If Permitted Subcontractors of Shattuck require any consideration other than fees for service or materials, including royalties or milestone payments for the use of the results of contracted services, Shattuck will promptly so notify in writing and discuss with Ono in good faith actions to be taken. If and when either Party decides to engage a Permitted Subcontractor, such Party will, in advance of such engagement, notify the other Party of such Permitted Subcontractor’s name and address of the principal place of business and facility where activities under the Nonclinical Workplan will be actually performed.

Each Party will keep the other Party reasonably informed as to the progress and results of its activities under the Nonclinical Workplan, in each case through meetings of the JRC occurring at least [***] and as otherwise agreed from time to time, except for day-to-day communication with respect to implementation, progress or results of such activities. In the event a Party reasonably anticipates the delay of its completion of [***] under the Nonclinical Workplan, respectively, such Party will promptly inform the other Party of such anticipated delay, and the Parties will discuss in good faith how to mitigate such delay. Upon completion of all activities conducted by Shattuck as set forth in the Nonclinical Workplan, Shattuck will prepare and provide to Ono a final report detailing the results of all such activities (the “Final Report”).

During the Research Term, Ono will be responsible for its costs and expenses and will pay Shattuck amounts equal to all costs and expenses incurred by Shattuck related to performance of all activities required to complete the Nonclinical Workplan (the “Research Funding” and each payment is a “Research Funding Payment”), including the costs and expenses related to any and all amendments or revisions to the Nonclinical Workplan. The Parties have agreed upon an estimated budget for the activities contemplated under the Nonclinical Workplan (the “Budget”), which amounts they anticipate are sufficient to complete the Nonclinical Workplan.

(a)    Initial Research Funding Payment. Within [***] of Ono’s receipt of an invoice issued by Shattuck after the Effective Date, Ono will make an initial Research Funding Payment to Shattuck in the amount of Three Million, Three Hundred Seventy-Eight Thousand, Three Hundred and Five Dollars ($3,378,305), which amount consists of (i) [***] and (ii) [***], for each of (i) and (ii) as set forth in the Budget (the “Initial Research Funding Payment”).

(b)    Quarterly Research Funding Payments. For Research Funding which is not included in the Initial Research Funding Payment, Shattuck will provide to Ono an updated forecast of quarterly Research Funding for [***] at each JRC meeting. Such forecast will include the summary of each of the total FTE Costs and total Non-Labor Costs estimated for such [***].

From and after the License Effective Date, Ono and its Affiliates and Sublicensees will use Commercially Reasonable Efforts (i) to Develop at least one (1) Product and to undertake investigations and actions required to obtain appropriate Regulatory Approvals necessary to market Product(s) in the Field in the Territory, and (ii) for each country in which Regulatory Approval is obtained, to Commercialize and otherwise Exploit such Products in such country.

(a)Reports. From and after the License Effective Date, within [***] after the end of each Ono Fiscal Year during the License Term, Ono will provide to Shattuck a written report that provides an annual summary of Ono’s (and its Affiliates’ and Sublicensees’) significant activities relating to Research, Development, Manufacture, Commercialization, and other Exploitation of each Product, including the status of Clinical Trials and regulatory activities, including status of applications for Regulatory Approval necessary for marketing of such Products. In addition, if, after the License Effective Date, Ono decides not to continue Research, Development, Manufacture, Commercialization or other Exploitation related to both Development Compounds and any and all related Products thereof by it or through its Affiliates or Sublicensees anywhere in the world (a “Discontinuation Decision”), Ono will provide written notification to Shattuck of such Discontinuation Decision (“Discontinuation Notice”) without delay. In this case, Ono will, within [***] following such Discontinuation Notice, provide Shattuck with [***] (each “Ono Decision Notice”).

(b)    All reports, updates, product complaints and other information provided by the Disclosing Party to the Receiving Party under this Agreement (including under this Section 5.2(a)) will be considered Confidential Information of the Disclosing Party, subject to the terms of Article 9.

Following the License Effective Date, Ono will be responsible, at its sole cost and expense, for Manufacturing or having Manufactured, all materials to enable it to Research, Develop, Commercialize, and otherwise Exploit Products (including as required for any pre-clinical, non- clinical, clinical and commercial use of Products, and including process development and scale- up). In the event Ono elects to Manufacture or have a Permitted Third Party Service Provider Manufacture Development Compounds and/or Products, the Parties will negotiate an appropriate technology transfer agreement whereby Shattuck will (a) provide the (i) Technical Transfer Materials developed pursuant to the Nonclinical Workplan to Ono or its Permitted Third Party Service Provider (to the extent such Technical Transfer Materials exist for a given Development Compound or Product) without any additional costs and (ii) [***], Technical Transfer Materials made at Shattuck's own expenses, for the purpose of enabling Ono to exercise its rights under this Agreement with respect to the Development Compounds and Products, and (b) [***], use Commercially Reasonable Efforts to provide Ono or such Permitted Third Party Service Provider with technical advice and assistance in its use of such Technical Transfer Materials or otherwise in connection with the Manufacture of Development Compounds and Products by Ono or such Permitted Third Party Service Provider. In the event Ono desires to have Shattuck Manufacture Development Compounds or Products for Research, Development, Commercialization or Exploitation of Development Compounds or Products, the Parties will negotiate in good faith a Manufacturing service agreement.

Ono will make the following payments to Shattuck (each, a “Milestone Payment”), in accordance with Section 7.1(d), following achievement of each of the research, clinical, regulatory, and/or commercial milestone events set forth in the tables below (each, a “Milestone Event”).

number of times achieved by one or more Development Compounds. If Ono decides to exercise the Exclusive Option before the achievement of one or more of the research Milestone Events described in this Section 7.1(a), each such unpaid Research Milestone Payment will be paid upon its achievement in accordance with Section 7.1(d)(i). If Ono exercises the Exclusive Option before the achievement of one or more of the research Milestone Events and Ono conducts the activities that trigger the achievement of such research Milestone Event(s), Ono will provide Shattuck with prompt written notice of the occurrence of such event giving rise to such Research Milestone Payment, which will be no later than [***] after the occurrence of such event.

(b)Clinical and Regulatory Milestone Payments.

(i)The Milestone Payments set forth in this Section 7.1(b) will be paid only once, regardless of the number of times each Milestone Event is met for one or more Products. For clarity, Ono will pay Milestone Payments for Milestone Events regardless of whether such Milestone Events are achieved by Ono, its Affiliates or its Sublicensees.

(ii)In the event that Milestone Event No. 3 in the foregoing table is achieved before Milestone Event No. 2 (e.g., [***]), then Ono will make the Milestone Payment associated with Milestone Event No. 2 concurrently with payment of the Milestone Payment associated with Milestone Event No. 3, and no Milestone Payment will be payable with respect to [***]. For clarity, if [***], then the Milestone Payment for [***] will be made upon [***] and the Milestone Payment for [***] will be made upon [***]. Further, if [***], then the Milestone Payment for [***] will be made upon

(iii)In the event a subsequent Milestone Event is achieved before a prior Milestone Event is achieved, then such prior Milestone Payment(s) otherwise payable upon achievement of such prior Milestone Event, to the extent not already paid, will become due and payable at the same time as the Milestone Payment associated with such subsequent Milestone, and no Milestone Payment will be payable with respect to any such prior Milestone Event, as applicable, for a Product. For example, if Milestone Event No. 4 above is achieved but Milestone Event No. 3 has not been achieved yet, then Milestone Payment with respect to Milestone Events No. 3 and No. 4 will be payable (to the extent not already paid) upon the achievement of such Milestone Event No. 4. For clarity, it is agreed by the Parties that each of Milestone Events 4 through 9 is independent and is not necessarily sequential and that this Section 7.1(b)(iii) will not be applicable to Milestone Events 4 through 9.

