Section 2.3(b). 

  

	 	b.	 Institute shall provide to Ambrx, within thirty (30) days following the approval of the applicable
Research Plan by the JSC, such JSC-approved Research Plan, including the identification of any Institute Controlled IP or Third Party Controlled intellectual property to be used in the Research Plan. Ambrx
shall have thirty (30) days following receipt of such Research Plan to review such Research Plan and shall have the right to reject such Research Plan or withhold access to the Ambrx Technology proposed to be used in such Research Plan if:
(i) Ambrx reasonably determines the applicable Proof of Concept Study is inappropriate for the proposed indication listed in the Research Plan when compared against other research projects or programs for the same or similar indications;
(ii) Ambrx reasonably determines the Research Plan and associated Collaboration Research Project is competitive with current or anticipated Ambrx projects (whether conducted or to be conducted on behalf of itself or a Third Party); or
(iii) the Ambrx CEO, or in the absence of a CEO, a majority of the Ambrx board of directors (excluding any member of the Ambrx board of directors having a conflict of interest with respect to such determination), determines to reject such
Research Plan or withhold access to the applicable Ambrx Technology, which the CEO (or Ambrx board of directors, as applicable) may determine in his/her (or its) sole discretion. A determination by Ambrx that the Research Plan falls within (i),
(ii) or (iii) above and whether Ambrx is rejecting the Research Plan in its entirety (in which case, for clarity, the license grant under Section 3.1 shall not be
applicable to such Research Plan and Institute shall not use any Ambrx funding provided hereunder in connection with further activities on such rejected Research Plan) or with respect to specified Ambrx Technology (in which case, for clarity, such
Ambrx Technology shall not be included in the license grant under Section 3.1 for the associated Research Plan) shall be provided in writing to Institute within the thirty (30)-day Ambrx review period and shall include such information to substantiate the determination as is reasonably necessary. 

 

	 	c.	 If Ambrx rejects the Research Plan with respect to specified Ambrx Technology (and does not reject the Research
Plan in its entirety), the Research Plan shall constitute an “Approved 

  
 Page 11 

	 	
Research Plan” in all aspects other than the Ambrx Technology rejected pursuant to Section 4.2(b)(iii).

 4.3 Amendment of Approved Research Plans. An Approved Research Plan may only be amended by
following the procedure set forth in Section 4.2 with respect to the proposed changes and/or updates, unless such proposed changes and/or updates are simply day-to-day or tactical changes or updates in which case the JSC may approve them. 

4.4 Conduct of Collaboration Research Projects. 

 

	 	a.	 The Parties intend that one or more of the Collaboration Research Projects are to be initiated on or about
thirty (30) days following the first meeting of the JSC, and that multiple Collaboration Research Projects will be ongoing at any given time during the Research Program Term. 

 

	 	b.	 Institute agrees that its activities under the Collaboration Research Projects shall be conducted by or under
the direct supervision of Peter Schultz, Ph.D. (“Schultz”). In the event that Schultz leaves Institute, or terminates his involvement with the Institute or a particular Collaboration Research Project, Institute shall
promptly notify Ambrx of such event. Thereafter Ambrx shall have a right to immediately terminate the Research Program Term upon delivery to Institute of written notice of intent to terminate pursuant to this
Section 4.4(b), which notice must be delivered to Institute not more than ninety (90) days after receipt by Ambrx of Institute’s notification. 

 

	 	c.	 Institute shall perform, and shall use reasonable efforts to ensure that its employees perform, its activities
with respect to the Collaboration Research Projects in good scientific manner, and in compliance in all material respects with the requirements of applicable law. Institute shall commit sufficient Research Plan FTEs to each Collaboration Research
Project to permit the timely completion of each Collaboration Research Project as set forth in the applicable Approved Research Plan. 

  

	 	d.	 Institute may not retain Third Parties (including, but not limited to, consultants or agents) to perform any
activities for a Collaboration Research Project without the prior written consent of Ambrx. 

  

	 	e.	 Upon the written request of the Institute, Ambrx (directly or indirectly) may in its sole discretion,
(i) with respect to an Approved Research Plan, (A) assist the Institute in certain activities (specifically for the advancement of the applicable Collaboration Research Project up to the applicable Proof of Concept Study (by way of
example, but not limitation, activities such as protein production, purification and analytics)); (B) validate, consider and develop Inventions after the applicable Proof of Concept Study; (C) assist the Institute in efforts to generate stable
cell lines based on Ambrx Materials; or (ii) with respect to an approved Institute Proposal, assist the Institute in connection with its activities under such Institute Proposal. The fully burdened costs associated with Ambrx activities under
subsections (i)(A), (i)(B) and (i)(C) incurred following the Effective Date will be borne entirely by Ambrx. Institute will reimburse Ambrx for its then-current fully-burdened FTE rate in connection with Ambrx activities requested by Institute under
subsection (ii). It is acknowledged and agreed by the Parties that any assistance provided by Ambrx to Institute pursuant to this Section 4.4(e) involves intensive activities and in the event of a high

  
 Page 12 

	 	
workload at Ambrx, Ambrx shall retain sole discretion to prioritize projects accordingly and may determine to discontinue any assistance under this
Section 4.4(e) or to not initiate any such assistance. 

 4.5
Invention Disclosures; Joint Inventions; Approved Research Inventions. 
  

	 	a.	 As soon as reasonably possible following the completion of the related Proof of Concept Study, but in no event
later than thirty (30) days thereafter, Institute shall provide a written Invention Disclosure describing all Inventions related to the Collaboration Research Project associated with the Proof of Concept Study to Ambrx. Any such Invention
Disclosure shall contain sufficient detail (as it is available to Institute) to enable Ambrx to evaluate the advisability of exercising the Option with respect to the related Inventions and to comply with the terms of the license granted to it under
Institute Technology pursuant to Section 3.5(a)(iii). 

  

	 	b.	 As soon as reasonably possible, either upon conception or reduction to practice, as the case may be, of each
Joint Invention, Ambrx shall disclose the same in writing to Institute. Such disclosure shall contain sufficient detail to enable Institute to evaluate whether such Invention is, in fact, within the definition of a Joint Invention. If Institute, in
the exercise of its good faith discretion, believes that all or some of such Information as so described by Ambrx does not fall within the definition of a Joint Invention, then Institute shall deliver to Ambrx a written notice identifying the
Invention(s) which Institute does not believe are Joint Invention(s) within thirty (30) days of receipt of the Invention Disclosure from Ambrx. Failure to deliver such a written notice within the thirty
(30)-day period shall be deemed to be an acknowledgement by Institute that such Invention(s) is a Joint Invention(s). Any dispute related to whether an Invention constitutes Joint Invention(s) shall be
resolved as set forth in Sections 14.2, 14.3 and 14.4. 

 

	 	c.	 If Ambrx decides to not exercise the Option for the exclusive license under Institute’s ownership interest
in an Invention Patent for a Joint Invention, then (i) both Institute and Ambrx shall jointly own such Invention Patent(s); and (ii) notwithstanding the foregoing, Institute and Ambrx hereby covenant and agree that, unless the other Party
consents in writing, they each shall practice such Invention Patent solely in the Field and neither shall license or Sublicense rights to any such Invention Patent without the other Party’s prior written consent (unless Ambrx has previously
exercised an Option for such Invention Patent). Except as set forth in this Section 4.5(c) , Ambrx shall be the only Party that may grant a commercial license or Sublicense to any Invention Patent for a
Joint Invention to a Third Party, and only pursuant to the exclusive license granted to Ambrx under Section 3.5(c) or following the exercise of the Option hereunder. Joint ownership
of a Joint Invention shall not include a license grant of any related or underlying technology or Patents, unless specifically set forth in Section 3.5(c) or in a separate license
agreement between the Parties. 

  

	5.	 Option 

5.1 Grant of Option. 
  

	 	a.	 Subject to the terms of this Agreement, Institute hereby grants to Ambrx an exclusive option (each, an
“Option”) to acquire (i) an exclusive worldwide license (or sublicense, as the case may be) to Inventions and Invention Patents, with an exclusive right to grant Sublicenses, for

  
 Page 13 

	 	
all uses and (ii) a non-exclusive worldwide license (or sublicense, as the case may be) to related Information and Institute Controlled IP, with a
right to grant Sublicenses, for all uses. Each such license shall be to the Inventions, Invention Patents and Institute Controlled IP disclosed under the Invention Disclosures associated with a specific Collaboration Research Project, as more
particularly described in the Invention Disclosures (Section 4.5). Such Option shall be for the period (Section 5.2) and
exercised (Section 5.3) as more particularly described below. For clarity, Excluded GRP Inventions are excluded and shall not be subject to the Option described in this
Article 5. 

 5.2 Option Period. 

 

	 	a.	 Subject to extension as set forth in
Section 5.2(b), Ambrx shall have a period of [***] ([***]) days from the later of (i) delivery by Institute of a written Invention Disclosure pursuant to
Section 4.5(a) and (ii) receipt of a data package requested by Ambrx (within thirty (30) days of receipt of the Invention Disclosure) with respect to the Invention, containing all data
relevant to Ambrx’s decision to exercise the Option and reasonably available to Institute, including, without limitation, materials, assays, reagents and protocols that may reasonably be requested and Information from the related Proof of
Concept Study (each, as the same may be extended pursuant to Section 5.2(b), an “Option Period”) to consider and/or validate the Invention Data Packages which may include
reasonably and promptly recapitulating the experimental results using materials provided by the Institute or produced and characterized at Ambrx, in animal models conducted at Ambrx or under the direct supervision of an Ambrx scientist. The
disclosures to be delivered to Ambrx under (ii) above shall be referred to herein as “Invention Data Packages.” 

  

	 	b.	 Ambrx is obligated to consider and/or validate [***] ([***]) Invention Data Packages in each Calendar Year
(whether or not the Invention Data Package is new or carried-over from the prior Calendar Year). If Ambrx has considered and validated [***] ([***]) Invention Data Packages disclosing Inventions in the applicable Calendar Year, the Option Period
with respect to an additional Invention Data Package shall automatically be extended through the end of the following Calendar Year (with multiple extensions of a single Option Period possible and with extensions beyond the Research Program Term
and/or term of this Agreement possible). In addition, an Option Period may be extended upon mutual written agreement of Institute and Ambrx. 

5.3 Exercise of Option. 
  

	 	a.	 Ambrx shall deliver to Institute written notice (each, an “Option Notice”)
within the Option Period specifying the particular Invention, Invention Patent and related Information, if any, described in the applicable Invention Disclosure and Invention Data Package and the Institute Controlled IP associated with such
Invention Data Package (collectively, the “Option IP”), and shall state whether Ambrx is exercising the Option or not with respect to the particular Option IP. 

 

	 	b.	 If Ambrx determines to exercise an Option with respect to particular Option IP, Ambrx shall have (i) a
perpetual, irrevocable, exclusive (even as to Institute) license (or sublicense, as the case may be), with the right to grant a Sublicense, under the particular Invention Patent(s), if any, to research, develop, make, have made, use, sell, offer for
sale, export and import the applicable Licensed Products for all uses throughout the world; (ii) a perpetual, irrevocable, 

  
 Page 14 

	 	
non-exclusive license (or sublicense, as the case may be), with the right to grant a Sublicense, under Patents included within the Institute Controlled IP
to research, develop, make, have made, use, sell, offer for sale, export and import the applicable Licensed Products for all uses throughout the world; and (iii) a perpetual, irrevocable, non-exclusive
license (or sublicense, as the case may be), with the right to grant a Sublicense, under Information directly related to such Invention Patents and Know-How included within the Institute Controlled IP to
research, develop, make, have made, use, sell, offer for sale, export and import the applicable Licensed Products for all uses throughout the world. Ambrx shall commit to pursue or have pursued products or services covered by Invention Patents
licensed to Ambrx using commercially reasonable efforts, and the Parties shall, upon the exercise of an Option, develop reasonable and specific milestones relevant to a Licensed Product(s), such milestones to be met by Ambrx, its Affiliates or its
Sublicensee(s) to continue the license thereunder. Such milestones may include, for example, investment requirements and timelines for major regulatory and commercialization milestones. In addition, if Ambrx determines to exercise an Option with
respect to Option IP described in an applicable Invention Disclosure and Invention Data Package arising out of a Grandfathered Research Project, Ambrx shall reimburse Institute the fully burdened expenses incurred by Institute for such Grandfathered
Research Project from inception to date that the work plan for the Grandfathered Research Project was approved by Ambrx at an FTE rate of [***] ([***]), provided such expenses don’t exceed [***] ([***]) per project, within thirty (30) days
of the exercise of such an Option. It is understood and agreed that following the exercise of an Option hereunder, Ambrx (or its Sublicensees) shall be the exclusive Party to develop and/or commercialize the applicable Invention Patents and related
Information, either itself or pursuant to a Sublicense. 

  

	 	c.	 If Ambrx exercises an Option with respect to particular Option IP and subsequently or concurrently determines
to Sublicense such Option IP, it shall deliver to Institute written notice of its determination to Sublicense (each, a “Sublicense Notice”). 

 

	 	d.	 If Ambrx determines not to exercise an Option with respect to particular Option IP as set forth in the
applicable Option Notice, the Option Notice shall so state. For clarity, the license grant set forth in Section 3.1 shall not cover the particular Option IP for which Ambrx has determined not to
exercise its Option and Institute hereby covenants and agrees that no funding provided by Ambrx hereunder shall be used by Institute if it determines to further pursue such rejected Option IP. Institute is free to pursue the rejected Option IP with non-Ambrx Technology and non-Ambrx Materials and its own funding. 

  

	6.	 Ongoing Development of Inventions 

6.1 Research and Development of Inventions by Ambrx. Following exercise of the Option with respect to particular Invention
Patent(s) and related Information, if any, Ambrx shall have exclusive control over the research, development and/or commercialization activities associated with such Invention Patent(s), and shall be exclusively responsible for all associated
research, development and commercialization expenses incurred by or on its behalf. In addition, following exercise of the Option with respect to particular Invention Patent(s) and related Information, if any, Ambrx shall reimburse Institute for its
Patent Prosecution Costs as set forth in Section 8.2(a). 
 6.2
Research and Development of Inventions by Institute. If Institute desires to further develop or have developed an Invention, then: 

  
 Page 15 

	 	a.	 If (i) the Option Period has expired and the Invention has not been exclusively licensed to Ambrx pursuant
to Section 5 above or (ii) the Invention has been exclusively licensed to Ambrx, and Ambrx (or any of its Affiliates) is not actively developing or is not actively
out-licensing (or has not previously out-licensed) such Invention, the Institute may present Ambrx with a proposal for the ongoing development and commercialization of
such Invention (the “Institute Proposal”). Any such Institute Proposal shall contain such information as is available to Institute and reasonably necessary for Ambrx to evaluate the Institute Proposal, including,
without limitation, (w) an overview of the intended development activities, (x) the projected commercial opportunity, (y) activities that Institute would assign to Ambrx, if any, and (z) commercial terms commensurate with the
proposed development and commercialization. 

  

	 	b.	 Within sixty (60) days of receipt of all requested information related to the Institute Proposal, the CEO
of Ambrx, or in the absence of a CEO, a subcommittee of the Ambrx board of directors, to be chaired by a member of such subcommittee selected by a majority vote of disinterested members of the Ambrx board of directors (the “Ambrx
Subcommittee”), shall review and reasonably consider the Institute Proposal. If the Ambrx CEO or Ambrx Subcommittee desires to proceed with the Institute Proposal, it shall oversee the negotiation and documentation of a license
agreement between Ambrx and Institute containing mutually acceptable terms and conditions, including financial terms, which shall include, without limitation, (i) a prohibition on Institute commercializing the Invention in any manner other than
by way of a Sublicense to a Third Party on arms-length, commercially reasonable terms, (ii) Institute shall commit to pursue or have pursued products or services covered by Invention Patents licensed to Institute using commercially reasonable
efforts, and (iii) the Parties shall develop reasonable and specific milestones relevant to a Licensed Product(s), such milestones to be met by Institute’s Sublicensee(s) to continue the license thereunder. Such milestones may include, for
example, reasonable investment requirements and timelines for major regulatory and commercialization milestones. In addition, the licenses granted under such license agreement may not be practiced directly by Institute or any of its Affiliates and
Institute may only commercialize the Invention by way of a Sublicense to a Third Party on arms-length, commercially reasonable terms.. It is the intent of the Parties that the review by Ambrx and the negotiation and documentation of a license
agreement take place within the sixty (60)-day period, unless mutually extended by the Parties. Once a license agreement between Ambrx and Institute is negotiated, the determination to proceed with the
Institute Proposal (or not) under such license agreement shall be made by the Ambrx CEO or Ambrx Subcommittee in his/its sole discretion. 

  

	 	c.	 In the event that Ambrx determines not to proceed with an Institute Proposal, and the development of the
relevant Invention would require a license from Ambrx with respect to Ambrx Technology, Institute may not develop the relevant Invention beyond animal proof of concept studies or commercialize such Invention without any such required licenses from
Ambrx with respect to the Ambrx Technology. In addition, Institute hereby covenants and agrees that no funding provided by Ambrx hereunder shall be used by Institute if it determines to further pursue such rejected Institute Proposal. Institute is
free to pursue the rejected Institute Proposal with non-Ambrx Technology and non-Ambrx Materials and its own funding. 

  
 Page 16 

 6.3 Research and Development Under Excluded Grandfathered Research Projects by
Institute.  
  

	 	a.	 If Institute desires to develop in human clinical trials and/or thereafter commercialize the inventions
consisting of therapeutic compositions of matter for compounds demonstrated to have utility or a new use under an Excluded Grandfathered Research Project with respect to the applicable target studied under such Excluded Grandfathered Research
Project (i.e., actually made and tested under such Excluded Grandfathered Research Project) (with respect to each Excluded Grandfathered Research Project (e.g., target), the “Excluded GRP
Inventions”) during the period beginning on August 23rd, 2013 and ending on the earlier of (a) October
10th, 2017 or (b) the initiation of GLP/IND-enabling studies with respect to each Excluded GRP Invention (the “Excluded GRP Invention
Option Period”), it shall provide written notice to Ambrx of such desire which shall include the applicable target and compositions of matter information related to such Excluded GRP Inventions (each, an
“Excluded GRP Invention Notice”). Upon Ambrx’s receipt of an Excluded GRP Invention Notice prior to the expiration of the Excluded GRP Invention Option Period, Institute shall
automatically, without any action on the part of Ambrx, be granted the following licenses: (i) a perpetual, irrevocable, worldwide, exclusive (even as to Ambrx) license (or sublicense, as the case may be), with the right to grant a Sublicense,
under Ambrx Patents, if any, with Valid Claims covering the Excluded GRP Inventions described in the applicable Excluded GRP Invention Notice to research, develop, make, have made, use, sell, offer for sale, export and import such Excluded GRP
Inventions for all uses; and (ii) a perpetual, irrevocable, worldwide, non-exclusive license (or sublicense, as the case may be), with the right to grant a Sublicense, under Information directly related
to such Ambrx Patents to research, develop, make, have made, use, sell, offer for sale, export and import such Excluded GRP Inventions for all uses. Upon the grant of the licenses under this
Section 6.3(a) Institute shall be the exclusive Party to develop and/or commercialize the Excluded GRP Inventions and solely by means of a Sublicense to a Third Party; provided that such
Third Party Sublicensee may not be a pharmaceutical company with headquarters in the People’s Republic of China, unless Ambrx has provided its prior written consent, which may be withheld in its sole discretion. The licenses granted under this
Section 6.3(a) may not be practiced directly by Institute or any of its Affiliates and Institute may only commercialize the Excluded GRP Inventions by way of a Sublicense to such a Third
Party on arms-length, commercially reasonable terms. Institute shall ensure that any such Excluded GRP Inventions licensed hereunder are pursued using commercially reasonable efforts, and all rights to the licensed Excluded GRP Inventions shall
revert to Institute in the event of the failure of a Third Party sublicensee to use commercially reasonable efforts in the development and/or commercialization of the Excluded GRP Inventions (in addition to upon the occurrence of other agreed-upon
termination events). The Parties shall develop reasonable and specific milestones relevant to the Excluded GRP Inventions, such milestones to be met by Institute’s Sublicensee(s) to continue the license thereunder. Such milestones may include,
for example, investment requirements and timelines for major regulatory and commercialization milestones. Institute shall also pay to Ambrx [***] of any Net Sublicense Revenue as set forth in
Section 7.2. The Parties shall negotiate in good faith and enter into a license agreement setting forth the terms contained in this
Section 6.3(a), and other customary terms and conditions. 

