and 
 (c) In the event that Licensor shall fail to make any payment when due or any other default or breach arises under any Third
Party License Agreement, unless and until a Third Party License Agreement provides (or Licensor enters into a written agreement, including an amendment to such Third Party License Agreement, providing) that Company’s rights under such Third
Party License Agreement granted hereunder would survive any termination of such Third Party License Agreement, Company shall have the right (but not the obligation) to make such payment or otherwise cure such default or breach on behalf of Licensor.
In such event, Licensor shall promptly

reimburse Company any such amounts paid and/or costs and expenses incurred by Company or, at Company’s election, Company may offset such amounts paid and/or costs and expenses incurred by
Company against any amounts payable to Licensor hereunder, provided that, if Licensor in good faith disputes any such breach or termination right and is contesting such breach or termination right pursuant to the terms of the applicable Third

	  	Percentage	 
	 $[***] - $[***]
	  	 	[***]	% 
	 $[***] - $[***]

 CONFIDENTIAL 
  

 For example, if annual Net Sales of a Product in a country is $3,800,000,000, then the
royalty payable by Company to Licensor would be calculated as [***]. The royalty payments described above will apply even if the Products are used for targets other than C-KIT or HPK1. 

 

	5.3	 Reductions and Deductions. 



(a) Anti-Stacking. If Company or any of its Affiliates or Sublicensees enter into a Third Party License Agreement, including in
connection with a settlement of any Third Party Action, Company will be entitled to deduct [***] percent ([***]%) of the analogous amounts paid by Company, its Affiliates or Sublicensees pursuant to such Third Party License Agreement(s) from any
amounts due to Licensor pursuant to Section 5.2, until such amounts have been fully deducted. Notwithstanding the foregoing, under no circumstances shall the deductions under this Section 5.3(a) result in the amount payable to Licensor
being reduced by more than [***] percent ([***]%) compared with the amount otherwise payable under Section 5.2. In the event that Company is not able to deduct the full amount of the permitted deduction from the amount due to Licensor due to
the [***] percent ([***]%) minimum amount, Company shall be entitled to deduct any undeducted excess amount from subsequent amounts owed to Licensor under Section 5.2 (subject always to Licensor receiving a minimum of [***] percent ([***]%) of
the amount owed). 
 (b) Generic Competition. On a
Product-by-Product basis, the royalty rates set forth in Section 5.2 for Net Sales of a Product in a country of the Territory shall be reduced by [***] percent
([***]%) beginning upon the occurrence of a Generic Competition Triggering Event with respect to such Product in such country if the average Net Sales by Licensee and its Affiliates and Sublicensees of such Product in such country in any [***]
([***]) consecutive Calendar [***] are at least [***] percent ([***]%) lower, but no more than [***] percent ([***]%) lower, than the average Net Sales by Licensee and its Affiliates and Sublicensees for such Product in such country during the [***]
([***]) full Calendar [***] immediately prior to launch of the Generic Product in such country. On a Product-by-Product basis, the royalty rates set forth in
Section 5.2 for Net Sales of a Product in a country of the Territory shall be reduced by [***] percent ([***]%) beginning upon the occurrence of a Generic Competition Triggering Event with respect to such Product in such country if the average
Net Sales by Licensee and its Affiliates and Sublicensees of such Product in such country in any [***] ([***]) consecutive Calendar [***] are more than [***] percent ([***]%) lower than the average Net Sales by Licensee and its Affiliates and
Sublicensees for such Product in such country during the [***] ([***]) full Calendar [***] immediately prior to launch of the Generic Product in such country. 

(c) Cumulative. The reductions and deductions set forth in this Section 5.3 are cumulative and shall apply, in each case, to
the maximum extent applicable. 
  

	5.4	 Mode of Payment and Currency; Invoices. All payments to Licensor hereunder shall be made by deposit of
US Dollars in the requisite amount to such bank account as Licensor may from time 



  
 15 














 CONFIDENTIAL 
  


	 	
to time designate by written notice to Company. With respect to amounts payable hereunder not denominated in US Dollars, Company shall convert applicable amounts in foreign currency into US
Dollars by using an exchange rate equal to the monthly average exchange rate between each currency of origin and US Dollars as reported by the Wall Street Journal, Eastern Edition for the month in which the applicable sales occurred. The monthly
average exchange rate shall be the average of (i) the exchange rate published on the last day of the calendar month and (ii) the exchange rate published on the last day of the preceding calendar month. Based on the resulting sales in US
Dollars, the then-applicable royalties shall be calculated. The Parties may vary the method of payment set forth herein at any time upon mutual written agreement, and any change shall be consistent with the local Law at the place of payment or
remittance. 

