Exhibit 10.30

THIS STOCK PURCHASE AGREEMENT (this “Agreement”) is made and entered into on November 4, 2011 (the “Execution Date”) by and among BioAmber Inc., a Delaware corporation (the “Company”), and each of the other parties listed on Schedule I attached hereto (the parties listed on Schedule I are referred to herein as the “Purchasers” and each, a “Purchaser”).

RECITALS

WHEREAS, the Company’s Board of Directors has determined that in order to raise additional funds for the Company’s and its Subsidiaries general corporate purposes, potential asset or other acquisitions and certain other purposes, including an equity investment in the Sarnia plant the Company plans to build in 2012/13, it is in the best interest of the Company to issue 20,061 shares of the Company’s Common Stock, par value $0.01 per share (“Common Stock”), at a price of US$997.00 per share, on the terms and conditions set forth in this Agreement (the “Financing”); and

WHEREAS, the Company wishes to issue and sell to each Purchaser, and each Purchaser severally wishes to purchase from the Company, that number of shares of Common Stock as set forth on Schedule I attached hereto on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises, representations, warranties and covenants hereinafter set forth and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Agreement to Purchase and Sell Shares of Common Stock. At the Closing (as defined below), the Company shall sell and issue to each Purchaser participating in the Closing, and, subject to the terms and conditions set forth herein, each Purchaser participating in the Closing shall severally acquire and purchase from the Company, the number of Securities (as defined below) set forth on Schedule I attached hereto upon payment by each Purchaser of the purchase price for such Securities set forth on Schedule I attached hereto (the “Purchase Price”), payable as set out in Section 2 of this Agreement. The sale and purchase of the Securities to each Purchaser shall constitute a separate sale and purchase hereunder. The shares of Common Stock issued to the Purchasers are referred to in this Agreement as the “Securities.” On the Execution Date, the Purchasers and the Company will execute counterparts of this Agreement. Such executed counterparts to this Agreement will be held in trust by Person(s) designed by Purchasers until satisfaction of the conditions to Closing set forth in Section 6 of this Agreement. Given that the number of Securities that each Purchaser intends to acquire pursuant to this Agreement is not the number of shares that each Purchaser would be entitled to purchase pursuant to the Pre-emptive Rights (the “Pre-emptive Rights”) granted to them under Section 4 of the Amended and Restated Shareholders Agreement of the Company dated as of April 15, 2011 (the “Shareholders Agreement”), each Purchaser hereby waives its Pre-emptive Right in connection with the issuance of Securities by the Company under this Agreement.

2. Closing in Escrow; Deliveries; Payment; Release from Escrow. The closing in escrow of the purchase and sale of the Securities under this Agreement (the “Closing”) shall take place at 5pm New York City time on November 4, 2011 (the “Closing Date”), subject to the satisfaction (or waiver as provided herein) of the conditions set forth in Section 6 (other than those conditions that by their nature will be satisfied at the Closing), unless another time or date is agreed to in writing by the parties. This Agreement, the First Amendment to the Amended and Restated Shareholders Agreement of the Company attached hereto as Exhibit A (the “First Amendment”), and all other agreements, certificates, documents and instruments furnished in connection herewith or therewith at or prior to the Closing are referred to collectively herein as the “Closing Documents”. On the Escrow Release Time, subject to the terms and conditions hereof, the Company shall deliver to each Purchaser stock certificates evidencing the Securities to be purchased by such Purchaser dated as of the Closing, registered in such Purchaser’s name, upon payment of the Purchase Price therefor set forth opposite such Purchaser’s name on Schedule I by wire transfer of immediately available funds to such account as designated by the Company prior to the Closing Date or Escrow Release Time, as the case may be.

