This Guaranty amends and restates that certain Guaranty dated February 28, 2022 executed and delivered by the undersigned in favor of Lender, is continuation thereof, and is not a novation thereof. This Guaranty is issued and delivered as a condition to Lender’s extension of the Loans to the Debtor under the Loan Agreement. The undersigned agrees, on demand by Lender, to pay all sums guaranteed or due under this Guaranty regardless of any defense, right of set-off, or claims which the Debtor or the undersigned may have against Lender. This is an unlimited, absolute, irrevocable, present, and continuing guaranty of payment and performance, and not merely of collection and/or enforceability. Notwithstanding anything to the contrary contained in this Guaranty, in any action to enforce any of the obligations of the undersigned under this Guaranty, Lender, at its election, may proceed against the undersigned, with or without (i) joining the Debtor in any such action, (ii) commencing any action against or obtaining any judgment against the Debtor, (iii) commencing any action against or obtaining a judgment against any other guarantor, or (iv) commencing any proceeding to enforce the Liabilities, realize upon any Loan Document relating to the Liabilities, foreclose any Mortgage or Security Agreement securing any Liability or exercise any remedy contained therein, or obtain any judgment, decree, or foreclosure sale

Credit may be granted or continued from time to time by Lender to the Debtor without notice to or authorization from the undersigned regardless of the financial or other condition of the Debtor at the time of any such grant or continuation.

The undersigned is not in material default under any material agreement to which the undersigned is a party or otherwise bound; and (f) The undersigned has disclosed all material events, conditions and facts known to the undersigned which could have any material adverse effect on the financial condition of the undersigned or the Debtor or an adverse effect on any collateral for the Liabilities.

The undersigned will maintain in good standing its existence and its right to transact business in its State of incorporation and in each State in which it operates, and will continue to engage in the same lines of business in which it is presently engaged. The undersigned will permit the Lender and any agent of the Lender to visit and inspect any of its properties, corporate books, financial records, grain and inventory warehouses, and grain and ethanol and distiller's grains inventory records, and to discuss its affairs, finances and accounts with its principal officers and independent public accountants, all at such reasonable times and as often as the

Lender may reasonably request. At the request of Lender, the undersigned shall permit, and will cooperate with the Lender in arranging for, inspections from time to time of the undersigned’s facilities and audits of the Collateral (as defined in the Guarantor Security Agreement). The undersigned acknowledges that any reports and inspections conducted or generated by the Lender or its agents or representatives, shall be made for the sole benefit of the Lender and not for the benefit of the undersigned, the Debtor, or any third party, and the Lender does not assume any liability, responsibility or obligation to the undersigned, the Debtor, or any third party by reason of such inspections or reports. The reasonable costs and expenses of such audits and inspections made by the Lender shall be paid or reimbursed by the undersigned. The undersigned will comply in all material respects with all statutes, laws and governmental rules, regulations, Permits, and orders applicable to its business, properties, assets, and organization as an IC-DISC corporation under the Internal Revenue Code. The undersigned will promptly inform the Lender of the commencement of any material action, suit, proceeding, arbitration, mediation or investigation against the undersigned, or the making of any counterclaim against the undersigned, and of all material Liens against any of the undersigned’s property and promptly advise the Lender in writing of any other condition, event or act which comes to its attention that would or might materially prejudice Lender's rights under this Guaranty or the Loan Documents to which the undersigned is a party, or otherwise result in a Material Adverse Effect. Before proceeding under this Guaranty against the undersigned, resort need not be made by Lender to any other Collateral or security for any or all of the Liabilities whether pledged by the Debtor or by any other person in connection with the Liabilities, nor need Lender exhaust any remedy against the Debtor, nor against any other endorser, surety, or guarantor of the Liabilities. The undersigned shall pay on demand all reasonable costs of collection, legal expenses, and attorneys’ fees incurred or paid by Lender in collecting and/or enforcing this Guaranty, unless prohibited by applicable law. Until indefeasible payment in full of all Liabilities, the undersigned forever subordinates any right of subrogation against the Debtor on account of payment made pursuant to this Guaranty. The undersigned agrees that, if at any time all or any part of any payment previously applied by Lender on any of the Liabilities must be returned by Lender for any reason, whether by court order, administrative order, or settlement, the undersigned shall remain liable for the full amount returned as if such amount had never been received by Lender, notwithstanding any termination of this Guaranty or the cancellation of any agreement evidencing the Liabilities. The undersigned agrees that the obligations, covenants, and agreements of the undersigned under this Guaranty shall not be affected or impaired by any act of Lender, or any event or condition except full payment of the Liabilities and any other sums due under this Guaranty. The undersigned agrees that, without full payment of the Liabilities, the liability of the undersigned under this Guaranty shall not be discharged by (i) any assignment of the Liabilities by Lender, sale of participations in the Liabilities by Lender, transfer, waiver, compromise, settlement, modification, surrender, impairment, or release of any Liability or collateral for any Liability, (ii) the existence of any defenses to enforcement of any Liability or