  

	5.5	 Reports and Records Retention. Within [***] ([***]) days after the end of each Calendar Quarter during
which any payment under Section 5.2 becomes payable, Company shall deliver to Licensor, a written report (“Royalty Report”), on a
Product-by-Product, country-by-country basis, summarizing the total amount of the gross
sales (to the extent recognized as gross revenue by Licensee or any of its Affiliates or Sublicensees on an accrual basis in accordance with US GAAP or IFRS, depending on which accounting standard is normally applied by such party with respect
to the filing of its reporting) resulting from the sale of Products sold by Company, its Affiliates and its Sublicensees and Net Sales during such Calendar Quarter, the exchange rates used in converting Net Sales to U.S. dollars, and details on a country-by-country basis of any deductions or reductions pursuant to Section 5.3 and the calculation of the Royalty Payment, and the dates of the First Commercial Sale of
each Product in each country in the Territory for which royalties are due hereunder, if it has occurred during the corresponding Calendar Quarter. The Company shall pay all amounts due to Licensor pursuant to Section 5.2 with respect to Net
Sales for each Calendar Quarter within [***] ([***]) days after the end of each Calendar Quarter. Each Royalty Report shall be deemed Confidential Information of Company subject to the obligations of Article 7 of this Agreement. For at least [***]
([***]) years after the end of the Calendar Year in which any such Royalty Report is submitted, Company shall, and shall ensure that its Affiliates, keep complete and accurate records of such Net Sales in sufficient detail to confirm the accuracy of
the calculations hereunder. 


  

	5.6	 Late Payments. All payments under this Agreement which are not disputed in good faith by Company shall
earn interest from the date due until paid at a rate equal to the lesser of (a) the maximum rate permissible under Law and (b) one percent (1.0%) percent per month (i.e., twelve percent (12%) per annum). 



 

	5.7	 Audits. 



(a) Audits Generally. During the Term and for [***] ([***]) [***] thereafter, and not more than once in each Calendar Year per
entity audited, Company shall permit, and shall cause its Affiliates to permit, an independent certified public accounting firm of nationally recognized standing selected by Licensor, and reasonably acceptable to Company or such Affiliate, to have
access to and to review, during normal business hours upon reasonable prior written notice, the applicable records of Company and its Affiliates to verify the accuracy of the Royalty Reports and payments under this Article 5. Such review may cover
the records for sales made in any Calendar Year ending not more than [***] ([***]) months prior to the date of such request. The accounting firm shall disclose to Licensor and Company only whether the Royalty Reports are correct or incorrect and the
specific details concerning any discrepancies. No other information shall be provided to Licensor. 
 (b) Audit-Based
Reconciliation. If such accounting firm concludes that additional amounts 

  
 16 














 CONFIDENTIAL 
  

 
were owed during such period, and Company agrees with such calculation, Company shall pay the additional undisputed amount within [***] ([***]) days after the date Licensor delivers to Company
such accounting firm’s written report. If such accounting firm concludes that an overpayment was made, such overpayment shall be fully creditable against amounts payable in subsequent payment periods. If Company disagrees with such calculation,
it may retain its own independent certified public accounting firm of recognized standing and reasonably acceptable to Licensor, to conduct a review, and if such firm concurs with the other accounting firm, Company shall make the required payment
within [***] ([***]) days after the date Company receives the report of its accounting firm. Licensor shall pay for the cost of any audit, unless Company has underpaid Licensor by [***] percent ([***]%) or more for the audited period. 

(c) Audit Confidentiality. Each Party shall treat all information that it receives under this Section 5.7 in accordance with
the confidentiality provisions of Article 7 of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with the other Party obligating such firm to retain all such financial information in confidence
pursuant to such confidentiality agreement, except to the extent necessary for such Party to enforce its rights under this Agreement. 
  

	5.8	 Taxes. 



(a) Withholding Tax. Licensor shall be responsible for the payment of any and all Taxes levied on account of the payments paid to
Licensor by Company or its Affiliates or Sublicensees under this Agreement. If Law requires that Taxes be deducted and withheld from payments paid under this Agreement, Company shall (i) deduct those Taxes or other payment owed by Company
hereunder; (ii) pay the Taxes to the proper Governmental Body; (iii) send evidence of the obligation together with proof of Tax payment to Licensor within [***] ([***]) days following such payment; (iv) remit the net amount, after
deductions or withholding made under this Section 5.8(a); and (v) cooperate with Licensor in any way reasonably requested by Licensor, to obtain available reductions, credits or refunds of such Taxes; provided, however, that Licensor shall
reimburse Company for Company’s Out-of-Pocket Expenses incurred in providing such assistance. 

(b) Value Added Tax. Unless otherwise required by applicable Law, all consideration payable under this Agreement shall be
exclusive of VAT. If a Party makes a supply pursuant to this Agreement, and VAT is payable on that supply, the consideration for the supply (VAT exclusive consideration) is increased by an amount equal to the VAT exclusive consideration multiplied
by the rate of VAT prevailing at the time the supply is made (additional VAT amount). VAT (if any) will become due and payable upon presentation of a valid VAT invoice (or, where there is no provision in the legislation for the jurisdiction
concerned that a VAT invoice is required to be issued, a written demand containing such information as is customary in that jurisdiction). 

