or offer to sell Licensed Products prior to the exercise of this Option and the execution of an Amended License Agreement that includes a license to the Licensed Patents covering such Licensed Product. During the Option Period (and if Graphite
exercises the Option, during the Negotiation Period), unless otherwise agreed to by Graphite in writing in its sole and absolute discretion, Stanford will not grant to any Third Party any right or license, or option to negotiate or acquire a right
or license, under Stanford’s interest in the Optioned Patents in the Optioned Field of Use to make, have made, use, import, offer to sell and sell or otherwise commercially exploit: (i) the Licensed Products in the Licensed Territory nor

 Page 3 of 13 

	3.2	 Term. The term of the right to elect to exercise this Option shall commence on the Effective Date and
expires on the earliest of (a) termination of the License Agreement, (b) Graphite’s termination as provided in Section 8.1 below, or (c) the eighteen (18) month anniversary of the Effective Date, provided that such
eighteen (18) month anniversary of the Effective Date may be extended, (i) upon written notice of Graphite provided no later than thirty (30) days prior to such eighteen (18) month anniversary for an additional one (1) year
and (ii) upon written request of Graphite provided no later than thirty (30) days prior to the thirty (30) month anniversary of the Effective Date and mutual agreement of Stanford (not to be unreasonably withheld) for another
additional one (1) year (such period, as it may be extended in accordance with this Section 3.2, the “Option Period”). Notwithstanding the provisions of Section 3.2(c)(i) or 3.2(c)(ii), no such request of Graphite as
contemplated thereby shall be valid if upon the date of such request Stanford shall have provided Graphite with written notice of termination of the License Agreement pursuant to Section 15.2 of the License Agreement and neither Stanford has
withdrawn such notice nor Graphite shall have remedied the grounds for termination in accordance with the terms of Section 15.2 of the License Agreement. 

 

	3.3	 Exercise. Graphite may exercise the Option by providing a written notice to Stanford if [***] or
Stanford otherwise agrees in writing. Graphite may exercise the Option at any time during the Option Period; provided, however, that no such exercise shall be valid if upon the date of such exercise Stanford shall have provided Graphite with written
notice of termination of the License Agreement pursuant to Section 15.2 of the License Agreement and neither Stanford has withdrawn such notice nor Graphite shall have remedied the grounds for termination in accordance with the terms of
Section 15.2 of the License Agreement. The Option is a series of options with respect to each of the Optioned Patents, such that Graphite may exercise the Option with respect to one or more of the Optioned Patents from time to time during the
Option Period. 

  

	3.4	 Amendment of License Agreement. If Graphite elects to exercise the Option under Section 3.3,
Stanford and Graphite will promptly execute and deliver a written amendment to the License Agreement, as further described below, (such amended license agreement, an “Amended License Agreement”). An Amended License Agreement would
provide as follows: (a) the term “Licensed Patents” as set forth in the License Agreement shall be amended by adding the Optioned Patents for which the Option was exercised to such definition; and (b) the term
“Technology” as set forth in the License Agreement shall be amended by adding the Optioned Technology for which the Option was exercised to such definition, with the Optioned Exclusive Technology and Optioned Nonexclusive Technology being
added to the applicable portions of Appendix C of the License Agreement. Graphite and Stanford will use good faith efforts to execute and deliver an Amended License Agreement within three (3) months after the date of exercise of the Option
under Section 3.3 (the “Negotiation Period”). The parties acknowledge that absent any additional language related to [***] or any other third party obligations that Stanford may become aware of during the Option Period and/or
Negotiation Period, the terms of the Amended License Agreement will remain the same as those in the License Agreement in all material respects except as outlined in Sections 3.5 and 6 of this Agreement. The parties will negotiate the definitive
terms of such Amended License Agreement in good faith.

	3.5	 Additional Equity Grants. 

 

	 	(A)	 Within sixty (60) days after the execution and delivery of the first Amended License Agreement, Graphite
will grant to Stanford 222,735 shares of common stock in Graphite. For clarity, there is a single grant of 222,735 shares of common stock whether or not the Option is exercised once in its entirety or in a series of exercises, and if the Option is
exercised in a series of exercises, such grant shall be made upon the delivery of the Amended License Agreement resulting from the first of such exercises (such Amended License Agreement, the “First Amended Agreement”).