(c)    Commercial Milestone Payments. For purposes of the commercial Milestone Events set forth in the table below (the “Commercial Milestone Event”), an “[***] Product” is a Product of which [***], and an “[***] Product” is a Product of which [***]. Each Milestone Payment associated with a Commercial Milestone Event may be paid up to twice, once for any [***] Product and once for any [***] Product, provided that the second time a Milestone Payment is triggered, the amount paid will be [***] of the amount paid for the first such Milestone Payment (as depicted below in the fourth column of the table).

The Milestone Payments set forth in this Section 7.1(c) will be paid only once, regardless of the number of times each Milestone Event is met for one or more Products within [***] Product and [***] Product, respectively. For example, in the event the [***] Product first launched in the Territory achieves Commercial Milestone Event No. 1 and another [***] Product subsequently launched in the Territory also achieves Commercial Milestone Event No. 1, then only Commercial Milestone Payment for the first achievement of Commercial Milestone Event No. 1 by first launched [***] Product is payable, and no Commercial Milestone Payment for the achievement of Commercial Milestone Event No. 1 by the subsequently launched [***] Product is payable. For clarity, Ono will pay Milestone Payments for Milestone Events regardless of whether such Milestone Events are achieved by Ono, its Affiliates or its Sublicensees.

(i)With respect to Research Milestone Payments, Shattuck will promptly provide an invoice and taxation documents specified in Section 7.3 for the payment of each Research Milestone Payment following (x) the achievement of the relevant Milestone Event by Shattuck or (y) the receipt of notice from Ono that Ono has achieved a research Milestone Event as specified in Section 7.1(a), and the relevant Research Milestone Payment(s) will be made by Ono to Shattuck within [***] following Ono’s receipt of such invoice issued by Shattuck and taxation documents specified in Section 7.3.

(ii)With respect to Milestone Events set forth in Sections 7.1(b), Ono will provide Shattuck with prompt written notice of the occurrence of any event giving rise to a Milestone Payment, which will be no later than [***] after the occurrence of such event. Thereafter, the relevant Milestone Payment will be made by Ono to Shattuck within [***] following Ono’s receipt of an invoice issued by Shattuck and the taxation documents specified in Section 7.3.

(iii)With respect to Milestone Events set forth in Section 7.1(c), Ono will provide Shattuck with a written notice of the occurrence of any event giving rise to a Milestone Payment within [***] following the end of the Quarter during which a Milestone Event has first occurred. Thereafter, the relevant Milestone Payment will be made by Ono to Shattuck within [***] following Ono’s receipt of an invoice issued by Shattuck and the taxation documents specified in Section 7.3.

(iv)In the case of the Commercial Milestone Payments, if multiple Net Sales thresholds are first reached in the same Ono Fiscal Year, the corresponding Milestone Payments will be made with respect to such Ono Fiscal Year.

(a)    Royalty Payments. For each Product, commencing on the date of First Commercial Sale of such Product in any country or jurisdiction in the Territory, Ono will pay to Shattuck the following royalties based on Net Sales of such Products sold by Ono, its Affiliates and its Sublicensees, on an incremental basis in each Ono Fiscal Year during the Royalty Term, at the following rates (“Royalties”):

(b)    No Valid Claim. Subject to Section 7.2(d), during the Royalty Term, on a country-by-country and Product-by-Product basis, when the Product or its manufacture, use, sale, offer for sale or importation is no longer Covered by a Composition of Matter Claim within the Product Patent Rights in such country or jurisdiction, the Royalties payable with respect to Net Sales of such Product sold by Ono, its Affiliates and its Sublicensees in such country or jurisdiction will be reduced by [***] of the Royalties otherwise owed to Shattuck pursuant to this Section 7.2 (such [***] will be referred to as the “Know-How Royalty”). The Parties hereby acknowledge and agree that the Know-How Royalty will be in consideration of the commercial advantage, Know-How and background information gained from the unpatented Product Know-How, including, without limitation, Shattuck’s Confidential Information and Proprietary Materials and be payable during the Royalty Term.

(c)    Loss of Market Exclusivity. Subject to Section 7.2(d), upon a Biosimilar Product entry in a Quarter in a country or jurisdiction in the Territory, then the Royalties otherwise payable by Ono to Shattuck with respect to such country or jurisdiction pursuant to Section 7.2(a) will be reduced by [***] of the Royalties otherwise owed to Shattuck pursuant to this Section 7.2. For clarity, the reduction to Royalties pursuant to this Section 7.2(c) will continue to apply after a Biosimilar Product is no longer being sold in such country or jurisdiction, other than as a result of a successful infringement suit brought by Ono, its Affiliates or Sublicensees, or by Shattuck or its Affiliates.

(d)    Minimum Royalty Rate. Anything contained in this Agreement to the contrary notwithstanding, none of the reductions to Royalties provided in Sections 7.2(b) or (c), or (e) will, individually or in the aggregate, reduce the Royalties payable with respect to Net Sales of any Product sold by Ono, its Affiliates and its Sublicensees in any country or jurisdiction during the License Term by more than [***] of the Royalties otherwise owed to Shattuck pursuant to Section 7.2(a).

(e)    Third Party Licenses. Subject to Section 7.2(d), if, after the Effective Date, Ono acquires or obtains a license to any Third Party Patent Right which contains [***] that would be infringed by Research, Development,

Commercialization or other Exploitation of a Product or is required by order or judgment of a court in any jurisdiction, then, Ono will have the right to deduct from the Royalties due to Shattuck hereunder with respect to such Product in such country or jurisdiction, an amount equal to [***] of royalties and/or other payments that are attributable to such Product and paid by Ono to such Third Party in such country or jurisdiction in a particular Quarter; provided that, Ono may carry over such payments which are incurred or accrued and are not deducted from Royalties payable to Shattuck in such Quarter, and deduct it from any Royalties that would be payable to Shattuck in any of the [***] subsequent Quarters. For the avoidance of doubt, [***].

(f)    Payments and Royalty Reports. Within [***] following the end of each Quarter commencing with the initial Quarter following the First Commercial Sale of a Product, Ono will furnish to Shattuck a reasonably detailed report (“Royalty Reports”) showing the following information, on a country-by-country and Product-by-Product basis: (A) the gross invoiced amount for each Product during the reporting period sold by Ono or its Affiliates or Sublicensees to the first unrelated Third Party; (B) the deductions taken in calculating Net Sales for each Product during such reporting period and the Net Sales for each such Product; (C) the exchange rates used, if any, in determining the amount due or performing any necessary currency conversion; (D) the Royalties payable with respect to such Net Sales; and (E) any withholding taxes required by Applicable Laws to be paid from such Royalties. Shattuck will issue an invoice for Royalties upon receipt of such Royalty Report, and Ono will pay to Shattuck the Royalties due under this Section

7.2 within [***] following its receipt of such invoice issued by Shattuck and the taxation documents specified in Section 7.3.

(g)    Exchange Rates. For the purpose of calculating Net Sales, Ono will convert any amount expressed in a foreign currency into JPY using its standard conversion methodology consistent with International Financial Reporting Standards. If any currency conversion will be required in connection with Royalties or other reimbursable amounts under this Agreement, such conversion will be calculated using whichever of the following exchange rates (TTS rates) for conversion of JPY into Dollars results in the higher payment to Shattuck: (i) the exchange rate posted by MUFG Bank, Ltd. or (ii) the corporate exchange rate provided by MUFG Bank, Ltd to Ono, in each case (i) and (ii), on the date on which Ono will make the applicable payment. For clarity, Royalties to be paid by Ono to Shattuck will be computed in JPY and will be converted to Dollars in accordance with this Section 7.2(g).

