6 completed pursuant to this Section 2.03 (Mechanics for Requesting Advances); and (B) all conditions precedent set forth in Section 5.04 (Advance Approval Conditions Precedent) in respect of the requested Advance have been satisfied (or waived in writing), then DOE shall issue to FFB an Advance Request Approval Notice no later than three (3) Business Days prior to the Requested Advance Date. (i) Funding. For any requested Advance for which an Advance Request Approval Notice has been issued pursuant to this Section 2.03(c) (Advance Funding) and for which no Drawstop Notice has been issued pursuant to Section 2.03(d) (Drawstop Notices), FFB shall fund such Advance on the Requested Advance Date in accordance with the FFB Note Purchase Agreement and the FFB Note.

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 one (1) Business Day following receipt thereof; and, provided further, that any amount required to be returned by the Borrower pursuant to this clause (ii) shall accrue interest at the Late Charge Rate from the date such Advance is made until 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, or the Collateral Agent as a result of such Advance withdrawal. (e) No Liability (m) 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 clauses (c)(i) and (c)(ii) above, 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

(n) 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 judgement. 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 entity 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.

(q) In no event shall the proceeds of the Advances be:

8 (v) applied towards any portion of Pre-Completion Costs incurred prior to the Eligibility Effective Date; (vi) used to pay interest payments on the Guaranteed Loan or programmatic fees charged by or paid to DOE relating to the Guaranteed Loan; (vii) disbursed to fund or reimburse the Borrower or any other Borrower Entity for any contribution made under the Base Funding Amount, except to the extent of proceeds constituting Eligible Project Cost Reimbursement Amounts; or (viii) used to pay any portion of the Pre-Completion Costs that are not Eligible Project Costs.

The entries made in the internal records maintained by or on behalf of DOE evidencing the amounts from time to time: (i) advanced by FFB under the FFB Note Purchase Agreement and the FFB Note; or (ii) paid by or on behalf of the Borrower from time to time in respect thereof, shall constitute, absent manifest error, evidence of the existence and amount of the FFB Note Obligations of the Borrower as therein recorded. Section 3.04 Interest Provisions Relating to All Advances. (a) Interest Amount and Interest Computations. (a) Interest shall accrue on the outstanding principal amount of each Advance from the date such Advance is disbursed to the Borrower pursuant to the FFB Note Purchase Agreement and the FFB Note, to the date such Advance is due, in each case, at a rate per annum as specified in the FFB Note Purchase Agreement. Except as provided in clause (ii) below, interest accrued on the outstanding principal balance of each Advance shall be due and payable to FFB on

10 each Payment Date beginning on the First Interest Payment Date to occur after the date on which such Advance is made, through and including the Maturity Date. (b) For each Advance made prior to the First Principal Payment Date, the amount of accrued interest on the FFB Note that would otherwise be due and payable on each Payment Date to occur until the date immediately prior to the First Principal Payment Date shall be capitalized in arrears on the respective Payment Date and be added to the principal amount due under the FFB Note, and interest shall accrue on the sum of the outstanding principal (including such capitalized interest) at the rate established for such Advance in accordance with paragraph 6 of the FFB Note; provided that the aggregate amount of accrued interest that may be capitalized shall not exceed the Maximum Capitalized Interest Amount and shall not cause the outstanding aggregate amount under the FFB Note to exceed the Maximum Guaranteed Loan Amount. The amount of interest that shall be capitalized on each Advance shall be determined as set forth in the FFB Note. (c) Without limiting the foregoing, all Overdue Amounts on the Guaranteed Loan shall: (A) accrue interest at the Late Charge Rate; and (B) be payable by the Borrower in accordance with the FFB Documents. (d) Any interest accrued on the FFB Note in excess of the Maximum Capitalized Interest Amount shall be payable by the Borrower in cash in arrears on each applicable Payment Date as provided in the FFB Note.

The Borrower acknowledges and agrees that all computations of interest and the Prepayment Price by FFB pursuant to this Section 3.04 (Interest Provisions Relating to All Advances) and the FFB Note shall, in the absence of manifest error, be evidence of the amount thereof. All computations of interest shall be made as set forth in the relevant FFB Document. (b) Interest Payment Dates. Subject to the terms of the FFB Note Purchase Agreement and the FFB Note, the Borrower shall pay accrued interest on the outstanding principal amount of each Advance: (i) on each Payment Date, as and to the extent specified in clause (a) above; (ii) on each prepayment date (to the extent thereof); and (iii) at maturity (whether by acceleration or otherwise). Section 3.05 Prepayments. (a) Terms of All Prepayments. (f) With respect to any prepayment of any Advance, whether such prepayment is voluntary or mandatory, including a prepayment upon acceleration, the Borrower shall comply with all applicable terms and provisions of this Agreement and the FFB Documents. All prepayment amounts shall be applied solely to the Guaranteed Loan or, where applicable as specified herein, to the Guaranteed Loan and the Cerberus Loan, Ratably, and may not be applied to prepayments of any other Permitted Indebtedness. (g) The Borrower may not re-borrow the principal amount of any Advance that is prepaid, nor shall any such prepayment create availability for further borrowings during the Availability Period.

