Introductory. PPL Electric Utilities Corporation, a Pennsylvania corporation (“Company”), proposes to issue and sell, and the several Underwriters named in Section 3 hereof (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), propose, severally and not jointly, to purchase, upon the terms and conditions set forth herein, $500,000,000 aggregate principal amount of the Company’s First Mortgage Bonds, 5.55% Series due 2055 (the “Bonds”) to be issued under an Indenture, dated as of August 1, 2001, between the Company and The Bank of New York Mellon, as trustee thereunder (the “Trustee”), as previously amended and supplemented and as to be further amended and supplemented by Supplemental Indenture No. 26 thereto relating to the Bonds (the “Supplemental Indenture”), dated as of August 1, 2025 (such Indenture, as so supplemented, the “Indenture”). The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement (No. 333-277140-03) on Form S-3, including the related preliminary prospectus or prospectus, which registration statement became effective upon filing under Rule 462(e) (“Rule 462(e)”) of the rules and regulations of the Commission (the “Securities Act Regulations”) under the Securities Act of 1933, as amended (the

2 “Securities Act”). Such registration statement covers the registration of the Bonds under the Securities Act. Promptly after the date of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430B (“Rule 430B”) of the Securities Act Regulations and paragraph (b) of Rule 424 (“Rule 424(b)”) of the Securities Act Regulations. Any information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B is referred to as “Rule 430B Information.” Each prospectus used in connection with the offering of the Bonds that omitted Rule 430B Information (other than a “free writing prospectus” as defined in Rule 405 of the Securities Act Regulations (“Rule 405”) that has not been approved in writing by the Company and the Representatives), including any related prospectus supplement and the documents incorporated by reference therein pursuant to Item 12 of Form S-3, is herein called a “preliminary prospectus.” Such registration statement, at any given time, including the amendments or supplements thereto to such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act at such time and the documents otherwise deemed to be a part thereof or included therein by the Securities Act Regulations, is herein called the “Registration Statement.” The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.” The final prospectus in the form first furnished to the Underwriters for use in connection with the offering of the Bonds, including the related prospectus supplement and the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act as of the date hereof, is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in or otherwise deemed by the Securities Act Regulations to be a part of or included in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) which is incorporated by reference in or otherwise deemed by the Securities Act Regulations to be a part of or included in the Registration Statement, such preliminary prospectus or the Prospectus, as the case may be. 2. Representations and Warranties. The Company represents and warrants to each Underwriter as of the date hereof, as of the Applicable Time referred to in Section 2(b) hereof and as of the Closing Date referred to in Section 5 hereof, and agrees with each Underwriter as follows: (a) (A) At the time of filing the Original Registration Statement, (B) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3)

3 of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), (C) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the Securities Act Regulations) made any offer relating to the Bonds in reliance on the exemption of Rule 163 of the Securities Act Regulations (“Rule 163”) or made a bona fide offer (within the meaning of Rule 164(h)(2) of the Securities Act Regulations) and (D) at the date hereof, the Company was and is eligible to register and issue the Bonds as a “well-known seasoned issuer” as defined in Rule 405, including not having been and not being an “ineligible issuer” as defined in Rule 405. The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405, and the Bonds, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on a Rule 405 “automatic shelf registration statement.” The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) of the Securities Act Regulations objecting to the use of the automatic shelf registration statement form; (b) The Original Registration Statement became effective upon filing under Rule 462(e) of the Securities Act Regulations on February 16, 2024, and any post-effective amendment thereto also became effective upon filing under Rule 462(e). No stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with. Any offer that is a written communication relating to the Bonds made prior to the filing of the Original Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c) of the Securities Act Regulations) has been filed with the Commission in accordance with the exemption provided by Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the Securities Act provided by Rule 163. At the respective times the Original Registration Statement and each amendment thereto became effective, at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) of the Securities Act Regulations and at the Closing Date, the Registration Statement complied and will comply in all material respects with the requirements of the Securities Act and the Securities Act Regulations and the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and the rules and regulations thereunder, and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Neither the Prospectus nor any amendments or supplements thereto, at the time the Prospectus or any such amendment or supplement was issued and at the Closing Date, included or will include an untrue statement of a material fact or omitted or will omit

