 ARTICLE VI. 

PRODUCT TRADEMARK; INTELLECTUAL PROPERTY LITIGATION 

Section 6.1    Product Trademarks. 

(a) Hospira shall have the sole right to select Product names, trademarks, trade dress, style of packaging, labeling and the
like used in connection with the commercialization of Product including special promotional or advertising taglines. Each Product-specific trademark, and all goodwill associated therewith, and all applications, registrations, extensions and renewals
and other rights relating thereto, shall be collectively referred to as a “Product Trademark”. Hospira shall be the exclusive owner of each Product Trademark. Hospira shall have the sole right to register and renew, at its expense,
each such Product Trademark in any country or jurisdiction of Hospira’s choosing. 
 (b) To the extent permitted by
Applicable Law, Hospira shall (i) include the phrase “Licensed from Pfenex Inc.” and the Pfenex logo in the Product Documentation (excluding Product labels and packaging) used in each Major Market and Australia and Japan, to be
placed in a size [***] of the size of the Hospira logo) and location reasonably determined by Hospira, and (ii) include the phrase “Licensed from Pfenex Inc.” on the Product
labels and packaging used in each Major Market and Australia and Japan, to be placed in a size and location reasonably determined by Hospira, in each case (i) and (ii), subject to Hospira obtaining necessary authorization(s) therefor from
applicable Regulatory Agency(ies). Accordingly, Hospira shall use Commercially Reasonable Efforts to obtain such necessary authorizations. Hospira shall have no obligation to remove or modify the phrase “Licensed from Pfenex Inc.”
and/or the Pfenex logo from the Product Documentation (including Product labels and packaging) once finalized. Subject to the foregoing, Pfenex hereby grants to Hospira, its Affiliates and Third Party distributors the right to use the Pfenex name
and logo in connection with Hospira’s obligations pursuant to this Section 6.1(b). The Pfenex logo and the goodwill associated therewith, and all applications, registrations, extensions and renewals and other rights relating
thereto, shall be the sole property Pfenex. 
 Section 6.2    Ownership of Inventions. As
between the Parties, all right, title and interest to inventions and other intellectual property (including Know-How) made (a) by Hospira personnel in connection with this Agreement, but not any Pfenex personnel, shall be owned by Hospira
(“Hospira Inventions”), (b) by Pfenex personnel in connection with this Agreement, but not any Hospira personnel, shall be owned by Pfenex (“Pfenex Inventions”) and (c) made jointly by personnel of Hospira
and Pfenex in connection with this Agreement shall be jointly owned by Hospira and Pfenex (“Joint Inventions”); provided, that Hospira hereby grants to Pfenex a fully-paid, irrevocable, non-exclusive license (with the right
to grant and authorize sublicenses) [***]. Notwithstanding the foregoing, Pfenex shall only have the right to sublicense its rights under the Hospira Manufacturing License to Third Parties
(i) solely for use with manufacturing/production of products implementing or utilizing any Pfenex Technology or

Pfenex Expression Technology, and (ii) solely from Third Parties whom Pfenex has obtained Control of manufacturing developments which are substantially similar those licensed to Pfenex under
the Hospira Manufacturing License (i.e., which are licensed to Hospira hereunder). Except as expressly provided in this Agreement, it is understood that neither Party shall have any obligation to account to the other for profits, or to obtain any
approval of the other Party to license, assign or otherwise exploit any Joint Inventions or Patents claiming the same (any, a “Joint Patent”), by reason of joint ownership thereof, and each Party hereby waives any right it may have
under the Applicable Laws of any jurisdiction to require any such approval or accounting. Each Party shall make such assignments, and hereby makes such assignments, as necessary to effect the foregoing. 

Section 6.3 Patent Prosecution and Maintenance of Inventions. 

(a)    Hospira Patents. Hospira shall have the sole right, in its sole discretion, to
pursue the Prosecution and Maintenance of Patents claiming Hospira Inventions. 

(b)    Pfenex Patents. Pfenex shall have the sole right, in its sole discretion, to pursue
the Prosecution and Maintenance of Patents claiming Pfenex Inventions. 
 (c)    Joint
Patents. Decisions regarding the Prosecution and Maintenance of Joint Patents shall be made jointly by Pfenex and Hospira through the oversight of the Executive Steering Committee. Upon the identification of a Joint Invention, the Executive
Steering Committee shall (i) promptly discuss such Joint Invention and, in the event Hospira and Pfenex reasonably believe that such Joint Invention is patentable, select a mutually acceptable law firm to conduct a patentability assessment for
the purpose of determining whether the Joint Invention is patentable, (ii) promptly review the patentability assessment and discuss the desirability of filing a Joint Patent, (iii) make the final decision with respect to any such filings,
including the jurisdictions in which such filings are to be made, as soon as practicable, and (iv) designate the Party (for purposes of this Section 6.3(c), the “Controlling Party”) to be responsible for the
Prosecution and Maintenance of such Joint Patents. The Controlling Party shall be responsible, using counsel selected by the Executive Steering Committee, to implement the decisions of the Executive Steering Committee regarding the Prosecution and
Maintenance of Joint Patents. The Controlling Party shall provide the other Party an opportunity to review and comment upon the text of the applications within the Joint Patents at least ten (10) Business Days before filing with any patent
office. The Controlling Party shall provide the other Party with a copy of each patent application within the Joint Patents as filed, together with notice of its filing date and serial number. The Controlling Party shall keep the other Party advised
of the status of all communications, actual and prospective filings or submissions regarding Joint Patents, and shall provide the other Party an opportunity to review and comment on any such communications, filing and submissions proposed to be sent
to any patent office. The Controlling Party shall also notify the Executive Steering Committee of the grant of any Joint Patents. The Controlling Party shall not cease the Prosecution and Maintenance, or modify the claims, of any Joint Patents in
any country, unless approved by the other Party (which approval shall not be unreasonably withheld). All Third Party costs incurred by the Controlling Party for the Prosecution and Maintenance of Joint Patents hereunder shall be shared equally by
the Parties. Accordingly, the other Party shall pay to the Controlling Party its share [***] of any such

Third Party costs not disputed in good faith within thirty (30) days of receipt of an invoice therefor and any disputed amount shall by paid within fifteen (15) days after the
resolution of such dispute pursuant to Sections 10.6 and 13.4. The Controlling Party shall provide the other Party with any reasonable documentation in connection with any such invoice. 

(d)    Disclosures. Each Party acknowledges the highly proprietary and confidential nature of
unpublished patent applications and related information and without limiting the provisions of Article VIII agrees to limit the access to any such applications and information received from the other Party hereunder to those who need such
access for the purposes of this Section 6.3 and limit the use thereof solely to the purposes of this Section 6.3. Without limiting the foregoing, any disclosures made pursuant to this Section 6.3 will be
structured in a manner so as provide reasonable access to the applicable information while limiting the risk of adversely affecting the patentability of the subject matter disclosed. 

Section 6.4 Intellectual Property Strategy. 

