such additional information in its possession, as the case may be. Following the mutual agreement of the Parties with respect to the achievement of Successful Expression for each HemOnc Product, Pfenex shall provide Jazz with the amount of such HemOnc Product set forth in Exhibit 1.143 meeting the specifications as described in Exhibit 1.143 (with respect to each HemOnc Product, the “ Assessment Materials ”). The data contained in the Expression Feasibility Data Package shall be the Confidential Information of Jazz, and Jazz shall have all right, title, and interest in and to the data contained in the Expression Feasibility Data Package and the Assessment Materials. Notwithstanding anything to the contrary in this Agreement, as between the Parties, Pfenex shall retain all right, title and interest in and to any Pfenex IP (including any Information disclosed by Pfenex to Jazz in connection with such Assessment Materials or otherwise under this Agreement) and all Pfenex Improvements assigned to Pfenex pursuant to Section 7.1(c).

If Jazz provides Pfenex with a Declination Notice for a HemOnc Product, then Jazz shall be deemed to have terminated this Agreement with respect to such HemOnc Product pursuant to Section 11.2, and such termination shall be deemed to be effective as of the date of receipt of notice. If Jazz does not provide Pfenex with a Declination Notice during the Assessment Period with respect to either HemOnc Product, Jazz will retain its license hereunder and be obligated to commence its obligations with respect to such HemOnc Product, and such HemOnc Product will remain a Product for the purposes of this Agreement.

(b)      License to Jazz . Pfenex hereby grants Jazz an exclusive (even as to Pfenex except as provided in Section 2.1(c) below), royalty-bearing and sublicenseable (subject to Section 2.1(d)) license, under the Pfenex IP to research, Develop, make, have made, use, sell, have sold, offer for sale, import, and otherwise Commercialize the HemOnc Products in the Field in the Territory.

2.4    Option for Pegaspargase Product.

(a)      Option Grant. Pfenex hereby grants Jazz an exclusive option (the “ Option ”) to obtain an exclusive, sublicenseable (through multiple tiers) license from Pfenex under the Pfenex Pegaspargase Product IP to Develop, make, have made, use, sell, have sold, offer for sale and import and otherwise Commercialize the Pegaspargase Product in the Field in the Territory, subject to payment of such amounts as may be agreed in any Option Exercise Agreement. The foregoing license shall permit Pfenex to retain the right to perform any Development or manufacturing activities that the Parties agree to allocate to Pfenex in the Option Exercise Agreement.

(b)      Development of Pegaspargase Product . Pfenex shall Develop the Pegaspargase Product only in accordance with the mutually agreed Development Plan for such Product and with a primary objective for the Pegaspargase Product to have enzyme activity comparable to that of Oncaspar ^® . Pfenex shall keep Jazz informed of its Development of the Pegaspargase Product through the JDC or more frequently upon Jazz’s reasonable request, including the timeline, data and results of such Development activities. Pfenex shall notify Jazz through the JDC if Pfenex proposes to amend the then-current Development Plan for the Pegaspargase Product. Promptly following completion of the corresponding activities under the Development Plan for the Pegaspargase Product, Pfenex shall provide Jazz with Option Data Package 1 and, if Jazz has not previously delivered to Pfenex an Option Exercise Notice or if Jazz delivered an Option Exercise Notice but the Parties were unable to negotiate and enter into an Option Exercise Agreement pursuant to Section 2.4(d), Option Data Package 2. Pfenex shall, within ten (10) Business Days following Jazz’s written request, provide Jazz with any additional information reasonably requested by Jazz with respect to Option Data Package 1 or Option Data Package 2, as applicable (provided that such additional information is in Pfenex’s possession and does not require the expenditure of additional funds or the performance of additional studies to

16.

generate), or Pfenex shall notify Jazz in writing during such period that Pfenex does not have such additional information in its possession, as the case may be.

