NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein, the parties agree as follows:

ARTICLE I

PURCHASE AND SALE TERMS AND PROCEDURES

Section 1.01. Grain Supply and Procurement. Subject to the exceptions set forth in this Agreement, ▇▇▇▇▇▇▇▇ agrees to supply Aemetis Keyes and Aemetis Keyes agrees to procure from ▇▇▇▇▇▇▇▇ all of Aemetis ▇▇▇▇▇’▇ requirements for whole yellow corn (“Corn”) for the Ethanol Plant, as further described in Section 1.10 below. In no event will the aggregate amount of Corn required to be delivered to Aemetis Keyes within any four consecutive day period exceed [***]. From time to time, ▇▇▇▇▇▇▇▇ at its sole discretion also may enter into Sale Contracts with Aemetis Keyes for ▇▇▇▇/grain sorghum (“Milo”) in minimum amounts of [***]. Aemetis Keyes agrees that all of its purchases are intended for use at its Ethanol Plant, and any Grain which is purchased by Aemetis Keyes from ▇▇▇▇▇▇▇▇ that becomes excess due to changes in operating conditions will be offered first to [***].

Section 1.02. ▇▇▇▇▇▇▇▇ Offers. ▇▇▇▇▇▇▇▇ agrees that each day the Chicago Board of Trade (“CBOT”) is in operation ▇▇▇▇▇▇▇▇ will have offers for sale of Corn [***] to be delivered to Aemetis Keyes and that ▇▇▇▇▇▇▇▇ may make offers outside of the hours of operation of the CBOT. Sales Contracts for Milo will be on a CIF Keyes basis and upon such additional terms specified in such Sale Contracts. Aemetis Keyes may accept offers as and when it determines in its sole discretion. In accordance with National Grain and Feed Association Rules, an oral offer and acceptance will be converted to a written order and delivered to Aemetis Keyes as agreed upon between ▇▇▇▇▇▇▇▇ and Aemetis Keyes after Aemetis ▇▇▇▇▇’▇ oral acceptance of each offer. The offer price of Grain to Aemetis Keyes will be based on the [***].

Section 1.03. Alternate Sources. The parties agree that Aemetis Keyes may source Corn from other suppliers subject to the following conditions:

(a) Direct Sourced Rail Corn. Aemetis Keyes, acting individually or as part of a strategic alliance, may source Corn directly from Corn growers or associations of Corn growers (“Direct Sourced Rail Corn”) from Union Pacific Railroad-approved 100-car shuttle loading facilities. If Aemetis Keyes procures Direct Sourced Rail Corn, Aemetis Keyes shall notify ▇▇▇▇▇▇▇▇ of the volume of Direct Sourced Rail Corn, which volume shall be reduced from the volume of Corn to be sourced by ▇▇▇▇▇▇▇▇ under this Agreement. [***].

(b) Direct Sourced Truck Corn. Aemetis Keyes, acting individually or as part of a strategic alliance, may source Corn directly from Corn growers or associations of Corn growers (“Direct Sourced Truck Corn”) from any local producer or seller of corn in California. If Aemetis Keyes procures Direct Sourced Truck Corn, [***].

(c) ▇▇▇▇▇▇▇▇ To Match Prices. If Aemetis Keyes is aware of Corn offered by a reliable supplier or at a FOB truck or rail point served by the UPRR and FOB price that equates to a lower delivered price to Aemetis Keyes for the same amount of Corn and the same shipment period as otherwise offered by ▇▇▇▇▇▇▇▇, then Aemetis Keyes will advise ▇▇▇▇▇▇▇▇ of such offers. [***]. Notwithstanding the foregoing and without regard to price, ▇▇▇▇▇▇▇▇ is not required to purchase any Corn that, when received by ▇▇▇▇▇▇▇▇, would overburden the receiving, storage or other logistical capacity of the ▇▇▇▇▇▇▇ Facility and/or the industry track serving its facility.

Section 1.04. Ownership and Sales. The parties agree that ▇▇▇▇▇▇▇▇ will own all inventory in Aemetis ▇▇▇▇▇’▇ Grain Bin and the Grain Day Tank (as each is defined in the Lease) and will deliver such inventory to Aemetis Keyes on a daily basis on the following conditions:

(a) ▇▇▇▇▇▇▇▇ will [***] to the purchase price of all Grain purchased by Aemetis Keyes on a daily basis for inventory shrinkage (at the point of origination) (“Shrink”). The amount of Shrink will be reflected on all invoices to Aemetis Keyes.

