The parties hereby agree as follows:

ARTICLE 1

AUTHORIZATION AND SALE OF SECURITIES

1.1 Authorization and Sale of Securities.

(A) Subject to the terms and conditions of this Agreement, each Purchaser agrees to purchase, severally and not jointly, and KiOR agrees to sell and issue to each Purchaser, one or more Notes, in the principal amount set forth opposite such Purchaser’s name under the heading “First Closing” on Exhibit A attached to this Agreement. The initial purchase and sale of the Notes shall take place remotely via the exchange of documents and signatures immediately following the execution and delivery of this Agreement, subject to the satisfaction of each of the Closing Conditions set forth in Section 3.1(A) below (which time and place are designated as the “First Closing”). At the First Closing, KiOR shall deliver to each Purchaser an executed Note being purchased by such Purchaser against payment of the purchase price therefor by check payable to KiOR, by wire transfer to the bank account that has been designated by KiOR, and/or, to the extent contemplated by the terms of the Existing Loan as in effect on the date hereof, by cancellation or conversion of indebtedness of KiOR to KFT Trust.

(B) Subject to the terms and conditions of this Agreement and to the right of each Purchaser to exercise its Option Right set forth in Section 1.1(D) below (which right, if exercised in full, shall terminate such Purchaser’s rights and obligations in respect of a Second Closing or Call Closing as applicable), in the event that KiOR consummates a Financing Event, then each Purchaser shall purchase, severally and not jointly, and KiOR shall sell, pursuant to the terms and conditions of this Agreement, the Shares at the Share Price, in the amounts set forth opposite such Purchaser’s name under the heading “Second Closing” on Exhibit A attached to this Agreement. Subject to the satisfaction in full of each of the Closing Conditions set forth in Section 3.1(B) and to the execution and delivery of those instruments, certificates and agreements contemplated by this Agreement to be delivered at or prior the purchase and sale of such Shares, the purchase and sale of such Shares shall take place on the date and at substantially the same time that KiOR consummates the Financing Event contemplated by this Section 1.1(B) (such purchase and sale, the “Second Closing”). At the Second Closing, KiOR shall deliver to each Purchaser one or more certificates evidencing the Shares being purchased by such Purchaser against payment of the purchase price therefor by check payable to KiOR, by wire transfer to the bank account designated by KiOR in the notice referred to in the immediately preceding sentence and/or, to the extent contemplated by the terms of the Existing Loan as in effect on the date hereof, by cancellation or conversion of indebtedness of KiOR to the applicable Purchaser.

(C) Subject to the terms and conditions of this Agreement and to the right of each Purchaser to exercise its Option Right set forth in Section 1.1(D) below (which right, if exercised in full, shall terminate such Purchaser’s rights and obligations in respect of a Second Closing or Call Closing, as applicable), in the event that KiOR consummates a Financing Event, then each Purchaser (other than ▇▇▇▇▇▇ Ventures III, LP to which this Section 1.1(C) shall not apply) shall purchase, severally and not jointly, and KiOR shall sell, pursuant to the terms and conditions of this Agreement, solely upon the election of KiOR (the “Call Right”), at any time beginning three hundred sixty five (365) days following the consummation of the Financing Event (the “Call Date”), by delivering notice of such election to the Purchasers pursuant to Section 10.2 hereof, the Shares (subject to adjustment as set forth below) at the Share Price, in the amounts set forth opposite each Purchaser’s name under the heading “Call Closing” on Exhibit A attached to this Agreement. Subject to the satisfaction in full of each of the Closing Conditions set forth in Section 3.1(C) and to the execution and delivery of those instruments, certificates and agreements contemplated by this Agreement to be delivered at or prior the purchase and sale of such Shares, the purchase and sale of such Shares shall take place on the date set forth in the election notice described herein (which shall not be less than five 5 days after the Call Right is executed) (such purchase and sale, a “Call Closing”). At the Call Closing, KiOR shall deliver to each Purchaser one or more certificates evidencing the Shares being purchased by such Purchaser against payment of the purchase price therefor by check payable to KiOR or by wire transfer to the bank account designated by KiOR in the notice referred to in the immediately preceding sentence. Notwithstanding the foregoing or anything else herein to the contrary, KiOR’s right to exercise the Call Right shall terminate, if not terminated sooner pursuant to the terms hereof, on the two year anniversary of the consummation of the Financing Event (the “Two Year Date”). Except with respect to ▇▇▇▇▇▇ Ventures III, LP, to which the Call Right shall not apply, in the event that KiOR shall have consummated, between the date of the First Closing and the date that the Call Right is exercised, a sale or sales of its equity securities (the “Equity Financing Transactions”) resulting in aggregate proceeds to KiOR of at least $100,000,000, the Call Right shall terminate. If KiOR consummates Equity Financing Transactions that result in aggregate gross proceeds to KiOR of less than $100,000,000 prior to the date on which the Call Right is exercised, then the amount of Shares required to be purchased by the Purchasers at the Call Closing shall be reduced by an amount equal to $100,000,000 less the amount of cash proceeds received by KiOR in such Equity Financing Transactions; provided, however; that in no event shall the aggregate proceeds to be paid by the Purchasers at such Call Closing exceed $35,000,000. For purposes of the foregoing calculations of proceeds: (i) the sale of the principal amount of the Notes and Shares pursuant to this Agreement, other than the sales to KFT Trust, shall be included in such calculations and (ii) the sale of shares of Class A Common Stock pursuant to that certain Class A Common Stock Purchase Agreement by and between Kior and the purchaser set forth therein and dated on or about the date hereof, shall be included in such calculations.

(D) Notwithstanding Section 1.1(B), or Section 1.1(C) at any time prior to the earlier to occur of (i) the Two Year Date and (ii) the Maturity Date, so long as a Purchaser beneficially owns at least twenty percent (20%) of the shares of Class A Common Stock issued or issuable upon conversion of the Notes purchased by such Purchaser, and subject to compliance with applicable securities laws, such Purchaser may exercise its Option Right, by delivering at least three (3) days written notice to KiOR, and may purchase the Shares at the Share Price, in the amounts set forth opposite each Purchaser’s name under the heading “Second Closing” on Exhibit A attached to this Agreement and under the heading “Call Closing” on Exhibit A (in each case to the extent not previously purchased by such Purchaser or its assignee).

1.2 Use of Proceeds. In accordance with the directions of the Board of Directors, the Company will use the proceeds from the sale of the Securities for the construction of the Facility and for general corporate purposes.

1.3 Tax Status of Purchasers. Each Purchaser, if reasonably requested by the Company, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Company to determine whether or not such Purchaser is subject to withholding or information reporting requirements.

4.2 Collateral. The Company owns the Collateral, free of all Liens, except for Permitted Liens and Permitted Transfers. The Company has the corporate or limited liability company power and authority to grant to Agent a Lien in the Collateral as security for the Secured Obligations. This Agreement is effective to create, as collateral security for the Secured Obligations of such Company, valid and enforceable liens on such Company’s Collateral in favor of the Agent for the benefit of the Purchasers, except as enforceability may be affected by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally. All Liens of Agent in the Collateral are duly perfected, first priority Liens, subject only to Permitted Liens that are expressly allowed to have priority over Agent’s Liens.

4.3 Consents. The Company’s execution, delivery and performance of the Notes, this Agreement and all other Transaction Documents and the transactions contemplated hereby and thereby (including the issuance of any shares of common stock upon conversion of the Notes and upon the Second Closing), (i) have been duly authorized by all necessary corporate or limited liability company action of the Company, (ii) will not result in the creation or imposition of any Lien upon the Collateral, other than Permitted Liens and the Liens created by this Agreement and the other Transaction Documents,

4.5 Reserved.

4.6 Laws. The Company is not in violation of any law, rule or regulation, or in default with respect to any judgment, writ, injunction or decree of any governmental authority, where such violation or default is reasonably expected to be materially adverse to the Company taken as a whole. The Company is not in default in any manner under any provision of any agreement or instrument evidencing Indebtedness, or any other material agreement to which it is a party or by which it is bound, in each case, where such default is reasonably expected to be materially adverse to the Company taken as a whole.

4.7 Information Correct and Current. No financial statement, exhibit or schedule furnished, by or on behalf of the Company to Agent or any Purchaser in connection with any Transaction Document contained any material misstatement of fact or omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were or are made, not misleading in any material respect at the time such statement was made or deemed made. Additionally, any and all financial or business projections provided by the Company to Agent and each Purchaser shall be at the time delivered provided in good faith and based on the most current data and information available to the Company, it being recognized by Agent and each Purchaser that such financial information as it relates to future events is not to be viewed as fact and that actual results during the period or periods covered by such financial information may differ from the projected results set forth therein by a material amount. For purposes of clarification this representation is not intended to apply to nor does it apply to any of the financial statements, exhibits or materials described in Section 4.19 hereof.

4.8 Tax Matters. Except as described on Schedule 4.8, (a) the Company and its Subsidiaries has filed all federal and material state and local Tax returns that it is required to file (or extensions thereof) within the time and manner required by applicable law, (b) the Company and its Subsidiaries has duly paid or fully reserved for all material Taxes or installments thereof (including any interest or penalties) as and when due, which have or may become due pursuant to such returns, and (c) the Company and its Subsidiaries has paid or fully reserved for any material Tax assessment received by the Company or any of its Subsidiaries, if any (including any Taxes being contested in good faith and by appropriate proceedings).

