Cost Share Adjustment.  With respect to each Licensed Product that is Commercialized hereunder, twice during the Term following the date on which First Commercial Sale of such Licensed Product occurs in each of [***] (the date of the occurrence of the last of such [***], the “Global Commercialization Date”), at both three (3) and six (6) years after such Global Commercialization Date with respect to such Licensed Product, the Parties shall engage a Big Four Accounting Firm, as mutually agreed by the Parties, to calculate the actual worldwide profits of such Licensed Product in accordance with GSK’s Accounting Standard.  If such Big Four Accounting Firm concludes that the profits of such Licensed Product in the U.S. is not equal to [***]% of such profits for such Licensed Product globally in each case, for the then-preceding year, then the Parties shall adjust the 20% IDEAYA/80% GSK Development Cost share ratio set forth in Section 6.2.4 (“Cost Share Ratio”) to reflect the actual relative profits in the U.S. compared to the profits in the world other than the U.S. as follows: for each [***] [***]% profits of such Licensed Product in the U.S. as compared to worldwide profits of such Licensed Product as determined by the Big Four Accounting Firm (“Relative U.S. Market Share”), the Cost Share Ratio of IDEAYA will be increased by [***] by [***]% of the Relative U.S. Market Share, the Cost Share Ratio of IDEAYA will be decreased by [***].  Such updated Cost Share Ratio will apply both prospectively to the sharing of future Development Costs hereunder, as well as retroactively to Development Costs previously reconciled for the three (3) years prior (such amount of Development Costs a Party owes to the other Party with respect to such Development Cost previously reconciled by way of such modified Cost Share Ratio, “True Up Costs”).  To the extent that IDEAYA owes to GSK any True Up Costs, GSK shall credit against any amounts otherwise due to IDEAYA under this Agreement until such True Up Costs are fully recouped by

GSK.  To the extent that GSK owes to IDEAYA any True Up Costs, GSK shall add such True Up Costs in its next payment due to IDEAYA pursuant to ARTICLE 7.

6.2.6

Technology Transfer.  Promptly following completion of the (a) WRN Program and (b) if applicable, the Option Closing Date, to the extent not previously transferred and delivered to GSK, IDEAYA shall transfer and deliver to GSK (in order to enable GSK to practice under the licenses granted to GSK under Section 8.2.1(a) and 8.1, respectively), IDEAYA Know-How and Know-How comprising Joint Arising Technology (including Materials) in its Control (including any Know-How arising from the Interim MAT2A Activities), in each case to the extent necessary to enable GSK to Develop, Manufacture and Commercialize WRN Compounds and WRN Products and, solely if the Option Closing Date occurs, the MAT2A Compounds and MAT2A Products as contemplated under this Agreement.  Without limiting the foregoing, IDEAYA shall use Commercially Reasonable Efforts to facilitate orderly transition and uninterrupted Development of the applicable Licensed Compounds and Licensed Products. The format of, and media for exchanging, any of the foregoing information shall be decided by the applicable JDC.

6.2.7

Reporting.  Commencing six (6) months following the initial submission of a Development Plan and Development Budget for the applicable Licensed Compounds and Licensed Products to the JDC in accordance with Section 6.2.2, and every six (6) months thereafter until (i) Regulatory Approval by the FDA of the first Marketing Approval Application for such Licensed Product or (ii) permanent cessation of Development of all applicable Licensed Compounds and Licensed Products, GSK shall provide to the applicable JDC and JSC a report setting out the status of GSK’s material activities with respect to the Development of such Licensed Compounds and Licensed Products conducted for the prior year, any material issues affecting Development or timelines for Development, as well as a high-level plan showing anticipated material inflection points in the coming year (the “Development Reports”).  GSK shall provide Development Reports to the applicable JDC and the JSC for so long as they are in existence and GSK is required to provide such Development Report as described above.  

6.2.8

Non-Exercise of Option.  Notwithstanding any other provision in this Section 6.2 or any other provision of this Agreement to the contrary, if GSK does not exercise the Option within the Exercise Period, then as of the expiration of the Exercise Period, this Agreement shall automatically terminate with respect to the MAT2A Target, and GSK shall have no rights whatsoever under this Agreement or under any Patents, Know-How, or other intellectual property Controlled by IDEAYA or its Affiliates (including IDEAYA Technology) to make, have made, use, sell, offer for sale and import, or otherwise exploit any MAT2A Compound or MAT2A Product, and IDEAYA shall have the right, but not the obligation, to make, have made, use, sell, offer for sale and import, or otherwise exploit all MAT2A Compounds and MAT2A Products which it owns or otherwise Controls, at its sole cost and sole discretion.

6.3

Diligence.  GSK shall use Commercially Reasonable Efforts in the exercise of its rights and performance of its obligations under Sections 6.1 and 6.2, including the activities set forth in each Development Plan and Commercialization Plan. Without limiting the forgoing, GSK shall use Commercially Reasonable Efforts to Develop and Commercialize (a) solely

following the Option Closing Date, [***], (b) [***], and (c) [***], in each case in the Field and [***]. GSK shall conduct its Development and Commercialization activities in good scientific manner (as applicable) and in compliance with its Internal Policies, Applicable Law, including those regarding the environment, safety and industrial hygiene, and GMP, GLP, GCP, informed consent and Institutional Review Board regulations, current standards for pharmacovigilance practice, and all applicable requirements relating to the protection of human subjects.  

6.4

Subcontracting. GSK may engage its Affiliates, Sublicensees or Third Party subcontractors (including distributors, contract research organizations and contract manufacturing organizations) to perform certain of its obligations under the Development Plans, Commercialization Plans or otherwise in connection with its obligation to Develop, Manufacture and Commercialize Licensed Compounds and Licensed Products under this Agreement. GSK shall cause any subcontract between GSK and any Third Party subcontractor used by GSK to perform such obligations to provide that all intellectual property rights conceived, created or generated during the performance of such services material to the Development, Manufacture or Commercialization of such Licensed Compounds or Licensed Products contemplated by this Agreement shall be owned or Controlled by GSK.  GSK’s use of Affiliates, Sublicensees or subcontractors shall not relieve GSK of any obligation hereunder and GSK shall cause its Affiliates, Sublicensees or subcontractors to comply with its applicable obligations under this Agreement.  GSK shall remain responsible under this Agreement for ensuring, and shall be liable to IDEAYA for, the compliance of Affiliates, Sublicensees and subcontractors with this Agreement.  Any Third Party subcontractor to be engaged by GSK to perform GSK’s obligations under this Agreement shall meet the qualifications typically required by GSK for the performance of work similar in scope and complexity to the subcontracted activity.  

7.1

Upfront Payment; Equity Investment.

7.2

Reimbursement of POLQ Program Costs.  Within [***] days after the end of each Calendar Quarter during the conduct of the POLQ Program, IDEAYA, in accordance with GAAP, shall submit to GSK a reasonably detailed report and any additional documentation reasonably requested by GSK, setting forth all Development Costs for the Development of the POLQ Compounds and POLQ Products in the Field in the Territory actually incurred by IDEAYA in the conduct of the POLQ Program in accordance with the applicable Collaboration Plan and Collaboration Budget during such Calendar Quarter (the “POLQ Program Costs”).  GSK shall reimburse IDEAYA for the POLQ Program Costs incurred as set forth in such report; provided that any POLQ Program Costs incurred in excess of [***] of the budgeted POLQ Program Costs for the applicable Calendar Quarter shall be borne by IDEAYA unless such overage was approved in advance by the applicable JDC and JSC.  Notwithstanding the foregoing, any POLQ Program Costs that are incurred by IDEAYA as a result of IDEAYA’s failure to use Commercially Reasonable Efforts in performing its obligations under the POLQ Program or due to IDEAYA’s negligence, whether or not such POLQ Program Costs are in excess of [***] of the Development Budget for the applicable Calendar Quarter, shall be borne entirely by IDEAYA.  GSK shall reimburse POLQ Program Costs within [***] days after receipt of an invoice from IDEAYA.