(b) Aemetis Keyes shall purchase and empty all inventory from the Grain Bin and the Grain Day Tank (each as defined in the Lease) at the Ethanol Plant at least once per quarter. ▇▇▇▇▇▇▇▇ and Aemetis Keyes will reconcile the inventory (“True Up”) when the inventory is removed from the tank quarterly. [***] agree to renegotiate the Shrink if it is consistently over or under.

(d) The in-line grain scale between the Ethanol Plant and Grain Day Tank will be used for the True Up and will govern the weights used for the True Up.

(e) The purchase price for the Grain to be delivered each day must be established before the time of delivery to the Ethanol Plant.

(f) Aemetis Keyes is ultimately responsible for all Shrink associated with the handling of Grain at the ▇▇▇▇▇▇▇ Feed Mill Storage and the Grain Day Tank.

Section 1.05. ▇▇▇▇▇▇▇▇ Sale Contracts. Oral agreements of sale will be recorded by ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇▇ will promptly thereafter generate and deliver to Aemetis Keyes a written agreement evidencing each individual sale of Grain to Aemetis Keyes (“Sale Contract”). The Sale Contract will govern the particulars of the sale [***] and shall constitute a binding obligation between ▇▇▇▇▇▇▇▇ and Aemetis Keyes. Aemetis Keyes will sign and return each Sale Contract or immediately notify ▇▇▇▇▇▇▇▇ of any discrepancy between the Sale Contract and the terms of the sale to which Aemetis Keyes orally agreed. If Aemetis Keyes fails to notify ▇▇▇▇▇▇▇▇ of such discrepancies [***], then such Sale Contract will be deemed final and binding notwithstanding Aemetis ▇▇▇▇▇’▇ failure or refusal to return the signed Sale Contract to ▇▇▇▇▇▇▇▇. Amendments to Sale Contracts will be confirmed in writing in the same manner as herein provided for the initial sale transaction. Any disputes related to a Sale Contract will be resolved by reference to National Grain and Feed Association (“NGFA”) Trade Rules as then in effect. Aemetis Keyes or ▇▇▇▇▇▇▇▇ may install telephone recording equipment to record all conversations as an additional measure to ensure accuracy. Sales Contracts shall be applied against usage on a FIFO basis for each specified delivery period, unless otherwise mutually agreed between Aemetis Keyes and ▇▇▇▇▇▇▇▇. A Sales Contract may be amended by mutual agreement of the parties. Further, if both parties mutually agree that a Sales Contract should be cancelled, then such Sales Contract shall be canceled at a mutually agreed price and the profit or loss resulting therefrom shall be applied to the next regular billing. Aemetis Keyes shall not unreasonably delay or withhold agreement to a commercially reasonable cancellation price as proposed by ▇▇▇▇▇▇▇▇.

Section 1.06. Settlement Weights. The in-line scale in the Ethanol Plant (located after the Grain Day Tank) will be used to determine the weights for the Grain purchased daily by Aemetis Keyes and, pursuant to Section 1.04(d), will be used in conjunction with the origin rail weights to establish the final governing weight for the True Up to calculate Shrink.

Section 1.07. Freight Adjustments. If fuel surcharges are added to freight rate by the UPRR (or, as to Milo, by the UPRR or the applicable shipping and/or trucking lines), then such charges shall be for the account of Aemetis Keyes and the price shall be adjusted upward to reflect the actual freight rate applicable to the shipment. ▇▇▇▇▇▇▇▇ shall notify Aemetis Keyes of any additional fuel surcharges [***] of receipt of such notice from the UPRR and/or trucking lines.

Section 1.08. NGFA Trade and Arbitration Rules. All Sale Contracts will be deemed to incorporate by reference the Trade Rules of the NGFA as then in effect, whether or not such incorporation is expressly stated in the Sale Contract itself. Disputes arising under Sale Contracts will be resolved by binding arbitration in accordance with the Arbitration Rules of the NGFA as then in effect, whether or not an arbitration agreement is expressly set forth in the disputed Sale Contracts. The Trade Rules and Arbitration Rules will govern as herein provided whether or not either or both of the parties are active members of the NGFA.

