which is made with, uses or incorporates any Technology.

“Licensed Territory” means worldwide.

“Net Sales” means, with respect to a Licensed Product, the gross revenue derived by Graphite or its Affiliates or Sublicensees (each, a “Selling Party”) on the sale, transfer or other disposition of such Licensed Product to Third Parties (including but not limited to any distributors), less the following items to the extent included in gross revenue and specifically allocated to such sale, transfer or other disposition of such Licensed Product and actually taken, paid, accrued, allowed, included or allocated consistent with such Selling Party’s practice and applicable accounting standards, consistently applied:

the portion of any payment made upon achievement of milestones that are the same or substantially the same as ones for which a payment is due under this Agreement up to the milestone payment amount due under this Agreement. However, the applicable Nonroyalty Sublicensing Consideration percentage shall apply in such case to any amount received by Graphite that exceeds the amount of the milestone payment required to be made to Stanford for the equivalent milestone. For example, [***];

Profit Sharing Income received under a profit-sharing arrangement, where “Profit Sharing Income” means amounts received by Graphite under an agreement between Graphite and a Sublicensee under which Graphite or its Affiliate is funding a share of the development of the Licensed Product after a Sublicense has been granted and receives a reasonably proportionate share of net profit from such Sublicensee specifically resulting from any actual sales of Licensed Products but will include any milestone payments based on achievement of designated net sales levels; and

payments in connection with a Change of Control of Graphite provided there’s no Sublicense granted as part of the Change of Control transaction to the acquirer in such transaction or its Affiliates.

“Rx Field of Use” means human prophylactics and therapeutics outside the Initial Field of Use, excluding commercialization of research reagents and research products.

“Stanford Indemnitees” means Stanford, Stanford Health Care and Lucile Packard Children’s Hospital at Stanford and their respective trustees, officers, employees, students, agents, faculty, representatives, and volunteers.

“Sublicense” means any agreement between Graphite and a Third Party or between any Sublicensee and a Third Party under which such Third Party is granted any rights to Stanford’s interest in the Licensed Patents and/or Technology under the license granted by Stanford to Graphite under Article 3, regardless of the name given to the agreement by the parties.

“Sublicensee” means any Third Party which enters into a Sublicense, for so long as such Sublicense remains in effect.

Technology may or may not be confidential in nature.

“Third Party” means any person or entity other than Stanford, Graphite or Graphite’s Affiliates.

“Valid Claim” means, with respect to a particular country, any claim of any pending Licensed Patent application or an issued and unexpired Licensed Patent in such country that (a) has not been revoked or held unenforceable or invalid by a decision of a court or governmental agency of competent jurisdiction, which decision is unappealable or unappealed within the time allowed for appeal and (b) has not been abandoned, disclaimed, denied or admitted to be invalid or unenforceable through reissue or disclaimer or otherwise in such country. Notwithstanding the foregoing, on a country-by-country basis, a claim of a pending Licensed Patent application pending for more than [***] from the date of receipt of first office action will not be considered a Valid Claim for purposes of this Agreement unless and until such claim issues after which it will be considered a Valid Claim.

GRANT

Grant. Subject to the terms and conditions of this Agreement, Stanford grants Graphite (a) a license to Stanford’s rights in the Licensed Patents and Technology in the Initial Field of Use to make, have made, use, have used, sell, have sold, offer for sale, import, have imported and export Licensed Products in the Licensed Territory and (b) a license to Stanford’s rights in the Technology in the Rx Field of Use to make, have made, use, have used, sell, have sold, offer for sale, import, have imported and export Licensed Products in the Licensed Territory. The Parties acknowledge and agree that “use” includes research and development.

Exclusivity. The license to the Licensed Patents, including the right to sublicense under Section 3.6 is Exclusive in the Initial Field of Use beginning on the Effective Date and ending, on a country-by-country basis, on the expiration of the last-to-expire Valid Claim included in the Licensed Patents in such country. The license to the Technology indicated as Exclusive under the heading “Exclusivity” in Appendix C, including the right to sublicense under Section 3.6, is (a) Exclusive in the Initial Field of Use beginning on the Effective Date and ending on the expiration of the Royalty Term for all Licensed Products in all countries of the Licensed Territory and (b) non-exclusive in the Rx Field of Use. The license to the Technology indicated as Non-Exclusive under the heading “Exclusivity” in Appendix C is non-exclusive in the Initial Field of Use and Rx Field of Use. After the expiration of the Royalty Term for all Licensed Products in all countries of the Licensed Territory but not upon Termination in accordance with Sections 15.2 and 15.3, the licenses granted under Section 3.1 shall be perpetual, irrevocable, non-exclusive, and fully paid up. Except as expressly provided in Section 3.1 and this Section 3.2, Graphite understands and agrees that no other rights are being granted to Licensed Patents, or any other intellectual property owned or controlled by Stanford, either expressly or by implication, estoppel or otherwise.