(c) Assignment. If Company assigns its rights and obligations hereunder to an Affiliate or Third Party in compliance with
Section 12.2 and if such Affiliate or Third Party shall be required by Law to withhold any additional Taxes from or in respect of any amount payable under this Agreement as a result of such assignment, and except to the extent that, pursuant to
Section 5.8(a), such Taxes were required to be withheld or deducted by the Company, then any such additional amount, in excess of the amounts withheld or deducted by the Company, payable under this Agreement shall be increased to take into
account the additional Taxes withheld as may be necessary so that, after making all required withholdings, Licensor receives an amount equal to the sum it would have received had no such assignment been made. For the avoidance of doubt, if Licensor
assigns its right and obligations under this Agreement in compliance with Section 12.2, Licensor shall not be entitled to any additional payments with respect to Taxes arising as a result of Licensor’s assignment.

Licensor’s sole discretion and cost, provided, however, that Company will have no further right or licenses hereunder with respect to such Licensor Patent. If Licensor elects to continue prosecution or maintenance of any such Patent Rights,

Licensor, to the extent reasonably necessary to enable Licensor to continue prosecution or maintenance of any such Patent Rights in such country. With respect to Non-Exclusive Licensor Patents, if Licensor

In such case, Company shall have the right to support the continued prosecution or maintenance of such Non-Exclusive Licensor Patent in that country at Company’s sole discretion and cost, provided,
however, that Licensor will have no further right with respect to such Non-Exclusive Licensor Patent and Company’s rights and licenses with respect to such
Non-Exclusive Licensor Patent shall automatically become exclusive (even as to Licensor and its Affiliates). 

(d) Patent Term Extension. Company shall be responsible, in Licensor’s name, on a worldwide basis, for making decisions
regarding and obtaining patent term extensions wherever available for Licensor Patents. Licensor shall provide Company free-of-charge with all relevant information,
documentation and assistance in this respect as may reasonably be requested by Company. Any such assistance, supply of information and consultation shall be provided promptly and in a reasonable manner. In the event that any election with respect to
obtaining patent term extensions is to be made, Company shall have the right to make such elections, and Licensor shall abide by all such elections. Company shall keep Licensor informed of the status of any efforts regarding patent term extensions
in a timely manner. 
 (e) Company Patents. Company shall own any Know-How developed
solely by Company or any of its Affiliates or a Third Party on behalf of Company and shall have the right, but not the obligation, to file, prosecute and maintain Patent Rights claiming any such Know-How
(collectively, “Company Patents”). Company shall bear all costs and expenses of filing, prosecuting and maintaining Company Patents and Licensor shall have no particular rights with respect thereto unless otherwise agreed upon by
the Parties in writing. 
  

	6.4	 Enforcement of Patents and Know-How. 



(a) Notice. If either Party believes that an infringement, unauthorized use, misappropriation or ownership claim or threatened
infringement or other such activity by a Third Party with respect 

  
 19 














 CONFIDENTIAL 
  

 
to any Exclusive Licensor Technology or Non-Exclusive Licensor Patents or if a Third Party claims that any Exclusive Licensor Patent or Non-Exclusive Licensor Patent is invalid or unenforceable (any such activity by a Third Party, a “Third Party Infringement”), the Party possessing such knowledge or belief shall notify the other
Party and provide it with details of such infringement or claim that are known by such Party. 
 (b) Right to Bring an Action.
Company shall have the exclusive right to attempt to resolve any Third Party Infringement in the Territory, including by filing an infringement suit, defending against such claim or taking other similar action, with respect to an Exclusive Licensor
Patent or Non-Exclusive Licensor Patent (each, an “Action”) and to compromise or settle any such infringement or claim. At Company’s request, Licensor shall promptly provide Company with
all relevant documentation (as may be reasonably requested by Company) evidencing that Company is validly empowered by Licensor to take such an Action. Licensor may voluntarily join such Action, however, Company may not, without Licensor’s
prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, join Licensor as a party in any Action initiated by the Company, pursuant to Company’s rights under this Agreement to initiate such Action.
Notwithstanding the foregoing, in the event that it is required under applicable law in order for Company to initiate an Action under this Section 6.4(b), then Licensor shall join as a party to such Action. If Company does not intend to
prosecute or defend an Action, Company shall promptly inform Licensor and Licensor shall have the right, but not the obligation, to initiate an Action. The Party controlling the Action (i) shall keep the other Party reasonably informed with
respect to such Action, (ii) shall, in good faith, consult with, and give reasonable consideration to, any comments made by the other Party related to such Action, and (iii) shall provide the other Party with copies of all material
documents (e.g., complaints, answers, counterclaims, material motions, orders of the court, memoranda of law and legal briefs, interrogatory responses, depositions, material pre-trial filings, expert
reports, affidavits filed in court, transcripts of hearings and trial testimony, trial exhibits and notices of appeal) filed in, or otherwise relating to, such Action. The Parties shall cooperate in good faith to ensure that each person or entity
that participates in, or receives any information about, any Action in accordance with this Section 6.4(b) shall use reasonable efforts to protect all applicable confidential information and preserve all applicable attorney-client privilege and
work product protections. 
 (c) Costs of an Action. Subject to the respective indemnity obligations of the Parties set forth
in Article 9, the Party initiating an Action under Section 6.4(b) shall pay all costs associated with such Action, and shall reimburse the other Party for reasonable
Out-of-Pocket Expenses incurred in rendering assistance to the initiating Party as set forth in Section 6.4(e). For clarity, the other Party shall have the right to
join and participate in an Action relating to a Licensor Patent, and be represented in any such Action by its own counsel at its own expense. 