(a)    Hospira shall, at Hospira’s sole cost and expense, have sole control over the creation and
implementation of any strategy related to any Actions (including inter partes reviews and declaratory judgments) with respect to Patents of Third Parties, in each case with respect to the development, manufacture, launch (including obtaining
Regulatory Approval), marketing, commercialization and sale of Product in all markets, including the sole right to determine (i) when and if to initiate any such Action with respect to any Third Party’s Patent (other than as covered by the
terms of Section 6.6), including by way of example any nullity or invalidity case brought against any Third Party’s Patents specific to the development, manufacture, launch, marketing, commercialization and sale of Product;
(ii) the earliest date on which Product will be manufactured, imported, used, offered for sale and/or sold in any given country; (iii) when and how to change the development or manufacture of Product (provided that any modification to the
Manufacturing Strain shall be subject to Section 3.1(e)) in order to minimize the effect of any Third Party’s Intellectual Property from the development, manufacture, launch, marketing, commercialization and sale of Product, such as
the institution of circumvention strategies or the proactive seeking of a license from a Third Party; (iv) the appropriate course of action in the event any Third Party commences an Action alleging that Product or the development, manufacture,
launch, marketing, commercialization or sale of Product infringes any Intellectual Property of such Third Party (other than as covered by the terms of Section 6.5), including assuming and controlling the defense of any such Action; and
(v) when and if to settle, compromise or consent to any judgment with respect to any Action with respect to any Third Party’s Intellectual Property; provided, that Hospira shall be required to obtain Pfenex’s prior written
consent (such consent not to be unreasonably withheld, conditioned or delayed) to the extent the same would likely have a material adverse effect on Pfenex, its Affiliate or their rights (the “IP Strategy”). For clarity, nothing in
this Section 6.4 shall limit Pfenex’s right with respect to Actions related to Patents or other Intellectual Property of Third Parties in connection with the development, manufacture, launch (including obtaining Regulatory
Approval), marketing, commercialization and sale of products other than Product hereunder. 
  

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

 (b)    Pfenex shall provide all cooperation and assistance
reasonably requested by Hospira in connection with Hospira’s implementation of the IP Strategy, including (i) providing Hospira prompt written notice of any Action commenced by any Third Party against Pfenex alleging that Product or the
Business infringes any Intellectual Property of such Third Party, (ii) providing Hospira with documents (whether in written, electronic or other form) related to Product and/or the Business, including documents related to the development of
Product or the processes used to manufacture Product, (iii) identifying and describing any Intellectual Property that has been incorporated into Product by Pfenex, (iv) allowing inspection, whether court-ordered or otherwise, of any
facility owned, operated or controlled by Pfenex or its Affiliates and (v) identifying and providing witnesses who will assist in the preparation of evidence, provide written evidence, appear as witnesses in court and assist in other ways that
Hospira reasonably requests. To the extent that the cooperation or assistance requested results in external costs being incurred by Pfenex, then Hospira shall be responsible for the payment of all reasonably incurred external expenses in accordance
with a budget to be mutually agreed upon by the Parties. 
 (c)    Pfenex shall not commence any Action
with respect to any Patents of a Third Party in connection with the development, manufacture, launch (including obtaining Regulatory Approval), marketing, commercialization and sale of Product or take any other action that violates or conflicts with
Hospira’s rights under Section 6.4(a) without Hospira’s prior written consent. Notwithstanding anything to the contrary in this Agreement, if Pfenex commences any such Action in contravention of the proceeding sentence (an
“Off-Strategy Action”), such commencement shall constitute a material breach by Pfenex of this Agreement, and, without limiting Hospira’s rights with respect to such material breach and notwithstanding anything contained herein
to the contrary, Pfenex shall act in accordance with any instructions from Hospira with respect to such Off-Strategy Action, including instructions to (i) terminate such Off-Strategy Action or (ii) relinquish control of such Off-Strategy
Action to Hospira, whereupon Pfenex will be responsible for all IP Costs incurred by either Party in connection with such Off-Strategy Action. 

Section 6.5 Manufacturing Process. 

(a)    In the event that any Third Party commences any Action against either Party or any of such
Party’s Affiliates alleging that the manufacture of Product (including the use of any Pfenex Technology in the manufacture of Product) infringes any Intellectual Property of such Third Party (a “Manufacturing Action”), the
Party against whom such Action is commenced shall provide the other Party prompt written notice thereof. Following receipt of such notice, Hospira shall have the sole right to determine the appropriate course of action, including by way of example,
assuming and controlling the defense of such Manufacturing Action and/or seeking a license from such Third Party with respect to such Third Party’s Intellectual Property. If Hospira elects to assume control over the defense of any such
Manufacturing Action where Pfenex or its Affiliate is a defendant, then Pfenex or its Affiliate shall have the right to participate with counsel of its selection (at Pfenex’s sole cost and expense) and Hospira shall subject to
Section 6.5(c) continue to control and defend Pfenex or its Affiliate until final judgment in such Manufacturing Action.

 (b)    Pfenex shall provide all cooperation and assistance
reasonably requested by Hospira in connection with any Manufacturing Action, including (i) providing Hospira with detailed responses to its inquiries, (ii) providing Hospira with documents (whether in written, electronic or other form)
related to the manufacturing process or the practice of the Pfenex Technology, (iii) identifying and describing any Intellectual Property that has been incorporated into the processes to manufacture Product by Pfenex, and (iv) identifying
and providing witnesses who will assist in the preparation of evidence, provide written evidence, appear as witnesses in court and assist in other ways that Hospira reasonably requests. 

(c)    Hospira may settle, compromise or consent to any judgment with respect to any Manufacturing Action
without the prior written consent of Pfenex on fifteen (15) Business Days’ notice to Pfenex (together with a complete copy of such proposed settlement, compromise, consent or judgment and such other documents as Pfenex may reasonably
request); provided, that if prior to the expiration of such fifteen (15) Business Day period, Pfenex determines in good faith, and advises Hospira of such determination in writing, that such settlement, compromise or consent to judgment
would likely have a material adverse impact on Pfenex, or its Affiliate or their rights, then Hospira shall not settle, compromise or consent to any judgment with respect to such Manufacturing Action without the prior written consent of Pfenex (not
to be unreasonably withheld, delayed or conditioned). 
 (d)    Pfenex will be responsible for all
costs relating to any settlements, compromises or judgments arising from (and shall promptly reimburse Hospira for its out-of-pocket costs and expenses in connection with) any Manufacturing Action to the extent alleging that the Manufacturing Strain
(or any constituent component thereof) infringes any Intellectual Property of any Third Party. 
 Section 6.6
Enforcement Actions. 
 (a)    Each Party shall promptly give the other Party written notice
(each, an “IP Assertion Notice”) of any actual or suspected infringements, misappropriations or other violations by a Third Party of the Pfenex Technology (excluding Joint Patents) (“Infringing Activity”) that come
to such Party’s or any of its Affiliates’ attention, as well as the identity of such Third Party and any evidence of such Infringing Activity within such Party’s or any of its Affiliates’ custody or control that such Party or any
of its Affiliates is reasonably able to provide. 
 (b)    Pfenex shall have the first right, but not
the obligation, at Pfenex’s sole cost and expense, to take any action in response to such Infringing Activity and/or to enter into or permit the settlement of any litigation or other enforcement action (collectively, “Enforcement
Actions”); provided, that Pfenex shall provide prompt written notice of any Enforcement Action to Hospira arising from the development, manufacture, launch, marketing, commercialization and sale of a Competing Product (each, a
“Competing Product Enforcement Action”), permit Hospira (subject to the Common Interest Agreement) to review and comment on such Competing Product Enforcement Action and give reasonable consideration to any comments made by Hospira
in relation to such Competing Product Enforcement Action. If required by Applicable Law and to the extent Pfenex does not have standing, Hospira shall permit, and shall take all actions reasonably necessary to enable, an