  

	 	b.	 If Institute does not deliver one or more Excluded GRP Invention Notices prior to the expiration of the
Excluded GRP Option Period, then all Excluded GRP Inventions under the Excluded Grandfathered Research Projects shall automatically become an Invention and 

  
 Page 17 

	 	
Institute shall promptly thereafter provide an Invention Disclosure to Ambrx for any such Invention. For clarity, if the Excluded GRP Option Period expires without the delivery of an Excluded GRP
Invention Notice, all Excluded GRP Inventions shall be subject to the Option process set forth in Section 5. 

  

	 	c.	 If, however, Institute has delivered one or more Excluded GRP Invention Notices, then: (i) upon delivery
of an Excluded GRP Invention Notice, any Excluded GRP Inventions for the target referenced in the Excluded GRP Invention Notice but which have not been described in such Excluded GRP Invention Notice shall automatically become Inventions and
Institute shall promptly after the delivery of the Excluded GRP Invention Notice provide Invention Disclosures to Ambrx for any such Inventions not described; and (ii) on expiration of the Excluded GRP Option Period, any Excluded GRP Inventions
not previously licensed to Institute under Section 6.3(a) shall automatically become Inventions and Institute shall promptly after the expiration of the Excluded GRP Option Period provide Invention
Disclosures to Ambrx for any such Inventions. For clarity, all Excluded GRP Inventions which have not been described in an Excluded GRP Invention Notice or licensed to Institute under Section 6.3(a)
shall be subject to the Option process set forth in Section 5. 

  

	7.	 Payments 

7.1 Research Program Costs. Within five (5) days of the Effective Date, Ambrx will pay to Institute an
amount equal to [***] as payment in advance for Institute’s activities pursuant to Approved Research Plans in the first partial calendar quarter following the Effective Date. Thereafter during the Research Program Term, Ambrx will make
quarterly payments in advance to Institute of [***] ([***]) on or before each October 1, January 1, April 1 and July 1 that occurs during the Research Program Term in consideration of Institute’s
activities pursuant to Approved Research Plans (each a “Research Funding Payment”); provided, however, the last payment made pursuant to this Section 7.1 shall be pro-rated to take into account the number
of days in the last partial calendar quarter included in the Research Program Term. 
 7.2 Net Sublicense Revenue. 

 

	 	a.	 Ambrx shall pay to Institute [***] ([***]) of any Net Sublicense Revenue resulting from Sublicenses executed by
Ambrx or its Affiliates. 

  

	 	b.	 Institute shall pay to Ambrx [***] ([***]) of any Net Sublicense Revenue resulting from Sublicenses executed by
Institute or its Affiliates of a Licensed Invention and/or Licensed Product arising from the [***] Excluded Grandfathered Research Project. Institute shall pay to Ambrx [***] ([***]) of any Net Sublicense Revenue resulting from Sublicenses executed
by Institute or its Affiliates arising from the [***] Excluded Grandfathered Research Project. For all other Sublicenses executed by Institute or any Affiliates under the licenses granted to Institute under Section 6.3, Institute shall pay to
Ambrx [***] ([***]) of any Net Sublicense Revenue resulting from such Sublicenses. 

  

	 	c.	 Any payments due under this Section 7.2 shall be made
within ninety (90) days of receipt of the Net Sublicense Revenue by the applicable Party. 

  
 Page 18 

 7.3 Royalties. 

 

	 	a.	 General. Subject to the other provisions of this
Section 7.3 and the other provisions of this Agreement, in consideration of the licenses granted by Institute to Ambrx pursuant to its exercise of the Option, if Ambrx (or its Affiliates) commercializes
a Licensed Product without a Sublicensee, Ambrx shall pay to Institute royalties of [***] ([***]) of Net Sales of such Licensed Product during the applicable Royalty Term (as defined in subsection (c) below) for such Licensed
Product. 

  

	 	b.	 One Royalty. For clarity, only one royalty shall be due to Institute with respect to the same unit of
Licensed Product, regardless of the number of Licensed Inventions contained therein. 

  

	 	c.	 Royalty Term. Royalties payable by Ambrx to Institute under
Section 7.3 shall be paid on an Licensed Product-by-Licensed Product and country-by-country basis until the later of (i) 10 years after first commercial sale of the applicable Licensed Product in such country, and (ii) expiration in such
country of the last Valid Claim of the last-to-expire Licensed Invention with claims that cover such Licensed Product (the “Royalty
Term”). Upon the expiration of the Royalty Term with respect to a Licensed Product in a country, Ambrx shall have a fully-paid-up perpetual license under
Section 5.3(b) for the making, using, selling, offering for sale and importing of such Licensed Product in such country. 

 

	 	d.	 Royalty Payments and Reports. All amounts payable to Institute pursuant to
Section 7.3 shall be paid within ninety (90) days after the end of the calendar quarter in which the applicable Net Sales were invoiced. Each payment of royalties shall be
accompanied by a royalty report providing a statement, on an Licensed Product-by-Licensed Product and
country-by-country basis, of: (a) the amount of gross sales invoiced during the applicable calendar quarter, (b) the amount of deductions from gross sales
taken in calculating Net Sales during the applicable calendar quarter, (c) the amount of Net Sales during the applicable calendar quarter, (d) a calculation of the amount of royalty payment due in U.S. dollars on such Net Sales for such
calendar quarter, and (e) the amount of withholding taxes, if any, required by applicable law to be deducted with respect to such royalties. 

7.4 Miscellaneous Payment Terms.  
  

	 	a.	 Payment Method. All payments due under this Agreement to Institute shall be made by bank wire
transfer in immediately available funds to an account designated by Institute. All payments hereunder shall be made in U.S. dollars. 

  

	 	b.	 Taxes. Institute will pay any and all taxes levied on account of all payments it receives under
this Agreement. If laws or regulations require that taxes be withheld with respect to any payments by Ambrx to Institute under this Agreement, Ambrx will: (i) deduct those taxes from the remittable payment, (ii) pay the taxes to the proper
taxing authority, and (iii) send evidence of the obligation together with proof of tax payment to Institute on a timely basis following that tax payment. Each Party agrees to cooperate with the other Party in claiming refunds or exemptions from
such deductions or withholdings under any relevant agreement or treaty which is in effect. In addition, the Parties shall cooperate in accordance with applicable law to minimize indirect taxes (such as value added tax, sales tax, consumption tax and
other similar taxes) in connection with this Agreement. 

  
 Page 19 

	 	c.	 Foreign Exchange. Conversion of sales recorded in local currencies to U.S. dollars shall be
performed in a manner consistent with Ambrx’s normal practices used to prepare its audited financial statements for internal and external reporting purposes. 

 

	 	d.	 Records. Ambrx shall keep, and shall cause its Affiliates and Sublicensees to keep, complete,
true and accurate books of accounts and records, including gross amounts invoiced and any deductions thereto in connection with calculation of Net Sales, sufficient to determine and establish the amounts payable under this Agreement, and compliance
with the other terms and conditions of this Agreement. Such books and records shall be kept reasonably accessible and shall be made available for inspection for a three (3) year period in accordance with
Section 7.4(e) below. 

  

	 	e.	 Inspection of Records. Upon reasonable prior notice, Ambrx shall permit an independent nationally
recognized certified public accounting firm (subject to obligations of confidentiality to Ambrx), appointed by Institute and reasonably acceptable to Ambrx, to inspect the audited financial records of Ambrx to the extent relating to payments to
Institute; provided that such inspection shall not occur more often than once per Calendar Year, unless a material error is discovered in such inspection in which case Institute shall have the right to conduct a more thorough inspection for
such period. If Institute, after inspecting the audited financial records of Ambrx, discovers material errors, then Ambrx shall permit an independent nationally recognized certified public accounting firm (subject to obligations of confidentiality
to Ambrx), appointed by Institute and reasonably acceptable to the Ambrx, to inspect the books and records described in Section 7.4(d); provided that such
inspection shall not occur more often than once per Calendar Year, unless a material error is discovered in such inspection in which case Institute shall have the right to conduct an additional audit for such period. Any inspection conducted under
this Section 7.4(e) shall be at the expense of Institute, unless such inspection reveals any underpayment of the royalties due hereunder for the audited period by at least [***]
([***]), in which case the full costs of such inspection for such period shall be borne by Ambrx. Any underpayment shall be paid by Ambrx to Institute within forty-five (45) days, and any overpayment shall be credited against future amounts due
by Ambrx to Institute. 

  

	8.	 Intellectual Property Matters 

8.1 Ownership. Subject to the licenses granted hereunder, each Party will own all Inventions (and Patents that claim such
Inventions) solely invented by or on behalf of it and/or its Affiliates and/or their respective employees, agents and independent contractors (as determined by US patent law) in the course of conducting activities under the Collaboration Research
Projects (collectively, “Sole Inventions”). Subject to the licenses granted hereunder, the Parties will jointly own all Inventions (and Patents that claim such Joint Inventions) jointly invented by or on behalf of them
and/or their respective Affiliates, employees, agents or independent contractors (as determined by US patent law) in the course of conducting activities under the Collaboration Research Projects (collectively, “Joint
Inventions”). Notwithstanding the foregoing, Institute shall, at Ambrx’s request, assign its entire right, title and interest in and to any Sole Invention or Joint Invention that constitutes an Ambrx Technology Invention to
Ambrx or Ambrx’s designee, and Institute hereby appoints Ambrx as its attorney in fact solely to make such assignments and authorizes Ambrx to make such assignments. In each case, Institute shall execute and deliver to Ambrx a deed(s) of such
assignment, in a mutually agreeable form, within thirty (30) days after the date the Invention Disclosure is provided hereunder. Ambrx shall be responsible for recording all such assignments and

  
 Page 20 

 
Institute and its successors and assigns shall reasonably cooperate with Ambrx’s efforts to do so, including satisfying the assignment and recording requirements of relevant patent offices.

 8.2 Patent Prosecution and Maintenance. 

 

	 	a.	 Ambrx shall Prosecute all Invention Patents with claims covering Ambrx Technology Inventions throughout those
jurisdictions that Ambrx and the Institute determine to file Inventions Patents (collectively, the “Territory”). Ambrx shall bear [***] of the Patent Prosecution Costs for such Invention Patent(s). For all other Invention
Patents, Institute shall, with Ambrx’s participation, draft, file, prosecute and maintain (including any oppositions, interferences, reissue proceedings, reexaminations and post-grant proceedings) such Invention Patents (including those with
claims covering any Joint Invention) throughout the Territory (such activities, on behalf of Institute or Ambrx, with respect to Invention Patents being the “Prosecution”, with the term “Prosecute”
having the corresponding meaning). Such Prosecution shall be handled by outside counsel mutually agreed upon by the Parties that will jointly represent the Parties (the “Patent Firm”). Institute (a) shall keep
Ambrx advised of the status of the actual and prospective filings of Invention Patents; (b) upon Ambrx’s written request, shall provide advance copies of any papers related to the Prosecution of such Invention Patent filings;
(c) shall give Ambrx an opportunity to review the text of the application before filing, shall consult with Ambrx with respect thereto and shall incorporate Ambrx’s reasonable comments into any such Invention Patent filing; (d) shall
supply Ambrx with a copy of the application as filed, together with notice of its filing date and serial number; and (e) shall promptly give notice to Ambrx of the grant, lapse, revocation, surrender, invalidation or abandonment of any
Invention Patent. Subject to Section 8.2(b) and (c), and until the exercise of an Option by Ambrx, Institute shall bear [***] ([***]) of the Patent Prosecution Costs
for such Invention Patents and shall have lead responsibility and decision making control for such Prosecution, including all decisions related to whether to file and/or continue to pursue and/or maintain any such Invention Patents. Following the
exercise of an Option by Ambrx, Ambrx shall bear [***] ([***]) of the Patent Prosecution Costs for the applicable Invention Patent(s) and pay [***] of past expenses (upon presentation of reasonable supporting documentation), subject to offset and
deduction, and shall have lead responsibility and decision-making control for Prosecution of such Invention Patent(s). For clarity, each Party will bear its own internal costs (i.e., those costs that are not Patent Prosecution Costs) with respect to
its Prosecution activities for such Invention Patents. 

  

	 	b.	 Cooperation; Sharing of Information. The Parties will keep each other informed with regard to
Prosecution hereunder and will cooperate in the Prosecution of the Invention Patents in all respects. Each Party will provide the other Party all reasonable assistance and cooperation in such Prosecution efforts, including providing any necessary
powers of attorney, executing any other required documents or instruments for such Prosecution, and obtaining the assistance and cooperation of any Third Party licensors, as necessary to Prosecute the Invention Patents. Each Party will provide the
other Party with copies of any documents it receives or prepares in connection with such Prosecution and will inform the other Party of the progress of it. 

  

	 	c.	 Ambrx Right to Prosecute and Maintain. In the event that Institute elects not to Prosecute in any
country any Invention Patent, Institute will give Ambrx at least thirty (30) days’ notice before any relevant deadline and provide to Ambrx information it reasonably requests

  
 Page 21 

	 	
relating to the Invention Patent. Ambrx will then have the right to assume responsibility, using patent counsel of its choice, for the Prosecution of such Invention Patent in such country. If
Ambrx assumes responsibility for the Prosecution for any such Invention Patents as set forth above, then the Patent Prosecution Costs incurred by Ambrx in the course of such Prosecution will thereafter be borne by Ambrx, subject to offset and
deduction. 

  

	 	d.	 Ambrx Right to Delegate. Ambrx may delegate its rights and responsibilities as to a
particular Invention Patent to a Third Party, pursuant to an agreement with such Third Party. 

 8.3
Infringement Actions. 
  

	 	a.	 Infringement. The Parties will promptly notify each other of any actual, threatened, alleged or
suspected infringement by a Third Party of the Invention Patents (an “Infringement”). A notice under 42 U.S.C. 262(l) (however such section may be amended from time to time during the term of this Agreement) with respect to a
Licensed Product will be deemed to describe an act of Infringement, regardless of its content. As permitted by applicable law, each Party will promptly notify the other Party in writing of any such Infringement of which it becomes aware, and will
provide evidence in such Party’s possession demonstrating such Infringement. In particular, each Party will notify and provide the other Party with copies of any allegations of patent invalidity, unenforceability or non-infringement of any Invention Patents (including methods of use or manufacture thereof). Such notification and copies will be provided by the Party receiving such certification to the other Party as soon as
practicable and, unless prohibited by applicable law, at least within five (5) days after the receiving Party receives such certification. Such notification and copies will be sent by facsimile and overnight courier to the Parties at the
addresses specified in Section 14.11. 

  

	 	b.	 Ambrx Rights. Ambrx will have the first right, but not the obligation, to bring and control, at
its expense, an appropriate suit or other action before any government or private tribunal against any person or entity allegedly engaged in any Infringement (an “Infringement Action”) to remedy the Infringement (or to
settle or otherwise secure the abatement of such Infringement) of an Invention Patent for which Ambrx has exercised the Option pursuant to Section 5.3 or an Invention Patent with
claims covering Ambrx Technology Inventions. The foregoing right of Ambrx shall include the right to perform all actions of a reference product sponsor set forth in 42 U.S.C. 262(l). Institute will have the right, at the reasonable expense of Ambrx,
to be represented by counsel of its choice, in any Infringement Action with respect to an Invention Patent for which Ambrx has exercised the Option pursuant to Section 5.3. At
Ambrx’s request, Institute will join any Infringement Action as a party and will use commercially reasonable efforts to cause any applicable Third Party to join such Infringement Action as a party (all at Ambrx’s expense) if doing so is
necessary for the purposes of establishing standing or is otherwise required by applicable law to pursue such action. Institute will provide to Ambrx reasonable assistance in such enforcement, at Ambrx’s request and expense, including joining
such action as a party plaintiff if required by applicable law to pursue such action. Ambrx will keep Institute regularly informed of the status and progress of such enforcement efforts, and will reasonably consider Institute’s comments on any
such efforts. In any such action, Institute will not be named as the first party to a lawsuit. 

  

	 	c.	 Settlement. Without the prior written consent of the other Party (not to be unreasonably
withheld, conditioned or delayed), neither Party will settle any Infringement Action in any 

  
 Page 22 

	 	
manner that would adversely affect an Invention Patent, or that would limit or restrict the ability of a Party (or its Affiliates or Sublicensees, as applicable) to sell Licensed Products
anywhere in the world; provided, however, Ambrx may settle any Infringement Action related to an Invention Patent with claims covering an Ambrx Technology Invention in its sole discretion. 

 

	 	d.	 Expenses and Recoveries. Ambrx will be solely responsible for any expenses incurred by either of
the Parties as a result of an Infringement Action. If Ambrx recovers monetary damages from a Third Party in such Infringement Action, such recovery will first be applied to all
out-of-pocket costs and expenses incurred by the Parties in connection therewith, including attorneys’ fees. If such recovery is insufficient to cover all such
costs and expenses of both Parties, it will be shared pro-rata in proportion to the relative amount of such costs and expenses incurred by each Party. If after such reimbursement any funds remain from such
damages, such remaining funds will be retained [***] ([***]) by Ambrx and [***] ([***]) by Institute; provided, however, Ambrx shall retain [***] ([***]) of any remaining funds from an Infringement Action related to an Invention Patent with
claims covering an Ambrx Technology Invention. 

  

	 	e.	 Institute Rights. In the event Ambrx does not elect to pursue an action pursuant to
Section 8.3(b), Institute shall have the sole right to pursue infringement at its sole expense other than any infringement of an Invention Patent with claims covering an Ambrx
Technology Invention, and shall be entitled to any recovery therefrom. At Institute’s request, Ambrx will join any such Infringement Action as a party and will use commercially reasonable efforts to cause any applicable Third Party to
join such Infringement Action as a party (all at Institute’s expense) if doing so is necessary for the purposes of establishing standing or is otherwise required by applicable law to pursue such action. Ambrx will provide to Institute
reasonable assistance in such enforcement, at Institute’s request and expense, including joining such action as a party plaintiff if required by applicable law to pursue such action. In any such action, Ambrx will not be named as the first
party to a lawsuit. 

