FIRSTENERGY NUCLEAR GENERATION, LLC (formerly known as FirstEnergy Nuclear Generation Corp.), a limited liability company of the State of Ohio (herein, together with its successors and assigns, the “Company”), for value received promises to pay to FirstEnergy Corp., an Ohio corporation (the “Lender”), under that certain Credit Agreement, dated as of December 6, 2016, among FirstEnergy Solutions Corp., an Ohio corporation, as Borrower (the “Borrower”), the Company and FirstEnergy Generation, LLC, an Ohio limited liability company (“FG”), as Guarantors, and the Lender (such Credit Agreement, as amended from time to time, hereinafter the “Credit Agreement”), or permitted assigns, on December 31, 2018, the principal sum of [        ] Dollars or, at any time (if less), such lesser principal amount as is equal to the product of the Nuclear FMB Ratio and the aggregate of the sum of (a) the Outstanding Credits at such time, plus (b) the aggregate unpaid principal amount of all Reimbursement Obligations that are outstanding under the Credit Agreement at such time, and to pay interest on said principal amount from the date hereof at such rate or rates per annum on each day as shall cause the amount of interest payable on the Bonds of this series on an Interest Payment Date (as hereinafter defined) to equal the sum of the amount of accrued interest on such Outstanding Credits and outstanding Reimbursement Obligations plus the amount of accrued Surety Credit Support fees pursuant to Section 2.05 of the Credit Agreement payable on such Interest Payment Date; provided, however, that such interest rate or rates shall not exceed ten percent (10%) per annum (calculated on the basis of a year of 360 days for the actual days elapsed). Said interest shall accrue hereon until the principal hereof shall be paid in full, subject to Section 2.04 of the Sixth Supplemental Indenture dated as of December 19, 2016 (as amended, supplemented, modified or restated, the “Supplemental Indenture”), executed and delivered by the Company to the Trustee (as hereinafter defined), which provides for certain credits towards payment of principal of, and interest on, the Bonds of this series. Interest shall accrue on the Bonds of this series from the date of issuance hereof, and the payment thereof shall be credited as provided in Section 2.04(a) and (c) of the Supplemental Indenture unless and until the Trustee receives the notice contemplated by Section 2.04(b) or (d) of the Supplemental Indenture, whereupon the interest on the Bonds of this series shall become and remain due and payable until such time as the Trustee receives a further written notice (including a telecopy or other form of written telecommunication) from an Authorized Representative of the Lender stating that such payments need not continue. The interest on each Bond of this series so payable on any Interest Payment Date shall, subject to the exceptions provided in Section 3.07 of the Indenture (as hereinafter defined) and to the provisions of Section 2.04 of the Supplemental Indenture, be paid to the person in whose name such Bond is registered on the date of such payment. The principal of, and the interest on, this Bond shall be payable at the office or agency of the Company in the City of Cleveland, State of Ohio in any coin or currency of the United States of America which at the time of payment is legal tender for the payment of public and private debts.
As used herein, “Interest Payment Date” shall mean the applicable date for the payment of accrued interest on Outstanding Credits plus outstanding Reimbursement Obligations and accrued Surety Credit Support Fee under the Credit Agreement and the terms “Advances,” “Commitment,” “Guarantor,” “Note,” “Outstanding Credits,” “Reimbursement Obligation,” and “Surety Credit Support,” and “Surety Credit Support Cap” shall have the respective meanings set forth in the Credit Agreement.