any security therefor, (iii) any failure, omission, delay, or inadequacy, whether entire or partial, of Lender to exercise any right, power, or remedy regarding any Liability or to enforce or realize upon (or to make the undersigned a party to the enforcement or realization upon) any of Lender’s security for any Liability, including, but not limited to, any impairment or release of such security by Lender, (iv) the existence of any set-off, claim, reduction, or diminution of the Liabilities, or any defense of any kind or nature, which the undersigned may have against Lender, (v) the application of payments received from any source to the payment of any obligation other than the Liabilities, even though Lender might lawfully have elected to apply such payments to any part or all of the Liabilities, or (vi) the addition of any and all other endorsers, the undersigned, obligors, and other persons liable for the payment of the Liabilities and the acceptance of any and all other security for the payment of the Liabilities; all whether or not the undersigned has had notice or knowledge of any act or omission referred to in any of the foregoing clauses. Lender intends that the undersigned shall remain liable under this Guaranty as principal until all Liabilities have been indefeasibly paid in full, notwithstanding any fact, act, event, or occurrence which might otherwise operate as a legal or equitable discharge of a surety or guarantor. This Guaranty shall remain fully enforceable irrespective of any defense which the Debtor may assert on the Liabilities or against enforcement of this Guaranty, including but not limited to failure of consideration and statute of frauds. The undersigned further waives all errors and omissions in connection with Lender’s administration of the Liabilities and collateral for the Liabilities. A waiver by Lender of any right or remedy on any one or more occasions shall not be construed as a bar to or a waiver of any such right or remedy on future occasions. The undersigned agrees to provide to Lender any financial statements and information required in the Loan Agreement (which requirements are incorporated into this Guaranty by reference) at the times provided for therein and from time to time such further information regarding the financial condition, business, and/or properties of the undersigned as Lender may reasonably request. The undersigned authorizes Lender to obtain from time to time a credit report on the undersigned from any credit reporting agency or bureau. The undersigned has unconditionally delivered this Guaranty to Lender and failure to sign this or any other guaranty by any other person shall not discharge the liability of the undersigned under this Guaranty. This Guaranty shall be secured by all assets and/or collateral now or hereafter pledged by the undersigned to Lender to secure any Liabilities, including, but not limited to, the Collateral defined in and encumbered by that certain First Amended and Security Agreement of even date with this Guaranty executed in favor of and delivered by the undersigned to Lender, as it may be amended, supplemented, restated, refinanced, or otherwise modified from time to time. This Guaranty shall be governed by, and construed in accordance with, the laws of the State of Nebraska, exclusive of its choice of laws rules, shall inure to the benefit of Lender, its successors and assigns, and shall be binding upon the undersigned and the heirs, beneficiaries, successors, and assigns of the undersigned.

of this paragraph shall not be deemed to preclude Lender from filing any such action, suit, or proceeding in any other appropriate forum.
