Work Order until the later of: (i) the [***] ([***]) anniversary of completion of such Services; and (ii) expiration of the minimum retention period required by applicable laws, rules and regulations. 

 

	6.	 OWNERSHIP OF INTELLECTUAL PROPERTY.



 6.1 Rights under Master Agreement. Except as provided in Section 2, each party
understands and agrees that this Agreement does not modify the ownership or rights of GCLC, nor the rights granted to Artiva, with respect to the GCLC Core Technology as established pursuant to the Master Agreement. 

6.2 Ownership of Arising Intellectual Property. 

Inventorship of Arising Intellectual Property will be determined in accordance with principles of U.S. patent law. GCLC shall
own all Arising Intellectual Property invented solely by GCLC employees, and any Arising Intellectual Property invented jointly with employees of Artiva and/or Merck shall be jointly owned between GCLC and Artiva and/or Merck. 

6.3 Patent Prosecution and Enforcement. GCLC shall promptly disclose to Artiva in writing the conception,
creation or discovery of any Arising Intellectual Property to which one or more patent applications may be filed. Artiva may grant to Merck under the Collaboration Agreement any right that Artiva has under the Master Agreement or this Agreement,
including any right to prepare, file, prosecute (including conduct any interferences, reissue proceedings and reexaminations), maintain, enforce, and bring and control any infringement action with respect to any GCLC Core Patents, Joint Patents, or
Patents within the 

  
 13. 













 
Arising Intellectual Property in accordance with the Master Agreement and this Agreement. Filing of patent applications shall indicate GCLC as the owner of the applicable patents, where
appropriate, in accordance with the provision of this Section 6, and Artiva shall promptly disclose to GCLC copies of any and all such patents applications as filed, together with notice of their respective filing dates and serial numbers. 

 

	 	(a)	 Arising GCLC Core IP. Filing, prosecution, and enforcement of patent applications covering Arising GCLC
Core IP shall be governed by Sections 8.2-8.4 of the Master Agreement. Any such patent applications shall not include any reference to or disclosures regarding the Antibody Binders, Collaboration Candidates,
Merck Products, or Arising Merck Product IP. GCLC shall not include any Results in any patent applications within the Arising GCLC Core IP without Artiva’s prior written consent; 



 

	 	(b)	 Arising Merck Product IP. Artiva and/or Merck shall have the right to file, prosecute (including during
administrative proceedings such as interference, derivation, opposition, reexamination, reissue, supplemental examination, Inter Partes Review and Post-Grant Review proceedings), enforce, and defend Arising Merck Product IP, regardless of
ownership or inventorship. GCLC agrees to cooperate fully with Artiva and/or Merck and provide any information and assistance that either may reasonably request for the filing, prosecution and maintenance of the Arising Merck Product IP, including
the execution of any applicable powers of attorney or similar documents. In the event that Artiva and/or Merck is unable to initiate or prosecute an action to enforce or defend Arising Merck Product IP without GCLC, GCLC will join such action
voluntarily and will execute and cause its Affiliates to execute all documents necessary for Artiva and/or Merck to initiate litigation to prosecute and maintain such action. 



 

	7.	 CONFIDENTIALITY. 



7.1 Confidential Information. For purpose of this Agreement, “Confidential
Information” shall mean any and all information disclosed or made available by or on behalf of a party (the “Disclosing Party”) to the other party (the “Receiving Party”), whether in
oral, written, graphic, electronic or other form. However, notwithstanding the foregoing, all Arising GCLC Core IP that is solely owned by GCLC shall be deemed Confidential Information of GCLC, and all Arising GCLC Core IP that is jointly owned
shall be deemed the Confidential Information of both Parties. All Arising Merck Product IP shall be deemed Confidential Information of Artiva, in each case hereunder and under the Master Agreement. 

  
 14. 













