attorneys’ fees (“Losses”), to which any such GCLC Indemnitee may become subject as a result of any suit, claim, demand, action or other proceeding by any third party (in each case, a
“Third Party Claim”), to the extent such Losses arise out of: (a) the material breach by Artiva of any representation, warranty,
covenant or agreement made by it under this Agreement; (b) the gross negligence or willful misconduct of any Artiva Indemnitee (as defined below); (c) the development, manufacture, use, handling, storage, sale or other disposition of any Artiva
Selected Product or the exploitation of Work Product by or on behalf of Artiva or (d) the use of Materials by GCLC in connection with the Services in accordance with the Protocol and Artiva’s instructions, or with respect to any deficiency
or defect in Materials; except, in each case, to the extent such Losses result from the material breach by GCLC of any representation, warranty, covenant or agreement made by it under this Agreement or the negligence or willful misconduct of any
GCLC Indemnitee. 
 9.2 GCLC Indemnification. GCLC hereby agrees to save, defend, indemnify and hold harmless Artiva and its
officers, directors, employees, consultants, contractors and agents (“Artiva Indemnitees”) from and against any and all Losses to which any such Artiva Indemnitee may
become subject as a result of any Third Party Claim to the extent such Losses arise out of the material breach by GCLC of any representation, warranty, covenant or agreement made by it under this Agreement or the gross negligence or willful
misconduct of any GCLC Indemnitee; except, in each case, to the extent such Losses result from the material breach by Artiva of any representation, warranty, covenant or agreement made by it under this Agreement or the gross negligence or willful
misconduct of any Artiva Indemnitee. 

  
 [Page 10 of 15] 

 9.3 Indemnification Procedures. A party claiming indemnification under this
Article 9 (the “Indemnitee”) shall promptly notify the other party (the “Indemnitor”) in writing of any action, claim or other matter in respect
of which the Indemnitee or any of its directors, officers, employees and agents intend to claim such indemnification; provided, however, the failure to provide such notice within a reasonable period of time shall not relieve the
Indemnitor ofany of its obligations hereunder except to the extent the Indemnitor is materially prejudiced by such failure. The Indemnitor shall not enter into any settlement that would adversely affect the Indemnitee’s rights hereunder or
impose any obligations on the Indemnitee in addition to those set forth herein without the Indemnitee’s prior written consent. The Indemnitee may not settle any Third Party Claim without the prior written consent of the Indemnitor, which shall
not be unreasonably withheld, conditioned, or delayed. The Indemnitee and its directors, officers, employees and agents shall cooperate fully with the Indemnitor and its legal representatives in the investigation and defense of any action, claim or
other matter covered by the indemnification obligations of this Section 9.3. The Indemnitee may participate in such defense by counsel of its own selection and at its own expense. 

9.4 Conflict of Interest. Notwithstanding anything to the contrary contained in this Agreement, if a conflict of interest exists
between the parties with respect to a Third Party Claim for which indemnification is sought by one or both parties, or if the assumption and conduct of the defense by the Indemnitor would adversely affect the Indemnitee in any manner or prejudice
its ability to conduct a successful defense, then the Indemnitee may be separately represented with respect to such Third Party Claim by legal counsel reasonably acceptable to the Indemnitor and at the Indemnitor’s expense. 

9.5 Insurance. GCLC, at its own expense, shall secure and maintain in full force and effect throughout the term of this Agreement
insurance coverage for general, professional and contractual liability (including errors and omissions coverage) in commercially reasonable amounts in light of GCLC’s obligations hereunder with a reputable
A-rated insurance company. In addition, GCLC shall secure and maintain in full force and effect throughout the term of this Agreement workers’ compensation insurance in the amount required by the laws of
any country in which any of GCLC’s employees performing Services hereunder are located. GCLC shall provide a certificate of insurance evidencing the required coverage under this Section 9.5 to Artiva upon request. Notwithstanding, it is
understood that such insurance shall not be construed to create a limit of Artiva’s liability with respect to its indemnification obligation under this Article 9 or any other liability to compensate GCLC under this Agreement. 

10. GENERAL PROVISIONS. 

10.1 No Implied Licenses. No right or license is granted under this Agreement by either party
to the other, either expressly or by implication, except those specifically set forth herein.