(d) Settlement. Neither Party shall settle or otherwise compromise any Action by admitting that any Exclusive Licensor Patent or Non-Exclusive Licensor Patent is invalid or unenforceable without the other Party’s prior written consent, and neither Party may settle or otherwise compromise an Action in a way that adversely affects or would
be reasonably expected to materially adversely affect the validity or enforceability of the Exclusive Licensor Patents, the Non-Exclusive Licensor Patents or the rights or benefits of the other Party
hereunder, without the other Party’s prior written consent. The foregoing shall not limit Company’s rights under Section 6.4(b). 

(e) Reasonable Assistance. The Party not enforcing or defending Exclusive Licensor Patents or
Non-Exclusive Licensor Patents shall provide reasonable assistance to the other Party, including providing access to relevant documents and other evidence and making its employees available, subject to the
other Party’s reimbursement of any reasonable Out-of-Pocket Expenses incurred on an on-going basis by the non-enforcing or non-defending Party in providing such assistance. 

  
 20 














 CONFIDENTIAL 
  

 (f) Distribution of Amounts Recovered. Any amounts recovered by the Party
taking an Action pursuant to this Section 6.4, whether by settlement or judgment, shall be allocated in the following order: (i) to reimburse the Party taking such Action for any costs, including Out-of-Pocket Expenses incurred; (ii) to reimburse the Party not taking such Action for costs incurred by it at the request of the Party taking such Action (to the extent that such costs have not been
previously reimbursed); and (iii) the remaining amount of such recovery shall be allocated to Company and deemed to be Net Sales in the Calendar Quarter in which the amount is received by Company, which shall be included in the Royalty Payment
under Section 5.2. 
 (g) Company Patents. Company shall have the sole right and authority, but not the obligation, to
enforce Company Patents against any Third Party infringer. 
 (h) Delegation of Enforcement Rights. Company shall have the
right, in its sole discretion, to delegate its rights under this Section 6.4, in whole or in part, to any of its Affiliates or one or more Sublicensees, provided that any such Affiliate or Sublicensee shall comply with the terms of this
Section 6.4. 
  

	6.5	 Third Party Actions Claiming Infringement. 



(a) Notice. If a Party becomes aware of any Third Party Action, such Party shall promptly notify the other Party of all details
regarding such claim or action that is reasonably available to such Party. 
 (b) Right to Defend. Company shall have the
right, at its sole expense, but not the obligation to defend the Third Party Action in the Territory described in Section 6.5(a) and to compromise or settle such Third Party Action. If Company declines or fails to assert its intention to defend
such Third party Action within [***] ([***]) days after sending (in the event that Company is the notifying Party) or receiving (in the event that Licensor is the notifying Party) notice under Section 6.5(a), then Licensor shall have the right
to defend such Third Party Action. The Party defending such Third Party Action shall have the sole and exclusive right to select counsel for such Third Party Action. 

(c) Consultation. The Party defending a Third Party Action pursuant to Section 6.5(b) shall be the “Controlling
Party.” The Controlling Party shall consult with the non-Controlling Party on all material aspects of the defense. The non-Controlling Party shall have a
reasonable opportunity for meaningful participation in decision-making and formulation of defense strategy. The Parties shall reasonably cooperate with each other in all such actions or proceedings. The
non-Controlling Party will be entitled to be represented by independent counsel of its own choice at its own expense. 

(d) Appeal. In the event that a judgment in a Third Party Action is entered against the Controlling Party and an appeal is
available, the Controlling Party shall have the first right, but not the obligation, to file such appeal. In the event the Controlling Party does not desire to file such an appeal, it will promptly, in a reasonable time period (i.e., with sufficient
time for the non-Controlling Party to take whatever action may be necessary) prior to the date on which such right to appeal will lapse or otherwise diminish, permit the
non-Controlling Party to pursue such appeal at such non-Controlling Party’s own cost and expense. If Law requires the other Party’s involvement in an appeal,
the other Party shall be a nominal party of the appeal and shall provide reasonable cooperation to such Party at such Party’s expense. 

  
 21 














 CONFIDENTIAL 
  

 (e) Costs of an Action. Subject to the respective indemnity obligations of the
Parties set forth in Article 9, the Controlling Party shall pay all costs associated with such Third Party Action other than the expenses of the other Party if the other Party elects to join such Third Party Action (as provided in the last sentence
of this paragraph); provided, that, without limitation of Licensor’s indemnification obligations under Article 9, each Party shall have the right to join a Third Party Action defended by the other Party, at its own expense. 

(f) No Settlement without Consent. Neither Party shall settle or otherwise compromise any Third Party Action by admitting that
any Exclusive Licensor Patent or Non-Exclusive Licensor Patent is invalid or unenforceable or in a manner that adversely affects or would be reasonably expected to materially adversely affect any rights or
benefits of the other Party without the other Party’s prior written consent. The foregoing shall not limit Company’s rights under Section 6.5(b). 