 7.2 Exceptions. Confidential Information of a Disclosing Party shall
not include any information that the Receiving Party can demonstrate by competent evidence: (a) is or becomes publicly known other than as a result of any breach of this Agreement by the Receiving Party; (b) is disclosed to the Receiving
Party on a non-confidential basis by a third party who rightfully possesses the information; (c) was known to the Receiving Party prior to its first receipt from the Disclosing Party (provided that the
exception set forth in this clause (c) shall not apply to Results, other Work Product or Arising Intellectual Property); or (d) was independently developed by the Receiving Party outside the scope of this Agreement and without use of or
reference to the Confidential Information of the Disclosing Party. 
 7.3 Confidentiality Obligation. During
the term of this Agreement and thereafter, the Receiving Party shall maintain all Confidential Information of the Disclosing Party as confidential and shall not disclose any such Confidential Information or use any such Confidential Information for
any purpose, except (a) as expressly authorized by this Agreement, (b) as permitted by Section 7.4, or (c) to its employees, agents, consultants, Artiva-approved subcontractors and other representatives who require access to such
information to accomplish the purposes of this Agreement so long as such persons are under obligations regarding the confidentiality of the Confidential Information and the ownership of Work Product and Arising Intellectual Property (including,
without limitation, Arising GCLC Core IP and Arising Merck Product IP) that are consistent with, and no less protective to GCLC than, the terms of this Agreement. The Receiving Party may use the Confidential Information of the Disclosing Party only
to the extent required to accomplish the purposes of this Agreement. The Receiving Party shall use at least the same standard of care as it uses to protect its own confidential information to ensure that its employees, agents, consultants,
sublicensees (including Merck and any of its Affiliates, employees, agents, consultants, sublicensees and subcontractors) GCLC-approved subcontractors and other representatives do not disclose or make any unauthorized use of the Confidential
Information. The Receiving Party shall promptly notify the Disclosing Party upon discovery of any unauthorized use or disclosure of the Confidential Information. 

7.4 Authorized Disclosure. Notwithstanding the provisions of Section 7.3, the Receiving Party may disclose
Confidential Information of the Disclosing Party, without violating its obligations under this Agreement, to the extent the disclosure is required by applicable law or by a valid order of a court or other governmental body having jurisdiction,
provided that the Receiving Party gives reasonable prior written notice to the Disclosing Party of such required disclosure and, at the Disclosing Party’s request and expense, cooperates with the Disclosing Party’s efforts to contest such
requirement, to obtain a protective order requiring that the Confidential Information so disclosed be used only for the purposes for which the order was issued or the law or regulation required, and/or to obtain other confidential treatment of the
Confidential Information so disclosed. 

  
 15. 













 7.5 GCLC Press Release. A public announcement may be made by GCLC on
or following the date hereof substantially in the form attached hereto as Exhibit F. 
 7.6 Third Party
Confidential Information. The Disclosing Party shall not disclose to the Receiving Party any confidential or proprietary information that belongs to any third party.

8.3 Artiva Representations and Warranties. Artiva represents and warrants that: (a) as of the effective
date, except for a Supply Agreement and/or Quality Agreement (to be negotiated), the Collaboration Agreement attached hereto in Exhibit C hereto is the entire agreement between Artiva and Merck with respect to the subject matter hereof, and

and (c) Artiva will render its activities under this Agreement, if any, in accordance with high professional standards customary to its industry and in compliance with the terms of this Agreement, the terms of the Work Orders, and all
applicable laws, rules and regulations. 

  
 16. 













 8.4 No Debarment. The mutual covenant in Section 11.3(a) of the
Master Agreement is incorporated by reference herein and deemed to also apply with respect to the performance of the Services by GCLC and the use of the Work Product and Arising Intellectual Property by Artiva, in each case with respect to the Merck
Products. 
 8.5 Anti-Bribery. Each party represents, warrants and covenants that it and its officers, employees,
directors, consultants, contracts and agents, in connection with the performance of its respective obligations under this Agreement, shall not cause the other party to be in violation of any applicable anti-bribery legislations anywhere in the
world. 
 8.6 Disclaimer of Warranties. EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER PARTY MAKES
ANY REPRESENTATION OR WARRANTY TO THE OTHER PARTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY, OR FITNESS FOR A PARTICULAR PURPOSE.

 8.7 Limitation of Liability. EXCEPT FOR BREACH OF ARTICLE 7, IN NO EVENT SHALL EITHER PARTY BE LIABLE
TO THE OTHER FOR ANY LOST PROFITS, LOST SAVINGS, OR ANY OTHER INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT;
provided, however, that this Section 8.7 shall not be construed to limit either party’s indemnification obligations under Article 10. 
  

	9.	 TERM AND TERMINATION. 



9.1 Term. The term of this Agreement shall commence on the Effective Date and, unless earlier terminated in
accordance with this Article 9, shall expire upon the termination of the Collaboration Agreement. 
 9.2
Termination for Material Breach. Each party shall have the right to terminate this Agreement in its entirety or any Work Order immediately upon written notice to the other party if the other party materially breaches its obligations under
this Agreement or any Work Order and, after receiving written notice identifying such material breach in reasonable detail, fails to cure such material breach within 60 days from the date of such notice (or within 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 60 day period, the non-breaching party may terminate this Agreement or the applicable Work Order following such 60 day period only if the breaching party shall have failed to commence substantial remedial actions within such 60 day
period and to use reasonable efforts to pursue the same. Any right to terminate under this Section 9.2 shall be stayed and the cure period tolled in the event that, during any cure period, the breaching party shall have initiated dispute
resolution 

  
 17. 













 
in accordance with Section 11.5 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. Either party may terminate any Work Order immediately upon written notice to the other party if the other party is in breach of Section 8.4. 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. If such notice of breach is for breach of a Work Order, such notice shall note the specific Work Order under which such breach is claimed. 

