On March 31, 2018 (the “Petition Date”), FirstEnergy Solutions Corp. (“FES”), FirstEnergy Nuclear Operating Company (“FENOC”) and each of their respective direct and indirect subsidiaries (collectively, the “Debtors”) commenced voluntary chapter 11 cases (the “Chapter 11 Cases”) in the bankruptcy court for the Northern District of Ohio (the “Bankruptcy Court”). On April 20, 2018, (a) FirstEnergy Corp. (“FE”) and its affiliates and subsidiaries other than the Debtors (collectively, with FE, the “FENon-Debtor Parties”), (b) the ad hoc group of holders (the “Ad Hoc Noteholder Group”) of certain pollution control revenue bonds supported by notes issued by FirstEnergy Generation LLC (“FG”) and FirstEnergy Nuclear Generation LLC (“NG”) and certain unsecured notes issued by FES, and (c) the ad hoc group of Bruce Mansfield certificate holders (the “Mansfield Group” and, together with the Ad Hoc Noteholder Group, the “Supporting Creditors”) agreed on certain settlement terms that represented an agreement in principal between FE and the Supporting Creditors with respect to a settlement and compromise (the “Original Settlement”) of claims and causes of action between (i) the Debtors, on the one hand, and (ii) the FENon-Debtor Parties, on the other hand. In addition, the Mansfield Group’s support for the settlement set forth herein is subject to and conditioned upon the ultimate implementation of the agreement between the Mansfield Group and the Ad Hoc Group concerning the treatment of certain Mansfield-related claims set forth on the term sheet attached hereto asExhibit A(the “Mansfield Settlement”).

On July 31, 2018, the Debtors and the Official Committee of Unsecured Creditors (the “Committee” and with the Debtors, the FENon-Debtor Parties and the Supporting Creditors, the “Parties”) agreed to join the Original Settlement in consideration of certain modifications thereto (the “Modified Settlement”) which have been accepted by the FENon-Debtor Parties and the Supporting Creditors. The material terms and conditions of the Modified Settlement are set forth herein and shall be incorporated into a settlement agreement consistent with the terms herein and otherwise in form and substance reasonably acceptable to the Parties (the “Modified Settlement Agreement”).

Notwithstanding anything herein to the contrary, the Debtors have determined that the resolution of the Mansfield IT Claims (as defined in the Mansfield Settlement) set forth in the Mansfield Settlement is fair and reasonable and in the best interests of the Debtors’ estates to the extent such resolution is incorporated into a broader restructuring agreement acceptable to the Debtors, including, without limitation, a chapter 11 plan for the Debtors that is supported by the Debtors, the Mansfield Group and the Ad Hoc Group. The Debtors shall engage in good faith negotiations with the Mansfield Group (i) with respect to the resolution of all issues relating to the Leveraged Lease Transaction and the Mansfield ITs’ interests in Unit 1 of the Bruce Mansfield facility (other than the allowance of the Mansfield IT Claims), including without limitation, any issues related to operation of the facility and insurance proceeds from the January 2018 fire and (ii) concerning a proposed chapter 11 plan for the Debtors, and a related restructuring support agreement, that incorporates the treatment of the Mansfield IT Claims set forth in the Mansfield Settlement. Further, the Debtors and the FENon-Debtor parties shall use commercially reasonable efforts to provide all priority documents relating to the Mansfield IT Claims to the Committee by August 24, 2018 to assist the Committee in evaluating the reasonableness of the Mansfield Settlement.;provided,however, that nothing herein shall prejudice the rights of the Committee or any other party to the Mansfield Protocol (as defined herein) to seek production of documents in addition to the priority documents relating to the Mansfield IT Claims, in each case in accordance with the terms of the Mansfield Protocol.

Execution Version

The Modified Settlement is subject to: (i) approval by the FE, Allegheny Energy Supply Company, LLC (“AES”), and the Debtors’ boards of directors, (ii) acceptable documentation in definitive agreements, and (iii) Bankruptcy Court approval.

