 SUPPLEMENTAL INDENTURE NO. 21 

SUPPLEMENTAL INDENTURE No. 21 dated as of September 1, 2019, made and entered into by and between PPL ELECTRIC
UTILITIES CORPORATION, a corporation of the Commonwealth of Pennsylvania, having its principal corporate offices at Two North Ninth Street, Allentown, Pennsylvania 18101 (hereinafter sometimes called the “Company”), and THE BANK OF NEW
YORK MELLON, a New York banking corporation, having its corporate trust office at 240 Greenwich Street, 7th Floor, New York, New York 10286 (hereinafter sometimes called the “Trustee”),
as Trustee under the Indenture, dated as of August 1, 2001 (hereinafter called the “Original Indenture”), this Supplemental Indenture No. 21 being supplemental thereto. The Original Indenture and any and all indentures and
instruments supplemental thereto are hereinafter sometimes collectively called the “Indenture.” 
 RECITALS OF THE COMPANY

 The Original Indenture was authorized, executed and delivered by the Company to provide for the issuance from time to time of its
Securities (such term and all other capitalized terms used herein without definition having the meanings assigned to them in the Original Indenture), to be issued in one or more series as contemplated therein, and to provide security for the payment
of the principal of and premium, if any, and interest, if any, on such Securities. 
 The Company has heretofore executed and delivered to
the Trustee Supplemental Indentures for the purposes recited therein and for the purpose of creating series of Securities as set forth in Schedule A hereto. 

Pursuant to Article Three of the Original Indenture, the Company wishes to establish a Twenty-Third series of Securities, such series of
Securities to be hereinafter sometimes called “Securities of the Twenty-Third Series.” 
 Pursuant to clauses (d) and (f) of
Section 1301 and clause (g) of Section 301 of the Original Indenture, the Company wishes to modify the period during which notices of redemption may be sent with respect to the Securities of the Twenty-Third Series. 

As contemplated in Section 301 of the Original Indenture, the Company further wishes to establish the designation and certain terms of
the Securities of the Twenty-Third Series. The Company has duly authorized the execution and delivery of this Supplemental Indenture No. 21 to establish the designation and certain terms of the Securities of the Twenty-Third Series and has duly
authorized the issuance of such Securities; and all acts necessary to make this Supplemental Indenture No. 21 a valid agreement of the Company, and to make the Securities of the Twenty-Third Series valid obligations of the Company, have been
performed. 
 NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE NO. 21 WITNESSETH, that, for and in consideration of the premises and of the
purchase of the Securities by the Holders thereof, it is mutually covenanted and agreed, for the equal and proportionate benefit of the Holders of the Securities of the Twenty-Third Series, as follows: 

ARTICLE ONE 

Twenty-Third Series of Securities 

SECTION 101. There is hereby created a series of Securities designated “First Mortgage Bonds, 3.00% Series due 2049,” and the
Securities of such series shall have the terms provided therefor in this Article One of this Supplemental Indenture No. 21, shall be limited in aggregate principal amount (except as contemplated in Section 301(b) of the Original Indenture)
to $400,000,000, and shall have such terms as are hereby established for such Securities of the Twenty-Third Series as contemplated in Section 301 of the Original Indenture. The form or forms and additional terms of the Securities of the
Twenty-Third Series shall be established in an Officer’s Certificate of the Company, as contemplated by Section 201 of the Original Indenture. 












 SECTION 102. Covenants. So long as any Securities of the Twenty-Third Series shall
remain Outstanding, the following shall be an additional covenant of the Company under the Indenture: So long as any Securities of the Twenty-Third Series shall remain Outstanding, the Company shall not cause or permit the Release Date to be
established, as contemplated in Section 1811 of the Original Indenture. 
 SECTION 103. Amendment. With respect to the
Securities of the Twenty-Third Series, notwithstanding the first sentence of Section 504 of the Original Indenture, notice of redemption of the Securities of the Twenty-Third Series shall be given in the manner provided in Section 109 of
the Original Indenture to the Holders of such Securities to be redeemed not less than 10 nor more than 60 days prior to the Redemption Date. 

SECTION 104. Satisfaction and Discharge. The Company hereby agrees that, if the Company shall make any deposit of money and/or Eligible
Obligations with respect to any Securities of the Twenty-Third Series, or any portion of the principal amount thereof, as contemplated by Section 801 of the Indenture, the Company shall not deliver an Officer’s Certificate described in
clause (z) in the first paragraph of said Section 801 unless the Company shall also deliver to the Trustee, together with such Officer’s Certificate, either: 

(a)    an instrument wherein the Company, notwithstanding the satisfaction and discharge of its indebtedness in respect of
such Securities, shall retain the obligation (which shall be absolute and unconditional) irrevocably to deposit with the Trustee or Paying Agent such additional sums of money, if any, or additional Eligible Obligations (meeting the requirements of
Section 801), if any, or any combination thereof, at such time or times, as shall be necessary, together with the money and/or Eligible Obligations theretofore so deposited, to pay when due the principal of and premium, if any, and interest due
and to become due on such Securities or portions thereof, all in accordance with and subject to the provisions of said Section 801; provided, however, that such instrument may state that the obligation of the Company to make additional deposits
as aforesaid shall be subject to the delivery to the Company by the Trustee of a notice asserting the deficiency accompanied by an opinion of an independent public accountant of nationally recognized standing, selected by the Trustee, showing the
calculation thereof (which opinion shall be obtained at the expense of the Company); or 
 (b)    an Opinion of Counsel
to the effect that the Holders of such Securities, or portions of the principal amount thereof, will not recognize income, gain or loss for United States federal income tax purposes as a result of the satisfaction and discharge of the Company’s
indebtedness in respect thereof and will be subject to United States federal income tax on the same amounts, at the same times and in the same manner as if such satisfaction and discharge had not been effected. 

ARTICLE TWO 

Miscellaneous Provisions 

SECTION 201. This Supplemental Indenture No. 21 is a supplement to the Original Indenture, as heretofore amended and supplemented.
As supplemented by this Supplemental Indenture No. 21, the Original Indenture, as heretofore amended and supplemented, is in all respects ratified, approved and confirmed, and the Original Indenture, as heretofore amended and supplemented, and
this Supplemental Indenture No. 21 shall together constitute the Indenture.

 SECTION 202. The recitals contained in this Supplemental Indenture No. 21 shall
be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness and makes no representations as to the validity or sufficiency of this Supplemental Indenture No. 21. 

This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such