  

	9.	 Additional Obligations 

9.1 Institute Research Project Reports. Institute shall deliver to Ambrx a report as to each Invention and the activities
completed in the prior six (6) month period for each Collaboration Research Project (“Research Project Report”). Each Research Project Report shall specify for each Collaboration Research Project (a) a detailed
description of the research and development efforts undertaken by the Institute, (b) the current status of such efforts, (c) the estimated schedule and plan for such future efforts, (d) the individual responsible for the
Institute’s report, (e) all related Information, a detailed description of all procedures and the Ambrx Technology used and (f) such other matters as Ambrx reasonably requests. The reports shall be delivered on or about
January 1 and July 1 of each Calendar Year. In addition, Ambrx may request from time-to-time on thirty (30) days’ prior written notice that the
Parties meet to discuss the progress and status of Collaboration Research Projects. In addition, Institute shall deliver to Ambrx off-cycle Research Project Reports upon the reasonable request of Ambrx,
covering the period of time specified by Ambrx and providing the information set forth above with respect to each Collaboration Research Project. All Information submitted to Ambrx by Institute under this
Section 9.1 may be used by Ambrx pursuant to the licenses granted in Section 3.5, and for the purpose of evaluating whether or not to exercise the Option
to obtain the additional license pursuant to Section 5 hereof, as and when such Option is exercisable in accordance with the terms hereof. Ambrx shall not, during the term of this Agreement or

  
 Page 23 

 
after the termination hereof, disclose any of the Institute’s Confidential Information contained in a Research Project Report, unless and until (i) Ambrx is permitted to do so pursuant
to the terms of this Agreement or any license agreement entered into by Ambrx and Institute after exercise of the Option for such Invention or (ii) such Information is no longer within the definition of “Confidential Information” as
set forth in Section 11 herein. 
 9.2 Indemnity. Following exercise of
the Option, Ambrx hereby agrees to indemnify, defend and hold harmless Institute and any Affiliate and their trustees, officers, employees, scientists and agent from and against any liability or expense arising from any claims arising from
Ambrx’s use of any Licensed Inventions pursuant to this Agreement. Such indemnity and defense obligation shall apply to any product liability claims, including without limitation, personal injury, death, or property damage made by employees,
subcontractors, sublicensees or agents of Ambrx, as well as any member of the general public. 
 9.3 Limitation of Liability.
EXCEPT FOR (A) INDIRECT, INCIDENTAL, SPECIAL, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES PAID OR PAYABLE TO A THIRD PARTY BY AN INDEMNIFIED PARTY FOR WHICH THE INDEMNIFIED PARTY IS ENTITLED TO INDEMNIFICATION HEREUNDER AND/OR
(B) A BREACH OF SECTION 11, IN NO EVENT SHALL ANY PARTY, ITS DIRECTORS, OFFICERS, EMPLOYEES, AGENTS OR AFFILIATES BE LIABLE TO ANY OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES,
WHETHER BASED UPON A CLAIM OR ACTION OF CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY OR OTHER TORT, OR OTHERWISE, ARISING OUT OF THIS AGREEMENT. 

  
 Page 24 

 9.4 Insurance. Institute and Ambrx shall each procure and maintain insurance,
including (as to Ambrx) product liability insurance, with respect to its respective Collaboration Research Project activities and which are consistent with normal business practices of prudent companies similarly situated to such Party throughout
the term of this Agreement. A Party shall provide the other Party with written evidence of such insurance upon request and with written notice at least thirty (30) days prior to the cancellation,
non-renewal or material change in such insurance. 
  

	10.	 Limited Warranty.  

10.1 Each of Ambrx and Institute hereby represents and warrants that it has full right and power to enter into and perform its obligations
under this Agreement. 
 10.2 Institute hereby represents and warrants that Exhibit A sets forth a complete and accurate list
of all Ambrx Materials in its possession prior to or as of the Effective Date. 
 10.3 EXCEPT AS SET FORTH IN THIS SECTION 10,
NEITHER INSTITUTE NOR AMBRX MAKE ANY OTHER WARRANTIES CONCERNING TECHNOLOGY COVERED BY THIS AGREEMENT, INCLUDING WITHOUT LIMITATION, ANY EXPRESS OR IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. NEITHER INSTITUTE NOR AMBRX
MAKE ANY WARRANTY OR REPRESENTATION AS TO THE VALIDITY OR SCOPE OF PATENTS, OR THAT ANY COMPOUND AND/OR LICENSED PRODUCT WILL BE FREE FROM AN INFRINGEMENT ON PATENTS OR OTHER INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES, OR THAT NO THIRD PARTIES
ARE IN ANY WAY INFRINGING OR MISAPPROPRIATING TECHNOLOGY COVERED BY THIS AGREEMENT. 
  

	11.	 Confidentiality and Publication 

11.1 Treatment of Confidential Information. Each Party agrees that, during the term of this Agreement, and for a period of seven
(7) years after this Agreement terminates, a Party receiving Confidential Information of the other Party (the “Receiving Party”) will (i) maintain in confidence such Confidential Information to the same
extent the disclosing Party (the “Disclosing Party”) maintains its own proprietary information, (ii) not disclose such Confidential Information to any Third Party without the prior written consent of the
Disclosing Party and (iii) not use such Confidential Information for any purpose except those permitted by this Agreement, except for that portion of such Confidential Information that the Receiving Party can demonstrate by competent written
proof: 
  

	 	a.	 was already known to the Receiving Party or any of its Affiliates, other than under an obligation of
confidentiality to the Disclosing Party, at the time of disclosure by the Disclosing Party; 

  

	 	b.	 was generally available to the public or otherwise part of the public domain at the time of its disclosure to
the Receiving Party; 

  

	 	c.	 became generally available to the public or otherwise part of the public domain after its disclosure and other
than through any act or omission of the Receiving Party in breach of this Agreement; 

  

	 	d.	 is subsequently disclosed to the Receiving Party or any of its Affiliates by a Third Party without obligations
of confidentiality to the Disclosing Party with respect thereto; or 

  
 Page 25 

	 	e.	 is subsequently independently discovered or developed by the Receiving Party or its Affiliate without the aid,
application, or use of Confidential Information of the Disclosing Party. 

 11.2 Authorized Disclosure. Each
Party may disclose Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary in the following situations: 
  

	 	a.	 filing or prosecuting Patents in accordance with Article 8; 

 

	 	b.	 regulatory filings and other filings with governmental authorities (including regulatory authorities),
including filings with the U.S. Food and Drug Administration, as necessary for the development and/or commercialization of a Licensed Product, as required in connection with any filing, application or request for Regulatory Approval;
provided, however, that reasonable measures will be taken to assure confidential treatment of such information; 

  

	 	c.	 prosecuting or defending litigation; 

 

	 	d.	 complying with applicable law, including regulations promulgated by securities exchanges;

  

	 	e.	 disclosure to its Affiliates, employees, agents, independent contractors, licensors and any Sublicensees only
on a need-to-know basis and solely in connection with the performance of this Agreement, provided that each disclosee must be bound by obligations of
confidentiality and non-use at least equivalent in scope to and no less restrictive than those set forth in this Article 11 prior to any such disclosure; and 

 

	 	f.	 disclosure of the material terms of this Agreement, the state of development of Licensed Products, certain
blinded data generated under this Agreement, in each case to any bona fide potential or actual investor, stockholder, investment banker, acquirer, merger partner or other potential or actual financial partner; provided that each disclosee
must be bound by obligations of confidentiality and non-use at least equivalent in scope to and no less restrictive than those set forth in this Article 11 prior to any such disclosure.

 Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s
Confidential Information, it will, except where impracticable, give reasonable advance notice to the other Party of such disclosure and use reasonable efforts to secure confidential treatment of such information. In any event, the Receiving Party
agrees to take all reasonable action to avoid disclosure of Confidential Information of the Disclosing Party hereunder. 
 Nothing in
Section 11.1 or 11.2 shall limit a Party in any way from disclosing to any Third Party such Party’s U.S. or foreign income tax treatment and
the U.S. or foreign income tax structure of the transactions relating to such Party that are based on or derived from this Agreement, as well as all materials of any kind (including opinions or other tax analyses) relating to such tax treatment or
tax structure, except to the extent that nondisclosure of such matters is reasonably necessary in order to comply with applicable securities laws. 

11.3 Publications. Institute agrees that Ambrx shall have a right to publish Ambrx Confidential Information in its sole
discretion. Ambrx recognizes that the Institute has a legitimate interest in the public communication of scientific results. Therefore, it is anticipated that the Institute may wish to publish the results of the Collaboration Research Projects.
Ambrx will permit such publication provided that Ambrx is given a reasonable period, not less than thirty (30) days prior to the submission for publication of any 

  
 Page 26 

 
manuscript concerning the results of the Collaboration Research Projects, to review such manuscript to make certain that none of Ambrx’s Confidential Information is disclosed therein and to
enable Ambrx to file or cause to be filed any relevant patent applications prior to publication. Ambrx may request the delay of any such proposed publication for an additional sixty (60) day period, in order to file any patent applications on
the Inventions disclosed therein. Ambrx reserves the right to have any of Ambrx’s Confidential Information deleted from such manuscript. 

11.4 Publicity. Except as otherwise provided herein or required by law, neither Ambrx nor Institute shall originate any
publication, news release or other public announcement, written or oral, whether in the public press, stockholders’ reports, or otherwise, relating to this Agreement or to any Sublicense hereunder, or to the performance hereunder or any such
agreements, without the prior written approval of each other party. Scientific publications published in accordance with Section 11.3 of this Agreement shall not be construed as
publicity governed by this Section 11.4. 
  

	12.	 Term and Termination 

12.1 Term. Unless terminated sooner in accordance with the terms set forth herein, this Agreement, and the licenses granted
hereunder, shall expire when the last of the payment obligations under this Agreement have expired. 
 12.2 Termination Upon
Default. Any one or more of the following events shall constitute an event of default hereunder: (i) the failure of a Party to pay any amounts when due hereunder or (ii) the failure of a Party to perform any material obligation
required of it to be performed hereunder, and the failure to cure within sixty (60) days after receipt of notice from the other Party specifying in reasonable detail the nature of such default. Upon the occurrence of an event of default, the non-defaulting Party may deliver to the defaulting Party written notice of intent to terminate, such termination to be effective upon the date set forth in such notice. Such termination rights shall be in addition
to and not in substitution for any other remedies that may be available to the non-defaulting Party serving such notice against the defaulting Party. Termination pursuant to this
Section 12.2 shall not relieve the defaulting Party of liability and damages to non-defaulting Party for breach of this Agreement. Waiver by
any Party of a single default or a succession of defaults shall not deprive such Party of any right to terminate this Agreement arising by reason of any subsequent default. 

12.3 Termination Upon Ambrx Change of Control. Either Party may terminate this Agreement upon thirty (30) days’ prior
written notice delivered following the closing of an Ambrx Change of Control which occurs during the Research Program Term. If Ambrx terminates this Agreement following an Ambrx Change of Control, (i) Institute may continue to exercise the
research license granted pursuant to Section 3.1, on an Approved Research Plan-by-Approved Research Plan basis, for a
period of twenty four (24) months following the date of approval by Ambrx of the applicable Research Plan (such continued Research Plans, a “Continued Research Plan”) and (ii) Ambrx shall make [***]
([***]) [***] Research Funding Payments. Article 5 shall remain in effect with respect to any Inventions, Invention Patents and related Information that arise under or are conceived with respect to the Continued Research Plans, with
the exception that Ambrx may not exercise its Option with respect to any such Continued Research Plan Invention Patents and related Information. In addition, for clarity, following a termination under this
Section 12.3, no new Research Plans may be proposed for approval or initiated; and if Ambrx has previously exercised an Option with respect to particular Option IP, the licenses granted to Ambrx
pursuant to the exercise of such Option shall remain in full force and effect. For purposes of this Section 12.3, “Ambrx Change of Control” means (a) the acquisition by any
individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended) (a “Specified Person”) of beneficial ownership (within the

  
 Page 27 

 
meaning of Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended) of fifty percent (50%) or more of either (i) the then
outstanding shares of capital stock of Ambrx (the “Outstanding Common Stock”) or (ii) the combined voting power of the then outstanding voting securities of Ambrx entitled to vote generally in the election of
directors of Ambrx (the “Outstanding Voting Securities”); provided, however, that for the purposes of this subsection (a), the following acquisitions of securities of Ambrx shall not constitute an Ambrx Change
of Control: (w) any acquisition by existing stockholders of Ambrx, (x) any acquisition by Ambrx, (y) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by Ambrx or any corporation controlled by
Ambrx or (z) any acquisition by any corporation pursuant to a transaction which complies with clauses (i) and (ii) of subsection (b) of this definition; (b) the consummation of any acquisition, merger or consolidation
involving any Third Party (a “Business Combination Transaction”), unless immediately following such Business Combination Transaction, (i) the individuals and entities who were the beneficial owners, respectively,
of the Outstanding Common Stock and Outstanding Voting Securities immediately prior to such Business Combination Transaction beneficially own, directly or indirectly, fifty percent (50%) or more of, respectively, the then outstanding shares of
common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation or other entity resulting from such Business Combination Transaction
(including a corporation which as a result of such transaction owns the then-outstanding securities of Ambrx or all or substantially all of Ambrx’s assets either directly or through one or more subsidiaries) in substantially the same
proportions as their ownership, immediately prior to such Business Combination Transaction, of the Outstanding Common Stock and Outstanding Voting Securities, as the case may be and (ii) fifty percent (50%) or more of the members of the board
of directors of the corporation resulting from such Business Combination Transaction were members of the Board of Directors of Ambrx at the time of the execution of the initial agreement, or of the action of the Board of Directors of Ambrx,
providing for such Business Combination Transaction; or (c) Ambrx or any of its Affiliates sells or transfers to any Specified Person(s) in one or more related transactions properties or assets representing all or substantially all of
Ambrx’s business or assets at the time of such sale or transfer. 
 12.4 Expiration or Termination. 

 

	 	a.	 Upon the expiration of this Agreement, or upon a termination of this Agreement, each Party shall perform all
obligations incurred up to the date of said expiration or termination, and the Parties shall continue to abide by their non-disclosure obligations described in
Section 11. 

  

	 	b.	 Any licenses in effect as a result of exercises of Options hereunder shall remain in full force and effect and
Ambrx shall be obligated to make payments to Institute as set forth in Article 7 and Sections 6, 8, 9 (excluding Section 9.1), 10, and this
Section 12.4 shall survive and apply after expiration or termination of this Agreement. 

  

	 	c.	 Ambrx shall have the right to continue to consider and/or validate any Invention and related Information which
have not been considered and validated prior to the expiration or termination of this Agreement. Until the Option Period has expired with respect to any such remaining Inventions, Articles 5, 7, 8, 9 and 10 and
Sections 4.5, 6.1 and 6.2 of this Agreement shall remain in full force and effect with respect to such Inventions. 

  

	 	d.	 Ambrx’s right to license an Invention and related Information continues in perpetuity following the
expiration or termination of this Agreement, subject to compliance with the terms (including the payment terms) set forth in this Agreement. 

  
 Page 28 

	 	e.	 In the event of termination of the Research Program Term prior to the expiration of eighteen (18) months
following the Effective Date, Ambrx shall continue to make the quarterly Research Funding Payments set forth in Section 7.1 through the remainder of the eighteen (18) month period; provided,
that no such Research Funding Payments shall be made if Ambrx terminates this Agreement pursuant to Section 12.2 as a result of an uncured Institute default; provided further, that only the
Research Funding Payments set forth in Section 12.3(ii) shall be made if Ambrx terminates this Agreement pursuant to Section 12.3. 

 

	 	f.	 Any licenses in effect pursuant to Section 6.3 shall remain in
full force and effect and Institute shall be obligated to make payments to Ambrx as set forth therein and Articles 8, 9 (excluding Section 9.1), 10, and this
Section 12.4 shall survive and apply after expiration or termination of this Agreement. 

  

	 	g.	 Notwithstanding anything to the contrary, the following provisions shall survive and apply after expiration or
termination of this Agreement: Sections 3.5, 3.7, and 3.8 and Articles 1 (to the extent necessary to interpret other surviving sections), 13 and 14. All provisions
not surviving in accordance with this Section 12.4 shall terminate upon expiration or termination of this Agreement and be of no further force and effect. 

 

	13.	 Assignment; Successors 

13.1 Assignment. This Agreement may not be assigned by a Party without the prior written consent of the other
Party; provided, however, that Ambrx may assign this Agreement and its rights and obligations hereunder to a successor in interest to all or substantially all of the assets of Ambrx to which this Agreement relates, whether by way of a merger,
consolidation, sale of assets, change of control or similar transaction. 
 13.2 Binding Upon Successors and
Assigns. Subject to the limitations on assignment herein, this Agreement shall be binding upon and inure to the benefit of any successors in interest and assigns of Ambrx and Institute. 

 

	14.	 General Provisions 

14.1 Independent Contractors. The relationship between Ambrx and Institute is that of independent contractors.
Ambrx and Institute are not joint venturers, partners, principal and agent, master and servant, employer or employee, and have no other relationship other than independent contracting parties. Ambrx and Institute shall have no power to bind or
obligate each other in any manner, other than as is expressly set forth in this Agreement. 
 14.2 Disputes.
Ambrx and Institute recognize that disputes as to certain matters may from time to time arise during the term of this Agreement which relate to Ambrx’s and Institute’s rights and/or obligations hereunder. It is the objective of Ambrx and
Institute 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. To accomplish this objective, Ambrx and Institute agree to follow
the procedures set forth in Sections 14.3 and 14.4 if and when a dispute arises under this Agreement. 

14.3 Alternative Dispute Resolution. Any dispute controversy or claim arising out of or relating to the validity,
construction, enforceability or performance of this Agreement, including disputes 

  
 Page 29 

 
relating to alleged breach or to termination of this Agreement or the scope of this arbitration provision, shall be settled by binding Alternative Dispute Resolution
(“ADR”) in the manner described below: 
  

	 	a.	 If a Party intends to begin an ADR to resolve a dispute, after an initial 30 day waiting period after any such
dispute arises in which the relevant parties shall work reasonably and in good faith to amicably resolve the dispute without resorting to this article, such Party shall provide written notice (the “ADR Request”) to
counsel for the other Party informing such other Party of such intention and the issues to be resolved. From the date of the ADR Request and until such time as any matter has been finally settled by ADR, the running of the time periods contained in
Section 12.2 as to which party must cure a breach of this Agreement shall be suspended as to the subject matter of the dispute. 

 

	 	b.	 Within thirty (30) business days after the receipt of the ADR Request, the other Party, may, by written
notice to the counsel for the party initiating ADR, add additional issues to be resolved. 