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 Licensed Patents and use Technology in the Initial 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 Licensed Patents or Technology against any such institution. Stanford and any such other institution have the right to publish any information included in the Technology or a Licensed Patent or any other information that may result from further research. For the avoidance of doubt, Stanford is free to exploit Licensed Patents and Technology outside the Initial Field of Use and allow others to do so subject to Graphite’s exclusive rights under this Section 3.

Specific Exclusion. Stanford does not:

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

commit to Graphite to bring suit against third parties for infringement, except as described in Section 14; and

agree to furnish to Graphite any technology or technological information other than the Technology or to provide Graphite with any assistance.

Affiliates. Graphite may exercise its rights and fulfill all or any part of its obligations under this Agreement through its Affiliates, and Graphite’s Affiliates shall have the same rights under this Agreement (including the right to grant Sublicenses, as set forth in Article IV) as the rights granted to Graphite. Any such Affiliates shall exercise such rights and perform such obligations in accordance with the terms and conditions of this Agreement, to the extent applicable to such exercise or performance, and Graphite shall be responsible and liable for the performance, or failure to perform, of its Affiliates under this Agreement.

Technology Transfer. During the [***], Stanford shall update Appendix C to add any additional Technology disclosed to its Office of Technology Licensing by Dr. Matthew Porteus in the form of an amended Appendix C to be signed by both parties. Stanford shall deliver such Technology to Graphite through physical transfer, communications by Dr. Matthew Porteus or members of the Porteus Lab or other means, as may be determined necessary or appropriate. Stanford and Graphite acknowledge and agree that certain of the Technology listed in Appendix C as of the Effective Date may have been disclosed to Graphite prior to the Effective Date by Matthew Porteus or members of the Porteus Lab, including former members [***] employed by Graphite as of the Effective Date. Stanford and Graphite agree that such prior disclosure shall be deemed a disclosure hereunder and shall satisfy the obligations of Stanford hereunder with respect to such Technology.

SUBLICENSING

Permitted Sublicensing.

Graphite may grant Sublicenses, including through multiple tiers, in the Initial Field of Use and Licensed Territory only during the Exclusive term and only if Stanford has not notified Graphite of a breach of its diligence obligations under Section 6.1 or such breach has been cured. Graphite will remain responsible for its obligations under this Agreement, including but not limited to the diligence requirements listed in Appendix A, to the extent such obligations are not fulfilled by Graphite’s Affiliate or a Sublicensee.

Graphite also may grant Sublicenses, including through multiple tiers, in the Rx Field of Use and Licensed Territory. Such Sublicenses may be exclusive as to Graphite but shall only sublicense such non-exclusive rights as Graphite has been granted by Stanford hereunder.

Any Sublicense must be entered into in an arms-length transaction. Graphite will be responsible for the acts or omissions of its Sublicensees in connection with their performance under any Sublicense as though such acts or omissions were those of Graphite under this Agreement. A grant of rights to a Third Party solely to enable such Third Party to perform services on behalf of Graphite or its Affiliate shall not be considered a Sublicense, and such Third Party shall not be considered a Sublicensee solely on account of receiving such grant of rights.

Terms of Nonroyalty Sublicensing Consideration: Nonroyalty Sublicensing Consideration shall be subject to apportionment in the event that the Licensed Patents and Technology are sublicensed along with patents, or other proprietary technology or intellectual property rights owned or controlled by Graphite. In the event that the geographic scope of a Sublicense includes both (a) countries in which there is a Valid Claim that covers a Licensed Product in such countries and (b) countries in which there is no Valid Claim that covers a Licensed Product, then in addition to the foregoing apportionment provision, Nonroyalty Sublicensing Consideration shall be subject to further apportionment to account for the fact that a Valid Claim exists only in certain countries within the geographic scope of such Sublicense taking into account the market size and importance of geographic scope both in terms of (a) where the Licensed Product is being manufactured and (b) where the Licensed Product is being sold. In order to exercise this apportionment, Graphite shall provide Stanford with the total amount of Nonroyalty Sublicensing Consideration received, the proposed apportionment of such amount, and a reasonably detailed written justification for such proposal within forty-five (45) days of execution of such Sublicense. If the parties are unable to come to an agreement on such apportionment to determine the amount used for the basis of calculating Nonroyalty Sublicensing Consideration sharing hereunder, then the determination of such apportionment shall be subject to the Dispute Resolution process as described in Section 17.

Required Sublicensing. Stanford would like licensees to address unmet needs, such as those of neglected patient populations or geographic areas, giving particular attention to improved therapeutics, diagnostics and agricultural technologies for the developing world.

