Form of Credit Agreement

CREDIT AGREEMENT

May 1, 2026

FOR VALUE RECEIVED, the undersigned AEMETIS BIOGAS LLC, a Delaware limited liability company (the “Borrower”), promises to pay to the order of THIRD EYE CAPITAL CORPORATION, an Ontario Corporation, as administrative agent and collateral agent (together with its successors and assigns, the “Agent”) for and on behalf of PROTAIR-X TECHNOLOGIES INC. (including its successors and assigns, the “Lender”), at its offices or such other place as the Agent may designate in writing the amounts that may be outstanding from time to time hereunder pursuant to the term loan facility (the “Facility”), as indicated pursuant to the records of the Agent with respect to such amounts, together with interest on the amount remaining unpaid from time to time from the date of this credit agreement (“Credit Agreement”) until due and payable, at the Interest Rate (defined below), as more particularly set out in Section 3 hereto. The Lender’s obligation hereunder shall be limited to the maximum commitment equal to $114,729,896.97, to be drawn in a single advance on the date hereof. All references to “$” or “dollars” is to the lawful currency of the United States and all capitalized terms shall have the definitions indicated herein or in Section 19(h) below.

Use of Proceeds. The Borrower shall use the proceeds of the advance made under the Facility on the date hereof to repurchase for cancellation 100% of those Series A Preferred Shares issued by the Borrower pursuant to that Series A Preferred Unit Purchase Agreement dated December 20, 2018 between the Borrower, the Lender and Third Eye Capital Corporation, as agent thereunder (as may be amended from time to time, the “PUPA”).

Repayments. The full outstanding principal balance of the indebtedness evidenced hereby under the Facility, together with all accrued but then unpaid and compounded interest thereon and any other sums due hereunder, shall be due and payable in full at the earlier to occur of: (i) May 1, 2027 (the “Maturity Date”), and (ii) the occurrence of an Event of Default.

Interest.

The outstanding principal under the Facility shall bear interest at a per annum rate equal to the greater of (i) the Prime Rate plus 10.0% and (ii) 16.0%, compounded daily in arrears (the “Interest Rate”).

If an Event of Default shall have occurred, all outstanding principal of and, to the fullest extent permitted by law, all past due interest and any other past due amounts owing under the Facility shall bear interest at a rate per annum equal to the Interest Rate plus ten percent (10%) per annum (the “Default Rate”). Interest payable at the Default Rate shall be payable from time to time on demand.

Interest shall be payable on the outstanding obligations in arrears for the preceding calendar month on the first Business Day of each calendar month. For greater certainty, interest on the unpaid principal balance shall accrue from the date hereof.

So long as no Event of Default has occurred and is continuing, on each applicable monthly interest payment date, subject to Section 4 hereto, up to 100% of the amount of interest then owing on the Facility may be capitalized to the principal amount outstanding, at the Borrower’s option.

Mandatory Repayments. Within 5 days of the last day of March, June, September and December of each calendar year, the Borrower shall repay to the Facility all of that amount (if positive) which is equal to one hundred percent (100%) of Free Cash Flow (as defined below) which it or any of its subsidiaries receives during the applicable preceding calendar quarter. Mandatory repayments pursuant to this Section 4 shall be made in immediately available funds.

Prepayments. The Borrower may, at any time and from time to time, prepay the indebtedness in whole under the Facility without premium or penalty, but with accrued and compounded interest to the date of such prepayment on the amount prepaid. Any notice of optional prepayment is irrevocable and shall be effective only if received by the Agent by 2:00 p.m. (Toronto, Ontario time) on the date that is five (5) Business Days prior to the proposed prepayment. Any notice of optional prepayment shall specify the amount to be prepaid and the date of prepayment.

Record Keeping. All borrowings and all payments made on account of the principal hereof shall be endorsed by the Agent in its internal records and shall be made a part hereof, provided however that any failure to endorse such information shall not in any manner affect the obligation of the Borrower to make payments of principal and interest in accordance with the terms hereof. All notations on such Agent’s internal records as to borrowings and repayments made shall constitute conclusive evidence of such borrowings or repayments.

Increased Costs. If, due to either (i) the introduction of or any change (including, without limitation, any change by way of imposition or increase of reserve requirements but excluding the imposition of, or any change in the rate of, any income tax payable by the Agent or any Lender) in or in the interpretation of any law or regulation or (ii) the compliance by the Agent or any Lender with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to the Agent of funding or maintaining the loans or obligations under this Credit Agreement, then the Borrower shall from time to time, upon demand by the Agent, pay to the Agent and/or the Lenders additional amounts sufficient to indemnify the Agent and the Lenders against such increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower by the Agent, shall be conclusive and binding for all purposes, absent manifest error.