(c)      Option Exercise . Jazz may exercise the Option by providing written notice (an “ Option Exercise Notice ”) to Pfenex either:

(i)     during the twenty-five (25) Business Day period commencing upon Jazz’s receipt of Option Data Package 1; or

(ii)     to the extent that an Option Exercise Notice has not previously been delivered by Jazz to Pfenex in connection with Option Data Package 1 or if Jazz delivered an Option Exercise Notice but the Parties were unable to negotiate and enter into an Option Exercise Agreement pursuant to Section 2.4(d), during the twenty-five (25) Business Day period commencing upon Jazz’s receipt of Option Data Package 2.

If Jazz does not provide an Option Exercise Notice before the expiration of the period referenced in subsection (ii) above, then the Option shall lapse for the Pegaspargase Product and this Agreement shall be deemed terminated with respect to the Pegaspargase Product, and Pfenex may decide, in its sole discretion, whether to terminate or continue the Development and Commercialization of the Pegaspargase Product, itself or in collaboration with one or more Third Parties, and the terms of Section 2.6(c)(iii) shall apply with respect to such Product.

(d)      Negotiation . Following Jazz’s delivery of an Option Exercise Notice, the Parties shall use good faith efforts to negotiate the terms and conditions of a definitive agreement regarding the Pegaspargase Product (an “ Option Exercise Agreement ”) on an exclusive basis, meaning that Pfenex and its representatives shall not engage in discussions with any Third Party regarding a potential grant of rights to such Third Party with respect to the Pegaspargase Product during the negotiation period. The terms of such Option Exercise Agreement shall be commercially reasonable and all applicable non-financial terms and conditions shall be substantially the same as those in this Agreement, including decision-making, diligence, exclusivity (as applicable to the Pegaspargase Product), development, commercialization, manufacture, rights and obligations of the Parties, risk-allocation, intellectual property-related matters, dispute resolution, and general agreement structure, but excluding any rights of first negotiation or other rights except solely with respect to the Pegaspargase Product. Notwithstanding the foregoing, under the Option Exercise Agreement, Pfenex may opt-in to contribute to the Development costs of the Pegaspargase Product, and upon such opt-in, shall be responsible for between [***] and [***] of the Development costs in Pfenex’s discretion. The Option Exercise Agreement will also set forth usual and customary economic terms similar to those of this Agreement, including an upfront payment, clinical developmental and commercial milestone payments, and royalty payments, which payments shall take into account Pfenex’s level of contribution to the Development costs of the Pegaspargase Product. Without limiting the foregoing, the economic terms of the Option Exercise Agreement will reflect the level of development or commercial funding and risk assumed by each Party (taking into account Pfenex’s investment and risk prior to the Option Exercise Notice) and include the period over which royalties would be paid, as well as applicable deductions from royalty payments based upon royalty stacking for third party intellectual property (substantially the same as Section 6.5(c) herein) and generic competition.

With respect to the arbitration process, the Parties shall work with the arbitrator, who will determine a reasonable framework for resolving the issues in dispute between the Parties. This framework shall address a means to evaluate the overall economic value proposed by each party, the relative investments and risks assumed by each Party, the underlying assumptions in valuation models and the time-weighted allocation of overall economic value through the combination of milestone and royalty payments.

2.5      ROFN Products .

(a)      ROFN . With respect to each ROFN Product, Pfenex hereby grants Jazz an exclusive right of first negotiation (the “ ROFN ”) to obtain an exclusive, sublicenseable (through multiple tiers) license from Pfenex under the Pfenex ROFN Product IP for such ROFN Product to Develop, make, have made, use, sell, have sold, offer for sale and import and otherwise Commercialize such ROFN Product in the Field in the Territory under a definitive agreement as negotiated by the Parties pursuant to Section 2.5(c) for such ROFN Product.

(c)    Negotiation. Following Jazz’s delivery of a ROFN Exercise Notice for a particular ROFN Product, the Parties shall use good faith efforts to negotiate the terms and conditions of a definitive agreement regarding the ROFN Product (a “ ROFN Exercise

If the Parties are unable to reach agreement upon and do not enter into a mutually acceptable ROFN Exercise Agreement within three (3) months from Jazz’s delivery of the applicable ROFN Exercise Notice, then the Parties shall refer the matter for at least one in-person meeting (or telephone call if an in-person meeting is impractical) between the Parties’ respective Executive Officers.