Any withholding or other taxes that a paying Party is required by law to pay or withhold from Royalties or other payments payable to a receiving Party under this Agreement will be deducted from the amount of such Royalties or other payments due, and promptly paid or remitted as appropriate, by the paying Party. Shattuck will provide to Ono any taxation documents and other forms, including taxation documents (Form 3 and Form 17) and the Residency Certificate of

Shattuck issued by the U.S. Internal Revenue Service, that may be reasonably necessary from time to time in order for Ono not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party will cooperate and otherwise take commercially reasonable efforts to obtain any exemptions for or refunds of such withholdings taxes and to minimize any such taxes or withholdings.

Any payments that are not paid on or before the date such payments are due under this Agreement will bear interest from the due date until paid in full at a rate per annum equal to the lesser of (a) [***], as reported by THE WALL STREET JOURNAL, or (b) the highest rate of interest permitted by Applicable Law, and calculated on the number of days such payments are paid after the date such payments are due. Interest will not be compounded. With respect to any payments that are disputed in good faith, no interest will accrue until such dispute is resolved.

All payments required to be made to Shattuck under this Agreement will be made in Dollars by bank wire transfer in immediately available funds to the account listed in Schedule C (or such other account as Shattuck will from time to time advise Ono in writing before such payment is due).

Shattuck and Ono will keep, and require its Affiliates and Sublicensees (in the case of Ono) to keep, complete and accurate books of accounts and records for the purpose of determining the amounts, including Research Funding, payable to Shattuck pursuant to this Agreement. Such books and records will be kept for such period of time required by Applicable Laws, but no less than [***] following the end of the Quarter to which they pertain. Such records will be subject to inspection in accordance with Section 7.7.

At the request of either Shattuck or Ono (“Auditing Party”), and upon at least [***] prior written notice from Auditing Party, but not more than once per Calendar Year, the other Party (“Audited Party”) will permit an independent, reputable, certified public accountant of internationally recognized standing selected by Auditing Party and reasonably acceptable to Audited Party (“Auditor”), at Auditing Party’s sole cost and expense (except as provided in this Section 7.7) during normal business hours, at such place or places where such records are customarily kept, to audit or inspect those books or records required to be kept by Audited Party pursuant to Section 7.6. At Auditing Party’s request, and to the extent not previously reviewed, the Auditor will be entitled to audit the then-preceding [***] of Audited Party’s records solely for purposes of verifying the accuracy of the items contained in the Royalty Reports and Research Funding invoiced by Shattuck. Before beginning the audit, the Auditor will enter into a confidentiality agreement with both Parties containing terms substantially similar to those contained in Article 9. The Auditor will provide a written report to both Shattuck and Ono (at the same time) that will disclose only whether the Royalty payments or Research Funding invoiced by Shattuck were correct and the specific details concerning any discrepancies. The report will

disclose no other information arising from such audit. Inspections conducted under this Section

7.7 will be at the expense of the Auditing Party, unless the audit report discloses that the Royalties payable by Ono or Research Funding invoiced by Shattuck for the audited period were more than [***] of the amount actually paid by Ono as Royalties payment or actual amount of Research Funding Ono owed for such period, in which case Audited Party will pay the reasonable costs and expenses charged by the Auditor. Within [***] following its receipt of the audit report, Ono will pay to Shattuck any underpayment discovered in such audit, together with interest accrued in accordance with Section 7.4. If the Auditor concludes that the Royalties paid or Research Funding invoiced by Shattuck were more than what was owed during the audited period, Ono may deduct the amount of such overpayment from Royalty payments or Research Funding Payments due to be paid to Shattuck in the next Quarter(s) under Article 7, or, if no Royalty payments or Research Funding Payments will be made by Ono for such next Quarter, Ono may invoice Shattuck for such overpayment, and Shattuck will pay such invoice within [***] from the date of its receipt of such invoice. The Auditing Party’s right to audit pursuant to this Section 7.7 will survive for [***] after the effective date of the expiration or termination of this Agreement.

Each Party will, during the Research Term, promptly disclose to the other Party the making, conception or reduction to practice of any and all Product IP within [***] after such Party receives such disclosure from its director, officers, employees or others obligated to assign inventions to such Party or any Affiliate of such Party.

(a)In General. Except as otherwise expressly provided herein, as between the Parties, each Party will own and retain all right, title and interest in and to any and all (i) Know-How, Inventions, Patent Rights and other Intellectual Property rights Controlled by such Party or any of its Affiliates or its or their Sublicensees on the Effective Date, and (ii) Know-How, and other Inventions that are conceived, discovered, developed or otherwise made by or on behalf of such Party (other than by the other Party or its Affiliates) under or in connection with this Agreement, whether or not patented or patentable, and any and all Patent Rights and other Intellectual Property rights with respect thereto.

(b)Joint Inventions. As between the Parties, the Parties will each own an equal, undivided interest in any and all Joint Inventions. Each Party will have the right to Exploit the Joint Inventions, Joint Know-How and practice any Joint Patents without a duty of seeking consent of or accounting to the other Party; provided, however, that each Party may not grant licenses under its interest in Joint Inventions, Joint Know-How and Joint Patents to any Third Party to Research, Develop, Manufacture, Commercialize or otherwise Exploit any Competing Product without obtaining prior written consent of the other Party, provided,

further, that during the License Term, Shattuck may not Exploit the Joint Inventions, Joint Know-How and practice or license any Joint Patents for Researching, Developing, Commercializing, Manufacturing and otherwise Exploiting Products within the Field in the Territory.

(c)U.S. Law. The determination of whether Inventions are conceived, discovered, developed or otherwise made by a Party for the purpose of allocating proprietary rights (including Patent Rights, copyright or other Intellectual Property rights) therein will, for purposes of this Agreement, be made in accordance with Applicable Law in the U.S. as such law exists as of the Effective Date, irrespective of where or when such conception, discovery, development or making occurs.

(a)Prosecuting Party. Each Party will have the first right and authority, but not the obligation, at its sole cost and expense as otherwise specified herein, and in its sole discretion, to Prosecute the Product Patent Rights which are Controlled (except by virtue of the licenses granted in this Agreement) by that Party, on a worldwide basis with patent counsel of its choice (such Party will be referred to as the “Prosecuting Party”). Beginning on the Effective Date, the Prosecuting Party will keep the other Party reasonably informed of all material matters with regard to Prosecution of the Product Patent Rights. The Prosecuting Party will have final authority over all decisions relating to Prosecution of Product Patent Rights which it Controls, but will consider any comments received from the other Party in good faith; provided, however, that, (i) both Parties will discuss in good faith filing strategy and timing with respect to any Product Patent Rights Covering Inventions made, conceived or first reduced to practice in the course of activities under the Nonclinical Workplan (“Research Term Product Patent Rights”), (ii) [***] will have a final decision-making right to such filing strategy of such Research Term Product Patent Rights in the event the Parties fail to reach agreement to such filing strategy, and (iii) [***] will be solely responsible for the costs and expenses, related to the Prosecution of such Research Term Product Patent Rights and will reimburse [***] reasonable costs and expenses, including lawyer fees, related to all Research Term Product Patent Rights. For clarity, [***] will be responsible for the costs and expenses required to Prosecute the Product Patent Rights Controlled by [***] as of the Effective Date, including the matters addressed in Schedule F.

