shall have no liability for the failure of any Depository to perform its obligations to any participant, any indirect participant or any beneficial owner of any bonds of the New Series, and the Company and the Trustee shall not be liable for the failure of any participant, indirect participant or other nominee of any beneficial owner or any bonds of the New Series to perform any obligation that such participant, indirect participant or other nominee may incur to any beneficial owner of the bonds of the New Series.

(h) Notwithstanding any other provision of the Mortgage, on or prior to the date of issuance of the bonds of the New Series, the Trustee shall have executed and delivered to the initial Depository a Letter of Representations governing various matters relating to the Depository and its activities pertaining to the bonds of the New Series. The terms and provisions of such Letter of Representations are incorporated herein by reference and, in the event there shall exist any inconsistency between the substantive provisions of the said Letter of Representations and any provisions of the Mortgage, then, for as long as the initial Depository shall serve as depository with respect to the bonds of the New Series, the terms of the Letter of Representations shall govern.

(i) The Company and the Trustee may rely conclusively upon (i) a certificate of the Depository as to the identity of a participant in the book-entry system; (ii) a certificate of any participant as to the identity of any indirect participant and (iii) a certificate of any participant or any indirect participant as to the identity of, and the respective principal amount of bonds of the New Series owned by, beneficial owners.

Section 3. So long as the bonds of the New Series are held by The Depository Trust Company, such bonds of the New Series shall bear the following legend:

Section 4. So long as any of the bonds of the New Series remain outstanding, the Company shall keep at its office or agency in the Borough of Manhattan, The City of New York, as well as at the office of the Trustee in the City of Philadelphia, Pennsylvania, books for the registry and transfer of outstanding bonds of the New Series, in accordance with the terms and provisions of the bonds of the New Series and the provisions of Section 8 of Article I of said Mortgage.

Section 5. So long as any bonds of the New Series remain outstanding, the Company shall maintain an office or agency in the City of Philadelphia, Pennsylvania, and an office or agency in the Borough of Manhattan, The City of New York, for the payment upon proper demand of the principal of, the interest on, or the redemption price of the outstanding bonds of the New Series, and will from time to time give notice to the Trustee of the location of such office or agency. In case the Company shall fail to maintain for such purpose an office or agency in the City of Philadelphia or shall fail to give such notice of the location thereof, then notices, presentations and demands in respect of the bonds of the New Series may be given or made to or upon the Trustee at its office in the City of Philadelphia and the principal of, the interest on, and

the redemption price of said bonds in such event be payable at said office of the Trustee. All bonds of the New Series when paid shall forthwith be cancelled.

Section 6. The record date for determining the registered holder of this bond entitled to an interest payment shall be fourteen calendar days prior to any interest payment date. Only the registered holder of such bond on such record date shall be entitled to receive such payment, notwithstanding any transfer of such bond upon the registration books subsequent to such record date.

Section 7. The bonds of the New Series shall be issued under and subject to all of the terms and provisions of the Mortgage, of the indentures supplemental thereto referred to in the recitals hereof and of this Supplemental Indenture which may be applicable to such bonds or applicable to all bonds issued under the Mortgage and indentures supplemental thereto.

ARTICLE III.