(i)     With respect to any ROFN Product [***] (in each case, prior to the effect of any Half-Life Extension Component) (a “[***] ROFN Product ”), if the Parties are unable to reach mutual agreement on the terms of the ROFN Exercise Agreement within the three (3)-month period, Jazz may have the terms of the ROFN Exercise Agreement determined by baseball arbitration in accordance with Section 12.2(b), and the Parties shall promptly execute the ROFN Exercise Agreement on terms and conditions decided by such arbitration; provided that Jazz initiates such arbitration within sixty (60) days after such three (3)-month negotiation period. The arbitrator shall determine the terms and conditions of such ROFN Exercise Agreement generally taking into consideration the factors described in Section 2.4(d) for the Option Exercise Agreement.

(ii)     With respect to any ROFN Product [***] (in each case, prior to the effect of any Half-Life Extension Component) (a “[***] ROFN Product ”), if the Parties are unable to reach mutual agreement on the terms of the ROFN Exercise Agreement within the three (3)-month period, then the ROFN shall lapse for such [***] ROFN Product, and Pfenex may decide, in its sole discretion, whether to terminate or continue the development and commercialization of such [***] ROFN Product, itself or in collaboration with one or more Third Parties; provided that Pfenex shall notify Jazz within thirty (30) days after a Third Party first communicates in writing to Pfenex the general terms applicable to the development and commercialization of (or granting an option to develop and commercialize) such [***] ROFN Product as contained in a term sheet or proposed definitive agreement, [***]. Jazz further acknowledges and agrees that Pfenex has no obligation to conduct or continue any research or development of any ROFN Product.

(i) if such transaction results in a Change of Control of such Party, then such new Affiliate shall have the right to continue such Competing Program and such continuation shall not constitute a breach of such Party’s exclusivity obligations set forth in Section 2.6(a) or 2.6(b), respectively; provided that such new Affiliate conducts such Competing Program independently of the activities of this Agreement and does not use any of the other Party’s intellectual property rights or Confidential Information (except as may be separately licensed by such other Party to such new Affiliate) in the conduct of such Competing Program; and

(ii) if such transaction does not result in a Change of Control of such Party, then such Party and its new Affiliate shall have twelve (12) months from the closing date of such transaction to wind down or complete the divestiture of such Competing Program, and its new Affiliate’s conduct of such Competing Program during such twelve (12)-month period shall not be deemed a breach of such Party’s exclusivity obligations set forth above; provided that such new Affiliate conducts such Competing Program during such twelve (12)-month period independently of the activities of this Agreement and does not use any of the other Party’s intellectual property or Confidential Information (except as may be separately licensed by such other Party to such new Affiliate) in the conduct of such Competing Program. “ Divestiture ”, as used in this Section 2.6(e)(ii), means the sale or transfer of rights to the Competing Program to a Third Party without receiving a continuing share of profit, royalty payment or other economic interest in the success of such Competing Program.

It is the expectation of the Parties that the JDC will set forth the general principles and strategies upon which the Parties will perform their activities under the Development Plans. The JDC shall have only the powers expressly assigned to it in this Section 3.1 and all other matters are expressly excluded. In no event shall the JDC have the right to amend, modify, or waive compliance with this Agreement.

(b) Members . Each Party shall initially appoint up to three (3) representatives to the JDC. Each Party may change the number of its representatives and may replace its representatives at any time upon written notice to the other Party; provided that neither Party shall have more than three (3) representatives in the JDC and each representative shall be an officer or employee of the applicable Party or its Affiliate having sufficient experience and responsibility within such Party to make decisions arising within the scope of the JDC’s responsibilities. The JDC shall have a chairperson selected by Jazz. The role of the chairperson shall be to convene and preside at the meetings of the JDC and to ensure the preparation of meeting minutes, but the chairperson shall have no additional powers or rights beyond those held by other JDC representatives.