9.3 Termination at Will. Artiva may terminate any Work Order without cause upon 90 days’ prior written
notice to GCLC. 
 9.4 Consequences of Termination. In the event of early termination of any individual Work
Order for a Project, or in the event of termination of all Work Orders for all Projects by Artiva for reasons stated above, Artiva shall pay to GCLC all sums owing to GCLC for Services completed up to the effective termination date of such Work
Order(s) and all non-cancelable obligations reasonably incurred before the effective date of termination pursuant to such Work Order(s) within 30 days after the effective date of termination. Subject to
the preceding sentence, GCLC shall refund to Artiva any prepaid amounts not earned by GCLC prior to the date of such termination, in which event, the parties shall mutually discuss in good faith any compensation and costs payable to GCLC for its
preparatory work to conduct any Work Order, including non-cancelable costs and compensations for its subcontractors. In the event that this Agreement is terminated under Section 9.2 due to Artiva’s
material breach of this Agreement (other than a material breach by Artiva arising due to Merck’s material breach of its obligations under the Collaboration Agreement), GCLC agrees to allow Merck to step in and cure the breach (to the extent the
breach is curable) and assume Artiva’s rights and obligations under this Agreement within a reasonable period to be agreed upon between GCLC and Merck. In this case, the licenses and exclusivity provided for in Sections 2.2 and 2.4 shall
continue through the Merck Product Term subject to Merck’s cure of such material breach (to the extent the breach is curable) and assumption of Artiva’s payment obligations owed to GCLC under this Agreement. In the event that this
Agreement is terminated by Artiva under Section 9.2 due to GCLC’s breach, the licenses and exclusivity provided for in Sections 2.2 and 2.4 shall continue through the Merck Product Term, and with respect to any Merck Product at the time of
termination under Section 9.2, if the criteria have been met under the Collaboration Agreement for Artiva to receive any applicable milestone payments attributable to (i) [***] and (ii) [***], then Artiva shall be obligated to continue to pay
Merck Product Payments to GCLC with respect to such Merck Product during the Merck Product Term. For clarity, in the event of termination, the requirements of Section 10.5(c) in the Master Agreement shall not apply. 

  
 18. 













 9.5 Survival. Expiration or termination of this Agreement
shall not relieve the parties of any obligation accruing prior to such expiration or termination. Sections 2.1 (last sentence only), 2.2, 2.4, 3.5, 3.6, 4.3, 5.1, 5.3, 5.4, 8.6, 8.7,and 9.4 and 9.5, and Articles 6, 7 and 10 shall survive
expiration or termination of this Agreement. 
  

	10.	 INDEMNIFICATION. 



10.1 Artiva Indemnification. Artiva hereby agrees to save, defend, indemnify and hold harmless GCLC and its
officers, directors, employees, consultants and agents (“GCLC Indemnitees”) from and against any and all losses, damages, liabilities, expenses and costs, including reasonable legal expense and
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 Merck 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. 

10.2 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.

 10.3 Indemnification Procedures. A party claiming indemnification under this Article 10 (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 of any
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 

  
 19. 













 
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 10.3. The Indemnitee may participate in such defense by
counsel of its own selection and at its own expense. 
 10.4 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. 
 10.5 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 10.5 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 10 or any other
liability to compensate GCLC under this Agreement. 
  

	11.	 GENERAL PROVISIONS. 



11.1 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. 
 11.2 Independent Contractor 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 the other 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. 

  
 20. 













 11.3 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, except in the case of required regulatory submissions
(with prior written notice to the other party),    However, in its use of the Arising GCLC Core IP 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. 
 11.4 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 11.4 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. 
 11.5 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 11.5. Capitalized terms used but not otherwise defined in this Section 11.5 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. 

  
 21. 













 (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. 

11.6 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. 
 11.7 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. This Agreement may not be changed, modified, amended or supplemented except by a written instrument signed by both parties. 

11.8 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. 

11.9 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. 

  
 22. 













 11.10 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 actual receipt; (b) if mailed by international courier, seven
(7) days after the date of postmark; (c) if delivered by international express courier, three (3) days after the date of pick up; or (d) if delivered by electronic mail, upon confirmation of transmission.
