The Product License shall be transferable solely in accordance with Section 12.7 and sublicensable solely in accordance with Section 2.2. For clarity, the Parties agree and acknowledge that the Product License does not include any right to make or have made Drug Substance or Product or to access or use the Pfenex Expression Technology, except that NT Pharma shall have the right to use information related to the Pfenex Expression Technology provided pursuant to Section 3.1(b) to the extent necessary for NT Pharma to deal with regulatory affairs and medical affairs, promote and market the Product, and perform its other obligations and exercise its other rights provided under this Agreement in the Territory. Upon the request by either Party, the Parties shall discuss in good faith the necessary amendments to this Agreement to expand the scope of the Product License to Product in bulk form and to the supply agreement and quality agreement referenced in

If NT Pharma intends to grant a candidate a sublicense with respect to a portion of the Product License that is related to the application or maintenance of the Regulatory Approval in a jurisdiction within the Territory, it shall serve Pfenex a 30-day prior notice setting out the identity of such sublicensee, and (a) if the contemplated sublicense is with respect to Regulatory Approval in Mainland China, NT Pharma shall not grant such sublicense without Pfenex’s prior written consent, which is not to be unreasonably withheld, delayed or conditioned, and (b) if the contemplated sublicense is with respect to any jurisdiction outside Mainland China, NT Pharma shall give due consideration to any objection that may be raised by Pfenex within 30 days, but NT Pharma shall have the right to make a final decision as to whether to grant the sublicense at issue except that if Pfenex raises an objection for reason that the contemplated sublicense is likely to render Pfenex not compliant with Applicable Law, in which situation NT Pharma shall not grant the sublicense without Pfenex’s prior written consent. For clarity, it is understood and agreed that NT Pharma may choose and use distributors in the Territory at its discretion, provided that (A) NT Pharma remains primarily responsible for the activities of any such distributors, (B) NT Pharma (or its Affiliate) (I) books sales of Product in each country in the Territory in accordance with NT Pharma’s ordinary course of business, and (II) remains primarily responsible for the marketing and promotion of Product in the Territory, which will be under the Existing Trademark or other trademarks Controlled by NT Pharma or its Affiliates, and (C) any distributor that is granted the right to apply for or maintain the Regulatory Approval in a jurisdiction of the Territory shall be subject to the restrictions on sublicensing in this Section 2.2.

NT Pharma acknowledges the validity of the Existing Trademark, and shall not challenge or assist others to challenge the Existing Trademark (except to the extent such restriction is expressly prohibited by Applicable Law) or the registration thereof or attempt to register any trademarks, marks or trade names confusingly similar to those of Pfenex.

Thereafter, NT Pharma shall have the right, but not the obligation, to Prosecute and Maintain such Patent in such jurisdiction in the Territory at its own cost and expense, if doing so does not, in Pfenex’s reasonable, good faith determination, cause a material adverse effect on Pfenex’s Intellectual Property rights covering products other than Product.

(a) Disclosures.

Pfenex may settle, compromise or consent to any judgment with respect to any Enforcement Action without the prior written consent of NT Pharma, on fifteen (15) Business Days’ notice to NT Pharma; provided, that if, prior to the expiration of such fifteen (15) Business Day period, NT Pharma determines, and advises Pfenex of such determination in writing, that a settlement, compromise or consent to judgment with respect to a Competing Product Enforcement Action would likely have a material adverse impact on NT Pharma in the Territory, then Pfenex shall not settle, compromise or consent to any judgment with respect to such Competing Product Enforcement Action without the prior written consent of NT Pharma (which consent shall not be unreasonably withheld, delayed or conditioned).

(c) If Pfenex does not institute a Competing Product Enforcement Action against the Infringing Activity involving the Pfenex Technology within one (1) month from the date of the Infringement Notice and Pfenex has not provided notice to NT Pharma specifying that (i) the initiation of such Competing Product Enforcement Action is likely to invalidate or narrow the claims of any Pfenex Patent and (ii) such invalidation or narrowing would likely have a material adverse impact on Pfenex or its Affiliates, or the Pfenex Technology, NT Pharma shall have the right, but not the obligation, at NT Pharma’s sole cost and expense, to bring the Competing Product Enforcement Action; provided that NT Pharma shall provide prompt written notice of any such Competing Product Enforcement Action to Pfenex, permit Pfenex (subject to the Common Interest Agreement) to review and comment on strategic decisions and material pleadings and communications regarding such Competing Product Enforcement Action and give reasonable consideration to any comments made by Pfenex in relation to such Competing Product Enforcement Action.

