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 
  

[***] 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. 

  
 14. 













 
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 (subject to the final sentence of Section 4.7(a)). 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 the date of
receipt of notice. If Jazz does not provide Pfenex with a Declination Notice during the Assessment Period with respect to either HemOnc Product, Jazz will retain its license hereunder and be obligated to commence its obligations with respect to such
HemOnc Product, and such HemOnc Product will remain a Product for the purposes of this Agreement. [***]. 

(b)    License to Jazz. Pfenex hereby grants Jazz an exclusive (even as to Pfenex except as provided in
Section 2.1(c) below), royalty-bearing and sublicenseable (subject to Section 2.1(d)) license, under the Pfenex IP to research, Develop, make, have made, use, sell, have sold, offer for sale, import, and otherwise Commercialize the HemOnc
Products in the Field in the Territory. 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) or 13.2(c)(ii), 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

 15. 













 
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

 16. 













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

(c)    Option Exercise. Jazz may exercise the Option by providing written notice (an “Option Exercise
Notice”) to Pfenex either: 
 (i)    during the twenty-five (25) Business Day period commencing
upon Jazz’s receipt of Option Data Package 1; or 
 (ii)    to the extent that an Option Exercise Notice has
not previously been delivered by Jazz to Pfenex in connection with Option Data Package 1 or if Jazz delivered an Option Exercise Notice but the Parties were unable to negotiate and enter into an Option Exercise Agreement pursuant to
Section 2.4(d), during the twenty-five (25) Business Day period commencing upon Jazz’s receipt of Option Data Package 2. 
 If Jazz does not
provide an Option Exercise Notice before the expiration of the period referenced in subsection (ii) above, then the Option shall lapse for the Pegaspargase Product and this Agreement shall be deemed terminated with respect to the Pegaspargase
Product, and Pfenex may decide, in its sole discretion, whether to terminate or continue the Development and Commercialization of the Pegaspargase Product, itself or in collaboration with one or more Third Parties, and the terms of
Section 2.6(c)(iii) shall apply with respect to such Product. 
 (d)    Negotiation. Following
Jazz’s delivery of an Option Exercise Notice, the Parties shall use good faith efforts to negotiate the terms and conditions of a definitive agreement regarding the Pegaspargase Product (an “Option Exercise Agreement”) on an
exclusive basis, meaning that Pfenex and its representatives shall not engage in discussions with any Third Party regarding a potential grant of rights to such Third Party with respect to the Pegaspargase Product during the negotiation period. The
terms of such Option Exercise Agreement shall be commercially reasonable and all applicable non-financial terms and conditions shall be substantially the same as those in this Agreement, including
decision-making, diligence, exclusivity (as applicable to the Pegaspargase Product), development, commercialization, manufacture, rights and obligations of the Parties, risk-allocation, intellectual property-related matters, dispute resolution, and
general agreement structure, but excluding any rights of first negotiation or other rights except solely with respect to the Pegaspargase Product. Notwithstanding the foregoing, under the Option Exercise Agreement, Pfenex may opt-in to contribute to the Development costs of the Pegaspargase Product, and upon such opt-in, shall be responsible for between [***] and [***] of the Development costs in
Pfenex’s discretion. The Option Exercise Agreement will also set forth usual and customary economic terms similar to those of this Agreement, including an upfront payment, clinical developmental and commercial milestone payments, and royalty
payments, which payments shall take into account Pfenex’s level of contribution to the Development costs of the Pegaspargase Product. Without limiting the foregoing, the economic terms of the Option Exercise Agreement will reflect the level of
development or commercial funding and risk assumed by each Party (taking into account Pfenex’s investment and risk prior to the Option Exercise Notice) and include the period over which royalties would be paid, as well as applicable deductions
from royalty payments based upon royalty stacking for third party intellectual property (substantially the same as Section 6.5(c) herein) and generic competition. 
  

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

 17. 













 (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 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

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 

 
 [***] Certain information in this document has been omitted and filed separately with

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

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. 