 14.4
Arbitration Procedure. The ADR and all pre-hearing, hearing and post-hearing arbitration procedures, shall be conducted in English pursuant to the Commercial Arbitration Rules of the American
Arbitration Association for Large, Complex Cases then in effect (the “Rules”), as amended by the following provisions. 
  

	 	a.	 Arbitrator. To the extent that the Parties cannot agree on a single arbitrator, the
arbitration shall be conducted by a panel of three arbitrators (the “Panel”). Each Party to the dispute shall have the right to appoint one (1) member of the Panel, with the third member to be mutually agreed by
the two Panel members appointed by the Parties or appointed in accordance with the rules of the American Arbitration Association (if there are only two parties to the dispute). All panel members shall be selected from a pool of independent
arbitrators. Each Party shall make its appointment within twenty (20) days of receipt of the ADR request and the third panel member shall be selected by the two panel members within ten (10) days of the selection of the first two panel
members (if applicable). 

  

	 	b.	 Proceedings. The Parties will cooperate in good faith in the voluntary, prompt and
informal exchange of non-privileged documents and other information relevant to the ADR. The Parties and the Panel will make every effort to conclude the information exchange process within ninety
(90) days after the Panel is selected. Within seven (7) days after selection of the Panel, each Party may serve on any other Party up to ten (10) interrogatories (or a number otherwise set by the arbitrators), without subparts, for
the purpose of identification of documents and witnesses. These interrogatories will be answered within seven (7) days. 

At any time after the selection of the Panel, but no later than thirty (30) days before the ADR hearing, each Party may
take up to three (3) depositions (or a number otherwise set by the arbitrators) of an opposing Party as a matter of right. The Parties will attempt to agree to time, location and duration of the deposition, and if the Parties do not agree these
will be determined by the Panel. 
 Any Party may conduct depositions of its own witnesses which may be introduced as
evidence at the ADR hearing if the other Party was given fair opportunity to attend the deposition and cross-examine. 

  
 Page 30 

 Upon the request of any Party, the Panel will conduct a conference for the
purpose of determining additional information to be exchanged. Parties may request additional depositions, interrogatories or document Production. If the Panel determines that the requesting Party has a reasonable need for the requested information
and that the request is not overly burdensome on the opposing Party, the Panel shall order the additional information exchange. 

As they become aware of new documents or information, including experts who may be called upon to testify, all Parties remain
under a continuing obligation to provide documents upon which they rely, to supplement their responses, and to honor any informal agreements or understandings between the Parties regarding documents or information to be exchanged. Documents which
have not been previously exchanged will not be considered by the Panel at the hearing, unless agreed by the Parties. 

The Parties will promptly notify the Panel when an unresolved dispute exists regarding discovery issues. The Panel will discuss
the matter with the Parties to determine the nature of the dispute and will attempt to resolve that dispute. If the Panel does not resolve the dispute, the Panel will arrange a conference concerning the dispute before the Panel by telephone, or in

multiplying the Net Sales (as determined above) of the Combination Product, during the applicable royalty reporting period, by the fraction, A/(A+B), where A is the average sale price of the
Product when sold separately in finished form and B is the average sale price of the other active ingredient(s) included in the Product when sold separately in finished form, in each case during the applicable royalty reporting period or, if sales
of both the Product and the other active ingredient(s) did not occur in such period, then in the most recent royalty reporting period in which sales of both occurred. In the event that such average sale price cannot be determined for both the
Product and all other active ingredient(s) included in such Combination Product, Net Sales for the purposes of determining royalty payments shall be calculated by multiplying the Net Sales of the Combination Product by the fraction of C/(C+D) where
C is the fair market value of the Product and D is the fair market value of all other active ingredient(s) included in the Combination Product. In such event, the Parties shall negotiate in good faith to determine of the respective fair market
values of the Product and all other active ingredient(s) included in the Combination Product based on the relative value contributed by each component.

 2. GOVERNANCE 

  
 - 22 - 

 2.1 Joint Research Committee. 

(a) Establishment of JRC. Within [***] ([***]) [***] after the Effective Date, the Parties will establish a joint research
committee with the roles set forth in Section 2.1(c) (the “Joint Research Committee” or “JRC”). Each Party will initially appoint three (3) representatives to the JRC. The JRC may change its size
from time to time by mutual consent of its members, provided that the JRC will consist at all times of an equal number of representatives of each of Ambrx and BeiGene. The JRC membership and procedures are further described in this
Section 2.1. Each Party may at any time appoint different JRC representatives by written notice to the other Party. 

(b) Membership of JRC. Each of Ambrx and BeiGene will designate representatives with appropriate expertise to serve as members
of the JRC. Each of Ambrx and BeiGene will select from their representatives a co-chairperson for the JRC, and each Party may change its designated co-chairperson from
time to time upon written notice to the other Party. The co-chairpersons of the JRC, with assistance and guidance from the Alliance Managers, will be responsible for calling meetings and preparing and
circulating an agenda in advance of each meeting, provided that the co-chairpersons will call a meeting of the JRC promptly upon the reasonable written request of either
co-chairperson to convene such a meeting. 
 (c) Role of JRC. The JRC will be
responsible for (i) the overall management of the Research Programs, and for approving amendments to the Research Plan (as set forth in Section 3.4), (ii) the monitoring, reviewing and assessing the progress of the Research
Programs, (iii) setting, and monitoring the spending against, the Budget for Research Programs costs, (iv) evaluating and determining whether a Compound delivered by Ambrx has met the PCC Criteria for a Research Program, and
(v) nominating the Evaluation Compounds, discussing and evaluating the performance of the Evaluation Compounds and designating the Initial Compound, discussing and evaluating the Initial Research Program, a New Program or Replacement Program
and approving and adopting appropriate amendments of the Research Plan for such New Program or Replacement Program. As needed, the JRC shall establish subcommittees and working groups that will report to the JRC to further the objectives of the
Research Programs. 
 (d) JRC Meetings. The JRC will hold meetings at such times and places as the co-chairpersons may determine. The JRC will meet at least once every Calendar Quarter during the Research Term. The meetings of the JRC need not be in person and may be by telephone or any other method determined by
the JRC. Each Party will bear its own costs associated with attending such meetings. The Alliance Managers will work with the chairpersons to prepare and circulate agendas and to ensure the preparation of minutes. 

(e) Decisions. Decisions of the JRC shall be by consensus, provided that if the JRC is unable to reach consensus with respect to
any such decision, Ambrx or BeiGene shall have the final decision-making authority regarding the matters set forth in Exhibit C; provided further that either Party may not use its final decision-making authority to (i) require the
other Party to violate any Applicable Law or breach any agreement it may have with any Third Party, 

  
 - 23 - 

 
(ii) amend the terms and conditions of this Agreement, (iii) make any changes in the number of BeiGene-funded FTEs except in accordance with Section 3.5(b), (iv) require the
other Party to conduct any activities outside the scope of the Research Plan, or (v) require Ambrx to agree to a New Program or Replacement Program which is subject to Pre-Existing Restrictions. Subject
to the foregoing, if the JRC is unable to reach consensus with respect to any decision on which neither BeiGene nor Ambrx has the final decision-making authority in accordance with Exhibit C, the Parties agree to follow the expedited
arbitration procedures set forth in Section 14.3 to resolve the matter. 
 (f) Discontinuation of JRC. The JRC
shall continue to exist until the first to occur of (i) the Parties mutually agreeing to disband the JRC or (ii) at any time after the expiration of the Research Term for the last Research Program, upon thirty (30) days written notice
by either Party. On a Research Program-by-Research Program basis, from and after the Pre-Clinical Candidate Attainment Date for
such Research Program, the JRC shall not have any further decision making authority with respect to such Research Program and all subsequent decisions regarding the further Research, Development, manufacture and Commercialization of the applicable
Compounds and associated Products for such Research Program shall be at BeiGene’s sole discretion, subject to the terms of this Agreement. From and after the discontinuance of the JRC pursuant to Section 2.1(f)(i) or
Section 2.1(f)(ii), the JRC shall have no further roles or responsibilities under this Agreement. Any subcommittees and working groups established by the JRC in connection with the Research Program will dissolve at the expiration of the
Research Term for the last Research Program. 
 2.2 Limitations on Authority of the JRC. The JRC will have solely the roles
and responsibilities assigned to it in this Article 2. The JRC will have no authority to amend, modify or waive compliance with this Agreement. For the avoidance of doubt, the JRC will have no authority to amend, modify or limit the
final decision-making authority of Ambrx or BeiGene with respect to the matters as set forth in Exhibit C of this Agreement. The JRC shall not have the authority to alter, or waive compliance by a Party with, a Party’s obligations under
this Agreement. 
 2.3 Alliance Managers. Each of the Parties will appoint one representative who possesses a general
understanding of research and development issues to act as its alliance manager (each, an “Alliance Manager”). The role of the Alliance Manager is to act as a primary point of contact between the Parties to assure a successful
relationship between the Parties. The Alliance Managers will attend all meetings of the JRC and support the co-chairpersons of the JRC in the discharge of their responsibilities. An Alliance Manager may bring
any matter to the attention of the JRC if such Alliance Manager reasonably believes that such matter warrants such attention. Each Party may change its designated Alliance Manager from time to time upon written notice to the other Party. Any
Alliance Manager may designate a substitute to temporarily perform the functions of such Alliance Manager upon written notice to the other Party’s Alliance Manager. Each Alliance Manager will be charged with creating and maintaining a
collaborative work environment within the JRC. Each Alliance Manager also will: 

  
 - 24 - 

 (a) provide a single point of communication both internally within the Parties’
respective organizations and between the Parties, including during such time as the JRC is no longer constituted; 
 (b) plan and
coordinate any cooperative efforts under this Agreement, if any, and internal and external communications; and 
 (c) take
responsibility for ensuring that JRC activities, such as the conduct of required JRC meetings and preparation and circulation of agendas and minutes therefor, occur as set forth in this Agreement and that relevant action items, if any, resulting
from such meetings are appropriately carried out or otherwise addressed. 
 3. RESEARCH PROGRAM 

3.1 Research Programs. 

(a) Subject to and in accordance with the terms of this Agreement, during the Research Term, the Parties will collaborate in
Researching Compounds pursuant to the Research Programs with the goal of identifying Compounds that meet PCC Criteria for BeiGene to advance into human Clinical Trials and ultimately Commercializing as Products. The Research Programs will also
include activities directed toward the Research of Compounds that are backups or alternatives to lead Compounds. Each Party will conduct its activities under each Research Program in accordance with the Research Plan. On a Research Program-by-Research Program basis, after the Pre-Clinical Candidate Attainment Date for such Research Program, BeiGene shall have the
right to further Research, Develop, manufacture and Commercialize all Compounds and associated Products from such Research Program as a Licensed Program. 

(b) The Parties will collaborate with respect to the Initial Research Program, which can be replaced up to [***] ([***]) times in
accordance with Section 3.1(f), and up to [***] ([***]) New Programs, which shall be selected in accordance with this Section 3.1. 

(c) As of the Effective Date, the Parties have mutually agreed to collaborate on the Initial Research Program. At the first JRC
meeting, the Parties shall select [***] Evaluation Compounds, which will be evaluated during the Evaluation Exclusivity Period. On or prior to the end of the Evaluation Exclusivity Period, the JRC shall select and designate [***] of these [***]
([***]) Evaluation Compounds that meets the PCC Criteria as the Initial Compound. If at the end of the Evaluation Exclusivity Period, neither Evaluation Compound meets the PCC criteria, unless the Parties agree through the JRC otherwise, then the
Research Program respect to each Evaluation Compound shall terminate and the JRC shall propose a Replacement Program in accordance with and subject to the procedure set forth in Section 3.1(f). 

(d) Promptly after the first JRC meeting, the Parties will amend and update Exhibit D to include the required information for
each Research Program, including under the “Description of the Research Program” therein, an outline the activities and work to be conducted by or on behalf of the Parties under the applicable Research Program and resources

  
 - 25 - 

 
allocated to such Research Program. The Research Plan for each New Program, the Initial Program and Replacement Program will include at least the information set forth on Exhibit D. For
clarity, BeiGene, in its sole discretion, is entitled to add, replace, update or modify the list of BeiGene Agents in a given Research Program from time to time upon written notice to Ambrx. After such written notice to Ambrx, the JRC will amend or
revise the applicable Research Plan to reflect such addition, replacement, update or modification of the list of BeiGene Agents. 

(e) During the Research Term, BeiGene may, in its sole discretion, designate [***] New Programs in accordance with and subject to the
procedure described in Section 3.1(g) and after paying the fee for New Programs in accordance with Section 8.2(a), provided that the aggregate number of New Programs may not exceed [***] ([***]) (the “Program
Cap”). For the avoidance of doubt, the Initial Research Program (including the Replacement Program thereof) shall not be considered a New Program or count towards the Program Cap. 

(f) At any time prior to [***], BeiGene may, in its sole discretion, replace the Initial Research Program with a Replacement Program in
accordance with and subject to the procedure described in Section 3.1(g) and after paying the replacement fee in accordance with Section 8.2(b). Prior to [***], BeiGene may, in its sole discretion, replace such Replacement
Program with another Replacement Program in accordance with and subject to the procedure described in Section 3.1(g) and after paying the replacement fee in accordance with Section 8.2(b). 

(g) In the case where BeiGene desires to replace the Initial Research Program (or a Replacement Program thereof) with a proposed
Replacement Program or add a New Program, BeiGene shall provide written notice to the Gatekeeper, including (i) a statement as to whether BeiGene is selecting a Replacement Program or a New Program, (ii) the identity of the Initial
Research Program (or a Replacement Program thereof) that would be terminated and replaced (if applicable), and (iii) a brief written description of the proposed New Program or Replacement Program, which notice shall include (A) the Entrez
Gene ID, HUGO or official symbol and common synonyms (if available) for the proposed Target for such program, and (B) the proposed type of Compound, including the Component A therefor and Component B therefor (e.g., [***], etc.) (if and to the
extent applicable) for such program (the “Nomination Notice”). Within [***] ([***]) [***] after the date of a Nomination Notice, the Gatekeeper will provide written notice to Ambrx that BeiGene has issued a Nomination Notice (each a
“Gatekeeper Nomination Notice”). Within [***] ([***]) [***] after the date of the Gatekeeper Nomination Notice, Ambrx will provide to the Gatekeeper a written list of all then-existing
Pre-Existing Restrictions. Within [***] ([***]) [***] after the date of Ambrx’s notice, the Gatekeeper shall verify whether the proposed New Program or Replacement Program is or is not on the list of Pre-Existing Restrictions and notify each of the Parties in writing whether such proposed New Program or Replacement Program is or is not available (each a “Gatekeeper Availability Notice”). If the
Gatekeeper Availability Notice indicates that such proposed New Program or Replacement Program is not available, the details of the proposed New Program or Replacement Program (i.e., the identity of the proposed Target and type of Compound) shall be
redacted from the Gatekeeper Availability Notice to Ambrx and the Gatekeeper Availability Notice will 

  
 - 26 - 

 
indicate only that the proposed New Program or Replacement Program is subject to Pre-Existing Restrictions, and thereafter, BeiGene may issue further
Nomination Notices during the remainder of the Research Term. If the Gatekeeper Availability Notice indicates that such proposed New Program or Replacement Program is available, then (1) such proposed New Program or Replacement Program will be
deemed be accepted for purposes of this Agreement, (2) the Parties will update Exhibit D to include a description of the agreed upon New Program or Replacement Program, (3) the Parties will amend the Research Plan to include such
New Program or Replacement Program in accordance with Section 3.4(b), (4) the Parties will have all rights and obligations hereunder in connection with such New Program or Research Program as a “Research Program”, including
with respect to the associated Compounds (including the exclusivity in accordance with Section 7.7) as of the date of such Gatekeeper Availability Notice, (5) BeiGene will pay the applicable fees set forth in
Section 8.2, if any, and (6) if the Initial Research Program (or the Replacement Program thereof) is replaced with a Replacement Program, then all of the Parties’ rights and obligations hereunder (including the exclusivity in
accordance with Section 7.7) with respect to such replaced Research Program will automatically terminate and such replaced Research Program will be considered terminated as if such Research Program were terminated in accordance with
Section 11.2 and all Compounds in such Research Program shall become “Reversion Products”. BeiGene’s right to nominate additional proposed New Programs or Replacement Programs shall expire upon the expiration or
termination of the Research Term; provided that (a) BeiGene shall have the right to designate up to [***] ([***]) New Programs, in the aggregate and (b) only the Initial Research Program can be replaced and it can be replaced up to [***]
([***]) times and in accordance with Section 3.1(f) only. 
 (h) During the Research Term and with respect to each
Research Program, each Party will use Commercially Reasonable Efforts to perform and complete (itself or through its Affiliates or by permitted subcontracting) its respective obligations under the Research Plan, and will cooperate with and provide
reasonable support to the other Party in such other Party’s performance of its responsibilities under the Research Plan. Without limiting the foregoing, for each Research Program, Ambrx shall use Commercially Reasonable Efforts to Research
Compounds and identify at least [***] ([***]) [***] that meets the PCC Criteria set out in the Research Plan for such Research Program. For clarity, in no event shall “Commercially Reasonable Efforts” require Ambrx to spend money or
allocate more staff that is more than the amount of Budget or the number of FTEs set forth in the applicable Research Plan. 
 (i)
The Research Programs will be conducted by each Party in good scientific manner, and in compliance in all material respects with all applicable Good Laboratory Practices and Applicable Laws, to attempt to achieve efficiently and expeditiously the
objectives of the Research Programs. Each Party will comply in all material respects with the requirements of all Applicable Laws in the performance of its activities under this Agreement. Each Party shall use reasonable efforts to ensure that its
Affiliates and Third Party contractors (as applicable) perform any activities under the Research Programs in good scientific manner and in compliance in all material respects with the requirements of Applicable Law. 

  
 - 27 - 

 (j) Each Party will maintain laboratories, offices and all other facilities at its
own expense and risk necessary to carry out its responsibilities under the Research Programs pursuant to the Research Plan. Each Party agrees to make its employees reasonably available at their respective places of employment to consult with the
other Party on issues arising during the performance of the Research Programs. BeiGene and Ambrx will cooperate with each other in carrying out the Research Programs. 

3.2 Compounds; Exchange of Information. 

(a) During the Research Term, BeiGene, in its sole discretion, may select and provide to Ambrx the sequences for biologics, such as
[***], in the cases when the sequences are not available at Ambrx, to be used for Compounds to be made and tested in the conduct of the Research Programs. The position of non-natural amino acid substitution
for Compounds (i.e., the Bare Compound sequence) to be made and tested in the conduct of the Research Programs shall be selected by the JRC, with [***] having final decision-making authority in the case where consensus is not reached by the JRC with
respect to such selection. Compounds to be made and tested in the conduct of the Research Programs may be comprised of but not limited to any combination of components, including [***] as selected by the JRC, with [***] having final decision-making
authority in the case where consensus is not reached by the JRC with respect to such selection. 
 (b) During the Research Term,
Ambrx will maintain and promptly share with BeiGene a list of all identified Compounds for each Research Program, and all associated Know-How for such Compounds. 

