Form 6342 (5-2021) FIFTH AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT This Fifth Amendment to Amended and Restated Credit Agreement (“Amendment”) is made and entered into effective the 27th day of September, 2023, by and between Dakota Ethanol, L.L.C., a South Dakota limited liability company (“Borrower”) and Farm Credit Services of America, PCA and Farm Credit Services of America, FLCA, (each and collectively “Lender”) to amend and modify the Amended and Restated Credit Agreement dated February 2, 2018, (hereinafter referred to as the “Credit Agreement”). The Credit Agreement and underlying Loan Documents are modified only to the extent necessary to give effect to the terms of this Amendment, and the remaining terms of said Loan Documents, not otherwise inconsistent herewith, are ratified by the parties. Capitalized terms used but not otherwise defined herein have the respective meanings given to them in the Credit Agreement. In consideration of the mutual agreements, provisions and covenants herein contained, and furthermore to induce Lender to consider financial accommodations for the Borrower under the terms and provisions of the Credit Agreement, the parties hereby agree as follows: 1. Section 6.15 Borrowing Base is hereby removed from the Credit Agreement but reserved for future use. 2. Schedule 7.8 is hereby replaced by the attached Schedule 7.8. 3. The following sections are hereby amended to read as follows: Section 2.1.1 Loan Facility A (304761-069993-214088). Lender agrees to advance sums to Borrower up to the aggregate amount of $20,000,000.00 (Maximum Principal Balance) until November 1, 2025 (Final Advancement Date). Each Advance made will reduce the funds available for future advances by the amount of the Advance. Repayments of principal will be available for subsequent Advances. The commitment under said Loan will be used by Borrower for financing the operating needs of the company and Borrower agrees not to request or use such proceeds for any other purpose. To the extent Lender must make Protective Advances that would cause Loan Facility A to exceed the Maximum Principal Balance, the Maximum Principal Balance shall be deemed increased in order to include any and all Protective Advances. Any Protective Advances shall be due and payable upon demand and shall draw interest at the Default Rate. (a) Interest. Borrower hereby promises to pay interest on the principal indebtedness outstanding from time to time on each Advance from and including the date of such Advance and otherwise in accordance with statements issued by Lender. Interest shall be payable on the following dates, provided that interest accruing at the Default Rate, if applicable, shall be payable on demand. Interest shall be payable on the 1st day of each month continuing on October 1, 2023 at the following rate. Interest Rate. Interest shall accrue from the date of each Advance at a variable rate per annum equivalent to the CME 1- Month Term SOFR Reference Rate plus 3.0%. The interest rate shall be adjusted higher or lower on the 15th day of every month thereafter to reflect any change in the CME 1-Month Term SOFR Reference Rate for the prior month, and this higher or lower rate will thereafter apply to the outstanding principal indebtedness and remain in effect until a different rate of interest is established. The amount of any subsequent payments will be increased or decreased accordingly to reflect the different rate of interest without in any manner changing the due date of the payments. There is no limitation on the amount of the change in the interest rate. CME 1-Month Term SOFR Reference Rate is determined on the last day of each month by referencing an 'Index' known as the 1-Month CME Term SOFR (Secured Overnight Financing Rate) Reference Rate. The Index is currently published by the CME Group at https://www.cmegroup.com/market-data/cme-group-benchmark-administration/term-sofr.html. In the event an Index or reference rate is used to calculate the applicable interest rate, then, in no event shall the Index or reference rate used to determine the applicable interest rate be less than zero percent (0.00%), regardless of the actual published Index or reference rate. If such Index or reference rate is no longer available for any reason, is no longer posted through electronic transmission or through a source providing such information, or the Lender determines that the Index is unreliable or no longer adequately covers Lender's costs of making loans using this index, Lender will select a replacement index in its sole discretion which Index may be based upon comparable information and may include interest rate spread and adjustment thereto or other price adjustments to compensate Lender for costs incurred in making or maintaining the loan. (b) Principal. Borrower hereby promises to pay principal, plus all accrued interest and any unpaid fees, costs or expenses in full on November 1, 2025 ('Maturity Date').

If the outstanding principal balance is at or below the Maximum Principal Balance (taking into consideration any reductions in commitment)(“Applicable Maximum Balance”) up to and including the Final Advancement Date, Borrower will be billed interest only; if the outstanding principal balance exceeds the Applicable Maximum Principal Balance, Borrower will make principal payments in such amount as necessary to reduce principal to the Applicable Maximum Principal Balance available at that time.
