(E) If a Company shall, as a result of its ownership of any pledged stock, become entitled to receive or shall receive any stock certificate, stock option or similar rights in respect of the equity interests of any Subsidiary of the capital stock of any foreign Subsidiary that constitutes a Permitted Investment), whether in addition to, in substitution of, as a conversion of, or in exchange for, any shares of the pledged stock, or otherwise in respect thereof, such Company shall accept the same as the agent of the Agent, hold the same in trust for the Agent and deliver the same forthwith to the Agent, duly indorsed by such Company to the Agent, or accompanied by an undated stock power covering such certificate duly executed in blank by such Company, to be held by the Agent, subject to the terms hereof, as additional collateral security for the Secured Obligations (provided that in no event shall there be pledged more than 65% of any series of the outstanding capital stock of any foreign Subsidiary pursuant to this Agreement). Any sums paid upon or in respect of the pledged stock upon the liquidation or dissolution of any issuer thereof (except any liquidation or dissolution of any Subsidiary of KiOR permitted by the Credit Agreement) shall be paid over to the Agent, subject to the terms hereof as additional collateral security for the Secured Obligations.

6.8 Subsidiaries. The Company shall notify Agent and the Purchasers of each Subsidiary formed subsequent to the First Closing and, within fifteen (15) business days of formation, shall cause any such Subsidiary organized under the laws of any State within the United States (other than Subsidiaries of foreign Subsidiaries) to execute and deliver to Agent and the Purchasers a Joinder Agreement. The Company shall take such actions as reasonably requested by Agent to perfect the security interest of the Agent in the stock of any such Subsidiary as and to the extent provided herein.

6.9 Certain After-Acquired Collateral; Insurance.

(A) After Acquired Property. Without limiting the provisions of Section 6.3, the Company shall promptly notify Agent and the Purchasers in writing if, after the First Closing, the Company obtains any interest in any Collateral consisting of Deposit Accounts, securities accounts, investment accounts, or registered Intellectual Property, and, upon Agent’s or the Purchasers’ request, shall promptly take such actions as Agent or the Purchasers deem appropriate to effect Agent’s duly perfected, first priority Lien upon such Collateral; provided, however, that with respect to obtaining Account Control Agreements in favor of Agent over any securities account or investment account, the Company shall only be required to use commercially reasonable efforts; provided, further, that the Company shall not establish any new Deposit Account without giving 15 days’ (or such shorter period as Agent may agree) prior notice thereof to the Agent.

All certificates of insurance with respect to the Collateral will provide for a minimum of thirty (30) days advance written notice to Agent of cancellation (except for 10 days for nonpayment), or other evidence of notice of cancellation reasonably acceptable to the Agent. Any failure of Agent to scrutinize such insurance certificates for compliance is not a waiver of Agent’s rights, all of which are reserved. Notwithstanding anything to the foregoing contained in this Section, no breach of this Section 6.2 shall be deemed to have occurred unless (i) 60 days has lapsed from the date of this Agreement, and (ii) the requirements stated in this Section are not satisfied.

ARTICLE 7

RESTRICTIONS ON TRANSFERABILITY OF SECURITIES

7.1 Restrictions on Transferability.

(A) The Notes shall not be sold, transferred, assigned or hypothecated by the Purchasers under any circumstances (except in connection with a Change in Control or to a Permitted Transferee). Except as provided above, and subject to Section 7.1(B) and to any requirements of Regulation S that may be applicable to non-U.S. persons, the Notes shall not be sold, transferred, assigned or hypothecated unless (i) there is an effective registration statement under the Securities Act covering such Notes, (ii) the sale is made in accordance with Rule 144 under the Securities Act, or (iii) KiOR receives an opinion of counsel for the holder of the Notes reasonably satisfactory to KiOR stating that such sale, transfer, assignment or hypothecation is exempt from the registration requirements of the Securities Act, and each such case upon all other conditions specified in this Section 7.1. Furthermore, with respect to Notes that were initially sold by KiOR in reliance on Regulation S, hedging transactions involving such Notes may not be conducted unless in compliance with the Securities Act. Notwithstanding the provisions of the preceding sentence, no registration statement or opinion of counsel shall be required for any transfer of any Notes by a Purchaser to a Permitted Transferee; provided, that the proposed transferee of the Notes held by the Purchaser agrees in writing to take and hold such Notes subject to the provisions and upon the conditions specified in this Article 7. For purposes of this Agreement and the other Transaction Documents, upon a transfer of Notes to a Permitted Transferee, or otherwise in accordance with this Section 7.1, the applicable Permitted Transferee or transferee shall be deemed to be the “Purchaser” of such Note(s) and to have made each representation of a Purchaser under this Agreement and the other Transaction Documents.

(B) Any transfer not made in compliance with the requirements of this Section 7.1 shall be null and void ab initio, shall not be recorded on the books of KiOR or its transfer agent and shall not be recognized by KiOR. Each Purchaser acknowledges and agrees that any breach of this Section 7.1 by a Purchaser would result in substantial harm to KiOR and its stockholders for which monetary damages alone could not adequately compensate. Therefore, each Purchaser unconditionally and irrevocably agrees that KiOR shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity (including without limitation, seeking specific performance or the rescission of purchases, sales and other transfers of Notes not made in compliance with this Section 7.1).

REMEDIES

The following provisions in this Article 9 shall apply:

9.1 General. Upon and during the continuance of any one or more Events of Default, without the approval of any Purchaser, (i) Agent may, (and shall upon the written direction of the Required Purchasers) accelerate and demand payment of all or any part of the Secured Obligations and declare them to be immediately due and payable (provided, that upon the occurrence of an Event of Default of the type described in Section 8.5 (other than Section 8.5(A)(vi)), the Notes and all of the Secured Obligations shall automatically be accelerated and made due and payable, in each case without any further notice or act), and (ii) Agent may (and shall upon the written direction of the Required Purchasers) notify any of the Company’s account debtors to make payment directly to Agent (for the Pro Rata benefit of the Purchasers), compromise the amount of any such account on the Company’s behalf and endorse Agent’s name without recourse on any such payment for deposit directly to Agent’s account. Agent may (and shall upon the written direction of The Required Purchasers) exercise all rights and remedies with respect to the Collateral under the Transaction Documents or otherwise available to it under the UCC and other applicable law, including the right to release, hold, sell, lease, liquidate, collect, realize upon, or otherwise dispose of all or any part of the Collateral and the right to occupy, utilize, process and commingle the Collateral. All of Agent’s and each Purchaser’s rights and remedies shall be cumulative and not exclusive.

9.2 Collection; Foreclosure. Upon the occurrence and during the continuance of any Event of Default, Agent may (and shall upon the written direction of The Required Purchasers), at any time or from time to time, apply, collect, liquidate, sell in one or more sales, lease or otherwise dispose of, any or all of the Collateral, in its then condition or following any commercially reasonable preparation or processing, in such order as Agent may elect. Any such sale may be made either at public or private sale at its place of business or elsewhere. The Company agrees that any such public or private sale may occur upon ten (10) calendar days’ prior written notice to the Company. Agent may require the Company, at the Company’s expense, to assemble the Collateral and make it available to Agent at a place designated by Agent that is reasonably convenient to Agent. The proceeds of any sale, disposition or other realization upon all or any part of the Collateral shall be applied by Agent and the Purchasers in the following order of priorities:

First, to the Purchasers (on a Pro Rata basis) in an amount equal to the then unpaid amount of the Secured Obligations constituting the costs of collection;

Second, to the Purchasers (on a Pro Rata basis) in an amount equal to the then unpaid amount of the Secured Obligations constituting interest;

Third, to the Purchasers (on a Pro Rata basis) in an amount equal to the then unpaid amount of the Secured Obligations constituting principal;

Fourth, to the Purchasers in an amount equal to any other unpaid Secured Obligations (including Purchaser Expenses); and

- 32 -

Finally, after the full and final payment in Cash of all of the Secured Obligations, to any creditor holding a junior Lien on the Collateral, or to the Company or its representatives or as a court of competent jurisdiction may direct.

Agent and each Purchaser shall be deemed to have acted reasonably in the custody, preservation and disposition of any of the Collateral if it complies with the obligations of a secured party under the UCC.

9.3 No Waiver. Agent and each Purchaser shall be under no obligation to marshal any of the Collateral for the benefit of the Company or any other Person, and the Company expressly waives all rights, if any, to require Agent or any Purchaser to marshal any Collateral.

9.4 Cumulative Remedies. The rights, powers and remedies of Agent and each Purchaser hereunder shall be in addition to all rights, powers and remedies given by statute or rule of law and are cumulative. The exercise of any one or more of the rights, powers and remedies provided herein shall not be construed as a waiver of or election of remedies with respect to any other rights, powers and remedies of Agent or any Purchaser.

9.5 License. Agent is hereby granted an irrevocable, non-exclusive license or other right to use, license or sub-license (without payment of royalty or other compensation to any Person) any or all Intellectual Property of the Company, computer hardware and software, trade secrets, brochures, customer lists, promotional and advertising materials, labels, packaging materials and other property, in advertising for sale, marketing, selling, collecting, completing manufacture of, or otherwise exercising any rights or remedies with respect to, any Collateral. The Company’s rights and interests under Intellectual Property shall inure to Agent’s benefit. Notwithstanding the foregoing, Agent shall not be entitled to exercise any such license right or interest unless an Event of Default has occurred and is continuing and Agent is exercising its rights and remedies hereunder.

9.6 Power of Attorney. The Company hereby irrevocably constitutes and appoints Agent (and all Persons designated by Agent) as the Company’s true and lawful attorney (and agent-in-fact) for the purposes provided in this Section 9.6. Agent, or Agent’s designee, may, without notice and in either its or the Company’s name, but at the cost and expense of the Company, during the continuance of an Event of Default: (a) endorse the Company’s name on any proceeds of Collateral (including proceeds of insurance) that come into Agent’s possession or control; (b) notify any account debtors of the assignment of their Accounts, demand and enforce payment of Accounts by legal proceedings or otherwise, and generally exercise any rights and remedies with respect to Accounts; (c) settle, adjust, modify, compromise, discharge or release any Accounts or other Collateral, or any legal proceedings brought to collect Accounts or Collateral; (d) sell or assign any Accounts and other Collateral upon such terms, for such amounts and at such times as Agent deems advisable; (e) collect, liquidate and receive balances in Deposit Accounts, securities accounts or investment accounts, and take control, in any manner, of proceeds of Collateral; (f) prepare, file and sign the Company’s name to a proof of claim or other document in a bankruptcy of an account debtor, or to any notice, assignment or satisfaction of Lien or similar document; (g) receive, open and dispose of mail addressed to the Company, and notify postal authorities to deliver any such mail to an address designated by Agent; (h) endorse any Chattel Paper, Document, Instrument, bill of lading, or other document or agreement relating to any Accounts, Inventory or other Collateral; (i) use the Company’s stationary and sign its name to verifications of Accounts and notices to account debtors; (j) use information contained in any data processing, electronic or information systems relating to Collateral; (k) make and adjust claims under insurance policies; (l) take any action as may be necessary or appropriate to obtain payment under any letter of credit, banker’s acceptance or other instrument for which the Company is a beneficiary; and (m) take any and all appropriate actions and execute and deliver any and all documents and instruments which may be necessary to accomplish the purposes of this Agreement and the other Transaction Documents.

ARTICLE 11

AGENT

11.1 Appointment and Authority. Each Purchaser appoints and designates KFT Trust as Agent for the following purposes under all Transaction Documents, it being acknowledged and agreed that to the extent that Agent is a Purchaser hereunder, it shall be free to act in its capacity as Agent in its own self-interest without fiduciary obligations to the other Purchasers in exercising, or refraining from exercising, the rights granted to Agent hereunder. Agent shall have the sole and exclusive authority to (a) execute and deliver as Agent each Transaction Document, including any intercreditor or subordination agreement, and accept delivery of each Transaction Document from the Company or other Person; (b) act as collateral agent for Purchasers for purposes of perfecting and administering Liens under the Transaction Documents, and for all other purposes stated therein; (c) deal with Collateral; and (d) take any Enforcement Action or otherwise exercise any rights or remedies with respect to any Collateral under the Transaction Documents, applicable law or otherwise. The duties of Agent shall be ministerial and administrative in nature, and Agent shall not have a fiduciary relationship with any Purchaser or other Person by reason of any Transaction Document or any transaction relating thereto.

11.2 Duties. Agent shall not have any duties except those expressly set forth in the Transaction Documents. The conferral upon Agent of any right shall not imply a duty to exercise such right.

11.3 Agent Professionals. Agent may perform its duties through agents and employees. Agent may consult with and employ Agent Professionals, and shall be entitled to act upon, and shall be fully protected in any action taken in good faith reliance upon, any advice given by an Agent Professional. Agent shall not be responsible for the negligence or misconduct of any agents, employees or Agent Professionals selected by it with reasonable care.

11.4 Instructions of Required Purchasers. The rights and remedies conferred upon Agent under the Transaction Documents may be exercised without the necessity of joinder of any other party, unless required by applicable law. Agent may request instructions from Required Purchasers or other Purchasers with respect to any act (including the failure to act) in connection with any Transaction Documents, and may seek assurances to its satisfaction from Purchasers of their indemnification obligations against all claims that could be incurred by Agent in connection with any act. Agent shall be entitled to refrain from any act until it has received such instructions or assurances, and Agent shall not incur liability to any Person by reason of so refraining. Instructions of the Required Purchasers shall be binding upon Agent and all Purchasers (other than with respect to those actions to be taken, and decisions to be made, by the Agent which may be made and taken at the sole discretion of Agent as provided herein), and no Purchaser shall have any right of action whatsoever against Agent as a result of Agent acting or refraining from acting in accordance with the instructions of Required Purchasers. Notwithstanding the foregoing, instructions by and consent of specific parties shall be required to the extent provided in Section 10.3. In no event shall Agent be required to take any action that, in its opinion, is contrary to applicable law or any Transaction Documents or could subject any Agent Indemnitee to personal liability.

- 36 -

11.5 Lien Releases; Care of Collateral.

(A) Purchasers authorize Agent to release any Lien with respect to any Collateral (i) upon full and final cash payment of all Secured Obligations; (ii) that is the subject of an asset disposition to a non-party which the Company certify in writing to Agent is a Permitted Transfer or a Lien which the Company certifies is a Permitted Lien entitled to priority over Agent’s Liens and should not constitute Collateral under the terms hereof (and Agent may rely conclusively on any such certificate without further inquiry); (iii) that does not constitute a material part of the Collateral; or (iv) with the written consent of all Purchasers. Agent and the Purchasers agree that Agent shall at Company’s expense execute and deliver all documents reasonably requested by the Company to effect or otherwise evidence such release described above (and, if requested by Agent in connection with such execution and delivery, the Company shall certify to Agent that any applicable sale or disposition is being made in compliance with the terms of this Agreement (and Agent may rely conclusively on any such certificate, without further inquiry)). Any such release shall not in any manner discharge, affect or impair the Secured Obligations or any Liens (other than those expressly being released) upon (or obligations of the Company in respect of) all interests retained by the Company, including the proceeds of any sale, all of which shall continue to constitute part of the Collateral.

(B) Agent shall have no obligation to assure that any Collateral exists or is owned by the Company, or is cared for, protected or insured, nor to assure that Agent’s Liens have been properly created, perfected or enforced, or are entitled to any particular priority, nor to exercise any duty of care with respect to any Collateral.

11.6 Possession of Collateral. Agent and Purchasers appoint each other Purchaser as agent (for the benefit of Purchasers) for the purpose of perfecting Liens in any Collateral held or controlled by such Purchaser, to the extent such Liens are perfected by possession or control. If any Purchaser obtains possession or control of any Collateral, it shall notify Agent thereof and, promptly upon Agent’s request, deliver such Collateral to Agent or otherwise deal with it in accordance with Agent’s instructions.

11.7 Reliance By Agent. Agent shall be entitled to rely, and shall be fully protected in relying, upon any certification, notice or other communication (including those by telephone, telex, telegram, telecopy or e-mail) believed by it to be genuine and correct and to have been signed, sent or made by the proper Person, and upon the advice and statements of Agent Professionals. Agent shall have a reasonable and practicable amount of time to act upon any instruction, notice or other communication under any Transaction Document, and shall not be liable for any delay in acting.

11.8 Action Upon Default. Without limiting any of the rights of the Agent hereunder, Agent shall not be deemed to have knowledge of any Event of Default unless it has received written notice from the Company specifying the occurrence and nature thereof. Each Purchaser agrees that, except with the written consent of Agent, it will not take any Enforcement Action, or exercise any right that it might otherwise have under applicable law to credit bid at foreclosure sales, UCC sales or other similar dispositions of Collateral or to assert any rights relating to any Collateral.

11.9 Ratable Sharing. If any Purchaser shall obtain any payment or reduction of any Secured Obligation, whether through set-off or otherwise, in excess of its share of such Secured Obligation, determined on a Pro Rata basis or in accordance with Section 9.2, as applicable, such Purchaser shall forthwith purchase from Agent and the other Purchasers such participations in the affected Secured Obligation as are necessary to cause the purchasing Purchaser to share the excess payment or reduction on

- 37 -

a Pro Rata basis or in accordance with Section 9.2, as applicable. If any of such payment or reduction is thereafter recovered from the purchasing Purchaser, the purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest.

11.10 Indemnification. EACH PURCHASER SHALL INDEMNIFY AND HOLD HARMLESS AGENT INDEMNITEES, TO THE EXTENT NOT REIMBURSED BY THE COMPANY, ON A PRO RATA BASIS, AGAINST ALL INDEMNIFIED CLAIMS THAT MAY BE INCURRED BY OR ASSERTED AGAINST ANY SUCH AGENT INDEMNITEE, PROVIDED THAT ANY INDEMNIFIED CLAIM AGAINST AN AGENT INDEMNITEE RELATES TO OR ARISES FROM ITS ACTING AS OR FOR AGENT (IN THE CAPACITY OF AGENT). In Agent’s discretion, it may reserve for any claims made against an Agent Indemnitee, and may satisfy any judgment, order or settlement relating thereto, from proceeds of Collateral prior to making any distribution of Collateral proceeds to Purchasers. If Agent is sued by any receiver, bankruptcy trustee, debtor-in-possession or other Person for any alleged preference or fraudulent transfer, then any monies paid by Agent in settlement or satisfaction of such proceeding, together with all interest, costs and expenses (including attorneys’ fees) incurred in the defense of same, shall be promptly reimbursed to Agent by each Purchaser to the extent of its Pro Rata share.