(c) In accordance with the Research Plan and under the direction of the JRC, Ambrx will be responsible for delivering to BeiGene
quantities of candidate Compounds (in Bare Compound and conjugated form, in accordance with the Research Plan) sufficient for non-GLP pharmacology and preliminary toxicology evaluations by BeiGene, and BeiGene
shall conduct non-GLP pharmacology and preliminary toxicology evaluations and timely share the results of such evaluations with Ambrx through the JRC. Upon request by BeiGene through the JRC, Ambrx will
prepare and transfer to BeiGene stable expression cell lines (and research cell banks thereof) for production of Bare Compounds for such purpose. 

(d) Ambrx will be responsible for delivering stable expression clones for Bare Compounds to BeiGene and for the master cell bank
creation. Upon BeiGene’s request, Ambrx will transfer such master cell banks to BeiGene or its designee. 
 3.3 Research
Term. 
 (a) The Parties will perform Research activities under the Research Programs only during the Initial Research Term,
unless no later than [***] ([***]) [***] prior to the expiration of such Initial Research Term, BeiGene requests in writing an extension of such Initial Research Term for any then-ongoing Research Program for which one or both Parties is pursuing

  
 - 28 - 

 
activities under the Research Plan, which written request will specify the Research Program(s) under which BeiGene desires to extend activities and the time period for which BeiGene desires to
extend the performance of such activities (the “Research Term Extension”), provided that such time period may not exceed a period of [***] ([***]) [***] following the Initial Research Term. If BeiGene so requests during such [***]
([***]) [***] period, then the Parties will continue to perform Research and funding activities for such specified Research Programs under the Research Plan during the Research Term Extension. 

(b) Notwithstanding the provisions of Section 3.3, on a Research Program-by-Research Program basis, BeiGene shall have the right, in its discretion, to discontinue a given Research Program at any time prior to the scheduled end of the applicable Research Term by providing
no less than [***] ([***]) [***] prior written notice of such discontinuance to Ambrx (which notice shall identify the Research Program being discontinued and that the applicable Research Program is being discontinued pursuant to this
Section 3.3(b)). Upon delivery of such Research Program discontinuance notice by BeiGene to Ambrx, the Research Term for the applicable Research Program shall automatically end on the date set forth in the discontinuance notice (but in
any event no sooner than [***] ([***]) [***] following the delivery of such discontinuance notice). For the avoidance of doubt, such discontinuance in accordance with this Section 3.3(b) shall be considered a termination of the
applicable Research Program pursuant to Section 11.2. 
 3.4 Research Plan. 

(a) During the Research Term, the Research Programs will be carried out in accordance with a written research plan (the
“Research Plan”). The Research Plan will be mutually agreed to by the Parties and attached to the meeting minutes of the JRC once mutually agreed. The purpose of the Research Plan is to detail the responsibilities and activities of
Ambrx and BeiGene in carrying out the Research Programs. For each Research Program, the Research Plan will include a description of the applicable Compounds and Target(s) for such Research Program, the PCC Criteria for
Pre-Clinical Candidates for such Research Program, a description of the specific activities to be performed by Ambrx and BeiGene in support of such Research Program, a description of the Ambrx Technology
Platforms and BeiGene Technology Platforms and the initial BeiGene Agent, if any, to be applied or used for such Research Program, the allocation and number of Ambrx FTEs to perform such activities, projected timelines for completion of such
activities, and, as applicable, provisions for the supply of Compounds by Ambrx to BeiGene for testing. The Research Plan will also include a budget for the BeiGene-funded Ambrx FTEs (based on the number of BeiGene-funded Ambrx FTEs and the FTE
Rate) and any Third Party Costs (the “Budget”), with such Budget to be updated in advance for periodic review by the JRC, subject to this Section 3.4 and Section 3.5. In the event of any inconsistency between
a Research Plan and this Agreement, the terms of this Agreement shall control. 
 (b) Within [***] ([***]) [***] after the date that
a New Program or Replacement Program is added as a Research Program in accordance with Section 3.1(d) (or 

  
 - 29 - 

 
such longer period of time as reasonably determined by the JRC), the Parties shall jointly prepare for the JRC’s approval proposed amendments to the Research Plan for each New Program or
Replacement Program. Once approved by the JRC, such amendments to the Research Plan shall become effective for such new Research Program. 

(c) During the Research Term, the Research Plan shall be reviewed, updated and amended at least on a [***] basis, as the JRC
determines, including for purposes of continuing with the Research Program in accordance with Section 3.6(g), provided that if the JRC cannot reach consensus, the matter shall be considered an Expedited Dispute and determined in
accordance with Section 14.3. Such amended Research Plan will cover the next Calendar Year (and additional periods as reasonably determined by the JRC) or the remainder of the Research Term (if the remainder of the Research Term is less than
a Calendar Year). Such updated and amended Research Plan will reflect any changes (including any new or replaced BeiGene Agents (if any)), re-prioritization of studies within, reallocation of resources with
respect to, or additions to, respectively, the then-current Research Plan. Once approved by the JRC, the amended annual Research Plan will become effective for the applicable period on the date approved by the JRC (or such other date as the JRC will
specify). Any JRC-approved amended Research Plan will supersede, respectively, the previous Research Plan for the applicable period. 

(d) During the Research Term, each Party shall provide prompt written notice to the JRC if at any time it believes that it may or is
actually running more than [***] ([***]) [***] ahead or behind the timeline set forth in any then-current Research Plan. 
 3.5 Research
Staffing and Funding. 
 (a) Subject to Section 3.5(b), upon the commencement of activities under the Research Plan
for the Initial Research Program, BeiGene will pay Ambrx the FTE Costs for FTE hours actually worked in support of the Research Programs, and Ambrx shall provide the number of Ambrx FTEs per Research Year during the Research Term to perform
activities in support of the Research Programs, in each case, in accordance with the then-current Research Plan, the Budget and this Agreement, including this Section 3.5. Throughout the Research Term, (i) Ambrx shall assign no less
than the number of qualified scientist FTEs in accordance with the Research Plan to perform the work set forth in the Research Plan, with the mixture of skills and levels of such FTEs to be appropriate to accomplish the scientific objectives of the
Research Program and (ii) BeiGene shall pay Ambrx the FTE Costs for the FTE hours actually worked by such FTEs in support of the Research Program; provided that BeiGene shall be obligated to pay Ambrx the FTE Costs for a minimum of [***]
([***]) Ambrx FTEs per Calendar Year and up to a maximum of [***] ([***]) Ambrx FTEs per Calendar Year, regardless of whether less than [***] ([***]) FTEs or more than [***] ([***]) FTEs perform actual work in support of the Research Program for the
applicable Calendar Year. For clarity, the FTE Rate shall apply only to employees of Ambrx. All other costs and expenses incurred by Ambrx in connection with the performance of the Research Program, including amounts paid to subcontractors, shall be
in accordance with the Budget and paid in accordance with Section 3.5(c). No later than [***] 

  
 - 30 - 

 
([***]) [***] following the end of each Calendar Quarter during the Research Term, Ambrx will provide BeiGene with a reasonably detailed invoice, which shall include a report of the number of
FTEs assigned to each Research Program with a description of the activities conducted by each FTE under the Research Plan during such Calendar Quarter and the FTE Cost per FTE. BeiGene’s obligation to fund FTE’s shall not include [***]. No
later than [***] ([***]) [***] after receipt of an invoice from Ambrx, BeiGene will make payment of undisputed FTE Costs for such Calendar Quarter. 

(b) If the activities contemplated by the Research Plan at any time during the Research Term do not justify the number of Ambrx FTEs
allocated to the Research Program under the Research Plan, the Parties shall work in good faith through the JRC to mutually agree on amendments to the Research Plan in accordance with Section 3.4(c), including to adjust the number of
BeiGene-funded Ambrx FTEs. Except when a Compound becomes a Pre-Clinical Candidate for a given Research Program in accordance with Section 3.6(e) or as the Parties otherwise agree in writing, any
changes requested by BeiGene to the number of BeiGene-funded Ambrx FTEs (whether a decrease or an increase) during the Research Term shall require that BeiGene provide Ambrx with [***] ([***]) [***] prior written notice before such change in the
number of BeiGene-funded Ambrx FTEs becomes effective, provided that (x) any increase in the number of BeiGene-funded Ambrx FTEs within the permitted range shall be subject to the availability of such additional Ambrx FTEs (provided that Ambrx
shall use commercially reasonable efforts to hire and otherwise make available such additional FTEs), and (y) in no event will BeiGene have the right to increase the number of Ambrx FTEs to exceed [***] ([***]) FTEs in total or decrease the
number of Ambrx FTEs below [***] ([***]) FTEs in total at any time during the Research Term without Ambrx’s prior written consent. Any changes to the Research Plan and assignment and allocation of activities to be performed by the
BeiGene-funded Ambrx FTEs shall require the approval of the JRC, provided that if the JRC is unable to reach consensus, the matter shall be determined in accordance with Exhibit C. In exercising such final decision-making authority, neither
Party shall have the right to amend the terms and conditions of this Agreement. 
 (c) Ambrx will bear its own costs, including costs
related to routine laboratory supplies and other applicable overhead costs, in performing its obligations under the Research Program, provided that, subject to the terms and conditions of this Agreement (including this
Section 3.5(c)), BeiGene will pay FTE Costs to Ambrx for the BeiGene-funded Ambrx FTEs in accordance with Section 3.5(a) and reimburse Third Party Costs incurred by Ambrx at cost without
mark-up in categories and amounts previously agreed to by the Parties through the JRC and in accordance with the Research Plan and Budget. Ambrx shall invoice BeiGene for the Third Party Costs within [***]
([***]) [***] after its receipt of the invoices from the Third Parties, with supporting documentation. BeiGene shall pay such invoice within [***] ([***]) [***] after receipt of such invoice. Ambrx shall be solely responsible for managing the
performance of its subcontractors. Ambrx agrees to provide BeiGene with full transparency into all Third Party Costs with respect to the Research Program. In addition, Ambrx will maintain records relating to all Third Party Costs for the performance
of the Research Program. BeiGene 

  
 - 31 - 

 
shall have the right to audit Ambrx’s records in connection therewith in accordance with Section 8.13, mutatis mutandis. 

(d) Ambrx shall use the portion of the funding it receives from BeiGene for FTE Costs solely to carry out its work under the Research
Programs and the terms and conditions of this Agreement and for no other purposes. 
 3.6 Delivery of Research Data Package and
Compounds. 
 (a) For each Research Program, at the earlier of (i) the time set forth in the Research Plan or (ii) no
later than [***] ([***]) [***] prior to the expiration of the Research Term for such Research Program, Ambrx will prepare and deliver to BeiGene the applicable Research Data Package for such Research Program. Without limiting the provisions of this
Section 3.6(a), BeiGene will have the right at any time, in its sole discretion, to designate in writing [***] Compounds under a given Research Program to be Pre-Clinical Candidate(s) from such

 8.3 Development Milestone Payments 

(a) On a Program-by-Program basis, BeiGene shall pay to
Ambrx the one-time milestone payments set forth in Table 1 (each a “Development Milestone Payment”) for each Program after the first achievement of the specified milestone event (each a
“Development Milestone Event”) by BeiGene, its Sublicensees or their Affiliates for a given Program. Thus, the Development Milestone Payments set forth in Table 2 are payable only once for per Program, upon the first achievement of
the applicable Development Milestone Event, and no Development Milestone Payments under this Section 8.3(a) will be payable for any subsequent achievement of any Development Milestone Event under such Program (and accordingly the set of
Development Milestone Payments (2)-(12) in Table 2 shall be payable one-time only for a particular Program). BeiGene shall provide written notice to Ambrx within [***] ([***]) [***] after the first achievement
of the specified Development Milestone Event by BeiGene or its Affiliates or its Sublicensees was achieved, together with the corresponding Development Milestone Payment.

developmental milestone payments for a given Program 
 8.4 Sales-Based Milestone Payments. 

(a) BeiGene will make the one-time payments set forth in Table 3 below (the “Sales
Milestone Payments”) to Ambrx when the aggregate annual Net Sales for all Product(s) for a Program in the Territory in a given Calendar Year by BeiGene, its Affiliates and Sublicensees first reach or exceed the Net Sales threshold amounts
set forth below (each a “Sales Milestone Event”).

 For the avoidance of doubt, in no event shall BeiGene be required to pay to Ambrx in excess of [***] in the
aggregate in Sales Milestone Payments for a given Program. The above Sales Milestone Payments are payable only once for all Products for a Program, once the total Net Sales of all the Products for such Program in a Calendar Year reaches the
indicated Sales Milestone Event, notwithstanding the number of times one or more Products for such Program may achieve any such Sales Milestone Event. BeiGene will notify Ambrx within [***] ([***]) [***] after the Calendar Month in which the
applicable Sales Milestone Event was achieved, together with the payment for the corresponding Sales Milestone Payment. 
 8.5 Royalty
Payments to Ambrx.
 (a) General. Subject to the other provisions of this Article 8 and other provisions of
this Agreement, in consideration of the license granted by Ambrx to BeiGene pursuant to Section 7.1, on a Product-by-Product and country-by-country basis, BeiGene shall pay to Ambrx royalties based on the Net Sales of each Product during the applicable Royalty

  
 - 46 - 

 
Term for such Product. The royalty payable with respect to each particular Product shall be based on the level of annual Net Sales of such Product in the Territory in a given Calendar Year period
by BeiGene, its Affiliates and Sublicensees, with the royalty rate tiered based upon the level of such worldwide Net Sales in such Calendar Year period. Royalties shall be calculated by multiplying the applicable royalty rates by the corresponding
amount of the portion of Net Sales of the applicable Product within each of the Net Sales tiers during such Calendar Year as set forth below. 

(b) Base Royalty Rate. BeiGene will pay to Ambrx a royalty on Net Sales of Products, on a Product-by-Product and country-by-country basis, by BeiGene, its Affiliates and Sublicensees in the Territory based on the Net
Sales tiers and royalty rates as set forth in the table below (the “Base Royalty Rate”) (subject to any offsets or reductions set forth below in this Section 8.5). 

 

			
	 Annual Net Sales for each Product
	  	Base Royalty Rate
	Portion of worldwide Net Sales for each Product less than or equal to [***]	  	[***]
	Portion of worldwide Net Sales for each Product greater than [***] and less than or equal to [***]	  	[***]
	Portion of worldwide Net Sales for each Product greater than $2 billion	  	[***]

 For clarity, the Net Sales thresholds in the table above shall be determined on a Product-by-Product basis. By way of example, if the worldwide Net Sales of a Product in the Territory in a particular Calendar Year are [***], the amount of royalties payable
hereunder shall be calculated as follows (subject to any applicable reductions under this Section 8.5): ([***]. 

(c) Royalty Rate Reduction after Patent Expiration. Notwithstanding the foregoing, if during the Royalty Term for a given
Product in a particular country, there is no Valid Claim of any Royalty Patent that would be infringed by the sale of such Product in such country absent a license with respect to such Royalty Patent under this Agreement, then the Base Royalty Rate
(subject to any offsets or reductions set forth below in this Section 8.5) as applied to the sale of such Product in each such country shall be reduced by [***] ([***]) (i.e., the Base Royalty Rate shall be [***] the rates set forth in
the table above). 
 (d) Third Party Royalty Payments. 

(i) Subject to the remainder of this Section 8.5(d), Ambrx shall bear all Third Party license payments, milestones,
royalties and other payments owed with respect to all Compounds or Products involving intellectual property (including Patents) that is licensed or 

  
 - 47 - 

 
otherwise acquired by Ambrx as of the Effective Date (including any payment obligations of Ambrx under the Existing License Agreements). 

(ii) Subject to Section 9.5, if BeiGene in its good faith judgment, believes it is necessary or desirable to obtain a
license from any Third Party under any Necessary Third Party Patent (or obtain a sublicense under Section 7.4 with respect to a Future Third Party Patent that is a Necessary Third Party Patent) in order to Research, Develop, manufacture
or Commercialize any Compound or Product in the Field in the Territory, BeiGene’s royalty obligations set forth above shall be reduced by [***] ([***]) of the amount of the royalty payments actually made by BeiGene to such Third Party (or to
Ambrx with respect to a Future Third Party Patent that is a Necessary Third Party Patent) on account of such license, provided that the royalties paid shall not be reduced in any such event below [***] ([***]) of the amount that would otherwise be
due pursuant to Section 8.5(b) with respect to any Calendar Quarter; provided, further, that any deductions in excess of [***] ([***]) will be carried forward to reduce subsequent amounts until all such amounts are fully deducted.
“Necessary Third Party Patent” means a Third Party’s Patent that Covers such Compound or Product in the Field in the Territory. 

(e) Biosimilar Competition. On a
Product-by-Product and country-by-country basis, the royalties owed with respect to a
Product in a country in the Territory pursuant to Section 8.5(b) shall be reduced (i) by [***] ([***]), following a launch of a Biosimilar Product, if the unit sales of all Biosimilar Products in such country exceed [***] ([***]) of
the sum of unit sales of the Product plus unit sales of all Biosimilar Products in such country, (ii) by [***] ([***]) following a launch of a Biosimilar Product, if the unit sales of all Biosimilar Products in such country exceed [***] ([***])
of the sum of unit sales of Product plus unit sales of all Biosimilar Products in such country, or (iii) by [***] ([***]) to become [***] ([***]) following a launch of Biosimilar Product, if the unit sales of all Biosimilar Products in such
country reaches [***] ([***]) of the sum of unit sales of Product plus unit sales of all Biosimilar Products in such country. For clarity, such reduction will not apply for any Calendar Quarter in which the market share of Biosimilar Products does
not meet any threshold in the preceding sentence. 
 (f) Compulsory Licenses. If a court or a governmental agency of competent
jurisdiction requires BeiGene, its Affiliate or its Sublicensee to grant a compulsory license to a Third Party with respect to Product in any country in the Territory with a royalty rate [***], then the royalty rate to be paid by BeiGene on Net
Sales in that country under Section 8.5(b) shall be [***]. 
 (g) Only One Royalty. Only one royalty will be due
with respect to the sale of the same unit of Product. Only one royalty will be due hereunder on the sale of a Product even if the Exploitation of such Product infringes more than one claim of the Ambrx Patents. 

8.6 Royalty Term. Royalties payable by BeiGene to Ambrx under Section 8.5 shall be paid on a Product-by-Product and country-by-country basis until the later of (i) ten (10) years

  
 - 48 - 

 
after First Commercial Sale of the applicable Product in such country, and (ii) expiration in such country of the last to expire Valid Claim of any Royalty Patent, where such Valid Claim
would be infringed absent a license by the sale of the applicable Product in the applicable country by an unauthorized party (the “Royalty Term”). 

8.7 Royalty Payments and Reports. Commencing upon the First Commercial Sale of a Product and continuing for the Royalty Term for
such Product, within [***] ([***]) [***] after each Calendar Quarter, BeiGene shall provide Ambrx with a statement, on a Product-by-Product and
country-by-country basis, of: (a) the amount of Net Sales of such Product in the Territory during the applicable Calendar Quarter and deductions applied in
calculating the Net Sales and (b) a calculation of the amount of royalty payment due in Dollars on such Net Sales for such Calendar Quarter, provided that such royalty report for the last Calendar Quarter for each Calendar Year shall in
addition provide a statement, on a Product-by-Product and country-by-country basis, of
the Net Sales amount of Product in the Territory countries during such Calendar Year, together with the corresponding royalty payment. All such reports will be treated as Confidential Information of BeiGene, subject to the confidentiality and non-use obligations set forth in Article 10. 
 8.8 Payment Method. All payments
due under this Agreement to Ambrx shall be made by bank wire transfer in immediately available funds to an account designated by Ambrx. All payments hereunder shall be made in Dollars. 