Relationship. GCLC’s relationship with Artiva is that of an independent contractor, and nothing in this Agreement should be construed to create a partnership, joint venture, or employer-employee relationship. Each party is not an agent of
thevother party and is not authorized to make any representation, contract, or commitment on behalf of such other party. Each party shall be responsible for all of its tax returns and payments required to be filed with or made to any national, state
or local tax authority with respect to transaction contemplated under this Agreement. 

  
 [Page 11 of 15] 

 10.3 Use of Names. Neither party shall use the other party’s name or the
names of the other party’s employees in any advertising or sales promotional material or in any publication without prior written permission of the other party. However, in its use of the Work Products and/or Arising Intellectual Property with
or towards any third party, Artiva shall clearly indicate that the ownership of any and all intellectual property rights thereof belongs to GCLC if and as required by the Master Agreement and/or Selected Product License Agreement. 

10.4 Successors and Assigns. Neither party may assign this Agreement without the prior written consent of the other party;
provided, however, that Artiva may assign this Agreement without GCLC’s consent in connection with the transfer or sale of all or substantially all of the business of Artiva to which this Agreement relates, whether
by merger, sale of stock, sale of assets or otherwise. Any attempted assignment of this Agreement not in compliance with this Section 10.4 shall be null and void. No assignment shall relieve either party of the performance of any accrued
obligation that such party may then have under this Agreement. This Agreement shall inure to the benefit of and be binding upon each party signatory hereto, its successors and permitted assigns. 

10.5 Dispute Resolution. The parties agree that 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, that is not resolved by mutual written agreement of the parties (a “Claim”), shall, upon the written request of either party to the other party,
be resolved by final and binding arbitration administered by the International Centre for Dispute Resolution (“ICDR”) in accordance with the then-effective provisions of its International Arbitration Rules (the
“Rules”), except to the extent any such Rule conflicts with the express provisions of this Section 10.5. Capitalized terms used but not otherwise defined in this Section 10.5 shall have the meanings provided in the
Rules. The parties agree that: 
 (a) The arbitration shall be conducted by three (3) arbitrators (the
“Arbitrators”), none of whom shall be a current or former employee or director, or a current stockholder, of either party or any of their respective Affiliates. Each party shall appoint one Arbitrator within [***] days after
submission of the Answer to the Notice of Arbitration, and the two-party appointed shall appoint a third Arbitrator, who shall serve as chair of the tribunal, within [***] days after the appointment of the
later-appointed Arbitrator. If any of the Arbitrators are not appointed within the time prescribed above, then the ICDR shall appoint the Arbitrator(s) in accordance with its International Arbitration Rules. 

(b) The arbitration and all associated discovery proceedings and communications shall be conducted in English. The seat of the
arbitration shall be Singapore. The Award rendered by the Arbitrators shall be final, binding and non appealable, and judgment may be entered upon it in any court of competent jurisdiction. The Arbitrators shall have no authority to award punitive
or any other type of damages not measured by a party’s compensatory damage. The Arbitrators will, in rendering their decision, apply the substantive law of the laws of the State of New York, U.S., excluding its conflicts of laws principles.
Each party shall bear its own attorney’s fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the Arbitrators. 

  
 [Page 12 of 15] 

 (c) Notwithstanding the foregoing, nothing contained in this Agreement shall deny
either party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any
ongoing discussions between the parties or any ongoing arbitration proceeding. In addition, either party may apply to the Arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved.
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. 

10.6 Governing Law. Resolution of all disputes, controversies or claims arising out of, relating to or in connection with this
Agreement or the performance, enforcement, breach or termination of this Agreement and any remedies relating thereto, shall be governed by and construed under the substantive laws of the State of New York, U.S., without regard to conflicts of law
rules. 
 10.7 Entire Agreement; Amendment. This Agreement, including its Exhibits (if any) and Work Orders, constitutes the
final, complete and exclusive agreement of the parties with respect to the subject matter hereof and supersedes all prior understandings and agreements relating to its subject matter, except, for the avoidance of doubt, the Master Agreement and the
Selected Product Agreements. This Agreement may not be changed, modified, amended or supplemented except by a written instrument signed by both parties. 