(c) Meetings . The JDC shall meet at least two (2) times per calendar year, unless the Parties mutually agree in writing to a different frequency for such meetings. Either Party may also call a special meeting of the JDC (by videoconference or teleconference) by at least ten (10) Business Days’ prior written notice to the other Party, and such Party shall provide the JDC, no later than ten (10) Business Days prior to the special meeting, with materials reasonably adequate to enable informed discussion or decision-making, as applicable.

22.

actions taken at such meeting and further issues to be considered. The JDC chairperson shall send draft meeting minutes to each member of the JDC for review and approval within ten (10) Business Days after each JDC meeting. Such minutes shall be deemed approved unless one or more members of the JDC object to the accuracy of such minutes within ten (10) Business Days of receipt. The JDC may be disbanded at any time by the mutual agreement of the Parties, it being understood that matters previously to be considered by the JDC shall be considered directly by the Parties in good faith with the decision making allocation as described below in the event of any dispute on such matters.

3.2 Joint Management Team

(a) Formation . Promptly, and in any event within thirty (30) days after the Effective Date, the Parties shall establish a joint management team (the “ Joint Management Team ” or “ JMT ”) and such JMT will:

(i) Manage and coordinate the strategic relationship of the Parties in the performance of the obligations under this Agreement; and

(ii) Address and resolve any disputes of the JDC.

(b) Members . Each Party shall appoint one senior executive to the JMT. Each Party may replace its representative at any time upon written notice to the other Party; provided that each representative shall be an executive of the applicable Party or its Affiliate having sufficient experience and responsibility within such Party to make decisions arising within the scope of the JMT’s responsibilities.

(c) Meetings . The JMT shall meet at least one (1) time per calendar year. Either Party may also call a special meeting of the JMT (by videoconference or teleconference) by at least ten (10) Business Days’ prior written notice to the other Party, and such Party shall provide the other member, no later than ten (10) Business Days prior to the special meeting, with materials reasonably adequate to enable informed discussion or decision-making, as applicable. The JMT may meet in person, by videoconference or by teleconference, as the Parties agree. Each Party shall bear the expense of its respective JMT members’ participation in JMT meetings. Meetings of the JMT shall be effective only if both representatives are present or participating in such meeting.

3.3 Decision Making . The JDC and JMT each shall strive to act by consensus. The representatives from each Party on the JDC will have, collectively, one (1) vote on behalf of that Party; each Party will have one vote on the JMT. If the JDC is unable to reach consensus on any matter within the JDC’s authority within thirty (30) days after first considering such matter, then such matter shall be referred to the JMT for resolution. If the JMT, after good faith efforts and consideration of the other party’s position, cannot resolve such matter within thirty (30) days after such matter has been referred to the JMT, then:

(a) Jazz shall have the final decision making authority with respect to all matters relating to the HemOnc Products; provided that such final decision making authority shall not apply with respect to (i) the prosecution and enforcement of Pfenex Patents (for which

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

23.

decisions shall be made as set forth in Sections 7.3 and 7.4), and (ii) material changes to the Pfenex Expression Feasibility Activities;

(b) prior to Option Exercise, Pfenex shall have the final decision making authority with respect to all matters relating to the development of the Pegaspargase Product; provided that Pfenex may not materially change any of its development obligations outlined in the applicable Development Plan with respect to the Pegaspargase Product without Jazz’s prior written consent; and

(c) prior to ROFN Exercise with respect to the applicable ROFN Product, Pfenex shall have the final decision making authority with respect to all matters relating to the development of such ROFN Product.

Notwithstanding the foregoing, a Party may not exercise such final decision making authority in a manner that would increase the financial obligations of the other Party. For clarity, the JDC and JMT have no authority to determine, and neither Party may exercise final-decision making authority to resolve, the achievement of a milestone set forth on Exhibit 6.3 or the allocation of responsibility for any delay in achievement thereof.

