(f) Dispute Resolution. If the JDC cannot reach consensus with regard to any matter within its authority within [***] Business Days
after such matter has been brought to the JDC’s attention, then such matter shall be referred to the Executive Officers, who shall promptly meet and attempt in good faith to resolve such issue within [***] Business Days from the date upon which
such matter is referred to them. In the event that the Executive Officers are unable to resolve such issue within [***] Business Days of the issue being referred to them, then, subject to Section 3.2(g) below, Artiva’s Executive
Officer shall have the tie-breaking vote. 
 (g) Limitation on Authority. The JDC shall have
only such rights, powers and authority as are expressly delegated to it under this Agreement, and the JDC shall not be a substitute for the rights of the Parties hereunder. Notwithstanding any other provision of this Agreement to the contrary, the
JDC shall not have any right, power or authority: 
 (i) to determine any issue in a manner that would conflict with the express
terms and conditions of this Agreement; or 
 (ii) to modify or amend the terms and conditions of this Agreement.

 3.3 Alliance Managers. Within thirty (30) days after the Effective Date, each
Party shall appoint and notify the other Party of the identity of a representative having the appropriate authority and qualifications, including a general understanding of pharmaceutical development and commercialization issues, to act as its
alliance manager under this Agreement (the “Alliance Manager”). The Alliance Managers shall be primarily responsible for facilitating the flow of information and otherwise promoting communication and coordination between the
Parties. Each Party may replace its Alliance Manager at any time upon written notice to the other Party. 
  

	4.	 R&D PROGRAM 

4.1 Objective. Subject to the terms and conditions of this Agreement, GCLC shall perform a program of discovery, research and
preclinical development and manufacture of Selected Products to generate and identify Option Candidates (the “R&D Program”). 

4.2 R&D Plan. 
 (a)
The discovery, research and preclinical development and manufacturing activities (including process development) to be conducted by GCLC (and, as applicable, GCLC Affiliates) in furtherance of the R&D Program, including the resources and
estimated timeline for performance of such activities, shall be set forth in a mutually agreed, written research and development plan (as may be updated or amended, the “R&D Plan”), the initial version of which
will be agreed to by the Parties within [***] days of the Effective Date. The R&D Plan shall be subject to amendment from time to time by the JSC in accordance with Section 3.1. 

(b) GCLC shall be solely responsible, at its own expense, for all activities under the R&D Plan; provided that Artiva shall
bear all costs for completing IND-enabling activities (such as preclinical toxicology and then-current good manufacturing practices production) performed by GCLC on behalf of Artiva (excluding [***]). 

4.3 Performance of R&D Program. GCLC shall, and shall cause any GCLC Affiliates involved in the R&D Program to, perform the
R&D Program in accordance with the R&D Plan and the terms and conditions of this Agreement. In addition, GCLC shall, and shall cause such GCLC Affiliates to: 

(a) perform all R&D Program activities in good scientific manner and in compliance with all applicable Laws; 

(b) use Commercially Reasonable Efforts to perform R&D Program activities substantially in accordance with the timeline for such
activities set forth in the R&D Plan; 
 (c) prepare and maintain, or cause to be prepared and maintained, complete and accurate
written records, accounts, notes and reports in good scientific manner and in sufficient detail for patent and regulatory purposes, which shall fully and properly reflect all work done, results achieved, Information generated, and inventions made in
whole or in part, by GCLC or such GCLC Affiliates; and 

  
 16 

 (d) upon the reasonable request of Artiva, make such records available to Artiva for
inspection or copying. 
 4.4 Reports. GCLC shall regularly inform Artiva, through the JSC or directly, of the progress and results of
R&D Program activities conducted by or on behalf of GCLC or GCLC Affiliates. Without limiting the generality of the foregoing, and unless otherwise agreed, GCLC shall provide Artiva written reports of the R&D Program activities performed by
or on behalf of GCLC or GCLC Affiliates and all data, results and other Information generated by or on behalf of GCLC or GCLC Affiliates in the performance of R&D Program activities (“R&D Program Results”)
reasonably in advance of each regularly-scheduled meeting of the JSC. 
 4.5 Materials Transfer. In furtherance of R&D Program
activities, each Party may provide to the other Party chemical compounds or biological materials Controlled by the supplying Party (collectively, the “Materials”) for use by the other Party in conducting the R&D
Program activities for which such other Party is responsible. Except as otherwise expressly provided under this Agreement, all such Materials delivered to the other Party will remain the sole property of the supplying Party, will be used only in
accordance with the R&D Plan and the terms and conditions of this Agreement, will not be used or delivered to or for the benefit of any Third Party without the prior written consent of the supplying Party, and will be used in compliance with all
applicable Laws. The Materials supplied under this Agreement must be used with prudence and appropriate caution in any experimental work because not all of their characteristics may be known. Except as expressly set forth in this Agreement, THE
MATERIALS ARE PROVIDED “AS IS” AND WITHOUT ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR ANY PARTICULAR PURPOSE OR ANY WARRANTY THAT THE USE OF
THE MATERIALS WILL NOT INFRINGE OR VIOLATE ANY PATENT OR OTHER PROPRIETARY RIGHTS OF ANY THIRD PARTY. 
 4.6 Use of Affiliates. GCLC
may perform any R&D Program activity through any GCLC Affiliate; provided, in each case, that: (i) such GCLC Affiliate is bound by written agreement to comply with all applicable terms and conditions of this Agreement to the same
extent as GCLC; (ii) GCLC shall remain fully responsible for the performance of such obligations by such Affiliate and for the compliance of such Affiliate with the terms and conditions of this Agreement; and (iii) any failure of such GCLC
Affiliate to comply with the terms and conditions of this Agreement shall be deemed a breach of this Agreement by GCLC. 
 4.7 Option
Candidate Nomination. As part of the R&D Program, the Parties shall, through the JSC, review the status of Selected Products and assess Information with respect to Selected Products so that the JSC may determine whether any Selected Product
nominated by GCLC as a potential Option Candidate meets the Option Candidate Criteria. When the JSC determines that a Selected Product qualifies as an Option Candidate, the provisions of Section 5 shall apply to such Option Candidate. 

