- 24 -

this Agreement; (ii) obtain from any Governmental Authorities and any third parties any actions, non-actions, clearances, waivers, consents, approvals, permits, orders, authorizations, registrations, qualifications, designations, declarations or filings required to be obtained by the Company, Purchaser or any of their respective Subsidiaries in connection with the authorization, execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby; (iii) subject to the cost allocation provisions set forth herein, make all registrations, filings, notifications or submissions which are necessary or advisable, and thereafter make any other required submissions, with respect to this Agreement and the transactions contemplated hereby required under (A) any applicable federal or state securities laws, (B) any applicable competition, antitrust or investment laws (including, if applicable, under the HSR Act), and (C) any other applicable law; and (iv) execute and deliver any additional instruments necessary to consummate the transactions contemplated by this Agreement.

6.17 Proxy Statement; Special Meeting. Solely in the event that the Company determines that such action is required to consummate the matters set forth herein, KiOR shall use its reasonable best efforts to file a Proxy Statement with the SEC with respect to a meeting of the stockholders seeking the Stockholder Approval, which shall include a recommendation of the Board of Directors that the stockholders approve such matters (unless the Board determines in good faith, after consultation with legal and financial advisors, that its fiduciary duties require it to withdraw its recommendation in respect of the matters that are the subject of the Stockholder Approval). KiOR shall use commercially reasonable efforts to hold a meeting of its stockholders to vote on such matters no more than 30 Business Days after the mailing of its Proxy Statement to stockholders, as such time may be extended by adjournments to obtain the requisite quorum for such meeting.

6.18 [Reserved].

6.19 [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 Purchaser if it beneficially owns ten percent (10%) or more of the sum of the Shares originally issued to Purchaser at the First Closing and any Shares to be purchased by Purchaser at the Second Closing as of the time of such offer or sale. 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.

(B) KiOR shall give notice (the “Offer Notice”) to 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.

(C) By notification to KiOR within (I) seven (7) days in the case of any New Securities comprised of equity securities, and (II) seventeen (17) days in the case of any New Securities comprised of debt securities, after the Offer Notice is given, Purchaser may elect to purchase or otherwise acquire, at the price and on the terms specified in the Offer Notice, up to its Pro Rata portion of such New Securities.

(D) If 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

- 25 -

of the New Securities described in the Offer Notice with respect to which Purchaser 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 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 Purchaser in the manner provided in this Section 6.20.

6.21 [Reserved].

6.22 Delivery of Share Certificate. Within two business days following the First Closing, the Option Closing and the Second Closing, as applicable, the Company shall deliver to Purchaser a certificate for the number of Shares set forth opposite Purchaser’s name under the heading “First Closing” on Exhibit A or that are purchased at the Option Closing or “Second Closing”, as the case may be, registered in the name of Purchaser.

ARTICLE 7

RESTRICTIONS ON TRANSFERABILITY OF SHARES

7.1 Restrictions on Transferability.

(A) The Shares shall not be sold, transferred assigned or hypothecated by Purchaser prior to the Release Date; provided that transfer of such shares in connection with a Change in Control or to (i) a member of such limited liability company, (ii) an entity that controls, or is controlled by, or is under common control with such limited liability company, or (iii) the estate of any such member (collectively, clauses (i) through (iii) the “Permitted Transferees”) during the period ending on the Release Date shall be permitted (it being understood and agreed that the ▇▇▇▇ & ▇▇▇▇▇▇▇ ▇▇▇▇▇ Foundation and the ▇▇▇▇ & ▇▇▇▇▇▇▇ ▇▇▇▇▇ Foundation Trust are Permitted Transferees); provided, further, that in each of the foregoing cases (other than a Change of Control) the proposed transferee of the Shares 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 the Shares shall not be sold, transferred, assigned or hypothecated unless (i) there is an effective registration statement under the Securities Act covering such Shares, (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 Shares 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. Notwithstanding the provisions of the preceding sentence, no registration statement or opinion of counsel shall be required for any transfer of any Shares by a Purchaser to a Permitted Transferee; provided, that the proposed transferee of the Shares held by Purchaser agrees in writing to take and hold such Shares 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 Shares 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” and to have made each representation of a Purchaser under this Agreement and the other Transaction Documents.

