Each Additional Lender agrees that, upon the Amendment Date, such Additional Lender will be a Lender for all purposes of the Amended Credit Agreement and the other Loan Documents (as defined in the Amended Credit Agreement), and such Additional Lender will promptly perform in accordance with the terms thereof all obligations and requirements which are required to be performed by a Lender under the Amended Credit Agreement and the other Loan Documents (as defined in the Amended Credit Agreement). Each Additional Lender represents and warrants that (i) it has full power and authority, and has taken all action necessary, to execute and deliver this Amendment and to consummate the transactions contemplated hereby and to become a Lender under the Amended Credit Agreement, (ii) it meets all the requirements to be an assignee under Section 8.08(b)(iii), (v) and (vi) of the Amended Credit Agreement (subject to such consents, if any, as may be required under Section 8.08(b)(iii) of the Amended Credit Agreement), (iii) from and after the Amendment Date, it shall be bound by the provisions of the Amended Credit Agreement as a Lender thereunder and shall have the obligations of a Lender thereunder, (iv) it is sophisticated with respect to decisions to acquire assets of the type represented by its Commitment and either it, or the Person exercising discretion in making its decision to acquire such Commitment, is experienced in acquiring assets of such type, (v) it has received a copy of the Credit Agreement and this Amendment, and has received or has been accorded the opportunity to receive copies of the financial statements referred to in Section 4.01(g) of the Amended Credit Agreement and such other documents and information as it deems appropriate to make its own credit analysis and decision to enter into this Amendment and to extend its Commitment, and (vi) it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Amendment and to extend its Commitment to the Borrowers pursuant to the terms of this Amendment and the Amended Credit Agreement.

* The disposition of the Bath County hydroelectric generation facility may be structured in a variety of ways, including as an asset sale by Allegheny Generating Company, a Subsidiary of AESC, or as a sale of equity interests in Allegheny Generating Company by its shareholders.

I am Associate General Counsel for FirstEnergy Service Company and have acted as counsel to FirstEnergy Corp., an Ohio corporation (“FE”), and FE’s subsidiaries, The Cleveland Electric Illuminating Company, an Ohio corporation (“CEI”), Ohio Edison Company, an Ohio corporation (“OE”), The Toledo Edison Company, an Ohio corporation (“TE”), Monongahela Power Company, an Ohio corporation (“MP”, and together with FE, CEI, OE and TE, the “Specified Borrowers”, and each, a “Specified Borrower”), in connection with the execution and delivery of the Amendment, dated as of May 8, 2013 (the “Amendment”), to the Credit Agreement, dated as of June 17, 2011 (as amended by the amendment, dated as of May 8, 2012, and as so amended, the “Original Credit Agreement”, and as further amended by the Amendment, the “Credit Agreement”), by and among the Specified Borrowers, Jersey Central Power & Light Company, Metropolitan Edison Company, Pennsylvania Electric Company, Pennsylvania Power Company, The Potomac Edison Company, West Penn Power Company, the banks party thereto, The Royal Bank of Scotland plc, as Administrative Agent for the Lenders thereunder, the fronting banks party thereto and the swing line lenders party thereto. Capitalized terms used but not otherwise defined in this letter have the meanings assigned to them in the Credit Agreement. This letter is being furnished to you at the request of the Specified Borrowers pursuant to Section 4(a)(vi) of the Amendment. The Amendment, the Credit Agreement, the 2013 Amendment Fee Letter and the Notes delivered on the date hereof (the “Notes”) are sometimes referred to in this letter collectively as the “Loan Documents” and each individually as a “Loan Document”.

For purposes of this letter, I or persons under my supervision or control have reviewed executed originals or copies of executed originals of the Amendment and the agreements comprising the Original Credit Agreement. In addition, I or persons under my supervision or control have reviewed the Articles of Incorporation and Code of Regulations (as amended and restated, where applicable) of the Specified Borrowers, the resolutions of the Board of Directors of the Specified Borrowers and originals or copies of such other records, agreements, documents and other instruments and such certificates of public officials and of officers and representatives of the Specified Borrowers, and have satisfied ourselves as to such other matters, I or persons under my supervision or control have considered relevant or necessary as a basis for this letter. In such review, I or persons under my supervision or control have assumed the authorization, execution and delivery

of each document by, and the validity, binding nature and enforceability of each document against, each of the parties thereto (other than with respect to authorization, execution and delivery, the Specified Borrowers), the genuineness of all signatures, the legal capacity of natural persons, the conformity to original documents of all documents submitted to me as copies (whether or not certified and including facsimiles) and the authenticity of such latter documents and of all documents submitted to me as originals. In particular, I or persons under my supervision or control have reviewed and relied upon the in-house opinions and certificates of officials of the Company delivered in connection with the original authorization, execution and delivery of the Original Credit Agreement. As to various questions of fact relevant to this letter, I have relied, without independent investigation, upon certificates of public officials, certificates of officers of the Borrowers and representations and warranties of the Borrowers contained in the Credit Agreement.

I am a member of the Bar of the State of Ohio, and, for purposes of this letter, I do not hold myself out as an expert on the laws of any other jurisdiction. I express no opinion herein as to the application or effect of the laws of any jurisdiction other than the laws of the State of Ohio. The phrase “the laws of the State of Ohio” and similar phrases refers to the laws of the State of Ohio that are, in my experience, generally applicable to transactions of the type contemplated under the Credit Agreement, and specifically excludes (a) laws of any counties, cities, towns, municipalities and special political subdivisions and any agencies thereof; (b) zoning, land use, building code and construction laws; and (c) any antifraud, environmental, labor, tax, pension, employee benefit, antiterrorism, money laundering, insurance, antitrust, securities or intellectual property laws.

Based upon the foregoing and subject to the assumptions, exceptions, qualifications and limitations set forth herein, I am of the opinion that:

Except as disclosed in the Disclosure Documents of or relating to any Borrower, to my knowledge, there is no litigation or governmental proceeding, pending or threatened, before any Ohio court, governmental agency or arbitrator that would reasonably be expected to have a material adverse effect on such Borrower’s ability to perform its obligations under the Loan Documents to which it is a party.

No examination has been made of, and no opinion is expressed as to the effect of, any zoning ordinance or permit pertaining to the authority of the Borrowers to operate their respective properties or conduct their respective businesses.

I also express no opinion with respect to the following:

This letter and the matters addressed herein are as of the date hereof or such earlier date as is specified herein, and I undertake no, and hereby disclaim any, obligation to advise you of any

change in any matter set forth herein, whether based on a change in the law, a change in any fact relating to the Borrowers or any other Person or any other circumstance occurring after the date hereof. This letter is limited to the matters expressly stated herein, and no opinions are to be inferred or may be implied beyond the opinions expressly set forth herein.

