In addition, no Party may refer such unresolved matter as a dispute for resolution in accordance with Section 13.2 (Dispute Resolution).

3.9.Scope of Governance. Notwithstanding the responsibilities delegated to the Committees, each Party shall retain the rights, powers and discretion granted to it under this Agreement, and the Committees shall not be delegated or vested with rights, powers or discretion unless such delegation or vesting is expressly provided in this Agreement, or the Parties expressly so agree in writing. The Committees shall not have the power to amend or modify this Agreement, and no decision of the Committees shall be in contravention of any terms and conditions of this Agreement.

In the event Pfizer elects to so Commercialize zavegepant in the Field in the Territory, the Parties shall (a) update the Development Plan to include a clinical plan to Develop zavegepant for Regulatory Approval in the Territory, (b) update the Commercialization Plan to include a plan to Commercialize zavegepant in the Territory, and (c) negotiate in good faith any appropriate additional or supplementary terms or arrangements between the Parties to reflect the difference in the nature of the manufacturing process or supply chain for zavegepant. Unless otherwise mutually agreed between the Parties in writing, Licensor shall be responsible for executing on and funding such updated Development Plan. If Pfizer elects to Commercialize zavegepant, then Pfizer shall pay Licensor [***] within [***] for a Licensed Product containing zavegepant [***]. In the event Pfizer elects not to Commercialize zavegepant in the Field in the Territory in accordance with this Section 5.6 (Additional Commercialization Activities for Zavegepant), then, notwithstanding anything to the contrary in this Agreement, (i) zavegepant will no longer be a Licensed Compound under this Agreement and (ii) Licensor or any other person on its behalf shall be able to Develop, Manufacture and Commercialize zavegepant without any additional payment or other obligation to Pfizer.

5.7.Non-Compete. For the avoidance of doubt, obligations under this Section 5.7 (Non-Compete) shall cease to be effective upon any expiration or termination of this Agreement.

5.7.1.BMS Non-Compete Obligations.

(a)Restriction on Pfizer based on BMS Obligations. From the Effective Date through [***], neither Pfizer nor its Affiliates (nor any Sublicensee of Pfizer or any Affiliate of such Sublicensee) shall itself or through any Third Party, or in collaboration with any Third Party, engage, directly or indirectly in the clinical Development of a Competitive Compound or in the Commercialization of a Competitive Compound wherein the Competitive Compound has been investigated in a Clinical Trial (the time periods set forth in (a) and (b), the “Pfizer BMS Non-Compete Term”).

(b)Restriction on Licensor based on BMS Obligations. From the Effective Date through [***] (the “Biohaven BMS Non-Compete Term”), neither Licensor nor any of its Affiliates shall, itself or through any Third Party, or in collaboration with any Third Party, engage, directly or indirectly in the Commercialization of a Competitive Compound in the Acute Indication or Prevention Indication in the Field in the Territory wherein the Competitive Compound has been investigated in a Clinical Trial, except to the extent such Commercialization activities are permitted under [***]. For clarity, the non-compete restrictions on Licensor as set forth in this Section 5.7 (Non-Compete) shall not apply to zavegepant.

(c)Acquired Competitive Compound. Notwithstanding Section 5.7.1(a) (Restriction on Pfizer based on BMS Obligations) or Section 5.7.1(b) (Restriction on Licensor based on BMS Obligations), if Pfizer or its Affiliates, or any Sublicensee of either of them, or Biohaven or its Affiliates, as applicable (the “Acquiring Party”), either through its own development efforts or by acquisition, obtains ownership of or a license to, or is acquired by or otherwise merges with an entity (or an Affiliate of such entity) that owns or has a license to, a Competitive Compound, in all such cases that would result in a violation of Section 5.7.1(a) (Restriction on Pfizer based on BMS Obligations) during

-30-

the Pfizer BMS Non-Compete Term or a violation of Section 5.7.1(b) (Restriction on Licensor based on BMS Obligations) during the Biohaven BMS Non-Compete Term, as applicable (any such event, a “Triggering Event”), then the Acquiring Party shall promptly notify the other Party in writing and elect (as applicable) one of the following actions within [***] after such Triggering Event:

i.[***]; or

ii.[***].

5.7.2.Additional Non-Compete Obligations.

(a)Additional Commercialization Restriction on Pfizer. From [***] until [***], neither Pfizer nor its controlled Affiliates shall itself or through any Third Party, or in collaboration with any Third Party, engage, directly or indirectly in the Commercialization of a Competitive Compound in the Territory (such time period, the “Additional Pfizer Non-Compete Term”).

(b)Additional Commercialization Restriction on Licensor. From [***] until the [***] (the “Additional Licensor Non-Compete Term”), neither Licensor nor its controlled Affiliates shall, itself or through any Third Party, or in collaboration with any Third Party, engage, directly or indirectly in the Commercialization of a Competitive Compound in the Acute Indication or Prevention Indication in the Field in the Territory, [***]. For clarity, the non-compete restrictions on Licensor as set forth in this Section 5.7 (Non-Compete) shall not apply to zavegepant.

(c)Acquired Competitive Compound. Notwithstanding Section 5.7.2(a) (Additional Commercialization Restriction on Pfizer) or Section 5.7.2(b) (Additional Commercialization Restriction on Licensor), if Pfizer or its controlled Affiliates or Biohaven or its controlled Affiliates, as applicable (the “Acquiring Party”), either through its own development efforts or by acquisition, obtains ownership of or a license to, or is acquired by or otherwise merges with an entity (or an Affiliate of such entity) that owns or has a license to, a Competitive Compound, in all such cases that would result in a violation of Section 5.7.2(a) (Additional Commercialization Restriction on Pfizer) during the Additional Pfizer Non-Compete Term or a violation of Section 5.7.2(b) (Additional Commercialization Restriction on Licensor) during the Additional Biohaven Non-Compete Term, as applicable (any such event, a “Triggering Event”), then the Acquiring Party shall promptly notify the other Party in writing and elect (as applicable) one of the following actions within [***] after such Triggering Event:

i.[***], or

ii.[***].

(d)Independent Affiliate Activities. In the event that an Affiliate of a Party that is not a controlled Affiliate (an “Independent Affiliate”), is engaged, directly or indirectly, in any activities, that if carried by the Licensor or its non-Independent Affiliates or by Pfizer and its non-Independent Affiliates, as applicable, would be in violation of any of the restrictions set forth in Section 5.7.2 (Additional Non-Compete Obligations) (such activities, the “Competitive Activities”), then, [***]. In addition, if such Independent Affiliate is an Affiliate of Licensor’s, then Pfizer will have the right, at Pfizer’s sole election, to modify the information shared by the Parties through the JCC to exclude any information that would be commercially sensitive.