Illegality. Notwithstanding any other provision hereof, if, in the reasonable opinion of the Agent, it becomes unlawful for a Lender to make or maintain its loan hereunder, then such Lender will promptly so notify the Borrower and the other Lenders and the Borrower will promptly prepay the balance in full together with accrued interest thereon and all other amounts then due and Lenders will have no further obligation to make or maintain the loan hereunder.

Payments and Computations.

The Borrower shall make each payment hereunder not later than 2:00 p.m. (Toronto, Ontario time) on the day when due to the Agent at its address referred to in Section 19(g) or at such other location as may be specified by the Agent to the Borrower, in immediately available funds without setoff, compensation, counterclaim, recoupment or other defense. Any payments received after 2:00 p.m. (Toronto time) will be considered for all purposes as having been made on the next following Business Day.

Agent and Lenders will maintain in accordance with their usual practice one or more accounts evidencing the indebtedness of the Borrower to the Agent hereunder. Such account(s) will be prima facie evidence of the obligations recorded therein, provided that any failure by Agent to maintain any account or any error therein shall not affect the obligation of the Borrower to repay its indebtedness to the Agent in accordance with this Credit Agreement.

Each determination of a rate of interest or fee by Agent will be conclusive evidence of such rate or fee in the absence of manifest error. Interest and fees will be calculated on the basis of a year of 365 days for the actual number of days (including the first day but excluding the last day) elapsed in the period for which such interest or fees are payable. For the purposes of disclosure pursuant to the Interest Act (Canada) and not for any other purpose, where in this Credit Agreement a rate is to be calculated on the basis of a year of 365 days, the yearly rate to which the 365-day rate is equivalent is such rate multiplied by the number of days in the year for which such calculation is made and divided by 365.

Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest.

10.

Taxes. The Borrower agrees that all payments to be made by it hereunder and the other Loan Documents shall be made without setoff, compensation or counterclaim and free and clear of, and without deduction for, any taxes, levies, imposts, duties, charges, fees, deductions, withholdings or restrictions or conditions of any nature whatsoever now or hereafter imposed, levied, collected, withheld or assessed by any country or by any political subdivision or taxing authority thereof or therein (“Taxes”). If any Taxes are required to be withheld from any amounts payable to the Agent hereunder, the amounts so payable to the Agent shall be increased to the extent necessary to yield to the Agent (after payment of all Taxes) the amounts payable hereunder in the full amounts so to be paid. Whenever any Tax is paid by the Borrower, as promptly as possible thereafter, the Borrower shall send the Agent an official receipt showing payment thereof, together with such additional documentary evidence as may be required from time to time by the Agent.

11.

Maximum Interest Rate. Notwithstanding any other provisions hereof or any other Loan Document: (i) in no event shall the aggregate “interest” payable to Agent and Lenders hereunder or the other Loan Documents exceed the effective annual rate of interest legally permitted under any Law in any relevant jurisdiction; and (ii) if any provision of this Credit Agreement or any other Loan Document would obligate the Borrower to make any payment of interest or other amount payable to Agent and Lenders in an amount or calculated at a rate which would be prohibited by Law or would result in a receipt by Agent or any Lender of interest at a criminal rate, then notwithstanding such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by Law or so result in a receipt by Agent or any Lender of interest at a criminal rate, such adjustment to be effected, to the extent necessary, as follows: (A) first, by reducing on a pro rata basis the amount or rates of interest required to be paid under Section 3 hereof, and (B) thereafter, by reducing any fees, commissions, premiums and other amounts which would constitute interest for purposes of any Law.

12.

Application of Payments. Prior to the occurrence of an Event of Default, all amounts received by the Agent or the Lenders from the Borrower in respect hereof shall be applied pro tanto to the obligations hereunder as follows: first, to pay any fees, indemnities or expense reimbursements then due to the Agent and the Lenders under the Loan Documents, until paid in full, second, to pay interest due, and third, to pay or prepay the principal amount and all outstanding obligations hereunder until paid in full. Upon the occurrence and during the continuance of an Event of Default, all amounts received by the Agent from the Borrower or any other Person shall be applied pro tanto to the obligations hereunder in such manner as the Agent shall determine in its sole discretion.

13.