2.6    Exclusivity. 

(a)    Pfenex. Subject to the terms of this Section 2.6, during the Term, Pfenex shall not research,

product), any product containing [***] for such product; (iii) Development, manufacture and Commercialization of HemOnc-Pf under this Agreement, HemOnc-NextGen under this Agreement, if Jazz exercises the
Option, the Pegaspargase Product in accordance with the Option Exercise Agreement, or if Jazz exercises its ROFN for a particular ROFN Product, such ROFN Product in accordance with the applicable ROFN Exercise Agreement and (iv) as provided in
subsection(e) below. 
 (c) Termination of Exclusivity. The exclusivity obligations set forth in Section 2.6(a) and
(b) shall terminate as follows:

HemOnc-Pf, the exclusivity obligations 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

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.

other matters are expressly excluded. In no event shall the JDC have the right to amend, modify, or waive compliance with this Agreement. 

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

(c) Meetings. The JDC shall meet at least two (2) times per calendar year, unless the Parties mutually agree in writing to a
different frequency for such meetings. Either Party may also call a special meeting of the JDC (by videoconference or teleconference) by at least ten (10) Business Days’ prior written notice to the other Party, and such Party shall provide
the JDC, no later than ten (10) Business Days prior to the special meeting, with materials reasonably adequate to enable informed discussion or decision-making, as applicable. No later than ten (10) Business Days prior to any meeting of
the JDC, the chairperson of the JDC shall prepare and circulate an agenda for such meeting; provided, however, that either Party may propose additional topics to be included on such agenda, either prior to or in the course of such meeting. The JDC

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

(a) Formation. Promptly, and in any event within thirty (30) days after the Effective Date, the Parties shall establish a
joint management team (the “Joint Management Team” or “JMT”) and such JMT will: 
 (i) Manage and
coordinate the strategic relationship of the Parties in the performance of the obligations under this Agreement; and 
 (ii) Address
and resolve any disputes of the JDC. 
 (b) Members. Each Party shall appoint one senior executive to the JMT. Each Party may
replace its representative at any time upon written notice to the other Party; provided that each representative shall be an executive of the applicable Party or its Affiliate having sufficient experience and responsibility within such Party to make
decisions arising within the scope of the JMT’s responsibilities. 
 (c) Meetings. The JMT shall meet at least one
(1) time per calendar year. Either Party may also call a special meeting of the JMT (by videoconference or teleconference) by at least ten (10) Business Days’ prior written notice to the other Party, and such Party shall provide the
other member, no later than ten (10) Business Days prior to the special meeting, with materials reasonably adequate to enable informed discussion or decision-making, as applicable. The JMT may meet in person, by videoconference or by
teleconference, as the Parties agree. Each Party shall bear the expense of its respective JMT members’ participation in JMT meetings. Meetings of the JMT shall be effective only if both representatives are present or participating in such
meeting. 
 3.3 Decision Making. The JDC and JMT each shall strive to act by consensus. The representatives from each Party on
the JDC will have, collectively, one (1) vote on behalf of that Party; each Party will have one vote on the JMT. If the JDC is unable to reach consensus on any matter within the JDC’s authority within thirty (30) days after first
considering such matter, then such matter shall be referred to the JMT for resolution. If the JMT, after good faith efforts and consideration of the other party’s position, cannot resolve such matter within thirty (30) days after such
matter has been referred to the JMT, then: 
 (a) Jazz shall have the final decision making authority with respect to all matters
relating to the HemOnc Products; provided that such final decision making authority shall not apply with respect to (i) the prosecution and enforcement of Pfenex Patents (for which 

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

  
 23.

(b) prior to Option Exercise, Pfenex shall have the final decision making authority with respect to all matters relating to the
development of the Pegaspargase Product; provided that Pfenex may not materially change any of its development obligations outlined in the applicable Development Plan with respect to the Pegaspargase Product without Jazz’s prior written
consent; and 
 (c) prior to ROFN Exercise with respect to the applicable ROFN Product, Pfenex shall have the final decision making
authority with respect to all matters relating to the development of such ROFN Product. 
 Notwithstanding the foregoing, a Party may not
exercise such final decision making authority in a manner that would increase the financial obligations of the other Party. For clarity, the JDC and JMT have no authority to determine, and neither Party may exercise final-decision making authority
to resolve, the achievement of a milestone set forth on Exhibit 6.3 or the allocation of responsibility for any delay in achievement thereof. 