4 to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Each preliminary prospectus (including the prospectus or prospectuses filed as part of the Original Registration Statement or any amendment thereto) complied when so filed and each Prospectus will comply when so filed in all material respects with the Securities Act Regulations and each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. As of the Applicable Time (as defined below), neither (x) the Issuer General Use Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time (including, but not limited to, the Final Term Sheet prepared and filed pursuant to Section 6(b)), and the Statutory Prospectus (as defined below), considered together (collectively, the “General Disclosure Package”), nor (y) any individual Issuer Limited Use Free Writing Prospectus (as defined below), when considered together with the General Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As of the time of the filing of the Final Term Sheet, the General Disclosure Package will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As used in this subsection and elsewhere in this Agreement: “Applicable Time” means 2:10 p.m., New York City time, on August 6, 2025 or such other time as agreed by the Company and the Representatives. “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 of the Securities Act Regulations (“Rule 433”), relating to the Bonds that (i) is required to be filed with the Commission by the Company, (ii) is a “road show that is a written communication” within the meaning of Rule 433(d)(8)(i), whether or not required to be filed with the Commission or (iii) is exempt from filing pursuant to Rule 433(d)(5)(i) because it contains a description of the Bonds or of the offering that does not reflect the final terms, in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g). “Issuer General Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule A hereto. “Issuer Limited Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is not an Issuer General Use Free Writing Prospectus.

5 “Permitted Free Writing Prospectus” means any free writing prospectus consented to in writing by the Company and the Representatives.

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Bonds or until any earlier date that the Company notified or notifies the Representatives as described in Section 6(g), did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified. The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus made in reliance upon and in conformity with written information furnished to the Company as set forth in Schedule B hereto by any Underwriter through the Representatives expressly for use therein or to any statements in or omissions from the Statement of Eligibility of the Trustee under the Indenture.

13 (e) To use its best efforts to qualify the Bonds and to assist in the qualification of the Bonds by you or on your behalf for offer and sale under the securities or “blue sky” laws of such jurisdictions as you may designate, to continue such qualification in effect so long as required for the distribution of the Bonds and to reimburse you for any expenses (including filing fees and fees and disbursements of counsel) paid by you or on your behalf to qualify the Bonds for offer and sale, to continue such qualification, to determine its eligibility for investment and to print any preliminary or supplemental “blue sky” survey or legal investment memorandum relating thereto; provided that the Company shall not be required to qualify as a foreign corporation in any State, to consent to service of process in any State other than with respect to claims arising out of the offering or sale of the Bonds, or to meet any other requirement in connection with this paragraph (e) deemed by the Company to be unduly burdensome; (f) To promptly deliver to you a true and correct copy of the Registration Statement as originally filed and of all amendments thereto heretofore or hereafter filed, including conformed copies of all exhibits except those incorporated by reference, and such number of conformed copies of the Registration Statement (but excluding the exhibits), each related preliminary prospectus, the Prospectus, and any amendments and supplements thereto, as you may reasonably request; (g) If at any time prior to the completion of the sale of the Bonds by the Underwriters (as determined by the Representatives), any event occurs as a result of which the Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary to amend or supplement the Prospectus to comply with applicable law, the Company promptly (i) will notify the Representatives of any such event; (ii) subject to the requirements of paragraph (b) of this Section 6, will prepare an amendment or supplement that will correct such statement or omission or effect such compliance; and (iii) will supply any supplemented or amended Prospectus to the several Underwriters without charge in such quantities as they may reasonably request; provided that the expense of preparing and filing any such amendment or supplement to the Prospectus (x) that is necessary in connection with such a delivery of a supplemented or amended Prospectus more than nine months after the date of this Agreement or (y) that relates solely to the activities of any Underwriter shall be borne by the Underwriter or Underwriters or the dealer or dealers requiring the same; and provided further that you shall, upon inquiry by the Company, advise the Company whether or not any Underwriter or dealer which shall have been selected by you retains any unsold Bonds and, for the purposes of this subsection (g), the Company shall be entitled to assume that the distribution of the Bonds has been completed when they are advised by you that no such Underwriter or dealer retains any Bonds. If at any time following issuance of an Issuer Free Writing Prospectus, there occurs an event or development as a result of which such Issuer Free Writing Prospectus would conflict with the information contained in the Registration Statement (or any other registration statement related to the Bonds) or the Statutory Prospectus or any preliminary prospectus would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the

