 LICENSES AND
EXCLUSIVITY 
 2.1 License to Jazz for HemOnc Products. 

(a) Election for HemOnc Products. Pfenex shall use Commercially Reasonable Efforts to perform the Pfenex Expression Feasibility
Activities for each of HemOnc-Pf and the Fused Protein. Pfenex shall promptly notify Jazz in writing if Pfenex reasonably believes, after using Commercially Reasonable Efforts, that it will not be able to achieve Successful Expression for either
HemOnc-Pf or the Fused Protein. Promptly following completion of the Pfenex Expression Feasibility Activities for each HemOnc Product, Pfenex shall promptly provide Jazz with the Expression Feasibility Data Package for such HemOnc Product. 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 the Expression Feasibility Data Package (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 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. 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). Commencing upon receipt of the Assessment Materials for each HemOnc Product, Jazz shall use
Commercially Reasonable Efforts to conduct the Jazz Assessment Activities with respect to such HemOnc Product. Prior to expiration of the Assessment Period for the applicable HemOnc Product, Jazz may provide Pfenex with written notice that Jazz
elects to terminate its license hereunder with respect to such HemOnc Product (with respect to such HemOnc Product, the “Declination Notice”). 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 immediately prior to expiration of the applicable Assessment Period for
purposes of Section 11.4. 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. Notwithstanding anything to the contrary in this Agreement, all licenses granted to Jazz pursuant to this
Agreement under the Production Techniques Patents shall be non-exclusive. Pfenex shall not grant a license under the Production Techniques Patents to any Third Parties to research, Develop, make, have made, use, sell, have sold, offer for sale,
import, or otherwise Commercialize any HemOnc Product in the Field in the Territory. 
 (c) Pfenex Retained Rights. Notwithstanding
the rights granted to Jazz in Section 2.1(b), Pfenex retains the non-exclusive right to practice the Pfenex IP in the Territory solely as necessary to (i) conduct the activities assigned to Pfenex under the Development Plans in accordance
with the terms of this Agreement; and (ii) manufacture the HemOnc Products solely for supply to Jazz, its Affiliates or its/their sublicensees and Marketing Partners. 

(d) Sublicenses. Jazz shall have the right to grant sublicenses through multiple tiers, under any or all of the rights granted in
Section 2.1(b), to its Affiliates and/or to Third Parties. Each agreement in which Jazz grants a sublicense under the Pfenex IP shall be consistent with the terms and conditions of this Agreement relevant to such sublicense. Jazz shall be
liable to Pfenex for the performance of its direct and indirect sublicensees, including their compliance with the applicable provisions of this Agreement. Jazz shall ensure that the efforts of each Third Party sublicensee to Develop and
Commercialize a Product shall be at least equivalent to Jazz’s Commercially Reasonable Efforts in accordance with Sections 4.4 and 5.2.

 2.2 License to Pfenex. Effective on commencement of the Pfenex Expression Feasibility
Activities for HemOnc-NextGen, Jazz shall, and hereby does, grant to Pfenex a non-exclusive, royalty-free, non-sublicenseable and non-transferable license or sublicense, under the Jazz Extension IP, solely as necessary (i) to conduct the Pfenex
activities for HemOnc-NextGen as specified in the Development Plan for such Product, and (ii) subject to the Parties’ agreement in accordance with Section 4.7, to manufacture HemOnc-NextGen for supply to Jazz or its designees. Jazz
shall disclose to Pfenex the potential Half-Life Extension Component(s) within the Jazz Extension IP (and any changes thereto) to be evaluated and/or used in the Development of HemOnc-NextGen under this Agreement to the extent necessary for Pfenex
to perform such activities. 
 2.3 No Implied Licenses. Except as explicitly set forth in this Agreement, neither Party shall be
deemed by estoppel or implication to have granted the other Party any license or other right to any intellectual property of such Party. All rights not otherwise expressly granted hereunder by a Party shall be retained. 

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 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. 

  
 16. 

[***] 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. 








 (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. 

(e) If the Parties are unable to reach agreement upon and do not enter into a mutually acceptable Option Exercise Agreement within
three (3) months from Jazz’s delivery of

[***] 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. 








 
the Option Exercise Notice, then either Party shall have the right to 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. If the Parties are unable to reach mutual agreement on the terms of the Option Exercise Agreement within such three (3)-month period, Jazz may have the terms and conditions of the Option Exercise
Agreement determined by baseball arbitration in accordance with Section 12.2(b), and the Parties shall promptly enter into the Option Exercise Agreement on such terms decided by such arbitration; provided that Jazz initiates such arbitration
within sixty (60) days after such three (3)-month negotiation period. 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. Jazz shall have the right to exercise the ROFN for each ROFN
Product by delivery of written notice to Pfenex (a “ROFN Exercise Notice”) within sixty (60) days of Jazz’s receipt of the ROFN Data Package for such ROFN Product in accordance with the terms of this Section 2.5. If
Jazz does not provide a ROFN Exercise Notice to Pfenex within sixty (60) days after Jazz’s receipt of the applicable ROFN Data Package, then Jazz’s ROFN shall lapse only with respect to such ROFN Product. 

(b) ROFN Data Package. Pfenex shall keep Jazz reasonably informed of material research and development activities with respect to each
ROFN Product through the regular meetings of the JDC, including by providing summaries in reasonable detail of any material data generated in connection with such activities. Following the completion of IND-enabling toxicology studies for a ROFN
Product and in all events prior to the filing of an IND for such ROFN Product, Pfenex shall provide to Jazz the ROFN Data Package for such ROFN Product. 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 such ROFN Data Package (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 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) 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 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 such ROFN Product during the negotiation period. The terms of such ROFN Exercise
Agreement shall be commercially reasonable and provide usual and customary terms for such arrangements. 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.

set forth in Section 2.6(a) and (b) shall thereafter no longer apply with respect to products containing [***]. 
 (ii) If
this Agreement is terminated with respect to HemOnc-NextGen, the exclusivity obligations set forth in Section 2.6(a) and (b) shall thereafter no longer apply with respect to products containing [***]. 

(iii) If either this Agreement is terminated with respect to the Pegaspargase Product or the Option expires without Option Exercise,
the exclusivity obligations set forth in Section 2.6(a) and (b) shall no longer apply with respect to products containing or comprising [***]; provided that the ROFN in Section 2.5 shall continue to apply. 

For clarity, clauses (i), (ii) and (iii) above are cumulative (i.e., more than one clause may apply). 

(d) ROFN Products. 

(i) In the event that, with respect to a particular [***] ROFN Product, Jazz declines its ROFN, Jazz’s ROFN expires without
delivery by Jazz to Pfenex of a ROFN Exercise Notice or the Parties do not enter into a ROFN Exercise Agreement for such ROFN Product in accordance with the terms of Section 2.5, then Sections 2.6(a) shall no longer apply to such ROFN Product.
Pfenex may not file an IND for a [***] ROFN Product until Jazz declines its ROFN, Jazz’s ROFN expires without delivery by Jazz to Pfenex of a ROFN Exercise Notice, or the Parties fail to enter into a ROFN Exercise Agreement for such ROFN
Product in accordance with the terms of Section 2.5. 
 (ii) Pfenex’s obligations under Section 2.6(a) shall continue
to apply to any [***] ROFN Product, regardless of whether Jazz declines its ROFN, Jazz’s ROFN expires without delivery by Jazz to Pfenex of a ROFN Exercise Notice, or the Parties fail to enter into a definitive ROFN Exercise Agreement.

that, if conducted by such Party, would cause such Party to be in breach of its exclusivity obligations set forth above (a “Competing Program”), then: 

(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

 (b) “EU Approval” means the later of (i) first achievement
of MAA approval in the European Union by the centralized procedure or in at least three of the five Major European Countries; and (b) first receipt of Pricing Approval in at least three Major European Countries, provided that Jazz uses
Commercially Reasonable Efforts to obtain such Pricing Approvals after the corresponding MAA approval. 
 (c) For clarity, in the
case of development milestone events numbered 1 through 4 listed on Exhibit 6.3 only, if any such higher numbered development milestone event for a particular HemOnc Product is achieved and any such lower numbered development milestone
event for such HemOnc Product has not yet been achieved for any reason, notwithstanding anything herein to the contrary, such lower numbered development milestone event shall be deemed to have been achieved and the corresponding development
milestone payment listed on Exhibit 6.3 shall be payable simultaneously with the development milestone payment for achievement of such higher numbered development milestone event. 