10.8 Non-Waiver. No failure or delay of one of the parties to insist upon strict
performance of any of its rights or powers under this Agreement shall operate as a waiver thereof, nor shall any other single or partial exercise of such right or power preclude any other further exercise of any rights or remedies provided by law.
Any waiver by a party of a particular provision or right shall be in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be executed by an authorized officer of the waiving party. 

10.9 Severability. If any provision of this Agreement is found by a court of competent jurisdiction to be unenforceable, then
such provision shall be construed, to the extent feasible, so as to render the provision enforceable, and if no feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement. The remainder of this
Agreement shall remain in full force and effect, unless the severed provision is essential and material to the rights or benefits received by either party. In such event, the parties shall negotiate, in good faith, and substitute a valid and
enforceable provision or agreement that most nearly implements the parties’ intent in entering into this Agreement. 
 10.10
Notices. Any notice required or permitted to be given under this Agreement must be in writing and delivered either in person, by any method of mail (postage prepaid) requiring return receipt, by overnight courier or by electronic mail, to

RECITALS 

A. The Parties have previously entered into that certain Option and License Agreement, dated as of September 4, 2019 (as may be
amended, the “Option Agreement”), pursuant to which, among other things, GCLC has granted to Artiva an exclusive option to obtain an exclusive license under Selected Product Technology to develop, manufacture and commercialize
Selected Products in the Field in the Territory (each term as defined in the Option Agreement) (the “Option”). 
 B.
Artiva has exercised its Option with respect to the Product in accordance with the terms and conditions of the Option Agreement, and GCLC has granted to Artiva the Selected Product License (as defined in the Option Agreement) as to the Product. 

C. In accordance with Section 5.3 of the Option Agreement, the Parties desire to enter into this Agreement to set forth additional
terms and conditions of the Selected Product License as to the Product. 
 NOW,
THEREFORE, in consideration of the foregoing premises and the mutual promises, covenants and conditions contained in this Agreement, the Parties agree as follows: 

1. DEFINITIONS 
 Capitalized terms used in this Agreement
(other than the headings of the Sections or Articles) have the following meanings set forth in this Article 1, or, if not listed in this Article 1, the meanings as designated in the text of this Agreement. Capitalized terms used in this Agreement
but not otherwise defined herein shall have such meanings ascribed to them in the Option Agreement. 
 1.1 “Combination
Product” means any combination of the Product with one (1) or more other active ingredients, products or services that is not the Product, where such products are sold either as a fixed dose/unit or as separate doses/units in a single
package for a single price. 
 1.2 “Existing Third Party Agreements” means the following Agreements to which GCLC is
a party with the following Third Parties that relate to NK Cells, Licensed Products or Information or Patents related to NK Cells or Licensed Products: [***].

1.4 “Initiation” of a clinical trial means the first dosing of the first subject enrolled in such clinical trial. 

  
 1 

 1.5 “[***]” means [***]. 

1.6 “[***]” means [***]. 

1.7 “[***]” means [***]. 

1.8 “Net Sales” means, with respect to a given period of time, the gross amount invoiced by Artiva and its Affiliates
and Sublicensees (each, a “Selling Party”) to Third Party (other than any Selling Party) purchasers for the sale or distribution of Products in the Territory, less the following deductions and offsets that are actually incurred,
allowed, accrued, paid or taken and are allocated with respect to such sale or distribution: 
 (a) [***];

With respect to (c) above, (i) no deductions will be made for commissions paid to individuals whether they be with independent sales
agencies or regularly employed by Licensee and on its payroll, or for cost of collections, and (ii) if a Product is distributed at a discounted price that is substantially lower than the customary price charged by Licensee, or distributed for non-cash consideration (whether or not at a discount), Net Sales will be calculated based on the non-discounted amount of the Product charged to an independent Third Party
during the same calendar quarter or, in the absence of such sales, on the fair market value of the Product. 
 Sales of Products by a
Selling Party to another Selling Party for resale by such entity to a Third Party (other than a Selling Party) shall not be deemed a sale for purposes of this definition of “Net Sales,” provided that the subsequent resale is
included in the computation of Net Sales. Transfers or dispositions of Products as free promotional samples in commercially reasonable amounts, consistent with prevailing industry standards, and Products used in research, development or regulatory
activities, compassionate use, indigent programs, investigator-initiated trials or on a named patient basis shall be disregarded in determining Net Sales. 