  
 17 

	5.	 OPTION GRANT 

5.1 Grant of Option. Subject to the terms and conditions of this Agreement, with respect to each Option Candidate, GCLC hereby grants to
Artiva, during the applicable Option Exercise Period, a fully paid-up and exclusive option to obtain an exclusive (even as to GCLC), royalty-bearing license, with the
right to sublicense through multiple tiers, under the Selected Product Technology with respect to such Option Candidate, to research, develop, make, have made, use, offer for sale, sell and import such Option Candidate in the Field in the Territory
(each, an “Option”, and collectively, the “Options”). 
 5.2 Option
Candidate Data Package. 
 (a) Delivery. With respect to each Option Candidate, at such time the JSC determines that a
Selected Product qualifies as an Option Candidate, GCLC shall promptly present such Option Candidate to Artiva for its consideration and provide to Artiva all material Information generated by or on behalf of GCLC with respect to such Option
Candidate (“Option Candidate Data Package”), which shall include all research and pre-clinical studies performed with respect to such Option Candidate. GCLC shall make qualified
GCLC representatives reasonably available to Artiva (at a JSC meeting or otherwise) for discussion of such Option Candidate Data Package. The Option Candidate Data Package shall be subject to review by Artiva to determine whether or not such Option
Candidate Data Package is complete with respect to the activities outlined and agreed upon in the R&D Plan and that the Option Candidate meets the Option Candidate Criteria. If Artiva in good faith determines that such Option Candidate Data
Package is not complete, Artiva shall identify the Information not included in such Option Candidate Data Package that is necessary to make such Option Candidate Data Package complete, and GCLC shall promptly make available such Information to
Artiva, which shall then be considered part of the Option Candidate Data Package. Artiva shall make its request, if any, for such additional Information within [***] days after the delivery of the applicable Option Candidate Data Package, and GCLC
shall provide such additional Information to Artiva no later than [***] days after Artiva’s request. 
 (b) Accuracy of Option
Candidate Data Package. As of the date of delivery of each Option Candidate Data Package or the date on which Artiva has received all Information requested pursuant to Section 5.2(a), whichever is later (the “Delivery
Date”), GCLC represents and warrants that the Information included in such Option Candidate Data Package is true, complete and correct. 

5.3 Exercise of Option. Artiva may, in its sole discretion, exercise the Option with respect to each Option Candidate (the
“Option Exercise”) at any time during the applicable Option Exercise Period upon delivery of written notice of exercise of such Option to GCLC (the “Exercise Notice”). Upon exercise of an
Option for an Option Candidate in accordance with this Section 5.3, such Option Candidate shall be deemed an “Exercised Selected Product.” GCLC hereby grants to Artiva an exclusive (even as to GCLC), royalty-bearing license, with the right to sublicense through multiple tiers, under the Selected Product Technology with respect to the Exercised Selected Product, to research, develop, make, have made, use, offer
for sale, sell and import such Exercised Selected Product in the Field in the Territory (each, a “Selected Product 