Each Party shall retain in confidence all Confidential Information of the other Party and (except as expressly provided herein) shall not use Confidential Information of such other Party for any purpose other than the purposes indicated herein and in connection with the performance of this Agreement or disclose such Confidential Information to a Third Party other than its Agents without the written consent of such other Party. Confidential Information shall not include information that: (i) is or becomes public knowledge (through no fault of the receiving Party or its Agents); (ii) is made lawfully available to the receiving Party, other than under an obligation of confidentiality, by a Third Party that, to the knowledge of the receiving Party, is under no duty of confidentiality to the disclosing Party; (iii) is already in the receiving Party’s possession at the time of receipt from the disclosing Party (and such prior possession can be reasonably demonstrated by competent evidence by the receiving Party) other than as a result of disclosure by a Third Party that, to the actual knowledge of the receiving Party, was under a duty of confidentiality to the disclosing Party with respect to such information; or (iv) is independently developed by the receiving Party or its Affiliates without the use of or reference to Confidential Information of the other Party (and such independent development can be reasonably demonstrated by competent evidence prepared by the receiving Party) (collectively, the “Confidentiality Exceptions”). Notwithstanding the foregoing, a receiving Party may use and disclose Confidential Information of the other Party (A) to the extent required by Applicable Law; provided, however, that if legally permissible, the receiving Party shall give the disclosing Party advance written notice as promptly as is practicable to permit it to seek a protective order or other similar order, at the disclosing Party’s sole cost, with respect to the disclosure of such Confidential Information, and, thereafter, the receiving Party shall disclose only the minimum Confidential Information that it is advised by counsel is required to be disclosed in order to comply; (B) to the extent such disclosure is reasonably necessary for the Prosecution and Maintenance of Patents (including applications therefor) in accordance with Section 6.3, complying with the terms of the Dow Technology Assignment Agreement and Dow Technology Licensing Agreement (provided that Pfenex shall provide NT Pharma with prior written notice of any such disclosure, including a copy of any such disclosure), prosecuting or defending litigation, conducting preclinical or clinical studies, or obtaining and maintaining regulatory approvals (including Regulatory Approvals); (C) in communication with consultants and advisors (including financial advisors, lawyers and accountants) on a need to know basis, in each case, under appropriate non-disclosure and non-use obligations substantially equivalent to those of this Agreement (provided that the disclosing Party shall be responsible for any breach of this Section 8.1 by those parties to which it discloses Confidential Information); or (D) to the extent mutually agreed to by the Parties in writing. Either Party shall have the right to disclose this Agreement to actual and potential licensees and collaborators with respect to Product, investors and acquirers of a majority of the business or assets of such Party related to this Agreement in connection with negotiations of definitive agreements, under reasonable conditions of confidentiality.

Section 8.2 Agents. Each of Pfenex and NT Pharma shall limit disclosure of the other Party’s Confidential Information to only those of their respective Affiliates, directors, managers, officers, employees and contractors (collectively “Agents”) who are concerned with the performance of this Agreement, have a legitimate need to know such Confidential Information in the performance of their duties and are bound by written obligations of non-disclosure and non-use at least as protective of the disclosing Party and its Confidential Information as the terms hereof. Each Party shall be responsible for any breach of Section 8.1 by its Agents and advisors (including financial advisors, lawyers and accountants) and shall take all reasonably necessary measures to restrain its Agents and advisors (including financial advisors, lawyers and accountants) from unauthorized disclosure or use of the Confidential Information.

Section 8.3 Restrictions on Sharing Information. Notwithstanding anything to the contrary, neither Party shall be obligated pursuant to this Agreement to provide, or grant access to, any information (a) that is Confidential Information it is prevented from disclosing to the other Party by an enforceable confidentiality agreement with a Third Party and that such Party used Commercially Reasonable Efforts to obtain the consent of such Third Party to provide or grant access to the other Party, (b) the disclosure of which would adversely affect the attorney-client privilege between such Party and its counsel, based upon the advice of such Party’s outside legal counsel, or (c) the disclosure of which is not permitted pursuant to any Applicable Law or requirement of a Governmental Authority; provided in each case where information was not provided or access was not granted as would otherwise be required under this Agreement, such Party shall inform the other Party of the reason it was not provided or granted and a description of the specific nature of the applicable information. Following the Effective Date and during the Term, in connection with entering into any material agreement (or material amendment thereof) with any Third Party related to the Business, each Party agrees to use Commercially Reasonable Efforts to negotiate with such Third Party to include provisions in such agreement (or such amendment) sufficient to allow the other Party to receive relevant Confidential Information of such Third Party.