6.6.1.Third Party Rights. If it is [***], then Pfizer may, in its sole discretion, negotiate and obtain a license under such Patent Right(s) or Know-How (each such Third Party license referred to herein as an “Additional Third Party License”). Any royalty otherwise payable to Biohaven Ireland under this Agreement with respect to Net Sales of any Licensed Product by Pfizer, its Affiliates or Sublicensees will be reduced by [***] of the amounts payable to Third Parties pursuant to any Additional Third Party Licenses, such reduction to continue until all such amounts have been expended, provided that in no event (other than in the case of Licensor’s breach of any representation, warranty or covenant hereunder) will the total royalty payable to Biohaven for any Licensed Product in a Pfizer Quarter be less than [***] of the royalty amounts otherwise payable for such Licensed Product in such Pfizer Quarter as a result of such reduction for amounts payable pursuant to any Additional Third Party Licenses. Notwithstanding any provision to the contrary in this Agreement, in the event an Additional Third Party License is obtained as a result of a breach of any representation, warranty or covenant by Licensor hereunder and Pfizer seeks to reduce more than [***] of the royalty amounts otherwise payable for the applicable Licensed Product in such Pfizer Quarter as a result of amounts payable pursuant to such Additional Third Party License, then [***].

For any royalty otherwise payable to Biohaven Ireland under this Agreement with respect to Net Sales based on sales of a Licensed Product in a given country in the Biohaven Territory, subject to Section 6.6.5 (Cumulative Reduction Floor), any payments owed with respect to such Licensed Product in such country will be reduced by [***] for the remainder of the applicable Royalty Term (with such reduction to be pro-rated for the then-current Pfizer Quarter) upon the launch of a Generic Product that is sold in that country.

6.6.4.Valid Claim Stepdown. With respect to each Licensed Product in any particular country in the Biohaven Territory, if at any time such Licensed Product is not covered by a Valid Claim under a Biohaven Patent Right in such country, subject to Section 6.6.5 (Cumulative Reduction Floor), any payments owed with respect to such Licensed Product in such country shall be reduced by [***] for the remainder of the applicable Royalty Term upon the expiration of the last applicable Valid Claim, with such reduction to be pro-rated for the then-current Pfizer Quarter (the payment amounts reduced by this Section 6.6.4 (Valid Claim Stepdown), the “Biohaven Patent Stepdown Amount”).

6.6.5.Cumulative Reduction Floor. In no event will the aggregated royalty amount due to Biohaven Ireland in any given Pfizer Quarter during the Royalty Term for any Licensed Product in a country in the Biohaven Territory be reduced under this Section 6.6 (Royalty Adjustments) by more than [***] of the amount that otherwise would have been due and payable to Biohaven in such Pfizer Quarter for such Licensed Product in the Biohaven Territory under Section 6.5 (Royalties). Notwithstanding the foregoing, any excess amounts that would have otherwise been deducted in such Pfizer Quarter with respect to a Licensed Product shall be deducted from the royalty amounts payable to Pfizer in successive Pfizer Quarters until the earlier to (a) such excess amounts have been deducted in full or (b) the end of the Royalty Term.

6.7.Forecast. Pfizer shall provide on or before [***] of each Calendar Year a non-binding good faith forecast of sales and royalties for the entire current and next Calendar Year, which forecast will be provided in the format that exists as of such date.

6.11.2.Such books of accounting of Pfizer and its Affiliates shall be kept at their principal place of business and, with all necessary supporting data and records, shall during all reasonable

-36-

times for the [***] next following the end of the Pfizer Year to which each shall pertain, be open for inspection not more than [***] at reasonable times by an independent certified public accountant selected by Licensor and as to which Pfizer has no reasonable objection, at Licensor’s expense, for the purpose of verifying royalty statements and payments for compliance with this Agreement for any period within the preceding three Calendar Years.

6.11.3. The independent, certified public accountant shall disclose to Licensor only the amounts that the independent auditor believes to be due and payable hereunder to Licensor and details concerning any discrepancy from the amount paid (including the reasons therefor), and shall disclose no other information revealed in such audit.

6.11.4.Such accountant must have agreed in writing to maintain all information learned in confidence, except as necessary to disclose to Licensor under Section 6.11.3 (Sales Record Audit) such compliance or noncompliance by Pfizer and any Related Parties. The results of each inspection, if any, shall be binding on both Parties. Licensor shall pay for such inspections, except that in the event there is any upward adjustment in aggregate royalties payable for any Pfizer Year shown by such inspection of more than five percent of the amount paid, Pfizer shall pay for such inspection. Any underpayments shall be paid by Pfizer within [***] after notification of the results of such inspection. Any overpayments shall be fully creditable against amounts payable in subsequent payment periods.

6.11.5.For the avoidance of doubt, the results of such audit may be disclosed by Licensor to BMS pursuant to the terms of the BMS Agreement.

6.12.Interest on Late Payments.

Pfizer shall provide to Licensor reasonable illustrations of its standard exchange rate methodology promptly following the Effective Date.

6.14.Additional Payments and Allocation of Payments. For the avoidance of doubt, unless otherwise expressly stated, the payments by Pfizer to Licensor contemplated hereunder are in addition to, and not in lieu of, any payments owed by Pfizer to Licensor pursuant to [***]. [***] If the [***] is terminated and Pfizer is required to [***].

6.15.Taxes.

6.15.1.Taxes on Income, Tax Treatment. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the collaborative efforts of the Parties under this Agreement.

6.15.2.Payment of Tax. It is understood and agreed between the Parties that any payments made under this Agreement are exclusive of any value added or similar tax (“VAT”), which

-37-

shall be added thereon as applicable. Where VAT is properly added to a payment made under this Agreement, the Party making the payment will pay the amount of VAT only on receipt of a valid tax invoice issued in accordance with the laws and regulations of the country in which the VAT is chargeable. In the event any payments made pursuant to this Agreement become subject to withholding taxes under the Laws or regulation of any jurisdiction, the Party making such payment shall deduct and withhold the amount of such taxes for the account of the payee to the extent required by Laws and such amounts payable to the payee shall be reduced by the amount of taxes deducted and withheld.

The payee shall provide any tax forms to the Party making such payment that may be reasonably necessary in order for such Party 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, such recovery to be for the benefit of the Party bearing such withholding tax or VAT.

6.15.4.Additional Tax Liability. Notwithstanding anything in this Agreement to the contrary, if any assignment, or sublicense or a similar transfer of rights or obligations under this Agreement by a Party leads to the imposition of withholding tax liability on any amounts payable under this Agreement that would not have been imposed in the absence of such action or in an increase in such liability above the liability that would have been imposed in the absence of such action, then the sum payable by such Party (in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that the other Party receives a sum equal to the sum which it would have received had no such action occurred.

ARTICLE 7.

Intellectual Property

7.1.Ownership of Intellectual Property.

7.1.1.Subject to the licenses granted to Pfizer and Biohaven under Article 2 (Grant of Rights), the license granted to Pfizer under Section 14.1 (Grant to Pfizer) and Pfizer’s trademark rights in Section 7.6 (Product Marks), as between the Parties, each Party or its Affiliates will own all right, title and interest in and to: (a) any and all Know-How made in the conduct of activities under this Agreement (“Inventions”) solely by or on behalf of such Party or its Affiliates, (b) any and all Patent Rights claiming any such Inventions owned by such Party described in clause (a) of this Section 7.1.1 (Ownership of Intellectual Property) and (c) any and all Know-How, Patent Rights or other intellectual property rights that such Party owns as of the Effective Date or otherwise acquires during the Term. For the purposes of determining ownership under this Agreement, as applicable, inventorship will be determined in accordance with United States patent laws.