7.3

Sharing of WRN Program Costs, WRN Development Costs, and MAT2A Development Costs.  

7.3.1

Reports; Reconciliation Payments.  Subject to Section 7.3, with respect to (a) WRN Program Costs incurred by the Parties in accordance with Section 4.2 and (b)

WRN Development Costs and MAT2A Development Costs incurred by the Parties in accordance with Section 6.2.4 ((a) and (b) referred to collectively as the “Shared Development Costs”), within [***] days following the end of each Calendar Quarter during which any such Shared Development Costs are incurred, each of IDEAYA and GSK (as applicable), in accordance with Accounting Standards, shall submit to the Financial Working Group a written report setting forth in reasonable detail all WRN Program Costs, WRN Development Costs or MAT2A Development Costs incurred by each such Party over such Calendar Quarter, provided, however, that a preliminary estimate of the Shared Development Costs, in a format agreed by the Financial Working Group, shall be provided by each IDEAYA and GSK within [***] days following the end of the Calendar Quarter for purposes of financial statement close process. For clarity, such estimate may be based on forecasted numbers and the Parties agree that the final Development Costs and other Allowable Expenses reported in the Financial Reports may differ from this estimate.  Within [***] days following the receipt by the Financial Working Group of such written reports, the Financial Working Group shall prepare and submit to each Party a written report (the “Financial Reports”) setting forth in reasonable detail (i) the calculation of all such Shared Development Costs incurred by both Parties over such Calendar Quarter and any deviations from the applicable Collaboration Budget or Development Budget, and (ii) the calculation of the net amount owed by GSK to IDEAYA or by IDEAYA to GSK in order to ensure the appropriate sharing of such Shared Development Costs in accordance with Sections 4.2 and 6.2.4.  The Party that is due for reimbursement of Shared Development Costs shall invoice the other Party within [***] days of receipt of such report from the Financial Working Group.  Such payments by one Party to reimburse the other Party’s expenditures for Shared Development Costs shall be paid within [***] days following receipt of the invoice.  Any WRN Program Costs, WRN Development Costs or MAT2A Development Costs incurred in excess of the agreed upon Collaboration Budget or Development Budget in any Calendar Quarter will be subject to the terms set forth in Section 7.3.2.

7.3.2

Overruns.    Each Party shall notify the other Party promptly upon becoming aware that the anticipated Development Costs to be incurred by such Party under a particular Collaboration Plan or Development Plan for a given Calendar Year shall be in excess of the applicable approved Collaboration Budget or Development Budget. Thereafter, the following shall apply:

(a)

Following such notification, the Financial Working Group, in consultation with the applicable JDC (as and if needed), shall discuss the causes of any such increase and evaluate potential mitigation measures to prevent a further increase of Development Costs. To the extent, based on this discussion, that the Financial Working Group concludes that the anticipated amount of the concerned category of Development Costs is likely not to exceed [***] of the amounts budgeted (the “Permitted Overage”) as set forth in the then-current applicable Development Budget, such anticipated Development Costs shall be included in the calculation of the applicable Development Costs for the purposes of determining the amounts to be paid from one Party to the other Party to reflect the sharing percentages set forth in Sections 4.2 and 6.2.4.

(c)

Notwithstanding the foregoing, any WRN Program Costs, WRN Development Costs or MAT2A Development Costs that are incurred by a Party as a result of that Party’s failure to use Commercially Reasonable Efforts in connection with performing its obligations hereunder or due to that Party’s negligence, whether or not such WRN Program Costs, WRN Development Costs or MAT2A Development Costs are in excess of [***] of the applicable Collaboration Budget or Development Budget for the applicable Calendar Year, shall be borne entirely by that Party.

7.4

Pre-Tax Profit or Loss Sharing.

7.4.1

Pre-Tax Profit or Loss.  Subject to Section 7.5, the Parties shall share in Pre-Tax Profit or Loss in the Profit-Sharing Territory solely with respect to  MAT2A Products (subject to occurrence of the Option Closing Date) and WRN Products as follows: IDEAYA shall bear (and be entitled to) fifty percent (50%), and GSK shall bear (and be entitled to) fifty percent (50%), commencing with the First Commercial Sale of the applicable Licensed Product in the Profit-Sharing Territory and continuing for as long as the relevant Licensed Product continues to be sold by GSK, its Affiliates, and their Sublicensees in the Profit-Sharing Territory (the “Profit-Sharing Term”). Procedures for reporting, quarterly reconciliation and other finance and accounting matters will be as set forth in the Pre-Tax Profit or Loss Schedule.

7.4.2

Income Taxes. Subject to Section 7.14, income and withholding Taxes imposed on either of the Parties hereunder shall not be included in Pre-Tax Profit or Loss hereunder.

7.5

Development Cost Share Opt Out.

7.5.1

Exercise by IDEAYA.  IDEAYA may, upon written notice to GSK, with respect to the [***] and with respect to [***] with respect to the relevant Licensed Compound or Licensed Product, opt out of future sharing of Shared Costs and the Pre-Tax Profit or Loss in the Profit Sharing Territory (the “IDEAYA Opt-Out”), in each case, with respect to either, as independently elected by IDEAYA, (i) the WRN Compounds and WRN Products or (ii) solely if the Option Closing Date occurs, the MAT2A Compounds and MAT2A Products (any such

Licensed Compounds and Licensed Products for which IDEAYA has exercised the IDEAYA Opt-Out as specified in the IDEAYA Opt-Out, the “Cost Share Opt Out Compounds and Products”).  Such notice shall specify the date upon which such IDEAYA Opt-Out will be effective (such date to be no sooner than [***] days after the date such notice is delivered to GSK pursuant to Section 16.5) (the “Cost Share End Date”).  Effective from and after the Cost Share End Date, sharing of Shared Development Costs and of the Pre-Tax Profit or Loss in the Profit Sharing Territory in accordance with the relevant provisions of this Agreement will no longer apply with respect to the Cost Share Opt Out Compounds and Products (and for clarity GSK shall be solely responsible for such costs that were previously shared hereunder, and shall have no obligation to share any Pre-Tax Profit or Loss in the form of profits in the Profit Sharing Territory with IDEAYA with respect to such Cost Share Opt Out Compounds and Products), but for clarity such Cost Share Opt Out Compounds and Product shall continue to be a “Licensed Compound” and “Licensed Product” (as applicable) under this Agreement, subject to this Section 7.5.  Notwithstanding the foregoing, IDEAYA shall continue to be responsible for its portion of Shared Development Costs obligations for any and all studies, solely to the extent as contemplated in the relevant Collaboration Plans and Development Plans in the form as they exist as of the date such IDEAYA Opt-Out notice is delivered to GSK, that are ongoing as of the Cost Share End Date until such studies have been completed.

7.5.2

Adjustment of Economics.  Effective from and after the Cost Share End Date, notwithstanding any other provision of this Agreement to the contrary, the following economic terms shall apply with respect to the applicable Cost Share Opt Out Compounds and Products:

7.6

Option Exercise Fee.  Subject to Section 7.6.1, GSK shall pay to IDEAYA a one-time, non-refundable, non-creditable fee of Fifty Million Dollars ($50,000,000.00) (the “Option Fee”) by the fifth (5th) day of the month following the sixtieth (60th) day from GSK’s receipt of an invoice from IDEAYA therefor, which invoice will be provided only after Option Exercise by GSK.  