2.1 At the Closing, subject to the terms and conditions hereof, the Company shall deliver its counsel in escrow the following:

(a) a duly executed counterpart to the First Amendment;

(b) one or more duly executed stock certificates representing the Securities registered in the name of the Purchasers;

(d) a certificate of good standing as to each of the Subsidiaries issued by the Secretary of State, or similar governmental authority, in each such Subsidiaries’ jurisdiction of organization, dated as of a date within five (5) business days of the Closing Date;

(e) a certificate of the secretary of the Company in a form satisfactory to the Purchasers certifying as to (i) the incumbency of the officers executing the Closing Documents on behalf of the Company, (ii) the resolutions of the Board of Directors and, to the extent required under applicable law, the shareholders, of the Company duly authorizing the transactions contemplated by this Agreement and the other Closing Documents, and (iii) the Bylaws of the Company as in effect at the time of the Closing, and (iv) the Amended and Restated Certificate of Incorporation of the Company as in effect at the time of the Closing;

(f) a certificate of each of Xxxx-Xxxxxxxx Huc, Xxxxxxx Xxxxxxxx and Xxx Xxxxxx (the “Key Company Personnel”) pursuant to Section 6.5 hereof;

(g) copies of all consents, waivers and other approvals required in connection with execution, delivery and performance of this Agreement and the other Closing Documents and the other transactions contemplated hereunder and thereunder.

2.2 At the latest on the Escrow Release Time, subject to the terms and conditions hereof, the Purchasers shall deliver to the Company’s counsel, in escrow, wire transfers in the aggregate amount of the Purchase Price as described on Schedule I.

2.3 The Closing Documents shall be held in escrow by the Company’s counsel, until 5pm New York City time on November 11, 2011, unless another time or date is agreed to in writing by the parties (the “Escrow Release Time”).

2.4 On the Escrow Release Time, subject to each of the Purchasers having delivered its share of the Purchase Price to Company’s counsel in escrow, the Company’s counsel shall release the Closing Documents in its possession from escrow to their intended recipients and remit the share of the Purchase Price in its possession to the Company.

2.5 In the event that, at the Escrow Release Time, the Company’s counsel has not received all Purchasers’ share of the Purchase Price, described on Schedule I, the Company’s counsel shall so notify each of the Purchasers and request instructions in respect of Closing Documents and share of the Purchase Price in its possession. If so requested, the Company’s counsel shall forthwith return to a Purchaser its share of the Purchase Price and the Closing Documents received from such Purchaser.

3.3 Capitalization.

(a) The authorized capital stock of the Company consists of 500,000 shares of Common Stock, 267,618 shares of which are issued and outstanding. Schedule 3.3(a) sets forth a capitalization table of the Company on a post-closing, as-converted, fully-diluted basis.

Under the Plan, there are no shares reserved but not yet subject to options already granted and outstanding. All options granted pursuant to the Plan will vest upon an initial public offering of the Company’s shares or a sale/merger transaction involving the Company and some employees have, pursuant to their employment agreements, options that provide for accelerated vesting upon the death of the employee or the termination of their employment by the Company. Subject to the foregoing, no employee, officer, director or consultant has options or any other securities that provide for accelerated vesting upon termination of employment or service, merger or change of ownership of the Company or any other event.

The Closing of the transactions contemplated by this Agreement will not result in (i) accelerated vesting of any options or other equity-based compensation, or (ii) the payment or the obligation of the Company or any of its Subsidiaries to pay or accelerate the payment of any bonus or other compensation to any employee, consultant, officer, director, or advisor.

(d) Other than as set out in the Shareholders Agreement, the Company is not under any obligation, and has not granted any rights, to register any of the Company’s presently outstanding securities or any of its securities that may hereafter be issued. No stockholder of the Company has entered into any agreement with the Company or, to the Company’s knowledge, any other Person, with respect to the voting or transfer of equity securities of the Company, except for the Shareholders Agreement.

(e) All issued and outstanding shares of the Company’s capital stock (i) have been duly authorized and validly issued and are fully paid and nonassessable, and (ii) were issued in accordance with all applicable securities Laws, including, without limitation, the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), and applicable state securities Laws or pursuant to an exemption from such registration requirements.