If any discounts or other deductions or rebates are made in connection with sales of a Product that is bundled or sold together with other
products of the Selling Parties, then the discount, deduction or rebate applied to the Product shall not exceed the discount, deduction or rebate applied to any of the other products of the Selling Parties in such arrangement based upon the
respective list prices of the Product and such other products prior to applying the discount, unless Artiva provides evidence reasonably satisfactory to GCLC that such difference is commercially reasonable and does not unfairly prejudice the Product
in favor of such other products. 

  
 2 

 For Products which are sold as Combination Products, the Net Sales for such Combination Products shall be
adjusted by [***]. 
 1.9 “Pivotal Clinical Trial” means a pivotal study in human patients with a defined dose or a

2.2 Sublicensing; Subcontracting. Artiva shall have the right to grant sublicenses of rights granted under the Product License, or
subcontract its activities with respect to any Product, to its Affiliates, contractors and any other Third Party, provided that: (a) Artiva shall remain responsible for the performance or failure to perform by any such Affiliate,
Sublicensee and subcontractor under their respective sublicensed or subcontracted rights or obligations to the same extent as if such activity were performed (or was failed to be performed) by Artiva; and (b) each such sublicense and
subcontract agreement shall be consistent with the terms and conditions of this Agreement. Artiva shall provide GCLC with a copy of any sublicense agreement entered into with a Sublicensee, and any amendment thereto, within [***] days of its
execution (provided that Artiva may redact any confidential information contained therein that is not necessary to disclose to ensure compliance with this Agreement). 

2.3 Reserved Rights. GCLC hereby expressly reserves (a) all rights to practice, and to grant licenses under, the Product Technology
and GCLC’s interest in Additional Joint Inventions and Additional Joint Patents outside the Territory, and (b) the right to conduct research and development to be conducted by GCLC or any GCLC Affiliate as contemplated by this Agreement

advice of its technical personnel as may be reasonably requested by Artiva in connection with such transfer of Product Know-How. 

2.7 Development Option. If GCLC desires to pursue development of a Product in combination with an antigen-specific therapy that Artiva
has determined not to pursue, the Parties shall discuss in good faith and agree on a co-development arrangement for such Product in combination with such antigen-specific therapy in mutually agreed Indications
in the Territory, which shall not overlap with Indications for which Artiva is developing a Product.

 (b) Product Royalty Term. Royalties payable under Section 3.1(a) shall be
payable on a Product-by-Product and country-by-country basis in the Territory during the
period commencing on the First Commercial Sale of such Product in such country in the Territory and continuing until the later of (i) expiration of the
last-to-expire Valid Claim of the Product Patents in the country of sale claiming such Product or the manufacture or use of such Product; (ii) expiration of any
Regulatory Exclusivity for such Product in such country; and (iii) the tenth (10th) anniversary of the First Commercial Sale of such Product in such country (the “Product Royalty Term”). Following expiration of the Product
Royalty Term for any Product in a given country, no further Product Royalties shall be payable in respect of Product Technology for such Product in such country, and the Product License granted to Artiva under Section 2.1 with respect to such
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
Product upon which Product 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 Product-by-Product and country-by-country basis: (i) Net Sales of such Product in such country; (ii) the basis for any
adjustments to royalties due to GCLC on account of Net Sales of such Product in such country; (iii) a calculation of the royalty payment due to GCLC on account of Net Sales of such Product in such country; and (iv) the exchange rate used

or Information licensed or acquired by GCLC prior to the Effective Date, excluding the [***], which are included in the Product Technology. 

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

(i) No Valid Claim. During any part of the Product Royalty Term for a Product in which there is no Valid Claim of either the GCLC Core
Patents or the Product Patents in the country of sale claiming such Product or the manufacture, use or sale of such Product in such country, the Product Royalties shall be reduced by [***], which reduction will be calculated by determining the
portion of total Net Sales of the relevant Product in a calendar quarter that is attributable to the country in which such reduction applies, and determining the total Product Royalties for such Product without reduction, and then reducing by [***]
the applicable portion (based on Net Sales of such Product in such country as a percentage of total Net Sales of such Product) of total Product Royalties attributable to such Product in such country. 