Section 1.09. Limitations of Sale Obligation. Subject to the rights of the Lenders under the Lender Consent, nothing contained in this Agreement will be construed to require ▇▇▇▇▇▇▇▇ to offer or sell Grain to Aemetis Keyes if (a) such offer or sale is for delivery dates more than [***] after the date of the offer or contract; (b) Aemetis Keyes is in material violation of this Agreement; (c) Aemetis Keyes is insolvent; (d) Aemetis Keyes is unable to receive Grain at the Ethanol Plant and has not specified an alternative delivery location; (e) Aemetis Keyes would exceed its Credit Limit (as defined below). For purposes of (b) above, “material violation of this Agreement” shall mean any monetary breach by Aemetis Keyes and any other breach which has a material adverse effect on (i) the rights and obligations of ▇▇▇▇▇▇▇▇ under this Agreement or any Related Agreement, or (ii) the ability of Aemetis Keyes to perform its obligations hereunder and under the Related Agreements, including without limitation if the Lenders cause any of the Aemetis Keyes credit facilities to be accelerated prior to such agreement’s stated maturity date or foreclose upon the Collateral (as defined in the Security Agreement). Furthermore Aemetis Keyes acknowledges and agrees that ▇▇▇▇▇▇▇▇ has no obligation to enter into Sale Contracts with Aemetis Keyes for the sale of Milo.

Section 1.10. Grain Quality. Nothing contained in this Agreement will be construed to require ▇▇▇▇▇▇▇▇ to purchase, for its own account or for immediate resale to Aemetis Keyes, Grain that is of inferior quality [***], except when such Grain can be received directly by Aemetis Keyes at the Ethanol Plant. Corn purchased by ▇▇▇▇▇▇▇▇ for Aemetis Keyes will be Number 2 as defined by the current industry standards for shuttle corn traded on the UPRR. Milo purchased by ▇▇▇▇▇▇▇▇ for Aemetis Keyes will be Grade #2 or better. All Grain supplied by ▇▇▇▇▇▇▇▇ pursuant to this Agreement shall be of a quality to permit the reasonable and efficient operation of the Ethanol Plant. Direct Sourced Rail Corn and Direct Sourced Truck Corn by Aemetis Keyes must meet the quality standard of US Number 2 yellow corn.

Section 1.11. Service Failures. The parties specifically acknowledge that the price of Corn sold by ▇▇▇▇▇▇▇▇ to Aemetis Keyes is based upon rail shipment by the UPRR under programs promulgated by the UPRR; however, it is not the intention of this Agreement to make either party a guarantor of the performance or service of the UPRR. Accordingly, if the UPRR for any reason fails in any material respect to provide rail service consistent with the expectations of the parties as represented by Sale Contracts, then both parties will make good-faith efforts to replace the supply of Corn or to re-price the Corn so that each is restored as nearly as possible to the position the parties would have been in but for the UPRR service failure. [***]

Section 1.12. Title to and Risk of Loss. Title to and risk of loss of Grain shall remain with ▇▇▇▇▇▇▇▇ until such Grain is purchased by Aemetis Keyes and delivered out of the ▇▇▇▇▇▇▇ Facility and the Grain Day Bin (as each such term is defined in the Lease) into the Ethanol Plant through the in-line scale. The in-line scale between the Ethanol Plant and the Grain Day Tank will be the official point of ownership transfer. Aemetis Keyes may specify an alternative delivery point or offsite storage locations to facilitate Ethanol Plant maintenance or mitigate anticipated Grain market disruptions, or for other commercially reasonable reasons which Aemetis Keyes will report to ▇▇▇▇▇▇▇▇. For deliveries to any location other than described above, Aemetis Keyes agrees to pay the additional handling costs incurred by ▇▇▇▇▇▇▇▇.

Section 1.13. Forward Contracts. ▇▇▇▇▇▇▇▇ is hereby authorized, upon receipt of written direction by Aemetis Keyes, to enter into forward contracts (“Forward Contracts”) regarding the Grain to be supplied hereunder. Aemetis Keyes shall be liable to ▇▇▇▇▇▇▇▇ for losses incurred in connection with such Forward Contracts as a result of early termination of this Agreement caused by Aemetis ▇▇▇▇▇’▇ default under this Agreement or the Related Agreements.

ARTICLE II

PURCHASE PRICE OF GRAIN AND HANDLING FEE

Section 2.01. Purchase Price of Grain. The purchase price of Grain shall include the agreed-to price for the Grain, including freight and transportation costs to the Ethanol Plant (“Purchase Price”).