  
 18 

 License”), which Selected Product license shall automatically be
effective upon exercise of the Option for such Exercised Selected Product. The Parties shall negotiate and enter into a license agreement with respect to such Exercised Selected Product and Selected Product License in accordance with the procedures
set forth in Section 5.4 (each, a “Selected Product License Agreement”); provided that Artiva shall not practice the Selected Product License with respect to such Exercised Selected Product until the
Parties have reached agreement on the economic terms of such Selected Product License pursuant to Section 5.4(b). 
 5.4 Selected
Product License Agreement. 
 (a) Terms Other than Economic Terms. The terms of each Selected Product License Agreement (other
than the economic terms, which shall be determined in accordance with Section 5.4(b)) shall be as mutually agreed by the Parties in good faith within [***] days of the Effective Date (as may be modified or added to by written
agreement of the Parties). 
 (b) Economic Terms. The economic terms of the Selected Product License Agreement for AB-101 shall be as set forth in Exhibit 5.4(b). Following the Delivery Date of the Option Candidate Data Package for an Option Candidate other than
AB-101, the Parties shall negotiate in good faith to determine the amount of upfront payments (if applicable), development milestones payments, sales milestone payments and royalty payments to be reflected in
the Selected Product License Agreement for such Option Candidate if Option Exercise occurs, where the specific amounts shall reflect [***]. If no agreement on such economic terms is reached by the time of the Option Exercise with respect to such
Option Candidate, unless the Parties agree otherwise, then the Parties will submit the dispute for resolution pursuant to Section 13.5 and will enter into a Selected Product License Agreement containing terms determined pursuant to such dispute
resolution (as may be modified or added to by written agreement of the Parties). 
 (c) Consideration of Rights in Additional
Countries. On an Exercised Selected Product-by-Exercised Selected Product basis, Artiva shall have the right to request, and GCLC shall consider in good faith,
inclusion of Australia, New Zealand and/or specific countries in Asia in the Territory for a given Exercised Selected Product. In addition, if it would benefit the contemplated development program for an Exercised Selected Product for development
activities to be conducted by or on behalf of Artiva in specific countries in Asia, Australia and New Zealand, Artiva and GCLC will discuss in good faith the possibility of a co-development collaboration for
such Exercised Selected Product. The Selected Product License Agreement for such Exercised Selected Product would reflect the terms of any agreement by the Parties with respect to such matter. 

  
 19 

 (d) Existing Third Party Agreements. As of the Effective Date, GCLC is a party to
agreements with the following Third Parties that relate to NK Cells, Licensed Products or Information or Patents related to NK Cells or Licensed Products: [***] (the “Existing Third Party Agreements”). The GCLC Core
Technology does not include any Information or Patents Controlled by GCLC by virtue of rights granted under any such Existing Third Party Agreement. The Parties intend that, at Artiva’s election, Artiva would have rights under each such
Existing Third Party Agreements in the Territory by amending and restating such Existing Third Party Agreements so that they are each separated into two agreements: (A) one agreement for rights in the Territory (a “Territory
Third Party Agreement”), which would be assigned by GCLC to Artiva; and (B) one agreement for rights outside the Territory, which would be retained by GCLC (a “Retained Third Party Agreement”).
Artiva would be responsible for all obligations to the Third Party under the applicable Territory Third Party Agreement arising after assignment of the Territory Third Party Agreement to Artiva. GCLC would be responsible for all obligations to the
Third Party under the Existing Third Party Agreements arising prior to any separation (including any liability whenever arising for any action or inaction by GCLC thereunder prior to such separation) and for all obligations under the applicable
Retained Third Party Agreement. To the extent the foregoing approach is not possible with respect to an Existing Third Party Agreement, then rights under such Existing Third Party Agreement in the Territory will be granted by GCLC to Artiva under
the Selected Product License, as applicable, and such Existing Third Party Agreement will be deemed a “Territory Sublicense Third Party Agreement” only if Artiva provides GCLC with written notice in which:
(I) Artiva consents to adding Information and Patents under such Existing Third Party Agreement to the definition of Selected Product Technology and such Existing Third Party Agreement to the definition of Territory Sublicense Third Party
Agreement; (ii) Artiva agrees to be responsible for all payments that would be owed under such agreement between GCLC and such Third Party (as disclosed to Artiva) due to GCLC’s granting a sublicense to Artiva or Artiva’s practice of
such sublicense; and (iii) Artiva acknowledges in writing that its sublicense is subject to the applicable terms and conditions of such Existing Third Party Agreement. 

(e) Other Third Party Licenses. Each Party shall promptly notify the other Party if it becomes aware of any intellectual property rights
of any Third Party that relate specifically to any Exercised Selected Product or other Selected Product or its manufacture or use. To the extent possible, Artiva shall have the right to negotiate and obtain a license from such Third Party in the
Territory, and GCLC shall have the right to negotiate and obtain a license from such Third Party outside the Territory. If GCLC Controls Patents or other intellectual property rights of any Third Party that relate specifically to an Exercised
Selected Product or its manufacture or use in the Territory (other than pursuant to an Existing Third Party Agreement as provided in Section 5.4(d)), GCLC shall notify Artiva in writing of such intellectual property rights, including a
description thereof and any payments that GCLC is obligated to pay in connection with the Territory or the grant, maintenance or exercise of the sublicense to Artiva in the Territory. Such agreement between GCLC and such Third Party shall be deemed
a Territory Sublicense Third Party Agreement, and such intellectual property rights will be sublicensed to Artiva only if Artiva provides GCLC with written notice in which: (i) Artiva consents to adding such intellectual property rights to the
definition of Selected Product Technology and such agreement between 

