SECTION 3.1 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Cilion Capital Stock or any shares of capital stock of Merger Sub:

(a) Capital Stock of Merger Sub. Each issued and outstanding share of capital stock of Merger Sub shall be automatically converted into and become one fully paid and nonassessable share of common stock, par value $.01 per share, of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Aemetis-Owned Stock. Each share of Cilion Capital Stock, that is directly owned by Cilion, Merger Sub or Aemetis shall automatically be canceled and shall cease to be outstanding, and no consideration shall be delivered in exchange therefor.

(i) Series C Preferred Stock. Each share of Series C Preferred Stock issued and outstanding immediately prior to the Effective Time (excluding Dissenting Shares) shall be automatically converted into, subject to and in accordance with Section 3.5, the right to receive an amount equal to the Closing Date Preferred Per Share Consideration

(ii) Series B Preferred Stock and Series A Preferred Stock. Each share of Series B Preferred Stock and Series A Preferred Stock issued and outstanding immediately prior to the Effective Time (excluding Dissenting Shares) shall be automatically converted into, subject to and in accordance with Section 3.5, the right to receive (A) the Closing Date Preferred Per Share Consideration and (B) the Contingent Per Share Consideration. Notwithstanding the foregoing, if any holder of Series B Preferred Stock or Series A Preferred Stock shall not qualify as an Accredited Investor as of the Closing Date, then, in lieu of Stock Merger Consideration to which such holder would otherwise have been entitled had such holder been an Accredited Investor, such holder shall receive Cash Merger Consideration in an amount equal to the applicable portion of the Stock Merger Consideration valued at the Fair Market Value, and the aggregate Cash Merger Consideration and Stock Merger Consideration payable to the other holders of Cilion Preferred Stock shall be correspondingly adjusted.

(d) Cilion Common Stock. Each share of Cilion Common Stock issued and outstanding immediately prior to the Effective Time shall automatically be canceled and shall cease to be outstanding, and no consideration shall be delivered in exchange therefor.

(e) Cilion Stock Options. In connection with the Merger, each Cilion Option outstanding immediately prior to the Effective Time shall be cancelled, without any action on the part of the holder of such Cilion Option, as of the Effective Time and no consideration shall be paid to any holder of a Cilion Option as a result of such cancellation. Cilion shall take such actions as are necessary and appropriate to cause each Cilion Option to be cancelled as of the Effective Time for no consideration.

(f) Cilion Warrants. At the Effective Time, all Cilion Warrants shall have been cancelled and shall have ceased to exist, and no consideration shall have been paid to any holder of a Cilion Warrant as a result of such cancellation. Cilion shall take such actions as are necessary and appropriate to cause each Cilion Warrant to be cancelled as of the Effective Time for no consideration.

SECTION 3.2 Dissenters’ Rights. Notwithstanding any provision of this Agreement to the contrary, any shares of Cilion Capital Stock held by a Securityholder who has not voted in favor of the Merger or consented thereto in writing, and who has properly exercised and perfected such Securityholder’s right for appraisal of such shares in accordance with Section 262 of the DGCL and who, as of the Effective Time, has not effectively withdrawn or lost such right to appraisal (“Dissenting Shares”), if any, shall not be converted into the right to receive the respective portion of the Merger Consideration but shall instead be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Shares pursuant to the DGCL. Cilion shall give Aemetis prompt notice of any demand received by Cilion for appraisal of any shares of Cilion Capital Stock, and Aemetis shall have the right to direct and participate in all negotiations and proceedings with respect to such demand. Cilion agrees that, except with the prior written consent of Aemetis, or as required under the DGCL, it will not voluntarily make any payment with respect to, or settle or offer to settle, any such demand. Each holder of Dissenting Shares (“Dissenting Securityholder”) who, pursuant to the provisions of the DGCL, becomes entitled to payment of the fair value for shares of Cilion Capital Stock shall receive payment therefore (but only after the value therefore shall have been agreed upon or finally determined pursuant to such provisions). If, after the Effective Time, any Dissenting Securityholder shall effectively withdraw or lose (through failure to perfect or otherwise) such Dissenting Securityholder’s appraisal rights under Section 262 of the DGCL then, as of the later of the Effective Time and the occurrence of such event, such Dissenting Securityholder’s shares shall automatically be converted into and represent only the right to receive the Merger Consideration for such shares set forth in Section 3.1(c), as applicable, without interest, upon surrender of the certificate representing such shares. Any amounts that become payable in respect of Dissenting Shares shall be satisfied first from the Exchange Fund up to the applicable Merger Consideration that would have been otherwise payable in respect of such Dissenting Share at the Closing if such Dissenting Share were not a Dissenting Share, and thereafter from Aemetis.