(b)Abandonment. Beginning on the Effective Date, in the event either Party decides to abandon or allow to lapse, or otherwise determines not to Prosecute any of the Product Patent Rights which are Controlled by such Party in any country or region in the Territory (including the cancellation or abandonment of any claim(s) without retaining the right to pursue such subject matter in a separate application, or the failure to file or perfect the filing any claim(s) in any country or region), the first Party will provide reasonable prior written notice to the other Party of such intention (which notice will, to the extent possible, be given no later than [***] prior to the next deadline for any action that must be taken to avoid abandonment

with respect to any such Patent Right) so as to provide the other Party a reasonable amount of time to meet any applicable deadline to establish or preserve such Product Patent Rights in such country or region. In such case, upon written notice to the first Party, the other Party will have the right to assume responsibility for continuing Prosecution of such Product Patent Rights in such country or region at the other Party’s sole expense. The other Party will not become an assignee of the first Party’s interest in such Product Patent Rights as a result of its assumption of such responsibility; provided, however, that in the event Shattuck abandons or allows to lapse, or otherwise does not Prosecute Product Patent Rights which include a Composition of Matter Claim(s) in such country or region and there is no valid Composition of Matter Claim of which Shattuck assumes responsibility for continuing Prosecution in such country or region, Royalties with respect to such country or region will be reduced by [***] in accordance with Section 7.2(b). Upon transfer of the first Party’s responsibility for Prosecuting such Product Patent Rights, the first Party will promptly deliver to the other Party copies of all necessary files related to such Product Patent Rights with respect to which responsibility has been transferred and will take all actions and execute all documents reasonably necessary for the other Party to assume such Prosecution.

(c)Joint Patents. The rights and responsibility for Prosecution of Patent Rights Covering Joint Inventions (“Joint Patents”) will be determined in good faith by the Parties at the time such Joint Invention is developed.

(d)Cooperation in Prosecution. Each Party will provide the other Party all reasonable assistance and cooperation in the Prosecution efforts provided above in this Section 8.3, including providing any necessary powers of attorney and executing any other required documents or instruments for such Prosecution, as well as the further actions as set forth below.

(e)Patent Term Extension. The Parties will each cooperate with one another and will use Commercially Reasonable Efforts to obtain Patent Term Extensions in any country and region with respect to the Patent Rights covering a Product. Each Party will Prosecute Patent Term Extensions with respect to such Patent Rights which it Controls and [***] will Prosecute Patent Term Extensions with respect to Joint Patents and Patent Rights which [***] Controls. [***] will have the final decision-making rights to elect to seek Patent Term Extensions in any country and region with respect to Product Patent Rights and Joint Patents after considering [***] reasonable requests and suggestions with respect to such election. [***] will promptly deliver to [***] copies of all documents necessary for Patent Term Extensions which [***] Prosecutes.

(a)    Notification of Infringement. In the event that either Shattuck or Ono becomes aware that a Third Party is, or may be, infringing any Product Patent Rights, including submission by any Third Party of an application under

Subsection (k) of Section 351 of the PHSA, with respect to a product the manufacture, use, offer for sale, sale or import of which infringes any Product Patent Rights (an “Infringement”), that Party will promptly notify the other Party in writing to that effect (each, an “Infringement Notice”). Any Infringement Notice will include all relevant details, facts and circumstances related to such alleged or threatened Infringement that are known to the reporting Party. In the event the Infringement involves such Third Party’s application under Subsection

(k) of Section 351 of the PHSA, the Parties will act in accordance with Section

8.5. Notwithstanding the foregoing, nothing in this Section 8.4(a) will require Shattuck or Ono to violate any agreements with or confidentiality obligations owed to any Third Party.

(b)    Product Patent Rights. As between the Parties, during the License Term, [***] will have the first right, but not the obligation, to determine the appropriate course of action to enforce the Product Patent Rights or otherwise abate the Infringement thereof, to take (or refrain from taking) appropriate action to enforce the Product Patent Rights, to control any litigation or other enforcement action and to enter into or permit the settlement of any such litigation or other enforcement action with respect to Product Patent Rights. [***] will in good faith consider the interests of [***] in conducting the foregoing activities. [***] will prosecute such action at its own expense and by counsel of its own choice. [***] will render, at [***] expense, all reasonable assistance as requested by [***] in connection with any such action initiated, conducted or prosecuted by [***] , including [***] right to join [***] as plaintiff as necessary for [***] to bring and conduct such action or proceeding and, in case of joining, [***] agrees to give [***] reasonable assistance and authority to file and to prosecute the same. [***] will have the right, at [***] expense, to be represented in any such action by counsel of its own choice, provided that [***] will at all times retain control of such action or proceeding, and [***] and its counsel will reasonably cooperate with [***] and its counsel, if applicable, in strategizing, preparing and presenting any such action or proceeding. If [***] fails to bring an action or proceeding with respect to infringement of any Product Patent Rights as set forth in this Section 8.4(b) within the sooner to occur of (i) [***] following Infringement Notice or (ii) [***] before the time limit, if any, set forth in Applicable Laws for the filing of such actions, [***] will have the right, but not the obligation (i.e., it has the right to indulge such infringement) to bring and control any such action at its own expense and using counsel of its own choice. Upon [***] request, [***] will, at [***] expense, timely join as party-plaintiff in any such litigation and reasonably cooperate with [***] in connection with such infringement action and have the right, at [***] expense, to be represented in any such action by counsel of its own choice, including timely filing such action in [***] name if required. Except as otherwise agreed to by the Parties as part of a cost-sharing arrangement, any recovery or damages realized as a result of such action or proceeding, whether by way of settlement or otherwise, will be used first to reimburse the Parties’ documented out-of-pocket costs and expenses relating to the action or proceeding, and, with respect to any remaining damages relating to the Product (including lost sales or lost profits with respect to the Product), regardless of the Party bringing

suit, such remaining damages will be retained by [***] and deemed Net Sales subject to applicable Milestone Payments set forth in Section 7.1(c) and Royalties payable under Sections 7.2.

(c)    Joint Patents. The rights and responsibility for determining the appropriate course of action to enforce any Joint Patent which does not constitute Product Patent Rights (“Non-Product Specific Joint Patent”) or otherwise abate the Infringement thereof, to take (or refrain from taking) appropriate action to enforce any Non-Product Specific Joint Patent, and to control any litigation or other enforcement action will be determined in good faith by the Parties on a case-by-case basis at the time of such Infringement. The non-controlling Party will reasonably cooperate with the controlling Party in joining as party-plaintiff in any such litigation and provide reasonable assistance as requested by the controlling Party in connection with any such action initiated, conducted or prosecuted by the controlling Party and have the right to be represented in any such action by counsel of its own choice at its own expense. Unless otherwise agreed to by the Parties in writing, all costs and expenses related to such action or proceeding will be shared equally by the Parties. Unless otherwise agreed to by the Parties in writing, all monies recovered upon the final judgment or settlement of any such suit to enforce any such Non-Product Specific Joint Patent will be allocated to compensate each Party for their costs and expenses relating to the action or proceeding, and any remaining amounts will be equally distributed between the Parties.

(d)    Settlement. Neither Party will enter into any settlement or compromise of any action under this Section 8.4 which would in any manner alter, diminish, or be in derogation of the other Party’s rights, including rendering a claim in a Product Patent Right or Non-Product Specific Joint Patent to be invalid or unenforceable under this Agreement without the prior written consent of such other Party, which will not be unreasonably withheld, delayed or conditioned.

(a)    Notice. In the event that either Party (i) receives a copy of an application submitted to the FDA under Subsection (k) of Section 351 of the PHSA (a “Biosimilar Application”) for which a Product is a “reference product,” whether or not such notice or copy is provided under any Applicable Law (including under the BPCIA, the United States Patient Protection and Affordable Care Act or implementing FDA regulations and guidance) applicable to the approval or manufacture of any biosimilar or interchangeable biological product (a “Proposed Biosimilar Product”) in the U.S. or (ii) otherwise becomes aware that such a Biosimilar Application has been filed (such as in an instance described in Section 351(l)(9)(C) of the PHSA) in the U.S., then such Party will promptly provide the other Party with written notice thereof. The terms “reference product” and “biosimilar or interchangeable biological product” will have the respective meanings given to those terms in the BPCIA.