Sublicense Requirements. Any Sublicense:

shall be consistent with the terms of this Agreement;

will require first-tier Sublicensees to provide Graphite with, and require subsequent-tier Sublicensees to provide to the prior-tier Sublicensee, royalty reports containing information sufficient to enable Graphite to fulfill its reporting obligations under Section 8;

will contain disclaimers of representations and warranties on behalf of Stanford, consistent with those set forth in Section 9; and

will contain obligations at least as protective of Stanford as those set forth in Section 10;

will include provisions consistent with the provisions of Section 4.5; and

shall terminate in the event this Agreement terminates in its entirety for any reason; subject to Section 15.5 (Effect of Termination on Sublicenses).

[***] by Sublicensee. Any Sublicense must include provisions that give effect to and are consistent with the following clauses:

In the event Sublicensee [***]:

Sublicensee will [***]; and

Sublicensee will have [***].

Sublicensee shall not have [***].

Sublicensee will provide written notice to Stanford at least [***] prior to [***].

Copy of Sublicenses and Sublicensee Royalty Reports. Graphite will submit to Stanford copies of each Sublicense within 30 days of signing and within thirty 30 days after entering into any subsequent material amendments to any Sublicense, and all copies of Sublicensees’ royalty reports, subject in each case to appropriate redactions of information not necessary to determine compliance with this Agreement.. Beginning with the first Sublicense, Graphite’s Chief Financial Officer or equivalent will certify annually regarding the name and number of then-current Sublicensees.

Sharing of Nonroyalty Sublicensing Consideration. Graphite will pay to Stanford a portion of all Nonroyalty Sublicensing Consideration, as provided below:

For Sublicenses granting rights under the Licensed Patents and Technology in the Sickle Cell Disease Field of Use:

Prior to [***] – [***]%

GOVERNMENT RIGHTS

DILIGENCE

Milestones. Because the invention is not yet commercially viable as of the Effective Date, Graphite, directly or through its Affiliates or Sublicensees, will diligently develop, manufacture, market and sell Licensed Products in each Initial Field of Use. In addition, Graphite will meet the milestones shown in Appendix A, and notify Stanford in writing as each milestone is met.

Progress Report. By March 1 of each year until the First Commercial Sale, Graphite will submit a written annual report to Stanford covering the preceding calendar year. The report will use the template of Appendix D and will include information sufficient to enable Stanford to satisfy applicable reporting requirements of the U.S. Government and CIRM and for Stanford to ascertain progress by Graphite or its Sublicensee toward meeting this Agreement’s diligence requirements. Each report will describe, where relevant: Graphite’s or its Affiliates or Sublicensee’s progress toward commercialization of Licensed Product, including work completed, summary of work-in-progress, current schedule of anticipated events or milestones, market plans for introduction of Licensed Product, and significant corporate transactions involving Licensed Products.

Information Rights. Graphite will deliver to Stanford such financial and other information that Graphite makes available to its other investors, provided that such information shall include, at a minimum:

copies of annual financial statements for Graphite;

any business plans or periodic internal reports of the financial condition of Graphite; and

an annual capitalization table showing each stockholder’s equity holdings in Graphite.

Clinical Trial Notice. Graphite will notify the Stanford University Office of Technology Licensing prior to commencing any clinical trials at Stanford. If Graphite does not notify Stanford University Office of Technology Licensing at least [***] prior to enrolling the first patient in a clinical trial at Stanford, Graphite agrees that it will pay $[***] to Stanford within 30 days of being invoiced.

Failure to Meet Development Milestones. If Graphite believes that, despite using commercially reasonable efforts, it will not achieve a milestone specified in Appendix A within the time period set forth therein, it may notify Stanford in writing in advance of the relevant deadline. Graphite shall include with such notice (a) an explanation of the reason(s) for such failure (“Milestone Explanation”) and (b) a reasonably detailed, written plan for achieving an amended milestone within a reasonable time period thereafter (“Milestone Plan”). If Graphite so notifies Stanford and provides Stanford with a Milestone Explanation and Milestone Plan, but the Milestone Plan is not reasonably acceptable to Stanford, then Stanford shall provide Graphite with a detailed, written explanation as to why the Milestone Plan is not reasonably acceptable and shall provide Graphite with suggestions for a reasonably acceptable Milestone Plan. Graphite shall have an opportunity to provide Stanford with a Milestone Plan reasonably acceptable to Stanford within [***] after receipt of the notice from Stanford described in the previous sentence, during which time Stanford agrees to exercise good faith in working with Graphite to develop a mutually agreeable revised Milestone Plan. If, within such [***] period, Graphite provides Stanford with a Milestone Plan reasonably acceptable to Stanford, then Appendix A shall be amended automatically to incorporate the amended milestone(s) set forth in the Milestone Plan. If, within such [***] period, Graphite fails to provide a Milestone Plan reasonably acceptable to Stanford, then Graphite shall have an additional opportunity to provide Stanford with a Milestone Plan reasonably acceptable to Stanford within [***] after notice of rejection from Stanford, or until the original deadline

FINANCIAL TERMS-

License Issue Fee. Graphite will pay to Stanford a non-creditable, non-refundable license issue fee of $50,000 within thirty (30) days after the execution and delivery of this Agreement by both parties.