Enforcement Action to be brought in its name, including being joined as a necessary party, at Pfenex’s sole cost and expense. Pfenex may settle, compromise or consent to any judgment with
respect to any Enforcement Action without the prior written consent of Hospira on fifteen (15) Business Days’ notice to Hospira; provided, that if, prior to the expiration of such fifteen (15) Business Day period, Hospira
determines, and advises Pfenex of such determination in writing, that a settlement, compromise or consent to judgment with respect to a Competing Product Enforcement Action would likely have a material adverse impact on Hospira, or its Affiliate or
their rights or reduce Pfenex’s obligations under this Agreement, then Pfenex shall not settle, compromise or consent to any judgment with respect to such Competing Product Enforcement Action without the prior written consent of Hospira (which
consent shall not be unreasonably withheld, delayed or conditioned). 
 (c)    If Pfenex does not
institute a Competing Product Enforcement Action against the Infringing Activity involving the Pfenex Technology within one (1) month from the date of the IP Assertion Notice or such shorter period as is reasonably necessary for Hospira to take
action necessary to bring such Competing Product Enforcement Action and Pfenex has not provided notice to Hospira specifying that (i) the initiation of such Competing Product Enforcement Action is likely to invalidate or narrow the claims of
any Pfenex Patents and (ii) such invalidation or narrowing would likely have a material adverse impact on Pfenex or its Affiliates, or the Pfenex Technology, Hospira shall have the right, but not the obligation, at Hospira’s sole cost and
expense, to bring the Competing Product Enforcement Action; provided, that Hospira shall provide prompt written notice of any such Competing Product Enforcement Action to Pfenex, permit Pfenex (subject to the Common Interest Agreement defined
below) to review and comment on such Competing Product Enforcement Action and give reasonable consideration to any comments made by Pfenex in relation to such Competing Product Enforcement Action. In such case and if required by Applicable Law and
to the extent Hospira does not have standing, Pfenex shall permit, and shall take all actions reasonably necessary to enable, an Competing Product Enforcement Action to be brought in its name, including being joined as a necessary party, at
Hospira’s sole cost and expense. Hospira may not enter into any settlement or consent to any judgment with respect to any such Competing Product Enforcement Action without the prior written consent of Pfenex (not to be unreasonably withheld,
delayed or conditioned). 
 (d)    In any Enforcement Action instituted by either Pfenex or Hospira to
enforce the Pfenex Technology as provided herein above, the other Party (the “Cooperating Party”) shall, at the reasonable request of the Party initiating such Enforcement Action, cooperate and provide reasonable assistance to the
Party prosecuting the Enforcement Action, including (i) providing the prosecuting Party with documents (whether in written, electronic or other form) related to the Pfenex Technology, (ii) identifying and describing any Intellectual
Property that has been incorporated into the Pfenex Technology by the Cooperating Party, (iii) allowing inspection, whether court-ordered or otherwise, of any facility owned, operated or controlled by the Cooperating Party and
(iv) identifying and providing witnesses who will assist in the preparation of evidence, provide written evidence, appear as witnesses in court and assist in other ways that the prosecuting Party reasonably requests. To the extent that the
cooperation or assistance requested results in external costs being incurred by the Cooperating Party, then the

requesting Party shall be responsible for the payment of all reasonably incurred external expenses. 

(e)    Each Party shall promptly give the other Party written notice of any actual or suspected
infringements, misappropriations or other violations by a Third Party of any Joint Patent (“Competing Infringing Activities”) that comes to such Party’s or any of its Affiliates’ attention. The Executive Steering Committee
shall (i) promptly discuss such Competing Infringing Activities and the strategy for enforcing the Joint Patents, and (ii) designate (with the agreement of the Party) the Party to be responsible for controlling such Enforcement Action with
respect to the Joint Patents; provided, that unless otherwise agreed with respect to such Competing Infringing Activities, Hospira shall be the controlling Party unless it notifies Pfenex within thirty (30) days of notice of the
applicable Competing Infringing Activities or such shorter period as is reasonably necessary for Hospira to take actions necessary to bring such Enforcement Action (the Party controlling such Enforcement Action, the “Enforcing
Party”). The other Party shall have the right to fund up to [***] of the out-of-pocket costs of such Enforcement Action as incurred; accordingly, the other Party shall notify the
Enforcing Party as what, if any, portion of such costs it intends to fund and it shall be responsible for such portion unless the other Party provides sixty (60) days’ prior written notice to the Enforcing Party indicating that it does not
intend to bear any further of such costs. 
 Section 6.7 Reimbursement Requirements. To the extent that any
Party would be required pursuant to this Article VI to reimburse or pay the other Party for any costs or expenses incurred by such other Party, such obligation shall be subject to submission by such other Party of reasonable documentation
with respect thereto. To the extent that either Party would be entitled to be reimbursed for, or otherwise have paid, any costs or expenses incurred by such Party, such costs and expenses shall only be reimbursed or paid to the extent reasonably
incurred by such Party. Third Party costs not disputed in good faith within thirty (30) days of receipt of an invoice therefor and any disputed amount shall by paid within fifteen (15) days after the resolution of such dispute pursuant to
Sections 10.6 and 13.4.  
 Section 6.8 Recovered Amounts. Any monetary damages, court-ordered
third party costs, settlements, royalties or other recovery received from any Third Party resulting from, arising out of or relating to any Competing Product Enforcement Action or Enforcement Action for Competing Infringing Activities shall be
distributed to the Parties on a pro rata basis based upon the IP Costs paid by each Party in connection with such Enforcement Action. 

Section 6.9 Common Interest Agreement. The Parties have entered in that certain Common Interest Agreement, dated
as of October 22, 2014 (the “Common Interest Agreement”) the terms and conditions of which shall continue to govern the conduct of Due Diligence and sharing of Intellectual Property-Related Materials (each as defined therein).
The Parties acknowledge that the terms and conditions of the Common Interest Agreement are in addition to the terms and conditions hereof (including Sections 8.1, 8.2 and 8.3) and are not superceded hereby. 

Section 6.10 Confidentiality of Actions. To the extent reasonably possible and permitted by Applicable Law and
determined desirable by Hospira, each of the Parties shall take 
  

[***] 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. 

  
 40 








 
all steps necessary to maintain as confidential, and to not publish or otherwise disclose, the existence and the substance of the IP Strategy and any Action commenced in connection therewith,
including any Manufacturing Action or any Competing Product Enforcement Action, and the existence and terms of any settlement or any judgment, award, decree or determination, or consent to any of the foregoing. 

Section 6.11 Patent Marking. Hospira shall mark (or cause to be marked) Product marketed and sold hereunder with
appropriate Pfenex Patent numbers or indicia at Pfenex’s request to the extent permitted by Applicable Law, in those countries in which such notices impact recoveries of damages or remedies available with respect to infringements of Patents;
provided, however, that Pfenex shall notify Hospira two (2) years in advance of the expiration of any such Pfenex Patent and shall immediately notify Hospira upon the invalidation of any such Pfenex Patent. 

Section 6.12 Article XI Not Applicable. Article XI shall not apply to the extent its application would be
inconsistent with this Article VI.

shall notify the non-appointing Party and the non-appointing Party shall have the right to comment on each such appointee, which such comments the appointing Party shall consider in good faith. Unless otherwise agreed by the Parties, the Executive
Steering Committee and each Working Committee shall have at least one (1) representative with relevant decision-making authority from each Party such that such committee is able to effectuate all of its decisions within the scope of its
responsibilities. Each member of the Executive Steering Committee shall be subject to the obligations of non-use and non-disclosure of Confidential Information set forth in Article VIII. Notwithstanding anything herein to the contrary, if
requested by Hospira, Pfenex shall not have the right to appoint as a member to the Executive Steering Committee member hereunder any individual that is serving as a management committee member under Pfenex’s collaboration with Strides Arcolab
Limited and its affiliates (i.e., an appointee to the joint steering committee thereunder). 
 Section 7.3 Meeting
Requirements. The Executive Steering Committee shall meet on a quarterly basis (or less frequently if Pfenex and Hospira mutually agree) during the Term. The Executive Steering Committee may meet by phone, videoconference or in person. Each
meeting shall be held on a date to be agreed upon by Pfenex and Hospira. Notwithstanding the foregoing, meetings may be called at any time if requested by one of Pfenex and Hospira by prior written notice, including the corresponding agenda of the
meeting, sent to Pfenex and Hospira, as applicable, at least one (1) month in advance; provided, that if a meeting is required to be convened promptly pursuant to this Agreement, Pfenex and Hospira shall exercise Commercially Reasonable
Efforts to convene such meeting as promptly as is practicable. Pfenex and Hospira agree that reasonable flexibility is necessary, and therefore, three (3) different dates shall be proposed for each meeting, whenever possible. Meetings shall
only be effective if at least one (1) representative designated by Hospira and one (1) representative designated by Pfenex are present or participating in the meeting. 

