 Subsections (a) through (g) shall be collectively referred to as “Deductions”. The
following principles shall apply in the calculation of Net Sales:

 Notwithstanding the foregoing, in the event a Product is sold in a country in the Territory as a Combination Product, Net Sales of the Combination Product will be calculated as follows: 

 

	 	  	(i) If the Compound contained in the Combination Product and Other Active Ingredient(s) contained in the Combination Product each are sold separately in such country,
Net Sales will be calculated by multiplying the total Net Sales (as described above) of the Combination Product by the fraction A/(A+B), where A is the average gross selling price in such country of the Compound sold separately in the same
formulation and dosage, and B is the sum of the average gross selling prices in such country of such Other Active Ingredient(s) sold separately in the same formulation and dosage, during the applicable Calendar Year. 


 

	 	  	(ii) If the Compound contained in the Combination Product is sold independently of the Other Active Ingredient(s) contained in the Combination Product in such country,
but the average gross selling price of such Other Active Ingredient(s) in such country cannot be determined, Net Sales will be calculated by multiplying the total Net Sales (as described above) of the Combination

Product by the fraction A/C where A is the average gross selling price in such country of such Compound sold independently and C is the average gross selling price in such country of the entire
Combination Product, during the applicable Calendar Year. 

  

	 	  	(iii) If the Other Active Ingredient(s) contained in the Combination Product are sold independently of the Compound contained in the Combination Product in such
country, but the average gross selling price of such Compound in such country cannot be determined, Net Sales will be calculated by multiplying the total Net Sales (as described above) of the Combination Product by the fraction (1-(B/C)), where B is
the average gross selling price in such country of such Other Active Ingredient(s) and C is the average gross selling price in such country of the entire Combination Product, during the applicable Calendar Year. 


 

	 	  	(iv) If the Compound contained in the Combination Product and Other Active Ingredient(s) contained in the Combination Product are not sold separately in such country,
or if they are sold separately but the average gross selling price of neither such Compound nor such Other Active Ingredient(s) can be determined in such country, Net Sales of the Combination Product in such country will be calculated by mutual
agreement of the Parties. 

  

	 	1.39.	“Other Active Ingredient” means any therapeutically active pharmaceutical ingredient other than a Compound. 


 

	 	1.40.	“Patents” means (a) unexpired letters patent (including without limitation inventor’s certificates), including without limitation any
substitution, extension, registration, confirmation, reissue, re-examination, addition, renewal, supplemental protection certificate or inventor’s certificate, and (b) pending applications for letters patent, including without limitation

	 	(c)	except as set forth in clause (a) or (b) above, only with PFIZER’s prior written consent (not to be unreasonably withheld). 


4.1.3. New Clinical Trial. Without limiting the generality of the foregoing, LICENSEE shall itself, or through its Affiliates or

after obtaining Regulatory Approval of Products in such country. LICENSEE will undertake such activities at the sole expense of LICENSEE, its Affiliates or sublicensees, and subject to the foregoing diligence obligations, LICENSEE will have sole
decision making authority with respect to such activities. The Parties acknowledge that under appropriate circumstances it may fall within Commercially Reasonable Efforts in Commercializing Products for LICENSEE to decide not to advance to the next

 4.3.2. PFIZER shall use commercially reasonable efforts to transfer sponsorship of the
Existing Trials (other than the IIRs) and all regulatory reporting requirements relating to the safety of the Product effective as of December 31, 2011. After sponsorship for all such trials has been transferred to LICENSEE pursuant to the
Transition Plan, LICENSEE shall have all regulatory and pharmacovigilance responsibilities for the Compounds and Products as of such transfer date. During the period after the Closing Date and prior to such transfer date, the Parties shall keep each
other informed as to the status of this transfer via the Transition Committee and shall discuss whether or not it may be necessary to put in place a written agreement for exchanging adverse event and other safety information relating to the Products
prior to PFIZER’s or its Affiliate’s transfer of any existing IND to LICENSEE. If they agree that such an agreement is necessary, they shall promptly meet and agree upon such an agreement (the “Pharmacovigilance