This Agreement supersedes the Mutual Confidentiality Agreement between the Parties dated November 15, 2017 (the “Prior Agreement”) with respect to information disclosed thereunder. All information exchanged between the Parties under the Prior Agreement shall be deemed Confidential Information of the disclosing Party and shall be subject to the terms of Sections 8.1, 8.2 and 8.3.

Section 8.4 Taxes.

(a) The Parties agree that for U.S. federal income tax purposes they will treat the transaction under this Agreement, unless otherwise required by Applicable Law, as a collaboration agreement that does not constitute a partnership or a joint venture, and agree to not take (or cause any Person to take), any position on any Tax return or in the course of any audit, examination or other proceeding inconsistent with such treatment, unless otherwise required by Applicable Law and except upon a final determination of the applicable Taxing Authority.

(b) Any and all payments by or on account of any obligation of any Party under this Agreement shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of the applicable withholding Party) requires the deduction or withholding of any Tax from any such payment by any Party, then such Party shall be entitled to make

such deduction or withholding, any amount so deducted or withheld shall be deemed paid to the other Party that was entitled to the payment subject to withholding, such Party shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law, and if such Tax is an Indemnified Tax, then the sum payable by the applicable Assignee shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 8.4) the applicable recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made. Upon request by the other Party, such withholding Party shall deliver to the other Party that was entitled to the payment subject to withholding, the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the other Party.

(c) Any Assignee shall indemnify the Non-Assigning Party, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 8.4) payable or paid by such Non-Assigning Party or required to be withheld or deducted from a payment to such Non-Assigning Party and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. Notwithstanding anything to the contrary in this Agreement, if a Party (the “Taxed Party”) obtains a credit from any Governmental Authority for any portion of any Indemnified Tax paid by the other Party, then the Taxed Party shall promptly reimburse the other Party the amount of such credit, and the Taxed Party shall use Commercially Reasonable Efforts to obtain available credits with respect to any such Indemnified Taxes.

(d) All transfer, documentary, sales, use, excise, customs, charges, duties, ad valorem, value added, stamp, registration, recording, property and other such similar Taxes (other than, for the avoidance of doubt, Taxes assessed against income), and all conveyance fees, recording charges and other fees and charges (including any penalties and interest) lawfully assessed or charged in connection with any of the transactions contemplated under this Agreement (collectively, “Transfer Taxes”) shall be paid and borne by the paying Party when due, and the Party responsible under such Applicable Law for paying such Transfer Taxes shall, at its own expense, file all necessary Tax returns and other documentation with respect to all such Transfer Taxes, and, if required by Applicable Law, the Parties will, and will cause their Affiliates to, join in the execution of any such Tax returns and other documentation.

Section 8.5 Nonsolicitation. Each Party (for purposes of this Section 8.5, a “Soliciting Party”) agrees that, during the Term, such Soliciting Party will not solicit for employment or consultancy, employ or engage as a consultant or solicit the termination of employment or consultancy with the other Party (a “Solicitation Action”), any individual that at the time of such Solicitation Action (a) is an officer or employee of the other Party or a consultant that is devoting a majority of such individual’s time to the business of the other Party and (b) is or was actively involved in the other Party’s performance of its obligations hereunder; provided, however, that the foregoing shall not prohibit (i) any advertisement or general solicitation (or hiring or engagement as an employee or consultant as a result thereof) for employment or consultancy not specifically directed at any such individual; (ii) the hiring or engagement as an employee or consultant of any such individual who initiates employment

or consultancy discussions with such Soliciting Party, provided that such initial discussions are not encouraged or solicited by such Soliciting Party; or (iii) any Solicitation Action with respect to any individual following the cessation of such individual’s employment with (or service as a consultant that is devoting a majority of such person’s time to the business of) the other Party without any solicitation or encouragement by such Soliciting Party.

Section 8.6 Publications. NT Pharma may publish or present data or results relating to Product in scientific journals with primary circulation in the Territory or at scientific conferences in the Territory, subject to the prior review, comment and approval by Pfenex as set forth in this Section 8.6, such approval not to be unreasonably withheld, delayed or conditioned.