I have assumed that no fraud, dishonesty, forgery, coercion, duress or breach of fiduciary duty exists or will exist with respect to any matter relevant to this letter. No examination has been made of, and no opinion is expressed as to the effect of, any zoning ordinance or permit pertaining to the authority of the Borrowers to own, lease or operate their properties or conduct their businesses.

This letter is limited to the matters expressly set forth herein, and no opinions are to be inferred or may be implied beyond the opinions expressly set forth herein.

This letter is solely for the benefit of the addressees hereof in connection with the transactions contemplated by the Loan Documents and may not be relied on by the addressees hereof for any other purpose or furnished or quoted to or relied on by any other Person (other than the permitted successors and assigns of such addressees under the Credit Agreement) for any purpose without my prior written consent; provided, however, a copy of this letter may be provided to (a) counsel for the addressees hereof, (b) your auditors and (c) regulatory agencies having jurisdiction over you.

I am Associate General Counsel for FirstEnergy Service Company and have acted as counsel to its affiliates, Metropolitan Edison Company, a Pennsylvania corporation (“Met-Ed”), Pennsylvania Power Company, a Pennsylvania corporation (“Penn”), Pennsylvania Electric Company, a Pennsylvania corporation (“Penelec”), and West Penn Power Company, a Pennsylvania corporation (“West-Penn”, and together with Met-Ed, Penn and Penelec, the “Specified Borrowers”, and each, a “Specified Borrower”), in connection with the execution and delivery of the Amendment, dated as of May 8, 2013 (the “Amendment”), to the Credit Agreement, dated as of June 17, 2011 (as amended by the amendment, dated as of May 8, 2012, and as so amended, the “Original Credit Agreement”, and as further amended by the Amendment, the “Credit Agreement”), by and among the Specified Borrowers, FirstEnergy Corp., The Cleveland Electric Illuminating Company, Jersey Central Power & Light Company, Monongahela Power Company, Ohio Edison Company, The Potomac Edison Company, The Toledo Edison Company, the banks party thereto, The Royal Bank of Scotland plc, as Administrative Agent for the Lenders thereunder, the fronting banks party thereto and the swing line lenders party thereto. Capitalized terms used but not defined in this letter shall have the meanings assigned to them in the Credit Agreement. This letter is being furnished to you at the request of the Specified Borrowers pursuant to Section 4(a)(vi) of the Amendment. The Amendment, the Credit Agreement, the 2013 Amendment Fee Letter and the Notes delivered on the date hereof (the “Notes”) are sometimes referred to in this letter collectively as the “Loan Documents” and each individually as a “Loan Document”.

In such review, I or persons under my supervision or control have assumed the authorization, execution and delivery

of each document by, and the validity, binding nature and enforceability of each document against, each of the parties thereto (other than with respect to authorization, execution and delivery, the Specified Borrowers), the genuineness of all signatures, the legal capacity of natural persons, the conformity to original documents of all documents submitted to me as copies (whether or not certified and including facsimiles) and the authenticity of such latter documents and of all documents submitted to me as originals. In particular, I or persons under my supervision or control have reviewed and relied upon the in-house opinions and certificates of officials of the Company delivered in connection with the original authorization, execution and delivery of the Original Credit Agreement. As to various questions of fact relevant to this letter, I have relied, without independent investigation, upon certificates of public officials, certificates of officers of the Borrowers and representations and warranties of the Borrowers contained in the Credit Agreement.

I am a member of the Bar of the Commonwealth of Pennsylvania, and, for purposes of this letter, I do not hold myself out as an expert on the laws of any other jurisdiction. I express no opinion herein as to the application or effect of the laws of any jurisdiction other than the laws of the Commonwealth of Pennsylvania. The phrase “the laws of the Commonwealth of Pennsylvania” and similar phrases refers to the laws of the Commonwealth of Pennsylvania that are, in my experience, generally applicable to transactions of the type contemplated under the Credit Agreement, and specifically excludes (a) laws of any counties, cities, towns, municipalities and special political subdivisions and any agencies thereof; (b) zoning, land use, building code and construction laws; and (c) any antifraud, environmental, labor, tax, pension, employee benefit, antiterrorism, money laundering, insurance, antitrust, securities or intellectual property laws.

Based upon the foregoing and subject to the assumptions, exceptions, qualifications and limitations set forth herein, I am of the opinion that:

their respective obligations under the Loan Documents will not (a) violate or result in a default under the Organizational Documents of any such Specified Borrower, (b) violate any applicable law of the Commonwealth of Pennsylvania.

No examination has been made of, and no opinion is expressed as to the effect of, any zoning ordinance or permit pertaining to the authority of the Borrowers to operate their respective properties or conduct their respective businesses.

I also express no opinion with respect to the following:

This letter and the matters addressed herein are as of the date hereof or such earlier date as is specified herein, and I undertake no, and hereby disclaim any, obligation to advise you of any change in any matter set forth herein, whether based on a change in the law, a change in any fact relating to the Borrowers or any other Person or any other circumstance occurring after the date

hereof. This letter is limited to the matters expressly stated herein, and no opinions are to be inferred or may be implied beyond the opinions expressly set forth herein.

I have assumed that no fraud, dishonesty, forgery, coercion, duress or breach of fiduciary duty exists or will exist with respect to any matter relevant to this letter. No examination has been made of, and no opinion is expressed as to the effect of, any zoning ordinance or permit pertaining to the authority of the Borrowers to own, lease or operate their properties or conduct their businesses.

This letter is limited to the matters expressly set forth herein, and no opinions are to be inferred or may be implied beyond the opinions expressly set forth herein.

This letter is solely for the benefit of the addressees hereof in connection with the transactions contemplated by the Loan Documents and may not be relied on by the addressees hereof for any other purpose or furnished or quoted to or relied on by any other Person (other than the permitted successors and assigns of such addressees under the Credit Agreement) for any purpose without my prior written consent; provided, however, a copy of this letter may be provided to (a) counsel for the addressees hereof, (b) your auditors and (c) regulatory agencies having jurisdiction over you.