  
 20 

 GCLC and such Third Party to the definition of Territory Sublicense Third Party Agreement; (ii) Artiva
agrees to be responsible for all payments that would be owed under such agreement between GCLC and such Third Party (as disclosed to Artiva) due to GCLC’s granting a sublicense to Artiva or Artiva’s practice of such sublicense; and
(iii) Artiva acknowledges in writing that its sublicense is subject to the applicable terms and conditions of such agreement between GCLC and such Third Party. 

5.5 Negative Covenant. With respect to any Selected Product, after the Effective Date and during the Term, unless such Selected Product
is deemed a Retained Selected Product pursuant to Section 5.7, GCLC hereby covenants not to practice, and not to grant any of its Affiliates or any Third Party a license to practice or otherwise permit or cause any of its Affiliates or any
Third Party to practice, any Selected Product Technology to research, develop, make, have made, use, offer for sale, sell and import such Selected Product in the Field in the Territory. 

5.6 Co-Development Option. With respect to each Option Candidate, at any time
prior to the expiration of the applicable Option Exercise Period, Artiva may, in its sole discretion, as an alternative to exercising the Option for such Option Candidate, elect to engage with GCLC in discussions to enter into a co-development arrangement for such Option Candidate, for which GCLC shall engage and negotiate with Artiva in good faith (in which case the Option Exercise Period may be extended while the Parties are continuing to
negotiate such arrangement in good faith). 
 5.7 Effect of Non-Exercise of Option;
Reversion of Rights. If upon the expiration of the applicable Option Exercise Period for an Option Candidate, Artiva has not given the Exercise Notice with respect to such Option Candidate, and the Parties are not engaged in negotiating a co-development agreement pursuant to Section 5.6 with respect thereto (the “Option Termination Event”, and such Option Candidate, a “Retained Selected
Product”), then effective upon such Option Termination Event: 
 (a) the Option with respect to such Option Candidate
shall automatically terminate; and 
 (b) subject to the terms and conditions of this Agreement, GCLC shall have the exclusive right
to continue development of such Retained Selected Product, by itself or together with a Third Party, at GCLC’s sole and absolute discretion and, at GCLC’s election, the exclusive right, with the right to sublicense, under the GCLC Core
Technology to research, develop, make, have made, use, offer for sale, sell and import such Retained Selected Product in the Field in the Territory would revert to GCLC (but, for the avoidance of doubt, such reversion shall have no effect on the
Core License as to all Licensed Products other than such Retained Selected Product). 

  
 21 

	6.	 COMPENSATION 

6.1 Core License Royalty Payments. 

(a) Core IP Royalty Rates. Artiva shall pay to GCLC a royalty equal to [***] on Net Sales of each Licensed Product,
including each Exercised Selected Product, the manufacture, use or sale of which is claimed by or uses any GCLC Core Technology, on a country-by-country and Licensed Product-by-Licensed Product basis during the Core IP Royalty Term, subject to the applicable adjustments in accordance with Section 6.1(e) below (the
“Core IP Royalties”). 
 (b) Core IP Royalty Term. Royalties payable under
Section 6.1(a) shall be payable on a Licensed Product-by-Licensed Product and
country-by-country basis in the Territory during the period commencing on the First Commercial Sale of such Licensed Product in such country in the Territory and
continuing until the later of (i) expiration of the last-to-expire Valid Claim of the GCLC Core Patents in the country of sale claiming such Licensed Product or the
manufacture or use of such Licensed Product; (ii) expiration of any Regulatory Exclusivity for such Licensed Product in such country; and (iii) the tenth (10th) anniversary of the First
Commercial Sale of such Licensed Product in such country (the “Core IP Royalty Term”). Following expiration of the Core IP Royalty Term for any Licensed Product in a given country, no further Core IP Royalties shall be
payable in respect of GCLC Core Technology for such Licensed Product in such country, and the Core License granted to Artiva under Section 2.1 with respect to such Licensed Product in such country shall automatically become fully paid-up, perpetual and royalty-free and shall survive any expiration or termination of this Agreement. 