6.4 Sales Milestones for HemOnc-NextGen. Jazz shall notify Pfenex, concurrently with the delivery of the royalty report under
Section 6.5(d), after the end of the calendar quarter in which the aggregate annual Net Sales of HemOnc-NextGen by Jazz and its Affiliates and sublicensees first reaches each of the amounts specified on Exhibit 6.4.
Thereafter, Pfenex shall invoice Jazz for the corresponding milestone payment set forth on Exhibit 6.4, and Jazz shall pay each such invoice within thirty (30) days after receipt thereof. Each such sales milestone payment
shall be payable one time only. For clarity, the milestone payments in Exhibit 6.4 shall be additive such that if more than one milestone below is met in the same calendar year, Jazz

requested with respect to the omitted portions. 








 
shall pay all applicable payments to Pfenex for that calendar year in accordance with this Section 6.4. 

6.5 Royalties on HemOnc Products. 

(a) Royalty Rates. Subject to Sections 6.5(b) and 6.5(c), Jazz shall pay to Pfenex royalties on aggregate annual Net Sales of HemOnc-Pf
and HemOnc-NextGen, as calculated by multiplying the applicable royalty rate by the corresponding amount of Net Sales of HemOnc-Pf and HemOnc-NextGen in each calendar year as set forth on Exhibit 6.5(a). For clarity, Net Sales
and the applicable royalty rate shall be determined separately for each of HemOnc-Pf and HemOnc-NextGen. 
 (b) Royalty Term.
Royalties shall be paid under this Section 6.5, on a Product-by-Product basis, for so long as Jazz or any other Selling Party is Commercializing or having Commercialized the HemOnc Products (with respect to each Product, the “Royalty
Term”). 
 (c) Third Party Royalty Stacking. If Jazz obtains a license from a Third Party to any intellectual
property right in order to manufacture, import, sell or Commercialize a HemOnc Product, Jazz shall have the right to deduct, from the royalty payment that would otherwise have been due pursuant to this Section 6.5 with respect to Net Sales of
such HemOnc Product in the applicable country in a particular calendar quarter, an amount equal to [***] of the royalties paid by Jazz to such Third Party pursuant to such license on account of the sale of such HemOnc Product in such country during
such calendar quarter; [***]. Jazz shall not be entitled to any reduction for any Third Party payments made under any intellectual property licensed by Jazz from any Third Party as of the Effective Date or for any Jazz Extension IP. 

(d) Royalty Reports and Payments. Within forty-five (45) days after the end of each calendar quarter (or sixty
(60) days for the last calendar quarter of the calendar year) after the First Commercial Sale of any HemOnc Product, Jazz shall deliver to Pfenex a statement, on a country-by-country and Product-by-Product basis, of the amount of gross sales
and Net Sales of the HemOnc Products during the applicable calendar quarter and a calculation of the amount of royalty payment due on such sales for such calendar quarter, including royalty reduction under Section 6.5(c), if applicable.
Following receipt of each royalty report, Pfenex shall invoice Jazz for the royalty payment, and Jazz shall pay each such invoice within fifteen (15) days after receipt thereof. 

(e) Third Party Payments. Pfenex will be solely responsible for all amounts owed to Third Parties pursuant to agreements between Pfenex
and Third Parties with respect to HemOnc Products. 
 6.6 HemOnc-Pf COGS Improvement Sharing. In addition to amounts payable under
Section 6.5, for HemOnc-Pf sold by Jazz and other Selling Parties in a particular calendar year, Jazz shall pay to Pfenex an amount equal to the COGS Improvement. Within sixty (60) days after the end of each calendar year after the First
Commercial Sale of HemOnc-Pf, Jazz shall deliver to Pfenex a statement of the calculation of COGS Variance in accordance with Exhibit D and amount of COGS Improvement sharing payment due for such calendar year.


  
 33. 

[***] 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. 








 
Following receipt of each such report, Pfenex shall invoice Jazz for the COGS Improvement sharing payment, and Jazz shall pay each such invoice within forty-five (45) days after receipt
thereof. 
 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 COGS Improvement sharing 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. To the extent Jazz is
required to deduct and withhold taxes on any payment to Pfenex, Jazz shall deduct the amounts of such taxes from the payment to Pfenex, pay such amounts to the proper Governmental Authority in a timely manner and promptly transmit to 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 

  
 34. 

[***] 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. 








 
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.

(c) Pfenex Improvements. Notwithstanding Sections 7.1(a) and 7.1(b) and subject to Section 7.1(g), Pfenex shall solely own all
Inventions (developed solely by or on behalf of a Party or jointly by or on behalf of the Parties) that constitute an improvement, modification or enhancement of Pfenex’s proprietary P. fluorescens protein expression and manufacturing
technology that has been disclosed by Pfenex to Jazz in writing (the “Disclosed Platform”), where such improvement, modification, and enhancement is applicable to the manufacture of drug substance for products in addition to the
Products, including (i) improvements, modifications and enhancements to the Disclosed Platform generated under this Agreement (excluding, for clarity, any protein sequence), and (ii) growth media and conditions generally applicable to
P. fluorescens and products that do not contain [***], but excluding (A) Post-Primary Recovery Inventions and (B) any Inventions, Information, or improvements relating to the process of formulating a Product or the formulated
Product (the “Pfenex Improvements”). To the extent any Pfenex Improvement is made by Jazz’s or its Affiliates’ employees, agents, or independent contractors (whether solely or jointly with Pfenex), Jazz hereby assigns to
Pfenex all of the right, title and interest in and to such Pfenex Improvement. 
 (d) Jazz Improvements. Notwithstanding Sections
7.1(a) and 7.1(b), Jazz shall solely own all Inventions (developed solely by or on behalf of a Party or jointly by or on behalf of the Parties) that constitute an improvement, modification or enhancement of the Half-Life Extension Component for
HemOnc-NextGen selected by Jazz, in its sole discretion, including any fusion protein comprised of [***] together with a Half-Life Extension Component (the “Jazz Improvements”). To the extent any Jazz Improvement is made by
Pfenex’s or its Affiliates’ employees, agents, or independent contractors (whether solely or jointly with Jazz), Pfenex hereby assigns to Jazz all of the right, title and interest in and to such Jazz Improvement. 

(e) Product Licenses. Pfenex Improvements, Sole Inventions owned by Pfenex, and Pfenex’s interest in Joint Inventions shall be
included in Pfenex IP and automatically licensed to Jazz under Section 2.1. Jazz Improvements shall be included in Jazz Extension IP and automatically licensed to Pfenex under Section 2.2.

contains [***] or includes a Half-Life Extension Component. In addition to the license grant contained in Section 7.1(e), Jazz hereby grants to Pfenex a non-exclusive, worldwide, transferrable, fully paid, perpetual, irrevocable, sublicenseable
(through multiple tiers) license under Jazz Improvements Controlled by Jazz assigned by Pfenex to Jazz under Section 7.1(d) solely to use with Pfenex’s proprietary P. fluorescens manufacturing platform to manufacture biological
products. For clarity, the foregoing licenses granted by each Party expressly exclude (by implication or otherwise) any license or other right to practice any other intellectual property right Controlled by a Party that may be necessary or useful to
practice the subject Jazz Improvement or Pfenex Improvement, as applicable.

requested with respect to the omitted portions. 








 (g) Post-Primary Recovery Inventions. Notwithstanding Sections 7.1(a), 7.1(b), and
7.1(c), the Parties shall jointly own all Inventions (developed solely by or on behalf of a Party or jointly by or on behalf of the Parties) made prior to completion of the applicable Manufacturing Process Transfer that constitute a process, or an
improvement, modification, or enhancement of a process, used in the manufacture of proteins following the primary recovery of such proteins, excluding any Inventions, Information, or improvements relating to the process of formulating a Product or
the formulated Product (the “Post-Primary Recovery Inventions”). To the extent any Post-Primary Recovery Invention is made solely by the employees, agents, or independent contractors of a Party or its Affiliates, such Party hereby
assigns to the other Party a joint ownership interest in and to such Post-Primary Recovery Invention such that the Parties shall jointly own such Post-Primary Recovery Invention. For clarity, after completion of the applicable Manufacturing Process
Transfer, Sections 7.1(a) and 7.1(b) shall govern ownership of Inventions that constitute a process, or an improvement, modification, or enhancement of a process, used in the manufacture of proteins following the primary recovery of such proteins.
Neither Party may file a Patent on Post-Primary Recovery Inventions without the consent of the other Party, such consent not to be unreasonably withheld, conditioned, or delayed. 

7.2 Disclosure of Inventions. Each Party shall promptly disclose to the other Party, subject to any Third Party obligations, all
Inventions made by such Party to which the other Party has rights hereunder, including any invention disclosures, or other similar documents, submitted to it by its employees, agents or independent contractors describing such Inventions, and shall
promptly respond to reasonable requests from the other Party for additional Information relating to such Inventions.

 37. 

