7.5(c) to 7.5(e) (the “Royalty Floor”). Credits for deductions not exhausted in any Calendar Quarter may be carried forward into future Calendar Quarters, provided that such carried forward credits never reduce the royalties due to Biocytogen in any Calendar Quarter below the Royalty Floor.

Article VIII.

PAYMENT; RECORDS; AUDITS

8.1

Payment; Reports. Royalty payments due by Ideaya to Biocytogen under Section 7.5 shall be calculated and reported for each Calendar Quarter. Ideaya shall pay all royalty payments due under Section 7.5 within [***] after the end of each Calendar Quarter and shall include with each payment a report setting forth, on a country-by-country and Licensed Product–by–Licensed Product basis, [***].

8.2

Exchange Rate; Manner and Place of Payment. All references to dollars and “$” in this Agreement shall refer to U.S. dollars. All payments under this Agreement shall be payable in U.S. dollars. When conversion of payments from any currency other than U.S. dollars is required, such conversion shall be at an exchange rate equal to the weighted average of the rates of exchange for the currency of the country from which such payments are payable as published by The Wall Street Journal, Eastern U.S. Edition, during the Calendar Quarter in which the applicable sales were made. All payments owed under this Agreement shall be made by wire transfer in immediately available funds to a bank and an account designated in writing by Biocytogen.

8.3

Taxes.

(a)

Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of such Party under this Agreement.

(b)

Withholding Tax. The Parties agree to cooperate with one another and use reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Ideaya to Biocytogen under this Agreement. To the extent Ideaya is required to deduct and withhold taxes on any payment to Biocytogen, Ideaya shall deduct those taxes from such payment, pay the amounts of such taxes to the proper Governmental Authority in a timely manner, and promptly transmit to Biocytogen an official tax certificate or other evidence of such withholding sufficient to enable Biocytogen to claim such payment of taxes. Biocytogen shall provide Ideaya any tax forms that may be reasonably necessary in order for Ideaya not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Notwithstanding the foregoing, if as a result of any action by Ideaya, including assignment, any change in Ideaya’s tax residency, or any failure on the part of Ideaya to comply with Applicable Laws (including filing or record retention requirements), incremental taxes are imposed that were not otherwise applicable, then Ideaya shall be solely responsible for the amount of such incremental taxes.

Exhibit 10.1

(c)

Each Party shall provide the other with reasonable assistance to enable the reduction, credits, or recovery, as permitted by Applicable Laws, of withholding taxes, or sales, use, value added or similar taxes (each an “Indirect Tax”), or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or Indirect Tax. For clarity, Biocytogen will bear any Indirect Taxes imposed by the applicable tax authorities in China on payments made under this Agreement. In the event any tax authority outside of China imposes any Indirect Tax on payments made under this Agreement and such imposition does not result from the actions of either Party (such as changing such Party’s location or jurisdiction), the Parties shall discuss in good faith a reasonable allocation of such Indirect Tax to be borne by each Party. Notwithstanding the foregoing, if as a result of any action by Biocytogen, including assignment, any change in Biocytogen’s tax residency, or any failure on the part of Biocytogen to comply with Applicable Laws (including filing or record retention requirements), incremental taxes are imposed that were not otherwise applicable, then Biocytogen shall be solely responsible for the amount of such incremental taxes.

8.4

Records; Audit. Ideaya shall keep, and shall have its Affiliates and Sublicensees keep, complete and accurate records pertaining to the sale or other disposition of Licensed Products in sufficient detail to permit Biocytogen to confirm the accuracy of commercial milestone and royalty payments due hereunder. Such records shall be kept for [***] following the end of the Calendar Quarter to which they pertain, or such longer period as may be required under Applicable Law. Biocytogen shall have the right to have an independent, certified public accountant reasonably acceptable to Ideaya audit records of Ideaya, its Affiliates or Sublicensees to confirm Net Sales, royalties, and Commercial Milestone Payments for a period covering not more than [***]. Such audits may be conducted during normal business hours upon reasonable prior written notice to Ideaya, and not more than [***]. Any such auditor shall not disclose Ideaya’s Confidential Information to Biocytogen, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by Ideaya or the amount of payments by Ideaya under this Agreement, and shall enter into a customary confidentiality agreement with Ideaya. Any amounts shown to be owed but unpaid shall be paid within [***] after the accountant’s report, plus interest (as set forth in Section 8.5) from the original due date. Any overpayment by Ideaya revealed by an audit shall be credited against future payments owed by Ideaya to Biocytogen (and if no further payments are due, shall be refunded by Biocytogen to Ideaya within [***] after the accountant’s report). Biocytogen shall bear the full cost of such audit unless such audit discloses an underpayment by Ideaya of more than the greater of [***].