7.6.1

HSR Filing. If GSK reasonably determines that the transactions to occur upon consummation of Option Exercise require an HSR Filing, then upon notice of Option Exercise (a) GSK shall provide notice of such HSR Filing obligation to IDEAYA (to the extent it has not already done so), (b) Section 2.2 shall apply with respect to the effectiveness of such Option Exercise (replacing Execution Date in the first sentence thereof with the notice date of Option Exercise) and (c) all rights and obligations of the Parties related to such Option or Option Exercise (including payment of the Option Fee and the grant of any license to GSK, but not with respect to making any HSR Filing) shall be tolled until the HSR Clearance Date.  The last sentence of Section 2.2 (i.e., a Party’s termination right) shall not apply to any delay in achieving the HSR Clearance Date with respect to an HSR Filing following notice of Option Exercise under this Section 7.5.1.  If the HSR Clearance Date with respect to such Option Exercise has not occurred on or before the date that is one hundred eighty (180) days after the date as of which both Parties have made their respective HSR Filings and the initial waiting period under the HSR Act has commenced with respect to such Option, then either Party may terminate the MAT2A Program upon notice to the other Party (and such termination, regardless of whether by IDEAYA or GSK, shall be treated as an automatic termination of this Agreement with respect to the MAT2A Target in accordance with Section 6.2.8).

7.7

Early Stage Development Milestones.  GSK shall make the non-refundable, non-creditable milestone payments to IDEAYA that are set forth below upon the first achievement by IDEAYA, GSK, or their respective Affiliates or Sublicensees, of the milestone events set forth below with respect to the applicable Licensed Compound or Licensed Product.  Each milestone shall be payable only once per Licensed Compound or Licensed Product of the same class as set forth in the table below; provided, that with respect to a given Target for which two or more Licensed Compounds in different classes achieve such milestones (for example, a POLQ ATPase Compound, a POLQ Polymerase Compound, or a POLQ Degrader Compound), GSK shall not be required to pay the GLP Toxicology Study Initiation milestone and the IND Acceptance by FDA milestone for the second (or any subsequent) Licensed Compound(s) to achieve those milestones unless, and until, such second (or applicable subsequent) Licensed Compound(s) achieves the Clinical Dose Expansion milestone.

Royalties and Payments.

7.12.1

Net Sales Royalties. In partial consideration for the rights and licenses granted to GSK under this Agreement, GSK will pay IDEAYA royalties on aggregate Net Sales of Licensed Products, on a Licensed Product–by–Licensed Product basis, in the applicable

Net Sales Territory in each Calendar Year at the royalty rates set out below. The period in which royalties are payable for any Licensed Product commences with the First Commercial Sale of the Licensed Product in a country within its Net Sales Territory and ends, with respect to that Licensed Product in that country upon the later to occur of either: (i) ten (10) years from First Commercial Sale of the Licensed Product in that country; or (ii) expiration of the last-to-expire Valid Patent Claim covering the composition of matter or method of use of the Licensed Product in that country (the “Royalty Term”).

7.12.2

No Valid Patent Claim. The foregoing provisions of Section 7.12.1 notwithstanding, the royalties payable with respect to Net Sales of Licensed Products shall be reduced, on a Licensed Product–by–Licensed Product and country-by-country basis, to [***] of the amounts otherwise payable pursuant to 7.12.1 and subject to Section 7.12.5 during any portion of the Royalty Term after expiration of the last-to-expire Valid Patent Claim covering the composition of matter or method of use of the applicable Licensed Product in that country.  

7.12.3

Generic Step-Down. If, on a Licensed Product–by–Licensed Product and country-by-country basis, one or more Generic Products of such Licensed Product are sold in such country, and Net Sales of such Licensed Product in such country in two (2) consecutive Calendar Quarters are less than [***] of the aggregate market of the Generic Products and Licensed Product, as measured by IQVIA (or other industry accepted source used by GSK at such time), then the royalties payable with respect to Net Sales of such Licensed Product pursuant to Sections 7.12.1 and 7.12.2 for such Calendar Quarter shall be reduced to [***] of the royalties otherwise payable pursuant to Section 7.12.1, subject to Section 7.12.5.

7.12.4

Third Party Payments.  GSK shall be entitled to credit against the royalties due to IDEAYA upon Net Sales of a Licensed Product in a country solely in the Net Sales Territory an amount equal to [***] of the total royalties paid by GSK to Third Parties with respect to license rights to Patents or Know-How Controlled by Third Parties that GSK reasonably determines, after consultation with counsel, are necessary to avoid infringement of such Third Party Patents or misappropriation of such Third Party Know-How in the manufacture, use, offer for sale, sale or importation of such Licensed Product solely in the Net Sales Territory; provided that all such credits pursuant to this Section 7.12.4 shall not reduce the royalties payable to IDEAYA with respect to a MAT2A Product in any country to less than [***] of the royalties otherwise due to IDEAYA pursuant to Section 7.12.1 and subject to Section 7.12.5; and provided further that, GSK shall have the right to carry forward for application against royalties payable to IDEAYA with respect to Net Sales of such Licensed Product solely in the Net Sales Territory in future periods any amount that is not so credited due to the limitation in the immediately preceding proviso (but for clarity subject to the floor stated in the preceding proviso).  

7.12.5

Royalty Floor.  In no event shall the cumulative royalty reductions and offsets in Sections 7.12.2–7.12.4 operate to reduce the total royalties due and payable by GSK to IDEAYA to more than [***] of the amounts as set forth in Section 7.12.1.

7.12.6

Royalty Reporting.  Each Calendar Quarter following the First Commercial Sale of a Licensed Product in the applicable Net Sales Territory, GSK shall furnish to IDEAYA a written report showing on a Licensed Product–by–Licensed Product and country-by-country basis (a) the Net Sales; and (b) the calculation of the royalties payable under this Agreement on account of those Net Sales.  Each royalty report along with the royalties shown to have accrued on that report are due and payable to IDEAYA within [***] days following the end of such Calendar Quarter.  All payments due under this Section 7.12 shall be made by bank wire transfer in immediately available funds to an account designated by IDEAYA.  

7.13

Audits.  Each Party shall, and shall ensure that its Affiliates and Sublicensees, keep complete and accurate records of the items underlying Shared Development Costs, and GSK shall, and shall ensure that its Affiliates and Sublicensees, keep complete and accurate records of Net Sales (for any royalty-bearing Licensed Products hereunder and for calculation of Pre-Tax Profit or Loss as applicable), and, in the case in which the Parties are sharing Pre-Tax Profit or Loss, Allowable Expenses and Other Income. Each Party will have the right, at its own expense and no more frequently than once in any twelve (12)-month period (except in the case of fraud), to have an independent, certified public accountant, selected by such Party from nationally reputable accounting firms in the United States or the United Kingdom and reasonably acceptable to the other Party, review any such records of the other Party in the location(s) where such records are maintained by the other Party upon [***] days’ prior written notice and during regular business hours and under obligations of confidentiality, for the sole purpose of verifying the basis and accuracy of payments made under this Agreement, with respect to any Calendar Year ending not more than three (3) years prior to the request of the auditing Party. If the review of such records reveals that the other Party has failed to accurately report financial information required to be reported hereunder, or to make any payment (or portion thereof) required under this Agreement, then the other Party shall pay to the auditing Party any underpaid amounts due

hereunder together with interest calculated in the manner provided in Section 7.16 within [***] days. If any such discrepancies are greater than [***] percent ([***]%) of the amounts actually due for the audited period, the other Party shall pay all reasonable costs incurred in conducting such review. Once a Party has conducted a review and audit of the other Party pursuant to this Section 7.13 in respect of any given period, it may not subsequently re-inspect the other Party’s records in respect of such period, unless a subsequent audit of a separate reporting period uncovers fraud on the part of the audited Party that is reasonably expected to have been occurring during the prior audited period. For clarity, however, if a discrepancy is identified by the accountant during the course of an audit and the Parties do not agree upon a resolution of such discrepancy, then the auditing Party’s accountant may re-inspect the books and records to the extent reasonably relevant to resolving such discrepancy.  Unless otherwise defined or stated, financial terms shall be calculated by the accrual method under the applicable Party’s Accounting Standards. Financial records related to the foregoing shall be maintained (in such form as may be available) by each Party for a period of no less than seven (7) years following the end of the period to which they pertain.