14 Representatives and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. (h) As soon as practicable, to make generally available to its security holders an earnings statement covering a period of at least twelve months beginning after the “effective date of the registration statement” within the meaning of Rule 158 under the Securities Act which will satisfy the provisions of Section 11(a) of the Securities Act; (i) To pay or bear (i) all expenses in connection with the matters herein required to be performed by the Company, including all expenses (except as provided in Section 6(g) above) in connection with the preparation and filing of the Registration Statement, the General Disclosure Package and the Prospectus, and any amendment or supplement thereto, and the furnishing of copies thereof to the Underwriters, and all audits, statements or reports in connection therewith, and all expenses in connection with the issue and delivery of the Bonds to the Underwriters at the place designated in Section 5 hereof, any fees and expenses relating to the eligibility and issuance of the Bonds in book-entry form and the cost of obtaining CUSIP or other identification numbers for the Bonds, all federal and state taxes (if any) payable (not including any transfer taxes) upon the original issue of the Bonds; (ii) all expenses in connection with the printing, reproduction and delivery of this Agreement and the printing, reproduction and delivery of any preliminary prospectus and each Prospectus, and (except as provided in Section 6(g) above) any amendment or supplement thereto, to the Underwriters; (iii) any and all fees payable in connection with the rating of the Bonds; (iv) all costs and expenses relating to the creation, filing or perfection of the security interests under the Indenture; and (v) the reasonable fees and expenses of the Trustee, including the fees and disbursements of counsel for the Trustee, in connection with the Indenture and the Bonds; (j) During the period from the date of this Agreement through the Closing Date, the Company shall not, without the Representatives’ prior written consent, directly or indirectly, sell, offer to sell, grant any option for the sale of, or otherwise dispose of, any Bonds, any security convertible into or exchangeable into or exercisable for Bonds or any debt securities substantially similar to the Bonds (except for the Bonds issued pursuant to this Agreement); and (k) The Company represents and agrees that, unless it obtains the prior consent of the Representatives (such consent not to be unreasonably withheld), it has not made and will not make any offer relating to the Bonds that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405 of the Securities Act Regulations, required to be filed with the Commission. The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping in accordance with the Securities Act Regulations.

Eric Marr, Esq., Assistant General Counsel, or such other counsel for the Company as may be acceptable to you, an opinion in form and substance satisfactory to you, dated the Closing Date and addressed to you, as Representatives of the Underwriters, substantially to the effect that: (i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the Commonwealth of Pennsylvania, with corporate power and authority to own its properties and conduct its business as described in the General Disclosure Package and the Prospectus; (ii) The Bonds have been duly authorized, executed and delivered by the Company and, assuming due authentication and delivery by the Trustee in the manner provided for in the Indenture and delivery against payment therefor, are valid and legally binding obligations of the Company entitled to the benefits and security of the Indenture, enforceable against the Company in accordance with their terms (except to the extent limited by the Enforceability Exceptions); (iii) The Indenture has been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery by the

17 Trustee, constitutes a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms (except to the extent limited by the Enforceability Exceptions); no authorization, vote, consent or action by the holders of any of the outstanding shares of capital stock of the Company is necessary with respect to the execution and delivery by the Company of the Supplemental Indenture; (iv) (1) The Company has good and sufficient title to all the real property and personal property described in the Indenture as owned by it and as subject to the lien thereof, subject only to Permitted Liens and other Liens that are not prohibited by the Indenture and that, in the judgment of such counsel, do not materially impair the value to the Company of the Mortgaged Property taken as a whole; (2) the Indenture constitutes a valid first mortgage lien that such instrument purports to create upon said properties, subject only to Permitted Liens and other Liens referred to in clause (1), which properties include substantially all of the physical properties of the Company (except such property as may have been duly released from the lien thereof and such property as may not be subjected to the lien thereof under the laws of the Commonwealth of Pennsylvania without the delivery thereof to the Trustee, and certain other classes of property expressly excepted in the Indenture); and (3) all physical properties (other than those of the character not subject to the lien of the Indenture as aforesaid) acquired by the Company after the respective dates of the Indenture and the Supplement Indenture have become or will, upon such acquisition, become subject to the lien thereof, subject, however, to (a) Permitted Liens and other Liens referred to in clause (1), (b) possible limitations arising out of laws relating to preferential transfers of property during certain periods prior to commencement of bankruptcy, insolvency or similar proceedings and to limitations on liens on property acquired by a debtor after the commencement of any such proceedings, and possible claims and taxes of the federal government and (c) other Liens on property at the time such property becomes subject to the Lien of the Indenture pursuant to the “springing lien” provisions in the Granting Clauses of the Indenture, which Liens are not prohibited by the Indenture, and except as otherwise provided in Article Twelve of the Indenture; (v) The Indenture (other than the Supplemental Indenture) has been duly filed and recorded in all jurisdictions in which it is necessary for such instruments to be filed and recorded in order to constitute a lien of record on the property subject thereto and UCC financing statements relating to the Mortgaged Property have been filed with the Pennsylvania Department of State, and no further recordation, registration or filing of the Indenture or instrument of further assurance is necessary in the Commonwealth of Pennsylvania to make effective the security interest intended to be created by the Indenture; (vi) The descriptions in the Registration Statement, the General Disclosure Package and the Prospectus of statutes, legal and governmental proceedings and contracts and other documents are accurate and fairly present the information required to be shown; and (1) such counsel does not know of any legal