ARTICLE 7

	7.1	 Confidentiality Obligations. Each Party agrees that, for the Term and for [***] ([***]) years
thereafter, such Party shall, and shall ensure that its Affiliates and its and their employees, consultants, contractors, advisors and agents (collectively, “Representatives”), hold in confidence all Confidential Information
disclosed to it by the other Party pursuant to this Agreement, unless such information: 


 (a) is or becomes
generally available to the public other than as a result of improper disclosure by the recipient; 
 (b) is already known by or in the
possession of the recipient at the time of disclosure by the disclosing Party; 
 (c) are permitted to be disclosed by prior written
consent of the disclosing Party; 
 (d) is independently developed by recipient without use of or reference to the disclosing
Party’s Confidential Information; or 
 (e) is obtained by recipient from a Third Party that has not breached any obligations of
confidentiality. 
 The recipient shall not disclose any of the Confidential Information, except to Representatives of the recipient who need
to know the Confidential Information for the purpose of performing the recipient’s obligations, or to assist recipient in exercising its rights, under this Agreement and who are bound by obligations of
non-use and non-disclosure substantially similar to those set forth herein. The recipient shall be responsible for any disclosure or use of the Confidential Information
by such Representatives. The recipient shall protect Confidential Information using not less than the same care with which it treats its own confidential information, but at all times shall use at least reasonable care. 

 

	7.2	 Permitted Use/Disclosure. Notwithstanding Section 7.1, a Party may use or disclose the
Confidential Information of the other Party for the purpose of performing its obligations, or exercising its rights, under this Agreement, including for purposes of: 



(a) filing or prosecuting patent applications, pursuant to the terms of Section 6.3; 

  
 22 














 CONFIDENTIAL 
  

 (b) prosecuting or defending litigation; 

(c) conducting pre-clinical studies or Clinical Trials pursuant to this Agreement; 

(d) seeking or maintaining Regulatory Approval of any Product; or 

(e) complying with Law, including securities Law and the rules of any securities exchange or market on which a Party’s securities

 In addition to the foregoing, Company may, in connection with performing its obligations or exercising its rights
under this Agreement, disclose Confidential Information of Licensor to its actual or potential partners, acquirers, financing sources, licensees, Sublicensees, research collaborators, employees, consultants, and agents, and Licensor may, in
connection with exercising its rights under this Agreement, disclose Confidential Information of Company which Company has provided to Licensor in connection with its performance of its obligations under this Agreement to Licensor’s employees,
consultants, agents, and actual or potential acquirers or financing sources, each of whom prior to disclosure must be bound by similar obligations of confidentiality and non-use as those set forth in this
Article 7. The recipient shall be responsible for any disclosure or use of the Confidential Information by such persons to whom it discloses Confidential Information pursuant to this paragraph. 

In connection with any permitted filing by either Party of this Agreement with any Governmental Body the filing Party shall endeavor to obtain
confidential treatment of economic, trade secret information and such other information as may be requested by the other Party, and shall provide the other Party with the proposed confidential treatment request within a reasonable time for the other
Party to provide comments, and the filing Party shall consider such comments in good faith in connection with its submission of its confidential treatment request. 
  

	7.3	 Required Disclosure. The recipient may disclose the Confidential Information to the extent required by
Law or court order; provided, however, that the recipient promptly provides to the disclosing party prior written notice of such disclosure and provides reasonable assistance to the disclosing party in obtaining an order or other remedy protecting
the Confidential Information from public disclosure. 


  

	7.4	 Publications. Licensor shall not publish, present, announce results or otherwise disclose any
information relating to any Compound or Product without first obtaining the prior written consent of Company (which consent shall not be unreasonably withheld, delayed or conditioned), unless such information has already been publicly disclosed
either prior to the Effective Date or after the Effective Date through no fault of Licensor and otherwise not in violation of this Agreement. Licensor shall submit to Company for Company’s written approval (which approval shall not be
unreasonably withheld, delayed or conditioned) any publication or presentation (including in any seminars, symposia or otherwise) of information related directly or indirectly to any Compound or Product for review and approval at least [***] ([***])
days prior to submission for the proposed date of publication or presentation. Company shall have the right to publish, present, announce results or otherwise disclose any information relating to any Compound or Product without the prior written
consent of Licensor. If either party is planning to publish any scientific publications that include any material information directly relating to any compound in Chemical Library I (the “Chemical Library I Publications”), then such
publishing Party shall provide a copy of such proposed publication to the other Party so as to give the other Party [***] ([***]) days to comment on such publication. The foregoing obligation (in the last sentence) shall not apply to the extent such
material information has already been publicly disclosed through no fault of the publishing 