8.9 Taxes. Ambrx will pay any and all income taxes levied on account of all payments it receives under this Agreement. If laws
or regulations require that taxes be withheld with respect to any payments by BeiGene to Ambrx under this Agreement, BeiGene will (a) deduct such taxes from the payment made to Ambrx, (b) timely pay the taxes to the proper taxing
authority, and (c) send proof of payment to Ambrx and certify its receipt by the taxing authority within [***] ([***]) [***] following such payment. Each Party agrees to cooperate with the other Party in claiming refunds or exemptions from such
deductions or withholdings under any relevant agreement or treaty which is in effect. The Parties shall discuss applicable mechanisms for minimizing such taxes to the extent possible in compliance with Applicable Law. In addition, the Parties shall
cooperate in accordance with Applicable Law to minimize indirect taxes (such as value added tax, sales tax, consumption tax and other similar taxes) in connection with this Agreement. 

8.10 Royalty on Sublicensee Sales. BeiGene shall have the responsibility to account for and report sales of any Product by a
Sublicensee on the same basis as if such sales were Net Sales by BeiGene. 
 8.11 Foreign Exchange. Conversion of sales
recorded in local currencies to Dollars shall be performed in a manner consistent with BeiGene’s normal practices used to prepare its audited financial statements for internal and external reporting purposes. 

  
 - 49 - 

 8.12 Records. BeiGene shall keep, and shall cause its Affiliates and
Sublicensees to keep, complete, true and accurate books of accounts and records, including gross sales and any deductions thereto in connection with calculation of Net Sales, sufficient to determine and establish the amounts payable incurred under
this Agreement, and compliance with the other terms and conditions of this Agreement. Such books and records shall be kept reasonably accessible and shall be made available for inspection for a [***] ([***]) [***] period in accordance with
Section 8.13. 
 8.13 Inspection of BeiGene Records. Upon reasonable prior notice and written request, BeiGene
shall permit an independent nationally recognized certified public accounting firm (subject to obligations of confidentiality to BeiGene and Ambrx that are no less stringent than those set forth in Article 10 hereof), appointed by Ambrx
and reasonably acceptable to BeiGene, to inspect the audited financial records of BeiGene to the extent relating to payments to Ambrx; provided that such inspection shall not occur more often than [***] per Calendar Year. Any inspection
conducted under this Section 8.13 shall be at the expense of Ambrx, unless such inspection reveals any underpayment of the royalties due hereunder for the audited period by at least [***] ([***]), in which case the full costs of such
inspection for such period shall be borne by BeiGene. Any underpayment shall be paid by BeiGene to Ambrx within [***] ([***]) [***] with interest on the underpayment at the rate specified in Section 8.14 from the date such payment was
originally due, and any overpayment shall be credited against future amounts due by BeiGene to Ambrx. 
 8.14 Late Payments.
Any payments or portions thereof due hereunder that are not paid on the date such payments are due under this Agreement shall bear interest at a rate equal to the lesser of: (a) [***], at 12:01 a.m. on the first day of each Calendar Quarter in
which such payments are overdue or (b) [***]; in each case calculated on the number of days such payment is delinquent, compounded monthly. 

8.15 Right to Set-off. Either Party will have the right to deduct from amounts otherwise
payable hereunder any amounts payable to such Party (or its Affiliates) from the other Party (or its Affiliates) under this Agreement that have been determined in accordance with the dispute resolution procedures set forth in Article 14 or as
otherwise agreed to by the Parties. 
 9. PATENT PROSECUTION AND ENFORCEMENT 

9.1 Inventorship. 

(a) Inventorship of Inventions shall be determined in accordance with the patent laws of the United States for determining
inventorship; provided that in the event that determining inventorship in accordance with such laws would render any Patent that claims or covers such Invention invalid, inventorship shall be determined in accordance with the laws of the
jurisdiction where such Patent is filed.

(ii) Ambrx will have the first right (but not the obligation), at Ambrx’s sole discretion through counsel of its choosing that is
reasonably acceptable to BeiGene, to seek to abate any Competitive Infringement by enforcing any Ambrx Patents. If Ambrx does not take steps to abate such Competitive Infringement, within [***] ([***]) [***] after receipt of written notice of such
Competitive Infringement (or such shorter period of time as is required to comply 

  
 - 54 - 

 
with the provisions of Section 9.5(c) or the time periods set forth under any other Applicable Law in the United States or any other country in the Territory to not waive any
statutory rights), then Ambrx will provide BeiGene with notice of such decision and in any event, BeiGene will have the rights set forth in Section 9.5(e) with respect to enforcing any Ambrx Patents. Ambrx will pay all Patent Costs
incurred by Ambrx for such enforcement. 
 (b) Notwithstanding anything herein to the contrary, if either Party (or any of their
Related Parties) receives a copy of a Biosimilar Application naming a Compound or Product as a reference product or otherwise becomes aware that such a Biosimilar Application has been filed (such as in an instance described in
Section 351(1)(9)(C) of the PHSA), such Party will promptly notify the other Party. If either Party receives any equivalent or similar certification or notice in the United States or any other jurisdiction, either Party will, promptly, notify
and provide the other Party copies of such communication. 
 (i) BeiGene will designate pursuant to Section 351(l)(1)(B)(ii) of
the PHSA the outside counsel and in-house counsel who will receive confidential access to the Biosimilar Application. BeiGene will pay all Patent Costs for such enforcement under this

or Joint Collaboration IP) to list any Patents for which the enforcement rights in Section 9.5(c) are applicable, insofar as they meet the statutory requirements pursuant to Section 351(l)(1)(3)(A), Section 351(l)(5)(b)(i)(II),
or Section 351(l)(7) of the PHSA, to respond to any communications with respect to such lists from the filer of the Biosimilar Application, and to negotiate with the filer of the Biosimilar Application as to whether to utilize a different
mechanism for information exchange other than that specified in Section 351(l) of the PHSA. 
 (iii) BeiGene will have the
right (and after consulting with Ambrx with respect to any Ambrx Patents or Joint Collaboration IP) to identify Patents for which the enforcement rights in Section 9.5(c) are applicable, or respond to relevant communications under any
equivalent or similar listing to those described in Section 9.5(c) in any other jurisdiction outside of the United States. If required pursuant to Applicable Law, upon BeiGene’s request, Ambrx will assist in the preparation of such
list and make such response after consulting with BeiGene. 
 (iv) Ambrx will (1) within [***] ([***]) [***] after
BeiGene’s written request, provide to BeiGene all information, including a list of Patents Controlled by Ambrx Party and for which the enforcement rights in Section 9.5(c) are applicable, that is necessary or reasonably useful to
enable BeiGene to make any lists or communications with respect to such Patents that are described in Section 9.5(c), and (2) cooperate with the BeiGene’s reasonable requests in connection therewith to the extent required or
not prohibited by Applicable Law. BeiGene will consult with Ambrx prior to identifying any Patents controlled by Ambrx as contemplated by this Section 9.5(c)(iv). BeiGene will consider in good faith advice and

  
 - 55 - 

 
suggestions with respect thereto received from Ambrx, and will notify Ambrx of any such lists or communications promptly after they are made. 

(v) The Parties recognize that procedures other than those set forth above in this Section 9.5 may be applicable to
Biosimilar Applications that are not governed by the PHSA. As a result, in the event that the Parties acting in good faith mutually determine that certain provisions of Applicable Law in the United States or in any other country in the Territory are
applicable to actions taken by the Parties with respect to Biosimilar Applications under this Section 9.5(c) in such country, the Parties will comply with any such Applicable Law in such country (and any relevant and reasonable
procedures established by the) in exercising their rights and obligations with respect to Biosimilar Applications under this Section 9.5(c). 

(c) As between the Parties, the Party controlling the Prosecution and Maintenance of any Patent under Section 9.4 (i.e.,
BeiGene for the BeiGene Patents, Compound IP Patents and Joint Collaboration Patents and Ambrx for the Ambrx Patents), shall have the right (but not the obligation), at its sole discretion, to defend against a declaratory judgment action, inter
partes review, opposition proceeding, interference, or other action challenging any such Patent, other than with respect to (i) any counter claims or defenses in any enforcement action brought by the other Party pursuant to
Section 9.5(c) or (ii) any action by a Third Party in response to an enforcement action brought by the other Party, which in both cases ((i) and (ii)), will be controlled by such other Party. If Ambrx does not defend any Ambrx
Prosecuted Patent under this Section 9.5(d) within [***] ([***]) [***] (or such shorter period of time as is required to comply with the provisions of Section 9.5(c) or the time periods set forth under any other Applicable
Law in the United States or any other country in the Territory to not waive any statutory rights), or elects not to continue any such defense (in which case it will promptly provide notice thereof to BeiGene), then BeiGene will have the right (but
not the obligation), at its sole discretion, to defend any such Ambrx Prosecuted Patent. 
 (d) With respect to any infringement or
defensive action identified above in this Section 9.5 and subject to the terms of this Section 9: 
 (i) If
the controlling Party ceases to pursue or withdraws from such action, then it shall promptly notify the other Party in sufficient time to enable the other Party to meet any deadlines by which any action must be taken to preserve any rights in such
infringement or defensive action (including any such period of time as is required to comply with the provisions of Section 9.5(d)), then such other Party may substitute itself for the withdrawing Party and proceed under the terms and
conditions of this Section 9.5. 
 (ii) The non-controlling Party shall
cooperate with the Party controlling any such action (as may be reasonably requested by the controlling Party), including, at the controlling Party’s sole cost and expense, (a) providing access to relevant documents and other evidence,
(b) using reasonable efforts to make its and its Affiliates and licensees and Sublicensees and all of their respective employees, subcontractors, consultants, and agents available during reasonable business hours and for reasonable periods of
time, but only to the 

  
 - 56 - 

 
extent relevant to such action, and (c) if reasonably necessary, by being joined as a party, subject for this clause (c) to the controlling Party agreeing to pay those Patent Costs
incurred by such non-controlling Party in connection with such joinder. The Party controlling any such action shall keep the other Party reasonably updated with respect to any such action, including providing
copies of all materials documents received or filed in connection with any such action. 
 (e) With respect to any infringement or
defensive action identified above in this Section 9.5, the Party controlling such action shall have the right to settle or otherwise dispose of such action on such terms as such Party will determine in its sole discretion, including by
granting a license or sublicense to a Third Party under the rights granted to such Party in Section 7 in accordance with the sublicensing terms therein, as applicable. Notwithstanding the foregoing, no such settlement or other
disposition will (a) impose any monetary restriction or obligation on or admit fault of the other Party or (b) adversely affect the other Party’s rights under this Agreement to any such Patent then being enforced or defended, in each
case ((a) and (b)) without the prior written consent of the other Party, not to be unreasonably withheld. 
 (f) Unless otherwise
agreed by the Parties, all monies recovered upon the final judgment or settlement of any action described in this Section 9.5 shall be used first to reimburse the controlling Party for its Patent Costs arising from the action, with the
balance of any such recovery to be allocated as follows: (a) if Ambrx was the controlling Party, [***] ([***]) to Ambrx and [***] ([***]) to BeiGene, and (b) if BeiGene was the controlling Party, [***] ([***]) to BeiGene and [***] ([***])
to Ambrx. 
 (g) Upon request of BeiGene, Ambrx shall cooperate with BeiGene to: (i) file appropriate information with the FDA
in the U.S. listing any Ambrx Patents in the Purple Book; and (ii) with respect to other countries in the Territory, file appropriate information with the applicable Regulatory Authority listing any Ambrx Patents in the Patent listing source in
such country in the Territory that is equivalent to the Purple Book, if any. 
 (h) Notwithstanding anything in this
Section 9 to the contrary, each Party’s rights and obligations with respect to any Patent Controlled pursuant to an in-license under this Section 9 shall be subject to the Third
Party rights and obligations under any such applicable in-license. 
 (i) All information
exchanged between the Parties regarding the Prosecution and Maintenance, and enforcement and defense, of the Patents under this Section 9 shall be deemed Confidential Information of the disclosing Party. In addition, the Parties
acknowledge and agree that, with regard to such Prosecution and Maintenance, and enforcement and defense of the Patents under this Section 9, the interests of the Parties as collaborators and licensor and licensee are to obtain the
strongest patent protection possible, and as such, are aligned and are legal in nature. The Parties agree and acknowledge that they have not waived, and nothing in this Agreement constitutes a waiver of, any legal privilege concerning the Patents
under this Section 9, including privilege under the common interest doctrine and similar or related doctrines. Notwithstanding anything to the contrary contained herein, to the extent a Party has a

  
 - 57 - 

 
good faith believe that any information required to be disclosed by such Party to the other Party under this Section 9 is protected by attorney client privilege or any other
applicable legal privilege or immunity, such Party shall not be required to disclose such information and the Parties shall in good faith cooperate to agree upon a procedure (including entering into a specific common interest agreement, disclosing
such information on a “for counsel eyes only” basis or similar procedure) under which such information may be disclosed without waiving or breaching such privilege or immunity. 

10. CONFIDENTIALITY 

10.1 Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties,
each Party (the “Receiving Party”) agrees that, for the Term and for [***] ([***]) [***] 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 (the “Disclosing Party”) pursuant to this Agreement except
for that portion of such information that the Receiving Party can demonstrate by competent written proof: 
 (a) was already known to
the Receiving Party or any of its Affiliates, other than under an obligation of confidentiality to the Disclosing Party, at the time of disclosure by the other Party; 

(b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the Receiving Party;

 (c) became generally available to the public or otherwise part of the public domain after its disclosure and other than through
any act or omission of the Receiving Party in breach of this Agreement; 
 (d) is subsequently disclosed to the Receiving Party or
any of its Affiliates by a Third Party without obligations of confidentiality to the Disclosing Party with respect thereto; or 
 (e)
is subsequently independently discovered or developed by the Receiving Party or its Affiliate without the aid, application, access or use of Confidential Information of the Disclosing Party. 

Notwithstanding anything herein to the contrary, on a Program-by-Program
basis, during the Term for such Program, all information relating to the Research, Development, manufacture or Commercialization of Compounds or Products after the Effective Date, and the identity and details of all Programs, shall be treated as the
Confidential Information of BeiGene; provided that all information relating to any Ambrx Technology Platform shall be treated as the Confidential Information of Ambrx, and all information relating to the BeiGene Technology Platforms or BeiGene
Agents shall be treated as the Confidential Information of BeiGene. 

  
 - 58 - 

 10.2 Authorized Disclosure. Each Party may disclose Confidential Information
belonging to the other Party to the extent such disclosure is reasonably necessary in the following situations: 
 (a) filing or
prosecuting Patents in accordance with Article 9; 
 (b) subject to Section 10.3, Regulatory Materials and
other filings with Governmental Authorities (including Regulatory Authorities), including filings with the FDA, as necessary for the Development or Commercialization of Compounds or Products, as required in connection with any filing, application or
request for Regulatory Approval; provided, however, that reasonable measures shall be taken to obtain confidential treatment of such information; 

(c) prosecuting or defending litigation; 

(d) subject to Section 10.3, complying with Applicable Law, including securities laws and regulations promulgated by
securities exchanges; 
 (e) disclosure to its Affiliates, employees, consultants, agents, independent contractors, licensors and any
permitted Sublicensees only on a need-to-know basis and solely in connection with the performance of this Agreement, provided that each disclosee must be bound by
obligations of confidentiality and non-use in writing at least as equivalent in scope as and no less restrictive than those set forth in this Article 10 prior to any such disclosure, provided
further that the term of such disclosee’s obligations regarding confidentiality and non-use may be limited to [***] ([***]) [***] after the date of disclosure to the disclosee; 

(f) disclosure of the material terms of this Agreement to any bona fide potential or actual investor, lender, stockholder, investment
banker, acquirer, merger partner or potential or actual collaborator or partner, legal or financial advisor; provided that each disclosee must be bound by obligations of confidentiality and non-use at least as
equivalent in scope as and no less restrictive than those set forth in this Article 10 prior to any such disclosure, provided further that the term of such disclosee’s obligations regarding confidentiality and non-use may be limited to [***] ([***]) [***] after the date of disclosure to the disclosee; and 

(g) disclosure pursuant to Section 10.5. 

Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information
pursuant to Sections 10.2(a), 10.2(c) or 10.2(d), it will, except where impracticable, give reasonable advance notice to the other Party of such disclosure and use reasonable efforts to secure confidential treatment of such
information. In any event, the Parties agree to take all reasonable action to avoid disclosure of Confidential Information hereunder. 

Nothing in Sections 10.1 or 10.2 shall limit either Party in any way from disclosing to any Third Party such Party’s U.S.
or foreign income tax treatment and the U.S. or foreign income tax structure of the transactions relating to such Party that are based on or derived from this 

  
 - 59 - 

 
Agreement, as well as all materials of any kind (including opinions or other tax analyses) relating to such tax treatment or tax structure, except to the extent that nondisclosure of such matters
is reasonably necessary in order to comply with applicable securities laws. 
 10.3 Publicity; Terms 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 Section 10.2 and this Section 10.3. The Parties have agreed to a public announcement of the execution of this Agreement substantially in the form of the press release
attached as Exhibit E on or after the Effective Date. 
 (b) After issuance of such initial press release, if
either Party desires to make a public announcement concerning the material terms of this Agreement, such Party shall give reasonable prior advance notice of the proposed text of such announcement to the other Party for its prior review and approval
(except as otherwise provided herein), such approval not to be unreasonably withheld, except that in the case of a press release or governmental filing required by Applicable Law (where reasonably advised by the disclosing Party’s counsel), 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. A Party commenting on such a proposed press release shall provide its comments, if any, within [***]
([***]) [***] (or within [***] ([***]) [***] in the event that Ambrx (or its Affiliate) is a public reporting company) after receiving the press release for review and the other Party shall give good faith consideration to same. Ambrx shall have the
right to make a press release announcing the achievement of each milestone under this Agreement as it is achieved, and the achievements of Regulatory Approvals as they occur, subject only to the review procedure set forth in the preceding sentence.
In relation to BeiGene’s review of such an announcement, BeiGene may make specific, reasonable comments on such proposed press release within the prescribed time for commentary, but shall not withhold its consent to disclosure of the
information that the relevant milestone or Regulatory Approval has been achieved and triggered a payment hereunder. Neither Party shall be required to seek the permission of the other Party to repeat any information regarding the terms of this
Agreement that have previously been publicly disclosed by such Party, or by the other Party, in accordance with this Section 10.3. For clarity, neither Party shall disclose the financial terms of this Agreement without the prior written
approval of the other Party, except as and to the extent otherwise expressly permitted under this Agreement. 
 (c) The Parties
acknowledge that either or both Parties may be obligated to file under Applicable Law a copy of this Agreement with the SEC or other Governmental Authorities. Each Party shall be entitled to make such a required filing, provided that it requests
confidential treatment of at least the financial terms and sensitive technical terms hereof and thereof to the extent such confidential treatment is reasonably available to such Party. In the event of any such filing, each Party shall provide the
other Party with a copy of this Agreement marked to show provisions for which such Party intends to seek confidential treatment not less than [***] ([***]) [***] prior to such filing (and any revisions to such portions of the proposed

  
 - 60 - 

 
filing a reasonable time prior to the filing thereof), and shall reasonably consider the other Party’s comments thereon to the extent consistent with the legal requirements, with respect to
the filing Party, governing disclosure of material agreements and material information that must be publicly filed, and shall only disclose Confidential Information which it is advised by counsel or the applicable Governmental Authority is legally
required to be disclosed. No such notice shall be required under this Section 10.3(c) if the substance of the description of or reference to this Agreement contained in the proposed filing has been included in any previous filing made by
either Party hereunder or otherwise approved by the other Party. 
 (d) Each Party shall require each of its Affiliates and private
investors to which Confidential Information of the other Party is disclosed as permitted hereunder to comply with the covenants and restrictions set forth in Sections 10.1 through Section 10.3 as if each such Affiliate and each
such investor were a Party to this Agreement and shall be fully responsible for any breach of such covenants and restrictions by any such Affiliate or investor. 