8.5

Late Payments. In case of a delay of any undisputed payment under this Agreement, Ideaya will pay Biocytogen interest on any payments that are not paid on the date on which such payments are due under this Agreement at a monthly interest rate equal to [***].

Exhibit 10.1

Article IX.

Intellectual Property

9.1

Background IP. All right, title and interest in and to the Know-How and Patents Controlled by a Party prior to the Effective Date or independent of this Agreement shall be solely owned by such Party.

9.2

Ownership of Arising IP. To the extent allowed under each Applicable Law of the applicable jurisdiction, ownership of Inventions shall be determined in accordance with U.S. patent law. If U.S. patent law is not allowed and a different Party is considered owner and/or inventor of a given Invention under national patent law, such Party shall assign, or cause to assign, the Invention to the rightful owner as determined under U.S. patent law. Each Party shall solely own any Intellectual Property relating to the Licensed Compound or Licensed Product made solely by it or its Affiliates, or its or their respective employees, agents, or independent contractors (Inventions therein, “Sole Inventions”; Ideaya’s Know-How therein, “Ideaya Know-How”, and Biocytogen’s Know-How therein, “Biocytogen Know-How”) under this Agreement. The Parties shall jointly own any Intellectual Property that is made jointly by employees, agents, or independent contractors of one Party or its Affiliates together with employees, agents, or independent contractors of the other Party or its Affiliates (Inventions therein, “Joint Inventions”; Know-How therein, “Joint Know-How”). Sole Inventions, Ideaya Know-How, Biocytogen Know-How, Joint Inventions, Joint Know-How, and Patents claiming any of the Sole Inventions or Joint Inventions are collectively “Arising IP”. Notwithstanding the foregoing, Joint Inventions shall include any Inventions that are derived from, or are improvements of any Intellectual Property that relates solely to the Licensed Compound, whether made solely by a Party or its Affiliates, or jointly by the Parties or their Affiliates. All Patents claiming Joint Inventions shall be referred to herein as “Joint Patents.” [***] Except to the extent either Party is restricted by the licenses granted to the other Party under this Agreement, each Party shall be entitled to practice, license, assign, and otherwise exploit the Joint Inventions, Joint Know-How, and Joint Patents without the duty of accounting to the other Party or seeking consent from the other Party. References in this Section 9.2 to generation of Intellectual Property by a Party or its Affiliates shall include generation by either Party’s or its Affiliates’ respective employees, agents, or independent contractors. Notwithstanding anything to the contrary herein, prior to the Option Exercise Date or absent exercise of the Option, unless otherwise agreed between the Parties, (i) Ideaya Know-How, Biocytogen Know-How other than Platform IP, and Joint Know-How shall be deemed Confidential Information of both Parties, and neither Party shall disclose any Ideaya Know-How, Biocytogen Know-How other than Platform IP, or Joint Know-How to any Third Party unless and solely to the extent necessary for performance of the Agreement as permitted hereunder; (ii) neither Party shall use Ideaya Know-How, Biocytogen Know-How other than Platform IP, or Joint Know-How to prepare or file any patent application, apply for clinical trials or other document seeking to establish any similar proprietary protection; and (iii) neither Party shall use the Ideaya Know-How, Biocytogen Know-How other than Platform IP, or Joint Know-How for any purpose other than the Option Period Studies or evaluation of the Option.

