 1.6 “Joint Clinical Development” means the Clinical Studies and related
activities performed under this Agreement. 
 1.7 “Phase 1 Clinical Study” means the first phase of a clinical study
involving the initial introduction of an investigational new drug into humans (generally, but not always, in the range of 20 to 30 subjects). Phase 1 studies are typically closely monitored and may be conducted in patients or normal volunteer
subjects. These studies are designed to determine the metabolism and pharmacologic actions of the drug in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on effectiveness that provides data capable
of meeting statutory standards for marketing approval. During Phase 1, sufficient information about the drug’s pharmacokinetics and pharmacological effects should be obtained to permit the design of well-controlled, scientifically valid, Phase
2 studies. For example, “Phase 1 Clinical Study” includes a human clinical study that satisfies the requirements of 21 C.F.R. § 312.21(a) in the United States, or an equivalent or counterpart of the foregoing in any other country
or jurisdiction. 
 1.8 “Phase 2 Clinical Study” means the second phase of a clinical study, the principal purpose of which
is to evaluate the effectiveness of the drug for a particular indication and to determine the common short term side effects and risks associated with the drug in patients with the disease target being studied, that provides data capable of meeting
statutory standards for marketing approval. Phase 2 studies usually involve no more than several hundred subjects. For example, “Phase 2 Clinical Study” includes a human clinical study that satisfies the requirements of 21 C.F.R.
§ 312.21(2) in the United States, or an equivalent or counterpart of the foregoing in any other country or jurisdiction. 
 1.9
“Sponsored Research Agreement” means that certain agreement for such name entered by MSKCC and Sponsor of even date herewith.

 22 








 
MSKCC for the conduct of the Clinical Studies), and (ii) an exclusive option to acquire from MSKCC an exclusive, worldwide, royalty-free license, with the right to grant sublicenses through
multiple tiers, under MSKCC’s interest in any and all Study Intellectual Property that is/are an improvement to any intellectual property licensed by Sponsor to MSKCC for the conduct of one or more Clinical Studies) (“Option”);
provided, however reserving to MSKCC, in each case, a paid-up, non-exclusive, irrevocable license to use and, with the prior written consent of Sponsor, in its sole discretion, to sublicense to other not-for-profit research organizations to use, any
patent applications and patents within such Study Intellectual Property for noncommercial research purposes, patient care, and teaching. Unless it is terminated sooner under this Agreement, the Option will terminate automatically unless it is
exercised within [***]. 
 (b) Sponsor may exercise the Option by giving MSKCC written notice of exercise of the Option describing the Study
Intellectual Property that it wishes to license. In such case, the parties shall negotiate in good faith with respect to a license agreement for such intellectual property, with the terms of such license being commercially reasonable and competitive
as of the date such license is entered into. In the event the parties are unable to agree on such terms within [***] days, MSKCC and Sponsor shall appoint a neutral, independent expert with extensive expertise in the licensing of pharmaceutical
technology and products to act as an expert (not as an arbitrator) (the “Expert”), at the expense of each of each of MSKCC and Sponsor in equal proportions, to make its independent determination of the commercially reasonable
economic terms for such a license to the applicable intellectual property (the “Expert’s Determination”). In any such determination the Expert shall take into account, inter alia, (i) any joint ownership interest
that Sponsor may have in such intellectual property, and (ii) the ability (or inability, as the case may be) for such intellectual property to be practiced without a license to any other intellectual property that is licensed to Sponsor by
MSKCC. If MSKCC and Sponsor are unable to agree on an expert within [***] days, each of the MSKCC and Sponsor will each designate a neutral, independent individual with the qualifications above, and those individuals will select a third neutral
independent individual with the qualifications above to act as the Expert. Each of the parties shall provide the Expert with a written proposal detailing their respective proposed terms, and make available to such Expert on a confidential basis such
books, accounts, records and forecasts as the Expert may reasonably request, including terms of other licenses entered into by each of the parties that may be useful in determining the commercially reasonable terms of licensing. The Expert shall
select the proposal of one of the parties as his or her Expert’s Determination, without varying any of the terms thereof. The Expert’s Determination shall be final and binding on the parties, and shall constitute the key terms of the
license. 
 (c) If the Exclusive License Agreement is in effect between the parties, any Study Intellectual Property that is licensed by
Sponsor pursuant to its exercise of the Option shall be included in the licensed Patent Rights and/or MSKCC Know How, as the case may be (as such terms are defined in the License Agreement), and the rights and obligations (including royalty
obligations) between the parties regarding such Study Intellectual Property shall be governed by the License Agreement with no additional payments due under this Agreement.