7.1.2.The Parties will jointly own any Inventions jointly invented (“Joint Inventions”) and, subject to the grant of licenses or sublicenses to Pfizer under Section 2.1 (Grant to Pfizer), each Party will be free to exploit, either itself or through the grant of licenses to Third Parties (which Third Party

-38-

licenses may be further sublicensed), Joint Inventions and Patent Rights claiming such Joint Inventions throughout the world without restriction, without the need to obtain further consent from or provide notice to the other Party, and without any duty to account or otherwise make any payment of any compensation to the other Party.

7.2.Employees, Consultants, Contractors. Each Party shall enter into binding agreements obligating all employees and consultants performing activities under or contemplated by this Agreement, including activities related to the Licensed Patent Rights, Licensed Compounds or Licensed Products, to assign his/her interest in any Invention made, discovered, conceived, or reduced to practice in the course of such activities to the Party for which such employee or consultant is providing its services, except consultants who by employment contract may only assign to their employers are treated as contractors for the purpose of this Section 7.2 (Employees, Consultants, Contractors). With respect to contractors, the Parties shall use good faith and reasonable efforts to secure an agreement from such contractor to assign or license (with the right to sublicense) to such Party any Inventions made by such contractor in performing such services for such Party.

7.3.Filing, Prosecution, and Maintenance of BMS Patent Rights, Licensed Patent Rights and Joint Patent Rights. As between the Parties, except as expressly set forth in this Section 7.3 (Filing, Prosecution, and Maintenance of BMS Patent Rights, Licensed Patent Rights and Joint Patent Rights), Licensor shall have the first right (but not the obligation), through counsel of its choice reasonably acceptable to Pfizer, to file, prosecute and maintain (a) the BMS Patent Rights and Licensed Patent Rights and any patentable inventions included within the BMS Know-How and Licensed Know-How at its own cost and expense and (b) any Patent Rights that claim or disclose any Joint Inventions (“Joint Patent Rights”). Pfizer shall assist and cooperate with Licensor, as Licensor may reasonably request from time to time, in the filing, prosecution and maintenance of the BMS Patent Rights, Licensed Patent Rights and Joint Patent Rights, and the Parties will confer regarding where to file and prosecute the BMS Patent Rights, Licensed Patent Rights and Joint Patent Rights, as applicable. Licensor will keep Pfizer advised on the status of the preparation, filing, prosecution, and maintenance of all patent applications and issued patents included within the BMS Patent Rights, Licensed Patent Rights and the Joint Patent Rights Licensor is prosecuting and maintaining. Further, Licensor will (i) allow Pfizer a reasonable opportunity and reasonable time to review and provide comments to Licensor’s counsel regarding relevant substantive communications to Licensor and drafts of any responses or other proposed substantive filings by Licensor before any applicable filings are submitted to any relevant patent office (or Governmental Authority) and (ii) reflect any reasonable and timely comments offered by Pfizer in any final filings submitted by Licensor to any relevant patent office (or Governmental Authority). If Licensor elects to cease the prosecution or maintenance of any BMS Patent Right, Licensed Patent Right or Joint Patent Right in any country, then Licensor will provide Pfizer with written notice of its decision not less than [***] before any action is required to avoid abandonment or lapse. If Pfizer elects to continue such prosecution or maintenance, which shall be at Pfizer’s sole cost and expense, then Pfizer will promptly identify and engage the attorneys and agents who will conduct further activities on Pfizer’s behalf and Licensor will reasonably cooperate to promptly transfer the necessary files and execute the necessary forms regarding such transfer. For the avoidance of doubt, any challenge to the ownership, validity, enforceability, or scope of any BMS Patent Rights, Licensed Patent Rights or any Joint Patent Rights filed in any patent office in any country in the Territory, such as an opposition, is excluded from this provision and is considered a challenge according to Section 7.4.1 (Enforcement and Defense of BMS Technology, Licensed Technology and Joint Inventions). Licensor (1) shall opt out, or shall cause BMS to opt out, of any and all BMS Patent Rights, Licensed Patent Rights and Joint Patent Rights that are European Patent Rights from the jurisdiction of the Unified Patent Court, and shall do so during the sunrise period for any European Patent Right granted before the Agreement on a Unified Patent Court comes into force, and (2) shall not file, or shall cause BMS to not file, at the European Patent Office any request for unitary effect

-39-

with respect to any BMS Patent Rights, Licensed Patent Rights and Joint Patent Rights that are European Patent Rights.

7.4.Enforcement and Defense of BMS Technology, Licensed Technology and Joint Inventions.

7.4.1.In the event that Licensor or Pfizer becomes aware of (a) any actual or suspected infringement, misappropriation, or other violation of or (b) any challenge to the ownership, validity, enforceability, scope, use of, in each case, any BMS Technology, Licensed Technology, or Joint Inventions, in each case, relating to Licensed Compounds or Licensed Products or their manufacture, sale or use in any country of the Territory, such Party shall notify the other Party promptly, and provide all information available to such Party with respect to such alleged infringement, misappropriation, other violation or challenge and following such notification, the Parties shall promptly confer. Pfizer shall have the first right, but shall not be obligated, to, as applicable, defend a challenge or bring an action for infringement, misappropriation or other violation at its own cost and expense, in its own name and entirely under its own direction and control, in any (x) Major Market; (y) any country in the Territory where there has been a First Commercial Sale of a Licensed Product; and (z) any other country in the Territory, provided that in the case of clause (z) [***], in each case of clauses (x), (y) and (z), subject to the following: (i) Pfizer will reasonably consult with Licensor in any such action or proceeding and will in good faith consider and implement any reasonable suggestions by Licensor with respect thereto; (ii) Licensor shall reasonably assist Pfizer (and Pfizer shall reimburse Licensor for its reasonable and documented out-of-pocket costs and expenses incurred in connection with such assistance) in any such action or proceeding (including any related actions or proceedings outside the Territory), including by being named or joined as a plaintiff to such actions or proceedings if required under Law and by exercising its rights under the BMS Agreement to seek BMS’s assistance (including for BMS to be named or joined as a plaintiff to such actions or proceedings if required under Law) in any such action or proceeding if requested by Pfizer; (iii) Licensor shall have the right to participate and be represented in any such suit by its own counsel at its own cost and expense; and (iv) no settlement of any such action or proceeding which adversely affects the ownership, scope, duration, validity, or enforceability of a BMS Patent Right, Licensed Patent Right or Joint Patent Right may be entered into by Pfizer without the prior written consent of Licensor, which consent shall not be unreasonably withheld, delayed or conditioned.