Pfenex shall have thirty (30) days (for publication in scientific journals) or ten (10) days (for presentation at scientific conferences) from its receipt of any such abstract, manuscript or presentation in which to notify NT Pharma in writing of its approval or any specific objections to the disclosure. In the event that Pfenex objects to the disclosure in writing within such thirty (30) or ten (10) day period, NT Pharma agrees not to submit the publication or abstract or make the presentation containing the objected-to information until the Parties have agreed to the content of the proposed disclosure, and if the Parties are unable to agree, the matter shall be referred to the Executive Steering Committee. NT Pharma shall delete from the proposed disclosure any Confidential Information of Pfenex upon the request of Pfenex. NT Pharma shall delay any proposed disclosure to allow Pfenex sufficient time for the drafting and filing of a patent application directed to any patentable subject matter identified by Pfenex in such proposed disclosure. Once any such abstract or manuscript is accepted for publication, NT Pharma shall provide Pfenex with a copy of the final version of the manuscript or abstract. The Parties further agree that for the presentation at scientific conferences, if the abstract, manuscript or presentation intended for a forthcoming scientific conference does not go beyond that previously approved by Pfenex, then it shall be exempted from further approval by Pfenex as provided under this paragraph.

Section 11.2 Indemnification by NT Pharma. NT Pharma shall Indemnify Pfenex, its Affiliates and its and their respective directors, officers, employees, agents and representatives (the “Pfenex Indemnitees”) from and against any and all Losses resulting from Third Party Claims against any Pfenex Indemnitee arising out of (i) any breach by NT Pharma of any of its obligations or representations and warranties or covenants hereunder, (ii) the negligence, recklessness or willful misconduct by NT Pharma or any of its Affiliates or any of their respective officers, directors, employees, agents or representatives in connection with the performance of this Agreement, (iii) any violation by NT Pharma or any of its Affiliates and any of their respective officers, directors, employees, agents or

Section 11.3 Indemnification Procedure.

(a) The Party seeking indemnification under this Article XI (the “Indemnified Party”) agrees to give prompt written notice (the “Indemnification Notice”) to the Party against whom indemnity is sought (the “Indemnifying Party”) of the assertion of any Third Party Claim, or the commencement of any proceeding in respect of which indemnity may be sought under this Article XI; provided that the failure of an Indemnified Party to promptly notify the Indemnifying Party on a timely basis will not relieve the Indemnifying Party of any liability that it may have to the Indemnified Party unless and to the extent the Indemnifying Party demonstrates that it is materially prejudiced by the Indemnified Party’s failure to give timely notice.

(b) If the Indemnifying Party does not object to any claim or claims made in the Indemnification Notice in a written objection (the “Indemnification Objection”) prior to the expiration of twenty (20) Business Days from the Indemnifying Party’s receipt of the Indemnification Notice, the Indemnifying Party shall be deemed not to object to the information contained within the Indemnification Notice. If the Indemnifying Party delivers an Indemnification Objection within such twenty (20) Business Day period, the Indemnifying Party and the Indemnified Party shall attempt in good faith to resolve the dispute for twenty (20) Business Days after the Indemnifying Party’s receipt of such Indemnification Objection. If no resolution is reached, the dispute shall be resolved in accordance with the provisions of Section 12.4 and Section 12.5.

(c) The Indemnifying Party, if it so elects, may assume and control the defense of a Third Party Claim at the Indemnifying Party’s expense and shall consult with the Indemnified Party with respect thereto, including the employment of counsel reasonably satisfactory to the Indemnified Party; provided, however, that the Indemnifying Party shall not have the right to assume control of such defense if the claim that the Indemnifying Party seeks to assume control of (i) seeks material non-monetary relief or (ii) involves criminal or quasi-criminal allegations. If the Indemnifying Party is permitted to assume and control the defense of a Third Party Claim and elects to do so, the Indemnified Party shall have the right to employ counsel separate from counsel employed by the Indemnifying Party in any such action and to participate in the defense thereof, but the fees and expenses of such counsel employed by the Indemnified Party shall be at the expense of the Indemnified Party unless (x) the Indemnifying Party has specifically agreed in writing otherwise, (y) the Indemnified Party has been advised by outside counsel that a reasonable likelihood exists of a material legal conflict of interest between the Indemnifying Party and the Indemnified Party or (z) the Indemnifying Party has failed to assume the defense and employ counsel (in which case the fees and expenses of the Indemnified Party’s counsel shall be paid by the Indemnifying Party if the Indemnifying Party otherwise has an obligation to indemnify the Indemnified Party for the related Third Party Claim). If the Indemnifying Party has assumed the defense of a Third Party Claim in accordance with the terms hereof, the Indemnifying Party may not enter into a settlement