We have acted as special New York counsel to FirstEnergy Corp., an Ohio corporation (“FE”), and its subsidiaries, The Cleveland Electric Illuminating Company, an Ohio corporation (“CEI”), Metropolitan Edison Company, a Pennsylvania corporation (“Met-Ed”), Ohio Edison Company, an Ohio corporation (“OE”), Pennsylvania Power Company, a Pennsylvania corporation (“Penn”), The Toledo Edison Company, an Ohio corporation (“TE”), Jersey Central Power & Light Company, a New Jersey corporation (“JCP&L”), Monongahela Power Company, an Ohio corporation (“MP”), Pennsylvania Electric Company, a Pennsylvania corporation (“Penelec”), The Potomac Edison Company, a Maryland and Virginia corporation (“PE”), and West Penn Power Company, a Pennsylvania corporation (together with FE, CEI, Met-Ed, OE, Penn, TE, JCP&L, MP, Penelec and PE, the “Borrowers”, and each, a “Borrower”), in connection with the execution and delivery of the Amendment, dated as of May 8, 2013 (the “Amendment”), to the Credit Agreement, dated as of June 17, 2011 (as heretofore previously amended by the amendment, dated as of May 8, 2012, and as so amended, the “Original Credit Agreement”, and as further amended by the Amendment, the “Credit Agreement”), by and among the Borrowers, the banks party thereto, The Royal Bank of Scotland plc, as Administrative Agent for the Lenders thereunder, the fronting banks party thereto and the swing line lenders party thereto. Capitalized terms used but not defined in this letter have the meanings assigned to them in the Credit Agreement. This letter is being furnished to you at the request of the Borrowers pursuant to Section 4(a)(vii) of the Amendment. The Amendment, the Credit Agreement, the 2013 Amendment Fee Letter and the Notes delivered on the date hereof (the “Notes”) are sometimes referred to in this letter collectively as the “Loan Documents” and each individually as a “Loan Document”.

In connection with this letter, we have reviewed executed originals or copies of executed originals of the Amendment and the agreements comprising the Original Credit Agreement. We also have reviewed copies of the Regulatory Orders (defined below) and originals or certified copies of such corporate records of each Borrower and other certificates and documents of officials of each Borrower and certain of their affiliates, public officials and others as we have deemed appropriate for purposes of this letter, and relied upon them to the extent we deem appropriate. As to various

questions of fact relevant to this letter, we have relied, without independent investigation, upon certificates of public officials, certificates of officers of each Borrower and representations and warranties of each Borrower contained in the Loan Documents. In addition, we have made no inquiry of any Borrower or any other Person (including Governmental Authorities) regarding any judgments, orders, decrees, franchises, licenses, certificates, registrations, permits or other public records or agreements to which any Borrower is a party other than those described herein, and our knowledge of any such matters is accordingly limited.

We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all copies submitted to us as conformed, certified or reproduced copies. We also have assumed (a) the due organization, valid existence and good standing under the laws of its jurisdiction of incorporation of each party to each Loan Document, (b) the legal capacity of natural persons, (c) the corporate or other power and due authorization of each Person not a natural person to execute, deliver and perform its obligations under each Loan Document to which it is a party, (d) the due execution and delivery of each Loan Document by all parties thereto, (e) that each Loan Document constitutes the valid and binding obligation of each party thereto (other than the Borrowers), enforceable against such party in accordance with its terms, (f) that the execution, delivery and performance by each party to the Loan Documents do not, and will not, require the consent or approval of its shareholders, other than such consents and approvals as have been duly obtained, given or accomplished and are in full force and effect, and will not result in a breach or violation of any provision of its Organizational Documents, (g) that the execution, delivery and performance by any party to the Loan Documents will not result in (i) a breach of or constitute a default under any agreement or instrument to which it is a party (other than, with respect to such Borrowers, those of the Borrowers listed on Schedule I hereto) or (ii) a violation of any law (other than, in the case of any Borrower, any Included Law (as defined herein)) or any order, rule, regulation or determination of any Governmental Authority applicable to it (other than, in the case of any Borrower, its Regulatory Order), (h) that all required Governmental Action (other than, in the case of any Borrower, under any Included Law) for the execution and delivery by each party to any Loan Document, the performance by it of its obligations thereunder or the consummation by it of any transaction contemplated thereby have been obtained or taken, (i) that the Approvals (other than the Met-Ed FERC Order, the Penn FERC Order, the JCP&L FERC Order, the MP FERC Order, the Penelec FERC Order, the PE FERC Order and the West-Penn FERC Order (collectively, the “Regulatory Orders”)) are in full force and effect and (j) notwithstanding any provision contained in any agreement or instrument listed on Schedule I hereto selecting any law other than the laws of the State of New York as the governing law thereof, such agreement or instrument is governed by the laws of the State of New York.

In addition, we also have assumed that, other than the Amendment, there are no documents or agreements (whether oral or written) between the parties that in any way supplement, modify, amend, alter, conflict with, terminate or revoke the terms of the Original Credit Agreement. We also have assumed that the terms of the Original Credit Agreement remain in full force and effect (except as amended pursuant to the Amendment) and that no course of dealing or other acts or omissions by the parties to the Original Credit Agreement have occurred that would impair in any respect the enforceability of the Original Credit Agreement in accordance with its terms.

Based upon the foregoing and subject to the assumptions, exceptions, qualifications and limitations set forth herein, we are of the opinion that:

1.Each Loan Document constitutes a valid and binding obligation of each Borrower     party thereto, enforceable against each such Borrower in accordance with its     terms.

2.No Governmental Action is or will be required under any Included Law for the     due execution and delivery by the Borrowers of the Amendment, the 2013     Amendment Fee Letter and the Notes or the performance by the Borrowers of     their respective obligations under the Loan Documents, other than (i) the     Regulatory Orders, each of which is in full force and effect as of the date hereof,     and (ii) such Governmental Action as may be required after the date hereof in     connection with the performance by the Borrowers of the covenants set forth in     Sections 5.01(a) and (b) of the Credit Agreement.

3.The execution and delivery by the Borrowers of the Amendment, the 2013     Amendment Fee Letter and the Notes and the performance by the Borrowers of     their respective obligations under the Loan Documents, do not (i) result in a     violation of any law, rule or regulation of any Included Law, (ii) violate any     Regulatory Order or (iii) result in a breach of or constitute a default under, or     result in the creation or imposition of any Lien upon any property of any     Borrower pursuant to, any agreement or instrument of such Borrower listed on     Schedule I hereto.

A.We express no opinion as to the Laws (as defined below) of any jurisdiction other than the Included Laws. We have made no special investigation or review of any published constitutions, treaties, laws, rules or regulations or judicial or administrative decisions (“Laws”), other than a review of (i) the Laws of the State of New York and (ii) the Federal Laws of the United States of America. For purposes of this letter, the term “Included Laws” means the items described in clauses (i) and (ii) of the preceding sentence that are, in our experience, normally applicable to transactions of the type contemplated by the Loan Documents. The term Included Laws specifically excludes (i) Laws of any counties, cities, towns, municipalities and special political subdivisions and any agencies thereof; (ii) zoning, land use, building code and construction Laws; (iii) Federal Reserve Board margin regulations; and (iv) any antifraud, environmental, labor, tax, pension, employee benefit, antiterrorism, money laundering, investment company, insurance, antitrust, securities or intellectual property Laws.

