(c) any material breach by Pharmavant of any of its representations, warranties, covenants, agreements, or obligations under this Agreement;provided, that, in each case ((a)-(c)), such indemnity shall not apply to the extent Eisai has an indemnification obligation pursuant to Sections 9.2(a), 9.2(b), 9.2(c) or 9.2(d) for such Damages.

9.2 Indemnification by Eisai. Eisai shall indemnify and hold harmless Pharmavant, its Affiliates, and its and their respective directors, officers, employees, agents, successors, and assigns (collectively, the “Pharmavant Indemnitees”), from and against any and all Damages to the extent arising out of or relating to, directly or indirectly, any Third Party Claim based upon:

9.3 Procedure.

9.3.1 Indemnification Claim Notice. If a Party is seeking indemnification under Section 9.1 or Section 9.2, as applicable (the “Indemnitee”), it shall inform the other Party (the “Indemnitor”) of the claim giving rise to the obligation to indemnify pursuant to Section 9.1 or Section 9.2, as applicable, as soon as reasonably practicable after receiving notice of the Third Party Claim (an “Indemnification Claim Notice”); provided, that, any delay or failure to provide such notice shall not constitute a waiver or release of, or otherwise limit, the Indemnitee’s rights to indemnification under Section 9.1 or Section 9.2, as applicable, except to the extent that such delay or failure materially prejudices the Indemnitor’s ability to defend against the relevant Third Party Claim.

9.3.2 Right to Assume Defense. The Indemnitor shall have the right, upon written notice given to the Indemnitee within [***] after receipt of the Indemnification Claim Notice, to assume the defense of any such Third Party Claim for which the Indemnitee is seeking indemnification pursuant to Section 9.1 or Section 9.2, as applicable. The Indemnitee shall cooperate with the Indemnitor and the Indemnitor’s insurer as the Indemnitor may reasonably request, [***]. The Indemnitee shall have the right to participate, [***] and with counsel of its choice, in the defense of any Third Party Claim that has been assumed by the Indemnitor.

9.3.3 Right to Settle. The Indemnitor shall not settle any Third Party Claim without first obtaining the prior written consent of the Indemnitee, not to be unreasonably withheld, conditioned, or delayed; provided, that, the Indemnitor shall not be required to obtain such consent if the settlement: (a) involves only the payment of money and shall not result in the Indemnitee (or other Eisai Indemnitees or Pharmavant Indemnitees, as applicable) becoming subject to injunctive or other similar type of relief; (b) does not require an admission by the Indemnitee (or other Eisai Indemnitees or Pharmavant Indemnitees, as applicable); and (c) does not adversely affect the rights or licenses granted to the Indemnitee (or its Affiliate) under this Agreement. The Indemnitee shall not settle or compromise any such Third Party Claim without first obtaining the prior written consent of the Indemnitor.

9.3.4 Disputes. If the Parties cannot agree as to the application of Section 9.1 or Section 9.2, as applicable, to any Third Party Claim, pending the resolution of the dispute pursuant to Section 11.6.2, the Parties may conduct separate defenses of such claims, with each Party retaining the right to claim indemnification from the other Party in accordance with Section 9.1 or Section 9.2, as applicable, upon resolution of the underlying Third Party Claim. In each case, the Indemnitee shall reasonably cooperate with the Indemnitor and shall make available to the Indemnitor all pertinent information under the control of the Indemnitee, which information shall be subject to Article 7.

9.4 Insurance. Each Party shall maintain a program of insurance or self-insurance sufficient to fulfill its obligations under this Agreement which are [***] at all times during which the Licensed Compound or any Licensed Product is being clinically tested in human subjects or commercially distributed or sold. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 9. Each Party shall provide the other Party with written evidence of such insurance upon request, which evidence shall be treated as such Party’s Confidential Information. Each Party shall provide the other Party with written notice at least [***] prior to the cancellation, nonrenewal or material change in such insurance.

9.5 LIMITATION OF LIABILITY. NEITHER PARTY NOR ANY OF THEIR RESPECTIVE AFFILIATES, WILL BE LIABLE TO THE OTHER PARTY OR ITS AFFILIATES UNDER OR IN CONNECTION WITH THIS AGREEMENT FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR PUNITIVE OR EXEMPLARY DAMAGES (INCLUDING LOST PROFITS OR LOST REVENUES), WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY, CONTRIBUTION, OR OTHERWISE, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THATPARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE. [***].