11.11 Limitation on Responsibilities of Agent. Agent shall not be liable to any Purchaser for any action taken or omitted to be taken under the Transaction Documents, except for losses directly and solely caused by Agent’s gross negligence or willful misconduct as determined by a final, non-appealable judgment of a court of competent jurisdiction. Agent does not assume any responsibility for any failure or delay in performance or any breach by the Company or any Purchaser of any obligations under the Transaction Documents. Agent does not make any express or implied representation, warranty or guarantee to Purchasers with respect to any Secured Obligations, Collateral, Transaction Documents or the Company. No Agent Indemnitee shall be responsible to Purchasers for any recitals, statements, information, representations or warranties contained in any Transaction Documents; the execution, validity, genuineness, effectiveness or enforceability of any Transaction Documents; the genuineness, enforceability, collectability, value, sufficiency, location or existence of any Collateral, or the validity, extent, perfection or priority of any Lien therein; the validity, enforceability or collectability of any Secured Obligations; or the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of the Company. No Agent Indemnitee shall have any obligation to any Purchaser to ascertain or inquire into the existence of any Event of Default, the observance by the Company of any terms of the Transaction Documents, or the satisfaction of any conditions precedent contained in any Transaction Documents.

11.12 Resignation; Successor Agent. Subject to the appointment and acceptance of a successor Agent as provided below, Agent may resign at any time by giving at least ten (10) days written notice thereof to Purchasers and the Company. Upon receipt of such notice, KV III shall have the right to appoint a successor Agent which shall be a Purchaser or an Affiliate of a Purchaser and which shall be subject to the consent of KiOR (such consent not to be unreasonably withheld, delayed or conditioned and such consent not to be required if: (a) such successor Agent is an Affiliate of the retiring Agent, or (b) an Event of Default has occurred and is continuing). If no successor agent is appointed prior to the effective date of the resignation of Agent, then Agent may appoint a successor agent from among Purchasers (subject to the consent of KiOR (such consent not to be unreasonably withheld, delayed or conditioned and such consent not to be required if: (a) such successor Agent is an Affiliate of the retiring Agent, or (b) an Event of Default has occurred and is continuing)) or, if no Purchaser accepts such role or KiOR does not provide any necessary consent, Agent may appoint any of the Required Purchasers as successor Agent. Upon acceptance by a successor Agent of an appointment to serve as Agent hereunder, or upon appointment of a Required Purchaser as successor Agent, such successor Agent shall thereupon succeed to and become vested with all the powers and duties of the retiring Agent without further act, and the

- 38 -

retiring Agent shall be discharged from its duties and obligations hereunder but shall continue to have the benefits of the indemnification set forth in Section 11.10. Notwithstanding any Agent’s resignation, the provisions of this Section 11 shall continue in effect for its benefit with respect to any actions taken or omitted to be taken by it while Agent. Any successor to Agent by merger or acquisition of stock or this loan shall continue to be Agent hereunder without further act on the part of the parties hereto, unless such successor resigns as provided above.

11.13 Separate Collateral Agent. If Agent believes that it may be limited in the exercise of any rights or remedies under the Transaction Documents due to any applicable law, Agent may appoint an additional Person who is not so limited, as a separate collateral agent or co-collateral agent. If Agent so appoints a collateral agent or co-collateral agent, each right and remedy intended to be available to Agent under the Transaction Documents shall also be vested in such separate agent. Purchasers shall execute and deliver such documents as Agent deems appropriate to vest any rights or remedies in such agent. If any collateral agent or co-collateral agent shall die or dissolve, become incapable of acting, resign or be removed, then all the rights and remedies of such agent, to the extent permitted by applicable law, shall vest in and be exercised by Agent until appointment of a new agent.

11.14 Due Diligence and Non-Reliance. Each Purchaser acknowledges and agrees that it has, independently and without reliance upon Agent or any other Purchaser, and based upon such documents, information and analyses as it has deemed appropriate, made its own credit analysis of the Company and its own decision to enter into this Agreement. Without limiting Section 5.7, each Purchaser has made such inquiries as it feels necessary concerning the Transaction Documents, Collateral and the Company. Each Purchaser acknowledges and agrees that the other Purchasers have made no representations or warranties concerning the Company, any Collateral or the legality, validity, sufficiency or enforceability of any Transaction Documents or Secured Obligations. Each Purchaser will, independently and without reliance upon any other Purchaser, and based upon such financial statements, documents and information as it deems appropriate at the time, continue to make and rely upon its own credit decisions in taking or refraining from any action under any Transaction Documents. Except for notices, reports and other information expressly requested by a Purchaser, but subject to the limitations set forth in Section 11.16, Agent shall have no duty or responsibility to provide any Purchaser with any notices, reports or certificates furnished to Agent by the Company or any credit or other information concerning the affairs, financial condition, business or properties of the Company (or any of its Affiliates) which may come into possession of Agent or its Affiliates.

11.15 Recovery of Payments. If Agent pays any amount to a Purchaser in the expectation that a related payment will be received by Agent from the Company and such related payment is not received, then Agent may recover such amount from each Purchaser that received it. If Agent determines at any time that an amount received under any Transaction Document must be returned to the Company or paid to any other Person pursuant to applicable law or otherwise, then, notwithstanding any other term of any Transaction Document, Agent shall not be required to distribute such amount to any Purchaser. If any amounts received and applied by Agent to any Secured Obligations are later required to be returned by Agent pursuant to applicable law, each Purchaser shall pay to Agent, on demand, such Purchaser’s Pro Rata share of the amounts required to be returned.

11.16 Agent in its Individual Capacity. As a Purchaser, KV III (and any successor Agent that is a Purchaser) shall have the same rights and remedies under the other Transaction Documents as any other Purchaser, and the terms “Purchasers,” “Required Purchasers” or any similar term shall include KV III (and any such successor Agent that is a Purchaser) in its capacity as a Purchaser. In their individual capacities, Agent and its Affiliates may receive information regarding the Company and their Affiliates (including information subject to confidentiality obligations), and each Purchaser agrees that KV III and its Affiliates shall be under no obligation to provide such information to any Purchaser, if acquired in such individual capacity.

- 39 -

11.17 No Third Party Beneficiaries. This Section 11 is an agreement solely among Purchasers and Agent, and shall survive full and final payment in Cash of the Secured Obligations. This Section 11 (other than Section 11.5(a) and Section 11.12 (as it relates to Section 11.12, solely with respect to the Company’s consent rights contained therein)) does not confer any rights or benefits upon the Company or any other Person. As between the Company and Agent, any action that Agent may take under any Transaction Documents or with respect to any Secured Obligations shall be conclusively presumed to have been authorized and directed by Purchasers.

ARTICLE 12

GUARANTEE

12.1 Guarantee.

(A) Each Company (other than KiOR) hereby unconditionally and irrevocably guarantees, jointly and severally, to each Purchaser and their respective successors and assigns: (i) the full and punctual payment of principal of, premium and interest on the Notes when due, whether at maturity, by acceleration, by prepayment or otherwise, and all other monetary Secured Obligations of KiOR under this Agreement and the Notes; and (ii) the full and punctual performance within applicable grace periods of all other Secured Obligations of KiOR under this Agreement and the Notes.

(B) Each Company (other than KiOR) further agrees that the Secured Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Company and that such Company will remain bound under this Article 12 notwithstanding any extension or renewal of any Secured Obligation.

(C) Each Company (other than KiOR) waives presentation to, demand of, payment from and protest to KiOR of any of the Secured Obligations and also waives notice of protest for nonpayment. Each Company (other than KiOR) waives notice of any default under the Notes or the Secured Obligations. The Secured Obligations of each such Company hereunder shall not be affected by: (i) the failure of any Purchaser to assert any claim or demand or to enforce any right or remedy against KiOR or any other Person under this Agreement, the Notes or any other agreement or otherwise; (ii) any extension or renewal of any thereof; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Agreement, the Notes or any other agreement; (iv) the release of any security held by any Purchaser for the Secured Obligations or any of them; or (v) the failure of any of the Purchasers to exercise any right or remedy against any other guarantor of the Secured Obligations.

(D) Each Company (other than KiOR) further agrees that its guarantee pursuant to this Article 12 (each, a “Guarantee”) constitutes a Guarantee of payment and performance (and not merely a Guarantee of collection) and waives any right to require that any resort be had by any Purchaser or to any security held for payment of the Secured Obligations.

(E) The Secured Obligations of each Company (other than KiOR) hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Secured Obligations or otherwise (other than payment in full of the Secured Obligations other than contingent indemnification obligations and any other obligations which survive the payment of the Notes or the Additional Closing). Without limiting the generality of the foregoing, the

- 40 -

Secured Obligations of each Company (other than KiOR) herein shall not be discharged or impaired or otherwise affected by the failure of any Purchaser to assert any claim or demand or to enforce any remedy under this Agreement, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Secured Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Company or would otherwise operate as a discharge of such Company as a matter of law or equity.

(F) Each Company (other than KiOR) further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium or interest on any Secured Obligation is rescinded or must otherwise be restored by any Purchaser upon the bankruptcy or reorganization of KiOR or otherwise.

(G) In furtherance of the foregoing and not in limitation of any other right which any Purchaser has at law or in equity against any Company (other than KiOR) by virtue hereof, upon the failure of KiOR to pay the principal of or interest on any Secured Obligation when and as the same shall become due, whether at maturity, by acceleration, by prepayment or otherwise, each such Company hereby jointly and severally agrees to and shall, upon receipt of written demand by any Purchaser, forthwith pay, or cause to be paid, in cash, to each Purchaser an amount equal to the sum of: (i) the unpaid amount of such Secured Obligations; and (ii) accrued and unpaid interest on such Secured Obligations (but only to the extent not prohibited by law).

This Note is one of a series of Notes issued pursuant to that certain Senior Secured Promissory Note and Warrant Purchase Agreement dated March 31, 2014 among the Company, the Holder and certain other purchasers (as amended from time to time, the “Purchase Agreement”) and is entitled to the benefits of and is subject to the terms contained in that Purchase Agreement, including without limitation the security of the Purchase Agreement and the other Transaction Documents (as defined in the Purchase Agreement). Capitalized terms used but not defined herein shall have the meaning set forth in the Purchase Agreement.

(b) “Maturity Date” means any date elected by the Required Purchasers after July , 2014, provided that the Required Purchasers provides the Company with at least 10 days advance written notice of such date, and provided further that if the Required Purchasers shall not have provided such notice prior to March 31, 2017, then the Maturity Date shall be April 2, 2017.

2. Interest. The Principal Amount (which, for clarification, will include any PIK Interest) shall bear interest from the Closing Date at the Applicable Interest Rate based on a year consisting of 365 days, with interest computed daily based on the actual number of days elapsed.

2.1 Interest; Payments; PIK Interest. Company shall pay interest on the Principal Amount on the first day of each full calendar month, beginning on July , 2014, provided that interest may, at Company’s election, be paid as PIK Interest calculated at the Applicable Rate. The Principal Amount (which, for clarification, will include any previously paid PIK Interest) and all accrued but unpaid interest hereunder (including any PIK Interest), shall be due and payable on the Maturity Date. Company shall make all payments under this Agreement without setoff, recoupment or deduction and regardless of any counterclaim or defense. Payments to the Holder hereunder shall be made to the Holder at the account from time to time designated by the Holder by written notice to the Company.

2.2 Maximum Interest. Notwithstanding any provision in this Note, or any other Transaction Document, it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent jurisdiction shall deem applicable hereto (which under the laws of the State of New York shall be deemed to be the laws relating to permissible rates of interest on commercial loans) (the “Maximum Rate”). If a court of competent jurisdiction shall finally determine that Company has actually paid to Lenders an amount of interest in excess of the amount that would have been payable if all of the Secured Obligations had at all times borne interest at the Maximum Rate, then such excess interest actually paid by Company shall be applied as follows: first, to the payment of principal outstanding on all Notes; second, after all principal is repaid, to the payment of the Holder’s accrued interest, costs, expenses, professional fees and any other Secured Obligations; and third, after all Secured Obligations are repaid, the excess (if any) shall be refunded to the Company.

3. Maturity. The Principal Amount (which, for clarification, will include any previously paid PIK Interest) and all accrued but unpaid interest hereunder (including any PIK Interest) shall be due and payable by the Company on the Maturity Date.

4. Repayment on Change in Control. In the event that prior to the Maturity Date, the Company consummates a Change in Control, the Holder may, at the option of the Holder delivered in writing to the Company at least three (3) days prior to the Change in Control, require the Company to repay all or a portion of the Notes at a purchase price equal to the sum of (a) One Hundred and One percent (101%) of the Principal Amount (which, for clarification, will include any previously paid PIK Interest) and all accrued but unpaid interest hereunder (including any PIK Interest) (the “Adjusted Principal Amount”) and (b) the aggregate amount of Interest that would have been payable with respect to the Note had such Note not been repaid on such date, calculated from the date of such repayment as if the Principal Amount was the Adjusted Principal Amount, over the shorter of (i) a period of one year from the date of the consummation of the Change in Control and (ii) a period beginning on the date of the consummation of the Change in Control and ending on the Maturity Date.

5. Payment; Prepayment.

5.1 Payments. All payments shall be made in lawful money of the United States of America at the principal office of the Holder, or at such other place as the holder hereof may from time to time designate in writing to the Company. Payment shall be credited first to costs of collection if any, second to accrued interest due and payable and any remainder applied to principal. Prepayment of principal, together with accrued interest, may not be made prior to the Maturity Date without the consent of the Required Purchasers.

5.2 Prepayment. The Holder acknowledges and agrees that the payment and/or prepayment of all or any portion of the outstanding principal amount of this Note and all interest hereon shall be pari passu in right of payment and/or prepayment and in all other respects to the other Notes issued pursuant to the Purchase Agreement or pursuant to the terms of such Notes. In the event the Holder receives payments and/or prepayments in excess of its pro rata share of the Company’s payments and/or prepayments to the holders of all of the Notes, then the Holder shall hold in trust all such excess payments and/or prepayments for the benefit of the holders of the other Notes and shall pay such amounts held in trust to such other Holders upon demand by such Holders.

The Company will give prompt written notice to the Holder of the occurrence of any and all Events of Default.

7. Governing Law. This shall be governed by, and construed and enforced in accordance with, the laws of the State of New York, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction.

8. Titles and Subtitles. The titles and subtitles used in this Note are used for convenience only and are not to be considered in construing or interpreting this Note.

9. Amendments and Waivers. The amendment or waiver of any term of this Note, the resolution of any controversy or claim arising out of or relating to this Note and the provision of notice shall be conducted pursuant to the terms of the Purchase Agreement.

10. Severability. If any provision of this Note is held to be unenforceable under applicable law, such provision shall be excluded from this Note and the balance of the Note shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms.

11. Counterparts. This Note may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.

SECTION 2. Subordination; Priority of Liens.

2.1 Subordination; Etc. Notwithstanding the date, manner or order of grant, attachment or perfection of any Liens securing the Second-Lien Obligations granted on the Collateral or of any Liens securing the First-Lien Obligations granted on the Collateral or any actual or alleged defect in any of the foregoing, and notwithstanding any provision of the UCC, any other applicable law, this Agreement, the First-Lien Credit Documents or the Second-Lien Loan Documents to the contrary, or any other circumstance whatsoever, the Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, and each other Second-Lien Claimholder (by its acceptance of the benefits of the Second-Lien Loan Documents) hereby agrees that: (a) any Lien on the Collateral securing any First-Lien Obligations now or hereafter held by or on behalf of a First-Lien Agent or any First-Lien Creditor or any agent or trustee therefor, regardless of how acquired, whether by grant, possession, statute, operation of law, subrogation or otherwise, shall be senior in all respects and prior to any Lien on the Collateral securing any of the Second-Lien Obligations; (b) any Lien on the Collateral now or hereafter held by or on behalf of the Second-Lien Agent, any Second-Lien Claimholder or any agent or trustee therefor regardless of how acquired, whether by grant, possession, statute, operation of law, subrogation or otherwise, shall be junior and subordinate in all respects to all Liens on the Collateral securing any First-Lien Obligations, and (c) it will not take or cause to be taken any action the purpose or effect of which is, or could be, to make any Lien securing the Second-Lien Obligations pari passu with, or to give the Second-Lien Agent or Second-Lien Claimholders any preference or priority relative to, any Lien securing the First-Lien Obligations with respect to the Collateral or any part thereof. All Liens on the Collateral securing any First-Lien Obligations shall be and remain senior in all respects and prior to all Liens on the Collateral securing any Second-Lien Obligations for all purposes, whether or not such Liens securing any First-Lien Obligations are subordinated to any Lien securing any other obligation of the Parent, any other Grantor or any other Person. The parties hereto acknowledge and agree that it is their intent that (i) the First-Lien Obligations (and the security therefor) constitute a separate and distinct class (and separate and distinct claims) from the Second-Lien Obligations (and the security therefor) and (ii) the grant of Liens securing payment and performance of the First-Lien Obligations and the grant of Liens securing payment and performance of the Second-Lien Obligations are two separate grants and create two separate and distinct Liens with each such Lien securing only the First-Lien Obligations or the Second-Lien Obligations, as the case may be.

2.2 Prohibition on Contesting Liens. Each of the Second-Lien Agent, for itself and on behalf of each Second-Lien Claimholder, and the First-Lien Agent, for itself and on behalf of each applicable First-Lien Creditor, agrees that it shall not (and hereby waives any right to) take any action to challenge or contest, or support any other Person in contesting or challenging, in any proceeding (including any Insolvency or Liquidation Proceeding), (i) the validity or enforceability of any Security Document or any obligation thereunder, (ii) the validity, perfection, priority or enforceability of the Liens, mortgages, assignments and security interests

granted pursuant to the Security Documents with respect to the First-Lien Obligations or the Second-Lien Obligations or (iii) the relative rights and duties of the holders of the First-Lien Obligations and the Second-Lien Obligations granted and established in this Agreement or any other Security Document with respect to such Liens, mortgages, assignments, and security interests; provided that nothing in this Agreement shall be construed to prevent or impair the rights of either First-Lien Agent or, to the extent provided in Section 3, any First-Lien Creditor to enforce this Agreement, including the priority of the Liens securing the First-Lien Obligations as provided in Section 2.1 hereof.