Equity Interest. As further consideration, Graphite will grant to Stanford 1,080,262 shares of common stock in Graphite. When issued, those shares will represent [***]% of the common stock in Graphite on a Fully-Diluted Basis as of the closing of the first tranche of Graphite’s Series A preferred stock financing and as reflected in the pro forma capitalization table set forth in Exhibit B. Within [***] unless requested earlier in writing by Stanford, Graphite will provide Stanford with its current capitalization table and the [***]. Graphite will provide Stanford with the [***]. On the 3-month anniversary of the Effective Date, but not before, Graphite will issue [***]% of all shares granted to Stanford pursuant to this Section 7.2 and Section 7.3 directly to and in the name of the inventors or their heirs according to the inventor list that Stanford will provide prior to issuance.

Anti-Dilution Protection. Graphite will issue Stanford, without further consideration, 459,433 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. 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 7.3 will be adjusted to maintain Stanford at [***]% 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 7.3 will continue until an amount of $[***], when aggregated with prior closings, has been raised by Graphite in a bona fide round of financing through the sale of securities or by conversion of instruments convertible into equity (“Dilution Trigger”). If the Dilution Trigger is reached or exceeded during a specific round of funding, Anti-Dilution Protection 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.

Purchase Right.

Definitions. For purposes of this Section 7.4 and Section 7.5:

“Adjustment Event” means the first closing of the sale by Graphite of any series of preferred stock other than Series A Stock.

“Board of Directors” means (i) if Graphite is organized as a corporation, its board of directors, and (ii) if Graphite is organized as a limited liability company, the Graphite manager(s) or member(s) or both that have the power to direct the principal management and activities of Graphite, whether through ownership of voting securities, by agreement, or otherwise.

“Qualifying Offering” means a private offering of Graphite’s equity securities (or securities convertible into or exercisable for Graphite’s equity securities) for cash (or in satisfaction of debt issued for cash) having its final closing on or after the date of this Agreement and which is led by one or more venture capital, professional angel, or corporate or other similar institutional investors that either (i) have the industry expertise to perform appropriate due diligence on the company, its industry and technology and have performed such due diligence, or (ii) have retained an independent consultant with such expertise that has performed due diligence and reported its evaluation of Graphite to the lead investor.    Notwithstanding the foregoing, “Qualifying Offering” shall exclude the sale of Graphite’s Series A preferred stock (“Series A Stock”) pursuant to the terms of a stock purchase agreement in effect as of the Effective Date and under which an initial purchase and sale of shares purchase and sale of Series A Stock has occurred prior to the Effective Date (the “SPA”) unless such sale includes purchasers who did not purchase, and funds under common management with such purchasers did not purchase, shares of Series A Stock in the initial purchase and sale of shares of Series A Stock under the SPA. For the avoidance of doubt, if Graphite is a limited liability company, then “equity securities” means limited liability company interests in Graphite.

“Share” means:

[***]% with respect to any sale of Graphite’s Series A Stock pursuant to the terms of the SPA that includes purchasers who did not purchase, and funds under common management with such purchasers did not purchase, shares of Series A Stock in the initial purchase and sale of shares of Series A Stock under the SPA.

[***]% with respect to any Qualifying Offering having a closing after the final closing of the sale by Graphite of Series A Stock pursuant to the SPA and on or prior to the date of an Adjustment Event; or

with respect to any Qualifying Offering having a closing after the date of an Adjustment Event, the percentage necessary for Stanford and the Osage Parties (as defined below) to maintain their respective pro rata ownership interests in Graphite on a Fully-Diluted Basis; provided, however, that for purposes of this clause (ii), the pro rata ownership interest of the Osage Parties shall be determined taking into account solely such portion of such ownership interest that derives from the exercise by the Osage Parties of the Purchase Right assigned by Stanford to the Osage Parties as provided in Section 7.4(B).

The parties shall construe the term “Fully-Diluted Basis” mutatis mutandis in the case where Graphite is organized as a limited liability company.

Grant of Right; Assignment. Stanford shall have the right, but not the obligation, to purchase for cash up to its Share of the securities issued in any Qualifying Offering on the terms, and subject to the conditions, set forth in this Section 7.4 and Section 7.5 (the “Purchase Right”). Such right is assignable by Stanford to Osage University Partners or any of its affiliated investment funds (each, an “Osage Party” and collectively, the “Osage Parties”). Except to the extent that Stanford assigns its Purchase Right to one or more Osage Parties, no investment by an Osage Party in Graphite shall reduce or otherwise affect Stanford’s right to participate in any Qualifying Offering under this Agreement. For the avoidance of doubt, if Graphite has entered into another Exclusive (Equity) Agreement or other agreement to license intellectual property from Stanford that includes a right equivalent to the Purchase Right, Stanford and the Osage Parties may only exercise their right(s) to purchase all or part of a Share under one agreement.