The Debtors shall seek Bankruptcy Court approval of the Modified Settlement via a motion pursuant to Federal Rule of Bankruptcy Procedure 9019 (the “9019 Motion”). The Parties shall finalize all documents related to the Modified Settlement, and the Debtors shall file the 9019 Motion, no later than August 24, 2018. The Debtors will obtain an order from the Bankruptcy Court approving the Modified Settlement no later than September 25, 2018.The date upon which the Bankruptcy Court enters an order approving the 9019 Motion shall be referred to herein as the “Settlement Effective Date.”

For the avoidance of doubt, nothing in this Term Sheet or the Modified Settlement determines, or will determine, the allocation of value under a plan of reorganization or liquidation of the Debtors, and all rights are reserved with respect to those issues.

THIS TERM SHEET DOES NOT CONSTITUTE AN OFFER OR A LEGALLY BINDING OBLIGATION OF THE DEBTORS OR ANY OTHER PARTY, NOR DOES IT CONSTITUTE AN OFFER OF SECURITIES OR A SOLICITATION OF THE ACCEPTANCE OR REJECTION OF ANY CHAPTER 11 PLAN FOR PURPOSES OF SECTIONS 1125 AND 1126 OF THE BANKRUPTCY CODE.

New FE Notes On the Plan Effective Date, and in consideration for the Releases described herein, FE will issue notes (“New FE Notes”) to the Debtors calculated as set forth below and with such other terms and conditions as follows:   •  The principal amount of the New FE Notes shall be $628 million less the amount, if any, of cash paid by FE to the Debtors under the intercompany tax sharing arrangement for the tax benefits related to the sale or deactivation, and received by the Debtors prior to or on the Plan Effective Date (defined below), of all or any portion of a nuclear or fossil plant, excluding the West Lorain Plant (the “Adjustment Amount”), it being understood that no losses related to any such sale or deactivation prior to the Effective Date have been included in the calculation of the principal amount of the New FE Notes as of the date hereof. All amounts due under the New FE Notes will be due and payable regardless of whether or not FE realizes such benefits. Should a sale or deactivation occur, a summary of the calculation of the Adjustment Amount shall be provided to the Parties at least fourteen (14) days prior to the Plan Effective Date, or as soon as reasonably practicable in the event the sale closes within fourteen (14) days of the Plan Effective Date, and, in the event the Adjustment Amount or the calculation thereof is not acceptable to one or more of the Parties, the Modified Settlement final documentation shall provide for a means of dispute resolution.   •  If the Adjustment Amount so paid to the Debtors on or prior to the Plan Effective Date is equal to or greater than $628 million, then no New FE Notes will be issued.   •�� On the Plan Effective Date, FE shall make a cash payment to the Debtors (the “Upfront Payment”) in an amount equal to the difference, if any, between the principal amount of the New FE Notes and the market price of the New FE Notes (as determined in reference to the yield curve of FE’s issued and outstanding senior notes (the “Existing FE Notes”) and agreed to among the Parties, while comparing the terms of the New FE Notes to the terms of the Existing FE Notes using customary market practices).   •  The principal amount of New FE Notes issued shall (i) bear a fixed interest rate equal to the then current yield for U.S. Government Treasury securities with the most comparable maturity date, interpolated based on customary market practice and (ii) be due December 31, 2022 (the “Maturity Date”), and (iii) be redeemable at par plus accrued interest at any time without premium or penalty.¹   •  The New FE Notes will rank equally and ratably in right of payment with, and will havenon-economic terms materially consistent with, the Existing FE Notes, and may be issued under an existing indenture for the Existing FE Notes.

¹  The intent is that the coupon and due date will cause the New FE Notes to trade at par, and to ensure that the market value of the New FE Notes, when combined with (i) any Adjustment Amount and (ii) any Upfront Payment, as noted in this paragraph, be $628 million.