7.4.2.If (a) [***] in Section 7.4.1 (Enforcement and Defense of BMS Technology, Licensed Technology and Joint Inventions), or (b) following a written request from Licensor, Pfizer declines or fails within 15 Business Days following the receipt of such request to defend or enforce any BMS Technology, Licensed Technology or Joint Invention in any country in the Territory, Licensor shall have the right to notify Pfizer of Licensor’s intent to take over defense or enforcement. In each case, Licensor may then initiate and conduct any action or proceeding relating to such defense or enforcement; provided, however, that, (i) Licensor will reasonably consult with Pfizer in any such action or proceeding and will in good faith consider and implement any reasonable suggestions by Pfizer with respect thereto; (ii) Pfizer shall reasonably assist Licensor (and Licensor shall reimburse Pfizer for its reasonable and documented out-of-pocket costs and expenses incurred in connection with such assistance) if so requested, including by being named or joined as a plaintiff to such actions or proceedings if required under Law; (iii) Pfizer shall have the right to participate and be represented in any such suit by its own counsel at its own cost and expense; and (iv) no settlement of any such action or proceeding which adversely affects the ownership, scope, duration, validity, or enforceability of a BMS Patent Right, Licensed Patent Right or a Joint Patent Right in the Field in the Territory (and with respect to Patent Rights relating solely to rimegepant, in the Acute Indication, Prevention Indication or any Additional Indications for which Pfizer has elected to Commercialize pursuant to Section 4.2.4(b) (Additional

-40-

Indications for Rimegepant)) may be entered into by Licensor without the prior written consent of Pfizer, which consent shall not be unreasonably withheld, delayed or conditioned.

7.5.Damages. In the event that either Party exercises the rights conferred in Section 7.4 (Enforcement and Defense of BMS Technology, Licensed Technology and Joint Inventions) and recovers any damages or other sums in such action or proceeding or in settlement thereof, such damages or other sums recovered shall [***].

7.6.Product Marks.

Licensor shall indemnify, defend and hold harmless Pfizer and its Affiliates, and their respective officers, directors, employees, agents, and their respective successors, heirs and assigns, from and against any and all Losses and Claims to the extent arising out of or relating to: (a) the Development of any Licensed Compound or Licensed Product by or on behalf of Licensor or any of its Affiliates, (sub)licensees, agents and contractors; (b) the breach by Licensor of the BMS Agreement, except to the extent caused by Pfizer’s breach of this Agreement or the BMS Sublicense; (c) the breach by Licensor of any of its representations, warranties or covenants set forth in Article 9 (Representations and Warranties); (d) the breach by Licensor of the Prior Agreements or the Distribution Agreements; and (e) the gross negligence or willful misconduct of Licensor or its Affiliates or its or their respective directors, officers, employees and agents, in connection with Licensor’s performance of its obligations or exercise of its rights under this Agreement, except in any such case of clauses (a) through (e), for Losses and Claims to the extent reasonably attributable to (x) any breach by Pfizer, (y) a claim for which Pfizer is required to indemnify Licensor pursuant to Section 10.1 (Pfizer Indemnity) or (z) Pfizer having committed an act or acts of gross negligence or willful misconduct.

10.3.Indemnification Procedure. A claim to which indemnification applies under this Article 10 (Indemnity; Limitation of Liability) shall be referred to herein as an “Indemnification Claim”. If any Person or Persons (collectively, the “Indemnitee”) intends to claim indemnification under this Article 10 (Indemnity; Limitation of Liability), the Indemnitee shall notify the Party subject to the indemnification obligation (the “Indemnitor”) in writing promptly upon becoming aware of any claim that may be an Indemnification Claim (it being understood and agreed, however, that the failure by an Indemnitee to give such notice shall not relieve Indemnitor of its indemnification obligation under this Agreement except and only to the extent that the Indemnitor is actually prejudiced as a result of such failure to give notice). The Indemnitor shall have the right to assume and control the defense of the Indemnification Claim at its own expense with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee; provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other party represented by such counsel in such proceedings. If the Indemnitor does not assume the defense of the Indemnification Claim as aforesaid, the Indemnitee may defend the Indemnification Claim but shall have no obligation to do so. The Indemnitee shall not settle or compromise the Indemnification Claim without the prior written consent of the Indemnitor, and the Indemnitor shall not settle or compromise the Indemnification Claim in any manner which would have an adverse effect on the Indemnitee’s interests (including any rights under this Agreement or the scope or enforceability of the BMS Technology or Licensed Technology), without the prior written consent of the Indemnitee, which consent, in each case, shall not be unreasonably withheld, delayed or conditioned. The Indemnitee shall reasonably cooperate with the Indemnitor at the Indemnitor’s expense and shall make available to the Indemnitor all pertinent information under the control of the Indemnitee, which information shall be subject to Article 8 (Confidentiality and Non-Disclosure).

10.4.LIMITATION OF LIABILITY. EXCEPT WITH RESPECT TO LIABILITY ARISING FROM ANY WILLFUL MISCONDUCT, FRAUDULENT OR INTENTIONALLY WRONGFUL ACT, OR TO THE EXTENT SUCH PARTY MAY HAVE AN INDEMNIFICATION OBLIGATION UNDER THIS ARTICLE 10 (INDEMNITY; LIMITATION OF LIABILITY), IN NO EVENT WILL EITHER PARTY OR ITS AFFILIATES BE LIABLE UNDER THIS AGREEMENT FOR ANY SPECIAL (ONLY AS RELATED TO INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES), INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, WHETHER IN CONTRACT, WARRANTY, TORT, NEGLIGENCE, STRICT LIABILITY OR OTHERWISE.

-51-

10.5.Insurance. Each Party shall maintain at all times during the term of this Agreement and for [***] thereafter maintain such types and amounts of liability insurance that is reasonably sufficient to cover liabilities related to its activities under this Agreement as is normal and customary in the pharmaceutical industry for persons similarly situated. Notwithstanding any provision of this Section 10.5 (Insurance) to the contrary, Pfizer may meet its obligations under this Section 10.5 (Insurance) through self-insurance. Neither Party’s insurance will be construed to create a limit of liability with respect to its indemnification obligations under this Article 10 (Indemnity; Limitation of Liability).

10.6.Joint and Several Liability; Guarantee. Notwithstanding anything to the contrary in this Agreement, each of Biohaven HoldCo and Biohaven Ireland shall be liable to Pfizer, on a joint and several basis, for full performance of each such Party’s obligations and covenants under this Agreement. Biohaven HoldCo and Biohaven Ireland hereby absolutely, unconditionally and irrevocably guarantee, jointly and severally, as primary obligors and not merely as sureties, to Pfizer the full payment and performance of BioShin’s obligations under this Agreement on the terms and subject to the conditions in this Agreement, and, to the fullest extent permitted by Law, waive and relinquish all rights and defenses accorded by Law to sureties and/or guarantors or any other accommodation parties, including diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of BioShin, any right to require a proceeding first against BioShin, protest, notice and all demands whatsoever. Until all obligations of BioShin under this Agreement have been fully and finally paid and performed, Biohaven Holdco and Biohaven Ireland waive all rights of subrogation, reimbursement, indemnification, contribution, or similar right or remedy against BioShin or any other guarantor. This is an absolute, present and continuing guaranty of payment and performance and not merely of collection.