As of the First Closing, except as described on Schedule 4.9, (i) each of the material Copyrights, Trademarks and Patents is valid and enforceable, (ii) no Intellectual Property of the Company has been judged invalid or unenforceable, in whole or in part, by a final, non-appealable decision of a court of competent jurisdiction, and (iii) no claim has been made in writing to the Company that any Intellectual Property violates the rights of any third party, except for any such claims which are not reasonably likely to be found valid or any such claims which, if found valid, would not reasonably be

- 25 -

expected to be materially adverse to the Company taken as a whole. The Company is not in material breach of, nor has the Company failed to perform any material obligations under, any of the foregoing contracts, licenses or agreements and, to the Company’s knowledge, no third party to any such contract, license or agreement is in material breach thereof or has failed to perform any material obligations thereunder, in each case, where such breach or failure would reasonably be expected to be materially adverse to the Company taken as a whole.

4.10 Intellectual Property. Except as described on Schedule 4.10, the Company has all material rights with respect to Intellectual Property necessary in the operation or conduct of the Company’s business as currently conducted and currently contemplated to be conducted. Except as would not reasonably be expected to be materially adverse to the Company taken as whole, the Company owns or has the right to use, pursuant to valid licenses, all software development tools, library functions, compilers and all other third-party software and other items that are used in the design, development, promotion, sale, license, manufacture, import, export, use or distribution of Company Products.

4.11 Company Products. Except as described on Schedule 4.11, no Intellectual Property owned by the Company or Company Product has been or is subject to any actual or, to the knowledge of the Company, threatened (in writing) litigation, proceeding (including any proceeding in the United States Patent and Trademark Office or any corresponding foreign office or agency) or outstanding decree, order, judgment, settlement agreement or stipulation that restricts in any manner the Company’s use, transfer or licensing thereof or that affects the validity, use or enforceability thereof, except in each case, as would not reasonably be expected to be materially adverse to the Company taken as a whole. There is no decree, order, judgment, agreement, stipulation, arbitral award or other provision entered into in connection with any litigation or proceeding against the Company that obligates the Company to grant licenses or ownership interest in any future Intellectual Property related to the operation or conduct of the business of the Company or Company Products, except in each case, as would not reasonably be expected to be materially adverse to the Company taken as a whole. The Company has not received any written notice or claim challenging or questioning the Company’s ownership in any Intellectual Property (or written notice of any claim challenging or questioning the ownership in any licensed Intellectual Property of the owner thereof) or suggesting that any third party has any claim of legal or beneficial ownership with respect thereto, except in each case, as would not reasonably be expected to be materially adverse to the Company taken as a whole. Neither the Company’s use of Intellectual Property nor the production and sale of Company Products infringes the Intellectual Property or other rights of others, provided that such representation is made to the Company’s knowledge with respect to patent rights of others.

4.12 Collateral Information Certificate. The Collateral Information Certificate delivered to the Purchasers by the Company on the date of the First Closing (the “Collateral Information Certificate”) is true and correct in all material respects as of the date of the First Closing.

The Company shall from time to time procure any instruments or documents as may be reasonably requested by Agent or any Purchaser, and take all further action that may be necessary to perfect and protect the Liens granted hereby and thereby. In addition, and for such purposes only, the Company hereby authorizes Agent to execute and deliver on behalf of the Company and to file financing statements without the signature of the Company either in Agent’s name or in the name of Agent as agent and attorney-in-fact for the Company.

(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).

(A) (i) repurchase or redeem any class of stock or other equity interest other than pursuant to (x) employee repurchase plans or similar agreements, or (y) director or consultant repurchase plans or other similar agreements in effect on the date hereof, or (ii) declare or pay any cash dividend or make a cash distribution on any class of stock or other equity interest (except a dividend or distribution may be made by the Company to any Subsidiary, or by any Subsidiary to the Company provided that such Subsidiary is either a Company or will become a Company under the terms and within the time frame set forth in Section 6.8);

- 34 -

The Company must maintain a minimum of $2,000,000 of commercial general liability insurance (including umbrella) for each occurrence. The Company has and agrees to maintain a minimum of $2,000,000 of directors’ and officers’ insurance for each occurrence and $5,000,000 in the aggregate.

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.

6.20 Right of First Offer.

(A) Subject to the terms and conditions of this Section 6.20 and applicable securities laws, if KiOR proposes to offer or sell any New Securities, the Company shall first offer such New Securities to each Purchaser who beneficially owns ten percent (10%) or more of the Shares issued to such Purchaser as of the time of such offer or sale. A Purchaser shall be entitled to apportion the right of first offer hereby granted to it in such proportions as it deems appropriate, among (i) itself, (ii) its affiliates and (iii) its beneficial interest holders, such as limited partners, members or any other Person having “beneficial ownership,” as such term is defined in Rule 13d-3 promulgated under the Exchange Act, of such Purchaser.

i. KiOR shall give notice (the “Offer Notice”) to each such Purchaser, stating (1) its bona fide intention to offer such New Securities, (2) the number of such New Securities to be offered, and (3) the price and terms, if any, upon which it proposes to offer such New Securities.

ii. By notification to KiOR within (I) two (2) days in the case of any New Securities comprised of equity securities, and (II) five (5) days in the case of any New Securities comprised of debt securities, after the Offer Notice is given, each Purchaser may elect to purchase or otherwise acquire, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals such Purchaser’s Pro Rata portion of such New Securities.

iii. Each Purchaser exercising its right of first offer under this Section 6.20 to purchase its Pro Rata portion of the New Securities in full (an “Exercising Purchaser”) will have a right of over-allotment such that if any other Purchaser fails to exercise its right of first offer under this Section 6.20 to purchase its Pro Rata portion of New Securities in full (a “Non-Purchasing Holder”), such Exercising Stockholder may purchase its Pro Rata portion of such unsold securities by giving written notice to the Company within two (2) days from the date that the Company provides written notice of the amount of New Securities as to which such Non-Purchasing Holders have failed to exercise their purchase rights hereunder.

iv. If any Purchaser fails to exercise fully the rights set forth in Section 6.20 within the periods described in clause iii above, the Company will be free to complete the proposed issuance or sale of the New Securities described in the Offer Notice with respect to which Exercising Purchasers failed to exercise the option set forth in this Section 6.20 on terms no less favorable to the Company than those set forth in the Offer Notice (except that the amount of securities to be issued or sold by the Company may be reduced); provided that (x) such issuance or sale is closed within one hundred twenty (120) days after the expiration of the applicable period in clauses ii and iii above and (y) the price at which the New Securities are issued or sold must be equal to or higher than the purchase price described in the Offer Notice. Such periods within which such issuance or sale must be closed will be

- 38 -

extended to the extent necessary to obtain required approvals of Governmental Authorities and other required approvals and the Company will use its commercially reasonable efforts to obtain such approvals. In the event that the Company has not sold such New Securities within such one hundred twenty (120) day period, the Company will not thereafter issue or sell any New Securities, without first again offering such securities to the Purchasers in the manner provided in this Section 6.20.

6.21 [Reserved].

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). The shares of Class A Common Stock issued upon conversion of the Notes shall not be sold, transferred assigned or hypothecated by the Purchasers prior to the six (6) month anniversary of the First Closing; provided that transfer of such shares in connection with a Change in Control or by a Purchaser that is a partnership, a limited liability company or a corporation to (i) a partner of such partnership, a member of such limited liability company or a stockholder of such corporation, (ii) an entity that controls, or is controlled by, or is under common control with such partnership, limited liability company or corporation, or (iii) the estate of any such partner, member or stockholder (collectively, clauses (i) through (iii) the “Permitted Transferees”) during such six (6) month period shall be permitted; provided, further, that in each of the foregoing cases (other than a Change of Control) the proposed transferee of the Notes or the shares of Class A Common Stock issued upon conversion of the Notes held by the Purchaser agrees in writing to take and hold such shares subject to the provisions and upon the conditions specified in this Article 7. 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 Securities shall not be sold, transferred, assigned or hypothecated unless (i) there is an effective registration statement under the Securities Act covering such Securities, (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 Securities 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 Securities that were initially sold by KiOR in reliance on Regulation S, hedging transactions involving such Securities 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 Securities by a Purchaser to a Permitted Transferee; provided, that the proposed transferee of the Securities held by the Purchaser agrees in writing to take and hold such Securities 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.

- 39 -

(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 Securities not made in compliance with this Section 7.1).

7.2 ▇▇▇▇▇▇ Ventures III, LP, VNK Management LLC and KFT Trust Restriction. Each of ▇▇▇▇▇▇ Ventures III, LP, VNK Management LLC and KFT Trust agrees, for the benefit of all the Purchasers, that neither it, nor any of its Affiliates, shall sell, transfer, assign or hypothecate any equity or debt securities of KiOR to any non-Affiliate during periods set forth in the first two sentences of Section 7.1 hereof.

7.3 Restrictive Legends. Each certificate representing the Securities, and any other securities issued in respect of the Securities upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event (except as otherwise permitted by the provisions of this Article 7), shall be stamped or otherwise imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR IN ANY OTHER JURISDICTION.

U.S. Investors: THE SECURITIES REPRESENTED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE SECURITIES LAWS UNLESS OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS.