Termination of Right. The Purchase Right shall terminate as to Stanford and the Osage Parties upon the earliest to occur of the following (each a “Termination Event”):

Immediately prior to the closing of a firm commitment underwritten public offering of Graphite’s common stock;

Immediately prior to the closing of the sale of all or substantially all of Graphite’s assets or voting stock (regardless of the form of transaction and expressly including a merger, combination, or purchase and sale of assets or stock) to a company that has a class of securities publicly traded or covered by an effective registration statement (including a general form for registration of securities or Form 10) under the applicable securities laws of the country of its domicile (including a shell company or other business entity organized primarily for the purpose of acquiring such assets or voting stock, such as a special purpose acquisition corporation or SPAC) for cash, securities of such company, contingent value rights or payments, or any combination thereof; or

Immediately prior to the closing of an acquisition of all or substantially all of Graphite’s assets or voting stock for cash, marketable securities, contingent value rights or payments, or any combination thereof by either:

a private operating company (as opposed to a shell company or other business entity organized primarily for the purpose of acquiring such assets or voting stock); or

an investment firm or other financial buyer in furtherance of a “roll-up” or other investment strategy in Graphite’s current or prospective market(s);

Excluded Issuances. The Purchase Right shall not apply to the issuance of securities: (i) to employees, individuals who are members of Graphite’s Board of Directors as of the time of issuance, and service providers to Graphite pursuant to a plan, agreement or arrangement approved by Graphite’s Board of Directors; (ii) as additional consideration in lending or leasing transactions; (iii) to an entity pursuant to an arrangement that Graphite’s Board of Directors determines in good faith is a strategic partnership or similar arrangement of Graphite (i.e., an arrangement in which the transaction in which such entity purchases securities is not primarily for the purpose of financing Graphite); or (iv) to owners of another entity in connection with the acquisition of that entity by Graphite.

Coordination with Sections 7.2 and 7.3. For the avoidance of doubt: (i) any securities Stanford may acquire or have the right to acquire under Section 7.2 or 7.3 above shall not reduce the number of securities Stanford and the Osage Parties may collectively purchase under this Section 7.4 or under any rights agreement or similar agreement regarding Graphite entered into by Stanford (each, a “Rights Agreement”); and (ii) Stanford shall not be obligated to purchase under this Section 7.4 any Graphite securities it has the right to acquire under Section 7.2 or 7.3 above.

Rights Agreements; Information Rights; Notice; Elections.

Graphite shall ensure that each Rights Agreement to which Stanford is a party will at all times grant it the same rights as all other investors that are parties to that Rights Agreement, including, without limitation: the same right to purchase additional securities in future offerings (but only if Stanford has agreed that such rights supersede the Purchase Right set forth in Section 7.4 and this Section 7.5); the same information rights; the same registration rights as are granted to other parties thereto; and all such rights granted to any investor designated as a “Major Investor” or other similar designation, even if Stanford is not so designated. Notwithstanding the foregoing, this Section 7.5(A) shall not be construed to limit any rights to which Stanford would otherwise be entitled under this Agreement.

Notwithstanding any terms to the contrary contained in any applicable Rights Agreement:

Neither Stanford nor the Osage Parties shall be entitled under any Rights Agreement to representation on the Board of Directors or to attend meetings of the Board of Directors;

In connection with all Qualifying Offerings, Graphite shall give Stanford notice (“Notice”) of the terms of the offering, including: (i) the names of the investors, the allocation of equity and equity-linked securities among them, and the total amounts to be invested by each of them in such offering; (ii) pre- and post- (projected) financing capitalization table; (iii) investor presentation(s) (if any) provided to other investors participating in the offering; and (iv) an introduction to the lead investor in such offering for the purpose of discussing the lead investor’s due diligence process and evaluation of the investment opportunity. During the Notice Period (as defined below), Graphite shall give Stanford such other documents and information as Stanford may reasonably request for the purpose of making an investment decision or verifying the number of units of the equity or equity-linked security it is entitled to purchase in such offering; and

Stanford will have a period of 15 Stanford business days (i.e., days other than Saturdays, Sundays, and holidays or other days on which Stanford is officially closed) after receiving Notice of a Qualifying Offering (the “Notice Period”) to (i) elect to exercise its Purchase Right in whole or in part, (ii) decline to exercise its Purchase Right, or (iii) take no action (in which case Stanford will be deemed to have declined to exercise its Purchase Right). Graphite shall provide Stanford updated information promptly after any substantive information in the Notice becomes inaccurate, regardless of whether Stanford has previously elected or declined to exercise its Purchase Right. If the updated information constitutes a material change from the information included in the original Notice (as it may have been previously updated), a new Notice Period for the Qualifying Offering will commence and Stanford may within 15 Stanford business days from and including the date it received the updated

If Stanford has no information rights under a Rights Agreement and to the extent that such information has been prepared by Graphite for other purposes, so long as Stanford holds Graphite securities, Graphite shall furnish to Stanford, upon request and as promptly as reasonably practicable, Graphite’s annual consolidated financial statements and annual operating plan, including an annual report of the holders of Graphite’s securities, and such other information as Stanford may reasonably request from time to time for the purpose of valuing its interest in Graphite.

