3.                                      ARENA AGREEMENTS

3.1                               Development Agreement and Related Agreements.

(a)                                 Roivant will seek to enter into a development, marketing and supply agreement with Arena relating to the Product Opportunity (the “Development Agreement”).  Roivant will have no obligation to enter into the Development Agreement except on such terms and conditions as are acceptable to it in its sole and exclusive discretion.  Roivant may execute amendments, side letters and other agreements with Arena or its affiliate Arena Pharmaceuticals, Inc. relating to the Development Agreement as it sees fit in in its sole and exclusive discretion until such time as it receives the Exercise Notice (as defined below) (the Development Agreement, as may be amended, together with any such related side letters and agreements, the “Arena Agreements”).

(b)                                 Within ten (10) business days following the execution of the Development Agreement, Roivant will provide Axovant with a true, correct and legible copy of the Development Agreement.  If Roivant executes any amendments, side letters or other agreements with Arena or its affiliate Arena Pharmaceuticals, Inc. relating to the Development Agreement prior to the expiration of the Option Exercise Period, then within ten (10) business days following the execution of such document, Roivant will provide Axovant with a true, correct and legible copy of such document.

(c)                                  Following Roivant’s receipt of the Exercise Notice, Roivant will not enter into any amendment to the Development Agreement, nor any side letter or other agreement with Arena relating to the Development Agreement, without Axovant’s prior written consent.

3.2                               Covenant.  Subject to Section 3.3, unless and until the Option (as defined below) has terminated unexercised, Roivant will not grant to any Person any rights under the Arena Agreements or with respect to the Product, whether by assignment, transfer, license, sublicense or otherwise, except with Axovant’s express prior written consent.  Notwithstanding the foregoing, Roivant may grant a non-exclusive sublicense under such rights to contractors performing work under the Development Program solely to conduct such work, without such consent from Axovant, provided that the agreement between Roivant and such contractor under which such work is performed can be assigned to Axovant without such contractor’s consent in connection with Axovant’s exercise of the Option.

3.3                               Right of First Refusal.  Unless and until the Option (as defined below) has terminated unexercised, Axovant will have a right of first refusal as follows:  Roivant will not grant to any Person any rights under the Arena Agreements, whether by assignment, transfer, license, sublicense or otherwise, until Roivant has first provided to Axovant a reasonably detailed set of written terms upon which Roivant would be willing to grant such rights (the “Roivant Notice”).  If Axovant notifies Roivant in writing within thirty (30) days of Axovant’s receipt of such notice that Axovant is interested in acquiring such rights (the “Axovant Notice”), then the Parties will negotiate in good faith a definitive agreement to grant Axovant such rights on such terms.  If Axovant does not notify Roivant within thirty (30) days of Axovant’s receipt of the Roivant Notice that it wishes to negotiate the agreement described in the Roivant Notice, or if the Parties fail to execute a definitive agreement for such rights within sixty (60) days of the Axovant Notice (the later of such applicable date referred to as the “RoFR Expiration Date”), then Roivant may grant such rights to a third party, provided that (i) the terms on which Roivant

3

grants such rights to such third party are not more favorable to such third party than the terms last offered to Axovant in writing by Roivant and (ii) the definitive binding agreement(s) with respect to the grant of such rights to the third party is entered into no later than sixty (60) days of the RoFR Expiration Date.  Notwithstanding the foregoing, Roivant may grant a non-exclusive sublicense under such rights to contractors performing work under the Development Program solely to conduct such work without triggering the right of first refusal set forth in this Section, provided that the agreement between Roivant and such contractor under which such work is performed can be assigned to Axovant without such contractor’s consent in connection with Axovant’s exercise of the Option.

4.                                      OPTION

4.1                               Grant of Option.  Roivant hereby grants to Axovant an option to receive an assignment and assume all of Roivant’s right, title and interest in and to the Arena Agreements, the Product and the Development Program (the “Option”), subject to the terms and conditions of this Article 4.

4.4                               Termination of Option.  If Roivant does not receive the Exercise Notice prior to the expiration of Option Exercise Period, then the Option will terminate and Roivant will have no further obligation to Axovant with respect to the Product or the Arena Agreements.

4.5                               Effect of Option Exercise.

(a)                                 Statement of Reimbursable Costs; Other Information.  Within ten (10) days of Roivant’s receipt of the Exercise Notice, Roivant will provide Axovant with (i) a statement of all Reimbursable Costs incurred to date and all further Reimbursable Costs reasonably anticipated by Roivant to be incurred prior to the completion of the transfer of the Development Program to Axovant, together with any supporting documentation reasonably requested by Axovant, and (ii) to the extent that any documents or information described in Section 4.6(a) or (b) exists but has not yet been provided to Axovant, such documents and information.

