Seller and Buyer each may be referred to hereinafter individually as a “Party” or collectively as the “Parties.” WHEREAS, Buyer desires to engage Seller to perform detailed engineering, procurement, and construction in connection with Buyer’s acquisition of Seller’s proprietary, patented and/or patent- pending technologies referred to as Advanced Processing Package™ (APP™), which consists of the following ICM technologies: Selective Milling Technology™ (SMT™), Fiber Separation Technology Next Gen™ (FST Next Gen™), Thin Stillage Solids Separation System™ Phase 1 (TS4™ Phase 1), Feed Optimization Technology™ (FOT™), and Distillation Vacuum Technology™ (DVT™) (hereinafter, the “System”) at Buyer’s ethanol production facility located at 1554 North 600 East; Union City, IN 47390 (“Plant”); and WHEREAS, Seller desires and agrees to provide the goods and services described in this Agreement on the terms and conditions stated herein. For and in consideration of the mutual promises, covenants, agreements, and payments set forth herein, the sufficiency of which is hereby acknowledged, Seller and Buyer agree as follows: 1. Sale of Goods and Services. Subject to the terms and conditions specified herein, Seller will sell to Buyer, and Buyer will purchase from Seller the following: (A) The equipment described in Exhibit A to this Agreement (“Equipment”); (B) The services described in Exhibit B to this Agreement (“Services”); The operation of the System is subject to the License Agreement described in Paragraph 5 below and in Exhibit C to this Agreement.

Page 2 sizing of Equipment or integration of Equipment in a manner different than that designed by Seller shall require a Change Order that may also result in the increase of the Purchase Price. 2. Installation. (A) Location and Services. Seller will install the System at Buyer's Plant. The installation services to be provided by Seller are set forth in Exhibit B. Preliminary general arrangement drawing showing the proposed location of the installation of the System at the Plant is set forth in Exhibit D. Seller will install all Equipment in a workmanlike manner and in compliance with applicable laws, regulations, and ordinances in effect as of the date of this Agreement. (B) Schedule. Seller estimates that Substantial Completion for the installation of the System will occur approximately five hundred (500) days from the later of the date this Agreement is fully executed or Seller’s receipt of the payment listed in Section 3.B.a. Installation with Seller’s personnel will begin on an agreed upon date within two hundred (200) days of the date this Agreement is fully executed. The Parties acknowledge that completion of portions of the Work will require the Plant to shut down in whole or in part. Seller will use its best efforts to minimize the length and severity of the disruptions to Plant operations during installation. Seller will arrange its Work that requires the Plant to shut down to coincide with Buyer’s scheduled shutdowns. Seller’s installation will require at least fourteen (14) days of the Plant being completely shut down in durations and during dates negotiated and agreed to by both Parties. In addition, Buyer will be required to shut down sections of the Plant from time to time during the completion of the Work to facilitate tie-ins and safe construction. Seller will use its best efforts to minimize the length of partial operations shut-downs at the Plant while making the mechanical, electrical, and structural tie-ins required for the Work, and while installing major Equipment components. The tie-ins will be scheduled in advance and coordinated between the Parties. In the event Buyer fails to timely obtain applicable governmental permitting, including without limitation, the amended air permit, the Parties will mutually agree on a new date to begin the installation services. Buyer will make the Plant available to Seller during the term of this Agreement so that Seller can efficiently complete the Work. (C) Certificates. Upon the completion of installation of the Equipment at the Plant, Seller will issue a “Certificate of Substantial Completion.” Seller will commission/start-up the Equipment once it receives Buyer’s countersignature on the Certificate of Substantial Completion and the payment listed in Section 3.B.f. Following commissioning, Buyer and Seller will agree upon a “Punch List,” which identifies items or tasks to complete Seller’s Scope of Work. Seller will complete the Punch List within a reasonable period of time. When the Punch List has been completed, Seller and Buyer will sign a “Certificate of Final Completion” and the final milestone payment in Section 3(B) will be made to Seller. Upon satisfaction of a successful “Demonstration Test” as defined in Exhibit F, Seller and Buyer will sign a “Certificate of Successful Demonstration Test.” Forms of Seller’s certificates are attached as Exhibit E. (D) Permit. At least twenty-eight (28) days before Seller’s scheduled mobilization to the Plant to perform installation, Buyer will provide written notice to Seller that Buyer has