B.When used in this letter, the phrases “known to us”, “to our knowledge” and similar phrases (i) mean the conscious awareness of facts or other information by (a) the lawyer in our firm who signed this letter, (b) any lawyer in our firm actively involved in negotiating and preparing the Loan Documents and (c) solely as to information relevant to a particular opinion, issue or confirmation regarding a particular factual matter, any lawyer in our firm who is primarily responsible for providing the response concerning that particular opinion, issue or confirmation; and (ii) do not require or imply (a) any examination of this firm’s, any such lawyer’s or any other Person’s files, (b) that any inquiry be made of the client, any lawyer (other than the lawyers described above) or any other Person or (c) any review or examination of any agreements, documents,

certificates, instruments or other papers (including, but not limited to, the exhibits and schedules to the Loan Documents and the various papers referred to in or contemplated by the Loan Documents and the respective exhibits and schedules thereto) other than the Loan Documents, the company records referred to in the second paragraph of this letter and the agreements and instruments of the Borrowers listed on Schedule I hereto.

C.The opinions expressed in this letter are subject to and qualified and limited by (i) applicable bankruptcy, insolvency, fraudulent transfer and conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally from time to time in effect; (ii) general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity); (iii) principles of commercial reasonableness and unconscionability and an implied covenant of good faith and fair dealing; (iv) the power of the courts to award damages in lieu of equitable remedies; and (v) securities Laws and public policy underlying such Laws with respect to rights to indemnification and contribution. Although it appears that the requirements of Section 5-1401 of the New York General Obligations Law have been met, we express no opinion on whether the choice of law provision in Section 9 of the Amendment or Section 8.09 of the Credit Agreement would raise any issues under the United States constitution or in equity that would affect whether courts in New York would enforce the choice of New York law to govern the Amendment or the Credit Agreement. We also have assumed that the choice of law of the State of New York as the governing law of the Amendment and the Credit Agreement would not result in a violation of an important public policy of another state having greater contacts with the transactions contemplated by the Loan Documents than the State of New York.

D.This letter and the matters addressed herein are as of the date hereof or such earlier date as is specified herein, and we undertake no, and hereby disclaim any, obligation to advise you of any change in any matter set forth herein, whether based on a change in the law, a change in any fact relating to any Borrower or any other Person or any other circumstance occurring after the date hereof. This letter is limited to the matters expressly stated herein, and no opinions are to be inferred or may be implied beyond the opinions expressly set forth herein.

E.We have assumed that no fraud, dishonesty, forgery, coercion, duress or breach of fiduciary duty exists or will exist with respect to any matter relevant to this letter.

F.We express no opinion as to (i) the financial condition or solvency of any Borrower; (ii) the compliance of the Loan Documents or the transactions contemplated thereby with, or the effect on any of the opinions expressed herein of, the antifraud provisions of Federal and state securities Laws; (iii) the compliance of the transactions contemplated by the Loan Documents with any Laws applicable to any Person other than the Borrowers; (iv) the ability (financial or otherwise) of any Borrower or any other Person to meet its obligations under the Loan Documents; (v) the conformity of the Loan Documents to any term sheet or commitment letter; or (vi) any provision of any Loan Document that would, to the extent not permitted by applicable Law, restrict, waive access to or vary legal or equitable remedies or defenses (including, but not limited to, a right to notice of and hearing on matters relating to prejudgment remedies, service of process, proper jurisdiction and venue, forum non conveniens and the right to trial by jury) or the right to collect damages (including, but not limited to, actual, consequential, special, indirect, incidental, exemplary and punitive damages). In addition, we express no opinion as to any breach of or default under any

agreement or instrument of any Borrower listed on Schedule I hereto to the extent any such breach or default is determined by reference to any numerical ratio (financial or otherwise), borrowing base calculation, percentage or dollar amount limitation or other financial, accounting or similar calculation or determination.

G.For purposes of this letter, the phrase “transactions of the type contemplated by the Loan Documents” and similar phrases mean (i) the making of Advances and the issuance of Letters of Credit by the Lenders party to the Credit Agreement and (ii) the performance by the Borrowers of their respective obligations under the Loan Documents.

H.This letter is solely for your benefit, and no other Person (other than your permitted successors and assigns under the Credit Agreement) shall be entitled to rely upon this letter. Without our prior written consent, this letter may not be quoted, in whole or in part, or otherwise referred to in any document and may not be furnished or otherwise disclosed to or used by any other Person; provided, however, a copy of this letter may be provided to (i) counsel for the addressees hereof, (ii) your auditors and (iii) regulatory agencies having jurisdiction over you.

We have acted as special New Jersey counsel for Jersey Central Power & Light Company, a New Jersey corporation (the “Company”), in connection with the Amendment, dated May 8, 2013 (the “2013 Amendment”) to the Credit Agreement, dated as of June 17, 2011 (the “Original Credit Agreement” and as amended by the Amendment, dated as of May 8, 2012 (the “2012 Amendment”) and the 2013 Amendment, the “Credit Agreement”), among the Borrowers, the Lenders party thereto, The Royal Bank of Scotland plc, as Administrative Agent for the Lenders thereunder, the fronting banks party thereto and the swing line lenders party thereto. Terms defined in the Credit Agreement are used herein as therein defined, unless otherwise defined herein. This opinion letter is being delivered to you pursuant to Section 4(a)(viii) of the 2013 Amendment.

In connection with this opinion letter, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws of the Company, corporate resolutions of the Company and such other documents and records, and other instruments as we have deemed appropriate for purposes of the opinions set forth herein, including the following documents (the 2013 Amendment, the Credit Agreement, the 2013 Amendment Fee Letter and the Notes delivered by the Company on the date hereof are referred to herein as the “Loan Documents”):

(a)    the 2012 Amendment;

(b)    the 2013 Amendment; and

(c)    the Original Credit Agreement.

We have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of the documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as certified, facsimile or photostatic copies, and the authenticity

of the originals of all documents submitted to us as copies. We have also assumed that the Loan Documents constitute valid and binding obligations of each party thereto other than the Company.

As to any facts that are material to the opinions hereinafter expressed that we did not independently establish or verify, we have relied without investigation upon the representations of the Company contained in the Loan Documents and upon certificates of officers of the Company.