(c) Royalty Reports and Payments. Within [***] days following the end of each calendar quarter following the First Commercial
Sale of a Licensed Product upon which Core IP Royalties are payable anywhere in the Territory, Artiva shall provide GCLC with a report containing the following information for the applicable calendar quarter, on a Licensed Product-by-Licensed Product and country-by-country basis: (i) Net Sales of such Licensed
Product in such country; (ii) the basis for any adjustments to royalties due to GCLC on account of Net Sales of such Licensed Product in such country; (iii) a calculation of the royalty payment due to GCLC on account of Net Sales of such
Licensed Product in such country; and (iv) the exchange rate used in calculating any of the foregoing. 
 (d) Existing Third Party
Payment Obligations. GCLC shall be responsible for any payments to any Affiliates or Third Parties for Patents or Information licensed or acquired by GCLC prior to the Effective Date, which are included in the GCLC Core Technology. 

(e) Royalty Adjustments. Core IP Royalties shall be subject to adjustment as a result of the events set forth below. 

(i) No Valid Claim. During any part of the Core IP Royalty Term for a Licensed Product in which there is no Valid Claim of the
GCLC Core Patents in the country of sale claiming such Licensed Product or the manufacture, use or sale of such Licensed Product in such country, the Core IP Royalties shall be reduced by [***]. 

(ii) Third Party Royalty Credit. If Artiva or any of its Affiliates or Sublicensees obtains a license or sublicense from any
Third Party under any intellectual property that is necessary in order to manufacture, use, sell, offer for sale or import a Licensed Product in the Territory (including any license by a Third Party to Artiva or sublicense by GCLC to Artiva
described in Section 5.4(e), but excluding any license or sublicense to Artiva under an Existing 

  
 22 

 Third Party Agreement as provided in Section 5.4(d)) (each a “Third Party
License”), and GCLC agrees that such Third Party License is necessary to manufacture, use, sell, offer for sale or import such Licensed Product in the Territory, such agreement not to be unreasonably withheld, then Artiva may deduct
[***] of any royalty (or comparable payment based on sales of such Licensed Product) payable by Artiva or its Affiliate or Sublicensee in any calendar quarter in consideration for such Third Party License from the Core IP Royalties that would
otherwise be due in any calendar quarter for such Licensed Product. Any amount paid to such Third Party which is entitled to be deducted under this Section 6.1(e)(ii) but is not deducted as a result of the limitation set forth in
Section 6.1(e)(iv) shall be carried over and applied against Core IP Royalties payable to GCLC in respect of such Licensed Product in such country in subsequent calendar quarters until the full deduction is taken. In no event may Artiva credit
payments under a Third Party License to reduce the Core IP Royalties with respect to a Licensed Product under this Section 6.1(e)(ii) and also to reduce the royalties payable with respect to the same Licensed Product that is an Exercised
Selected Product under a Selected Product License Agreement. 
 (iii) Biosimilar Reduction. If a Biosimilar Product to a
Licensed Product is sold in any country in the Territory during the Core IP Royalty Term for such Licensed Product and country, the Core IP Royalties payable with respect to such Licensed Product in such country will be reduced by [***] for the
remainder of such Core IP Royalty Term. 
 (iv) Limitation. The total deductions under Sections 6.1(e)(ii) and (iii)
shall not reduce the Core IP Royalties payable to GCLC under Section 6.1 (as reduced under Section 6.1(e)(i), if applicable) with respect to a Licensed Product in a given country in any calendar quarter by more than [***]. In no event will
the Core IP Royalties be reduced for any reason whatsoever other than as provided in this Section 6.1(e). 
 6.2 Payment Method;
Currency. All payments due under this Agreement to GCLC shall be made by bank wire transfer in immediately available funds to an account designated by GCLC. All payments hereunder shall be made in Dollars. When conversion of payments from any
currency other than Dollars is required, such conversion shall be at an exchange rate equal to the weighted average of the rates of exchange for the currency of the country from which such payments are payable as published by The Wall Street
Journal, Western U.S. Edition, during the calendar quarter in which the applicable sales were made. 
 6.3 Records;
Inspection. Artiva shall, and shall cause its Affiliates and Sublicensees to, keep complete, true and accurate books of account and records for the purpose of determining the payments to be made under this Agreement. Such books and records shall
be kept for [***] years following the end of the calendar year to which they pertain. Such records shall be open for inspection during such period by independent accountants, solely for the purpose of verifying payment statements hereunder for a
period covering not more than [***] months prior to the date of request; provided that no period shall be subject to inspection under this section more than once. Such inspections shall be made no more than once each calendar year, on
reasonable notice during normal business hours. The independent accountants will execute a reasonable written confidentiality agreement with Artiva and will disclose to GCLC only such information as is reasonably necessary to provide GCLC with
information regarding any actual or potential discrepancies between amounts reported and actually paid and amounts payable under this 