Non-U.S. Investors: THE SECURITIES REPRESENTED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, AND IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE SECURITIES LAWS UNLESS OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS. HEDGING TRANSACTIONS INVOLVING THE SECURITIES REPRESENTED HEREBY MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE SECURITIES ACT.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.”

7.4 Removal of Legend and Transfer Restrictions. The first paragraph of the foregoing legend shall be removed from the certificates representing any Securities, at the request of the holder thereof, (i) while a registration statement covering the resale of such Securities is effective under the Securities Act of 1933, as amended, (ii) following any sale of such Securities pursuant to Rule 144

- 40 -

(assuming the transferor is not an Affiliate of the Company), (iii) if such Securities are eligible to be sold, assigned or transferred under Rule 144, (iv) in connection with a sale, assignment or other transfer (other than under Rule 144), provided that the Person acquiring such Securities provides KiOR with an opinion of counsel to such Person, in a generally acceptable form, to the effect that such sale, assignment or transfer of the Securities may be made without registration under the applicable requirements of the Securities Act of 1933, as amended or (v) if such legend is not required under applicable requirements of the Securities Act of 1933, as amended (including, without limitation, controlling judicial interpretations and pronouncements issued by the SEC). If a legend is not required pursuant to the foregoing, KiOR shall no later than three (3) Business Days following the delivery by a Purchaser to KiOR or the transfer agent (with notice to KiOR) of a legended certificate representing such Securities (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer, if applicable), together with any other deliveries from such Purchaser as may be required above in this Section 7.4, as directed by such Purchaser, issue and deliver (via reputable overnight courier) to such Purchaser, a certificate representing such Securities that is free from all restrictive and other legends, registered in the name of such Purchaser or its designee. KiOR shall be responsible for any fees with respect to any issuance of Securities or the removal of any legends with respect to any Securities in accordance herewith.

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

- 42 -

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.

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 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.

- 43 -

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.

No amendment, waiver or other modification of any provision of this Agreement or any other Transaction Document, and no consent with respect to any departure by the Company therefrom, shall be effective unless the same shall be in writing and signed by the Required Purchasers (or by Agent at the written request of the Required Purchasers) and the Company that are party thereto and then any such waiver or consent shall be effective, but only in the specific instance and for the specific purpose for which given. In addition to the forgoing, no amendment, waiver, modification, elimination, or consent shall amend, modify, or waive any provision of any Transaction Document that relates to the rights, duties or discretion of Agent, without the written consent of Agent, the Company and the Required Purchasers.

10.4 No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement.

10.5 No Waiver. The powers conferred upon Agent and each Purchaser by this Agreement are solely to protect its rights hereunder and under the other Transaction Documents and its interest in the Collateral and shall not impose any duty upon Agent or any Purchaser to exercise any such powers. No omission or delay by Agent or any Purchaser 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 Company at any time designated, shall be a waiver of any such right or remedy to which Agent or any Purchaser is entitled, nor shall it in any way affect the right of Agent or any Purchaser to enforce such provisions thereafter

- 45 -

10.6 Severability. In case any provision contained in this Agreement should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby.

10.9 [Reserved].

10.10 Assignment. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the parties hereto and their respective permitted successors, assigns, heirs, executors and administrators. This Agreement and the rights of a Purchaser hereunder may not be assigned by the Purchaser without the prior written consent of KiOR, except such consent shall not be required in cases of assignments by a Purchaser as permitted under Section 7.1, provided that such assignee agrees in writing to be bound by the terms of this Agreement and shall be deemed to have made each of the representations and warranties of the Purchasers herein and in the Transaction Documents; provided further that in the event that only a portion of the Note or shares of common stock of such Purchaser are transferred, only the Purchaser or with the election of such Purchaser, only one Permitted Transferee designated by such Purchaser shall have the right to exercise rights hereunder on behalf of all holders of such Purchaser’s Note or shares of common stock. Notwithstanding the foregoing, and with respect to the exercise of the Call Right only, any Purchaser subject to the Call Right may assign the obligation to consummate any Call Closing to any Affiliate of such Purchaser or other third party, provided that such Purchaser shall guaranty and remain liable for the payment of any proceeds at such Call Closing by such assignee.

10.11 Further Assurances.

ARTICLE 11

AGENT

11.1 Appointment and Authority. Each Purchaser appoints and designates KV III 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

- 47 -

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.

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.

- 48 -

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 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)

- 49 -

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 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

- 50 -

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.

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.

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,

- 51 -

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 Second Closing). Without limiting the generality of the foregoing, the 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).

(H) Each Company (other than KiOR) agrees that it shall subordinate any right of subrogation in respect of any Secured Obligations guaranteed hereby until payment in full of all Secured Obligations (other than contingent indemnification obligations and any other obligations which survive the payment of the Notes or the Second Closing).

(I) Each Company (other than KiOR) further agrees that, as between it, on the one hand, and the Purchasers, on the other hand: (i) the maturity of the Secured Obligations guaranteed hereby may be accelerated as provided herein for the purposes of such Company’s Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Secured Obligations guaranteed hereby; and (ii) in the event of any declaration of acceleration of such Secured Obligations, such Secured Obligations (whether or not due and payable) shall forthwith become due and payable by such Company for the purposes of this Section 12.1.

(J) Each Company (other than KiOR) also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by each Purchaser in enforcing any rights under this Article 12.

12.2 Limitation on Liability. Any term or provision of this Agreement to the contrary notwithstanding, the maximum aggregate amount of the Secured Obligations guaranteed hereunder by any Company will not exceed the maximum amount that can be hereby guaranteed without rendering this Agreement, as it relates to such Company, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

12.3 Successors and Assigns. This Article 12 will be binding upon each Guarantor and its successors and assigns and will inure to the benefit of the successors and assigns of the Purchasers and, in

- 52 -

the event of any transfer or assignment of rights by any Purchaser, the rights and privileges conferred upon that party in this Agreement and in the Notes shall automatically extend to and be vested in such transferee or assignee.

12.4 No Waiver. Neither a failure nor a delay on the part of the Purchasers in exercising any right, power or privilege under this Article 12 will operate as a waiver thereof, nor will a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Purchasers herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which they may have under this Article 12, at law, in equity, by statute or otherwise.

12.5 Modification. No modification, amendment or waiver of any provision of this Article 12, nor the consent to any departure by any Company therefrom, will in any event be effective unless the same is in writing and signed by the Required Purchasers and KiOR and the Company as contemplated by Section 10.3 and then such waiver or consent will be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Company in any case will entitle that Company to any other or further notice or demand in the same, similar or other circumstances.

FOR VALUE RECEIVED, KiOR Inc., a Delaware corporation (the “Company”), hereby promises to pay to the order of [—] (the “Holder” or “Purchaser”), the principal sum of [—] ($[—]) (the “Principal Amount”). This Note is one of a series of Notes issued pursuant to that certain Senior Secured Convertible Promissory Note Purchase Agreement dated October 18, 2013 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.

1. Definitions.

(a) “Additional Shares of Common Stock” means: all shares of Class A Common Stock issued by the Company after the date hereof, other than (i) the following shares of Class A Common Stock and (ii) shares of Class A Common Stock deemed issued pursuant to the following Options and Convertible Securities (clauses (i) and (ii), collectively, “Exempted Securities”): (A) shares of Class A Common Stock issued or issuable upon conversion of the outstanding shares, as of the date of the First Closing, of Class B Common Stock (B) Shares of Class A Common Stock, Options or Convertible Securities issued as a dividend or distribution on Class A Common Stock; (C) shares of Class A Common Stock, Options or Convertible Securities issued by reason of a dividend, stock split, split-up or other distribution on shares of Common Stock that is covered by Section 1(c)(ii) hereof); (D) shares of Class A Common Stock or Options issued to employees or directors of, or contractors, consultants or advisors to, the Corporation or any of its subsidiaries pursuant to any plan, agreement or arrangement approved by the Board of Directors of the Company; (E) shares of Class A Common Stock or Convertible Securities actually issued upon the exercise of Options or shares of Class A Common Stock actually issued upon the conversion or exchange of Convertible Securities, in each case provided such issuance is pursuant to the terms of such Option or Convertible Security; (F) shares of Class A Common Stock, Options or Convertible Securities issued to banks, equipment lessors or other financial institutions, or to real property lessors, pursuant to a debt financing, equipment leasing or real property leasing transaction approved by the Board of Directors of the Company; (G) shares of Class A Common Stock approved by the Holder, (H) warrants to purchase Class A Common Stock and shares

-64-

of Class A Common Stock issued in connection with or otherwise related to the Existing Loan; (I) securities issued by the Company in the Financing Event or the Purchase Agreement; and (J) securities issued pursuant to that certain Class A Common Stock Purchase Agreement dated on or about the date hereof by and between the Company and the purchasers set forth therein.

(b) “Applicable Interest Rate” means: zero percent (0%) per annum.