10.4 Publications. Neither Party shall publicly present or publish results of studies carried out under this Agreement (each
such presentation or publication a “Publication”) without the opportunity for prior review by the other Party, except to the extent otherwise required by Applicable Law, in which case Section 10.3 shall apply with
respect to disclosures required by the SEC and/or for Regulatory Materials. The submitting Party shall provide the other Party the opportunity to review any proposed Publication at least [***] ([***]) [***] prior to the earlier of its presentation
or intended submission for publication. The submitting Party agrees, upon request by the other Party, not to submit or present any Publication until the other Party has had [***] ([***]) [***] to comment on any material in such Publication. The
submitting Party shall consider the comments of the other Party in good faith, but shall retain the sole authority to submit the manuscript for Publication; provided that the submitting Party agrees to delay such Publication as necessary, but no
less than [***] ([***]) [***], to enable the Parties to file a Patent if such Publication might adversely affect such Patent. The submitting Party shall provide the other Party a copy of the Publication at the time of the submission or presentation.
Notwithstanding the foregoing, BeiGene shall not have the right to publish or present Ambrx’s Confidential Information without Ambrx’s prior written consent, and Ambrx shall not have the right to publish or present BeiGene’s
Confidential Information without BeiGene’s prior written consent. Each Party agrees to acknowledge the contributions of the other Party, and the employees of the other Party, in all publications as scientifically appropriate. This
Section 10.4 shall not limit and shall be subject to Section 10.5. 
 10.5 Publication and Listing of
Clinical Trials and Compliance with other Policies, Orders and Agreements. The Parties agree to comply, with respect to Compounds and Products, with (a) the Pharmaceutical Research and Manufacturers of America (PhRMA) Guidelines on the
listing of Clinical Trials and the Publication of Clinical Trial results, and (b) any applicable court order, stipulations, consent agreements and settlements entered into by a party. 

  
 - 61 - 

 10.6 Effect of Change of Control. If a Party or any of its Affiliates merges
or consolidates with, is otherwise acquired by, or acquires, a Third Party (including through a Change of Control), unless the other Party otherwise agrees in writing, such Party shall take reasonable steps to limit data access and sharing between
its personnel working on other research programs and its personnel working on the Programs or having access to data from the Programs or any of the other Party’s Confidential Information. 

11. TERM AND TERMINATION 

11.1 Term. This Agreement shall become effective on the Effective Date and, unless earlier terminated pursuant to this
Article 11, shall continue, on a Program-by-Program, Compound-by-Compound, Product-by-Product and country-by-country basis at the end of the applicable Royalty Term with
respect to such Product in such country (the “Term”). Upon the expiration of the Royalty Term with respect to a Product in a country, the licenses granted to BeiGene under this Agreement will become exclusive, perpetual,
irrevocable, fully paid-up and royalty-free with respect to such Product in such country. 

11.2 Termination by BeiGene at Will. BeiGene may terminate this Agreement as a whole or on a Program-by-Program, Compound-by-Compound, Product-by-Product and/or country-by-country basis, effective upon [***] ([***]) [***] prior written notice to Ambrx. Following
any such notice of termination under this Section 11.2 for a Research Program, for the period ending [***] ([***]) [***] following the effective date of the notice of termination, BeiGene shall be responsible for the payment for (a)
[***] and (b) [***]; provided that, in each case, Ambrx shall use its good faith and commercially reasonable efforts to avoid, cancel or otherwise limit such Third Party Costs incurred by Ambrx after BeiGene’s notice of termination. In the
event that this Agreement is terminated only with respect to a given Program, Compound, Product or a given country pursuant to this Section 11.2, then the effects of termination as set forth in Sections 11.9 and 11.10
shall only apply with respect to such Program, Compound, Product or such country, as applicable. 
 11.3 Termination by Either Party for
Breach. 
 (a) Either Party may terminate this Agreement in its entirety, with respect to any Compound (on a Compound-by-Compound basis), Product (on a Product-by-Product basis) or with respect to any
Program (on a Program-by-Program basis) as to the entire Territory or with respect to any country (on a
country-by-country basis), in the event the other Party materially breaches this Agreement as it relates to a particular Compound, Product, Program or country, and such
breach shall have continued for [***] ([***]) [***] (or [***] ([***]) [***] for a breach of payment obligations) (or, if such default cannot be cured within such [***] ([***]) [***] period (or [***] ([***]) [***] period for a breach of payment
obligations), if the alleged breaching Party has not commenced and diligently continued good faith efforts to cure such breach) after written notice shall have been provided to the breaching Party by the
non-breaching Party requiring such breach to be remedied and stating an intention to terminate if not so cured. Except as set forth in Section 11.3(b), any such termination shall become effective
at the end of 

  
 - 62 - 

 
such [***] ([***]) [***] period (or [***] ([***]) [***] period for a breach of payment obligations) unless the breaching Party has cured any such breach prior to the expiration of the [***]
([***]) [***] (or [***] ([***]) [***]) period (or, if such default cannot be cured within such [***] ([***]) [***] (or thirty (30) day) period, if the alleged breaching Party has not commenced and diligently continued good faith efforts to cure
such breach). In the event that this Agreement is terminated only with respect to a given Compound, Product and/or a given country and/or a given Program pursuant to this Section 11.3, then the effects of termination as set forth in
Section 11.9 and 11.10 shall only apply with respect to such Compound, Product, country or Program, as applicable. 

(b) Section 11.3(a) shall not apply to or encompass a breach (or alleged breach) of BeiGene’s obligation to use
Commercially Reasonable Efforts as set forth in Section 4.1 or 5.1, and for which a remedy, if any, for any such breach shall be governed solely by Section 11.4. 

(c) 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 such [***] ([***]) [***] or [***] ([***]) [***] period, then
the cure periods set forth in Section 11.3(a) shall be tolled during the pendency of the dispute resolution process as set forth in Article 14 and the
non-breaching Party shall not have the right to terminate this Agreement under Section 11.3(a) unless and until such dispute resolution process has been completed (including the
tolling and cure periods set forth therein). 
 (d) Alternative to BeiGene’s Termination Under
Section 11.3(a). Notwithstanding any other provisions of this Agreement and in addition to the deductions otherwise permitted under this Agreement, subject to Section 11.3(c), if BeiGene has the right to
terminate this Agreement under Section 11.3(a) (including expiration of all applicable cure periods thereunder and following the dispute resolution process as set forth in Section 11.3(c) and
Article 14, if applicable), in lieu of exercising such termination right, BeiGene may elect by written notice to Ambrx before the end of such applicable cure period to have this Agreement continue in full force and effect
and [***]. 
 (e) Ongoing Research Activities. In addition to BeiGene’s rights under Section 11.3(d), subject
to Section 11.3(c), if BeiGene has the right to terminate this Agreement under Section 11.3(a) (including expiration of all applicable cure periods thereunder and following the dispute resolution process as set forth in
Section 11.3(c) and Article 14, if applicable) due to Ambrx’s material breach of its obligations under the Agreement, then in lieu of exercising such termination right, BeiGene may elect to continue the
performance of the Agreement and the Research Program and will have the right, but not the obligation, to [***]; provided that in no event shall [***]. Ambrx hereby grants and will grant to BeiGene, effective after it has been determined that
pursuant to Section 11.3(c) and Article 14 BeiGene has the right to terminate this Agreement under Section 11.3(a) and upon the date BeiGene notifies Ambrx

  
 - 63 - 

 
that [***]. In the event that BeiGene exercises its rights pursuant to this Section 11.3(e), the Parties will [***]. 

11.4 Termination for Failure to Use Commercially Reasonable Efforts. Subject to Sections 11.9 and
11.10, Ambrx shall have the right to terminate this Agreement on a Licensed Program-by-Licensed Program basis if BeiGene is in material breach of its obligation
to use Commercially Reasonable Efforts as set forth in Section 4.1 or 5.1 with respect to such Licensed Program; provided, however, such license for such Licensed Program shall not so terminate unless (a) BeiGene is
given [***] ([***]) [***] prior written notice by Ambrx of Ambrx’s intent to terminate, stating the reasons and justification for such termination and recommending steps which Ambrx believes BeiGene should take to cure such alleged breach, and
(b) BeiGene, or its Affiliates or Sublicensee, has not (i) during the [***] ([***]) [***] period following such notice, provided Ambrx with a plan for the Development and/or Commercialization of the Compound or Product in the Field as set
forth in Sections 4.1 and 5.1 and (ii) during the [***] ([***]) [***] period following such notice carried out such plan and cured such alleged breach by using Commercially Reasonable Efforts to pursue the Development or
Commercialization of the Compound or Product for such Licensed Program in the Field as set forth in Sections 4.1 and 5.1. Notwithstanding the foregoing, if BeiGene disputes in good faith the existence or materiality of the alleged
breach of its obligation to use Commercially Reasonable Efforts as set forth in Section 4.1 or 5.1 with respect to such Licensed Program, the terms of Section 11.3(c) shall apply to such dispute, mutatis
mutandis. In the event that this Agreement is terminated only with respect to a given Licensed Program pursuant to this Section 11.4, then the effects of termination as set forth in Section 11.9 shall only apply with
respect to such Licensed Program. 
 11.5 Termination by Either Party for Insolvency. A Party shall have the right to
terminate this Agreement upon written notice if the other Party incurs an Insolvency Event; provided, however, in the case of any involuntary bankruptcy proceeding, such right to terminate shall only become effective if the Party that incurs the
Insolvency Event consents to the involuntary bankruptcy or if such proceeding is not dismissed or stayed within [***] ([***]) [***] after the filing thereof. “Insolvency Event” means circumstances under which a Party (a) has a
receiver or similar officer appointed over all or a material part of its assets or business; (b) passes a resolution for winding-up of all or a material part of its assets or business (other than a winding-up for the purpose of, or in connection with, any solvent amalgamation or reconstruction) or a court enters an order to that effect; (c) has entered against it an order for relief recognizing it as a
debtor under any insolvency or bankruptcy laws (or any equivalent order in any jurisdiction); or (d) enters into any composition or arrangement with its creditors with respect to all or a material part of its assets or business (other than
relating to a solvent restructuring). 
 11.6 Termination for Safety Reasons. BeiGene shall have the right, on a Program-by-Program, Compound-by-Compound or Product-by-Product basis, to terminate this Agreement, at any time after the Effective Date, with respect to such Program, Compound or Product in the Territory upon providing [***] ([***]) [***] prior written
notice to Ambrx (a) if BeiGene determines in good faith that the risk/benefit profile of the Program, Compound or 

  
 - 64 - 

 
Product is such that the Program, Compound or Product cannot continue to be Developed or administered to patients safely; or (b) upon the occurrence of serious adverse events related to the
use of the Compound or Product that cause BeiGene to conclude that the continued use of the Compound or Product by patients will result in patients being exposed to a product in which the risks outweigh the benefits. During the [***] ([***]) [***]
notice period, the Parties shall begin to wind-down their respective activities under the Agreement to the extent related to the Program, Compound or Product. 

11.7 Cessation of Development or Commercialization. On a Licensed Program-by-Licensed Program basis, Ambrx may, at its election, terminate this Agreement with respect to such Licensed Program upon thirty (30) days’ prior written notice to BeiGene in the event that
BeiGene, itself or through its Affiliates or Sublicensees, do not conduct any Development or Commercialization activities with respect to Compounds or Products for such Licensed Program for a continuous period of more than [***] ([***]) [***];
provided that (a) if such cessation is a result of a Safety Concern, Regulatory Event (including a clinical hold), force majeure, or restraining order or injunction, such [***] ([***]) [***] period will be extended for each day any of
the foregoing listed in this clause (a) caused such cessation and (b) if such cessation of activity is due to a manufacturing issue and BeiGene or its Affiliates or Sublicensees is diligently seeking to remedy such issue, such [***]
([***]) [***] period will be extended for a reasonable period of time as is reasonably necessary to resolve the manufacturing issue. 

11.8 Limitations on Termination Remedy. 

(a) Notwithstanding anything herein to the contrary, in the event that this Agreement is terminated pursuant to
Section 11.3 or 11.4 with respect to a Product, to the extent the material breach affects only a specific country in the Territory, then this Agreement may only be terminated for such Product in such country. 

(b) For avoidance of doubt, any termination under this Article 11 with respect to a particular Program, Compound, Product
or country shall have no effect on and shall not in any way limit the licenses granted under this Agreement to BeiGene for Programs, Compounds and Products with respect to any other Programs or with respect to any other country. 

11.9 Effects of Termination of this Agreement. Upon termination of this Agreement, the following shall apply with respect to the
terminated Program(s), terminated Compound(s), terminated Product(s) or terminated country(ies) (in addition to any other rights and obligations under this Agreement with respect to such termination). For clarity, if this Agreement is terminated
only with respect to a given Compound(s), Product(s) and/or a given country(ies) and/or a given Program(s), as applicable, then the following provisions of this Section 11.9 shall only apply with respect to such Compound, Product and/or
such country and/or such Program, as applicable. 
 (a) Cessation of Rights. Except for the rights and licenses granted under
this Section 11.9 or Section 11.10, all rights and licenses granted by either Party to the other Party 

  
 - 65 - 

 
and all obligations under this Agreement shall terminate with respect to the Program(s), Compound(s), Product(s) and/or country(ies), as applicable, in which the termination becomes effective;
provided that any sublicenses granted by BeiGene pursuant to Section 7.2 shall remain in effect and become direct licenses from Ambrx to the applicable Sublicensees, so long as actions and omissions by the applicable Sublicensee did not
cause or contribute to such termination and such Sublicensee is not then in material breach of its sublicense agreement. Subject to Section 11.10, each Party and its Affiliates and Sublicensees shall cease all use of the Ambrx IP, Ambrx
Technology Platform IP, BeiGene IP, BeiGene Technology Platform IP, BeiGene Agent IP or Compound IP, as applicable, with respect to such Program(s), Compound(s), Product(s) or country(ies), and shall cease all Research with respect to such Research
Program(s) and shall cease all Development with respect to such Compound(s) or Product(s) and Commercialization with respect to such Product(s) in the applicable terminated countries, as applicable. 

(b) Licenses. BeiGene shall retain a non-exclusive, worldwide license under

(a) Regulatory Materials. Upon Ambrx’s written request, BeiGene shall [***], and shall take such actions and execute such
other instruments, assignments and documents as may be reasonably necessary to [***]. The Parties shall effect [***] within [***] ([***]) [***] after the applicable effective date of termination, unless otherwise mutually agreed in writing. During

employees, and agents (the “BeiGene Indemnitees”) harmless from and against any and all liabilities, losses, costs, damages, fees, expenses or other amounts payable to a Third
Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by such BeiGene Indemnitees (collectively, “BeiGene Damages”), all to the extent resulting from any claims, suits, proceedings or causes
of action brought by or on behalf of such Third Party (collectively, “BeiGene Claims”) against such BeiGene Indemnitee that arise out of or result from (or are alleged to arise out of or result from): (a) a breach of any of
Ambrx’s representations, warranties, covenants or obligations under this Agreement; (b) the gross negligence or willful misconduct of Ambrx or its Affiliates or any of their respective officers, directors, employees, or agents;
(c) the Exploitation of (i) any Compounds or Products by or on behalf of Ambrx or its Affiliates prior to the Effective Date or during the Term or (ii) the Exploitation of any Reversion Products by or on behalf of Ambrx or its
Affiliates, subcontractors or sublicensees after the Term; (d) the violation of Applicable Law by any Ambrx Indemnitee; or (e) any breach by Ambrx or its Affiliates of, or any failure by Ambrx or its Affiliates, or their respective
contractors or agents, to perform, observe or comply with any of the provisions of, an Existing License Agreement, except to the extent that such failure is attributable to a breach by BeiGene of its obligations under this Agreement. The foregoing
indemnity obligation shall not apply to the extent that any BeiGene Claim is subject to indemnity pursuant to Section 13.2. 

13.2 Indemnification by BeiGene for Third Party Claims. BeiGene shall defend, indemnify, and hold Ambrx, its Affiliates, and its
and their respective officers, directors, employees, and agents, (the “Ambrx Indemnitees”) harmless from and against any and all liabilities, losses, costs, damages, fees, expenses or other amounts payable to a Third Party claimant,
as well as any reasonable attorneys’ fees and costs of litigation incurred by such Ambrx Indemnitees (collectively, “Ambrx Damages”), all to the extent resulting from any claims, suits, proceedings or causes of action brought
by or on behalf of such Third Party (collectively, “Ambrx Claims”) against such Ambrx Indemnitee that arise out of or result from (or are alleged to arise out of or result from): (a) the Exploitation of any Compounds, or Products by
or on behalf of BeiGene or its Affiliates or Sublicensees during the Term; (b) a breach of any of BeiGene’s representations, warranties, covenants or obligations under this Agreement; or (c) the gross negligence or willful misconduct
of BeiGene or its Affiliates or Sublicensees, or any of their respective officers, directors, employees, or agents; or (d) the violation of Applicable Law by any BeiGene Indemnitee. The foregoing indemnity obligation shall not apply to the
extent that any Ambrx Claim is subject to indemnity pursuant to Section 13.1. 
 13.3 Indemnification Procedures.
The Party claiming indemnity under this Article 13 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) promptly after
learning of the claim, suit, proceeding or cause of action for which indemnity is being sought (“Claim”), and, provided that the Indemnifying Party is not contesting the indemnity obligation, shall permit the Indemnifying Party to
control and assume the defense of any litigation relating to such claim and disposition of any such Claim unless the Indemnifying Party is also a party (or likely to be named a party) to the proceeding in which such claim is made and the Indemnified
Party gives notice to the 

  
 - 73 - 

 
Indemnifying Party that it may have defenses to such claim or proceeding that are in conflict with the interests of the Indemnifying Party, in which case the Indemnifying Party shall not be so
entitled to assume the defense of the case. If the Indemnifying Party does assume the defense of any Claim, it (a) shall act diligently and in good faith with respect to all matters relating to the settlement or disposition of any Claim as the
settlement or disposition relates to Parties being indemnified under this Article 13, (b) shall cause such defense to be conducted by counsel reasonably acceptable to the Indemnified Party and (c) shall not settle or otherwise
resolve any Claim without prior notice to the Indemnified Party and the consent of the Indemnified Party if such settlement involves anything other than the payment of money by the Indemnifying Party. The Indemnified Party shall reasonably cooperate
with the Indemnifying Party in its defense of any claim for which the Indemnifying Party has assumed the defense in accordance with this Section 13.3, and shall have the right (at its own expense) to be present in person or through
counsel at all legal proceedings giving rise to the right of indemnification. The Indemnified Party shall not settle any such Claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld. The
Indemnifying Party’s obligation to defend, indemnify, and hold harmless pursuant to Section 13.1 or Section 13.2, as applicable, will be reduced to the extent the Indemnified Party’s
delay in providing notification pursuant to the previous sentence results in material prejudice to the Indemnifying Party; provided, however, that the failure by an Indemnified Party to give such notice or otherwise meet its obligations under this
Section 13.3 will not relieve the Indemnifying Party of its indemnification obligation under this Agreement. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (i) the
Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to the 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 (ii) the Indemnifying Party will remain responsible to indemnify the Indemnified Party as provided in this Article 13. 