Earned Royalties. In addition to the annual license maintenance fee (but subject to any credits permitted under Section 7.6), Graphite will pay Stanford earned royalties on Net Sales as follows:

Earned royalty rate:

Category

Licensed Products covered by a Valid Claim of Licensed Patents (each, a “Patent Licensed Product”)

Licensed Products covered by Technology but not covered by a Valid Claim of Licensed Patents (“Non-Patent Licensed Product”)

Royalty Term: Graphite’s obligation to pay royalties as set forth above shall commence, on a Licensed Product-by-Licensed Product and country-by-country basis on the First Commercial Sale of such Licensed Product in such country and shall expire on the latest to occur of (i) expiration of the last Valid Claim of a Licensed Patent that covers the sale or manufacture of the applicable Licensed Product in such country, (ii) expiration of any period of regulatory exclusivity

Royalty Stacking: In the event Graphite determines it is reasonably necessary for Graphite or its Affiliate or a Sublicensee to obtain a license to patent rights of one or more unaffiliated Third Parties in order to practice for commercial purposes any Licensed Patents or Technology and/or make, have made, use, sell, offer to sell or import Licensed Products, and royalties on Net Sales of a Licensed Product are payable both to Stanford under this Agreement and to the unaffiliated Third Parties under such separate license agreement in order to practice any Licensed Patents or Technology and/or to make, have made, use, sell, offer to sell or import any Licensed Products, then the earned royalty percentage due to Stanford hereunder will be reduced as follows:

Earned Royalty Rate Floor: Notwithstanding any royalty reductions taken above, in no event will the earned royalties payable to Stanford under this Agreement be reduced by more than [***] percent ([***]%) as a result of the reduction described in paragraph (D) in any given payment period.

[***].

Obligation to Pay Earned Royalties. To the extent set forth in this Agreement, an earned royalty is due Stanford under this Agreement for any activity conducted during the Royalty Term under the licenses granted. For convenience’s sake, the amount of that royalty is calculated using Net Sales. Nonetheless, if certain Licensed Products are made, used, imported, or offered for sale before the date this Agreement terminates or expires, and those Licensed Products are sold after the termination or expiration date Graphite and its Sublicensees will pay Stanford an earned royalty for their exercise of rights based on the Net Sales of those Licensed Products. Upon expiration or termination of this agreement, Graphite and its Sublicensees will provide to Stanford an inventory listing of all Licensed Products on hand that were manufactured prior to the expiration or termination date. Graphite and its Sublicensees will be responsible for paying royalties on sales of such Licensed Products in accordance with this Section 7.8.

No Escrow. Graphite shall not pay royalties owed to Stanford hereunder into any escrow or other similar account. Graphite may permit Sublicensees to pay royalties owed to Graphite (which may include those amounts thereof that are then owed by Graphite to Stanford) into an escrow or other similar account.

Currency. Graphite will calculate the royalty on sales in currencies other than U.S. Dollars using the appropriate foreign exchange rate for the currency quoted by the Wall Street Journal on the close of business on the last banking day of each calendar quarter. Graphite will make royalty payments to Stanford in U.S. Dollars.

Non-U.S. Taxes. Graphite will pay all non-U.S. taxes related to royalty payments. These payments are not deductible from any payments due to Stanford.

Interest. Any payments not made when due will bear interest at the lower of (a) [***] or (b) the maximum rate permitted by law.

ROYALTY REPORTS, PAYMENTS, AND ACCOUNTING

Earned Royalty Payment and Report. Beginning with First Commercial Sale by Graphite, its Affiliate or a Sublicensee, or with the first receipt of any Nonroyalty Sublicensing Consideration by Graphite, Graphite will submit to Stanford a written report, an earned royalty payment and/or Nonroyalty Sublicensing Consideration payment due Stanford within [***] after each calendar period, where the period is initially on a per-year basis, and changes to a per-quarter basis when annual earned royalty payments to Stanford exceed $[***]. This report will use the template of Appendix B and will state the number, description, and aggregate Net Sales of Licensed Product during the completed calendar time period and details about any Sublicenses entered into within such calendar time period. The report will include an overview of the process and documents relied upon to permit Stanford to understand how the earned royalties and Nonroyalty Sublicensing Consideration are calculated. With each report, Graphite will include any earned royalty payment and Nonroyalty Sublicensing Consideration payment due Stanford for the completed time period (as calculated under Section 7.8 and Section 4.7). Each report provided pursuant to this Section 8.1 and each milestone payment shall be accompanied by a description, made in good faith by Graphite or other Selling Party, of which Licensed Patents cover the applicable Licensed Product(s).

