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.

 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
the party to be notified at its address given below, or at any address such party has previously designated by prior written notice to the other. Notice shall be deemed sufficiently given for all purposes upon the earliest of: (a) the date of
