PRELIMINARY STATEMENTS (A) DOE has been authorized to issue a guarantee for Federal Financing Bank (“FFB”), a wholly-owned instrumentality of the United States government created by the Federal Financing Bank Act of 1973, as amended, to make loans for the restart and repowering of the Christopher M. Crane Clean Energy Center (f/k/a Three Mile Island Nuclear Station, Unit 1), an 835 MW nuclear generating station located in Londonderry Township, Pennsylvania (the “Plant”), pursuant to Title XVII of the Energy Policy Act of 2005, Pub. L. 109-58, as amended by Pub. L. 117–169, title V, § 50144(c), and as further amended from time to time (“Title XVII”). (B) The Borrower has undertaken, or intends to undertake, the financing, licensing, permitting, development, design, engineering, procurement, restart, testing, startup and commissioning of the Plant (the “Project”). (C) The Borrower submitted an application for the issuance by DOE of a guarantee of a multi- draw term loan facility to be authorized and approved by DOE under Title XVII, subject to the requirements of Section 1706 and the Applicable Regulations. (D) The Borrower and DOE entered into that certain Conditional Commitment Letter, dated as of the date hereof (the “Conditional Commitment Letter”), pursuant to which DOE agreed to arrange for FFB to purchase the FFB Note from the Borrower and to make Advances from time to time thereunder, in each case, upon the terms and subject to the conditions of this Agreement and the other Financing Documents. (E) Subject to the terms and conditions hereof, DOE will, in connection with arranging financing for the Borrower from FFB, issue and deliver to FFB the DOE Guarantee pursuant to which it will guarantee the Borrower’s repayment of principal and interest on the Advances as and when required pursuant to the FFB Note and any other liabilities, losses, costs or expenses incurred by FFB from time to time with respect to the FFB Note or the related FFB Note Purchase Agreement. (F) The execution of this Agreement is a condition precedent to DOE’s issuance of the DOE Guarantee, and FFB’s receipt of the DOE Guarantee is a condition precedent to FFB’s execution of the FFB Documents. (G) The parties hereto desire (a) to specify, among other things, the terms and conditions for (i) the delivery by DOE of the DOE Guarantee and other FFB Secretary’s Instruments required for FFB to purchase the FFB Note pursuant to the FFB Note Purchase Agreement; (ii) the delivery by DOE of Advance Request Approval Notices; and (iii) certain indemnity

(ii) Consequences. If a Drawstop Notice is issued, FFB shall not be obligated to make the requested Advance set forth on such Drawstop Notice; provided, that if FFB makes any such Advance to the Borrower following the issuance of a Drawstop Notice, the Borrower shall return such Advance to FFB within five (5) Business Days following receipt thereof; and, provided further, that any amount required to be returned by the Borrower pursuant