ARTICLE 11.

Effectiveness

11.1.Effectiveness of the Agreement. Except for the Parties’ rights and obligations under Article 8 (Confidentiality and Non-Disclosure), Article 9 (Representations and Warranties), Section 13.1 (Governing Law), Section 13.2 (Dispute Resolution), Section 13.3 (Jurisdiction) and this Article 11 (Effectiveness), which will be effective as of the Execution Date, this Agreement will not become effective until the Effective Date. Upon the occurrence of the Effective Date, all other provisions of this Agreement shall become effective automatically without the need for further action by the Parties. Notwithstanding any other provisions of this Agreement to the contrary, if (a) any Governmental Authority obtains a permanent order or injunction under any Foreign Antitrust Laws against Licensor or Pfizer to enjoin the transactions contemplated by this Agreement or (b) the Effective Date has not occurred within [***] after the Execution Date, then either Party may terminate this Agreement upon written notice to the other Party, and this Agreement will be void and of no further effect.

11.2.Governmental Approvals.

11.2.1.Antitrust Filings. Each of Licensor and Pfizer will cooperate with each other and use (and shall cause their respective Affiliates to use) their respective commercially reasonable efforts to take or cause to be taken all actions necessary or advisable on its part under this Agreement and Law to make effective the transactions contemplated by this Agreement as promptly as possible after the Execution Date, including, within [***] after the Execution Date (or such later time as may be agreed to in writing by the Parties), making or submitting all Antitrust Filings with the applicable Governmental Authorities. The Parties will cooperate with one another to the extent necessary in the preparation of any such Antitrust Filings and shall (a) respond as promptly as practicable to any inquiries or requests for documentation or information or any request for additional information received from any Governmental

-52-

Authority in connection with an Antitrust Filing, (b) use their respective commercially reasonable efforts to resolve objections, if any, as may be asserted by any Governmental Authority with respect to the transactions contemplated under this Agreement under any Foreign Antitrust Laws and to prevent or lift any injunction or other legal bar to the consummation of the transactions contemplated under this Agreement, and (c) use their respective commercially reasonable efforts to cause the waiting periods, approvals or other requirements under any Foreign Antitrust Laws to terminate or expire or be obtained as promptly as reasonably practicable. None of the Parties shall knowingly take, cause or permit to be taken any action which would reasonably be expected to materially delay or prevent consummation or effectiveness of the transactions contemplated under this Agreement. Neither Licensor nor Pfizer will agree to any voluntary extension or delay of any statutory waiting period or withdraw any of its Antitrust Filings pursuant to any Foreign Antitrust Laws unless the other Party has given its prior written consent to such extension or delay. Licensor and Pfizer shall each keep the other Party informed in all material respects and on a reasonably timely basis of any material communication received by such Party from, or given by such Party to, any other Governmental Authority in connection with an Antitrust Filing. Licensor and Pfizer shall each consult with the other Party and consider in good faith the views of the other Party prior to entering into any agreement, arrangement, undertaking or understanding (whether oral or written) with any Governmental Authority relating to any Foreign Antitrust Laws with respect to the transactions contemplated under this Agreement; provided, however, that the final determination as to the appropriate course of action will be made by Pfizer. Each Party will be responsible for its own costs, expenses, and filing fees associated with any Antitrust Filing; provided, however, that Pfizer will be solely responsible for any fees (other than penalties that are incurred solely as a result of actions or omissions on the part of Licensor) required to be paid to any Governmental Authority in connection with making any such Antitrust Filing.

11.2.2.Other Government Approvals. Each of Licensor and Pfizer will cooperate with the other Parties and use its reasonable best efforts to do all other things necessary, proper or desirable for the consummation of the transactions contemplated under this Agreement, including using reasonable best efforts to (a) make all necessary registrations, filings and applications, (b) give all necessary notices, (c) obtain as soon as practicable all necessary governmental or other actions or non-actions, consents, transfers, approvals, orders, qualifications, authorizations, permits and waivers and (d) defend any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Authority vacated or reversed.

ARTICLE 12.

Term and Termination

12.1.Term. This Agreement shall commence as of the Effective Date and, unless sooner terminated in accordance with the terms hereof or by mutual written consent, shall expire on a country-by-country basis and Licensed Product-by-Licensed Product basis, upon the expiration of the Royalty Term with respect to a given Licensed Product in the applicable country (the “Term”).

12.2.Termination of BMS Sublicense. This Agreement shall automatically and immediately terminate upon the termination (but for clarity, not the expiration) of the BMS Sublicense, unless Pfizer elects to become a “Surviving Sublicensee” in accordance with the terms and conditions of the BMS Consent Letter, BMS Sublicense and BMS Agreement.

12.3.Termination by Pfizer.

-53-

12.3.1.Insolvency. To the extent permitted under Laws, Pfizer shall have the right to terminate this Agreement in its entirety, at its sole discretion, upon delivery of written notice to Licensor upon (a) the filing by any other Party in any court or agency pursuant to any statute or regulation of the United States or any other jurisdiction a petition in bankruptcy or insolvency or for reorganization or similar arrangement for the benefit of creditors; (b) the appointment of a receiver or trustee of any other Party or its assets; (c) the proposal by any other Party of a written agreement of composition or extension of its debts; (d) the making by any other Party of an assignment for the benefit of its creditors; or (e) if any other Party is served by a Third Party with an involuntary petition against it in any insolvency proceeding, upon the [***] after such service if such involuntary petition has not previously been stayed or dismissed.

12.3.2.Material Breach. If Pfizer believes that Licensor is in Material Breach, then in addition to any other right and remedy Pfizer may have, Pfizer may deliver notice of such Material Breach to Licensor that specifies the breach and its claim of right to terminate (the “Termination Notice”). With regard to any Material Breach by Licensor, Pfizer shall have [***] (the “Notice Period”) following the receipt of such Termination Notice to cure such Material Breach, provided that for all Material Breaches other than a payment breach, if such breach cannot be reasonably cured during such [***] period but is capable of cure within [***], then Licensor may submit to Pfizer a reasonable cure plan to remedy such Material Breach that is reasonably acceptable to Pfizer, and upon such submission, the applicable cure period will automatically be extended for so long as Licensor continues to use commercially reasonable efforts to cure such Material Breach in accordance with such cure plan, but for no more than [***] from receipt of such Termination Notice (subject to the dispute resolution procedures set forth in Section 12.5 (Disputes Regarding Material Breach) below).

12.3.3.Termination at Will. Pfizer may terminate this Agreement on a Licensed Product-by-Licensed Product basis or in its entirety, for any reason or no reason, upon 180 days’ prior written notice to Licensor.

12.4.Termination by Licensor.