7.14

Tax Matters.  Each Party will make all payments to each other under this Agreement without deduction or withholding for Taxes except to the extent that any such deduction or withholding is required by Applicable Law in effect at the time of payment.  The Parties shall reasonably cooperate with one another to reduce or minimize any such deduction or withholding required by Applicable Law, including by providing reasonable advance notice of such deduction or withholding by providing any forms or other certifications necessary to reduce the amount of such withholding.

7.14.1

Any amount payable by one Party to the other under this Agreement is deemed to be exclusive of any amount in respect of any VAT chargeable on the supply for which that sum is the consideration (in whole or in part) for VAT purposes. If anything done by one Party under this Agreement constitutes, for VAT purposes, the making of a supply to the other Party and VAT is or becomes chargeable on that supply, the Party receiving the supply shall pay the other Party, in addition to any amount otherwise payable under this Agreement by the Party receiving the supply, a sum equal to the amount of the VAT chargeable on that supply against delivery of a valid VAT invoice to the Party receiving the supply.  

7.14.2

Any Tax required to be withheld on amounts payable under this Agreement will promptly be paid by the Party making the payment (the “Payor”) on behalf of the Party receiving the payment (the “Payee”) to the appropriate governmental authority, and Payor will furnish Payee with proof of payment of such Tax. Any such Tax required to be withheld will be an expense of and borne by Payee, except that notwithstanding anything to the contrary in this Agreement, if a Payor assigns, transfers or otherwise disposes of some or all of its rights and obligations to any Person (without the prior written consent of the Payee) and if, as a result of such action, the withholding or deduction of tax required by Applicable Law with respect to payments under this Agreement is increased (the “Increased Withholding Taxes”), then any amount payable to the Payee under this Agreement shall be increased to take into account such Increased Withholding Taxes as may be necessary so that, after making all required withholdings (including

withholdings on the withheld amounts), the Payee receives an amount equal to the sum it would have received had no such Increased Withholding Taxes been made.

7.14.3

The Parties will cooperate with respect to all documentation required by any taxing authority or reasonably requested by either Party to secure a reduction in the rate of applicable withholding Taxes or an exemption from withholding Taxes. Notwithstanding the foregoing, if a Party is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, or recovery of, applicable withholding tax, then it may deliver to the other Party or the appropriate governmental authority the prescribed forms necessary to reduce the applicable rate of withholding or to relieve the Payor of its obligation to withhold tax. If a Payee timely delivers to the Payor a validly executed form establishing a reduced rate or exemption from withholding, the Payor shall apply the reduced rate of withholding, or not withhold, as the case may be, provided that the Payor is in receipt of evidence, in a form reasonably satisfactory to the Payor. If, in accordance with the foregoing, the Payor withholds any amount, then it will pay to the Payee the balance when due, timely remit to the proper taxing authority of the withheld amount, and send the Payee proof of such remittance within [***] days following that remittance.

7.14.4

No Partnership. Nothing contained in this Agreement shall be deemed or construed by the Parties, any of their Affiliates or any third person to treat the relationship between the Parties contemplated by this Agreement as a partnership, joint venture or other business entity under Treasury Regulations Section 301.7701-1(a)(2) (or any corresponding provision under state, local or non-U.S. tax Law) (an “Entity”).  Without the prior written consent of the Parties (such consent not to be unreasonably withheld, delayed or conditioned), no Party (or successor or assignee) shall, for Tax purposes, report the relationships established by this Agreement as an Entity, including either (a) making any disclosure that the relationships established by this Agreement may give rise to an Entity (whether on a U.S. Internal Revenue Service Form 8275 or otherwise) or (b) withholding any amounts from payments made to the other Party pursuant to Section 1446 of the Code (or any corresponding provision under state, local or non-U.S. tax law), unless required by a tax authority on audit or other examination.

7.15

Invoicing. To the extent an invoice is required to be submitted to GSK hereunder, such invoice shall include the information set forth in Schedule 7.15.    

7.16

Late Payments.  Without limiting either Party’s remedies under this Agreement, any undisputed payments or portions thereof due hereunder that are not paid on the date such payments are due under this Agreement shall bear interest at a rate equal to [***] percentage points above the prime rate as published by Citibank, N.A., New York, New York, or any successor thereto, at 12:01 a.m. on the first day of each Calendar Quarter in which such payments are overdue, calculated on the number of days such payment is delinquent.  Where the late payment is caused by the Party that is owed the payment, including for reasons such as failure to communicate in a timely manner changes to bank details, or failure to respond to communications from the Party owing the payment regarding the interpretation or dispute of the terms of such payment, then no interest will be payable by the Party owing the payment.

8.1

MAT2A Option; License.  Commencing on the Effective Date, IDEAYA hereby grants to GSK the exclusive option to obtain an exclusive, sublicensable (through multiple tiers and in accordance with this Agreement) license under the IDEAYA Technology to make, have made, use, sell, offer for sale and import MAT2A Compounds and MAT2A Products in the Field in the Territory (the “Option”).  GSK may exercise the Option at any time commencing on the Effective Date and (i) if the MAT2A Combination Study has not been Initiated prior to the Option Package Delivery Date, expiring on the date which is [***] after the Option Package Delivery Date, or (ii) if the MAT2A Combination Study has been Initiated prior to the Option Package Delivery Date, expiring [***] after the Option Package Delivery Date  (the time period until such expiration of GSK’s right to exercise the Option, the “Exercise Period”).  To exercise such Option (the “Option Exercise”), GSK shall provide written notice indicating such exercise to IDEAYA prior to expiration of the Exercise Period. The first day on which all of the following have occurred shall be deemed the “Option Closing Date”:  (1) IDEAYA has received such notice of Option Exercise, (2) the HSR Clearance Date has occurred or is deemed inapplicable in accordance with Section 7.6, and (3) IDEAYA has received the Option Fee in accordance with

Section 7.6.  Prior to GSK’s Option Exercise, during the Exercise Period IDEAYA shall (a) disclose to GSK, or make available to GSK by granting to GSK designated personnel access to a virtual data room containing, further Data (in addition to that required under the Option Data Package) including  preclinical, clinical, toxicology, CMC, regulatory documentation necessary for GSK to conduct diligence  (the “MAT2A Program Diligence Data”) within [***] days after the Option Package Delivery Date, and (b) as reasonably requested by GSK, provide GSK with reasonable consultation and assistance to the extent necessary or reasonably useful for GSK to understand and conduct diligence on the Option Data Package and MAT2A Program Diligence Data in a manner and on such timelines to enable GSK to make an informed decision in respect of the Option. Effective solely upon the Option Closing Date (if applicable), IDEAYA shall grant and hereby grants to GSK and its Affiliates an exclusive, royalty-bearing, sublicensable (through multiple tiers) license under the IDEAYA Technology to make, have made, use, sell, offer for sale and import MAT2A Compounds and MAT2A Products in the Field in the Territory during the Term. For clarity, GSK acknowledges and agrees that Section 6.2.8 shall apply if GSK does not timely exercise the Option during the Exercise Period and the Option Closing Date does not occur.

8.2

License Grants to GSK.  