No Refund. In the event that a validity or non-infringement challenge of a Licensed Patent brought by Graphite is successful, Graphite will have no right to recoup any royalties paid before or during the period challenge.

Termination Report. Graphite will pay to Stanford all applicable royalties and submit to Stanford a written report within [***] after this Agreement terminates or expires. Graphite will continue to submit earned royalty payments and reports to Stanford after this Agreement terminates or expires, until all Licensed Products made or imported under the license, and for which an earned royalty would be due under Section 7.8 have been sold.

Accounting. Graphite will and will cause any Sublicensees to maintain records showing manufacture, importation, sale, and use of a Licensed Product for [***] from the date of sale of that Licensed Product. Records will include general-ledger records showing cash receipts and expenses, and records that include: production records, customers, invoices, serial numbers, and related information in sufficient detail to enable Stanford to determine the royalties payable under this Agreement.

Audit by Stanford. Graphite will allow Stanford to cause an independent auditor reasonably acceptable to Graphite to examine Graphite’s financial records relevant to its payment obligations under this Agreement solely to verify the accuracy of payments made by Graphite under this Agreement. Any such audit shall be conducted upon at least [***] prior written notice, no more than once per calendar year during Graphite’s normal business hours. The auditor shall be subject to the confidentiality obligations of Section 19 and shall provide Graphite with a copy of the audit report at the same time such report is delivered to Stanford. The results of the audit shall be the Confidential Information of Graphite provided Stanford is allowed to use the results internally in any way it deems necessary for its audit purposes.

Paying for Audit. Stanford will pay for any audit done under Section 8.5. But if the audit reveals an underreporting of earned royalties due Stanford of [***] for the period being audited, [***].

EXCLUSIONS AND NEGATION OF WARRANTIES

Negation of Warranties. Stanford provides Graphite the rights granted in this Agreement AS IS and WITH ALL FAULTS. Stanford makes no representations and extends no warranties of any kind, either express or implied. Among other things, Stanford disclaims any express or implied warranty:

of merchantability, of fitness for a particular purpose;

of non-infringement; or

arising out of any course of dealing.

No Representation of Licensed Patent. Graphite also acknowledges that Stanford does not represent or warrant:

the validity or scope of any Licensed Patent or Technology; or

that the exploitation of the Licensed Patents or Technology will be successful.

INDEMNITY

Indemnification. Graphite will indemnify, hold harmless, and defend all Stanford Indemnitees against any Third Party claim of any kind arising out of or related to the exercise by Graphite, its Affiliates or Sublicensees of any rights granted Graphite under this Agreement or the breach of this Agreement by Graphite, except to the extent such Third Party claim results from the gross negligence or willful misconduct of a Stanford Indemnitee. Stanford agrees to inform Graphite promptly in writing of any claim or threatened claim that may give rise to an obligation of indemnity under this Agreement of which Stanford becomes aware. The failure to inform Graphite as described above shall not relieve Graphite of any liability or indemnification obligations hereunder unless Graphite is prejudiced as a result of such failure. Stanford will provide Graphite with the first right to defend and settle and exclusive control of the defense or settlement of each such claim, provided that (a) Graphite must do so in a manner that does not adversely affect Stanford’s interests. (b) it must obtain Stanford’s prior consent to any settlement (such consent not to be unreasonably withheld or delayed), (c) it must select legal counsel reasonably acceptable to Stanford, and (4) the defense activities to be taken by Graphite shall not materially impair the Stanford Indemnitee’s reputation or admit or increase any criminal liability of the Stanford Indemnitees without consent from the affected Stanford Indemnitees.

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 10.1 or for any use by Graphite of the Licensed Patents and 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.

PROSECUTION AND PROTECTION OF PATENTS

Patent Prosecution. Graphite acknowledges that, as of the Effective Date, [***] U.S. patent application serial number [***] claiming the invention disclosed in Stanford Case No. [***], which is included in the Licensed Patents, and [***].

Stanford will be responsible for preparing, filing, prosecuting and maintaining the Licensed Patents in the United States. As long as Graphite is not delinquent on any undisputed, material reimbursement obligation under Section 14.2, Stanford agrees to (i) instruct Stanford’s patent counsel to furnish to Graphite or its designee copies of all documents relevant to such filing, prosecution and maintenance prior to any deadlines and in sufficient time for Graphite to review and comment on such documents, and (ii) allow Graphite a reasonable opportunity to comment on documents to be filed with the United States patent office with respect to the Licensed Patents. Stanford shall reasonably consider any such comments.