 12.5 Termination of Certain Rights of Sponsor. If Sponsor does not request that MSKCC file
a patent application for any Study Intellectual Property within the [***] day period provided for in Section 12.4, or as otherwise provided in Section 12.3(b), or does not provide financial support with respect to the preparation, filing,
prosecution or maintenance of any patent or patent application as required by this Agreement, the Option will expire with respect to that patent application or patent and MSKCC, at its sole expense, may prepare and file or continue prosecution or
maintenance of that patent or patent application. 
 12.6 Pre-existing Rights. No party claims by virtue of this Agreement any right,
title, or interest in or to any issued patents or pending patent applications owned or controlled by any other party as of the date of this Agreement. Nothing in this Agreement will be construed as granting any license or obligation to license any
intellectual property to the other party other than as expressly set forth herein, including (a) the Option granted under Section 12.4, (b) the limited right to use Study Product and to manufacture and use Study Product in accordance
with the terms of this Agreement and the applicable Study Agreement. 
 12.7 Research License. Sponsor hereby grants to MSKCC a
non-exclusive, non-transferable, royalty-free, non-sublicensable (except with the further prior written consent of Sponsor, including as set forth in a Study Agreement) license to intellectual property owned or controlled by Sponsor solely to the
extent necessary to allow MSKCC to perform its obligations under the Study Agreement(s). 
 12.8 CREATE. The parties intend for the
Joint Clinical Development to qualify for the benefits of the Cooperative Research and Technology Enhancement Act (35 U.S.C. § 103) (the “CREATE Act”). Accordingly, each party agrees to use reasonable efforts to do, and
cause its employees to do, all lawful acts that may be or become necessary to evidence, maintain, record and perfect rights of the parties provided by the CREATE Act. 

12.9 Common Interest Disclosures. With regard to any information or opinions disclosed pursuant to this Agreement by one party to each
other regarding intellectual property and/or technology owned by third parties, Sponsor and MSKCC agree that they have a common legal interest in determining whether, and to what extent, third party intellectual property rights may affect the
conduct of the Joint Clinical Development, and have a further common legal interest in defending against any actual or prospective third party claims based on allegations of misuse or infringement of intellectual property rights relating to the
conduct of the Joint Clinical Development. Accordingly, Sponsor and MSKCC agree that all such information and materials obtained by Sponsor and MSKCC from each other will be used solely for purposes of the Parties’ common legal interests with
respect to the conduct of the Agreement. All information and materials will be treated as protected by the attorney-client privilege, the work product privilege, and any other privilege or immunity that may otherwise be applicable, except with
respect to disputes arising between the parties. By sharing any such information and materials, neither party intends to waive or limit any privilege or immunity that may apply to the shared information and materials. Neither party shall have the
authority to waive any privilege or immunity on behalf of the other party without such other party’s prior written consent, nor shall the waiver of privilege or immunity resulting from the conduct of one party be deemed to apply against any
other party.

	13.	INDEMNITY, INSURANCE AND RESEARCH RELATED INJURY 

 13.1 Indemnification by
Sponsor. Sponsor will indemnify, defend, and hold harmless MSKCC, and its trustees, officers, professional staff, employees, agents, successors, heirs and assigns (“MSKCC Indemnitees”) from and against: 

(a) All third party claims, debts, liabilities and obligations which arise from or are alleged to arise from i) [***]; or ii) [***]; 

(b) Any damage or deficiency resulting directly or indirectly [***]; and 

(c) All third party other actions, suits, proceedings, demands, assessments, adjustments, costs and expenses incident to the foregoing,
including actual attorneys’ fees and other out-of-pocket expenses. 
 This indemnification will not apply to the extent that the claims, debts,
liabilities, obligations, damages, deficiencies or expenses (collectively “Claims”) for which indemnification is sought under this Agreement are caused by the [***] of the MSKCC Indemnitees or are [***]. 