(B) Any transfer not made in compliance with the requirements of this Section 7.1 shall be null and void ab initio, shall not be recorded on the books of KiOR or its transfer agent and shall not be recognized by KiOR. Purchaser acknowledges and agrees that any breach of this Section 7.1 by Purchaser would result in substantial harm to KiOR and its stockholders for which monetary damages

- 26 -

alone could not adequately compensate. Therefore, 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 Shares not made in compliance with this Section 7.1).

7.2 Restrictive Legends. Each certificate representing the Shares, and any other securities issued in respect of the Shares 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.

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.

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.”

7.3 Removal of Legend and Transfer Restrictions. The first paragraph of the foregoing legend shall be removed from the certificates representing any Shares, at the request of the holder thereof, (i) while a registration statement covering the resale of such Shares is effective under the Securities Act of 1933, as amended, (ii) following any sale of such Shares pursuant to Rule 144 (assuming the transferor is not an Affiliate of the Company), (iii) if such Shares 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 Shares 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 Shares 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 Purchaser to KiOR or the transfer agent (with notice to KiOR) of a legended certificate representing such Shares (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 7.3, as directed by Purchaser, issue and deliver (via reputable overnight courier) to Purchaser, a certificate representing such Shares that is free from all restrictive and other legends, registered in the name of Purchaser or its designee. KiOR shall be responsible for any fees with respect to any issuance of Shares or the removal of any legends with respect to any Shares in accordance herewith.

No omission or delay by 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 Purchaser is entitled, nor shall it in any way affect the right of Purchaser to enforce such provisions thereafter.

8.6 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.

8.11 Further Assurances. Each party agrees to cooperate fully with the other parties and to execute such further instruments, documents and agreements and to give such further written assurance as may be reasonably requested by any other party to evidence and reflect the transactions described herein and contemplated hereby and to carry into effect the intents and purposes of this Agreement.

- 29 -

8.12 Use of Purchaser Name.

8.13 Relationship with Purchaser. Nothing in this Agreement and no action of Purchaser pursuant to the Transaction Documents or otherwise shall be deemed to constitute Purchaser to be a partner, associate or joint venturer of the Company, nor to constitute control of the Company.

Registration Rights Agreement

KIOR, INC.

REGISTRATION RIGHTS AGREEMENT

This REGISTRATION RIGHTS AGREEMENT (this “Agreement”), dated as of October [ ], 2013, by and among KiOR, Inc., a corporation organized under the laws of the State of Delaware (the “Company”), and Gates Ventures, LLC, a limited liability company organized under the laws of the State of Washington (the “Purchaser”).

WHEREAS:

In connection with the Class A Common Stock Purchase Agreement, dated as of October 18, 2013, by and among the Company and the Purchaser (the “Purchase Agreement”), the Company has agreed, upon the terms and subject to the conditions contained therein, to issue and sell to the Purchaser (i) that number of shares of Class A Common Stock set forth opposite the Purchaser’s name under the heading “First Closing” on Exhibit A attached to the Purchase Agreement and (ii) subject to the consummation of a “Option Closing” or a “Second Closing” (each as defined in the Purchase Agreement), additional shares of Class A Common Stock for an aggregate amount set forth opposite the Purchaser’s name under the heading “Second Closing” on Exhibit A attached to the Purchase Agreement (which, together with the Class A Common Stock referred to in clause (i) of this paragraph, are referred to herein as the “Shares”).

To induce the Purchaser 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 Purchaser hereby agree as follows:

1. DEFINITIONS.

A. As used in this Agreement, the following terms shall have the following meanings:

i. “Class A Common Stock” means shares of the Company’s Class A Common Stock, $0.0001 par value per share.

ii. “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.

iii. “Note Purchase Agreement” means the Senior Secured Convertible Promissory Note Purchase Agreement, dated on or about the date hereof, by and among the Company and the parties thereto.

iv. “Note Registration Rights Agreement” means the Registration Rights Agreement, dated on or about the date hereof, by and among the Company and the parties thereto, entered into in conjunction with the Note Purchase Agreement.