13.4 Limitation of Liability. EXCEPT FOR (A) INDIRECT (INCLUDING LOST PROFITS), INCIDENTAL, SPECIAL, PUNITIVE, EXEMPLARY OR
CONSEQUENTIAL DAMAGES PAID OR PAYABLE TO A THIRD PARTY BY AN INDEMNIFIED PARTY FOR WHICH THE INDEMNIFIED PARTY IS ENTITLED TO INDEMNIFICATION HEREUNDER, (B) A BREACH OF SECTION 7.7, (C) ANY BREACH OF ANY OF ARTICLE 10 OR

FOR ANY INDIRECT, INCIDENTAL, SPECIAL, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES, WHETHER BASED UPON A CLAIM OR ACTION OF CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY OR OTHER TORT, OR OTHERWISE,

  
 - 74 - 

 
ARISING OUT OF THIS AGREEMENT REGARDLESS OF ANY NOTICES OF THE POSSIBILITY OF SUCH DAMAGES. 

13.5 Insurance. 

(a) BeiGene shall procure and maintain insurance (or self-insure), including general liability insurance and product liability

such Party at all times during which any Compounds or Products is being clinically tested in human subjects or commercially distributed or sold and for five (5) years after the last Product is Commercialized. 

(b) If Ambrx exercise its right to obtain the license on Reversion Products from BeiGene pursuant to Section 11.10(e) after

not be construed to create a limit of each such Party’s liability with respect to its indemnification obligations under this Article 13. Each Party shall provide the other Party with written evidence of such insurance upon request.
Each Party may not cancel or make material change in such insurance without the other Party’s prior written consent. 
 14. DISPUTE
RESOLUTION 
 14.1 Disputes; Resolution by Executive Officers. The Parties recognize that disputes as to certain matters
may from time to time arise during the Term that relate to decisions to be made by the Parties herein or to the Parties’ respective rights and/or obligations hereunder. It is the desire of the Parties to establish procedures to facilitate the
resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Article 14 if and when a dispute arises under
this Agreement, subject to Section 14.6. Accordingly, any disputes, controversies or differences, other than a matter within the final decision-making authority of Ambrx or BeiGene, which may arise between the Parties out of or in
relation to or in connection with this Agreement, 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 between the Executive Officers of each Party within 

  
 - 75 - 

 
[***] ([***]) [***] after receipt by the other Party of such written notice. If the matter is not resolved within [***] ([***]) [***] following presentation to the Executive Officers, then either
Party may invoke the provisions of Section 14.2. 
 14.2 Arbitration. Subject to Section 14.3 and
Section 14.9, any dispute that is not resolved pursuant to Section 14.1, shall be settled by binding arbitration to be conducted as set forth below in this Section 14.2. 

(a) Either Party, following the end of the [***] ([***]) [***] period referenced in Section 14.1, may refer such issue to
arbitration by submitting a written notice of such request to the other Party. In any proceeding under this Section 14.2, there shall be three (3) arbitrators. Within [***] ([***]) [***] after delivery of such notice, each Party
will nominate one arbitrator in accordance with the then current rules of the American Arbitration Association (the “AAA”). The two arbitrators so nominated will nominate a third arbitrator to serve as chair of the arbitration
tribunal, such nomination to be made within [***] ([***]) [***] after the selection of the second arbitrator. The arbitrators shall be neutral and independent of both Parties and all of their respective Affiliates, shall have significant experience
and expertise in licensing and partnering agreements in the pharmaceutical and biotechnology industries, shall have appropriate experience with respect to the matter(s) to be arbitrated, and shall have some experience in mediating or arbitrating
issues relating to such agreements. In the case of any dispute involving an alleged failure to use Commercially Reasonable Efforts, the arbitrators shall in addition be an individual with experience and expertise in the worldwide development and
commercialization of pharmaceuticals and the business, legal and scientific considerations related thereto. In the case of a dispute involving a scientific or accounting matter or determination, an Expert having applicable expertise and experience
will be selected by the Parties to assist the arbitrators in such scientific or accounting matter or determination (and the arbitrators will select such Expert if the Parties cannot agree on such Expert within [***] ([***]) [***] following the
selection of the arbitrators). The governing law in Section 15.8 shall govern such proceedings. No individual shall be appointed to arbitrate a dispute pursuant to this Agreement unless he or she agrees in writing to be bound by the
provisions of this Section 14.2. The place of arbitration will be New York City, the State of New York, unless otherwise agreed to by the Parties, and the arbitration shall be conducted in English. 

(b) The arbitrators shall set a date for a hearing that shall be held no later than [***] ([***]) [***] following the appointment of
the last of such three arbitrators. The Parties shall have the right to be represented by counsel. Except as provided herein, the arbitration shall be governed by the Commercial Arbitration Rules of the AAA applicable at the time of the notice of
arbitration pursuant to Section 14.2(a), including the right of each Party to undertake document requests and up to [***] ([***]) depositions. 

(c) The arbitrators shall use their best efforts to rule on each disputed issue within thirty (30) days after completion of the
hearing described in Section 14.2(b). The determination of the arbitrators as to the resolution of any dispute shall be binding and conclusive upon the Parties, absent manifest error. All rulings of the arbitrators shall be in writing
and shall be delivered to the Parties as soon as is reasonably possible. Nothing contained 

  
 - 76 - 

 
herein shall be construed to permit the arbitrators to award punitive, exemplary or any similar damages. The arbitrators shall render a “reasoned decision” within the meaning of the
Commercial Arbitration Rules which shall include findings of fact and conclusions of law. Any arbitration award may be entered in and enforced by a court in accordance with Section 14.2(a) and Section 14.9. 

14.3 Expedited Arbitration. If a Party exercises its rights under this Agreement to refer a dispute to expedited arbitration (an
“Expedited Dispute”), then the Parties will follow the expedited dispute resolution process in this Section 14.3 (and not the dispute resolution process in Section 14.1)
(“Expedited Arbitration”). The Parties agree and acknowledge that any good faith dispute under Expedited Arbitration will not be deemed to be a material breach of this Agreement. The Expedited Dispute will be submitted to
fast-track, binding arbitration in accordance with the following. 
 (a) Arbitration will be conducted in New York, New York under
the rules of the AAA for the resolution of commercial disputes in the most expedited manner permitted by such rules. The Parties will appoint a single arbitrator to be selected by mutual agreement. If the Parties are unable to agree on an
arbitrator, the Parties will request that the AAA select the arbitrator. The arbitrator will be an Expert where expressly set forth under this Agreement and otherwise will be a professional in business or licensing experienced in the valuation of
biopharmaceutical products with at least ten (10) years of experience in the pharmaceutical and life sciences industries, including the conduct of research, development and commercialization collaborations. Except in a proceeding to enforce the
results of the arbitration or as otherwise required by Applicable Law, neither BeiGene nor Ambrx nor any arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written agreement of BeiGene and Ambrx.

 (b) Within [***] ([***]) [***] after such matter is referred to arbitration, each Party will provide the arbitrator with a
proposal and written memorandum in support of its position regarding the Expedited Dispute, as well as any documentary evidence it desires to provide in support thereof (each, a “Brief”) and the arbitrator will provide each
Party’s Brief to the other Party after it receives it from each Party. 
 (c) Within thirty (30) days after a Party submits
its Brief, the other Party will have the right to respond thereto. The response and any material in support thereof will be provided to the arbitrator and the other Party. 

(d) The arbitrator will have the right to meet with the Parties as necessary to inform the arbitrator’s determination and to
perform independent research and analysis. Within [***] ([***]) [***] after the receipt by the arbitrator of both Parties’ responses (or expiration of the [***] ([***]) [***] period if any Party fails to submit a response), then the arbitrator
will deliver his/her decision regarding the Expedited Dispute in writing, which decision will be made in accordance with the standard for resolution of such matter set forth in this Agreement; provided that the arbitrator will select one of the
resolutions proposed by the Parties.

 14.4 Award. Any award to be paid by one Party to the other Party as determined
by the arbitrators as set forth above under Section 14.1 or Section 14.3 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. Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Article 14, and agrees that, subject to the Federal
Arbitration Act, judgment may be entered upon the final award in a court of competent jurisdiction and that other courts may award full faith and credit to such judgment in order to enforce such award. With respect to money damages, nothing
contained herein shall be construed to permit the arbitrators or any court or any other forum to award punitive or exemplary damages. By entering into this agreement to arbitrate, the Parties expressly waive any claim for punitive or exemplary
damages. The only damages recoverable under this Agreement are compensatory damages. 
 14.5 Costs. Each Party shall bear its
own legal fees in connection with any arbitration procedure. The arbitrators may in their discretion assess the arbitrators’ cost, fees and expenses (and those any Expert hired by the arbitrators) against the Party losing the arbitration. 

14.6 Injunctive Relief. Nothing in this Article 14 will preclude either Party from seeking equitable relief or
interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to
protect the interests of such Party or to preserve the status quo pending the arbitration proceeding. For the avoidance of doubt, nothing in this Section 14.6 shall otherwise limit a breaching Party’s opportunity to cure a material
breach as permitted in accordance with Section 11.3 or Section 11.3(d).  
 14.7
Confidentiality. The arbitration proceeding shall be confidential and the arbitrators shall issue appropriate protective orders to safeguard each Party’s Confidential Information. Except as required by Applicable Law, no Party shall make
(or instruct the arbitrators to make) any public announcement with respect to the proceedings or decision of the arbitrators without prior written consent of the other Party. The existence of any dispute submitted to arbitration, and any award,
shall be kept in confidence by the Parties and the arbitrators, except as required in connection with the enforcement of such award or as otherwise required by Applicable Law. 

14.8 Survivability. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of
this Agreement for any reason. 
 14.9 Patent and Trademark Disputes. Notwithstanding Section 14.2, any dispute,
controversy or claim relating to the inventorship, scope, validity, enforceability or infringement of any Patents or trademarks Covering the manufacture, use, importation, offer for sale or sale of Products shall be submitted to a court of competent
jurisdiction in the country in which such patent or trademark rights were granted or arose. 
 15. MISCELLANEOUS

 15.1 Entire Agreement; Amendments. This Agreement, including the Exhibits
hereto (which are incorporated into and made a part of this Agreement), sets forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the
Parties hereto with respect to the subject matter hereof and supersedes, as of the Effective Date, all prior agreements and understandings between the Parties with respect to the subject matter hereof, including that Confidentiality Agreement
between BeiGene and Ambrx, dated as of [***] (provided that all information disclosed or exchanged under such agreement will be treated as Confidential Information hereunder). There are no covenants, promises, agreements, warranties,
representations, conditions or understandings, either oral or written, between the Parties other than as are set forth herein and therein. No subsequent alteration, amendment, change or addition to this Agreement (including to any Exhibit hereto)
shall be binding upon the Parties unless reduced to writing and signed by an authorized representative of each Party. 
 15.2 Rights in
Bankruptcy.  
 (a) All rights and licenses granted under or pursuant to this Agreement by one Party to the
other are, for all purposes of Section 365(n) 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 (a) before this
Agreement is rejected by or on behalf of the Bankrupt Party, within [***] ([***]) [***] after the other Party’s written request, unless the Bankrupt Party, or its trustee or receiver, elects within [***] ([***]) [***] to continue to perform all
of its obligations under this Agreement, or (b) after any rejection of this Agreement by or on behalf of the Bankrupt Party, if not previously delivered as provided under clause (a) above. All rights of the Parties under this
Section 15.2 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 Law.
The non-Bankrupt Party shall have the right to perform the obligations of the Bankrupt Party hereunder with respect to such intellectual property, but neither such provision nor such performance by the non-Bankrupt Party shall release the Bankrupt Party from any such obligation or liability for failing to perform it. 

(b) The Parties agree that they intend the foregoing non-Bankrupt Party rights to extend to the
maximum extent permitted by law and any provisions of applicable contracts with Third Parties, including for purposes of Title 11, (i) the right of access to any intellectual property (including all embodiments thereof) of the Bankrupt Party or any
Third Party with whom the Bankrupt Party contracts to perform an obligation of the Bankrupt Party under this 

  
 - 79 - 

 
Agreement, and, in the case of the Third Party, which is necessary for the Development, Regulatory Approval and manufacture of Products and (ii) the right to contract directly with any Third
Party described in (i) in this sentence to complete the contracted work. 
 (c) Any intellectual property provided pursuant to
the provisions of this Section 15.2 shall be subject to the licenses set forth elsewhere in this Agreement and the payment obligations of this Agreement, and the royalties under Section 8.5 shall be deemed to be royalties for
purposes of Title 11. 
 (d) In the event that after the Effective Date Ambrx enters into a license agreement with a Third Party with
respect to intellectual property that will be sublicensed to BeiGene hereunder, Ambrx will use commercially reasonable efforts to enable BeiGene to receive a direct license from any such Third Party in the event that such license agreement between
Ambrx and such Third Party is terminated during the Term solely on account of Ambrx becoming a Bankrupt Party. 
 (e) Notwithstanding
anything to the contrary in Article 9, in the event that Ambrx is the Bankrupt Party, BeiGene may take appropriate actions in connection with the filing, prosecution, maintenance and enforcement of any Ambrx Patent rights licensed or assigned
to BeiGene under this Agreement without being required to consult with Ambrx before taking any such actions, provided that such actions are consistent with this Agreement. 

15.3 Force Majeure. Each Party shall be excused from the performance of its obligations under this Agreement, except for
obligations to make payments, to the extent that such performance is prevented by force majeure (defined below) and the nonperforming Party promptly provides notice of such prevention to the other Party. Such excuse shall be continued so long as the
condition constituting force majeure continues. The Party affected by such force majeure also shall notify the other Party of the anticipated duration of such force majeure, any actions being taken to avoid or minimize its effect after such
occurrence, and shall take reasonable efforts to remove the condition constituting such force majeure and to resume performance of its obligations hereunder. For purposes of this Agreement, “force majeure” means conditions beyond
the control of the Parties, potentially including an act of God, acts of terrorism, war, acts of war (whether war be declared or not), labor strike or lock-out, civil commotion, epidemic, failure or default of
public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe. The payment of invoices due and owing hereunder shall in no event be delayed by the payer because of a force
majeure affecting the payer. 
 15.4 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 15.4,
and shall be deemed to have been given for all purposes (a) when received, if hand delivered or sent by a reputable international expedited

 15.5 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. 
 15.6 Maintenance of Records. Each Party shall maintain complete and accurate
records of all work conducted under this Agreement and all results, data and developments made pursuant to its efforts under this Agreement. Such records shall be complete and accurate and shall fully and properly reflect all work done and results
achieved in the performance of this Agreement in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes. Each Party shall maintain such records for a period of [***] ([***]) [***] after such records are

property rights. Each Party shall keep and maintain all records required by Applicable Law with respect to Products. 
 15.7
Assignment. Neither Party may assign this Agreement or assign or transfer, in whole or in part, any rights or obligations hereunder without the prior written consent of the 

  
 - 81 - 

 
other, which consent will not be unreasonably withheld, conditioned or delayed, except that a Party may make such an assignment or transfer, in whole or in part, without the other Party’s
consent (a) to any Affiliate of such Party, or (b) to any Third Party successor in interest or purchaser of all or substantially all of the business or assets of such Party to which this Agreement relates (or if this Agreement is assigned
in part, to which such part of this Agreement relates), whether in a merger, combination, consolidation, reorganization, sale of stock, sale of assets or other transaction; provided, however, that in each case (a) and (b) that the assigning
Party provides written notice to the other Party of such assignment and the assignee shall have agreed in writing to be bound (or is otherwise required by operation of Applicable Law to be bound) in the same manner as such assigning Party hereunder.
Any permitted assignment shall be binding on the successors or heirs of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this Section 15.7 shall be null, void and of no legal
effect. 
 15.8 Governing Law. This Agreement shall be governed by and construed and enforced under the substantive laws of
the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise make this Agreement subject to the substantive law of another jurisdiction. For clarification, any dispute relating to the validity,
enforceability or infringement of any Patent shall be governed by and construed and enforced in accordance with the patent laws of the applicable jurisdiction. 

15.9 Performance by Affiliates. Subject to the terms and conditions of this Agreement, each Party may discharge any obligations
and exercise any rights (including granting or continuing licenses and other rights) hereunder through one or more of its Affiliates. Subject to an assignment to such Affiliate pursuant to Section 15.7, in any event
each Party will remain responsible for the acts and omissions, including financial liabilities, of its Affiliates. Each Party hereby expressly waives any requirement that the other Party exhaust any right, power or remedy, or proceed against any of
the first Party’s Affiliates for any obligation or performance hereunder, prior to proceeding directly against such Party. 

15.10 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. 
 15.11 Compliance with
Applicable Law. Each Party shall comply with Applicable Law in the course of performing its obligations or exercising its rights pursuant to this Agreement. Neither Party (nor any of their Affiliates) shall be required under this Agreement to
take any action or to omit to take any action otherwise required to be taken or omitted by it under this Agreement if the taking or omitting of such action, as the case may be, could in its opinion violate any settlement, consent order, corporate
integrity agreement, or judgment to which it may be subject from time to time during the Term. Notwithstanding anything to the contrary in this Agreement, neither Party nor any of its Affiliates shall be required to take, or shall be penalized for
not taking, any action that such Party reasonably believes is not in compliance with Applicable Law. 

  
 - 82 - 

 15.12 Severability. If any one or more of the provisions of this Agreement are
held to be invalid or unenforceable by an arbitrator or 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. 

15.13 No Waiver. Neither Party may waive or release any of its rights or interests in this Agreement except in writing. The
failure of either Party to assert (or delay in asserting) a right hereunder or to insist (or delay in insisting) upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent
failure to perform any such term or condition. No waiver by either Party of any condition or term in any one or more instances shall be construed as a continuing waiver of such condition or term or of another condition or term. 

15.14 Interpretation. The captions and headings to this Agreement are for convenience only, and are to be of no force or effect