(b)    Access to Confidential Information. Upon written request from [***] and to the extent permitted by Applicable Law, [***] will provide [***] with confidential access to the Biosimilar Application in the U.S. and such other information that describes the process used to manufacture the Proposed Biosimilar Product, in each case, to the extent provided to [***] by the Third Party that submitted the Biosimilar Application (the “Applicant”); provided, however, that prior to receiving the Biosimilar Application and such confidential information, [***] will provide notice to [***] and the Applicant confirming its agreement to be subject to the confidentiality provisions in Section 351(l)(1)(B)(iii) of the PHSA.

As between the Parties, [***] will select and own trademark registrations (to the extent applicable) for all generic names, brand names, logos, trade names and domain names for, or associated with, each Product in the Territory; provided that [***] will not select generic names, brand names, logos, trade names or domain names that are similar to, or confusingly similar to, [***] trademarks (including “Shattuck” and “ARC”) without [***] prior written consent and Shattuck will not select nor register any brand names, logos, trade names or domain names that are the same as, or confusingly similar to, any those selected by [***] for each Product for use with any products of [***]. If requested by [***], the Parties will discuss in good faith the inclusion of a [***] trademark on or in the packaging or labeling of Products. [***] will control the preparation, prosecution and maintenance of trademark applications related to all such generic names, brand names, logos, trade names and domain names in the Territory, at its sole cost and expense and at its sole discretion. As between the Parties, all of the costs, expenses and legal fees in bringing, maintaining and prosecuting any action to maintain, protect or defend any trademark owned by [***] or its Affiliate or Sublicensee hereunder, and any damages or other recovery, will be [***] sole responsibility, and will be taken in its sole discretion.

Each Party agrees that, during the Term of this Agreement and for a period of [***] thereafter, or with respect to Confidential Information which is a Trade Secret, for so long as such information is maintained by the disclosing Party as a trade secret, a Party (the “Receiving Party”) receiving Confidential Information of the other Party (“Disclosing Party”) (or that has received any such Confidential Information from the other Party prior to the Effective Date under the Confidential Disclosure Agreement [***] between Shattuck and Ono (collectively as the “Prior CDA”)) will

(a) maintain in confidence such Confidential Information using not less than the efforts such Receiving Party uses to maintain in confidence its own proprietary industrial information of similar kind and value, but in no event less than a reasonable degree of efforts, (b) not disclose such Confidential Information to any Third Party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted in Section 9.2, and (c) not use such Confidential Information for any purpose except to perform its obligations or exercise its rights under this Agreement.

(a)    The provisions of Section 9.1 will not preclude the Receiving Party from disclosing Confidential Information of the Disclosing Party to the extent (and only to the extent) such disclosure is reasonably necessary in the following instances:

(i)to the extent disclosure of such Confidential Information is reasonably necessary to Prosecute Product Patent Rights and Non-Product Specific Joint Patents, or to file, prosecute or defend litigation relating to Product Patent Rights and Non-Product Specific Joint Patents;

(ii)disclosure to the Regulatory Authorities or other Governmental Entities to the extent that such disclosure is reasonably necessary to obtain Regulatory Approvals, including but not limited to, authorizations to conduct the Clinical Trials with, and to commercially market the Product;

(iii)disclosure to the Receiving Party’s Affiliates and Receiving Party’s or its Affiliates’ respective directors, officers, employees, agents, consultants, attorneys, accountants and potential or actual Sublicensees and Permitted Subcontractors, Permitted Third Party Service Providers or clinical investigators, who need to know the Confidential Information to enable the Receiving Party to exercise its rights or to carry out its obligations under this Agreement (provided that such disclosure will be made only to persons who are bound by confidentiality obligations as least as stringent as those described in this Article 9; provided further that, regarding consultants, Permitted Subcontractors, Permitted Third Party Service Providers and clinical investigators, the duration of their confidentiality and non-use obligation specified in the agreements between them and the Receiving Party may be less than the duration for confidentiality and non- use obligation in this Agreement so long as such agreements specify a duration for confidentiality and non-use obligation at least [***] from the expiration or termination of such agreements;

(iv)disclosure by Shattuck to Third Parties of Intellectual Property rights developed under this Agreement and that solely relate to Shattuck’s background technology generally (provided that such disclosure will be made only to persons who are bound by confidentiality obligations as least as stringent as those described in this Article 9);

(v)if required to be disclosed by Applicable Law or court order or arbitral tribunal order, provided that (a) notice is promptly delivered to the Disclosing Party to the extent practicable, in order to provide the Disclosing Party with an opportunity to challenge or limit the disclosure obligations, (b) the Receiving Party only discloses minimum Confidential Information of the Disclosing Party required to be disclosed in order to comply and (c) the Receiving Party uses reasonable endeavors to assist the

(a)    Following execution of this Agreement, the Parties may issue a press release announcing the existence of this Agreement, and the content and timing of such press release will be subject to the written approval of both Parties. Subject to Section 9.3(b), (c) and (d), each Party agrees not to issue any other press release or other public statement disclosing additional information with respect to this Agreement, or use the name or trademark of the other Party or any of its directors, officers and employees, in either case, without the prior written consent of the other Party. Each Party will be entitled to include the name, logo and picture of the other Party within a list of collaborators with consent of the other Party. Once a Party obtains such consent from the other Party, such Party may use the name, logo and picture of such other Party in a Party’s annual report, company brochure or website and so on, and such Party may continue to use them in the same during the Term.

(b)    After the initial press release under Section 9.3(a), in the event that either Party desires to issue a press release or other public statement relating to this Agreement, the Parties will discuss in good faith and agree upon the contents and timing of such press release or public statement; provided, however, that a Party may, once a press release or other public statement has been made by a Party in accordance with this Agreement, make subsequent public disclosure of any of the information contained in such press release or other public statement, without the approval of the other Party. Notwithstanding the foregoing, after the License Effective Date, Ono may, upon prior written notice to Shattuck, issue a press release or make a public statement relating to Ono’s Research, Development, Manufacture, Commercialization or other Exploitation of the Products in accordance with this Agreement, provided that such press release or public statement does not disclose any Confidential Information of Shattuck. Ono will provide Shattuck with the draft of such press release or public statement reasonably in advance of such press release or public statement for Shattuck’s review. Shattuck will have the right to propose modifications to such press release or public statement for patent reasons or Trade Secret reasons, and Ono will remove all Confidential Information of Shattuck if requested by Shattuck. Either Party may issue a full translation of a press release or public statement to be issued by the other Party.

(c)    Notwithstanding Section 9.3(b), each Party may issue such press release or make such a public statement without obtaining the prior written consent from or prior written notice to the other Party if, in the reasonable judgment of the first Party, such press release or public statement without obtaining the other Party’s consent or prior notice to the other Party is required by Applicable Laws,

provided that the first Party will immediately notify the other Party of its intention to make a press release or public statement when it becomes aware of the necessity of such disclosure under Applicable Laws and provide the other Party with a copy of such press release or other public statement no later than when it is issued or released.