  
 23 

 Agreement. The auditor will send a copy of the report to Artiva at the same time it is sent to GCLC. The
report sent to both Parties will include the methodology and calculations used to determine the results. Any unpaid amounts that are discovered shall be paid promptly by Artiva. Inspections conducted under this Section 6.3 shall be at the
expense of GCLC, unless the inspection discloses an underpayment by Artiva of [***] or more of the amount due for any period covered by the inspection, whereupon all costs relating to the inspection for such period shall be paid promptly by Artiva.
If the inspection discloses an overpayment by Artiva, then Artiva will deduct the amount of such overpayment from amounts otherwise owed to GCLC under this Agreement, unless no further payments are due hereunder, in which case the amount of such
overpayment shall be refunded by GCLC to Artiva. 
 6.4 Income Tax Withholding. Except as otherwise provided herein, GCLC will
pay any and all taxes levied on account of any payments made to it under this Agreement. GCLC shall be responsible for any transfer, documentary, sales use, stamp, registration, value added or other similar tax (“Transfer Tax”) that
is imposed with respect to the payments or the related transfer of rights or other property pursuant to the terms of this Agreement. If any taxes are required to be withheld by Artiva from any payment made to GCLC under this Agreement
(“Withholding Taxes”), Artiva shall (a) deduct such Withholding Taxes from the payment made to GCLC, (b) timely pay the Withholding Taxes to the proper taxing authority, and (c) send proof of payment to GCLC and
certify its receipt by the taxing authority within [***] days following such payment and all such Withholding Taxes shall be treated for all purposes under this Agreement as having been paid to GCLC. To extent Artiva fails to withhold
Withholding Taxes from, or apply and pay Transfer Taxes with respect to, any payment to GCLC and it is determined that Artiva should have withheld Withholding Taxes or applied and paid Transfer Taxes, GCLC agrees to indemnify and/or reimburse Artiva
for any Withholding Taxes or Transfer Taxes, along with penalties and interest as applicable. 
 6.5 Tax Documentation.
GCLC has provided a properly completed and duly executed IRS Form W-8BEN-E to Artiva. Prior to the receipt of any payment under this Agreement, GCLC (and any other
recipient of payments by Artiva under this Agreement) shall, to the extent it is legally permitted to, provide to Artiva, at the time or times reasonably requested by Artiva or as required by applicable Law, such properly completed and duly executed
IRS Forms W-8 or W-9 claiming the benefits of an applicable tax treaty in the case of IRS Form
W-8BEN-E. Such tax forms will, if applicable and legally permissible, claim the benefits of an applicable tax treaty to permit payments made under this Agreement to be
made without, or at a reduced rate of, withholding for taxes. 
  

	7.	 DEVELOPMENT 

7.1 Responsibilities. As between the Parties, Artiva (itself and with its Affiliates and Sublicensees) shall have sole right and
responsibility, and ultimate decision-making authority, at its sole cost and expense, for conducting or having conducted development activities (including preclinical toxicology studies), regulatory activities (including, without limitation, filing
for and obtaining Regulatory Approval, as applicable), manufacturing activities and commercialization activities in the Field in the Territory with respect to any Exercised Selected Products and any other Licensed Product that Artiva elects to
develop, in accordance with the terms and conditions 

  
 24 

 of this Agreement. Artiva shall conduct (and cause its Affiliates and Sublicensees to conduct) all such
activities in compliance in all material respects with all applicable Laws. As between the Parties, Artiva (or its Affiliate or Sublicensee) shall hold legal title to all Regulatory Materials with respect to Exercised Selected Products and other
Licensed Products developed within the Territory. Promptly following the Effective Date, GCLC shall take and cause to be taken such actions and execute such documents that are requested in writing by Artiva to the extent necessary to transfer to
Artiva all Regulatory Materials (if any) within the GCLC Core Know-How and Selected Product Know-How for Exercised Selected Products. 

7.2 Development Plans. 

(a) Development Plan. Within [***] days after exercising an Option with respect to a particular Option Candidate, Artiva shall prepare
and deliver to the JDC for review and discussion an outline of the development, regulatory and manufacturing activities to be conducted by Artiva with respect to the Exercised Selected Product (as amended, the “Development
Plan”). GCLC acknowledges and agrees that Artiva shall have the right to amend the Development Plan at any time in its sole discretion. 

7.3 Development Records and Reports. Artiva shall maintain complete and accurate customary records (in the form of technical notebooks
or electronic files where appropriate) of all development activities conducted by it or its Affiliates or Sublicensees, as applicable, under this Agreement and all Information resulting from such work. Such records, including any electronic files
where such Information may also be contained, shall fully and properly reflect all work done and results achieved in the performance of the development activities in sufficient detail and in good scientific manner appropriate for applicable patent
and regulatory purposes. Upon the expiry of each consecutive [***] period during the Term until First Commercial Sale of a Licensed Product, Artiva shall provide GCLC (through the JDC) with an update of development activities conducted by Artiva or
its Affiliates or Sublicensees, as applicable, with respect to Exercised Selected Products. Any information or report provided by Artiva to GCLC pursuant to this Section 7.3 shall be Artiva’s Confidential Information and subject to the
provisions of Article 9.