Section 7.4 Decision-Making; Dispute Resolution. 

(a)    The Executive Steering Committee shall have a single chairperson who will (i) solicit agenda
items from the other Executive Steering Committee members, coordinate and prepare the agenda (which shall include any agenda items reasonably proposed by Executive Steering Committee members from the other Party), provide the agenda along with
appropriate information for such agenda reasonably in advance (to the extent possible) of any meeting and ensure the orderly conduct of the Executive Steering Committee’s meetings, (ii) attend (subject to the below) each meeting of the
Executive Steering Committee, and (iii) prepare and issue minutes of each meeting (which shall accurately reflect the discussions and decisions of the Executive Steering Committee at such meeting) in accordance with Section 7.5.
Such minutes from each Executive Steering Committee meeting shall not be finalized until the Executive Steering Committee members from the other Party have reviewed and confirmed the accuracy of

such minutes as described in Section 7.5 and if not previously confirmed, such matter shall be the first order of business at the next Executive Steering Committee meeting. The Party
appointing the chairperson shall alternate between Pfenex and Hospira every calendar year, and shall initially be designated by Hospira. In the event the chairperson or another representative of the Executive Steering Committee from either Party is
unable to attend or participate in any meeting of the Executive Steering Committee, the Party who appointed such Executive Steering Committee chairperson or representative may appoint a substitute chairperson or other representative for that
meeting. All decisions of the Executive Steering Committee and any Working Committee shall be made by consensus, with each Party having one (1) vote. Each Party shall work in good faith to reach consensus on matters and act in the general
spirit of cooperation and in no event shall either Party unreasonably withhold, condition or delay any approval or other decision of the Executive Steering Committee or a Working Committee hereunder. In the event a Working Committee fails to reach
consensus with respect to a particular matter within its authority, then upon request by either Party such matter shall be referred to the Executive Steering Committee for resolution. 

(b)    If the Executive Steering Committee is unable to reach a decision as to any matter within its
authority (including any matter expressly required to be resolved by the Executive Steering Committee pursuant to this Agreement) after a period of ten (10) Business Days, then either Pfenex or Hospira may provide written notice of such dispute
to the Chief Executive Officer of the other Party and such matter shall be resolved as set forth below. The Chief Executive Officers (or their respective designees, who shall be senior officers of Pfenex and Hospira, but shall not be members of the
Executive Steering Committee) of each of Pfenex and Hospira shall discuss the dispute in person or telephonically and use their good faith efforts to resolve the dispute within thirty (30) days after submission of such dispute to such officers.
If any such dispute is not resolved by the Chief Executive Officers or their designees within thirty (30) days after submission of such dispute to such officers, then: 

(i)    except the Chief Executive Officer of Pfenex shall have authority to finally resolve, in such
officer’s reasonable discretion exercised in good faith, all matters related to the Pfenex Technology including the Prosecution and Maintenance of the Pfenex Inventions and the enforcement thereof (except for matters that Hospira has the right
to control pursuant to Section 6.6(c)); 
 (ii)    the General Counsel of Hospira shall have
authority to finally resolve, in such officer’s reasonable discretion exercised in good faith, all matters related to the IP Strategy and the matters related to the Hospira Technology including the Prosecution and Maintenance of the Hospira
Inventions and the enforcement thereof; 
 (iii)    the Chief Commercial Officer of Hospira shall have
the authority to finally resolve, in such officer’s reasonable discretion exercised in good faith, all matters related to the commercialization of Product under this Agreement; 

(iv)    the Chief Scientific Officer of Hospira shall have authority to finally resolve, in such
officer’s reasonable discretion exercised in good faith, (A) all matters related to clinical protocol for the conduct of the Comparative Clinical Study, (B) all matters

related to regulatory affairs (including with respect to communication to the FDA and the EMA) regarding Product and (C) subject to Section 3.2(b), all matters related to the
Development Plan, the Development Program and Product Data Sheet; 
 (v) the Senior Vice President of Operations of Hospira
shall have authority to finally resolve, in such officer’s reasonable discretion exercised in good faith, all matters related to commercial scale manufacturing of Product; and 

(vi) the Chief Executive Officer of Hospira shall have authority to finally resolve, in such officer’s reasonable
discretion exercised in good faith, any other matter not previously addressed in clauses (i) through (v) above. 
 Notwithstanding
the foregoing, neither Party shall have any final decision-making authority with respect to matters described in Section 3.1(e), Section 7.1(i) or Section 7.1(j). 

Section 7.5 Meeting Minutes. The Parties shall reasonably cooperate to finalize the definitive minutes of the
Executive Steering Committee no later than thirty (30) days after the meeting to which the minutes pertain, as follows: (i) the chairperson of Executive Steering Committee shall be responsible for preparing and sending a draft of the
minutes to the other Party’s representatives, and shall furnish such draft within ten (10) days of such meeting, (ii) the other Party’s representatives shall have ten (10) days after receiving the draft minutes to collect
comments and to discuss any modifications thereon and (iii) within the following ten (10) days any disputes as to the minutes shall be resolved between the Parties and the final version of the minutes shall be issued by the Party
appointing the chairperson which shall be subject to approval by Hospira and Pfenex by signing and dating the minutes or unanimous approval of the Executive Steering Committee at its meeting. The minutes shall include a list of any actions,
decisions or determinations approved by the Executive Steering Committee and a list of any issues yet to be resolved. In addition, the minutes shall set forth the place and date where the next meeting shall be held. 

Section 7.6 Expenses. Each of Pfenex and Hospira shall be responsible for the expenses of the participation of its
representatives in the Executive Steering Committee and any Working Committees, including travel costs. 
 Section 7.7
Working Committees. Each Working Committee shall (a) be comprised as the Executive Steering Committee determines is necessary to fulfill its responsibilities (it being understood that a particular Working Committee may not necessarily
have the same number of representatives from each Party) and (b) report into and be subordinate to the Executive Steering Committee. A Working Committee shall only have the authority expressly delegated to such Working Committee by the
Executive Steering Committee. Each Working Committee shall keep the Executive Steering Committee regularly informed of the activities that it is tasked with overseeing or otherwise carrying out, both through in-person and written reporting as
reasonably necessary for the Executive Steering Committee to fulfill its responsibilities with respect thereto.

 44 








 (a)    General. Notwithstanding the creation
of the Executive Steering Committee and any Working Committee, each Party shall retain the rights, powers and discretion granted to it hereunder, and no Committee shall be delegated or vested with rights, powers or discretion unless such delegation
or vesting is expressly provided herein, or the Parties expressly so agree. Neither the Executive Steering Committee nor any Working Committee shall have the power to (a) amend, modify or waive compliance with this Agreement, (b) to
determine whether or not a Party has met its diligence or other obligations under the Agreement, or (c) to determine whether or not a breach of this Agreement has occurred, and no decision of the Executive Steering Committee or any such Working
Committee, as applicable, shall be in contravention of any terms and conditions of this Agreement. It is understood and agreed that issues to be formally decided by the Executive Steering Committee and any Working Committee, as applicable, are only
those specific issues that are expressly provided in this Agreement to be decided by the Executive Steering Committee and any such Working Committee, as applicable. 