13.2 Indemnification by MSKCC. MSKCC will indemnify, defend, and hold harmless Sponsor and its directors, officers, professional staff,
employees, agents, successors, heirs and assigns (“Sponsor Indemnitees”) from and against: 
 (a) All third party claims,
debts, liabilities and obligations which arise from or are alleged to arise from the [***]; 
 (b) Any damage or deficiency resulting
directly or indirectly from [***]; and 
 (c) All third party other actions, suits, proceedings, demands, assessments, adjustments, costs and
expenses incident to the foregoing, including actual attorneys’ fees and other out-of-pocket expenses. 
 This indemnification will not apply to the
extent that the Claims for which indemnification is sought under this Agreement are caused by the [***]. 
 13.3 Indemnification
Procedures. The Indemnitees will give the party from whom indemnification is sought under this Agreement (in this capacity “Indemnitor”) reasonable notice of any Claims asserted against such Indemnitees. Failure to give such
notice will not abrogate or diminish Indemnitor’s indemnity obligation if Indemnitor [***] or if such failure does not prejudice Indemnitor’s ability to defend the Claim. In any litigation, administrative proceeding, negotiation or
arbitration pertaining to any 
  
 [***] Certain information in this document has
been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 

  
 25 








 
Claim for which indemnification is sought under this Agreement, Indemnitor will select competent legal counsel acceptable to the Indemnitees in their reasonable discretion to represent the
Indemnitees. Indemnitor will control such litigation, proceedings, negotiations and arbitration. The Indemnitees will at all times have the right to fully participate in the defense at their own expense. If Indemnitor, within a reasonable time after
notice, fails to defend, the Indemnitees will have the right, but not the obligation, to undertake the defense of and to compromise or settle the Claim or other matter on behalf, for the account, and at the risk of Indemnitor. If the Claim is one
that cannot by its nature be defended solely by Indemnitor, then the Indemnitees will make available all information and assistance Indemnitor may reasonably request at Indemnitor’s expense. 

13.4 Insurance. Each party represents, warrants and agrees that it will maintain during the term of this Agreement and for a period of
[***] thereafter, a liability insurance policy at levels and with coverage (including product liability and professional liability coverage) sufficient to support the indemnification obligations and other obligations assumed under this Agreement and
all Study Agreements but in no event less than [***]. Each party will provide the other party with written evidence of the insurance upon request and will give notice to the other party at least [***] days prior to cancellation, nonrenewal or
material change in the insurance coverage. If a party does not obtain replacement insurance providing comparable coverage within [***] days, the other party will have the right to terminate its participation under this Agreement immediately. 

13.5 Participant Injury Attributable to the Clinical Trial. Sponsor agrees to pay, [***] participating in clinical trials related to a
Clinical Study for illness or injury attributable to a Study Product except [***]. For purposes of this determination, “attributable” means that the receipt of the Study Product and the research subject’s illness or injury are
reasonably related in time, and the illness or injury is more likely explained by the receipt of the Study Product than another cause. 
  

	14.	TERM AND TERMINATION 

 14.1 Term. The initial term of this Agreement will begin on
the Effective Date and continue for five (5) years unless sooner terminated as permitted in this Agreement. The term of this Agreement may be extended or renewed only by mutual written agreement signed by a duly authorized representative of
each party. 
 14.2 Termination for Cause. 

(a) Subject to subsection 14.2(b), if a party materially breaches the terms of this Agreement or a Study Agreement, then the other party may
terminate the agreement to which the breach relates at its option and without prejudice to any of its other legal and equitable rights and remedies, by giving the party who committed the breach thirty (30) days’ notice in writing,
specifying the breach. The agreement with respect to which notice is given will be deemed terminated upon expiration of the thirty (30) day period unless the breach is cured prior to such expiration; provided, that if the breach is such
that more than thirty (30) days is reasonably required for its cure, then the party who committed the breach will not be deemed to be in breach if it commences the cure within the thirty (30) day period and diligently pursues the cure to
completion. 