(f) The Securities have been duly and validly reserved for issuance. When issued in compliance with the provisions of this Agreement, the Securities will be (i) validly issued, fully paid and nonassessable, (ii) issued in compliance with applicable federal and state securities Laws, and (iii) will be free of any mortgage, pledge, lien, conditional sale agreement, security agreement, encumbrance or other charge or restriction on transfer of title or voting, whether imposed by agreement, understanding, Law, equity or otherwise (collectively, “Liens”); provided, however, that the Securities may be subject to restrictions on transfer under applicable state and/or federal securities Laws and the provisions of the Shareholders Agreement.

(g) Schedule 3.3(g) sets forth a capitalization table of each of the Subsidiaries on an as-converted, fully-diluted basis. Such capitalization tables identify by name and number of securities owned, each holder of outstanding securities of the Subsidiaries. There are no outstanding options, warrants, rights (including conversion or preemptive rights, rights of first refusal and phantom stock rights), proxy, voting, transfer restriction or stockholder agreements, or agreements of any kind for the purchase or acquisition from any of the Subsidiaries of any of their securities. None of the Subsidiaries is under any obligation, nor has any of the Subsidiaries granted any rights, to register any of their presently outstanding securities or any of their securities that may hereafter be issued. All issued and outstanding shares of capital stock and other equity interests, as applicable, of each of the Subsidiaries have been duly authorized and validly issued and are fully paid and nonassessable and were issued in accordance with all applicable Laws.

3.4 Authorization; Binding Obligations. All corporate action on the part of the Company, its officers, directors and stockholders necessary for the authorization of this Agreement and the Closing Documents, the performance of all obligations of the Company hereunder and thereunder and the authorization, sale, issuance and delivery of the Securities has been taken. This Agreement and the other Closing Documents have been duly executed and delivered by the Company and constitute valid and binding obligations of the Company enforceable in accordance with their respective terms except (a) as limited by applicable

No proceeding charging the Company or any of its Subsidiaries with infringement of any Intellectual Property of any third Person has been filed or, to the Company’s knowledge, is threatened to be filed.

Neither the Company, any of its Subsidiaries nor any employee of the Company or any of its Subsidiaries is obligated under any duty or agreement (including any license, confidentiality agreement, covenant or commitment of any nature), or subject to any judgment, decree or order of any court or administrative agency, that would interfere in any manner with the use of their best efforts to promote the interests of the Company or its Subsidiaries or that would conflict with the business as now conducted or proposed to be conducted of the Company or any of its Subsidiaries. Each current employee, officer and consultant of the Company and its Subsidiaries has executed a proprietary information and assignment of inventions agreement. No employee or consultant is in violation of any proprietary information or assignment of inventions agreement, or in any such similar agreement, with any former employer or contractor, and the carrying on of the Company’s or its Subsidiaries’ businesses and the conduct of the Company’s and its Subsidiaries’ businesses as proposed will not conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, such agreements.

(h) As used in this Agreement, the term “Intellectual Property” means (i) inventions (whether or not patentable), trade secrets, technical data, databases, customer lists, designs, tools, methods, processes, technology, ideas, know how and other confidential or proprietary information and materials; (ii) trade marks and service marks (whether or not registered), applications for trade marks and service marks, trade names, logos, trade dress and other proprietary indicia and all goodwill associated therewith; (iii) documentation, advertising copy, marketing materials, specifications, mask works, drawings, graphics, databases, recordings and other works of authorship, whether or not protected by copyright; (iv) source code, object code, data and operating files, user manuals, documentation, flow charts, algorithms, compilers, development tools, maintenance records and other materials related to computer programs; (v) internet web-sites and domain names; and (vi) all forms of legal rights and protections that may be obtained for, or may pertain to, the Intellectual Property set forth in clauses (i) through (v) in any country of the world, including, without limitation, all letters patent, patent applications, provisional patents, design patents, PCT filings and other rights to inventions or designs, all registered and unregistered copyrights in both published and unpublished works, trade secret rights, mask works, moral rights or other literary property or