9.3

Disclosure of Inventions and Know-How. Each Party shall promptly disclose to the other Party (a) its Sole Inventions and Know-How that arise in the performance of activities under this Agreement and (b) Joint Inventions and Know-How, including any invention

Exhibit 10.1

disclosures or other similar documents submitted to it by its employees, agents, or independent contractors describing such Inventions, and shall promptly respond to reasonable requests from the other Party for additional information relating to such Inventions and KnowHow.

9.4

Patent Prosecution and Maintenance.

(a)

Licensed Product Patents other than Joint Patents. After Ideaya’s Option Exercise:

(i)

Subject to this Section 9.4(a), as between the Parties, Ideaya shall have the first right, but not the obligation to control the preparation, filing, prosecution, and maintenance (including any interferences, reissue proceedings, reexaminations, patent term extensions, applications for supplementary protection certificates, oppositions, invalidation proceedings, and defense of validity or enforceability challenges) of all Licensed Patents (excluding, for clarity, any Joint Patents) directed to the Licensed Compound (not solely directed to the Designated Payload, Designated Linker, or the Designated Antibody) (“Licensed Product Patents”, the scope of which as of the Effective Date is set forth in Exhibit 1.73) in the Territory, at its sole cost and expense and by counsel of its own choice. Subject to the foregoing with respect to the Licensed Product Patents, during the Term hereof, Biocytogen shall have the sole right to file, prosecute and maintain all Licensed Patents (excluding for purpose of this Section 9.4(a)(i), for clarity, any Joint Patents) at Biocytogen’s sole cost and expense.

(ii)

Ideaya shall consult with Biocytogen and keep Biocytogen reasonably informed of the status of such Licensed Product Patents in the Territory and shall promptly provide Biocytogen with all material correspondence received from any patent authority in connection therewith. In addition, Ideaya shall promptly provide Biocytogen with drafts of all proposed material filings and correspondence to any patent authority with respect to such Licensed Product Patents in the Territory sufficiently in advance of any applicable filing deadlines for Biocytogen’s review and comment prior to the submission of such proposed filings and correspondences. [***]

(iii)

in the event that Ideaya desires to abandon or cease prosecution or maintenance of any Licensed Product Patent in the Territory that is applicable to the Field, Ideaya shall provide reasonable prior written notice to Biocytogen of such intention to abandon (which notice shall, to the extent possible, be given no later than [***] prior to the next deadline for any action that must be taken with respect to any such Licensed Product Patent in the relevant patent office). In such case, upon Biocytogen’s written election provided no later than [***] after such notice from Ideaya, Biocytogen shall have the right to assume the prosecution and maintenance of such Licensed Product Patent at Biocytogen’s expense. For clarity, if Biocytogen does not provide such election within [***] after such notice from Ideaya, Ideaya may, in its sole discretion, continue or discontinue prosecution and maintenance of such Licensed Product Patent.

(b)

Joint Patents. After Ideaya’s Option Exercise:

(i)

Subject to this Section 9.4(b), as between the Parties, Ideaya shall have the first right, but not the obligation, to control the preparation, filing, prosecution, and

(ii)

Ideaya shall consult with Biocytogen and keep Biocytogen reasonably informed of the status of the Joint Patents and shall promptly provide Biocytogen with all material correspondence received from any patent authority in connection therewith. In addition, Ideaya shall promptly provide Biocytogen with drafts of all proposed material filings and correspondence to any patent authority with respect to the Joint Patents sufficiently in advance of any applicable filing deadlines for Biocytogen’s review and comment prior to the submission of such proposed filings and correspondences. [***]

(iii)

in the event that Ideaya desires to abandon or cease prosecution or maintenance of any Joint Patent in any country, Ideaya shall provide reasonable prior written notice to Biocytogen of such intention to abandon or cease prosecution or maintenance of any Joint Patent (which notice shall, to the extent possible, be given no later than [***] prior to the next deadline for any action that must be taken with respect to any such Joint Patent in the relevant patent office). In such case, upon Biocytogen’s written election provided no later than [***] after such notice by Ideaya, Ideaya shall assign its rights and title in such Joint Patent to Biocytogen and Biocytogen shall acquire all rights and title in such Joint Patent at its expense. If Biocytogen does not provide such election within [***] after such notice, Ideaya may, in its sole discretion, continue or discontinue prosecution and maintenance of such Joint Patent.