will use reasonable efforts upon reasonable notice to order the quantities of Product requested by LICENSEE in writing, at LICENSEE’s cost; provided further that via the Transition Committee, the Parties will discuss necessary lead times and
how to handle release testing and any other activities related to any such request. LICENSEE agrees that it shall comply with the applicable requirements of 35 U.S.C. § 204 to the extent required in connection with manufacturing Products;
provided, however, that PFIZER will, upon LICENSEE’s request and at LICENSEE’s expense, request pursuant to the GHC License Agreement that MGH assist LICENSEE in obtaining a waiver of the foregoing requirement, in the event such a waiver
should be required.

Section 6.2 of the Transition Plan) transferred to LICENSEE pursuant to the Transition Plan, to the extent that either (a) LICENSEE uses any such Pfizer Neratinib Inventory or Comparator Inventory [***] and LICENSEE subsequently [***] for
use in conducting the Existing Trials under Section 3.6 or (b) LICENSEE [***] and instead LICENSEE [***], then [***]. 

4.4.3. To the extent any comparator drugs are required for the Trial Completion Activities beyond the Comparator Inventory transferred to
LICENSEE pursuant to the Transition Plan, LICENSEE shall be responsible for acquiring such

quantities of comparator drugs for use in the Existing Advanced Trials requested by LICENSEE in writing, at LICENSEE’s expense [***]; provided further that via the Transition Committee, the Parties will discuss necessary lead times and any
other activities related to any such request.

matters before the committee (subject to LICENSEE’ s commitments and obligations under the Agreement). The Governance Committee will meet at least once per year or more frequently as agreed-upon by the Parties. Upon the request of a
Party’s representative on the Governance Committee, subject to the other Party’s prior consent (not to be unreasonably withheld or delayed), other personnel from such Party may attend and participate in such meetings.

	 	(c)	In the event that LICENSEE [***] (the “Third Party Patents”), and if LICENSEE pays [***] under license agreements with such Third Parties [***] (the
“Third Party Payments”), then LICENSEE may credit [***] of such Third Party Payments against the Royalties owed and payable on the Net Sales for such Product, as determined on a country-by-country basis. Notwithstanding the foregoing, in

5.1.3. Assumption of Responsibility. The Parties acknowledge that LICENSEE’s assumption of all responsibility, at its sole
cost (except as set forth in Section 3), for the Existing Trials with effect from the Closing Date in accordance with Section 3, including LICENSEE’s Trial Completion Activities, shall serve as further consideration for the licenses

the last day of each month of the Calendar Quarter in which such Net Sales occurred, and the amounts due for Royalties hereunder will be expressed in U.S. dollars. For purposes of calculating the Net Sales thresholds set forth in [***], the
aggregate Net Sales with respect to each Calendar Quarter within a Calendar Year will be calculated based on the currency exchange rates for the Calendar Quarter in which such Net Sales occurred, in a manner consistent with the exchange rate
procedures set forth in the immediately preceding sentence.

“Taxes”), [***]. 
 5.3.2. Withholding Taxes. If LICENSEE is required to make a payment to PFIZER subject
to a deduction of tax or withholding tax, the sum payable by LICENSEE (in respect of which such deduction or withholding is required to be made) shall be made to PFIZER after deduction of the amount required to be so deducted or withheld, which
deducted or withheld amount shall be remitted in accordance with applicable law, provided, however, that if such withholding or deduction obligation arises solely as a result of [***], then the sum payable by LICENSEE (in respect of which
such deduction or withholding is required to be made) shall be [***]. Any amounts deducted, withheld and remitted in accordance with the provisions of this Section 5.3.2 shall be treated as having been paid by the LICENSEE to PFIZER for all
purposes of this Agreement.