(b)    Withdrawal. At any time after the first anniversary of the Effective Date and for
any reason, Pfenex shall have the right to withdraw from participation in the Executive Steering Committee or any or all of the Working Committees upon notice to Hospira referencing this Section 7.8(b), which notice shall be effective
immediately upon receipt. Thereafter, Hospira shall have the sole authority to resolve any matter presented to the Executive Steering Committee or any Working Committee from which Pfenex has withdrawn. For purposes of clarification, Pfenex’s
withdrawal from the Executive Steering Committee or any Working Committee shall not affect any other obligation or responsibility of Pfenex set forth in this Agreement. 

Section 7.9 Day-to-Day Responsibilities. Each Party shall be responsible for day-to-day implementation and
operation of the activities hereunder for which it has or is otherwise assigned responsibility under this Agreement; provided, that such implementation is not inconsistent with the express terms of this Agreement, the decisions of the
Executive Steering Committee or any Working Committee within the scope of its authority specified herein or Applicable Law. 

Section 7.10 Cooperation. A Party that is obligated to cooperate with the other Party hereunder (a) may
consider all relevant factors including its other then-current obligations and resource commitments when determining whether the cooperation activities are reasonable, and (b) shall not be obligated to obtain any additional resources (including
hire any personnel) to accomplish its cooperation hereunder. Such Party’s obligation to cooperate in a particular activity shall not alleviate the other Party’s obligation to perform the underlying activity. 

ARTICLE VIII. 

CONFIDENTIALITY; TAXES; NONSOLICITATION 

Section 8.1 Confidentiality. Each of Pfenex and Hospira acknowledges that, in the course of discussions and
negotiations and performing its obligations hereunder, (a) it has received or may receive information from the other Party and (b) the other Party may disclose to it information, data and processes that such other Party wishes to protect
from use by and disclosure to Third Parties (all information described in clauses (a) and (b), unless subject to the

Confidentiality Exceptions, “Confidential Information”). Each Party shall retain in confidence all Confidential Information of the other Party and (except as expressly provided
herein) shall not use Confidential Information of such other Party for any purpose other than the purposes indicated herein and in connection with the performance of this Agreement or disclose such Confidential Information to a Third Party other
than its Agents without the written consent of such other Party. Confidential Information shall not include information that: (i) is or becomes public knowledge (through no fault of the receiving Party or its Agents); (ii) is made lawfully
available to the receiving Party, other than under an obligation of confidentiality, by an Third Party that, to the knowledge of the receiving Party, is under no duty of confidentiality to the disclosing Party; (iii) is already in the receiving
Party’s possession at the time of receipt from the disclosing Party (and such prior possession can be reasonably demonstrated by competent evidence by the receiving Party) other than as a result of disclosure by an Third Party that, to the
actual knowledge of the receiving Party, was under a duty of confidentiality to the disclosing Party with respect to such information; or (iv) is independently developed by the receiving Party and/or Affiliates without the use of or reference
to Confidential Information of the other Party (and such independent development can be reasonably demonstrated by competent evidence prepared by the receiving Party) (collectively, the “Confidentiality Exceptions”). Notwithstanding
the foregoing, a receiving Party may use and disclose Confidential Information of the other Party (A) to the extent required by Applicable Law; provided, however, that if legally permissible, the receiving Party shall give the disclosing
Party advance written notice as promptly as is practicable to permit it to seek a protective order or other similar order, at the disclosing Party’s sole cost, with respect to the disclosure of such Confidential Information, and, thereafter,
the receiving Party shall disclose only the minimum Confidential Information that it is advised by counsel is required to be disclosed in order to comply; (B) to the extent such disclosure is reasonably necessary for the Prosecution and
Maintenance of Patents (including applications therefor) in accordance with Section 6.3, complying with the terms of the Dow Technology Assignment Agreement and Dow Technology Licensing Agreement (provided that Pfenex shall provide
Hospira with prior written notice of any such disclosure, including a copy of any such disclosure), prosecuting or defending litigation, conducting preclinical or clinical trials, or obtaining and maintaining regulatory approvals (including
Regulatory Approvals); (C) in communication with consultants and advisors (including financial advisors, lawyers and accountants) on a need to know basis, in each case, under appropriate confidentiality obligations substantially equivalent to
those of this Agreement (provided that the disclosing Party shall be responsible for any breach of this Section 8.1 by those Persons to which it discloses Confidential Information); or (d) to the extent mutually agreed to by the
Parties. 
 Section 8.2 Agents. Each of Pfenex and Hospira shall limit disclosure of the other Party’s
Confidential Information to only those of their respective existing or prospective Affiliates, directors, managers, officers, employees and contractors (collectively “Agents”) who are concerned with the performance of this
Agreement, have a legitimate need to know such Confidential Information in the performance of their duties and are bound by written obligations of non-use and non-disclosure at least as protective of the disclosing Party and its Confidential
Information as the terms hereof. Each Party shall be responsible for any breach of Section 8.1 by its Agents, consultants and advisors (including financial advisors, lawyers and accountants) and shall take all reasonably necessary
measures to restrain its Agents, consultants and advisors

(including financial advisors, lawyers and accountants) from unauthorized disclosure or use of the Confidential Information. 

Section 8.3 Restrictions on Sharing Information. 

(a)    Notwithstanding anything to the contrary, neither Party shall be obligated pursuant to this
Agreement to provide, or grant access to, any information (i) that it reasonably and in good faith considers to be Confidential Information it is prevented from disclosing to the other Party by an enforceable confidentiality agreement with a
Third Party and that such Party used Commercially Reasonable Efforts to obtain the consent of such Third Party to provide, or grant access to, such information to the other Party, (ii) the disclosure of which would adversely affect the
attorney-client privilege between such Party and its counsel, or (iii) the disclosure of which is not permitted pursuant to any Applicable Law or requirement of a Governmental Authority; provided, that in each case where information was
not provided or access was not granted as would otherwise be required under this Agreement, such Party shall inform the other Party of the reason it was not provided or granted and a description of the specific nature of the applicable information
and, in the case of clause (ii), such Party shall at the request of the other Party enter into a common interest agreement with the other Party to the extent such agreement would permit disclosure of such information without adversely affecting such
attorney-client privilege and then disclose such information to the other Party. Following the Effective Date and during the Term, in connection with entering into any material agreement (or material amendment thereof) with any Third Party related
to the Business, each Party agrees to use Commercially Reasonable Efforts to negotiate with such Third Party to include provisions in such agreement (or such amendment) sufficient to allow the other Party to receive relevant Confidential Information
of such Third Party. 
 (b)    This Agreement supersedes the Bilateral Confidential Disclosure
Agreement between the Parties dated August 31, 2014 (the “Prior Agreement”) with respect to information disclosed thereunder. All information exchanged between the Parties under the Prior Agreement shall be deemed Confidential
Information of the disclosing Party and shall be subject to the terms of Sections 8.1, 8.2 and 8.3.  

(c)    In addition to all obligations regarding the use of Hospira’s Confidential Information and
notwithstanding anything to the contrary herein, Pfenex shall not disclose any Confidential Information of Hospira with respect to the Development Plan or any Regulatory Materials (or any other Confidential Information of Hospira as reasonably
requested by Hospira from time to time) with any employees, independent contractors or consultants of Pfenex that are working on (or who have at any time worked on) the strategy for or preparation, prosecution or maintenance of any regulatory filing
for pegfilgrastim or application therefor, in each case pursuant to Pfenex’s collaboration with Strides Arcolab Limited and its affiliates. To the extent any such information is shared with any employees, independent contractors or consultants
of Pfenex, such individuals shall be prohibited from thereafter working on the strategy for or preparation, prosecution or maintenance of any regulatory filing for pegfilgrastim or application therefor, in each case pursuant to Pfenex’s
collaboration with Strides Arcolab Limited and its affiliates.