[***] 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. 








 
property as may be established by the JDC. Pfenex shall file patents covering Sole Inventions owned by Pfenex in a manner to separate the claims specifically related to a Product from other
subject matter to the extent possible and in consultation with Jazz, 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 a Product. If Pfenex decides to no longer prosecute or maintain any Pfenex Product-Specific Patent in any jurisdiction in the Territory, it shall notify Jazz in writing. Thereafter, Jazz shall have the right to prosecute and maintain such
Pfenex Product-Specific Patent in such jurisdiction at its own cost and expense. If Pfenex decides to no longer prosecute or maintain any Pfenex General Product Patent, it shall notify Jazz in writing. Thereafter, Jazz shall have the right to
prosecute and maintain such Pfenex General Product Patent in such jurisdiction 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 a Product. 
 (c) Joint Patents. As between the Parties, Jazz shall have the first right
to file, prosecute and maintain all Joint Patents, at its own cost and expense. Jazz shall consult with Pfenex and keep Pfenex reasonably informed of the status of the Joint Patents and shall promptly provide Pfenex with all material correspondence
received from any patent authority in connection therewith. In addition, Jazz shall promptly provide Pfenex with drafts of all proposed material filings and correspondence to any patent authority with respect to the Joint Patents for Pfenex’s
review and comment prior to the submission of such proposed filings and correspondences. Jazz shall confer with Pfenex and consider in good faith Pfenex’s comments prior to submitting such filings and correspondences. If Jazz decides to no
longer prosecute or maintain any Joint Patent in any jurisdiction in the Territory, it shall notify Pfenex in writing. Thereafter, Pfenex shall have the right to prosecute and maintain such Joint Patent in such jurisdiction at its own cost and
expense. 
 (d) Cooperation. Each Party shall provide the other Party all reasonable assistance and cooperation, at the other
Party’s request and expense, in the patent prosecution efforts provided above in this Section 7.3, including providing any necessary powers of attorney, executing any other required documents or instruments for such prosecution, and making
its personnel with appropriate scientific expertise available to assist in such efforts. 
 7.4 Patent Enforcement. 

(a) Notification. If either Party becomes aware of (i) any existing or threatened infringement of any Pfenex Patent in the
Territory, which infringing activity involves the using, making, importing, exporting, offering for sale or selling Products or products that otherwise are competitive with Products, (ii) a declaratory judgment action asserting the invalidity,
unenforceability or non-infringement of any Pfenex Patent in the Territory in connection with any infringement described in clause (i), or (iii) an application for a Biosimilar Product (defined below) referencing a Product submitted to a Party
or a Regulatory Authority for Regulatory Approval (each of (i), (ii), and (iii) a “Product Infringement”), it shall promptly notify the other Party in writing to that effect, and the Parties will consult with each other
regarding any actions to be taken with respect to such Product Infringement. For purpose of this definition, “Biosimilar Product” means, with respect to a particular Product in a particular country in the Territory, any
pharmaceutical product that is claimed to be biosimilar to or 

  
 38. 

[***] 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. 








 
interchangeable with such Product (including a product that is the subject of an application submitted under Section 351(k) of the Public Health Service Act as set forth at 42 U.S.C. Chapter
6A, as amended, citing the Product as the reference product) or for which the BLA otherwise references or relies on such Product or any corresponding foreign application in the Territory, including, with respect to the European Union, a Marketing
Authorization Application filed with the EMA pursuant to the centralized approval procedure or with the applicable Regulatory Authority of a country in Europe with respect to the mutual recognition or any other national approval. 

(b) Enforcement Rights. For any Product Infringement, each Party shall share with the other Party all information available to
it that may be shared subject to Third Party obligations regarding such alleged infringement, pursuant to a mutually agreeable “common interest agreement” executed by the Parties under which the Parties agree to their shared, mutual
interest in the outcome of any suit to enforce the Pfenex Patents against such Product Infringement. 
 (i) Jazz shall have the
first right, but not the obligation, to bring an appropriate suit or take other action against any person or entity engaged in, or to defend against, a Product Infringement to the extent involving infringement of (A) any Pfenex Product-Specific
Patent and (B) any Pfenex General Product Patent. Jazz shall consult with Pfenex and keep Pfenex reasonably informed of the status of the enforcement of such Pfenex Product-Specific Patent or Pfenex General Product Patent, as the case may be.
Jazz shall consider Pfenex’s comments with respect to the enforcement of such Pfenex General Product Patent in good faith. Jazz shall not settle any such suit or action without providing Pfenex an opportunity to review and comment on such
proposed settlement. Jazz shall not settle any such suit or action with respect to a Pfenex General Product Patent if Pfenex promptly notifies Jazz that it reasonably and in good faith believes that doing so would cause a material adverse effect on
Pfenex’s intellectual property rights covering products other than a Product. 
 (ii) If Jazz does not, within one hundred
eighty (180) days after its receipt or delivery of notice under Section 7.4(a), commence a suit to enforce an applicable Pfenex Sole Patent, take other action to terminate such Product Infringement with respect to an applicable Pfenex Sole
Patent, or initiate a defense against such Product Infringement with respect to an applicable Pfenex Sole Patent, then upon Jazz’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed, Pfenex shall have the
right, but not the obligation, to commence such a suit or take such an action to enforce the applicable Pfenex Sole Patent. In such event, Jazz shall take appropriate actions in order to enable Pfenex to commence a suit or take the actions set forth
in the preceding sentence. Pfenex shall not settle any such suit or action in any manner that would negatively impact the applicable Pfenex Sole Patent or that would limit or restrict the ability of Jazz to sell Products anywhere in the Territory
without the prior written consent of Jazz. 
 (c) Collaboration. Each Party shall provide to the enforcing Party reasonable
assistance in such enforcement, at such enforcing Party’s request and expense, including joining such action as a party plaintiff to ensure legal standing if required by applicable Laws to pursue such action or if requested by the enforcing
Party. The enforcing Party shall keep the other Party regularly informed of the status and progress of such enforcement efforts and shall reasonably 

  
 39. 

[***] 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. 








 
consider the other Party’s comments on any such efforts. The non-enforcing Party shall be entitled to separate representation in such matter by counsel of its own choice and at its own
expense, but such Party shall at all times cooperate fully with the enforcing Party. 
 (d) Expenses and Recoveries. The Party
bringing or defending a claim, suit or action under Section 7.4(b) shall be solely responsible for any expenses incurred by such Party as a result of such claim, suit or action. If such enforcing Party recovers monetary damages in such claim,
suit or action, such recovery shall be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel), and any remaining amounts
shall be allocated as follows: (i) if Jazz is the enforcing or defending Party, the remaining amounts will be retained by Jazz, except that any imputed lost sales upon which such amounts were calculated shall be included in Net Sales subject to
the royalty payment by Jazz to Pfenex pursuant to Section 6.5, and (ii) if Pfenex is the enforcing or defending Party, the remaining amounts will be shared equally by Pfenex and by Jazz. 

7.5 Enforcement of Jazz Sole Patents and Joint Patents. Jazz shall have the sole right, but not the obligation, in the case of the Jazz
Sole Patents and the first right, but not the obligation, in the case of the Joint Patents to bring an appropriate suit or other action against any person or entity allegedly infringing any Jazz Sole Patents or Joint Patents, as the case may be, and
to defend against any declaratory judgment action against any Jazz Sole Patents or Joint Patents, as the case may be. In the case of any existing or threatened infringement of any Joint Patent in the Territory that does not involve the using,
making, importing, exporting, offering for sale or selling Products or products that otherwise are competitive with Products, if Jazz does not, within one hundred eighty (180) days after written request by Pfenex, commence a suit to enforce an
applicable Joint Patent or take other action to terminate such infringement with respect to an applicable Joint Patent, then Pfenex shall have the right, but not the obligation, to commence such a suit or take such other action to enforce the
applicable Joint Patent. Each Party shall provide reasonable assistance to the enforcing Party in such enforcement or defense, at such enforcing Party’s request and expense, including joining such action as a party plaintiff to ensure legal
standing if required by applicable Laws to pursue such action or if requested by such enforcing Party. If such enforcing Party recovers monetary damages in such claim, suit or action, such recovery shall be allocated first to the reimbursement of
any expenses incurred by the Parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel), and any remaining amounts shall be retained by such enforcing Party. 

7.6 Patent Term Extensions. Pfenex shall cooperate with Jazz, at Jazz’s request, in seeking and obtaining patent term extensions
(including any pediatric exclusivity extensions as may be available) or supplemental protection certificates or their equivalents in any country with respect to any Pfenex Product-Specific Patents and Products. If elections with respect to obtaining
such patent term extensions are to be made, Jazz shall consider in good faith any comments provided by Pfenex in regard to such elections, provided that Jazz have the sole right to make such elections with respect to any Pfenex Product-Specific
Patents. Pfenex shall further cooperate with Jazz, at Jazz’s request, in seeking and obtaining patent term extensions (including any pediatric exclusivity extensions as may be available) or supplemental protection certificates or their
equivalents in any country with respect to any Pfenex General Product Patents and Products, which Pfenex shall file and manage in good faith unless Pfenex has previously 

  
 40. 