•  FE shall use commercially reasonable efforts, at its own expense, to (i) cause the New FE Notes at issuance to be assigned a rating by at least two nationally-recognized credit rating agencies, which ratings shall be at the same level or higher than the ratings assigned by such agencies to the Existing FE Notes and (ii) promptly upon the Plan Effective Date, file one or more registration statements that will provide for (a) the registration of the issuance of the New FE Notes by FE on the Plan Effective Date, (b) an A/B exchange offer of identical securities (other than with respect to registration rights) promptly after the Plan Effective Date in accordance with standard market practice and/or (c) the establishment of a resale shelf to become effective promptly after the Plan Effective Date and remain effective until (i) the New FE Notes are no longer restricted in accordance with the U.S. Securities Act of 1933, as amended and (ii) all of the New FE Notes have been transferred by the selling noteholders named therein; provided, that in clauses (b) and (c) above, FE’s obligations referred to in this clause (ii) will be subject to standard “blackout” and other registration rights terms, including FE’s right to suspend its obligations hereunder for up to 90 days after the Plan Effective Date for customary reasons related to, among other things, the material completeness and accuracy of the information to be included or incorporated by reference in any such registration statement prospectus or prospectus supplement. •  The New FE Notes will be issued to the Debtors, and the Debtors may distribute the New FE Notes under a plan of reorganization or liquidation.

Cash Payment

On the Plan Effective Date, and in consideration for the Releases described herein, FE will make a cash settlement payment of $225 millionto the Debtors, which amount shall not be subject to setoff or reduction.

Sale Process

Commencing on the Settlement Effective Date, and in consideration for the Releases described herein: •  Sale of the Retail Book Assets. In connection with the sale of the Debtors’ Retail Book Assets, FE and FESC reaffirm each of their commitments contained in that certain letter agreement, dated July 12, 2018, by and among FESC, FE and FES. •  Other Asset Sales. The applicable FENon-Debtor Parties shall cooperate with the Debtors, or reorganized Debtors, as applicable, in their efforts to maximize the value realized from any sale process conducted by the Debtors by agreeing, among other things, to (i) participate in any ancillary transactions (on a commercially reasonable basis, which may include the incurrence of unreimbursed de minimis expenses (or additional costs to the extent reimbursed by the Debtors) by the FENon-Debtor Parties, and shall not require the FENon-Debtor Parties to undertake any action that will cause an adverse effect on, or result in a loss of rights without adequate consideration to, the FENon-Debtor Parties) reasonably necessary to consummate the transactions contemplated by the sale processes, (ii) assist in obtaining any required consents, waivers or approvals related to the transactions contemplated by the sale processes, and (iii) make FE and FESC personnel available to facilitate diligence and as otherwise necessary in furtherance of the Sale Process and the transactions contemplated thereby. •  Regulatory Exception: Notwithstanding the above, the FENon-Debtor Parties shall not be required to take any action, or omit to take any action, that would violate applicable law or any regulatory obligation.

Tax Sharing Agreement

The FENon-Debtor Parties and the Debtors will perform under the Intercompany Tax Sharing Agreement with respect to all periods or portions thereof ending on or before the Plan Effective Date. Under no circumstances shall FE take any action to terminate the Intercompany Tax Sharing Agreement prior to the Debtors’ emergence from chapter 11. On the Plan Effective Date, theFE-Non Debtor Parties will, in consideration for the Releases described herein, waive the 2017 overpayment that is due from any of the Debtors and reverse the purchase of NOLs booked in theNon-Utility Money Pool on or about March 16, 2018 for approximately $88 million related to Q1 and Q2 2018 estimated payments under the Intercompany Tax Sharing Agreement. On the Plan Effective Date, the FENon-Debtor Parties will guarantee the purchase of at least as many of the Debtors’ 2018 NOLs as would result in a payment of $66 million under the Intercompany Tax Sharing Agreement (the “$66 Million Floor”) for tax year 2018. The FE Non-Debtor Parties will perform under the Intercompany Tax Sharing Agreement for tax year 2018, but shall not guarantee the amount of purchased NOLs for tax year 2018 except for the $66 Million Floor. Thus, to the extent reimbursement for the FENon-Debtor Parties’ actual use of the Debtors’ NOLs is less than the $66 Million Floor for tax year 2018, the FENon-Debtor Parties shall provide the Debtors with the difference between $66 million and the amount of the Debtors’ NOLs actually purchased for such tax year.

Execution Version

FE shall perform under the Intercompany Tax Sharing Agreement consistent with historical practice and shall not take any action, or refrain from taking any action, with the primary purpose of reducing payments to the Debtors for the use of Debtor losses under the Intercompany Tax Sharing Agreement, provided, however, that the FENon-Debtor Parties will not be prohibited from taking any action, or refraining from taking any action, necessary to preserve $628 million of value for the worthless stock deduction. For the avoidance of doubt, the act of taking the worthless stock deduction, pursuant to the terms of the Modified Settlement, shall not be considered an action whose primary purposes is to reduce the payments to the Debtors for the use of Debtor losses under the Intercompany Tax Sharing Agreement.