8.2.1

IDEAYA hereby grants to GSK and its Affiliates, as of the Effective Date, an exclusive, royalty-bearing, sublicensable (through multiple tiers) license under the IDEAYA Technology to make, have made, use, sell, offer for sale and import (a) WRN Compounds and WRN Products, and (b) POLQ Compounds and POLQ Products, in each case of (a) and (b) in the Field in the Territory during the Term; provided that IDEAYA reserves the right under all such IDEAYA Technology to conduct activities assigned to it under the relevant Collaboration Plan for the WRN Program and POLQ Program; and provided further that such reservation of rights shall terminate upon completion of the WRN Program and POLQ Program, respectively.

The foregoing license shall expire on the earlier to occur of (a) the Option Closing Date; (b) expiration of the Option Period without exercise of the Option; or (c) completion by GSK of the GSK MAT2A Preclinical Activities under the relevant Collaboration Plan for the MAT2A Program.  The foregoing license shall be sublicensable to GSK’s Affiliates and subcontractors solely to the extent such Affiliates and subcontractors are performing any of the GSK MAT2A Preclinical Activities on behalf of GSK under the relevant Collaboration Plan for the MAT2A Program.  For the avoidance of doubt, the foregoing license does not include the right to conduct the MAT2A Combination Study and any license to IDEAYA Technology required for the conduct of the MAT2A Combination Study shall be as set forth in the MAT2A CTCSA.

8.3

License Grant to IDEAYA.  GSK hereby grants to IDEAYA as of the Effective Date, a non-exclusive, royalty-free, worldwide license under the GSK Technology solely for the purpose of (i) IDEAYA’s performance of its assigned activities under the relevant Collaboration Plan for the applicable Collaboration Program.  The forgoing licenses are sublicensable to IDEAYA’s Affiliates, Sublicensees, and subcontractors.  

8.4

Sublicenses. Each Party shall have the right to grant sublicenses to its Affiliates and shall have the further right to grant sublicenses to Third Parties (each, a “Sublicensee”), and any such sublicenses shall be subject to the conditions set forth in this ARTICLE 8.  Any and all sublicenses shall be in writing and shall be subject to, and consistent with, the terms and conditions of this Agreement applicable to Sublicensees. Each Party shall be responsible for ensuring the compliance of its Sublicensees with all obligations owed to the other Party under this Agreement, shall remain liable to the other Party for all acts and omissions of such Sublicensees and shall remain responsible for performance of all of its obligations to the other Party hereunder.  Neither Party’s grant of any sublicense will not relieve such Party or its Affiliates from any of its obligations under this Agreement.  To the extent GSK grants an exclusive sublicense to any Sublicensee of any rights exclusively licensed from IDEAYA hereunder (an “Exclusive Sublicense”), GSK shall promptly notify IDEAYA thereof and shall promptly thereafter provide IDEAYA with a copy of such Exclusive Sublicense, which copy may be reasonably redact the detailed financial terms of such Exclusive Sublicense agreement and which is deemed Confidential Information of GSK. As a condition precedent to and requirement of any such Exclusive Sublicense, if sales by such Sublicensee are included in Net Sales hereunder, such Sublicensee shall permit audit rights with respect to its reporting of Net Sales that are consistent with those given by GSK hereunder with respect to its sales included in Net Sales.

8.5

No Implied Licenses; Retained Rights.  Each Party acknowledges that the licenses granted under this ARTICLE 8 are limited to the scope expressly granted, and all other rights to Patents and Know-How licensed hereunder are expressly reserved to the Party granting the license to such Patents or Know-How.

8.6

Rights in Bankruptcy.  The Parties intend to take advantage of the protections of Section 365(n) (or any successor provision) of the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction to the maximum extent permitted by Applicable Law.  All rights and licenses granted under or pursuant to this Agreement, but only to the extent they constitute licenses of a right to “intellectual property” as defined in Section 101 of the U.S. Bankruptcy Code, shall be deemed to be “intellectual property” for the purposes of Section 365(n) or any analogous provisions in any other country or jurisdiction.  The non-bankrupt Party shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, including the right to obtain such intellectual property from another entity.  In the event of the commencement of a bankruptcy proceeding by or against a Party under the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, the non-bankrupt Party shall be entitled to a complete duplicate

of (or complete access to, as appropriate) all such intellectual property (including all embodiments of such intellectual property), which, if not already in the non-bankrupt Party’s possession, shall be promptly delivered to it upon its’s written request (a) upon commencement of a bankruptcy proceeding, unless the bankrupt Party continues to perform all of its obligations under this Agreement, or (b) if not delivered pursuant to clause (a) because the bankrupt continues to perform, upon the rejection of this Agreement by or on behalf of the bankrupt Party.  Unless and until the bankrupt Party rejects this Agreement, the bankrupt Party shall perform this Agreement or provide such intellectual property (including all embodiments of such intellectual property) to the non-bankrupt Party, and shall not interfere with the rights of the non-bankrupt Party to such intellectual property, including the right to obtain the intellectual property from another entity.  In the case of an insolvency that is governed by non-U.S. bankruptcy law, the Parties agree that, to the extent not prohibited by the applicable insolvency law, the non-bankrupt Party will be entitled to at least the same rights and protections afforded by the U.S. Bankruptcy Code, including survival of the licenses granted hereunder even if the bankrupt Party revokes or terminates this Agreement and a copy of the embodiments of such intellectual property, without conditions other than any legally required payment of royalties.  

9.1

Confidentiality.  Except to the extent expressly authorized by this Agreement or otherwise agreed by the Parties in writing, during the Term and for a period of ten (10) years following termination or expiration thereof (provided that with respect to any such Confidential Information which constitutes a bona fide trade secret of such Party as specifically identified by such Party as a trade secret to the other Party, in writing during the Term, such obligations shall continue for as long as such Confidential Information remains a trade secret), each Party will be obligated to keep confidential and not publish or otherwise disclose to a Third Party, and not to use, directly or indirectly, for any purpose, any Confidential Information furnished or otherwise made known to it, directly or indirectly, by the other Party, except to the extent such disclosure or use is expressly permitted by the terms of this Agreement or is reasonably necessary or useful for the performance of a Party’s obligations, or the exercise of such Party’s rights under, this Agreement.  The confidentiality and non-use obligations with respect to a Party’s Confidential Information in this Section 9.1 will not include any information that:

9.1.1

is or becomes part of the public domain through no wrongful act, fault or negligence on the part of the Receiving Party;

9.1.2

can be demonstrated by competent proof to have been in the Receiving Party’s possession prior to initial disclosure by the Disclosing Party without any obligation of confidentiality with respect to such information;

9.1.3

is subsequently received by the Receiving Party from a Third Party who is not bound by any obligation of confidentiality with respect to such information;

9.1.4

has been published by a Third Party or otherwise enters the public domain through no fault of the Receiving Party in breach of its contractual obligations to the Disclosing Party; or

9.1.5

can be demonstrated by competent proof to have been independently developed (outside the scope of this Agreement) by or for the Receiving Party without reference to or use of the Disclosing Party’s Confidential Information.