[***] 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. 








 
extended the applicable Pfenex General Product Patent in connection with any product other than the applicable Product. 

7.7 Personnel Obligations. Prior to beginning work under this Agreement relating to any Development of a Product, each employee, agent
or independent contractor of a Party or its Affiliates shall be bound by invention assignment obligations that are consistent with the obligations of such Party in this Article 7, including: (a) promptly reporting any invention, discovery,
process or other intellectual property right; (b) assigning to such Party all of the right, title and interest in and to any invention, discovery, process or other intellectual property right; (c) cooperating in the preparation, filing,
prosecution, maintenance and enforcement of any Patent; (d) performing all acts and signing, executing, acknowledging and delivering any and all documents required for effecting the obligations and purposes of this Agreement; and
(e) complying with obligations of confidentiality and non-use consistent with those contained in this Agreement. 
 7.8
Trademarks. Jazz and its Affiliates and sublicensees shall have the right to brand the Products in the Territory using any trademarks it determines appropriate for the Products, which may vary by country or within a country (the “Product
Marks”), provided that Jazz shall not, and shall ensure that its Affiliates and sublicensees will not make any use of the trademarks or house marks of Pfenex (including Pfenex’s corporate name) or any trademark confusingly similar
thereto (except to the extent required by applicable Laws (e.g., to indicate the manufacturer of the Product)). 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. Pfenex shall not,
and shall ensure that its Affiliates and sublicensees will not, file or use any trademark confusingly similar to the Product Marks.

 9.1
Indemnification by Pfenex. Pfenex shall defend, indemnify, and hold harmless Jazz and its Affiliates and their respective officers, directors, employees, and agents (the “Jazz Indemnitees”) from and against any and all damages
or other amounts payable to a Third Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by such Jazz Indemnitees, resulting from any claims, suits, proceedings or causes of action brought by such Third
Party (collectively, “Claims”) against such Jazz Indemnitee to the extent arising from or based on (a) the Development or manufacture of Products by or on behalf of Pfenex or its Affiliates or sublicensees prior to the
Effective Date, (b) Pfenex’s and its Affiliates’ performance of the activities allocated to Pfenex under the applicable Development Plan, including the manufacture of Products, (c) the breach of any of Pfenex’s obligations,
representations or warranties under this Agreement, or (d) the willful misconduct or negligent acts of Pfenex, its Affiliates, or the officers, directors, employees, or agents of Pfenex or its Affiliates in connection with this Agreement. The
foregoing indemnity obligation shall not apply to the extent that (i) the Jazz Indemnitees fail to comply with the indemnification procedures set forth in Section 9.3 and Pfenex’s defense of the relevant Claims is prejudiced by such
failure, or (ii) any Claim arises from or is based on any activity set forth in Section 9.2 for which Jazz is obligated to indemnify the Pfenex Indemnitees under Section 9.2.  

9.2 Indemnification by Jazz. Jazz shall defend, indemnify, and hold harmless Pfenex and its Affiliates and their respective officers,
directors, employees, and agents (the “Pfenex Indemnitees”) from and against damages or other amounts payable to a Third Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by such Pfenex
Indemnitees, resulting from any Claims against such Pfenex Indemnitee to the extent arising from or based on (a) the Development, manufacture or Commercialization of Products by or on behalf of Jazz or its Affiliates or sublicensees (in each

employees, or agents of Jazz or its Affiliates in connection with this Agreement. The foregoing indemnity obligation shall not apply to the extent that (i) the Pfenex Indemnitees fail to comply with the indemnification procedures set forth in

Indemnitees under Section 9.1. 
 9.3 Indemnification Procedures. The Party claiming indemnity under this Article 9 (the

 44. 

[***] 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. 








 
sought (the “Indemnifying Party”) promptly after learning of such Claim. The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the
Indemnifying Party’s expense, in connection with the defense of the Claim for which indemnity is being sought. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided,
however, the Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice. Unless the settlement involves only the payment of money, the Indemnifying Party shall not settle any Claim without the
prior written consent of the Indemnified Party, such consent not to be unreasonably withheld, conditioned or delayed. So long as the Indemnifying Party is conducting the defense of the Claim in good faith, the Indemnified Party shall not settle or
compromise any such Claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (a) the Indemnified Party may defend against, consent to
the entry of any judgment, or enter into any settlement with respect to such Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying
Party in connection therewith), and (b) the Indemnifying Party shall remain responsible to indemnify the Indemnified Party as provided in this Article 9. 

9.4 Insurance. Each Party shall procure and maintain product liability insurance of at least [***] at all
times during which any Product is being clinically tested in human subjects and of at least [***] at all times during which any Product is being commercially distributed or sold by such Party and for the five (5)-year period thereafter. It is
understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 9. Each Party shall provide the other Party with written evidence of such
insurance upon request. Each Party shall provide the other Party with written notice at least thirty (30) days prior to the cancellation or non-renewal of such insurance. 

ARTICLE 10 

CONFIDENTIALITY 
 10.1
Confidentiality. Each Party agrees that, during the Term and for a period of ten (10) years thereafter, it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in
this Agreement (which includes the exercise of any rights or the performance of any obligations hereunder) any Confidential Information furnished to it by the other Party pursuant to this Agreement, except to the extent expressly authorized by this
Agreement or otherwise agreed in writing by the Parties. The foregoing confidentiality and non-use obligations shall not apply to any portion of the other Party’s Confidential Information that the receiving Party can demonstrate by competent
written proof: 
 (a) was already known to the receiving Party or its Affiliate, other than under an obligation of confidentiality,
at the time of disclosure by the other Party; 
 (b) was generally available to the public or otherwise part of the public domain at
the time of its disclosure to the receiving Party;

[***] 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. 








 (c) became generally available to the public or otherwise part of the public domain after
its disclosure and other than through any act or omission of the receiving Party in breach of this Agreement; 
 (d) was disclosed to
the receiving Party or its Affiliate by a Third Party who has a legal right to make such disclosure and who did not obtain such information directly or indirectly from the other Party; or 

(e) was independently discovered or developed by the receiving Party or its Affiliate without access to or aid, application or use of
the other Party’s Confidential Information, as evidenced by a contemporaneous writing. 
 As between the Parties, each Party shall own
its Confidential Information. 
 10.2 Authorized Disclosure. Notwithstanding the obligations set forth in Section 10.1, a Party
may disclose the other Party’s Confidential Information and the terms of this Agreement to the extent: 
 (a) such disclosure is
reasonably necessary to its employees, agents, consultants, contractors, licensees or sublicensees on a need-to-know basis for the sole purpose of performing its obligations or exercising its rights under this Agreement; provided that in each case,
the disclosees are bound by written obligations of confidentiality and non-use consistent with those contained in this Agreement; or 

(b) such disclosure is reasonably necessary to any bona fide potential or actual investor, acquiror, merger partner, licensee,
sublicensee, or other financial or commercial partner for the sole purpose of evaluating an actual or potential investment, acquisition or other business relationship; provided that in connection with such disclosure, such Party shall use all
reasonable efforts to inform each disclosee of the confidential nature of such Confidential Information and, in each case, the disclosees are bound by written obligations of confidentiality and non-use consistent with those contained in this
Agreement; or 
 (c) such disclosure is reasonably necessary to comply with applicable Laws, rules or regulations promulgated by
Governmental Authorities or applicable securities exchanges, court order, or administrative subpoena or order; provided that the Party subject to such Laws, rules, regulations, court order, or administrative subpoena or order shall (i) promptly
notify the other Party prior to making such required disclosure; (ii) provide reasonable prior advance notice of the proposed text of such disclosure to the other Party for its prior review; (iii) use good faith efforts to incorporate the
reviewing Party’s reasonable comments thereon and (iv) use reasonable efforts to obtain, or to assist the other Party in obtaining, a protective order preventing or limiting the required disclosure. 

10.3 Technical Publication. Pfenex may not publish peer reviewed manuscripts, or provide other forms of public disclosure including
abstracts and presentations, of results of studies carried out under the Development Plans, or otherwise pertaining to a Product, without the prior written consent of Jazz. Commencing upon (a) the end of the Assessment Period for a HemOnc
Product for which Jazz has not provided a Declination Notice in the case of each HemOnc Product and (b) Option Exercise in the case of the Pegaspargase Product, Jazz shall 

  
 46. 