2.3 No New Liens; Non-Collateral Assets. (a) So long as the Discharge of First-Lien Obligations has not occurred, the parties hereto agree that the Parent shall not, and shall not permit any other Grantor or Subsidiary to, (i) grant or permit any additional Liens, or take any action to perfect any Liens, on any asset or property to secure any Second-Lien Obligation unless it has also granted or contemporaneously grants to the First-Lien Agents a Lien on such asset or property to secure the First-Lien Obligations and has taken or is contemporaneously taking all actions to perfect such Liens in favor of the First-Lien Agents or (ii) grant or permit any additional Liens, or take any action to perfect any Liens, on any asset or property to secure any First-Lien Obligation unless it has also granted or contemporaneously grants to the Second-Lien Agent a Lien on such asset or property to secure the Second-Lien Obligations and has taken or is contemporaneously taking all actions to perfect such Liens in favor of the Second-Lien Agent; provided that the Parent shall provide notice to each Agent if a First-Lien Agent or the Second-Lien Agent has been granted a security interest or becomes perfected with respect to any additional Liens on any asset or property to secure any First-Lien Obligations or the Second-Lien Obligations, as applicable, and in such event, the Parent or such other Grantor or Subsidiary, as applicable, shall contemporaneously grant such additional Liens, or take such additional action as is necessary to perfect any Liens so granted, in favor of a First-Lien Agents or the Second-Lien Agent, as applicable. To the extent that the foregoing provisions are not complied with for any reason, without limiting any other rights and remedies available to the First-Lien Agents and the other First-Lien Creditors, the Second-Lien Agent, on behalf of itself and the other Second-Lien Claimholders, and each other Second-Lien Claimholder (by its acceptance of the benefits of the Second-Lien Loan Documents), shall, without the need for any further consent of any other Person and notwithstanding anything to the contrary in any other Second-Lien Loan Document hold and be deemed to have held such Lien for the benefit of the First-Lien Agent as security for the First-Lien Obligations (and all amounts received by or distributed to any of them pursuant to or as a result of the Liens granted in contravention of this Section 2.3 shall be subject to Section 4.2). All proceeds of such additional Collateral shall in any event be applied in accordance with this Agreement. It is acknowledged and agreed that certain actions with respect to the perfection of Collateral in favor of the First-Lien Agents may be completed by the Grantors after the date hereof as agreed in the First-Lien Credit Documents, and until such time, there shall not be a breach of this Agreement as a result of the Second-Lien Agent but not a First-Lien Agent, being perfected.

(b) The First-Lien Agents and the Second-Lien Agent acknowledge and agree there may be certain limited assets of the Grantors that constitute Non-Collateral Assets at a particular time of reference. In connection therewith, the First-Lien Agents and the Second-Lien Agent further acknowledge and agree that, in the event that a First-Lien Agent exercises its rights to

perfect a Lien in all or any portion of the Non-Collateral Asset, from and after the date upon which a First-Lien Agent or the Second-Lien Agent takes steps to perfect its Lien therein, such other Non-Collateral Asset (or the applicable portion thereof) shall constitute Collateral for all purposes hereof and shall no longer be Non-Collateral Assets hereunder. Upon the perfection of its Lien in any such Non-Collateral Asset by a First-Lien Agent, the Parent or applicable Grantor shall grant to the Second-Lien Agent and the other First-Lien Agent a Lien on such Non-Collateral Asset and cooperate with the Second-Lien Agent and the other First-Lien Agent in order to perfect such Lien in favor of the Second-Lien Agent, with any such Lien to be subject to the terms of this Agreement, in the case of the Second-Lien Agent, and to be subordinate to the Lien in such Collateral in favor of the First-Lien Agents on the same basis as the other Liens securing the First-Lien Obligations.

2.4 Similar Liens and Agreements. The parties hereto agree that it is their intention that the Second-Lien Collateral shall not be more expansive than, and shall be, except to the extent provided herein, identical to, the First-Lien Collateral. In furtherance of the foregoing and of Section 8.9 hereof, the parties hereto agree, subject to the other provisions of this Agreement:

(i) to cooperate in good faith (and to direct their counsel to cooperate in good faith) from time to time in order to determine the specific items included in the First-Lien Collateral and the Second-Lien Collateral and the steps taken to perfect the Liens thereon and the identity of the Persons having First-Lien Obligations and Second-Lien Obligations;

(ii) to make the form, documents and agreements creating or evidencing the First-Lien Collateral and the Second-Lien Collateral materially the same, other than with respect to the first and second lien nature of the liens and the priorities hereunder; and

(iii) that any Subsidiary of the Parent that is a borrower, guarantor or co-obligor under the First-Lien Purchase Agreement shall also be a guarantor or co-obligor of the Second-Lien Obligations and vice versa.

2.5 Payment Subordination. Without limiting the foregoing provisions of this Section 2, and notwithstanding any other provision of this Agreement, the parties hereto agree as follows:

(a) Subordination. The payment of any and all of the Second-Lien Obligations is hereby expressly subordinated, to the extent and in the manner set forth herein, to the Discharge of First-Lien Obligations. Each First-Lien Creditor, whether now outstanding or hereafter arising, shall be deemed to have acquired First-Lien Obligations in reliance upon the provisions contained herein. The parties hereto intend that this Agreement be enforceable in any Insolvency or Liquidation Proceeding.

(b) Restriction on Payments. Notwithstanding any provision of the Second-Lien Loan Documents to the contrary, no payment (whether made in cash, securities or other property or by set-off) of principal, interest or any other amount due with respect to the Second-Lien Obligations shall be made or received, and no Second-Lien Claimholder shall exercise any right of set-off or recoupment with respect to any Second-Lien Obligations, until the Discharge

of First-Lien Obligations; provided, however, except as provided in the immediately succeeding sentence or in Section 2.5(c) and subject to the provisions of Section 2.5(d), any Grantor may make and each Second-Lien Claimholder may accept Permitted Second-Lien Payments; and provided, further, that nothing in this Agreement shall be construed to prohibit or to require the consent of Parent or of any First Lien Creditor to the conversion of all or any portion of the Second-Lien Obligations in accordance with the terms of the Second-Lien Loan Documents. Notwithstanding the foregoing, no Grantor may make, and no Second-Lien Claimholder may receive:

(i) any payment of principal, interest or any other amount with respect to the Second-Lien Obligations if, at the time of such payment or immediately after giving effect thereto, a Senior Payment Default exists and the Second-Lien Claimholders shall have received a Senior Default Notice specifying such existence; provided that nothing in this clause (i) shall limit a Second-Lien Claimholder’s obligations under Section 2.5(d); or

(ii) subject to the penultimate sentence of this Section 2.5(b), any payment of principal, interest or any other amount with respect to the Second-Lien Obligations if, at the time of such payment or immediately after giving effect thereto, the Second-Lien Claimholders shall have received a Senior Default Notice from a First-Lien Agent stating that a Senior Covenant Default exists or would be created by the making of such payment.

The Grantors may resume Permitted Second-Lien Payments (and may make any Permitted Second-Lien Payments) missed due to the application of clause (i) or clause (ii) of this Section 2.5(b)):

A. in the case of a Senior Payment Default referred to in clause (i) of this Section 2.5(b), upon the cure or waiver thereof in accordance with the terms of the First-Lien Purchase Agreement; or

B. in the case of a Senior Covenant Default referred to in clause (ii) of this Section 2.5(b), upon the earlier to occur of (x) the cure or waiver thereof in accordance with the terms of the First-Lien Purchase Agreement, and (y) the expiration of 180 days from the date on which the applicable Senior Default Notice was received.

Notwithstanding any provision of this Section 2.5(b) to the contrary:

(1) no Senior Covenant Default existing on the date any notice is given pursuant to clause (ii) of this Section 2.5(b) shall, unless the same shall have ceased to exist for a period of at least ninety (90) consecutive days, be used as a basis for any subsequent such notice; and

(2) no more than two (2) Senior Default Notices may be sent pursuant to clause (ii) of this Section 2.5(b) during any consecutive 365 day period and no more than six (6) Senior Default Notices may be sent pursuant to clause (ii) of this Section 2.5(b) during the term of this Agreement.

The provisions of this Section 2.5(b) shall not apply to any payment with respect to which Section 2.5(c) would be applicable. For purposes of clarification, the term “payment” does not include the accrual of interest, fees or other amounts under the Second-Lien Loan Documents.

(i) In the event of any Insolvency or Liquidation Proceeding with respect to any Grantor or any of its properties: (i) the Discharge of First-Lien Obligations shall occur before any payment (whether made in cash, securities or other property) of or with respect to the Second-Lien Obligations shall be made by, or from the assets or estate of, such Grantor (other than Permitted Subordinated Securities); and (ii) any payment which, but for the terms hereof, otherwise would be payable or deliverable in respect of the Second-Lien Obligations (other than Permitted Subordinated Securities), shall be paid or delivered directly to First-Lien Agents (to be applied by First-Lien Agents in accordance with the terms of the First-Lien Purchase Agreement to the repayment of any and all then outstanding First-Lien Obligations) until Discharge of First-Lien Obligations, and each Second-Lien Claimholder irrevocably authorizes, empowers and directs all receivers, trustees, liquidators, custodians, conservators and others having authority in the premises to effect all such payments and deliveries.

(ii) If any holder of Second-Lien Obligations has not filed any proof of claim or other instrument of similar character necessary to enforce the obligations of any Grantor in respect of the Second-Lien Obligations (a “Proof of Claim”) held by such holder within fifteen (15) days before the expiration of the time to file the same, then and in such event, but only in such event, First-Lien Agent may notify such holder of such fact which notification must be in writing and include a statement to the effect that such First-Lien Agent may pursuant to this Section 2.5(c), if such Proof of Claim is not so filed by such holder of Second-Lien Obligations at least five (5) days before the expiration of the time to file the same, as an attorney-in-fact for such holder of Second-Lien Obligations, file such Proof of Claim on behalf of such holder of Second-Lien Obligations. At any time within five (5) days prior to the expiration of the time to file such Proof of Claim, if such holder of Second-Lien Obligations has not so filed the same, a First-Lien Agent may (if it has complied with the notice provisions in the immediately preceding sentence), as attorney-in-fact for such holder of Second-Lien Obligations and at the expense of the Grantors, file such Proof of Claim and such holder of Second-Lien Obligations appoints such First-Lien Agent as an attorney-in-fact for such holder of Second-Lien Obligations, to so file any such Proof of Claim; provided, that such First-Lien Agent shall have no obligation to make any such filings. In the event a First-Lien Agent makes any filing in accordance with the authority granted hereby, no holder of Second-Lien Obligations shall be entitled to amend or otherwise modify such filing except solely to the extent necessary to correct any factual errors. Notwithstanding the foregoing, the holders of Second-Lien Obligations shall nevertheless retain, exclusively, all rights to enforce and to vote all Proofs of Claim and otherwise to act in any Insolvency or Liquidation Proceeding in their capacity as such holders of Second-Lien Obligations (including the right to vote to accept or reject any plan of reorganization, composition, arrangement or liquidation) to the fullest extent provided by applicable law but subject to the terms of Sections 2.5 and Section 6.

(iii) The First-Lien Obligations shall continue to be treated as First-Lien Obligations and the provisions of this Agreement shall continue to govern the relative rights and priorities of each Agent, the First-Lien Creditors and the Second-Lien Claimholders even if

all or part of the First-Lien Obligations or the Liens securing the First-Lien Obligations are subordinated, set aside, avoided or disallowed in connection with any such Insolvency or Liquidation Proceeding, other than as a result of a ruling by a court of competent jurisdiction, in a final and non-appealable judgment, that the First-Lien Obligations is equitably subordinated to the Second-Lien Obligations as a result of the bad faith or willful misconduct of the holders of First-Lien Obligations but only to the extent that such determination results in the Second-Lien Claimholders recovering less in such Insolvency or Liquidation Proceeding than such Person would have recovered had the First-Lien Obligations not been equitably subordinated. This Agreement shall be reinstated if at any time any payment of any of the First-Lien Obligations is rescinded or must otherwise be returned by any holder of the First-Lien Obligations or any representative of such holder and the First-Lien Obligations, or portion thereof, intended to have been satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred.

(d) Incorrect Payments. If (a) any payment (whether made in cash, securities or other property) not permitted under this Agreement is received by any Second-Lien Claimholder on account of the Second-Lien Obligations before the Discharge of First-Lien Obligations, or (b) any payment (whether made in cash, securities or other property (other than Permitted Subordinated Securities)) is received by any Second-Lien Claimholder on account of the Second-Lien Obligations when a Senior Payment Default exists and such Second-Lien Claimholder is notified of such Senior Payment Default within ten (10) days after the date on which such payment of Second-Lien Obligations was scheduled to be made, then each such payment (including any subsequent payment in respect of the Second-Lien Obligations made during the continuation of such Senior Payment Default) shall be paid over promptly to First-Lien Agent, or its designated representative, for application (in accordance with the First-Lien Purchase Agreement) to the payment of the First-Lien Obligations then remaining unpaid, until the Discharge of the First-Lien Obligations.

(e) Restriction on Action by Second-Lien Claimholders. Until the Discharge of First-Lien Obligations has occurred, no Second-Lien Claimholder shall, without the prior written consent of First-Lien Agent, take any action to collect, enforce payment or accelerate any of the Second-Lien Obligations, exercise any of the remedies with respect to the Second-Lien Obligations set forth in any of the Second-Lien Loan Documents or that otherwise may be available to any Second-Lien Claimholder, either at law or in equity, by judicial proceedings (including by filing an Insolvency or Liquidation Proceeding) or otherwise (an “Enforcement Action”), except that (x) upon the occurrence and during the continuance of an event of default under the Second-Lien Loan Documents, the Second-Lien Claimholders may deliver to the Grantors a notice of acceleration provided such acceleration is not effective until the earliest of the dates specified in clause (i) through (iv) below, (y) the Second-Lien Claimholders may take legal action seeking specific performance or injunctive relief against any Grantor to enforce covenants (other than covenants to pay any of the Second-Lien Obligations) contained in the Second-Lien Loan Documents; provided that such action does not require the making of any payments to the Second-Lien Claimholders, and (z) as provided in the following sentence. Upon the earliest to occur of:

(i) the passage of 180 days from the earlier of (a) the date of a First-Lien Agent’s receipt of a notice that an event of default has occurred under the Second-Lien Loan Documents if the event of default described therein shall not have been cured or waived within such period in accordance with the Second-Lien Loan Documents or (b) the date on which a Senior Default Notice is given effectuating a payment block pursuant to Section 2.5(b);

(ii) final maturity of all then outstanding First-Lien Obligations (by acceleration or otherwise);

(iii) the occurrence of an Insolvency or Liquidation Proceeding with respect to any Grantor;

(iv) the institution or commencement by First-Lien Agent of any action to foreclose upon any material portion of the First-Lien Collateral; or

(v) the stated final maturity of the Second-Lien Obligations (i.e., February 1, 2016 or such later date as the Second-Lien Claimholders and the Grantors may expressly agree in writing and otherwise in accordance with the terms of the Second-Lien Loan Agreement),

the Second-Lien Claimholders may, upon five (5) Business Days’ prior written notice to First-Lien Agent, in respect of Enforcement Actions taken pursuant to clause (i) above, which notice may be given during such 180-day period, take Enforcement Actions; provided, that in the event the Second-Lien Claimholders shall be permitted to take Enforcement Actions solely as a result of the occurrence of an Insolvency or Liquidation Proceeding with respect to any Grantor(s) pursuant to clause (ii) above, such Enforcement Actions may only be taken with regard to such Grantor(s) and, for purposes of clarification, not with respect to any other Grantors.

SECTION 3. Enforcement.

3.1 Exercise of Remedies. Without limiting the provisions of Section 2.5: (a) So long as the Discharge of First-Lien Obligations has not occurred, whether or not any Insolvency or Liquidation Proceeding has been commenced by or against the Parent or any other Grantor: (i) the Second-Lien Agent and the other Second-Lien Claimholders will not exercise or seek to exercise any rights or remedies (including setoff) as a secured creditor with respect to any Collateral (including, without limitation, the exercise of any right under any lockbox agreement, control account agreement, landlord waiver or bailee’s letter or similar agreement or arrangement to which the Second-Lien Agent or any Second-Lien Claimholder is a party or holds a perfected interest through the Control Agent) or institute or commence, or join with any Person in commencing, any action or proceeding against the Parent or any other Grantor with respect to such rights or remedies (including any action of foreclosure, enforcement, collection or execution), and will not contest, protest, seek to enjoin or object to any foreclosure proceeding or action brought by a First-Lien Agent or any other First-Lien Creditor or any other exercise by a First-Lien Agent or any other First-Lien Creditor, of any rights and remedies relating to the Collateral under the First-Lien Credit Documents or otherwise, or contest, protest, seek to enjoin or object to the forbearance by a First-Lien Agent or the other First-Lien Creditors from bringing or pursuing any foreclosure proceeding or action or any other exercise of any rights or remedies relating to the Collateral; and (ii) First-Lien Agents shall have the exclusive right to enforce rights, exercise remedies (including setoff and the right to credit bid their debt) and make

determinations regarding the release, disposition, or restrictions with respect to the Collateral without any consultation with or the consent of the Second-Lien Agent or any other Second-Lien Claimholder; provided, that, (A) subject to Section 2.5(c), in any Insolvency or Liquidation Proceeding commenced by or against the Parent or any other Grantor, the Second-Lien Agent may file a proof of claim or statement of interest with respect to the Second-Lien Obligations, (B) the Second-Lien Agent may take any action (not adverse to the priority of the First-Lien Obligations and Liens on the Collateral securing the First-Lien Obligations, or the rights, remedies and claims of the First-Lien Agents or the other First-Lien Creditors) in order to preserve, perfect or protect (but not enforce) its Lien on the Collateral in a manner not otherwise inconsistent with the terms of this Agreement, (C) the Second-Lien Claimholders shall be entitled to file any necessary responsive or defensive pleading in opposition to any motion, claim, adversary proceeding or other pleading made by any Person objecting to or otherwise seeking the disallowance of the claims of the Second-Lien Claimholders, including any claim secured by the Collateral, if any, in each case in a manner not otherwise inconsistent with the terms of this Agreement and not adverse to the priority of the First-Lien Obligations and Liens on the Collateral securing the First-Lien Obligations or the rights, remedies and claims of the First-Lien Agents or other First-Lien Creditor, (D) the Second-Lien Claimholders shall be entitled to file any pleadings, objections, motions or agreements which assert rights or interests available to unsecured creditors of the Grantors arising under either Bankruptcy Law or applicable non-bankruptcy law, in each case subject to the terms of this Agreement (including, without limitation, Sections 2.5 and 5.4 hereof) and in accordance with the terms of this Agreement, (E) the Second-Lien Claimholders shall be entitled to join (but not exercise any control over) a judicial foreclosure or Lien enforcement proceeding with respect to the Collateral initiated by First-Lien Agent, to the extent that such action could not reasonably be expected to interfere materially with such foreclosure or proceeding, but no Second-Lien Claimholder may receive any proceeds thereof unless expressly permitted herein, and (E) the Second-Lien Claimholders shall be entitled to bid for or purchase Collateral at any public, private, or judicial foreclosure upon such Collateral initiated by any First-Lien Creditor, or any sale of Collateral during an Insolvency or Liquidation Proceeding; provided that such bid may not include a “credit bid” in respect of any Second-Lien Obligations unless the proceeds of such bid are otherwise sufficient to cause the Discharge of First-Lien Obligations. In exercising rights and remedies with respect to the Collateral, the First-Lien Agent and the other First-Lien Creditors may enforce the provisions of the First-Lien Credit Documents and exercise remedies thereunder, all in such order and in such manner as they may determine in the exercise of their sole discretion. Such exercise and enforcement shall include the rights of an agent appointed by them to sell or otherwise dispose of Collateral upon foreclosure, to incur expenses in connection with such sale or disposition, and to exercise all the rights and remedies of a secured creditor under the UCC of any applicable jurisdiction and of a secured creditor under Bankruptcy Laws of any applicable jurisdiction.