In rendering the opinions set forth herein, whenever a statement or opinion set forth therein is qualified by “to our knowledge,” “known to us” or by words of similar import, it is intended to indicate that, during the course of our representation of the Company in the subject transaction, no information has come to the attention of those lawyers in our firm who have rendered legal services in connection with such transaction that gives us actual knowledge of the inaccuracy of such statement or opinion.

Based upon and subject to the foregoing, and to the limitations and qualifications described below, we are of the opinion that:

1.    The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of New Jersey, and has all corporate powers required to carry on its business as now conducted and to maintain and operate its property and business.

2.    No Governmental Action of any Governmental Authority of the State of New Jersey is or will be required for (a) the due execution or delivery by the Company of any Loan Document or the performance by the Company of its obligations thereunder or (b) the consummation by the Company of any transaction contemplated by the Loan Documents, other than such Governmental Action as may be required as a condition to the exercise by the Company of its rights under Section 2.06(b) or Section 2.07 of the Credit Agreement and such Governmental Action as may be required after the date hereof in connection with the performance by the Company of the general covenants set forth in Sections 5.01(a) and (b) of the Credit Agreement.

3.    The execution and delivery by the Company of each of the Loan Documents, the performance by the Company of its obligations under the Loan Documents, the consummation by the Company of the transactions contemplated by any Loan Document, and compliance by the Company with the provisions thereof, will not result in (a) a breach or violation of, or conflict with, any of the provisions of its Amended and Restated Certificate of Incorporation or Amended and Restated Bylaws or (b) a breach or violation of, or conflict with, any New Jersey State law, rule or regulation, or any determination of which we are aware of a New Jersey State court, regulating authority or other Governmental Authority of the State of New Jersey applicable to the Company, now in effect and customarily applicable to transactions of the type contemplated in the Loan Documents.

4.    The execution, delivery and performance by the Company of each of the Loan Documents are within its corporate powers, have been duly authorized by all necessary corporate action on the part of the Company and did not, do not, and will not require the consent or approval of the Company's shareholders.

Very truly yours,

We have acted as special counsel in the Commonwealth of Virginia to The Potomac Edison Company, a Virginia and Maryland corporation (the “Company”), in connection with the financing transactions contemplated by that certain Amendment dated as of May 8, 2013 (the “2013 Amendment”), by and among the Company, FirstEnergy Corp., The Cleveland Electric Illuminating Company, Metropolitan Edison Company, Ohio Edison Company, Pennsylvania Power Company, The Toledo Edison Company, Jersey Central Power & Light Company, Monongahela Power Company, Pennsylvania Electric Company, West Penn Power Company, the banks, financial institutions and other institutional lenders party thereto from time to time (the “Lenders”), and The Royal Bank of Scotland plc, as administrative agent for the Lenders (the “Administrative Agent”). Capitalized terms used herein without definitions shall have the meanings given to them in the Credit Agreement (as defined below). This opinion is being furnished to you pursuant to Section 4(a)(ix) of the Amendment.

In connection with the foregoing, we have examined executed counterparts or facsimile or photostatic copies of executed counterparts of the following documents:

1.    the Credit Agreement dated as of June 17, 2011, by and among the Company, FirstEnergy Corp., The Cleveland Electric Illuminating Company, Metropolitan Edison Company, Ohio Edison Company, Pennsylvania Power Company, The Toledo Edison Company, American Transmission Systems, Incorporated, Jersey Central Power & Light Company, Monongahela Power Company, Pennsylvania Electric Company, West Penn Power Company, the Lenders and the Administrative Agent (as amended by the Amendment dated May 8, 2012 (the “2012 Amendment”) and the 2013 Amendment, the “Credit Agreement”);

2.    the Promissory Notes dated as of May 8, 2013 executed and delivered by the Company (the “Notes”);

3.     the 2012 Amendment;

4.    the 2013 Amendment;

5.    the Company’s Articles of Restatement adopted by unanimous consent of the shareholders on April 19, 2000, certified by an officer of the Company on the date hereof (the

“Articles”), and the By-laws, as amended through February 28, 2012 (the “Bylaws” and, together with the Articles, the “Governing Documents”);

6.    the resolutions from the Annual Organization Meeting of the Board of Directors of the Company dated May 18, 2011, approving the transactions contemplated by the Credit Agreement (the “2011 Resolutions”);

7.    the resolutions from the Meeting of the Board of Directors of the Company held January 27, 2012 (the “2012 Resolutions” and, together with the 2011 Resolutions, the “Resolutions”); and

8.    the certificate of good standing dated May 6, 2013, issued by the State Corporation Commission of the Commonwealth of Virginia (the “SCC”) with respect to the Company (the “Good Standing Certificate”).

The documents referenced in Paragraphs 2 and 4 above may be referred to collectively herein as the “Opinion Documents.”

We have also examined originals or copies of such other agreements, corporate records, instruments and certificates (including the Opinion Certificate attached hereto as Exhibit A), certificates of public authorities and such matters of law as we have deemed necessary for the purpose of rendering this opinion. To the extent we deemed necessary for purposes of this opinion, we have relied upon (i) the statements and representations of officers of the Company as to factual matters, (ii) the corporate records provided to us by such officers and (iii) certificates and other documents obtained from public officials. We have relied as to factual matters on the representations and warranties contained in the Opinion Documents and the Credit Agreement, and we have assumed the completeness and accuracy of all such representations and warranties as to factual matters.

We have assumed the genuineness of all signatures, the legal capacity of all individuals who have executed all documents we have reviewed, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as certified, photostatic, reproduced or conformed copies. We have also assumed that the documents have been duly authorized, executed and delivered by each of the parties thereto (other than the Company, solely in respect of authorization of the Opinion Documents under Virginia law as expressly covered in opinion paragraph 3 below) and are enforceable in accordance with their terms against such parties and that the execution, delivery and performance of the documents by each of the parties thereto (other than the Company, solely in respect of Virginia law matters expressly covered in the opinions set forth in opinion paragraph 2 and opinion paragraph 4 below) does not and will not result in a breach of, or constitute a default under, any agreement, instrument or other document to which such party is a party.

In rendering this opinion, our examination of matters of law has been limited to, and we express no opinion as to the law of any jurisdiction other than, the laws of the Commonwealth of Virginia.

Based upon the foregoing, and such other documents and matters as we have deemed necessary and appropriate to render the opinions set forth below, and subject to the limitations, assumptions and qualifications noted herein, we are of the opinion that:

1.    The Company is a corporation validly existing in the Commonwealth of Virginia and has the Virginia corporate power and authority to execute and deliver the Opinion Documents and to perform its obligations thereunder and under the Credit Agreement. Based solely on the Good Standing Certificate, the Company is in good standing under the laws of the Commonwealth of Virginia as of the date of such certificate.