[***] 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. 








 
have the right to publish and otherwise publicly disclose peer reviewed manuscripts, or provide other forms of public disclosure including abstracts and presentations, of results of studies
carried out by or on behalf of Jazz under the Development Plan for the applicable Product concerning the Development and Commercialization of such Product, including on clinicaltrials.gov, subject to compliance with this Section 10.3. In the
event that Jazz desires to make such a publication or public presentation of a technical nature describing the manufacturing process of a Product, it shall provide Pfenex with at least ten (10) days to review and comment on such proposed
publication or presentation prior to its submission for publication or presentation. Pfenex shall have the right to delay publication or presentation for up to an additional thirty (30) days in order to enable patent applications protecting
each Party’s rights in such Information to be filed, and Pfenex shall also have the right to prohibit the disclosure of any of its Confidential Information contained in any such proposed publication or presentation. In any permitted publication
or presentation by a Party, the other Party’s contribution shall be duly recognized, and co-authorship shall be determined, in accordance with customary standards. 

10.4 Publicity; Term of Agreement. 

(a) The Parties agree that the material terms of this Agreement are the Confidential Information of both Parties, subject to the
special authorized disclosure provisions set forth in this Section 10.4 or Section 10.2. 
 (b) The Parties agree to issue
a joint press release announcing the execution of this Agreement promptly after the Effective Date in the form attached hereto as Exhibit 10.4(b). 

(c) After release of such press release, if either Party desires to make a public announcement concerning the material terms of this
Agreement or any activities hereunder, including announcement of the achievement of milestones under Section 6.3 and the magnitude of payments associated therewith, such Party shall give reasonable prior advance notice (which in any case shall
be at least three (3) Business Days) of the proposed text of such announcement to the other Party for its prior review and approval (which approval shall not be unreasonably withheld, conditioned or delayed) and shall use good faith efforts to
incorporate the other Party’s reasonable comments thereon, except that in the case of a public announcement required by Laws, the disclosing Party shall provide the other Party with such advance notice as it reasonably can and shall not be
required to obtain approval therefor. Notwithstanding the foregoing, (i) Pfenex may not, in any public announcement with respect to this Agreement, [***] without Jazz’s prior written consent and (ii) Jazz may not, in any public
announcement with respect to this Agreement, [***] without providing prior written notice to Pfenex and reasonably coordinating with Pfenex regarding such public announcement. A Party commenting on such a proposed public announcement shall provide
its comments, if any, within three (3) Business Days after receiving the text of the public announcement for review. Neither Party shall be required to seek the permission of the other Party to repeat any information that has already been
publicly disclosed by such Party, or by the other Party, in accordance with this Section 10.4(c), provided such information remains accurate as of such time. 

(d) The Parties acknowledge that either or both Parties may be obligated to file under applicable Laws or rules or regulations
promulgated by Governmental Authorities or applicable securities exchanges a copy of this Agreement with the U.S. Securities and Exchange 

  
 47.

Commission or other Governmental Authorities. In the event that a Party determines in good faith that such a filing is required, such Party shall request confidential treatment of all
confidential information herein, including the sensitive commercial, financial and technical terms hereof, to the extent such confidential treatment may be reasonably available to such Party. In the event of any such filing, the filing Party shall
provide the other Party with a copy of this Agreement marked to show provisions for which such filing Party intends to seek confidential treatment within a reasonable amount of time prior to filing and shall use good faith efforts to incorporate the
other Party’s reasonable comments thereon to the extent consistent with applicable Laws or rules or regulations promulgated by Governmental Authorities or applicable securities exchanges. Each Party shall be responsible for its own legal and
other external costs in connection with any such filing. 
 ARTICLE 11 

TERM AND TERMINATION 

11.1 Term. The term of this Agreement (the “Term”) shall commence on the Effective Date and, unless earlier terminated
pursuant to this Agreement, shall continue on a Product-by-Product basis for so long as such Product is being Developed or Commercialized under and in accordance with this Agreement. 

11.2 Unilateral Termination by Jazz. Jazz may terminate this Agreement, on a Product-by-Product basis or in its entirety, for
any or no reason upon ninety (90) days’ written notice to Pfenex. 
 11.3 Termination by Either Party for Breach. 

 (a) Breach. Subject to Section 11.3(b) and 11.3(c), each Party shall have the right to terminate this Agreement upon written
notice to the other Party in the event such other Party materially breaches this Agreement and, after receiving written notice from the non-breaching Party identifying such material breach in reasonable detail, fails to cure such material breach
within ninety (90) days from the date of such notice; provided that if such breach is not reasonably capable of cure within such time period, the breaching Party may submit a reasonable cure plan prior to the end of such time period, in which
case the other Party shall not have the right to terminate this Agreement for up to an additional ninety (90) days so long as the breaching Party is using Commercially Reasonable Efforts to implement such cure plan. 

(b) Disputed Breach. If the alleged breaching Party disputes in good faith the existence or materiality of a breach specified in a
notice provided by the other Party in accordance with Section 11.3(a), and such alleged breaching Party provides the other Party notice of such dispute within the ninety (90)-day cure period, then the non-breaching Party shall not have the
right to terminate this Agreement under Section 11.3(a) unless and until an arbitrator, in accordance with Article 12, has determined that the alleged breaching Party has materially breached this Agreement and that such Party fails to cure such
breach within ninety (90) days following such arbitrator’s decision. It is understood and agreed that during the pendency of such dispute, all of the terms and conditions of this Agreement shall remain in effect and the Parties shall
continue to perform all of their respective obligations hereunder.

[***] 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. 








 (c) Product-by-Product Termination. If the uncured material breach pertains to less than
all of the Product(s), then termination under this Section 11.3 shall apply only with respect to such Product(s), and the non-breaching Party shall not have the right to terminate this Agreement in its entirety or with respect to the other
Product(s) not affected by such breach. Without limiting the generality of the foregoing, the Parties’ rights and obligations hereunder with respect to the Pegaspargase Product shall not be affected by termination of this Agreement with respect
to one or both HemOnc Products, and the Parties’ rights and obligations hereunder to the HemOnc Products shall not be affected by termination of this Agreement with respect to the Pegaspargase Product. 

11.4 Effects of Unilateral Termination by Jazz. If this Agreement is terminated by Jazz under Section 11.2 in its entirety or with
respect to one or both of the HemOnc Products or the Pegaspargase Product then the following terms shall apply: 
 (a) HemOnc-Pf.

 (i) Prior to Assessment Period Expiry. Upon any notice of termination of HemOnc-Pf delivered prior to the expiration of the
Assessment Period for HemOnc-Pf, Jazz shall have the obligations under this Section 11.4(a)(i). Prior to the effective date of termination, Jazz shall provide Pfenex with access to all HemOnc-Pf data Controlled by Jazz that was generated by
Jazz pursuant to this Agreement (the “Jazz HemOnc-Pf Data”). Pfenex shall have the option, exercisable within thirty (30) days following the delivery of the Jazz HemOnc-Pf Data to Pfenex by Jazz, to notify Jazz whether Pfenex
desires to license (including the right to use and disclose to Third Parties) the Jazz HemOnc-Pf Data on an exclusive basis (subject to the Jazz Retained Data Rights, as defined below) solely for the development, manufacture and commercialization in
the Territory of HemOnc-Pf. Jazz retains exclusive ownership of the Jazz HemOnc-Pf Data and the right to use the Jazz HemOnc-Pf Data for any and all purposes not expressly granted to Pfenex, provided that Jazz shall not disclose the Jazz HemOnc-Pf
Data to any Third Party other than (A) to Third Party collaborators for any product other than HemOnc-Pf (provided that all such Third Party collaborators are subject to (x) confidentiality obligations consistent with those contained in
this Agreement and (y) use restrictions that limit such Third Party collaborators’ use of the Jazz HemOnc-Pf Data solely to the purposes of the collaboration and exclude any use with respect to HemOnc-Pf), (B) to any Regulatory
Authority to the extent required to comply with applicable Laws or where requested by Regulatory Authorities, in which case Jazz shall promptly notify Pfenex of such requirement under applicable Laws and, to the extent practicable and permitted
under applicable Laws, shall submit any proposed communication to Pfenex for prior approval (such approval not to be unreasonably withheld, conditioned, or delayed) or, if not practicable or permitted, shall provide Pfenex with a copy or summary
thereof as soon as reasonably practicable thereafter, and (C) to any Governmental Authority as reasonably necessary in connection with the prosecution or maintenance of any Jazz Sole Patent or Joint Patent (the “Jazz Retained Data
Rights”). If Pfenex elects to license the Jazz HemOnc-Pf Data, Pfenex shall pay Jazz for Pfenex’s license to the Jazz HemOnc-Pf Data in an amount equal to [***], to be paid by Pfenex to Jazz in semi-annual installments over the
immediate three (3)-year period following the effective date of termination, and Pfenex shall be bound by the indemnification and insurance provisions set forth on Exhibit 11.4(a)(i). If Pfenex fails to timely pay Jazz any
of the foregoing payments within thirty (30) days following written notice from Jazz to Pfenex of such payment default, Pfenex’s 

  
 49. 