(c)

Ideaya’s Solely Owned Patents. After Ideaya’s Option Exercise, as between the Parties, Ideaya shall have the sole right to file, prosecute and maintain all Patents that are solely owned by Ideaya (each, an “Ideaya Patent”), at Ideaya’s sole cost and expense. Ideaya shall keep Biocytogen reasonably informed of the status of such Patents.

(d)

Cooperation of the Parties. After Ideaya’s Option Exercise, each Party agrees to cooperate fully in the preparation, filing, prosecution, and maintenance of Patents under this Section 9.4 and in the obtaining and maintenance of any patent term extensions, supplementary protection certificates and their equivalent with respect thereto, at its own cost. Such cooperation includes: (i) executing all papers and instruments, or requiring its employees or contractors, to execute such papers and instruments, so as enable the other Party to apply for and to prosecute patent applications in any country as permitted by this Section 9.4; and (ii) promptly informing the other Party of any matters coming to such Party’s attention that may affect the preparation, filing, prosecution, or maintenance of any such patent applications.

9.5

Infringement by Third Parties.

(a)

Notice. Each Party shall notify the other Party within [***] of becoming aware of any alleged or threatened infringement by a Third Party of any of the Licensed Patents or Joint Patents in the Territory, including any declaratory judgment, opposition, or similar action alleging the invalidity, unenforceability, or noninfringement of any of the Licensed Patents or Joint Patents.

Exhibit 10.1

(b)

Enforcement Right.

(i)

After Ideaya’s Option Exercise, as between the Parties, Ideaya shall have (A) the sole right, but not the obligation, to bring and control any action or proceeding with respect to infringement or challenge of any Ideaya Patent, and (B) the first right, but not the obligation, to bring and control any action or proceeding with respect to infringement or challenge of any Licensed Patent or Joint Patent in the Field in the Territory relating to a Licensed Product by a Third Party product (“Product Infringement”), in each case at its own expense and by counsel of its own choice. Biocytogen shall have the right, at its own expense, to be represented in any action under subsection (A) or (B), in each case by counsel of its own choice, and Ideaya and its counsel will reasonably cooperate with Biocytogen and its counsel in strategizing, preparing, and litigating any such action or proceeding. If Ideaya fails to bring an action or proceeding with respect to Product Infringement of any Licensed Patent or Joint Patent in the Territory within (X) [***] following the notice of alleged infringement or declaratory judgment or (Y) [***] before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such actions, whichever comes first, Biocytogen shall have the right, but not the obligation, to bring and control any such action at its own expense and by counsel of its own choice, and Ideaya shall have the right, at its own expense, to be represented in any such action by counsel of its own choice, and Biocytogen and its counsel will reasonably cooperate with Ideaya and its counsel in strategizing, preparing, and litigating any such action or proceeding.

Ideaya shall have the sole right to retain any recovery or damages realized as a result of any action or proceeding in relation to any Ideaya Patent, and any such amounts shall not be treated as Net Sales for the purposes of this Agreement.

(c)

Cooperation. In the event that a Party brings an action in accordance with this Section 9.5, the other Party shall cooperate fully, including, if required to bring such action, the furnishing of a power of attorney or being named as a party to such action.

9.6

Infringement of Third Party Rights. If any Licensed Compound or Licensed Product used or sold by Ideaya, its Affiliates, or Sublicensees becomes the subject of a Third Party’s claim or assertion of infringement of any intellectual property rights in a jurisdiction within the Territory, Ideaya shall promptly notify Biocytogen, and the Parties shall promptly meet to consider the claim or assertion and the appropriate course of action and may, if appropriate, agree on and enter into a “common interest agreement” wherein the Parties agree to their shared, mutual interest in the outcome of such potential dispute. Absent any agreement to the contrary, and subject to claims for indemnification under Article 11, each Party will defend itself from any such Third Party claim at its own cost and expense, provided, however, that the provisions of Section 9.5 shall govern the right of the Parties to assert a counterclaim of infringement of any Licensed Patent or Joint Patent.