3.12 Litigation. There is no litigation, arbitration, mediation or proceeding or investigation (each an “Action” and collectively, “Actions”) pending or, to the knowledge of the Company, threatened against the Company or any of its Subsidiaries or affecting any of their properties or assets or against any officer, director, or key employee of the Company or any of its Subsidiaries in his or her capacity as an officer, director or employee of the Company or any its Subsidiaries, or which may call into question the validity or hinder the enforceability of this Agreement or any other Closing Document or the transactions contemplated hereby and thereby; nor has there occurred any event nor does there exist any condition on the basis of which any such Action might be properly instituted or commenced. There are no Actions pending or, to the Company’s knowledge, threatened relating to the prior employment of any of the Company’s or its Subsidiaries’ employees or consultants, such employees’ or consultants’ use in connection with the Company’s or its Subsidiaries’ business of any information, technology or techniques allegedly proprietary to any of such employees’ or consultants’ former employers, clients or other parties, or such employees’ or consultants’ obligations under any agreements with prior employers, clients or other parties. Neither the Company nor any of its Subsidiaries is a party or subject to the provisions of any order, writ, injunction, judgment or decree of any court or government agency or instrumentality. There is no Action by the Company or any of its Subsidiaries pending or threatened against others.

3.13 Tax Returns and Payments. The Company and each of its Subsidiaries have filed on a timely basis all tax returns and reports as required by any applicable Laws. Such tax returns and reports correctly and completely reflect the liability for taxes and all other information required to be reported thereon by the Company and its Subsidiaries. The Company and each of its Subsidiaries have paid all taxes and other assessments due to be paid before the Closing. The Company and each of its Subsidiaries have adequately provided for, in its books of account and related records, liability for all unpaid taxes, being current taxes not yet due and payable. Neither the Company nor any of its Subsidiaries have been advised that any of their federal, state or other returns have been or are being audited, or of any deficiency in assessment in its federal, state or other taxes. All taxes and other assessments and levies which the Company or any of its Subsidiaries are required to withhold or collect have been withheld and collected and have been paid over to the proper governmental authorities.

3.14 Employees.

(a) Neither the Company nor any of its Subsidiaries maintains or contributes to any employee benefit plan, pension plan, stock option, bonus or incentive plan, severance pay policy or agreement, deferred compensation agreement, or any similar plan or agreement (an “Employee Benefit Plan”) other than the Employee Benefit Plans identified in Schedule 3.14. No other corporation, trade, or business exists which would be treated together with the Company or any of its Subsidiaries as a single “employer” under the provisions of Section 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended (the “Code”). Each Employee Benefit Plan has been and is currently administered in compliance with its constituent documents and all reporting, disclosure and other requirements of the Employee

Retirement Income Security Act of 1974, as amended (“ERISA”), and the Code and any other Law applicable to such Employee Benefit Plan. There are no unfunded obligations of the Company or any of its Subsidiaries under any retirement, pension, profit-sharing, deferred compensation plan or similar program, and any employee contributions withheld from payroll have been timely and fully contributed to the appropriate Employee Benefit Plan as required under applicable Law. Neither the Company nor any of its Subsidiaries is required to make any payments or contributions to any Employee Benefit Plan pursuant to any collective bargaining agreement or any applicable labor relations Law. Neither the Company nor any of its Subsidiaries has ever maintained or contributed to any Employee Benefit Plan providing or promising any health or other nonpension benefits to terminated employees (other than continuation coverage, at the maximum applicable premium permitted to be charged by the Company, required under Section 4980B of the Code, or Section 601 of the ERISA).