any payments to PFIZER, LICENSEE shall pay the amounts of such taxes to the proper governmental authority in a timely manner and, upon PFIZER’s request, shall promptly transmit to PFIZER an official tax certificate or other evidence of such
withholding sufficient to enable PFIZER to claim such payments of taxes. PFIZER shall provide to LICENSEE any tax forms that may be reasonably necessary in order for LICENSEE not to withhold tax or to withhold tax at a reduced rate under an
applicable bilateral income tax treaty. Each party shall provide the other with reasonable assistance to enable the recovery, as permitted by law, of withholding taxes, VAT, or similar obligations resulting from payments made under this Agreement,

first right, but not the obligation, to prepare, file, prosecute and maintain any Joint Patent Right that is not a Patent Right, in each case throughout the world, using patent counsel that is reasonably acceptable to PFIZER. If LICENSEE declines to
exercise its first right, PFIZER shall have the right (but not the obligation) to prepare, file, prosecute and maintain such Joint Patent Right, in each case throughout the world. The Party that at the time exercises the right to prepare, file,
prosecute and maintain such a Joint Patent Right may be referenced as the “Controlling Party” below with respect thereto, and the other Party may be referenced as the “Other Party” below with respect thereto. The Controlling
Party shall give the Other Party an opportunity to review the text of any patent application with respect to such Joint Patent Right at least [***] before filing and shall consider the Other Party’s

comments in good faith. The Controlling Party shall supply the Other Party with a copy of the patent application as filed, together with notice of its filing date and serial number. To the extent
it is Controlling Party for such Joint Patent Rights, LICENSEE shall follow the patent prosecution practice described in Sections 7.4.1 and 7.4.2. The Other Party shall reimburse the Controlling Party for fifty percent (50%) of the costs
incurred by the Controlling Party in preparing, filing, prosecuting and maintaining any such Joint Patent Right, which reimbursement will be made pursuant to invoices submitted by the Controlling Party to the Other Party no more often than once per
Calendar Quarter; provided that, for clarity, LICENSEE shall be responsible for all such costs for any Joint Patent Right that is also a Patent Right. If either Party (the “Declining Party”) at any time declines to share in the costs of
filing, prosecuting and maintaining any such Joint Patent Right, on a country by country basis, the Declining Party shall provide the other Party (the “Continuing Party”) with [***] prior written notice to such effect, in which event,
(i) the Declining Party shall have no responsibility for any expenses incurred in connection with such Joint Patent Right after the end of such [***] period, (ii) if the Continuing Party elects to continue prosecution or maintenance, the
Declining Party, upon the Continuing Party’s request, shall execute such documents and perform such acts, at the Continuing Party’s expense, as may be reasonably necessary to assign to the Continuing Party all of the Declining Party’s
right, title and interest in and to such Joint Patent Right, with such Joint Patent Right automatically ceasing to be a Joint Patent Right and becoming the patent right solely of the Continuing Party as of the date of such written notice from the
Declining Party, and (iii) for clarity, if the Declining Party is LICENSEE and such Joint Patent Right would otherwise thereafter be a Patent Right or Future Patent Right, then [***].

	 	8.1.	Notice. Each Party will promptly notify the other Party in writing of (a) any actual or threatened infringement, misappropriation, other violation,
or challenge to the validity, scope or enforceability by a Third Party of any Licensed Technology in the Territory of which it becomes aware (“Third Party Infringement”) and (b) any allegation by a Third Party that any
Intellectual Property Right owned by it is infringed, misappropriated, or otherwise violated by the Development, Commercialization, and/or Use of any Product of which it becomes aware (“Defense Action”). 


 

	 	8.2.	Licensee Control. LICENSEE shall have the first right (but not the obligation), at its own expense, to control enforcement of the Licensed Technology
against any Third Party Infringement. Prior to commencing involvement in any such suit, action or proceeding, LICENSEE shall consult with PFIZER and shall consider PFIZER’s timely recommendations regarding the proposed suit, action or

proceeding, except to the extent delay may reasonably result in the loss of rights by or otherwise adversely impact LICENSEE or PFIZER. LICENSEE shall give PFIZER timely notice of any proposed
settlement of any such suit, action or proceeding that LICENSEE controls and LICENSEE shall not settle, stipulate to any facts or make any admission with respect to any Third Party Infringement without PFIZER’s prior written consent (not to be
unreasonably withheld) if such settlement, stipulation or admission would: (a) adversely affect the validity, enforceability or scope, or admit non-infringement, of any of the Licensed Technology; (b) give rise to liability of PFIZER or
its Affiliates; (c) grant to a Third Party a license or covenant not to sue under, or with respect to, any Intellectual Property Rights Controlled by PFIZER or its Affiliates (other than as expressly provided for in this Agreement with respect
to LICENSEE’s rights to sublicense the Licensed Technology); or (d) otherwise impair PFIZER’s or any of its Affiliates’ rights in any Licensed Technology or PFIZER’s or any of its Affiliates’ rights in this Agreement.