12.4.1.Insolvency. To the extent permitted under Laws, Licensor shall have the right to terminate this Agreement in its entirety, at its sole discretion, upon delivery of written notice to Pfizer upon (a) the filing by Pfizer in any court or agency pursuant to any statute or regulation of the United States or any other jurisdiction a petition in bankruptcy or insolvency or for reorganization or similar arrangement for the benefit of creditors; (b) the appointment of a receiver or trustee of Pfizer or its assets; (c) the proposal by Pfizer of a written agreement of composition or extension of its debts; (d) the making by Pfizer of an assignment for the benefit of its creditors; or (e) if Pfizer is served by a Third Party with an involuntary petition against it in any insolvency proceeding, upon the [***] after such service if such involuntary petition has not previously been stayed or dismissed.

12.4.2.Material Breach. If Licensor believes that Pfizer is in Material Breach, then in addition to any other right and remedy Licensor may have, Licensor may deliver a Termination Notice to Pfizer. With regard to any Material Breach by Pfizer, Pfizer shall have the Notice Period following the receipt of such Termination Notice to cure such Material Breach, provided that for all Material Breaches other than a payment breach, if such breach cannot be reasonably cured during such [***] period but is capable of cure within [***], then Pfizer may submit to Licensor a reasonable cure plan to remedy such Material Breach that is reasonably acceptable to Licensor, and upon such submission, the applicable cure period will automatically be extended for so long as Pfizer continues to use commercially reasonable efforts to cure such Material Breach in accordance with such cure plan, but for no more than [***] from

-54-

receipt of such Termination Notice (subject to the dispute resolution procedures set forth in Section 12.5 (Disputes Regarding Material Breach) below).

12.5.Disputes Regarding Material Breach. In each case of Section 12.3.2 (Termination by Pfizer – Material Breach) or Section 12.4.2 (Termination by Licensor – Material Breach), the allegedly breaching Party may dispute occurrence of such Material Breach, and in such case the allegedly breaching Party shall give written notice of such dispute no later than [***] after its receipt of the Termination Notice and the issue of whether the applicable Party may properly terminate this Agreement on expiration of the applicable cure period will be resolved in accordance with Section 13.2 (Dispute Resolution). If as a result of such dispute resolution process, it is determined that the allegedly breaching Party committed a Material Breach and the allegedly breaching Party does not cure such Material Breach within (a) [***] in the case of a failure to make a payment set forth in this Agreement or (b) [***] in the case of any other Material Breach, as applicable, after the date of such determination (the “Additional Cure Period”), then such termination will be effective as of the expiration of the Additional Cure Period. This Agreement will remain in full force and effect during the pendency of any such dispute resolution proceeding and the cure periods set forth in this Section 12.5 (Disputes Regarding Material Breach), and any Additional Cure Period, in each case, will be tolled during any such dispute resolution proceeding, such proceeding will not suspend any obligations of either Party hereunder, and each Party will use reasonable efforts to mitigate any damage. If as a result of such dispute resolution proceeding it is determined that the allegedly breaching Party did not commit a Material Breach, then no termination will be effective, and this Agreement will continue in full force and effect.

12.6.Effect of Termination. Upon termination (but for clarity, not expiration) of this Agreement:

12.6.1.All rights and licenses granted to Pfizer (including the exclusive license in Section 2.1 (Grant to Pfizer) and Section 14.1 (Grant to Pfizer), the co-exclusive copyright license granted in Section 7.6.4(a) (Copyrights) and any trademark licenses granted pursuant to Section 7.6 (Product Marks)) with respect to the Terminated Products shall terminate in the Territory, and all rights to the BMS Technology and Licensed Technology with respect to the Terminated Products in the Territory (a) that was in the Biohaven Territory with respect to the Terminated Products shall revert to Biohaven and; and (b) that was in the BioShin Territory shall revert to BioShin.

12.6.2.Following the effective date of such termination, all Terminated Products in the form they are in as of such effective date of termination shall thereafter be deemed “Reversion Products”. Except upon a termination for Biohaven’s material breach pursuant to 12.3.2 (Material Breach), for each Reversion Product, Pfizer hereby grants to Licensor an irrevocable, perpetual, [***] non-exclusive license (where such license is solely sublicensable to Biohaven’s Affiliates and designees and service providers and solely transferable in connection with a sale or transfer of all or substantially all of the business to which it relates on a country-by-country basis) under the Pfizer IP to Develop, Manufacture or Commercialize such Reversion Products in the Field anywhere in the world.

12.6.3.Except upon a termination for Biohaven’s material breach pursuant to 12.3.2 (Material Breach): (a) to the extent not already in Biohaven’s possession, Pfizer shall provide to Biohaven a tangible embodiment of any Know-How that is (i) an Invention; (ii) Controlled by Pfizer or any if its Affiliates; and (iii) used by Pfizer, any of its Affiliates or Sublicensees at the time of termination in the Development, Manufacture or Commercialization of Terminated Products (the “Reversion Know-How”); and (b) Pfizer hereby grants to Biohaven an irrevocable, perpetual, [***] non-exclusive license (where such license is solely sublicensable to Biohaven’s Affiliates and designees and service providers

-55-

and solely transferable in connection with a sale or transfer of all or substantially all of the business to which it relates on a country-by-country basis) under the Reversion Know-How to Develop, Manufacture or Commercialize the Reversion Products in the Field anywhere in the world.

12.6.4.In the event of termination for Biohaven’s material breach pursuant to 12.3.2 (Material Breach), upon Biohaven’s request, the Parties will negotiate in good faith for a period not to exceed [***] after the effective date of such termination, the grant by Pfizer to Licensor of a royalty-bearing, non-exclusive license (where such license is solely sublicensable to Biohaven’s Affiliates and designees and service providers and solely transferable in connection with a sale or transfer of all or substantially all of the business to which it relates on a country-by-country basis) under the Pfizer IP and under the Reversion Know-How to Develop, Manufacture or Commercialize the Licensed Product in the Field anywhere in the world.

12.6.5.All amounts due or payable to Licensor that were accrued, or that arise out of acts or events occurring, prior to the effective date of termination shall remain due and payable.

12.6.6.Should Pfizer have any unsold inventory of any Licensed Product included in the Reversion Products purchased from Biohaven prior to termination, Pfizer shall offer to sell such Licensed Product to Biohaven or its designee at the fully burdened manufacturing cost of such Licensed Product (but Biohaven or its designee shall be under no obligation to purchase same unless it agrees to do so in writing at such time); provided that Pfizer shall have no obligation to offer to sell Licensed Product to Biohaven if this Agreement is terminated under Section 12.3.2 (Termination by Pfizer – Material Breach).

12.6.7.If Biohaven or its designee does not elect within [***] of offer, or does not have the option, to purchase the Licensed Products as set forth in Section 12.6.6 (Effect of Termination), then Pfizer shall have six months thereafter in which to dispose of such inventory (subject to the payment to Licensor of any royalties or other payments due hereunder thereon); provided that such Licensed Product shall not be sold at a discount to a purchaser that is greater than the average discount provided to such purchaser for the Licensed Product in the applicable country during the 12-month period preceding such termination.