2.    The execution and delivery of the Opinion Documents by the Company, the performance by the Company of its obligations under each of the Opinion Documents and the Credit Agreement and consummation of the transactions contemplated thereby do not violate the Governing Documents.

3.    The execution and delivery of the Opinion Documents by the Company, the performance by the Company of its obligations under each of the Opinion Documents and the Credit Agreement and consummation of the transactions contemplated thereby have been duly authorized by all necessary Virginia corporate action of the Company. The Opinion Documents have been duly executed and delivered by the Company. We note that the Resolutions authorize borrowings under the Credit Agreement during calendar year 2013 and thereafter until the Board of the Company adopts subsequent short-term indebtedness financing resolutions.

4.    We express no opinion with regard to any additional Virginia corporate approvals or consents that may be required to be obtained by the Company in connection with (i) any borrowings requested by the Company after the calendar year 2013 until May 8, 2018, as permitted by the 2013 Amendment, or (ii) the exercise by the Company of its rights under Section 2.06(c) of the Credit Agreement and the opinion set forth in this opinion paragraph 3 is subject in all respects to the foregoing qualifications and exclusions.

5.    The execution and delivery of the Opinion Documents by the Company, the performance by the Company of its obligations under each Opinion Document and the Credit Agreement and consummation of the transactions contemplated thereby, do not violate any Virginia law, rule or regulation that we, based on our experience, recognize as applicable to the Company in a transaction of this type.

6.    No filing with, notice to, or consent, approval, authorization or order of any governmental authority of the Commonwealth of Virginia is required to be made or obtained in connection with the execution and delivery of the Opinion Documents by the Company, the performance by the Company of its obligations under each Opinion Document and the Credit Agreement and the consummation of the transactions contemplated thereby.

We express no opinion regarding (1) compliance with any telecommunications law, (2) the laws of any municipality or any local government within any state, (3) antitrust and unfair competition laws, (4) securities laws and regulations, (5) environmental laws or regulations, (6) zoning or land use laws or regulations, (7) fiduciary duties, (8) pension and employee benefit laws and regulations, (9) tax laws and regulations, (10) labor laws and regulations, (11) federal

contract law, (12) the USA Patriot Act of 2001 and the rules, regulations and policies promulgated thereunder and any foreign assets control regulations of the United States Treasury Department or any enabling legislation or orders relating thereto or similar laws, rules or regulations, (13) the effect of racketeering or criminal or civil forfeiture laws, (14) the Dodd-Frank Wall Street Reform and Consumer Protection Act or any rules or regulations thereunder or (15) commodities laws, including any document or provision constituting a ‘swap’ within the meaning of the Commodity Exchange Act of 1936, as amended, or any part thereof.

We have assumed for purposes of the opinions given in Paragraphs 2, 4 and 5 above that (i) the Company will obtain all permits and governmental approvals required in the future, and take all actions similarly required, relevant to subsequent consummation of the transactions contemplated by the Opinion Documents and the Credit Agreement or performance of the Opinion Documents and the Credit Agreement and (ii) all parties to the Opinion Documents and the Credit Agreement will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions thereof.

We express no opinion as to any accounting, financial or economic matters or the accuracy as to factual matters of any representation, warranty, data or other information, whether oral or written, that may have been made by any entity involved in the transaction described above, whether named herein or otherwise.

The opinions expressed in this letter are solely for the use of the Administrative Agent, the Lenders and their successors and permitted assigns and it may not be relied upon by any other person, firm or entity. Copies of this opinion may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, (ii) any person conducting a due diligence inquiry with respect to any addressee hereof, or (iii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body and its successor and assigns, and may not be relied on by any other person without our prior written approval. At your request, we hereby consent to reliance hereon by any future permitted assignee (“Additional Lender”) of the addressees' interest in the Loans, on the condition and understanding that (i) in no event shall any Additional Lender have any greater rights with respect hereto than the original addressees of this letter on the date hereof nor, in the case of any Additional Lender that becomes a Lender by assignment, any greater rights than its assignor, (ii) in furtherance and not in limitation of the foregoing, our consent to such reliance shall in no event constitute a reissuance of the opinions expressed herein or otherwise extend any statute of limitations period applicable hereto on the date hereof, and (iii) any such reliance also must be actual and reasonable under the circumstances relating to changes in law, facts of any other developments known to or reasonably knowable by such Additional Lender at such time. This opinion speaks as of its date and does not purport to address matters which may arise after such date. We expressly disclaim any obligation to advise you of any changes of law or facts that may hereafter come or be brought to our attention which would alter the opinions or advice herein set forth.

This opinion is being delivered and should be understood with reference to customary practice.  See "Statement on the Role of Customary Practice in the Preparation and Understanding of Third-Party Legal Opinions," 63 BUS. LAW. 1277 (2008).

Finally, our opinions and advice set forth herein are limited to the matters expressly set forth herein, and no opinion or advice is implied or may be inferred beyond the matters expressly so stated.

Anthony J. Alexander

Mark T. Clark

Charles E. Jones

Ladies and Gentlemen:

We have served as special Maryland counsel to The Potomac Edison Company, a corporation incorporated in the State of Maryland and the Commonwealth of Virginia (the “Borrower”), in connection with that certain amendment dated as of May 8, 2013 (the “2013 Amendment”), among the Borrower, certain other borrowers named therein, the Lenders party thereto, The Royal Bank of Scotland plc, as Administrative Agent for the Lenders thereunder, the fronting banks party thereto and the swing line lenders party thereto. This opinion is being furnished to you at the request of the Borrower pursuant to Section 4(a)(x) of the 2013 Amendment. Capitalized terms used but not defined herein shall have the meanings assigned to them in that certain credit agreement dated as of June 17, 2011 (the “Original Credit Agreement,” and as amended by the amendment as of May 8, 2012 (the “2012 Amendment”) and by the 2013 Amendment, the “Amended Credit Agreement”), among the Borrower, FirstEnergy Corp., The Cleveland Electric Illuminating Company, Metropolitan Edison Company, Ohio Edison Company, Pennsylvania Power Company, The Toledo Edison Company, American Transmission Systems, Incorporated, Jersey Central Power & Light Company, Monongahela Power Company, Pennsylvania Electric Company, West Penn Power Company, The Royal Bank of Scotland plc, as Administrative Agent for the Lenders thereunder, the fronting banks party thereto, the swing line lenders party thereto and the Lenders party thereto. We did not participate in the negotiation or drafting of any of the Loan Documents (as defined below).