  
 6 

 (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 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) of the Option Agreement, but excluding any license or sublicense to Artiva under an Existing Third Party Agreement as provided in Section 5.4(d) of the Option Agreement) (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 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 Product) payable by Artiva or its Affiliate or Sublicensee in any calendar quarter in consideration for such Third Party License from the Product Royalties that would
otherwise be due in any calendar quarter for such Product. Any amount paid to such Third Party which is entitled to be deducted under this Section 3.1(e)(ii) but is not deducted as a result of the limitation set forth in Section 3.1(e)(iv)
shall be carried over and applied against Product Royalties payable to GCLC in respect of such 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 Product Royalties with respect to a Product under this Section 3.1(e)(ii) and also to reduce the Core IP Royalties payable with respect to the same Product that is a Licensed Product under the Option Agreement. 

(iii) Biosimilar Reduction. If a Biosimilar Product to a Product is sold in any country in the Territory during the Product Royalty
Term for such Product and country, the Product Royalties payable with respect to such Product in such country will be reduced by [***] for the remainder of such Product Royalty Term. 

(iv) Limitation. The total deductions under Sections 3.1(e)(ii) and (iii) shall not reduce the Product Royalties payable to GCLC
under Section 3.1 (as reduced under Section 3.1(e)(i), if applicable) with respect to a Product in a given country in any calendar quarter by more than [***]. In no event will the Product Royalties be reduced for any reason whatsoever
other than as provided in this Section 3.1(e). 
 3.2 Milestone Payments. 

(a) Development Milestone Payments. Artiva shall make the following non-refundable and non-creditable development milestone payments to GCLC within [***] days after the first achievement of each applicable milestone event with respect to a Product by Artiva or its Affiliates or Sublicensees. Each such
milestone payment shall be paid only once during the Term, the first time a Product reaches such milestone event and regardless of the number of times such milestone event is reached for a Product and of the number of subsequent Products reaching
such milestone event. For clarification, the total milestone payments payable hereunder if all milestone events are achieved is [***].

 3.3 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. 
 3.4 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 and inspections with respect to payments on a Product under this Agreement shall be done concurrently with respect to payments on the same Product under the Option Agreement to avoid
duplication. 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 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 3.4 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.

 3.5 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. 
 3.6 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. 
 4. INTELLECTUAL PROPERTY 

4.1 Ownership. All Information, discoveries and inventions (patentable or not) generated, conceived or reduced to practice in the

(a) Product Patents. Artiva shall have the first right, but not the obligation, at Artiva’s expense, to control the preparation,
filing, prosecution (including any interferences, reissue proceedings and reexaminations) and maintenance of the Product Patents in the Territory. Artiva shall keep GCLC reasonably informed of progress with regard to the preparation, filing,
prosecution and maintenance of Product Patents in the Territory, including the countries in the Territory in which it intends to file, maintain or abandon a given Product Patent. Artiva will notify GCLC of all warning letters, conflict proceedings,

written notice to GCLC of such intention (which notice shall, in any event, be given no later than [***] days prior to the next deadline for any action that may be taken with respect to such Product Patent in the Territory with the applicable patent
office), and upon GCLC’s written election provided no later than [***] days after such notice from Artiva, Artiva shall continue prosecution or maintenance of such Product Patent at GCLC’s direction and expense. If GCLC does not provide
such election within [***] days after such notice from Artiva, Artiva may continue prosecution and maintenance of such Product Patent in the Territory or discontinue prosecution and maintenance of such Product Patent in the Territory. GCLC shall
have the sole right, but not the obligation, at GCLC’s expense, to control the preparation, filing, prosecution (including any interferences, reissue proceedings and reexaminations) and maintenance of the Product Patents outside the Territory.
GCLC shall keep Artiva reasonably informed of progress with regard to the preparation, filing, prosecution and maintenance of Product Patents outside the Territory to the extent such activities could affect the Product Patents in the Territory. The

the extent reasonably required to allow Artiva to assume the preparation, filing, prosecution and maintenance in the Territory of the Product Patents in Artiva’s name. Artiva shall cooperate with GCLC, in each case to the extent reasonably
required to allow GCLC to assume the preparation, filing, prosecution and maintenance, of any Patent abandoned by Artiva pursuant to Section 4.2(a). 