12.6.8.To the extent that Pfizer or any of its Affiliates owns any Pfizer Product Marks that pertain specifically to a Reversion Product and such Pfizer Product Xxxx is necessary for the Commercialization of such Reversion Product in the Territory (as then currently marketed, but not including any marks that include, in whole or part, any corporate name or logo of Pfizer), Pfizer shall assign (or, if applicable, cause its Affiliate to assign) to Biohaven all of Pfizer’s (and such Affiliate’s) right, title and interest in and to any such Pfizer Product Xxxx. Licensor shall be responsible for preparing and filing all instruments and documents necessary to effect the assignment of the Pfizer Product Marks to Licensor required under this Section 12.6.8, including all costs and expenses of preparing and recording country-specific assignments and legalization of signatures (where required).

12.6.9. Pfizer shall assign and transfer, and hereby does assign and transfer, to Biohaven or its designee all of Pfizer’s rights, title, and interests in and to any Educational Materials and Marketing Materials, and all other Commercialization Materials related to the Reversion Products, including copyrights embodied in the foregoing and any registrations for the foregoing.

12.6.10. Effective upon the effective date of termination of this Agreement, Pfizer shall, use Commercially Reasonable Efforts to assign to Licensor or its designee all regulatory filings (including all INDs and NDAs) and Regulatory Approvals and all other material regulatory documents, including

-56-

copies of all material correspondence and conversation logs, pre-clinical and clinical study reports, clinical study protocols, in each case, that are solely applicable to the Reversion Products in the Territory and Controlled by Pfizer or its Affiliates (collectively, the “Reversion Regulatory Materials”). With respect to Reversion Regulatory Materials that are not assigned as set forth above, Pfizer shall hold such Reversion Regulatory Materials in its name for the benefit of Licensor and hereby does grant to Licensor an exclusive, royalty-free license and right of reference to use such Reversion Regulatory Materials in connection with the Commercialization, Development and Manufacture of the Reversion Products in the Territory and authorize Licensor to conduct regulatory activities with applicable Regulatory Authorities relating to such Reversion Regulatory Materials. For the avoidance of doubt, such right of access and reference may be assigned or sublicensed by Licensor to any designee of Licensor or to BMS.

12.6.11. Neither Party shall be relieved of any obligation that accrued prior to the effective date of such termination or expiration. Nothing in this Section 12.6 (Effect of Termination) shall be deemed to limit any remedy to which either Party may be entitled by Law.

12.7.Survival. The following provisions shall survive termination or expiration of this Agreement, as well as any other provisions which by their nature are intended to survive termination: Article 1 (Definitions) (as applicable), Article 3 (Governance) (solely with respect to any outstanding decisions and disputes at the time of termination or expiration), Article 6 (Payments and Records) (solely with respect to any outstanding payments at the time of termination or expiration), Article 8 (Confidentiality and Non-Disclosure), Article 10 (Indemnity; Limitation of Liability) and Article 13 (Miscellaneous), and Sections 2.5 (Reservation of Rights), 7.1 (Ownership of Intellectual Property), 7.3 (Filing, Prosecution, and Maintenance of BMS Patent Rights, Licensed Patent Rights and Joint Patent Rights), 7.4 (Enforcement and Defense of BMS Technology, Licensed Technology and Joint Inventions) (solely with respect to any ongoing actions at the time of termination or expiration), 7.5 (Damages), 7.6 (Product Marks), 7.7 (Third Party Rights), 7.8 (Joint Research Agreement), 9.5 (Disclaimer), 12.6 (Effect of Termination), this 12.7 (Survival), 12.8 (Bankruptcy) and 14.3 (Commercial Milestone) through 14.5 (Royalty Adjustments) (solely with respect to any outstanding payments that have accrued at the time of termination or expiration).

12.8.Bankruptcy. All rights and licenses now or hereafter granted by Licensor to Pfizer under or pursuant to any Section of this Agreement, are rights to “intellectual property” (as defined in the United States Bankruptcy Code (the “Bankruptcy Code”)). The Parties hereto acknowledge and agree that the payments by Pfizer to Licensor hereunder, other than royalty payments and sales milestones pursuant to Section 6.4 (Sales Milestones) and Section 6.5 (Royalties) and Exhibit A, do not constitute royalties within the meaning of Section 365(n) of the Bankruptcy Code or relate to licenses of intellectual property hereunder. If (a) a case under the Bankruptcy Code is commenced by or against Licensor, (b) this Agreement is rejected as provided in the Bankruptcy Code and (c) Pfizer elects to retain its rights hereunder as provided in Section 365(n) of the Bankruptcy Code, then subject to Law, Licensor (in any capacity, including debtor-in-possession) and its successors and assigns (including any trustee) will provide to Pfizer access to tangible embodiments of Know-How licensed hereunder, and agrees to grant and hereby grants to Pfizer and its Affiliates a right to access and to obtain possession of and to benefit from and, in the case of any chemical or biological material or other tangible item of which there is a fixed or limited quantity, to obtain a pro rata portion of, each of the following (but in each case, only to the extent necessary for Pfizer to exercise any right or license granted under or pursuant to this Agreement): (i) copies of pre-clinical and clinical research data and results; (ii) samples of biological materials; (iii) copies of laboratory notes and notebooks; (iv) Licensed Technology in the Territory; (v) copies of Licensed Product data or filings; and (vi) Rights of Reference in respect of regulatory filings and approvals in the Territory, all of which constitute “embodiments” of intellectual property pursuant to Section 365(n) of the Bankruptcy Code, whether any of the foregoing are in Licensor’s possession or

-57-

control or in the possession and control of any Third Party but which Licensor has the right to access or benefit from and to make available to Pfizer. Licensor will not interfere with the exercise by Pfizer or its Affiliates of rights and licenses to intellectual property in the Territory licensed hereunder and embodiments thereof in accordance with this Agreement and agrees to use Commercially Reasonable Efforts to assist Pfizer and its Affiliates to obtain such intellectual property and embodiments thereof in the possession or control of Third Parties as reasonably necessary or desirable for Pfizer or its Affiliates or Sublicensees to exercise such rights and licenses in the Territory in accordance with this Agreement. The Parties agree that in the event a Party becomes a debtor under Title 11 of the U.S. Code (“Title 11”), this Agreement shall be deemed to be, for purposes of Section 365(n) of Title 11, a license to rights to “intellectual property” as defined therein. Each Party as a licensee hereunder shall have the rights and elections as specified in Title 11. Any agreements supplemental hereto shall be deemed to be “agreements supplementary to” this Agreement for purposes of Section 365(n) of Title 11. All rights, powers and remedies of either Party provided in Section 12.3.1 (Termination by Pfizer – Insolvency), Section 12.3.1 (Termination by Licensor—Insolvency) and this Section 12.8 (Bankruptcy) are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at Law or in equity (including the Bankruptcy Code) in the event of the commencement of a case under the Bankruptcy Code involving Licensor or Pfizer, as applicable.

Exhibit A

ARTICLE 14.

BioShin Terms

14.1.Grant to Pfizer.