10.2 Termination for Material Breach.

10.2.1 Termination Notice. This Agreement may be terminated in its entirety or on a Licensed Product-by-Licensed Product or country-by-country basis by a Party for the material breach by the other Party of this Agreement; provided, that, the breaching Party has not cured such breach within [***]after the date of written notice to the breaching Party of such breach (the “Cure Period”), which notice shall describe such material breach in reasonable detail and shall state the non-breaching Party’s intention to terminate this Agreement. Notwithstanding the foregoing, if such material breach by its nature cannot be cured within the foregoing Cure Period or is incurable, but the consequences of such breach can be reasonably alleviated but not within the foregoing

Cure Period, then such Cure Period shall be extended if, prior to the end of the initial [***] Cure Period, the non-terminating Party provides a reasonable written plan for curing or reasonably alleviating the consequences of such material breach and thereafter uses Commercially Reasonable Efforts (or commercially reasonable efforts where Eisai is the breaching Party) to cure or alleviate such material breach in accordance with such written plan. Notwithstanding the foregoing, in no event shall such Cure Period extend for more than [***] after the breaching Party provides such written plan to the other Party, subject to Section 10.2.2.

Notwithstanding Section 10.2.1, if the Parties in good faith disagree as to whether there has been a material breach of this Agreement, then: (a) the Party that disputes whether there has been a material breach may contest the allegation by referring such matter, within [***] following its receipt of notice of alleged material breach, for resolution in accordance with Section 11.6.2; (b) unless otherwise determined by the arbitrators pursuant to Section 11.6.2, the relevant Cure Period with respect to such alleged material breach shall be tolled from the date on which the Party that disputes whether there has been a material breach notifies the other Party of such dispute and through the resolution of such dispute in accordance with the applicable provisions of this Agreement; and (c) during the pendency of such dispute, all of the terms and conditions of this Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder.

10.3 Termination for Challenge. Except to the extent the following is unenforceable under the Applicable Law of a particular jurisdiction where a Patent within any Eisai Product Patents or Eisai Patents, is pending or a patent within any such Patents issued, Eisai may terminate this Agreement in its entirety or on a Licensed Product-by-Licensed Product or country-by-country basis upon written notice if Pharmavant or any of its Affiliates, Sublicensees or distributors initiates a Challenge or Assists a Third Party in initiating a Challenge.

10.4 Termination for Bankruptcy.

10.4.1 If either Party makes a general assignment for the benefit of, or an arrangement or composition generally with, its creditors, appoints or suffers appointment of an examiner or of a receiver or trustee over all or substantially all of its property, passes a resolution for its winding up, or files a petition under any bankruptcy or insolvency act or law or has any such petition filed against it which is not dismissed, discharged, bonded, or stayed within [***] after the filing thereof (each, an “Insolvency Event”), the other Party may terminate this Agreement in its entirety, effective immediately upon written notice to such Party.

10.4.2 If this Agreement is terminated due to the rejection of this Agreement by or on behalf of Eisai due to an Insolvency Event, all licenses and rights to licenses granted under or pursuant to this Agreement by Eisai to Pharmavant are and shall otherwise be deemed to be licenses of rights to “intellectual property.” The Parties agree that Pharmavant, as a licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections

under any applicable insolvency statute, and that upon commencement of an Insolvency Event by or against Eisai, Pharmavant shall be entitled to a complete duplicate of or complete access to (as Pharmavant deems reasonably appropriate) any such intellectual property and all embodiments of such intellectual property. Such intellectual property and all embodiments thereof shall be promptly delivered to Pharmavant: (a) upon any such commencement of a bankruptcy proceeding (or other Insolvency Event) upon written request therefore by Pharmavant, unless Eisai elects to continue to perform all of its obligations under this Agreement; or (b) if not delivered pursuant to (a) above, upon the rejection of this Agreement by or on behalf of Eisai, then upon written request therefore by Pharmavant. The provisions of this Section 10.4.2 shall be: (i) without prejudice to any rights Pharmavant may have arising under any applicable insolvency statute or other Applicable Law; and (ii) effective only to the extent permitted by Applicable Law.

10.5 [***].