(b) Schedule 3.14(b) sets forth a list of (a) all members of the management team of the Company and the Subsidiaries, together with each such person’s position, date of hiring, salary and any other compensation payable to such person (including, without limitation, compensation payable pursuant to bonus, deferred compensation or commission arrangements), and (b) each contract, commitment, arrangement, or understanding, whether oral or written, relating to the employment of, or the performance of services by, any employee, consultant, or independent contractor. Neither the Company nor any of its Subsidiaries is delinquent in payments to any of their employees for any wages, salaries, commissions, bonuses or other direct compensation for any services performed for them to the date hereof or amounts required to be reimbursed to such employees. The Company and each of its Subsidiaries are in compliance with all applicable Laws, agreements, orders, and consent decrees respecting labor, employment, immigration, fair employment practices, terms and conditions of employment, and wages and hours. Neither the Company nor any of its Subsidiaries has any collective bargaining agreements with any of their employees. There is no labor union organizing activity pending or, to the Company’s knowledge, threatened with respect to the Company or any of its Subsidiaries. There are no charges of employment discrimination or unfair labor practices or any strikes, slowdowns, stoppages of work, or any other concerted interference with normal operations, pending or, to the knowledge of the Company, threatened against or involving the Company or any of its Subsidiaries.

(c) No employee of the Company or any of its Subsidiaries, nor any consultant with whom the Company or any of its Subsidiaries has contracted, is in violation of any term of any employment contract, proprietary information agreement or any other agreement relating to the right of any such individual to be employed by, or to contract with, the Company or its Subsidiaries because of the nature of the business conducted by the Company or any of its Subsidiaries; and to the Company’s knowledge, the continued employment by the Company and its Subsidiaries of their present employees, and the performance of the contracts with their independent contractors, will not result in any such violation. Neither the Company nor any of its Subsidiaries has received any notice alleging that any such violation has occurred. Except as disclosed on Schedule 3.14(c), no employee of the Company or any of its Subsidiaries has been granted the right to continued employment by the Company or any of its Subsidiaries or to any material compensation following termination of employment with the Company or its Subsidiaries. To the Company’s knowledge, no officer, key employee or group of employees intends to terminate his, her or their employment with the Company or its Subsidiaries, nor does the Company or its Subsidiaries have a present intention to terminate the employment of any officer, key employee or group of employees.

(d) Each Employee Benefit Plan has been administered and operated in compliance with Section 409A of the Code and neither the Company nor any Subsidiary has any obligations to employees or other service providers with respect to any deferred compensation plan, agreement, method, or arrangement which might be subject to an excise tax under Section 409A of the Code.

3.15 Compliance with Laws; Authorizations.

(a) The Company and each of its Subsidiaries have complied with each, and are not in violation of, any law, statute, regulation, rule, ordinance or order (collectively, “Laws”) to which the Company or any of its Subsidiaries or their businesses, operations, employees, assets or properties are or have been subject, including but not limited to any Laws which apply to the manufacture, distribution and/or export of succinic acid, modified PBS and other related polymers and/or formulations thereof. No event has occurred or circumstances exist that (with or without the passage of time or the giving of notice) may result in a violation of, conflict with or failure on the part of the Company or any of its Subsidiaries to comply with, any Law. Neither the Company nor any of its Subsidiaries has received notice regarding any violation of, conflict with, or failure to comply with, any Law. The execution, delivery, and performance of this Agreement and the other Closing Documents by the Company, and the sale, issuance and delivery of the Securities pursuant hereto will not, with or without the passage of time or giving of notice, result in any such violation, or be in conflict with or constitute a default under any Law.