9.2

Authorized Disclosure.  The Receiving Party may disclose Confidential Information of the Disclosing Party to the extent that such disclosure is:

(a)

made in response to a valid order of a court or other governmental authority or, if in the reasonable opinion of the Receiving Party’s legal counsel, such disclosure is otherwise required by Applicable Law, including by reason of filing with securities regulators; provided that the Receiving Party shall, where practicable, first have given notice to the Disclosing Party and given the Disclosing Party a reasonable opportunity to quash such order or to obtain a protective order or confidential treatment; and provided further that the Confidential Information disclosed in response to such court or governmental order shall be limited to that information which is legally required to be disclosed in response to such court or governmental order;

(b)

made by or on behalf of the Receiving Party to Regulatory Authorities as required in connection with any filing, application or request for Regulatory Approval for the Licensed Products as permitted by this Agreement; provided that reasonable measures shall be taken to assure confidential treatment of such information to the extent practicable and consistent with Applicable Law;

(c)

made by or on behalf of the Receiving Party to a patent authority as may be reasonably necessary or useful for purposes of obtaining a Patent as permitted by this Agreement; provided that reasonable measures shall be taken to assure confidential treatment of such information, to the extent such protection is available; or

(d)

made by the Receiving Party to its attorneys, auditors, advisors, consultants, contractors, existing or prospective collaboration partners, licensees, sublicensees, existing or prospective investors, prospective acquirers, prospective lenders or other Third Parties as may be necessary in connection with the performance of this Agreement, in each case, for limited purposes; provided that such persons shall be subject to obligations of confidentiality and non-use with respect to such Confidential Information substantially similar to the obligations of confidentiality and non-use of the Receiving Party set forth herein.

9.3

Injunctive Relief.  Each Party, as a Receiving Party, acknowledges and agrees that due to the unique nature of a Disclosing Party’s Confidential Information, there may be no adequate remedy at law for any breach of its obligations hereunder and that any such breach may allow a Receiving Party or Third Parties unfairly to compete with the Disclosing Party, resulting in irreparable harm to the Disclosing Party. Therefore, notwithstanding the provisions

of Section 15.1, the Parties agree that upon any such breach or any threat thereof, the Disclosing Party shall be entitled to seek appropriate equitable relief at the Disclosing Party’s option in either (a) a court of competent jurisdiction where such Disclosing Party resides, or (b) as provided in Section 15.1, as applicable, in addition to whatever remedies it might have at law in connection with any breach or enforcement of a Receiving Party’s obligations hereunder for the unauthorized use or release of any such Confidential Information.

9.4

Data Breach. When transferring Confidential Information, all communications between GSK and IDEAYA will use encryption methods agreed to by the Parties.  Upon discovering any suspected or actual unauthorized disclosure, loss or theft of Confidential Information (a “Data Security Breach”) IDEAYA will send an e-mail to [***] notifying GSK, and upon discovering any suspected or actual Data Security Breach, GSK will send an e-mail to [***], notifying IDEAYA.  The Parties shall work with each other in good faith to identify a root cause and remediate the Data Security Breach.  

9.5

Press Releases and Other Public Statements.  Both Parties shall keep the terms of this Agreement confidential and such terms shall be treated as Confidential Information of both Parties in accordance with this ARTICLE 9 (and for clarity subject to Section 9.2), except that each Party may make the publications and presentations described in Sections 9.6 through 9.8 on the terms set forth therein, and each Party may (a) issue a public announcement of the execution of this Agreement in a form attached hereto as Schedule 9.5; (b) disclose the content of the Agreement to existing or prospective attorneys, auditors, advisors, consultants, contractors, existing or prospective collaboration partners, licensees, sublicensees, existing or prospective shareholders, investors, prospective acquirers, or prospective lenders for limited purposes under obligations of confidentiality and non-use no less restrictive than those in this Agreement; (c) disclose the content as necessary to subcontractors, sublicensees and other bona fide collaboration partners under obligations of confidentiality and non-use similar to those in this Agreement; or (d) as necessary as required by securities regulators, the rules of any stock exchange or as part of any listing of the securities of IDEAYA or GSK on any stock exchange.  Neither Party will use the other’s name or logo in any press release or product advertising, or for any other promotional purpose, without first obtaining the other's written consent and entering into appropriate trademark or housemark licenses, as applicable.  Any public announcement to be made in accordance with this Section 9.5 will be provided by the publishing Party to the other Party at least [***] days prior to its scheduled release; provided that, if the Party proposing such public announcement cannot provide the reviewing Party with [***] days’ notice due to extraordinary circumstances, such Party will use reasonable efforts to provide the reviewing Party with the proposed public statement for comment at least [***] hours before release. Notwithstanding the foregoing in this Section 9.5, a Party may make subsequent public announcements or press releases of solely of information previously publicly disclosed in accordance with this ARTICLE 9 without the advance written consent of the other Party, so long as (i) such subsequent public announcements or press releases are released without changes to the substantive information provided therein, (ii) are released within [***] months of the original release, and (iii) the information provided therein is still considered accurate and has not been superseded by other subsequent information known by IDEAYA.

9.6

For clarity, except as may be set forth in the MAT2A CTCSA, GSK shall not publish any information regarding the activities conducted under the MAT2A Program or during the Interim MAT2A Operating Period without the prior written approval of IDEAYA, and IDEAYA shall have the right to make such publications and other disclosures about its activities conducted under the MAT2A Program or Interim MAT2A Operating Period at its sole discretion.

9.6.1

If GSK or its employees or consultants (such as clinical investigators) wish to publish or publicly present any information about a Licensed Product or the results of any activities relating to the research or development of a Licensed Product, which publication contains any of IDEAYA’s Confidential Information, it shall deliver to IDEAYA a copy of the proposed written publication or an outline of an oral disclosure at least [***] days ([***] days in the case of abstracts) prior to submission for publication or presentation. IDEAYA shall respond in writing promptly and in no event later than [***] days ([***] days in the case of abstracts) after receipt of the proposed material, and may have the right to propose modifications to the publication or presentation for confidentiality reasons, or request a reasonable delay in publication or presentation in order to protect patentable information.  If IDEAYA requests a delay to protect patentable information, GSK shall delay submission or presentation for a period not to exceed [***] days to enable relevant patent applications to be filed. Upon expiration of such [***] days, GSK will be free to proceed with the publication or presentation. If IDEAYA reasonably requests modifications to the publication or presentation to prevent disclosure of IDEAYA Confidential Information, GSK shall edit such publication to prevent the disclosure of such information prior to submission of the publication or presentation.

9.6.2

Once a publication or presentation has been approved, GSK may use the information contained in the publication or presentation without seeking further approval.  

9.6.3

GSK will ascribe authorship of any proposed publication using accepted standards used in peer-reviewed, academic journals at the time of the proposed publication.

GSK Patents.  GSK shall have the right to pursue and direct, at its own cost and discretion, the preparation, filing, prosecution and maintenance of GSK Existing Patents and any other Patents Controlled by GSK and used in the performance of this Agreement excluding Subject Patents (the “GSK Patents”) and shall have no obligation to keep IDEAYA informed with respect to such activities.

10.2.4

Cooperation.  The Party that is not the Controlling Party will cooperate with the other Party, including furnishing a power of attorney, inventor declaration or assignment documentation, to allow such preparation, prosecution, maintenance or defense activities to be carried out effectively and expeditiously.  

10.3

Enforcement Rights

10.3.1

Notification of Infringement. If either Party learns of any infringement or threatened or suspected infringement, or misappropriation or threatened or suspected misappropriation, of any (a) IDEAYA Technology or GSK Technology by the manufacture, use, development or commercialization by a Third Party of a product that competes with a Licensed Product (a “Competing Product”) or (b) Joint Arising Technology, whether or not such Third Party infringement is by a Competing Product (each of (a) and (b), an “Infringement”), such Party shall promptly, but in any event within [***] days of becoming aware of such Infringement, provide notice to the Patent Liaisons describing such Infringement (each, an “Infringement Notice”) and, without limiting the foregoing, in the case of any certification filed

under the “U.S. Drug Price Competition and Patent Term Restoration Act of 1984” (the “Hatch-Waxman Act”) where a response is required under Applicable Law (in order to avoid waiving rights), such Party shall provide notice as quickly as possible and in no event later than [***] days prior to the applicable deadline for filing a response.  For clarity, any certification filed under the Hatch-Waxman Act shall constitute an Infringement for the purposes of this Agreement.