(c) “Conversion Price” means $2.897, which amount represents 125% of the twenty (20) day VWAP of the Class A Common Stock ending on the trading day preceding the date hereof, as adjusted for any stock splits, dividends, recapitalizations or the like after the date hereof, and as set forth below:

(i) Antidilution Protection.

a) Issuance of Additional Shares of Common Stock. In the event the Company shall at any time after the date hereof and before the first to occur of (i) the one year anniversary of the date hereof and (ii) the conversion of this Note pursuant to the terms hereof, issue Additional Shares of Common Stock, (including Additional Shares of Common Stock deemed to be issued pursuant to the terms hereof), without consideration or for a consideration per share less than the Conversion Price in effect immediately prior to such issue, then the Conversion Price shall be reduced, concurrently with such issue, to a price (calculated to the nearest one-hundredth of a cent) equal to the product of (x) the Conversion Price then in effect and (y) the quotient of (A) the price per share of the Additional Shares of Common Stock so issued and (B) the Conversion Price then in effect.

b) Deemed Issuance of Additional Shares of Common Stock. In the event the Company shall at any time after the date hereof and before the first to occur of the Second Closing or the Maturity Date, issue, grant or sell Options or Convertible Securities (excluding Options or Convertible Securities which are themselves Exempted Securities), regardless of whether such Options or Convertible Securities are immediately exercisable or convertible, and the price per share for which Class A Common Stock is issuable upon the exercise or conversion of such Options or Convertible Securities (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount, if any, received or receivable by the Company as consideration for the grant, issue or sale of such Options or Convertible Securities, plus (y) the aggregate amount of additional consideration, if any, payable to the Company upon the exercise, conversion or exchange of such Options or Convertible Securities, by (ii) the total maximum number of shares of Class A Common Stock issuable upon the exercise, conversion or exchange of all such Options or Convertible Securities) shall be less than the Conversion Price in effect immediately prior to the time of the grant, issue or sale of such Options or Convertible Securities, then the total number of shares of Class A Common Stock issuable upon the exercise, conversion or exchange of all such Options or Convertible Securities shall be deemed to be Additional Shares of Common Stock issued for such price per share as of the date of grant, issue or sale of such Options or Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting the Conversion Price. Except as otherwise provided in Section 1(c)(vii), no adjustment of the Conversion Price shall be made upon the actual issue of such Class A Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issue of such Class A Common Stock upon conversion or exchange of such Convertible Securities. In the event any such Option shall terminate without exercise, the Conversion Price shall be subject to adjustment as provided in Section 1(c)(vii).

-65-

(ii) Adjustment for Stock Splits and Combinations. If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Class A Common Stock, the Conversion Price in effect immediately before that subdivision shall be proportionately decreased so that the number of shares of Class A Common Stock issuable on conversion of the Note shall be increased in proportion to such increase in the aggregate number of shares of Class A Common Stock outstanding. If the Company shall at any time or from time to time after the date hereof combine the outstanding shares of Class A Common Stock, the Conversion Price in effect immediately before the combination shall be proportionately increased so that the number of shares of Class A Common Stock issuable on conversion of the Note shall be decreased in proportion to such decrease in the aggregate number of shares of Class A Common Stock outstanding. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective;

(iii) Adjustment for Certain Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue, or fix a record date for the determination of holders of Class A Common Stock entitled to receive, a dividend or other distribution payable on the Class A Common Stock in additional shares of Class A Common Stock, Convertible Securities or Options, then and in each such event the Conversion Price in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Conversion Price then in effect by a fraction: (1) the numerator of which shall be the total number of shares of Class A Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (2) the denominator of which shall be the total number of shares of Class A Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Class A Common Stock issuable (or issuable upon conversion or exercise thereof in the case of dividends or other distribution of Convertible Securities or Options) in payment of such dividend or distribution. Notwithstanding the foregoing, if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Conversion Price shall be adjusted pursuant to this subsection as of the time of actual payment of such dividends or distributions.

(iv) Adjustment for Merger or Reorganization, etc. If there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the Company in which the Class A Common Stock is converted into or exchanged for securities, cash or other property then, following any such reorganization, recapitalization, reclassification, consolidation or merger, the Note shall thereafter be convertible in lieu of the Class A Common Stock into which it was convertible prior to such event, into the kind and amount of securities, cash or other property which a holder of the number of shares of Class A Common Stock of the Company issuable upon conversion of the Note immediately prior to such reorganization, recapitalization, reclassification, consolidation or merger would have been entitled to receive pursuant to such transaction; and, in such case, appropriate adjustment (as determined in good faith by the Board of Directors of the Company) shall be made in the application of the provisions in this Section 1(b)(iv) with respect to the rights and interests thereafter of the Holder, to the end that the provisions set forth in this Section 1(b) (including provisions with respect to changes in and other adjustments of the Conversion Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities or other property thereafter deliverable upon the conversion of the Note.

-66-

(v) Adjustments for Other Dividends and Distributions. In the event the Company at any time or from time to time after the date hereof shall make or issue, or fix a record date for the determination of holders of Class A Common Stock entitled to receive, a dividend or other distribution payable in cash, securities of the Company (other than a distribution of shares of Class A Common Stock in respect of outstanding shares of Class A Common Stock) or in other property and the provisions above do not apply to such dividend or distribution, then and in each such event the holder of a Note shall receive, upon conversion of the Note, a dividend or other distribution of such securities, cash or other property in an amount equal to the amount of such securities or other property as they would have received if the Note had been converted into Class A Common Stock on the date of such event.

(vi) [Reserved]

(vii) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price, additional consideration payable or conversion rate provided for in any Option or Convertible Security referred to in Section 1(c)(i)(b) hereof, shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Conversion Price in effect at the time of such event shall forthwith be readjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold. On the termination without exercise of any Option for which any adjustment was made pursuant to Section 1(c) or any right to convert or exchange Convertible Securities for which any adjustment was made pursuant to Section 1(c) (including without limitation upon the redemption or purchase for consideration of such Convertible Securities by the Company), the Conversion Price then in effect hereunder shall forthwith be changed to the Conversion Price which would have been in effect at the time of such termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such termination, never been issued.

c) Other Events. In the event that the Company (or any Subsidiary) shall take any action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of the type contemplated by the provisions of this Section 1(c)(i)(b) but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Board of Directors of the Company shall in good faith determine and implement an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder, provided that no such adjustment pursuant to this Section will increase the Conversion Price as otherwise determined pursuant to this Section 1(c); provided further that if the Holder does not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Board of Directors of the Company and the Holder shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding and whose fees and expenses shall be borne by the Company.

(d) “Conversion Shares” means shares of the Class A Common Stock of the Company.

(e) “Convertible Securities” means any evidences of indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Class A Common Stock, but excluding Options.

-67-

(f) “Maturity Date” means February 1, 2020.

(g) “Option” means rights, options or warrants to subscribe for, purchase or otherwise acquire Class A Common Stock or Convertible Securities.

(h) “PIK Interest” means interest paid in kind by adding such interest then due to the unpaid Principal Amount.

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 fiscal quarter, beginning on January 1, 2014, provided that interest may, at Company’ 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. Unless earlier converted into Conversion Shares in accordance with Section 4, 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. Conversion of Notes.

4.1 Mandatory Conversion. (i) If on or before the one year anniversary of the First Closing, the Company consummates the Financing Event, then upon the first to occur after the consummation of the Financing Event of (A) the average closing price of the Class A Common Stock exceeds 150% of the Conversion Price in any thirty (30) day period (the “Pricing Event”) or (B) the one year anniversary of the First Closing occurs, then in such event and simultaneously with such event, as applicable, 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 automatically, without any additional action of the Holder, be converted into Conversion Shares and (ii) if the Company consummates the Financing Event after the one year anniversary of the First Closing, then in such event and simultaneously with such event 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 automatically, without any additional action of the Holder, be converted into Conversion Shares. The number

-68-

of Conversion Shares to be issued upon such conversion shall be equal to the quotient obtained by dividing the Principal Amount (which, for clarification, will include any previously paid PIK Interest) and all accrued but unpaid interest hereunder (including any PIK Interest) on the date of conversion, by the Conversion Price. At least five (5) days prior to the closing of the Second Closing, the Company shall deliver notice to the Holder at the address last shown on the records of the Company for the Holder or given by the Holder to the Company for the purpose of notice (or, if no such address appears or is given, at the place where the principal executive office or residence of the Holder is located), notifying the Holder of the conversion to be effected.

4.2 Optional Conversion. Subject to the terms hereof, at any time prior to the consummation by the Company of a Change in Control or the Maturity Date, at the option of the Holder delivered in writing to the Company at least three (3) days prior to the Change in Control or Maturity Date, as applicable, the Principal Amount (which, for clarification, will include any previously paid PIK Interest) and all accrued but unpaid interest hereunder (including any PIK Interest) may be converted into Conversion Shares immediately prior to (but subject to) the consummation of, such Change of Control or Maturity Date, as applicable. The number of Conversion Shares to be issued upon such conversion shall be equal to the quotient obtained by dividing the Principal Amount (which, for clarification, will include any previously paid PIK Interest) and all accrued but unpaid interest hereunder (including any PIK Interest) by the Conversion Price. At least ten (10) days prior to the closing of a Change in Control, the Company shall deliver notice to the Holder at the address last shown on the records of the Company for the Holder or given by the Holder to the Company for the purpose of notice (or, if no such address appears or is given, at the place where the principal executive office or residence of the Holder is located), notifying the Holder of such proposed Change in Control, the anticipated consummation date of same, and the material terms thereof.

4.3 Limitations on Conversion. Notwithstanding anything in this Note to the contrary, the Holder acknowledges and agrees that the Company shall not have any obligation to issue, and shall not issue, Conversion Shares unless and until the Company has obtained the approval of its stockholders of the issuance of this Note and the issuance of the Conversion Shares to the Holder of this Note. The Company agrees to use commercially reasonable efforts to obtain such approval of its stockholders. To the extent that the Holder is also a stockholder of the Company, the Holder agrees to vote all shares held by it or over which it has voting control in favor of the issuance of this Note and the issuance of the Conversion Shares.