(b) The Company and each of its Subsidiaries owns, holds, possesses or lawfully uses in the operation of their respective business all franchises, licenses, permits and registrations (collectively, “Authorizations”) which are required or otherwise necessary for them to conduct their business as currently conducted or as proposed to be conducted or for the ownership and use of the assets owned or used by them in the conduct of their business, free and clear of all Liens. Such Authorizations are valid and in full force and effect and none of such Authorizations will be terminated or impaired or become terminable as a result of the transactions contemplated by this Agreement or the other Closing Documents. All Authorizations are listed in Schedule 3.15(b). No event has occurred or circumstances exist that (with or without the passage of time or the giving of notice) may result in a violation of, conflict with, failure on the part of the Company or any of its Subsidiaries to comply with the terms of, or the revocation, withdrawal, termination, cancellation, suspension or modification of any Authorization. Neither the Company nor any of its Subsidiaries has received notice regarding any violation of, conflict with, failure to comply with the terms of, or any revocation, withdrawal, termination, cancellation, suspension or modification of, any Authorization. Neither the Company nor any of its Subsidiaries is in default or has received notice of any claim of default, with respect to any Authorization.

For purposes of this Section 3.16, “Environmental Laws” means any law, regulation, or other applicable requirement relating to (i) releases or threatened release of Hazardous Substance; (ii) pollution or protection of employee health or safety, public health or the environment; or (iii) the manufacture, handling, transport, use, treatment, storage, or disposal of Hazardous Substances. The Company and each of its Subsidiaries have obtained, and are in compliance with, all Authorizations required by any Environmental Laws.

4.1 Requisite Power and Authority. Each Purchaser has all necessary power and authority to execute and deliver this Agreement and the other Closing Documents and to carry out their provisions. All action on each Purchaser’s part required for the execution and delivery of this Agreement and the other Closing Documents has been taken. Upon its execution

and delivery, this Agreement and the other Closing Documents will be valid and binding obligations of each Purchaser, enforceable in accordance with their respective terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other Laws of general application affecting enforcement of creditors’ rights, and (b) as limited by general principles of equity that restrict the availability of equitable remedies.

4.2 Investment Representations. Each Purchaser is purchasing the Securities for its own account and not with a view to the resale, distribution or other disposition thereof in violation of the registration requirements of U.S. securities laws. Each Purchaser is an “accredited investor” that meets one or more of the criteria in Rule 501(a) of Regulation D under the Securities Act and is authorized to consummate the purchase of the Securities. Purchaser acknowledges (a) that the offer and sale of the Securities have not been registered under the Securities Act or the securities Laws of any state or other jurisdiction (b) that the Securities are being offered and sold pursuant to an exemption from registration under the Securities Act provided by Section 4(2) of Securities Act, and exemptions under applicable state securities Laws; and (c) that the Securities will be “restricted securities” as defined in Rule 144(a)(3) under the Securities Act and cannot be disposed of unless they are subsequently registered under the Securities Act and any applicable state Laws or the Purchaser has furnished to the Company an opinion of counsel of recognized standing or other evidence reasonably satisfactory to the Company to the effect that the proposed transfer may be made without registration under the Securities Act and any applicable state securities Laws. The foregoing, however, does not limit or modify the representations and warranties of the Company in this Agreement or the right of the Purchaser to rely thereon. Purchaser understands and agrees that the Securities will bear a legend substantially similar to the legend set forth below in addition to any other legend that may be required by applicable Law or by the Company’s Organizational Documents, as the same may be amended from time to time, or by any agreement between the Company and Purchasers:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL SUCH SECURITIES ARE REGISTERED UNDER SUCH ACT, AND APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY IS OBTAINED TO THE EFFECT THAT SUCH REGISTRATIONS ARE NOT REQUIRED.

The Purchaser acknowledges and agrees that it is not purchasing Securities as a result of “general solicitation” or “general advertising”, as such terms are defined in Regulation D under the Securities Act.

If the Purchaser is acquiring any Securities as a fiduciary or agent for one or more investor accounts, it represents that it has full power to make the foregoing representations, warranties and agreements on behalf of each such account and that the foregoing representations, warranties and agreements are true and correct and will be binding upon each such account.

damages, and the parties expressly waive their right to obtain such damages in arbitration or in any other forum. In no event, even if any other portion of these provisions is held to be invalid or unenforceable, shall the arbitrators have power to make an award or impose a remedy that could not be made or imposed by a federal court deciding the matter in the same jurisdiction. The arbitrator shall determine the allocation of the costs and expenses of the arbitration, including the arbitrator’s fee and the parties’ attorneys’ fees and expenses, based upon the extent to which each party prevailed in the arbitration.