The Eisai Transition Plan shall provide that Pharmavant shall:

(i) where permitted by Applicable Law, transfer to Eisai all of its right, title and interest in all Regulatory Materials then Controlled by Pharmavant that are solely applicable to the Terminated Products in the Terminated Territory, or to the extent not so transferrable, Pharmavant shall take all reasonable actions to make available to Eisai or its designee the benefits of such Regulator Materials, including upon Eisai’s request, by providing a right of reference to such Regulatory Materials Controlled by Pharmavant for the Terminated Products on the effective date of termination, to the extent necessary for Eisai to Develop and Commercialize Terminated Products;

(v) if requested by Eisai, use Commercially Reasonable Efforts to assign any agreements with Third Parties that relate solely to the Terminated Product in the Terminated Territory which Pharmavant has in place on the effective date of termination with respect to the conduct of Clinical Trials for Terminated Products for the Terminated Territory or the Manufacture of Terminated Products for the Terminated Territory (including agreements with contract manufacturing organizations, contract research organizations, clinical sites and investigators), or, to the extent any such Third Party agreement is not assignable to Eisai, at Eisai’s request and expense, use Commercially Reasonable Efforts to arrange to continue to provide such services for a reasonable time after termination (to the extent permitted under the agreement with such Third Party) and to facilitate Eisai’ s entry into a replacement agreement with such Third Party for such services;

(vi) [***] solely upon Eisai’s request made within [***] from the effective date of termination, transfer to Eisai any supplies of any Terminated Products for the Terminated Territory in the inventory of Pharmavant or any Affiliate or contractor of Roivant Sciences (it being understood that Eisai shall have the right, but not the obligation, to purchase any such Terminated Products), [***];

(vii) provide Eisai with copies of all Know-How included within the license set forth in Section 10.6.1(b) that solely relate to any Terminated Product in the Terminated Territory that have not previously been provided to Eisai; provided, that, with respect to any such Know-How that Pharmavant or its Affiliates maintains as a trade secret, Pharmavant may impose restrictions on Eisai’s maintenance and use of such Information or provide Eisai the benefit of such Information without providing or disclosing such Information to Eisai;

(viii) transfer to Eisai all of its right title and interest in all Pharmavant Trademarks that are solely applicable to the Terminated Products in the Terminated Territory; and

(ix) if Pharmavant is Manufacturing or is having Manufactured the Licensed Compound, Licensed Products or any intermediate of such Licensed Products as of the date of termination, Pharmavant shall use Commercially Reasonable Efforts to (A) transfer copies of any documents and materials Controlled by Pharmavant as of the effective date of termination and embodying Pharmavant IP that is at the time of such termination being used by Pharmavant or its Third Party manufacturers to Manufacture the Licensed Compound and any Licensed Products, including but not limited to all suppliers, analytical methods, quality standards, specifications, commercial active pharmaceutical ingredient formula, process chemistry, Manufacturing process descriptions, process flows, cycle times, process parameters, process equipment type and sizes, cleaning methods, commercial active pharmaceutical ingredient samples, master safety data sheets, and stability reports (the “Pharmavant Manufacturing Know-How”) to enable the Manufacture of any Terminated Products by Eisai, its Affiliates or any Third Party manufacturer of Eisai, in each case to the extent that such Pharmavant Manufacturing Know-How was not transferred to Pharmavant or such Third Party(ies) by Eisai or its Affiliates or their respective Third Party manufacturers or is otherwise already known to Eisai, its Affiliate or their

respective Third Party manufacturers; and (B) promptly make available to Eisai or any such Third Party manufacturer a reasonable number of appropriately trained personnel to provide, on a mutually convenient timetable, reasonable technical assistance in the transfer of Pharmavant Manufacturing Know-How to Eisai.

(e) The provisions of Article 6 (other than Section 6.1) shall be terminated with respect to the Licensed Product and Eisai shall have the right to assume all Prosecution and Maintenance and enforcement activities under Article 6 with respect to Eisai Patents as to which Pharmavant has assumed the right and authority to Prosecute and Maintain or enforce and Pharmavant will cooperate with Eisai and provide Eisai with reasonable assistance in connection with the transfer of such Prosecution and Maintenance and enforcement activities with respect to such Eisai Patent.

(f) If this Agreement is terminated only with respect to a given country or geographic region or only with respect to a given Licensed Product, then the foregoing effects of termination shall only apply with respect to the terminated country or geographic region or Licensed Product (and, for clarity, the terms and conditions of this Agreement will continue with respect to all other countries and geographic regions and Licensed Products). For the avoidance of doubt, if this Agreement is terminated only with respect to a given country or geographic region or only with respect to a given Licensed Product, Article 6 shall continue to survive and apply after any such termination during the Term on a global basis; provided, that, Eisai’s continued Development, Manufacture and Commercialization of the Terminated Products in the Terminated Territory in accordance with this Section 10.6.1(f) will not be subject to Section 6.2.2.

(g) Any and all sublicense agreements entered into by Pharmavant or any of its Affiliates with a Sublicensee pursuant to this Agreement shall survive such termination of this Agreement, except to the extent that: (i) any such Sublicensee is in material breach of this Agreement or such sublicense agreement; or (ii) Eisai elects to grant such Sublicensee a direct license of the sublicensed rights on the same terms applicable to Pharmavant under this Agreement. Pharmavant shall, upon the written request of Eisai, assign any such sublicense (to the extent not terminated pursuant to the preceding sentence) to Eisai or its Affiliates and, upon such assignment, Eisai or its Affiliates, as applicable, shall assume such sublicense.