If written notice is not provided to Seller, the schedule will be adjusted as agreed by the Parties. 3. Purchase Price; Payments. (A) Purchase Price. The price that Buyer will pay to Seller for the Scope of Work identified herein is Forty-Five Million, Three Hundred Ninety Thousand and 00/100 U.S. Dollars ($45,390,000.00 USD) (“Purchase Price”). The Purchase Price is comprised of detailed engineering, procurement, and construction for the System and applicable Indiana state and local Sales Tax. The Purchase Price includes the cost of shipping Equipment to the Plant. The Purchase Price may be adjusted by written Change Order signed by the Parties. (B) Payment Schedule. The payment schedule is set forth in Exhibit J, which is a confidential exhibit that is not to be included in any public filing of this Agreement. (C) Price Adjustment for Market Volatility. The Purchase Price was calculated based on market prices for materials as determined on October 29, 2021, plus applicable surcharges. However, the market for some of the materials that are specified in this Agreement is volatile, and sudden price increases may occur. Seller agrees to use its best efforts to obtain advantageous prices from subcontractors and material suppliers. In the event of price increases of materials occurring during the performance of the Agreement through no fault of Seller, Seller will provide written notice to Buyer stating the increased cost, the materials at issue, and the source of supply, supported by price quotations, invoices or bills of sale. The Parties agree that up until thirty (30) days prior to Seller’s mobilization to the Plant Seller may request reasonable Purchase Price increases due to market volatility or material shortages through a Change Order, which Buyer may agree to pay said Purchase Price increase to Seller in Buyer’s discretion. In the event that Buyer declines to pay such Purchase Price increase, Seller may terminate this Agreement for convenience. (D) Seismic Consideration. The Purchase Price established in paragraph 3(A) of this Agreement accounts for Seismic Design Category A or B design considerations. (E) Private, Public, Bond or Grant Funding; Buyer’s Representations; Seller Change Order for Increased Costs. In the event Buyer takes any action (“Action”), including but not limited to, making application for or accepting private, public, bond or grant funding, executing a project Labor Agreement or other form of pre-hire or negotiated agreement with any crafts and trades that potentially creates special wage and/or benefit, schedule, work rules, hiring, retention, project payment documentation or other substantive requirements that affect the administration of the project or the labor pool engaged by Seller or Seller’s subcontractors and/or suppliers (the “Special Requirements”), Buyer will give Seller written notice of such Action no later than ten (10) days after taking such Action, and shall promptly provide Seller with all relevant information necessary for Seller to determine the impact to Seller and/or its subcontractors and/or suppliers of such Action. In all respects, Seller shall be entitled to a written change order executed by both

Buyer expressly represents to Seller that Seller will not be required to comply with any local, state, federal or other wage payment requirement including, but not limited to, prevailing wage regulations, Davis-Bacon Act, collective bargaining or other similar wage requirements ("Wage Requirements"). Notwithstanding the foregoing, and for the avoidance of doubt, Buyer acknowledges and agrees that it intends to fully perform its duties and all obligations set forth herein. Buyer acknowledges that the Purchase Price for Seller's Scope does not include the cost for Seller, its subcontractors, or suppliers at any level to comply with any Special or Wage Requirements. Buyer agrees to indemnify and hold Seller, its subcontractors and suppliers harmless from any claim that Seller's Scope is subject to Special or Wage Requirements. Buyer is obligated to execute a Change Order to cover all added expenses, including reasonable attorney fees incurred related to any applicable Special or Wage Requirements. Seller has materially relied upon Buyer’s representations concerning Special and Wage Requirements and that no surety bonding for the project is required, in its negotiation of the terms and conditions of this Agreement. If Buyer determines that changes are required to Seller’s Scope, and/or the terms and conditions set forth in this Agreement in order for Buyer to obtain any project funding, Buyer agrees to promptly negotiate in good faith with Seller and to execute a fixed price Change Order that fairly compensates Seller for its increased project costs related to the same. (F) [Not Used] (G) Payments. All amounts referenced in subparagraphs (A) and (B) are in United States Dollars and are to be paid in United States Dollars. Payments will be paid by wire transfer in accordance with the following wire transfer instructions: [SEE EXHIBIT J] (H) Interest.

(I) Tax. The Purchase Price includes applicable 7.00% Indiana sales tax on all building related materials, concrete, consumable items and rental equipment only. Seller will utilize Buyer’s Indiana sales tax certificate for all other items.

Seller will release its Security Interest at such time when Buyer makes payment in full of the Purchase Price (e.g., cumulative payments and credit(s) (if any) equal to the Purchase Price). Seller will file any necessary documents required to record such release of Seller’s Security Interest. (L) Lien Waivers. Seller shall obtain, at Seller’s expense, third party lien waivers for payments on invoices above $100,000.00 to third party contractors who perform work under this Agreement.

Procedure.