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

vi. “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”).

vii. “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.

viii. “Registration Statement” means a registration statement of the Company under the Securities Act (including without limitation the Initial Registration Statement, the New Registration Statement and any Remainder Registration Statements, each, as defined below).

ix. “SEC Guidance” means (i) any publicly-available written or oral guidance, comments, requirements or requests of the SEC staff (ii) any written or oral guidance, requirements or requests by the SEC staff to the Company and (iii) the Securities Act.

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 the date that is six months after the date hereof (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 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

- 2 -

application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company shall promptly inform the Purchaser and use its commercially reasonable efforts to (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 Note Registrable Securities (as defined in the Note Registration Rights Agreement) are included in such offering, Registrable Securities (as defined in the Note Registration Rights Agreement) not acquired pursuant to the Note Purchase Agreement and (b) second by Registrable Securities that are Shares and, if Registrable Securities (as defined in the Note Registration Rights Agreement) are included in such offering, Note Registrable Securities (as defined in the Note Registration Rights Agreement) that are shares issued pursuant to the Note 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”).

B. ALTERNATIVE REGISTRATION.

i. Without limiting the obligations of the Company pursuant to Section 2(A) or any remedy available to the Purchaser for the breach thereof, if the Company cannot effect a registration pursuant to Section 2(A) hereof, and the Company receives a request from the Purchaser that the Company file a Registration Statement on Form S-1 with respect to at least fifty percent (50%) of the Registrable Securities, then the Company shall, as soon as practicable, and in any event within seventy-five (75) days after the date such request is given, file a Registration Statement on Form S-1 under the Securities Act covering all Registrable Securities that the Purchaser has requested to be registered. If the Purchaser intends to distribute the Registrable Securities covered by its request by means of an underwriting, the right of the Purchaser to include its Registrable Securities in such registration shall be conditioned upon the Purchaser’s participation in such underwriting and the inclusion of such Registrable Securities in the underwriting to the extent provided herein. In the event the Purchaser intends to distribute the Registrable Securities by means of an underwriting, and any Note Registrable Securities (as defined in the Note Registration Rights Agreement) are included in such underwriting, if the underwriters

- 3 -

advise the Purchaser 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 proportionally (as nearly as practicable) among the Purchaser and the other holders of Note Registrable Securities (as defined in the Note Registration Rights Agreement) requesting registration, based upon the total number of Registrable Securities and Note Registrable Securities (as defined in the Note Registration Rights Agreement) requested to be included in such underwriting. 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 Purchaser) 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 the Purchaser notice of such registration. Upon the request of the 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 the 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 the 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 Purchaser’s Registrable Securities in such underwriting unless the Purchaser accepts 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 discretion determine will not adversely impact the offering. Notwithstanding the foregoing, in no event shall the number of Registrable Securities and Note Registrable Securities (as defined in the Note 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 Purchaser pursuant to Section 2(C)(iv), then the Company will make payments to the Purchaser 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 Purchaser’s exclusive monetary remedy). In such event, the Company shall pay to the 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

- 4 -

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 Purchaser) required by the Purchaser in the Registration Statement with respect to information relating to the Purchaser, 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) in respect of the same Registrable Securities for the same period of time or (b) to the Purchaser in an aggregate amount that exceeds ten percent (10%) of the aggregate price paid by the 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.

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 the 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 Purchaser (it being agreed that any comments must be provided within such five (5) Trading Day or one (1) Trading Day period) and (ii) use commercially reasonable efforts to

- 5 -

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 the 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 the Purchaser, if the Purchaser’s 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 the Purchaser may reasonably request in order to facilitate the disposition of the Registrable Securities.

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 the Purchaser who holds Registrable Securities being 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 the Purchaser, for so long as the Purchaser 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 the Purchaser, if the Purchaser holds Registrable Securities covered by such prospectus, and, if requested, the Purchaser 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 Purchaser with revised prospectuses and, following receipt of the revised prospectuses, the Purchaser 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.