(iii) No discovery will be permitted in connection with the arbitration unless expressly authorized by the arbitration panel upon a showing of substantial need by the party seeking discovery.

(iv) All aspects of the arbitration shall be treated as confidential. Neither the parties nor the arbitrators may disclose the existence, content or results of the arbitration, except as necessary to comply with legal or regulatory requirements. Before making any such disclosure, a party shall give written notice to all other parties and shall afford such parties a reasonable opportunity to protect their interests.

(v) The arbitrators shall render a written decision stating specifically the reasons of the fact and law on which the decision is based.

(vi) The result of the arbitration will be binding on the parties, and judgment on the arbitrators’ award may be entered in any court having jurisdiction. Any party may contest the Arbitrators’ decision and seek to have the award vacated, modified or corrected in a court of competent jurisdiction based only on the grounds that: (i) the decision is not in conformity with The Federal Arbitration Act (9 USC Sections 10-11); or (ii) where the arbitrators’ findings of fact are not supported by substantial evidence; or (iii) the decision was based on an erroneous conclusion of law.

(e) Injunctive Relief. Notwithstanding anything to the contrary in this Agreement including the foregoing Dispute Resolution provisions, any party may seek injunctive relief, including specific performance, in a court of law or equity for matters arising out of or relating to this Agreement. For purposes of this Section only, the parties stipulate and agree to the sole and exclusive jurisdiction of the United States District Court for the Central District of California to consider and hear any request by a party seeking injunctive relief. In the event that the aforementioned United States District Court lacks jurisdiction or venue to hear such a request for injunctive relief, the parties stipulate and agree to the sole and exclusive jurisdiction of the California State Court, Los Angeles County, to consider and hear such a request for injunctive relief.

7.3 Survival; Indemnification of Purchaser.

(a) The representations, warranties, certifications, covenants and agreements made in this Agreement or any other Closing Document shall survive any investigation made by the Purchaser and the closing of the transactions contemplated hereby and thereby.

(b) The Company and each of the Key Company Personnel, jointly and severally, hereby agree to hold harmless and indemnify the Purchasers, the Purchasers’ direct and indirect subsidiaries, affiliated entities and corporations, and each of their partners, officers, directors, employees, stockholders, agents and representatives (collectively, referred to as the “Purchaser Indemnitees”) against any and all damages, liabilities, losses (including, without limitation, losses due to diminution in the value of the Securities), costs and expenses (including attorneys’ fees and expenses), whether or not arising out of third-party claims, based upon, or arising out of, or relating to: (i) any inaccuracy in, or any breach by the Company of, any representation, warranty, certification or other statement contained in this Agreement or any other Closing Document, or (ii) any breach of any covenant or agreement contained in this Agreement or any other Closing Document, or (iii), any tax imposed on the Company (A) with respect to a taxable period or portion thereof ending on or before the Closing Date, (B) as a transferee or successor, by contract or pursuant to any law, to the extent that the liability for such tax relates to transactions or events that occurred on or prior to prior to the Closing, and (C) as a result of the Company being, on or prior to the Closing, a member of an affiliated, combined, consolidated, unitary or similar group pursuant to section 1.1502-6 of the Treasury Regulations (or any other similar provision of state, local or foreign Law), including but not limited to any taxes associated with the spin-off the Company by Diversified Natural Products, Inc. (collectively, the “Indemnifiable Claims”).

(c) The Company shall reimburse, promptly following request therefor, all expenses incurred by a Purchaser Indemnitee in connection with any Indemnifiable Claim, including, without limitation, any threatened, pending or completed action, suit, arbitration, investigation or other proceeding arising out of, or relating to, any Indemnifiable Claim.