	12.	 INDEMNIFICATION AND LIMITATION OF LIABILITY 

12.1 Indemnification. 

(a) Indemnification by Artiva. Artiva shall defend, indemnify, and hold GCLC and its Affiliates and their respective officers,
directors, employees, and agents (the “GCLC Indemnitees”) harmless from and against any and all damages or other amounts payable by such GCLC Indemnitees, including any reasonable attorneys’ fees, taxes (including penalties and
interest), and costs of litigation incurred by, such GCLC Indemnitees, to the extent resulting from claims, suits, proceedings, or causes of action brought by any Third Party (“Claims”) against such GCLC Indemnitees that arise from
or are based on: (i) the development, manufacture or commercialization of any Licensed Product in the Territory, or performance of the CMC Activities, by or on behalf of Artiva or its Affiliates or Sublicensees (excluding in all cases GCLC or
its Affiliates); (ii) the breach of any of Artiva’s obligations under this Agreement, including Artiva’s representations, warranties or covenants set forth herein; or (iii) the willful misconduct or negligent acts of Artiva or
any of its Affiliates or any of its or their respective officers, directors, employees or agents. The foregoing indemnity obligation shall not apply to the extent to the extent that any of the Claims arises from, is based on, or results from any
activity described in Section 12.1(b)(i), (ii) or (iii) for which GCLC is obligated to indemnify the Artiva Indemnitees under Section 12.1(b). 

  
 37 

 (b) Indemnification by GCLC. GCLC shall defend, indemnify, and hold Artiva and
its Affiliates and their respective officers, directors, employees, and agents (the “Artiva Indemnitees”) harmless from and against any and all damages or other amounts payable by such GCLC Indemnitees, including any
reasonable attorneys’ fees, taxes (including penalties and interest), and costs of litigation incurred by such Artiva Indemnitees, to the extent resulting from Claims against such Artiva Indemnitees that arise from or are based on: (i) the
development, manufacture or commercialization of any Licensed Product, or performance of the CMC Activities, by or on behalf of GCLC or its Affiliates, licensees or sublicensees (other than Artiva and its Affiliates and Sublicensees); (ii) the
breach of any of GCLC’s obligations under this Agreement, including of GCLC’s representations, warranties or covenants set forth herein; or (iii) the willful misconduct or negligent acts of GCLC or any of its Affiliates or any of its
or their respective officers, directors, employees or agents. The foregoing indemnity obligation shall not apply to the extent to the extent that any of the Claims arises from, is based on, or results from any activity set forth in
Section 12.1(a)(i), (ii) or (iii) for which Artiva is obligated to indemnify the GCLC Indemnitees under Section 12.1(a). 

(c) Indemnification Procedures. The Party seeking indemnification (individually, the “Indemnified
Party”), shall promptly notify the other Party (the “Indemnifying Party”) in writing of the Claim. Such Claim for indemnity shall indicate the nature of the Claim and the basis therefor. Promptly after
a Claim is made for which the Indemnified Party seeks indemnity, the Indemnified Party shall permit the Indemnifying Party, at its option and expense, to assume the complete defense of such Claim, provided that (i) the Indemnified Party
will have the right to participate in the defense of any such Claim at its own cost and expense, (ii) the Indemnifying Party will conduct the defense of any such Claim with due regard for the business interests and potential related liabilities
of the Indemnified Party, and (iii) the Indemnifying Party will not agree to any settlement that would admit liability on the part of the Indemnified Party or involve relief other than payment of money, without the approval of the Indemnified
Party, not to be unreasonably withheld; and provided, further, that if it is reasonably likely that the Parties may have conflicting interests or if it is otherwise not advisable under applicable legal and ethical requirements for the
Indemnifying Party’s defense counsel to represent both Parties, separate independent counsel shall be retained for each Party at its own expense. The Indemnifying Party will not, in defense of any such Claim, except with the consent of the
Indemnified Party, consent to the entry of any judgment or enter into any settlement which does not include, as an unconditional term thereof, the giving by the claimant or plaintiff to the Indemnified Party of a release from all liability in
respect thereof. After notice to the Indemnified Party of the Indemnifying Party’s election to assume the defense of such Claim, the Indemnifying Party shall be liable to the Indemnified Party for such legal or other expenses subsequently
incurred by the Indemnified Party in connection with the defense thereof at the request of the Indemnifying Party. As to those Claims with respect to which the Indemnifying Party does not elect to assume control of the defense, the Indemnified Party
will afford the Indemnifying Party an opportunity to participate in such defense at the Indemnifying Party’s own cost and expense, and will not settle or otherwise dispose of any of the same without the consent of the Indemnifying Party. 

12.2 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR
INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 12.2 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE
INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 12.1 OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE 9. 