4.3 Patent Enforcement. 

(a) Notification. If either Party becomes aware of any existing or threatened infringement of the Product Patents or Additional Joint
Patents, or the filing of a BLA by a Third Party for a product that names a Product as a reference product (or similar filing in a country other than the U.S.), it shall promptly notify the other Party in writing to that effect, and the Parties will
consult with each other regarding any actions to be taken with respect to such infringement. 

  
 11 

 (b) Right to Enforce. Artiva shall have the first right, but shall not be obligated,
to bring and control an infringement action with respect to any Product Patent or Additional Joint Patent in the Territory against any person or entity, at Artiva’s sole cost and expense. If Artiva does not bring such an action with respect to
a Product Patent or Additional Joint Patent in the Territory (or settle or otherwise secure the abatement of such infringement) prior to the earlier of: (i) [***] days following Artiva’s receipt or delivery of the notice under
Section 4.3(a), or (ii) [***] days before the deadline, if any, set forth in the applicable Laws for the filing of such actions, GCLC shall have the right to bring and control any such action, at its own expense and by counsel of its own
choice. The provisions of this Section 4.3(b) are subject to the rights of [***] under the [***]. 
 (c) Cooperation. Each Party
shall cooperate fully with the enforcing Party in such enforcement, at such enforcing Party’s request and expense, including joining such action as a party plaintiff if required by applicable Laws to pursue such action. The enforcing Party
shall keep the other Party regularly informed of the status and progress of such enforcement efforts, shall reasonably consider the other Party’s comments on any such efforts. The non-enforcing Party
shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but such Party shall at all times cooperate fully with the enforcing Party. Neither Party shall have the right to settle any patent
infringement litigation under this Section 4.3 in a manner that diminishes the rights or interests of the other Party without the prior written consent of such other Party, such consent not to be unreasonably withheld or delayed. 

(d) Expenses and Recoveries. The enforcing Party bringing a claim, suit or action under this Section 4.3 shall be solely
responsible for any expenses incurred by such Party as a result of such claim, suit or action. If such Party recovers monetary damages in such claim, suit or action, except as otherwise agreed by the Parties in connection with a cost-sharing
arrangement, such recovery shall be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation, and any remaining amounts shall be shared as follows: [***]. 

(e) Enforcement Outside the Territory. GCLC shall have the sole right, but shall not be obligated, to bring and control an infringement
action with respect to any Product Patent or Additional Joint Patent outside the Territory against any person or entity, at GCLC’s sole cost and expense. GCLC shall keep Artiva reasonably informed of the enforcement of Product Patents or
Additional Joint Patents outside the Territory to the extent such activities could affect the Product Patents or Additional Joint Patents in the Territory.

 4.4 Patent Oppositions and Other Proceedings. 

(a) In the Territory. If a Product Patent or Additional Joint Patent in the Territory becomes the subject of any proceeding commenced by
a Third Party in connection with an opposition, action for declaratory judgment, nullity action, interference or other attack upon the validity, title or enforceability thereof, then Artiva shall have the first right, but not the obligation, to
control such defense at its own expense using counsel of its own choice. If Artiva decides that it does not wish to defend against such action, it shall notify GCLC reasonably in advance of all applicable deadlines, and GCLC shall thereafter have
the right, but not the obligation, to assume defense of such action at its own expense. 
 (b) The Party controlling any defense under
Section 4.4(a) shall permit the non-controlling Party to participate in the proceedings to the extent permissible under applicable Laws and to be represented by its own counsel at the non-controlling Party’s expense. Notwithstanding any of the foregoing, the Party controlling any enforcement action pursuant to Section 4.3 shall also have the sole right to control the response to any
attack on the validity, title, or enforceability of a Patent that is asserted by the alleged infringer(s) as a counterclaim or affirmative defense in such action. Neither Party shall have the right to settle any proceeding under this
Section 4.4 in a manner that diminishes the rights or interests of the other Party without the prior written consent of such other Party, such consent not to be unreasonably withheld or delayed. 

(c) Outside the Territory. GCLC shall have the sole right, but shall not be obligated, to control any opposition, action for declaratory
judgment, nullity action, interference or other attack upon the validity, title or enforceability of any Product Patent or Additional Joint Patent outside the Territory, at GCLC’s own expense using counsel of its own choice. GCLC shall keep
Artiva reasonably informed of any such defense of Product Patents or Additional Joint Patents outside the Territory to the extent such activities could affect the Product Patents or Additional Joint Patents in the Territory.