(d) The rights to indemnification set forth in this Section 7.3 are in addition to, and not in limitation of, all rights and remedies to which the Purchaser may have in equity, including the right to seek specific performance, rescission or restitution, none of which such rights or remedies shall be affected or diminished by this Section 7.3. All remedies, either under this Agreement or any other Closing Document, the Company’s Organizational Documents or otherwise afforded to any party, shall be cumulative and not alternative.

(e) Notwithstanding anything else contained herein, it is understood and agreed that the liability of any Key Company Personnel to the Purchaser Indemnitees pursuant to this Section 7.3 shall be limited to any shares of Common Stock of the Company currently owned by such Key Company Personnel (including any stock options and warrants which may be converted or exchanged into shares of Common Stock of the Company), together with any cash proceeds which result from the sale or exercise thereof, and such Key Company Personnel shall discharge such liability by the surrender of such securities and/or any proceeds which have been received from the sale or exercise thereof.

7.4 Consent to Amendments and Waivers. Except as otherwise expressly provided herein, the provisions of this Agreement may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the prior written consent of each of Naxos, FCPR Sofinnova Capital VI and Mitsui & Co., Ltd. (collectively, the “Majority Purchasers”). No other course of

dealing between the Company and the Purchasers or any delay in exercising any rights hereunder or under the Amended and Restated Certificate of Incorporation of the Company shall operate as a waiver of any rights of any Purchaser. Any amendment or waiver effected in accordance with this Section 7.4 shall be binding upon the Company and the Purchasers, and their respective successors and assigns.

7.5 Entire Agreement. This Agreement and the Closing Documents constitute the entire agreement among the parties relative to the specific subject matter hereof and thereof.

7.6 Notices. All notices and other communications provided for herein shall be dated and in writing and shall be deemed to have been duly given (i) on the date of delivery, if delivered by facsimile, receipt confirmed, (ii) on the following business day, if delivered by a reputable nationwide overnight courier service guaranteeing next business day delivery; provided that, notices and other communications sent from or delivered outside of the United States of America shall be sent by a reputable international express courier service and shall be deemed to have been duly given upon delivery to the recipient, and (iii) two business days after being sent by certified or registered mail, return receipt requested, postage prepaid; provided that, notices and other communications sent from or delivered outside of the United States of America by certified or registered mail, return receipt requested, postage prepaid shall be deemed to have been duly given upon delivery to the recipient, in each case, to the party to whom it is directed at the following address (or at such other address as any party hereto shall hereafter specify by notice in writing to the other parties hereto):

7.7 Severability. In the event one or more of the provisions of this Agreement should, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

7.8 Counterparts; Delivery by Facsimile of PDF. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or electronic transmission in pdf format to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or electronic transmission in pdf as a defense to the formation or enforceability of a contract and each such party forever waives any such defense.

7.9 Successors and Assigns. Neither the Company nor any Purchaser may assign its rights and obligations under this Agreement except upon consent of the Majority Purchasers (with respect to an assignment by the Company) or the Company (with respect to an assignment by any Purchaser, as applicable); provided that, the provisions of this Agreement that are for each Purchaser’s benefit as a purchaser or holder of Securities are also for the benefit of, and enforceable by, any subsequent holder of such Securities but only if a transfer to such holder of the Securities complies with all applicable provisions of the Shareholders Agreement. Subject to the immediately foregoing sentence, all covenants and agreements contained in this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and permitted assigns of the parties hereto whether so expressed or not. Notwithstanding the foregoing, this Agreement cannot be assigned to a new investor without the consent of the Majority Purchasers, unless such new investor is an affiliate of a Purchaser.

In addition, it is acknowledged by each of the Purchasers that no Purchaser has acted as an agent of any other Purchaser in connection with making its investment hereunder and that no Purchaser shall be acting as an agent of any other Purchaser in connection with monitoring its investment hereunder.