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

 (a) Within two (2) Business Days after the Effective Date, Jazz shall pay to Pfenex a one-time, non-refundable (i) upfront payment of [***] Dollars ($[***]) in consideration of the licenses and related rights granted under this Agreement for
HemOnc-NextGen; and (ii) option payment of [***] Dollars ($[***]) in consideration of the Option granted under Section 2.4. The Parties acknowledge and agree that Jazz paid to Pfenex fifteen million Dollars ($15,000,000) pursuant to this
Section 6.1(a) under the Original Agreement. 
 (b) Within ten (10) Business Days after the Amendment Effective Date, Jazz
shall pay to Pfenex a one-time, non-refundable payment of five million Dollars ($5,000,000) in consideration of the amendment and restatement of this Agreement. 

6.2 Development Costs. 

(a) General. Except as expressly set forth herein, each Party shall be responsible for the cost and expenses it incurs to carry
out the Development work under the Development Plans, including in the case of Pfenex, the cost and expense of the manufacturing technology transfer under Section 4.7(b). 

(b) HemOnc Products. If Pfenex is required to perform any Development activities for the HemOnc Products under the applicable
Development Plan or at Jazz’s request, the Parties shall promptly agree on a budget for such activities either in the applicable Development Plan or otherwise prior to the commencement of the applicable activity. 

(i) If Pfenex engages a Third Party to perform such activities because Pfenex does not have the capability to perform such Development
activities, then Jazz shall reimburse Pfenex for its reasonable and documented actual expenses paid by Pfenex to Third Parties to perform such Development activities, without markup, to the extent such expenses do

the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 

  
 31. 













 
not exceed a mutually agreed written budget for such activities or an amount otherwise approved in advance and in writing by Jazz. Within five (5) Business Days after the end of each month
during which Pfenex incurred any such expenses, Pfenex shall provide Jazz with a good faith estimate of all amounts paid to Third Parties in such month, without markup, to engage such Third Party to conduct such Development activities. Within thirty
(30) days after the end of each month during which Pfenex incurred any such expenses, Pfenex shall provide Jazz with an invoice and reasonable supporting documentation for all amounts paid to Third Parties in such month, without markup, to
engage such Third Party to conduct such Development activities (up to the amount budgeted for such Development activities or otherwise approved in writing by Jazz). Jazz shall pay each such invoice within forty-five (45) days after receipt
thereof, except to the extent disputed by Jazz in good faith. Jazz shall notify Pfenex if it disputes any portion of any such invoice prior to the due date for payment. For clarity, Jazz shall not be required to pay any invoiced amount for a
particular Development activity that exceeds the amount budgeted or approved for such activity. Jazz shall notify Pfenex if it disputes any portion of any such invoice within ten (10) Business Days from receipt of the invoice. 

(ii) Pfenex shall perform Development activities for a single HemOnc-Pf candidate and a single
HemOnc-NextGen candidate pursuant to the applicable Development Plan at its sole cost and expense; provided, that if Jazz proposes a new HemOnc-NextGen candidate that incorporates the Half-Life Extension Component by fusion using genetic
means, other than the Amendment Date HemOnc-NextGen Product, Jazz shall reimburse Pfenex for documented internal personnel, at a rate of [***], for time actually spent by Pfenex for process development activities performed on the previous candidate
up to the date of notification of the change and prior to Pfenex beginning Pfenex Expression Feasibility Studies and process development activities on the new proposed HemOnc-NextGen candidate, and for the avoidance of doubt, such reimbursed costs
exclude costs associated with Pfenex Expression Feasibility Activities, the cost to produce material required in milestone 3 in Exhibit 6.3, and costs associated with Manufacturing Process Transfer.
Jazz may propose no more than two (2) additional HemOnc-NextGen candidates. If any of milestones 1–3 set forth on Exhibit 6.3 is achieved a second or third time by any HemOnc-NextGen Product other than a HemOnc-NextGen
Product which has previously achieved such milestone, then the milestone payment due for such HemOnc-NextGen Product candidate achieving such milestone for such second or third time is as set forth in the column entitled “Second and third
HemOnc-NextGen Products to achieve such milestone (under Section 6.2(b)(ii))” on Exhibit 6.3. The Parties acknowledge and agree that, notwithstanding the terms of the Original Agreement (including this
Section 6.2(b)(ii)), Jazz is not required to pay Pfenex for any Pfenex Expression Feasibility Activities conducted by Pfenex under the Original Agreement. 