10.3.2

Enforcement and Recoveries.  

(a)

The Controlling Party shall have the initial right, but not the obligation, to pursue and direct enforcement of the applicable Subject Patent against such Infringement. If the Controlling Party decides not to abate such Infringement by way of enforcing one of more applicable Subject Patents against the relevant Third Parties, the Controlling Party shall inform the other Party of such decision in writing no later than [***] days after such Controlling Party first becomes aware of such Infringement. Upon receiving such notice from the Controlling Party, or if no such action to abate such Infringement is taken by the Controlling Party within such [***] day time period, the other Party shall thereafter immediately become deemed the Controlling Party for the purposes of this Section 10.3.2.  The Controlling Party will keep the other Party reasonably informed through the Patent Liaisons on a regular basis regarding, and provide such other Party with reasonable opportunity to consult and comment on, all enforcement activities in respect of the Subject Patents.  The non-Controlling Party shall have the right, to the extent permitted by Applicable Laws and procedural rules to join, at its own cost and using its own counsel, as a party to the enforcement actions included in such enforcement activities.  

(b)

GSK shall have the right to pursue and direct, at its own cost, enforcement of all GSK Patents.  Any damages or other monetary awards recovered from the settlement of or judgment from such enforcement actions shall be allocated to GSK.

10.3.3

Cooperation.  If the Controlling Party brings an enforcement action or proceeding in accordance with Section 10.3.2, then the other Party shall cooperate as reasonably requested in the pursuit of such enforcement action, including if necessary by joining as a party to any such enforcement action for which it is a necessary or indispensable party or taking such other actions as are necessary for standing, furnishing a power of attorney, or for the Controlling Party to otherwise maintain or pursue such enforcement action effectively and expeditiously.

10.3.4

Settlement with a Third Party. The Controlling Party that is controlling an enforcement action shall also have the right to control the settlement of such enforcement action; provided that the Controlling Party shall not settle such enforcement action in any way that imposes a monetary obligation upon the other Party or its Affiliates, or in any way that narrows the scope of, or admits the unenforceability or invalidity of Patents Controlled by the other Party or its Affiliates, or of Patents within the Joint Arising Technology, in all cases without such other Party’s prior written consent.

10.4

Infringement Claims by Third Parties.

10.4.1

Notice; Control.  Each Party shall promptly notify the other Party in writing of (a) any allegation by a Third Party that any Development, Manufacture or Commercialization or other activities with respect to any Licensed Product infringes or misappropriates or may infringe or misappropriate the intellectual property rights of such Third Party (a “Third Party Infringement Claim”).  Each Party shall have the right to control the defense of the Third Party Infringement Claim brought against such Party.

10.4.2

Cooperation; Settlement.  Each Party shall keep the other Party reasonably informed of all material developments in connection with any Third Party Infringement Claim through the Patent Liaisons.  Such Party shall provide the other Party with copies of all filings by or correspondence from the counterparty(ies) in any suit or proceeding relating to such Third Party Infringement Claim, and with copies of proposed filings to be filed or material correspondence to be delivered to such counterparty(ies) by the Party defending such Third Party Infringement Claim in such proceedings at least [***] days prior to the anticipated filing or delivery date thereof for the other Party to comment on, and the Party defending such Third Party Infringement Claim shall take all such comments received under good faith consideration.  The Party defending such Third Party Infringement Claim may enter into a settlement or compromise of any Third Party Infringement Claim, provided that, if such settlement or compromise would admit liability on the part of the other Party or any of its Affiliates or would otherwise have a material adverse effect on the rights or interests of the other Party or its Affiliates (including by imposing any monetary obligation upon the other Party or its Affiliates or by limiting the scope of or admitting the unenforceability or invalidity of Patents owned or exclusively licensed by the other Party or its Affiliates), then such Party shall not enter into such settlement or compromise without the prior written consent of the other Party.  Any counterclaims of Infringement shall be handled as set forth in Section 10.3.

10.4.3

Costs; Recoveries.  All out-of-pocket expenses incurred by a Party in defending a Third Party Infringement Claim (including outside counsel fees), and all amounts

payable by either Party as a judgment based on a Third Party Infringement Claim or in settlement of such Third Party Infringement Claim, shall be allocated as follows: (a) with respect to Third Party Infringement Claims directed to the activities conducted hereunder for the WRN Products or MAT2A Products in the Profit-Sharing Territory, so long as IDEAYA has not exercised the IDEAYA Opt-Out for the applicable Licensed Product, then in a manner consistent with the applicable split of Pre-Tax Profit and Loss, (b) with respect to Third Party Infringement Claims directed to the activities conducted hereunder for the WRN Products or MAT2A Products in the Net Sales Territory, then GSK shall be solely responsible for such costs, and (c) with respect to Third Party Infringement Claims directed to the activities conducted hereunder for the POLQ Products and Third Party Infringement Claims directed to the activities conducted hereunder for the WRN Products or MAT2A Products in the Profit-Sharing Territory if IDEAYA has exercised the IDEAYA Opt-Out for the applicable Licensed Product, GSK shall be solely responsible.

10.5

Orange Book.  GSK will have sole decision-making authority with respect to the determination of whether or not to submit IDEAYA Existing Patents, IDEAYA Arising Patents, Patents within the Joint Arising Technology, or any GSK Patent, in each case, which Patents claim or cover a POLQ Product, WRN Product, or, and solely as of and after the Option Closing Date, if applicable, the MAT2A Product to the applicable regulatory authorities for listing in the Orange Book as required under the Hatch-Waxman Act.

11.1

Term.  This Agreement shall become effective on the Effective Date and, unless earlier terminated pursuant to this ARTICLE 11, shall remain in effect until it expires (the “Term”) as follows:

11.1.1

on a Licensed Product–by–Licensed Product and country-by-country basis, this Agreement shall expire on the date of the expiration of all applicable Royalty Terms or Profit-Sharing Terms with respect to such Licensed Product in such country; and

11.1.2

this Agreement shall expire in its entirety upon the expiration of all applicable Royalty Terms and Profit-Sharing Terms under this Agreement with respect to all Licensed Products in all countries in the Territory.

11.1.3

Effect of Expiration.  After expiration of the Term with respect to any Licensed Product in a country pursuant to Section 11.1.1, or with respect to the Agreement in its entirety pursuant to Section 11.1.2, GSK shall have a non-exclusive, fully-paid, royalty-free right and license, with the right to grant sublicenses, under the IDEAYA Technology, to continue to make, have made, use, sell, offer to sell and import each Licensed Product in the Field in such country, or in the case of expiration of the Agreement in its entirety, all Licensed Products in the Field in all countries in the Territory, as applicable.

11.2

Termination for Cause.  In addition to any other remedies conferred by this Agreement or by Applicable Law or in equity, either Party may terminate this Agreement with

respect to Licensed Compounds or Licensed Products directed to a given Target on a per Target basis (e.g. POLQ, WRN, or, solely if the Option Closing Date occurs, MAT2A) if there is an uncured material breach of this Agreement by the other Party with respect to such Licensed Compounds or Licensed Products directed to such Target.  To exercise its termination rights under this Section 11.2, the non-breaching Party shall provide to the breaching Party with written notice, identifying the material breach in reasonable detail and whether the non-breaching Party is intending to terminate this Agreement with respect to the applicable Licensed Compounds or Licensed Products with respect to one or more Targets.  If such breaching Party, upon receiving such written notice identifying such material breach in reasonable detail, fails to cure such material breach within sixty (60) days after the date of such notice of breach is received (or if such breach is curable but cannot reasonably be cured within such sixty (60) day period, then within such reasonable period thereafter as is required to cure such breach), then this Agreement with respect to such particular Target against which the relevant Licensed Product and Licensed Compounds are directed shall terminate, unless there is a good faith dispute with respect to the existence of a material breach or whether such material breach has been cured, and if such alleged breach or failure to cure is contested in good faith by the alleged breaching Party in writing within sixty (60) days of the delivery of the breach notice, then the dispute resolution procedure pursuant to Section 15.1, may be initiated by either Party to determine whether a material breach or a failure to cure has actually occurred.  If either Party so initiates the dispute resolution procedure, then the applicable cure period (and the corresponding termination of this Agreement, in whole or in part), shall be tolled until such time as the dispute is resolved pursuant to Section 15.1.