(d)    Without limiting the generality of Section 9.3(a), if either Party proposes to file with the SEC or the securities regulators of any state or other jurisdiction a registration statement or any other disclosure document that describes or refers to the terms and conditions of this Agreement under the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, or any other applicable securities law, such Party will notify the other Party of such intention and will provide such other Party with a copy of relevant portions of the proposed filing within a reasonable time (but at least [***]) prior to such filing (and any material revisions to such portions of the proposed filing within a reasonable time (but at least [***]) prior to the filing thereof), including any exhibits thereto disclosing terms or conditions of this Agreement, and will use reasonable and diligent efforts to obtain confidential treatment of the terms and conditions of this Agreement that such other Party requests be kept confidential, and will only disclose such terms and conditions of this Agreement that it is advised by counsel are legally required to be disclosed. No such notice will be required under this Section 9.3(d) if the description of or reference to this Agreement contained in the proposed filing has been included in any previous filing made by the other Party hereunder or otherwise approved by the other Party.

(a)    A Party may disclose this Agreement and the terms hereof to its existing directors, officers, employees, and Affiliates, provided that such Persons agree to be bound by written confidentiality agreements at least as restrictive as those set forth in this Article 9, and the Party who makes such disclosure to them will be responsible for the breach of such confidentiality obligation by them.

(b)    Ono may disclose this Agreement and the terms hereof to potential or actual Sublicensees and Permitted Third Party Service Providers.

(c)Subject to compliance with the terms and procedures set forth in this Section 9.4(c), a Party may disclose this Agreement and the terms hereof to bona fide prospective investors, grant-making institutions, merger partners, strategic partners or acquirers and their respective professional advisors (collectively, “Prospective Investors”) in connection with the negotiation, entry into and/or performance of a business transaction between such parties, including the conduct of due diligence involved in such transaction, provided that in each case such Prospective Investors agree to be bound by (i) written confidentiality agreements at least as restrictive as those set forth in this Article 9, or (ii) with respect to attorneys, applicable ethical obligations. With respect to Prospective Investors that are engaged in due diligence prior to such Prospective Investors reaching

mutual agreement with the disclosing Party on all material terms of a transaction in a term sheet or letter of intent, the disclosing Party may disclose to the Prospective Investor a redacted version of this Agreement, which the Parties will agree to in good faith within [***] following the Effective Date; provided that such redacted version of this Agreement will not divulge or otherwise make available: (x) the identity of the non-disclosing Party or any of its Affiliates or (y) any of the specific financial terms hereof, except, in each case, to the extent such information has been previously publicly disclosed or the non-disclosing Party consents in writing to such disclosure. With respect to Prospective Investors that are reaching mutual agreement with the disclosing Party on all material terms of a transaction in a term sheet or letter of intent and involved in final due diligence at a status in the negotiations at which the disclosing Party reasonably believes, acting in good faith, that the signing of a definitive agreement governing the transaction is reasonably likely to occur within [***] of such disclosure, the disclosing Party may disclose an unredacted version of this Agreement to such Prospective Investor.

The Parties acknowledge that while scientific publications and presentations regarding results of Research, Development and Exploitation of Products by a Party is beneficial to both Parties, such scientific publications and presentations must be strictly monitored to prevent any adverse effect from premature publication or dissemination of results of the activities hereunder. Each Party agrees that, except as required by Applicable Law, it will not publish or present, or permit to be published or presented, the Confidential Information of the other Party, without the prior written approval of the other Party. Subject to the foregoing, each Party will provide the other Party with the opportunity to review each of the submitting Party’s proposed abstracts, manuscripts or presentations (including information to be presented verbally) that relate to the subject Confidential Information at least [***] prior to its intended presentation or submission for publication, and such submitting Party agrees, upon written request from the other Party given within such [***] period, not to submit such abstract or manuscript for publication or to make such presentation until the other Party is given up to [***] (or such other period as the Parties may mutually agree) from the date of such written request to seek appropriate patent protection for any unpatented technology disclosed in such publication or presentation that it reasonably believes may be patentable. The publishing Party will take into account the reasonable comments or changes proposed by the other Party on any publication or presentation. Once such abstracts, manuscripts or presentations have been reviewed and, where applicable, approved by each Party, the same abstracts, manuscripts or presentations do not have to be provided again to the other Party for review for a later submission for publication. Each Party also will have the right to require that any of its Confidential Information that is disclosed in any such proposed publication or presentation be deleted prior to such publication or presentation. In any permitted publication or presentation by a Party, the other Party’s contribution will be duly recognized, and co-authorship will be determined in accordance with customary industry standards. Notwithstanding the foregoing, during the Research Term, neither Party will publish nor present, nor permit to be published or presented, results of the Nonclinical Workplan, including the Product IP.

The Receiving Party hereby agrees that the unauthorized disclosure of the Confidential Information by the Receiving Party may cause irreparable harm to the Disclosing Party, and that any breach hereof by the Receiving Party may entitle the Disclosing Party to injunctive or equitable relief, in addition to any other legal remedies available to any of them, in any competent jurisdiction.

As to the subject matter of this Agreement, this Article 9 supersedes the Prior CDA. Any confidential information of a Party disclosed under the Prior CDA will be treated as Confidential Information of such Party hereunder, subject to the terms of this Article 9.

The term of this Agreement commences on the Effective Date and, unless earlier terminated pursuant to the provisions of this Article 10, will expire on the last day of the Research Term; provided, however, that if Ono exercises the Exclusive Option provided the License Conditions are timely fulfilled in accordance with Section 2.5(c), then the term will continue until the expiration of the License Term on any Product-by-Product and country-by-county basis (collectively, the “Term”). After the expiration of this Agreement on any Product-by-Product and country-by-country basis, in the Territory, the licenses granted under Article 4 hereof will become a fully paid-up, non-exclusive, perpetual, irrevocable license, with the right to grant and authorize sublicenses without restriction, with respect to such Product in the Field in such country.

This Agreement may be terminated on a Product-by-Product and country-by-country basis or in its entirety prior to the expiration of the Term by either Party in the event of (a), (b) or (c) below, by Shattuck in the event of (d) below, or by Ono in the event of (e) below:

(a)an unremedied material breach by the other Party or the other Party’s Affiliates, in accordance with the provisions of Section 10.3;

(c)upon the bankruptcy or insolvency of, or the filing of an action to commence insolvency proceedings against, the other Party, or the making or seeking to make or arrange an assignment for the benefit of creditors of the other Party, or the initiation of proceedings in voluntary or involuntary bankruptcy, or the appointment of a receiver or trustee of the other Party’s property, in each case that is not discharged within [***];

(d)after the License Effective Date, if Shattuck provides [***] prior written notice to Ono of its decision to terminate this Agreement in its entirety when Ono does not provide Shattuck Ono Decision Notice within the specified period set forth in Section 5.2(a); or

(e)at any time, if Ono provides [***] prior written notice to Shattuck of its decision to terminate this Agreement in its entirety.

(a)Upon a material breach of a representation, warranty, or a material obligation of this Agreement by a Party or its Affiliates (in such capacity, the “Breaching Party”), the other Party (in such capacity, the “Non-Breaching Party”) may provide written notice (a “Breach Notice”) to the Breaching Party specifying the material breach in sufficient detail to put the Breaching Party on notice and clearly state the Non-Breaching Party’s intent to terminate this Agreement if such material breach is not cured.

(b)If the Breaching Party fails to cure such material breach during the [***] period following the date on which the Non-Breaching Party receives the Breach Notice, then this Agreement will terminate on a Product-by-Product and country-by- country basis. In the case a Party who is asserted to have breached a material obligation hereunder, objects to such material breach and initiates dispute resolution pursuant to Section 13.4, whereupon the [***] cure period will be tolled until the dispute is resolved. With respect to Ono’s material payment obligations, including payment for the License Fee under Section 2.5(c), the [***] cure period is replaced to [***], provided, however, that in any event if the License Fee is not paid within [***] following Ono’s receipt of the invoice for the License Fee and the relevant taxation documents required in Section 7.3, Shattuck will have the right to terminate this Agreement and such [***] will not be tolled

for dispute resolution. In the case that (i) the material breach in question takes place with respect only to a certain country within the Territory or a certain Product and (ii) such material breach does not jeopardize or adversely affect Non- Breaching Party’s rights and benefits in and to other country(ies) and other Product, Non-Breaching Party’s right to terminate this Agreement will be limited to such Product in such country.