CS. § 1903), as amended, and such registration remains in effect, and all requisite action of public boards or bodies (other than in connection or in compliance with the provisions of the securities or “blue sky” laws of any jurisdiction, as to which such counsel need not express an opinion) as may be legally required with respect to all or any of such matters or related thereto has been taken and remains in effect; (x) Except as described in the Registration Statement, the General Disclosure Package and the Prospectus, the Company holds all franchises,

19 certificates of public convenience, licenses and permits necessary to carry on the utility business in which it is engaged; and (xi) All taxes payable to any State or subdivision thereof in connection with the execution, delivery and recordation of the Indenture and the execution, authentication, issuance and delivery of the Bonds have been paid. In rendering such opinion, such counsel may rely as to matters governed by New York law upon the opinion of Troutman Pepper Locke LLP referred to in Section 7(g) of this Agreement. (g) You shall have received from Troutman Pepper Locke LLP, special counsel to the Company, an opinion and disclosure letter in form and substance satisfactory to you, dated the Closing Date and addressed to you, as Representatives of the Underwriters, substantially to the effect that: (i) The Bonds have been duly authorized, executed and delivered by the Company and, assuming due authentication and delivery by the Trustee in the manner provided for in the Indenture and delivery against payment therefor, are valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms (except to the extent limited by the Enforceability Exceptions) and are entitled to the benefits and security of the Indenture; (ii) The Indenture has been duly authorized, executed and delivered by the Company, has been qualified under the Trust Indenture Act and, assuming due authorization, execution and delivery by the Trustee, constitutes a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms (except to the extent limited by the Enforceability Exceptions); (iii) This Agreement has been duly authorized, executed and delivered by the Company; (iv) (1) The Registration Statement has become effective under the Securities Act, and any preliminary prospectus included in the General Disclosure Package at the Applicable Time and the Prospectus were filed with the Commission pursuant to the subparagraph of Rule 424(b) specified in such opinion on the date or dates specified therein, and the Issuer General Use Free Writing Prospectus described in Schedule A attached hereto was filed with the Commission pursuant to Rule 433 on the date specified in such opinion; (2) to the knowledge of such counsel based solely upon a review of the page entitled “Stop Orders” on the Commission’s website, as of the date of such review, no stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued and no proceedings for that purpose have been instituted under the Securities Act; (v) (1) The Registration Statement, as of its effective date, the Prospectus, as of the date of this Agreement, and any amendment or supplement

20 thereto, as of its date, appeared on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and rules and regulations of the Commission thereunder, and the documents incorporated by reference therein pursuant to Item 12 of Form S-3 (the “Incorporated Documents”), as originally filed pursuant to the Exchange Act, appeared on their face to be appropriately responsive in all material respects to the requirements of the Exchange Act and the rules and regulations of the Commission thereunder; and (2) no facts have come to the attention of such counsel that cause such counsel to believe either that the Registration Statement, as of its effective date, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading; the General Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; or that the Prospectus, as supplemented, as of the date of this Agreement and as it shall have been amended or supplemented, as of the Closing Date, contained or contains any untrue statement of a material fact or omits or omitted to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; it being understood that such counsel need express no opinion as to the financial statements and other financial or statistical data, or management’s assessment of the effectiveness of the Company’s internal controls, contained or incorporated by reference in or omitted from the Registration Statement, the General Disclosure Package or the Prospectus, or the Trustee’s statement on eligibility on Form T-1; (vi) No consent, approval, authorization or other order of any public board or body of the United States or the State of New York (except for the registration of the Bonds under the Securities Act and the qualification of the Indenture under the Trust Indenture Act and other than in connection or compliance with the provisions of the securities or “blue sky” laws of any jurisdiction, as to which such counsel need express no opinion) is legally required for the authorization of the issuance of the Bonds in the manner contemplated herein and in the General Disclosure Package and the Prospectus; (vii) The statements in the General Disclosure Package and the Prospectus under the caption “Material U.S. Federal Income Tax Consequences”, to the extent such statements purport to constitute summaries of certain provisions of United States federal income tax law or legal conclusions with respect thereto, subject to the assumptions, qualifications and limitations therein, are accurate in all material respects; and (viii) The statements in the General Disclosure Package and the Prospectus under the caption “Description of the Bonds”, insofar as they purport to constitute summaries of certain terms of the Indenture and the Bonds, constitute accurate summaries of such terms in all material respects; and