(c) Pegaspargase Product. Prior to Option Exercise, Pfenex shall be solely responsible for all cost and expenses it incurs for
the Development of the Pegaspargase Product. After Option Exercise, the Parties will allocate the Development cost for the Pegaspargase Product as agreed by the Parties under the Option Exercise Agreement. 

6.3 Development Milestone Payments for HemOnc Products. Jazz shall notify Pfenex within ten (10) days after the achievement
by the applicable Party or its Affiliates or sublicensees of the development milestone events set forth on Exhibit 6.3. Thereafter, Pfenex shall invoice Jazz for the corresponding milestone payment set forth on
Exhibit 6.3, and Jazz 
  
 [***] Certain information

 32. 













 
shall pay each such invoice within forty-five (45) days after receipt thereof. Notwithstanding the preceding sentence, concurrently with the delivery of materials set forth in milestone
payments numbered 1 and 2 listed on Exhibit 6.3, Pfenex shall invoice Jazz for the corresponding milestone payment, and Jazz shall pay each invoice within five (5) Business Days after receipt thereof. Each
payment set forth in this Section 6.3 shall be non-refundable and non-creditable. The Parties acknowledge and agree that Jazz has previously paid to Pfenex [***]
for achievement of milestone 1 for HemoOnc-Pf, [***] for achievement of milestone 2 for HemOnc-Pf, and [***] for achievement of milestone 3 for HemOnc-Pf, in each case pursuant to this Section 6.3 under the Original Agreement. 
 (a)
Except for milestones 1-3 set forth on Exhibit 6.3 which may be payable up to three times with respect to HemOnc-NextGen Products, each milestone payment is payable one time
only with respect to the first Product to achieve such milestone, regardless of the number of times the corresponding event is achieved by a Product and regardless of the number of Products to achieve such event. Under no circumstances shall Jazz be
obligated to pay Pfenex more than eighty-four million five hundred thousand Dollars ($84,500,000) pursuant to this Section 6.3. 

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

6.5 Royalties on HemOnc Products. 
  

[***] 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. 

  
 33. 













 (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 Royalty Purchase Right. 

(a) With respect to each HemOnc Product, at any time following the first Regulatory Approval of such HemOnc Product, Jazz may elect to
replace all future royalties that would otherwise be due under Section 6.5 for such HemOnc Product with a one-time cash payment equal to the risk-adjusted net present value of such future royalties for
such HemOnc Product, determined in accordance with normal and customary valuation methodologies and taking into account relevant commercial and other factors (the “Royalty Valuation”), pursuant to this Section 6.6. 

 
 [***] 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. 

  
 34. 













 (b) If Jazz so elects, the Parties shall use good faith efforts to negotiate the
Royalty Valuation for such HemOnc Product for a period of thirty (30) days. 
 (c) If the Parties are unable to agree on the
Royalty Valuation for such HemOnc Product after such good faith negotiations within such thirty (30)-day period, such Royalty Valuation will be determined by a nationally recognized investment bank,
professional valuation firm, or consulting firm that is independent from the Parties (a “Valuation Firm”) in accordance with Section 6.6(d)–(e). 