[***] 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. 








 
license to the Jazz HemOnc-Pf Data will immediately terminate. In the event of a termination of this Agreement with respect to all HemOnc Products, Pfenex shall have the right to license the
applicable data generated on a HemOnc Product-by-HemOnc Product basis, provided that Pfenex pays the amount set forth in Section 11.4 with respect to each such HemOnc Product for which such data is licensed. 

(ii) Following Assessment Period Expiry. Upon any notice of termination of HemOnc-Pf delivered following the expiration of the
Assessment Period for HemOnc-Pf, Jazz shall have the obligations under this Section 11.4(a)(ii). 
 (A) Prior to the effective
date of termination, Jazz shall provide Pfenex with access to the Jazz HemOnc-Pf Data. Pfenex shall have the option, exercisable within thirty (30) days following the delivery of the Jazz HemOnc-Pf Data to Pfenex by Jazz, to notify Jazz whether
Pfenex desires to license (including the right to use and disclose to Third Parties) the Jazz HemOnc-Pf Data on an exclusive basis (subject to the Jazz Retained Data Rights) solely for the development, manufacture and commercialization in the
Territory of HemOnc-Pf. If Pfenex elects to license the Jazz HemOnc-Pf Data, Pfenex shall pay Jazz for Pfenex’s license to the Jazz HemOnc-Pf Data in an amount equal to [***], to be paid by Pfenex to Jazz in semi-annual installments over the
immediate three (3)-year period following the effective date of termination, and Pfenex shall be bound by the indemnification and insurance provisions set forth on Exhibit 11.4(a)(i). If Pfenex fails to timely pay Jazz any
of the foregoing payments within thirty (30) days following written notice from Jazz to Pfenex of such payment default, Pfenex’s license to the Jazz HemOnc-Pf Data will immediately terminate. 

(B) If, at the time of such termination, Jazz is then clinically developing a product containing [***] (such product, the
“Alternative Product”) and Pfenex elected to license the Jazz HemOnc-Pf Data under subsection (A) above, then Jazz will pay to Pfenex a royalty of [***] of net sales of such Alternative Product for the shorter of (x) a
period equal to the sum of six (6) months plus the number of months that, as of the termination, the Alternative Product is ahead of the development of HemOnc-Pf under this Agreement or (y) five (5) years from first commercial sale of
such Alternative Product anywhere in the world. For purposes of Section 11.4(a)(ii)(B)(x), “ahead” means a reasonable estimate of the number of months that it would have taken HemOnc-Pf, following the effective date of termination, to
attain a comparable stage of development as such Alternative Product (taking into account the relevant regulatory and technical differences, if any) as of the effective date of termination, as agreed by the Parties in writing after good faith
negotiation, subject to resolution by baseball arbitration pursuant to Section 12.2(b) if the Parties are unable to agree upon such estimated number of months within sixty (60) days after the effective date of termination. For purposes of
such royalty, the terms “net sales” and “first commercial sale” with respect to such Alternative Product shall have the same meanings as “Net Sales” and “First Commercial Sale,” respectively, under this
Agreement, and such royalty shall be paid in accordance with Sections 6.5(d), 6.7, 6.8, 6.9 and 6.10, in each case mutatis mutandis. The obligation to make such royalty payments to Pfenex is conditioned upon Pfenex meeting its payment
obligation under subsection (A) above and shall continue for the stated period only for so long as Pfenex is using Commercially Reasonable Efforts to continue the development and commercialization of the terminated HemOnc-Pf product. Pfenex
shall provide Jazz with semi-annual reports with respect to such continued development and commercialization and notify Jazz if such development or 

  
 50. 

[***] 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. 








 
commercialization is discontinued for more than a three (3)-month period. Jazz shall have the right to set off from any such royalty an amount equal to the development costs owed and not yet paid
by Pfenex under subsection (A) above. 
 (iii) Election Not to License Jazz HemOnc-Pf Data. If Pfenex elects not to license the
Jazz HemOnc-Pf Data, then it shall immediately return or destroy the Jazz HemOnc-Pf Data, at Jazz’s option, and Pfenex may not use the Jazz HemOnc-Pf Data for any purpose. Further, if Pfenex elects not to license the Jazz HemOnc-Pf Data and the
termination of HemOnc-Pf occurs after commencement of the Assessment Period for HemOnc-Pf but before the earlier of (A) twelve (12) months after the expiration of such Assessment Period or (B) payment of milestone 3 in Exhibit
6.3 for HemOnc-Pf, then Jazz shall pay to Pfenex the amount of [***] within thirty (30) days following notice of such election by Pfenex. 

(b) HemOnc-NextGen. 

(i) Access to Data. Upon any notice of termination of HemOnc-NextGen, Jazz shall have the obligations under this
Section 11.4(b). Prior to the effective date of termination, Jazz shall provide Pfenex with access to all HemOnc-NextGen data Controlled by Jazz that was generated by Jazz pursuant to this Agreement (the “Jazz HemOnc-NextGen
Data”). For clarity, the Jazz HemOnc-NextGen Data excludes the Jazz Extension IP. Pfenex shall have the option, exercisable within thirty (30) days following the delivery of the Jazz HemOnc-NextGen Data to Pfenex by Jazz (which period
may be extended by Pfenex as reasonably necessary (not to exceed an additional ninety (90) days) for Pfenex to negotiate a direct license from any Third Party that Controls the intellectual property claiming the Half-Life Extension Component
included in HemOnc-NextGen, as described below), to license (including the right to use and disclose to Third Parties) the Jazz HemOnc-NextGen Data on an exclusive basis (subject to the Jazz Retained Data Rights, as applied mutatis mutandis
with respect to the Jazz HemOnc-NextGen Data) solely for the development, manufacture and commercialization in the Territory of HemOnc-NextGen. Upon Pfenex’s exercise of such option with respect to the Jazz HemOnc-NextGen Data, Jazz shall
negotiate in good faith with Pfenex, for a period of no more than sixty (60) days or such longer period as mutually agreed by the Parties, the payment terms and conditions for such license, subject to Section 11.4(b)(ii) below. Any license
granted under this Section 11.4(b)(i) shall also be subject to the indemnification and insurance provisions set forth on Exhibit 11.4(a)(i). In connection with Pfenex’s exercise of such option with respect to the Jazz
HemOnc-NextGen Data, Pfenex may notify Jazz that it desires to obtain rights to the Jazz Extension IP. Upon such notification and concurrently with the negotiation of a definitive agreement for the Jazz HemOnc-NextGen Data, Jazz shall negotiate in
good faith with Pfenex to include in such definitive agreement an exclusive license to that portion of the Jazz Extension IP that is owned by Jazz solely as to the development, manufacture, and commercialization in the Territory of HemOnc-NextGen,
subject to Section 11.4(b)(ii) below. In addition, Pfenex shall use good faith and reasonable efforts to obtain a direct license from any Third Party that Controls the intellectual property claiming the Half-Life Extension Component included in
HemOnc-NextGen, and upon Pfenex’s request, Jazz shall facilitate an introduction of Pfenex to such Third Party. To the extent that Pfenex is unable to obtain such a license from such Third Party after using such good faith and reasonable
efforts, Jazz shall, to the extent permitted under its license agreement with such Third Party, either assign or license (in Jazz’s sole discretion) to Pfenex its right, title, and interest in and to such Third Party license agreement, to the
extent necessary for 

  
 51. 

[***] 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. 








 
Pfenex to Develop, manufacture and Commercialize HemOnc-NextGen in the Territory. Pfenex shall reimburse Jazz for any amounts payable by Jazz to any Third Party in connection with such assignment
of or license to such Third Party license agreement, and Pfenex shall not owe Jazz any additional consideration in connection with Pfenex’s practice of such license. 

(ii) Payment Terms. 

(A) Prior to Expiry of Assessment Period. If such termination with respect to HemOnc-NextGen occurs prior to the expiration of
the Assessment Period for HemOnc-NextGen, the payment terms of such license to the Jazz HemOnc-NextGen Data shall be limited to Pfenex paying Jazz for Pfenex’s license to such data in an amount equal to [***], which amounts shall be paid by
Pfenex to Jazz in semi-annual installments over the immediate three (3)-year period following the effective date of termination. If Pfenex fails to timely pay Jazz any of the foregoing payments within thirty (30) days following written notice
from Jazz to Pfenex of such payment default, Pfenex’s license to such data will immediately terminate. 
 (B) Following Expiry of
Assessment Period. If such termination with respect to HemOnc-NextGen occurs after the expiration of the Assessment Period for HemOnc-NextGen, the payment terms of such license to the Jazz HemOnc-NextGen Data shall be negotiated in good
faith as set forth in Section 11.4(b)(i). If the Parties are unable to agree on such payment terms and execute an agreement with respect to the Jazz HemOnc-NextGen Data during such sixty (60) day negotiation period, Pfenex shall have the
right to have such payment terms determined by baseball arbitration pursuant to Section 12.2(b). 
 (C) Election Not to License
Jazz HemOnc-NextGen Data. If Pfenex elects not to license the Jazz HemOnc-NextGen Data, then it shall immediately return or destroy such data, at Jazz’s option, and Pfenex may not use the Jazz HemOnc-NextGen Data for any purpose. Further,
if Pfenex elects not to license the Jazz HemOnc-NextGen Data and the termination of HemOnc-NextGen occurs after commencement of the Assessment Period for HemOnc-NextGen but before the earlier of (A) twelve (12) months after the expiration
of such Assessment Period or (B) payment of milestone 3 in Exhibit 6.3 for HemOnc-NextGen, then Jazz shall pay to Pfenex the amount of [***] within thirty (30) days following Pfenex’s election notice or within thirty
(30) days of the expiration or early termination of the negotiation period, as applicable. 
 (c) Pegaspargase Product. If Jazz
terminates its rights hereunder with respect to the Pegaspargase Product prior to Option Exercise, then the Option shall terminate and the Parties’ obligations under this Agreement with respect to the Pegaspargase Product shall terminate. 