  
 23 














 CONFIDENTIAL 
  


	 	
Party or in violation of this Agreement. The publishing Party shall consider in good faith the comments or proposed changes made by the other Party on any Chemical Library I Publication and shall
agree to designate employees or others acting on behalf of the other Party as co-authors on any publication describing results to which such persons have contributed in accordance with standards applicable to
authorship of scientific publications. If the other Party reasonably determines that the Chemical Library I Publication would entail the public disclosure of such other Party’s Confidential Information or of a patentable invention upon which a
patent application should be filed prior to any such disclosure, submission of the concerned publication to Third Parties shall be delayed for such period as may be reasonably necessary for deleting any such Confidential Information of the other
Party (if the other Party has requested deletion thereof from the proposed Chemical Library I Publication), or the drafting and filing of a patent application covering such invention, provided such additional period shall not exceed [***] ([***])
calendar days from the date the publishing Party first provided the proposed publication to the other Party. Notwithstanding anything to the contrary in the foregoing, with respect to any publications by investigators or other Third Parties, such
materials shall be subject to review under this Section 7.4 only to the extent that a Party has the right and ability (after using Commercially Reasonable Efforts) to do so. In addition, for the sake of clarity, in no event shall the
Parties’ rights with respect to Chemical Library I Publications limit in any manner any of Company’s rights to publish, present, announce results or otherwise disclose any information relating to any Compound or Product without the prior
written consent of Licensor. 

  

	7.5	 Public Disclosures. Neither Party shall have the right to make press releases or public announcements
regarding this Agreement or the terms of this Agreement without first obtaining the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed, except for disclosures made in compliance with

Section 12.7) that the Compound and/or Product were licensed in from an unaffiliated entity, without the prior written consent of Licensor.

Commercialization, manufacturing or other activities in connection with the use or practice of the Exclusive Licensor Technology or Non-Exclusive Licensor Patents by or on behalf of Company or its Affiliates
or Sublicensees (including product liability claims); provided, however, that Company’s obligations pursuant to this Section 9.1 shall not apply (i) to the extent such claims or suits arise or result from the negligence or willful
misconduct of any of the Licensor Indemnitees or are covered by Licensor’s obligations under Section 9.2, (ii) with respect to claims or suits arising out of breach by Licensor of any of its representations or warranties forth in Article 8
or (iii) with respect to any personal injury claims or suits resulting directly from the use of any Lead Candidates or Chemical Library I supplied to Company by Licensor. 



 

	9.2	 Indemnification by Licensor. Licensor shall indemnify, defend and hold Company and its Affiliates and
each of their respective agents, employees, officers and directors (“Company Indemnitees”) harmless from and against any and all Third Party liability, damage, loss, cost or expense (including reasonable attorney’s fees) to the
extent arising out of Third Party claims or suits (including Third Party Actions) related to: (a) Licensor’s negligence or willful misconduct; or (b) breach by Licensor of its representations, warranties or covenants set forth in this
Agreement; or (c) Development, Commercialization, manufacturing or other activities in connection with the use or practice of the Non-Exclusive Licensor Patents by or on behalf of Licensor or its

misconduct of any of Company Indemnitees or are covered by Company’s obligations under Section 9.1 or (ii) with respect to claims or suits arising out of a breach by Company of its representations or warranties set forth in Article 8.



  

	9.3	 No Consequential Damages. EXCEPT (A) IN THE EVENT OF THE WILLFUL MISCONDUCT OR FRAUD OF A
PARTY, (B) OR A PARTY’S BREACH OF ITS OBLIGATIONS UNDER ARTICLE 7 (CONFIDENTIALITY), AND (C) TO THE EXTENT ANY SUCH DAMAGES ARE REQUIRED TO BE PAID TO A THIRD PARTY WITH RESPECT TO EACH PARTY’S INDEMNIFICATION OBLIGATIONS UNDER

reasonably cooperate with the other Party and its counsel in the course of the defense of any such suit, claim or demand, such cooperation to include using reasonable efforts to provide or make available documents, information and witnesses. The
indemnifying Party shall have no liability under this Article 9 with respect to claims or suits settled or compromised without its prior written consent. The assumption of the defense of a claim or suit by the indemnifying Party shall not be
construed as an acknowledgment that the indemnifying Party is liable to indemnify the indemnified Party in respect to such claim or suit, nor shall it constitute a waiver by the indemnifying Party of any defenses it may assert against the
indemnified Party’s claim for indemnification. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless the indemnified Party from and against the suit or claim, the
indemnified Party shall reimburse the indemnifying Party for any and all costs and expenses (including attorneys’ fees and costs of suit) and any liabilities incurred by the indemnifying Party in its defense of such claim or suit.

that this insurance shall not be construed to limit either Party’s liability with respect to its indemnification obligations hereunder or otherwise. Each Party will, except to the extent self-insured, provide to the other Party upon request a
certificate evidencing the insurance such Party is required to obtain and keep in force under this Section 9.5. Notwithstanding the foregoing, Licensor acknowledges and agrees that so long as Company obtains such insurance within [***] ([***])
days after the Effective Date, Company shall not be deemed to be in breach of any of the foregoing. 


 ARTICLE 10

 TERM AND TERMINATION 
  

	10.1	 Term and Expiration. The term of this Agreement (the “Term”) shall commence on the
Effective Date and, unless earlier terminated as provided in this Article 10, shall continue in full force and effect, on a country-by-country and Product-by-Product basis until the date on which the Royalty Term in such country with respect to such Product expires, at which time this Agreement shall expire in its
entirety with respect to such Product in such country and the terms of Section 10.6(b)(i) shall apply. 