- 6 -

H. For so long as the Purchaser holds Registrable Securities, the Company shall cooperate with the Purchaser 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 Purchaser may reasonably request and registered in such names as the Purchaser may request.

I. For so long as the Purchaser holds Registrable Securities covered by a Registration Statement, at the reasonable request of the Purchaser, 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 the Purchaser proposes to sell its Registrable Securities in effecting a filing with FINRA pursuant to FINRA Rule 5110 as requested by the Purchaser and the Company shall pay the filing fee required for such filing within two (2) business days of the request therefor.

4. OBLIGATIONS OF THE PURCHASER. In connection with the registration of the Registrable Securities, the Purchaser 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 the Purchaser that the 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 the Purchaser of the information the Company requires from the Purchaser.

B. The Purchaser, by its 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 the Purchaser has notified the Company in writing of the Purchaser’s election to exclude all of the Purchaser’s Registrable Securities from such Registration Statement.

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

5. EXPENSES OF REGISTRATION. All reasonable expenses incurred by the Company or the Purchaser 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 Purchaser, shall be borne by the Company, excluding underwriting discounts, selling commissions and similar costs which shall be borne by the Purchaser.

- 7 -

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) the Purchaser, each of its (ii) directors, officers, partners, members, managers, stockholders, employees and agents, (iii) each person who controls the Purchaser 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 case of either such preliminary prospectus or final prospectus, 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 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 Purchaser 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 the Purchaser to comply with Section 4(C) or (C) the use by the 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 or delayed. 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 Purchaser pursuant to Section 10 hereof.

B. The Purchaser agrees 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

- 8 -

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 the Purchaser expressly for use in connection with such Registration Statement; and subject to Section 6(C) the 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 the 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 the Purchaser, which consent shall not be unreasonably withheld or delayed, 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 the 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 Purchaser 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 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 the Purchaser, if the Purchaser is 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.

- 9 -

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 Purchaser 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 Purchaser 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 Purchaser the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that may at any time permit the Purchaser to sell securities of the Company to the public, so long as the Registration Statement is effective and the 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 the Purchaser so long as the 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 Purchaser 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 Purchaser, (i) delay the filing of, or effectiveness of, a Registration Statement; or (ii) suspend such Registration Statement after effectiveness and require that the Purchaser 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 Purchaser a certificate signed by the Chairman

- 10 -

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 the Purchaser. If the Company requires the Purchaser 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 Purchaser 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 Purchaser given pursuant hereto, and the Purchaser 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 Suspensions, when taken together, to exceed thirty (30) days, in the aggregate, in any three (3) month period or seventy five (75) days, in the aggregate, in any twelve (12) month period.

10. ASSIGNMENT OF REGISTRATION RIGHTS. The rights of the Purchaser hereunder, including the right to have the Company register Registrable Securities pursuant to this Agreement, shall be automatically assignable by the 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 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 the Purchaser is transferred, only the Purchaser or only one Permitted Transferee designated by the Purchaser shall have the right to exercise rights hereunder on behalf of all holders of the 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 Purchaser. Any amendment or waiver effected in accordance with this Section 11 shall be binding upon the Purchaser and the Company.

12. UNDERWRITING. If at any time or from time to time during the effectiveness of a Registration Statement the Purchaser proposes to sell fifty percent (50%) or more of the Registrable Securities, the Purchaser 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 the Purchaser) and, in such event, (i) 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 Purchaser, and (ii) the Company shall promptly amend the Registration Statement to include any information reasonably requested to be included therein by the underwriters or Purchaser. Purchaser 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 Purchaser will be entitled to withdraw such request (such withdrawal to be effective only if made upon the failure to sell at least fifty percent (50%)

- 11 -

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 Purchaser) that would be customary for underwritten primary offerings of a comparable amount of equity securities by the Company.

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. All communications shall be sent to the Company and the Purchaser as follows or at such other addresses as the Company or the Purchaser may designate upon ten (10) days’ advance written notice to the other party:
