 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.

1.6 “[***]” 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:

Such amounts shall be determined in accordance with GAAP. 

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

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.

 (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
in calculating any of the foregoing; provided that the obligations under this Section 3.1(c) may be satisfied by the report due by Artiva to GCLC under Section 6.1(c) of the Option Agreement. 

(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, 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.

 (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
performance of the research, development, commercialization or other activities contemplated by this Agreement, including all intellectual property rights therein, shall be as follows: (a) Artiva shall own all Information, discoveries and
inventions made solely by employees, agents or independent contractors of Artiva and all intellectual property rights therein, (b) GCLC shall own all Information, discoveries and inventions made solely by employees, agents or independent
contractors of GCLC and all intellectual property rights therein, and (c) the Parties shall jointly own all Information, discoveries and inventions made jointly by employees, agents or independent contractors of each Party (“Additional
Joint Inventions”) and all intellectual property rights therein. All Patents claiming Joint Inventions shall be referred to herein as “Additional Joint Patents”. Subject to the rights and licenses granted under this
Agreement, any other Selected Product License Agreement and the Option Agreement, each Party shall be entitled to practice, grant licenses to, assign and exploit the Additional Joint Inventions and Additional Joint Patents without the duty of
accounting or seeking consent from the other Party.

 4.2 Patent Prosecution. 

(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,
reexaminations, reissuance, oppositions, revocation proceedings or any other material challenge relating to a given Product Patent in the Territory. Artiva will consult with, and consider in good faith the requests and suggestions of, GCLC with
respect to strategies for filing and prosecuting such Product Patents in the Territory. In the event that Artiva desires to abandon or cease prosecution or maintenance of any Product Patent in the Territory, Artiva shall provide reasonable prior
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
provisions of this Section 4.2(a) are subject to the rights of [***] under the [***]. 
 (b) Additional Joint Patents. Additional
Joint Patents shall be governed by Section 4.2(a). 
 (c) Cooperation. Promptly following the Effective Date, (but no less than
[***] days before any statutory bar date), GCLC will transfer to Artiva all Information concerning the Product Patents in the Territory. GCLC shall cooperate with Artiva and shall execute any power of attorney or similar document, in each case to
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

 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. 

The provisions of this Section 4.4 are subject to the rights of [***] under [***]. 

4.5 Patent Marking. Artiva shall mark Product (or when the character of the product precludes marking, the package containing any such
Product) marketed and sold by Artiva or its Affiliates or Sublicensees in accordance with all applicable Laws relating to patent marking. 

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).

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

Agreement.

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

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

7.1 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 Product in the Territory, or performance of the CMC Activities, by or 

  
 18 

 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 7.1(b)(i), (ii) or (iii) for which GCLC is obligated to indemnify the Artiva Indemnitees under Section 7.1(b). 

(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 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 7.1(a)(i), (ii) or (iii) for which Artiva is obligated to indemnify the
GCLC Indemnitees under Section 7.1(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. 

  
 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.

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. 
 For Products which are sold as Combination Products, the Net Sales
for such Combination Products shall be adjusted by [***].

	3.	 COMPENSATION 

3.1 Initial Payment. Within (a) [***] days after [***], or (b) [***] days after the Effective Date, whichever is later,
Artiva shall pay to GCLC a one-time upfront payment of [***] which represents [***]. 
 3.2
Product License Royalty Payments. 
 (a) Product License Royalty Rates. Artiva shall pay to GCLC royalties on Net
Sales of Products, the manufacture, use or sale of which are claimed by or use any Product Technology, on a country-by-country and Product-by-Product basis during the Product Royalty Term, as calculated by multiplying the applicable portion of aggregate Net Sales of the Product in the Territory by the corresponding royalty rate, as set
forth in the table below, subject to the applicable adjustments in accordance with Section 3.2(e) below (the “Product Royalties”). 

 

			
	 Annual Net Sales of the Product in the Territory
	  	Royalty Rate
	 For that portion of annual aggregate Net Sales of the Product less than or equal to
$[***]
	  	[***]
	 For that portion of annual aggregate Net Sales of the Product greater than [***]
	  	[***]

 (b) Product Royalty Term. Royalties payable under Section 3.2(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 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

  
 7 

 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 in calculating any of the foregoing; provided that the obligations under this Section 3.2(c) may be satisfied by the report due by Artiva to GCLC under
Section 6.1(c) of the Option Agreement. Concurrent with the delivery of the applicable quarterly report, Artiva shall pay the royalty payment due to GCLC pursuant to this Section 3.2 for such calendar quarter. 

(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 Product Technology, including any payments under that certain [***]. 

(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. 

(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 

  
 8 

 to such Third Party which is entitled to be deducted under this Section 3.2(e)(ii) but is not deducted
as a result of the limitation set forth in Section 3.2(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 3.2(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 3.2(e)(ii) and (iii) shall not reduce the Product Royalties
payable to GCLC under Section 3.2 (as reduced under Section 3.2(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 3.2(e). 
 3.3 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 [***].

 (b) Sales Milestone Payments. Artiva shall make the following
one-time, non-refundable and non-creditable sales milestone payments to GCLC when the aggregate annual Net Sales of Products in
the Territory first reach the thresholds specified below. Artiva shall notify GCLC promptly of the achievement of each such sales threshold. Each sales milestone payment shall be made by Artiva within [***] days after the end of the calendar quarter
in which such sales threshold is achieved. To the extent more than one sales threshold is reached in any given calendar year, then the applicable milestone payment for each such achievement shall be due and owing with respect to such calendar year.
For clarification, the total milestone payments payable hereunder if all milestone events are achieved is [***].

 3.4 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. 

  
 10 

 3.5 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 3.5 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. 

3.6 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. 
 3.7 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 

  
 11 

 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
performance of the research, development, commercialization or other activities contemplated by this Agreement, including all intellectual property rights therein, shall be as follows: (a) Artiva shall own all Information, discoveries and
inventions made solely by employees, agents or independent contractors of Artiva and all intellectual property rights therein, (b) GCLC shall own all Information, discoveries and inventions made solely by employees, agents or independent
contractors of GCLC and all intellectual property rights therein, and (c) the Parties shall jointly own all Information, discoveries and inventions made jointly by employees, agents or independent contractors of each Party (“Additional
Joint Inventions”) and all intellectual property rights therein. All Patents claiming Joint Inventions shall be referred to herein as “Additional Joint Patents”. Subject to the rights and licenses granted under this
Agreement, any other Selected Product License Agreement and the Option Agreement, each Party shall be entitled to practice, grant licenses to, assign and exploit the Additional Joint Inventions and Additional Joint Patents without the duty of
accounting or seeking consent from the other Party within the Party’s respective territory. 
 4.2 Patent Prosecution. 

(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, re-issue proceedings and re-examinations) 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, re-examinations, re-issuance, oppositions, revocation proceedings or any
other material challenge relating to a given Product Patent in the Territory. Artiva will consult with, and consider in good faith the requests and suggestions of, GCLC with respect to strategies for filing and prosecuting such Product Patents in
the Territory. In the event that Artiva desires to abandon or cease prosecution or maintenance of any Product Patent in the Territory, Artiva shall provide reasonable prior 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 

  
 12 

 maintenance of Product Patents outside the Territory to the extent such activities could affect the Product
Patents in the Territory. 
 (b) Additional Joint Patents. Additional Joint Patents shall be governed by Section 4.2(a).
 
 (c) Cooperation. Promptly following the Effective Date, (but no less than [***] days before any statutory bar
date), GCLC will transfer to Artiva all Information concerning the Product Patents in the Territory. GCLC shall cooperate with Artiva and shall execute any power of attorney or similar document, in each case to 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, Additional Joint Patents or Product Technology related to any Existing Third Party Agreements, 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. 

(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. Unless otherwise agreed by the Parties, the Parties shall
jointly bring and control an infringement action with respect to any Product Technology that is related to the [***], and equally bear the related expense. 

(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. 

  
 13 

 (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. Unless otherwise agreed by the Parties, the Parties shall jointly control the defense 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 of any Product Technology that is related to the AbClon Agreement, and each Party shall equally bear the
related 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 

  
 14 

 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. 
 4.5
Patent Marking. Artiva shall mark Product (or when the character of the product precludes marking, the package containing any such Product) marketed and sold by Artiva or its Affiliates or Sublicensees in accordance with all applicable Laws
relating to patent marking. 
 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. TERM AND TERMINATION 
 5.1
Term. This Agreement shall become effective on the Effective Date and, unless earlier terminated pursuant to this Article 5, shall remain in effect until the expiration of the last Product Royalty Term in the Territory (the
“Term”). 
 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, at any time, the other Party (a) files in any court or agency pursuant to any statute or regulation of any state, country or jurisdiction, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the
appointment of a receiver or trustee of such other Party or of its assets, (b) is served with an involuntary petition against it, filed in any insolvency proceeding that is not dismissed within ninety (90) days after the filing thereof,

  
 15 

 or (c) makes an assignment of the assets associated with this Agreement for the benefit of its
creditors. 
 5.4 Termination by Artiva. Artiva may terminate this Agreement in its entirety without cause upon ninety
(90) days prior written notice to GCLC. 
 5.5 Effects of Expiration or Termination of this Agreement. Upon any
expiration or termination of this Agreement, all rights and obligations of the Parties shall terminate entirely, except as provided in this Section 5.5 and Section 5.7 and the sections referenced therein and: 

(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 3.2(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 3.2 and Section 3.3. 
 (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 3.2, may continue to fulfill orders received for Products until [***] months
following the date of termination. For Products sold by Artiva or its Affiliates after the effective date of a termination, Artiva shall continue to pay Product Royalties pursuant to Section 3.2, as applicable. 

(c) Additional Effects of Termination. Upon any termination of this Agreement, except termination of this Agreement by Artiva
under Section 5.2, effective as of such termination, Artiva shall promptly (A) assign and transfer (or cause to be assigned and transferred) to GCLC or its designee (and provide copies of) all Regulatory Materials and Regulatory Approvals
held in the name of Artiva, or any Affiliate it controls (within the meaning of Section 1.1 of the Option Agreement), relating to any Product, including related correspondence with Regulatory 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
expiration). Notwithstanding anything to the contrary, the following provisions shall survive any expiration or termination of this Agreement: Articles 1 and 8 and Sections 2.5, 3.2(b) (final sentence only), 3.5 (for the term stated
therein), 4.1, 5.5, 5.6, 5.7, 5.8, 

  
 16 

 6.5, 7.1, 7.2 and 7.3 (for [***] years), as well as Article 1 (Definitions) to the extent necessary to give
meaning to terms defined therein, Articles 9 and 13 and Sections 14.2 through Section 14.11 of the Option Agreement as applied to this Agreement pursuant to Section 8.2. 

5.8 Rights under Bankruptcy or Insolvency Laws. All rights and licenses granted under or pursuant to this Agreement by one Party
to the other Party are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws, 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 the bankrupt Party elects to continue to perform all of its
obligations under this Agreement, or (b) if not delivered pursuant to clause (a) above, following the rejection of this Agreement by or on behalf of the bankrupt Party upon written request therefor by the other Party.

	7.	 INDEMNIFICATION AND LIMITATION OF LIABILITY 

7.1 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 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; (iii) the use or application of a Third Party License in the
development, manufacture, commercialization or other disposal of any Product in the Territory; or (iv) 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 7.1(b)(i), (ii) or (iii) for which GCLC is
obligated to indemnify the Artiva Indemnitees under Section 7.1(b). 
 (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) activities of, or on behalf of GCLC or GCLC Subsidiaries, licensee or sublicensees (other than Artiva and its Affiliates and Sublicensees) for the development, manufacture or commercialization of any Product, that give rise to
a Third Party claim against an Artiva Indemnitee; (ii) the breach of any 

  
 20 

 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 GCLC Subsidiaries 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 7.1(a)(i), (ii) or (iii) for which Artiva is obligated to indemnify the GCLC Indemnitees under Section 7.1(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. 

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 

  
 21 

 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.