or consent to any judgment without the prior written consent of the Indemnified Party unless (A) such settlement or judgment involves monetary damages only, all of which will be paid, without limitation, by the Indemnifying Party, and no admission of fault or culpability on behalf of any Indemnified Party, and (B) a term of the settlement or judgment is that the Person or Persons asserting such claim unconditionally and irrevocably release all Indemnified Parties from all liability with respect to such claim; otherwise, the consent of the Indemnified Party shall be required in order to enter into any settlement of, or consent to the entry of a judgment with respect to, any claim (which consent shall not be unreasonably withhold, delayed or conditioned). If the Indemnifying Party does not assume or is not controlling the defense of a Third Party Claim for any reason, then the Indemnified Party may retain counsel of its own choosing, at the expense of the Indemnifying Party, and assume and control the defense of such Third Party Claim, and the Indemnifying Party shall have the right to employ counsel separate from counsel employed by the Indemnified Party in any such action and to participate in the defense thereof, but the fees and expenses of such counsel employed by the Indemnifying Party shall be at the expense of the Indemnifying Party. The Indemnifying Party shall have no obligations with respect to any Losses resulting from the Indemnified Party’s admission, settlement or other communication without the prior written consent of the Indemnifying Party (which shall not be unreasonably withheld, delayed or conditioned).

Section 11.4 Limitations on Liability. EXCEPT AS ARISING AS THE RESULT OF THE FRAUD OR WILLFUL MISCONDUCT BY A PARTY, OR ARISING FROM BREACH OF A PARTY’S CONFIDENTIALITY OBLIGATIONS IN SECTIONS 8.1-8.3 OR OBLIGATIONS UNDER SECTION 3.7 AND EXCEPT WITH RESPECT TO OBLIGATIONS TO INDEMNIFY A PARTY UNDER SECTION 11.1 OR SECTION 11.2, NEITHER PARTY, NOR ANY OF THEIR RESPECTIVE AFFILIATES, DIRECTORS, MEMBERS, OFFICERS, EMPLOYEES, SUBCONTRACTORS OR AGENTS, SHALL HAVE, UNDER ANY LEGAL THEORY (INCLUDING CONTRACT, NEGLIGENCE AND TORT LIABILITY), ANY LIABILITY TO ANY OTHER PARTY FOR ANY CONSEQUENTIAL, SPECIAL, INDIRECT, INCIDENTAL OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO BREACH OF THIS AGREEMENT.

Section 11.5 Unavailability of Indemnification. If the indemnification provided for in this Article XI is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any Loss, then the Indemnifying Party shall, in lieu of indemnifying such Indemnified Party hereunder, contribute to the amount paid or payable by such Indemnified Party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of, and relative benefit enjoyed by, the Indemnifying Party, on the one hand, and the relative fault of, and relative benefit enjoyed by, the Indemnified Party, on the other hand, in connection with the actions or omissions that resulted in such Loss as well as any other relevant equitable considerations.

ARTICLE XII.

MISCELLANEOUS

Section 12.1 Force Majeure. Neither Party shall be held liable or responsible to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from the causes beyond the reasonable control of the affected Party, including: fire, floods, earthquake, tsunami, ice, tornado, hurricane, windstorm, eruption, explosion, sabotage or vandalism, embargoes, war, acts of war (whether war be declared or

not), invasion, domestic or foreign terrorist act, act of a public enemy, insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, shortages of materials, failure of utilities, acts of God or acts, omissions or delays in acting by any Governmental Authority (each, an event of “Force Majeure”); provided that such affected Party shall provide the other Party with prompt written notice of the circumstances surrounding such a material failure or delay and will use Commercially Reasonable Efforts to overcome the difficulties created thereby and to resume performance of its obligations as soon as practicable. If the performance of any such obligation under this Agreement is delayed owing to such a Force Majeure for any continuous period of more than one hundred eighty (180) days, the Parties will consult with respect to an equitable solution, including the possibility of the mutual termination of this Agreement. For the avoidance of doubt, the occurrence of an event of Force Majeure shall not relieve any Party from fulfilling any obligation required hereunder; rather, the period for performance of such obligation shall be tolled during the occurrence of such Force Majeure.

Section 12.2 Notices. Any notice, request, approval or consent required or permitted to be given by any Party shall be in writing and shall be to the Parties at the addresses or facsimile number listed below, or such other address or facsimile number as such Party will have last given by notice to the other Party, and shall be deemed to have been sufficiently given when delivered in person, transmitted by facsimile (receipt verified) or by express courier service (signature required) or five (5) days after it was sent by registered mail, return receipt requested (or its equivalent), provided that no postal strike or other disruption is then in effect or comes into effect within two (2) days after such mailing.