11.3

Termination by GSK for Convenience.  GSK shall have the right, at its sole discretion, exercisable at any time during the Term to terminate this Agreement with respect to one or more Targets against which the relevant Licensed Compounds or Licensed Products upon ninety (90) days prior written notice to IDEAYA hereunder.  In addition, GSK shall have the right, at its sole discretion, exercisable at any time during the Term to terminate this Agreement in its entirety upon ninety (90) days prior written notice to IDEAYA hereunder.

11.4

Termination for Insolvency.  Either Party may terminate this Agreement in its entirety, effective immediately upon written notice to the other Party if, at any time such other Party (or any Affiliate that controls such Party) (a) files in any court or agency pursuant to any statute or regulation of any state or country a petition in bankruptcy or insolvency or for reorganization (except for solvent reorganization or solvent reconstruction) or for an arrangement or for the appointment of a receiver or trustee of the Party or of substantially all of its assets, (b) proposes a written agreement of composition or extension of substantially all of its debts, (c) is served with an involuntary petition against it, filed in any insolvency proceeding, and such petition is not be dismissed within ninety (90) days after the filing thereof, (d) proposes to be a party to any dissolution or liquidation, (e) admits in writing its inability generally to meet its obligations as they fall due in the general course or (f) makes an assignment of substantially all of its assets for the benefit of creditors.

11.5

Termination for Patent Challenge.  Except to the extent that this Section 11.5 is unenforceable under the law of the applicable jurisdiction where the applicable Patent is pending or issued, if GSK, its Affiliates, or its Sublicensees directly asserts in its own respective

name, or directs a Third Party to assert, an action challenging the validity, scope, or enforceability of any Patent within the IDEAYA Technology with respect to a Target (including a Licensed Compound or Licensed Product relating to such Target) (including for clarity within the relevant Joint Arising Technology) that is then exclusively licensed to GSK under this Agreement (each, a “Patent Challenge” relating to such Target), IDEAYA may terminate this Agreement with respect to such Target (and all Licensed Compounds and Licensed Products relating to such Target) upon thirty (30) days’ written notice to GSK if GSK does not withdraw, or cause to be withdrawn, such Patent Challenge within such thirty (30) day period.  Further, this Section 11.5 shall not apply to any Affiliates of GSK that first become Affiliates of GSK after the Effective Date in connection with a merger or acquisition event, where such Affiliates of GSK were already engaged in a Patent Challenge prior to such merger or acquisition event, so long as GSK causes such Patent Challenge to terminate within sixty (60) days after such merger or acquisition event.

12.1

Accrued Obligations.  Expiration or termination of this Agreement (in whole or in part) for any reason shall not release either Party from any liability that, at the time of such expiration or termination, has already accrued to the other Party or that is attributable to a period prior to such expiration or termination, nor will any early termination of this Agreement preclude either Party from pursuing any and all rights and remedies it may have under this Agreement, or at law or in equity, with respect to breach of this Agreement.

12.2

Effects of Termination by GSK for Convenience, or by IDEAYA for GSK Insolvency or Material Breach or Patent Challenge.  If (x) this Agreement is terminated by IDEAYA in its entirety or with respect to one or more Targets against which the relevant Licensed Compounds or Licensed Products are directed as a result of GSK’s uncured material breach, GSK’s bankruptcy, or a Patent Challenge or (y) GSK terminates this Agreement in its entirety or with respect to one or more Collaboration Programs or Licensed Products for convenience (upon any termination under the foregoing clause (x) or (y), then all such terminated Licensed Compounds and Licensed Products directed to such Target shall be deemed “Terminated Compounds” and “Terminated Products”, respectively), and the following will apply:

12.3

Effects of IDEAYA Material Breach.  

12.3.1

In the event GSK has the right under Section 11.2 to terminate this Agreement in its entirety or with respect to one or more Licensed Compounds or Licensed Products as a result of IDEAYA’s uncured material breach, and GSK elects to terminate this Agreement or with respect to such applicable Licensed Compounds or Licensed Products, then all licenses granted to GSK under Sections 8.1 or 8.2, as applicable, either in their entirety (if applicable) or only with respect to such Terminated Compounds and Terminated Products, shall be terminated and of no further force and effect.

12.3.2

Further, in the event IDEAYA materially breaches any of its obligations under Section 3.2 and fails to cure such material breach within sixty (60) days after the date of such notice of material breach is received (or if such material breach is curable but cannot reasonably be cured within such sixty (60) day period, then within such reasonable period thereafter as is required to cure such material breach), [***].  GSK may, at its election, with notice of its election but without demand, [***].  If IDEAYA desires to contest GSK’s assertion of any such material breach of Section 3.2 as described under this Section 12.3.2 [***], IDEAYA may elect to initiate dispute resolution under ARTICLE 15 with respect to such matters, but no such election by IDEAYA shall toll or otherwise prevent GSK from exercising its right to take the actions, in accordance with this Section 12.3.2, [***].

12.4

Effects of Expiration of the Exercise Period or Non-Occurrence of Option Closing Date.   In the event that the Agreement is terminated with respect to the MAT2A Target because GSK does not exercise the Option within the Exercise Period, or because the Option Closing Date does not occur, GSK shall have no rights or obligations whatsoever under this Agreement or under any Patents, Know-How, or other intellectual property Controlled by IDEAYA or its Affiliates (including IDEAYA Technology) to make, have made, use, sell, offer for sale and import, or otherwise exploit any MAT2A Compound or MAT2A Product, and, subject to Section 12.7, all other rights with respect to MAT2A Compounds or MAT2A Products set forth in this Agreement, including Section 2.3, shall be terminated.

12.5

Unaffected Programs or Products.  If this Agreement is terminated only with respect to a particular Target or Targets, then all unaffected Licensed Compounds and Licensed Products shall remain in effect in accordance with and subject to the terms and conditions of this Agreement.  Without limiting the foregoing, the rights granted by each Party to the other Party with respect to such Licensed Compounds and Licensed Product that are not subject to the

termination, shall remain in effect, in accordance with and subject to terms and conditions of this Agreement.

12.6

Return of Confidential Information.  At the written request of the Disclosing Party promptly following the termination of this Agreement, the Receiving Party shall (and shall cause its Affiliates and their respective representatives to) return to the Disclosing Party or destroy all originals of documents (in paper or electronic form) and physical materials then in its possession, and copies thereof, containing Confidential Information received from the Disclosing Party and constituting its exclusive Confidential Information, and destroy all documents and other materials that it created including any such Confidential Information; provided that the Receiving Party may retain in confidence (a) one (1) archival copy of the Confidential Information in its legal files solely to permit the Receiving Party to determine compliance with its obligations hereunder; (b) any portion of the Confidential Information of the other Party which is contained in the Receiving Party’s laboratory notebooks or automatic computer backups; (c) any portion of the Confidential Information of the other Party which a Receiving Party is required by Applicable Law to retain; and (d) any Confidential Information that the Receiving Party has the right to continue to use after the date of the Disclosing Party’s request after termination or expiration of this Agreement, as applicable. Notwithstanding the return or destruction of the documents and tangible items described above, the Parties will continue to be bound by their obligations under ARTICLE 9.