In such capacity, we have reviewed the following documents (collectively, the “Documents”):

(a)    the Borrower’s Articles of Amendment and Restatement (Maryland) and Articles of Restatement (Virginia) as currently in effect (the “Charter”), certified as of a recent date by the State Department of Assessments and Taxation of Maryland (the “SDAT”);

(b)    the by-laws of the Borrower, as amended, as in effect on the date hereof (the “By-laws”), as certified by an officer of the Borrower;

(c)    the 2013 Amendment;

(d)    the Original Credit Agreement, the 2012 Amendment and the Notes delivered by the Borrower on the date hereof (the “Notes”) (collectively with the 2013 Amendment, the “Loan Documents”);

(e)    resolutions adopted by the Board of Directors of the Borrower relating to the approval of the Loan Documents (the “Board Resolutions”);

(f)    a good standing certificate for the Borrower, dated a recent date, issued by the SDAT;

(g)    a certificate executed by an officer of the Borrower, dated as of the date hereof (the “Officer’s Certificate”); and

(h)    such other documents as we have considered necessary to the rendering of the opinion expressed below.

In examining the Documents, and in rendering the opinion set forth below, we have assumed, without independent investigation, the following: (a) each of the parties to the Documents (other than the Borrower) has duly and validly authorized, executed and delivered each of the Documents and each instrument, agreement and other document executed in connection with the Documents to which such party (other than the Borrower) is a signatory and each such party's (other than the Borrower’s) obligations set forth in the Documents, are its legal, valid and binding obligations, enforceable in accordance with their respective terms; (b) each person executing any such instrument, agreement or other document on behalf of any such party (other than the Borrower) is duly authorized to do so; (c) each natural person executing any such instrument, agreement or other document is legally competent to do so; (d) the Documents accurately describe and contain the mutual understandings of the parties, there are no oral or written modifications of or amendments or supplements to the Documents and there has been no waiver of any of the provisions of the Documents by actions or conduct of the parties or otherwise; and (e) all documents submitted to us as originals are authentic, all documents submitted to us as certified or photostatic copies or telecopies or portable document file (".PDF") copies conform to the original documents (and the authenticity of the originals of such copies), all signatures on all documents submitted to us for examination (and including signatures on photocopies, telecopies and .PDF copies) are genuine, and all public records reviewed are accurate and complete. We have also assumed that without in any way affecting any opinion previously delivered by us with respect to the Original Credit Agreement, the Original Credit Agreement and the 2012 Amendment continue to constitute the valid and binding obligations of each party thereto, enforceable against each such party in accordance

with their terms immediately prior to the amendment thereof and our delivery of this opinion to you. As to all factual matters relevant to the opinion set forth below, we have relied upon the representations and warranties made in the 2013 Amendment and in the Officer’s Certificate as to the factual matters set forth therein, which we assume to be accurate and complete, and on the written statements and representations of public officials and others and our review of the Documents.

Based upon and subject to the foregoing and having regard for such legal considerations we deem relevant, we are of the opinion that, as of the date hereof:

1.    The Borrower is validly existing as a corporation in good standing under the laws of the State of Maryland.

2.    The execution, delivery and performance by the Borrower of the 2013 Amendment and the Notes and the consummation by the Borrower of the transactions contemplated thereby and by the Amended Credit Agreement have been duly authorized by all necessary corporate action on the part of the Borrower. The 2013 Amendment and the Notes have been duly executed and delivered by the Borrower.

3.    The execution, delivery and performance by the Borrower of the 2013 Amendment and the Notes do not, and the performance by the Borrower of its obligations thereunder and under the Amended Credit Agreement will not, (a) violate the Charter or By-laws, (b) violate any law, rule or regulation of the State of Maryland, (c) violate or conflict with any consent, authorization, permit, approval, decision, order, judgment or determination of any Governmental Authority of the State of Maryland, (d) result in or require the creation or imposition of any Lien upon or with respect to any of the assets of the Borrower or (e) so far as is known to us, conflict with any notice to or any filing with any Governmental Authority of the State of Maryland made by the Borrower.

4.    No authorization or approval or other action by, and no notice to or filing by the Borrower with, any Governmental Authority of the State of Maryland pursuant to any law, rule, regulation, decision, order, judgment or determination of the State of Maryland or any Governmental Authority of the State of Maryland is required for the due execution, delivery, recordation, filing or performance by the Borrower of the 2013 Amendment and the Notes, or for the consummation of the transactions contemplated thereby and by the Amended Credit Agreement, except such Governmental Action as may be required after the date hereof in connection with the performance by the Borrower of the general covenants set forth in Section 5.01(a) and (b) of the Amended Credit Agreement.

In addition to those set forth above, this opinion is subject to additional assumptions, qualifications and limitations as follows:

(a)    We have made no investigation of, and we express no opinion as to, the laws of any jurisdiction other than the laws of the State of Maryland. Without limiting the generality of the foregoing sentence, we express no opinion as to

compliance with or the applicability or effect of any U.S. federal utility company laws. To the extent that any documents referred to herein are governed by the laws of a jurisdiction other than the State of Maryland, we have assumed that the laws of such jurisdiction are the same as the laws of the State of Maryland. We note that the 2013 Amendment is to be construed under the laws of the State of New York.

(b)    This opinion concerns only the effect of the laws (exclusive of the principles of conflict of laws) of the State of Maryland as currently in effect. We assume no obligation to supplement this opinion if any applicable laws change after the date hereof or if any facts or circumstances come to our attention after the date hereof that might change this opinion.

(c)    We express no opinion as to compliance with (i) the securities (or “blue sky”) laws of the State of Maryland, (ii) the land use or subdivision laws or regulations of the State of Maryland or any political subdivision thereof, (iii) the environmental laws or regulations of the State of Maryland or (iv) the pension and employee benefit laws or regulations of the State of Maryland.

(d)    This opinion is limited to the matters set forth herein, and no other opinion should be inferred beyond the matters expressly stated.

(e)    The phrase “known to us” is limited to the actual knowledge of the lawyers at our firm who have performed legal services in connection with the issuance of this opinion.

(f) We note that the Board Resolutions authorized borrowings under the Amended Credit Agreement during calendar years 2012 and 2013 and thereafter until the Board of Directors of the Borrower adopts subsequent “short-term indebtedness” financing resolutions. We express no opinion with regard to any additional State of Maryland corporate approvals or consents required by the Maryland General Corporation Law or any Governmental Authority of the State of Maryland that may be required to be obtained by the Borrower in connection with any Borrowings requested by the Borrower after the calendar year 2013, and our opinion in paragraph 2 above is subject in all respects to the foregoing qualification and exclusion.