21 (ix) The Company is not an “investment company” as such term is defined in the Investment Company Act of 1940, as amended. In rendering such opinion, Troutman Pepper Locke LLP may rely as to matters governed by Pennsylvania law upon the opinion of W. Eric Marr, Esq. or such other counsel referred to in Section 7(f).

Eric Marr, Esq. or such other counsel referred to above; and (i) You shall have received from the Company a copy of the rating letters from S&P Global Ratings, a division of S&P Global Inc., or Moody’s Investors Service, Inc. assigning ratings on the Bonds not lower than those included in the General Disclosure Package or other evidence reasonably satisfactory to the Representatives of such ratings. The Company will furnish you as promptly as practicable after the Closing Date with such conformed copies of such opinions, certificates, letters and documents as you may reasonably request. In case any such condition shall not have been satisfied, this Agreement may be terminated by you upon notice in writing or by telegram to the Company without liability or obligation on the part of the Company or any Underwriter, except as provided in Sections 6(e), 6(i), 9, 11 and 14 hereof. 8. Conditions of Company’s Obligations. The obligations of the Company to sell and deliver the Bonds on the Closing Date are subject to the following conditions: (a) At the Closing Date, no stop order suspending the effectiveness of the Registration Statement shall be in effect or proceeding therefor shall have been instituted or, to the knowledge of the Company, shall be contemplated. (b) At or before the Closing Date, the Pennsylvania Public Utility Commission and any other regulatory authority whose consent or approval shall be required for the issue and the sale of the Bonds by the Company as herein provided shall have taken all requisite action, or all requisite action shall be deemed in fact and law to have been taken, to authorize such issue and sale on the terms set forth in the Prospectus. If any such conditions shall not have been satisfied, then the Company shall be entitled, by notice in writing or by telegram to you, to terminate this Agreement without any liability or obligation on the part of the Company or any Underwriter, except as provided in Sections 6(e), 6(i), 9, 11 and 14 hereof.

22 9. Indemnification and Contribution. (a) The Company agrees that it will indemnify and hold harmless each Underwriter and the officers, directors, partners, members, employees, agents and affiliates of each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act (each “an indemnified party”), against any loss, expense, claim, damage or liability to which, jointly or severally, such Underwriter, indemnified party or such controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, expense, claim, damage or liability (or actions in respect thereof) arises out of or is based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Statutory Prospectus, any Issuer Free Writing Prospectus or the Prospectus, or any amendment or supplement to any thereof, or arises out of or is based upon the omission or alleged omission to state therein any material fact required to be stated therein or necessary to make the statements therein not misleading and, except as hereinafter in this Section 9 provided, the Company agrees to reimburse each indemnified party for any reasonable legal or other expenses as incurred by such indemnified party in connection with investigating or defending any such loss, expense, claim, damage or liability; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, expense, claim, damage or liability arises out of or is based on an untrue statement or alleged untrue statement or omission or alleged omission made in any such document in reliance upon, and in conformity with, written information furnished to the Company as set forth in Schedule B hereto by or through you on behalf of any Underwriter expressly for use in any such document or arises out of, or is based on, statements or omissions from the part of the Registration Statement which shall constitute the Statement of Eligibility under the Trust Indenture Act of the Trustee under the Indenture. (b) Each Underwriter, severally and not jointly, agrees that it will indemnify and hold harmless the Company and its officers and directors, and each of them, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, against any loss, expense, claim, damage or liability to which it or they may become subject, under the Securities Act or otherwise, insofar as such loss, expense, claim, damage or liability (or actions in respect thereof) arises out of or is based on any untrue statement or alleged untrue statement of any material fact contained in the Statutory Prospectus, any Issuer Free Writing Prospectus or the Prospectus, or any amendment or supplement to any thereof, or arises out of or is based upon the omission or alleged omission to state therein any material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, and only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any such documents in reliance upon, and in conformity with, written information furnished to the Company as set forth in Schedule B hereto by or through you on behalf of such Underwriter expressly for use in any such document; and, except as hereinafter in this Section 9 provided, each Underwriter, severally and not jointly, agrees to reimburse the Company and its officers and directors, and each of them, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, for any reasonable legal or other expenses incurred by it or them in connection with investigating or defending any such loss, expense, claim, damage or liability.