This Bond is one of an issue of Bonds of the Company known as its First Mortgage Bonds, issued and to be issued in one or more series under and secured by an Open-End Mortgage, General Mortgage Indenture and Deed of Trust, dated as of June 1, 2009, duly executed by the Company to The Bank of New York Mellon Trust Company, N.A., a national banking association organized and existing under the laws of the United States of America, as Trustee (the “Trustee”), and indentures supplemental thereto, heretofore or hereafter executed, including the Sixth Supplemental Indenture dated as of December 19, 2016 (as amended, supplemented, modified or restated, the “Supplemental Indenture”), to which Open-End Mortgage, General Mortgage Indenture and Deed of Trust and all indentures supplemental thereto (collectively referred to as the “Indenture”) reference is hereby made for a description of the property mortgaged and pledged, the nature and extent of the security, the terms and conditions upon which such Bonds are, and are to be, issued and secured, and the rights of the owners of such Bonds and the Trustee in respect of such security.  As provided in the Indenture, such Bonds may be in various principal sums, are issuable in series, may mature at different times, may bear interest at different rates and may otherwise vary as therein provided; and this Bond is one Bond of a series entitled “First Mortgage Bonds, Collateral Series L of 2016 due 2018,” created by the Supplemental Indenture, as provided for in the Indenture, and authorized for issuance in an aggregate principal amount of up to $450,000,000.
Any payment of Advances and Reimbursement Obligations made by or on behalf of the Borrower in respect of the Credit Agreement shall be deemed a payment in respect of this Bond, but such payment shall not reduce the principal amount of this Bond then in effect unless the amount available to be advanced under the Commitment is irrevocably reduced concurrently with such payment pursuant to a Voluntary Commitment Reduction or a Mandatory Commitment Reduction or an irrevocable reduction to the Surety Credit Support Cap. The obligation of the Borrower to make payments with respect to the principal of and interest on the bonds of December 2016 Collateral Series shall be fully satisfied and discharged to the extent that, at any time that any such payment shall be due, the Borrower shall have paid fully all the Outstanding Credits and Reimbursement Obligations, and the Commitments shall have been terminated. In the event that all of the Borrower’s obligations under the Credit Agreement have been discharged and the Note shall have been cancelled, this Bond shall be deemed paid in full and the Holder shall surrender this Bond to the Trustee for cancellation.
The Bonds of this series shall be redeemed promptly, without notice, by the Company in whole at 100% of the principal amount thereof plus accrued interest to the date of redemption (the “Redemption Price”) following receipt by the Trustee of written demand for redemption (a “Redemption Demand”) from an Authorized Representative of the Lender under the Credit Agreement stating that (i) all of the Advances or Reimbursement Obligations under the Credit Agreement have become or have been declared to be immediately due and payable as a result of the occurrence and continuance of an “Event of Default” under the Credit Agreement and (ii) that the Lender has demanded payment thereof from the Borrower; provided that the Bonds of this series shall be redeemed automatically by the Company, without notice (other than to the Trustee), in whole at the Redemption Price, if the Advances and Reimbursement Obligations under the Credit Agreement have become immediately due and payable as a result of the occurrence of an “Event of Default” under the Credit Agreement with respect to the Borrower or any Subsidiaries (as defined in the Credit Agreement) under Section 6.01(f) of the Credit Agreement. Such redemption shall be effected on the fifth Business Day (a) following receipt by the Trustee of the Redemption Demand, if such Redemption Demand is required, or (b) the occurrence of an “Event of Default” under the Credit Agreement with respect to the Borrower or any Subsidiaries (as defined in the Credit Agreement) under Section 6.01(f) of the Credit Agreement. Any payment of the Redemption Price made to the Lender shall constitute a payment by the Borrower in respect of the Outstanding Credits and the Reimbursement Obligations under the Credit Agreement. A Redemption Demand shall be rescinded and shall be null and void for all purposes of the Indenture upon receipt by the Trustee, no later than the Business Day prior to the date fixed for redemption, of a written notice from the Lender withdrawing said Redemption Demand.
For the avoidance of doubt, in accordance with Section 2.19 of the Credit Agreement, the Holder acknowledges that the obligations of the Borrower, each Guarantor party thereto, including the Company and FG, under the Credit Agreement and any Loan Document defined therein shall not constitute “FES Indebtedness” or “Genco Indebtedness” for purposes of Section 2 of each of the 2007 Guaranties (defined herein). Accordingly, the Holder acknowledges that the obligations of the Company under this Bond shall not constitute “FES Indebtedness” or “Genco Indebtedness” as defined in Section 2 of each of the 2007 Guaranties, and shall not be entitled to the benefits of any of the 2007 Guaranties.  The acknowledgments, representations and agreements in this paragraph are those of the Holder alone and not the Trustee.