  

	 	(B)	 Provided that the First Amended Agreement has been executed and delivered, Graphite will issue Stanford,
without further consideration, 98,623 additional shares of common stock in Graphite at the second tranche of the Series A preferred stock financing of Graphite as of the closing of such tranche, as reflected in the pro forma capitalization table set
forth in Exhibit B to the License Agreement. For clarity, there is a single grant of 98,623 shares of common stock whether or not the Option is exercised once in its entirety or in a series of exercises. In the event that such second tranche closing
has occurred prior to the execution and delivery of the First Amended Agreement, such additional shares shall be issued at the same time as the shares being issued under Section 3.5(A). In the event that Graphite closes a financing of a series
of preferred stock other than Series A preferred stock prior to the closing of the second tranche of the Series A preferred stock financing, the number of shares issuable to Stanford pursuant to this Section 3.5(B) will be adjusted so that such
number equals [***]% of the common shares of Graphite issued and outstanding on a Fully-Diluted Basis as of the closing of such other preferred stock financing. The anti-dilution protection under this Section 3.5(B) will continue until the
Dilution Trigger has been achieved. If the Dilution Trigger is reached or exceeded during a specific round of funding, the anti-dilution protection under this Section 3.5(B) will extend to the total amount of funding raised through the Dilution
Trigger only and shall not apply to any amounts raised by Graphite in such round of funding in excess of the Dilution Trigger. 

  

	 	(C)	 After the first exercise of the Option but not later than the start of the Negotiation Period and pursuant to
Section 3.5(A) or Section 3.5(B), Graphite will provide Stanford with its current capitalization table and [***]. Upon written request of Stanford, Graphite will issue [***]% of all shares granted to Stanford pursuant to this
Section 3.5 directly to and in the name of the inventors or their heirs according to the inventor list that Stanford will provide prior to issuance. 

  

	3.6	 Materials Transfer. To the extent Stanford has legal rights to do so, the exercise of the Option would
also include materials transfer of any materials included in the Option Technology as is provided in the License Agreement for the programs licensed thereunder in the Initial Field of Use. 

  
 Page 5 of 13 

	3.7	 Retained Rights. Stanford retains the right, on behalf of itself, Stanford Health Care, Lucile Packard
Children’s Hospital at Stanford and all other non-profit research institutions, to practice the Optioned Patents and use Optioned Technology in the Optioned Field of Use for any non-profit purpose, including sponsored research and collaborations. Graphite agrees that, notwithstanding any other provision of this Agreement, it has no right to enforce the Optioned Patents or Optioned
Technology against any such institution. Stanford and any such other institution have the right to publish any information included in the Optioned Technology or an Optioned Patent or any other information that may result from further research.

  

	3.8	 Specific Exclusion. Stanford does not: 

 

	 	(A)	 grant to Graphite any other licenses, implied or otherwise, to any patents or other rights of Stanford other
than those rights granted under Optioned Patents, regardless of whether the patents or other rights are dominant or subordinate to any Optioned Patent or are required to exploit any Optioned Patent or Optioned Technology; 

 

	 	(B)	 agree to furnish to Graphite any technology or technological information other than the Optioned Technology or
to provide Graphite with any assistance; or 

  

	 	(C)	 make any representation or warranty, and expressly disclaims any such representation or warranty, express or
implied, that it is the sole-owner of the Additional Inventions. 

  

	4.	 GOVERNMENT RIGHTS 

This Agreement is subject to Title 35 Sections 200-204 of the United States Code. Among other
things, these provisions provide the United States Government with nonexclusive rights in the Optioned Patents. They also impose the obligation that Licensed Product sold or produced in the United States be “manufactured substantially in the
United States.” Graphite will ensure all obligations of these provisions are met. 
  

	5.	 DILIGENCE 

Graphite agrees to exercise due diligence in conducting research on potential commercial applications for Optioned Patents and Optioned
Technology on terms substantially similar to those provided in the License Agreement. 
  

	6.	 CONSIDERATION 

 

	 	A.	 No separate consideration shall be due for the grant or upon exercise of the Option. Parties agree that the
License Issue Fee and the Total Equity Interest (equity grant under the License Agreement and this Option Agreement) is in consideration for the Licensed Patents and Optioned Patents. An additional $10,000 will be included as part of the License
Issue Fee once S19-501B case is included in the License Agreement via an amendment per Section 3.4. 