(b) Notwithstanding the preceding Section 3.1(a), but subject to Section 2.5, Second-Lien Claimholders may exercise any rights or remedies (including setoff) as a secured creditor with respect to any Collateral or exercise rights with respect to a Lien securing a Second-Lien Obligation if (i) 180 days have elapsed since Second-Lien Agent notified First-Lien Agents that the Second-Lien Obligations were due in full as a result of acceleration or otherwise (the “Standstill Period”), (ii) the First- Lien Creditors are not then diligently pursuing any applicable

remedy with respect to all or a material portion of the Collateral or diligently attempting to vacate any stay or prohibition against such exercise, (iii) any acceleration of the Second-Lien Obligations has not been rescinded, and (iv) no Grantor is not then a debtor in an Insolvency or Liquidation Proceeding.

(c) The Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, agrees that it will not take or receive any Collateral or any proceeds of Collateral in connection with the exercise of any right or remedy (including setoff or recoupment) with respect to any Collateral, and that any Collateral or proceeds taken or received by it will be paid over to the First-Lien Agent pursuant to Sections 2.5(d) and 4.2, unless and until the Discharge of First-Lien Obligations has occurred. Without limiting the generality of the foregoing, unless and until the Discharge of First-Lien Obligations has occurred, the rights of the Second-Lien Agent and the other Second-Lien Claimholders with respect to the Collateral are limited to the right to hold a Lien on the Collateral pursuant to the Second-Lien Security Documents for the period and to the extent granted therein, to receive a share of the proceeds thereof, if any, in accordance with the terms of the Second-Lien Loan Documents and applicable law, after the Discharge of First-Lien Obligations has occurred, and to exercise only such other rights as are expressly permitted herein.

(c) Subject to the proviso in clause (ii) of Section 3.1(a), the Second-Lien Agent, for itself and on behalf of the Second-Lien Claimholders, and each other Second-Lien Claimholder (by its acceptance of the benefits of the Second-Lien Loan Documents), (i) agrees that the Second-Lien Agent and the other Second-Lien Claimholders will not take any action that would enjoin, hinder, delay, limit or prohibit any exercise of remedies under the First-Lien Credit Documents, including any collection, sale, lease, exchange, transfer or other disposition of the Collateral, whether by foreclosure or otherwise, or that would limit, invalidate, avoid or set aside any Lien or First-Lien Security Document or subordinate the priority of the First-Lien Obligations to the Second-Lien Obligations or grant the Liens securing the Second-Lien Obligations equal ranking to the Liens securing the First-Lien Obligations and (ii) hereby waives any and all rights it or the Second-Lien Claimholders may have as a junior lien creditor or otherwise (whether arising under the UCC or under any other law) to object to the manner in which a First-Lien Agent or the other First-Lien Creditors seek to enforce or collect the First-Lien Obligations or the Liens granted in any of the First-Lien Collateral, regardless of whether any action or failure to act by or on behalf of a First-Lien Agent or First-Lien Creditors is adverse to the interest of the Second-Lien Claimholders.

(d) The Second-Lien Agent hereby acknowledges and agrees that no covenant, agreement or restriction contained in the Second-Lien Security Documents or any other Second-Lien Loan Document shall be deemed to restrict in any way the rights and remedies of the First-Lien Agent or the other First-Lien Creditors with respect to the Collateral as set forth in this Agreement and the First-Lien Credit Documents.

(e) Cooperation. Subject to its rights after the expiration of the Standstill Period and subject to the proviso in clause (ii) of Section 3.1(a) of this Agreement, the Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, agrees that, unless and until the Discharge of First-Lien Obligations has occurred, it will not commence, or join with any Person in

commencing, any enforcement, collection, execution, levy or foreclosure action or proceeding (including, without limitation, pursuant to any Insolvency or Liquidation Proceeding) with respect to any Lien held by it under the Second-Lien Security Documents or any other Second-Lien Loan Document or otherwise.

3.2 Actions Upon Breach. (a) If any Second-Lien Claimholder, contrary to this Agreement, commences or participates in any action or proceeding against any Grantor with respect to the Collateral or against the Collateral, any First-Lien Creditor may intervene and interpose as a defense or dilatory plea the making of this Agreement, in its name or in the name of such Grantor.

(b) Should any Second-Lien Claimholder or First-Lien Creditor, contrary to this Agreement, in any way take, attempt to or threaten to take any action with respect to the Collateral (including, without limitation, any attempt to realize upon or enforce any remedy with respect to this Agreement), or take any other action in violation of this Agreement or fail to take any action required by this Agreement, a First-Lien Agent or the Second-Lien Agent, as applicable, (in its own name or in the name of the relevant Grantor), or any other First-Lien Creditor or Second-Lien Claimholders, as applicable, with the prior written consent of the applicable Agent, (i) may obtain relief against such First-Lien Creditor or Second-Lien Claimholder by injunction, specific performance or other appropriate equitable relief, it being understood and agreed by the parties that (x) the non-breaching party’s damages from the actions of the breaching party may at that time be difficult to ascertain and may be irreparable, and (y) each such breaching party waives any defense that the non-breaching party cannot demonstrate damage or be made whole by the awarding of damages, and (ii) shall be entitled to damages from the breaching parties, as well as reimbursement for all reasonable and documented costs and expenses incurred in connection with any action to enforce the provisions of this Agreement.

SECTION 4. Payments.

4.1 Application of Proceeds. So long as the Discharge of First-Lien Obligations has not occurred, any proceeds of any Collateral pursuant to the enforcement of any Security Document or the exercise of any remedial provision thereunder, together with all other proceeds of Collateral received by any Creditor (including all funds received in respect of post-petition interest or fees and expenses) as a result of any such enforcement or the exercise of any such remedial provision or as a result of any distribution of or in respect of any Collateral or under a plan of reorganization upon or in any Insolvency or Liquidation Proceeding with respect to any Grantor, or the application of any Collateral (or proceeds thereof) to the payment thereof or any distribution of Collateral (or proceeds thereof) upon the liquidation or dissolution of any Grantor, shall be applied by the First-Lien Agents to the First-Lien Obligations in such order as specified in the relevant First-Lien Security Document. Upon the Discharge of First-Lien Obligations, the First-Lien Agents shall deliver to the Second-Lien Agent any proceeds of Collateral held by them in the same form as received, with any necessary endorsements or as a court of competent jurisdiction may otherwise direct, to be applied by the Second-Lien Agent to the Second-Lien Obligations in such order as specified in the Second-Lien Security Documents.

4.2 Payment Turnover. Until such time as the Discharge of First-Lien Obligations has occurred, any Collateral or proceeds thereof (including any distribution in respect of the Collateral) received by the Second-Lien Agent or any other Second-Lien Claimholders in connection with the exercise of any right or remedy (including setoff or recoupment) relating to the Collateral or in connection with any insurance policy claim or any condemnation award (or deed in lieu of condemnation) or that is otherwise inconsistent with this Agreement (including Section 2.5 hereof) shall be segregated and held in trust and promptly paid over to a First-Lien Agent for the benefit of the First-Lien Creditors in the same form as received, with any necessary endorsements or as a court of competent jurisdiction may otherwise direct. Each First-Lien Agent is hereby authorized to make any such endorsements as agent for the Second-Lien Agent or any such other Second-Lien Claimholders. This authorization is coupled with an interest and is irrevocable until such time as this Agreement is terminated in accordance with its terms.

SECTION 5. Other Agreements.

5.1 Releases of Liens.

(a) If, in connection with:

(i) the exercise of the First-Lien Agents’ remedies in respect of the Collateral provided for in Section 3.1 hereof, including any sale, lease, exchange, transfer or other disposition of any such Collateral;

(ii) any sale, lease, exchange, transfer or other disposition of any Collateral permitted or not prohibited under the terms of the First-Lien Credit Documents and the Second-Lien Loan Documents (whether or not an “event of default” thereunder or under any Second-Lien Loan Document has occurred and is continuing), whether by its terms or pursuant to any amendment thereto or consent or waiver thereunder; or

(iii) any agreement between a First-Lien Agent and any Grantor to release the First-Lien Agent’s Lien on any portion of the Collateral;

there occurs the release by each First-Lien Agent of any of its Liens on any part of the Collateral (each, a “First-Lien Release”), then the Liens, if any, of the Second-Lien Agent, for itself and for the benefit of the other Second-Lien Claimholders, on such Collateral shall be, except as otherwise provided in this Section 5.1(a), automatically, unconditionally and simultaneously released, and, upon receipt of notice in writing, the Second-Lien Agent, for itself or on behalf of any such Second-Lien Claimholders, promptly shall, except as otherwise provided in this Section 5.1(a), execute and deliver to the First-Lien Agents or such Grantor such termination statements, releases and other documents as the First-Lien Agents or such Grantor may request, and/or which the Grantor has provided to the Second-Lien Agent, to effectively confirm such release; provided, however, that, (i) if the Liens securing the First-Lien Obligations are released in connection with the Discharge of First-Lien Obligations (without a contemporaneous incurrence of new or replacement First-Lien Obligations), the Second-Priority Liens on the Collateral will not be required to be released (except to the extent the Collateral or any portion thereof was disposed of or otherwise transferred or used in order to repay the First-Lien Obligations secured

by the Collateral) and (ii) any release effected or occasioned by the terms of this Section 5.1 by Second-Lien Agent of any Lien in favor of Second-Lien Agent or any of the Second-Lien Claimholders shall not extend to or otherwise affect any of the rights of Second- Lien Collateral Agent or any Second-Lien Claimholder arising under the Second-Lien Loan Documents to any proceeds of any disposition of any Collateral occurring in connection with such First-Lien Release, provided that such rights to such proceeds shall be subject in all respects to the terms and conditions of this Agreement. In the case of the sale of capital stock of a Subsidiary or any other transaction resulting in the release of such Subsidiary as a borrower, guarantor or co-obligor under the First-Lien Purchase Agreement in accordance with the First-Lien Purchase Agreement (whether by its terms or pursuant to any amendment thereto or consent or waiver thereunder), the guarantee or other obligations in favor of the Second-Lien Claimholders, if any, made or incurred by such Subsidiary will automatically be released and discharged as and when, but only to the extent, such Subsidiary is released and discharged as a borrower, guarantor or co-obligor under the First-Lien Credit Documents.

(b) Until the Discharge of First-Lien Obligations occurs, the Second-Lien Agent, for itself and on behalf of the Second-Lien Claimholders, hereby irrevocably constitutes and appoints the First-Lien Agents and any officer or agent of either First-Lien Agent, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Second-Lien Agent or such other Second-Lien Claimholder or in the First-Lien Agent’s own name, from time to time in the First-Lien Agent’s discretion, for the purpose of carrying out the terms of this Section 5.1, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Section 5.1, including any endorsements or other instruments of transfer or release. This authorization is coupled with an interest and is irrevocable until such time as this Agreement is terminated in accordance with its terms.

5.2 Insurance. The First-Lien Agents (on behalf of the First-Lien Creditors) shall be named as first loss payee under all insurance policies maintained from time to time by any Grantor (other than liability policies) and the Second-Lien Agent (on behalf of the Second-Lien Claimholders) shall be named as the second loss payee on such policies of insurance. The First-Lien Agents and the Second-Lien Agent shall be named additional insureds on all liability insurance policies maintained from time to time by any Grantor. The First-Lien Agents will have the exclusive right to adjust settlement for any losses covered by an insurance policy covering the Collateral, and to approve an award granted in a condemnation or similar proceeding (or a deed in lieu of condemnation) affecting the Collateral. If the Second-Lien Agent or any other Second-Lien Claimholder shall, at any time, receive from the insurer any proceeds of any such insurance policy or any such award or payment in contravention of this Agreement, it shall pay such proceeds over to a First-Lien Agent in accordance with the terms of Sections 2.5(c) and 4.2 of this Agreement. It is acknowledged and agreed that certain actions with respect to insurance may be completed by the Grantors after the date hereof as agreed in the First-Lien Credit Documents, and until such time, there shall not be a breach of this Agreement as a result of non-compliance with this Section 5.2.

5.3 Amendments to Second-Lien Loan Documents and First-Lien Credit Documents.

(a) Without the prior written consent of the First-Lien Agents, no Second-Lien Loan Document may be amended, restated, supplemented, modified or Refinanced or entered into to the extent such amendment, supplement, restatement, modification or Refinancing, or the terms of any new Second-Lien Loan Document, would contravene the provisions or intent of this Agreement, the First-Lien Purchase Agreement, or any other First-Lien Credit Document (it being understood that the Second-Lien Agent may rely upon an opinion of counsel to the Parent to make any determination as to whether the requirements of this Section 5.3 have been complied with). The Parent, each other Grantor and the Second-Lien Agent each agree that each Second-Lien Security Document shall include the following language (or language to similar effect approved by the First-Lien Agents):

“Notwithstanding anything herein to the contrary, the Second-Lien Obligations and the lien and security interest granted to the Second-Lien Agent pursuant to this Agreement and the exercise of certain rights and remedies by the Second-Lien Agent hereunder are subordinated and subject to the provisions of that certain Amended and Restated Subordination Agreement, dated as of March 31, 2014 (as amended, restated, supplemented or otherwise modified from time to time in accordance with the terms thereof, the “Subordination Agreement”), among KiOR, Inc., the other Grantors from time to time party thereto, Khosla Ventures III LP, in its capacity as the initial First-Lien Agent under the 2013 First Lien Purchase Agreement, KFT Trust, Vinod Khosla, Trustee, in its capacity as the initial First-Lien Agent under the 2014 First Lien Purchase Agreement, and 1538731 Alberta Ltd., in its capacity as the initial Second-Lien Agent thereunder. In the event of any conflict between the terms of the Subordination Agreement and this Agreement, the terms of the Subordination Agreement shall govern and control.”

(b) Without limiting the foregoing provisions of Section 5.3(a), each Grantor, the First-Lien Agents (for itself and on behalf of each other First-Lien Creditor) and the Second-Lien Agent (for itself and on behalf of each other Second-Lien Claimholder) hereby agrees that, without the prior written consent of the First-Lien Agents, no Second-Lien Loan Document may be amended, restated, supplemented or otherwise modified, or entered into, to the extent such amendment, restatement, supplement or modification, or the terms of such new Second-Lien Loan Document, would (a) increase the principal amount of the Second-Lien Obligations in excess of the Maximum Second-Lien Principal Amount (other than as a result of the capitalization (and not payment in cash or cash equivalents) of any Permitted Second-Lien Payments), (b) require any payment of interest in cash until the final stated maturity of the Second-Lien Obligations or increase the applicable interest rate margins under the Second-Lien Loan Documents (including, for the avoidance of doubt, any pay-in-kind interest margins) by more than 300 basis points (excluding increases resulting from the accrual of interest at the default rate), (c) change to earlier dates any scheduled dates for payment of principal (including the final maturity date) or of interest on Indebtedness under the Second-Lien Loan Documents, (d) change any default or event of default provisions set forth in the Second-Lien Loan Documents in a manner materially adverse to the First-Lien Creditors, (e) change the prepayment provisions set forth in the Second-Lien Loan Documents in a manner materially adverse to the

First-Lien Creditors, (f) add to the Collateral under the Second-Lien Loan Documents other than as specifically permitted by this Agreement or (g) otherwise materially increase the obligations of the Grantors or the other loan parties thereunder or confer additional rights on the Second-Lien Claimholders in a manner materially adverse to the First-Lien Creditors. The Second-Lien Obligations may be Refinanced, in whole or in part and without the consent of the First-Lien Agent or any of the First-Lien Creditors, if (i) such Refinancing complies with the restrictions in the previous sentence, (ii) the final maturity and the average life to maturity of such Refinancing Indebtedness is at least equal to that of the Indebtedness then outstanding under the Second-Lien Loan Agreement and (iii) the holders of such Refinancing Indebtedness, or a duly authorized agent on their behalf, agree in writing to be bound by the terms of this Agreement.