(b)                                 Assignment of Arena Agreements.  Within ten (10) days of Roivant’s provision of the documents and information described in subsection (a) above, Roivant will assign to Axovant all of Roivant’s right, title and interest in and to the Arena Agreements, unless Axovant provides written notice to Roivant that it will not accept the assignment.  If Axovant provides such notice, then the Option will be deemed to be terminated with the effects set forth in Section 4.4.

(d)                                 Reimbursable Costs.  If Axovant exercises the Option and accepts the assignment of the Arena Agreements, then it will reimburse Roivant for one hundred and ten percent (110%) of Roivant’s Reimbursable Costs, as follows:  Within thirty (30) days following Roivant’s receipt of the Exercise Notice, Roivant will provide to Axovant an invoice and accounting of its Reimbursable Costs through such date, together with any supporting documentation reasonably requested by Axovant, and Axovant will pay such invoices (if undisputed) within thirty (30) days of receipt.  Thereafter, Roivant will provide to Axovant an invoice and accounting of its Reimbursable Costs on a monthly basis, together with any supporting documentation reasonably requested by Axovant, and Axovant will pay such invoices (if undisputed) within thirty (30) days of receipt.  If Axovant disputes any invoice, the Parties will promptly confer and attempt to resolve such dispute in good faith.  Notwithstanding the foregoing, Axovant will have no obligation to reimburse any Reimbursable Costs that, prior to the calculation of the ten percent (10%) mark-up described above, are more than ten percent (10%) in excess of the amounts stated in the statement of Reimbursable Costs provided by Roivant pursuant to subsection (a) above.

(e)                                  Transition of Development Program and Development IP.  Concurrently with the assignment of the Arena Agreements, the Parties will cooperate to transfer to Axovant as expeditiously as practicable full responsibility for the Development Program, including all regulatory filings and correspondence (including, without limitation IND No. 73405 (serial number 0031)), contracts, documentation and databases relating to the Development Program or the Product.  Upon Axovant’s reasonable request, Roivant will provide reasonable assistance to enable Axovant to utilize the Development IP in the development and commercialization of the Product in the Field.

Roivant will maintain books and records pertaining to the Development Program and will make them available for inspection and audit, at Axovant’s expense, by a mutually acceptable independent certified public accounting firm during normal business hours upon reasonable prior written notice to Roivant.  If Axovant exercises the Option and accepts assignment of the Arena Agreements, then Roivant’s obligations and Axovant’s rights under this Section will continue for three (3) years following the completion of the transfer of the Development Program to Axovant.

4.8                               Use of Information.  Unless and until Axovant provides the Exercise Notice to Roivant and accepts the assignment of the Arena Agreements, Axovant will use the information provided under Sections 4.6 and 4.8 solely to evaluate its interest in exercising the Option and accepting the assignment of the Arena Agreements.

4.9                               Services Agreement.  The Parties agree that the Services Agreement entered into between Roivant and Axovant as of October 31, 2014 and between Roivant, Axovant and Axovant Neurosciences, Inc.

5.                                      CONFIDENTIALITY

5.1                               Confidential Information.  Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties, and subject to the other applicable terms of this Article 5, the Parties agree that the receiving Party (the “Receiving Party”) will keep confidential and not publish or otherwise disclose or use for any purpose other than as provided for in this Agreement any information or materials, patentable or otherwise, in any form (written, oral, photographic, electronic, magnetic, or otherwise) that is disclosed to it by the other Party (the “Disclosing Party”) pursuant to this Agreement, including all information concerning any Arena Agreements, the Product, the Product Opportunity or the Development Program, and any other technical or business information of whatever nature concerning the Disclosing Party or its technology or business (collectively, “Confidential Information”  of the Disclosing Party), except that the Receiving Party may disclose Confidential Information of the Disclosing Party to its Affiliates and its and its Affiliates’ respective officers, directors, employees, agents, subcontractors and consultants with a need to know such Confidential Information to assist the Receiving Party with the activities contemplated or required of it by this Agreement (and who will be advised of the Receiving Party’s obligations hereunder and who are bound by confidentiality and non-use obligations with respect to such Confidential Information no less onerous than those set forth in this Agreement) (each, a “Recipient”).  For clarity, all information and materials provided by Arena to Roivant in connection with the Arena Agreements is deemed to be the Confidential Information of Roivant, subject to Section 5.6.  Notwithstanding the foregoing, the Parties acknowledge the practical difficulty of policing the