11 (h) Simultaneously with all prepayments of the Advances under the Guaranteed Loan, whether voluntary or mandatory, the Borrower shall pay all accrued interest and other fees, costs, expenses and other Secured Obligations then outstanding under the Financing Documents. Any prepayments of the Advances under the Guaranteed Loan in full shall require payment in full of all other Secured Obligations. (i) If the Borrower fails to make a prepayment to FFB on any Intended Prepayment Date in accordance with this Agreement and the FFB Note, the Borrower shall pay FFB a Late Charge on any Overdue Amount from such Intended Prepayment Date to the date on which payment is made, computed in accordance with the provisions of the FFB Note. (j) Any prepayment made pursuant to this Section 3.05 (Prepayments) shall be : (A) applied on a pro rata basis to each Tranche (except as otherwise agreed by DOE and the Borrower); provided that prepayment proceeds received in connection with a specific Line pursuant to clause (B), (D), (E), (I), (J), (K), or (M) of Section 3.05(c)(i) (Mandatory Prepayments) shall be applied solely to the Relevant Tranche; (B) applied to the specific Advances identified by the Borrower in accordance with the FFB Documents and specified in the relevant Prepayment Election Notice, which notice shall specify if the prepayment is voluntary or mandatory; (C) applied in the inverse order of maturity among the outstanding principal amounts of such Advances; and (D) due in an amount equal to the Prepayment Price calculated by FFB in accordance with the terms of the FFB Note. (k) Any prepayment pursuant to this Section 3.05 (Prepayments) shall be due in an amount equal to the Prepayment Price determined in accordance with the terms of the FFB Note and on the Intended Prepayment Date specified in the relevant Prepayment Election Notice (it being understood that FFB’s calculation of the Prepayment Price of the FFB Note and/or any components thereof shall, in the absence of manifest error, be determinative and binding). (l) In the event of any prepayment in full of all outstanding Advances under a Tranche pursuant to this Section 3.05 (Prepayments), on or prior to the last day of the Availability Period, the remaining Guaranteed Loan Commitment Amount for such Tranche shall be deemed to be reduced to zero Dollars ($0), unless otherwise agreed to by DOE. (b) Voluntary Prepayments. (m) Subject to clause (ii) below, the Borrower may at any time, and from time to time, prepay all or any portion of the outstanding principal amount of any Advance under the FFB Note, upon prior submission of a Prepayment Election Notice by the Borrower to DOE and FFB (with a copy to the Collateral Agent) not less than ten (10) Business Days or, for a prepayment in full, thirteen (13) Business Days prior to the Intended Prepayment Date in accordance with the terms hereof and the FFB Note. (n) The Advances may only be prepaid under clause (i) above if either such prepayment includes prepayment in full of all outstanding Advances and all other Secured Obligations under all Tranches, or if in part as follows: (i) to the extent that such prepayment is made prior to the expiration of the Availability Period for the Relevant Tranche, (1) such prepayment includes prepayment in full of all outstanding Advances and all other FFB Note Obligations with respect to such Tranche, or (2) such prepayment includes a partial prepayment of the outstanding Advances and other FFB Note Obligations with respect to such Tranche;

12 provided that DOE has provided its prior written consent and the remaining Guaranteed Loan Commitment Amount is reduced to zero (0); or (ii) to the extent such prepayment is made after the expiration of the Availability Period for the Relevant Tranche, the Borrower has demonstrated to the satisfaction of DOE that, immediately following such prepayment: (i) each Reserve Account has been fully funded to its required balance in accordance with the Accounts Agreement; (ii) if the Line Commercial Operation Date of the Relevant Line has not yet occurred, the Line Commercial Operation Date of such Relevant Line is expected to occur on or before the corresponding Line Commercial Operation Longstop Date, and the total funding committed and available to the Borrower for such Line is sufficient to pay all remaining Pre-Completion Costs related to construction of such Line in accordance with the then-applicable Project Budgets and Plans and Base Case Financial Model; and (iii) the total funding available to the Project is sufficient to pay all O&M Expenses in accordance with the then-applicable Annual Plan and Base Case Financial Model, in each case, no Default or Event of Default has occurred, is continuing or could reasonably be expected to occur as a result of such prepayment.