9.7

Consent for Settlement. Neither Party shall unilaterally enter into any settlement or compromise of any action or proceeding under this Article 9 that would in any manner alter,

Exhibit 10.1

diminish, or be in derogation of the other Party’s rights under this Agreement without the prior written consent of such other Party, which shall not be unreasonably withheld.

INDEMNIFICATION

11.1

Indemnification by Biocytogen. Biocytogen will defend, indemnify, and hold harmless Ideaya and its Affiliates and their respective directors, officers, employees and agents (each, an “Ideaya Representative”) from and against any and all liabilities, expenses, and losses, including reasonable legal expenses and attorneys’ fees (collectively, “Losses”), to which any Ideaya Representative may become subject as a result of any claim, demand, action, or other proceeding by any Third Party (a “Claim”) to the extent such Losses arise out of: (a) the Development, Manufacture, Commercialization, use, handling, or storage of any Licensed Compound or Licensed Product by Biocytogen or its Affiliates, (b) the negligence or willful misconduct of any Biocytogen Representative, or (c) the breach by Biocytogen of any warranty, representation, covenant, or agreement made by Biocytogen in this Agreement; except, in each of subsection (a), (b), and (c), to the extent such Losses are subject to Ideaya’s obligations pursuant to Section 11.2.

11.2

Indemnification by Ideaya. Ideaya will defend, indemnify, and hold harmless Biocytogen and its Affiliates and their respective directors, officers, employees, and agents (each, a “Biocytogen Representative”) from and against any and all Losses to which any Biocytogen Representative may become subject as a result of any Claim to the extent such Losses arise out of: (a) the Development, Manufacture, Commercialization, use, handling, or storage of any Licensed Compound or Licensed Product by Ideaya or its Affiliates or Sublicensees in the Territory, (b) the negligence or willful misconduct of any Ideaya Representative, or (c) the breach by Ideaya of any warranty, representation, covenant, or agreement made by Ideaya in this Agreement; except, in each of subsection (a), (b), and (c), to the extent such Losses are subject to Biocytogen’s obligations pursuant to Section 11.1.

11.3

Procedure. A party that intends to claim indemnification under this Article 11 (the “Indemnitee”) shall promptly notify the indemnifying Party (the “Indemnitor”) in writing of any Claim in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor shall have sole control of the defense or settlement thereof. The Indemnitee may participate at its expense in the Indemnitor’s defense of and settlement negotiations for any Claim with counsel of the Indemnitee’s own selection. The indemnity arrangement in this Article 11 shall not apply to amounts paid in settlement of any action with respect to a Claim, if such settlement is effected without the consent of the Indemnitor, which consent shall not be unreasonably withheld or delayed. The failure to deliver written notice to the Indemnitor within a

Exhibit 10.1

reasonable time after the commencement of any action with respect to a Claim shall only relieve the Indemnitor of its indemnification obligations under this Article 11 if and to the extent the Indemnitor is actually prejudiced thereby. The Indemnitee shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action with respect to a Claim covered by this indemnification.

11.4

Insurance. Ideaya, at its own expense, shall maintain product liability and other appropriate insurance (or self-insure) in an amount consistent with sound business practice and reasonable in light of its obligations under this Agreement during the Term.

Article XII.

CONFIDENTIALITY

12.1

Confidential Information. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties, the Parties agree that, during the Term and for [***] (or, for any trade secret, for so long as such trade secret constitutes a trade secret under Applicable Law), the receiving Party shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as expressly provided for in this Agreement any Confidential Information of the other Party under this Agreement, and both Parties shall keep confidential and, subject to Sections 12.2 and 12.3 and 12.5, shall not publish or otherwise disclose the terms of this Agreement. Each Party may use the other Party’s Confidential Information only to the extent required to accomplish the purposes of this Agreement, including exercising its rights or performing its obligations. Each Party will use at least the same standard of care as it uses to protect proprietary or Confidential Information of its own (but no less than reasonable care) to ensure that its employees, agents, consultants, contractors, and other representatives do not disclose or make any unauthorized use of the Confidential Information of the other Party. Each Party will promptly notify the other Party upon discovery of any unauthorized use or disclosure of the Confidential Information of the other Party. [***]