14.1.1.As of the Effective Date, subject to the terms and conditions of this Agreement, BioShin hereby grants to Pfizer an exclusive (even as to BioShin and its Affiliates) license under the BioShin Patent Rights and BioShin Know-How, with the right to grant sublicenses solely in accordance with Section 14.2 (Sublicenses), to Commercialize the Licensed Compounds and Licensed Products in the Field in the Territory.

14.2.Sublicenses. Pfizer may grant sublicenses, solely within the scope of the licenses granted to Pfizer pursuant to Section 14.1 (Grant to Pfizer) to any (a) Affiliate; provided that any sublicense granted to an Affiliate shall automatically and immediately terminate once such Person ceases to be an Affiliate of Pfizer; or (b) Third Party; provided that any sublicense under the rights granted in Section 14.1 (Grant to Pfizer) to a Third Party who is not a distributor, wholesaler, reseller or other service provider, in each case, performing services on behalf of Pfizer pursuant to the terms and conditions of this Agreement will require BioShin’s prior written consent, not to be unreasonably withheld, delayed or conditioned.

14.3.Commercial Milestone. Pfizer shall pay to BioShin the following one time milestone payment set forth in the table below within [***] after the first achievement of the specified milestone event by Pfizer, its Affiliates, or any Sublicensee of either of them.

Milestone			Payment
[***]			[***]

14.4.Royalties.

14.4.1.BioShin Royalty Term. Royalties shall be payable on a Licensed Product-by-Licensed Product and country-by-country basis on Net Sales of Licensed Products from the First Commercial Sale of a particular Licensed Product in a country in the BioShin Territory until the later of

(a) 10 years after the First Commercial Sale of such Licensed Product in such country; (b) the expiration of the last to expire of a Valid Claim of a Licensed Patent Right that would be infringed by the use, sale, importation or offer for sale in such country of a given Licensed Product; or (c) the expiration of any Data Exclusivity for such Licensed Product in such country (the “BioShin Royalty Term”). Following the expiration of the BioShin Royalty Term, on a country-by-country and Licensed Product-by-Licensed Product basis, no further royalties will be payable in respect of sales of such Licensed Product in such country and thereafter the license granted to Pfizer pursuant to Section 14.1 (Grant to Pfizer) shall become non-exclusive, fully paid-up, irrevocable, perpetual, and royalty-free; provided, however, [***].

14.4.2.Royalty Rates. Pfizer shall pay to BioShin tiered royalties based on the total annual Net Sales in the Territory of each Licensed Product (including all indications and formulations for such Licensed Product, and calculated in the aggregate for all Net Sales in the Territory of such Licensed Product made by Pfizer, its Affiliates or any Sublicensee of either of them under this Agreement and the BMS Sublicense) during the applicable BioShin Royalty Term in such country for such Licensed Product; provided, however, [***]; provided, further, [***]. The royalty payable with respect to each particular Licensed Product shall be calculated by multiplying the applicable royalty rate below by the portion of total annual Net Sales in the BioShin Territory in the applicable tier in a Pfizer Year of the applicable Licensed Product by Pfizer, its Affiliates, and Sublicensees in the BioShin Territory, as follows:


Total Annual Net Sales for a Licensed Product (in a Pfizer Year)
Net Sales			Royalty Rate
[***]			[***]
[***]			[***]
[***]			[***]
[***]			[***]

14.5.Royalty Adjustments. The following adjustments will be made, on a Licensed Product-by-Licensed Product and country-by-country basis, to the royalty payable pursuant to Section 14.4 (Royalties):

14.5.1.Third Party Rights. If [***], then Pfizer may negotiate and obtain a license under such Patent Right(s) or Know-How (each such Third Party license referred to herein as a “BioShin Additional Third Party License”). Any royalty otherwise payable to BioShin under this Agreement with respect to Net Sales of any Licensed Product by Pfizer, its Affiliates or Sublicensees will be reduced by [***] of the amounts payable to Third Parties pursuant to any BioShin Additional Third Party Licenses, such reduction to continue until all such amounts have been expended, provided that in no event (other than in the case of Licensor’s breach of any representation, warranty or covenant hereunder) will the total royalty payable to BioShin for any Licensed Product in a Pfizer Quarter be less than [***] of the royalty amounts otherwise payable for such Licensed Product in such Pfizer Quarter. Notwithstanding any provision to the contrary in this Agreement, in the event a BioShin Additional Third Party License is obtained as a result of a breach of any representation, warranty or covenant by Licensor hereunder and Pfizer seeks to reduce more than [***] of the royalty amounts otherwise payable for the applicable Licensed Product in such Pfizer Quarter as a result of amounts payable pursuant to such Additional Third Party License, then [***].

14.5.2.No Adjustment for Existing Third Party Agreements and Inventor Compensation in the Territory. Each Party will be solely responsible for all obligations under any existing Third Party agreements to which it is a party or any agreements that such Party enters into with a Third Party during the Term, subject to Section 14.5.1 (Third Party Rights) and the BMS Sublicense. Each Party shall be

solely responsible for all payments to its own inventors of its respective intellectual property, as applicable, including payments under inventorship compensation laws.

14.5.3.Generic Entry. For any royalty otherwise payable to BioShin under this Agreement with respect to Net Sales based on sales of a Licensed Product in a given country in the BioShin Territory, subject to Section 14.5.5 (Cumulative Reduction Floor), any payments owed with respect to such Licensed Product in such country will be reduced by [***] for the remainder of the applicable BioShin Royalty Term (with such reduction to be pro-rated for the then-current Pfizer Quarter) upon the launch of a Generic Product that is sold in that country.

14.5.4.Valid Claim Stepdown. With respect to each Licensed Product in any particular country in the BioShin Territory, if at any time such Licensed Product is not covered by a Valid Claim under a BioShin Patent Right in such country, subject to Section 14.5.5 (Cumulative Reduction Floor), any payments owed with respect to such Licensed Product in such country shall be reduced by [***] for the remainder of the applicable BioShin Royalty Term upon the expiration of the last applicable Valid Claim, with such reduction to be pro-rated for the then-current Pfizer Quarter (the payment amounts reduced by this Section 14.5.4 (Valid Claim Stepdown), the “BioShin Territory Biohaven Patent Stepdown Amount”).

14.5.5.Cumulative Reduction Floor. In no event will the aggregated royalty amount due to BioShin in any given Pfizer Quarter during the BioShin Royalty Term for any Licensed Product in a country in the BioShin Territory be reduced under this Section 14.5 (Royalty Adjustments) by more than [***] of the amount that otherwise would have been due and payable to BioShin in such Pfizer Quarter for such Licensed Product in the BioShin Territory under Section 14.4 (Royalties). Notwithstanding the foregoing, any excess amounts that would have otherwise been deducted in such Pfizer Quarter with respect to a Licensed Product shall be deducted from the royalty amounts payable to Pfizer in successive Pfizer Quarters until the earlier to (a) such excess amounts have been deducted in full or (b) the end of the Royalty Term.