SECTION 3.3 Closing Payment Schedule. At the Closing, Cilion shall deliver to Aemetis a definitive closing payment schedule (the “Closing Payment Schedule”) certified by the President of Cilion (solely in his capacity as such) and accurately setting forth: (i) the name of each Securityholder of Cilion immediately prior to the Effective Time; (ii) the number of shares of Cilion Capital Stock held by each such Securityholder immediately prior to the Effective Time; (iii) the aggregate Merger Consideration which each Securityholder is eligible to receive, including the allocation of Cash Merger Consideration, Stock Merger Consideration and Contingent Merger Consideration for each such holder; (iv) each Securityholder’s status as an Accredited Investor based upon completion of an Accredited Investor Questionnaire (to the extent completed by such Securityholder and submitted to Cilion); (v) the Closing Date Cash Balance; and (vi) the Closing Date Indebtedness. The Closing Payment Schedule shall be subject to update by the Securityholders’ Representative from time to time after the Closing to reflect any Dissenting Shares and any corresponding changes (neither such updates nor the information updated shall be deemed inaccuracies in the Closing Payment Schedule).

SECTION 3.4 Assignment of Proceeds.

(a) Payment Upon Milestone Financing(s). Within three (3) Business Days following the satisfaction of the Milestone Financing(s), Aemetis shall pay in cash an amount equal to the Contingent Merger Consideration to the holders of Series A Preferred Stock and Series B Preferred Stock in accordance with the Closing Payment Schedule. Aemetis covenants and agrees that it shall, and it shall cause its Affiliates to, not take any action, or fail to take any action, with the intent of circumventing the purpose of Section 3.4(a). Notwithstanding the foregoing, in the event Aemetis or any of its Subsidiaries issues or sells Equity Securities that results in at least $50,000,000 in gross cash proceeds, in the aggregate (whether in one transaction or multiple transactions), but the average issue price is less than $2.00 per share (subject to adjustment for any stock split, stock dividend, recapitalization, subdivision, reclassification, combination, exchange of shares or similar transaction with respect to the outstanding Aemetis Common Stock), then on the fifteenth Business Day of the first calendar month immediately following the date Aemetis or any of its Subsidiaries raises at least fifty million dollars ($50,000,000) in gross cash proceeds and on the fifteenth Business Day of each calendar month thereafter until the Contingent Merger Consideration is paid in full, Aemetis shall pay in cash an amount an amount equal to 0.25 times the Free Cash Flow of the prior calendar month to the holders of Series A Preferred Stock and Series B Preferred Stock in accordance with the Closing Payment Schedule; provided the foregoing shall not limit in any way the obligation to pay in full the Contingent Merger Consideration once the Milestone Financing has been achieved.

(b) Payment Upon Milestone Debt Payoff. On the fifteenth Business Day of the first calendar month immediately following the satisfaction of the Debt Milestone and on the fifteenth Business Day of each calendar month thereafter until the Contingent Merger Consideration is paid in full, Aemetis shall pay in cash an amount equal to 0.25 times the Free Cash Flow of the prior calendar month to the holders of Series A Preferred Stock and Series B Preferred Stock in accordance with the Closing Payment Schedule; provided the foregoing shall not limit in any way the obligation to pay in full the Contingent Merger Consideration once the Milestone Financing has been achieved. Aemetis covenants and agrees that it shall, and it shall cause its Affiliates to, not take any action, or fail to take any action, with the intent of circumventing the purpose of Section 3.4(b).

(c) Change of Control Upon the occurrence of a Change of Control, and after payment or assumption by the acquiror of all Indebtedness of Aemetis, but prior to the payment to any holders of Equity Securities of Aemetis, (i) Aemetis shall pay in cash an amount equal to the Contingent Merger Consideration to the holders of Series A Preferred Stock and Series B Preferred Stock in accordance with the Closing Payment Schedule.

(d) Audit. Upon the written request of the Securityholders’ Representative, Aemetis shall permit the Securityholders’ Representative and its Representatives to have access during normal business hours to the financial records of Aemetis as may be reasonably necessary to verify the compliance with this Section 3.4. The Securityholders’ Representative may at any time deliver to Aemetis a written statement describing its objections to determination with respect to the satisfaction of any milestone set forth above. If the Securityholders’ Representative raises any such questions or objections that cannot be resolved through the good faith negotiation of Aemetis and the Securityholders’ Representative within thirty (30) calendar days after the delivery of notice of such objections to Aemetis, then each party may pursue any legal remedies available to such party hereunder subject to the terms and conditions of this Agreement.