  
 26 








 (b) Notwithstanding subsection (a), if the agreement that is being terminated for breach is this
Agreement, the party that wishes to terminate this Agreement must [***] before giving the thirty (30) day written notice of breach described in subsection (a). If the matter cannot be resolved after [***], the party wishing to terminate may
continue to pursue termination under this Section 14.2. 
 14.3 Termination on Insolvency and Related Events. This Agreement will
terminate on written notice from either party if the other party becomes insolvent, makes any assignment for the benefit of creditors, if a petition in bankruptcy if filed by or against the other party, or if a receiver or trustee of the other
party’s property is appointed. 
 14.4 Effect of Termination. 

(a) Unless otherwise agreed by the parties, all Clinical Studies and related Study Agreements will terminate effective upon termination of this
Agreement. 
 (b) Termination of this Agreement or a Study Agreement by any party for any reason will not affect any rights and obligations
of the parties which accrue prior to the effective date of termination. 
 (c) Upon termination of this Agreement or a Study Agreement, a
party entitled to reimbursement under the Agreement being terminated will be reimbursed for all costs and non-cancelable commitments reasonably incurred by it in the performance of any terminated Clinical Study. In addition, in the event that this
Agreement is terminated prior to completion of a Clinical Study, the amount due to MSKCC from Sponsor shall be as agreed by the parties for each patient who was enrolled in the Clinical Study any time between the commencement of such Clinical Study
and the date of termination of this Agreement. For purposes of this Agreement “enrollment” shall mean a patient that has signed the Patient Consent Form and successfully passed any pretreatment screening that is required. 

(d) If a Study Agreement is terminated prior to completion of the Clinical Study to which it relates for any reason the parties will cease
enrolling research subjects in any clinical trial that is part of that Clinical Study, stop using the Study Product for that Clinical Study and stop conducting any procedures on research subjects enrolled in a clinical trial that is part of that
Clinical Study as soon as practicable, with due regard for the safety and welfare of research subjects. 
 (e) If Sponsor terminates the
Agreement prior to completion of a Clinical Study, Sponsor shall, if feasible, permitted by law and requested in writing by MSKCC, allow MSKCC to complete the treatment of those patients participating in the Clinical Study on the date of
MSKCC’s receipt of Sponsor’s termination notice. 
  
 [***] Certain
information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 

  
 27 








 (f) Upon a termination of this Agreement by MSKCC for breach by Sponsor, the parties acknowledge
and agree that Sponsor Funding not yet funded by Sponsor may be included among damages for breach for which MSKCC may recover. For the avoidance of doubt, termination of this Agreement shall have no effect on the Contingent License Agreement or any
other agreement entered by the parties hereto. 
 (g) Any Sponsor Funding paid to MSKCC pursuant to Study Agreements that have been not been
expended on, or irrevocably committed to be paid to third parties under, Clinical Studies as of the termination of the Agreement shall be repaid to Sponsor by MSKCC within [***] days of any such termination, unless otherwise agreed by the parties.

 (h) Unless the parties expressly agree otherwise, the rights and obligations under this Agreement or any Study Agreement that would, by
their nature, survive expiration or termination or that have accrued prior to expiration or termination, including the representations, warranties and indemnifications in this Agreement or in any Study Agreement, will survive expiration or
termination of this Agreement. For the avoidance of doubt, the provisions of Sections 3.7, 3.8, 3.9, 3.11, 3.12, 3.13, 3.15, 5.3, 5.4 and 7.3 and Articles 8, 9, 10, 11, 12, 13, 14 and 15 shall survive the termination of this Agreement for any
reason.

Affiliate, or (b) Sponsor may assign this Agreement in connection with the transfer of all or substantially all of Sponsor’s assets, whether via a merger, sale, reorganization or other transaction, provided, in each case, that such party
is in good standing under this Agreement at such time, and that the entity to which the Agreement is assigned agrees in writing to fulfill all of such party’s obligations under this Agreement and any ongoing Study Agreements. Except as
expressly provided above, any attempted assignment or transfer without the consent of the other party will be void. This Agreement will inure to the benefit of and be binding upon the parties and their respective successors and permitted assigns.

 15.6 Severability. If any provision of this Agreement is held to be invalid, illegal or unenforceable by a court or regulatory body
of competent jurisdiction, such provision will be enforced to the maximum extent permitted by law and in compliance with the parties’ intent, and the remaining provisions will not be affected or impaired.