3.4 Working Groups . From time to time, the JDC may establish and delegate duties to other committees, sub-committees or directed teams (each, a “ Working Group ”) on an “as-needed” basis to oversee particular projects or activities, which delegation shall be reflected in the minutes of the meetings of the JDC. For illustrative purposes only, the JDC may establish a Working Group focused on CMC matters and a Working Group focused on intellectual property matters. Each Working Group shall be constituted and shall operate as the JDC determines and shall report to the JDC. Each Working Group and its activities shall be subject to the oversight, review and approval of the JDC. In no event shall the authority of the Working Group exceed that specified for the JDC in Section 3.1(a). Any disagreement between the designees of Pfenex and of Jazz on a Working Group shall be referred to the JDC for resolution.

Each Party shall also provide the Valuation Firm (with a copy to the other Party) with all information reasonably requested by the Valuation Firm regarding such Royalty Valuation Proposal and any other information such Party reasonably deems relevant to the Valuation Firm’s determination of the Royalty Valuation. Within thirty (30) days after the expiration of the fifteen (15)-day period set forth in this Section 6.6(e) above, the Valuation Firm shall select one of the final Royalty Valuation Proposals for such HemOnc Product so submitted by one of the Parties as the Royalty Valuation for such HemOnc Product, but may not alter the terms of any final Royalty Valuation Proposal and may not determine the Royalty Valuation for such HemOnc Product in a manner other than by selection of one of the submitted final Royalty Valuation Proposals for such HemOnc Product.

clause (i), (iii) this Agreement shall be deemed amended to reflect the payment of the Royalty Valuation and the termination of the obligation to pay royalties, as set forth in this Section 6.6(e); and (iv) each Party shall be responsible for fifty percent (50%) of the amounts invoiced by the Valuation Firm to conduct the Royalty Valuation. If Jazz does not elect to pay the Royalty Valuation or does not provide Pfenex with notice of its election within such thirty (30)-day period, then Section 6.5 will remain unchanged for such HemOnc Product, and Jazz shall be solely responsible for the amounts invoiced by the Valuation Firm to determine the Royalty Valuation.

6.7 Foreign Exchange . The rate of exchange to be used in computing the amount of currency equivalent in Dollars of Net Sales invoiced in other currencies shall be the rate used by Jazz in its financial reporting in accordance with applicable GAAP or other standard as then-used by Jazz.

6.8 Manner and Place of Payment . All payments owed by Jazz under this Agreement shall be made by wire transfer in immediately available funds to a bank and account designated in writing by Pfenex.

6.9 Records; Audits . Jazz agrees that it and all other Selling Parties will maintain complete and accurate records in reasonably sufficient detail to permit Pfenex to confirm the accuracy of the calculation of royalty payments and the achievement of sales milestone events. Upon reasonable prior notice, such records shall be available during regular business hours for a period of three (3) years from the end of the calendar year to which they pertain for examination, not more often than once each calendar year, by an independent certified public accountant selected by Pfenex and reasonably acceptable to Jazz, for the sole purpose of verifying the accuracy of the financial reports furnished by Jazz pursuant to this Agreement. Any such auditor shall enter into a confidentiality agreement with Jazz and shall not disclose Jazz’s Confidential Information to Pfenex or to any Third Party, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by Jazz or the amount of payments due by Jazz to Pfenex under this Agreement. Any amounts shown to be owed but unpaid shall be paid by Jazz to Pfenex, and any amounts showed to be overpaid will be refunded by Pfenex to Jazz, within forty-five (45) days from the accountant’s report. Pfenex shall bear the full cost of such audit unless such audit discloses an underpayment by Jazz of more than ten percent (10%) of the amount due, in which case Jazz shall bear the full cost of such audit.

6.10 Taxes .

(a) Taxes on Income . Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the efforts of the Parties under this Agreement.

(b) Tax Cooperation . The Parties agree to cooperate with one another and use reasonable efforts to reduce or eliminate tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Jazz to Pfenex under this Agreement.