(e) Unclaimed Payments. Neither Aemetis nor the Exchange Agent shall be liable to any person in respect of the Contingent Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any portion of the Contingent Merger Consideration made by Aemetis remains unclaimed by a holder as of the date that is one year after the Milestone Payment Date (or immediately prior to such earlier date on which the Contingent Merger Consideration would otherwise escheat to or become the property of any Governmental Entity), despite the Exchange Agent’s commercially reasonable efforts to deliver the payment to a holder, any such Contingent Merger Consideration shall be delivered to Aemetis upon demand, and any such holder shall thereafter look only to Aemetis for satisfaction of such holder’s claims for the Contingent Merger Consideration.

(f) No Voting, Dividends or Interest; No Equity or Ownership Interest in Aemetis. A holder’s right to the Assignment of Proceeds Amount shall not give such holder any voting or dividend rights, or represent any equity or ownership interest in Aemetis, Merger Sub or Cilion.

SECTION 3.5 Exchange of Certificates.

(a) Exchange Agent. Prior to the Effective Time, Aemetis and Securityholders’ Representative shall enter into an exchange agent agreement with CSC Trust Co. (the “Exchange Agent”) in the form attached hereto as Exhibit C (the “Exchange Agreement”), which shall provide that Aemetis shall deposit with the Exchange Agent as of the Effective Time, for the benefit of the Securityholders, for exchange in accordance with this Article III, through the Exchange Agent, certificates and cash representing the Cash Merger Consideration and Stock Merger Consideration issuable pursuant to Section 3.1 in exchange for outstanding shares of Cilion Preferred Stock. All shares of Aemetis Common Stock and cash deposited with the Exchange Agent pursuant to this Section 3.4(a) shall hereinafter be referred to as the “Exchange Fund”. In accordance with the terms of the Exchange Agreement, the Exchange Agent shall deliver Cash Merger Consideration and Stock Merger Consideration contemplated to be issued pursuant to this Section 3.4(a) out of the Exchange Fund. Except as otherwise contemplated herein, the Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. Promptly following the Effective Time, but in any event not more than seven (7) Business Days after the Closing Date, Aemetis or Exchange Agent, as applicable, shall mail or otherwise deliver to each holder of record of Cilion Capital Stock, whose shares were converted into the right to receive the Merger Consideration pursuant to Section 3.1, (a) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates (defined below) shall pass, only upon receipt of the Certificates by the Exchange Agent) in the form attached hereto as Exhibit D, and which letter of transmittal shall also require each holder of record of Cilion Capital Stock, as a condition to its right to receive the Merger Consideration pursuant to Section 3.1, to execute and deliver with such letter of transmittal (1) a release of Cilion and its Subsidiaries, Affiliates and Representatives, (2) and an acknowledgement of the accuracy of the Merger Consideration to be received by such holder (the “Letter of Transmittal”); (b) such other customary documents as may be required by the Exchange Agent pursuant to such instructions; and (c) instructions for use in effecting the surrender of the certificate or certificates that represent outstanding shares of Cilion Capital Stock (the “Certificates”, and together with items (a), (b) and (c), the “Securityholder Documents”) in exchange for the such holder’s respective portion of the Merger Consideration as described in Section 3.1(a). Upon surrender of a Certificate for cancellation to the Exchange Agent, together with the Securityholder Documents, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefore the applicable Merger Consideration as described in Section 3.1. The Certificate so surrendered shall forthwith be canceled. Until so surrendered, each outstanding Certificate that prior to the Effective Time represented shares of Cilion Capital Stock will be deemed from and after the Effective Time, for all corporate purposes other than the payment of dividends, to evidence the right to receive the portion of the Merger Consideration which shall be issued for such Cilion Capital Stock.