  
 Page 6 of 13 

	 	B.	 Patent Costs: Within 30 days after receiving a reasonably detailed statement of Stanford’s actual costs
incurred in the filing, prosecution or maintenance of the Optioned Patents in accordance with Stanford’s usual practice, provided Stanford will provide further details if Graphite requests such for a specific invoice, Graphite will reimburse
Stanford: 

  

	 	a.	 $[***] to offset Optioned Patent’s patenting expenses (specifically for Stanford Docket [***]), including
but not limited to interference or reexamination matters, inventorship or ownership disputes and opposition proceedings incurred by Stanford before the Effective Date; and 

 

	 	b.	 for all Optioned Patent’s patenting expenses after the Effective Date and during the term of the Option
and any Negotiation Period, including but not limited to interference or reexamination matters, inventorship disputes and opposition proceedings, in each case, reasonably incurred by Stanford after the Effective Date, Stanford will pay the fees
prescribed for large entities to the United States Patent and Trademark Office. If Graphite requests that Stanford pay fees prescribed for a small entity, then Graphite will bear all responsibility for notifying Stanford if its status changes to
large entity. Graphite is herein notified that the determination of entity size for the United States Patent and Trademark Office depends not only on the size of Graphite, but also may depend on the size of any companies to which Graphite has
granted licenses. 

  

	7.	 INDEMNITY 

  

	7.1	 Indemnification. Graphite will indemnify, hold harmless, and defend all Stanford Indemnitees against any
claim of any kind arising out of or related to the exercise of any rights granted Graphite under this Agreement, reliance upon this Agreement or the execution of the License Agreement, or the breach of this Agreement by Graphite.

  

	7.2	 No Indirect Liability. Stanford is not liable for any special, consequential, lost profit, expectation,
punitive or other indirect damages in connection with any claim arising out of or related to this Agreement, whether grounded in tort (including negligence), strict liability, contract, or otherwise, and regardless of any notice of the possibility
of such damages. Except for liability arising under its indemnification obligations under Section 7.1 or for any use by Graphite of the Optioned Patents and Optioned Technology that is outside the scope of the rights to such intellectual
property granted to Graphite under this Agreement, Graphite is not liable for any special, consequential, lost profit, expectation, punitive or other indirect damages in connection with any claim arising out of or related to this Agreement, whether
grounded in tort (including negligence), strict liability, contract, or otherwise, and regardless of any notice of the possibility of such damages.. Furthermore, despite the obligation to negotiate during the Negotiation Period in good faith,
neither Stanford nor Graphite shall have any liability for refusing to compromise on any issue, accepting risks associated with any unresolved legal claim, or for failing to execute any agreement, including the License Agreement. 

  
 Page 7 of 13 

	7.3	 Workers’ Compensation. Graphite will comply with all statutory workers’
compensation and employers’ liability requirements for activities performed under this Agreement. 

  

	7.4	 Insurance. During the term of this Agreement, Graphite will maintain such Commercial General Liability
Insurance and Product Liability Insurance as are required under the terms of the License Agreement. 

  

	8.	 TERMINATION 

  

	8.1	 Termination by Graphite. Graphite agrees to promptly notify Stanford at any time during the Option
Period when Graphite has determined not to exercise the Option. Graphite also agrees to provide Stanford, in reasonable detail, the basis for this determination. 

 

	8.2	 No Residual Rights. Upon expiration or termination of this Option, or upon Graphite’s decision not
to enter into a License Agreement, whichever is earlier, Graphite will have no residual or other rights in Licensed Patents or Technology. 

  

	9.	 STANFORD NAMES AND MARKS 

Graphite will not use (i) Stanford’s name or other trademarks, (ii) the name or trademarks of any organization related to
Stanford, or (iii) the name of any Stanford faculty member, employee, student or volunteer. This prohibition includes, but is not limited to, use in press releases, advertising, marketing materials, other promotional materials, presentations,
case studies, reports, websites, application or software interfaces, and other electronic media. Notwithstanding the foregoing, Graphite may include Stanford’s name in factual statements in legal proceedings, patent applications, regulatory
filings and, as applicable, in biographies of its officers, directors, employees and advisors. In addition, Graphite may make a short factual statement that identifies Stanford as the grantor of the rights granted under this Agreement to actual or
potential investors or acquirers, as well as in the “About Graphite” or other similar section of the Graphite website. 
  

	10.	 ASSIGNMENT 

Graphite may not assign this Agreement except in connection with a permitted assignment of the License Agreement. Upon a permitted assignment
of this Agreement, Graphite will be released of liability under this Agreement and the term “Graphite” in this Agreement refer solely to the applicable assignee.