(c) In the event the First-Lien Agents or the other First-Lien Creditors and the relevant Grantor(s) enter into any amendment, restatement, waiver or consent in respect of any of the First-Lien Security Documents for the purpose of adding to, or deleting from, or waiving or consenting to any departures from any provisions of, any First-Lien Security Document or changing in any manner the rights of the First-Lien Agent, the other First-Lien Creditors, the Parent or any other Grantor thereunder, then such amendment, restatement, waiver or consent shall apply automatically to any comparable provision of the Comparable Second-Lien Security Document without the consent of the Second-Lien Agent or the other Second-Lien Claimholders and without any action by the Second-Lien Agent, the Parent or any other Grantor, provided, that (A) any such amendment, restatement, waiver or consent that is prejudicial to the rights of the Second-Lien Claimholders (other than by virtue of their relative priorities and rights and obligations hereunder) and does not affect the First-Lien Agent or the other First-Lien Creditors in a like or similar manner shall not apply to the Comparable Second-Lien Security Document without the consent of the Second-Lien Agent, it being agreed that any release contemplated by Section 5.1 hereof shall be deemed not to be prejudicial to the rights of the Second-Lien Claimholders, (B) written notice of such amendment, restatement, waiver or consent shall have been given to the Second-Lien Agent no less than five Business Days prior to the effectiveness thereof (although the failure to give any such notice shall in no way affect the effectiveness of any such amendment, waiver or consent), (C) no such modification may, without the prior consent of the Second-Lien Agent, release any Second-Lien Collateral, except to the extent such release is otherwise permitted or required hereby (including Section 6.1) and there is a corresponding release of First-Lien Collateral and (D) no such modification will, without the prior consent of the Second-Lien Agent, impose any additional duties on the Second-Lien Agent.

(d) Without the prior written consent of the Second-Lien Agent, no First-Lien Credit Document may be amended, restated, supplemented or otherwise modified or Refinanced or entered into to the extent such amendment, supplement, restatement, modification or Refinancing, or the terms of any new First-Lien Credit Documents, would (a) amend or modify the terms, as in effect on the date hereof, of the mandatory conversion to Equity Interests of the First-Lien Obligations in a manner materially adverse to the Second-Lien Claimholders, including without limitation: (i) any conversion of the First-Lien Obligations into Equity Interests other than common stock of the Parent; (ii) any modification of the conversion price formula in a manner that would yield a lower conversion price compared to such formula in the absence of such modification; and (iii) any increase in the aggregate dollar amount of the Financing Event, as defined in First-Lien Credit Documents, (b) increase the principal amount

(excluding paid in kind interest) of the First Lien Obligations issued under the 2014 First Lien Purchase Agreement to an aggregate amount in excess of $25,000,000, (c) require any payment of interest in cash until the final stated maturity of the First-Lien Obligations or increase the applicable interest rate margins under the First-Lien Loan Documents (including, for the avoidance of doubt, any pay-in-kind interest margins) by more than 300 basis points (excluding increases resulting from the accrual of interest at the default rate), or (d) change to earlier dates any scheduled dates for payment of principal (including the final maturity date) or of interest on Indebtedness under the First-Lien Loan Documents. Without the prior written consent of the Second-Lien Agent, the Intercreditor Agreement of even date herewith by and between the 2013 First Lien Agent and the 2014 First Lien Agent shall not be restated, supplemented or otherwise modified to change the pari passu treatment of the 2013 Debt or the 2014 Debt (as such terms are defined therein) for all purposes, including payment and recourse to collateral, under the 2013 First Lien Purchase Agreement and the 2014 First Lien Purchase Agreement. Without the consent of the Second-Lien Agent, no party hereto or any affiliate thereof shall take any action having the result that the term loans under the Second Lien Purchase Agreement in the original principal amount of $75 million shall not remain and be treated as pari passu for all purposes, including, without limitation, with respect to right and priority of payment and recourse to collateral.

5.4 Rights As Unsecured Creditors. Except as otherwise set forth in this Agreement (including Section 2.5 hereof), the Second-Lien Agent and the other Second-Lien Claimholders may exercise rights and remedies as unsecured creditors against any Grantor in accordance with the terms of the Second-Lien Loan Documents and applicable law, it being agreed by the Second-Lien Agent (on behalf of itself and the Second-Lien Claimholders) that the waivers and other agreements made herein by the Second-Lien Agent (on behalf of itself and the Second-Lien Claimholders) shall bind it (and each of the Second-Lien Claimholders) in their capacity as an unsecured creditor. Except as otherwise set forth in this Agreement (and subject in any event to any lien subordination provisions in the Second-Lien Loan Agreement and the other Second-Lien Loan Documents), nothing in this Agreement shall prohibit the receipt by the Second-Lien Agent or any other Second-Lien Claimholder of payments on the Second-Lien Obligations so long as such receipt is not (i) the direct or indirect result of the exercise by the Second-Lien Agent or any other Second-Lien Claimholder of rights or remedies as a secured creditor with respect to the Collateral (including setoff or recoupment) or enforcement in contravention of this Agreement of any Lien held by any of them or (ii) otherwise in contravention of this Agreement. In the event the Second-Lien Agent or any other Second-Lien Claimholder becomes a judgment lien creditor in respect of Collateral as a result of any enforcement of its rights, such judgment lien shall be subordinated to the Liens securing First-Lien Obligations on the same basis as the other Liens securing the Second-Lien Obligations are so subordinated to such Liens securing First-Lien Obligations under this Agreement. Nothing in this Agreement impairs or otherwise adversely affects any rights or remedies the First-Lien Agent or the other First-Lien Creditors may have with respect to the First-Lien Collateral.

5.5 Control Agent for Perfection. (a) Each First-Lien Agent, on behalf of itself and the applicable First-Lien Creditors, and the Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, each hereby appoint (i) KFT Trust, Vinod Khosla Trustee, as its collateral agent (in such capacity, together with any successor in such capacity from time to time,

the “KFT Control Agent”), (ii) Khosla Ventures III LP as its collateral agent (in such capacity, together with any successor in such capacity from time to time, the “KV Control Agent”) and (iii) 1538731 Alberta Ltd., as its collateral agent (in such capacity, together with any successor in such capacity from time to time, the “AIMco Control Agent” and together with the KFT Control Agent and the KV Control Agent, each a “Control Agent”), in each case, for the limited purpose of acting as the agent on behalf of the First-Lien Agent (on behalf of itself and the First-Lien Creditors) and the Second-Lien Agent (on behalf of itself and the Second-Lien Claimholders) with respect to the Possessory Collateral and all, if any, Collateral consisting of deposit accounts, securities accounts or commodity accounts (the “Control Assets”), solely for purposes of perfecting the Liens of such parties on the Possessory Collateral and such Control Assets. Each Control Agent accepts such appointment and agrees to hold the Possessory Collateral and any Control Assets in its possession or control (or in the possession or control of its agents or bailees) as Control Agent for the benefit of the First-Lien Agent (on behalf of itself and the First-Lien Creditors) and the Second-Lien Agent (on behalf of itself and the Second-Lien Claimholders) and any permitted assignee of any thereof solely for the purpose of perfecting the security interest granted to such parties in such Possessory Collateral or Control Assets, subject to the terms and conditions of this Section 5.5 as gratuitous bailee and/or gratuitous agent for perfection for the benefit of the other Agent as secured party, so as to satisfy the requirements of sections 8-106(d)(3), 8-301(a)(2), and 9-313(c) of the U.C.C.

(b) Until the Discharge of First-Lien Obligations has occurred, the Control Agent, any First-Lien Agent (on behalf of itself and the First-Lien Creditors) and the Second-Lien Agent (on behalf of itself and the Second-Lien Claimholders) each hereby agrees that the applicable First-Lien Agent shall have the sole and exclusive authority to give instructions to, and otherwise direct, the Control Agent in respect of the Possessory Collateral and Control Assets (such instructions and directions to be consistent with this Agreement) and shall be entitled to deal with the Possessory Collateral and Control Assets in accordance with the terms of the First-Lien Credit Documents and this Agreement as if the Liens of the Second-Lien Agent under the Second-Lien Security Documents did not exist. The rights of the Second-Lien Agent shall at all times be subject to the terms of this Agreement and to the First-Lien Agent’s rights under the First-Lien Credit Documents and neither the Second-Lien Agent nor any Second-Lien Claimholder will impede, hinder, delay or interfere with the exercise of such rights by the First-Lien Agent in any respect. The Grantors hereby jointly and severally agree to pay, reimburse, indemnify and hold harmless the Control Agent to the same extent and on the same terms that the Grantors are required to do so for the First-Lien Agent in accordance with the First- Lien Credit Agreement. The First-Lien Creditors and the Second-Lien Claimholders hereby jointly and severally agree to pay, reimburse, indemnify and hold harmless the Control Agent to the same extent and on the same terms that the First-Lien Creditors are required to do so for the First-Lien Agent in accordance with the First-Lien Purchase Agreement and the Second-Lien Claimholders are required to do so for the Second-Lien Agent in accordance with the Second-Lien Loan Documents.

(c) The Control Agent shall have no obligation whatsoever to the First-Lien Creditors and the Second-Lien Agent or any Second-Lien Claimholder, including, without limitation, any obligation to assure that any of the Possessory Collateral or Control Assets is genuine or owned by any of the Grantors or to preserve rights or benefits of any Person except as expressly set

forth in this Section 5.5. In acting on behalf of the Second-Lien Agent and the Second-Lien Claimholders and the First-Lien Agents and the First-Lien Creditors, the duties or responsibilities of the First-Lien Agents under this Section 5.5 shall be limited solely (i) to physically holding or controlling (to the extent physical delivery has been made or control has been effected and has not been terminated by the applicable depository bank or securities intermediary) the Possessory Collateral or Control Assets delivered to the Control Agent by any Grantor as agent for the First-Lien Agents (on behalf of itself and the First-Lien Creditors) and the Second-Lien Agent (on behalf of itself and the Second-Lien Claimholders) for purposes of perfecting the Lien held by the First-Lien Agents and the Second-Lien Agent and (ii) delivering such collateral as set forth in Section 5.5(e).

(d) Neither the Control Agent nor any First-Lien Agent shall have by reason of the Second-Lien Loan Documents (including, without limitation, the Second-Lien Security Documents), the First-Lien Credit Documents (including, without limitation, the First-Lien Security Documents), this Agreement or any other document, a fiduciary relationship or any fiduciary duties in respect of the First-Lien Creditors, the Second-Lien Agent or any other Second-Lien Claimholder.

(e) Upon the Discharge of First-Lien Obligations, the Control Agent shall deliver whatever Possessory Collateral or Control Assets it has in its possession (if any) (or proceeds thereof) together with any necessary endorsements, first, to the Second-Lien Agent or as the Second-Lien Agent shall otherwise lawfully direct (solely to the extent such Possessory Collateral or Control Assets constitute Collateral), if any Second-Lien Obligations remain outstanding, and second, to the Parent or the relevant Grantor if no First-Lien Obligations or Second-Lien Obligations remain outstanding (in each case, so as to allow such Person to obtain control of such Possessory Collateral and Control Assets). The First-Lien Agent further agrees to take all other action reasonably requested by such Person, at such Parent’s sole cost and expense, in connection with such Person’s obtaining a first-priority interest in the Collateral or as a court of competent jurisdiction may otherwise direct. Without limiting the foregoing, upon the Discharge of First-Lien Obligations, at the request of the Parent or the Second-Lien Agent, the First-Lien Agent will use commercially reasonable efforts to promptly deliver an appropriate termination or other notice confirming such Discharge of First-Lien Obligations to the applicable depositary bank, issuer of uncertificated securities or securities intermediary, if any, with respect to deposit account collateral, money market mutual fund or similar collateral, or securities account collateral.

(f) The Control Agent shall have an unfettered right to resign as Control Agent upon 30 days’ notice to the First-Lien Agents and the Second-Lien Agent. If upon the effective date of such resignation no successor to the Control Agent has been appointed by the First-Lien Agents and the Second-Lien Agent, the Control Agent shall deliver to a First-Lien Agent the Possessory Collateral and Control Assets, together with any necessary endorsements (or otherwise allow the First-Lien Agent to obtain control of such Possessory Collateral and Control Assets) or as a court of competent jurisdiction may otherwise direct and the First-Lien Agent shall accept and succeed to the role of the Control Agent with respect to the Possessory Collateral and Control Assets, whereupon such First-Lien Agent shall assume all of the duties and comply with all of the obligations of the “Control Agent” as set forth in the foregoing clauses (a) through (e).

5.6 When Discharge of First-Lien Obligations Deemed to Not Have Occurred. If the Discharge of First-Lien Obligations occurs in connection with any Refinancing of the First-Lien Obligations, or if the Grantors subsequently incur First-Lien Obligations, then such Discharge of First-Lien Obligations shall automatically be deemed not to have occurred for all purposes of this Agreement, and the obligations under such Refinancing or subsequent First-Lien Obligations shall automatically be treated as “First-Lien Obligations” for all purposes of this Agreement, including for purposes of the Lien and payment priorities and rights in respect of Collateral set forth herein, and the agent under the First-Lien Credit Documents evidencing or relating to such Refinancing shall be a First-Lien Agent for all purposes of this Agreement (and, if there is no agent relating to such Refinancing, any lender, bank, or financial institution holding any obligations thereunder shall be deemed a First-Lien Agent for all purposes hereunder). Upon receipt of an officer’s certificate stating that the Parent or other Grantors have entered into Refinancing of the First-Lien Obligations (which certificate shall include the identity of the new agent, such agent, the “New Agent” and state that the Refinancing is permitted hereunder), the Second-Lien Agent shall promptly, at Parent’s sole cost and expense, enter into such documents and agreements (including amendments or supplements to this Agreement) as the Parent or such New Agent may reasonably request in order to provide to the New Agent the rights contemplated hereby, in each case consistent in all material respects with the terms of this Agreement. If the new First-Lien Obligations under the new First-Lien Credit Documents are secured by assets of the Grantors of the type constituting First-Lien Collateral that do not also secure the Second-Lien Obligations, then the Second-Lien Obligations shall be secured at such time by a second-priority lien on such assets to the same extent provided in the Second-Lien Loan Documents with respect to the other First-Lien Collateral. The Second-Lien Agent shall not be charged with knowledge of such reinstatement until it receives written notice from a First-Lien Agent, New Agent or the Parent of the occurrence of such reinstatement.

SECTION 6. Insolvency or Liquidation Proceedings.

6.1 Finance and Sale Issues. (a) Until the Discharge of the First-Lien Obligations has occurred, if the Parent or any other Grantor shall be subject to any Insolvency or Liquidation Proceeding and the First-Lien Agents shall desire to permit the use of Cash Collateral on which the First-Lien Agent or any other creditor of the Parent or any other Grantor has a Lien or agrees to permit the Parent or any other Grantor to obtain post-petition financing (including on a priming basis), whether from the First-Lien Creditors or any other third party under Section 362, 363 or 364 of the Bankruptcy Code or any other Bankruptcy Law (each, a “Post-Petition Financing”), then, so long as the maximum principal amount of Indebtedness that may be outstanding from time to time in connection with such Post-Petition Financing shall not exceed an aggregate amount equal to $15,000,000 in excess of the Maximum First-Lien Principal Amount (plus the amount of any accrued paid in kind interest on the First Lien Obligations), the Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, and each Second-Lien Claimholder (by its acceptance of the benefits of the Second-Lien Loan Documents), agrees that it will not oppose, seek to enjoin or raise any objection to or contest (or join with or support any third party opposing, objecting to or contesting), such use of Cash Collateral or Post-Petition

Financing (or to the priming of, or to the granting of the Liens pari passu with, the Liens securing the Second-Lien Obligations; provided that the Liens granted in connection with such post-petition financing also prime, or are pari passu with, the Liens securing the First-Lien Obligations) and will not request adequate protection or any other relief in connection therewith that is inconsistent with Section 6.3 (except as expressly agreed in writing by the First-Lien Agents) and, to the extent the Liens securing the First-Lien Obligations are subordinated to or pari passu with such Post-Petition Financing incurred in compliance with this Section 6.1, the Liens of the Second-Lien Claimholders on the Collateral shall be deemed to be subordinated, without any further action on the part of any person or entity, to the Liens securing such Post-Petition Financing (and all Obligations relating thereto), and the Liens securing the Second-Lien Obligations shall have the same priority with respect to the Collateral relative to the Liens securing the First-Lien Obligations as if such Post-Petition Financing had not occurred.

(b) Until the Discharge of the First-Lien Obligations has occurred, the Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, and each Second-Lien Claimholder (by its acceptance of the benefits of the Second-Lien Loan Documents), agrees that it will raise no objection to, seek to enjoin, oppose or contest (or join with or support any third party opposing, objecting to or contesting), a sale or other disposition of any, or substantially all of the, Collateral free and clear of its Liens or other claims under Section 363 of the Bankruptcy Code if the First-Lien Creditors have consented to such sale or disposition of such assets (and their Liens thereon are simultaneously being released) so long as either (i) the Liens of Second-Lien Claimholders attach to the net proceeds thereof on the same basis and priority as the Liens held by the Second-Lien Claimholders on such Collateral, and the Liens remain subject to the terms of this Agreement or (ii) the proceeds of a disposition of Collateral received by a First-Lien Agent in excess of those necessary to achieve the Discharge of First-Lien Obligations, are distributed in accordance with the U.C.C. and applicable law. If requested by a First-Lien Agent in connection therewith, the Second-Lien Agent shall affirmatively consent to such a sale or disposition.

6.2 Relief from the Automatic Stay. Until the Discharge of First-Lien Obligations has occurred, the Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, and each Second-Lien Claimholder (by its acceptance of the benefits of the Second-Lien Loan Documents), agrees that none of them shall (i) seek relief, pursuant to Section 362(d) of the Bankruptcy Code or otherwise, from the automatic stay of Section 362(a) of the Bankruptcy Code or from any other stay in any Insolvency or Liquidation Proceeding in respect of the Collateral, without the prior written consent of each First-Lien Agent, or (ii) oppose any request by a First-Lien Agent or any First-Lien Creditor to seek relief from the automatic stay or any other stay in any Insolvency or Liquidation Proceeding, provided that the Second-Lien Agent shall not be prohibited, as a result of the foregoing, from exercising the rights provided to it under Section 6.3(b).

6.3 Adequate Protection. (a) The Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, and each Second-Lien Claimholder (by its acceptance of the benefits of the Second-Lien Loan Documents), agrees that none of them shall (i) oppose, object to or contest (or join with or support any third party opposing, objecting to or contesting) (a) any request by a First-Lien Agent or the other First-Lien Creditors for adequate protection in any

Insolvency or Liquidation Proceeding (or any granting of such request) or (b) any objection by a First-Lien Agent or the other First-Lien Creditors to any motion, relief, action or proceeding based on a First-Lien Agent or the other First-Lien Creditors claiming a lack of adequate protection or (ii) seek or accept any form of adequate protection under any of Sections 362, 363 or 364 of the Bankruptcy Code with respect to the Collateral, except as expressly provided in this Section 6.3.