  

	10.2	 Termination for Convenience. At any time during the Term, Company may, at its convenience, terminate
this Agreement in its entirety, or on a Product-by-Product or country-by-country basis,
immediately upon [***] ([***]) days’ prior written notice to Licensor. 


  

	10.3	 Termination for Material Breach. 



(a) Material Breach. Either Party may (but is not required to and without limitation of any other right or remedy such Party may
have) terminate this Agreement for material breach by the other Party (the “Breaching Party”) of a material provision of this Agreement if the Breaching 

  
 27 














 CONFIDENTIAL 
  

 
Party has not cured such breach within [***] ([***]) days after receipt of written notice thereof (such period, the “Notice Period”) describing such breach in reasonable detail
and its claim of right to terminate, other than (a) with respect to a material breach of a material payment obligation, in which case the Notice Period shall be [***] ([***]) days, and (b) with respect to such a material breach that cannot
be cured within the Notice Period and the Breaching Party commences actions to cure such breach within the Notice Period, in which case the Notice Period shall be tolled (provided, that the Breaching Party thereafter diligently continues such
actions). For clarity, each Party’s material obligations may apply to the performance of either: (i) this Agreement in its entirety, in which case this provision shall apply to the entire Agreement; or (ii) a specific Product or
Products or country or countries, in which case this provision shall apply only to such affected Product or Products or country or countries. 

(b) Material Breach Dispute. Any dispute regarding an alleged material breach of a material provision of this Agreement or
willful misconduct or fraud in performance of obligations under this Agreement shall be resolved in accordance with Article 11 hereof. Notwithstanding anything to the contrary contained in Section 10.3 or elsewhere in the Agreement, the
applicable cure period for any such alleged material breach or willful misconduct that is in dispute shall be tolled from the date that the alleged breaching Party notifies the other Party that it intends to dispute the allegation through the
resolution of such dispute pursuant to Article 11 and it is understood and acknowledged that, during the pendency of a dispute pursuant to Article 11, all of the terms and conditions of this Agreement shall remain in effect, and the Parties shall
continue to perform all of their respective obligations under this Agreement. 
  

	10.4	 Termination for Patent Challenge. Licensor may terminate this entire Agreement upon written notice to
Company with respect to a Product in the Territory at any time upon providing written notice to the Company, if the Company, or any of the Company’s Affiliates or Sublicensees, directly, or indirectly through assistance provided by a Third
Party, commences any interference or opposition proceeding, challenges the validity or enforceability of, or opposes any extension of or the grant of a supplementary protection certificate with respect to any Licensor Patent (each such action, a
“Patent Challenge”) and Company does not stop such interference or opposition proceeding, challenge or opposition (by Company or any of the Company’s Affiliates or Sublicensees) within [***] ([***]) days
after receipt of written notice thereof and reasonable details related thereto. 


  

	10.5	 Termination for Bankruptcy. Either Party may terminate this Agreement in its entirety upon providing
written notice to the other Party on or after the time that such other Party experiences a Bankruptcy Event. 


  

	10.6	 Effects of Termination. 



(a) Survival. 

(i) Notwithstanding the expiration or termination of this Agreement pursuant to Section 10.2, Section 10.3,
Section 10.4 or Section 10.5, the following provisions shall survive: 1, 2.7 (the second paragraph only), 6.3(e), 7, 8, 9 (other than Section 9.5), 10, 11 and 12. In addition, Section 6.4 and Section 6.5 shall survive any
expiration of the Agreement with respect to a Product in a particular country following the expiration of the Royalty Term with respect to such Product in such country, but only for so long as such Product continues to be Commercialized by or on
behalf of Company or its Affiliates or Sublicensees. 
 (ii) Expiration or termination of this Agreement shall not relieve
the Parties of any 

  
 28 














 CONFIDENTIAL 
  

 
obligation or liability that accrued hereunder prior to the effective date of such expiration or termination. In addition, except for the termination events addressed in Section 10.6(b),
termination of this Agreement shall not preclude either Party from pursuing all rights and remedies it may have hereunder or at Law or in equity with respect to any breach of this Agreement nor prejudice either Party’s right to obtain
performance of any obligation. 
 (iii) All of the following effects of termination are in addition to the other rights and
remedies that may be available to either of the Parties under this Agreement and shall not be construed to limit any such rights or remedies. In the event this Agreement is not terminated in its entirety, but rather is terminated on a Product-by-Product and country-by-country basis with respect to one or more Products (the
“Terminated Product”) in a particular country (the “Terminated Country”), then, notwithstanding anything to the contrary contained in Sections 10.6(a)(i) or 10.6(a)(ii), the consequences of termination described under this
Section 10.6 shall only apply to the Terminated Product in the Terminated Country, and this Agreement shall remain in full force and effect in accordance with its terms with respect to all Products other than the Terminated Products, in all
countries of the Territory other than the Terminated Countries. For clarity, a Terminated Product may be a Compound or Product that was not approved by the Company to be further studied.