(d) Jazz shall initially designate the Valuation Firm and notify Pfenex of such designation within fifteen (15) days of the
expiration of the thirty (30)-day period set forth in Section 6.6(b) above. If Pfenex agrees to the Valuation Firm initially designated by Jazz, then the Parties shall jointly engage such Valuation Firm
pursuant to Section 6.6(d). If, after good faith discussions, the Parties are unable to agree on a Valuation Firm, then Pfenex shall also select a Valuation Firm, and the Jazz-designated and the Pfenex-designated Valuation Firms will together
appoint a third Valuation Firm, which the Parties will engage pursuant to Section 6.6(e). 
 (e) The Parties shall engage the
Valuation Firm determined pursuant to Section 6.6(d) to promptly determine the Royalty Valuation for such HemOnc Product and to deliver to each of Jazz and Pfenex the Royalty Valuation together with a report summarizing the methodology and
basis for its determination following the procedures set forth in this Section 6.6(e). Within twenty (20) days after the selection of such Valuation Firm, each Party shall provide such Valuation Firm and the other Party a proposed Royalty
Valuation for such HemOnc Product, together with any relevant background information, assumptions and calculations in support thereof (the “Royalty Valuation Proposals”). Within fifteen (15) days after the delivery of
the last Royalty Valuation Proposal to such Valuation Firm, each Party may submit a written rebuttal of the other Party’s Royalty Valuation Proposal and may also amend and re-submit its original Royalty
Valuation Proposal. Each Party shall also provide the Valuation Firm (with a copy to the other Party) with all information reasonably requested by the Valuation Firm regarding such Royalty Valuation Proposal and any other information such Party
reasonably deems relevant to the Valuation Firm’s determination of the Royalty Valuation. Within thirty (30) days after the expiration of the fifteen (15)-day period set forth in this
Section 6.6(e) above, the Valuation Firm shall select one of the final Royalty Valuation Proposals for such HemOnc Product so submitted by one of the Parties as the Royalty Valuation for such HemOnc Product, but may not alter the terms of any
final Royalty Valuation Proposal and may not determine the Royalty Valuation for such HemOnc Product in a manner other than by selection of one of the submitted final Royalty Valuation Proposals for such HemOnc Product. 

(f) Within thirty (30) days of its receipt of the Royalty Valuation and the accompanying report, Jazz shall notify Pfenex in
writing whether Jazz elects to pay the Royalty Valuation and terminate all remaining royalties that would otherwise be due under Section 6.5 for the applicable HemOnc Product. If Jazz so elects to pay the Royalty Valuation, then (i) Jazz
shall pay Pfenex the amount of the Royalty Valuation for such HemOnc Product within fifteen (15) days after the date of Jazz’s notice of election pursuant to the preceding sentence, (ii) no further royalties will accrue or become due
under this Agreement for such HemOnc Product beyond any royalties already due or accrued at the time of Jazz’s payment to Pfenex pursuant to 
  

[***] 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. 

  
 35. 













 
clause (i), (iii) this Agreement shall be deemed amended to reflect the payment of the Royalty Valuation and the termination of the obligation to pay royalties, as set forth in this
Section 6.6(e); and (iv) each Party shall be responsible for fifty percent (50%) of the amounts invoiced by the Valuation Firm to conduct the Royalty Valuation. If Jazz does not elect to pay the Royalty Valuation or does not provide Pfenex
with notice of its election within such thirty (30)-day period, then Section 6.5 will remain unchanged for such HemOnc Product, and Jazz shall be solely responsible for the amounts invoiced by the
Valuation Firm to determine the Royalty Valuation. 
 6.7 Foreign Exchange. The rate of exchange to be used in computing
the amount of currency equivalent in Dollars of Net Sales invoiced in other currencies shall be the rate used by Jazz in its financial reporting in accordance with applicable GAAP or other standard as then-used by Jazz. 

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

6.10 Taxes. 

(a) Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising
directly or indirectly from the efforts of the Parties under this Agreement. 
 (b) Tax Cooperation. The Parties agree
to cooperate with one another and use reasonable efforts to reduce or eliminate tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Jazz to Pfenex under this Agreement. 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 

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

  
 36. 