All licenses (and to the extent applicable, rights) granted under or pursuant to this Agreement are, and will otherwise be deemed to be, for purposes of Section 365(n) of 11 U.S.C. Section 101, et. seq. (“Bankruptcy Code”), licenses of rights to “intellectual property” as defined under the Paragraph 101(35A) of the U.S. Bankruptcy Code. The Parties agree that the non-bankrupt Party will retain and may fully exercise all of its rights and elections under Applicable Law. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against a bankrupt Party, the other Party will be entitled to a complete duplicate of (or complete access to, as appropriate) any Intellectual Property Controlled by the bankrupt Party which at that date is known to be useful or necessary for the Research, Development, Manufacture, Commercialization or other Exploitation of Products throughout the Territory and all embodiments of such Intellectual Property; and the same, if not already in the other Party’s possession, will be promptly delivered to the other Party (a) upon any such commencement of a bankruptcy proceeding, upon the other Party’s written request therefor, unless the bankrupt Party (or trustee on behalf of the bankrupt Party) elects within [***] to continue to perform all of its obligations under this Agreement or, (b) if not delivered under Section 10.4 above, upon rejection of this Agreement by or on behalf of the bankrupt Party, upon written request therefor by the other Party.

(a)If this Agreement is terminated by Shattuck under Section 10.2(a), (c), or (d), or by Ono under Section 10.2(e), or terminated by either Party under Section 10.2(b), then without limiting any other rights of the Parties, on a country-by country and Product-by-Product basis or in its entirety, as applicable:

(i)the rights and privileges granted to Ono under Articles 2, 3, 4, and 8 and Sections 5.1 and 5.2, including the Exclusive Option and the license rights described in Article 4, will immediately terminate as of the effective date of the termination with respect to a terminated Product in a terminated country or in its entirety;

(ii)when this Agreement is terminated entirely, Ono will promptly return or destroy all Confidential Information and Proprietary Materials of Shattuck; provided, however, that Ono may retain, subject to Article 9, (a) one (1) copy of the Confidential Information of Shattuck in its archives solely for the purpose of establishing the contents thereof and ensuring compliance with its obligations hereunder, (b) any Confidential

Information of Shattuck contained in its laboratory notebooks or databases and (c) any computer records or files containing such Confidential Information that have been created solely by its automatic archiving and back-up procedures, to the extent created and retained in a manner consistent with its standard archiving and back-up procedures, but not for any other uses or purposes;

(iii)when this Agreement is terminated entirely, upon such termination in case of termination by Shattuck under Section 10.2(a), (c), or (d), or upon the provision of a termination notice by Ono in the case of termination by Ono under Sections 10.2(e), or termination under Section 10.2(b), the Parties will, at Shattuck’s option and to the extent permitted by Applicable Law, either wind-down any ongoing Clinical Trials relating to the Products or transition responsibility for such ongoing Clinical Trials to Shattuck, each in an orderly fashion (which will include transferring to Shattuck all Product Manufactured for clinical supply at (i) Ono’s cost of manufacturing for such Product or (ii) actual price paid by Ono to its Third Party manufacturer for such supply, as applicable) and with due regard for patient safety and the rights of any patients that are participants in such Clinical Trials, and each Party will take all actions it deems reasonably necessary or appropriate to avoid any human health or safety problems, in compliance with all Applicable Laws in a timely manner, and all costs and expenses incurred from the effective date of the termination notice during the period within which activities are being transitioned or wound down will be borne by Ono;

(iv)if the termination of this Agreement for an entire Product on a worldwide basis occurs after the first Commercial Sale of the applicable Product, Ono will, upon Shattuck’s written request, transfer to Shattuck any inventory of the Product owned or controlled by Ono or its Affiliates as of the termination date at (i) Ono’s cost of manufacturing for such Product or (ii) the actual price paid by Ono to its Third Party manufacturer for such supply, as applicable. If Shattuck does not require Ono to transfer such inventory, Ono will have the right to continue to sell such Product in the Territory for [***] from the termination date of this Agreement;

(v)Ono and its Affiliates will, to the extent permitted by Applicable Law and only with respect to the terminated Product and terminated country(ies), promptly (a) transfer and assign to Shattuck or its designee any and all Regulatory Filings (including Regulatory Approvals) and all trademarks solely related to the Products, and (b) provide to Shattuck the Technical Transfer Materials. To the extent required to enable Shattuck to Research, Develop, Manufacture, Commercialize and otherwise Exploit the Products, Ono will, at Shattuck’s cost for any reasonable and verifiable time (at a mutually agreeable rate) and expense, provide such technical assistance as Shattuck may reasonably request for [***] from the effective date of termination;

(vi)Shattuck will have a fully paid up, non-exclusive, royalty free, irrevocable, sublicensable right and license to all of Ono’s interest in any and all Product Know-How and Product Patent Rights in the terminated Territory for the purpose of Researching, Developing, Manufacturing, Commercializing and otherwise Exploiting Products. If Shattuck desires to have an exclusive license to any of Ono’s interest in any Product Know- How or Product Patent Rights, the Parties will negotiate the terms of such license in good faith. Shattuck will solely control Prosecution and enforcement of all Product Patent Rights, and the Parties will work together in good faith to transfer responsibility for and control of all Prosecution and enforcement activities related to Product Patent Rights to Shattuck, taking into account upcoming deadlines within such Prosecution or enforcement activities. Upon transfer of Ono’s responsibility for Prosecuting such Product Patent Rights, Ono will promptly deliver to Shattuck copies of all necessary files related to such Product Patent Rights with respect to which responsibility has been transferred and will take all actions and execute all documents reasonably necessary for Shattuck to assume such Prosecution;

(vii)the Parties will negotiate in good faith the terms of a non-exclusive, worldwide, royalty-bearing, sublicensable license under any Intellectual Property Controlled by Ono or its Affiliates (which is not included in the Product Know-How or Product Patent Rights) that is necessary or useful for the Research, Development, Manufacture, Commercialization or other Exploitation of the Products but not solely related to the Products and utilized by Ono with respect to the Research, Development, Manufacture, Commercialization, and Exploitation activities related to the Products prior to termination of this Agreement, in each case for the limited purpose of Researching, Developing, Manufacturing, Commercializing and otherwise Exploiting Products.

(b)    If, during the Research Term, Shattuck terminates this Agreement pursuant to Section 10.2(a), the Parties terminate this Agreement pursuant to Section 10.2(b), or Ono terminates this Agreement pursuant to Section 10.2(e), (i) Ono will pay Shattuck for all FTE Costs and Non-Labor Costs incurred by Shattuck up to the effective date of termination and non-cancelable Non-Labor Costs incurred by Shattuck outstanding as of the effective date of termination, and

(ii) Shattuck will refund the unexpended FTE Costs to Ono.