Prior to the Plan Effective Date, FE and the Debtors shall enter into an amended tax matters agreement governing the rights and obligations of each party thereto with respect to certain tax matters and provide for, among other things:

•  The FENon-Debtor parties will, with the Debtors’ review and consultation, timely prepare the US federal income tax returns reflecting the Debtors’ membership in the FE consolidated tax group, as well as any and all state and local income or franchise/use tax returns for any tax period ending on or before the Plan Effective Date,provided,however, that the FENon-Debtor Parties shall not be required to take any action, or omit to take any action, that results in an adverse effect to any of theFE Non-Debtor Parties.

•  That the FENon-Debtor Parties shall not take a worthless stock deduction in respect of a date prior to the Plan Effective Date.

•  FE shall perform under the Intercompany Tax Sharing Agreement consistent with historical practice and shall not take any action, or refrain from taking any action, with the primary purpose of reducing payments to the Debtors for the use of Debtor losses under the Intercompany Tax Sharing Agreement, provided, however, that the FENon-Debtor Parties will not be prohibited from taking any action, or refraining from taking any action, necessary to preserve $628 million of value for the worthless stock deduction. For the avoidance of doubt, the act of taking the worthless stock deduction, pursuant to the terms of the Modified Settlement, shall not be considered an action whose primary purposes is to reduce the payments to the Debtors for the use of Debtor losses under the Intercompany Tax Sharing Agreement.

•  The Parties shall cooperate on developing an exit strategy that minimizes adverse tax consequences to the reorganized Debtors and their stakeholders,provided,however, that the FENon-Debtor Parties shall not be required to take any action, or omit to take any action, that results in an adverse effect to any of theFE Non-Debtor Parties.

•  FE shall cooperate with reasonable tax diligence inquiries from the Debtors and the Supporting Creditors regarding historical intercompany tax issues and tax consequences of different chapter 11 exit structures, including in connection with the Sale Process.

The plan of reorganization or liquidation shall include provisions that release the FE Released Parties of and from all past and present claims, liabilities and causes of action, whether known or unknown, contingent or unliquidated, that could be asserted against the FE Released Parties by any of the Debtors or their shareholders or creditors, effective as of the Plan Effective Date (the “Plan Release”). The order approving such plan and Plan Release shall be among the conditions precedent to FENon-Debtor Parties’ obligation to pay or perform the obligations specified in the Modified Settlement that are due on the Plan Effective Date. Such condition precedent will not be satisfied until the order approving such plan and Plan Release is a Final Order (as such term will be defined in the Modified Settlement Agreement). Failure to meet such conditions shall constitute a Condition Failure Scenario and entitle the FENon-Debtor Parties to terminate the Modified Settlement Agreement.

Execution Version

Upon the occurrence of the Condition Failure Scenario, the FENon-Debtor Parties shall additionally be entitled to reimbursement on a superpriority administrative basis for the actual costs of goods and services provided to the Debtors under this Modified Settlement pursuant to a methodology and limiting procedure to be set forth in the Modified Settlement Agreement. In the event that either (i) the Plan Effective Date does not occur by June 30, 2020 or (ii) the Chapter 11 cases convert to cases under chapter 7 of the Bankruptcy Code, the FENon-Debtor Parties may complete all remaining performance (except to the extent any performance is tendered by the FENon-Debtor Parties but not accepted by the Debtors or any successor to the Debtors) pursuant to this Modified Settlement Agreement and, upon doing so, shall be entitled in return to performance due under the Modified Settlement including the Party Releases. For clarification, under such circumstances FE shall be required to perform all obligations under the Modified Settlement, including the payment of cash and the FE Notes related obligations.