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

(c) Withholding Tax Action. If either Party (or its Affiliates or successors) is required to make a payment to the other Party
subject to a deduction or withholding of tax, then (A) if such deduction or withholding of tax obligation arises as a result of any action by the first Party, such as a Change of Control, change of domicile, or assignment by such first Party
and such action has the effect of increasing the amount of tax deducted or withheld (a “Withholding Tax Action”), then the amount payable by the Party taking such Withholding Tax Action (in respect of which such increased deduction
or withholding is required to be made) shall be increased by the amount necessary (the “Additional Amounts”) to ensure that the other Party receives the same amount that it would have received had no such Withholding Tax Action
occurred, and (B) the Additional Amounts shall be deducted and withheld by the Party paying the Additional Amounts. The Additional Amounts, along with any other tax deducted and withheld from the payment made by such Party, shall be timely
remitted to the proper Governmental Authority for the account of the other Party in accordance with applicable Law. Notwithstanding the foregoing, any sublicense or assignment in contravention of Sections 2.1(d) or 13.6, respectively, of this
Agreement will not constitute a Withholding Tax Action. 
 (d) Refund of Additional Amounts. In the event a Party actually
receives a credit against any tax on its income for any Additional Amounts paid to a Governmental Authority on its behalf (whether for the taxable year with respect to which such Additional Amounts are deducted and withheld, or in any prior or
subsequent taxable year), the Party obtaining such credit shall refund and pay to the other Party an amount equal to the lesser of the credit obtained and such Additional Amounts. Whether a credit is obtained for Additional Amounts or for other
taxes paid by a Party shall be determined in a manner consistent with applicable Laws.

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. 

(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.

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 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.

 41. 













 (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 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 
  
 [***] 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. 

  
 42. 













 
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 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.

INDEMNIFICATION 

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 case other than by Pfenex), (b) the breach of any of Jazz’s obligations, representations or warranties under this Agreement, or (c) the
willful misconduct or negligent acts of Jazz, its Affiliates, or the officers, directors, 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 
  
 [***] 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. 

  
 46. 













 
indemnification procedures set forth in Section 9.3 and Jazz’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 9.1 for which Pfenex is obligated to indemnify the Jazz Indemnitees under Section 9.1. 
 9.3
Indemnification Procedures. The Party claiming indemnity under this Article 9 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being 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:

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;

 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 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 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 

 
 [***] 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. 

  
 50. 













 
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. 
 (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. Upon any notice of termination of HemOnc-Pf, Pfenex may notify Jazz in writing that Pfenex desires to negotiate for a license to any or all HemOnc-Pf data Controlled by Jazz that was generated by Jazz pursuant to this Agreement (the “Jazz HemOnc-Pf Data”). Upon such request, if Jazz also
desires to negotiate for such license, Jazz may provide Pfenex with access to the applicable Jazz HemOnc-Pf Data. Pfenex may, within thirty (30) days following the delivery of the Jazz HemOnc-Pf Data to Pfenex by Jazz, notify Jazz that Pfenex desires to continue to negotiate for a license to any or all of the Jazz HemOnc-Pf Data. If Pfenex elects to
negotiate for a license to any or all of the Jazz HemOnc-Pf Data, the Parties shall negotiate the terms of such license for a ninety (90)-day period from the date of
Pfenex’s election; provided, that if the Parties are unable to agree on the terms of such license, Jazz will have no obligation to grant Pfenex any right, title, interest, or license in or to the Jazz
HemOnc-Pf Data and Pfenex will not obtain any right, title, interest, or license in or to the Jazz HemOnc-Pf Data. Regardless of whether the Parties agree on the terms
of a license for the Jazz HemOnc-Pf Data, Jazz retains exclusive ownership of the Jazz HemOnc-Pf Data. 