  

	 	8.3.	Pfizer Control. PFIZER shall have the right (but not the obligation) to control enforcement of the Licensed Technology against any Third Party
Infringement if LICENSEE provides PFIZER with written notice that it is not exercising its right to control such enforcement, or if LICENSEE fails to initiate or file the relevant response to (as applicable), a suit, action or proceeding with
respect to such Third Party Infringement prior to or upon the earlier of: (a) expiration of the [***] period following first receipt by either Party of notice from the other Party of such Third Party Infringement or (b) [***] prior to the
deadline for filing, or filing the applicable response to (as applicable), such suit, action or proceeding (including suits, actions or proceedings based on a Third Party’s filing of a Paragraph IV Certification under 21 CFR
§314.94(a)(12)(i)(A)(4))). 

  

	 	8.4.	Rights of Non-Controlling Party. Notwithstanding anything to the contrary herein, the Party that is not controlling the suit, action or proceeding
pertaining to enforcement of the Licensed Technology against Third Party Infringement as described in this Section 8 shall join as a party to such suit, action or proceeding upon the reasonable request and expense of the Party controlling such
action if necessary for standing purposes. The Party that is not controlling such a suit, action or proceeding shall have the right to be represented by counsel (which shall act in an advisory capacity only, except for matters solely directed to
such Party) of its own choice and at its own expense (subject to Section 8.5) in any such suit, action or proceeding. 

  

	 	8.5.	Recoveries. Any and all recoveries resulting from a suit, action or proceeding relating to a claim of Third Party Infringement shall first be applied to
reimburse each Party’s costs and expenses in connection with such suit, action or proceeding, with any remaining recoveries (the “Remaining Recoveries”) allocated (i) if the controlling Party is LICENSEE, [***], with [***], and
(ii) if the controlling Party is PFIZER [***].

LICENSEE, at LICENSEE’s expense, to the extent necessary to defend LICENSEE or any Affiliate or sublicensee of LICENSEE in a Defense Action in which the claim of infringement,
misappropriation or other violation is directed at LICENSEE’s or its sublicensee’s Use of a Compound (as such Compound exists as of the Execution Date) or the Know-How (in accordance with Section 2). LICENSEE shall have all authority
with respect to any Defense Action, including the right to exclusive control of the defense of any such suit, action or proceeding and the exclusive right to compromise, litigate, settle or otherwise dispose of any such suit, action, or proceeding;
provided that LICENSEE shall keep PFIZER timely informed of the proceedings and filings, and provide PFIZER with copies of all communications pertaining to each Defense Action and LICENSEE shall not settle, stipulate to any facts or make any
admission with respect to any Defense Action without PFIZER’s prior written consent if such settlement, stipulation or admission would: (a) adversely affect the validity, enforceability or scope, or admit non-infringement, of any of the
Licensed Technology; (b) give rise to liability of PFIZER or its Affiliates; (c) grant to a Third Party a license or covenant not to sue under, or with respect to, any Intellectual Property Rights Controlled by PFIZER or its Affiliates,
other than as expressly provided for in this Agreement with respect to LICENSEE’s rights to sublicense the Licensed Technology; or (d) otherwise impair PFIZER’s or any of its Affiliates’ rights in any Licensed Technology or

Regulatory Authorities during the term of this Agreement any applicable Patent Rights for a Compound or Product that has become the subject of an application for Regulatory Approval submitted to FDA. Such listings may include without limitation all
so-called “Orange Book” listings required under the Hatch-Waxman Act and all so-called “Patent Register” listings as required in Canada. PFIZER will reasonably cooperate, at LICENSEE’s request and expense, in preparing
and/or filing such listings within the time frames available or required for such listings to be submitted in connection with such Compound and/or Product. LICENSEE may request in writing that [***], in order for it to be listed with the applicable
Regulatory Authorities under this paragraph. In such case, PFIZER shall not unreasonably withhold its consent to such [***]; provided that if PFIZER reasonably believes it might want to list such [***] with the Regulatory Authorities for products
other than Products, then it may withhold its consent without further explanation. 