6

use of information in the unaided memory of the Receiving Party or its Recipients, and as such each Party agrees that the Receiving Party will not be liable for the use by any of its Recipients of specific Confidential Information of the Disclosing Party that is retained in the unaided memory of such Recipient; provided, that (a) such Recipient is not aware that such Confidential Information is the confidential information of Disclosing Party at the time of such use; (b) the foregoing is not intended to grant, and will not be deemed to grant, the Receiving Party, its Affiliates, or its Recipients (i) a right to disclose the Disclosing Party’s Confidential Information or (ii) a license under any Patents or other intellectual property right of the Disclosing Party; and (c) such Recipient has not intentionally memorized such Confidential Information for use outside this Agreement. For the purpose of this Article 5, the term “Disclosing Party” will include each Party and its Affiliates and its and their respective officers, directors, employees, agents, subcontractors and consultants who are directed or authorized to disclose such Party’s and/or its Affiliates’ Confidential Information, and the term “Receiving Party” will include each Party and its Affiliates.

5.2                               Exceptions.  Notwithstanding Section 5.1, the obligations of Section 5.1 will not apply to any specific Confidential Information that the Receiving Party thereof can demonstrate, in each case by competent evidence:

(a)                                 was already known to the Receiving Party or any of its Recipients, other than under an obligation of confidentiality, at the time of disclosure;

(b)                                 was generally available to the public or was otherwise part of the public domain at the time of its disclosure to the Receiving Party;

(d)                                 was subsequently lawfully disclosed to the Receiving Party or any of its Recipients without any obligation of confidentiality or non-use by a Person other than the Disclosing Party, and who, to the knowledge of the Receiving Party or such Recipient, did not directly or indirectly receive such information from the Disclosing Party or any of its Affiliates under an obligation of confidence; or

(e)                                  was independently developed by the Receiving Party or any of its Recipients without use of or reference to any information or materials disclosed by the Disclosing Party.

Information specific to the use of certain compounds, methods, conditions or features will not be deemed to be within the foregoing exceptions merely because such information is embraced by general disclosures in the public domain or in the possession of the Receiving Party or its Recipients.  In addition, a combination of information will not be deemed to fall within the foregoing exceptions, even if all of the components fall within an exception, unless the combination itself and its significance are in the public domain or in the possession of the Receiving Party prior to the disclosures hereunder.  Notwithstanding anything to the contrary herein, neither the act of using information in a clinical trial nor the filing of information with a governmental authority shall, for the purpose of this Article 5, in and of itself be deemed to place such information in the public domain.

(d)                                 disclosure to Third Parties in connection with due diligence or similar investigations by or on behalf of a Third Party in connection with an actual or potential marketing, distribution or supply agreement with, or license to, or collaboration with such Third Party or an actual or potential merger or acquisition or investment by such Third Party, or in connection with performance of any such license, collaboration or merger agreement, and disclosure to actual or potential Third Party investors in confidential financing documents, provided, in each case, that any such Third Party agrees to be bound by obligations of confidentiality and non-use substantially similar to the obligations of confidentiality and non-use of the Receiving Party pursuant to this Article 5, but of shorter duration if customary under the circumstances;

provided that wherever reasonable and practicable in the circumstances the recipient of any such Confidential Information will be subject to reasonable and customary obligations of confidentiality with respect to such Confidential Information.

5.4                               Notwithstanding the foregoing, in the event the Receiving Party or a Recipient is required to make a disclosure of the Disclosing Party’s Confidential Information pursuant to Section 5.3(d) to comply with a subpoena or other legal order, it shall, except where impracticable, give reasonable advance notice to the Disclosing Party of such disclosure and give the Disclosing Party a reasonable opportunity to quash such subpoena or order and to obtain a protective order requiring that the Confidential Information and documents that are the subject of such subpoena or order be held in confidence by such court or agency or, if disclosed, be used only for the purposes for which such subpoena or order was issued; and provided, further, that if such subpoena or order is not quashed or a protective order is not obtained, the Confidential Information disclosed in response to such subpoena or order will be limited to the Disclosing Party’s Confidential Information that is legally required to be disclosed in response to such subpoena or order and will still be subject to the restrictions on use set forth in this Article 5.