(b) HemOnc-NextGen. Upon any notice of termination of HemOnc-NextGen, Pfenex may notify Jazz in writing that Pfenex desires to
negotiate for a license to any or all HemOnc-NextGen data Controlled by Jazz that was generated by Jazz pursuant to this Agreement (the “Jazz HemOnc-NextGen Data”). Upon such request, if Jazz also desires to negotiate for such
license, Jazz may provide Pfenex with access to the applicable Jazz HemOnc-NextGen Data. Pfenex may, within thirty (30) days following the delivery of the Jazz HemOnc-NextGen Data to Pfenex by Jazz, notify Jazz that Pfenex desires to continue
to negotiate for a license to any or all of the Jazz HemOnc-NextGen Data. If Pfenex elects to negotiate for a license to any or all of the Jazz HemOnc-NextGen Data, the Parties shall negotiate the terms of such license for a ninety (90)-day period from the date of Pfenex’s election; provided, that if the Parties are unable to agree on the terms of such license, Jazz will have no obligation to grant Pfenex any right, title,
interest, or license in or to the Jazz HemOnc-NextGen Data and Pfenex

 51. 













 
will not obtain any right, title, interest, or license in or to the Jazz HemOnc-NextGen Data. Regardless of whether the Parties agree on the terms of a license for the Jazz HemOnc-NextGen Data,
Jazz retains exclusive ownership of the Jazz HemOnc-NextGen Data. 
 (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. 
 (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, then Section 11.4(a) applies; 
 (ii) if Pfenex terminates with respect to
HemOnc-NextGen, then Section 11.4(b) applies; 
 (iii) if Pfenex terminates with respect to the Pegaspargase Product, then
Section 11.4(c) applies; 
 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,
Section 11.4, Section 11.5, 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) and 2.5(c)(i) 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

the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 

  
 53. 













 
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 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

requested with respect to the omitted portions. 

  
 54. 













 
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, 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 Amendment Effective Date, all prior and contemporaneous agreements and understandings between the Parties with respect to the subject matter hereof, including the
Confidentiality Agreements and the Original Agreement. 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 Amendment Effective Date, by the other Party of its
obligations under the Confidentiality Agreements or the Original Agreement. For clarity, the Parties agree and acknowledge that the Original Agreement shall govern the Parties’ rights and obligations regarding the subject thereof from the
Effective Date to the Amendment Effective

Date (except that the Parties acknowledge and agree that, notwithstanding the terms of the Original Agreement (including, in particular, Section 6.2(b)(ii)), Jazz is not required to pay
Pfenex for any Pfenex Expression Feasibility Activities conducted by Pfenex under the Original Agreement). 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) 365(n) Rights. 

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

 56. 













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

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

(i) Establishment and Update. Within [***] days after Jazz’s written request, the Parties shall enter into an escrow
agreement (the “Escrow Agreement”) with a mutually agreeable Third Party escrow agent (the “Escrow Agent”). The Escrow Agreement will contain terms and conditions that are typically included in such a technology
escrow agreement, [***]. Under the Escrow Agreement, Pfenex shall, within [***] Business Days of execution of the Escrow Agreement, deposit with the Escrow Agent [***] (the “Escrow Materials”). Pfenex shall keep the Escrow Materials
reasonably current and complete, and shall be updated by or on behalf of Pfenex from time to time and in no event more than [***] days after Pfenex has made one or more material modifications to any of the Escrow Materials. Jazz shall reimburse
Pfenex for the reasonable out-of-pocket costs incurred by Pfenex in connection with the Escrow Agreement and preparation and deposit of Escrow Materials with the Escrow
Agent. 
 (ii) Right to Use Escrow Materials. Following an Escrow Triggering Event, Jazz may access and use [***] the Escrow
Materials [***], and, effective as of an Escrow Triggering Event, [***]. 
 (d) Development
Step-In. In addition to its other rights under this Agreement, and notwithstanding anything herein to the contrary, upon the occurrence of the Development Step-In
Triggering Event, Jazz may notify Pfenex in writing that a Development Step-In Trigger Event has occurred. Pfenex shall have [***] Business Days to dispute the occurrence of the Development Step-In Triggering Event. If Pfenex disputes such occurrence, the Parties shall discuss in good faith. If Pfenex agrees that a Development Step-In Triggering Event has
occurred, or does not respond within such [***]-Business Day period, [***]. 
 (e) Technology Transfer and Assistance. In
connection with Jazz’s rights to access and use the Escrow Materials pursuant to Section 13.2(c)(ii), Pfenex shall provide to Jazz [***]. 

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

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 
  

[***] 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. 

  
 59. 













 
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. 

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.