(g) Our opinion expressed in paragraph 3 above is based upon our consideration of only those laws, rules, regulations or determinations of any Maryland State court, regulating authority or other Governmental Authority of the State of Maryland, if any, which are required under those Maryland statutes and regulations which a lawyer licensed in the State of Maryland who routinely represents companies similar to the Borrower would reasonably believe are normally applicable to transactions of the type described in the 2013 Amendment.

(h)    With respect to our opinion in paragraph 4, if the Borrower incurs Indebtedness under the Amended Credit Agreement maturing more than 364 days after the date of incurrence of such Indebtedness in accordance with the proviso in

Section 2.07 of the Amended Credit Agreement, then Governmental Action in the form of prior authorization and approval of the incurrence of such Indebtedness will be required by a Governmental Authority of the State of Maryland.

The opinion expressed herein is subject to the effect of judicial decisions which may permit the introduction of parol evidence to modify the terms or the interpretation of agreements.

This opinion is being furnished to you for your benefit and, accordingly, may not be relied upon by, quoted in any manner to, or delivered to any other person or entity (other than (i) your permitted successors and assigns under the Amended Credit Agreement, (ii) King & Spalding LLP, special New York counsel to the Administrative Agent, in connection with the opinion to be issued by it dated the date hereof, (iii) counsel for and auditors of each Lender and (iv) the federal and state banking authorities having authority over such Lender) without, in each instance, our prior written consent. Notwithstanding the foregoing, a copy of this opinion letter may be delivered to any person who becomes a Lender in accordance with the provisions of the Amended Credit Agreement, and a copy of this opinion letter may be included in a closing set relating to the Amended Credit Agreement. Any such person may rely on the opinion expressed above as if this opinion letter were addressed and delivered to such person on the date hereof.

The Royal Bank of Scotland plc, as administrative agent, the fronting banks, the swing line lenders and the lenders party to the Credit Agreement referred to below

We have acted as special New York counsel to The Royal Bank of Scotland plc, individually and as administrative agent (the “Administrative Agent”), in connection with the preparation, execution and delivery of the Amendment, dated as of May 8, 2013 (the “2013 Amendment”), to the Credit Agreement, dated as of June 17, 2011 (the “Original Credit Agreement”, and as amended by the Amendment, dated as of May 8, 2012 (the “2012 Amendment”), and the 2013 Amendment, the “Credit Agreement”), among FirstEnergy Corp., an Ohio corporation, The Cleveland Electric Illuminating Company, an Ohio corporation, Metropolitan Edison Company, a Pennsylvania corporation, Ohio Edison Company, an Ohio corporation, Pennsylvania Power Company, a Pennsylvania corporation, The Toledo Edison Company, an Ohio corporation, Jersey Central Power & Light Company, a New Jersey corporation, Monongahela Power Company, an Ohio corporation, Pennsylvania Electric Company, a Pennsylvania corporation, The Potomac Edison Company, a Maryland and Virginia corporation and West Penn Power Company, a Pennsylvania corporation, the Administrative Agent, the fronting banks party thereto, the swing line lenders party thereto and the Lenders party thereto. Unless otherwise defined herein, terms defined in the Credit Agreement are used herein as therein defined. This opinion letter is being delivered pursuant to Section 4(a)(xi) of the 2013 Amendment.

In that connection, we have examined (i) counterparts of the 2013 Amendment, the 2012 Amendment and the Original Credit Agreement (collectively, the “Opinion Documents”), each executed by the Borrowers, ATSI, the Lenders party thereto, the Swing Line Lenders, the Administrative Agent and the Fronting Banks, and (ii) the other documents furnished to the Administrative Agent pursuant to Section 4(a) of the 2013 Amendment, including (without limitation) the opinions of (A) Gina K. Gunning, Esq., Associate General Counsel of FE and counsel for the Borrowers, (B) Bradley A. Bingaman, Esq., Associate General Counsel of FE and counsel for the Borrowers, (C) DLA Piper LLP (US), special counsel to PE, (D) Hunton & Williams LLP,

special counsel to PE, (E) Morgan, Lewis & Bockius LLP, special counsel to JCP&L, and (F) Akin Gump Strauss Hauer & Feld LLP, special counsel to the Borrowers (collectively, the “Borrowers’ Counsel Opinions”).

In our examination of the documents referred to above, we have assumed the authenticity of all such documents submitted to us as originals, the genuineness of all signatures, the due authority of the parties executing such documents and the conformity to the originals of all such documents submitted to us as copies. We have also assumed that each of the Lenders, the Swing Line Lenders, the Fronting Banks and the Administrative Agent has duly executed and delivered, with all necessary power and authority (corporate and otherwise), each Opinion Document to which such Person is stated to be a party. We have further assumed that you have evaluated, and are satisfied with, the creditworthiness of the Borrowers and the business and financial terms evidenced by the Loan Documents.

To the extent that our opinions expressed below require conclusions as to, or otherwise involve or relate to, matters of law that are governed by laws other than the law of the State of New York, we have assumed without independent investigation or inquiry the correctness of all opinions as to such matters set forth in the Borrowers’ Counsel Opinions, and our opinions expressed below are subject to the same assumptions, qualifications and limitations with respect to such matters as set forth in the Borrowers’ Counsel Opinions. As to matters of fact, we have relied solely upon the documents we have examined as described above and have made no independent investigation or inquiry to confirm any such matters. We note that we do not represent the Borrowers, and accordingly, are not privy to the nature or character of their business. Accordingly, for purposes of rendering the opinions below we have assumed that the Borrowers are subject only to statutes, rules, regulations, judgments, orders and other requirements of law generally applicable to general business corporations doing business in the State of New York.

Based upon the foregoing, and subject to the qualifications set forth below, we are of the opinion that:

Our opinions are subject to the following qualifications:

This opinion letter speaks only as of the date hereof, and we expressly disclaim any responsibility to advise you of any development or circumstance, including changes of law or fact, that may occur after the date of this opinion letter that might affect the opinions expressed herein. This opinion letter is furnished to the addressees hereof solely in connection with the transactions contemplated by the Credit Agreement, is solely for the benefit of the addressees hereof and may not be relied upon by any other Person or for any other purpose without our prior written consent. Notwithstanding the foregoing, this opinion letter may be relied upon by any Person that becomes a Lender after the date hereof in accordance with the provisions of the Credit Agreement as if this opinion letter were addressed and delivered to such Person on the date hereof. Any such reliance must be actual and reasonable under the circumstances existing at the time such Person becomes a Lender, taking into account any changes in law or facts and any other developments known to or reasonably knowable by such Person at such time.

Very truly yours,