10.6.2 Termination by Pharmavant for Material Breach or Bankruptcy. Upon termination of this Agreement by Pharmavant in accordance with Section 10.2 or Section 10.4, Pharmavant shall have the right, by providing written notice to Eisai on or before[***] from the effective date of such termination, to have the following apply:

(a) the licenses set forth in Section 2.1 with respect to the Licensed Compound and any Licensed Products in all countries in the Territory shall remain in effect; subject to Pharmavant’s continued compliance with the terms of this Agreement; and

(b) the provisions of Article 6 shall remain in effect; provided, however, Eisai’s rights in respect of Joint Patents in the Territory shall terminate and Pharmavant shall have the right to assume all Prosecution and Maintenance and enforcement activities under Article 6 with respect to Joint Patents as to which Eisai has assumed the right and authority to Prosecute and Maintain or enforce.

10.7 Surviving Provisions.

10.7.1 Accrued Rights; Remedies. The expiration or termination of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such expiration or termination, and any and all damages or remedies (whether at law or in equity) arising from any breach hereunder, each of which shall survive expiration or termination of this Agreement. Such expiration or termination shall not relieve any Party from obligations which are expressly indicated to survive expiration or termination of this Agreement. Except as otherwise expressly set forth in this Agreement, the termination provisions of this Article 10 are in addition to any other relief and remedies available to either Party under this Agreement, at law, or in equity.

10.7.2 Survival. Without limiting the provisions of Section 10.6 (and any Sections referenced therein), the rights and obligations of the Parties set forth in the following Sections and Articles of this Agreement shall survive the expiration or termination of this Agreement, in addition to those other terms and conditions that are expressly stated to survive termination or expiration of this Agreement: Article 1 (to the extent the definitions are used in other surviving provisions), Section 2.5, Sections 5.2, 5.3, 5.4 and 5.5 (solely in case of termination and solely with respect to amounts accrued prior to termination but not paid), Section 6.1, Sections 6.2.6, 6.3.1, 6.3.4, 6.3.10 and 6.3.11 (respectively, with respect to Joint Patents and Joint IP), Section 6.4, Sections 7.1, 7.2, 7.3, 7.4, 7.5 and 7.10, Section 8.5, Article 9, Section 10.1.2 (solely in case of expiration), Section 10.6 and Section 10.7 and Article 11.

ARTICLE 11

MISCELLANEOUS

11.1 Severability. If one or more of the terms or provisions of this Agreement is held by a court of competent jurisdiction to be void, invalid, or unenforceable in any situation in any jurisdiction, such holding shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the void, invalid, or unenforceable term or provision in any other situation or in any other jurisdiction, and the term or provision shall be considered severed from this Agreement solely for such situation and solely in such jurisdiction, unless the void, invalid, or unenforceable term or provision is of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the void, invalid, or unenforceable term or provision. If the final judgment of such court declares that any term or provision hereof is void, invalid, or unenforceable, the Parties agree to: (a) reduce the scope, duration, area, or applicability of the term or provision or to delete specific words or phrases to the minimum extent necessary to cause such term or provision as so reduced or amended to be enforceable; and (b) make a good-faith effort to replace any void,invalid, or unenforceable term or provision with a valid and enforceable term or provision such that the objectives contemplated by the Parties when entering this Agreement may be realized.

11.2 Notices.

A Party may add, delete, or change the person or address to which notices should be sent at any time upon written notice delivered to the other Parties in accordance with this Section 11.2.

11.3 Assignment. Neither Party may assign this Agreement or assign or transfer any rights or obligations hereunder without the prior written consent of the other Party, except that a Party may make such an assignment or transfer without the other Party’s consent (a) to any Affiliate of such Party (including for internal restructuring purposes), provided, that, such transfer shall not adversely affect the other Party’s rights and obligations under this Agreement and that such assigning/transferring Party (or its successor entity to the extent such Party is no longer in existence) remains jointly and severally liable with such Affiliate for the performance of this

Agreement or the assigned obligations, or (b) to any Third Party successor-in-interest in connection with a Change of Control Transaction of such Party; provided, that, in each case (a) and (b) that the assigning Party provides written notice to the other Party of such assignment and the assignee shall have agreed in writing to be bound (or is otherwise required by operation of Applicable Law to be bound) in the same manner as such assigning Party hereunder; provided, further, that, no such written notice shall be required in connection with any permitted assignment to any Affiliate of such Party for internal restructuring purposes.

