(d) All-in Rate. The all-in interest rate on the Loan shall be Term SOFR (subject to the SOFR Floor) plus 2.85% per annum.

(e) Default Rate. Upon the occurrence and during the continuance of any Event of Default, the outstanding principal balance of the Loan, and to the extent permitted by applicable law, all accrued but unpaid interest and any other amounts due and payable under the Loan Documents, shall bear interest at the Default Rate, which shall be a rate per annum equal to two percent (2.00%) above the rate of interest otherwise applicable to the Loan at such time. The Default Rate shall apply automatically upon the occurrence of an Event of Default described in Section 9.1(e) (Bankruptcy/Insolvency) and, in the case of all other Events of Default, upon written notice from the Administrative Agent to the Borrower.

(f) Computation of Interest. All interest shall be computed on the basis of a 360-day year and charged for the actual number of days elapsed (including the first day but excluding the last day). Each determination of the applicable interest rate by the Administrative Agent shall be conclusive and binding, absent manifest error.

(g) Interest Payment Dates. Accrued interest on the Loan shall be payable monthly in arrears on the first Business Day of each calendar month, commencing on the first such date following the date of the first Advance, and on the Maturity Date (or Extended Maturity Date, if applicable).

Section 2.4 — Fees

(a) Arrangement Fee. The Borrower shall pay to the Administrative Agent, for the pro rata account of the Lenders, an arrangement fee in an amount equal to one percent (1.00%) of the Total Commitments, which equals Three Million Nine Hundred Thousand and No/100 Dollars ($3,900,000) ($390,000,000 × 1.00% = $3,900,000). The Arrangement Fee shall be fully earned and non-refundable upon payment and shall be payable on the Closing Date. The Arrangement Fee shall be allocated among the Lenders in accordance with their respective Commitment Percentages.

(b) Unused Commitment Fee. The Borrower shall pay to the Administrative Agent, for the pro rata account of the Lenders, an unused commitment fee equal to zero and 50/100 percent (0.50%) per annum on the daily average undrawn portion of the Total Commitments during each quarterly period. The Unused Commitment Fee shall be calculated on an actual/360 basis and shall be payable quarterly in arrears, commencing on the first quarterly date following the Closing Date (i.e., the first Business Day of the first full calendar quarter following the Closing Date), and continuing on the first Business Day of each subsequent calendar quarter and on the Maturity Date or, if the Commitments are terminated prior to the Maturity Date, on the date of such termination. For the avoidance of doubt, the Unused Commitment Fee shall cease to accrue on the earlier of (i) the date on which the Total Commitments are fully drawn and (ii) the termination of the Commitments.

(c) Administrative Agent Fee. The Borrower shall pay to the Administrative Agent, for its own account, an annual administrative fee in the amount separately agreed upon between the Borrower and the Administrative Agent. Such fee shall be payable annually in advance on the Closing Date and on each anniversary thereof during the term of the Loan.

Section 2.5 — Advances / Draw Procedures

(a) Draw Requests. The Borrower shall deliver a Draw Request to the Administrative Agent not less than five (5) Business Days prior to the requested Advance date. Each Draw Request shall be substantially in the form of Exhibit B attached hereto and shall be accompanied by the following:

(iv) an updated cost-to-complete analysis, in reasonable detail, demonstrating that the remaining funds available under the Loan and the remaining unfunded Equity Contribution (together with any contingency and reserves available under the Approved Budget) are sufficient to complete the construction of the Project in accordance with the Plans and Specifications and the Approved Budget;

(v) confirmation that, after giving effect to the requested Advance, the Loan-to-Cost Ratio will not exceed sixty-five percent (65%);

(vi) copies of all invoices, requisitions, and supporting documentation for the costs and expenses for which reimbursement or payment is sought;

(vii) a schedule of values and percentage of completion for each line item in the Approved Budget; and

(viii) such other information and documentation as the Administrative Agent may reasonably require.

(b) Construction Consultant Inspection. Prior to the funding of each Advance (other than the initial Advance), the Administrative Agent shall engage the Construction Consultant (Kestrel Infrastructure Advisors, LLC; Diane Prescott, Principal) to conduct an on-site inspection of the Project and to verify the progress of construction and the accuracy of the information set forth in the Draw Request. The Construction Consultant shall deliver a written report to the Administrative Agent confirming (i) the percentage of completion of the Project, (ii) the consistency of construction progress with the construction schedule and the Approved Budget, and (iii) the reasonableness of the amounts requested in the Draw Request. The costs and expenses of the Construction Consultant shall be borne by the Borrower.

(c) Disbursement. Upon satisfaction of the conditions set forth in this Section 2.5 and Section 4.2, the Administrative Agent shall notify the Lenders of the approved Advance amount and each Lender's pro rata share thereof. Each Lender shall fund its pro rata share of the Advance to the Administrative Agent, and the Administrative Agent shall disburse the proceeds of the Advance through the Title Company (Fidelitas Title & Escrow, Inc.) or directly to the EPC Contractor, as designated by the Borrower and approved by the Administrative Agent.

(d) Limitation on Advances. No Advance shall be made that would cause the aggregate outstanding principal amount of all Advances to exceed Three Hundred Ninety Million and No/100 Dollars ($390,000,000). Additionally, no Advance shall be made after the expiration of the Draw Period.

(e) Frequency. The Borrower may submit Draw Requests no more frequently than once per calendar month, unless otherwise agreed by the Administrative Agent.

Section 2.6 — Equity Contribution Requirements

(a) Minimum Equity Contribution. The Minimum Equity Contribution of Fifty-Two Million Five Hundred Thousand and No/100 Dollars ($52,500,000), representing twenty-five percent (25%) of the total Equity Contribution of Two Hundred Ten Million and No/100 Dollars ($210,000,000), must be funded by the Borrower and verified by the Administrative Agent prior to the first Advance. Evidence of the Minimum Equity Contribution shall include copies of bank statements, wire transfer confirmations, and a certification executed by the Guarantor confirming the amount and source of the equity funds.

(b) Pari Passu Funding. Following the funding of the Minimum Equity Contribution and the initial Advance, equity and Loan proceeds shall be drawn on a pari passu basis, or in such other proportions as the Administrative Agent may approve in its reasonable discretion, in each case maintaining the overall ratio of thirty-five percent (35%) equity to sixty-five percent (65%) debt as set forth in the Approved Budget and the capital stack set forth on Schedule 1.1(c). The Administrative Agent may, in its reasonable discretion, permit temporary deviations from the strict pari passu funding sequence, provided that the Borrower returns to compliance with the required equity-to-debt ratio within sixty (60) days.

(c) Evidence. The Borrower shall deliver to the Administrative Agent, concurrently with each Draw Request, a certification and supporting documentation demonstrating the cumulative equity contributions made to date and confirming that the required equity-to-debt funding proportions have been maintained.

Each partial prepayment shall be in a minimum principal amount of Five Million and No/100 Dollars ($5,000,000) and in integral multiples of One Million and No/100 Dollars ($1,000,000) in excess thereof. All voluntary prepayments shall be applied pro rata to the Lenders in accordance with their respective Commitment Percentages.

Upon the occurrence of a Change of Control of the Borrower or the Guarantor, the Borrower shall be required to prepay the Loan in full, together with all accrued and unpaid interest and all other amounts due under the Loan Documents, within thirty (30) days of such event. For purposes of this clause, a "Change of Control" is as defined in Section 1.1. The Borrower shall promptly notify the Administrative Agent in writing upon becoming aware of any event or circumstance that could reasonably be expected to constitute a Change of Control.

(ii) Casualty / Condemnation.
