 (f) No Right to Subcontract. Consultant shall not have the right to subcontract any
Services to be provided by it hereunder without the express prior written consent of Client, which may be withheld in Client’s sole discretion. 

3. Relationship of Parties. 

(a) Independent Contractor. Consultant is an independent contractor and is not an agent or employee of, and has no authority to bind,
Client by contract or otherwise. Consultant will perform the Services under the general direction of Client, but Consultant shall determine, in Consultant’s sole discretion, the manner and means by which the Services are accomplished, subject
to the requirement that Consultant shall at all times comply with applicable law. 
 (b) Employment Taxes. If any payment required to
be made hereunder is subject to any withholding taxes imposed by any governmental authority, Consultant shall pay such taxes to the relevant authorities as required by law. 

4. Intellectual Property Rights. Consultant agrees that it will promptly make full written disclosure to Client, hold in trust for the
sole right and benefit of Client, and does hereby assign to Client, or its designee, all its right, title, and interest in and to any and all inventions, original works of authorship, developments, concepts, improvements, designs, discoveries,
ideas, trademarks and trade secrets, whether or not patentable or registrable under copyright, trademark or similar laws, which Consultant may solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or
reduced to practice, in the course of its performance of Services for Client (collectively referred to as “Work Product”). Consultant further acknowledges that, to the extent permitted by law, all original works of authorship
which are made by it (solely or jointly with others) in the course of its performance of Services for Client under this Agreement and which are protectable by copyright shall be deemed “works made for hire,” as that term is defined in the
United States Copyright Act. Consultant understands and agrees that the decision whether or not to commercialize or market any Work Product is within Client’s sole discretion and for Client’s sole benefit and that no royalty will be due to
Consultant as a result of Client’s efforts to commercialize or market any such Work Product. Consultant agrees to provide Client such assistance as is reasonably necessary to obtain or perfect any such rights, including but not limited to
executing and delivering to Client any documents required to apply for patents, register copyrights or to obtain other protections, upon Client’s request and at Client’s sole expense. Consultant forever waives and releases to Client all
rights and benefits accorded under any law with respect to Work Product, including but not limited to the law known as “droit moral,” unfair competition or trade secret laws, or any similar provisions. Client, within its sole
discretion, will be entitled to itself amend, change or modify any Work Product or to engage any third party to amend, change or modify any Work Product.

 5. Confidential Information. 

(a) Each party (“Recipient”) acknowledges that it may acquire information and materials from the other
party (“Discloser”) and knowledge about trade secrets and know-how of the other party contained in the business, activities and strategies of the Recipient and that all such knowledge and information acquired are and will be
the confidential and proprietary information of Discloser (collectively, the “Confidential Information”). Recipient agrees to hold all such Confidential Information in strict confidence, and not to disclose it to others or
use it in any way, commercially or otherwise, except that Recipient may disclose it to Recipient’s employees and subcontractors on a need-to-know basis and only to employees and subcontractors who are under a like obligation of confidentiality,
and not to allow any unauthorized person access to it, either before or after expiration or termination of this Agreement. Recipient further agrees to use commercially reasonable efforts to protect the confidentiality of the Confidential Information
including, without limitation, implementing and enforcing operating procedures to minimize the possibility of unauthorized use or copying of the Confidential Information.  

(b) Notwithstanding the foregoing, this Agreement imposes no obligation upon Recipient with respect to Confidential Information, which the
Recipient can show by competent documentation, that (i) was in Recipient’s possession before receipt from Discloser; (ii) is or becomes a matter of public knowledge through no fault of Recipient; (iii) is rightfully received by
Recipient from a third party without a duty of confidentiality; (iv) is disclosed by Discloser to a third party without a duty of confidentiality on the third party; (v) is independently developed by Recipient without use of or reference
to such Confidential Information; (vi) is disclosed by Discloser with Recipient’s prior written approval; or (vii) is required to be disclosed by a government body or court of law. If Recipient is required by a government body or
court of law to disclose Confidential Information, prior to such required disclosure, Recipient shall give Discloser reasonable advance notice of any such disclosure and shall cooperate with Discloser in protecting against any such disclosure and/or
obtaining a protective order narrowing the scope of the such disclosure and/or use of the Confidential Information.

not been affected within said thirty (30) days, this Agreement may, within the sole discretion of the non-breaching party, automatically terminate, effective as of the date specified in the notice. All termination rights shall be in addition to