23 (c) Upon receipt of notice of the commencement of any action against an indemnified party, the indemnified party shall, with reasonable promptness, if a claim in respect thereof is to be made against an indemnifying party under its agreement contained in this Section 9, notify such indemnifying party in writing of the commencement thereof; but the omission so to notify an indemnifying party shall not relieve it from any liability which it may have to the indemnified party otherwise than under subsection (a) or (b) of this Section 9. In the case of any such notice to an indemnifying party, the indemnifying party shall be entitled to participate at its own expense in the defense, or if it so elects, to assume the defense, of any such action, but, if it elects to assume the defense, such defense shall be conducted by counsel chosen by it and satisfactory to the indemnified party and to any other indemnifying party that is a defendant in the suit. In the event that any indemnifying party elects to assume the defense of any such action and retain such counsel, the indemnified party shall bear the fees and expenses of any additional counsel retained by it unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and the representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them; provided, however, that in no event shall the indemnifying party be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from its own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall be liable in the event of any settlement of any such action effected without its consent. Each indemnified party agrees promptly to notify each indemnifying party of the commencement of any litigation or proceedings against it in connection with the issue and sale of the Bonds. (d) If any Underwriter or person entitled to indemnification by the terms of subsection (a) of this Section 9 shall have given notice to the Company of a claim in respect thereof pursuant to subsection (c) of this Section 9, and if such claim for indemnification is thereafter held by a court to be unavailable for any reason other than by reason of the terms of this Section 9 or if such claim is unavailable under controlling precedent, such Underwriter or person shall be entitled to contribution from the Company for liabilities and expenses, except to the extent that contribution is not permitted under Section 11(f) of the Securities Act. In determining the amount of contribution to which such Underwriter or person is entitled, there shall be considered the relative benefits received by such Underwriter or person and the Company from the offering of the Bonds that were the subject of the claim for indemnification (taking into account the portion of the proceeds of the offering realized by each), the Underwriter or person’s relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and any other equitable considerations appropriate under the circumstances. The Company and the Underwriters agree that it would not be equitable if the amount of such contribution were determined by

24 pro rata or per capita allocation (even if the Underwriters were treated as one entity for such purpose). (e) No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 9 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party and all liability arising out of such litigation, investigation, proceeding or claim, and (ii) does not include a statement as to or an admission of fault, culpability or the failure to act by or on behalf of any indemnified party. (f) The indemnity and contribution provided for in this Section 9 and the representations and warranties of the Company and the several Underwriters set forth in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or the Company or their respective directors or officers, (ii) the acceptance of any Bonds and payment therefor under this Agreement, and (iii) any termination of this Agreement. 10. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Bonds hereunder, the non-defaulting Underwriters may make arrangements satisfactory to the Company for the purchase of such Bonds by other persons, including any of the non-defaulting Underwriters, but if no such arrangements are made by the Closing Date, the other Underwriters shall be obligated, severally in the proportion which their respective commitments hereunder bear to the total commitment of the non-defaulting Underwriters, to purchase the Bonds which such defaulting Underwriter or Underwriters agreed but failed to purchase. In the event that any Underwriter or Underwriters default in their obligations to purchase Bonds hereunder, the Company may by prompt written notice to non-defaulting Underwriters postpone the Closing Date for a period of not more than seven full business days in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents, and the Company will promptly file any amendments to the Registration Statement or supplements to the Prospectus which may thereby be made necessary. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve an Underwriter from liability for its default. 11. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations and warranties of the Company and of or on behalf of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter or the Company or any of its officers or directors or any controlling person, and will survive delivery of and payment for the Bonds.