Section 2.02. Service Fee. Aemetis Keyes agrees to pay a service fee for the procurement of Grain (“Service Fee”) by ▇▇▇▇▇▇▇▇, which fee shall include all services related to delivering Grain to the Ethanol Plant, including but not limited to sourcing, logistics, scheduling, accounting and transferring Grain from the ▇▇▇▇▇▇▇ Facility, then to the Grain Day Tank, and then to the Ethanol Plant. [***] plus any additional amount due ▇▇▇▇▇▇▇ above [***] Grain Handling Fee as defined in the Keyes Corn Handling Agreement. ▇▇▇▇▇▇▇▇ shall notify Aemetis Keyes of each such increase by delivery of a written statement setting forth the ▇▇▇▇▇▇▇ Handling Fee increase, if any, and the new Service Fee. ▇▇▇▇▇▇▇▇’▇ notice will be given on or before the effective date of the increase. In no event shall the Service Fee be reduced due to a change in the ▇▇▇▇▇▇▇ Handling Fee; provided, however, in the event that Milo delivered to the ▇▇▇▇▇ plant site is not subject to the [***] ▇▇▇▇▇▇▇ Handling Fee, the Service Fee payable to ▇▇▇▇▇▇▇▇ for any such shipment shall be reduced to reflect such savings; provided further, in no event shall [***] after payment of the ▇▇▇▇▇▇▇ Grain Handling Fee.

Section 2.03. UPRR Incentives. ▇▇▇▇▇▇▇ shall earn an unload incentive (the “Unload Incentive”) equal to any unload incentive paid by the UPRR to ▇▇▇▇▇▇▇▇ for the Corn transactions contemplated by this Agreement. This Unload Incentive will be credited weekly by ▇▇▇▇▇▇▇▇ to Aemetis Keyes as it is earned. Both ▇▇▇▇▇▇▇▇ and Aemetis Keyes agree and understand that ▇▇▇▇▇▇▇ is responsible for the majority of the actions that could result in the Unload Incentive being paid or not paid by the UPRR.

[***]

The trip incentive as paid by the UPRR (the “Trip Incentive”) for agreeing to operate a UPRR shuttle train will be negotiated independently as part of the cost of Corn. ▇▇▇▇▇▇▇▇ and Aemetis Keyes will negotiate in good faith a sharing with, or transfer to, Aemetis Keyes of the Trip Incentive concurrent with the pricing of the Corn. ▇▇▇▇▇▇▇▇ shall notify Aemetis Keyes of such incentives in a timely fashion.

Section 2.04. Separate Costs. Except as otherwise expressly provided in this Agreement, ▇▇▇▇▇▇▇▇ and Aemetis Keyes agree to be responsible for the cost of their own operations.

Section 2.05. The parties hereto have entered into an agreement with ▇▇▇▇▇▇▇ to unload and handle Grain for the parties. Subject to receipt of payment from Aemetis Keyes for the Service Fee and any express provisions to the contrary in this Agreement, [***] assumes the obligation to pay ▇▇▇▇▇▇▇ the handling fee for Grain specified pursuant to the ▇▇▇▇▇ Grain Handling Agreement.

ARTICLE III

RE-OPENING TERMS: PAYMENT AND CREDIT TERMS

Section 3.01. Re-Start Terms. In consideration of ▇▇▇▇▇▇▇▇’▇ entering into this Agreement and providing Grain in accordance with the amended and restated provisions of this Agreement, Aemetis Keyes agrees to the following Re-Start Terms:

(a) Aemetis Keyes shall pay to ▇▇▇▇▇▇▇▇ [***] (the “Re-Start Fee”) [***] after the Re-start (the “Re-Start Fee Accumulation Period”), such amount to be payable in daily equal installments (the “Daily Installments”) commencing thirty (30) days after the Re-start. The amounts due ▇▇▇▇▇▇▇▇ under this subsection shall be set-off by ▇▇▇▇▇▇▇▇ from amounts otherwise due to Aemetis Keyes in connection with ▇▇▇▇▇▇▇▇’▇ marketing of the Ethanol, WDGS, Corn Oil, and CDS/Syrup (together the “Ethanol Products”). For purposes of this Agreement: (i) “Ethanol” and “WDGS” shall have their respective meanings as set forth in the ▇▇▇▇▇▇▇▇ Purchasing Agreement; (ii) “CDS/Syrup” means concentrated distillers solubles, a low fiber, high protein product derived from the ethanol production process, also known as “Syrup”, and (iii) “Corn Oil” means corn oil, a high fat liquid product derived from the ethanol production process. In the event that set-off amounts are not sufficient to pay a Daily Installment, ▇▇▇▇▇▇▇▇ shall retain all payments due Aemetis Keyes in connection with ▇▇▇▇▇▇▇▇’▇ marketing of the Ethanol Products until such time as the Daily Installments then due to ▇▇▇▇▇▇▇▇ under this subsection (a) are current and paid in full. To the extent that any portion of the Re-Start Fee remains unpaid as of the expiration of the Re-Start Fee Accumulation Period (the “Final Maturity Date”), such outstanding balance shall bear interest at the rate of 18% per month until paid in full. Interest will be calculated based on actual days elapsed since the Final Maturity Date and a year of 365/366 days, as applicable.