(c) Distributions with Respect to Unsurrendered Certificates. Whenever a dividend or other distribution is declared or made after the date hereof with respect to Aemetis Common Stock with a record date after the Effective Time, such declaration shall include a dividend or other distribution in respect of all shares of Aemetis Common Stock issuable pursuant to this Agreement. Any dividends or other distributions with respect to Aemetis Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Aemetis Common Stock represented thereby, and any cash payment in lieu of fractional shares of Aemetis Common Stock shall be paid to any such holder pursuant to Section 3.6 only upon the surrender of such Certificate by the holder of record of such Certificate in accordance with this Article III. Subject to the effect of applicable escheat or similar laws, following surrender of any such Certificate there shall be paid to the holder of the certificate representing whole shares of Aemetis Common Stock, issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Aemetis Common Stock and the amount of any cash payable in lieu of a fractional share of Aemetis Common Stock to which such holder is entitled pursuant to Section 3.6 and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of Aemetis Common Stock.

SECTION 3.6 No Further Ownership Rights in Cilion Capital Stock. All Closing Shares and Cash Merger Consideration issued upon the surrender for exchange of Certificates in accordance with the terms of this Article III shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Cilion Capital Stock previously represented by such Certificates, subject, however, to the Surviving Corporation’s obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been declared or made by Cilion on such shares of Cilion Capital Stock, which remain unpaid at the Effective Time, and there shall be no further registration of transfers on the share transfer books of the Surviving Corporation of the shares of Cilion Capital Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article III.

SECTION 3.7 No Fractional Shares.

(a) No certificates or scrip representing fractional shares of Aemetis Common Stock shall be issued upon the surrender for exchange of Certificates (or in the case of a lost, stolen or destroyed Certificate, upon delivery of an affidavit in the manner provided in Section 3.1(i)), no dividends or other distributions of Aemetis shall relate to such fractional share interests and such fractional share interests will not entitle the owner thereof to vote or to any rights of a shareholder of Aemetis.

(b) In lieu of such fractional share interests, Aemetis shall pay to each holder of a Certificate an amount in cash equal to the product obtained by multiplying (A) the fractional share interest to which such holder (after taking into account all shares of Cilion Capital Stock formerly represented by all Certificates surrendered by such holder) would otherwise be entitled by (B) the Fair Market Value of one share of Aemetis Common Stock.

SECTION 3.8 Anti-Dilution Provisions. In the event Aemetis changes (or establishes a record date for changing) the number of shares of Aemetis Common Stock issued and outstanding prior to the Effective Time as a result of a stock split, stock dividend, recapitalization, subdivision, reclassification, combination, exchange of shares or similar transaction with respect to the outstanding Aemetis Common Stock and the record date therefor shall be prior to the Effective Time, the Stock Merger Consideration and the Termination Fee shall be proportionately adjusted to reflect such stock split, stock dividend, recapitalization, subdivision, reclassification, combination, exchange of shares or similar transaction.

SECTION 3.9 Unclaimed Exchange Fund. Any portion of the Cash Merger Consideration and Stock Merger Consideration that remains undistributed to the holders of the Certificates for twelve months after the Effective Time shall be delivered to Aemetis, upon demand, and any holders of the Certificates who have not theretofore complied with this Article III shall thereafter look only to Aemetis for, and Aemetis shall remain liable for, payment of their claim for the applicable Merger Consideration, any dividends or other distributions payable pursuant to Section 3.1 and cash in lieu of any fractional shares payable pursuant to Section 3.7 in accordance with this Article III.

SECTION 3.10 No Liability. None of Aemetis, Sub, Merger Sub, Cilion, the Surviving Corporation or the Exchange Agent shall be liable to any person in respect of any shares of Aemetis Common Stock, cash, dividends or other distributions from the Exchange Fund properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to four years after the Effective Time (or immediately prior to such earlier date on which any Cash Merger Consideration and Stock Merger Consideration (and any dividends or other distributions payable with respect thereto pursuant to Section 3.5(c) and Section 3.8 and cash in lieu of any fractional shares payable with respect thereto pursuant to Section 3.7) would otherwise escheat to or become the property of any Governmental Entity), any such Cash Merger Consideration and Stock Merger Consideration (and any dividends or other distributions payable with respect thereto pursuant to Section 3.5(c) and cash in lieu of any fractional shares payable with respect thereto pursuant to Section 3.7) shall, to the extent permitted by applicable law, become the property of Aemetis, free and clear of all claims or interest of any person previously entitled thereto.

SECTION 3.11 Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, the Exchange Agent shall deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration, any dividends or other distributions payable pursuant to Section 3.4(c) and cash in lieu of any fractional shares payable pursuant to Section 3.6, in each case pursuant to this Article III.