(b) In any Insolvency or Liquidation Proceeding, if the First-Lien Creditors (or any subset thereof) are granted adequate protection in the form of additional collateral in connection with any use of Cash Collateral or Post-Petition Financing, then the Second-Lien Agent, on behalf of itself or any of the other Second-Lien Claimholders, may seek or request adequate protection in the form of a Lien on such additional collateral, which Lien will be subordinated to the Liens securing the First-Lien Obligations, such use of Cash Collateral or any Post-Petition Financing (and all Obligations relating thereto) on the same basis as the other Liens securing the Second-Lien Obligations are so subordinated to the First-Lien Obligations under this Agreement, the First-Lien Security Documents and the Second-Lien Security Documents.

6.4 No Waiver; Voting Rights. (a) Nothing contained herein shall prohibit or in any way limit a First-Lien Agent or any First-Lien Creditor from objecting on any basis in any Insolvency or Liquidation Proceeding or otherwise to any action taken by the Second-Lien Agent or any other Second-Lien Claimholder, including the seeking by the Second-Lien Agent or any other Second-Lien Claimholder of adequate protection or the assertion by the Second-Lien Agent or any other Second-Lien Claimholder of any of its rights and remedies under the Second-Lien Loan Documents or otherwise; provided, however, that this Section 6.4 shall not limit the rights of the Second-Lien Claimholders expressly provided under Section 3.1 or Section 6.3. Neither the First-Lien Agent nor any First-Lien Creditors shall object to or otherwise contest, and if necessary, will consent to, the adequate protection contemplated by Section 6.3(b).

(b) The Second-Lien Agent (on behalf of itself and the Second-Lien Claimholders) agrees that, in any Insolvency or Liquidation Proceeding, neither the Second-Lien Agent nor any other Second-Lien Claimholder shall support (or join with or support any party in doing so) any plan of reorganization or disclosure statement of any Grantor unless such disclosure statement and plan are not inconsistent with this Agreement and (x) provide for the Discharge of First-Lien Obligations (including all post-petition interest, fees and expenses as provided in Section 6.6 hereof) on the effective date of such plan of reorganization, or (y) is otherwise accepted by the class of holders of the First-Lien Obligations voting thereon. Subject to the foregoing, the Second-Lien Claimholders shall remain entitled to vote their claims in any such Insolvency or Liquidation Proceeding.

6.5 Avoidance Issues. If any First-Lien Creditor is required in any Insolvency or Liquidation Proceeding to disgorge or otherwise to turn over or otherwise pay to the estate of the Parent or any other Grantor any amount for any reason (a “Recovery”), then the First-Lien Obligations shall be reinstated to the extent of such Recovery and the First-Lien Creditors shall be entitled to a reinstatement of First-Lien Obligations with respect to all such recovered amounts. If this Agreement shall have been terminated prior to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release,

discharge, impair or otherwise affect the obligations of the parties hereto from such date of reinstatement. Any and all amounts received by the Second-Lien Agent or any Second-Lien Claimholder from or in respect of Collateral or the proceeds thereof on account of the Second-Lien Obligations after the termination of this Agreement shall, in the event of a reinstatement of this Agreement pursuant to this Section 6.5, be held in trust for and paid over to the First-Lien Agent for the benefit of the First-Lien Creditors, for application to the reinstated First-Lien Obligations. This Section 6.5 shall survive termination of this Agreement.

6.6 Post-Petition Interest. (a) Neither the Second-Lien Agent nor any other Second-Lien Claimholder shall oppose or seek to challenge any claim by the First-Lien Agent or any other First-Lien Creditor for allowance in any Insolvency or Liquidation Proceeding of First-Lien Obligations consisting of post-petition interest, fees, premiums, costs or expenses to the extent of the value of the Liens securing the First-Lien Obligations (it being understood and agreed that such value shall be determined without regard to the existences of any Liens securing the Second-Lien Obligations and that neither the Second-Lien Agent nor any other Second-Lien Claimholder shall oppose the positions taken by a First-Lien Agent with respect to value); it being further understood that neither First-Lien Agent nor any other First-Lien Creditor shall be entitled to post-petition interest relating to any Excess Amount. Regardless of whether any such claim for pre- or post-petition interest, fees, premiums, costs, expenses or other charges is allowed or allowable, and without limiting the generality of the other provisions of this Agreement, this Agreement is expressly intended to include and does include the “rule of explicitness” in that this Agreement expressly entitles the First-Lien Creditors, and is intended to provide the First-Lien Creditors with the right, to receive payment of all post-petition interest, fees, premiums, costs, expenses or other charges through distributions from the Collateral made pursuant to the provisions of this Agreement even though such interest, fees, costs, expenses or other charges are not allowed or allowable against the bankruptcy estate of the Parent or any other Grantor under Section 502(b)(2) or Section 506(b) of the Bankruptcy Code or under any other provision of the Bankruptcy Code or any other Bankruptcy Law.

(b) Without limiting the foregoing, it is the intention of the parties hereto that (and to the maximum extent permitted by law the parties hereto agree that) the First-Lien Obligations (and the security therefor) constitute a separate and distinct class (and separate and distinct claims) from the Second-Lien Obligations (and the security therefor).

6.7 Bankruptcy Code Section 1111(b)(2). The Second-Lien Agent, for itself and on behalf of the other Second-Lien Claimholders, waives any claim any such Second-Lien Claimholder may hereafter have against any First-Lien Creditor arising out of (a) the election by any First-Lien Creditor of the application of Section 1111(b)(2) of the Bankruptcy Code, or any comparable provision of any other Bankruptcy Law or (b) any use of cash collateral or financing arrangement, or any grant of a security interest in the Collateral, in any Insolvency or Liquidation Proceeding.

6.8 Limitations. Without limiting any other right, remedy or limitation in this Agreement in favor of the First-Lien Agents and the other First-Lien Creditors, so long as the Discharge of First-Lien Obligations has not occurred, without the express written consent of the First-Lien Agents, none of the Second-Lien Claimholders shall (or shall join with or support any

third party making, opposing, objecting or contesting, as the case may be), in any Insolvency or Liquidation Proceeding involving any Grantor, (i) oppose, object to or contest the determination of the extent of any Liens held by any of the First-Lien Creditors or the value of any claims of First-Lien Creditors under Section 506(a) of the Bankruptcy Code, (ii) assert or support any claim under Section 506(c) of the Bankruptcy Code senior to or on parity with the First-Lien Obligations for costs or expenses of preserving or disposing of any Collateral (provided that this clause will not preclude the Second-Lien Agent or the Second-Lien Claimholders from supporting a plan of reorganization permitted by Section 6.4(b)) or (iii) oppose, object to or contest the payment to the First-Lien Creditors of interest, fees, premiums, costs or expenses under Section 506(b) of the Bankruptcy Code.

SECTION 7. Reliance; Waivers; Etc.

7.1 Reliance. Other than any reliance on the terms of this Agreement, each First-Lien Agent, on behalf of itself and the applicable First-Lien Creditors under the applicable First-Lien Credit Documents, acknowledges that it and the other First-Lien Creditors have, independently and without reliance on the Second-Lien Agent or any other Second-Lien Claimholders, and based on documents and information deemed by them appropriate, made their own credit analysis and decision to enter into such First-Lien Credit Documents and be bound by the terms of this Agreement and they will continue to make their own credit decision in taking or not taking any action under any First-Lien Credit Document or this Agreement. The Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, acknowledges that it and the other Second-Lien Claimholders have, independently and without reliance on the First-Lien Agents or any other First-Lien Creditor, and based on documents and information deemed by them appropriate, made their own analysis and decision to enter into each of the Second-Lien Loan Documents and be bound by the terms of this Agreement and they will continue to make their own decision in taking or not taking any action under the Second-Lien Loan Documents or this Agreement.

7.2 No Warranties or Liability. Each First-Lien Agent, on behalf of itself and the applicable First-Lien Creditors under the applicable First-Lien Credit Documents, acknowledges and agrees that each of the Second-Lien Agent and the other Second-Lien Claimholders have made no express or implied representation or warranty, including with respect to the execution, validity, legality, completeness, collectability or enforceability of any of the Second-Lien Loan Documents, the ownership of any Collateral or the perfection or priority of any Liens thereon. The Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, acknowledges and agrees that each of the First-Lien Agent and the First-Lien Creditors have made no express or implied representation or warranty, including with respect to the execution, validity, legality, completeness, collectability or enforceability of any of the First-Lien Credit Documents, the ownership of any Collateral or the perfection or priority of any Liens thereon. The First-Lien Creditors will be entitled to manage and supervise their respective loans and extensions of credit under their respective First-Lien Credit Documents in accordance with law and as they may otherwise, in their sole discretion, deem appropriate. The First-Lien Agents and the First-Lien Creditors shall have no duty to the Second-Lien Agent or any of the Second-Lien Claimholders, to act or refrain from acting in a manner which allows, or results in, the occurrence or continuance of an event of default or default under any agreements with the Parent or any other Grantor (including under the First-Lien Credit Documents), regardless of any knowledge thereof which they may have or be charged with.

7.3 No Waiver of Priorities. (a) No right of the First-Lien Creditors, the Control Agent or the First-Lien Agents or any of them to enforce any provision of this Agreement or any First-Lien Credit Document shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Parent or any other Grantor or by any act or failure to act by any First-Lien Creditor or the First-Lien Agents, or by any noncompliance by any Person with the terms, provisions and covenants of this Agreement, any of the First-Lien Credit Documents or any of the Second-Lien Loan Documents, regardless of any knowledge thereof which the First-Lien Agents or the First-Lien Creditors, or any of them, may have or be otherwise charged with.

(b) Without in any way limiting the generality of the foregoing paragraph (but subject to the rights of the Parent and the other Grantors under the First-Lien Credit Documents and the rights of the Second-Lien Agent and the Second-Lien Claimholders expressly set forth in this Agreement), the First-Lien Creditors, the First-Lien Agents and any of them may, at any time and from time to time in accordance with the First-Lien Credit Documents and/or applicable law, without the consent of, or notice to, the Second-Lien Agent or any other Second-Lien Claimholder, without incurring any liabilities to the Second-Lien Agent or any other Second-Lien Claimholder and without impairing or releasing the priorities and other benefits provided in this Agreement (even if any right of subrogation or other right or remedy of the Second-Lien Agent or any Second-Lien Claimholders is affected, impaired or extinguished thereby) do any one or more of the following:

(i) make loans and advances to any Grantor or issue, guaranty or obtain letters of credit for account of any Grantor or otherwise extend credit to any Grantor, in any amount and on any terms, whether pursuant to a commitment or as a discretionary advance and whether or not any default or event of default or failure of condition is then continuing;

(ii) change the manner, place or terms of payment or change or extend the time of payment of, or amend, renew, exchange, increase or alter, the terms of any of the First-Lien Obligations or any Lien on any First-Lien Collateral or guaranty thereof or any liability of the Parent or any other Grantor, or any liability incurred directly or indirectly in respect thereof (including any increase in or extension of the First-Lien Obligations, without any restriction as to the amount, tenor or terms of any such increase or extension) or otherwise amend, renew, exchange, extend, modify or supplement in any manner any Liens held by a First-Lien Agent or any of the First-Lien Creditors, the First-Lien Obligations or any of the First-Lien Credit Documents;

(iii) sell, exchange, release, surrender, realize upon, enforce or otherwise deal with in any manner and in any order any part of the First-Lien Collateral or any liability of the Parent or any other Grantor to the First-Lien Creditors or a First-Lien Agent, or any liability incurred directly or indirectly in respect thereof;

(iv) settle or compromise any First-Lien Obligation or any other liability of the Parent or any other Grantor or any security therefor or any liability incurred directly or indirectly in respect thereof and apply any sums by whomsoever paid and however realized to any liability (including the First-Lien Obligations) in any manner or order;

(v) exercise or delay in or refrain from exercising any right or remedy against the Parent or any other Grantor or any other Person or with respect to any security, elect any remedy and otherwise deal freely with the Parent, any other Grantor or any First-Lien Collateral and any security and any guarantor or any liability of the Parent or any other Grantor to the First-Lien Creditors or any liability incurred directly or indirectly in respect thereof; and

(vi) release or discharge any First-Lien Obligation or any guaranty thereof or any agreement or obligation of any Grantor or any other person or entity with respect thereto.

(c) The Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, and each other Second-Lien Claimholder (by its acceptance of the benefits of the Second-Lien Loan Documents), agrees not to assert and hereby waives any right to demand, request, plead or otherwise assert or otherwise claim the benefit of, any marshalling, appraisal, valuation or other similar right that may otherwise be available under applicable law with respect to the Collateral or any other similar rights a junior secured creditor may have under applicable law.

7.4 Waiver of Liability. (a) The Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, hereby waives any claim against the Control Agent, any First-Lien Creditor or any First-Lien Agent, arising out of any and all actions which the Control Agent, the First-Lien Creditors or the First-Lien Agents may take or permit or omit to take with respect to: (i) the First-Lien Credit Documents (including, without limitation, any failure to perfect or obtain perfected security interests in the First-Lien Collateral), (ii) the collection of the First-Lien Obligations or (iii) the foreclosure upon, or sale, liquidation or other disposition of, any First-Lien Collateral. The Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, agrees that the Control Agent, the First-Lien Creditors and the First-Lien Agents have no duty, express or implied, fiduciary or otherwise, to them in respect of the maintenance or preservation of the First-Lien Collateral, the First-Lien Obligations or otherwise. Neither the Control Agent, the First-Lien Agents nor any First-Lien Creditor nor any of their respective directors, officers, employees or agents will be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so, or will be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Parent or any other Grantor or upon the request of the Second-Lien Agent, any other holder of Second-Lien Obligations or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. Without limiting the foregoing, each Second-Lien Claimholder by accepting the benefits of the Second-Lien Loan Documents agrees that neither the Control Agent, the First-Lien Agents nor any other First-Lien Creditor (in directing the Agent to take any action with respect to the Collateral) shall have any duty or obligation to realize first upon any type of Collateral or to sell, dispose of or otherwise liquidate all or any portion of the Collateral in any manner, including as a result of the application of the principles of marshaling or otherwise, that would maximize the return to any class of Creditors holding Obligations of any type (whether First-Lien Obligations or Second-Lien Obligations), notwithstanding that the order and timing of any such realization, sale, disposition or liquidation may affect the amount of proceeds actually received by such class of Creditors from such realization, sale, disposition or liquidation.

7.5 Obligations Unconditional. All rights, interests, agreements and obligations of the First-Lien Agents and the other First-Lien Creditors and the Second-Lien Agent and the other Second-Lien Claimholders, respectively, hereunder (including the payment and Lien priorities established hereby) shall remain in full force and effect irrespective of:

(a)

any lack of validity or enforceability of any First-Lien Credit Document or any Second-Lien Loan Document or any setting aside or avoidance of any Lien;

(b)

any change in the time, manner or place of payment of, or in any other terms of, all or any of the First-Lien Obligations or Second-Lien Obligations, or any amendment or waiver or other modification, including any increase in the amount thereof, whether by course of conduct or otherwise, of the terms of any First-Lien Credit Document or any Second-Lien Loan Document;

(c)

any exchange of any security interest in any Collateral or any other collateral, or any amendment, waiver or other modification, whether in writing or by course of conduct or otherwise, of all or any of the First-Lien Obligations or Second-Lien Obligations or any guarantee thereof;

(d)

the commencement of any Insolvency or Liquidation Proceeding in respect of the Parent or any other Grantor; or

(e)

any other circumstances which otherwise might constitute a defense available to, or a discharge of, the Parent or any other Grantor in respect of the First-Lien Obligations, or of the Second-Lien Agent or any Second-Lien Claimholder in respect of this Agreement.

7.6 Certain Notices. (a) Promptly upon the satisfaction of the conditions set forth in clauses (a), (b), (c) and (d) of the definition of Discharge of First-Lien Obligations, the First-Lien Agents will endeavor to deliver written notice confirming same to the Second-Lien Agent; provided that the failure to give any such notice shall not result in any liability of the First-Lien Agents or the First-Lien Creditors hereunder or in the modification, alteration, impairment, or waiver of the rights of any party hereunder.

(b) Promptly upon (or as soon as practicable following) the commencement by a First-Lien Agent of any enforcement action or the exercise of any remedy with respect to, in each case, any Collateral (including by way of a public or private sale of Collateral), the First-Lien Agent will endeavor to notify the Second-Lien Agent of such action; provided that the failure to give any such notice shall not result in any liability of the First-Lien Agent or the First-Lien Creditors hereunder or in the modification, alteration, impairment, or waiver of the rights of any party hereunder.

SECTION 8. Miscellaneous.

8.1 Conflicts. In the event of any conflict between the provisions of this Agreement and the provisions of the First-Lien Credit Documents or the Second-Lien Loan Documents, the provisions of this Agreement shall govern and control. Without limitation of the foregoing, notwithstanding any waivers by the Second-Lien Claimholders of liabilities and/or duties of the Second-Lien Agent, none of such waivers shall be effective with respect to the rights of the First-Lien Agents or the First-Lien Creditors under this Agreement.

8.2 Effectiveness; Continuing Nature of this Agreement; Severability. This Agreement shall become effective when executed and delivered by the parties hereto. This is a continuing agreement of payment and lien subordination and the First-Lien Creditors may continue, at any time and without notice to the Second-Lien Agent or any other Second-Lien Claimholder, to extend credit and other financial accommodations and lend monies to or for the benefit of the Parent or any other Grantor constituting First-Lien Obligations in reliance hereon. The Second-Lien Agent, on behalf of itself and the other Second-Lien Claimholders, hereby agrees that it will not attempt, directly or indirectly, whether by judicial proceedings or otherwise, to challenge the enforceability of any provision of this Agreement, and waives any right it may have under applicable law to revoke this Agreement or any of the provisions of this Agreement. The terms of this Agreement shall survive, and shall continue in full force and effect, in any Insolvency or Liquidation Proceeding. Without limiting the generality of the foregoing, this Agreement, which is intended to constitute and shall be deemed to constitute a “subordination agreement” within the meaning of Section 510(a) of the Bankruptcy Code, shall be effective before, during and after the commencement of an Insolvency or Liquidation Proceeding. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall not invalidate the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. All references to the Parent or any other Grantor shall include the Parent or such Grantor as debtor and debtor-in-possession and any receiver or trustee for the Parent or any other Grantor (as the case may be) in any Insolvency or Liquidation Proceeding. This Agreement shall terminate and be of no further force and effect, (i) with respect to the Second-Lien Agent, the other Second-Lien Claimholders and the Second-Lien Obligations, upon the later of (1) the date upon which the obligations under the Second-Lien Loan Documents terminate if there are no other Second-Lien Obligations outstanding on such date and (2) if there are other Second-Lien Obligations outstanding on such date, the date upon which such Second-Lien Obligations terminate and (ii) with respect to the First-Lien Agents, the other First-Lien Creditors and the First-Lien Obligations, First-Lien Obligations, either (x) the date of the Discharge of First-Lien Obligations, subject to the rights of the First-Lien Creditors under Section 5.6 (including that such date shall be deemed not to have occurred in the event of any contemporaneous or subsequent Refinancing of the First-Lien Obligations) or Section 6.5 of this Agreement and except to the extent any such term or provision, by its terms, survives any Discharge of First-Lien Obligations or (y) the date of conversion of all of the outstanding First-Lien Obligations into common stock of the Parent in accordance with the terms of the First-Lien Purchase Agreement.