(b) Aemetis Keyes shall pay to ▇▇▇▇▇▇▇▇ a [***] commencing January 16, 2013, until the day before the first Grain is ground as part of the Restart. Such amounts shall be payable in the manner and at the times set forth in Subsection 3.01 (a) above. Set-off amounts will be applied, first, as to the amounts due under this subsection (b) and, second, to the Re-Start Fee.

(c) Prior to the Effective Date, Aemetis Keyes has paid to ▇▇▇▇▇▇▇▇ the amount of [***]. This amount will be used, first, to pay for the Grain shrink payment, if any, due from Aemetis Keyes to ▇▇▇▇▇▇▇▇ at the Initial True-Up, and, second, as a payment toward amounts due under the Re-Start Fee. In the event that the shrink payment due to ▇▇▇▇▇▇▇▇ from Aemetis Keyes [***] shall be added to the then current balance of the Re-Start Fee and paid in accordance with Subsection 3.01 (a) above.

(d) On the Effective Date, Aemetis Keyes is delivering to ▇▇▇▇▇▇▇▇ [***]

Section 3.02. Payment Terms for Grain. Aemetis Keyes agrees that the Purchase Price and Service Fee will be due [***]. Notwithstanding this general rule, in consideration of Aemetis ▇▇▇▇▇’▇ entering into the Security Agreement and performing its obligations under this Agreement, ▇▇▇▇▇▇▇▇ agrees that so long as its security interest in the Collateral (as defined in the Security Agreement) remains a valid First Priority Security Interest, subject to the terms of this Section 3.02, ▇▇▇▇▇▇▇▇ shall permit payment of the Purchase Price and Service Fee to be payable and settled [***] following the applicable delivery. The credit limit [***] plus [***] minus,[***]. The Credit Limit shall cease immediately if (1) the liens in favor of ▇▇▇▇▇▇▇▇ under the Security Agreement shall at any time cease to constitute a First Priority Security Interest in the Collateral described therein, (2) the enforceability of the Security Agreement or the Lender Consent shall be repudiated in writing by Aemetis Keyes or the Lenders, or (3) any Event of Default (as defined below), or any event or condition which with the lapse of time, the giving of notice, or both, could constitute an Event of Default, shall occur hereunder, whereupon the Credit Limit shall, at ▇▇▇▇▇▇▇▇’▇ sole discretion and without notice, become [***]

Section 3.03. Credit Exposure Exceeding Credit Limit. Notwithstanding anything contained in this Agreement, ▇▇▇▇▇▇▇▇ may but is not required to [***] by entering into additional or new Sale Contracts that would result in [***]. The amount of any letter of credit which is reasonably acceptable to ▇▇▇▇▇▇▇▇, and which is provided to ▇▇▇▇▇▇▇▇ for credit support, will commensurately increase the Aemetis Keyes Credit Limit. The Credit Limit may be reviewed at any time and reduced by ▇▇▇▇▇▇▇▇ if reasonably required by ▇▇▇▇▇▇▇▇’▇ lenders or if failure to do so would cause a violation of ▇▇▇▇▇▇▇▇’▇ debt covenants, provided that ▇▇▇▇▇▇▇▇ shall promptly give Aemetis Keyes and the Lenders prior written notice of any required reduction of the Credit Limit (the “Reduction Notice”). Upon receipt of the Reduction Notice, Aemetis Keyes shall have the right to immediately terminate this Agreement upon written notice to ▇▇▇▇▇▇▇▇ and payment of all amounts due hereunder. If credit exposure exceeds the Credit Limit, such fact will not operate as or be deemed to be either an increase in the Credit Limit or a waiver of ▇▇▇▇▇▇▇▇’▇ rights hereunder.