 Section 8.4    Taxes.  

(a)    Pfenex (or its permitted assignee) shall deliver to Hospira on or prior to the date of this
Agreement, and promptly upon request by Hospira, an accurate and complete originally signed IRS Form W-9 (or any successor or other applicable form prescribed by the Internal Revenue Service). In addition, Pfenex agrees that from time to time after
the date hereof, when a lapse in time (or change in circumstances occurs or any other reason) renders the prior IRS Form W-9 provided hereunder obsolete or inaccurate in any respect, Pfenex (or its permitted assignee) shall promptly deliver to
Hospira a new and accurate and complete originally signed IRS Form W-9 (or any successor or other applicable forms prescribed by the Internal Revenue Service). 

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

(c)    Any and all payments by or on account of any obligation of any Party under this Agreement shall be
made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of the applicable withholding Party) requires the deduction or withholding of any Tax from
any such payment by any Party, then the applicable Party shall be entitled to make such deduction or withholding, any amount so deducted or withheld shall be deemed paid to the other Party that was entitled to the payment subject to withholding,
shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law, and if such Tax is an Indemnified Tax, then the sum payable by the applicable Assignee shall be increased as necessary so
that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable recipient receives an amount equal to the sum it would have received had no
such deduction or withholding been made. Upon request by the other Party, such withholding Party shall deliver to the other Party that was entitled to the payment subject to withholding, the original or a certified copy of a receipt issued by such
Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the other Party. 

(d)    Any Assignee shall indemnify the Non-Assigning Party, within ten (10) days after demand
therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Non-Assigning Party or required to be withheld or deducted from
a payment to such Non-Assigning Party and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. Notwithstanding
anything to the contrary, if a Party or any Affiliate thereof (the “Tax Indemnified Party”) actually receives a refund, or obtains and actually utilizes a Tax credit to reduce a Tax liability, from any Governmental Authority for any

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

  
 48 








 
portion of any Indemnified Tax for which it was indemnified under this Section 8.4(d) by the other Party (the “Tax Indemnifying Party”), then the Tax Indemnified
Party shall promptly reimburse the Tax Indemnifying Party the amount of such refund or credit (but only to the extent of payments made under this Section 8.4(d) with respect to the Taxes giving rise to such refund or credit), net of all
out-of-pocket expenses (including Taxes) of such Tax Indemnified Party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund or credit); provided, however, that such Tax
Indemnifying Party, upon the request of such Tax Indemnified Party, shall repay to such Tax Indemnified Party the amount of refund or credit paid over pursuant to this sentence in the event that such Tax Indemnified Party is required to repay such
refund or credit to such Governmental Authority. Upon request by the Tax Indemnifying Party, the Tax Indemnified Party shall use Commercially Reasonable Efforts to obtain available refunds or credits with respect to any such Indemnified Taxes. 

(e)    All transfer, documentary, sales, use, excise, customs, charges, duties, ad valorem, value added,
stamp, registration, recording, property and other such similar Taxes (other than, for the avoidance of doubt, Taxes assessed against income), and all conveyance fees, recording charges and other fees and charges (including any penalties and
interest) lawfully assessed or charged in connection with any of the transactions contemplated under this Agreement (collectively, “Transfer Taxes”) shall be paid and borne 50% by Pfenex and 50% by Hospira when due, and the Party
responsible under such Applicable Law for paying such Transfer Taxes shall, at its own expense, file all necessary Tax returns and other documentation with respect to all such Transfer Taxes, and, if required by Applicable Law, the Parties will, and
will cause their Affiliates to, join in the execution of any such Tax returns and other documentation. 

(f)    The Parties acknowledge and agree that under current law no amount contemplated to be payable
under this Agreement by Hospira to Pfenex or by Pfenex to Hospira pursuant to this Agreement is subject to any withholding or deduction for Taxes. To the extent that as a result of any change in the Tax law of Bahamas, any payment to Pfenex pursuant
to this Agreement becomes subject to Bahamas withholding Tax, Hospira shall indemnify Pfenex, within ten (10) days after demand therefor, for the full amount of any withholding Taxes imposed by Bahamas on such payment (including Bahamas
withholding Tax imposed on amounts payable under this Section 8.4(f)). Notwithstanding anything to the contrary, if Pfenex or any Affiliate thereof actually obtains a refund or a credit from any Governmental Authority for any portion of
any Tax for which it was indemnified under this Section 8.4(f) by Hospira, Pfenex shall promptly reimburse Hospira the amount of such refund or credit; and, upon request by Hospira, Pfenex shall use Commercially Reasonable Efforts to
obtain available refunds or credits with respect to any such Taxes. 

Section 8.5    Nonsolicitation. Each Party (for purposes of this Section 8.5, a
“Soliciting Party”) agrees that, during the Term, such Soliciting Party will not solicit for employment or consultancy, employ or engage as a consultant or solicit the termination of employment or consultancy with the other
Party (a “Solicitation Action”), any individual that at the time of such Solicitation Action (a) is an officer or employee of the other Party or a consultant that is devoting a substantial majority of such individual’s
time to the business of the other Party and (b) is or was actively involved in the other Party’s performance of its obligations hereunder; provided,

treatment has been requested with respect to the omitted portions.

however, that the foregoing shall not prohibit (x) any advertisement or general solicitation (or hiring or engagement as a consultant as a result thereof) for employment or
consultancy not specifically directed at any such individual; (y) the hiring or engagement as a consultant of any such individual who initiates employment or consultancy discussions with such Soliciting Party; provided, that such initial
discussions are not encouraged or solicited by such Soliciting Party; or (z) any Solicitation Action with respect to any individual following the cessation of such individual’s employment with (or service as a consultant that is devoting a
substantial majority of such person’s time to the business of) the other Party without any solicitation or encouragement by such Soliciting Party.

(i), (ii) or (iii) of Section 11.1. 
 Section 11.3 Indemnification Procedure. 

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

(b)     If the Indemnifying Party does not object to any claim or claims made in the Indemnification
Notice in a written objection (the “Indemnification Objection”) prior to the expiration of twenty (20) Business Days from the Indemnifying Party’s receipt of the Indemnification Notice, the Indemnifying Party shall be
deemed not to object to the information contained within the Indemnification Notice.                     If the Indemnifying Party delivers an
Indemnification Objection within such twenty (20) Business Day period, the Indemnifying Party and the Indemnified Party shall attempt in good faith to resolve the dispute for twenty (20) Business Days after the Indemnifying Party’s
receipt of such Indemnification Objection. If no resolution is reached, the dispute shall be resolved in accordance with the provisions of Sections 10.6 and 13.4.  