7 [***] = Certain information has been excluded from this exhibit because it is both not material and the type that the registrant treats as private or confidential. to this clause (ii) shall accrue interest at the Late Charge Rate from the date such Advance is made until and including the date such Advance is returned and be subject to payment of a make-whole amount in accordance with the FFB Note. Following the return of such Advance, FFB shall deliver an invoice to the Borrower setting forth the interest and other applicable make-whole amount due and payable with respect to such returned amount. The Borrower shall pay promptly, but in no event later than five (5) Business Days following delivery of such invoice, such interest and other applicable make-whole amounts as directed by FFB, and the Borrower shall pay all costs and expenses incurred by DOE, FFB, and the Designated Agent (as applicable) as a result of such Advance made following the issuance of a Drawstop Notice. (c) No Liability. (i) The Borrower acknowledges and agrees that DOE shall only be required to use its reasonable efforts to provide FFB with the necessary Advance Request Approval Notices within the time frames specified in Section 2.04(a)(ii) (Advance Request Approval Notice) but DOE shall in any event ensure that FFB receives all such Advance Requests and Advance Request Approval Notices as soon as reasonably practicable following receipt from the Borrower of the applicable Advance Requests and certificates and other documentation specified above (subject to the Borrower satisfying all conditions precedent specified in this Agreement, including Section 5.03 (Advance Approval Conditions Precedent) and Section 5.04 (Conditions Precedent to FFB Advance), as applicable, and, prior to the Execution Date, Section 5.01 (Conditions Precedent to the Execution Date) and Section 5.02 (Conditions Precedent to FFB Purchase of the FFB Note), respectively). (ii) Neither DOE nor FFB shall have any liability for any action taken (including the delivery of a Drawstop Notice) or omitted to be taken (including the refusal to fund any Advance or Advances following the issuance of a Drawstop Notice) or for any loss or injury resulting from its actions or inaction or its performance or lack of performance of any of its other obligations hereunder unless and solely to the extent such liability arises from the gross negligence or willful misconduct of DOE or FFB as determined by a court of competent jurisdiction in a final, Non-Appealable judgment. In no event shall DOE, FFB or any subsequent holder of the FFB Note be liable, and each such Person shall be exempt from liability in accordance with Section 11.08 (Limitation on Liability), in each case: (A) for acting in accordance with, or relying upon, any entitlement order, instruction, notice, demand, certificate or document from the Borrower or any Person acting on behalf of the Borrower; or (B) in the case of FFB or any subsequent holder of the FFB Note, for acting in accordance with, or relying upon, any Drawstop Notice issued by DOE. (iii) Notwithstanding anything contained in this Agreement to the contrary, neither DOE nor FFB shall incur any liability to the Borrower, any Affiliate thereof or to any other Guaranteed Party for not performing any act or fulfilling any duty, obligation or responsibility hereunder or under any other Financing Document by reason of any Guaranteed Party Force Majeure Event; it being understood that DOE or FFB, as the case may be, shall resume performance hereunder as soon as reasonably practicable after the effects of such Guaranteed Party Force Majeure Event cease to prevent or otherwise hinder DOE or FFB, as applicable, from performing hereunder or thereunder.

(i) The Borrower shall apply the proceeds of any Advance solely to reimburse the Borrower for Eligible Project Costs previously incurred and either expended or accrued by the Borrower, as evidenced by accruals, invoices or other documentation delivered in connection with the applicable Advance Request under Section 2.03(a) (Advance Requests). (ii) In no event shall the proceeds of the Advances be: (A) applied towards any portion of the Project Costs incurred prior to the Eligibility Effective Date; (B) used to pay interest payments on the Guaranteed Loan or programmatic fees charged by or paid to DOE relating to the Guaranteed Loan; (C) used to pay any portion of the Project Costs that are not Permitted Costs at the time of the Advance Request; or (D) used to pay any portion of Project Costs that are not Eligible Project Costs. Section 2.05 Advance Requirements under the FFB Documents. Notwithstanding anything to the contrary contained in this Article II (Funding), the Borrower shall comply with each disbursement requirement set forth in the FFB Documents. Unless otherwise specified in the FFB Documents, all determinations to be made with respect to the FFB Documents shall be made by DOE. Section 2.06 No Approval of Work. The making of any Advance or Advances under the Financing Documents shall not be deemed an approval or acceptance by any Guaranteed Party of any work, labor, supplies, materials or equipment furnished or supplied with respect to the Project. Section 2.07 Determination of Advance Amounts. As of any date of any requested Advance, after giving effect to the Advance: (a) the aggregate outstanding principal amount of all Advances then made to the Borrower under the FFB Note (including, for the avoidance of doubt, the principal amount of such requested Advance) shall not exceed eighty percent (80%) of the amount of Eligible Project Costs incurred and either expended or accrued on or prior to the date of such requested Advance; and (b) the aggregate outstanding principal amount of all Advances shall not exceed the Guaranteed Loan Commitment Amount (collectively, clauses (a) and (b) are referred to as the “Debt Sizing Parameters”).