Section 3.04. Financial Statements. Aemetis Keyes agrees to provide its annual audited financial statements to ▇▇▇▇▇▇▇▇ [***] after the same are completed and distributed to Aemetis ▇▇▇▇▇’▇ lenders. On a weekly basis, Aemetis Keyes will provide to ▇▇▇▇▇▇▇▇’▇ chief financial officer or his designee on the first business day of such week a statement from the Aemetis Keyes chief financial officer (or from a designee reasonably acceptable to ▇▇▇▇▇▇▇▇) certifying that Aemetis Keyes has paid and is current with the following vendors: Pacific Gas and Energy, Turlock Irrigation District, and Aemetis Keyes’ current natural gas supplier(s), or, in the case any such vendor is replaced by a different vendor or vendors, such successor vendor(s). Such statement may be supplied to ▇▇▇▇▇▇▇▇ by means of an email addressed to Heiskell at the email address or addresses supplied by Heiskell from time to time. In addition, Aemetis Keyes may provide such other or more frequent financial information as it may desire in support of application for an increase in the Credit Limit or different payment terms.

Title to the Grain shall pass to Aemetis Keyes at the point of the in-line scale. Aemetis Keyes shall maintain a properly certified scale to accurately weigh incoming Grain from the dedicated Grain tanks. The scale shall be tested and calibrated quarterly by Aemetis Keyes at Aemetis ▇▇▇▇▇’▇ cost [***]. If the scale is turned off or nonoperational for any reason, then the hourly Grain usage shall be calculated at the maximum [***] that was recorded during the previous [***] period unless both parties mutually agree to a different method of calculation.

▇▇▇▇▇▇▇▇ will obtain electronic readings of the Grain crossing the in-line scale on a daily basis (or as determined above if the scale is turned off or nonoperational for any reason) and will provide Aemetis Keyes each business day an invoice for delivered Grain on the previous day, including any unbilled period, such as weekends or holidays.

Section 5.02. Payment and Determination of Ethanol. The amount of Ethanol transferred from Aemetis Keyes to ▇▇▇▇▇▇▇▇ shall be based on the reading from the in-line meter [***] on the Ethanol Property (the “Ethanol Meter”). Title to the Ethanol shall pass to ▇▇▇▇▇▇▇▇ at the point of the in-line meter. Aemetis Keyes shall maintain a properly certified meter to accurately account for outgoing Ethanol from the Ethanol Plant. The meter shall be tested and calibrated quarterly by Aemetis Keyes at Aemetis ▇▇▇▇▇’▇ [***] is turned off or nonoperational for any reason, then the hourly Ethanol delivery shall be calculated [***] mutually [***]..

Section 5.03. Payment and Determination of WDGS and CDS/Syrup. The amount of WDGS and CDS/Syrup transferred and invoiced to ▇▇▇▇▇▇▇▇ shall be based on the reading from the Truck Scale installed on the Ethanol Property.

FORM OF STOCK WARRANT

THIS WARRANT AND THE COMMON SHARES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 OF SUCH ACT.”

Right to Purchase _________ shares of Common Stock

of AEMETIS, INC.

COMMON STOCK PURCHASE WARRANT

No. 2013

Issue Date: __________, 2013

AEMETIS, INC., a corporation organized under the laws of the State of Nevada (the “Company”), hereby certifies that, for value received, ▇.▇. ▇▇▇▇▇▇▇▇ Holdings, LLC, a California limited liability company, or its assigns (the “Holder”), is entitled, subject to the terms set forth below, to purchase from the Company at any time after the Issue Date until the Expiration Date, 1,000,000 fully paid and nonassessable shares of the Common Stock of the Company (the “Warrant Shares”), at a per share purchase price of $0.50 in lawful money of the United States. The afore described purchase price per share, as adjusted from time to time as herein provided, is referred to herein as the “Purchase Price.” The number and character of such shares of Common Stock and the Purchase Price are subject to adjustment as provided herein.

1. Definitions. As used herein the following terms, unless the context otherwise requires, have the following respective meanings:

(a) The term “Company” shall include AEMETIS, Inc. and any individual or entity which shall succeed or assume the obligations of AEMETIS, Inc. hereunder.

(b) The term “Common Stock” includes (i) the Company’s Common Stock, $.001 par value per share, as authorized on the Issue Date, and (ii) any other securities into which or for which any of the securities described in (i) may be converted or exchanged pursuant to a plan of recapitalization, reorganization, merger, sale of assets or otherwise.

(d) The term “Other Securities” refers to any stock (other than Common Stock) and other securities of the Company or any other person (corporate or otherwise) which the holder of the Warrant at any time shall be entitled to receive, or shall have received, on the exercise of the Warrant, in lieu of or in addition to Common Stock, or which at any time shall be issuable or shall have been issued in exchange for or in replacement of Common Stock or Other Securities pursuant to Section 3 or otherwise.