(c)     The Indemnifying Party, if it so elects, may assume and control the defense of a Third Party
Claim at the Indemnifying Party’s expense and shall consult with the Indemnified Party with respect thereto, including the employment of counsel reasonably satisfactory to the Indemnified Party; provided, however, that the Indemnifying
Party shall not

have the right to assume control of such defense if the claim that the Indemnifying Party seeks to assume control of (i) seeks material non-monetary relief or (ii) involves criminal or
quasi-criminal allegations. If the Indemnifying Party is permitted to assume and control the defense of a Third Party Claim and elects to do so, the Indemnified Party shall have the right to employ counsel separate from counsel employed by the
Indemnifying Party in any such action and to participate in the defense thereof, but the fees and expenses of such counsel employed by the Indemnified Party shall be at the expense of the Indemnified Party unless (x) the Indemnifying Party has
specifically agreed in writing otherwise, (y) the Indemnified Party has been advised by outside counsel that a reasonable likelihood exists of a material legal conflict of interest between the Indemnifying Party and the Indemnified Party or
(z) the Indemnifying Party has failed to assume the defense and employ counsel (in which case the fees and expenses of the Indemnified Party’s counsel shall be paid by the Indemnifying Party if the Indemnifying Party otherwise has an
obligation to indemnify the Indemnified Party for the related Third Party Claim). If the Indemnifying Party has assumed the defense of a Third Party Claim in accordance with the terms hereof, the Indemnifying Party may not enter into a settlement or
consent to any judgment without the prior written consent of the Indemnified Party unless (A) such settlement or judgment involves monetary damages only, all of which will be paid, without limitation, by the Indemnifying Party, and no admission
of fault or culpability on behalf of any Indemnified Party, and (B) a term of the settlement or judgment is that the Person or Persons asserting such claim unconditionally and irrevocably release all Indemnified Parties from all liability with
respect to such claim; otherwise, the consent of the Indemnified Party shall be required in order to enter into any settlement of, or consent to the entry of a judgment with respect to, any claim (which consent shall not be unreasonably withhold,
delayed or conditioned). If the Indemnifying Party does not assume and/or is not controlling the defense of a Third Party Claim for any reason, then the Indemnified Party may retain counsel of its own choosing, at the expense of the Indemnifying
Party, and assume and control the defense of such Third Party Claim, and the Indemnifying Party shall have the right to employ counsel separate from counsel employed by the Indemnified Party in any such action and to participate in the defense
thereof, but the fees and expenses of such counsel employed by the Indemnifying Party shall be at the expense of the Indemnifying Party. The Indemnifying Party shall have no obligations with respect to any Losses resulting from the Indemnified
Party’s admission, settlement or other communication without the prior written consent of the Indemnifying Party (which shall not be unreasonably withheld, delayed or conditioned). 

Section 11.4 Limitations on Liability. EXCEPT AS ARISING OUT OF A FAILURE OF A PARTY TO PAY ANY AMOUNT OWED
HEREUNDER, OR ARISING AS THE RESULT OF THE FRAUD OR WILLFUL MISCONDUCT OR OMISSION BY A PARTY, OR ARISING FROM BREACH OF A PARTY’S CONFIDENTIALITY OBLIGATIONS IN SECTIONS 8.1-8.3 OR OBLIGATIONS UNDER SECTION 3.8 AND EXCEPT WITH
RESPECT TO OBLIGATIONS TO INDEMNIFY A PARTY UNDER SECTION 11.1 OR SECTION 11.2, NEITHER PARTY, NOR ANY OF THEIR RESPECTIVE AFFILIATES, DIRECTORS, MEMBERS, OFFICERS, EMPLOYEES, SUBCONTRACTORS OR AGENTS SHALL HAVE, UNDER ANY LEGAL THEORY
(INCLUDING CONTRACT, NEGLIGENCE AND TORT LIABILITY), ANY LIABILITY TO ANY OTHER PARTY FOR

ANY CONSEQUENTIAL, SPECIAL, INDIRECT, INCIDENTAL OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO BREACH OF THIS AGREEMENT. 

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

 ARTICLE XIII. 

MISCELLANEOUS 

Section 13.1 Force Majeure. No Party shall be held liable or responsible to the other Party nor be deemed to have
defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from the following causes beyond the reasonable control of the affected Party:
fire, floods, earthquake, tsunami, ice, tornado, hurricane, windstorm, eruption, explosion, sabotage or vandalism, embargoes, war, acts of war (whether war be declared or not), invasion, domestic or foreign terrorist act, act of a public enemy,
insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any Governmental Authority (each, an event of “Force Majeure”); provided, that such
affected Party shall provide the other Party with prompt notice of the circumstances surrounding such a material failure or delay and will use Commercially Reasonable Efforts to overcome the difficulties created thereby and to resume performance of
its obligations as soon as practicable. If the performance of any such obligation under this Agreement is delayed owing to such a Force Majeure for any continuous period of more than one hundred eighty (180) days, the Parties will consult with
respect to an equitable solution, including the possibility of the mutual termination of this Agreement. For the avoidance of doubt, the occurrence of an event of Force Majeure shall not relieve any Party from fulfilling any obligation required

party is entitled hereunder.

 PFENEX AND HOSPIRA ANNOUNCE COLLABORATION TO DEVELOP 

AND COMMERCIALIZE PROPOSED LUCENTIS® BIOSIMILAR 

SAN DIEGO and LAKE FOREST, Ill. February XX- Pfenex Inc. (NYSE MKT: PFNX), a clinical-stage biotechnology company engaged in the development of biosimilar therapeutics,
and Hospira, Inc., (NYSE: HSP), the world’s leading provider of injectable drugs and infusion technologies, and a global leader in biosimilars, today announced that the companies have entered into an agreement to exclusively develop and
commercialize for worldwide sales PF582, Pfenex’s biosimilar candidate to Genentech’s LUCENTIS® (ranibizumab injection). LUCENTIS had estimated global sales of approximately
$4 billion in 2014 and is part of the broader $6.7 billion intraocular anti-VEGF (vascular endothelial growth factor) therapeutic segment. 
 Under the terms of the
collaboration, Pfenex will receive an upfront payment of $51 million once the collaboration receives antitrust approval, and, over the next five years and beyond, will be eligible to receive a combination of development and sales-based milestone
payments up to an additional $291 million, and tiered double-digit royalty on net sales of the product. 
 Pfenex and Hospira will share the Phase 3 equivalence
clinical trial costs, and Hospira will be responsible for manufacturing and commercializing the product worldwide. The collaboration will be governed by an Executive Steering Committee consisting of equal representation from Pfenex and Hospira. The
agreement also allows for additional future product collaborations. 
 “We are extremely pleased to announce our collaboration with Hospira, a recognized world
leader in biosimilars. This collaboration further validates the product development strength and capability of Pfenex as we continue to advance our pipeline of biosimilar candidates,” said Bertrand Liang, chief executive officer, Pfenex Inc.

 Pfenex is currently conducting a Phase 1b/2a clinical trial where 24 patients have been randomized to receive monthly intraocular injections of PF582 or LUCENTIS
for 3 doses and

ongoing patient follow-up for 12 months. The clinical trial’s primary objective is to evaluate safety and tolerability of PF582, with secondary objectives including comparative
pharmacokinetic (PK) and pharmacodynamic (PD) evaluations to help demonstrate biosimilarity to LUCENTIS. 
 “We are excited to be entering this collaboration
with Pfenex for its biosimilar candidate to LUCENTIS, which we expect will expand Hospira’s biosimilars pipeline to include a new therapeutic area. Pfenex has established expertise in the development of biosimilars, leveraging its proprietary
expression technology together with differentiated bioanalytical characterization capabilities,” said Sumant Ramachandra, M.D., Ph.D., senior vice president, chief scientific officer, Hospira. “We look forward to working closely with the
Pfenex team to offer patients, physicians and healthcare systems a more affordable treatment option for retinal diseases.” 
 The agreement is subject to review
under the Hart-Scott-Rodino Antitrust Improvements Act.

Pfenex’s or Hospira’s future financial or operating performance. In some cases, you can identify forward-looking statements because they contain words such as “may,” “will,” “should,” “expects,”

 Exhibit C 

Alternative Dispute Resolution 

The Parties recognize that bona fide disputes as to certain matters may arise from time to time during the term of this
Agreement which relate to any Party’s rights and/or obligations. To have such a dispute resolved by this Alternative Dispute Resolution (“ADR”) provision, a Party first must comply with Section 10.6 of the Agreement
to which this is an exhibit. If the matter has not been resolved in accordance with such Section 10.6, a Party may initiate an ADR proceeding as provided herein. The Parties shall have the right to be represented by counsel in such a
proceeding. 
 1.     To begin an ADR proceeding, a Party shall provide written notice to the other
Party of the issues to be resolved by ADR in accordance with this Exhibit C. Within fourteen (14) days after its receipt of such notice, the other Party may, by written notice to the Party initiating the ADR, add additional issues to be
resolved within the same ADR. 
 2.     Unless either Party requests otherwise in writing within the
fourteen (14) day period described in Paragraph 1 above, the issue shall be resolved in accordance with the Fast Track Meditation and Arbitration Rules of Procedure as administered by CPR Institute for Dispute Resolution
(“CPR”) by a single arbitrator appointed in accordance with such rules and subject to the provisions of Paragraphs 10 – 13 below. Otherwise such dispute shall be resolved as described in Paragraphs 3 - 13 herein below. 