SECTION 3.12 Withholding Rights. Aemetis, the Surviving Corporation or the Exchange Agent shall be entitled, but only with the prior consultation of the Securityholders’ Representative, to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Certificates such amounts as Aemetis, the Surviving Corporation or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Aemetis, the Surviving Corporation or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Certificates in respect of which such deduction and withholding was made by Aemetis, the Surviving Corporation or the Exchange Agent.

SECTION 3.13 Aemetis Common Stock Legend. The holders of Cilion Capital Stock receiving Aemetis Common Stock as set forth on the Closing Payment Schedule shall individually be referred to as an “Aemetis Common Stock Recipient” or collectively as the “Aemetis Common Stock Recipients.” Until the resale by the Aemetis Common Stock Recipients of their Aemetis Common Stock has become registered under the Securities Act, or otherwise transferable pursuant to an exemption from such registration otherwise required thereunder, the Aemetis Common Stock issued to the Aemetis Common Stock Recipients hereunder shall be characterized as “restricted securities” under the Securities Act and, if certificated, shall bear the following legend:

“THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES ONLY, AND THE RESALE OF SUCH SHARES HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH SHARES MAY NOT BE RESOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION WITHOUT AN EXEMPTION UNDER THE SECURITIES ACT.”

(iii) The execution and delivery of this Agreement by Cilion does not, and the consummation of the transactions contemplated hereby will not, conflict with, or result in any violation of, or default under (with or without notice or lapse of time, or both), or give rise to a right of termination, cancellation or acceleration of any obligation or loss of any benefit under (A) any provision of the Cilion Certificate of Incorporation or Bylaws of Cilion, as amended, or the charter documents of any Cilion Subsidiary, as amended; or (B) except as set forth in Section 4.1(c) of the Cilion Disclosure Schedule, any Material Contract, (C) the Cilion Permits (as hereinafter defined), or (D) any statute, law, ordinance, rule or regulation applicable to Cilion or its business or any Cilion Subsidiary, in the cases of subsections (B), (C) and (D), that would have or would be reasonably expected to have a Material Adverse Effect on Cilion.

(e) Financial Statements.

(i) Except as set forth on Section 4.1(e) of the Cilion Disclosure Schedule, Cilion has delivered to Aemetis the audited financial statements of Cilion for the fiscal years ended December 31, 2008, 2009, 2010 and 2011, and the unaudited financial statements (consolidated balance sheet, consolidated statement of operations and consolidated statement of cash flows) of Cilion on a consolidated basis as at and for the fiscal period ended March 31, 2012 (collectively, the “Cilion Financial Statements”). The Cilion Financial Statements have been prepared in accordance with GAAP (except that the unaudited financial statements do not contain footnotes and are subject to normal recurring year-end audit adjustments, the effect of which is not expected in the aggregate to have a Material Adverse Effect with respect to Cilion) applied on a consistent basis throughout the periods presented.

(f) To the Knowledge of Cilion, there are no circumstances that would require Cilion to restate any of the Cilion Financial Statements. Cilion has not had any material dispute with any of its auditors regarding accounting matters or policies during any of its past three (3) full fiscal years or during the current fiscal year to the date hereof. Neither Cilion nor any Cilion Subsidiary has any material obligations or liabilities of a type required to be reflected on a balance sheet prepared in accordance with GAAP, other than those obligations, liabilities or commitments (i) adequately provided for in the Cilion Balance Sheet, and (ii) incurred in the ordinary course of business since the Cilion Balance Sheet Date.

(g) Litigation.

(ii) There is no judgment, decree or order against Cilion or any Cilion Subsidiary or, to Cilion’s Knowledge, any of their respective directors or officers (in their capacities as such), that (A) restricts in any manner the use, transfer or licensing of any Cilion Proprietary Rights; (B) would prevent, enjoin, or materially alter or delay any of the transactions contemplated by this Agreement; or (C) that would reasonably be expected to have a Material Adverse Effect on Cilion.

(h) Restrictions on Business Activities. Except as set forth in Section 4.1(h) of the Cilion Disclosure Schedule, there is no agreement, judgment, injunction, order or decree binding upon Cilion or any Cilion Subsidiary that has or would reasonably be expected to have the effect of prohibiting or materially impairing any current business practice of Cilion or any Cilion Subsidiary, any acquisition of property by Cilion or any Cilion Subsidiary or the conduct of business by Cilion or any Cilion Subsidiary as currently conducted by Cilion or any Cilion Subsidiary, as the case may be.