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

36.

Pfenex an official tax certificate or other evidence of such withholding sufficient to enable Pfenex to claim such payment of taxes. Pfenex shall provide Jazz any tax forms that may be reasonably necessary in order for Jazz not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by applicable Laws, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or value added tax.

(c) Withholding Tax Action . If either Party (or its Affiliates or successors) is required to make a payment to the other Party subject to a deduction or withholding of tax, then (A) if such deduction or withholding of tax obligation arises as a result of any action by the first Party, such as a Change of Control, change of domicile, or assignment by such first Party and such action has the effect of increasing the amount of tax deducted or withheld (a “ Withholding Tax Action ”), then the amount payable by the Party taking such Withholding Tax Action (in respect of which such increased deduction or withholding is required to be made) shall be increased by the amount necessary (the “ Additional Amounts ”) to ensure that the other Party receives the same amount that it would have received had no such Withholding Tax Action occurred, and (B) the Additional Amounts shall be deducted and withheld by the Party paying the Additional Amounts. The Additional Amounts, along with any other tax deducted and withheld from the payment made by such Party, shall be timely remitted to the proper Governmental Authority for the account of the other Party in accordance with applicable Law. Notwithstanding the foregoing, any sublicense or assignment in contravention of Sections 2.1(d) or 13.6, respectively, of this Agreement will not constitute a Withholding Tax Action.

(d) Refund of Additional Amounts . In the event a Party actually receives a credit against any tax on its income for any Additional Amounts paid to a Governmental Authority on its behalf (whether for the taxable year with respect to which such Additional Amounts are deducted and withheld, or in any prior or subsequent taxable year), the Party obtaining such credit shall refund and pay to the other Party an amount equal to the lesser of the credit obtained and such Additional Amounts. Whether a credit is obtained for Additional Amounts or for other taxes paid by a Party shall be determined in a manner consistent with applicable Laws.

As between the Parties, Jazz shall own all rights in the Product Marks and shall register and maintain, in its discretion and at its own cost and expense, the Product Marks in the countries and regions in the Territory that it determines to be appropriate. Jazz shall have the sole right, in its discretion and at its expense, to defend and enforce the Product Marks.

(i) if Pfenex terminates with respect to HemOnc-Pf, then Section 11.4(a) applies;

(ii) if Pfenex terminates with respect to HemOnc-NextGen, then Section 11.4(b) applies;

(iii) if Pfenex terminates with respect to the Pegaspargase Product, then Section 11.4(c) applies;

13.2 Rights in Bankruptcy .

(a) 365(n) Rights .

(i) The Parties agree that all rights and licenses granted under or pursuant to this Agreement by one Party to the other are, for all purposes of Title 11 of the United States Code (“ Title 11 ”), licenses of rights to “intellectual property” as defined in Title 11, and, in the event that a case under Title 11 is commenced by or against either Party (the “ Bankrupt Party ”), the other Party shall have all of the rights set forth in Section 365(n) of Title 11 to the maximum extent permitted thereby. During the Term, each Party shall create and maintain current copies to the extent practicable of all such intellectual property. Without limiting the Parties’ rights under Section 365(n) of Title 11, if a case under Title 11 is commenced by or against the Bankrupt Party, the other Party shall be entitled to a copy of any and all such intellectual property and all embodiments of such intellectual property, and the same, if not in the possession of such other Party, shall be promptly delivered to it (i) before this Agreement is rejected by or on behalf of the Bankrupt Party, within thirty (30) days after the other Party’s written request, unless the Bankrupt Party, or its trustee or receiver, elects within thirty (30) days to continue to perform all of its obligations under this Agreement, or (ii) after any rejection of this Agreement by or on behalf of the Bankrupt Party, if not previously delivered as provided under clause(i) above. All rights of the Parties under this Section 13.2 and under Section 365(n) of Title 11 are in addition to and not in substitution of any and all other rights, powers, and remedies that each party may have under this Agreement, Title 11, and any other applicable Laws. The non-Bankrupt Party shall have the right to perform the obligations of the Bankrupt Party hereunder with respect to the maintenance of such intellectual property, but neither such provision nor such performance by the non-Bankrupt Party shall release the Bankrupt Party from any such obligation or liability for failing to perform it.