4.4 No Fractional Shares. Upon the conversion of a Note into Conversion Shares, any fraction of a share will be rounded down to the next whole share of the Conversion Shares and no fractional shares shall be issued upon conversion of this Note. In lieu of the Company issuing any fractional shares to the Holder upon the conversion of this Note, the Company shall pay to the Holder an amount equal to the product obtained by multiplying the applicable Conversion Price by the fraction of a share not issued pursuant to the previous sentence.

4.5 Mechanics of Conversion. The Company shall not be required to issue or deliver the Conversion Shares until the Holder has surrendered the original Note to the Company or delivered an affidavit of loss related thereto together with an agreement to indemnify the Company for any losses associated with the loss of such Note. Upon the conversion of this Note, the Holder shall have no further rights under the Note, whether or not the Note is surrendered, and on and after such date, the persons entitled to receive the Conversion Shares issuable upon such conversion shall be treated for all purposes as the record holder of such Conversion Shares. Upon conversion of this Note, the Company shall be forever released from all its obligations and liabilities under this Note and this Note shall be deemed of no further force or effect, whether or not the original of this Note has been delivered to the Company for cancellation; provided that the foregoing shall not limit any rights of the Holder under the Purchase Agreement. As promptly as practicable after the conversion of this Note, the Company at its expense shall issue and deliver to the Holder, upon

-69-

surrender of the original Note, a certificate or certificates for the number of full Conversion Shares issuable upon such conversion, including a check payable to the Holder for any cash amounts payable as described in Section 4.4.

4.6 Cooperation. For the avoidance of doubt, the Company shall be obligated to comply with Section 6.16 of the Purchase Agreement in connection with any potential conversion of this Note to Conversion Shares, including making any timely filings required under the HSR Act, prior to any such conversion.

5. 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.

6. Payment; Prepayment.

6.1 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. Except as set forth in Section 5 hereof, prepayment of principal, together with accrued interest, may not be made prior to the Maturity Date without the consent of the Required Purchasers. Prepayment of this Note shall not occur without the Holder’s consent; if prepayment is consented to by the Holder, (a) it will be without any prepayment penalties and (b) interest will no longer continue to accrue on any prepaid principal amounts after such prepayments.

6.2 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.

7. Remedies. The acceleration of the obligations under this Note and the exercise of remedies under this Note shall be governed by the provisions of Article 9 of the Purchase Agreement. The Company waives presentment, demand, protest or (except as expressly provided in the Purchase Agreement or the other Transaction Documents) notice of any kind, all of which are hereby expressly waived. The Company will give prompt written notice to the Holder of the occurrence of any and all Events of Default.

-70-

8. 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.

9. 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.

10. 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.

11. 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.

12. 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. Any counterpart delivered electronically by .pdf transmission or by facsimile shall be binding to the same extent as an original counterpart with regard to any agreement subject to the terms hereof or any amendment thereto.

WHEREAS:

In connection with the Senior Secured Convertible Promissory Note Purchase Agreement, dated as of October 18, 2013, by and among the Company, the Purchasers and the other parties thereto (the “Purchase Agreement”), the Company has agreed, upon the terms and subject to the conditions contained therein, to issue and sell to the Purchasers (i) the Notes (as defined in the Purchase Agreement) and (ii) subject to the closing of a Financing Event (as defined in the Purchase Agreement), shares of Class A Common Stock (which, together with the Conversion Shares are referred to herein as the “Shares”).

To induce the Purchasers to execute and deliver the Purchase Agreement, the Company has agreed to provide certain registration rights under the Securities Act of 1933, as amended, and the rules and regulations thereunder, or any similar successor statute (collectively, the “Securities Act”), and applicable state securities laws.

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Purchasers hereby agree as follows:

ii. “Conversion Shares” means shares of Class A Common Stock issued or issuable upon conversion of the Notes.

iii. “Excluded Registration” means (i) a registration relating to the sale of securities to employees of the Company or a subsidiary pursuant to a stock option, stock purchase, or similar plan; (ii) a registration relating to an SEC Rule 145 transaction; or (iii) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities.

iv. “Purchasers” means the Purchasers and any transferees or assignees who agree to become bound by the provisions of this Agreement in accordance with Section 10 hereof.

v. “Register,” “Registered,” and “Registration” refer to a registration effected by preparing and filing a Registration Statement or Statements in compliance with the Securities Act and pursuant to Rule 415 under the Securities Act or any successor rule providing for offering securities on a continuous basis (“Rule 415”), and the declaration or ordering of effectiveness of such Registration Statement by the United States Securities and Exchange Commission (the “SEC”).

vi. “Registrable Securities” means (a) the Shares and (b) any shares of capital stock issued or issuable, from time to time (with any adjustments), in respect of the Shares by virtue of any stock split, stock dividend, recapitalization or similar event; provided, however, that shares of Class A Common Stock that are Registrable Securities shall cease to be Registrable Securities upon the earliest of (A) the date such shares become eligible for sale pursuant to Rule 144(b)(1)(i) under the Securities Act; provided that a period of at least one year, as determined in accordance with paragraph (d) of Rule 144 under the Securities Act, has elapsed since the later of the date such shares were acquired from the Company or an affiliate of the Company, (B) the date that such shares are sold (I) pursuant to a registration statement, (II) to or through a broker, dealer or underwriter in a public securities transaction and/or (III) in a transaction exempt from the registration and prospectus delivery requirements of the Securities Act such that all transfer restrictions and restrictive legends with respect thereto, if any, are removed upon the consummation of such sale, (C) five (5) years after the date of this Agreement, or (D) any sale or transfer to any person or entity which by virtue of Section 10 of this Agreement is not entitled to the rights provided by this Agreement.

B. Capitalized terms used herein and not otherwise defined herein shall have the respective meanings set forth in the Purchase Agreement.

2. REGISTRATION.

A. MANDATORY REGISTRATION.

i. The Company shall file with the SEC and use its reasonable best efforts to cause to become effective a Registration Statement on Form S-3 (or, if Form S-3 is not then available, on such form of Registration Statement as is then available to effect a Registration of all of the Registrable Securities) covering the resale of the Registrable Securities as soon as practicable and in no event later than April [—], 2014 (the “Initial Registration Statement”). The Initial Registration Statement filed hereunder, to the extent allowable under the Securities Act, shall state that such Initial Registration Statement also covers such indeterminate number of additional shares of Class A Common Stock as may become issuable upon conversion of the Conversion Shares to prevent dilution resulting from stock splits, stock dividends or similar transactions.

ii. Notwithstanding the registration obligations set forth in this Section 2, in the event the SEC informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company shall promptly inform each of the Purchasers and use its commercially reasonable efforts to

- 2 -

(a) file amendments to the Initial Registration Statement as required by the SEC and/or (b) withdraw the Initial Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the SEC, on Form S-3 or such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its commercially reasonable efforts to advocate with the SEC for the registration of all of the Registrable Securities in accordance with the SEC Guidance, including without limitation, Compliance and Disclosure Interpretation 612.09 of the rules adopted under the Securities Act.

iii. Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used commercially reasonable efforts to advocate with the SEC for the registration of all or a greater number of Registrable Securities), unless otherwise directed in writing by a holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement will first be reduced by (a) Registrable Securities not acquired pursuant to the Purchase Agreement (whether pursuant to registration rights or otherwise) and, if Registrable Securities (as defined in the Stock Registration Rights Agreement) are included in such offering, Registrable Securities (as defined in the Stock Registration Rights Agreement) not acquired pursuant to the Stock Purchase Agreement and (b) second by Registrable Securities that are Shares and, if Registrable Securities (as defined in the Stock Registration Rights Agreement) are included in such offering, Registrable Securities (as defined in the Stock Registration Rights Agreement) that are shares issued pursuant to the Stock Purchase Agreement (applied, in the case that some shares may be registered, to all such holders on a pro rata basis based on the total number of unregistered shares held by all such holders, subject to a determination by the SEC that the shares of certain holders must be reduced first based on the number of shares held by such holders).

iv. In the event the Company amends the Initial Registration Statement or files a New Registration Statement, as the case may be, under clause ii. above, the Company will use its commercially reasonable efforts to file with the SEC, as promptly as allowed by the SEC or the SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended, or the New Registration Statement (the “Remainder Registration Statements”).

v. In no event shall the Company include any securities other than Registrable Securities and Registrable Securities (as defined in the Stock Registration Rights Agreement) on any Registration Statement (or enter into any agreement which would require the Company to include any securities other than the Registrable Securities and Registrable Securities (as defined in the Stock Registration Rights Agreement)) on any Registration Statement filed pursuant to this Section 2.A. without the prior written consent of the Purchasers holding at least a majority of the Registrable Securities then outstanding.