11.5 Effects of Other Termination. 

(a) General. Upon any termination of this Agreement in its entirety (i.e., with respect to all Products) or in part (i.e., with respect
to one or more, but not all, Products), the licenses and other rights and obligations under of this Agreement applicable to the terminated Product(s) shall terminate, except for the licenses granted in Section 7.1(f), which shall survive any
termination. 

  
 52. 

[***] 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. 








 (b) Termination by Jazz for Pfenex’s Breach. If Jazz terminates this Agreement in its
entirety or for a Product on account of Pfenex’s uncured material breach with respect to a particular Product, then Pfenex will not have any rights with respect to any data generated by Jazz with respect to any terminated Product(s) (or all of
the Products if this Agreement is terminated in its entirety), and Jazz will have no further obligation to Pfenex with respect to any such terminated Product(s) under this Section 11.5. 

(c) Termination by Pfenex for Jazz’s Breach. With respect to termination by Pfenex of this Agreement for one or more Products on
account of Jazz’s uncured material breach with respect to such Product(s): 
 (i) if Pfenex terminates with respect to
HemOnc-Pf prior to the expiry of the Assessment Period for HemOnc-Pf, then Section 11.4(a)(i) applies; 
 (ii) if Pfenex
terminates with respect to HemOnc-Pf following the expiry of the Assessment Period for HemOnc-Pf, then Section 11.4(a)(ii) applies; 

(iii) if Pfenex terminates with respect to HemOnc-NextGen prior to the expiry of the Assessment Period for HemOnc-NextGen, then
Sections 11.4(b)(i) and 11.4(b)(ii)(A) apply; 
 (iv) if Pfenex terminates with respect to HemOnc-NextGen following the expiry of
the Assessment Period for HemOnc-NextGen, then Sections 11.4(b)(i) and 11.4(b)(ii)(B) apply; 
 (v) if Pfenex terminates with
respect to the Pegaspargase Product, then Section 11.4(c) applies; 
 in each instance of the above, with the same effect as if Jazz had terminated
this Agreement with respect to such Product pursuant to Section 11.2. 
 (d) Termination of All Products. For clarity, if this
Agreement has been terminated on a Product-by-Product basis such that all Products have been terminated, then this Agreement thereupon shall be deemed to have been terminated in its entirety and the ROFN thereupon shall be deemed to have terminated
with respect to all ROFN Products, except with respect to any ROFN Exercise (and subject to the terms and conditions of the corresponding ROFN Exercise Agreement) that may have occurred prior to the effective date of such termination of this
Agreement. 
 11.6 Survival. Termination or expiration of this Agreement shall not affect any rights or obligations of the Parties
under this Agreement that have accrued prior to the date of termination or expiration. Notwithstanding anything to the contrary, the following provisions shall survive any expiration or termination of this Agreement: Article 1 (to the extent defined
terms are contained in the following surviving Articles and Sections), Section 2.3, Section 4.5, Section 6.9, Article 6 (solely with respect to those payments that accrued prior to the effective date of termination or expiration),
Section 7.1, Section 8.4, Article 9 (with respect to any matter, fact or circumstance arising or existing prior to the termination or expiration of this Agreement), Article 10, this Section 11.6, Article 12 and Sections 13.3, 13.4,
13.5, and 13.12.

 ARTICLE 12 

DISPUTE RESOLUTION 

12.1 Disputes. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this
Agreement in an expedient manner by mutual cooperation and without resort to litigation. In the event of any disputes, controversies or differences which may arise between the Parties out of or in relation to or in connection with this Agreement
(other than disputes arising from the JDC, which shall be resolved in accordance with Section 3.3), including any alleged failure to perform, or breach, of this Agreement, or any issue relating to the interpretation or application of this
Agreement (each, a “Dispute”), then upon the request of either Party by written notice, the Parties agree to meet and discuss in good faith a possible resolution thereof, which good faith efforts shall include at least one in-person
meeting (or telephone call if an in-person meeting is impractical) between the Parties’ respective Executive Officers. If the matter is not resolved within thirty (30) days following the written request for discussions, either Party may
then invoke the provisions of Section 12.2. 
 12.2 Arbitration. 

(a) JAMS. Any Dispute that is not resolved pursuant to Section 12.1, except for a dispute, claim or controversy under
Section 12.9, shall be settled by binding arbitration administered by JAMS before one arbitrator pursuant to the Streamlined Arbitration Rules and Procedures of JAMS then in effect (the “JAMS Rules”), except as otherwise
provided herein. The arbitration shall be governed by the U.S. Federal Arbitration Act, 9 U.S.C. §§ 1-16 (the “Federal Arbitration Act”), to the exclusion of any inconsistent state laws. The arbitration will be conducted
in Los Angeles, California, and the Parties consent to the personal jurisdiction of the U.S. federal courts, for any case arising out of or otherwise related to this arbitration, its conduct and its enforcement. The language to be used in the
arbitral proceedings will be English. 
 (b) Baseball Arbitration. This Section 12.2(b) shall apply to Disputes identified under
Sections 2.4(e), 2.5(c)(i), 11.4(a)(ii)(B) and 11.4(b)(ii)(B) as to be resolved by baseball arbitration. Baseball arbitration will be conducted by one (1) arbitrator who shall be reasonably acceptable to the Parties and who shall be appointed
in accordance with JAMS Rules. If the Parties are unable to select an arbitrator within ten (10) days, then the arbitrator shall be appointed in accordance with JAMS Rules. Any arbitrator chosen hereunder shall have educational training and
industry experience sufficient to demonstrate a reasonable level of scientific, financial, medical and industry knowledge relevant to the Dispute. Within twenty (20) days after the selection of the arbitrator, each Party shall submit to the
arbitrator and the other Party a proposed resolution of the Dispute that is the subject of the arbitration, together with any relevant evidence in support thereof (the “Proposals”). Within fifteen (15) days after the delivery
of the last Proposal to the arbitrator, each Party may submit a written rebuttal of the other Party’s Proposal and may also amend and re-submit its original Proposal. The Parties and the arbitrator shall meet within fifteen (15) days after
the Parties have submitted their final Proposals (and rebuttals, if any), at which time each Party shall have one (1) hour to argue in support of its Proposal. The Parties shall not have the right to call any witnesses in support of their
arguments, nor compel any production of documents or take any discovery from the other Party in preparation for the meeting. Within thirty (30) days after such meeting, the arbitrator shall select one of the final Proposals so submitted by one
of the Parties as the resolution of the 

  
 54. 

[***] 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. 








 
Dispute, but may not alter the terms of either final Proposal and may not resolve the Dispute in a manner other than by selection of one of the submitted final Proposals. If a Party fails to
submit a Proposal within the initial twenty (20)-day time frame set forth above, the arbitrator shall select the Proposal of the other Party as the resolution of the Dispute. 

12.3 Governing Law. Resolution of all Disputes and any remedies relating thereto, shall be governed by and construed under the
substantive laws of the State of California, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. 