Employee Matters

The FENon-Debtor Parties shall agree to the following employee-related items. Nothing herein is intended to create any additional right or claims to coverage, including premium subsidies, or to create any vested right to such benefits for current retirees under any Health Care Plan(s) (as defined below) that do not otherwise currently exist. Such retirees will, at all times, be subject to the terms and conditions of such Health Care Plan(s) including, per the specific terms of the Health Care Plan(s), the reservation of the right by FE of the complete discretion to amend or terminate such Health Care Plan(s) or the access to such Health Care Plan(s). Pension, EDCP, LTIP, Group Life, Frozen and Banked Vacation and Retiree Medical •  Except with respect to the FE LTIP, from and after the Plan Effective Date, FE will pay all employee-associated claims and guarantees for the Debtors’ current and former employees as and when such obligations become due and payable under the applicable plan documents solely for (i) pension benefits under the FE Master Pension Plan, (ii) deferred compensation, supplemental pension and all other employee benefits provided under the FirstEnergy Corp. Amended and Restated Executive Deferred Compensation Plan Effective as of November 1, 2015, as amended, (iii) the 2016-2018 cycle of the LTIP awarded by FE, (iv) claims for retiree group life insurance provided under the FirstEnergy Corp. Group Life Plan (or similar predecessor plans) for employees of the Debtors who have retired on or before the Plan Effective Date, (v) frozen and banked vacation in accordance with the terms of such benefit plans and if applicable, collective bargaining agreements, and (vi) claims, includingopt-out payments and runoff or termination claims, related to retiree medical and prescription drug benefits or premium subsidies (“Retiree Medical Subsidies”) under the FirstEnergy Corp. Health Care Plan and any similar plans sponsored by FirstEnergy Corp. (any such plans, the “Health Care Plan(s)”) with respect to

Execution Version

any employees of the Debtors who have retired on or prior to the Settlement Effective Date, but only to the extent the Retiree Medical Subsidies are specifically provided for under a Health Care Plan and any retiree medical and prescription drug benefits and premium subsidies payable to current and future retirees under union sponsored plans under the collective bargaining agreements between FirstEnergy Nuclear Operating Company and International Brotherhood of Electric Workers, Local Union 29 and between Cleveland Electric Illuminating Company, FirstEnergy Service Company, First Energy Nuclear Operating Company, and FirstEnergy Generation, LLC and Utility Workers Union of America,AFL-CIO, Local Union 270 (the employee obligations described in clauses (i)-(vi) shall be referred to herein as “Certain Employee Related Obligations”). With respect to the 2016-2018 cycle of the FE LTIP, FE will pay the amounts which become vested as of March 1, 2019 to the participating employees of the Debtors no later than March 15, 2019.

Employee Retention and Severance Programs

•  Voluntary Enhanced Retirement Option (“VERO”). To the extent the Debtors elect to undertake any workforce reduction, other than with respect to FENOC employees, prior to the Plan Effective Date, FE will pay only for the costs of the temporary pension enhancement portion of any VERO offered (capped at $1,500 per month per employee until age 65 or a minimum of two years) in connection with such workforce reduction (for employees aged 58 by 12/31/2019). Any VERO can be offered in accordance with the above terms any time prior to the Plan Effective Date but after January 1, 2019.

Employee Pension Plans

•  Pension Bridge. In 2017 FE put in place a “Pension Bridge,” under which an employee between the age of 50 and 55 who is terminated only because the assets in his or her business unit were sold will have his or her pension bridged. FE will continue the Pension Bridge through December 31, 2020, and expand the Pension Bridge to cover employees between the age of 50 and 55 who are terminated only because the assets in his or her business unit were transferred. For the avoidance of doubt, an emergence from chapter 11 shall not alone constitute a termination of an employee. To the extent a plan amendment is required to effectuate the foregoing, no amendment to the pension plan shall be required if (i) otherwise prohibited by law or regulation or (ii) tax counsel to FE determines in its reasonable judgment such amendment would jeopardize the plan’s tax qualified status. In the event of (i) or (ii) in the preceding sentence, FE will continue the Pension Bridge through December 31, 2020, only for employees between the age of 50 and 55 who are terminated only because the assets in his or her business unit were sold.

Miscellaneous Employee Benefits

•  Health Care Runoff Claims. If the Debtors cease to participate in the Health Care Plans, FE and FESC will not charge the Debtors for any costs relating to the Health Care Plans with respect to employees and former employees of the Debtors from and after such date, including any amounts for incurred but not reported claims incurred up to and including the date that the Debtors ceased participation in the Health Care Plans (“Healthcare Runoff Costs”).
