 1.2 From time to time during
the term of this Agreement (including any extension or renewal term thereof) upon request by the Company, the Consultant shall provide consulting and advisory services to the Company and its Affiliates and their respective management, employees and
agents at reasonable times agreed upon by the Consultant and the Company at the Company’s offices, or such other locations as may be agreed upon by the Consultant and the Company. The Consultant agrees to provide to the Company and its
management, employees and agents, at the Company’s request, consultation as provided herein by telephone, by electronic mail, by audioconference, by videoconference and/or through written correspondence.

not copyrightable, made, discovered, conceived, developed, generated, contributed to, or first reduced to practice by the Consultant, either alone or jointly with others, while performing or arising from the services provided hereunder
(collectively, “Inventions”). The Consultant understands and agrees that all Inventions are and shall remain the exclusive property of the Company and shall be treated as Confidential Information (as defined in Section 6 below). The

 5.5 This Section 5 will survive the expiration or termination of this Agreement. 
 6. Confidentiality. 
 6.1 The Consultant acknowledges that, during the course of performing the consulting services hereunder, confidential and proprietary information (i) owned by the Company and/or its Affiliates (e.g., technical information, business
plans, identification or characterization of biological or other materials, results and/or design of experiments and/or preclinical or clinical testing, financial analysis or marketing plans), and/or (ii) received by the Company and/or its
Affiliates in confidence from one or more third parties, may, in each case, be disclosed to the Consultant by or on behalf of the Company, and that in connection with the consulting activities conducted by Consultant under this Agreement the
Consultant will be developing information and creating work product related to the Field (e.g. inventions, projects, products, potential customers, personnel, business plans, finances and/or other commercially valuable information). All such
information described in the previous sentence, whatever its form or medium (whether in written, oral, electronic, or graphic format), shall be referred to as “Confidential Information.” The Consultant acknowledges and agrees that the
Company’s business area is extremely competitive, that the success of the Company’s business is dependent in part upon the maintenance of secrecy of Confidential Information, and that any disclosure of the Confidential Information would
result in serious harm to the Company. 
 6.2 The Consultant agrees that the Confidential Information of the Company will be used by the
Consultant only in connection with the consulting services hereunder, and will not be used in any way that is detrimental to the Company. 
 6.3 The Consultant agrees to hold in strict confidence and not to disclose, directly or indirectly, the Confidential Information of the Company to any third person or entity, other than representatives or agents of the Company. 

6.4 The term “Confidential Information” does not include information to the extent that it (i) is or becomes generally available to the
public other than through breach of this Agreement or other wrongful act by the Consultant, (ii) was already lawfully within the Consultant’s possession prior to being furnished to the Consultant by or on behalf of the Company hereunder,
or (iii) becomes available to the Consultant on a nonconfidential basis from a third party who has no obligation of confidentiality to the Company or any of its Affiliates. Specific Confidential Information shall not be deemed to be within any
of the foregoing exclusions merely because it is within the scope of more general information within one or more of the exclusions. Further, any combination of Confidential Information (whether or not combined with non-confidential information)
shall not be deemed to be within the above exceptions merely because one or more individual items of Confidential Information are within the above exceptions. 
 6.5 The Consultant may disclose any Confidential Information that is required to be disclosed by applicable law, government regulation or court order; provided that if any such disclosure is required, the Consultant
shall give the Company reasonable advance notice of any such contemplated disclosure so that the Company may seek a protective order or take other action reasonable in light of the circumstances to prevent and/or limit the scope of any such
disclosure.

Consultant or produced by the Consultant in connection with services rendered hereunder, together with all copies, excerpts, summaries and abstracts of any of the foregoing. Notwithstanding such return or destruction, as the case may be, the

this Agreement (including any extension or renewal term thereof).

liabilities under this Agreement to any of its Affiliates or to a successor to all or a substantial part of its business or assets without the consent of the Consultant. Subject to the foregoing, this Agreement will inure to the benefit of and be

determine what discovery will be permitted, and shall not order or require discovery against either party of a type or scope that is not permitted against the other party because of differences in applicable law. The costs of the arbitration shall
be shared equally by the parties, and each party shall bear its own costs and attorneys’ and witness’ fees. No punitive damages may be granted by the arbitrator. The parties agree that the arbitrator’s decision shall be the sole,
exclusive and binding remedy between them regarding any and all disputes, controversies, claims and counterclaims presented to the arbitrator.