12.4 Award. Any award shall be promptly paid in Dollars free of any tax, deduction or offset; and any costs, fees or taxes incident to
enforcing the award shall, to the maximum extent permitted by law, be charged against the Party resisting enforcement. If as to any issue the arbitrator should determine under the applicable law that the position taken by a Party is frivolous or
otherwise irresponsible or that any wrongdoing it finds is in callous disregard of law and equity or the rights of the other Party, the arbitrator shall also be entitled to award an appropriate allocation of the adversary’s reasonable attorney
fees, costs and expenses to be paid by the offending Party, the precise sums to be determined after a bill of attorney fees, expenses and costs consistent with such award has been presented following the award on the merits. Each Party agrees to
abide by the award rendered in any arbitration conducted pursuant to this Article 12, and agrees that, subject to the Federal Arbitration Act, judgment may be entered upon the final award in the Federal District Court in the Central District of
California and that other courts may award full faith and credit to such judgment in order to enforce such award. The award shall include interest from the date of any damages incurred for breach of this Agreement, and from the date of the award
until paid in full, at a rate fixed by the arbitrator. 
 12.5 Costs. Except as set forth in Section 12.4, each Party shall bear
its own legal fees. The arbitrator shall assess his or her costs, fees and expenses against the Party losing the arbitration unless he or she believes that neither Party is the clear winner, in which case the arbitrator shall divide his or her fees,
costs and expenses according to his or her sole discretion. 
 12.6 Injunctive Relief. Provided a Party has made a sufficient showing
under the rules and standards set forth in the U.S. Federal Rules of Civil Procedure and applicable case law, the arbitrator shall have the freedom to invoke, and the Parties agree to abide by, injunctive measures after either Party submits in
writing for arbitration claims requiring immediate relief. Additionally, nothing in this Article 12 will preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a
temporary restraining order, preliminary injunction or other interim equitable relief, concerning a Dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the
arbitration proceeding. 
 12.7 Confidentiality. The arbitration proceeding shall be confidential and the arbitrator shall
issue appropriate protective orders to safeguard each Party’s Confidential Information. Except as required by law, no Party shall make (or instruct the arbitrator to make) any public announcement with respect to the proceedings or decision of
the arbitrator without prior written consent of the other Party. The existence of any Dispute submitted to arbitration, 

  
 55. 

[***] 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. 








 
and the award, shall be kept in confidence by the Parties and the arbitrator, except as required in connection with the enforcement of such award or as otherwise required by applicable Laws. 

12.8 Survivability. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this
Agreement for any reason. 
 12.9 Patent and Trademark Disputes. Any dispute, controversy or claim relating to the scope, validity,
enforceability or infringement of any patents or trademarks covering the manufacture, use, importation, offer for sale or sale of a Product shall be submitted to a court of competent jurisdiction in the country in which such patent or trademark
rights were granted or arose. 
 12.10 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL,
CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY (WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE) STRICT LIABILITY OR OTHERWISE), REGARDLESS
OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 12.10 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 9.1 OR 9.2 OR DAMAGES
AVAILABLE FOR BREACH OF ARTICLE 10. 
 ARTICLE 13 

MISCELLANEOUS 
 13.1
Entire Agreement; Amendment. This Agreement, including the Exhibits hereto, sets forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between
the Parties hereto with respect to the subject matter hereof and supersedes, as of the Effective Date, all prior and contemporaneous agreements and understandings between the Parties with respect to the subject matter hereof, including the
Confidentiality Agreements. The foregoing shall not be interpreted as a waiver of any remedies available to either Party as a result of any breach, prior to the Effective Date, by the other Party of its obligations under the Confidentiality
Agreements. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as are set forth in this Agreement. No subsequent alteration, amendment,
change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party. 

13.2 Rights in Bankruptcy. 

(a) 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 

  
 56. 

[***] 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. 








 
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. 

(b) 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. 
 (c) 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. 
 (d) 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. 
 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, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe, and failure of
plant or

machinery (provided that such failure could not have been prevented by the exercise of skill, diligence, and prudence that would be reasonably and ordinarily expected from a skilled and
experienced person engaged in the same type of undertaking under the same or similar circumstances). 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. 

13.4 Notices. Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this
Agreement, and shall be addressed to the appropriate Party at the address specified below or such other address as may be specified by such Party in writing in accordance with this Section 13.4, and shall be deemed to have been given for all
purposes (a) when received, if hand-delivered or sent by confirmed facsimile or a reputable courier service, or (b) five (5) Business Days after mailing, if mailed by first class certified or registered airmail, postage prepaid,
return receipt requested.

 13.5 No Strict Construction; Headings. This Agreement has been prepared jointly by the
Parties and shall not be strictly construed against either Party. Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision. The headings of
each Article and Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section. Except where the context otherwise
requires, the use of any gender shall be applicable to all genders, and the word “or” is used in the inclusive sense (and/or). The term “including” as used herein means including, without limiting the generality of any
description preceding such term. 
 13.6 Assignment. Neither Party may assign or transfer this Agreement or any rights or obligations
hereunder without the prior written consent of the other, except that a Party may make such an assignment or transfer without the other Party’s consent to (a) its Affiliates (provided that, if Pfenex is the assigning Party, Pfenex (or its
successor) guarantees such Affiliate’s performance of its obligations under this Agreement or obtains Jazz’s consent for such assignment notwithstanding the foregoing); or (b) a Third Party successor to all or substantially all of the
business of such Party to which this Agreement relates, whether in a merger, sale of stock, sale of assets or other Change of Control transaction. Any successor or assignee of rights and/or obligations permitted hereunder shall, in writing to the
other Party, expressly assume performance of such rights and/or obligations. Any permitted assignment shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this
Section 13.6 shall be null, void and of no legal effect.  
 13.7 Change of Control. Each Party (the “Acquired
Party”) shall, to the extent such Party is not required to publicly disclose a Change of Control, notify the other Party in writing within one (1) Business Day after entering into any agreement providing for or intended to result in
any Change of Control of the Acquired Party, identifying the parties to such agreement, and shall provide such notice where possible at least thirty (30) days prior to the effectiveness of such Change of Control. Following the effectiveness of
such Change of Control, such other Party shall have the right to disband the JDC and to require the Acquired Party, including the acquiring party in such Change of Control, to adopt reasonable procedures to be agreed upon in writing with such other
Party to limit the dissemination of such other Party’s Confidential Information to only those personnel having a need to know such Confidential Information in order for the Acquired Party to perform its obligations or to exercise its rights
under this Agreement and to prohibit and limit the use and disclosure of Confidential Information for competitive reasons against such other Party and its Affiliates; provided, however, that in the case of a Change of Control of Jazz, Pfenex may not
disband the JDC prior to the Manufacturing Process Transfer under Section 4.7. 
 13.8 Performance by Affiliates. Each Party may
discharge any obligations and exercise any right hereunder through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to comply
with the provisions of this Agreement in connection with such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed
directly against such Party without any obligation to first proceed against such Party’s Affiliate. 

  
 59.

 13.9 Further Actions. Each Party agrees to execute, acknowledge and deliver such further
instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement. 

13.10 Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of
competent jurisdiction from which no appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace
any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized. 

13.11 No Waiver. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other
matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period of
time. 
 13.12 Independent Contractors. Each Party shall act solely as an independent contractor, and nothing in this Agreement shall
be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way. Nothing herein shall be construed to create the relationship of partners, principal and agent, or joint-venture partners between the
Parties. 
 13.13 Counterparts. This Agreement may be executed in one (1) or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. Executed counterpart signature pages delivered via facsimile or similar electronic transmission in .PDF or similar format shall be deemed binding as originals. 

13.14 Remedies Non-Exclusive and Cumulative. Unless expressly stated otherwise in this Agreement, all remedies provided for in this
Agreement shall be cumulative and in addition to, and not in lieu of, any other remedies available to either Party at law, in equity, or otherwise in accordance with the terms of this Agreement, including any claim for breach of this Agreement.
Nothing in this Agreement shall be interpreted as limiting either Party’s rights to pursue any remedies for breach of contract of this Agreement, except as expressly stated otherwise in this Agreement.

 Jazz Pharmaceuticals and Pfenex Enter into a Worldwide License and Option Agreement Related to Product
Candidates in Early Development for Hematological Malignancies 
 DUBLIN and SAN DIEGO July 28, 2016 — Jazz Pharmaceuticals plc (Nasdaq: JAZZ)
and Pfenex Inc. (NYSE MKT: PFNX) today announced an agreement under which Pfenex granted Jazz Pharmaceuticals worldwide rights to develop and commercialize multiple early stage hematology product candidates. The agreement also includes an option for
Jazz Pharmaceuticals to negotiate a license for a recombinant pegaspargase product candidate with Pfenex. This early development stage collaboration demonstrates Jazz Pharmaceuticals’ focus on identifying innovative technologies that may lead
to the development of important therapeutic options for patients with hematological malignancies. 
 Under the agreement, Pfenex will receive upfront and
option payments totaling $15 million and may be eligible to receive additional payments of up to $166 million based on the achievement of certain development-, regulatory-, and sales-related milestones, including up to $41 million for certain
non-sales-related milestones. Pfenex may also be eligible to receive tiered royalties on worldwide sales of any products resulting from the collaboration. Both parties will be contributing to development efforts. 

“The collaboration with Pfenex, including access to its unique protein expression technology, demonstrates our emphasis on diversifying and
strengthening our portfolio to provide improved therapeutic options for patients.” said Karen Smith M.D., Ph.D, global head of research and development and chief medical officer at Jazz Pharmaceuticals plc. “We look forward to working with