8.3 Amendments; Waivers. (a) No amendment, modification or waiver of any of the provisions of this Agreement shall be made unless the same shall be in writing signed on behalf of each party hereto; provided neither the Parent nor any other Grantor shall have any right to

consent to or approve any amendment, modification or waiver of any provision of this Agreement except to the extent their rights are directly affected thereby; provided further that additional Grantors may be added as parties hereto in accordance with the provisions of Section 8.18 of this Agreement.

(b) Each waiver of the terms of this Agreement, if any, shall be a waiver only with respect to the specific instance involved and shall not impair the rights of the parties making such waiver or the obligations of the other parties to such party in any other respect or at any other time. Notwithstanding the foregoing, neither Parent nor any Grantor shall have any right to consent to or approve any amendment, modification or waiver of any provision of this Agreement except to the extent the liabilities, duties or obligations of the Parent or such Grantor are increased, expanded, or made more burdensome to the Parent or such Grantor, as the case may be, as a result of such amendment, modification or waiver.

8.4 Information Concerning Financial Condition of the Parent and its Subsidiaries. The First-Lien Agents and the First-Lien Creditors, on the one hand, and the Second-Lien Agent and the Second-Lien Claimholders, on the other hand, shall each be responsible for keeping themselves informed of (a) the financial condition of the Parent and its Subsidiaries and all endorsers and/or guarantors of the First-Lien Obligations or the Second-Lien Obligations and (b) all other circumstances bearing upon the risk of nonpayment of the First-Lien Obligations or the Second-Lien Obligations. The First-Lien Agents and the other First-Lien Creditors shall have no duty to advise the Second-Lien Agent or any other Second-Lien Claimholder of information known to it or them regarding such condition or any such circumstances or otherwise. In the event the First-Lien Agent or any of the other First-Lien Creditors, in its or their sole discretion, undertakes at any time or from time to time to provide any such information to the Second-Lien Agent or any other Second-Lien Claimholder, it or they shall be under no obligation (w) to make, and the First-Lien Agents and the other First-Lien Creditors shall not make, any express or implied representation or warranty, including with respect to the accuracy, completeness, truthfulness or validity of any such information so provided, (x) to provide any additional information or to provide any such information on any subsequent occasion, (y) to undertake any investigation or (z) to disclose any information which, pursuant to accepted or reasonable commercial finance practices, such party wishes to maintain confidential or is otherwise required to maintain confidential. The Second-Lien Agent and the other Second-Lien Claimholders shall have no duty to advise the First-Lien Agents or any other First-Lien Creditor of information known to it or them regarding such condition or any such circumstances or otherwise.

8.5 Subrogation. Subject to the Discharge of First-Lien Obligations, with respect to the value of any payments or distributions in cash, property or other assets (in each case of Collateral or proceeds thereof) that the Second-Lien Claimholders or Second-Lien Agent pay over to a First-Lien Agent or any of the other First-Lien Creditors under the terms of this Agreement, the Second-Lien Agent and the other Second-Lien Claimholders shall be subrogated to the rights of the First-Lien Agents and such other First-Lien Creditors; provided that, the Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, hereby agrees not to assert or enforce any or all such rights of subrogation it may acquire as a result of any payment hereunder until the Discharge of First-Lien Obligations has occurred.

All payments received by a First-Lien Agent or the other First-Lien Creditors may be applied, reversed and reapplied, in whole or in part, to such part of the First-Lien Obligations as the First-Lien Creditors, in their sole discretion, deem appropriate, subject to the terms of any intercreditor agreement between the First-Lien Agents. The Second-Lien Agent, on behalf of itself and the Second-Lien Claimholders, assents to any extension or postponement of the time of payment of the First-Lien Obligations or any part thereof and to any other indulgence with respect thereto, to any substitution, exchange or, subject to the terms of Section 5.1(a) hereof, release of any security constituting Collateral which may at any time secure any part of the First-Lien Obligations and to the addition of , or the release of in accordance with the terms hereof, any other Person primarily or secondarily liable therefor; provided, that the parties hereto agree that (x) the Parent shall not, and shall not permit any other Grantor to, substitute or exchange any security constituting Collateral under this Section 8.6, unless it has also granted or contemporaneously grants a Lien on such substituted or exchanged asset or property to secure the Second-Lien Obligations and has taken all actions reasonably requested by the Second-Lien Agent to perfect such new Liens, and (y) in furtherance of Section 2.4(ii) hereof, with respect to any Person added or released as a guarantor pursuant to this Section 8.6, the parties will enter into such documentation as is necessary to ensure that the guarantors (and the Collateral pledged by such guarantors) for the First-Lien Obligations and the Second-Lien Obligations shall be identical.

THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS.

WARRANT AGREEMENT

To Purchase Shares of Class A Common Stock of

KIOR, INC.

Dated as of [ ] (the “Effective Date”)

WHEREAS, Kior, Inc., a Delaware corporation (the “Company”), has entered into a Loan and Security Agreement of even date herewith (the “Loan Agreement”) with [ ] (the “Warrantholder”);

WHEREAS, the Company desires to grant to Warrantholder, in consideration for, among other things, the financial accommodations provided for in the Loan Agreement, the right to purchase shares of its Class A Common Stock (as defined below) pursuant to this Warrant Agreement (this “Warrant”);

NOW, THEREFORE, in consideration of Warrantholder executing and delivering the Loan Agreement and providing the financial accommodations contemplated therein, and in consideration of the mutual covenants and agreements contained herein, the Company and Warrantholder agree as follows:

Section 1. Grant of the Right to Purchase Warrant Shares. For value received, the Company hereby grants to Warrantholder, and Warrantholder is entitled, upon the terms and subject to the conditions hereinafter set forth, to subscribe for and purchase, from the Company, [the quotient of (a) [10% of loan amount extended divided by (b) the Exercise Price] fully paid and non-assessable shares of Class A Common Stock at a per share price equal to the Exercise Price (as defined below). The number and Exercise Price of such shares are subject to adjustment as provided in Section 8. As used herein, the following terms shall have the following meanings:

“Act” means the Securities Act of 1933, as amended.

“Affiliate” means, with respect to any person, any other person directly or indirectly controlling, controlled by or under common control with such first person. As used in this definition of the term “Affiliate,” “control” (including the terms “controlled by” and “under common control with”) means the possession, directly or indirectly, of the power to direct or cause the direction of the management policies of a person by reason of ownership of voting securities, by contract or otherwise.

“Board” means the board of directors of the Company.

“Business Day” means any day, except Saturday, Sunday or legal holiday, on which banking institutions in the city of Los Angeles are authorized or obligated by law or executive order to close.

“Bylaws” means the Company’s bylaws or other similar governing provisions, as may be amended from time to time.

“Charter” means the Company’s Certificate of Incorporation or other constitutional document, as may be amended from time to time.

“Class A Common Stock” means shares of the Company’s Class A common stock, $.0001 par value per share.

“Exercise Price” means the closing price of a share of Class A Common Stock on the date of the Loan Agreement, as adjusted as set forth herein.

“Form Warrant” means a warrant in the form set forth in Exhibit E of the Loan Agreement.

“Purchase Price” means, with respect to any exercise of this Warrant, an amount equal to the Exercise Price as of the Exercise Date for such exercise multiplied by the number of Warrant Shares requested to be exercised under this Warrant pursuant to such exercise.

“Warrant Shares” means the shares of Class A Common Stock issuable upon exercise hereof.

Section 2. Term of the Agreement. Except as otherwise provided for herein, the term of this Warrant and the right to purchase Warrant Shares as granted under this Warrant shall commence on the Effective Date and shall be exercisable, in whole or in part, at any time, or from time to time, for a period ending at 5:00 p.m., California time, on the date that is seven (7) years after the Effective Date or, if such day is not a Business Day, on the next preceding Business Day (such date or next preceding Business Day, as applicable, the “Expiration Date”).

Section 3. Exercise of the Purchase Rights.

(a) Exercise. The purchase rights set forth in this Warrant are exercisable by Warrantholder, in whole or in part, at any time, or from time to time, prior to 5:00 p.m., California Time, on the Expiration Date, by tendering to the Company at its principal office a notice of exercise in the form attached hereto as Exhibit I (the “Notice of Exercise”), duly completed and executed. The date on which such Notice of Exercise is so tendered is herein referred to as the “Exercise Date” for such exercise. Promptly upon receipt of the Notice of Exercise and the payment of the Purchase Price in accordance with the terms set forth below, and in no event later than three (3) days thereafter, the Company shall issue to Warrantholder a certificate for the number of Warrant Shares purchased and shall execute the acknowledgment of exercise in the form attached hereto as Exhibit II (the “Acknowledgment of Exercise”) indicating the number of shares which remain subject to future purchases, if any.

The Purchase Price may be paid at Warrantholder’s election either (i) by cash or check, or (ii) by surrender of this Warrant for Warrant Shares to be exercised under this Warrant, after which the Company shall, if the remaining number of shares purchasable hereunder (assuming no Net Issuance) immediately after the relevant exercise, as determined below, is greater than zero, execute and deliver, to Warrantholder, an amended Agreement covering such remaining number of shares (“Net Issuance”). If Warrantholder elects the Net Issuance method, the Company will issue Warrant Shares in accordance with the following formula:

LOGO

Where:

X = the number of Warrant Shares to be issued to Warrantholder.

Y =

the number of Warrant Shares requested to be exercised under this Warrant (including the number of shares to be cancelled in payment of the Purchase Price).

A =

the fair market value of one (1) share of Class A Common Stock on the Exercise Date.

B =

the Exercise Price per share for such Warrant Shares.

For purposes of the above calculation, the fair market value of the Class A Common Stock shall mean with respect to each share of Class A Common Stock:

(i) if the Class A Common Stock is traded on the New York Stock Exchange, the American Stock Exchange, any exchange operated by the NASDAQ Stock Market, LLC or any other securities exchange, the fair market value shall be deemed to be the average of the closing prices per share over the five (5) trading day period ending on, and including, the Exercise Date; or

(ii) if at any time the Class A Common Stock is not listed on any securities exchange, the fair market value shall be the price per share which the Company could obtain from a willing buyer (not a current employee or Affiliate) for Class A Common Stock, in an arms’ length transaction, sold by the Company from authorized but unissued shares, as determined in good faith by the Board.

Upon partial exercise by either cash or Net Issuance, the Company shall promptly issue an amended Agreement representing the remaining number of shares purchasable hereunder (assuming no Net Issuance). All other terms and conditions of such amended Agreement shall be identical to those contained herein, including, but not limited to the Effective Date hereof.

(b) Exercise Prior to Expiration. To the extent this Warrant is not, as of the Expiration Date, previously exercised as to all the Warrant Shares subject hereto, and if the fair market value per share of Class A Common Stock on the Expiration Date is greater than the Exercise Price then in effect, this Warrant shall be deemed automatically exercised, on a Net Issuance basis, pursuant to Section 3(a) (even if not surrendered) on such Expiration Date. For purposes of such automatic exercise, the fair market value per share of Class A Common Stock upon such expiration shall be determined pursuant to Section 3(a). To the extent this Warrant or any portion thereof is deemed automatically exercised pursuant to this Section 3(b), the Company agrees to promptly notify Warrantholder of the number of Warrant Shares, if any, Warrantholder is to receive by reason of such automatic exercise.

(c) Legend. Each certificate for the Warrant Shares purchased upon exercise of this Warrant shall bear the restrictive legend set forth on the first page of this Warrant. Such legend shall be removed and the Company shall, or shall instruct its transfer agent to, issue a certificate without such legend or any other legend to the holder of such shares (i) if such shares are sold or transferred pursuant to an effective registration statement under the Act covering the resale of such shares by the holder thereof, (ii) if such shares are sold or transferred pursuant to Rule 144 under the Act, (iii) if, upon advice of counsel to the Company, such shares are eligible for resale without any restrictions under Rule 144 under the Act, or (iv) upon the request of such holder if such request is accompanied (at such holder’s expense) by either (x) a written opinion of counsel reasonably satisfactory to the Company that registration is not required under the Act or any applicable state securities laws for the resale of the Warrant Shares purchased upon exercise of this Warrant or (y) a certification by such holder, in customary form, that conditions to the resale of such shares pursuant to Rule 144(b) (or any successor thereto) have been satisfied (it being understood that in no event shall such holder be required to certify as to the satisfaction of the conditions set forth in paragraph (c) or (i) of Rule 144 (or any successor thereto). The removal of such restrictive

legend from any certificates representing the Warrant Shares purchased upon exercise of this Warrant is predicated upon the Company’s reliance that the holder of such shares would sell, transfer, assign, pledge, hypothecate or otherwise dispose of such shares pursuant to either the registration requirements of the Act, including any applicable prospectus delivery requirements, or an exemption therefrom, or in a transaction not subject thereto, and that if such shares are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein.

Section 4. Reservation of Shares. During the term of this Warrant, the Company will at all times have authorized and reserved a sufficient number of shares of Class A Common Stock to provide for the exercise of the rights to purchase Warrant Shares as provided for herein, assuming this Warrant were exercised in full and not on a Net Issuance basis.

Section 5. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the fair market value per share of Class A Common Stock on the Exercise Date for such exercise.

Section 6. No Rights as Shareholder/Stockholder. This Agreement does not entitle Warrantholder to any voting rights or other rights as a shareholder/stockholder of the Company prior to the exercise of this Warrant.

Section 7. Warrantholder Registry. The Company shall maintain a registry showing the name and address of the registered holder of this Warrant. Warrantholder’s initial address, for purposes of such registry, is set forth below Warrantholder’s signature on this Warrant. Warrantholder may change such address by giving written notice of such changed address to the Company.

Section 8. Adjustment Rights. The Exercise Price and the number of Warrant Shares purchasable hereunder are subject to adjustment, as follows:

(a) Class A Common Stock Change Event. If at any time there shall occur any transaction (each, a “Class A Common Stock Change Event”) (i) that is either (w) a recapitalization, reclassification or change of the Class A Common Stock (other than changes resulting from a subdivision or combination or changes in par value, including from par value to no par value or from no par value to par value); (x) any consolidation, merger or combination involving the Company; (y) any sale, lease or other transfer to a third party of substantially all of the consolidated assets of the Company and its subsidiaries, taken as a whole; or (z) any statutory share exchange; and (ii) as a result of such transaction, the Class A Common Stock would be converted into, or exchanged for, or would constitute solely the right to receive, stock, other securities or other property or assets (including cash or any combination thereof) (such stock, securities, property, assets or cash, the “Reference Property,” and the amount of Reference Property that a holder of one (1) share of Class A Common Stock would be entitled to receive on account of such transaction (without regard to any arrangement pursuant to which fractional units of property will not be delivered), a “Reference Property Unit”), then the Company or such successor or purchasing person, as the case may be, shall, as a condition precedent to such Class A Common Stock Change Event (and, in the event such successor or purchasing person is not the Company, the Company shall cause such successor or purchasing Person to) execute and deliver to Warrantholder an amended Warrant providing that, from and after the effective time of such Class A Common Stock Change Event, the consideration due upon exercise of this Warrant shall be determined in the same manner as if each reference to any number of shares of Class A Common Stock in this Warrant were instead a reference to the same number of Reference Property Units. For the avoidance of doubt, from and after such effective time, the fair market value of a Reference Property Unit shall be determined (x) to the extent any component thereof consists of securities, on the same basis as that set forth in the penultimate paragraph

of Section 3(a) and (y) to the extent any component thereof does not consist of securities, on the basis of the fair market value thereof (determined in good faith by the Board or the board of directors or similar governing body of the Company’s successor). If a Class A Common Stock Change Event causes the Class A Common Stock to be converted into, or exchanged for, or to constitute solely the right to receive, more than a single type of consideration (determined based in part upon any form of stockholder election), then the amount and kind of Reference Property used to determine the composition of the Reference Property Unit shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Class A Common Stock that affirmatively make such an election. If such successor or purchasing person is not the Company, then such amended Warrant shall provide for the assumption, by such successor or purchasing person, of the Company’s obligations with respect hereto. If, pursuant to such Class A Common Stock Change Event, the Reference Property includes shares of stock or other securities and property of a person other than the successor or purchasing person, as the case may be, in such Class A Common Stock Change Event, then such amended Warrant shall also be executed by such other person. In connection with a Class A Common Stock Change Event, Warrantholder may exercise this Warrant, in whole or in part, with the Exercise Date being deemed to be the effective date of such Class A Common Stock Change Event, without the need for the relevant Notice of Exercise to specify such effective date, provided such Notice of Exercise is tendered to the Company no later than three days before the effective date of such Class A Common Stock Change Event.

(b) Subdivision or Combination of Shares. If the Company at any time shall combine or subdivide the Class A Common Stock, (i) in the case of a subdivision, the Exercise Price shall be proportionately decreased, and the total number of Warrant Shares issuable upon exercise of this Warrant (assuming no Net Issuance) shall be proportionately increased, or (ii) in the case of a combination, the Exercise Price shall be proportionately increased, and the number of Warrant Shares issuable upon the exercise of this Warrant shall be proportionately decreased.