  

	 	8.8.	Patent Term Extension. LICENSEE shall notify PFIZER of the date of Regulatory Approval of a Product by the relevant Regulatory Authority. LICENSEE shall have the
right to prepare and file, or to cause PFIZER to prepare and file (at LICENSEE’s request and expense), a patent term extension or supplementary protection certificate application upon Regulatory Approval of such Product. At LICENSEE’s
request and expense, PFIZER shall provide to

	 	9.1.	Definition. “Confidential Information” means the terms and provisions of this Agreement and other proprietary information and data of a
financial, commercial or technical nature (including such information or data of or relating to a Third Party) that the disclosing Party or any of its Affiliates has supplied or otherwise made available to the other Party or its Affiliates, which
are disclosed, whether orally, visually or in writing. All Know-How shall be considered PFIZER’s Confidential Information.

Each receiving Party will treat Confidential Information provided by the other Party with the same degree of care as if it were the receiving Party’s own confidential information (but under no circumstances less than reasonable care). The
receiving Party may disclose the Confidential Information of the disclosing Party to its Affiliates, and their respective directors, officers, employees, subcontractors, sublicensees, consultants, attorneys, accountants, banks, acquirers and

	 	(c)	is disclosed to the receiving Party on a non-confidential basis by a Third Party who is entitled to disclose it without breaching any confidentiality obligation to the
disclosing Party; or 

  

	 	(d)	is independently developed by or on behalf of the receiving Party or any of its Affiliates, as evidenced by its written records, without use or access to the
Confidential Information. 

 9.3.2. The restrictions set forth in this Section 9 shall not prohibit the

8, or (iii) that LICENSEE, as receiving Party, needs to disclose or use for purposes of obtaining or maintaining Regulatory Approval of Products; provided that the receiving Party (a) as to subsection (i), provides the disclosing Party at
least [***] prior written notice of such disclosure (and the right to review and comment on the proposed disclosure), to the extent practicable, (b) as to subsection (i), affords the disclosing Party an opportunity to oppose or limit, or secure
confidential treatment for such required disclosure or, for submissions or disclosures required by the SEC or national securities exchange, itself uses reasonable efforts to secure confidential treatment for such required disclosure, (c) as to
subsection (i) discloses only that portion of the Confidential Information that the receiving Party is legally required to disclose as advised by the receiving Party’s legal counsel and (d) as to subsections (ii) and (iii), the
receiving Party provides reasonable advance notice to the other Party where reasonably practicable and discloses only that portion of the Confidential Information that it is reasonably necessary to disclose for such purpose. 

9.3.3. In the event that PFIZER wishes to assign, pledge or otherwise transfer its rights to receive some or all of the Milestone Payments

of confidentiality with terms and conditions at least as restrictive as those set forth in this Agreement. To the extent that any such assignment would affect LICENSEE’s performance of its obligations hereunder, PFIZER shall notify LICENSEE
promptly if it enters into any agreement under which it has assigned its rights to receive some or all of the Milestone Payments and Royalties payable hereunder. 
  

	 	9.4.	Right to Injunctive Relief. Each Party agrees that breaches of this Section 9 may cause irreparable harm to the disclosing Party and may entitle the
disclosing Party, in addition to any other remedies available to it (subject to the terms of this Agreement), the right to seek injunctive relief enjoining such action.

	 	9.6.	Specific Procedures in Regard to Financing. Any disclosure made by LICENSEE to prospective investors or others in connection with the financing LICENSEE expects
to complete in order to satisfy the Financing Condition shall be made only pursuant to Confidentiality and Non-Disclosure Agreements or other arrangements in form and substance satisfactory to PFIZER.