3.     Within twenty-one (21) days following receipt of the original ADR notice, the Parties shall
select a mutually acceptable neutral (the “Neutral”) to preside in the resolution of any disputes in this ADR proceeding. If the Parties are unable to agree on a mutually acceptable Neutral within such period, a Party may request
the President of the CPR, 366 Madison Avenue, 14th Floor, New York, New York 10017, to select a Neutral pursuant to the following procedures: 

(a)     The CPR shall submit to the Parties a list of not less than five
(5) candidates within fourteen (14) days after receipt of the request, along with Curriculum Vitae for each candidate. No candidate shall be an employee, director, or shareholder of any Party or any of their subsidiaries or Affiliates.
Each candidate submitted by the CPR shall (i) be an attorney licensed to practice law for at least twenty (20) years in the United States; and (ii) have material legal or business experience in the pharmaceutical industry. 

(b)     Such list shall include a statement of disclosure by each candidate of any
circumstances likely to affect his or her impartiality. 
 (c)     Each Party shall
number the candidates in order of preference (with the number one (1) signifying the greatest preference) and shall deliver the list to the CPR within seven (7) days following receipt of the list of candidates. If a Party believes a
conflict of interest exists regarding any of the candidates, that Party shall provide a written explanation of the conflict to the CPR along with its list showing its order of

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







 
preference for the candidates. Any Party failing to return a list of preferences on time shall be deemed to have no order of preference. 

(d)     If the Parties collectively have identified fewer than three (3) candidates
deemed to have conflicts, the CPR immediately shall designate as the Neutral the candidate for whom the Parties collectively have indicated the greatest preference. If a tie should result between two candidates, the CPR may designate either
candidate. If the Parties collectively have identified three (3) or more candidates deemed to have conflicts, the CPR shall review the explanations regarding conflicts and, in its sole discretion, may either (i) immediately designate as
the Neutral the candidate for whom the Parties collectively have indicated the greatest preference, or (ii) issue a new list of not less than five (5) candidates, in which case the procedures set forth in subparagraphs 2(a)–2(d) shall
be repeated. 
 4.     No earlier than forty-five (45) days or later than ninety (90) days
after selection, the Neutral shall hold a hearing to resolve each of the issues identified by the Parties. The ADR proceeding shall take place at a location agreed upon by the Parties. If the Parties cannot agree, the Neutral shall designate one of
the following four cities or its immediate environs: New York, New York; Atlanta, Georgia; Washington, D.C.; or Wilmington, Delaware. 

5.     At least fourteen (14) days prior to the hearing, each Party shall submit the following to the
other Party and the Neutral: 
 (a)     a copy of all exhibits on which such Party
intends to rely in any oral or written presentation to the Neutral; 
 (b)     a list of
any witnesses such Party intends to call at the hearing, and a short summary of the anticipated testimony of each witness; 

(c)     a proposed ruling on each issue to be resolved, together with a request for a
specific damage award or other remedy for each issue. The proposed rulings and remedies shall not contain any recitation of the facts or any legal arguments and shall not exceed one (1) page per issue. 

(d)     a brief in support of such Party’s proposed rulings and remedies;
provided, that the brief shall not exceed thirty (30) double-spaced pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. 

Except as expressly set forth in subparagraphs 4(a)–4(d), no discovery shall be required or permitted by any means, including
depositions, interrogatories, requests for admissions, or production of documents. 
 6.     The hearing
shall be conducted on consecutive days and shall be governed by the 
 following rules: 

(a) Each Party shall be entitled to ten (10) hours of hearing time to present its case. The Neutral shall
determine whether each Party has had the ten (10) hours to which it is entitled. 
  

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

 (b)     Each Party shall be entitled, but not
required, to make an opening statement, to present regular and rebuttal testimony, documents or other evidence, to cross-examine witnesses, and to make a closing argument. Cross-examination of witnesses shall occur immediately after their direct
testimony. Opening statements, closing statements, rebuttal testimony and cross-examination time shall be charged against the Party conducting same. 

(c)     The Party initiating the ADR shall begin the hearing and, if it chooses to make an
opening statement, shall address not only issues it raised but also any issues raised by the responding Party. The responding Party, if it chooses to make an opening statement, also shall address all issues raised in the ADR. Thereafter, the
presentation of regular and rebuttal testimony and documents, other evidence, and closing arguments shall proceed in the same sequence. 

(d)     Except when testifying, witnesses shall be excluded from the hearing until closing
arguments. 
 (e)     Settlement negotiations, including any statements made therein,
shall not be admissible under any circumstances. Affidavits prepared for purposes of the ADR hearing also shall not be admissible. Live videoconference or telephonic testimony will be permitted at the discretion of the Neutral. The Neutral shall
have sole discretion with regards to the exercise of its subpoena powers to compel the attendance of witnesses and the production of documents from Third Parties. As to all other matters, the Neutral shall have sole discretion regarding the
admissibility of any evidence. 
 7.     Within ten (10) days following completion of the hearing,
each Party may submit to the other Party and the Neutral a post-hearing brief in support of its proposed rulings and remedies; provided, that such brief shall not contain or discuss any new evidence and shall not exceed thirty
(30) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. 
 8.
    The Neutral shall rule on each disputed issue within twenty-one (21) days following completion of the hearing. Such ruling shall adopt in its entirety the proposed ruling and remedy of one of the Parties on each disputed
issue but may adopt one Party’s proposed rulings and remedies on some issues and the other Party’s proposed rulings and remedies on other issues. The Neutral shall not issue any written opinion or otherwise explain the basis of the ruling.

 9.     The Neutral shall be paid a reasonable fee plus expenses. These fees and expenses, along with
the reasonable legal fees and expenses of the prevailing Party (including all expert witness fees and expenses), the fees and expenses of a court reporter, and any expenses for a hearing room, shall be paid as follows: 

(a)     If the Neutral rules in favor of one Party on all disputed issues in the ADR, the
losing Party shall pay one hundred percent (100%) of such fees and expenses. 
 (b)
    If the Neutral rules in favor of one Party on some issues and the other Party on other issues, the Neutral shall issue with the rulings a written determination as to

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







 
how such fees and expenses shall be allocated between the Parties. The Neutral shall allocate fees and expenses in a way that bears a reasonable relationship to the outcome of the ADR, with the
Party prevailing on more issues, or on issues of greater value or gravity, recovering a relatively larger share of its legal fees and expenses. 

10.     The rulings of the Neutral and the allocation of fees and expenses shall be binding,
non-reviewable, and non-appealable to the extent allowed by Law, and may be entered as a final judgment in any court having jurisdiction. 

11.     Except as provided in paragraph 10 or as required by Applicable Law, the existence of the dispute,
any settlement negotiations, the ADR hearing, any submissions (including exhibits, testimony, proposed rulings, and briefs), and the rulings shall be deemed Confidential Information of both Parties. The Neutral shall have the authority to impose
sanctions for unauthorized disclosure of Confidential Information. 
 12.     The Neutral may not award
punitive damages. The Parties hereby waive the right to the award of punitive damages. 
 13.     The
hearings shall be conducted in the English language.