(i) pay a dividend with respect to the Class A Common Stock payable in Class A Common Stock, then (x) the Exercise Price shall be adjusted, from and after the ex date for such dividend or distribution, to that price determined by multiplying the Exercise Price in effect immediately prior to such ex date by a fraction (A) the numerator of which shall be the total number of shares of Class A Common Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Class A Common Stock outstanding immediately after such dividend or distribution; and (y) the total number of Warrant Shares issuable upon exercise of this Warrant (assuming no Net Issuance) shall be adjusted, from and after such ex date, to that number of shares determined by multiplying the total number of Warrant Shares issuable upon exercise of this Warrant (assuming no Net Issuance) immediately prior to such ex date by the reciprocal of the fraction referred to in clause (x) above; or

(ii) make any other distribution with respect to Class A Common Stock, except any distribution specifically provided for in any other clause of this Section 8, then, in each such case, provision shall be made by the Company such that Warrantholder shall receive upon each subsequent exercise of this Warrant, the same kind and amount of property it would have received in such distribution had Warrantholder held, on the record date fixed for the determination of the stockholders of the Company entitled to receive such distribution, a number of shares of Class A Common Stock equal to the number of Warrant Shares issuable upon such exercise.

(d) Notice of Adjustments. If: (i) the Company shall declare any dividend or distribution upon its stock, whether in stock, cash, property or other securities; (ii) the Company shall offer for subscription pro rata to the holders of any class of common stock or other convertible stock any additional shares of stock of any class or other rights; (iii) there shall occur any Class A Common Stock Change Event; (iv) the Company shall sell, lease, license or otherwise transfer all or substantially all of its assets; or (v) there shall be any voluntary dissolution, liquidation or winding up of the Company; then, in connection with each such event, the Company shall send to Warrantholder: (A) at least thirty (30) days’ prior written notice of the date on which the books of the Company shall close or a record shall be taken for such dividend, distribution, subscription rights (specifying the date on which the holders of common stock shall be entitled thereto) or for determining rights to vote in respect of such Class A Common Stock Change Event, dissolution, liquidation or winding up; and (B) in the case of any such Class A Common Stock Change Event, dissolution, liquidation or winding up, at least thirty (30) days’ prior written notice of the date when the same shall take place (and specifying the date on which the holders of common stock shall be entitled to exchange their common stock for securities or other property deliverable upon such Class A Common Stock Change Event, dissolution, liquidation or winding up).

For purposes of this subsection (f), and notwithstanding anything to the contrary in Section 12(f), the notice period shall begin on the date Warrantholder actually receives a written notice containing all the information required to be provided in such subsection (d).

Section 9. Representations, Warranties and Covenants of the Company.

(a) Reservation of Warrant Shares. The Warrant Shares issuable upon exercise of Warrantholder’s rights (assuming no Net Issuance) have been duly and validly reserved and, when issued in accordance with the provisions of this Warrant, will be validly issued, fully paid and non-assessable, and will be free of any taxes, liens, charges or encumbrances of any nature whatsoever; provided, that the Warrant Shares issuable pursuant to this Warrant may be subject to restrictions on transfer under state and/or federal securities laws. The Company has made available to Warrantholder true, correct and complete copies of its Charter and Bylaws. The issuance of certificates for Warrant Shares upon exercise of this Warrant shall be made without charge to Warrantholder for any issuance tax in respect thereof, or other cost incurred by the Company in connection with such exercise and the related issuance of Warrant Shares; provided, that the Company shall not be required to pay any tax which may be payable in respect of any transfer and the issuance and delivery of any certificate in a name other than that of Warrantholder.

(b) Due Authority. The execution and delivery by the Company of this Warrant and the performance of all obligations of the Company hereunder, including the issuance to Warrantholder of the Warrant Shares issuable hereunder, have been duly authorized by all necessary corporate action on the part of the Company. This Agreement: (i) does not violate the Company’s Charter or Bylaws; (ii) does not contravene any law or governmental rule, regulation or order applicable to the Company; and (iii) does not and will not contravene any provision of, or constitute a default under, any indenture, mortgage, contract or other instrument to which the Company is a party or by which it is bound. This Agreement constitutes a legal, valid and binding agreement of the Company, enforceable in accordance with its terms.

(c) Consents and Approvals. No consent or approval of, giving of notice to, registration with, or taking of any other action in respect of any state, federal or other governmental authority or agency is required with respect to the execution, delivery and performance by the Company of its obligations under this Warrant, except for the filing of notices pursuant to Regulation D under the Act and any filing required by applicable state securities law, which filings will be effective by the time required thereby.

(d) Issued Securities. All issued and outstanding Class A Common Stock or other securities of the Company have been duly authorized and validly issued and are fully paid and nonassessable. All outstanding Class A Common Stock or other securities of the Company were issued in full compliance with all federal and state securities laws.

(e) Exempt Transaction. Subject to the accuracy of Warrantholder’s representations in Section 10, the issuance of the Warrant Shares upon exercise of this Warrant will constitute a transaction exempt from (i) the registration requirements of Section 5 of the Act, in reliance upon Section 4(2) thereof, and (ii) the qualification requirements of the applicable state securities laws.

(f) Compliance with Rule 144. If Warrantholder proposes to sell Warrant Shares issuable upon the exercise of this Warrant in compliance with Rule 144 promulgated by the Securities and Exchange Commission (the “SEC”), then, upon Warrantholder’s written request to the Company, the Company shall furnish to Warrantholder, within three Business Days after receipt of such request, a written statement confirming the Company’s compliance with the requirements of paragraphs (c) and (i) of such Rule, as such Rule may be amended from time to time. Until such time as this Warrant and the Warrant Shares issued hereunder have been sold pursuant to an effective registration statement under the Act or such time as the requirements of paragraph (c) of Rule 144, as such Rule may be amended from time to time, no longer apply to this Warrant or to such shares, the Company covenants to timely file all reports required to be filed by the Company under the Securities Exchange Act of 1934, as amended (the “1934 Act”), in such a manner so as to comply with paragraph (c) of Rule 144, as such Rule may be amended from time to time.

(g) Denomination Exchanges. Warrantholder shall have the right to request the Company to cause any portion of this Warrant to be represented by one or more separate warrants (each, a “Separate Warrant”), each in the form of a Form Warrant, and the Company hereby covenants that, upon each such request, the Company shall (x) execute and deliver, to Warrantholder, an amended Warrant, which shall reflect the removal of such portion of such portion of this Warrant; and (y) execute and deliver, to Warrantholder, one or more Separate Warrants, each in the form of the Form Warrant, having an aggregate number of underlying Warrant Shares (assuming no Net Issuance), and having a per share Exercise Price, equal to the number of underlying Warrant Shares (assuming no Net Issuance) and the Exercise price, respectively, of such portion of this Warrant.

Section 10. Representations and Covenants of Warrantholder. This Agreement has been entered into by the Company in reliance upon the following representations and covenants of Warrantholder:

(a) Investment Purpose. The right to acquire Warrant Shares upon exercise of Warrantholder’s rights contained herein will be acquired for investment and not with a view to the sale or distribution of any part thereof, and Warrantholder has no present intention of selling or engaging in any public distribution of the same, in each case except pursuant to a registration or exemption.

(b) Private Issue. Warrantholder understands (i) that the Warrant Shares issuable upon exercise of this Warrant is not registered under the Act or qualified under applicable state securities laws on the ground that the issuance contemplated by this Warrant will be exempt from the registration and qualifications requirements thereof, and (ii) that the Company’s reliance on such exemption is predicated in part on the representations set forth in this Section 10.

(c) Financial Risk. Warrantholder has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its investment, and has the ability to bear the economic risks of its investment.

(d) Risk of No Registration. Warrantholder understands that if the Company does not have any class of its securities registered pursuant to Section 12 of the 1934 Act, or file reports pursuant to Section 15(d) of the 1934 Act, or if a registration statement covering this Warrant or the underlying Warrant Shares under the Act is not in effect when it desires to sell (i) the rights to purchase Warrant Shares pursuant to this Warrant or (ii) the Warrant Shares issuable upon exercise of the right to purchase, it may be required to hold such securities for an indefinite period. Warrantholder also understands that any sale of (A) its rights hereunder to purchase Warrant Shares or (B) Warrant Shares issued or issuable hereunder which might be made by it in reliance upon Rule 144 under the Act may be made only in accordance with the terms and conditions of that Rule.

(e) Accredited Investor. Warrantholder is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Act.

(f) No Short Sales. Prior to the Effective Date, Warrantholder has not engaged in any “short sales” of the Class A Common Stock, which short sales have not been covered before such Effective Date. At no time when Warrantholder holds (or has a beneficial interest in) any Warrant Shares issued or issuable pursuant to this Warrant shall Warrantholder engage in “short sales” of the Class A Common Stock. The term “short sale” shall mean any sale of a security which the seller does not own or any sale which is consummated by the delivery of a security borrowed by, or for the account of, the seller.

Section 11. Transfers. Subject to compliance with applicable federal and state securities laws, this Warrant and all rights hereunder are transferable, in whole or in part, without charge to the holder hereof (except for transfer taxes) upon surrender of this Warrant properly endorsed. Each taker and holder of this Warrant, by taking or holding the same, consents and agrees that this Warrant, when endorsed in blank, shall be deemed negotiable, and that the holder hereof, when this Warrant shall have been so endorsed and its transfer recorded on the Company’s books, shall be treated by the Company and all other persons dealing with this Warrant as the absolute owner hereof for any purpose and as the person entitled to exercise the rights represented by this Warrant. The transfer of this Warrant shall be recorded on the books of the Company upon receipt by the Company of a notice of transfer in the form attached hereto as Exhibit III (the “Transfer Notice”), at its principal offices and the payment to the Company of all transfer taxes and other governmental charges imposed on such transfer, in each case that are not to be paid by the Company pursuant hereto. Until the Company receives such Transfer Notice, the Company may treat the registered owner hereof as the owner for all purposes.

Section 12. Miscellaneous.

(a) Effective Date. The provisions of this Warrant shall be construed and shall be given effect in all respects as if it had been executed and delivered by the Company on the date hereof. This Agreement shall be binding upon any successors or assigns of the Company.

(b) Remedies. In the event of any default hereunder, the non-defaulting party may proceed to protect and enforce its rights either by suit in equity and/or by action at law, including but not limited to an action for damages as a result of any such default, and/or an action for specific performance for any default where the non-defaulting party will not have an adequate remedy at law and where damages will not be readily ascertainable. Each party hereto expressly agrees that it shall not oppose an application by the non-defaulting party or any other person entitled to the benefit of this Warrant requiring specific performance of any or all provisions hereof or enjoining a party from continuing to commit any such breach of this Warrant. The parties hereto hereby agree that the terms of this Warrant shall be specifically enforceable by either party hereto.

(c) No Impairment of Rights. The Company will not, by amendment of its Charter or through any other means, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in order to protect the rights of Warrantholder against impairment.

(d) Attorney’s Fees. In any litigation, arbitration or court proceeding between the Company and Warrantholder relating hereto, the prevailing party shall be entitled to reasonable and documented attorneys’ fees and expenses and all costs of proceedings incurred in enforcing this Warrant. For the purposes of this Section 12(d), attorneys’ fees shall include without limitation fees incurred in connection with the following: (i) contempt proceedings; (ii) discovery; (iii) any motion, proceeding or other activity of any kind in connection with an insolvency proceeding; (iv) garnishment, levy, and debtor and third party examinations; and (v) post-judgment motions and proceedings of any kind, including without limitation any activity taken to collect or enforce any judgment.

(e) Severability. In the event any one or more of the provisions of this Warrant shall for any reason be held invalid, illegal or unenforceable, the remaining provisions of this Warrant shall be unimpaired, and the invalid, illegal or unenforceable provision shall be replaced by a mutually acceptable valid, legal and enforceable provision, which comes closest to the intention of the parties underlying the invalid, illegal or unenforceable provision.

(f) Notices. Except as otherwise provided herein, any notice, demand, request, consent, approval, declaration, service of process or other communication that is required, contemplated, or permitted under this Warrant or with respect to the subject matter hereof shall be in writing, and shall be deemed to have been validly served, given, delivered, and received upon the earlier of: (i) the day of transmission by facsimile or hand delivery if transmission or delivery occurs on a Business Day at or before 5:00 pm in the time zone of the recipient, or, if transmission or delivery occurs on a non-Business Day or after such time, the first Business Day thereafter, or the first Business Day after deposit with an overnight express service or overnight mail delivery service; or (ii) the third calendar day after deposit in the United States mails, with proper first class postage prepaid, and shall be addressed to the party to be notified as follows:

Attention: Chris Artzer

or to such other address as each party may designate for itself by like notice.

(g) Entire Agreement; Amendments. This Agreement and the Loan Agreement constitute the entire agreement and understanding of the parties hereto in respect of the subject matter hereof, and supersedes and replaces in their entirety any prior proposals, term sheets, letters, negotiations or other documents or agreements, whether written or oral, with respect to the subject matter hereof. None of the terms of this Warrant may be amended except by an instrument executed by each of the parties hereto.

(h) Headings. The various headings in this Warrant are inserted for convenience only and shall not affect the meaning or interpretation of this Warrant or any provisions hereof.

(i) No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Warrant. In the event an ambiguity or question of intent or interpretation arises, this Warrant shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Warrant.

(j) No Waiver. No omission or delay by either party at any time to enforce any right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by the other party at any time designated, shall be a waiver of any such right or remedy to which such party is entitled, nor shall it in any way affect the right of such party to enforce such provisions thereafter.

(k) Survival. All agreements, representations and warranties contained in this Warrant or in any document delivered pursuant hereto shall be for the benefit of Warrantholder and shall survive the execution and delivery of this Warrant and the expiration or other termination of this Warrant.

(l) Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of New York, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction.

(m) Consent to Jurisdiction and Venue. All judicial proceedings arising in or under or related to this Warrant may be brought in any state or federal court of competent jurisdiction located in the State of California. By execution and delivery of this Warrant, each party hereto generally and unconditionally: (a) consents to personal jurisdiction in New York, New York; (b) waives any objection as to jurisdiction or venue in New York, New York; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d) irrevocably agrees to be bound by any judgment rendered thereby in connection with this Warrant. Service of process on any party hereto in any action arising out of or relating to this Warrant shall be effective if given in accordance with the requirements for notice set forth in Section 12(f), and shall be deemed effective and received as set forth in Section 12(f). Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either party to bring proceedings in the courts of any other jurisdiction.

(n) Mutual Waiver of Jury Trial. Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF THE COMPANY AND WARRANTHOLDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY THE COMPANY AGAINST WARRANTHOLDER OR ITS ASSIGNEE OR BY WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY. This waiver extends to all such Claims, including Claims that involve persons other than the Company and Warrantholder; Claims that arise out of or are in any way connected to the relationship between the Company and Warrantholder; and any Claims for damages, breach of contract, specific performance, or any equitable or legal relief of any kind, arising out of this Warrant.

(o) Arbitration. If the Mutual Waiver of Jury Trial set forth in Section 12(n) is ineffective or unenforceable, the parties agree that all Claims shall be submitted to binding arbitration in accordance with the commercial arbitration rules of JAMS (the “Rules”), such arbitration to occur before one arbitrator, which arbitrator shall be a retired New York state judge or a retired Federal court judge. Such proceeding shall be conducted in New York, New York, with New York rules of evidence and discovery applicable to such arbitration. The decision of the arbitrator shall be binding on the parties, and shall be final and nonappealable to the maximum extent permitted by law. Any judgment rendered by the arbitrator may be entered in a court of competent jurisdiction and enforced by the prevailing party as a final judgment of such court.

(p) Prearbitration Relief. In the event Claims are to be resolved by arbitration, either party may seek from a court of competent jurisdiction identified in Section 12(m), any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution by binding arbitration.

(q) Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same instrument.

(r) Specific Performance. The parties hereto hereby declare that it is impossible to measure in money the damages which will accrue to a party hereto by reason of the other party’s failure to perform any of the obligations under this Warrant and agree that the terms of this Warrant shall be specifically enforceable by either party hereto. If a party hereto institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom such action or proceeding is brought hereby waives the claim or defense therein that such party has an adequate remedy at law, and such person shall not offer in any such action or proceeding the claim or defense that such remedy at law exists.

Berry v. KiOR, Inc., et a/4: 13-cv-02443 (S.D. Tex.)

The Company and certain of its officers have been named in a purported class action lawsuit pending in the United States District Court for the Southern District of Texas, brought by Michael Berry on behalf of individuals who purchased the Company’s common stock. The initial complaint alleged that the Company and its officers made false or misleading statements concerning projected biofuel production levels at the Company’s Columbus, Mississippi facility. The complaint advanced claims pursuant to Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 promulgated thereunder, and sought unspecified compensatory damages and costs and expenses, including attorneys’ fees.

On October 21,2013, two other purported purchasers of the Company’s common stock, Sharon Kegerries and Dave Carlton, filed motions to be appointed as lead plaintiffs in the class action and to have their attorneys approved as lead counsel. Mr. Berry did not file a motion to be appointed as lead plaintiff. On November 25, 2013, Sharon Kegerries and Dave Carlton were appointed Lead Plaintiffs and their selection of co-lead counsel was approved by the court. Lead Plaintiffs then filed an amended class action complaint on January 27, 2014, alleging the Exchange Act and Rule 10b-5 violations of the original complaint and seeking to represent a class of purchasers of Company stock from August 14, 2012 to January 8, 2014. The amended class action complaint names the Company, Fred Cannon and John Karnes as defendants, seeks unspecified compensatory damages and costs and expenses, including attorneys’ fees.

Gedig v. Cannon, et al 4: 13-cv-03773 (S.D. Tex.)

The Company, its President and former Chief Executive Officer and one of its outside directors have been named in a lawsuit pending in the United States District Court for the Southern District of Texas, brought on a derivative basis, allegedly on behalf of the Company. The complaint was filed on December 12,2013, and names as defendants Fred Cannon, John Karnes, Samir Kaul, David Paterson, William Roach, and Gary Whitlock, and names the Company as a nominal defendant. The complaint was filed under seal and alleges breaches of the fiduciary duties of loyalty and good faith in connection with allegedly false or misleading statements about the progress at the Company’s Columbus, Mississippi facility and the timing of projected biofuel production levels.

SEC Investigation

The Company has received a subpoena issued pursuant to a formal order of investigation by the United States Securities and Exchange Commission, dated January 28, 2014. The subpoena seeks documents about, among other subject matters, the progress at its Columbus, Mississippi facility and the timing of projected biofuel production levels. The Company’s document production in response to the subpoena is ongoing.

Department of Labor Whistleblower Matter

A complaint has been field against the Company by Mark Ross, an ex-employee of the Company, with the US Department of Labor Occupational Safety and Health Administration, alleging retaliation in violation of the Sarbanes-Oxley Act.