2. Exercise of Warrant.

(a) Number of Shares Issuable upon Exercise. From and after the Issue Date through and including the Expiration Date, the Holder hereof shall be entitled to receive, upon exercise of this Warrant in whole in accordance with the terms of subsection 2(b) or upon exercise of this Warrant in part in accordance with subsection 2(c), shares of Common Stock of the Company, subject to adjustment pursuant to Section 3.

(b) Full Exercise. This Warrant may be exercised in full by the Holder hereof by delivery of an original or facsimile copy of the form of subscription attached as Exhibit A hereto (the “Subscription Form”) duly executed by such Holder and surrender of the original Warrant within five (5) trading days of exercise, to the Company at its principal office, accompanied by payment, in cash, wire transfer or by certified or official bank check payable to the order of the Company, in the amount obtained by multiplying the number of shares of Common Stock for which this Warrant is then exercisable by the Purchase Price then in effect.

(c) Partial Exercise. This Warrant may be exercised in part (but not for a fractional share) by surrender of this Warrant in the manner and at the place provided in subsection 2(b) except that the amount payable by the Holder on such partial exercise shall be the amount obtained by multiplying (a) the number of whole shares of Common Stock designated by the Holder in the Subscription Form by (b) the Purchase Price then in effect. On any such partial exercise, the Company, at its expense, will forthwith issue and deliver to or upon the order of the Holder hereof a new Warrant of like tenor, in the name of the Holder hereof or as such Holder (upon payment by such Holder of any applicable transfer taxes) may request, the whole number of shares of Common Stock for which such Warrant may still be exercised.

(d) Fair Market Value. Fair Market Value of a share of Common Stock as of a particular date (the “Determination Date”) shall mean:

(i) If the Company’s Common Stock is traded on an exchange, then the closing or last sale price, respectively, reported for the last business day immediately preceding the Determination Date;

(ii) If the Company’s Common Stock is not traded on an exchange, but is traded in the over-the-counter market, then the average of the closing bid and ask prices reported for the last business day immediately preceding the Determination Date;

(iii) Except as provided in clause (iv) below, if the Company’s Common Stock is not publicly traded, then as the Board of Directors of the Company shall in good faith determine; or

(iv) If the Determination Date is the date of a liquidation, dissolution or winding up, or any event deemed to be a liquidation, dissolution or winding up pursuant to the Company’s charter, then all amounts to be payable per share to holders of the Common Stock pursuant to the charter in the event of such liquidation, dissolution or winding up, plus all other amounts to be payable per share in respect of the Common Stock in liquidation under the charter, assuming for the purposes of this clause (iv) that all of the shares of Common Stock then issuable upon exercise of all of the Warrants are outstanding at the Determination Date.

(e) Delivery of Stock Certificates, etc. on Exercise. As soon as practicable after the exercise of this Warrant in full or in part, and in any event within five (5) trading days thereafter, the Company at its expense will cause to be issued in the name of and delivered to the Holder hereof, or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct in compliance with applicable securities laws, a certificate or certificates for the number of duly and validly issued, fully paid and nonassessable shares of Common Stock (or Other Securities) to which such Holder shall be entitled on such exercise, plus, in lieu of any fractional share to which such Holder would otherwise be entitled, cash equal to such fraction multiplied by the then Fair Market Value of one full share of Common Stock, together with any other stock or other securities and property (including cash, where applicable) to which such Holder is entitled upon such exercise pursuant to Section 2 or otherwise.

(f) Common Stock Legend. The Holder acknowledges and agrees that the shares of Common Stock of the Company, and, until such time as the Common Stock has been registered under the 1933 Act and sold in accordance with an effective registration statement, or exemption from registration, certificates and other instruments representing any of the Common Stock shall bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of any such Securities):

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED OR APPLICABLE STATE SECURITIES LAWS. THESE SHARES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAW OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO AEMETIS, INC. THAT SUCH REGISTRATION IS NOT REQUIRED.”