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

SECTION 9.2 Waiver. No failure on the part of any party to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No party shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

SECTION 9.5 Cooperation. Cilion and Aemetis agree to cooperate fully with Aemetis and Cilion, respectively, and to execute and deliver such further documents, certificates, agreements and instruments and to take such other actions as may be reasonably requested by Aemetis or Cilion to evidence or reflect the transactions and to carry out the intent and purposes of this Agreement.

SECTION 9.6 Interpretation. The parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement. When a reference is made in this Agreement to an Article, Section or Exhibit, such reference shall be to an Article or Section of, or an Exhibit to, this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”. The words “hereby”, “hereof”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The words “date hereof” shall refer to the date of this Agreement. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”. The term “or” shall not be deemed to be exclusive. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein. References to a person are also to its permitted successors and assigns.

SECTION 9.7 Entire Agreement; Counterparts; Exchanges by Facsimile. This Agreement and the other agreements referred to herein constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof and thereof; provided, however, that the Confidentiality Agreement shall not be superseded and shall remain in full force and effect in accordance with its terms (it being understood that no provision in the Confidentiality Agreement shall limit any party’s rights or remedies in the case of fraud). This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by facsimile or electronic transmission shall be sufficient to bind the parties to the terms and conditions of this Agreement.

SECTION 9.8 Assignability; No Third Party Rights. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties hereto and their respective successors and assigns; provided, however, that neither this Agreement nor any party’s rights or obligations hereunder may be assigned or delegated by such party without the prior written consent of the other parties, and any attempted assignment or delegation of this Agreement or any of such rights or obligations by any party without the prior written consent of the other parties shall be void and of no effect; provided, further, that notwithstanding anything to the contrary in the foregoing, each of Aemetis, Sub and Merger Sub may assign its rights and interests hereunder to the Lenders for collateral security purposes pursuant to the terms of the Commitment Letter; provided that any such assignment by Aemetis or Merger Sub shall not relieve the assigning party of its obligations hereunder. Except for the right of holders of Cilion Capital Stock to receive the Merger Consideration in accordance with Section 3.1, nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the parties hereto) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

SECTION 9.9 Governing Law; Venue. This Agreement shall be governed by, and construed in accordance with, the laws of the State of California, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. In any action between any of the parties arising out of or relating to this Agreement or any of the transactions contemplated hereby: (a) each of the parties irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Superior Court of the State of California; and (b) each of the parties irrevocably waives the right to trial by jury. Each of the parties hereto further agrees that, to the fullest extent permitted by applicable law, service of any process, summons, notice or document by U.S. registered mail to such Person’s respective address set forth in Section 8.2 will be effective service of process for any claim, action, suit or other proceeding in the Superior Court of the State of California with respect to any matters to which it has submitted to jurisdiction as set forth in this paragraph. The parties hereto hereby agree that a final judgment in any such claim, suit, action or other proceeding will be conclusive, subject to any appeal, and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement without the requirement for the posting of any bond, this being in addition to any other remedy to which they are entitled at law or in equity. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

SECTION 9.10 Disclosure Schedules. The Cilion Disclosure Schedule shall be arranged in separate parts corresponding to the numbered and lettered sections contained in Section 4.1. The Aemetis Disclosure Schedule shall be arranged in separate parts corresponding to the numbered and lettered sections contained in Section 4.2. For purposes of this Agreement: (a) each statement or other item of information set forth in the Cilion Disclosure Schedule shall qualify other sections and subsections in Section 4.1 to the extent it is readily apparent from a reading of the disclosure that such disclosure is applicable to such other sections and subsections; and (b) each statement or other item of information set forth in the Aemetis Disclosure Schedule is intended shall qualify other sections and subsections in Section 4.2 to the extent it is readily apparent from a reading of the disclosure that such disclosure is applicable to such other sections and subsections. The Cilion Disclosure Schedule and Aemetis Disclosure Schedule shall each be delivered as of the date hereof, and no amendments or modifications thereto shall be made. Any purported update or modification to the Cilion Disclosure Schedule or Aemetis Disclosure Schedule after the date hereof shall be disregarded.

SECTION 9.11 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

SECTION 9.12 Personal Liability. Except as expressly set forth herein, this Agreement shall not create or be deemed to create or permit any personal liability or obligation on the part of any direct or indirect stockholder of Cilion or any officer, director, employee, representative, agent or investor of any party hereto.

SECTION 9.13 Absence of Presumption. The parties hereto have participated jointly in the negotiation and drafting of this Agreement and, in the event of ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by such parties and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement.