“Indemnifying Party”) pursuant to this Agreement, the Indemnified Party shall: (a) give the Indemnifying Party prompt written notice of the Claim; provided, however, that failure to provide such notice shall not relieve the

confirms in writing that it is liable to indemnify the PFIZER Indemnitees or the LICENSEE Indemnitees, as applicable, in connection with the relevant matter and provides reasonable substantiation
that the Indemnifying Party has the financial resources to pay for the defense and settlement of the Claim (including any settlement thereof or judgment thereon); provided, however, that the Indemnifying Party may not settle the Claim without the

its sole discretion, at any time on or after the date that is eighteen (18) months after the Closing Date on not less than one hundred eighty (180) days prior written notice to PFIZER. 


 

	 	  	13.2.2. Termination for Safety Concerns. LICENSEE may terminate this Agreement in its entirety on not less than sixty (60) days prior written notice to PFIZER if

	 	  	13.2.3. Termination Generally. This Agreement may not be terminated by LICENSEE under this Section 13.2 on a Compound-by-Compound, or country-by-country or other
partial basis. 

  

	 	13.3.	Termination for Cause. Each Party shall have the right, without prejudice to any other remedies available to it at law or in equity, to terminate this Agreement
in the event the other Party breaches any of its material obligations hereunder and fails to cure such breach within thirty (30) days of receiving notice thereof; provided, however, if such breach is capable of being cured, but
cannot be cured within such thirty (30) day period, and the breaching Party initiates actions to cure such breach within such period and thereafter diligently pursues such actions, the breaching Party shall have such additional period as is
reasonable to cure such breach, but in no event will such additional period exceed sixty (60) days unless otherwise agreed in writing by the Parties. Any termination by a Party under this Section 13.3 shall be without prejudice to any
damages or other legal or equitable remedies to which it may be entitled from the other Party. For the avoidance of doubt, LICENSEE’s failure to use Commercially Reasonable Efforts to Develop and Commercialize Products in each Major Market
Country shall constitute a breach of a material obligation by LICENSEE under this Agreement.

“Bankruptcy Event” means the occurrence of any of the following: (a) the institution of any bankruptcy, receivership, insolvency, reorganization or other similar proceedings by or against LICENSEE under any bankruptcy,
insolvency, or other similar law now or hereinafter in effect, including any section or chapter of the United States Bankruptcy Code, as amended or under any similar laws or statutes of the United States or any state thereof (the “Bankruptcy
Code”), where in the case of involuntary proceedings such proceedings have not been dismissed or discharged within ninety (90) days after they are instituted, (b) the insolvency or making of an assignment for the benefit of

desired economic effect and mutual understanding of the Parties under this Agreement. 

  

	 	17.3.	Governing Law; Exclusive Jurisdiction.

irrevocably: (a) submits to such exclusive jurisdiction for such purpose; (b) waives any objection which it may have at any time to the laying of venue of any proceedings brought in such courts; (c) waives any claim that such
proceedings have been brought in an inconvenient forum, and (d) further waives the right to object with respect to such proceedings that any such court does not have jurisdiction over such Party. Notwithstanding the foregoing, application may
be made to any court of competent jurisdiction with respect to the enforcement of any judgment or award, or the pursuit of injunctive or other equitable relief described in Section 16.1. 


 

	 	17.4.	Force Majeure. Except with respect to delays or nonperformance caused by the negligent or intentional act or omission of a Party, any delay or
nonperformance by such Party (other than payment obligations under this Agreement) will not be considered a breach of this Agreement to the extent such delay or nonperformance is caused by acts of God, natural disasters, acts of the government or
civil or military authority, fire, floods, epidemics, quarantine, energy crises, war or riots or other similar cause outside of the reasonable control of such Party (each, a

	 	17.5.	Waivers and Amendments. The failure of any Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not
constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party. No waiver shall be effective unless it has been given in writing and signed by the Party giving such waiver. No
provision of this Agreement may be amended or modified other than by a written document signed by authorized representatives of each Party.