(g) Cashless Exercise. If the Fair Market Value of one share of Common Stock is greater than the Purchase Price (at the date of calculation as set forth below), in lieu of exercising this Warrant for cash, the holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being cancelled) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Subscription Form in which event the Company shall issue to the holder a number of shares of Common Stock computed using the following formula:

X = Y (A-B)

Where

the number of shares of Common Stock to be issued to the holder

the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being exercised (at the date of such calculation)

the Fair Market Value of one share of the Company’s Common Stock (at the date of such calculation)

Purchase Price (as adjusted to the date of such calculation)

3. Adjustment for Reorganization.

(a) Reorganization, Consolidation, Merger, etc. In case at any time or from time to time, the Company shall effect a reorganization, then, as a condition to the consummation of such a transaction, proper and adequate provision shall be made by the Company whereby the Holder of this Warrant, on the exercise hereof as provided in Section 1, at any time after the consummation of such reorganization shall receive, in lieu of the Common Stock (or Other Securities) issuable on such exercise prior to such consummation or such effective date, the stock and other securities and property to which such Holder would have been entitled upon such consummation if such Holder had so exercised this Warrant, immediately prior thereto, all subject to further adjustment thereafter as provided in this Section 3.

(b) Extraordinary Events Regarding Common Stock. In the event that the Company shall (a) issue additional shares of the Common Stock as a dividend or other distribution on outstanding Common Stock, (b) subdivide its outstanding shares of Common Stock, or (c) combine its outstanding shares of the Common Stock into a smaller number of shares of the Common Stock, then, in each such event, the Purchase Price shall, simultaneously with the happening of such event, be adjusted by multiplying the then Purchase Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Purchase Price then in effect. The Purchase Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described herein in this Section 3. The number of shares of Common Stock that the Holder of this Warrant shall thereafter, on the exercise hereof as provided in Section 2, be entitled to receive shall be adjusted to a number determined by multiplying the number of shares of Common Stock that would otherwise (but for the provisions of this Section 3) be issuable on such exercise by a fraction of which (a) the numerator is the Purchase Price that would otherwise (but for the provisions of this Section 3) be in effect, and (b) the denominator is the Purchase Price in effect on the date of such exercise.

(c) Certificate as to Adjustments. In each case of any adjustment or readjustment in the shares of Common Stock (or Other Securities) issuable on the exercise of the Warrants, the Company at its expense will promptly cause its Chief Financial Officer or other appropriate designee to compute such adjustment or readjustment in accordance with the terms of the Warrant and prepare a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based, including a statement of (a) the consideration received or receivable by the Company for any additional shares of Common Stock (or Other Securities) issued or sold or deemed to have been issued or sold, (b) the number of shares of Common Stock (or Other Securities) outstanding or deemed to be outstanding, and (c) the Purchase Price and the number of shares of Common Stock to be received upon exercise of this Warrant, in effect immediately prior to such adjustment or readjustment and as adjusted or readjusted as provided in this Warrant. The Company will forthwith mail a copy of each such certificate to the Holder of the Warrant.

4. Reservation of Stock, etc. Issuable on Exercise of Warrant; Financial Statements. The Company will at all times reserve and keep available, solely for issuance and delivery on the exercise of the Warrants, all shares of Common Stock (or Other Securities) from time to time issuable on the exercise of the Warrant.

5. Assignment; Exchange of Warrant. Subject to compliance with applicable securities laws, this Warrant, and the rights evidenced hereby, may be transferred by any registered holder hereof (a “Transferor”). On the surrender for exchange of this Warrant, with the Transferor’s endorsement in the form of Exhibit B attached hereto (the “Transferor Endorsement Form”) and together with an opinion of counsel reasonably satisfactory to the Company that the transfer of this Warrant will be in compliance with applicable securities laws, the Company at its expense, twice, only, but with payment by the Transferor of any applicable transfer taxes, will issue and deliver to or on the order of the Transferor thereof a new Warrant or Warrants of like tenor, in the name of the Transferor and/or the transferee(s) specified in such Transferor Endorsement Form (each a “Transferee”), calling in the aggregate on the face or faces thereof for the number of shares of Common Stock called for on the face or faces of the Warrant so surrendered by the Transferor. No such transfers shall result in a public distribution of the Warrant.

6. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement or security reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and cancellation of this Warrant, the Company at its expense, twice only, will execute and deliver, in lieu thereof, a new Warrant of like tenor.

7. Transfer on the Company’s Books. Until this Warrant is transferred on the books of the Company, the Company may treat the registered holder hereof as the absolute owner hereof for all purposes, notwithstanding any notice to the contrary.

8. Notices. All notices, demands, requests, consents, approvals, and other communications required or permitted hereunder shall be in writing and, unless otherwise specified herein, shall be (i) personally served, (ii) deposited in the mail, registered or certified, return receipt requested, postage prepaid, (iii) delivered by reputable air courier service with charges prepaid, or (iv) transmitted by hand delivery, telegram, or facsimile, addressed as set forth below or to such other address as such party shall have specified most recently by written notice.