B. ALTERNATIVE REGISTRATION.

i. Without limiting the obligations of the Company pursuant to Section 2.A or any remedy available to the Purchasers for the breach thereof, if the Company cannot effect a

- 3 -

registration pursuant to Section 2(A) hereof, and the Company receives a request from one or more Purchasers that the Company file a Registration Statement on Form S-1 with respect to at least twenty five percent (25%) of the Registrable Securities, then the Company shall (x) within ten (10) days after the date such request is given, give notice thereof (the “Demand Notice”) to all Purchasers; and (y) as soon as practicable, and in any event within seventy-five (75) days after the date such request is given by the Initiating Holders, file a Registration Statement on Form S-1 under the Securities Act covering all Registrable Securities that the Purchasers have requested to be registered as specified by notice given by each such Purchaser to the Company within twenty (20) days of the date the Demand Notice is given. If the Purchasers intend to distribute the Registrable Securities covered by their request by means of an underwriting, the right of any Purchaser to include such Purchaser’s Registrable Securities in such registration shall be conditioned upon such Purchaser’s participation in such underwriting and the inclusion of such Purchaser’s Registrable Securities in the underwriting to the extent provided herein. In the event the Purchasers intend to distribute the Registrable Securities by means of an underwriting, and the underwriters advise the Purchasers in writing that marketing factors require a limitation on the number of shares to be underwritten, then the number of Registrable Securities that may be included in the underwriting shall be allocated among such Purchasers, in proportion (as nearly as practicable) to the number of Registrable Securities owned by each Purchaser or in such other proportion as shall mutually be agreed to by all such selling Purchasers and other selling holders; provided that if any Registrable Securities (as defined in the Stock Registration Rights Agreement) are included in such underwriting, then the number of Registrable Securities that may be included in the underwriting shall be allocated among the Purchasers requesting registration and the other holders of Registrable Securities (as defined in the Stock Registration Rights Agreement) requesting registration, in proportion (as nearly as practicable) to the number of Registrable Securities and Registrable Securities (as defined in the Stock Registration Rights Agreement) owned by each Purchaser or other selling holder or in such other proportion as shall mutually be agreed to by all such selling Purchasers and other selling holders. The Company shall have no obligation to effect, or to take any action to effect, any registration pursuant to this Section 2(B)(i) after the Company has effected two registrations pursuant to this Section 2(B)(i).

ii. Without limiting any obligation of the Company hereunder or under the Purchase Agreement, if there is not an effective Registration Statement covering all of the Registrable Securities or the prospectus contained therein is not available for use and the Company proposes to register (including, for this purpose, a registration effected by the Company for stockholders other than the Purchasers) any of its Class A Common Stock under the Securities Act in connection with the public offering of such securities solely for cash (other than in an Excluded Registration), the Company shall, at such time, promptly give each Purchaser notice of such registration. Upon the request of each Purchaser given within twenty (20) days after such notice is given by the Company, the Company shall cause to be registered all of the Registrable Securities that each such Purchaser has requested to be included in such registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2(B)(ii) before the effective date of such registration, whether or not any Purchaser has elected to include Registrable Securities in such registration. In connection with any offering involving an underwriting of shares of the Company’s capital stock pursuant to this Section 2(B)(ii), the Company shall not be required to include any of the Purchasers’ Registrable Securities in such underwriting unless the Purchasers accept the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not adversely impact the offering by the Company. If the total number of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the number of securities to be sold (other than by the Company) that the underwriters in their discretion determine would adversely impact the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters and the Company in their sole

- 4 -

discretion determine will not adversely impact the offering. If the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that are included in such offering shall be allocated among the selling Purchasers in proportion (as nearly as practicable to) the number of Registrable Securities owned by each selling Purchaser or in such other proportions as shall mutually be agreed to by all such selling Purchasers. Notwithstanding the foregoing, in no event shall the number of Registrable Securities and Registrable Securities (as defined in the Stock Registration Rights Agreement) included in the offering be reduced below twenty-five percent (25%) of the total number of securities included in such offering.

C. PAYMENTS BY THE COMPANY.

i. If the Initial Registration Statement or the New Registration Statement, as the case may be, is not declared effective by the SEC on or before 180 days from the date of this Agreement (the “Registration Deadline”) or, (ii) if, after a Registration Statement has been declared effective by the SEC, sales of any of the Registrable Securities covered by such Registration Statement cannot be made pursuant to such Registration Statement because such Registration Statement has been suspended (by reason of a stop order or the Company’s failure to update the Registration Statement or otherwise) except as a result of a permitted Suspension under Section 9, or is otherwise no longer effective, then, without limiting the remedies available to Purchasers pursuant to Section 2(C)(iv), then the Company will make payments to the Purchasers in such amounts and at such times as shall be determined pursuant to this Section 2(C), as liquidated damages and not as a penalty for such delay in or reduction of their ability to sell the Registrable Securities (which remedy shall constitute the Purchasers exclusive monetary remedy). In such event, the Company shall pay to each Purchaser an amount equal to one and one-half percent (1.5%) of the aggregate purchase price paid by Purchaser pursuant to the Purchase Agreement for the Shares with respect to which any unregistered Registrable Securities are then held by the Purchaser for each consecutive or non-consecutive thirty (30) day period after the Registration Deadline and prior to the date the Initial Registration Statement or the New Registration Statement, as the case may be, is declared effective by the SEC, or during which sales of any Registrable Securities covered by a Registration Statement cannot be made pursuant to any such Registration Statement after the Registration Statement has been declared effective; provided, however, that there shall be excluded from each such period any delays which are attributable to changes (other than corrections of Company mistakes with respect to information previously provided by the Purchasers) required by the Purchasers in the Registration Statement with respect to information relating to the Purchasers, including, without limitation, changes to the plan of distribution. Such amounts shall be paid in cash within five (5) Trading Days after the end of each thirty (30) day period that gives rise to such obligation.

ii. Notwithstanding the foregoing, in no event shall the Company be obligated to make payments hereunder (a) to more than one Purchaser in respect of the same Registrable Securities for the same period of time or (b) to any one Purchaser in an aggregate amount that exceeds ten percent (10%) of the aggregate price paid by such Purchaser for such Shares.

iii. The Company shall not be liable for liquidated damages under this Agreement as to any Registrable Securities which are not permitted by the SEC to be included in the Initial Registration Statement or the New Registration Statement due solely to SEC Guidance relating to the inclusion of such Registrable Securities in a Registration Statement from the time that it is determined that such Registrable Securities are not permitted to be registered. In such case, the liquidated damages shall be calculated to only apply to the Registrable Securities which are permitted in accordance with SEC Guidance relating to the inclusion of such Registrable Securities in a Registration Statement to be included in such Initial Registration Statement or such New Registration Statement.

- 5 -

iv. Notwithstanding the foregoing, nothing shall preclude the Purchaser from pursuing or obtaining any available specific performance or other equitable relief in accordance with applicable law.

3. OBLIGATIONS OF THE COMPANY.

In connection with the registration of the Registrable Securities, the Company shall have the following obligations:

A. The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to each Registration Statement and the prospectus used in connection with each Registration Statement as may be necessary to keep each such Registration Statement effective pursuant to Rule 415 at all times until no Registrable Securities thereunder remain outstanding (the “Registration Period”), and, during such period, comply with the provisions of the Securities Act in order to enable the disposition of all Registrable Securities of the Company covered by the Registration Statement until such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in the Registration Statement.

B. In connection with the Company’s registration obligations hereunder, the Company shall (a) not less than five (5) Trading Days prior to the filing of each Registration Statement and not less than one (1) Trading Day prior to the filing of any related prospectus or any amendment or supplement thereto (except for Annual Reports on Form 10-K, and Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and any similar or successor reports), (i) furnish to each Purchaser copies of such Registration Statement, prospectus or amendment or supplement thereto, as proposed to be filed, which documents will be subject to the review of the Purchasers (it being acknowledged and agreed that if a Purchaser does not object to or comment on the aforementioned documents within such five (5) Trading Day or one (1) Trading Day period, as the case may be, then such Purchaser shall be deemed to have consented to and approved the use of such documents) and (ii) use commercially reasonable efforts to cause its officers and directors, counsel and independent registered public accountants to respond to such inquiries as shall be necessary to conduct a reasonable investigation within the meaning of the Securities Act. The Company shall not file any Registration Statement or amendment or supplement thereto in a form to which any Purchaser reasonably objects in good faith; provided that, the Company is notified of such objection in writing within the five (5) Trading Day or one (1) Trading Day period described above, as applicable.

C. The Company will use reasonable best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction.

D. In connection with the effectiveness of each Registration Statement, the Company shall furnish to each Purchaser whose Registrable Securities are included in the Registration Statement within one (1) Trading Day of the date of effectiveness of the Registration Statement or any amendment thereto, a notice stating that the Registration Statement or amendment has been declared effective; and such number of copies of a prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as such Purchaser may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Purchaser.

E. The Company shall use its reasonable best efforts to (i) register and qualify the Registrable Securities covered by Registration Statements under such other securities or “blue sky” laws of such jurisdictions in the United States as each Purchaser who holds Registrable Securities being

- 6 -

offered reasonably requests, (ii) prepare and file in those jurisdictions such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (a) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(C), (b) subject itself to general taxation in any such jurisdiction, (c) file a general consent to service of process in any such jurisdiction, (d) provide any undertakings that cause the Company undue expense or burden, or (e) make any change in its certificate of incorporation or bylaws, which in each case the Board of Directors of the Company determines to be contrary to the best interests of the Company and its stockholders.