  
 38 

 12.3 Insurance. Each Party shall procure and maintain insurance, including
product liability insurance, with respect to its activities hereunder and which is consistent with normal business practices of prudent companies similarly situated at all times during which any Licensed Product is being clinically tested in human
subjects or commercially distributed or sold. Each Party shall provide the other Party with evidence of such insurance upon request and shall provide the other Party with written notice at least [***] days prior to the cancellation, non-renewal or material changes in such insurance. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under
this Article 12. 
  

	13.	 DISPUTE RESOLUTION 

13.1 Disputes. The Parties recognize that disputes as to certain matters arising under or relating to this Agreement or either
Party’s rights or obligations hereunder may from time to time arise. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation
and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Article 13 to resolve any controversy or claim arising out of, relating to or in connection with any provision of this
Agreement, if and when a dispute arises under this Agreement. 
 13.2 Internal Resolution. With respect to all disputes arising
between the Parties under this Agreement, including any alleged breach under this Agreement or any issue relating to the interpretation or application of this Agreement, if the Parties are unable to resolve such dispute within [***] days after such
dispute is first notified by either Party in writing to the other, the Parties shall refer such dispute to the Executive Officers (or their designees) for attempted resolution by good faith negotiations within [***] days after such notice is
received, including at least one (1) in person meeting of the Executive Officers within [***] days after such notice referring the dispute to the Executive Officers is received. 

13.3 Binding Arbitration. If the Executive Officers of the Parties are not able to resolve such disputed matter within [***] days and
either Party wishes to pursue the matter, each such dispute, controversy or claim, subject to Section 13.4, shall be finally resolved by binding arbitration administered by the International Chamber of Commerce (“ICC”) pursuant
to its Dispute Resolution Rules then in effect, and judgment on the arbitration award may be entered in any court having jurisdiction thereof. The Parties agree that: 

(a) The arbitration shall be conducted by a panel of three (3) persons experienced in the pharmaceutical business. Within [***]
days after initiation of arbitration, each Party shall select one (1) person to act as arbitrator and the two (2) Party-selected arbitrators shall select a third arbitrator within [***] days of their appointment. If the arbitrators
selected by the Parties are unable or fail to agree upon the third arbitrator, the third arbitrator shall be appointed by the ICC. The place of arbitration shall be New York, New York, and all proceedings and communications shall be in English. 

  
 39 

 (b) Either Party may apply to the arbitrators for interim injunctive relief until the
arbitration award is rendered or the controversy is otherwise resolved. Either Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the
rights or property of that Party pending the arbitration award. The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damage. Each Party shall bear its own costs and
expenses and attorneys’ fees and an equal share of the arbitrators’ fees and any administrative fees of arbitration, unless the arbitrators determine that a Party has incurred unreasonable expense due to vexatious or bad faith position
taken by the other Party, in which event, the arbitrators may make an award of all or any portion of such expenses so incurred. 
 (c)
Reasons for the arbitrators’ decisions should be complete and explicit, including reasonable determinations of law and fact. The written reasons should also include the basis for any damages awarded and a statement of how the damages were
calculated. Such a written decision shall be rendered by the arbitrators following a full comprehensive hearing, no later than [***] months following the selection of the arbitrators under Section 13.3(a). 

(d) Except to the extent necessary to confirm an award or as may be required by applicable Laws, neither Party nor any arbitrator may
disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute,
controversy or claim would be barred by the applicable statute of limitations. 
 13.4 Excluded Disputes. Notwithstanding
Section 13.3, any dispute, controversy or claim relating to (a) the scope, validity, enforceability or infringement of any Patent, trademark or copyright or (b) any antitrust, anti-monopoly or competition law or regulation, whether or
not statutory shall be submitted to a court of competent jurisdiction. 
 13.5 License Terms Determination. 

(a) If the Parties fail to agree on all economic terms of a Selected Product License Agreement for an Option Candidate pursuant to
Section 5.4(b) before Artiva delivers an Exercise Notice with respect thereto, then unless otherwise agreed in writing by the Parties (including any agreement by the Parties to continue negotiation of such terms) the unresolved terms shall be
finally settled by an impartial and independent Third Party acting as expert, and not as an arbitrator (the “Expert”). 

(b) The Expert shall be an expert in [***]. Before accepting appointment, the Expert shall disclose to the Parties any circumstances
that might give rise to a reasonable basis for questioning the Expert’s impartiality or independence, or confirm in writing that no such circumstances exist. 

  
 40 

 (c) Within [***] Business Days following the selection of the Expert, each Party
shall prepare and submit to the Expert and the other Party a written report setting forth its position with respect to the unresolved terms of the license. Each Party shall have [***] Business Days from receipt of the other Party’s submission

 (d) The
Expert shall [***]. No later than [***] days after the designation of the Expert, the Expert shall make a determination, which will be made by [***]. The Expert shall provide the Parties with a written statement setting forth the basis of the