As of the Effective Date, [***]. Stanford agrees to (i) furnish to Graphite copies of documents that are relevant to [***], and (ii) will promptly convey to [***].

In the event Graphite decides that it no longer desires to pay for Stanford’s actual costs incurred in the filing, prosecution, or maintenance of one or more Licensed Patents, Graphite shall give Stanford written notice at least [***] in advance of any applicable deadline for that Licensed Patent. Stanford may in its discretion continue to prosecute and maintain such Licensed Patent(s) at its expense, in which case such Licensed Patent(s) will no longer be covered by the license granted under this Agreement. Graphite’s obligation to pay patent expenses for such Licensed Patent(s) will terminate [***] after the date of such notice.

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 Licensed Patents in accordance with Stanford usual practice from Stanford provided Stanford will provide further details if Graphite requests such for a specific invoice, Graphite will reimburse Stanford:

$[***] to offset Licensed Patent’s patenting expenses, including but not limited to interference or reexamination matters, inventorship or ownership disputes and opposition proceedings incurred by Stanford before [***]; and

for all Licensed Patent’s patenting expenses, including but not limited to interference or reexamination matters, inventorship disputes and opposition proceedings, in each case, reasonably incurred by Stanford after [***], 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.

Infringement Procedure. Each party will promptly notify the other if it believes a Third Party infringes a Licensed Patent or if a Third Party files a declaratory judgment action with respect to any Licensed Patent. During the Exclusive Term, Graphite shall have the right to institute a claim or suit against or defend any declaratory judgment action initiated by this Third Party, but only within the Initial Field of Use, as provided in Section 14.4 through and including Section 14.8. Stanford and Graphite agree to consider the rights and interests of any Third party who may have additional license rights or ownership rights to any of the Licensed Patents with regards to the following Sections 14.4 through 14.7.

Graphite Suit. Graphite, itself or through a designee, has the first right to institute and prosecute a suit, or defend any declaratory judgment action relating to the Licensed Patents, but only within the Initial Field of Use

Graphite’s and Stanford’s respective counsel recommend that such action is necessary in their reasonable opinion to achieve standing or a court has required or will require such joinder to pursue the action;

Stanford is not the first named party in the action; and

the pleadings and any public statements about the action state that Graphite is pursuing the action and that Graphite has the right to join Stanford as a party.

Joint Suit. If Stanford and Graphite so agree, they may institute suit or defend the declaratory judgment action jointly. If so, they will:

prosecute the suit in both their names;

each bear their own out-of-pocket costs and expenses;

share any recovery or settlement equally; and

agree how they will exercise control over the action.

Stanford Suit. If Graphite does not initiate an enforcement action within [***] of a request by Stanford to do so or Graphite does not elect to control a declaratory judgment action within [***] of receiving notice that such action has been filed, Stanford has the right to institute and prosecute a suit or defend any declaratory judgment action, and may name Graphite as a party if required for standing purposes. If Stanford decides to institute suit, it will notify Graphite in writing Prior to deciding whether to institute suit, Stanford shall meet with Graphite and consider in good faith Graphite’s comments regarding whether or not to institute a suit. If Graphite does not notify Stanford in writing that it desires to jointly prosecute the suit within [***] after the date of the notice, Graphite will assign and hereby does assign to Stanford all rights, causes of action, and damages resulting from the alleged infringement. Stanford will bear the entire cost of the litigation and will retain the entire amount of any recovery or settlement.

Recovery. Any recovery or settlement received in connection with any suit will first be allocated between the parties to cover the litigation costs each incurred. If such recovery or settlement amount is less than total litigation costs incurred by the parties, in the aggregate, then the amount will be distributed to the parties in proportion to the share of such total litigation costs that was borne by each party. In any suit initiated by Graphite, any recovery in excess of litigation costs will be shared between Graphite and Stanford as follows: i) for any recovery other than amounts paid for willful infringement: (A) Stanford will receive [***] percent ([***]%) of the recovery if Stanford was not a party in the litigation; (B) Stanford will receive [***] percent ([***]%) of the recovery if Stanford was a party in the litigation, or (C) Stanford will receive [***] percent ([***]%) of the recovery if Stanford incurred any litigation costs in connection with the litigation; and (ii) for any recovery for willful infringement, Stanford will receive [***] percent ([***]%) of the recovery; and all other amounts shall be retained by Graphite. In any suit initiated by Stanford, any recovery in excess of litigation costs will belong to Stanford. Stanford and Graphite agree to be bound by all determinations of patent infringement, validity, and enforceability (but no other issue) resolved by any adjudicated judgment in a suit brought in compliance with this Section 14.

Abandonment of Suit. If either Stanford or Graphite commences a suit and then wants to abandon the suit, it will give timely notice to the other party prior to abandoning it. The other party may continue prosecution of the suit after the parties agree on the sharing of expenses and any recovery in the suit.