F. The Company shall notify each Purchaser who holds Registrable Securities of the time when a supplement to any prospectus forming a part of a Registration Statement has been filed and of any request by the SEC for the amending or supplementing of such Registration Statement or prospectus. If the Company has delivered a Prospectus and after having done so the prospectus is amended to comply with the requirements of the Securities Act, the Company shall promptly notify each Purchaser who holds Registrable Securities covered by such prospectus and, if requested, such Purchasers shall immediately cease making offers of Registrable Securities pursuant to such prospectus and return all copies of such prospectus to the Company. The Company shall promptly provide the Purchasers with revised prospectuses and, following receipt of the revised prospectuses, the Purchasers shall be free to resume making offers of the Registrable Securities.

G. The Company shall provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities not later than the effective date of the Initial Registration Statement or the New Registration Statement, as applicable.

H. The Company shall cooperate with the Purchasers who hold Registrable Securities to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be offered pursuant to the Registration Statements and enable such certificates to be in such denominations or amounts, as the case may be, as Purchasers may reasonably request and registered in such names as the Purchasers may request.

I. At the reasonable request of any Purchaser holding Registrable Securities covered by a Registration Statement, the Company shall prepare and file with the SEC such amendments (including post effective amendments) and supplements to such Registration Statement and the prospectus used in connection with such Registration Statement as may be necessary in order to change the plan of distribution set forth in such Registration Statement.

J. The Company shall use its reasonable best efforts to cause all Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or trading system on which similar securities issued by the Company are then listed.

K. The Company shall cooperate with any registered broker though which a Purchaser proposes to sell its Registrable Securities in effecting a filing with FINRA pursuant to FINRA Rule 5110 as requested by any of the Purchasers and the Company shall pay the filing fee required for such filing within two (2) business days of the request therefor.

- 7 -

4. OBLIGATIONS OF THE PURCHASERS. In connection with the registration of the Registrable Securities, the Purchasers shall have the following obligations:

A. It shall be a condition precedent to the obligations of the Company under Sections 2 and 3 with respect to the Registrable Securities of a particular Purchaser that such Purchaser shall furnish to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request. At least five (5) Trading Days prior to the first anticipated filing date of the Initial Registration Statement or the New Registration Statement, as the case may be, the Company shall notify each Purchaser of the information the Company requires from each such Purchaser.

B. Each Purchaser, by such Purchaser’s acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of each Registration Statement hereunder, unless such Purchaser has notified the Company in writing of such Purchaser’s election to exclude all of such Purchaser’s Registrable Securities from such Registration Statement.

C. Each Purchaser agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Sections 3(D) or 9, such Purchaser will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such Purchaser’s receipt of the copies of the supplemented or amended prospectus contemplated by Sections 3(D) or 9.

5. EXPENSES OF REGISTRATION. All reasonable expenses incurred by the Company or the Purchasers in connection with registrations, filings or qualifications pursuant to Sections 2 and 3 above, including, without limitation, all registration, listing and qualifications fees, printers and accounting fees, the fees and disbursements of counsel for the Company and the fees and disbursements of one counsel selected by the Purchasers, shall be borne by the Company, excluding underwriting discounts, selling commissions and similar costs which shall be borne by the Purchasers.

6. INDEMNIFICATION. In the event any Registrable Securities are included in a Registration Statement under this Agreement:

A. To the fullest extent permitted by law, notwithstanding any termination of this Agreement, the Company will indemnify, hold harmless and defend (i) each Purchaser who holds such Registrable Securities, each of their (ii) the directors, officers, partners, members, managers, stockholders, employees and agents, (iii) each person who controls any Purchasers within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), if any, and (iv) each of the directors, officers, partners, members, managers, stockholders, employees and agents of each such controlling person (each, an “Indemnified Person”), from and against any and all losses, claims, damages, liabilities, costs, (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, together with actions, proceedings or inquiries by any regulatory or self-regulatory organization, whether commenced or threatened, in respect thereof, “Claims”) to which any of them may become subject insofar as such Claims arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or the omission or alleged omission to state therein a material fact required to be stated or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus if used prior to the effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading, or (iii) any violation or alleged violation by the Company of the

- 8 -

Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities (the matters in the foregoing clauses (i) through (iii), collectively, “Violations”). Subject to the restrictions set forth in Section 6(C) with respect to the number of legal counsel, the Company shall reimburse the Purchasers and each other Indemnified Person, promptly as such expenses are incurred and are due and payable, for any reasonable legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the obligations of the Company contained in this Section 6(A): (i) shall not apply to the extent that a Claim arises out of or is based upon (A) a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person expressly for use in the Registration Statement or any such amendment thereof or supplement thereto, (B) the failure of a Purchaser to comply with Section 4(C) or (C) the use by a Purchaser in connection with any sale or sales of Registrable Securities of a prospectus containing any untrue statement or omission of a material fact following notification by the Company in writing that such prospectus contains an untrue statement or omission of a material fact and receipt by the Purchaser of a corrected prospectus; and (ii) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Purchasers pursuant to Section 10 hereof.

B. Each Purchaser who holds such Registrable Securities agrees severally and not jointly to indemnify, hold harmless and defend, to the same extent and in the same manner set forth in Section 6(A), the Company, each of its directors, each of its officers who signs the Registration Statement, its employees, agents and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and any other stockholder selling securities pursuant to the Registration Statement or any of its directors or officers or any person who controls such stockholder within the meaning of the Securities Act or the Exchange Act (collectively and together with an Indemnified Person, an “Indemnified Party”), against any Claim to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise, to the extent that such Claim arises out of or is based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Purchaser expressly for use in connection with such Registration Statement; and subject to Section 6(C) such Purchaser will reimburse any legal or other expenses (promptly as such expenses are incurred and are due and payable) reasonably incurred by them in connection with investigating or defending any such Claim; provided, however, that (I) the obligations of a Purchaser contained in this Section 6(B) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Purchaser, which consent shall not be unreasonably withheld, and (II) the Purchaser shall be liable under this Agreement (including this Section 6(B) and Section 7) for only that amount as does not exceed the gross proceeds actually received by such Purchaser as a result of the sale of Registrable Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Purchasers pursuant to Section 10 hereof.

C. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the threat or commencement of any action (including any governmental action), such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that such

- 9 -

indemnifying party shall not be entitled to assume such defense and an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential conflicts of interest between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding or the actual or potential defendants in, or targets of, any such action include both the Indemnified Person or the Indemnified Party and the indemnifying party and any such Indemnified Person or Indemnified Party reasonably determines, based upon the reasonable opinion of counsel, that there may be legal defenses available to such Indemnified Person or Indemnified Party which are in conflict with those available to such indemnifying party. The indemnifying party shall pay for only one separate legal counsel for the Indemnified Persons or the Indemnified Parties, as applicable, and such legal counsel shall be selected by Purchasers holding a majority-in-interest of the Registrable Securities included in the Registration Statement to which the Claim relates (with the approval of the Purchasers if it holds Registrable Securities included in such Registration Statement), if the Purchasers are entitled to indemnification hereunder, or by the Company, if the Company is entitled to indemnification hereunder, as applicable. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is actually prejudiced in its ability to defend such action.

D. The Indemnified Party shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party which relates to such action or claim.

E. No indemnifying party shall, except with the consent of each Indemnified Party (which consent shall not be unreasonably withheld), consent to entry of any judgment or enter into any settlement which does not include the giving by the claimant to such Indemnified Party a release from all liability in respect to such claim or litigation.

7. CONTRIBUTION. To the extent any indemnification by an indemnifying party required by the terms of this Agreement is prohibited or limited by law, the indemnifying party, in lieu of indemnifying the Indemnified Party, agrees to contribute with respect to any amounts for which it would otherwise be liable under Section 6 up to the amount paid or payable by the indemnifying party as a result of the Claims in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the Indemnified Person or Indemnified Party, as the case may be, on the other hand, with respect to the Violation giving rise to the applicable Claim; provided, however, that (i) no contribution shall be made under circumstances where the maker would not have been liable for indemnification under the fault standards set forth in Section 6, (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of such fraudulent misrepresentation, and (iii) contribution (together with any indemnification or other obligations under this Agreement) by any seller of Registrable Securities shall be limited in amount to the amount of gross proceeds received by such seller from the sale of such Registrable Securities. The relative fault of the Company and the Purchasers shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material fact related to information supplied by the Company or the Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

8. REPORTS UNDER THE EXCHANGE ACT. With a view to making available to the Purchasers the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of

- 10 -

the SEC that may at any time permit each Purchaser to sell securities of the Company to the public, so long as the Registration Statement is effective and such Purchaser holds Registrable Securities, without registration (“Rule 144”), the Company agrees to:

i. file with the SEC in a timely manner and make and keep available all reports and other documents required of the Company under the Securities Act and the Exchange Act so long as the Company remains subject to such requirements and the filing and availability of such reports and other documents is required for the applicable provisions of Rule 144; and

ii. furnish to each Purchaser so long as such Purchaser owns Registrable Securities, promptly upon request, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Purchasers to sell such securities under Rule 144 without registration.