5.5                               Confidentiality of this Agreement and its Terms.  Except as otherwise provided in this Article 5, each Party agrees not to disclose to any third party the existence of this

8

Agreement or the terms and conditions of this Agreement without the prior written consent of the other Party, except that each Party may disclose the terms and conditions of this Agreement that are not otherwise made public as contemplated by Section 5.5 as permitted under Section 5.3.

5.6                               Effect of Assignment of Arena Agreements.  If Axovant exercises the Option and accepts the assignment of the Arena Agreements, then all Confidential Information relating to the Arena Agreements, the Product, the Product Opportunity and the Development Program will thereafter be deemed to be Axovant’s Confidential Information, such that Axovant will be deemed to be the Disclosing Party with respect to such Confidential Information and Roivant will be deemed to be the Receiving Party with respect to such Confidential Information.

6.                                      INDEMNIFICATION

6.1                               Indemnification of Axovant.  Roivant will defend, indemnify and hold harmless each of Axovant, its Affiliates, and its and their respective directors, officers and employees (collectively, the “Axovant Indemnitees”) from and against any and all losses, liabilities, damages, penalties, fines, costs and expenses (including reasonable attorneys’ fees and other expenses of litigation) (“Losses”) from any claims, actions, suits or proceedings brought by a third party, including investigation by a regulatory authority, (each, a “Third Party Claim”) against any Axovant Indemnitee to the extent arising from, based upon or occurring as a result of:  (a) the (i) negligence or willful misconduct of or (ii) violation of applicable laws or regulations by, in each case ((i) and (ii)), Roivant or any of its Affiliates or its or their respective subcontractors in conducting the Development Program or any activity relating to the Product; or (b) any breach or default by Roivant or its Affiliates or their respective employees, agents or contractors of any of the Arena Agreements or of the confidentiality provisions of this Agreement, except, in each case, that the foregoing indemnification obligations will not apply to the extent any such Third Party Claim falls within the scope of the indemnification obligations of Axovant set forth in Section 6.2, as to which Third Party Claim each Party will indemnify the other Party to the extent of its liability with respect to the Losses applicable to such Third Party Claim.

6.2                               Indemnification of Roivant.  Axovant will defend, indemnify and hold harmless each of Roivant, its Affiliates, and its and their respective directors, officers and employees (collectively, the “Roivant Indemnitees”) from and against any and all Losses from any Third Party Claims against any Roivant Indemnitee to the extent arising from, based on or occurring as a result of:  (a) if Axovant exercises the Option and accepts the assignment of the Arena Agreement, then the (i) negligence or willful misconduct of or (ii) violation of applicable laws or regulations by, in each case ((i) and (ii)), Axovant or any of its Affiliates or its or their respective subcontractors in conducting the Development Program or any activity relating to the Product; or (b) any breach or default by Axovant (or any of its Affiliates) of any of the Arena Agreements (but only if Axovant exercises the Option and accepts the assignment of the Arena Agreement) or of the confidentiality provisions of this Agreement; except, in each case, that the foregoing indemnification obligations will not apply to the extent any such Third Party Claim falls within the scope of the indemnification obligations of Roivant set forth in Section 6.1, as to which Third Party Claim each Party will indemnify the other Party to the extent of its liability with respect to the Losses applicable to such Third Party Claim.

9

6.3                               Procedure. A Party that intends to exercise its rights to defense, indemnity or hold harmless under this Article 6 (the “Indemnitee”) will promptly notify the indemnifying Party (the “Indemnitor”) in writing of any Third Party Claim in respect of which the Indemnitee intends to exercise such rights.  The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any action with respect to a Third Party Claim will only relieve the Indemnitor of its obligations under this Article 6 if and to the extent the Indemnitor is actually prejudiced thereby.  The Indemnitee will provide the Indemnitor with reasonable assistance, at the Indemnitor’s expense, in connection with the defense of the Third Party Claim.  The Indemnitor will have the right to assume and conduct the defense of the Third Party Claim with counsel of its choice.  The Indemnitee may participate in and monitor such defense with counsel of its choice, which will be at its own expense.  The Indemnitor will not settle any Third Party Claim without the prior written consent of the Indemnitee, not to be unreasonably conditioned, withheld or delayed, unless the settlement involves only the payment of money by the Indemnitor and does not involve any admission of liability or wrongdoing on the part of any Axovant Indemnitees or Roivant Indemnitees, as applicable.  So long as the Indemnitor is defending the Third Party Claim, the Indemnitee will not settle such Third Party Claim without the prior written consent of the Indemnitor, unless Indemnitee releases Indemnitor for all liability for such settlement.