4.6 Infringement of Third Party Rights. If any Product used or sold by Artiva or its Affiliates or Sublicensees becomes the subject of a
Third Party’s claim or assertion of infringement of a Patent, each Party shall promptly notify the other Party. Neither Party shall have the right to settle any patent infringement litigation under this Section 4.6 in a manner that
diminishes the rights or interests of the other Party without the written consent of such other Party (which shall not be unreasonably withheld).

 5.2 Termination for Material Breach. Each Party shall have the right to terminate
this Agreement in its entirety immediately upon written notice to the other Party if the other Party materially breaches its obligations under this Agreement and, after receiving written notice identifying such material breach in reasonable detail,
fails to cure such material breach within sixty (60) days from the date of such notice (or within thirty (30) days from the date of such notice in the event such material breach is solely based on the breaching Party’s failure to pay
any amounts due hereunder); provided, however, in the case of a breach or violation that cannot be cured within such sixty (60) day period, the non-breaching Party may terminate this Agreement
following such sixty (60) day period only if the breaching Party shall have failed to commence substantial remedial actions within such sixty (60) day period and to use reasonable efforts to pursue the same. Any right to terminate under
this Section 5.2 shall be stayed and the cure period tolled in the event that, during any cure period, the breaching Party shall have initiated dispute resolution in accordance with Article 13 of the Option Agreement with respect to the alleged
breach, which stay and tolling shall last so long as the breaching Party diligently and in good faith cooperates in the prompt resolution of such dispute resolution proceedings. Each Party shall be entitled to offset, against amounts payable to the
other Party under this Agreement, any amounts of damages determined, in a final decision by the applicable court action or other legal proceeding, to be owed to such Party by the other Party based on the other Party’s material breach of this
Agreement. 
 5.3 Termination Upon Insolvency. Either Party may terminate this Agreement upon written notice to the other Party, if,

(a) Termination of License to Artiva. All rights and licenses granted to Artiva hereunder shall terminate, except for any and all
licenses that survive expiration or termination in accordance with the last sentence of Section 3.1(b); provided that if this Agreement is terminated by GCLC pursuant to Section 5.2 or 5.3, any sublicense granted to a Sublicensee
that is not in breach under the applicable sublicense (and whose actions or omissions did not result in a breach by Artiva giving rise to GCLC’s right of termination) will continue as a direct license from GCLC so long as the Sublicensee makes
all payments to GCLC required under Section 3.1 and Section 3.2. 
 (b) Remaining Inventories. Artiva or its Affiliates, to
the extent that such parties continue to have stocks of usable Products that would be subject to payment of Product Royalties pursuant to Section 3.1, may continue to fulfill orders received for Products until [***] months following the date of

Authorities and (B) disclose to GCLC, and grant to GCLC a Right of Reference and Use (as that term is defined in 21 C.F.R. § 314.3(b) or any non-United States equivalent) with respect to, all pre-clinical and clinical data, including pharmacology and biology data, in Artiva’s or its applicable controlled Affiliates’ Control with respect to any Product. 

5.6 Damages; Relief. Termination of this Agreement shall not preclude either Party from claiming any other damages, compensation or
relief that it may be entitled to upon such termination. 
 5.7 Survival. Termination or expiration of this Agreement shall not affect
any rights or obligations of the Parties under this Agreement that have accrued prior to the date of termination or expiration (including any rights or obligations with respect to payments due and owing prior to the date of termination or

licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws. The Parties agree that a Party that is a licensee of such
rights under this Agreement will retain and may fully exercise all of its rights and elections under the provisions of applicable bankruptcy or insolvency laws. The Parties further agree that, in the event of the commencement of a bankruptcy
proceeding by or against a Party to this Agreement under the provisions of applicable bankruptcy or insolvency laws, the other Party will be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property
and all embodiments of such intellectual property, and same, if not already in its possession, will be promptly delivered to it (a) upon any such commencement of a bankruptcy or insolvency proceeding upon its written request therefor, unless

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. 

  
 19 

 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. 
 7.2 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 7.2 IS INTENDED TO OR SHALL LIMIT
OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 7.1 OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE 9 OF THE OPTION AGREEMENT AS APPLIED TO THIS AGREEMENT. 

7.3 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 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 7.