12.2

Exceptions. The obligations of confidentiality and restriction on use under Section 12.1 will not apply to any information that the receiving Party can prove by competent written evidence: (a) is now, or hereafter becomes, through no act or failure to act on the part of the receiving Party, generally known or available to the public; (b) is known by the receiving Party at the time of receiving such information, other than by previous disclosure of the disclosing Party, or its Affiliates, employees, agents, consultants, or contractors; (c) is hereafter furnished to the receiving Party without restriction by a Third Party who has no obligation of confidentiality or limitations on use with respect thereto, as a matter of right; or (d) is independently discovered or

Exhibit 10.1

developed by the receiving Party without the use of Confidential Information belonging to the disclosing Party.

12.3

Authorized Disclosure. Each Party may disclose Confidential Information belonging to the other Party as expressly permitted by this Agreement or if and to the extent such disclosure is reasonably necessary in the following instances:

(a)

filing, prosecuting, or maintaining Licensed Patents and Joint Patents as permitted by this Agreement;

(b)

(d)

Remaining Inventories. If this Agreement is terminated, Ideaya and its Affiliates and Sublicensees shall have the right to sell any or all of the inventory of Licensed Products held by Ideaya and its Affiliates and Sublicensees as of the date of termination for a period of [***] following such termination, so long as such sales are made in the normal course consistent with Ideaya’s past practice and Ideaya continues to comply with all of its payment, reporting and audit obligations hereunder with respect to the Licensed Products.

South San Francisco, CA and Beijing, China, July X, 2024– IDEAYA Biosciences, Inc. (Nasdaq: IDYA), a precision medicine oncology company committed to the discovery and development of targeted therapeutics, announced that it has entered into an option and license agreement for a potential first-in-class B7H3/PTK7 BsADC program with Biocytogen Pharmaceuticals (Beijing) Co., Ltd. (Biocytogen, HKEX: 02315), a global biotech company focusing on the discovery of novel antibody/ADC therapeutics.

“The potential first-in-class B7H3/PTK7 topo-I-payload BsADC program has the potential to be developed as a monotherapy agent in multiple solid tumor types, and advances IDEAYA’s broader corporate strategy to enable wholly-owned first-in-class rational combinations at the intersection of ADCs and small molecule DDR-based therapies to deliver greater benefit for patients,” said ▇▇▇▇▇▇ ▇. ▇▇▇▇, President and Chief Executive Officer, IDEAYA Biosciences.

“We are thrilled to announce our collaboration with IDEAYA to explore the promising combination of our potential first-in-class ADC and IDEAYA’s DDR small molecules,” said Dr. ▇▇▇▇▇▇ ▇▇▇▇, President and CEO of Biocytogen. “This partnership leverages our cutting-edge RenLite® platform and proprietary linker-payload technology to enhance the precision and potency of ADCs. IDEAYA's strong determination and rich experience in drug development make us confident that this therapy could be rapidly advanced to benefit patients.”

The agreement grants IDEAYA an option for an exclusive worldwide license from Biocytogen for a potential first-in-class B7H3/PTK7 topo-I-payload BsADC program. B7H3/PTK7 has been found to be co-expressed in multiple solid tumor types, including double-digit percent prevalence in lung, colorectal, and head and neck cancers, among others.

Under the terms of the agreement, Biocytogen will receive an upfront fee and upon an option exercise by IDEAYA, be entitled to receive an option exercise fee, development and regulatory milestones and commercial milestone payments, as well as single-digit royalties on net sales. Total potential upfront, option exercise and milestone payments equal an aggregate of $406.5 million, including development and regulatory milestones of $100.0 million.

Based on preclinical data, the potential first-in-class B7H3/PTK7 topoisomerase-I-inhibitor-payload BsADC program has the potential to be developed as a monotherapy agent and used in combination with multiple programs in IDEAYA’s pipeline targeting DDR-based therapies, including PARG inhibitor IDE161. A development candidate nomination for the B7H3/PTK7 topoisomerase-I-inhibitor payload BsADC program is targeted for the second half of 2024.