(c)    Notwithstanding the foregoing or anything in this Agreement to the contrary, unless Shattuck specifies in writing to the contrary, no such termination of this Agreement will be construed as a termination of any valid sublicense to any Sublicensee, and thereafter each such Sublicensee will be considered a direct licensee of Shattuck, provided that such Sublicensee is then in full compliance with all terms and conditions of its sublicense and such Sublicensee agrees no later than [***] after the effective date of such termination to assume all obligations of Ono under this Agreement and the sublicense with such

(a)    If this Agreement is terminated by Ono under Section 10.2(a) or (c), then without limiting any other rights of Ono, on a country-by country and Product-by- Product basis or in its entirety, as applicable:

(i)the rights and privileges granted to Shattuck under Articles 2, 3 and 8 will immediately terminate as of the effective date of the termination;

(ii)the license granted by Shattuck to Ono and its Affiliates pursuant to Section 4.1 will survive, subject to Ono’s continued payment of all Milestone Payments, Royalties and other payments under and in accordance with this Agreement with respect to each Product, provided that, in the event that this Agreement is terminated by Ono under Section 10.2(a) or (c), Ono will only be obligated to pay to Shattuck [***] of each Milestone Payment and Royalty payment otherwise due from and after the date of termination. For clarity, this reduction is not the sole remedy under this Agreement and all other remedies will remain available to Ono; and

(iii)when this Agreement is terminated entirely, Shattuck will promptly return or destroy all Confidential Information and Proprietary Materials of Ono, provided that Shattuck may retain, subject to Article 9 hereof, (a) one (1) copy of the Confidential Information of Ono in its archives for the purpose of establishing the contents thereof and ensuring compliance with its obligations hereunder, (b) any Confidential Information of Ono contained in its laboratory notebooks or databases, and (c) any computer records or files containing such Confidential Information that have been created solely by its automatic archiving and back-up procedures, to the extent created and maintained in a manner consistent with its standard archiving and back-up procedures, but not for any other uses or purposes.

(iv)Notwithstanding the foregoing and subject to Article 9 hereof, Ono may retain and use Shattuck’s Confidential Information and Proprietary Materials for the limited purpose of Researching, Developing, Manufacturing, Commercializing and otherwise Exploiting Products in connection with the exercise of its rights set forth in Section 10.6(a)(ii).

Such Senior Executives will endeavor to resolve such Dispute through good faith negotiations for a period of [***] following such written notice.

Subject to Section 9.6, all Disputes which are not resolved between the Senior Executives within such [***] period under Section 13.3 will be finally settled by arbitration under the Rules of Arbitration of the International Chamber of Commerce by three (3) arbitrators appointed in accordance with the said Rules. The place of arbitration will be New York City, New York, United States, if arbitration is demanded by Ono, and will be Osaka, Japan, if demanded by Shattuck. The language of the arbitration will be English. Each Party will nominate one arbitrator, and the two arbitrators so nominated will nominate a third arbitrator, who will act as the chairperson. If the tribunal orders production of documents, the tribunal will take guidance from the IBA Rules on the Taking of Evidence in International Arbitration as current on the date of the commencement of the arbitration. The existence and content of the arbitral proceedings, any information exchanged between Parties during the arbitral proceedings and any rulings or awards will be kept confidential by the Parties and members of the tribunal except (a) to the extent that disclosure may be required by a Party to fulfill a legal duty, protect or pursue a legal right, or enforce or challenge an award in bona fide legal proceedings before a court or other judicial authority, (b) with the consent of both Parties, (c) where needed for the preparation or presentation of a claim or defense in this arbitration, (d) where such information is already in the public domain other than as a result of a breach of this clause, or (e) by order of the tribunal upon application of a Party. The costs and expenses of translation of relevant documents and translators relating to the arbitration will be deemed as the costs and expenses of the arbitration and may be allocated to any Party in the award by the tribunal. The tribunal may include in its award an allocation to any Party of costs and expenses relating to the arbitration, excluding lawyers’ fees, as the tribunal deems reasonable. Each Party will bear its own costs and expenses

for its own lawyers. The award rendered by the tribunal will be final and binding upon the Parties and may be entered in any court of appropriate jurisdiction. The Emergency Arbitrator Provisions and the Expedited Procedure Provisions will not apply.

In the event that an obligation to be performed under this Agreement falls due on a day that is not a Business Day of the Party who owes such obligation, the obligation will be deemed due on the next Business Day of such Party thereafter.

Any consent, notice and communication required or permitted to be given or made hereunder by either Party to the other Party will be in writing and in English.

Notwithstanding set forth in this Section 13.6, it is understood and agreed between the Parties that this Section 13.6 is not intended to govern the day-to-day communications, including invoicing, necessary between the Parties in performing their duties, in due course, under the terms and conditions hereof, and Parties may use other ways to contact the other Party in relation to day-to-day operations.

No failure or omission by either Party in the performance of any obligation of this Agreement will be deemed a breach of this Agreement or create any liability if the same arises from any cause or causes beyond the reasonable control of such Party, including the following: acts of God, fire, storm, flood, earthquake, tsunami, typhoon, explosion, pandemic or other health emergency, acts of war (whether declared or not), rebellion, insurrection, riot, terrorism and civil unrest, and embargoes, power shortage or failure, strikes, lockouts or other labor disturbances, or nonfeasance, omissions, delays or changes in acting by any Governmental Entity or equivalent

(including but not limited to nonfeasance or delays in governmental approval or changes in rules, beyond the reasonable control of the affected Party); provided that the affected Party promptly

notifies the other Party in writing and further provided that the affected Party will use its Commercially Reasonable Efforts (as applicable) to avoid or remove such causes of non- performance and to mitigate the effect of such occurrence, and will continue performance with the utmost dispatch whenever such causes are removed.

It is understood and agreed that the relationship between the Parties is that of independent contractors, that the relationship between the Parties will not constitute a partnership, joint venture, employment or agency, and that nothing in this Agreement will be construed as authorization for either Shattuck or Ono to act as agent for the other. Neither Party will have any express or implied right or authority to assume or create any obligations on behalf of, or in the name of, the other Party, or to bind the other Party to any contract, agreement or undertaking with any Third Party.

This Agreement has been prepared jointly and will not be strictly construed against either Party.

No failure on the part of Shattuck or Ono to exercise, and no delay in exercising, any right, power, remedy or privilege under this Agreement, or provided by statute or at law or in equity or otherwise, will impair, prejudice or constitute a waiver of any such right, power, remedy or privilege or be construed as a waiver of any breach of this Agreement or as an acquiescence therein, nor will any single or partial exercise of any such right, power, remedy or privilege preclude any other or further exercise thereof or the exercise of any other right, power, remedy or privilege. No consent or waiver, expressed or implied, by a Party to the performance by the other Party or of any breach or default by the other Party of its obligations hereunder will be deemed or construed to be a consent or waiver to or of any other breach or default in the performance by such other Party of the same or any other obligations of such other Party hereunder. In any event no waiver will be effective for any purpose hereunder unless such waiver is made in writing and signed by duly authorized signatories of the Party granting such waiver.

If any one or more of the provisions of this Agreement is held to be invalid, illegal or unenforceable, the provision will be considered severed from this Agreement and will not serve to invalidate any remaining provisions hereof, unless the invalid, illegal or unenforceable provision is of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid, illegal or unenforceable provision. The Parties will make a good faith effort to replace any invalid, illegal or unenforceable provision with a valid, legal and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.

This Agreement and any amendment hereto may be executed in counterparts, each of which counterparts, when so executed and delivered, will be deemed to be an original, and all of which counterparts, taken together, will constitute one and the same instrument. For purposes of execution, a copy of this Agreement or any amendment hereto will be deemed an original (including a printed copy of a PDF file delivered via email).

As of the Effective Date, this Agreement will be binding upon and inure to the benefit of the Parties and their respective permitted successors and permitted assigns. Except as set forth in Article 12, no Person other than Ono, Shattuck and their respective permitted successors and assigns hereunder will be deemed an intended beneficiary hereunder, nor have any right to enforce any obligation of any Party to this Agreement, nor will any Person other than Ono and Shattuck and their respective permitted successors and assigns have any obligations to any Party under this Agreement.