Any permitted assignment shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this Section 11.3 shall be null, void and of no legal effect. For clarity, the provisions of this Section 11.3 shall not apply to or encompass sublicensing of the rights licensed to a Party under this Agreement. [***].

11.4 Waivers and Modifications. The failure of any Party to insist on the performance of any obligation hereunder shall not be deemed to be a waiver of such obligation. Waiver of any breach of any provision hereof shall not be deemed to be a waiver of any other breach of such provision or any other provision on such occasion or any succeeding occasion. No waiver, modification, release, or amendment of any obligation under or provision of this Agreement shall be valid or effective unless in writing and signed by the Parties.

11.5 WAIVER OF JURY TRIAL.

11.6.2 Dispute Resolution.

(a) Disputes. The Parties hereby agree that, unless otherwise stipulated in this Agreement, the procedures set forth in this Section 11.6.2 shall be the exclusive mechanism for resolving any dispute (whether in contract, tort, or otherwise), controversy, or claim between the Parties arising out of or in connection with this Agreement, any Party’s rights or obligations under this Agreement, breach of this Agreement, or the transactions contemplated by this Agreement (each, a “Dispute”).

(b) Notice; Selection of Arbitrators. Either Party may refer any Dispute to arbitration by submitting a written notice of such request to the other Party. Such Dispute shall be finally resolved by binding arbitration in accordance with the Rules of Arbitration of the International Chamber of Commerce (“ICC”), except to the extent the foregoing conflicts with this Section 11.6.2, in which case this Section 11.6.2 shall control. In any such arbitration, (i) the panel will be comprised of one arbitrator chosen by Eisai, one arbitrator chosen by Pharmavant and one arbitrator, who shall act as the chairman of the panel, chosen by the two co-arbitrators; and (ii) if either Party fails or both Parties fail to choose an arbitrator or arbitrators within [***] after receiving notice of commencement of arbitration or if the two arbitrators fail to choose a third arbitrator within [***] after their appointment, then either or both Parties shall immediately request that the ICC select the remaining number of arbitrators to be selected. The arbitrators shall be neutral and independent of the Parties and their respective Affiliates, and may not be current or former directors, officers or employees of the Parties or their respective Affiliates. No party may have any ex parte discussion with any potential arbitrator, except for confirming if such arbitrator is willing and able to serve on the arbitration panel. All arbitrators shall have ten (10) or more years of experience in the pharmaceutical and biotechnology industries, shall have appropriate experience with respect to the matter(s) to be arbitrated, and shall have some experience in mediating or arbitrating issues relating to such agreements. In the case of any Dispute involving an alleged failure to use Commercially Reasonable Efforts, the arbitrators shall, in addition, have experience and expertise in the worldwide development, manufacture and commercialization of pharmaceuticals and the business, legal and scientific considerations related thereto. An arbitrator will be deemed to meet these qualifications unless a Party objects within[***] after the arbitrator is nominated. In the case of a Dispute involving a scientific or accounting matter or determination, an expert having applicable expertise and experience will be selected by the Parties to assist the arbitrators in such scientific or accounting matter or determination (and the arbitrators will select such expert if the Parties cannot agree on such expert within [***] following the selection of the arbitrators). The governing law in Section 11.6.1 shall govern such proceedings. No individual will be appointed to arbitrate a Dispute pursuant to this Agreement unless he or she agrees in writing to be bound by the provisions of this Section 11.6.2. The place of arbitration will be in New York, NY unless otherwise agreed to by the Parties, and the arbitration shall be conducted in English.

(c) Arbitration Hearing. The arbitrators shall set a date for a hearing that shall be held no later than [***] following the appointment of the last of such three (3) arbitrators. The Parties shall have the right to be represented by counsel.

No less than [***] prior to the hearing, each Party shall submit the following to the other Party and the arbitration panel: (i) a copy of all exhibits on which such Party intends to rely in any oral or written presentation to the panel; (ii) a list of any witnesses such Party intends to call at the hearing, and a short summary of the anticipated testimony of each witness; and (iii) a brief in support of such Party’s proposed rulings and remedies; provided, that the brief shall not exceed twenty-five (25) pages. This page limitation shall apply regardless of the number of issues raised in the arbitration proceeding. Unless the Parties agree otherwise, no discovery shall be required or permitted by any means, including depositions, interrogatories, requests for admissions, or production of documents. The arbitration panel shall have sole discretion regarding the admissibility of any evidence, except statements made during settlement negotiations and affidavits prepared for the purposes of the hearing shall not be admissible.