(i) As of the effective date of expiration of the Royalty Term with respect to a given Product and country, the licenses from
Licensor to Company under Section 2.1 with respect to such Product and country shall convert to fully paid, royalty-free, irrevocable, and perpetual license. For clarity, all of the Company’s rights under this Agreement which would
naturally continue to apply to Company’s exercise of the foregoing license will remain in effect following any such expiration of a Royalty Term. 

(ii) Upon termination of this Agreement by Company pursuant to Section 10.2 or Section 10.3(a) (due to a breach by
the Licensor) or by Licensor pursuant to Section 10.3(a) (due to a breach by the Company) or Section 10.4, the following terms and conditions shall apply only with respect to such Product(s) and country(ies) as are the subject of such
termination: 
 (1) all licenses granted to Company under Section 2.1 shall automatically terminate (except to the extent reasonably
necessary to provide the transition described herein) and Company shall (except as permitted in Section 10.6(b)(ii)(2)) immediately cease Development and Commercialization of any Product in the Territory; and 

(2) Company and its Affiliates and Sublicensees shall be entitled, during the [***] ([***]) month period following such termination, to sell
any existing commercial inventory of such Product(s) which remains on hand as of the date of the termination, so long as Company makes all Royalty Payments in accordance with the terms and conditions set forth in this Agreement. Any commercial
inventory remaining following the [***] ([***]) month period shall be offered for sale to Licensor at a price [***], as applicable. 

(iii) Upon any termination of this Agreement by Company pursuant to Section 10.3(a) (due to a breach by the Licensor),
each of Company’s Sublicensees shall continue to have the rights and license set forth in its sublicense agreements, which agreements shall be automatically assigned to Licensor; provided, however, that (a) such Sublicensee is not then in
breach of any of its material obligations under its sublicense agreement and (b) Licensor shall have no obligations under such sublicense agreement beyond the obligations expressly set forth in this Agreement.

 (iv) Immediately following Company’s notification of termination to
Licensor pursuant to Section 10.3(a), (unless such termination by Company for Licensor’s breach is the subject of a good faith dispute), the diligence obligations in Section 3.4 shall no longer apply and Company shall have the right
to wind-down all then on-going Development, manufacturing and/or Commercialization activities. 

(v) Upon any termination of this Agreement (with respect to any Product, country or in its entirety) by Company pursuant to
Section 10.2 (subject to the rights of Sublicensees under Section 10.6(b)(iii)) or Section 10.3(a) (due to a breach by the Company), Section 10.4, or Section 10.5 (due to a Company Bankruptcy Event) with respect to each
Terminated Product or Terminated Country, Licensor shall have the right, upon written notice to Company, to discuss with Company for a one-time only period of [***] ([***]) days the possibility of an agreement
whereby Company would license to Licensor certain intellectual property rights, Company would provide to Licensor certain information, Company would assign to Licensor certain agreements, Company would sell certain existing Terminated Product to
Licensor, and Company would transfer or make accessible to Licensor certain Regulatory Documents, in each case, to the extent necessary to enable Licensor to Develop, Commercialize or otherwise exploit such Terminated Product in the Terminated
Country. If Licensor exercises such right and the Parties are unable to reach an agreement within such [***] ([***]) day period, then Company shall be free to discuss and/or enter into an agreement with any Third Party with respect to any such
rights without any further obligation under this Section. In the event that Company determines for the first time that it would like to license its rights with respect to intellectual property and/or other assets related to a Terminated Product
worldwide or with respect to one or more country(ies) to a Third Party, the Company shall so notify Licensor of such determination (the first time only), which notice shall include the rights contemplated to be licensed, including the proposed
country or territory. If Licensor does not request in a written notice to Company a discussion related to an agreement for such rights within [***] ([***]) days after receipt of such notice, then the Company shall be free to discuss and/or enter
into an agreement with any Third Party with respect to any such rights without further obligation under this Section. If Licensor requests in a written notice to Company a discussion related to an agreement for such rights within [***] ([***]) days
after receipt of such notice, but the Parties are unable to reach an agreement within [***] ([***]) days after Licensor submits such request, then the Company shall be free to discuss and/or enter into an agreement with any Third Party with respect
to any such rights without further obligation under this Section. 
  

	10.7	 Effect of Bankruptcy or Insolvency. 



(a) Bankruptcy Code. All rights and licenses granted under or pursuant to this Agreement by Licensor are, and shall otherwise be
deemed to be, for purposes of Section 365(n) of the US Bankruptcy Code, if applicable, licenses of rights to “intellectual property” as defined under Section 101 of the US Bankruptcy Code. 

(b) Continuing Rights. The Parties agree that Company, as licensee of such rights under this Agreement, shall retain and may
fully exercise all of its rights and elections under the US Bankruptcy Code. The Parties further agree that, in the event of any Licensor Bankruptcy Event, Company shall be entitled to a complete duplicate of (or complete access to, as appropriate)
any Exclusive Licensor Know-How and all embodiments thereof, which, if not already in Company’s possession, shall be promptly delivered to it (i) following any such commencement of a bankruptcy
proceeding upon Company’s written request therefor, unless Licensor elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under clause (i), following the rejection of this Agreement by
Licensor upon written request therefor by Company.