(ii) The Parties agree that they intend the foregoing non-Bankrupt Party rights to extend to the maximum extent permitted by law and any provisions of applicable contracts with Third Parties, including for purposes of Title 11, (i) the right of access to any intellectual property (including all embodiments thereof) of the Bankrupt Party or any Third Party with whom the Bankrupt Party contracts to perform an obligation of the Bankrupt Party under this Agreement, and, in the case of the Third Party, which is necessary for the Development, Regulatory Approval and manufacture of Products and (ii) the right to contract directly with any Third Party described in (i) in this sentence to complete the contracted work.

(iii) Any intellectual property provided pursuant to the provisions of this Section 13.2 shall be subject to the licenses set forth elsewhere in this Agreement and the

payment obligations of this Agreement, which shall be deemed to be royalties for purposes of Title 11.

(b) Prosecution of Patents . Notwithstanding anything to the contrary in Article 7, in the event that Pfenex is the Bankrupt Party, Jazz may take appropriate actions in connection with the filing, prosecution, maintenance and enforcement of any Pfenex Patent licensed to Jazz under this Agreement without being required to consult with Pfenex before taking any such actions, provided that such actions are consistent with this Agreement.

(c) Escrow .

(i) Establishment and Update . Within [***] days after Jazz’s written request, the Parties shall enter into an escrow agreement (the “ Escrow Agreement ”) with a mutually agreeable Third Party escrow agent (the “ Escrow Agent ”). The Escrow Agreement will contain terms and conditions that are typically included in such a technology escrow agreement, [***]. Under the Escrow Agreement, Pfenex shall, within [***] Business Days of execution of the Escrow Agreement, deposit with the Escrow Agent [***] (the “ Escrow Materials ”). Pfenex shall keep the Escrow Materials reasonably current and complete, and shall be updated by or on behalf of Pfenex from time to time and in no event more than [***] days after Pfenex has made one or more material modifications to any of the Escrow Materials. Jazz shall reimburse Pfenex for the reasonable out-of-pocket costs incurred by Pfenex in connection with the Escrow Agreement and preparation and deposit of Escrow Materials with the Escrow Agent.

(ii) Right to Use Escrow Materials . Following an Escrow Triggering Event, Jazz may access and use [***] the Escrow Materials [***], and, effective as of an Escrow Triggering Event, [***].

(d) Development Step-In . In addition to its other rights under this Agreement, and notwithstanding anything herein to the contrary, upon the occurrence of the Development Step-In Triggering Event, Jazz may notify Pfenex in writing that a Development Step-In Trigger Event has occurred. Pfenex shall have [***] Business Days to dispute the occurrence of the Development Step-In Triggering Event. If Pfenex disputes such occurrence, the Parties shall discuss in good faith. If Pfenex agrees that a Development Step-In Triggering Event has occurred, or does not respond within such [***]-Business Day period, [***].

(e) Technology Transfer and Assistance . In connection with Jazz’s rights to access and use the Escrow Materials pursuant to Section 13.2(c)(ii), Pfenex shall provide to Jazz [***].

13.3 Force Majeure . Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting force majeure continues and the nonperforming Party takes reasonable efforts to remove the condition. For purposes of this Agreement, force majeure shall include conditions beyond the control of the Parties, including an act of God, war, civil commotion, terrorist act, labor strike or lock-out,

Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a force majeure affecting such Party. If a force majeure persists for more than ninety (90) days, then the Parties will discuss in good faith the modification of the Parties’ obligations under this Agreement in order to mitigate the delays caused by such force majeure.

DUBLIN and SAN DIEGO July 27, 2016 — Jazz Pharmaceuticals plc (Nasdaq: JAZZ) and Pfenex Inc.