9. SUSPENSION OF USE OF PROSPECTUS. Subject to Section 2(C), the Company may, by written notice to the Purchasers, (i) delay the filing of, or effectiveness of, a Registration Statement; or (ii) suspend such Registration Statement after effectiveness and require that the Purchasers immediately cease sales of Registrable Securities pursuant to such Registration Statement, if (a) the Company reasonably believes that there is or may be in existence material nonpublic information or events involving the Company, the failure of which to be disclosed in the prospectus included in the registration statement would result in a Violation and that the Company needs time to prepare an amendment or supplement to disclose such information or (b) the Company reasonably believes that the disclosure of such information is not, in the good faith judgment of the Board of Directors of the Company, in the best interests of the Company, in which case the Company shall furnish to the Purchasers a certificate signed by the Chairman of the Board of Directors of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would not be in the best interests of the Company to disclose such material nonpublic information or events in the prospectus included in the registration statement (a “Suspension”). The Company shall not disclose such information or events to any Purchaser. If the Company requires the Purchasers to cease sales of Registrable Securities pursuant to a Suspension, the Company shall, as promptly as practicable following the termination of the circumstance which entitled the Company to do so, take such actions as may be necessary to reinstate the effectiveness of the Registration Statements covering such Registrable Securities, and/or give written notice to the Purchasers authorizing them to resume sales pursuant to the Registration Statements. If, as a result thereof, the prospectuses included in the Registration Statements have been amended to comply with the requirements of the Securities Act, the Company shall enclose such revised prospectuses with the notice to the Purchasers given pursuant hereto, and the Purchasers shall make no offers or sales of Registrable Securities pursuant to the Registration Statements other than by means of such revised prospectus. The Company shall not cause a Suspension on more than two occasions during any twelve (12) month period or for more than thirty (30) days per such occasion.

10. ASSIGNMENT OF REGISTRATION RIGHTS. The rights of the Purchasers hereunder, including the right to have the Company register Registrable Securities pursuant to this Agreement, shall be automatically assignable by each Purchaser to any Permitted Transferee under the Purchase Agreement to which all or any portion of the Registrable Securities are transferred if: (i) the Purchaser agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company after such assignment, (ii) the Company is furnished with written notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights are being transferred or assigned, (iii) the transferee or assignee agrees in writing for the benefit of the Company to be bound by all of the provisions contained herein, and (iv) such transfer shall have been

- 11 -

made in accordance with the applicable requirements of the Purchase Agreement; provided that in the event that only a portion of the Registrable Securities of such Purchaser are transferred, only the Purchaser or only one Permitted Transferee designated by such Purchaser shall have the right to exercise rights hereunder on behalf of all holders of such Purchaser’s Registrable Securities.

11. AMENDMENT OF REGISTRATION RIGHTS. Provisions of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with written consent of the Company and Purchasers holding at least a majority of the Registrable Securities then outstanding. Unless a Purchaser otherwise agrees, each amendment hereto must similarly affect each Purchaser. Any amendment or waiver effected in accordance with this Section 11 shall be binding upon each Purchaser and the Company.

12. UNDERWRITING. If at any time or from time to time during the effectiveness of a Registration Statement the Purchasers holding a majority of Registrable Securities propose to sell twenty five percent (25%) or more of the Registrable Securities held by such Purchasers, such Purchasers may, by notice to the Company, require that such sale occur through a firm commitment underwritten offering (or any other type of underwritten offering specified by such Purchasers) and, in such event, (i) the Company will promptly give written notice of such planned underwritten offering to all other Purchasers holding of Registrable Securities and will include in such registration (subject to any cutbacks demanded by the managing underwriter, which shall be imposed pro rata among the Purchasers holding such Registrable Securities on the basis of the number of Registrable Securities owned by each such Purchasers and subject to the other provisions of this Agreement) all Registrable Securities with respect to which the Company has received written requests for inclusion therein within ten (10) business days after the receipt of the Company’s notice, (ii) the Company shall have the right to select the managing underwriter, subject to the approval (which may not be unreasonably withheld or denied) of the Purchasers holding a majority of the Registrable Securities to be included in such offering, and (iii) the Company shall promptly amend the Registration Statement to include any information reasonably requested to be included therein by the underwriters or Purchasers holding Registrable Securities. Purchasers holding Registrable Securities may request an underwritten offering pursuant to this Section 12 on not more than four (4) occasions in the aggregate (provided that no more than two (2) requests may be made in any one calendar year and a minimum of 90 days must elapse between the making of any such requests), it being understood that (x) the foregoing limitations applicable to underwritten offerings shall not be deemed to limit the obligations of the Company under this Agreement to keep the Registration Statement effective for the time period specified therein for use in connection with non-underwritten offerings and (y) the Purchasers holding Registrable Securities requesting such underwritten offering will be entitled to withdraw such request (such withdrawal to be effective only if (A) made within forty (40) days of the Company’s delivery of the notice to holders contemplated by clause (i) of this Section 12 or (B) made upon the failure to sell at least fifty percent (50%) of the Registrable Securities requested to be included in such underwritten offering. If requested by the underwriters for any underwritten offering pursuant to a registration contemplated by this Section 12, the Company shall enter into a customary underwriting agreement with the underwriters for such offering. Any such underwriting agreement shall contain such representations and warranties by the Company and such other terms and provisions as are customarily contained in agreements of this type, including, without limitation, indemnities to the effect and to the extent provided in Section 6. In connection with an underwritten public offering pursuant to this Section 12, the Company shall (i) cooperate with the selling holders of Registrable Securities, the underwriters participating in the offering and their counsel in any due diligence investigation reasonably requested by the selling holders or the underwriters in connection therewith, (ii) obtain customary opinions and “cold comfort” letters and (iii) participate, to the extent reasonably requested by the managing underwriter for the offering or the selling holder, in efforts to sell the Registrable Securities under the offering (including, without limitation, participating in “roadshow” meetings with prospective investors upon reasonable notice to the Company and at mutually agreed-upon times and locations among the Company, the managing underwriter and the Purchasers) that would be customary for underwritten primary offerings of a comparable amount of equity securities by the Company.

- 12 -

13. MISCELLANEOUS.

A. A person or entity is deemed to be a holder of Registrable Securities whenever such person or entity owns of record such Registrable Securities. If the Company receives conflicting instructions, notices or elections from two or more persons or entities with respect to the same Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from the registered owner of such Registrable Securities.

B. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (i) upon delivery to the party to be notified, (ii) when received by email or confirmed facsimile, or (iii) one (1) business day after deposit with a nationally recognized overnight carrier, specifying next business day delivery, with written verification of receipt.

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 the 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 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 the 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 Agent 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 Agent 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 the 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 the 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 the First-Lien Agent 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 Agent 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 Agent 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 the First-Lien Agent, being perfected.

(b) The First-Lien Agent 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 Agent and the Second-Lien Agent further acknowledge and agree that, in the event that the 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 the 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 the First-Lien Agent, the Parent or applicable Grantor shall grant to the Second-Lien Agent a Lien on such Non-Collateral Asset and cooperate with the Second-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 and to be subordinate to the Lien in such Collateral in favor of the First-Lien Agent 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 the 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 Agent (to be applied by First-Lien Agent 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 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, 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 Agent as an attorney-in-fact for such holder of Second-Lien Obligations, to so file any such Proof of Claim; provided, that First-Lien Agent shall have no obligation to make any such filings. In the event the 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 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 the First-Lien Agent or any other First-Lien Creditor or any other exercise

by the 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 the 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) the First-Lien Agent 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 Agent 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 Agent 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 Agent 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 the 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 the 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, the 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 Agent 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 Agent shall deliver to the Second-Lien Agent any proceeds of Collateral held by it 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 the 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. The 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 Agent’s 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 the 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 the 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 Agent or such Grantor such termination statements,

releases and other documents as the First-Lien Agent 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 Agent and any officer or agent of the 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 Agent (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 Agent 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 Agent 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 the 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 Agent, 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 Agent):

“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 Subordination Agreement, dated as of October __, 2013 (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, ▇▇▇▇▇▇ Ventures III LP, in its capacity as the initial First-Lien Agent, 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 5.03(a), each Grantor, the First-Lien Agent (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 Agent, 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 Agent 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 Refinanced or entered into to the extent such amendment, supplement, restatement, modification or Refinancing, or the terms of any new First-Lien Credit Documents, amends or modifies 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.

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) 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, each hereby appoint ▇▇▇▇▇▇ Ventures III LP as its collateral agent (in such capacity, together with any successor in such capacity from time to time, the “Control Agent”) 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. The 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, 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) each hereby agrees that the 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 Agent and the First-Lien Creditors, the duties or responsibilities of the First-Lien Agent 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 Agent (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 Agent and the Second-Lien Agent and (ii) delivering such collateral as set forth in Section 5.5(e).

(d) Neither the Control Agent nor the 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 Agent 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 Agent and the Second-Lien Agent, the Control Agent shall deliver to the First-Lien Collateral 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 the 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 the 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 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 the 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 Agent 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, 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 Agent) 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 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 the 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 the First-Lien Agent, or (ii) oppose any request by the 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 the 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 the First-Lien Agent or the other First-Lien Creditors to any motion, relief, action or proceeding based on the 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 the 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 the First-Lien Agent with respect to value); it being further understood that neither the 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 Agent 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 Agent, 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, the First-Lien Agent, on behalf of itself and the First-Lien Creditors under the 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 Agent 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. The First-Lien Agent, on behalf of itself and the First-Lien Creditors under the 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 Agent 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 Agent 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 Agent, 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 Agent 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 Agent 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 the 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 the 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 the First-Lien Agent, arising out of any and all actions which the Control Agent, the First-Lien Creditors or the First-Lien Agent 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 Agent 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 Agent 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 Agent 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 Agent 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 Agent 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 Agent 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 the 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 Collateral 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 Agent 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 Agent, 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.
